TURBO BOOST - Prepare to feel the Heat!
use Cache and Data and System partition as Swap Space
You want a really fast Device without overclocking it, but you have problems???
The responsiveness does not satisfy you?
Your device (sometimes) lags?
You have got Sense restarts after heavy use or after browsing?
After several days your phone becomes slower and slower?
You don’t like to create a swap partition on your sdcard?
You just hate unused internal memory?
Code:
Triple Swap Mod v3.04
- Unofficially Added Support For The HTC One XL
- Updated Scripts For Support Of Evita

Idea
Android devices have got RAM memory and internal eMMC memory. The eMMC is separated into several partitions (e.g. /system, /boot, /data, /cache). In former times of Android, the /cache partition was used for caching. Nowadays, in ICS times, the applications are using the /data partition to save information, libraries and cache data. So /cache is no longer used by the operating system or applications. Therefore, this partitions is empty except 4ext-logfiles, last recovery-log and an obligatory and empty lost+found directory. So we have got another 114 MB of space that can now be used as fast swap space for the kernel.
Also, the /system partition normally is not fully used - depending on the rom, a more or less amount of this area is free and unused.
As these areas all are internal memory, these swaps are faster, than a swap area on the sdcard!
TRY IT – YOU WILL BE CONVINCED AT ONCE!
If you are afraid of too many read/write requests to /cache, /data, /system, which may harm your eMMC memory of your phone, then don’t read further – we are not afraid, because there are also a lot of read/write requests to the /data partition as well and this is in Android “by design”. Furthermore there are devices, that have a preconfigured eMMC-swap space "by design", as for exaple the HTC One V.
Installation
Just download the Aroma-Installer, copy it to your sdcard, reboot into recovery and flash it as you would do with a new rom. It also has an option for removing, if you don’t like it – but we think, that this option is useless …
To determine the right size for the swap files, refer to the point “How can I check the size of the partitions” of the Hints/FAQs section below.
Advantages / Disadvantages
Disadvantages of a swap file on your sdcard:
A sdcard is always slower than internal memory
You may NEVER unmount the sdcard or connect your phone to your computer, because you then just kill your swap file – it is the same as pulling out the Ram of your running computer!
Disadvantages of a swap partition on your sdcard a.k.a. HARD SWAP:
A sdcard is always slower than internal memory
You will need a separate partition on your sdcard
You can connect the sdcard to your computer, but you cannot unmount and remove it without powering off your phone – you would kill your swap space immediately!
Disadvantages of a swap file in RAM - a.k.a. ZRAM:
This reduces the already low RAM memory
Leads to many low memory problems, like sense restarts and lags
Advantages of 98swap_ compared to the methods above:
It uses internal memory – so it is fast!
This memory is not available to the user (/cache and /system) – so it does not decrease any space given to the user
It does not use your sdcard in any way – so feel free to unmount and remove your sdcard whenever you like – also without powering off your phone!
Disadvantages of 98swap_cache
None - you name it!

★Can I use Turbo Boost?
Yes, you can! I have tested it with ViperXL JB 4.20 , & KickDroidXL v4.0.0, works with ElementalX v8.3.2
★How can I check the size and free space of the cache , data and system partition ?
Open a Terminal Program.
- type
Code:
df /cache
or/and
df /data
or/and
df /system
to get the state of the cache , data and system partition .
You will see some ting like this:-
http://s20.postimg.org/6ui8zt171/Df_cache.jpg
Or
- open Android System Info (available in Google Play), switch to system tab and open the “Memory” section. The first point “Download Cache Max” will show you the size of the partition and the available free space.
★How can I check my current Swap Space(s) and Size(s) ?
Open a Terminal Program.
- type
Code:
cat /proc/swaps
to get the state of all swap spaces separately .
You will see something like this:-
http://s20.postimg.org/yj4w7bo7h/cat_proc_swaps.jpg
Or
- type
Code:
free -m
to get total information of all swap spaces.
You will see some ting like this:-
http://s20.postimg.org/ghlr9iu6l/free_m.jpg
★How can I uninstall Turbo Boost?
Simple – just reboot into recovery and flash Harbir’s Aroma-Installer again – it has an option to remove the script-
★How can I Disable/Enable the Swap file ?
Just flash the script again with the fantastic Aroma installer from Harbir.
or (for EXPERTS only)
For temporarily disabling/enable it:
- open a Terminal program.
- Disable/Off:
Code:
su
swapoff /cache/swap/swap.img
or/and
swapoff /data/swap/swap.img
or/and
swapoff /system/swap/swap.img
- Enable/On:
Code:
su
swapon /cache/swap/swap.img
or/and
swapon /data/swap/swap.img
or/and
swapon /system/swap/swap.img
(it will also be enabled again by the script by a reboot)
For disabling the cache beyond a reboot:
- Go to the init.d directory and
- Disable the script by
Code:
cd /etc/init.d
chmod 644 98swap_cache_v300
or/and
chmod 644 98swap_data_v300
or/and
chmod 644 98swap_system_v300
- Enable the script by
Code:
chmod 755 98swap_cache_v300
or/and
chmod 755 98swap_data_v300
or/and
chmod 755 98swap_system_v300
★How can I change the size of my Swap file ?
Just flash the script again with the fantastic Aroma installer from Harbir.
★Can I use 98swap_cache together with the ZRAM option of my Kernel / ROM?
THAT WILL BE QUITE USELESS AS OUR MAIN PURPOSE IS TO FREE UP SOME MORE RAM.
But of course you can use it with ZRAM enabled. In this case you can reduce the ZRAM option to e.g. 50-75 MB and use 50-75 MB for 98swap_cache.
The command
Code:
cat /proc/swaps
(see above) will then display two swaps.
★Triple or Dual or Single Swap - which one is better and what is the difference?
We started to use /cache as swap space, because this space is not used on most phones. But on /cache you have only about 110 MB free space, even less with CM10.1 ROMs, and that might be insufficient for heavy usage. Our experience is, that e.g. with a Sense ROM, the phone needs about 150 MB of swap space. Now, this new version gives you the possibility to create two swaps, e.g. 100 MB in /cache and another one with 75 MB in /data and also gives you the possibility to create three swaps, e.g. 50 MB in /cache , another one with 75 MB in /data and 50 MB in /system . This is also sufficient for heavy usage.
★Is there a difference in performance to have one or two swaps or three swaps?
No. Two swaps will just give you the advantage to make better use of your free memory space, depending on your ROM.
★Which size shall I plan for the Swap Space?
We have very good experiences with Swap Spaces in total of 175 MB. This can now be made by two Swaps, e.g. 100 MB in /cache and 75 MB in /data or can now be made by three Swaps, e.g. 50 MB in /cache , 75 MB in /data and 50 MB in /system.
★My phone runs fast with Turbo Boost, but gets laggy again after a few days - what can I do?
This happens, when the phone needs all of the configured Swap Space - so the size is not sufficient in comparison to your usage of the phone. Just raise your Swap Space or configure a second Swap Space on a different partition - the new Aroma even supports Dual Swaps as well as Triple Swap.
support your device
to do this, we will need your help. At fist you have to install the script manually to confirm that it's working. In the second step we will need a few details of your phones to modify the aroma setup. Let's start with the first step:
Installation instructions:
Download the aroma
extract the file 98swap_cache_v300 from the folder \swap\cache\50\etc\init.d in the aroma
what to do:
Enter es-explorer and:
Go to es-explorer settings/root settings/check (root explorer ,up to root and mount file as writable).
Copy the script 98swap_cache_v300 to /system/etc/init.d
don't reboot!
Open a terminal session and get superuser rights with the command: Su
command: Cd /system/etc/init.d (now you are in the init.d folder, where the script is)
command: Chmod 775 98swap_cache_v300 (now the script has execution rights)
reboot
now:
Open a terminal session and get superuser rights with the command: Su
command: Cat /proc/swaps (shall show the new swap file /cache/swap/swap.img)
with es-explorer navigate to /data/swap and look into the log file swap_cache.log
please, sent delta-roh the logfile swap_cache.log via pm!.
If it's working, we have to do the second step:
The second step is, to include your device in the aroma; we need the internal device name and the mount point of the file systems. Do the following:
Open a terminal session
get a superuser shell with the command: Su
now the command:getprop ro.product.device
(that's the internal device name - i will need that name exactly)
now the command: Mount
(we need the mount points from /cache and /data and /system; if you do not find them, just use the command "mount > file" - this will write all output to "file" - then send me "file")
done!!!
If you have questions - feel free ...

After testing it for more than 7hrs i can say that Prefomance has improved without any bugs but facing a slightly higher battery drain while using triple swap.

With this mod it gives your device a way to use swap memory when Ram is running low.. so with swap being on the emmc ( system, data, and cache ) the phone is constantly r/w so of course there will be slight decrease in battery... I could release a whole new mod to counteract the effect of battery drain, but then I'd be giving away to much of KickDroidXL Newest features.

Okay your having problems flashing in recovery? What recovery ? (TWRP, cmw, or phills ) also in recovery make sure system is mounted in mount section if so , choose reboot recovery and try flashing..... I use official twrp 2.6.3.0 I believe and when I've ran into that issue I just force reboot but upon boot I enter it in hboot and go to recovery that way and it works for me

Custom MTD Partitions
This is an implimentaion of lbcoder's Custom partition layouts
be sure to checkout that thread for the full history
What does it do?
Well, basically Custom MTD Partitions resizes your MTD partitions
for instance this is a CM6.1RC1, ( heavily customised )
Code:
Filesystem Size Used Available Use% Mounted on
/dev/block/mtdblock3 73.0M 72.8M 236.0K 100% /system
/dev/block/mtdblock5 134.8M 107.2M 27.6M 80% /data
/dev/block/loop0 896.0K 896.0K 0 100% /system/lib/modules
/dev/block/loop1 4.0M 4.0M 0 100% /system/xbin
/dev/block/mmcblk0p2 457.4M 201.8M 231.1M 47% /sd-ext
/dev/block/mmcblk0p2 457.4M 201.8M 231.1M 47% /cache
/dev/block/mtdblock4 2.0M 776.0K 1.2M 38% /dev/cache
most of my Apps are on sd-ext, dalvik-cache is on data
/dev/cache is where the real cache partition is mounted, /cache is actually a bind mount from /sd-ext/cache
Applicable to..
Probably any device that uses the same kind of nand as the G1 MT3G ( msm_nand )
The intial scripts are geared towards G1 / MT3G. however I have 'rewritten' much of the script for v1.5 , it now reads the partition table in dmesg, so it _should_ be universal **
v1.5.3 confirmed to work on heroc
v1.5.6 confirmed to work on bravo + bravoc ( with S-OFF )
unsure if it will work with your device? checkout the source on github ( or ask your favourite dev to take a look )
The 'Tech' in Breif
This method is beautifully simple...
When booting we give the kernel the mtd partition table we want to use..
Thats it
In practice we need to do this when booting to recovery, and booting the rom.
below are files to make this as simple flashing a rom.
Credits :-
Lbcoder - for coming up with the idea
Skraw ( CM forums ) - for getting lbcoder interested
Koush - for AnyKernel
Cyanogen & Co - for giving us all such great ROMs to play with
Amon_RA and Koush - for giving us something to patch
Techjosh - for fixing the patchers for use with Rogers (EBi1)
Mblaster - for pointing out my nasty habit of using -r zip flag at the end of command ( breaks compatibility with older zip versions, fixed in AutoPatcher v1.5 )
Safety First
This method is safe, however it is not without risk
Two things could potentially go wrong
Recovery flash corrupt
This is extremely unlikely, and tbh could happen anytime you flash recovery
If in the very unlikely event that you find you can't reboot to recovery you have three options
re-flash recovery via fastboot ( the preferred option )
re-flash recovery via ROM ( not a great option with cm5.0.x/cm6 )
Do the whole root thing all over again ( no one wants to do that )
system, cache , data partition unmountable - corrupt
Under the right ( or wrong ) circumstances it is possible to get 'junk' files stuck in system ( or cache,data ), and in such away that recovery can not delete them, more serious corruption can render the partitions unmountable.
It is actually quite straight forward to fix this, but it does require fastboot
Code:
fastboot erase system -w
Clockwork Recovery 2.0.2.0 and later has erase_image binary, if you can adb shell in then
Code:
for i in system cache userdata;do erase_image $i;done
and reboot
I would advise you seek out how to 'fastboot', which tbh is a good thing to have regardless of using this 'hack' as it can get you out of so much trouble
*NB* don't use a patched recovery to flash SPL or RADIO ( you should avoid using recovery to flash these anyway, feel free to ask for current advice on spl / radio flashing )
Prevention is better than cure
I have only managed to corrupt partitions when switching partition layouts while having files on cache or data, for example going from System 67.5 Cache 67.5 to System 90 cache 5 with
cache approx 80% 'used'...
I have not been able to repeat this if I wipe Cache before rebooting,
therefore I advise that you wipe both cache and data * after patching recovery ( and rebooting )
* along with system if you are using clockwork
OK, now lets patch recovery and a ROM
Install Instuctions
It really is quite simple
download FR-recovery-v1.5.6-CustomMTD_S.zip and FR-boot-v1.5.6-CustomMTD_S.zip
create mtdpartmap.txt and put on /sdcard/ see configuration *
reboot to recovery
nandbackup
wipe cache + data
flash FR-recovery-v1.5.6-CustomMTD_S.zip
reboot to recovery ( reboot and hold Home )
Either : -
Nandrestore
Flash ROM + extras
flash FR-boot-v1.5.6-CustomMTD_S.zip
reboot
* configuration
The script in the recovery patcher checks for /sdcard/mtdpartmap.txt and reads that to override the default sizes.
e.g. for system 90mb and cache 2mb
NB make sure you mount sdcard first, else you won't write to sdcard/mtdpartmap.txt !
Code:
echo "mtd 90 2" > /sdcard/mtdpartmap.txt
data would be 117.8mb ( 116.7 useable )
e.g. for system 55mb and cache 2mb ( Purhaps a nice 'sugar free' Donut )
Code:
echo "mtd 55 2" > /sdcard/mtdpartmap.txt
data would be 152.8mb ( 151.7 useable )
NB, above data sizes are for G1s, MT3Gs should add ~78mb
All In One Patch runner ( New to v1.5.3 )
new option to run the All In One Patch script ( versions 1.3.6 and higher )
the format is
Code:
aio <option1> <option2> <option3>...
e.g.
Code:
aio swap remount shabang lwp
By default it will install the sd-ext mount ( option sdext )
so a line just reading aio will be fine
Note: the patch must be on the root of the sdcard, and its file name must start with "fr-patch" and end with ".txt"
if you have several versions the newest ( as per files datetime stamp ) will be used
Faking your SPL
If your using an SPL that is not officially supported by your ROM and that ROM checks your SPL you can 'patch' to fake it.
Code:
echo "spl 1.33.2005" >> /sdcard/mtdpartmap.txt
note that we are using ">>" here, this is to append to the file ( ">" would overwrite it )
you can by all means use any text editor you like, the script will automatically convert to unix format
NOTE : you are dodging the checks the ROM dev put in place, do not complain to them if this doesn't workout for you
in post 2 I have some 'CM6' Kernels I compiled for (1)0.95.xxxx SPLs
but I will only likely do these for RCs and Finals ( and there maybe a delay ).
In that post I point you towards the 'SafeSPL' ( 1.33.2003 ) this SPL is compatible with the current CM6 kernels ( so no need to wait for me or someone else to compile with bluetooth as modules ), but 1.33.2003 is not 'officially' supported ( its stock at 67.5mb system ) so you need to Fake your SPL ( say 1.33.2005 ) and resize to 90mb system ( or whatever you feel is optimum )

ROM Zip Patcher for Devs
To make life even simpler for end users it is possible to integrate the 'patch' within a ROM
AutoMTD_partitionPatcher_v1.5.6.zip
currently Linux only,
within the zip is a tarball, untar that.
get that directory into your PATH, ( or just cd into it )
and then execute
Code:
PatchUpdateScript.sh <zip file to patch>
it will then
create a temp directory ( in your current directory )
copy your zip to it
extract required files
patch update(r)-script
zip and sign.
It simply saves the user from flashing the boot patch after flashing your ROM
The Future....
lbcoder has already suggested ways in which we can implement this 'on the fly'
so for instance it would be possible for a ROM , to instruct recovery what MTD partition layout is required, reload mtd kernel modules, and then flash ROM + boot.img
for those with huge partitions
Hey, you could go all silly and dual boot between ROMs ..
Anyway, enjoy and feel free to modify/improve on these
Changelog
v1-5-6 : 2010-10-28
Calculate userdata size, greatly improves compatibility
Added a version to patch a boot.img ( boot-rpp ) with run-parts
didn't want to , but some are using roms which don't have run-parts, so the 06BindCache script wasn't running
Added a remove version ( remove )
flashing this will return the recovery to SPL's layout
I may well integrate that better, so you don't need a separate zip
AutoMTD_partitionPatcher can convert a recovery.img to a AutoMTD flashable zip
PatchUpdateScript.sh <full path to>/recovery.img
boot patcher is much cleaner, it just uses the cmdline of the running recovery
removed the default 90 2 sizing, you *must* set your own size in mtdpartmap.txt
v1-5-4/5
added stuff
removed stuff
moved stuff
see v1-5-6
v1-5-3 : 2010-08-13
This should be last version we need
greater compatibility with none dreams/sapphires
option to launch All in One Patcher
v1-5-2 : 2010-08-0
Bug fixes
recovery was getting written to boot ( flash_image <partition> is now a variable )
typo in env variable was causing cache and data calculations to fail
AutoMTD now prints version number ( when flashing patched Zip )
tided up system "0x" 'fudge' ( to be compatible with trout/sapphire fall back )
removes temp files from memory when done
v1-5-1 : 2010-08-06
Bug fixes, had an extra '0x' on the system start + functions had wrong env var for the location of dmesg derived partition map
v1-5 : 2010-08-06
Version numbers brought into sync
Zipe Filename - 'reordered' ( easier to see version numbers in CWR )
AutoMTD Patcher - changes as per boot Patcher + zip recursion fix ( my bad habit, thanks go to mblaster for pointing this out )
Boot Patcher - cleaned up cache bind mount
Now supports leagcy /system/sd mount point
[*]supports ROM Manager ( real cache partition mounted on /dev/cache, recovery dir symlinked from 'fake' to 'real' cache )
Recovery Patcher - can 'fake' your SPL ( see configuration )
Recovery Patcher - creates more noise ( advise wipe and reboot )
Single Patcher script ( so I don't have make the same changes to three different files that essentially do the same job )
No longer 'Hardcoded' to 32[a/b] Partition Layout ( figures out SPL layout via dmesg ) **
uses original boot/recovery img's base configuration ( i.e. EBi0 and EBi1 compatible )
=< v1.4
Recovery Patcher v1.3, added SPL faker
Boot Patcher v1.2, fixed oversite where boot.img was not 'dumped'
Recovery Patcher v1.1 initial
Boot Patcher v1.1 ( was a fail, it didn't patch boot.img on CM roms as the tmp boot.img was deleted, my fault for just using the AutoMTD Patcher's script ( which runs before the tmp boot.img is deleted )
Boot Patcher v1 initial
Todo
- 2010-08-13 redundent ( launching AIO script ) - I might add some stuff to cm5/6's backup routine via the Auto patcher, things like the "All in One" installed scripts: 05mountsd and remount
windows compatible AutoMTD script ( meh, I hate batch scripts )
- 2010-08-13 DONE - thinking of adding a config option to launch the "all in one" script, but have to make that recovery compatible first

Custom MTD FAQ
FAQ
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Q my SPL starts with 0 or 10, and I want to try CM5.0.8 or/and CM6. DO I need to do anything extra?[/b]
A yeap, it seems the newer kernels are just a bit too big for x0.95.x00x SPLs, you can get round it with the below kernels. And to flash CM6 you need to 'fake' your SPL ( see configuration in OP ) or edit the updater-script. faking is easier.
However, I would recommend the 1.33.2003 SPL ( you still need to fake your SPL, but you won't need the 'special' kernels )

I have compiled a kernel, which I hope is NoneDanger compatible
the source is simply CyanogenMod's github, I have taken the config from cm6rc1, and simply changed the bluetooth to modules
this approach has worked in the past
It is pre-patched with AutoMTD, so just flash cm6rc1, then flash this

*NB* don't use a patched recovery to flash SPL or RADIO ( you should avoid using recovery to flash these anyway, feel free to ask for current advice on spl / radio flashing )
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Q do I need to flash both of the files each time I install a new rom?
A No, you only need to flash the recovery patcher once, unless you want to resize or you install a new recovery.
the boot patcher *must* be flashed after you have installed a new ROM or Kernel update
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Q my cache looks odd in df, I see two and its the same size as data or sd-ext, is something wrong?
A everything is fine, since we shrunk cache its no good for things like the Market, so a script is installed to 'bind mount' cache with /sd-ext/cache or data if sd-ext is not mounted.
it actually turns out that /cache is not actually used in CM6, so I might adapt the script a little in a future release.
EDIT: as of version 1.5 the cache bind mount script mount 'real cache' separately, which should reduce confusion
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Q When I tell ROM Manger to do something in recovery, it just reboots to recovery and does nothing. it used to do the action but not since I installed CustomMTD
A yeah, nearly forgot about that, I was going to fix it last week, basically ROM Manger writes commands to /cache, but its writing it to our bind mount so.. when recovery boots it doesn't see the commands.
In all honesty that one hasn't been pointed out to me yet, but yeah I can fix it..
EDIT: as of version 1.5 the cache bind mount is compatible with ROM Manager

errm, tbh I'm not all that clued up on it yet
looks very promising
So, will i need to change the values everytime i flash a different rom? or can i just set them to a large size and everything will work?

most roms have a target of 90mb system ( DangerSPL )
so 90 2 config will basically give you an extra 28mb on data than you would have with stock DangerSPL MTD map
so yeah
90 2 is a good all rounder

is it okay if I make system 70mb?
The rom im using is only using 66 out of 90, i want more space for data instead. I remember you said something about it being a miltiple of 128K.
With this, could Devs stop skimping on stuff like wallpapers and ringtones or additional apps, and surpass the 90MB danger spl mark? It would seem so. Also, I do not make roms so I do not know how it works but if there is compression or lower quality stuff they would now be able to use up as much space as wanted correct?

yeap, should be fine
personally I would be tempted to use clockwork, since you can erase system ( part of partition options )
.img files can be found here
http://www.koushikdutta.com/2010/02/clockwork-recovery-image.html
I don't recommend flashing via ROM Manager with CM5 or CM6
fastboot it over, or flash via recovery
I may be a little over cautious recommending a full wipe, but I have never had problems when system, cache and data are clean.
if you are 'growing' system make sure cache and data are clean
if your 'shrinking' make sure system is clean ( so 'hangovers don't mess up /cache or data )

Hi firerat,
you mentioned once before something about market data on the cahe... or something so downloads would be ok if a certain partition was big enough?....something like that... I am having a prob that might be related since it started when I tried to change from default to system 80 5 for data. now I cant sign in to google and after flashing gaaps there is no market? everything else in the gaaps zip is there...? It could be google i know but i remembered you saying that somewhere.

I very much doubt it is related in anyway
/cache is where the market downloads apks to prior to install
it should be bind mounted to /sd-ext/cache or /data/cache if sd-ext is not mounted
your missing Market is related to something else

When I download stuff with dolphin HD it goes to /sdcard/download

the cache bind mount is
added a few extra comments to make it easier to follow
/system/etc/init.d/06BindCache
Code:

if [ "`awk '/\/cache/' /proc/mounts |sed -n '$='`" -gt "1" ];
then
echo "cache already bind mounted"
echo `awk '/\/cache/' /proc/mounts`
exit

# check if /sd-ext mounted, if yes then bind to /sd-ext/cache, if not /data/cache
if [ "`grep -q sd-ext /proc/mounts;echo $?`" = "0" ];
then
CacheDir=/sd-ext/cache
else
CacheDir=/data/cache
fi
# check we have something to bind mount, and create if not
if [ ! -d $CacheDir ];
then
install -m 771 -o 1000 -g 2001 -d $CacheDir
fi
mount -o bind $CacheDir /cache
# check dalvik-cache exists ( this is really for magics )
# so they don't end up in bootloop because dex files can not be created
if [ ! -d $CacheDir/dalvik-cache ];
then
install -m 771 -o 1000 -g 1000 -d $CacheDir/dalvik-cache

actually, errm yeah it is d/l to /sdcard/downloads

Froyo has been nice so far
but you may run into issues
for one the updater-script is actively 'kicking' NoneDanger
you can just remove the getprop checks
I have had problems booting cm5.0.8's kernel, I did get round it by compiling a new one from cm github,
I
'm not sure is cm6's kernel has the same issue
it does seem SPL related, I flashed Danger and it was fine, I plan to go back to NoneDanger and confirm it still doesn't work.
but figured that while I was on Danger I might as well put this (Custom MTD) through its paces with a DangerSPL

double edit: i get the same error for any rom i try to flash when i look at the logcat. the only difference is cm's latest nightly build rebooted on the g1, super e freezes at the g1 screen...ima try to modify the .txt to go back to the stock layout so i can nandroid my cachehacked cm5.08 back if not...idk what to do..

Odd, but at leasat the kernel is booting, I wasn't getting anywhere with cm5.0.8
It could be a general error
Which build are you using
I'm on a nightly, but I know Defcon works
If its still not working, try the older v1 version of boot patcher in lbcoders thread
I did change boot v1.1 to the script I use in the automtd one
I'm on the nightly 0704 (944 I think ) btw

**EDIT ... took market down til I can fix.
i would recommend doin a nand backup before pushing this. i pushed it 4 times to my phone. 3 of those times it worked fine. the one time it didnt work i have no idea why as i didnt do anything different.
to push this go to adb shell and type :
mount -o rm,remount -t yaffs2 /dev/block/mtdblock3 /system
now back put of shell and put the Vending.apk into the push folder. now you will type :
cd push
adb push HtcDialer.apk /system/app
....................now your done.
A majority of this theme is from papasmurfs RedDawn with a few tweaks of my own and some random icons i have ran across place to place. i cant take the credit for this other than i test each thing and make sure it functions and get it to work for a stock rom (like this one) and simply put it together.
BTW: no FC's for contacts or contact widgets on this one. thats what took so long lol.... only issue i know of is setting up speed dial. other than that, all of it works. been using it a few days now. If you run into anything let me know and i will see what i can come up with. - Leadfoot

***How to check the MD5 Hash***
Windows (and mac) users:
1. download Hashtag, a free md5 file hash check utility from here: http://beeblebrox.org/hashtab/
2. After downloading and installing, just right click on any file. On Windows, select properties and you will see a new "File Hashes" tab. On Mac select "File Hashes" (on 10.5 the "File Hashes" menu item will be found under the "More" submenu). This is will start HashTab providing more or less the same view that you see on Windows. This File Hashes window displays all the hashes for the file.
3. Check the hash to make sure it's the same big jumble of numbers and letters as the hash above. If it is not the same, the download is bad and you should redownload the file.
Linux users:
1. go into your linux terminal or shell (not the adb shell)
2. navigate to the folder that contains the rom (mine is in downloads, so you would type 'cd Downloads')
3. for my rom, type 'md5sum SouthPawV1.5Final.zip
4. the output should look as shown:
Code:
OUTPUT_ZIP$ md5sum SouthPawV1.5Final.zip
F0D9E1F279FA7B0FA8636616499CD0C8 SouthPawV2.0-Beta.zip
[email protected]:~/Desktop/kitchen/OUTPUT_ZIP$
Installation:
***for newbies, see the second post under "How to root/maximizing my rom experience"***
1. Nandroid
2. Wipe
3. Flash
4. After install see configuring a2sd for more memory on the phone and JIT/Swap configuration in 2nd post! (and possibly a faster phone if you have a class 4 or higher memory card)
Bloated apps can be re-downloaded here: http://www.mediafire.com/?7ektxbiq0h65ftr

*You do not need to be flashing this file if it's already updated because that is the one file that CAN brick your phone if it's corrupted. ALSO if you ARE downloading this file, CHECK THE MD5 hash! Instructions above. It could mean the difference between a happy updated phone and a BRICKED phone.*
***How to root and Maximizing your rom experiance***
I hold no responsibility for any actions resulting from these links and/or this post.
How to root your CS Hero. Read first post, it describes everything
http://forum.xda-developers.com/showthread.php?t=581869
***How to flash any rom***
After rooting your phone to install any rom (not just mine)
1. backup everything if you have not already done so, you will lose EVERYTHING on the phone itself, (except for everything on the memory card)
1a. download my rom or another rom (as long as it's for your phone and radio)
1b. place the rom in the root directory (or the main directory rather) of your sdcard.
2. Turn the phone off
3. While holding the home button, press the power button until you see the recovery mode menu. (I am using clockwork mod 2.5.0.1 so depending on your recovery YMMV. You should use the instructions for your specific recovery system. They are using Darch's version of AmonRA's recovery, This is covered in the first post on that link as well.)
If you are using Clockwork Mod, you can use these instructions:
4. go to wipe data/factory reset and go to yes to start the wipe.
5. scroll down to wipe cache partition, and confirm
6. scroll down to advanced and wipe dalvik cache.
7. After that, scroll down to "install zip from sdcard"
8. select choose zip from sdcard
9. select the rom file from the memory card (mine will be SouthPAW!1.5-Final) and confirm to flash it.
10. Once the flash is done, reboot the phone. It's going to take between 5 and 10 minutes to boot the first time so be patient, and don't mess with it. After you get in you are golden, and nothing else is to be done. You have made it..
***how to maximize your battery performance***
This rom comes with an overclocked kernel that automatically sets itself to maximize battery life. But there are things you can set to make the kernel do what you want
***Kernel parameters***
You don't have to use any overclocking software to set the speed of the processor with this kernel Here is the parameters:
Syntax: echo "(speed in hz)" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
Example:
echo "768000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

Sets the cpu to max out at 768mhz
echo "710000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

If your gps quit working for some reason do this:

I haven't found full explanation on ALL the governors, but I guess it's a no brainer, however here is the info I pulled off of the kernel thread:
(For Interactive governor)
This governor is designed for latency sensitive workloads, UI interaction for
example.
Advantages:
+ significantly more responsive to ramp cpu up when required (UI interaction)
+ more consistent ramping, existing governors do their cpu load sampling in a
workqueue context, the 'interactive' governor does this in a timer context, which
gives more consistent cpu load sampling.
+ higher priority for cpu frequency increase, rt_workqueue is used for scaling
up, giving the remaining tasks the cpu performance benefit, unlike existing
governors which schedule rampup work to occur after your performance starved
tasks have completed.
Existing governors sample cpu load at a particular rate, typically
every X ms. Which can lead to under powering UI threads when the user has
interacted with an idle system until the next sample period happns.
The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down
to.
There is only one tuneable for this governor:
/sys/devices/system/cpu/cpufreq/interactive/min_sample_rate:
The minimum ammount of time to spend at the current frequency before
ramping down. This is to ensure that the governor has seen enough
historic cpu load data to determine the appropriate workload.
Default is 5000 uS.

***how to partition for apps2sd for Amon Ra's Recovery and Cyanogen's Clockwork Mod Recovery***
Instruction Source: http://www.villainrom.co.uk/wiki/index.php?title=Apps2SD#Normal_Installation
How to Setup SD card partitions from AmonRa's Recovery:
1. backup your stuff on your memory card. It is very possible that this will erase everything on your memory card.
2. Shut down the phone
3. Press and hold the home button while pressing the power button. Keep holding the home button until you get to the recovery menu.
4. Select Partition sdcard
5. Select Partition SD
6. Set the following partition sizes using the trackball or volume buttons:
-ext: 512MB - recommended. You will feel like you can install everything from the market.
-swap: none -not a prerequisite but recommended. use at least 30mb.
-fat: remaining
7. Reboot the phone. It may take a little while for boot to finish on this boot only.
How to Setup SD card partitions from Clockworkmod Recovery:
***Do not partition with Clockwork mod. There are some issues that I have read that will mess up your install***
There are alternative methods for this, but it's just easier to use Amon_Ra's image for this.
***How to setup a2sd/Swap/JIT***
A2SD is already enabled by default on this rom. However Swap and dalvik to sd is not!
To get swap working (if you made a swap partition on your sd card)
1. get to adb
2. adb remount
3. adb shell
4. a2sd reswap
To move Dalvik cache to sd -
5. a2sd cachesd
VOILA! 149MB free on the phone! *w00t*
Also there is more config you could do here. You can enable JIT *dunno if it works, so add at your own risk*
***More info for a2sd configuration***
Code:
Standard Apps2SD Commands:
--------------------------------------------------
reinstall
Moves free and paid apps to the ext2/ext3/ext4 partition on your secure digital card. Removes the No A2SD flag file.
This is used if you have already executed an a2sd remove command. Otherwise, this part is automatically performed when Apps2SD is started.
File removed: /data/.noa2sd
remove
Moves free and paid apps to the internal phone storage. Creates the No A2SD flag file.
File created: /data/.noa2sd
Swap Partition Commands:
--------------------------------------------------
reswap
Removes the No Swap flag. Allows A2SD to activate the swap partition.
This is used if you have already executed an a2sd noswap command. Otherwise, this part is automatically performed when Apps2SD is started. Note: This command has no effect on roms where the swap space is not built into the kernel.
File removed: /data/.noswap
noswap
Creates the No Swap flag. Prevents A2SD from activating the swap partition. Note: This command has no effect on roms where the swap space is not built into the kernel.
File created: /data/.noswap
swappyxx
Sets the swappiness setting for the swap file. xx sets the swappiness percentage used. (i.e. to set swappiness to 30%, type a2sd swappy30.
Dalvik Cache Commands:
--------------------------------------------------
cachesd
Moves Dalvik cache files to the ext2/ext3/ext4 partition on your secure digital card. Creates Dalvik Cache to SD flag.
Caution: If your phone fails to mount the ext2/ext3/ext4 partition and your dalvik-cache is pointed to the SD card, you will likely end up in a boot loop. Execute a2sd nocache from adb shell to rectify the issue.
File created: /data/.dalvikcacahe
File removed: /data/.dcpartition
cachesdreset
Same as cachesd above, but erases the contents of the dalvik-cache after move. This performs both the a2sd cachesd and a2sd resetcache all in one command.
File removed: /data/.dcpartition
cachepart
Moves Dalvik cache files to the /cache partition in your phone. Creates Dalvik Cache to Cache Partition flag.
Caution: Some phones do not have enough space to put the dalvik-cache on the cache partition. Also, some roms that have SenseUI installed may not work well with the dalvik-cache on the cache partition (although this issue appears to be fixed starting with Darktremor 2.7.5.1). If you experience issues such as force closes, try moving the dalvik-cache to the SD card (a2sd cachesd) or internal storage (a2sd nocache) instead.
File created: /data/.dcpartition
File removed: /data/.dalvikcache
cachepartreset
Same as cachepart above, but erases the contents of the dalvik-cache after move. This performs both the a2sd cachepart and a2sd resetcache all in one command.
File removed: /data/.dalvikcache
nocache
Moves Dalvik cache files to the internal phone storage. Removes all Dalvik Cache flags.
File removed: /data/.dcpartition, /data/.dalvikcache
nocachereset
Same as nocache above, but erases the contents of the dalvik-cache after move. This performs both the a2sd nocache and a2sd resetcache all in one command.
File removed: /data/.dcpartition. /data/.dalvikcache
resetcache
Clears the dalvik cache and restarts phone.
Apps2SD Diagnostic Commands:
--------------------------------------------------
check
Performs a symlink and flag file check on your setup. Outputs a report that shows you if
there are issues with your Apps2SD setup.
repair
Performs a repair of all symlinks based on flag file activation.
diskspace
Shows disk space statistics for the ext partition.
sysinfo
Displays information about your phone, partitions, swap, and more.
Also writes a dump file that has an entire profile of your phone. This is for troubleshooting only.
File Created: /data/dtsysdump.txt
swapspace
Shows swap space statistics for all swap space active on the phone. Note: This command has no effect on roms where the swap space is not built into the kernel.
ZipAlign Commands:
--------------------------------------------------
align
Performs a one-time zipalign on all APK files in /data/app and /data/app-private.
zipalign
Allows ZipAlign to execute during the boot process. Creates the ZipAlign flag file.
File Created: /data/.zipalign
nozipalign
Prevents ZipAlign from executing during the boot process. Removes the ZipAlign flag file.
File Removed: /data/.zipalign
Dalvik Setting Commands:
--------------------------------------------------
jit
Installs DalvikVM JIT.
WARNING: Do not run this command if your phone has NAND protection active.
nojit
Removes DalvikVM JIT.
WARNING: Do not run this command if your phone has NAND protection active.
defaultheap
Resets the Dalvik heap size to the default heap size.
File Removed: /data/.smallheap, /data/.largeheap, /data/.jumboheap
heapsizexx
Sets the dalvik heap size to xx. For example, to set the dalvik cache to 24mb, type a2sd heapsize24. To reset back to default, type a2sd heapsize0 (that's a zero, not the letter "o")

***How to push an apk file using adb***
*Of course you have to have a rooted phone to do this, if not check the ***how to root*** section first before getting this far.*
This tutorial is going to use the linked deleted files zip from the link in the first post.
1. Download the Android SDK for your appropriate Operating System from here: http://developer.android.com/sdk/index.html
2. Once downloaded, be sure to download the deleted files zip from the link in the first post.
3. Extract the Android SDK file to an easily findable folder
4. Extract the deleted files from the zip file, and copy the apk file you choose to the AndroidSdk\tools folder. For reference I will be using the Dialer.apk file in this tutorial (not included in the zip).
5. connect phone to computer and select "charge only" from the menu.
(*for windows Vista/7/XP*)
*prerequisite* - you must have the adb drivers installed to do this in windows.
6. Click Start, go to > All Programs > Accessories, and from there, right click 'command' (something like that), and click 'open as administrator' (XP users do not have to do this, just go to Start > Run, type cmd, and press enter)
7 .navigate to the android tools folder you put the apk file in (the command to change directories is 'cd' and then a space, and the name of the next folder, so to navigate to the 'android' folder, you would type 'cd android', and then you can use 'dir' to see the next directories till you get to the right folder.
8. type 'adb remount'. This is going to start the adb system, and then remount the phone in root mode.
9. to check to see if your phone is mounted and everything is kosher, type 'adb devices' and it should show something on the bottom that should be your device or serial of the device. If it says ??????????? then it's not working.
10. type 'adb push HtcDialer.apk /system/app'
11. DRINK A BEER! You have pushed an apk to your phone! To check if it is installed, simply click the call button (or press phone on the rosie), go to settings and select speed dial. Then see if you can change/add a number to speed dial #2. This could possibly require a reboot to actually start the new version of the installed software but you should just be able to go ahead and use it
(*for Linux*)
6. Once you extract the android-sdk-linux_x86 folder, go to the terminal, and navigate to the android folder pretty much the same way as windows, except instead of using dir (ubuntu users can use it), use 'ls'
7. type 'sudo ./adb remount' and when asked, type the administrator password for the linux system. This is going to start the adb system, and then remount the phone in root mode.
8. To check to see if your phone is mounted, type 'sudo ./adb devices' this should show your device.
9. To do that actual push, type 'sudo ./adb push HtcDialer.apk /system/app'
10.

Hell yeah! Although the neighbors didn't appreciate me running around in the front yard naked! Hmmm.... Maybe I will try the backyard next time.
Good job. I'm glad somebody finally got a CSouth Rom on here.
If you need any assistance let me know.
Ok I go to filedropper site but all I get to download is an empty folder, 66.7kb????. Has the file name but no data, or am I completely missing the right link? Do I need to join to download? Thanks, would really like to try this ROM out.
I got the download, followed all steps, it says that the zip is bad. I deleted the old one, transferred a fresh one to card, same story. I'm downloading the zip again just to make sure it didn't corrupt while downloading.
Anyone else run into this problem?
zip flashed fine for me. Just booting up
Can this be used in other non-sprint heros?
Also, I was wondering if it is possible to have like a stripped / universal version for non-sprint heros and then install CS’s or other carrier’s stuff apart like DarchDroid did with his naked rom with Google ****s apart.
Thanks for sharing it!
I downloaded it from the link with no problem. I did the following:
1.downloaded the zip
2.transferred it to the SD Card
3.HBoot
4.Created Nandroid
5. Wiped everything
6. flashed in zip file
It works pretty good. I can't get my yahoo account to work. I also can't get the new widgets to download to the phone and work. They download and then I don't get them. Hmmmm....
Anybody know how to change pri version? Mine is 1. Something but my non rooted phone is 2.51_013
Even though I am on AT&T with a Magic and Captivate it is good to see some Cell South love around here. I will be using your rom to flash to as many friend's Heroes I know.
Bring on the Incredible, Milestone, and Galaxy S now C South!

That is odd. I have no idea tbh, but I'll try to check it out.
From here on out, any questions asked will be answered in the 2nd post on this thread.
***link is fixed!! Any issues please report!***
And yes this rom should work for non-cs users, but always take caution and do like you do with sprint roms, and it should be ok (and for those who didn't get voicemail notifications, this should support it)

To Mr. Danger, yes I will need some help soon. I want to branch this rom out to a couple of different versions. 1. With no apps (well junk apps anyways) with helix launcher and no sense, 2. With no junk apps with sense, and 3. Just the full montey (like now but with no issues)
@pound24. I just tried the link. It's working fine (from mediafire, not the old link, I removed that one)

This may be a dumb question, but you do need to root before applying this ROM, right?
Yes, the phone has to be rooted before loading anything except for the stock updates from the carriers.
[DEV] data2"XYZ" general filesystem discussion (Updated Dec 20 - Benchmarking)
I will rewrite this posting soon. As for now please check the scheduler Benchmark:
http://forum.xda-developers.com/showpost.php?p=9959265&postcount=257
================================================================
data2btrfs (this is DEV status so don't ask how to install - there is (little) linux expirience required)
Update about btrfs dec 15: Still testing btrfs and im REALLY amazed. Battery life has no difference to ext4 but performance is FAR better then ext4. I do still get lags in some cases (like fast! downloads) but this is simply a hardware issue which can not be addressed. Im using a class 2 sd only and i dont think that this can get ANY better. I think btrfs should run like HELL on a class 6+ card.
Update dec 14: Atm i'm using btrfs with "ssd_spread" (for ssd harddisk with older controllers. The controllers in SD should suck compared to some modern SSD so this will effect SD-Cards even more than "ssd" optimization (more info). And im amazed. It is even more smooth than nilfs (maybe less cpu) and so far the smoothest expirence i had with data2sd/data2ext. Even compared to EXT4 without journaling.
Why btrfs?
1. Btrfs is "copy-on-write" filesystem and i think that "copy-on-write" or logbased (like nilfs) will be the future.
2. Btrfs and nilfs are both better for "old" or "cheap" SSD-Drives because they are optimized for it. While this will decrease the performance of a modern SSD-Harddisk (since they are getting better and better in emulating a rotating device like a classic HD) it will INCREASE the general performance on ssd like an sd-card because their controllers is a lot worse than one of a state-of-the art SSD-Harddisk. So these optimization.
3. MeGoo (a linux made for smartphones) already has chosen it as default even though its still beta and i think they have some good reasons for this.
4. Btrfs has the same (and theoratically it should be even less - tiny) battery consumption. Other then nilfs wich had horrible battery (over 1%/h on its own even when phone was idle). Thats why i moved to btrfs from nilfs.
EDIT: Removed something really stupid xD
Safety concerns about data2btrfs
script: Considering the script i addressed ALL safety conserns that there are at present. This is based on the findings of the SGS devs and mounting directly on /data is even more save then cyanogen's app2sd+ (at least for the desire which unmounts /data - SGS doesn't). Only dalvik-cache is symlinked and a data corruption there is unimportant and can be helped by a simple wipe of the cache. So no concerns about this. (But note: the script is still "young" and there might be still errors - thats why i also don't provide a zip for ext4 yet)
btrfs is indeed still in an experimental state. But speaking FOR MYSELF ONLY (everyone should estimate this on its own) i don't have any concerns. The reasons are:
-experimental state is almost over and i doubt that there are any major bugs present.
-many Linux already use it and its default for MeGoo
-I have backups for all sensible data on my computer (like license keys - this can be lost if you backup already corrupted data with titanium/etc)
How to use it
(experienced linux users who know what they do ONLY)
- (recommended for ~ +20% speed) Delete your old ext partition create a new primary partition if it is not aligned yet. Gparted has a "align to mb" option wich makes alignement increadibly easy. Since 1024kb alignement is enough for sd there isn't anything else you need to care about.
- Make a btrfs partition with your favorite linux distribution (im still a ubuntu noob ) with btrfs utils.
- Make sure you flash a Rom that doesn't need sd-ext for installation (check the META-INF/../update-script for "copy_package XYZ SD-EXT:XYZ" - delete or format sd-ext there isn't a problem you will get an error (like on leedroid) on install but this doesn't matter)
-make sure you have Kernel with btrfs support (see below for this)
Kernels with btrfs support (SENSE ONLY for now)
-NeoPhyTe.x360 's (ext2, ext3, ext4, reiserfs, xfs, jfs, btrfs, nilfs2)
-Coutts99 Kernels (chose the btrfs-test-kernel ofc ;-) )
Known Issues
no btrfs support in recovery this means:
-no backup of the sd-ext partition (it isn't ext anymore ;-) )
-wont work with ROMs that need sd-ext for installation (some HD roms)
Thanks
- cyanogen who made app2sd+ in the first place.
- sibere and ownhere who started all the data2sd.
- supercurio and Unhelpful of SGS' Voodoolagfix (#Project-Voodoo on freenode) for their helpfull script tipps.
- Coutts99 and Neophyte for their Kernels.
- woti23 for all those test's in this thread.
- All devs of XDA in generall for all this nice stuff that is done here
Further Plans for the script
- Changing scheduler settings depending on results in the btrfs thread to get the last out of your SD while assuring safety (thanks woti23 for all the testing).
- Trying to add support to delete the ext partition and create it new with an 1024k alignement (~ +20% more speed)
- Mounting /app-cache to /cache or internal data partition (8 MB more RAM since its mounted on RAM)
- Changes for the mount options of the internal YAFFS2 Partition to optimize the speed of the "dalvik-cache" (have to look into YAFFS2 what can be done)
- Adding some lines of code to clear up any present symlinks on first boot to make it ROM upgrade compatible
- Adding e2fsck with check on every boot (script is quick edit of my script for btrfs - no e2fsck yet)
- Other changes based on the results in this or other threads about data2ext/data2sd
- Remove the errors i made ^^
---------------------------------------------------------------------------------------
Remark: i moved the data2ext4 script to my other script and set the dev tag again. I also added UBIFS discussion to the title. I also removed the nilfs utils and the data2ext4. The data2ext script can be found here. If someone wants to test nilfs you can PM me (but battery SUCKS incredibly )
---------------------------------------------------------------------------------------
Changelog: :
(dec 15): One minor change in assigning a variable. Doesn't change ANYTHING in actual behavior but code it's more "logical" (assigning the output of "busybox ls" to the variable instead of the command ^^ d'oh)
(dec 15) Fixed a stupid error that could lead to exit code (2) ....... and uploaded the proper file for btrfs (not the ext one). Sorry.... -.-
(dec 16) Fixed the fix ....
(dec 16) the scripts create now the folder it needs if it is not present yet (sorry i also forgot this in required ... was only there in the ext4 thread ^^)
=========================================================================
DISCLAIMER: BTRFS is still under development and thus an EXPERIMENTAL filesystem. Please refer to the btrfs wiki for more information.

Quick Info: NILFS2 - data2nilf2 will be much faster then data2ext and won't have Lags.
Long info:
After some thought's how to make things better for data2ext i started to think about how a flash based memory actually works.
Your Sd-card isn't a HDD (as you may have noticed ^^). It is actually a NAND based flash memory wich is divided into pages of 2-4kb and they are grouped to blocks of 128kb-512kb (!). But you will never see these. And you cant never change these (mkfs -b as much as you like ^^). This is done in hardware by a controller. All you will see is - you may call it an emulation - the LBA provided by the "flash translation Layer" (FTL). While the FTL can read/and write per page (2-4kb) it can't overwrite it. It needs to delete the data first AND THIS CAN ONLY BE DONE PER BLOCK !!! (Thats why read mb/s is higher then write mb/s).
What this means. Your filessystem should be aligned on the Blocks and should also avoid the need to erase blocks.
So forget every filesystem that my rock on your HDD (it may prefer e rewriteble sector if it's close f/e. If you "emulate" a filesystem through the controller it should respect the "true nature" of the hardware. A logbased filesystem would be far better since it will more likely take advantage of erased blocks. Also you may want that the blocks of the FS fit on the blocks of the NAND (alignement - but this mathes for every fs).
... Well long story short ... you need NILFS2

Btw: In the XDA thread linked use it for the internal sd in samsung galaxy S for a LAGFIX. Wasn't lag the reason data2ext sucks atm.
My 2nd partition would already use this by now but there are 2 things needed:
-Kernel Support
-mount binary
Im to noobish to provide both ... so .... help ... anyone .... pls ?!

As for mount binary. busybox mount might work. I've just been playing with aufs and normal mount worked for that.

About binary
"Mount -t auto" didn't work with nilfs2 with ubuntu. "Mount -t nilfs2" calls mount.nilfs2 i think.
EDIT: Did you add nilfs or nilfs2?

I would just like to mention here that I made a special note about bloc alignment on sd card on my thread. I provided a link for that and FAT32 can be aligned to the actual bloc 128kb/512kb size of an sd/usb flash memory. This is the reason why I use 2 fat32 (aligned) partitons.

I still don't get the point using FAT for the 2nd partition. Also did you see what ownhere posted here:
Why create a small loopback device? the reason is item 3. But I found some bug with this case, any data write to loopback device need twice kernel IO command, one virtual one real, so the cpu usage will be high

I have used loop so far because I have run some I/O test on my phone (not quadrant) and I always had a better result with loop than with direct format.
ownhere post is great but he's not always 100% right. For instance, the fact that ext2 partition when mounted on /data is not unmounted properly by the system in wrong. You can read my post here http://forum.xda-developers.com/showpost.php?p=9704670&postcount=9 to see the tests I did. I do confirm that the FS is unmounted by the system on shutdown.
About ext4 4K block size, you can do the same with EXT2 (my actual bloc size is 4096).
But I'm reading with great interest the thread about alternatives FS for NAND data storage. The erase block size is different for different devices and manufacturers. But at least if you align blocks to a multiple of 128kb, you will get a noticeable improvement in I/O than no alignment at all.

Well, I don't want to change disk format in a way that breaks

Hello guys, I want to present you the
TEAM WIN RECOVERY PROJECT
(TWRP)
v2.X for our Transformers
This is the touch version of Team Win's recovery project.
It is already avaiable for many devices, but not for ours, so I ported it.
In addition, I am the responsable developer and maintainer for this recovery, so if any errors occur, please post them in this thread and I will see what I can do.
WHY did I port this ?
We do now have a fully functional file manager in the recovery system
The GooManager app lets you now install .zips directly through the open-recovery scripting system
You can queue .zips for flashing in recovery, makes installing new roms MUCH easier !
WHICH features do we have after-all ?
Key Features:
Ability to save custom recovery settings
Default partitions to back up
Default zip folder location
Default color theme (lots to choose from) (Thanks to ffolkes!)
Default Time Zone (for more accurate time stamps)
Zip Signature Verification
Zip md5 Verification (looks for file with zipname.zip.md5)
Ability to flash multiple zips in one go
Ability to select which individual partitions to backup, and restore.
Ability to choose compression or no compression backups.
Compression takes longer of course, but you save roughly half the space. EVO3D's stock system uncompressed is ~800mb, 380mb compressed. You choose.
Ability to auto restore GAPPS on zip flash (for CM based ROMS)
Ability to auto reboot after successful flashes (for the lazy)
Some devices utilize their capacitive buttons in recovery.
Home - Main Menu
Menu - Advanced Menu
Back - Up a Menu Level
Search - Select Current Selection
Battery Level and Timestamp (Better safe than sorry)
Fully working terminal emulator (with exclusive fixes by me)
WHAT does work ?
The file manager
Using internal and external storage mounts
Backup & restore
Zip file installing
Mounting devices
Everything else ?
WHAT doesn't ?
OpenRecovery scripting
You tell me !
A FEW NOTES
OpenRecovery scripting for GooManager and others does currently *NOT* work, this is because the init.rc is missing a recovery boot flag, because of this the GooManager app fails to pass the correct recovery command to our device. This will be fixed very soon !
THEMERS, please take a look here : http://forum.xda-developers.com/showpost.php?p=28605855&postcount=67

I love it when that happens.... I see them now. I will flash it and see how it stacks up to the other touch recoveries.
EDIT: I just flashed it and played around with the UI for a few minutes. I found it vaguely reminiscent of UEFI, and it seemed very useful. I have had a need for a file browser more than once while in recovery, it is a shame though that editing files cannot be done (due to the difficulty level if creating a keyboard, and size limitations, i am sure). It is on my bucket list though, to be able to use some kind of terminal emulator in recovery without using adb. Overall, excellent work, and this will be my recovery if choice from now on! Just out if curiosity, how long did it take you to port this?
I'll be the numb nut that will ask.......what are the fstab zip and the other zip for?
Do i need to flash all 3 zips or just the main recovery zip if i havent got a clue what the other 2 do? :laugh:
No doubt someone would screw it up....... id rather look like a plank!

My faultie, didn't put the explanation in the notes ..
You will only have to flash the TWRP-X.zip file.
The other two zips are the sources needed for compiling.
Of course, those alone aren't sufficent at all. If someone would like to have instructions on how to compile, just ask here.
@Hanthesolo Well, I think it was like one week or so until I figured out how to compile the recovery and another week until I managed to get internal and external storage working correctly.
installed fine
EDIT: its ok i read the op again..........looks good, another job well done Rayman33

Please check if you had ticked "boot" in the backup menu...
Don't backup the boot partition, it won't work, and only give errors.
Just backup the partitions that have an actual size, like /system /data and /cache.
Then it should work; I have tested this.
Also, you can edit the Time Zone settings in the corresponding settings menu in TWRP's home... just look for it.
I'm Trying to mount the ext sd card but its not working.
News :
Backup system does now work out of the box, no need to refresh the menu first.
I nearly found a way to exclude the boot partition from backing up, to make it all more user-friendly.
Fixed version coming the next 2 days.
Stay tuned !

Guys check this out
Best result on Android 4.+
Description
Hey everyone,
So, I was experiencing significant lag as we all do from time to time, and decided I was going to get to the bottom of it.
After tracing and debugging for hours, I discovered the source of 90% of Android's lag. In a word, entropy (or lack thereof).
Google's JVM, like Sun's, reads from /dev/random. For all random data. Yes, the /dev/random that uses a very limited entropy pool.
Random data is used for all kinds of stuff.. UUID generation, session keys, SSL.. when we run out of entropy, the process blocks. That manifests itself as lag. The process cannot continue until the kernel generates more high quality random data.
So, I cross-compiled rngd, and used it to feed /dev/urandom into /dev/random at 1 second intervals.
Result? I have never used an Android device this fast.
It is literally five times faster in many cases. Chrome, maps, and other heavy applications load in about 1/2 a second, and map tiles populate as fast as I can scroll. Task switching is instantaneous. You know how sometimes when you hit the home button, it takes 5-10 seconds for the home screen to repopulate? Yeah. Blocking on read of /dev/random. Problem solved. But don't take my word for it .. give it a shot!
Update!
I've built a very simple Android app that bundles the binary, and starts/stops the service (on boot if selected). I'll be adding more instrumentation, but for now, give it a shot! This APK does not modify /system in any way, so should be perfectly safe.
This is my first userspace Android app, so bear with me!
Note that this APK is actually compatible with all Android versions, and all (armel) devices. It's not at all specific to the Captivate Glide.

UPDATE: Seeder_v7 is out, as suggested by pepoluan, it now detects for qrngd (built in rngd for Qualcomm Snapdragon-based devices), if it is there, then it will not start as rngd may conflict with it...the rngd binary is also using the latest version (it is turned off when screen is off)...users of previous versions can just flash it over...
INSTALLING
You need init.d support for this!
Download and flash:
http://www.androidfilehost.com/?fid=9390248398092764755
Here is a mirror... http://d-h.st/REX
How to use this script?:
After flashing, launch terminal emulator and type
Code:
su
seeder
You will get a menu like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
NOTE: There will be NO app after flashing! This only installs the necessary binaries and scripts...
For those who cannot install via recovery:
You get a status 0 error -> replace the update-binary in Seeder_v6.zip with one from another zip that works with your device
OR
Use the new installation method!
Instructions:
1. Download Seeder_v7_non-CWM.zip from here:
http://www.androidfilehost.com/?fid=9390248398092764756
2. Extract the zip, you will get a folder named "install"
3. Place the folder in the root of your sdcard (/sdcard)
4. Launch terminal emulator, type:
Code:
su
cd /sdcard/install
sh install.sh
5. Ignore any error messages (those are only warnings, only happens to current users)
6. You are done! The script will auto-delete the "install" folder as it is not required anymore...
Sample output:
UNINSTALLING:
And now for the way to clean up Seeder_7:
Via recovery:
Flash Seeder_v6&7_Uninstall.zip:
http://www.androidfilehost.com/?fid=9390248398092764753
Via terminal:
1. Download Seeder_v6&7_Uninstall_non-CWM.zip:
http://www.androidfilehost.com/?fid=9390248398092764145
2. Extract it to the root of your sdcard (/sdcard), you should get a file named uninstall.sh
3. Launch terminal emulator and type this:
Code:
su
cd /sdcard
sh uninstall.sh
4. You are done! Everything gets cleaned up, including uninstall.sh...

FLASH THIS ON GINGERBREAD!?!?!(v1.4.0)
Thanks to Zen Arcade for making a flash for Gingerbread! His Post Here!
I took a look at the original CWM package and made the following changes:
1 - swapped in our update-binary
2 - changed the mount command in edify script (not really needed since system is already mounted in gb voodoo CWM recovery)
3 - removed all mount commands from init.d script (not required since you have to have /system mounted just to read the script)
Here's a link to the CWM flashable: http://d-h.st/Kaq
I'm running this on both my Infuses - no problems noted. At work now so will not have a chance to try with games for a couple more hours at least. Only down side I can note is that the rngd binary is about 1MB in size - a small sacrifice if it does eliminate lag events
Note that this package is for GB, but should work fine for 4.x roms as long as /system is mounted as part of recovery startup. Can someone test on a 4.x (CWM9/10) rom by flashing the zip and then checking /system/etc/init.d for a file named 91RNGD or /system/xbin for rngd? I've already tested on GB and it works fine there.
Thanks bradman for posting this - all credit and thanks to the original devs who posted this.

CM10.1 is smooth as **** with nothing needed... but if this makes it even better, then thats good to hear.

EDIT: i hope it works so my online game will run smoothly!
I must say, this relatively minor tweak provides a noticeable boost. I'm currently using Liquid Smooth RC9.11 with no further tweaks. After applying this tweak I've noticed faster loading times for a couple games, Google maps is much more responsive to massive view changes, web browsing is snappier, and as stated above almost no redraw delay when returning to the launcher after running a large app (like a game). I must say this under-powered and under-RAMmed little Infuse just keeps getting better and better thanks to all the work the devs here. Keep up the good work!

Is best to just fix Perm to brr safe, easiest way to do so if you just install the app is to go to recovery/advanced/fix permissions and reboot

so i just have to flash the zip in recovery then fix permission and that's it?
just flash it will do permission
Working CWM Flashable for Infuse GB
I took a look at the original CWM package and made the following changes:
1 - swapped in our update-binary
2 - changed the mount command in edify script (not really needed since system is already mounted in gb voodoo CWM recovery)
3 - removed all mount commands from init.d script (not required since you have to have /system mounted just to read the script)
Here's a link to the CWM flashable: http://d-h.st/Kaq
I'm running this on both my Infuses - no problems noted. At work now so will not have a chance to try with games for a couple more hours at least. Only down side I can note is that the rngd binary is about 1MB in size - a small sacrifice if it does eliminate lag events
Note that this package is for GB, but should work fine for 4.x roms as long as /system is mounted as part of recovery startup. Can someone test on a 4.x (CWM9/10) rom by flashing the zip and then checking /system/etc/init.d for a file named 91RNGD or /system/xbin for rngd? I've already tested on GB and it works fine there.
Thanks bradman for posting this - all credit and thanks to the original devs who posted this.
UPDATE - 2012/01/03
I've confirmed the documented improvement in speed at which Maps re-tiles the map display when making big location changes. Still testing other apps. Some games appear a big less laggy, although some disruptive lag events still occur (I suspect due to file system i/o scheduler delays rather than from lack of random/entropy data as addressed with this enhancement). I'll do some benchmarking over the weekend and report back with results.

I currently cant test this but if it turns out to work ill put it on OP. i did hear from someone that the biggest difference on GB but i cant say that for y self because i have not tried yet
I gotta say, it's very smooth so far.
Works fine on Scott's CM10. PS shows the rngd process running. Thanks

I really dunno if the tweak makes that big of an effect but I did discover a nice trick to have a nice fat entropy_avail with zero overhead.
One of the first pages I skimmed was http://linux.die.net/man/4/random which mentioned at the bottom these other files:
read_wakeup_threshold contains the number of bits of entropy required for waking up processes that sleep waiting for entropy from /dev/random.
write_wakeup_threshold contains the number of bits of entropy below which we wake up processes that do a select() or poll() for write access to /dev/random.
Normally, read_wakeup_threshold is 64 and write_wakeup_threshold is 128
I also wondered why most users report that their entropy_avail was by default in the 200ish range while mine was always by default over 300.
I had also found this page at linuxinsight. I had used that site alot when researching Kick Ass Kernelizer's sysctl tweaks.
So I thought, hey I wonder if I can use sysctl to set good values and low and behold, I looked in my script and I already have settings for both lol:
Code:
busybox sysctl -e -w kernel.random.read_wakeup_threshold=128;
busybox sysctl -e -w kernel.random.write_wakeup_threshold=256;
As you can see, I had doubled the default values - and that's why my entropy_avail was always over 300.
So I decided to mess with sysctl a bit.
Connected the phone to the laptop.
In one command prompt I watched the entropy_avail with this one liner:
Code:
while :; do cat /proc/sys/kernel/random/entropy_avail; sleep 1;done
In a second command prompt I did the sysctl thing...
I found that write_wakeup_threshold didn't effect entropy_avail at all.
But read_wakeup_threshold is a totally different story
I did
Code:
busybox sysctl -w kernel.random.read_wakeup_threshold=2048
The entropy_avail just started climbing....
All the way up to 3600+ and just stayed there. Never went down at all.
Actually, the more I did stuff with the phone, the faster the level would climb.
So it would never go down and would never get used.
I thought well maybe I should lower it so it does get used.
I kept lowering read_wakeup_threshold until it got down to 1200 and finally entropy_avail dropped to 2400+ and kept climbing until 3600 and then would drop to 2400 immediately and up again and so on...
I played with different values.
Setting it to 1000... entropy would go up to 3000 and then drop to 2000 and up to 3000 again....
Setting to 750.... entropy would go up to 2250 and drop to 1500 and up to 2250 again...
So the pattern is:
max entropy_avail=read_wakeup_threshold * 3
min. entropy_avail=read_wakeup_threshold * 2 (ie. read_wakeup_threshold * 3 - read_wakeup_threshold)
So it builds up 3 times the read_wakeup_threshold and then when it hits that limit, it drops the value of read_wakeup_threshold.
If you want to lock it it at the highest possible value (4096), you'd do:
Code:
echo 1366 > /proc/sys/kernel/random/read_wakeup_threshold
Or
Code:
busybox sysctl -w kernel.random.read_wakeup_threshold=1366
You can add either of those to any init.d script.
However, on my device, it won't go over 3600 so you can test for yourself how high yours will go.
If all you can get is 3600ish just go with 1200 (ie. 3600/3)
In Kick Ass Kernelizer I'm gonna make it like so:
Code:
busybox sysctl -e -w kernel.random.read_wakeup_threshold=1024;
busybox sysctl -e -w kernel.random.write_wakeup_threshold=2048;
That will make it bounce between 3072 max and 2048 min.
I'm making write_wakeup_threshold twice the amount of read_wakeup_threshold simply because that's what it is by default.
But hey, maybe I can save battery life if I make it 1280 just so it stays locked in at 3600+ and it doesn't have to keep rebuilding entropy_avail lol
So conclusion is: since there is a definite pattern on how entropy was being built up to a pre-determined level and dropped to a pre-determined level, it wasn't actually being used. That's just how it's programmed.
If the setting isn't there to "hold" all the entropy, it just drops/flushes it and force feeding it entropy won't make it not spit it out
So at least I found the setting that will make it hold it in lol
Maybe somebody would like to give it a try and test to see if it actually saves battery by setting read_wakeup_threshold to 1366.

Just adding this, after reading the whole thread here it seems like this may be a simpler solution (and better on battery life)

Anyone tried this?
Btw brad im on jvu saurom and flashed it fix permission but this is what i get
Tweak
This relatively minor tweak provides a noticeable boost. I'm currently using Liquid Smooth RC9.11 with no further tweaks. After applying this tweak I've noticed faster loading times for a couple games, Google maps is much more responsive to massive view changes, web browsing is snappier, and as stated above almost no redraw delay when returning to the launcher after running a large app (like a game). I must say this under-powered and under-RAMmed little Infuse just keeps getting better and better thanks to all the work the devs here. Keep up the good work!
