Data when installing a new rom - Nexus 7 Q&A, Help & Troubleshooting

Hi folks !
My question can sound stupid but I use to store my data ( video, music,...) in an SD card when using my HTC desire.
With the N7 no such things...
So I would like to know if my data aren't gonna be delete if I flash a new ROM on the N7?
Thanks all sry for that easy question

Hi I am a newbie when it comes to these things, but as far as I understand you lose everything when you unlock and root your device.
For example I have downloaded a few apps and put some of my music and a couple of videos I want to watch onto my nexus. If I now unlock and root it I will have to download the apps again from the play store and set them up again with my preferences as these would have been lost during the root/unlock process. Then I will need to connect the Nexus7 to my PC and transfer the music and video files onto the nexus again. So you need to set aside a couple of hours to do this, obviously the time it takes depends on how many files you are transfering and how many apps you have to restore.
After your device is rooted you can use the app of your choice for backing everything up. I would use Titanium Backup, but that's my choice! That's why its best to root your device straight away so you don't have the hassle of re loading everything

Not asking for that but thx thought. I'm already root I want flash a new ROM

Are you using TWRP or CWM to flash?
In either case, you don't need to do a full wipe, just a factory reset (I use TWRP) is enough. It doesn't clear the folders of your media.

Using CWM ,Yo OK THX dude so I can flash a new ROM for example paranoid and only loose my apps ? Not all the other stuff right ?

Sorry misunderstood the original question

I hate having to restore

Does anyone else find it very time consuming to have to reinstall all of your data after every rom wipe? I find my self never leaving a rom for awhile because of the whole set up process including the Google set up.
It takes me an hour.

This is why Titanium Backup and Mybackup Root were written...
Titanium backup does all of that for you.... 20 minutes and your new ROM is setup

I suppose Ti is best, but I haven't seen a ics friendly one available on the open seas
Nandroid? I only have 1 one my phone and thats 2.3.3 stock.
They take long to make, then they just sit there wasting space. Its not like you can just go back to them lime nothing, because by that time they'll be outdated.

Titanium is definitely ics friendly. If you have pro (or on free.. idk), set up filters with your must have apps. When you clear data ans flash a new rom, it will verify your TB account and restore settings, including filters. Just toggle the filter and do a batch restore. I was in the same boat you were til I started doing this.
And yes, TB also has a feature to restore apps or data, extracting from a nandroid backup.

Or you could use es file explorer. Just go to the app manager button on the central screen, by pressing it it shows up all ur apps. Choose which ones you want and back them up. After flashing just restore using file explorer in the same manner...
The apps can also be found on the sdcard under backups/apps.
Astrofile manager does exactly the same job.. your pick.

With Titanium Backup I can be back up and running in about 10 minutes.
Sign into Gmail
Sign into Outlook
Download TB from market
Restore apps and data
Done
Does anyone partition using cmw? I think its possible to some how do that, like save Ti as the drive, so all you have to do is just sign in to Google rather than having to download it.

just save a copy of a TB apk to your SD.
Thats if the custom rom that has a file explorer preloaded. If not has to download also from market
Another annoying thing Google doesn't add to OS besides a restart option is a built in file explorer

thats ridiculous:
1. im pretty sure ive noticed mine being around 6 minutes
2. they arent a waste of space since they are a back up file. i keep 3 always deleting the oldest one.
3. you CAN go back to them at anytime like nothing
4. i make mine every wednesday while im showering (which takes more then 6 minutes)

Wrong. Even the free one lets you create a flashable zip.
Moreover, you could make it build as a regular update.zip or even make it install as a system app or an user app.

Noob question...flashed phone for first time yesterday and performed a backup using titanium free. When I flash a new rom don't you usually have to wipe data first? Would this not wipe the backup from your phone?
Thanks in advance!
It stores a copy in a folder called TitaniumBackup. If you wipe the SD card (or storage for us) that is different.
It is a hassle having to reinstall an app like Chase that requires a confirmation text. TB (Pro for me) makes restoring login info, etc a snap. Worth the $.

So when I flash a new rom and wipe data, the SD card (storage) is not wiped?

Noob replying to a noob (so pardon me, if i stumble):
When flashing a new ROM, you wipe - system, dalvik cache, data and boot ( perhaps not reqd.) Wiping SD card not required when installing new ROMs, unless it's the first time, and you're putting CWR on a Nexus S... However, some developers do recommending a full SD Card wipe as well. I assume you copy the Titanium backup folders to your PC, and copy it back before restoring.. Haven't tried that yet..
---------- Post added at 11:53 PM ---------- Previous post was at 11:49 PM ----------
Probably will have to buy Pro, since it's getting to be a pain to restore my apps, with the permissions for each one...
Somehow, TiBackup doesn't seem to restore my homescreen settings, though I remember reading somewhere that it should do that as well..
Also, learnt the hardway not to try restoring Call logs and Messages when moving from a GB ROM to an ICS ROM... Boot loops with 2 ICS roms (Nexusbeam and Brainmaster's )
So, what all can you restore using TiB with your eyes closed?
I am still new to this phone, but with the Evo we had a zip file that wiped the system, data, cache, etc instead of remembering which ones to wipe. Maybe there is something like that for the Nexus?
I only restore apps, so I am not much help outside of that. With TB Pro all you have to do is click batch and restore all the apps with data automatically while you sit there and wait. I generally restore user apps only, maybe someone else can chime in with advice on restoring settings?
There is also an option to save backups on your drop box account, but I don't.
I am a flashaholic, one of the reasons I bought a used NS4G was because I was bored with the Evo. Titanium Backup (Pro) makes it fast and easy to restore apps and data when flashing new ROMs.

Can't backup my phone? Confused.

Hey guys. So I have unlocked and rooted my Nexus 7 using the root toolkit. All is well, have been running rooted apps etc. I have bought and installed ROM Toolbox Pro in order to backup my tablet (among other things), but it will not allow me to do this. When I go to make a backup of the current ROM (it is stock 4.1.1, unlocked and rooted), I get a warning that states "We failed to connect to ROM Manager".
Seems like I need ClockWorkMod Recovery installed? How do I go about putting this on the tablet? I don't need to start from scratch, i.e. unlocking and rooting all over again do I?
Sorry if this seems like a stupid question. I always managed to install custom ROMs on my Desire HD, I'm just a bit stuck here.
Also, when I persisted with the backup, disregarding the error message, the boot screen was a little dead Android with a red exclamation mark. Holding power button down allowed me to reboot the unit though.
Thanks
EDIT: Just found this guide, which, in the instructions, says to unlock and root first THEN proceed to install CWM. Would I be right to follow this guide?

Hmm I must have done something wrong. Installed CWM Recovery, tried to use ROM Manager to create a backup, it gets like 90% through then says there was an error backing up data. Now when I reboot I'm told that I'm running out of storage space? Before, I had like 2gb free, now 153mb? Have found where the backup files were saved, only ~20mb so that can't be it. Hahah this is neverending

You need to free up more space before you make your backup. Delete the backup folder AND the blobs folder. CWR now uses blobs folder for differential backups.

Most Waned update

Hi guys, I have a need for speed most wanted version 1.0.28 and there are some problems with it, i decided to update it ( game is not original ).
Is there any way to backup my progress or save them somewhere?
( I have origin account, does it save my progress online? )
tnx
Root your device
Install titanium backup from playstore(free)
Backup NfsMW
Install new update then go again to
Titanium backup and go to NFsMW
Restore DATA ONLY
or else if manually you wanna do.
Data is kept at
/root/data/data/here
^^you will find NfsMW filw there copy the folder in a secure place.
Install update ..then copy back the backed up folder at
/root/data/data/here
U can replace the existing one..then put permission as the other folders.
Thats it..now open the updates game
No technique without Rooting your phone. Sorry
-Rik[Rittik]
tnx, will try it, by the way I'm rooted
Or you could simply PURCHASE the app, replay it, and not have to worry about losing progress on future updates.

You can use titanium back to save and restore the data once you have to update installed. For that matter, carbon backup will do it for non rooted devices too.
By the app its worth it

Thanks. I just checked out the sticky on here for the new root method http://forum.xda-developers.com/showthread.php?t=2387577
Will that keep all my data?
Also I'm on AT&Ts latest MF3 build. If that makes a difference. Sorry this is the first time I have every tried rooting a phone.
Dude.. if you already find the correct thread. Why don't you ask there. I guess it will not wipe your data. At least on mine it didn't but I my contacts are stored on my gmail account. So my best advice is ask on the thread..

This doesn't format your ROM it uses your sdcard to install root So you will have to wipe your sdcard. So any pictures or other items on it you will loose when you format it.

And why are you rooting?
Can I Root without "Wipe," to recover accidentally deleted photos?
I'm on NC1.
I need to "Root" without wiping the Internal Memory.
I was using Internal Memory for photos and in a state of stupor (I assume), deleted a folder I thought I moved to my PC.
So the files are now deleted. I want to use one of the many recovery tools but thus far, all that I can find require "Root" access.
BTW: As an aside, does anyone else experience issues with copying too/from Internal Memory to a PC and the files seemingly go, or at least them are visible in Explorer, but then after disconnecting the phone, when you look for them, they are not there?

Is It Possible to Backup Files When Phone Doesn't Boot?

Hello,
I literally installed the Facebook app from Google Play on my Nexus 4 hours ago and then my phone literally went blank. Eventually my phone was turned off as there was no more battery. I charged it and powered it but it no longer boots (it has been stuck at the X screen for hours). Is it possible to backup my files despite this so I can try to reinstall a custom ROM/unroot my Nexus 4?
I spent some time searching the forums and couldn't find the answer, so any response would be helpful and appreciated. Thanks.
One of the suggestions here might help you as well:

I can. I am running on TWRP v2.3.2.3 but I don't think I can access the files through ADB as I did not set it to Development Mode (ever). It seems I can actually back it up through TWRP, but my concern is I don't know how to extract it out of my phone because once I reinstall JB everything will be wiped right?
Once I reinstall a JB version that means everything will be erased. Does anyone how to keep that backup from TWRP if you can't take it out from your phone? It appears my version doesn't seem to have Nandroid.
Also, does anyone know if it's "System" that stores all the contacts/text messages?
I want to backup my Data folder too but I only have 900mb free space left on my phone (I have the 8gb version) and my Data file is about 1.5gb. I don't remember if I have anything valuable in my Data file that I need to recover, so just to be sure, does anyone know if I can explore my "Data" folder to remove content to make it smaller so I can back it up? Thanks.
ADB via recovery should be the way to go then.
Did you try something as an ADB file manager?
See: https://github.com/sole/aafm for example.
This should allow you to copy the files to your PC without having to backing them up first on the device itself.
An alternative way would be to connect to the (ADB) shell, delete some useless files.. like music and stuff you already have (or package music as one archive - download - delete) etc. Till you have enough to package the data directory in one go. If done right the archive should preserve file permissions which is an extra plus I guess.
The way I try to make sure I don't have a problem like this is:
- Letting TitaniumBackup backup all important applications + data every night @ 4 AM when it's charging (while I am sleeping).
- Use FolderSync to sync the new backups to a server I have running. Could also be cloud of course. (Only on Wifi and while charging)
Good luck!
If you can boot into recovery it might be possible to pull data there.
Also, if you know which ROM was installed, you can try just flashing the system partition of respective ROM. It might not fix your issue but might allow you to boot and backup your data prior to completely resetting everything.
I've had something similar once. Tried all kind of solutions via recovery/fastboot/adb and only flashing a clean system image allowed me to recover important data. The phone was unusable still (constant FC's) but it allowed me to establish an adb connection and pull all data I didn't want to lose.

To be honest, I actually didn't. I decided to perform a reset and lose my data (and reinstall my ROM) as I didn't have the patience to experiment and figure it out. I just don't have time for that.
