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.

You are posting in the wrong forum.
Asus Nexus 7 is not the same thing as a Samsung Galaxy Nexus.
Ignore mmystere68's remarks.
Hello. Has anyone found a way to do this yet? I found a couple threads that dated a couple months ago with the same question but no answer. So if anyone has figured out a way to backup the apps and data on both a primary and secondary user account please help. Im pretty sure others are interested as well. I really want to try out some different roms but my brother will be really mad if I lose all his data again . Last time i backed the tablet up with wugfreshs toolkit thinking itd back up everything and when i found out it didnt after restoring i was screwed lol. Is there a way to pick what you want to restore with twrp? I know for my phone in cwm you can do an advanced restore and restore just certain things like apps and data. Is that possible for nexus 10?
I have the same problem kind of.
Have not tested but if you make nandroid backup in twrp on at least the data partition you should get all user data in the backup, right?
I however would like to make selected app backup in titanium where i could choose to include data for all or just single user. Not sure if possible.

Yes with tarp it backs up all user data. But like you I also want to backup certain apps with titanium. I hope they add this feature soon because I like changing Roms to see my favorite. I'm about to flash paranoid android and I did a full backup first. If my bro gets mad I'll just restore the backup so he can have his stuff back

Well i tried installing paranoid android. Then booted fine then i restored data via twrp and it wont boot i guess that doesnt work. Any other suggestions fir backing up multi accounts?
Sent from my LG-P970g
If anyone is interested go into super su and enable multiusers so now you have root on all accounts then just back up apps on each account with titanium backup and move then to pc (just in case) then you can flash any rom you want and restore the apps. Hurray . Its not as smooth as id like becaise wiping data wipes new accounts so you have to readd them but just back up all pics to google plus and anything else to cpu. Your apps and data from titanium backup will be backed up and now you have everything saved. So if anyone needs this it works. Took me a while to finally figure out a way with lots of nandroid restoring but now i.got it
Time to flash some roms till i find a favorite
As u can see im very happy

I am trying to do the same as you! The way you described doing it, I think you are just using Titanium backup app and not nandroid backups in the end, is that right? So you used Titanium backup all your apps and their data (but not photos/other documents/files on your tablet), and then you flashed your new custom ROM and used Titanium again to restore all apps/data in each user account separately? Sounds straightforward if I have this right! I have not done this before, so want to understand it before I do!! Thanks for your help... :good:

It's kind of annoying but it works. You have to back up the apps in each account then move it to a computer then back up the next account and move it to computer then back up the next etc... You have to do this because it erases the secondary accounts when flashing a new ROM so you lose all the backups you made. So putting it on a CPU then moving it back after the flash will make sure you have them

OK, thanks, sounds like I had described the right technique... will give it a try!
Lots of ppls here lost their efs, imei etc.. Or getting bootloop or can't make phone call wifi not working after flash a new rom or tried to do nandroid restore.....
Good news are we have so many hard working devs come up solutions to repair those problems.
But for a newbie like myself. I am waiting or looking for a ultimate backup method that has been proven working.... So I don't have to worry about flashing my phone. (I am flasholic Hahaha...) Is there one already? Or is there gonna be one soon?

Backing up your EFS is probably the biggest one, however I backed mine up and bootlooped and couldn't restore it so had to use this efs fix anyway.. So short answer, not really, Samsung phones are not mod friendly anymore, or as mod friendly as they once were.
Helium is a good choice for non-root backup and TB for root or a recovery back up (CWM offers custom backup)
Just the thread I was looking for. I'm looking for a WORKING backup solution for my rooted Note 3 but none seems to work.
I have seriously tried at least 7 different backup/restore apps (haven't tried TB as it just comes off as too much for my taste; haven't even downloaded it) and each of them have had their own issues. In the end I could never get my apps backed up to begin with, much less to attempt a restore.
Last one tried was Helium; I go through the backup process and I have no idea if the backup jobs were done. I see a black screen which eventually disappears and that's it. (this is basically the case for all the apps I've tried to run) Nonetheless I went to try and restore from Google Drive which I connected the Helium app to and I get the error "an error occurred while retrieving your app list". No backed up apps are displayed...
Is it something I am missing? Can anyone suggest a backup app besides TB that actually works, please. All I need is the Apps + AppData backed up to either Google Drive or Dropbox.
Much thanks to anyone who can help.
I use Helium and it seems to work ok but a LOT of people seem to have issues with it.
G-Cloud also works well and it saved me a lot of work when I had to do a factory reset when trying to fix the corrupted EFS partition.
Backing up the EFS seems to be less important on the Note3, once it's reformatted using the fix here it seems to sort itself out afterwards by rebuilding the info from the underlying hardware. Restoring the EFS when it breaks won't fix the problem as it's the partition itself that's damaged, not the EFS data within it.
And of course, Titanium Backup is still the king IMO.
Hi,
Tomorow or the day after I will get my Moto x pure, don't want to root it yet, I prefer to wait 2 or 3 months.
So my question is can I backup all my app and setting from my Galaxy S5 rooted with adb backup and then restore the backup without get any trouble or bootloop ?
Or do you have another idea without rooting ?
Thanks
Titanium Backup will do exactly what you want... Archive applications, app data, and settings from your old phone, and allow you to restore those into your new phone. The catch is that you DO need root.
You can't use adb or nandroid backups like you were thinking, because you are moving those files to different hardware. Nandroid backups only work when you are moving to the same hardware (e.g. you received a new replacement phone because your old phone got damaged, and you want to move over all of your data and settings).
If you are familiar with computers, Titanium Backup is like running a backup program (for tape backups). Nandroid is like doing a drive image. A Nandroid (drive image) will capture and restore a lot more data that a backup program, and will be easier to restore. But it only works if you are restoring to exactly the same hardware.
If you are considering root, I actually recommend you just do it on day 1. Getting root (and unlocked bootloader) on this phone will wipe your device. So you might as well do it when your phone is unused. Plus, you get the benefits of root on day 1, such as being able to run Titanium Backup to easily port over your apps and data; and being able to run GravityBox (an XPosed module) to tweak the UI however you would like.

kent1146 is right that the unlocking the bootloader will totally wipe your phone, including the internal SD card. I had already set up my phone before unlocking and expected to lose my apps and settings, but was shocked to also lose everything on the internal SD.
When I transferred over from my GS3 the first time, I used the NFC/WiFi Moto Migrate app during initial setup. That was a mistake. It took forever and stuff didn't end up where I wanted it, plus is only works for some of your data. After unlocking my bootloader, I simply copied my GS3 internal SD contents to my computer over WiFi, then copied what I wanted over to the MXPE internal SD via WiFi. That was faster and I got exactly what I wanted and how I wanted it set up.
As for your apps, Google will take care of that by downloading (over WiFi) all the apps that you have on your current account to the new device, along with your contacts and a few settings. I recommend that approach to get a clean start with the new phone. Garbage accumulates over time, and it helps both performance and SD space to start fresh. I use TiBackup religiously, but chose to restore only a few app settings with it on the MXPE.
Without root, if you're decide not to, helium backup worked amazing for me
Well I will try helium at first, because I realy want to test the phone before unlooking it. And in that case I think I could do a Nandroid BAckup with ADB and restore it in the same hardware after unlocking the phone.
I will root if I get a lot of battery drain to see what appened.
When we have the root do we are able to get the OTA upadte or we need a patch for it ?

We won't know for sure until the first OTA update is released, but I would guess so if that's all we do. My warranty still shows as valid on Moto's website and the fastboot screen shows the OS as "original." With that "original" designation, I'm guessing that OTA updates will probably work. We'll see for sure come Marshmallow.

You won't get OTA if you root.
Rooting will require you install a non-stock bootloader (TWRP), which wont automatically install OTA. Plus, root access will modify /system files, causing the OTA to fail.
Typical process for updating an unlocked and rooted phone is to restore your recovery and root access to stock, take the OTA update, then re-apply custom recovery and root. Or, just wait until someone has a flashable ROM that contains the OTA

Hello there!
I rooted my Nexus 6P, as I've done with every Android I've owned since my Nexus One, as soon as it arrived.
However, I really like NFC payments (we don't have Google Pay in Spain, but there are several banks that offer that option) and when the January security update came out, I un-rooted flashing everything.
After that, two of the bank apps worked, but one of them still refuses to do so.
In addition, I've been suffering from very, very, disappointing battery life: no more than 2 hours SOT and having to recharge twice a day.
So, I've decided to start from scratch, using the latest image that came out today.
But I have several questions and I'd be very grateful if somebody could answer them:
- First, and most important. I've been using Titanium Backup since the dawn of times in order to preserve my settings. I've a couple hundreds apps installed and making each of them behave as I like is a nightmare. Is there any rootless backup solution? I know Google backs up everything, but I don't know if every setting will be restored as I want.
- Second... actually there are no more questions, I can look for how-tos on how to flash the image, go back to default recovery...
Thanks in advance.

In titanium backup you can have it export your backup to an update.zip that you can install via twrp. Having twrp as your recovery does not break Android Pay, as does root, xposed, etc..
edit: yes this applies to now, after google made changes to the server side that broke the root work-around

I've been restoring what I can from my Google account for three phones now and, while it's best it's been on a Nexus, you still won't get app settings and full data restored, so Titanium is needed for that. I've never tested the zip export the first reply suggested, but that's an interesting idea. As for getting back to a stock install, there's a very handy guide at http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928 and it covers all scenarios thoroughly. The command line is really the fastest and easiest, as the guide includes code you can just copy and paste. I don't think it's been updated regarding root, because systemless as a way to preserve AP was just stopped by Google.

I have once tested the update option but what I got is only apps and not data. I'm pretty sure I chose app+data while doing the update zip.. Beware of such things happening.

Thanks a lot for your answers.
I've been reading and it seems that, without root, TiBa's update.zip file won't restore app data.
There seems to be another app, Helium, that does a neat trick. You have to connect your phone to your PC, and Helium talks to the PC so that it uses adb to create or restore the backup. No root needed. I think I'm going to take my chances with that.
ultyrunner, that's the guide I was planning on using in order to go back to stock... thanks again, you saved me the search
