Tab Won't Factory Reset

i've got a galaxy tab, no custom roms, not even rooted and i can't reset it. when i go to Privacy-->factory reset, it will boot into the boot menu, and i do the data and cache wipe from there, then it will only reset the homescreen. my accounts and data stays on the device. i've seen the problem once online, but can't seem to find anymore topics on it. does anyone know how to fix this problem?

I'm having the same exact problem. I can't seem to find a way around it, and I suppose I will have to send it in if I don't want to go into ODIN and deal with it that way.

Same issue
I'm having the same issue.
It does not matter how I do it the result is the same.
The 3G information is wiped out, all the applications are messed up, but my Gmail account, Facebook and accounts are still there. If I manually remove all the accounts using account manager, when I reboot the tab, they're all back!
I've tried:
Menu > Settings > Privacy > facotry reset
and I've tried holding down the Volume Up button while booting and selecting facotry reset and clear cache. No good...
At this point I'm being sent a new Tablet, but I really want my personal information cleared before I send it back. How can I "jack" it up? I've looked for a Verizon ROM to see if I can put that back on using the SD card, hoping that would wipe it, but can't seem to find one. Or any CDMA Rom that might wipe everything out.
After I had this issue I even installed z4Root and rooted teh phone, hopeing to use an App that remote wipes, but the results were the same and NOW the SuperUser force closes everytime I try to open it. In fact, almost all the apps seem to force close when starting them EXCEPT market and Gmail.
Help!
--- update----
Changed my passwords on Gmail, Facebook and Twitter. After about 30 minutes the tablet finally stopped displaying my information and started prompting for passwords.

This is an old thread but I'm having the same problem with my Sprint Galaxy Tab. Factory resetting through recovery mode, settings, flashing a new rom, etc don't work and pretty much every app crashes as soon as the tab boots.
Anything I can do before sending it in?

Anyone else facing this problem? I did have two google account in my tab. I would like to remove one of it which I dont use anymore. BUT the system request me to factory reset if I want to remove the account.
BUT the problem is, i'm afraid if I reset, others problem will come later.
I always heard people taking "Don't fixed it if its aint broken". LOL
So, over my curiosity to see either this "unable to remove account" is a common problem which involve my tab also or not?
Curiosity kill the cat!!
haha..so afraid now...

same issue
I have the same problem.Problem come on gingeIrbread.On froyo factory reset works normal.I flash back to froyo but can't do enything becouze it's crash when go to settings wizard. I go to recovery mod but can't whipe factory data and chase.Flash back to gingerbread 2.3.3 but nothing change.Help please.I have euro tab.Sorry for my bad english.

xena0709, I know if you flash the overcome safe gb rom then it wipes everything. You should try that....
Overcome is GSM only...

I try that.Didn't work.Thank you for advice.

In recovery it says Can't access to '/system/csc/TWO/system/'. I don,t know what to do.

Solved.I took my tab to Samsung center. Replace the mainboard.Now it work.

had this on my Sprint Galaxy Tab after the Gingerbread update. Sent it in and they mailed me a brand new unit a week later.

hello all,
i know that this thread is very old. but i faced this problem now, i want to know if flashing the stock ROM will solve this problem or the only option is to change the motherboard. As my tab is out of warranty and this will cost me a lot to get motherboard changed
thanks in advance.

In case of trouble go back to stock ROM first.

Galaxy Tab P100-cant delete prior owner info

Ive searched and havent been able to find a solution to this, although Ive seen it asked before.
Galaxy Tab P100 bought from a pawn shop. It still has the prior owners (unknown) gmail info minus p/w. I cannot remove the account, or access market because of this. Everytime I tried to data reset (both via Privacy settings and also CWM), add a new rom, or add apps - after I reboot it goes back to the prior owner settings and apks.
I have Odin'd/Heimdall with different roms but they dont stick. Different kernels install though. Ive added two different CWMs. Superuser breaks after every reset - I gain, then lose, root. Ive rooted/added root explorer and deleted accounts.db and user.db - they go back after. Ive spoken with Sprint and we tried everything they had, as well as a ##786# and MSL number (resetting phone activation I think?). Their response was take it in to send back. I want to fix it myself.
It seems to me that this prior info is overriding and reinstalling every reboot, preventing any new flashing/etc from taking place.
Here is my question. I took it apart this morning and disconnected the battery (thinking maybe it will wipe any memory). But does it have a CMOS-type battery? I noticed there is a small round battery-looking connection soldered into the mainboard (see here - step 7/8 http://www.ifixit.com/Teardown/Samsung-Galaxy-Tab-Teardown/4103/1)
Does anyone know what this is? I dont really have anything to lose, but Im not great with a soldering iron, but will try. Im thinking this might be for the memory, and disconnecting/reconnecting this would erase any permanent user information, freeing it up for me to add mine.
Or if anyone has any new ideas I would appreciate it.
Thanks for the time. Ed

It is not a battery backed memory, it is a NAND chip.
Sounds like the chip gone bad.
Sent from my GT-P1000 using XDA

Just an update.
I did not do anything with the round battery thing, as priyana stated the memory is stored on a nand chip. I put the tab back together.
I rooted again, and found the ea24 firmware and loaded it via odin. It took, but the prior user info was still there, and everything (I mean a crapload of apps) began force closing. I did confirm that ea24 was on it. I then flashed back to ef17.
I contacted Sprint repair store again, and they told me that they probably cant fix it, and its something they have to send back. They said that I have done all that they would do in-store.
I dont understand what could be wrong, as I found the prior owner and spoke with her. She had no issues with it. It worked fine prior to her getting rid of it. And it works fine, I just cant get rid of any prior info. I googled it and it seems like there are people out there who have the same problem, but no one has an answer, including sprint or samsung.
So much for my venting. Ill keep trying to find an answer.

First of all, I'd like to apologize for posting something that won't really help, but I recognize this from somewhere else. On some devices, there's some kind of file (that you can delete via the adb prompt when you're root) that on every bootup checks to see if the installed ROM matches stock, and if not, restores to stock. This sounds exactly what you're experiencing when you mention that no ROMs "stick".
I think you should try to look into if there's some files that need to be erased in order for a ROM to be cleanly installed that you haven't gotten rid of. It might also be some kind of feature that the previous user enabled, so maybe it's somewhere around in the settings that you can disable it, who knows.
It definitely does not sound like a memory issue because I don't see how a memory issue could make the stock ROM suddenly appear again after you've installed a custom ROM through CWM (assuming CWM gives no errors or anything and the custom ROM has actually been wiped).
Maybe you can do a more thorough wipe of the device memory manually with some guidance from someone who knows more about how these tablets work :fingers-crossed:

I agree with you about some type of file and bootup. Thats why I went with maybe it being a cmos/nand issue. I couldnt understand that I wiped everything, and information was still coming back. It makes me think that somewhere, something is being stored separate from the main drive.
Ive used the factory restore, CWM (2 different versions - 3 and 5 I believe), and wiped data (factory reset), cache and Davlik three times each before I flashed the CM ROMs. And I have not had any errors or problems installing any of the CWMs.
I spoke with the previous user, and she did nothing above turning it on/off, and using it. I am not on the Sprint network with it, and the wi-fi doesnt turn on until I set it up, so I cant see it being something that contacts Sprint and OTAs from them.
Can anyone tell me if, using ADB, there is a more thorough wipe I can perform ? More than the normal one done through CWM or Android factory restore?
Something similar to the reformatting of a hard drive?
Thanks
Ed

I have the same problem. Did you find any solution?
I believe the previous owner info is stored on sprint servers. When you reboot, it downloads all the crap.
The long time required to reboot explains the slow transfer of data - wireless.
These wireless service providers are pretty sneaky.
Thanks

Hi,
Have you tried formatting both internal and external Sd via Windows? (connecting via USB)
You can also try CM10, it has a different memory map which will write your device completely.

[Q] Really annoying issue with Google account sign in.

So I've been having this strange problem and I am convinced there is no simple solution. Every time I wipe date and install a rom, I try to sign in to the Google account during setup, and I keep getting an error saying that there was a problem communicating with Google servers. I've done a factory reset, formatted everything, tried different RUUs, and nothing seems to work. I just can't sign in on a Sense 5.5 rom. So now I want to clear the phone completely, because there must be something that no form of wiping is touching. A stock RUU can't solve the problem and I don't know what can. I even tried using LTE instead of WiFi and still no luck. Does anyone have any clue about this?

But I have wiped everything including internal storage and used usb-otg to install roms. Nothing works. Are you sure that will fix this?
EDIT: Can confirm that your recommendation doesn't work for me. I decided to flash a different rom (InsertCoin) and in this one I can sign in, but it won't sync, it just keeps saying "Google Sync error."

It did the trick for me. Also, I mount system in recovery before doing anything. I'm pretty new to this phone and never used any recovery except 4ext on my Desire and Evo so I can't be 100% sure, leaving data did the trick for me

I've tried a few new things so far. I used the mkfs.ext4 file to format the data partition as I think that's where the source of the issue lies. But I also used fastboot to format system. If this doesn't work then I don't know what else to to. I might be forced to run a GPe rom or some other android rom. I just strongly prefer sense.

whats happens if you start a new account

It won't work. I tried typing in random letters in to the user name and password box but it doesn't even try to connect.

Well I've got bad news. I managed to hard brick my device, so this issues I was having is not an issue for me anymore. But if anyone can help find a solution that would be appreciated as I'm sure someone else might be facing the same problem.

That's when you can't enter the bootloader anymore. You hold the power button and the lights on the bottom don't flash and it'll just vibrate a bit. But it's all good I got the phone replaced today. So then I installed the rom I was trying to install earlier (the one where I couldn't sign in to google) and I ended up having the same issue. So I think I'm gonna just use ARHD or something.

I'm pretty sure it's not a virus (are there even mobile viruses?) so you should be 50% calmed down now. As for the problem, I've got no idea what's happening, but you should flash a completely stock ROM (without wiping nothing at first) and see if the problem persists. If it does, try factory reseting the newly installed stock ROM and then everything should be OK (however make a backup of all your important data as you'll lose it).

[Q]Help me with this particular N910T

Hey folks, first thread ever, I really need help with this troubled N910T, DOK2, Android 5.1.1
Whats wrong with this phone:
The contact app will stop everytime I open it, since contact app is combined into Phone app, so the Phone app will also stop everytime I click on it. However, the situation will be fixed if I change the locale to English. (The phone belongs to a Asian friend)
One of the instant message app, the Wechat, similar to Whatsapp Messager and Facebook Messager, will not receive any kind of notification, at all.
The phone's battery drop from 50% to 1% then turn off itself in minutes.
The last two problems may be unrelated issues to the first one, and that is not the main reason I'm really here. I have ODIN flashed the latest firmware over 10 times and all THREE of the problems still exist after all that.
And whats bothering me is that ODIN flash firmware WILL NOT FACTORY RESET this phone, that doesn't make any sense to me. Please let me know if I make a mistake about that, because every other phone or tablet I have worked on before will always be factory reset after flashing a OEM firmware.
I have also flahed TWRP and wiped everything from the System to the internal storage and reflash the firmware but the problem is still there.
sort of things have been done to the phone may have something to do with the problems:
installed the zips I got from this thread http://forum.xda-developers.com/not...pt-touchwiz-bloating-script-222-apps-t3258537
it debloated the phone.
the phone was lost in a rainy day, found again two days later. Remote lock and wipe preformed via Android Device Manager but the wipe process never go through.
Please let me know if the phone is worth saving at all, I have spent days in this phone fixing and researching for solution. I found no similar issue around here, and the phone is out of warranty.
Thank you and please let me know should I throw this thing away.

Battery needs to be replaced. Are you sure you flashed right firmware for 910t not 910t3?

It's a N910T, and the ODIN sucessfully passed everytime but will not factory reset the phone,.

Have you tried going into recovery and factory reset it yourself

Many times already.

If you haven't done so, you may want to do a clean install which means wiping system, data, dalvik and cache at least three times in custom recovery such as TWRP. Then you can try ODIN baseband, bootloader, rom and kernel (if rom doesn't contain one), custom recovery. Next you boot into customer recovery again and do a factory reset and that should do it. Let me know if that helps.
