I have an LG Optimus T. Not the most ground breaking phone ever, but a heck of a deal for the money. Nonetheless, it's my phone, and I'm not really happy with the internal memory barrier I'm facing. For what it's worth, I have it rooted. I heard a way to partition your SD card (with part of it being allocated to ext3 file system) and re-flashing your phone somehow so the phone utilizes your ext3 partition on the SD card for housing applications. I heard several users in the IRC chat confirm this works well.
However, now that it's show time and I'm trying to do it, I'm a little confused. So please, be gentle, and I apologize if I'm re-hashing simple steps. I'm just trying to make sure I get what I'm supposed to do.
I'm working from this link here:
http://forum.xda-developers.com/showpost.php?p=10692249&postcount=1299
So from what I understand, the factory ROM can do fine, so I don't need to locate a custom ROM. That said, I just need to reset the phone to factory settings (thereby getting the factory ROM), run A2SD (is A2SD any different from A2SD Killer that they speak of in this post? I never heard of it), then go through the motions of the initial setup as it suggests (language choice, time zone, etc).
Then, prior to setting up my gmail account, I'm supposed to reboot to recovery. What does it mean reboot to recovery? Am I supposed to hold down the keys to do a factory reset? Is that what they mean by recovery?
I hate to ask these questions in a form of hand holding, but I just want to make sure I'm doing it right. After re-hashing this post several times and talking to 2 buddies about it without any further progress, I figured I'd just ask.
That said, can anyone help guide me in the proper direction? I'd greatly appreciate it.
Thanks!
make sure that you are looking at the right forum next time that link was for htc desire (use it only if it says its compatible for your phone)
before you start worrying about a2sd, you need a custom recovery, found here. once you flash recovery and boot into it, everything will be clear (ext, partition, flashing, etc)
for apps2sd, id suggest using ungazes data2sd (apps2sd and data2sd are basically the same thing, at least thats my understanding)
follow the steps there. if anythings unclear, post any questions and ill check back later
I did notice it was an HTC forum, but I was speaking with users who had other devices and claimed they used the same method, so I didn't think much of it. At that point I figured it was more of an Android thing vs an actual manufacturer thing.
When you speak of the custom recovery, what *exactly* does that entail? I was told Android phones have the hard factory reset that cannot be altered as long as you don't mess with /system under root terminal. That said, this phone is pretty much brand new. I have nothing on it that isn't already stored in the cloud somewhere (google contacts, gmail, work's email, etc).
What I'm trying to get at is, is a custom recovery needed only to get my phone back the way it was before I screwed with it? Or if I'm accepting to doing a hard factory reset, is that acceptable as well?
Thank you very much for the link. This seems a little more straight forward than the last one was. I'm also trying to understand the differences between handsets and Android versions here. For example, you mentioned the previous post was for HTC. It's a difficult thing for me to grasp because I come from a very heavy Linux background. If I mess with Ubuntu on one machine, then mess with Ubuntu on a top end server, then tinker with it on a laptop, it's still Ubuntu no matter what machine it's on. So it's hard for me to grasp the concept of Android acting differently on different machines (phones) and having different methods to different devices.
That said, it sounds like the link you posted to me is more of a generic "everything should work" type of scenario. After all, it's just moving /data. It would make sense that it would work that way, right? If not, please correct me, as I'd rather be wrong 1,000 times over again and be corrected than make 1 mistake and mislead someone or brick my phone.
Thanks for your response. Hopefully the recovery thing isn't too much of a hassle and I hope this ext thing can do the trick! What kind of difficulty is involved here? Is this fix, say, grandma approved? Or is that asking for a lot?
EDIT - Also, I noticed you spoke of Apps2SD. I have that installed... is that not acceptable to what I'm running? After all, it just seems to move what parts of the apps it can to the SD card. I was aiming to have the entire application base MOVED to the SD card. Is that what it does and I'm just a little confused??
i understand what you mean (how ubuntu on one machine is the same as ubuntu on another)
its the same thing with android EXCEPT that each android device is made different by the hardware (i.e. my phone is limited by the fact that its cpu is not powerful enough to run some apps; different components make up each device in contrast to lets say iphone, where each iphone is the same; my understanding is that each rom utilizes and has commands for each of these components so if they're different then youll need a rom unique for each device)
heres a general scope over recovery:
custom recovery - allows you to flash a rom, make/restore a nand backup, well it allows you to do a lot of things
stock recovery - only a hard reset (done automatically)
a hard reset wont cut it if you screw up your phone. youll need a custom recovery (which allows you to back up your entire system as a nand backup)
when you say apps2sd, i think you are talking about moving the app to the sd card in settings. thats not true apps2sd. true apps2sd moves the whole app to the sd card, giving you unlimited space to store apps (well actually you are only limited by your sd card)
if i missed anything, tell me. im multitasking right now (sorry)
Hahah, no you're doing quite well for multitasking! I understand what you mean, and it makes sense to me. I mean, after all, isn't it still the same analogy to Ubuntu? (at first I didn't think so, but now I think it may be more relevant) After all, if I'm running a dual proc 6 core system with 24gb of RAM, it'll certainly move Google Earth (aka, an app) faster than a Pentium 3 with 128mb of RAM would, even though they're both packin Ubuntu, Fedora, Debian, or whatever your flavor may be. So in theory, I suppose you can apply the same analogy from Ubuntu as you do Android. The catch is, Ubuntu (or any Linux distro for that matter) runs on old hardware great, so the gap between old computer vs super computer is less relevant than today's Android based smart phones, where 300mhz could mean whether or not you can run a certain app. Compared to real life, Ubuntu operates just as quick to me on my dual proc 6 core (12 core total) server with 24gb of RAM as it does my P4 1gb RAM box on my test bench.
Anyway, going back on topic a bit more... yeah I was thinking of the Apps2SD from the market. So I suppose the "real" Apps2SD is a true "mv -R" type of application (linux recursive move of data).
Okay, so get the market based App2SD out of my head. Gone. Done. Okay... the thing I'm still not understanding is the recovery. I mean, I'm looking at the hard factory reset as, say, a recovery "Ghost based" partition that some Windows computers often come with.
Example - Windows gets fubar'd. Reboot. F8. Recover system. And it dumps the recovery image on the main partition. Ta da! Just like it was when you bought it at Best Buy!
I mean, if I could get it back to factory, then I could just start over, right? Trying to put it into words as best I can... I was thinking of it like this.
Hard factory reset = Windows recovery image from Dell factory (back to day 1).
Nandroid custom reset = Own "self made" Clonezilla/Ghost image (customized with your stuff as a backup you made yourself)
That's what I was thinking. So that being said, am I absolutely positively required to do a custom backup? Can I not just rely on the hard factory reset to take me back to day 1 from when I got it from T-Mobile and (if I so desire) start the process over if I tank it? You see, I was told that it's nearly impossible for me to permanently brick an Android phone, as the hard reset, while inconvenient since it would wipe my stuff, would at least get me back to a bootable, functional ROM.
If I'm re-hashing unnecessary things and just need to focus on the fact I have no choice, by all means, e-slap me. Thanks for your help so far. I'm just trying to learn what I can! Your time is appreciated.
the thing is, a time may come when you cannot even boot your phone (lets say you were messing around and modding and all of a sudden you get stuck in a bootloop) and you try doing a factory reset but it doesnt work. this might be because something is corrupted. for android, a factory reset only wipes the data but does not restore anything. this is where custom recovery comes in handy. not only can custom recovery do a factory reset, it can restore a backup if your phone ever gets screwed up (unless you screw it up so much that you cant even access your recovery, then things get much more complicated). think of this backup as a system restore on windows (creating a restore point on windows is like creating a nand backup in custom recovery)
and dont worry about all the questions a few months back i never knew this myself so i understand
Well my friend, your patience is certainly appreciated. I understand a little better now. So let me throw out another analogy just to further solidify what little understanding I feel I have.
Factory reset = Windows restore point
Nandroid reset = Self made recovery image via Clonezilla/Ghost
Your point is a Windows restore point is only good as long as the system is solid. If your hard drive dies, suddenly your backed up restore point is useless. But... dump on that Clonezilla/Ghost image you have saved elsewhere and you're good to go.
That said, how should I get started? How do I make a Nand backup? Any guides you recommend? Will this back up my current apps, settings, etc?
Once done, how would I go about the actual Apps2SD method for making the SD card act as app storage? I assume it's that ungazes link you provided earlier?
Again, thanks for your help!
Figure this is where I should come in to help. You can install Amon_ra's recovery or clockworkmod onto your device (you can choose if there is both) but you should be able to do all that from a backup and restore menu in the custom recovery. You can go get the free version of rom manager and it should be able to install clock work recovery all without that much input from you, then you boot into recovery from rom manager. It shows you this simple yet amazing GUI that you never thought possible with something so small such as your android device. You are then given choices, do you want to flash a zip to mod your system such as custom roms, new keyboards, etc. Backup and restore (nandroid backup) or even mount it in USB mode which is useful if you never backed up, and didn't keep a copy of a custom rom on your SD card. (I never made that mistake of atleast the latter option. lol) So basically, the recovery is the "safemode" of android, only you don't get to access all of your stuff until you leave "safe mode"
and a bit of advice: NEVER flash anything without 50% or more battery.
It probably will atleast softbrick your device if it dies mid-flash.
oh, I see. Yeah I thought recovery was the actual PROCESS of pulling an old backup over, not so much operating in a sterile system environment such as safe mode.
About flashing, I would suspect it would best be done plugged in with AC power. I've had a laptop or two nearly die on me in my flashing days (went to the bathroom, came back, flashing red light, uh oh!) so I think I'll be good there.
So which applications do I need to get started? The problem I face is when I google something, there's no less than 600 ways to do all sorts of various tasks. So I have a hard time separating which one is best practice, which one is the old method, which one is definitely a bad idea, etc. So you say I can choose which ROM to use. Are they pre-built into whatever recovery software I need to use to get this job done? Or do I have to download them somewhere and put them on my SD card and then boot into recovery?
EDIT - hey how about this lil guy here?
http://code.google.com/p/android-roms/wiki/SPL
Came across it when I was googling for Nandroid Backup.
EDIT 2 - Or this guy. Looks to be the same step as the Nandroid step within the first link. Looks like the first link, while a bit more dated, is also a bit more thorough.
http://theunlockr.com/2010/02/06/how-to-backup-and-restore-your-android-phone/
Since you're rooted, you can run thiss https://market.android.com/details?id=com.koushikdutta.rommanager&hl=en and it will be able to install clocwork mod recovery. Then you just boot into it and whatever rom you want to use (found in the android development forum for your device) you install that zip from SD card and voila! You're golden with a new rom on your phone. It isn't completely needed though. lol
if i were you, i wouldnt use rom manager (it is known to cause problems). for now, use the recovery i posted in the second post. if you want to flash a rom, heres a list of most (if not all) roms for our phone.
as you start getting familiar things, you should start referring here
heres a general scope of things when it comes to flashing a custom rom:
1. boot into recovery
2. make a nand backup
3. you MUST wipe data/factory reset, cache, and dalvik cache. wiping the sd card is not necessary
4. flash the rom
5. boot normally (first boot can take awhile)
and remember, never flash more than one file without rebooting normally in between or else you might run into some problems
When you say wipe the dalvik, cache, etc, is that done during a factory wipe or do I need to do that in a separate step?
Edit- which rom would you suggest? I hear a lot about cm7. Thats the only one I recognize.
they are separate processes but they are found under the same category
so itll be like this:
wipe
wipe data/factory reset
wipe cache
wipe dalvik cache
wipe rotation settings
wipe battery stats
something like that (at least this is how it works for amonra recovery. for clockwordmod recovery, i believe they are categorized differently but its still the same idea)
Ahh, I gotcha. I remember reading instructions on clearing the dalvik-cache, so that's why I thought maybe I'd have to re-hash those links I found and do that in a separate step. But it sounds pretty streamlined!
Well, I'll give this a shot tonight. I'm still going back and forth on which ROM to use. I hear a lot about CM7, but I also heard of 1 or 2 users saying on CM7 they lost their Google Navigation or Google Latitude functionality, both things I utilize. I also had no idea the Opt T was supported on CM7. But then again, if it's anything like Linux distros, using one of the more popular ROMs has its benefits as those are normally the highest supported.
People weren't lying when they said stop googling and just go to XDA forums. Thanks for the help yet again, bro.
im using cm7 and both google navigation and latitude work for me. and i know that the link i gave you said optimus p500 roms, but all p500 roms work for the p509 (since they both use the same hardware). just remember not to flash any roms from any other forums, flash only from the p500 forum
glad i could help. if you need any more help, just refer to that forum or pm me (since i have the same phone as you)
Sweetnsour, I was just suggesting Rom manager to be able to flash clockwork, then he could flash amon_ra from inside clockwork. I think that's possible? It was more of a hint for a newer user. I remember being on the other side and since I don't personally own your device, I was just offering general android advice. Glad to see you corrected me though, anyway, good luck OP. Hope you enjoy your device modifications.
I come here with my tail between my legs ducking from any backlash I may get from any users here. I spent the better part of the evening Googling around, asking in IRC, and trying to get this part working.
I ran into several issues. Some of them are quite comical to me.
I Googled around, as well as utilized the links that were provided to me in this thread. I learned that Clockwork and Rom Manager are from the same dev team, but they are two separate products. Likewise, I was hearing other users confirm that Clockwork is the bees knees but that Rom Manager is kind of "ehh" with predictability and reliability.
After I ran into some road blocks I ended up asking in the IRC Android chat room. Some users in there directed me to some guides. I read through them. Of course, each one was different. So to a user like me, I have no idea which one is the better one to go with. The one guide kept talking about how I need to run a .sh script. So, of course, I download the files supplied and extract them. No .sh script. I ask in the IRC chat and I caught hell because I should read the directions more clearly. I read through them several times and got no where. Ultimately, some users in the IRC chat decided to link me to the guide they recommended. Later, I too ran into a road block there.
Moving along, I went into the XDA-Devs chat once I found myself at the next road block. There some users spoke to me about what I was trying to do. I linked to them the guides the Android users told me to use and they were wondering why I was using such old guides to do this simple task.
This is where my frustration is brewing. There are a million and one ways to do everything. There's no structure. No consistency at all. I've done a ton of reading and I still feel like I know next to nothing about doing a "simple" recovery. I know phones are different. I know ROMs are different. But holy hell. Doing "xyz" task on one Android phone vs the same task on another Android phone is as different from driving a lawnmower vs a dump truck.
At this point I installed Android SDK on my Ubuntu machine. However, "adb shell" was yielding a command not found error. It's nearly 2 am. I'm packing it up for tonight.
That said, let's back up a bit here. My goal is this. I have an LG Optimus T. I have it rooted. I would like to utilize Clockwork in order to do a recovery as Clockwork came heavily recommended by many sources I read about. Then, I would like to utilize the XDA site for a list of available ROMs for my phone and choose one of my liking.
Is this guide, right here what I should be using to get this job done?
Along with that, how exactly do I need to install SDK on Ubuntu so it works without headache?
Thank you to everybody who has been patient with helping me learn this stuff so far.
that guide works. after you flash the recovery from that guide, don't think that you are always stuck with it. you can always flash another recovery in recovery. as for sdk, do you need it to flash recovery? those commands to flash recovery can be done on the phone using a terminal emulator. (about installing sdk on ubuntu, I will check on that tmrw because I'm doing this on my phone, and over where I'm at I should be sleeping)
EDIT: and here's a list of roms for our phone http://forum.xda-developers.com/showthread.php?p=16535249
EDIT: for sdk, have you tried this?

Okay. I wasn't sure if it was safe to run those commands from the phone. I was tempted to but, ahh, figured I'd wait.
Now these instructions are exclusive to the Clockwork mod, correct? So if I get any other recovery (Amon Ra, for example) there will be specific instructions for that exact recovery too as well, right?
I'll give this a shot later and see where I end up. Thanks for your help!
Edit... It's a shame those commands aren't in an sh script already. Just a fun idea... What I'd add them to a blank text file and on the phone just chmod +x it and run it. Would that work??
the commands are fairly similar:
cwm (from your guide):
#mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
#cat /sdcard/flash_image > /system/bin/flash_image
#chmod 755 /system/bin/flash_image
#mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
#flash_image recovery /sdcard/recovery.img
#reboot recovery
amonra (from here):
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
# cat /sdcard/flash_image > /system/bin/flash_image
# chmod 755 /system/bin/flash_image
# mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
# flash_image recovery /sdcard/recovery-RA-GNM-thunderg-1.1.0.img
# reboot recovery
after you flash either cwm or amonra, you wont have to do this again when you flash another recovery. to flash another recovery, you would just have to flash the recovery zip in recovery. these zips can be found here
So, I'm playing with recovery... In particular, I'm working on replacing the stock recovery with CWM Recovery. A good nandroid backup is always the first step to hacking an android device.
I've managed to repack the recovery partition (finally) as unsecure (meaning I can boot into recovery, adb shell into the device, and have root access.) While in here, I'm just noticing something different on the tablet:
It appears that the firmware update from kies has added some odd bloat: the default factory recovery starts by copying several items from a "preload" partition to your /sdcard partition. How nice of Samsung to add even more addition BLOAT to our devices. (I'll be removing that aspect of recovery, I promise.)
Another oddity I'm finding is that, normally with these devices when they are booted normally (and adb is able to connect), the commandline "adb reboot recovery" will reboot the device into recovery mode. That does NOT happen with this tablet (but I'm not sure why.) I have to power down and power back on with the proper volume switch held down.
Okay... time for me to build a copy of CWM Recovery that'll (hopefully) work on this tablet. Wish me luck!
Gary
Thanks in advance! Always glad to hear the interesting finds in a new device.

ah, yes... the "new" shared partitions in honeycomb (and ICS.) No longer is there supposed to be dedicated space for /data and /sdcard partitions. They are supposed to use the same space.
Actually, that makes sense. You never have to use something like app2sd, because it's all really the same space. How it gets there, however, is annoying (when trying to reverse engineer a gingerbreak CWM recovery to a honeycomb device.) There is no /sdcard parition on this thing. /sdcard is actually a remap of the /data/media directory. Nice.
My problem is getting CWM Recovery to understand that. pfft.
I wish I could find some source for a CWM recovery partition for another honeycomb tablet. that'd make my life easier, I think.
WARNING: Playing "world of goo" is a major distraction to getting other things accomplished.
have recovery making a nandroid. This would probably be easier if I knew what I was doing. Oh, btw, who wants to test this stuff for me?

Hey,
I'm also working on it, I'm an dev who ported CWM to the Galaxy Note.
Wait a few hours and you will have CWM

I might have just beat you to it. I'll give you a hint, though: honeycomb does some things with partitioning thats very different from previous android versions. CWM tries to take some of that into account, but because of how /data is set up in recovery.fstab, it's not detected that /sdcard should really be /data/media. (I'm rambling.. heh..)
Anyway, pershoot worked this out, so if you pull a specific changeset from his github (https://github.com/pershoot/android...mmit/6dacf061b8476c3e3e2857ca078df95706d62770), and apply it to the CWM in the current cyanogen 7.2, everything should work.
Well, so far everything appears to be working. I've validated the backup works, but haven't verified the restore. I've also modified the code to discourage people from partitioning their sdcards (and it's a bug in CWM that they can choose that option when /sdcard is just a symlink to /data/media)
Anyway, I'll dump the image someplace if anyone wants to mess with it. I honestly have NO idea how to build any kind of package to automate installing it. I've been using "dd" all night long.
On second thought, maybe I'll go to bed... (been awake for over 24 hours)
I'm in the middle of testing the nandroid restores, and there's no way I'll post anything until I'm sure it works. Considering how tired I am, I'll feel better testing this when I'm rested.
One issue I'm REALLY getting annoyed by: For some reason, when I do a "adb reboot recovery", the tablet doesn't reboot into recovery. Even if I'm in a root shell, "reboot recovery" isn't taking me into recovery.
Good night!

Is on this device the Download mode?
I compile my kernels from source, now I need a tester who don't care about warranty.
I use a module of the SGS2, I've contacted a few people experieced in param.lfs, and they say if the kernel can't mount it it says "logo.jpg not found" and it still boots further.
PM me if you are interested!
posted CWM Recovery.
this is habit forming.
the upcoming version will, in addition to being in a nice update.zip, will also install 'su' so you can root your tab and install recovery all at once.
I am _not_, however, installing the SuperUser application (which is needed as well.) That can easily be done from the market after installing this update file.
All will be documented soon.
I could swore I had an sdcard partition, under it's own or external
Sent from my GT-P6210 using xda premium
For the internal, it's not a real partition. The "/mnt/sdcard" mount is a FUSE link to /data/media. (It's a real parition on the external sdcard if you have one installed.)
I'm working with someone to get copies of the recovery and normal boot kernel partitions from the P6200 (international 3g.) Once I have that, and assuming my blind kernel compiles actually work, we'll have CWM recovery for that tablet as well.
Take care
Gary
I have an international 6200. If you tell me what you need and maybe some help in how to get it, I will dump whatever you want.
Z.

BTW, have you confirmed that recoveries are incompatible between variants? The 10.1 was "one recovery fits all".

Currently, they all share the same "recovery" binary (entire /sbin directory, actually), but they need different recovery.fstab files in the initramfs due to different /system (and /data, I think) locations. I'm not at home, so I can't check if it was only 'system' or both.
That one file being different causes them to have a different initramfs, and therefore a different zImage (recovery.img.) I once considered using init.rc to dynamically put a different recovery.fsab into place based on the tablet model at runtime, but how would I be able to determine the tablet model dynamically? default.prop would be useless (as it's also part of the recovery initramfs) and it wouldn't be a good idea for the RECOVERY to rely on the existance of valid data on any other partition. There are ways to take educated guesses based on partition counts and other strange things, but I don't think it's worth the risks.
I do have to admit that I've been having fun messing with this stuff.
Take care

Ah, that's odd/rare - kind of disappointing.
As always, READ the ENTIRE OP...
If you are having poor performance/battery life and want to help me finalize a project/ addition to the 1-Click Gremlin Remover, let me know...
Awesome! So now that I have a few people that are willing to test that have protential gremlins, I am introducing a possible addition to the Gremlin Removal process. This method is a less destructive technique as oppose to reformating everything and starting all over again (aka the 1-Click method).
This is mainly intended for those who are only experincing less malicious gremlins, meaning you aren't dropping 20% battery every hour, have extemely laggy performance with FC's, etc. However, it is possible that this method could fix even the most extreme performance issues (or not do much at all...lol)
**Make sure you have adb installed on your PC**
Step 1
Download the System Cleaner.zip and copy to the root of your sdcard (see attachments at bottom)
Download the tune2fs.zip, unzip it, copy the file (tune2fs) to the root of your sdcard (see attachments at bottom)
Plug phone into PC via usb
Boot into recovery
Open cmd prompt and type:
Code:
adb shell
cp /sdcard/tune2fs /tmp
chmod 777 /tmp/tune2fs
Now we have our filesystem check environment in place.
Step 2
Unmount /system, /data, and /cache (we can leave the sdcard mounted)
Open cmd prompt and type:
Code:
adb shell
/tmp/tune2fs -l /dev/block/stl9
/tmp/tune2fs -l /dev/block/stl10
/tmp/tune2fs -l /dev/block/stl11
In the output of all three partition checks, you need to look for one of these variables:
Code:
Filesystem State: clean
Filesystem State: not clean
Filesystem State: dirty
If it is "clean", this may not do much for you. If it is "not clean", you didn't unmount that partition. But if it is "dirty", this will fix many issues.
Step 3
Regardless of which state your filesystem is in, we can still run the System Cleaner.
While in recovery mode, flash the System Cleaner.zip as normal. It uses the Aroma Installer so just run it as you normally would. Notice that you only have 1 option to "install" or run the cleaner. I plan to add more to this project, but I want to get the base of it up and running.
This is a fairly quick process but allow it to run fully without touching the device. You will also be prompted to restart or not. I haven't gotten that option working correctly so it doesn't mattter what you choose, you will still have to reboot manually. When the installer is done, click next, finish and you will go back to CWM.
Step 4
After the filesystemcheck is done, run Step 2 again and note your fielsystem state (especially if it was dirty).
Step 5
Reboot the phone and monitor your performance, etc.
A bit of insight into what this is/does:
This method is using a binary called fsck.ext4. Broken down explination:
Code:
fs= filesystem
ck= check
ext4= filesystem type
Pretty redundant I know.
Now, what it does, is runs a filesystem check and defrag, much like windows disk check and defrag. It fine tunes the file systems, realigns things as needed, and cleans up the system. Just like our computers, our phones need a good cleaning from time to time and this little thing will do just that...lol
Again, this is just the base for a larger project...

I get around a day out of it which is really all I need..
I'm up for testing Thomas.
Edit: OK I just got home. Will post feed back in a bit..
Edit: Well all my partitions were clean. Flashed System Cleaner anyway
Im on VB, and it has great standby battery life, but it nosedives once i start using it..

Try Lightning Zap v5 for better battery life... Link is in my signature
flashed it before restoring any apps.
its working wonders performance wise, lets see how battery life goes as it soaks in hehe
My phone was clean on all volumes... Commands worked fine and and ran system cleaner just for testing purposes anyways. All is well
Awesome to know it is working, now I just need someone who has gremlins from multiple flashes and what nots to see how well it fixes things...lol
Thomas,
Are you sure that defraging is necessary on a flash drive... with SSD (solid state drives) it's even doing more bad by wasting limited amount of erase cycles. And btw, fragmentation does not affect reading speed as much as with regular HDD because of very low latency.
During defragmentation (if utility is not aware about how flash memory works) there might be multiple P/E cycles on a typical block of 16, 128 or 256KB.
There are utilities which will erase free blocks on SSD - fill it with "1" so that next write to such blocks would be faster. Does your utility do something like that?
Ill be willing to test it for you.
50 flashes and no clean ups yet.
Don't have gremlins thou.
it pm the results later.

This "defrag" is for our devices... fsck have been used on android phones for some time now... It isn't a true defrag as you would think with a normal hdd. But it is the best way of explaining it.

i followed your instructions. i notice it was like this today i turn my phone when i woke up this morning. i wonder what happen did i do something wrong..
All clean here. Looks like it might be pretty hard to find someone with a dirty filesystem.
i cant flash anything now will odin fix.
If you are going to flash and ICS ROM after this tool please make sure to first install a GB then ICS otherwise your SD card will not be accessible. I am trying to find a fix but it has been illusive. This statement will be removed once a fix has been found and OP updated.
Now with CWM Touch!
This method uses NVFLASH to recreate all partitions and formats them, thereby getting rid of the file allocation pointers and hence renders data inaccessible without effort.
Note: I have never seen a file come back to life or its data affect other files without effort on the users part or a temporary glitch once the partitions and pointers have been overwritten. Please post a reply with evidence if you have seen it.
Benefits:
The contents of the zip file can be used to super clean G2X before a new ROM flash. This tool recreates all the partitions in the phone so wipes the pointers to all files (everything). The method it employes has existed from before. The files here will stop short of pushing a ROM, so that you can push your favorite ROM.
Prerequisites:
G2X (Will not work on O2X due to different partition table)
Desire to have a clean install of your favorite ROM
Backup your data
*** WARNING ***
This tool will wipe both phone internal memory and internal SD card. External SD card content is safe.
Don't say you haven't been warned!
What to do:
Download the attached Zip file.
Take out the battery (assuming you have backed up your data on external SD card, computer or elsewhere), connect the device via USB while holding VOL+ and VOL- together. Don't let go of the volume buttons until the device is recognized.
(I typically leave Device Manager open to see when it shows up in the list under "USB Controllers").
Launch flash.bat, sit back and wait until the process finishes (generally a good idea to open a command prompt, CD to the directory and then run the file).
Unplug, put battery in, reboot into CWM recovery (pushed by this tool) by holding VOL- first, then pressing and holding POWER).
Flash your favorite ROM.
Enjoy!
I made this package because I could not get the bluetooth to work with G2x GB 2.3.3 (and below). The issue was a disconnect problem where both the phone and headset would still think they were connected but in audio would not be routed for a call or media. After this procedure my phone has not had an issue for almost 3 weeks now. I have tried it with two ROMs and 3 different headsets without any issues.
I guess I will not toss this phone after all .
Putting it out there in the hope that it may help others solve some of their issues as well. I suspect bad data stays in places not touched by other methods.
Your comments are most welcome.

The real test is how stable your ROM would stay with this method to wipe than any of the other methods.
I guess only time will tell .
wow this method really blaze hellfire much thanks to your( you) & (rom dev)
Ohh I like this. Thank you for sharing .
This thing is faster than nullifier, and I especially like how you don't need to be in CWM to use it. It just seems like doing it in "update mode" would allow better manipulation of the phone's internals.
so this tool DOES format and nullify in addition to recreating the partitions?
deleting and recreating partitions does not remove data. only by writing over existing data can you get rid of it (like nullifier does)

He states in OP that it doesn't write anything, therefor doesn't "nullify". It formats and partitions.

Actually you are right. Deleting, recreating and formatting partitions does not get did of the 1s and 0s, so in that sense the data is still there. However the pointers are gone, and hence even though the data is still there it can't be accessed without effort.
What do you think the nand has on it when the device is shipped... I can assure you its not ask zeroes!

Well no, it has a next to worthless version of android Also, the point he was trying to get across is that it would be better for you to present the script for what it is and not try to compare it to other scripts that do something entirely different. You do kind of imply that you accomplish the same thing as the Nullifier script and more, when in fact you simply do something different.
Some may and probably will prefer your script, at least for specific purposes, while others will prefer the Nullifier script.

Done. OP updated to reflect. Thanks for clarifying that. It was not my intention to state that this tool does anything any other does, or does not.
I think we are all trying to do the same thing... get rid of the issues when swapping ROMs like _____. I can't seem to think of a good analogy here .
thanks for clarifying the OP, that makes much more sense
and no i wasnt trying to say you were reinenting the wheel, just trying to understand what your tool is actually doing
and also i do understand that it would take effort to get data off any type of storage device once the partition has been erased. i deal with wiping hard drives in a data center all the time. we use a DOD wipe tool that writes 1s and 0s over a drive a minimum of three full times to eradicate the data
but with this tool doing it outside of CWM, it sounds like it may do a better job of it
but i must ask, why do you need to push CWM? what if i have a newer version of it already on my phone?

There is no need to push CWM 5.02. As I said in the OP it is a mod of the script found in the reference. In that script it was pushing default recovery. Since the recovery partition is being overwritten as well you will loose existing one and you need a recovery to be able to push a new ROM. Hence the need to push recovery (instead of using super one click).
As long as the recovery is not bigger than the partition that holds it we should be able to push a newer version. However I can't leave it empty or people will look for me with a shotgun (myself included ).

I was thinking the same thing but seems easy enough .. add the cwm img to the dir and edit the .cfg file. Hopefully that should get the new CWM flashed
So would it be benefitial or pointless to nullify to clear the data then run this script for a... super clean?

Ok so question, why are you killing all the data on your internal SD card? Why not just the individual partitions that the phone uses? Your destroying data that don't need to be destroyed before flashing a rom...
Sent from my LG-P999 using xda premium
It does not have to be destroyed. I just haven't had a chance to test without recreating emmc yet.
Next step. Likely tomorrow. Would like to test before release.
Sent from my LG-P999 using XDA
[edit] BTW, I do want to restate that there is some data that needs to be destroyed which is not being taken care of by other methods. I don't believe it is in the emmc, but rather it resides in one of the other partitions. Most methods out there are only working in the /data, /system and /cache domain.
My original problem (bluetooth disconnect) which happens to be a problem for some in the community even now was only completely fixed by this method.
Hi Guys,
I have a Samsung Tab 2 GT-P5113, rooted, and love it. I had to install drives and use Odin to get this ROM installed but it worked and it worked really well. Um, this is the one I used:
http://www.androidauthority.com/galaxy-tab-2-10-1-root-clockworkmod-recovery-cwm-95536/
It is great, I love it, but it is not Jellybean. I have 4.0.4. Now I have ClockworkMod, love it, it really works well. So I downloaded the Milestone zip from here:
http://forum.xda-developers.com/showthread.php?t=1892046
I got the gapps to go with it, and used CWM to install it. CWM works really well, I rebooted to the CWM boot screen and chose the zip file, wiped all caches, and I did pick the make a backup first option and performed the install. The device booted to the little green guy and all the text details appeared. Wiping cache, etc., but when the zip installed, it failed with a Status 7 error, failed to mount /system/ errors such as fonts, device or resource busy, /system/app/ApplicationProvider.apk "Read only file system".
I saved the report log, it is very informative down at the end, last paragraph gives all the juicy details. I should publish this log if I want real help. Let me do it now. Yeah, here ya go:
http://home.comcast.net/~theohmster/text/cwm_fail.txt
Oh, I can attach it! The original CWM recovery.log is attached as a txt file. Duh! :silly:
Look at the last page of the attached log. I understand Linux so I actually know what all these errors mean. Read only files means that the installer does not have root permission. Resource busy means an open file. Can't find /sd-ext in /etc/fstab, now that is a good one, there is no fstab in the /etc/ directory, not even on the phone. But why they are occurring is out of my grasp as I am not a ROM developer and android OS is not Linux, exactly. ...ugh!
Why? I mean, I do not know what to do about this. I tried this several times, first time was a total failure, the MD5 was off by a mile, downloaded it again, got a good copy, could view in Winzip, MD5 matched, but this failure. I did this several times, thank God I had chose the backup first option in CWM and was able to restore the system in short order. The entire process took about ½ hour or less. Am I doing this wrong? I tried to understand cmenard's instructions and I don't quite understand what he is saying to do. The instructions are simple. Here is the URL to the download and instruction page:
http://forum.xda-developers.com/showthread.php?t=1892046
But, it fails by my method, what do these instructions mean in plain English? Flash Rom, what do you mean "flash the Rom"? I got two zip files, gapps and milestone. What is this "Rom" to flash? Wipe I can do in CWM. Flash the zip. You mean install with CWM? Wipe the cache. Again? How? Run CWM again?
Flash Rom in CWM or TWRP
Wipe data/factory reset if you are coming from another ROM
Flash the zip
Wipe cache/dalvik cache
Then flash GApps.
Reboot
So like what am I doing wrong? I really want this Jellybean, especially for my Razr Maxx, but if it will not work on the tablet, I will not mess with my rooted 4.0.4 Razr where I really want JB. The phone was pretty fast 6 months ago, but it seems that all these updates and apps have slowed the thing to a crawl. I use Micro CPU Monitor and love it, two single pixel wide green lines at top screen, one for each core. They are often both pinned all the time so the phone is slow. Use it on the tablet too, same issue but nowhere near as bad on the tablet as it is on the phone. Like who wants to wait 60 seconds every time you touch the screen to make a call or use the maps? Jellybean is said to make things a LOT smoother and really grease the wheels to make ICS really slick and that would help, yes?
I showed the log to a developer on droidxforums, he is really good and made the CD iso files that boot the PC to Linux and rooted the phone. But he really was not sure of the issue and does not have this device.
Somebody help me please. I really want to fix this and am really bummed. Thanks. Happy New Year. :crying:

AFAIK these are fine.
EDIT: The datadata one is questionable though.. that might be a typo somewhere (maybe... not totally sure. I know there's a /data/data directory, maybe a missing slash? Just thinking out loud here. Whatever it is, I doubt that this is your real problem. That would be the inability to mount /system
Couple questions/things to try.
Firstly, can you remount /system as RW in terminal emulator?
Second, can you install any custom ROMs other than CM10? Try any really, just want to see if the problem is CM10 or your device/CWM setup (Let's hope not the second one)
You do seem to be doing the CM10 install correctly from what I can see.
Oh, and thank you for having the sense to make a backup. Too many people don't and complain about bricking their device and having to ODIN to stock.

FYI, datadata is a partition symlinked to /data/data, it is only present on some devices like my Fascinate where /data/data is stored on a different memory chip.
