[Q] Recovery question - Nexus 7 Q&A, Help & Troubleshooting

I rooted my device with wug's toolkit and was running TWRP. The OTA came out so i flashed back to stock, unrooted to update to JWR66Y. Now i rooted the device again and also have TWRP. Before i flashed back to stock i backed everything up with titanium backup, i created an android backup with the toolkit and i also created a nandroid backup with the toolkit. I then restored my nandroid backup with the toolkit and the OTA was not applied anymore and i was back to square one. my mistake.... what do i have to do to put everything back the way it was without it reverting back to JWR66V? I am sorta new to this and have a good general knowledge of what is going on and i just need to know what direction to go in.
thanks

I am now rooted with TWRP again... Back to stock with none of my apps but I am up to date with the OTA. Still dont know what direction to go in to restore everything as it was and keep the JWR66Y update.

If you just restore the data partition, that should give you your user apps and app data back but im unsure how well it will work restoring 4.2 data to a 4.3 os

Ok thanks alot.
I was on 4.3 JWR66V before i flashed stock and updated to JWR66Y. Should i use wug's toolkit to restore (just data, not system) or do it through titanium backup?

Id say try using the toolkit first, if it doesnt work, wipe data partition and then try using titanium backup. Another good tool is nandroid manager, i use that to restore apps and data from a CWM nandroid backup. If you put the nandroid backup from the toolkit onto your tab and then use nandroid manager and see if it will read the backup.
Good luck!

ok, i just recovered only the data from my nandroid backup with the toolkit and it seemed like everything was ok at first. I tried a few games and they worked until i tried ones that i had saved game data and realized my saved games were not saved. Also the games i had with obb files previously did not work because the obb files were gone. Another thing... all my apk's on the internal card are not there, yet the games are working. I then took the titanium backup folder that i copied to my computer with the backup and put it on the internal card and loaded titanium backup. It did not recognize the folder and it showed that i did not have anything backed up at all.
now what to do?

Update: I clicked on the batch button on titanium backup and was able to try and restore my apps and data. It did not put the apk's back on the internal card or allow me to play my saved games.... I also tried just to restore the Andoid backup using the tookit and that didnt bring anything back either.
I flashed the stock recovery and unrooted with the toolkit to undo everything i just did. I then rooted the device and added TWRP using the toolkit. Now i am rooted with none of my previous apps or saved games, but i am updated to JWR66Y.
Hopefully someone can help me restore all my apps and saved games because what ive done isnt working.

I really dont want to put all the apk's and reinstall all my games and apps back on my nexus. Someone must have some insight please.
thanks

Hi, flyers27...
Sorry to read about your difficulties restoring you tablet back to it's pre-4.3 glory.
Unfortunately, there are no easy shortcuts to getting all your apps back the way they where. You're going to have to use Titanium... your NANDROIDs from 4.2.2 won't really help you...
If you have Titanium backups of your apps on your Nexus 7 (by default they're located in /storage/emulated/0/TitaniumBackup), then it's just a case of going through each listed app backup and selecting either (from the Backup/Restore tab) Restore App only or Restore App+Data.
Personally, I only ever use Batch for backing up apps, preferring a more discretionary approach to the apps I restore, and whether or not I choose to restore a given apps associated data. It is, I grant, a bit of a slog, but it's not a task that's going to crop up everyday... it's just a once-in-while-sort-of-thing.
----------------------------------------------------------
Up until Jellybean 4.3 was released a few weeks ago, I'd been happily running a Jellybean 4.2.2 based custom ROM/Kernel combo for six months or so, and I knew if I wanted to avail myself of Jellybean 4.3, I had to wipe the metaphorical slate clean and begin anew.
Here is what I did...
----------------------------------------------------------
1). Performed a NANDROID backup of my (then) 4.2.2 based Custom ROM/Kernel combo. This was more for insurance sake, so should anything go wrong, I could easily get a working system back, relatively quickly. But if everything went according to plan (which it did), that NANDROID backup would be essentially redundant (which it was).
2). Performed a full Titanium backup of all my 150+ user installed apps.
3). Copied EVERYTHING off of my Nexus 7, to my laptop. (NANDROIDs, Titanium backups, Videos, Music, Documents, Images, etc., et.al.)
4). Fastboot flashed Jellybean 4.3 (build JWR66V). Which, also wiped the tablet.
5). Fastboot flashed TWRP and Rooted.
6). Copied EVERYHING (except the NANDROID), back to my Nexus 7. (Titanium backups, Videos, Music, Documents, Images, etc., et.al.)
7). Set about the business of selectively restoring my Titanium backed-up apps.
----------------------------------------------------------
I had the whole thing done in slightly less than 2 hours. Upgraded from 4.2.2 custom to 4.3 stock... and rooted.
Sometimes there are no easy ways; you've just gotta bite the bullet, and get it done. And none of this is technically difficult, it's just a bit tedious.
In your case, it shouldn't take that long... if you have your Titanium backups on your Nexus 7, just restore what you want FOR NOW... and perhaps maybe come back to those less urgent apps at a later date. Not everything has to be restored immediately. The difference between TWRP/CWM NANDROIDS and Titanium, is the former is Monolithic (the restore is all or nothing), but the latter is Granular (you can cherry pick from Titanium).
Anyway... just my thoughts. Hope it helps.

Ged.

Compete Android OS Image restoration / backup?

Hey all,
When I had my Windows mobile phone, I could use Sprite Backup to make a backup that basically acted as an image that I could store on the SD Card. I could then do anything possible to my phone, and then I could simply restore the image, and it went back to the EXACT state it was when i took the image - registry, ALL apps, messages, icons, etc..., just like a 100% hard drive image.
I have Sprite backup on my Samsung Epic now, and was wondering if it acted the same way?
That is, if I install a custom rom, I would like to be able to factory restore it, then apply the backup to take it back to the exact state it was.
Is this how it works?
Thanks,
Matt!
It's called a nand backup and one of the benefits of rooting

Great,
I'm rooted, so I'll. Check it out....
Thanks!
Get the one click root and recovery. Once you have clockwork mod you can do a full backup. Also you can do an "advanced restore" and just restore your /data.
I have found that sometimes a restore doesn't work correctly and I have to reflash the rom and just restore /data to put my apps and settings back.
A word of warning, sometimes when you flash an old /data to a new rom it causes issues with programs. Personally, I have had very few issues doing it, even when moving between 2.1 and 2.2.1, but ymmv.

[Q] A few random questions about cwm, backup etc

I have successfully rooted my device using the version 2.0.0 of the toolkit. I think I'm going to donate a few euros to get the latest, the author deserves all the money.
A few questions:
What exactly is CWM? What's the difference between a backup made with titanium backup and a backup made with CWM? Is it enough to backup the system settings or do I need to backup even the apps? I mean the list of installed and purchased apps should be always available on the Google play account, at least I hope so...
Should I download the latest version of CWM (the . IMG file) and flash it with the toolkit or should I use the integrated version that seems to be IN the toolkit?
Thanks in advance for the answers.
A CWM backup will backup everything. If you restore it, your device will be exactly the same as it was when the backup was made.
Titanium backup only backs up apps and their data
But with titanium backup do I need to backup all the or only their data?
Is CWM useful even to install other Roms?
Sorry for the confusion: I'm not an expert.
Clock work mod will backup your entire android build as it is. all data, apps, settings, contacts, messages. etc
Titanium will backup apps and their data only
If you bork your software or try another rom then decide you want to go back, a Cwm backup will take you right back to the exact point you made the backup
Titanium is useful to have when changing roms because after loading a new one you can load your previous apps & data into your new rom whereas Cwm would completely overwrite the rom
In essence they are similar but perform completely different tasks
Sent from my Nexus 7
With titanium I usually just backup all user apps with data (meaning anything you have downloaded that is not part of the rom)
You cannot flash a new rom with titanium. that is what Cwm is for
Cwm deals with the roms
Titanium deals with apps

CWM is a recovery mod used for Flashing new rom while at the same time gives you handy things to do like, do a NANDROID- Creating a image for ur current rom and all its sys settings with apps and there data. U can also Flash other things like a previously created Update.zip for Titanium Backup, which is helpful after u have flashed a new rom and want all ur previous apps and data back.
A small thing a consider sharing, When Flashing a new ROM, Back up only the apps+data thing and not the System. As ur new ROM will have its own System settings (better to adjust it then than bfore). Now, also Create an update.zip, which a mentioned earlier from TitBckp Menu.
Have Fun.

I still don't get the point of backing up apps. I mean: their settings (and system settings) ok but why backup something that can be downloaded again from google play store? I guess my account keeps record of my installed and (above all) purchased apps (tapatalk only). Am I wrong?
Other question:
I'm using the stock Jelly Bean 4.1.1 rooted and I don't want to mess with cooked roms whatsoever. I rooted the device in order to get USB on the go support and TiBackup.
Will I get updates from google or I will have to manually flash a rooted version of an updated Rom? I think I will have to install CWM at the end, I guess

So, in my condition (rooted stock rom) will I get the official google updates without doing anything?
You will still get the updates but Cwm will not be able to install them.
You would need the stock recovery to apply ota updates
In reference to your previous question regarding titanium. You could re download the apps from play store after a wipe.
Titanium also restores any preferences you had saved. And in the case of games it will also restore your progress & game saves
Sent from my Nexus 7
Thanks, so there's no point in backing up the whole app, we only need its data and settings.
I haven't installed cwm yet. Did you use the toolkit downloadable from another thread in this forum? If yes, does the toolkit automatically download the latest version of cwm?
I'm not sure with the tooolkits
I have never rated them
It's much wiser to learn to do these things manually as it really doesn't take very much learning and it's always valuable to know what to do in case you bork something

Does cwm also backup sripts like link2sd and 2nd fat32 partition?

[Q] Downgrade from 4.2 to 4.1.2

Some apps not working after updated to 4.2, so I'm considering back to 4.1.2.
Though I never done this before since the day I get Nexus 7,
I think use Wug's Nexus Root Toolkit should get it done.
But just for sure:
1. Do I need to unlock/root to flash factory 4.1.2 image? (I think it is not but not so sure)
2. Directory structure seems different from 4.1.2, is it OK just using Toolkit to backup/restore settings?
(Sorry for my English if anything looks impolite)
1) unlock bootloader yes; root no, as you're going to overwrite the system anyways.
Also I'd suggest not using a toolkit, just download the factory image off google's page and run the "flash-all.bat"
2) Use Titanium Backup to backup all app data, wipe after flashing 4.1.2 and then restore apps + data with Titanium again
I just downgraded this morning. All your data will be wiped .. ALL YOUR DATA ... meaning, after I got back to 4.1.2 I was having 13GB of free space on the tablet (out of 13 possible) .
So, if you HAVE a nandroid from the 4.1.2 days, save it to your computer (along with all your files).
If you don't have a 4.1.2 nandroid, at least create now a backup repository with whatever tool you prefer and then save the respective files to PC.
Then, flash the factory image for 4.1.2.
Then copy all your files back to the internal memory, install the backup tool and restore your apps.
The reason behind this is that the update from 4.1.2 to 4.2 has some scripts that are porting the original /data and /sdcard mounts to the new structure used in 4.2
When downgrading, you no longer have scripts to do that for you so the newly installed 4.1.2 will not recognize anything so it will bootloop like crazy (I tried first to restore just the /system ... but all the other data was already affected by the update so was no longer usable).
My thoughts:
If you got the ota, and things messed up, try flashing the 4.2 factory image. That seemed to help me. If you're not rooted already, I would recommend becoming familiar with the adb backup command to backup apps before doing anything else. You have to unlock the boot loader to downgrade or flash the factory 4.2 image, and this will wipe the device.
Once you update either way, definitely take the time to root. You can then use adb restore or titanium backup to restore from the adb backup you made before unlocking.
Just be aware that adb backup doesn't seem to backup all apps, and that titanium backup isn't exactly fast parsing through a big adb backup file.

Assumed you are referring to downgrade from 4.2.1 to 4.1.2 and rooted to run TB, so the basic stock rom is up & running otherwise, correct?
Let's try Plan B instead - go into (Custom) Recovery and wipe dalvik cache first, then reboot. Give it a few minutes to settle and try to do your TB restore WITHOUT data, and see if it works. The /SD and/or /SD/0 directory structures are setup differently on the N7 and trying to retore with your custom settings will just make it more difficult & complicated. If this works, you can then try to selectively restore one or more with data and hopefully without going into endless bootloop again.
Plan C - go to Play Store, then Settings and "All" - you should see all of your Apps and what's installed, etc. - and install from there, it's semi-manual but it works for me 99.8% of the time when it would otherwise freeze within TB, especially true when switching custom Rom & kernels.
I usually manually copy & move back items such as documents, pictures & mp3's, etc. from standalone/usb backup drives or cloud storage back into the device once everything else are up & running properly.
Let us know if this helps & working for you or not.
Thankss !

Thanks for your help , but I think the problem was that there were apps in the backup only compatible with the custom ROM I had and android 4.2.1 xD
I restored the apps one by one , but I think if I deleted the extra custom rom apps , the process would have finished without any problems
Hi fellow people,
i'm a noob just made my xda account like 5 mins ago. I've been trying to search for my problem but I haven't really a found a direct answer. So yesterday I just got my Samsung Galaxy nexus update to 4.2.1. I was really excited until I started having the battery issues, screen lock issues, and overheating problem. I really don't like 4.2.1 and want to downgrade my version back 4.1.2. My carrier is the Mobicility (Canadian). I did not do anything previously with this phone such as rooting it, doing all the funky stuff that will void my warranty. I heard about flashing some google images to get back 4.1.2 but I'm not sure if I need to root or how to like do it through the gnex toolkit that mskip made. As well what if the difference between yakju and maguro? I heard if you flash the wrong image it will brick your phone or something like that. If there is a method without having to root it and lose all my contacts, then I would prefer that a lot.
Thanks,

You dont have to root but you need to UNLOCK the bootloader which will obviously erase all your data(and VOID your warranty). you can find the factory image here https://developers.google.com/android/nexus/images . just flash the appropriate image and you should be as good to go.

[Q] Smooth Rom 4.4

Hi
As you've prob guessed I'm a noob, hence the help.
Ive just recently rooted and unlocked my nexus 7 with wugfresh 1.6.2 and am now looking at putting a custom rom on it.
Ive followed the advice and put titanium backup on and backed up my apps and system data.
Having read the instructions for installing Smooth Rom 4.4, it states 'Please do not restore a 'system' data backup as it would overwritte some important files'
does this mean I cannot restore my apps from titanium backup as I cant restore system data as they where backed up together or is there some other way for me to do it ?
does titanium backup get wiped as well ?
All Help appreciated, this is my first rom install and I dont wanna **** it up.

The most important thing to do is to make a FULL nandroid backup before you begin.
The 2nd most important thing to do is to get that backup copied someplace else besides the tablet. (PC, USB key, etc) Screw-ups involving accidental erasure of the psuedo- SD card area on the tablet are commonplace with folks that are new to this. It won't do you any good to make a backup if you immediately erase it while fooling around with a custom recovery (or toolkit) that is new to you.
I suggest you learn to make backups using the custom recovery rather than relying on a toolkit.
If you are happy with the tablet in it's current configuration, then a back-up allows you to survive any ****-ups that inevitably follow as you can return back to a known state and proceed again having learned from your mistakes.
FULL NANDROID BACKUPS. COPIED SOMEPLACE SAFE (OFF THE TABLET)
As for TiB, the only thing that is 100% safe is to only restore apps & their data that are NOT pre-installed in whatever ROM you are installing. Note this means not restoring any of the Google gapps as well, as you may have had a different versions of those apps running on your current ROM than on the to-be-installed ROM, whether pre-installed or updated later.
Yeah it's a bit of work restoring apps one by one and re-configuring things. There probably are System apps that can have their data safely restored to the wrong version of the app - but there are absolutely no guarantees that correct operation of the app will follow that.
cheers and good luck

HELP - Restoring backups to a new custom rom

SOLVED!

I have been scouring the internet for over 2 hours, and I can't seem to find anyone who has done something similar to this, so here goes:
I currently have a Nexus 6P with the Pure Nexus Project Rom installed. I would like to switch to CyanogenMod. Normally, this would be no problem, however I am running into some difficulties with backups. Ideally, I would just do a NANDroid backup from TWRP, but I don't have enough space on my device. Right now I am running a full ADB backup to my computer, but in this instance I don't know if I'll be able to restore that backup to a new CyanogenMod installation.
TL;DR: Will an ADB backup restore to a new custom rom i.e. restore to CM from PureNexus? If not, is there a way to do a NANDroid backup directly to my computer?

You shouldn't be using TWRP to backup/restore data between different ROMs in the first place. That will not only back up your apps but all settings as well, which will cause problems on a different ROM. The only safe way is to use Titanium Backup to backup your user apps (not system apps) and then restore that backup on the new ROM.

Well that goes against everything I've seen... Thanks though.

Could you point me to where you've seen someone recommending to restore a nandroid /data backup on a different ROM? It's widely known that this is nothing but trouble, if it's on XDA it probably needs to be taken care of.

Titanium backup is the only really viable solution in such a case. When you need to make a snapshot of your whole system in case of failure you use a Nandroid backup, however when you need to transfer data between /system formats then it's best if you use titanium backup.
