ok, from my android tweaking and playing around with all kinds of settings and other things i know it can be somewhat hard to find everything you might need to make the most of your android device so i will put links to them here along with providing support and my own little discoveries here...if anyone knows anything else that is cool or useful just post it and i'll update this post (btw these are tested on droid 1 only but many may apply to most android devices)
*Anyone who knows of any other tweaks/mods/scripts/useful terminal commands please feel free to post and i'll add it here (after testing it if possible)*
***disclaimer- I am not responsible for any damage you may do to your device, please make sure to have a backup before doing any of these tweaks***
first off how about a simple rooting/returning to stock guide?
quick root guide
1)download these files
http://www.motorola.com/staticfiles/Support/Experiences/Global_Drivers/MotoHelper_2.0.40_Driver_4.9.0.exe
http://wonderly.com/bb/DROID/OEM/rsdlite_5.0.msi
http://wonderly.com/bb/DROID/OEM/VZW_A855_QSC6085BP_RZRECOVERY_UPDATE.sbf
http://wonderly.com/bb/DROID/OEM/update.zip
2)install the first 2 links in order
3)connect your phone via usb to your computer and copy the update.zip you downloaded to your sdcard
4)reboot your phone and hold power + vloume up + the camera button until you see the screen that says bootloader battery ok
5)open rsd lite and see if it recognizes your phone (basically any entry in the model column) and slide your phone keyboard open
6) click the ... near the start button and navigate and select the VZW_A855_QSC6085BP_RZRECOVERY_UPDATE.sbf file
7)click start and WATCH FOR "Phone[0000]: Phone is being rebooted" On your phone the screen will change to "SW Update Complete" and your phone will reboot within a second or two. You want to be already holding the x button on your keyboard to boot into recovery mode when the phone actually reboots so the stock OS doesnt erase the new recovery you just flashed
8) using the volume keys to move through the menu, the camera button to select and the power button to go back, go to install and select the update.zip you put on your sdcard earlier and select install update.zip
9) then select "reboot into android" and enjoy the benefits of being rooted
return to stock
1)download these files
http://www.motorola.com/staticfiles...al_Drivers/MotoHelper_2.0.40_Driver_4.9.0.exe
http://wonderly.com/bb/DROID/OEM/rsdlite_5.0.msi
http://wonderly.com/bb/DROID/OEM/VZW_A855_FRG22D_QSC6085BP_C_01.43.01P_SW_UPDATE.sbf
2)install the first 2 files
3)reboot your phone and hold power + vloume up + the camera button until you see the screen that says bootloader battery ok
4)connect your phone via usb to your computer and reboot your phone and hold power + vloume up + the camera button until you see the screen that says bootloader battery ok
5)open rsd lite and see if it recognizes your phone (basically any entry in the model column)
here are are some useful build.prop tweaks I've encountered along the way, just put the line into the build.prop or modify it if its already in there, save, wipe dalvik cache and reboot
6) click the ... near the start button and navigate and select the VZW_A855_FRG22D_QSC6085BP_C_01.43.01P_SW_UPDATE.sb f you downloaded earlier
7)click start and let it run and reboot automatically (it should work even if rsd lite says the result was fail)
8) you are now on stock unrooted froyo
FRG22D
(optional) 9) go to settings > about phone> check for updates and allow system updates to download and install (allows for a super clean setup if you are planning to re-root)
for possibly better scrolling speed, can be set to any number from 35-300:
# This defines the max event window manager can
# handle in 1 s. We may adjust this # for performance
# reason later
windowsmgr.max_events_per_sec=
change lcd density (already in build.prop), which is like changing the resolution on a windows computer can be anywhere from 140 to 260 (under 200 not recommended because everything may be too small for the phone to be usable:
ro.sf.lcd_density=
dalvik cache virtual memory size (already in build.prop)...can also help performance. set anywhere from 24m to 64m based on how complex your setup is. i.e. tons of apps, in depth theme, memory intensive apps, etc.
dalvik.vm.heapsize=
incoming ringer delay (already in build.prop) sets how soon the phone starts ringing when a call comes in. set between 0 and 2000
ro.telephony.call_ring.delay=
proximity delay. sets how long before screen turns off during call. set between 0 and 600
# Proximit sensor screen off delay
mot.proximity.delay=

# Render UI through GPU instead of CPU
# Comment out if this causes laggy UI (it should speed up UI)
debug.sf.hw=1
sleep mode for battery savings. 0 means power collapse suspend, 1 is power collapse (usually the best choice), 2 is apps go to sleep, 3 is show clock and wait, 4 is wait for interrupt...not sure which each one does or is good for, just know about this little tweak lol
# Battery Savings (Sleep Mode)
pm.sleep_mode=
more battery savings
# When moving through zones or losing signal, having a delay
# smooths out constant disconnects and reconnects, which in turn
# saves a ton of battery life!
ro.mot.eri.losalert.delay=1000
disable sending usage data
ro.config.nocheckin=1
wifi scan interval (already in build.prop) can save battery as well. set from 15 to 999
# Time between scans in seconds. Keep it high to minimize battery drain.
# This only affects the case in which there are remembered access points,
# but none are in range.
wifi.supplicant_scan_interval=

Guide to building a rom from source (credit to chevycam and SnkBitten) - http://www.droidforums.net/forum/steel-droid/196475-guide-how-build-your-own-rom-cm7-source.html
Ok, here's a new section with just general tips, tricks and scripts
Useful terminal emulator scripts run as superuser (su)
*Using the debugging logging to report issues
Code:
logcat > /mnt/sdcard/logcat.txt
wait 4-5 seconds then hold volume up and press f on the keyboard to stop it
if logcat is disabled then do this instead
Code:
dmesg > /mnt/sdcard/dmesg.txt
wait 4-5 seconds then hold volume up and press f on the keyboard to stop it
*Find top CPU/memory using apps. value after -m is how many apps to show, value after -n is how many times to update (be sure to set this value or it will run endlessly until terminal is closed)
Code:
top -m 10 -n 1
*Find md5sum for downloaded files (checks to ensure proper downloads especially for roms, just compare your result to whatever value the rom developer provides and they should match)
Code:
md5sum /mnt/sdcard/(file path on sdcard)
For example
Code:
md5sum /mnt/sdcard/download/SD_9.0.0.zip
*Use swap partition without swapper2.
Add this script to the end of any file in the /etc/init.d folder. If you don't have one just run it in terminal emulator each reboot and run it in terminal first since sometimes its mmcblk0p2 instead of mmcblk0p3 depending on where you have the swap partition (or use the app script manager to make it run at boot. Script manager doesn't run continuously like swapper2)
Code:
swapon /dev/block/mmcblk0p3
And to turn swap off
Code:
swapoff /dev/block/mmcblk0p3
*Setting swappiness
Add or edit this line in the file etc/sysctl.config using whatever value you want, just keep the spaces (open in text editor)
vm.swappiness = 30
Or add this to the end of a script in init.d or run in terminal emulator
Code:
sysctl -w vm.swappiness=30
*Loading a module for apps2sdext (link2sd style apps2sd)
Run this in terminal emulator with superuser permission, substituting ext3 for whatever extension you want loaded (keep the .ko though)
Code:
insmod /system/lib/modules/ext3.ko
or the simple way
Code:
modprobe ext3
*Listing loaded modules
Run this in terminal emulator with superuser permissions
Code:
lsmod
*Forcing a hot reboot to clear caches
Run this in terminal emulator with superuser permissions
Code:
pkill zygote
*terminal tips-
Find list of many possible scripts to run
Code:
busybox
List sysctl commands
Code:
sysct -h
List first or last 10 lines of another scripts output (note | is not lower case L, its a separate character)
First 10-
Code:
(script) | head
Last 10
Code:
(script) | tail
Example (list first 10 sysctl values)
Code:
sysctl -a | head
Finding lines with certain letters/word in another scripts output
Code:
(script) | grep (letters/word)
Example (show only sysctl lines with vm in them) (note | is not lower case L, its a separate character)
Code:
sysctl -a | grep vm
Don't worry more to come soon
Ok, those are the well tested tweaks, now for a few experimental ones. Please make sure to have a backup ready to restore since these ARE experimental and may cause your rom not to load
improve peformance?
Add this to the build.prop
#disable the zygote loader
ro.wmt.blcr.enable=0
Fix app issues? (change it to 0 to improve performance)
Add this to build.prop
ro.kernel.android.checkjni=1
Change the I/O scheduler (effects how your phone reads and writes data)(first line tells you whats available and what you currently have in [ ], then put whichever one you want in the "" after echo, and the last line will confirm the change)
Code:
cat /sys/block/*/queue/scheduler
for i in /sys/block/*/queue/scheduler
do
echo "deadline" > $i
done
cat /sys/block/*/queue/scheduler
Increse overall touch resposivness?
Add these to build.prop
debug.performance.tuning=1
video.accelerate.hw=1
ro.min_pointer_dur=8
Raise Photo and video quality?
Add these to build.prop
ro.media.enc.jpeg.quality=100
ro.media.dec.jpeg.memcap=8000000
ro.media.enc.hprof.vid.bps=8000000
change sdcard buffer speed
run in terminal emulator as superuser (su) or put #!/system/bin/sh as first line and put in /system/etc/init.d (you can change the value in the "echo 512 > /sys/devices/virtual/bdi/179:0/read_ahead_kb" line to suit your needs- common values are 256, 512, 1024, 2048, 3072, 4096, 5120, 6144)
Code:
for i in /sys/devices/virtual/bdi/*
do
echo 2 > $i/read_ahead_kb
done
echo 2048 > /sys/devices/virtual/bdi/179:0/read_ahead_kb
echo 2 > /sys/devices/virtual/bdi/default/read_ahead_kb
or you can try just simply using the simple version
Code:
echo 2048 > /sys/devices/virtual/bdi/179:0/read_ahead_kb
Disable boot animation
add to build.prop (use caution after wiping dalvik, it will appear to hang at the M but its usually still booting up all the way)
dev.sfbootcomplete=0
Use dalvik JIT compiler
add to build.prop (Just In Time compiler is much faster)
dalvik.vm.execution-mode=int:jit
Improve performance?
change in build.prop
ro.setupwizard.mode=DISABLED
Rom dependent tweaks (will only work if these features are included in your rom and most are included in settings anyway, most of the time they are but if not sure then ask the dev) add these to build.prop, 1 is on 0 is off
help to free up unused ram-
persist.sys.purgeable_assets=
stop usb debugging on notification-
persist.adb.notify=
Force capacitive buttons to stay on while screen is on?-
ro.mot.buttonlight.timeout=
Improve screen quality at the cost of performance-
persist.sys.use.dithering=
*reserved*
**reserved**
and one more just in case

btw, i hope i posted this right, I'm still new here to xda forums, i hope i posted in the right section too...if not then someone can go ahead move it (if possible)
Nice collection!
Say, do you have anything specific to CDMA bandwidth?
I know my 3G TurboCharger has a positive effect somehow even though most of the entries are GSM related but hey... every bit helps

I'll try it out but it I'll try it on something where the radio fully works lol, is still being fixed on the ics build but obviously I have to go back to gingerbread to make and receive calls, if it does anything on GB, then I'll test on ics, who knows it might fix the radio issues somehow
A friend of mine just asked me to root his old droid for him to use merely as a multimedia (music & video) and google docs device. Strictly Wifi, no service plan.
i plan on rooting, wiping, and running SteelDroid on it for him:

I came across these tweaks and they look AWESOME. I just have a few questions about some of them in particular.

Can i make 2 scripts in script manager that can do this? or are there any available? I know on such a low ram & low internal storage device, swap and apps2sdext would be INCREDIBLY useful.. any tips on making this permanent? If i can make a script in SM i know i can set it start at boot. But i wouldn't need to do that for a2sdext right? once that's set, it's set and needs no changes right?
Also, would you suggest a custom rom like steeldroid or would i be better off stripping out the crapware from the stock ota rom (froyo) and just flashing a better compatible kernel and using some tweaks & scripts to speed things up a bit and optimize them for his purposes.
Let me know what you think?
thanks!

to the first 4 yes, just add them to the build.prop and for the last ones you can either use script manager to make a new script in the folder /system/etc/init.d
if you dont have an init.d folder then you have to have script manager to run them at boot (i'd suggest having the scripts in /data) and for apps2sdext, i'd suggest using the app link2sd, its basically the only way to control moving apps to the sdcard ext
also the biggest help for low ram devices is v6 supercharger and all the other zeppelinrox scripts
http://forum.xda-developers.com/showpost.php?p=18703418&postcount=5021
and i'd highly highly suggest steeldroid 10, its what i currently run and most of the tweaks i have in this thread are already included in it
and btw if you didnt know, in order to use swap and link2sd you have to format your sdcard and repartition it, the easiest way is installing rom manager, flashing clockwork recovery and there should be an option to partition your sdcard in rom manager (it will erase everything on your sdcard so back everything up)
also i'm going to update this thread with more stuff i've found
updated and cleaned up op
awesome! thanks! yea i know about partitioning the sdcard. I use both swap and a2ext on my htc g2, but they are part of the kernel on the ROM i run, i've never used any other software to initiate them.
Thanks for the tips!
Also, how can ANYONE flash roms from XDA and NOT know about the AMAZING supercharger v6 script!
first of all I want to thank the OP! being how this is not my phone but my brothers. he wants me to root it and install a rom. this thread made everything a whole lot simple.
now to bug you guys.. where can I find a suitable system recovery apk for this phone? I have one installed but it never boots into recovery. also I haz steel droid 10 running.

if you're talking about a droid 1 then the instructions to root should install a custom recovery
If you're talking about a droid x2 as your signature suggests then I'd say try looking on droidforums.net... They are more dedicated to the droid series of android phones and I know any Motorola phone other than the droid 1 is more complicated because of a locked bootloader
You can try downloading rom manager to flash a recovery for either phone I believe
Also if you are already rooted and think you have a working recovery then try installing android terminal emulator from the market and typing in
su
reboot recovery

MS,
I have learned alot from your posts. Thanks for the time spent sharing them. A few questions.
You mention and I have noticed many of the tweaks are already incorporated into Steel Droid X. (I am currently running the rc1 version with the last Deprimed Kernel.) Am am liking it ALOT!!.
Is there anyway you could somehow put a denotion on the tweaks that are already included in SDX? I think it would be helpful, as I certainly would find it so.
How much of a effect did you find running v6 supercharger had given the other changes already in SDX? Any conflicts or issues running it with this ROM?
I am planning on partitioning my SD card as I would like to try the benefits of a swap partition. Upon checking my usage I am considering a 128mb. Seems like a safe size all around. Believe you have posted this somewhere as well? Card is a 32g class 4. I have never messed with running a swap. Currently, I have a standard single FAT32 format part. I have a number of programs already set as loaded on the SD card so I will have to move those back.
I believe SDX has apps2sdext already, correct?
From your post I take I still need links2sd to have the apps to go to that swap partition?
Is there a good link to info on the hows, workings, etc on the swap partition, apps works? I can search for one, only if you happen to have a link handy.
Thanks for all your help.

Since noone was updating it, I provide a working flashable zip basing on this mod. There were more than one problem in the zip, but now I fixed them. Please report:
* if you notice a battery performance improvement
* how much is this improvement
* which MOD are you on
* which KERNEL are you on. This mod works only on init.d featured mod/kernels.
thanks.

Okay guys, I just thought I'd give you my mod for achieving good-great battery life. This is the mod I use in Anthem™ which has given me 50+ hours on a single charge. Feel free to include it in your own ROM or whatever. Giving credit would be nice
First: Here is a flashable .zip of the mod that may or may not work with your ROM. I'd still advise doing it manually.
Sysctl.conf
Step 1
Open up your ROM.zip (or whatever it's called) in 7zip (Windows) or Betterzip (OSX) and locate
sysctl.conf in /system/etc
If it's not in this directory, create it.
Step 2
In your sysctl.conf file, paste the following code and save it.

Step 3
Now we need to enable it. So, navigate to /system/etc/init.d and create a file with the following code:
Code:
#!/system/bin/sh
# grep sysctl /etc/init.d/*
# Load /sys/etc/sysctl.conf
sysctl -p
sysctl -p is what initializes the code.
Just FYI: You don't actually need these lines:
Code:
# grep sysctl /etc/init.d/*
Code:
# Load /sys/etc/sysctl.conf
So this would have just sufficed.
Code:
#!/system/bin/sh
sysctl -p
If the above code does not work for any reason, try this:
Code:
#!/system/bin/sh
sysctl -p /system/etc/
Name your file something like this 10sysctl
Save your file.
NOTE: Your ROM must support init.d. You can do this by using dsixda's android kitchen
Step 4
Save your ROM and install it via recovery
OR
you could just push the files into your current ROM and try them out.

Ok, so what exactly is sysctl.conf?
The sysctl.conf is a configuration file for "sysctl" which is an interface for dynamically changing kernel parameters in the Linux OS. The configuration file contains the following elements, vm.min_free_kbytes, vm.dirty_ratio, vm.dirty_backgroud_ratio, vm.vfs_cache_pressure, vm.oom_kill_allocating_task. There are many other elements within the file, but we will be primarily focusing on these specifically (the vm prefix stands for virtual memory). The sysctl.conf file should be located in /etc (/system/etc) by default. To enable it you need your ROM to execute "sysctl -p" somewhere during the boot process (or shortly afterward). We will also be discussing how to enable it if it is not already done so. You can also run sysctl -p manually to enable it any time after the OS is started.
Now, let’s get down to what sysctl.conf does and how it works.
min free kbytes (vm.min_free_kbytes)
This is used to force the Linux VM to keep a minimum number of kilobytes free. The VM uses this number to compute a pages_min value for each lowmem zone in the system. Each lowmem zone gets a number of reserved free pages based proportionally on its size. Default is 2048kb.
dirty ratio (vm.dirty_ratio) and dirty background ratio (vm.dirty_background_ratio)
This controls how often the kernel writes data to "disk" (in our case the internal microSD system card, not the removable microSD card). When your apps write data to disk, Linux actually doesn't write the data out to the disk right away, it actually writes the stuff to system memory and the kernel handles when and how the data is actually going to be flushed to the disk. These values represent a percentage, the higher the percentage, the longer it waits to flush, the lower the percentage, the more often flushes will occur. Now remember, we are dealing with solid state storage, not the traditional disk platter and spindle. So we are actually able to delay flushes a little longer with solid state versus a traditional hard drive disk.
VFS Cache Pressure
Now here is where it gets interesting! File system cache (dentry/inode) is really more important than the block cache above in dirty ratio and dirty background ratio, so we really want the kernel to use up much more of the RAM for file system cache, this will increas the performance of the system without sacrificing performance at the application level. The default value is 100, as a percentage, and what you want to do is lower the value to tell the kernel to favor the file system cache and not drop them aggressively.
oom allocating task (vm.oom_kill_allocating_task)(enable or disable, generally in Linux this value is either a "1" or a "0," representing as on or off.)
This enables or disables killing the OOM-triggering task in out-of-memory (oom) situations. If this is set to zero, or disabled, the OOM killer will scan through the entire task list and select a task based on heuristics to kill. This normally selects a rogue memory-hogging task that frees up a large amount of memory when killed. If this is set to non-zero, or enabled, the OOM killer simply kills the task that triggered the out-of-memory condition. This avoids the expensive task list scan, which can take mass amounts of time and "hang" or freeze the system.
block_dump (vm.block_dump)
This enables block I/O debugging when set to a nonzero value. If you want to find out which process caused the disk to spin up (see /proc/sys/vm/laptop_mode), you can gather information by setting the flag.
When this flag is set, Linux reports all disk read and write operations that take place, and all block dirtyings done to files. This makes it possible to debug why a disk needs to spin up, and to increase battery life even more. The output of block_dump is written to the kernel output, and it can be retrieved using "dmesg". When you use block_dump and your kernel logging level also includes kernel debugging messages, you probably want to turn off klogd, otherwise the output of block_dump will be logged, causing disk activity that is not normally there.
overcommit_memory (vm.overcommit_memory)
This controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.
0 - Heuristic overcommit handling. Obvious overcommits of address space are refused. Used for a typical system. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage. root is allowed to allocate slighly more memory in this mode. This is the default.
1 - Always overcommit. Appropriate for some scientific applications.
2 - Don't overcommit. The total address space commit for the system is not permitted to exceed swap plus a configurable percentage (default is 50) of physical RAM. Depending on the percentage you use, in most situations this means a process will not be killed while attempting to use already-allocated memory but will receive errors on memory allocation as appropriate.
page-cluster (vm.page-cluster)
This controls the number of pages which are written to swap in a single attempt. The swap I/O size.
It is a logarithmic value - setting it to zero means "1 page", setting it to 1 means "2 pages", setting it to 2 means "4 pages", etc.
The default value is three (eight pages at a time). There may be some small benefits in tuning this to a different value if your workload is swap-intensive.
panic_on_oom (vm.panic_on_oom)
This enables or disables panic on out-of-memory feature. If this is set to 1, the kernel panics when out-of-memory happens. If this is set to 0, the kernel will kill some rogue process, by calling oom_kill().
Usually, oom_killer can kill rogue processes and system will survive. If you want to panic the system rather than killing rogue processes, set this to 1.
The default value is 0.
Panic is a system error that is detected by the kernel.
dirty_expire_centisecs (vm.dirty_expire_centisecs)
How old "dirty" data should be before the kernel considers it old enough to be written to disk. It is expressed in 100ths of a second.
dirty_writeback_centisecs (vm.dirty_writeback_centisecs)
This is the interval of when the writeback daemons periodically wake up and write "old" data out to disk. It is expressed in 100ths of a second.

I had problems installing the zip on UC kernel stock rom. Nonetheless the kind of hack proposed in this mod should work here as well. It makes sense. Is anyone able to fix it?
it was mentioned by the developer that the best to do it is manually
and that custom rom developers can implement it on their roms

Even though sysctl.conf accepts ";", it breaks the conf file and sysctl can't parse it.
Use this instead:
http://pastebin.com/raw.php?i=3tDgbmG3
EDIT:
This file is simply the one in the OP without ";".
FYI some of its values overwrite the values used by kernel developers.
EDIT 2:
And without single quotes.

It should work. Maybe you don't have /etc, but only /system/etc (/etc is just a symlink)
If you run
Code:
sysctl -p
you should get as output the content of sysctl.conf
If you get
Code:
sysctl: /etc/sysctl.conf: No such file or directory
Try with
Code:
sysctl -p /PATH/TO/THE/FILE/sysctl.conf
Where /PATH/TO/THE/FILE/ is, of course, the path to sysctl.conf,

First of all... I would like to give credits to all the owner of this tweaks... This tweaks are not mine... I just compiled them
This tweak never fixes battery drain, it can or may improve your battery life
Let me first advice you that this mod worked for me, and would not fully guarantee that it would also work for you.. I'm using CM9 Alpha 4 with xxkpu as based...
With this mod... Battery life has increased by 25%... I can use the phone for browsing (connected with WiFi) and little gaming for 12 hours of semi-continuous use, it means that I lock the phone from time to time and resume my browsing (background apps still connects to the internet when sleeping) or gaming...
This is a Sysctl tweak with optimized Conservative mod... I have also attached the same tweak but with current Gingerbread system tweaks (I am currently using this, no problems so far)
Use Conservative governor as default after flashing this mod

How to get back to original settting
After all these tweaks if I had to get back to original configuration ?
How to do that.?
I just gave a quick look, nothing more.
01confpowersave has an error.
Right after
Code:
#scheduler cfq
there should be an "if". Or you add an if (I don't know what) or you remove fi; from here:
Code:
for i in $(ls -1 /sys/block/stl*) $(ls -1 /sys/block/mmc*)
do
echo "cfq" > $i/queue/scheduler
done
[COLOR="RED"]fi;[/COLOR]
EDIT: I think 95tweaks makes the boot slow because it wipes the dalvik-cache on every boot (and weirdly it creates a database of the zipaligned files, but it doesn't use it) (and FYI some of the tweaks there are already avaible in CWM Tweaks). The last part of the script is useless (read the last part of this: http://forum.xda-developers.com/showthread.php?t=1587553)
And please Mac OS X users, don't include .DS_Store and ._.SD_Store in your zips.

You need to remove

/system/etc/95tweaks
/system/etc/init.d/10sysctl
/system/etc/sysctl.conf
while it's a little bit more problematic for "update-reloaded-1.9b4-cm9-050712.zip" because it replaces the original SystemUI.apk.

Well, 'conservative' is not tweaked because of the 'if' problem, but there's no problem in flashing it, you still have all the sysctl.conf tweaks. Probably it's better to wait a flashable zip without all the Mac trash files, or manually remove them from the zip.
EDIT:
and I was wrong regarding the slow boot, I didn't read the script well enough.
I'll try to fix these... These mods aren't mine actually.. Thank you for your support...
I was wondering how the Mac files got there, I'm even using Windows...
Edit:
Got it, the mac files are from the original zips...
And the Fi; line should remain there... Well, according to the dev I've talked to, that is a needed command, I have really no idea what it does... But I'll guarantee that it works... Governors changed on boot...
The Fi is for stopping an if command...

And yes, you are right, the governor is changed. The problem is that scripts are not compiled, so errors come at runtime and the execution stops when an error is found.
The error is after the line that changes the governor. As I said, the problem is that conservative is not tweaked (the part after the fi).
Blue and not transparent status bar looks horrible, how to do it to look like before?

I'm really confused... I know very little regarding android yet... What should I change regarding the script so that it will run smoothly...
Isn't this .zip can be flash straight away in cwm then is work just by that? I mean we don't have to adjust anything after flash it

Just flash the zip and it'll be fine...

It's Linux. Just change the file to:
Code:
#!/system/bin/sh
#cpu
echo "300000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo "1000000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo "conservative" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
#scheduler cfq
for i in $(ls -1 /sys/block/stl*) $(ls -1 /sys/block/mmc*)
do
echo "cfq" > $i/queue/scheduler
done
# fi;
#Conservative settings for saver mode.
echo "95" > /sys/devices/system/cpu/cpufreq/conservative/up_threshold
echo "120000" > /sys/devices/system/cpu/cpufreq/conservative/sampling_rate
echo "1" > /sys/devices/system/cpu/cpufreq/conservative/sampling_down_factor
echo "40" > /sys/devices/system/cpu/cpufreq/conservative/down_threshold
echo "10" > /sys/devices/system/cpu/cpufreq/conservative/freq_step
and you'll be done. Don't know what that fi was for, anyway, we want to reduce power drain and then the tricks have to be applied for that.
It will work on any galaxy devices ? Just a question
nooooooooooo, don't do it
he ported it for our device
Did anyone test this ?

+1 and which Zip we have to flash? Which update? In tapatalk i can see this...
Hello, I'm a long time user but a bit of a lurker but have been flashing custom ROMs for some time. Hence my post count is <10 and cannot post in the dev forums to contribute...
I noticed other users in the ARHD 7.x thread are having random reboot issues - http://forum.xda-developers.com/showthread.php?p=39586309#post39586309 - which I was suffering from too. I've been using ARHD since the 6.x days and it's a great ROM!
The new ARHD 7.x was a bit of a let down due to the random reboots. After trying all manner of things, it seems it might be one of two things. I've reflashed and not selected a couple of tweaks in the Aroma installer. So far i've been running for a few days with no reboots.
I've not chose to apply the memory/multitasking tweak and the build.prop tweaks. Not sure which of the two was the cause....
The build.prop tweaks apply these:
I doubt the nocheckin value has anything to do with the random reboots, I'm either suspecting the deeper sleep or bypassing of the kernel error checking? Perhaps a kernel panic is causing the sudden lockup and then reboot. Perhaps the "lock up" we perceive, is the phone doing a core dump?
Code:
#!/sbin/sh
# Extra tweaks for build.prop
echo "# EXTRA TWEAKS" >> /system/build.prop
echo "# Disable Sending Usage Data" >> /system/build.prop
echo "ro.config.nocheckin=1" >> /system/build.prop
echo "# Deeper Sleep" >> /system/build.prop
echo "pm.sleep_mode=1" >> /system/build.prop
echo "# Disable Kernel Error Checking" >> /system/build.prop
echo "ro.kernel.android.checkjni=0" >> /system/build.prop
The multi-tasking tweak applies these values....
I'm not sure if it could be these values being aggressive.
Code:
#!/system/bin/sh
# ========================================
# init.d script for Android Revolution HD
# ========================================
# Tweak minfree values for better multi-tasking
echo 1536,2048,3584,5120,8704,10240 > /sys/module/lowmemorykiller/parameters/minfree
I'll have to test these in the adb shell and see how the phone performs. Will keep you posted.
Hi all,
Unfortunatelly, I'm not allowed to reply to developer posts anymore.
I have to admit that I was inactive quite a while, but I hope someone can reuse my quick fix
and maybe someone could move this post to it's right place.
First of all, thanks to Ryuinferno for the init.d enable script.
[MOD][APK+SCRIPT+ZIP] Enable Init.d for Any Phones w/o Need of Custom Kernels!!!
Finally it works for me very good !!!
The problem was:
/system/bin/sysinit couldn't find run-parts,
so I added the path to the PATH export, and :good:
I modified the downloaded term-init.sh just a little bit.
Changed (line 108 & line 121, line 109 & line 122 optional)
Code:
echo "export PATH=/sbin:/system/sbin:/system/bin:/system/xbin" >> /system/bin/sysinit
echo "run-parts /system/etc/init.d" >> /system/bin/sysinit
To
Code:
echo "export PATH=/su/xbin:/sbin:/system/sbin:/system/bin:/system/xbin" >> /system/bin/sysinit
echo "logwrapper run-parts /system/etc/init.d" >> /system/bin/sysinit
Have fun...
It is better to change the script before you run it,
otherwise you have to change the file /system/bin/sysinit afterwards.
kind regards
Gerry
