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.

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.

I have this same problem with a tab. Its not connected to sprint,has not been on the internet at all. Was there ever a fix for this?? Please let me know its a christmas present and i need to fix this issue. Thank you
For a couple of days now I've had 'Emergency Call Only' status on my phone, i.e. can't make calls. Internet is working fine (with or without WIFI).
It is nothing to do with the SIM card, the SIM card works fine in another phone and I've tried a different SIM card in my S5830i which doesn't work either.
I have the normal stock Android ROM installed and have never flashed any other ROM. The only thing I have done is rooted my phone and everything was still working fine for a while after this.
The origin of the problem seemed to coincide with my internal becoming full and as a result user and system apps crashing all over the place on the phone.
What's worse, if I dial *#06#, I get "IMEI ", i.e. nothing just blank!
Please advise, I've only had this phone a few weeks, I'm worried this is irreversible!
Did you put your phone on CDMA only (in mobile data settings), by any mistake?
If not, you can always try flashing the stock ROM again (using Odin), resetting all settings.

The short answer is no, the long one is that I have no such options under the normal menus in GB 2.3.6, but I can get to these settings by accessing testing mode. My current setting is "WCDMA preferred" and I have never changed this before.
Well as my phone is under warranty I was thinking of unrooting it, doing a factory reset and if its still not working, taking it back to the shop and pleading ignorance before I try flashing it!
Unrooting your phone and taking it back to the shop sounds like the best way. If they say the warranty's void because you rooted it or flashed a firmware (ODIN counter) there's something you could try instead:

Ok thanks for that, yeah I took the phone back to the shop today, they've sent it off to their engineers, I'll post again when I get it back, they said a couple of weeks. I've never flashed it with anything so the ODIN counter should be at 0 and I unrooted it and done a factory reset on it before taking it back so hopefully they won't realize or can't realize it previously was rooted.
As far as I'm concerned the phone isn't even fit for purpose unrooted as the 200MB internal storage space is almost insufficient for updates to system apps, let alone any user apps, which is why I rooted it in the first place, to get full apps2sd functionality!

Got the phone back today, well a phone anyway. Apparently they couldn't repair the old one, so they replaced it with a new one.
What precautionary steps can I take to make sure this doesn't happen again. Is backing up my /efs folder enough with regards to securing IMEI information?
Also, I was thinking I should install some decent anti-virus software, anything else I should be doing to secure / protect a rooted Android?
Alright, you guys might be sick of me, but I have a great deal of respect and appreciation of you skills and knowledge thus far. I flashed my cappy to CM10.1 this morning. After flashing, it seemed to load perfect. But two issue:
First, I flashed without my SIM card installed, as most of what I read said to do it in this manner. However once CM booted for the first time, it never said anything about "no network support"or "insert a SIM card for service" which I've seen on phones in the past when there's no cell connection. I shut down the system, inserted my SIM, then powered it up. The phone did not recognize a SIM card, nor give me any kind of error message. I put the card in upside down once, and it told me that it couldn't read it. It's as though the SIM drivers are missing. I know the SIM card is in good standing, because I had to grab my old Palm Centro to take to work. I popped the SIM in the back and sent texts and made calls all day long, no issue. Any ideas on why the i897 isn't reading it?
The next one is a reboot issue. The phone is rebooting in "sleep mode." Once the screen goes dark, it'll reboot after it sits. If I put it to 30 minutes before sleep, it'll stay on the whole time without rebooting. it's only in sleep. I saw there was an issue with some lower serial #ed phones, and mine does have this lower #. But it never did this in Gingerbread. NEVER! CM10.1 issue?
Thanks in advance! I hope these issues can be worked out, because I really like this phone and CM is awesome!

Since I'm getting zero answers, I guess I'll have to reflash. Should I reflash CM10.1, or flash it to stock first, then CM10.1 again?

Go check your IMEI, if it says 0 or unknown, you'll have to flash back to stock, backup your EFS folder (with a root explorer) and then work your way back up to CM10.1. If you get the issue again, you'll be able to replace your EFS folder with your backed up one and it will that problem.
Other thing, make sure your APNs are matching your carrier's.
Now as for the reboots, so many things can cause it. I'd make sure not to have ''deep sleep'' turned on, many phones reboot cause of it. Next thing, I'd try different governor and scheduler (towards performance). Next would be to try another kernel for JB (I believe there are 2 to choose from that aren't the CM one). and finally, if all else fails, you can try upping your voltage by like 50 each steps.
P.S.: A simpler solution would be to go back to stock and try another JB ROM.
P.S.S.: It can take some time to get a reply back to your questions as this phone is getting pretty old and we aren't many techs to still support it. That being said, it still gets a lot of love in the Dev side.
I'll add one more thing to Bwolf's suggestions. If you try reflashing or go back to stock then back to CM or whatever else and it's still not working you might look at whether there is a modem installed. CM should come with a modem but for whatever reason it might not have flashed so flashing a modem could fix the problem. There is a sticky in the development section where you can get any modem available for the cappy. Good luck and hopefully you'll get this figured out.

Good point, let me add to this as well
You'll have to flash a I9000 modem (from the modem thread), they're compatible with the I897 on JB.

CM10.x has its build properties set to allow you to operate without a SIM card. So, there may not be any error message if there is no sim card.
Have you tried turning off wifi, powering down the phone, removing the battery for a few minutes, clean the sim card with some contact cleaner, let it dry, then reinsert SIM before inserting the battery. Then power up and wait about 10 minutes. Just let the phone sit there. If you can make a phone call or access Internet via cellular data, then the SIM is good.
To BWolf's comment re IMEI, occasionally it happen that there is a number shown in about phone, IMEI, but it is the wrong IMEI number. While you have the battery out, check the phone label under the battery. write the IMEI number on piece of scratch paper. When you reboot, check the about phone, IMEI, to see that it is correct.

Not sure what the difference is. I only see a sleep option that ranges for 15 seconds to 30 minutes. If I leave the screen on all the time, the battery isn't going to last very long.

The zip file is used just to include the Read Me and to make for a smaller download file size. Once downloaded to your computer, just extract the One Click and Read Me out of the zip and follow the info and instructions contained in the read me file.

I'm new to this.
A totally random event. I restarted my phone one evening last week and it show no sim. Using the LG support tool I had multiple failed attempts to update the software. Then as sudden a the sim registration had disappeared it came back to life. All fine until again the phone just stopped registering the sim.
Phone is secondhand. And I have tried numerous times removing, cleaning and replacing the SIM. Tried another active SIM on the same network with no luck.
I've never had a 'bricked' phone so don't know what to expect but I imagine the phone wouldn't even boot up!
I have now rooted the phone and installed CWM recovery, still no joy and have in desperation performed a hard reset. Nada!
Software is V10h. I read something about EFS folder to backup but all I could find is a text file. The IMEI is not registering on the phone. It could be a very simple answer but currently I'm stumped. I have requested a replacement SIM but have little hope this will resolve the issue.
I hope someone has an answer...

re-flash 10h or 20a kdz. look for various tutorials on the forum. (btw, your phone isnt registring on network cuz your imei isnt being read, probably due to failed upgrade process
(or some other bug). it should be fixable though)
also, replacement sim wont help. its your cell phone that's faulty, either hardware or software, not the SIM itself
also, i'm not sure how it goes if your IMEI is blacklisted by your cell phone company - is it possible the phone was stolen? perhaps the original owner reported it stolen to his carrier and they blocked the IMEI?

If the IMEI is blacklisted, the phone will still show it correctly in the settings and the carrier will just block based on this. This is why changing an IMEI is illegal in most countries and why discussions on how to change it aren't allowed on XDA as it can get the site in serious trouble.

check if ur gapps are fine. reinstall all gapps. maybe u deleted some app that u shouldnt. happened to me too 2 weeks ago and i had no sim so signal , i couldnt see my imei, etc. if that doesnt help , then reinstall ur rom or install a custom one. I mean maybe u must be sure to check if u deleted some system app that u shouldnt. Since u have double checked with other sim , if its not from an app , then the above thread is right, the owner could have reported the phone stolen

There have been some problems with this, but normally due the the RIL on CyanogenMod-based ROMs. I would suggest that you find the time to either reflash v10h or upgrade to v20A/B/C (as appropriate for your region) and see if that fixes it for you.
you still havent mentioned anything about gapps. this means you checked and you are sure that they are fine ??
So I have tried flashing software V20A using the LG software updater and now all I get is the phone booting into 'S/W Upgrade please wait while upgrading'
I can get into any other screen, despite pressing all combination of buttons together.
I have attempted reflashing back to V10H and try and get it back to how I had the phone. No luck there
And also tried again with V20A. No joy.
Is there anything else I could try?

http://forum.xda-developers.com/showthread.php?t=2780274&page=165
Received a warranty replacement for my HTC One (M7), which is a brand new handset running 4.4.2 and sense 6.0. The wifi on the device will not turn on at all. It just looks like it is continuously trying to start with no way to stop it. My last two of the same phone had hardware issues and I am hoping for an easier fix than sending it away again under the warranty.
So far I have tried:
- Factory reset
- Tried to boot to recovery to clear the caches, but it just goes to a black screen
- Toggling between Airplane mode (as suggested on some forums)
- Tested setting up as a portable hotspot. It goes through the steps and completes, but then just says that the feature is still switched off
Any help would be appreciated. I would rather not flash a custom rom, but am open to the idea if needed. If this is a hardware fault and needs to go away under warranty I would be better to find out now and send it off sooner.

Any help would be appreciated. I would rather not flash a custom rom, but am open to the idea if needed. If this is a hardware fault and needs to go away under warranty I would be better to find out now and send it off sooner.

Have you ruled out the possibility of it being your Router ?
have you tried to get wifi in different areas ? If it never connects to wifi anywhere it's most likely a hardware issue. I have never had a wifi issue with dozens of different software configurations. Unlocking the bootloader may void your chance of sending it back
If you dont want to send your phone back, i`d try to make a factory reset first. If that does not solve your problems, s-off your phone, install a custom recovery and flash a custom rom from xda. If that makes no difference try to flash a different firmware (that matches with your phone!!).
I hope that helped.
Good luck and if you have any questions, feel free to ask in this thread. :good:

In the house we have multiple tablets, computers, other phones, Chromecast, etc etc. My previous HTC Ones never had any issues with my wireless. The issue remains that the wireless on the device will not turn on at all in order to search for or connect to the WLAN. It just says "Turning on.." indefinitely.

I was hoping to avoid installing a custom rom this time around (had the stock M7 Google rom on previously). I may try a new rom just to rule out hardware issues. It's sounding more and more like Im going to have to return the phone...
