Is it possible to have a rooted device, use nandroid to make a backup, revert to stock/unroot, and then restore data from that backup? Can you even use the backup after you unroot?
never tried that - although I do not see why not
odin back to factory reset
you will need to odin clockwork recovery as stock recovery will not work
three finger startup to Clockwork
then go to restore - advanced - pick the file and restore data only
I just learned about advanced restore recently but have not done what you ask
If it does not work you can restore to where you were with no harm done
remember that titanium backup only works with root access.
If you're stock then you won't have the recovery needed to do a restore from the nand backup.
Yes, you would have to have clockwork recovery installed also though. Then just odin back to one of the stock images. Then later re root and reinstall clockwork and restore back up.
If you are talking about EI22 and want to keep CWM as a recovery to be able to restore said backup then you will need a custom kernel anyway so that the stock recovery doesn't keep overwriting CWM. What is the reason why you want to do this?

I screwed up my phone a while back with the crappy samsung cable that comes with it. Ever since it has been slower and my pc won't recognize it no matter what I do. So I bought a new cable and I wanted to revert to stock to try and start over with the rooting and custom rom process, but I didn't want to lose all my contacts, apps, music, etc. in the process.

OK. once you root again and have CWM back on you will be able to restore everything. So Odin away to EC05 stock, one-click root, flash a GB ROM and restore your data.
Well you should always be saving your contacts to your google account, then when you sign back in it will just use your account to reload your contacts. Your music is saved to SD, so when yiou open any new music program it should search your SD and find the music. Likeness previous posts, the issue your going to have doing this is not having a custom recovery...you wont be able to restore a nand with stock recovery. I agree with previous posts, it sucks you'll lose data, but the most functional and clean way to do this would be to Odin to EC05, use the EC05 to EI22 modem zip in the development section, and flash your custom rom and kernel. If you are concerned with performance and lag, see Universeral Adrenaline Shot and Supercharger script...good Luck!

Hello All,
About to be first time rooter and want to ensure I have a complete understanding of how things work before I fully commit. I’ve been trying to piece together information from various threads and I think I have a basic understanding of how things work. Can you please help me verify?
1. When you flash a ROM, the ROM automatically comes with a kernel. The kernel can be stock or custom, but regardless, all ROMS have a kernel automatically bundled when you flash the ROM. Correct?
2. Once you flash a new ROM and the corresponding kernel it comes with, you can swap out the kernel with something else, as long as it says it’s compatible with that ROM version. For instance, if the ROM says it’s built from 4.0.4, as long as the kernel you want to swap says that it’s compatible with anything 4.0.4, then you are good to go. Correct?
3. Radios need to be updated manually. Most ROMs and kernels do not update the Radio in most cases (or do not have radios bundled)…. With one of the exceptions being the Official Google ROMs. If I were to flash a leaked Stock 4.0.4 OTA Verizon ROM, I would actually get a new ROM, Kernel, and Radio. Correct? If I were to flash AKOP (or another popular ROM), I would get the ROM, bundled kernel, but NO radio. Correct?
4. A Nandroid backup backs up the ROM, Kernel, all applications installed, app user configurations/preferences…… basically everything EXCEPT the radio. If I were to restore a Nandroid backup, there is no need to restore apps and reconfigure apps/preferences…. It’s a snap shot in time (or whenever the last backup was made). Correct?
5. Using Titanium to batch backup apps/preferences is really only necessary when you want to flash a new completely different ROM and want to restore your apps from a previous completely different ROM. Correct?
6. Let's say I'm rooted and unlocked boot loader and on a custom ROM..... Verizon pushes out a new OTA update Stock ROM (let's say 4.0.4). What do I need to do? Restore 4.0.2 Stock from Google's developer website? If I were to restore the Google developer Website 4.0.2 version, my assumption is that I lose root (boot loader still remains unlocked). Do I need to re-lock the boot loader for Verizon OTA updates?
7. When I install a new ROM, do I loose root unless the ROM specifically says it comes with Root?
****** additional questions/verification added after sean and artvandelay responded ***************
8. Nandroid backups do not back up the SD card folder. This should be done manually (copy directory to Computer every once in a while). Correct?
9. When I installed space heavy games, I should have installed the game data portion (when it prompted to store at App level or SD Card Level) in the SD Card directory. Now if I Nandroid, It will be unnecessarily larger because it’s taking the game data stored at the app layer correct?
10. When you flash new ROMs or restore Nandroid backups, the sdcard directory remains unaffected. Correct?
11. Only when the boot loader is unlocked/re-locked is when the SD Card directory gets wiped. Correct?
12. Let’s say I need to restore to factory (back to stock – original ROM, Kernel and Radio, no traces of root, locked boot loader, etc.)…. All I do is go to Google’s DEV download ROM site, download the latest official ROM. It will restore the ROM/kernel combination and the original radio associated with the stock ROM, gets rid of all traces of root (since stock does not have root access). I will have to manually re-lock the boot loader (which will in turn wipe the SD Card directory). Correct?
13. Can someone shed some light on "GAPPS". I realize they are a bundle of Google Apps, but once I install, will I still get updates from Google Play when updates occur? Do GAPPS just save time from having to manually download? If I restore from titanium backup (after ROM and GAPP install), I need to ensure that I do not restore any app that falls into the GAPP category correct?
So did I pass? Is my understanding there? Am I missing any essential basics? Thank you all for your input!
1)correct
2)correct
3)correct
4)correct......it also backs up radio too
5)usually a good rule with tb is to only restore apps and app data, and not system setting an prefs so things dont bug out going from rom to rom
6)usually best to wait until dev updates their custom rom to new firmware(devs update rather quickly) better than unrooting then rooting stock rom only later to flash a custom rom that has been updated to latest firmware
7)most if not all custom roms are already pre-rooted
YOU PASSED!!!
Research is Key
Thanks sean.... especially for elaborating on bullet point #5. I think I've read that somewhere regarding only doing the user apps/apps data, but forgot to ask. I'm pretty excited about doing this.
A Nandroid will definitely not backup your radio.
Did a quick search around the interwebs.... artvandelay seems to be correct. The majority seem to say that radios will not be backed up.
Hello.
If I have a T-Mobile Samsung Galaxy Note 2 that is rooted and have CWM and have some apps installed on it, How can I update it's official firmware while keeping it rooted and keeping all of my apps the way it was before?
Sorry if question is easy or repetitive. I couldn't find the answer.
Thank you.
rooting or unrooting doesn't modify your apps, but if you're worried, while you're still rooted, I would backup all your apps using Titanium Backup. Then if something does happen you can restore it back. That is of course, once you unroot, update, and reroot again.
Download full rom here http://www.sammobile.com/firmware/?page=3&model=SGH-T889&pcode=0&os=1&type=1#firmware then use mobile odin to install it, injecting root at the same time.
I have no problem retaining ALL data after updated with Kies. Regaining root is no sweat as well.
But remember to use Triangle Away to reset flash counter.

I would like to try doing this will mobile odin. Could you provide a little more detail. Did you put file the internal sdcard? Also did you do a wipe of any partition? Does wiping data and cache option also wipe internal sdcard.
Thanks!
In mobile odin you have the option of wiping dalvik and cache, it wont wipe anything else. I had an external sd card that I always put it on. Very easy to do and it works perfectly. Just make sure you check mark to install ever root, super su and mobile odin.
used mobile odin pro

Used mobile odin pro. Worked like a charm! Recovered root, all downloaded apps and settings were intact via Titanium Backup. One thing, if you want to restore the state of a rom specific app (like the calendar), Titanium will warn you that you could have errors because you have a different rom. For this case I restored data and then calander showed all appointments so good to go here. Also, I had used the xposed installer to modify multiview such that I could run all apps in multiview. Worked fine with this rom. One curious thing, if I now check for device software updates I no longer get the message that my device is "modified" and am ineligible for updates. This is nice! had thought that you couldn't avoid this even if you used triangle away. Thanks again!
How do I re-root my Tmo Note 2 using heimdall? I was rooted, then updated to 4.3 via Kies. I lost root, and do not know if I am supposed to follow the same steps when I rooted my Note 2 while it was running 4.1.2. Any help will be greatly appreciated. Thanks!
So I have flashed some customer roms and then used odin to go back to stock after failing to restore a back-up using TWRP. After using Odin and the latest factory image from XDA. I am still showing signs of old flashes. I would like restore the phone completely back to factory. I am not sure if I need to reformat something using twrp. Can anyone help with some advice?

If you need to send it back, you need to:
wipe data/factory reset
reset flash counter (requires root, triangle away)
odin stock rom
The root toolkit in original development forums can babysit you through the whole process

Elaborate on what u mean by signs of old flashes
Odin should put back stock, u will keep storage and sd untouched
If you flashed a 4.2.2 aokp cm10 rom I think it screws up nandroid restore folder, it redirects restores to data folder...
I lost my backup too
Chain fire app has root away script use that to remove any sings of flashing

I infact had flashed AOKP. I was seeing signs of it left behind even after using odin to go back to stock. This is not my first Sammy device and havne't run into this issue before. I will try wiping things down multiple times. I think the thing that maybe bothers me the most was after going back to a factory image the last time Samsung Kies would not even check for updates saying " your devices current firmware is not supported to update from kies"
This is new as I have had my Note 2 rooted w/ custom recovery since it came out and had been able to update using kies in the past, just wasn't able to use the OTA updates from the device. (which I knew from the past)
Anyways I hope the clearing multiple times data/system/cache clears it up after another Odin flashing
I finally figured out how to root my phone (thank Sithis)
I just flashed TWRP and SuperSU. Sadly I was only able to recover a handful of photos from my whack phone factory resetting itself. (my only reasoning for rooting, to use data recovery. I only found DiskDigger. didn't do that great sadly)
I think I MIGHT have picked up some sort of malware or virus; not entirely positive but since rooting, my phones camera flash randomly goes off as if something is taking pictures. I have GO Security and 360 Security downloaded and it didn't find anything. I don't know how thorough those apps are but hopefully they would have picked up any malicious thing invading my phone.
I know there is an unrooting option through the SuperSU app. Again, I don't know how "complete" of an unrooting that'd be.
I honestly wish I had the links I used to download TWRP and SuperSU. Maybe to see if anyone could figure out if they were legit.
I want to unroot, then factory reset. Would I have to flash a stock ROM before hitting the 'unroot' button? How would all this work? Anyone figure out how to get OTA updates after a complete unroot?
If anyone could point me in the correct direction I'd be thankful. I just don't want to deal with the security risks of a rooted phone and would like it back to stock. If I could do that without flashing a ROM to my phone that'd be great.
Since I couldn't find anything of the sorts for my N910PVPS4DPE2.

You could press that un-root button now but most likely you cannot take the next OTA without flashing the stock tar in Odin. Modifying some partitions will break OTA updates. Having custom recovery won't work.
I don't think it's ever been established as fact but in theory, you could root a stock phone with Chainfire's CF AutoRoot for Note 4 in Odin. Leaving as that root installer rooted, you could un-root later for OTA update within SuperSU application. It would prompt you to restore both kernel and recovery with the original stock ones and then reboot. *But* if Samsung flags modified read only partitions as being modified, even if modified temporarily, OTA would still be denied for modified status trip. Dunno if anyone has confirmed the theory on our phone or not.
To answer your question, I think you'll have to flash the stock tar in Odin to restore your OTA capability. I would recommend you press the full un-root. You can restore the original kernel, if it was stock, at prompt. But most likely you cannot restore the original recovery if flashed manually. You'll need to flash the stock tar again to both restore read only partitions and stock recovery. If you forget to to perform full un-root, I think factory reset will be enough to clear root and remnants with a stock tar flash. (Stock tar flash should wipe internal memory but to be sure, you could wipe that too).
It's up to you, you could wait until the next OTA to flash the stock tar.
For your camera issue, it might just be enough to factory reset for now.
Have you considered Titanium Backup to backup and restore applications? A lot of rooted users use that. I'm not sure copying and restoring a disk would mesh with Android package id used to link data to original application with proper linking and ownership. I do know that Titanium Backup complies with that. If the package id gets skewed, restoring data may not work as expected. Something to check or confirm beforehand. Just a suggestion.

Thanks for the reply man!
Looking over it, it seems like a true hassle to go through finding the stock ROM for my phone and unrooting and that whole process. I think I'll stick with the root for now. I have a couple more questions if you don't mind:
1) If I kept root, could I perform a factory reset without it screwing up the root? I think there's a 'factory reset' option when I boot into TWRP. I would just like to know if it'd remove TWRP/SuperSU. I have heard a lot about Titanium Backup so I will be giving that a try before doing so!
2) Any chance you'd know if when the new OTA comes out, they will have it flashable for my N910PVPS4DPE2? I'm relatively new to all of this and I know if I flashed something not meant for my exact device; I might as well slap some cement on my new Brick Note 4. I've never seen any ROMs/Mods that say 'For N910PVPS4DPE2' specifically. Maybe I'm being overly cautious and don't have all the new lingo down. So, are there ROMs and mods for my phone that I'm just completely overlooking?
Thanks again for helpin a newbie out!
Stock tars are here:

A stock ROM with system based root that isn't easily wiped or lost is here:
http://forum.xda-developers.com/showpost.php?p=63028063&postcount=1
I believe factory reset still un-roots systemless root. There was a script that you may have been prompted to install to keep root but I'm not familiar with its retention capability because I use and prefer system based root in the ROM above. You can factory reset the ROM above without losing root.
You would need root for titanium backup. I would recommend factory reset and install the beta 3 ROM. You may not like the missing voicemail app. I use the long press of 1 key in dialer for voicemail. You could just save the apk and install with apk installer by tapping its file with root browser or MyFiles and install. But extract or copy and paste with root browser from current ROM.
OTA's can be expected nearly monthly now. Tars release a bit behind the OTA.
