Hi,
I've read all the unroot threads and I still haven't found the answer, so could someone please explain. I've decided to unroot but would really hate to have to wipe everything and set it up again.
I have a rooted 3.1 WW TF with cwm.
1. Is there a way to unroot without losing all app data etc, and then be able to use OTA to update to 3.2? I guess the first step would be to flash stock recovery but then what?
2. In the 'Batch script Pure Root Method' thread in the developers forum it was suggested that flashing stock boot and stock recovery and uninstalling the superuser app would achieve this, but from what I understand people have tried without success?
Many thanks.
Anyone?
The unroot options available on this forum don't require you to wipe the data.
Just the cache, so you won't lose your apps and/or settings.
Good luck.
Thanks locutus7o9,
However I'm still not exactly sure which of the methods allows this, I would really appreciate a link.
1. Download the firmware you wanted to downgrade to.
2. Follow the instruction here: http://forum.xda-developers.com/showthread.php?t=1093403
3. No data wipe

Hello!
I was just curious and asking myself: would it be possible to flash a rom like ics and not doing a factory reset (like the ota updates)?

Anytime you are flashing a new rom, you need to wipe the previous data otherwise you'll have conflicts galore. It's a pain, but if you back up well, you can restore pretty fast.
I know where the op is going with this. All the methods of rooting I have found so far have you unlocking and flashing CWM. Doing this will wipe everything. If you could root first, things would be a little easier.
Is it possible to root it? I have unlocked the bootloader already. It's my understanding that falshing a custom recovery wipes my phone but I see no stock roms available. How can I root it with out wiping and if it must wipe, how do I back up my rom?

i dont think you'll wipe your phone with a custom recovery..i have rooted mine without wiping data..you can back up your phone using the custom recover first..
Follow the steps in the dev section in the unroot thread
you can use MyBackUp Pro before you root. But you can't keep all thru this process. Although not wiped, I would still bu sdcard before rooting.
flashing a recovery will not wipe phone--i recommend twrp
if easier to follow thread to unroot and flash cwr. do that. you can always flash twrp later
do a lot reading on all this first, so you have an idea of what/why of flashing steps
So I decided to go back to stock hoping to get OTAs. I was on stock rooted and used ODIN to flash stock unrooted as per the directions in the sticky thread in Android Development. I restarted the phone and superuser is still there. Did I fail to unroot? Also, will this affect my ability to get OTA if it is unrooted?

You could uninstall the .apk itself / or delete with root explorer

You did something wrong, or somehow restored it, or maybe you flashed Root66 or an already rooted image by accident, because if you restored to completely stock, unrooted image through Odin, it basically overwrites the entire /system partition (operating system), there should be no apps or anything left that was custom installed. Before you did this though, you should have gone into recovery and wiped cache and data (make sure you backup all your data because wiping data will delete all your data on the phone and all your market apps too, except for your external/internal sdcard data). Anyway, flashing through Odin completely wipes your /system partition, so it would be impossible to have anything lingering from before. What this means is that you either installed the wrong image through Odin and it's still rooted, or you didn't wipe data before flashing and Superuser must have been installed as a user app then. Do a factory wipe (after backing up data you want to keep), then reflash stock rom again.
Why the hell would you ever accept a ota? A dev will base a ROM on whatever ota you feel you need if there is not one already, without shady Verizon crap. Your asking for trouble

I need a help from anyone,please...
I've succesfully updated to JB (vie OTA).But i want to setup clean JB,then i want to do a factory reset
or wipe dalvik-cashe-data on my Tablet.
If i do so-do i loose root? (it was saved with OTAKeeper befor update to JB and restored after that
without problems).Or do i lose OTA keeper (or backups from Keeper) to restore root after wipe all??
Please suggest me, i'm very curious about that and want to make all right
from the Beginning...
Thanks in advance,
Val

You can do factory reset and still have root. Make sure you do a full backup first with Tibu.

These are the steps I took.
1. Make sure you Install and use SuperSU
2. Install Voodoo OTA root keeper. Make a backup
3. Factory reset
4. Install super SU from market
5. Install vodoo from the market.
6. restore root in voodoo
7. open supersu
Might be an easier way to do it, but that gave me no problems."
Thank you very much for your answer!
I will do exactly so as you said!!
Way back when, I modified my 4.1.2 tab so I could use the Switchme app. Since it hasn't had a software update since then, I need to unmodify my system, so I did a hard reset but that doesn't seem to unmodify it so I can get it updated. Do I have to flash to a stock ROM, or won't that help either? I've done a hard reset twice now and restoring my Samsung account does seem to work either. Help PLEASE!
Nope it does not.

5 . Reboot the device and Leave it be..
Never flash anything on any Device until you know how to get back.
There are many Threads with step by step details on the above. even many youtube videos..
Good Luck
Hey,
I don't think you have to flash back to a stock ROM in order to upgrade to a different ROM. I was able to upgrade my tab with 4.1.2 (I can't remember what ROM it was) right to GNABO then a few hours later to Carbon, and a few hours later to Hyperdive and I'ts running fine with no issues besides the Aroma freezing, but what else is new...
You shouldn't have to flash back to a stock ROM to flash to a modified ROM, reason being is the modified ROM Flashes over the current ROM on the device, so the original ROM will be deleted anyways. The new ROM contains the updates for you, that's the advantage of androids. I recommend trying a few OS's before you pick the one for you stick with it. If you want to go stock there is a thread somewhere in the DEV section with the stock ROM just do some searching.
Make sure when you install a ROM to ;
Backup your device and make sure to keep a copy of the backup to your pc!
Boot into CWM Recovery or TWRP
Wipe data / factory reset
Wipe cache
Wipe dalvik cache
Install ROM from SD
Good Luck
