I've already rooted and unlocked my bootloader and I'm just about to load a custom ROM, however where do I put the files so when I wipe/factory reset they don't get deleted? Thanks.
Your files don't get deleted. Only data and apps on android partition

Anywhere outside /system. i.e. place them on the part of your sd card where your pics, music, etc... live.
Really? That doesn't seem right for some reason...I just unlocked & rooted my girlfriends new Verizon Nexus but didn't put a ROM on it right then (which I should have done ), and during that process all of her photos and apps were deleted. I luckily had backed up photos, sms backups, etc. off of the device so I was able to transfer those back, but it was bone stock (like nothing on it at all) after that process. Is that "wipe" different than the "wipe data/factory reset" we have to do before going onto most of the ROMs for the Nexus?
Sorry about my ignorance...I'm an Epic 4g Touch owner so I'm well versed in it, but just starting to learn about the Verizon Nexus. Thanks a lot guys.
Unlocking the bootloader wipes it all; but a wipe data/factory reset from CWM doesn't touch your virtual sd card, i.e. photos, etc... remain. The OP is already unlocked, so he's "safe".
I will answer your specific question, "Where to put files so a wipe won't delete them?" If you want to be safe, on your computer or on anything external other than the phone. I only say this because the phone does not have an external sd card. Ill repeat what I said in another thread...we don't backup for the disasters we foresee but for the ones we don't.
Only the factory recovery wipes the /data/media ("/sdcard") partition. Any third-party community-built recovery (like ClockworkMod Recovery or TeamWin Recovery Project) will wipe everything except /data/media.
So, to answer your question, as long as the files are on your phone's pretend SD card (the default for user-created content and files you transfer to your phone), they won't be wiped when installing a custom ROM.

Awesome - thank you both for your responses. That's actually a pretty cool little feature. I wish my phone could have apps retained after doing a "data/factory reset" wipe, which is such a good idea when going between ROMS.
I am stating that correctly, right? Apps, app data/caches, pretty much everything but system apps will be retained after a 3rd party data wipe? I just want to be sure, especially since it's not my device I'd be messing with Thanks

No, I'm afraid not. Applications will be wiped, as they reside on /data/app. The only item not wiped is the /data/media partition. Plug your phone up to your computer - the files and folders that you see listed will remain after a full wipe. Everything else will be gone.
Though, to be technical, a "factory reset" wipe primarily wipes /data (except for /data/media) and /cache. You'll generally have to manually wipe (through recovery) /system.

Yeah, that's what I was thinking...thought it was a little too good to be true. No biggie...that's what Titanium backup is for
So, just to play devils advocate...if I were to copy, for instance, the go sms backup file that's created when you backup files to the /data/media partition, theoretically that would be retained, correct? That's about the only thing that would be lost doing a 3rd party wipe that couldn't be TB restored...and when I talk about the go sms back up I would like to throw things like her circle launcher setup backup files, etc. in that ring...what do you think about that?

A lot of apps (I can't speak specifically for those, unfortunately) actually keep their user-created backup files in a directory on /data/media, so those would be safe. I know that Nova Launcher, Titanium Backup, Tasker, and some others do that.
The SD card does not get wiped between rom flashes using Cwm. Only the first boot loader unlock does everything get wiped.
So all my files and pics on my SD card stay in tact when I wipe in Cwm or flash a new rom.
Hi all,
I have a similar question.. I'm wanting to know where I can safely put the ROM zip because I want to wipe the sdcard0 partitiion
If I put it in /data/media I should be able to select it from there in CWM recovery right?

So I rebooted into recovery, formatted the sdcard.
Now when I try to push the file in adb, it's not showing up.
Tried pushing to both /storage/sdcard0 and /sdcard but they're not showing up when i ls into them from shell. In fact I can't acces /sdcard at all, but /storage/sdcard0 is empty.
I can't mount /sdcard in CWM either.
Help!

Try /data/media, as that is where the "sdcard" data actually resides. The other locations are just links that point here
You may need to use the recovery option to mount /data.

I ended up flashing back to stock and then flashed a new ROM and it seems to be working OK.
In the future, though, what should I have done different to avoid not being able to access /sdcard?

Acer Iconia A100 Tab, ICS, rooted, unlocked, backed up, CWM, Superuser.
The A100 comes from the factory with 8GB internal memory and I added a 32GB chip. Fine, but as expected, I soon got the dreaded "Insufficient memory available" message. The A100 has an inherent design flaw which does NOT allow apps to be transferred to SD (have tried everything).
I've successfully swapped the mount points and now have combined the internal 8GB and the external 32GB to act as one single drive. The machine now sees itself as having 40GB of internal storage. Works perfectly BUT...
...now I'm permanently getting the ol' "Insufficient storage available" message on EVERY app I try to install. Even worse - I've done massive uninstalling of almost ALL my programs, and now I can't re-install ANY apps with getting the insufficient storage message, either from Play Store, or as a standalone apk installer file.
I've tried;
- Lucky Patcher
- rebooted countless times
- set all system files and folders to RW
- every type of cache cleaning program
- increased my swap filesize to maximum
- every type of past-program-cleanup tidy program
- tested, verfified, but still replaced, the 32GB sd chip
- used a terminal emulator to properly rewipe the cache folder
- restricted the list or startup programs to only system-required apps
- using SDK, have tried both the "set install apps to internal" and external drives
There is very little left on my system now (95% free), and the system runs beautifully and passes all diagnostics. I've just reached the point now where I cannot install or reinstall even the tiniest tiny programs. Of the few remaining programs, I dare not uninstall CWM, Superuser or ADB Control, for fear of not being able to even restore past backups.
In short, the more capacity I give back to the system, the less capacity it has.
Any thoughts/suggestions? (other than using it as a doorstop)
IF you have GPS enabled, look for the GPS data files (I can't remember exactly where) as the GPS on some of these tablets (like mine) repeatedly download AGPS data at will filling up part of the memory. Not sure if this is your issue, but this caused me all kinds of insufficient memory problems with my A100.
Yup, check the /data/GPS folder. If you use GPS it gets loaded with dated .txt cache files. The only fix is deleting them every once and a while or factory reset if your not rooted,

Thanks for your input. Yes, by this point I've ended up with a long checklist of regular things to do just to take any argument away from the machine. I regularly clear the data from Play Store and Frameworks. The GPS has been disabled for weeks, and was set to not update from any source other than straight GPS satellites (non-network). I killed off the few GPS data files I did find.
The available storage is now down to 382mb, and seems to be dropping by 50mb per day - while it simultaneously tells me I have 28GB free! WTF?
I now only have about 7 programs installed, excluding the obvious factory preinstalled ones.
CWM - 384kb
ES File Explorer - 5.7mb
Android Assistant - 1.74mb
Acer Recovery Installer - 2.55mb
Lucky Patcher - 5.62mb
ROM Manager - 5.32mb
Link2SD - 0.94mb
Wake Lock - 72kb
If I uninstall any of these in the vein hope of trying to clear any more space, I won't be able to put them back. Everytime I boot, I get the "Low space" warning, and no apps can be installed at all.
Just a thought - under Data Usage > Removed Apps > it shows an ever-climbing graph, and says Foreground: 0.00B, Background 2.70GB Is this just a record of past activity? Or does it show actual space that's being consumed? If so, I can see no way of clearing it. The View app settings button is greyed out.
I was having a similar problem although I never figured out what was the deal I used pio's black hole wipe and reinstalled my rom and everything works great now.

I was going to mention that app tends to cause that error, its come up before. Any further discussion concerning that app should be taken to PM or off forum completely.
I would suggest the black hole wipe or at least a hard reset and leave that app out of the next install. No restores just fresh installs from play store.

Lucky Patcher was the last app I was successfully able to install a few days ago, and I only put it on in a last ditch effort to try and solve the 'insufficient memory available' problem which had been growing steadily worse over the past two weeks.
I did a hard reset and confirmed a clean running virginal machine, although I still got the 'Low space' and 'Insufficient memory available' message, but I did a another backup just to be safe. I then followed the black hole wipe to the letter. Everything went smoothly through each step, and now when the phone boots, it just sits there displaying the Acer logo for eternity.
When I do a recovery boot, I can now only get

Does anyone know if there's anything that can be tried first, before I send it back to Acer?

All of which is not necessarily to be feared - as long as you can still gain access to the recovery ROMs on the external SD. The problem is, after doing the above-mentioned processes, you cannot even boot into recovery, much less access the external SD. All you're left with is the Acer logo, and the ability to power up or down.

Wow! That's good news! (maybe) So... if I can unlock the bootloader then, in theory, I should be able to continue restoring the tab? Please excuse my vertical learning curve on this. If I understand correctly, there is no bootloader unlocker for the A100 iteself, but apparently there's a compatible one for the A200 that can be used.
From my tab's current state, could you please tell me what the next step(s) are?
I'd be eternally indebted to you.

In Windows, we can format the whole hard drive and install a new fresh system. Can we do the same to our Samsung Galaxy S3 - fully format the HD clean and install ROM back?
I test out many JB ROMs, Kernels, & apps - now my phone is full of mess. My phone starts to have many problems, force closes and freezes.
My T-mo S3's IMEI was loss (w/o any backup) - so I injected IMEI back but the data kept trapped in EDGE and suffered constant low signal.
How can I restore my phone to the original condition without any previous traces or residual file?
Greatly appreciate for your help in advance.

Not sure if that super wipe is compatible with our phones, though. I'd format system/data/cache and wipe sdcard (internal) and just flash something else before I'd try something that hasn't been tested on our devices.
Thanks theexel. My phone has so many useless files all over the place - I want to do some house cleaning and get a fresh start. I have been doing "format system/data/cache and wipe sdcard (internal)" every time I flash. Just want to get back to once it was - everything is clean & well structured.

You can't really compare a windows partition to an android ROM. Windows stores everything, data, system files, etc on the same partition. Not only that, but when a Windows program installs itself, it copies files to system directories throughout the drive and to the registry.
When you uninstall a Windows program, it's very possible that not all of those files and registry entries are deleted, which is why the drive gets cluttered and needs "spring cleaning" every once in a while.
Android works differently. It has separate partitions for System files and Data files. If you don't manually mess with anything in the /system partition, then it should still be the same as what came with whatever ROM you most recently installed. Any apps or data on your phone is stored in the /data partition only.
If you think your phone needs to be started over from scratch, then the best thing to do is delete the /system partition and the /data partition and reinstall whatever ROM you want to use. The Kernel will automatically be erased and reinstalled whenever you install a new ROM. Anything beyond /system and /data is overkill because all the other stuff gets erased automatically anyway when you install a new ROM.
Good luck.
1. What is the difference between the following terms: adb. fastboot, bootloader, recovery.
I understood a bit from efrant's thread but I still need some more clarity.
Correct me if I'm wrong - ADB is a mode which can be accessed by either booting into recovery or booting normally into android. and FASTBOOT is a mode which can be accessed by booting into the bootloader.
A key question still remains in my mind - what is the difference between booting into bootloader and booting into recovery?
2. How do I open command prompt in a specific folder? The instructions listed in efrant's thread don't work in Windows 7.
3. I can flash PA as long as I have an unlocked bootloader even if device is not unrooted?
4. Where do I get the fastboot.exe file and adb files (the .exe and two .dll files for Windows) being talked about in efrant's thread and what are they used for?

1. The bootloader is Google's interface for flashing the phone with stock images. Recovery (stock) is used to flash OTAs & perform a Factory reset.
3. You need a custom recovery (either TWRP or CWM) to flash a custom ROM, your phone does not need to be rooted.
4. Look for efrant's (stickied) return to stock thread in the general section, it has the needed fastboot & adb files attached to the OP.
5. Yes & they also generally include a kernel (some have a stock kernel some use a custom)
6. AFAIK Chainfire's SuperSU is more reliable ATM on Jelly Bean.

That's the link I used to set up adb. Just make sure you get the nexus drivers set up right. To test it when you think you've got it all set up, make sure you have adb debugging checked in developer options, plug your phone in, open command prompt and type adb devices. It should spit out a line of numbers. If it's blank that means the phone drivers aren't set up right. If you want to test it further you can try an adb push command.

I am on CM10.1 and the backup I made with CWM was stored in data/media/clockworkmod/backup. Its an odd location but I have done factory resets in order to install other ROMs and the backup remains. And a factory reset does not wipe the Internal storage. A factory reset pretty much just resets the system files back to stock. The only thing you really lose is your apps. All your personal files (pictures/videos/etc.) are left alone.

Factory reset wipes /data (where all your play store/side loaded apps and data (app settings, etc) are stored)
and /cache
it does not touch the /data/media which is your internal storage. since there is no external storage on the nexus, there is nothing to worry about there
/system does not get touched unless you flash a new rom or wipe it manually from recovery
if you wipe /system, you better have another rom to flash in its place....or the phone wont boot into the OS, because /system contains the OS

There's an option in twrp at least, that allows to format the internal storage. if you do it by accident or need a fresh start/don't care about the data, of course you'll need to know how to use adb to push stuff back to it, previously pulled from it to the PC.
What I'm saying is that it only matters as much as you care about your data stored up until that point. I keep regular, tarball backups of /data/media in my PC.

So, Nandroid backs up all 13 partitions?
Note: nandroid backups get created on /sdcard aka /data/media.

What is this /data/media that you talk about?
I read that Nandroid backup gets stored on /sdcard/clockworkmod/backup
Edit: Also, http://www.vikitech.com/10347/perform-nandroid-backup-restore-android-device says "A point to note here is that your SD Card data is not backed up."

The backup will be in either location. Some phones put it on the sd card. I just recently got a Nexus and found out it was backed up to data/media/clcockworkmod/backup. To get to that location, you need a root browser. I use Root Explorer and love it. Once you get one, you can go to the root directory of your phone and start going into each folder data/media/clockworkmod/backup.
/data/media/ is the same as /sdcard/
You must backup your own sdcard. Adb push /data/media to a computer
Using TWRP 2.6.3.0, I'm unable to wipe data. Every time I try, I get
"wiping data without wiping /data/media
E: error opening '/data/lost+found'
done."
I excluded the nonessential bits, if anyone wants a full log (something something partition details), I can make one.
I using ES File Explorer with root explorer on, I checked out /data and found two lost+found folders, which I think is causing my issue. I've tried deleting just one, but a second one is automatically generated. If I delete them both, then they're automatically recreated as well. If I delete them both and then remake one immediately after, another one will be remade.
I also checked the rest of the /data folder, and I did not find any lost+found files, so I'm pretty sure it's just the folders messing things up
I checked this thread, but I didn't find anything useful

I ended up here after I accidentally wiped my internal storage with TWRP. I went from a 4.3 AOSP rom to 4.1.2 stock (HD RLS16). I wiped the 4.3 rom, but I think I accidentally wiped internal storage then as well, or maybe something was messed up with TWRP because the storage folder for 4.3 isn't in data/media (or at least not for the rom I was using). After that I used hyperdrive, which was super buggy with Gapps and didn't work at all. After adding an account, everything kept force closing, and things were extremely slow and took minutes to open, even after removing the account and wiping cache+dalvik.
I thought it had to do with the rom, so I went and wiped stuff, then went to CM 10.1.3 stable, but that didn't boot at all, so I tried wiping again and going to liquidsmooth 2.9, which is where my problems started again. I attempted to wipe again and go back to cm10.1.3. The wipe failed, but cm10.1.3 worked.
any ideas on how I can fix this? I was unable to find help on google.

Anytime you get that error format data (the one where you type yes) the folder gets corrupted and a format fixes it.

This has happened to me twice and the only solution i have found was to wipe internal storage. unfortunately i wasnt able to backup my internal storage before wiping so eveything i had on my phone was erased. Everything in your external is safe you dont have to worry but if you had important files or anything that you wouldnt erase on your internal storage then that is very unfortunate.
As for me, i now backup everything maybe like once a month or so, just in case something like this happens again.
Its happened to me also and I could not resolve it without the wipe, that was the only viable solution that worked for me.

Although if you're using twrp I just found out you can still save some of your precious files.
How? Simple
You can go into recovery and into the file manager. I think it's in settings or advanced I'm not sure. But I know that is built into twrp. So then just go into your internal storage and select the files and move them to the external storage.
If it's your first time using the file manager then you'll have to get used to it because it's not 100% noob friendly
And remember the bigger the file the longer it'll take to move so just be patient.
Use AromaFM!
search bar will serve you..
