[Q] Diagnosis pse: settings and files lost on reboot - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

I have bought a second-hand Galaxy Tab which will not keep changes in settings or any uploaded files or IDs after switch off and restart.
This means I cannot root it, as any uploaded files with Odin are lost on restart.
Can anyone help me please? I have tried all the usual resets to no avail.

No-one interested in a tricky problem challenge???

Hmm, I thought this might intrigue the experts, but to no avail.
Where the hell do I go for an answer to this problem: rooting cannot be done as flashed files will be lost on reboot.

Hi. Thanks for getting back.
I have gone up and down the forums for ideas. (for over 3 days now).
The story so far:
I have tried to flash the overcome .tar file for my model using odin 1.83, but get a red box and a Fail! : error 0X140005. I followed the Overcome guide VERY carefully, got the yellow COM box, put the right file in the right box, but when I hit the start button, it fails.
I can boot into "Download". I have tried restore after wiping the cache.
With normal power up, the OS seems to work partially, in that I can do all the things I want to do, but all the settings, WiFi passwords, uploaded files etc disappear on reboot, and any uninstalled programmes re-appear. It seems that it won't permanently write to, or erase from, "long term" memory.
Before this,I have done a full cache wipe and factory restore but no difference.
Thoughts:
a) I am wondering if a previous occupant has tinkered with it and messed up the memory partitions? is it all RAM?
b) As it is stuck, it is stuck with USB debugging disabled. this will be maintained on reboot: could this interfere with Odin?
Any suggestions would be very, very gratefully accepted.
FG

Dude i ask this in another forum you posted, did you use odin to install recovery or not? if you did then just boot into recovery and wipe all - then flash galaxytab or any flashable roms that way.

As I said in the second paragraph: I tried to use odin to install recovery, but got the big red square. The file did not transfer.

No your second paragraph said you flashed overcome. Not recovery
So if odin is not installing recovery can you boot into fastboot? Power off then press power n volume down then go to fastboot mode and install recovery that way. Check this thread for info. . http://www.galaxytabforums.net/forum/galaxy-tab-10-1-general-discussions/1044-my-galaxy-tab-10-1-wont-power-up.html
Then flash a cwm flashable ROM

OK, thanks for the steer and your patience. I'll get to work.
I'll report back (eventually!).
(Please remember that there is an awful lot of jargon and TLA's to learn for us newcomers, even if willing).

hi again; well no success so far.
- I downloaded and installed SDK (software development kit: for other noobs like me)
- I downloaded and installed recovery.img, and installed the google USB drivers from the extras
- I checked that the fastboot.exe, adb.exe (android debug bridge) and recovery.img were all in the platform tools folder.
- got into "download":- odin mode
- plugged in the tab and tried to launch "adb start-server" from cmd screen
(I was in the right directory at the command line), but no cigar: nada.
- I went back and did the PDAnet routine, but still no joy, no devices shown
there were no error messages either, which made me think the usb was not communicating with the tab.
To try this out I used Kies to transfer a photo file to the tab, and viewed on the tab it after disconnecting, so tranfers do take place.
Sure enough, after rebooting, the file was gone, like all the other settings and changes made in the past.
I also tried adb when the tablet was on and I had checked usb debugging. In this case, adb recognised the device and returned the serial number.
It does not do this when in cwm mode as it will not remember to keep debugging on when I power down.
Any other ideas anyone? can I switch debugging on from the command line before I try to recover?
FG, (now getting a sore head and worrying if I have p***d my money up the wall.)

Funny, when things get really tough, the helpers disappear.
Still no solution.

Oh dear: silence again.

AFAIK you won't get a response in ADB when the tablet is in download mode but you should when the tablet is in CWM recovery mode.
If it were me I'd odin a stock factory recovery to the device and a stock factory rom for it. Then i'd boot into stock recovery and do the factory reset to see if that cleans things up. You should probably link to the source of the files you're downloading as well as provide specific model of your device so people can verify that you're flashing the right files.

I'm totally confused by your steps here
you went to odin mode and used adb? or did you go into fastboot and adb the recovery?
step by step here
a quick overview of it is to get your tab into ODIN mode and use ODIN to reload a copy of the stock image to your tab. This erases all of your previous data but you can reinstall those later. But at least it gets you back to a working tab - Note this is for the 7510 - the wifi tab
1) Download this file - MEGAUPLOAD - The leading online storage and file delivery service
2) extract the file
you should have the following
a file called GT-P7510_USB_Driver_v1_3_2360_0-Escape - this file is the USB driver for your PC, if you don't have the driver installed already, run this
a folder named Odin3 v1.85 - this contains the ODIN executable file
a folder named KME Odin - which contains 2 files - android_fastboot_emmc_full_p4_16G_32G.pit" and a "P7510XABKME_P7510UEKME_HOME.tar"
3) Power down the tab
4) press POWER and Volume Down at the same time until it powers up and you should see 2 logos - USB and triangle (note the retail wifi version might show 2 different logos, android on right and bag on left - left is recovery and right is Odin/download)
5) press volume down to move the selection to the triangle (or the icon on the right)
6) press volume up to lock in selection. You are now in ODIN/download mode
assuming all your drivers are installed to your PC, plug in the tab via the USB to your PC
run the ODIN executable
only Auto-reboot and F.reset Time should be ticked
after a minute, the ID:Com box should turn yellow -if not you may have driver issues (try this driver http://drivers.softpedia.com/progDo...SB-Driver-for-Windows-x86-Download-96692.html)
7) tick PDA and click the PDA button and navigate to the KME Odin folder and select "P7510XABKME_P7510UEKME_HOME.tar"
8) select the PIT button and navigate to the KME Odin folder and select the "android_fastboot_emmc_full_p4_16G_32G.pit"
9) Select START
it should start writing the image to your tab and once done, should reboot you back into stock
in case you want to go ahead and flash 3.2 -
use this pit file - http://forum.xda-developers.com/attachment.php?attachmentid=784889&d=1321486916
and use this for the PDA http://hotfile.com/dl/135008863/06c...EKMM_P7510XABKMM_P7510UEKMM.rar.html?expire=1
if it asks you for Password for the 3,2 file use : sampro.pl
when resorting to odin and first booting up, you might get asked for a password, the way around this is to
a) power off,
b) press power n volume down until you get 2 icons left is recovery right is download.
c) press volume down to select recovery icon then volume up to lock it, you should then see the recovery menu
d) then use volume buttons until wipe data/factory reset is highlighted press power to do it
e)after its done wiping, select reboot n you should be ready
Now the key thing here is installing the right drivers - after installing teh driver, connect the tab and see if the drivers are installed - go to your pc control panel and check if you get a triangle with an exclamation point. If there is, right click on it and select update driver, then manually choose device - navigate through and find the Android or samsung device (cant remember the name off the top of my head)
if you get stuck, report on which part you got stuck on - currently it seems like you're mixing and matching different steps so it is a little confusing

Hi again, sorry to confuse you but I was following your suggestions in post #7 of this thread. when I got to step 5 of that post, I got no response from the device: installed PDAnet to get over the driver issue. and no joy.
When trying to install .tar or PIT files I get a big red box, even though the yellow COM box looks good.
When trying the data erase/ factory reset option in the "Download" mode, I get the error message "Can't access to /system/csc/XEU/system.
Steps 7/8/9 in your post above do not work: I have tried them a few times.
Sorry, I have run out of options, and thank you for your help.
