Galaxy tab keeps rebooting - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hi all,
I have an issue where my tablet keeps rebooting. Unfortunately it works for a few seconds and then reboots. I have some important files so a factory reset is not really an option... Can you please guide me to at least how I could recover the files?
Thanks in advance guys.

Bad E-MMC

That is definitely the e-mmc problem. I have experienced the same thing and it required replacement..
your e-mmc is damaged, therefore your Rom reads the data but it cannot write into it, so it reboots itself.. you can no longer reset your tablet. .once factory reset is completed and it reboots.. all applications remain , within couple of seconds, it reboots all over and over..
Consider buying a new mainboard... replace and flash..
hope it helps..

boot into safe mode. it will allow you to recover your files and save them on a laptop.
you can search for how to boot into safe mode on google. i had a similar problem

safe mode won't work because the emmc chip is set to read only. so there is nothing you can to get you files back.

Copying files is still possible even when the chip is set to read only

People care but if they don't have an answer for you it's not much they can do, tried pulling the battery I guess and using CWM to reset battery data and reseting to factory defaults etc?
People arent answering because there is already a guide on the forum explaining exactly how to fix this.

I have tried about every single option in the CWM menus, and I've tried pulling the battery at random times.
None of them worked.
I'm now going to remove Arch Linux from my PC to make room for windows XP. Sorry for my previous outrage.
Next time remove CWM from your phone before updating...
I just installed windows XP and followed the guide to the letter. I am now stuck with the firmware update screen. How do I get rid of this?
Flash rom
I,ve managed to flash the rom with the original v10D but itÅ› still booting in clockwork recovery mode pfffff
These phones really are hard to unbrick.
Tell me please how to exit Rekaveri. Reloading and pulling the battery does not helps, it means everything? brick?

If you're stuck at the "updating firmware" screen like me, you're simply ****ed.
http://forum.xda-developers.com/showthread.php?t=1197108
use LG vip service.
I just called them, they said they'd "assess" my situation and that they'd call me back to tell me whether they'll replace it...
restore
Hi,
I have managed to restore a backup image but he is still booting in clockwork recovery what am i forgetting ????
Sincerely Snellie1972
Recover
I have recovered the phone with clockwork recovery with stock file
Optimus 3D 10D pre-rooted CWM restore but still it goes in too clockwork recovery at boot
What am i doing wrong ????
Thanks in advance
snellie1972
Unfortunately I was also able to get passed the clockwork screen but the phone is stuck on the update just like anybody else. I contacted the store where I bought it from and they sent me a prepaid box already to send it to them for repair/replacement.
As everyone says, at the moment it's not possible to recover from that state, sorry snellie.
If you still get the clockwork, then just follow these instructions but even so, you wont get passed the software update screen.
Flash
I have managed to flash using first de KDZ tool from LG en after that i have used te LGMOBILE update tool and just put in my imei and serial and it was downloading and restoring my phone so far so good but when it was Finished without any error it is still haging on update software ...
I don't understand why it is not going any further
Greetz
snellie1972
It's almost as if this firmware update screen is fake and an indicator for LG to see you ****ed your phone up.
Is there any known hacker even working on this?

[Q] Stuck on ASUS logo

Hello everybody,
I hope that someone can give me some advise to get my tf300t up and running again. I wanted to install cm10.2 but I wanted to install CWM first.
I unlocked my device first with the unlock app v8 from asus.
I tried to install CWM the first time but it did not work.
I went back into recovery mode but I wasn't paying attention and pressed wipe userdata
Now my tf300t only shows the ASUS logo and the text that the device is unlocked. I can't get back in recovery mode anymore. Is there a way the restore it back to default?
I hope that someone can help me out.
Thank you in advance for your time and effort.

Can you get to the menu with the recovery options, boot android, USB, and wipe data? You can use fastboot from there.

If you cant get into there, you cant really use fastboot. Unless you made NvFlash Backups beforehand, I don't think there is much else you can do, since the recovery isn't working either.

I've spent a lot of time searching and it seems like that's it...
I'm on Asus screen, I can reboot it by either holding down pwr button until it reboots, or using reset switch with a paperclip. vol - does nothing, just reboots to asus screen...computer sees nothing. vol + goes into APX mode (blank screen)...computer detects with correct drivers. I've tried draining battery completely...disconnecting battery for a few days...same result.
If I had to speculate...maybe at some point someone will figure out how to use another's backup files and push them to the device in APX mode.
I've looked into replacing the motherboard...and have seen some for as low as 50$ on ebay. Personally, swapping them would be easy...but some may not have the caviler attitude with hardware swapping. Just gotta get the wife to agree to spend the $.
I'd die for a free fix, the kids really miss playing with the thing

[q] opo qhsusb_bulk

Hey guys
So a couple of days ago I was browsing on facebook when suddenly my One froze and rebooted. After that I suddenly didn't have any connectivity.
I figured I might be able to fix this by rebooting the phone, but after the reboot the phone worked for two seconds and then froze, restarted etc.. It keeps doing that.
Now I looked up if this was a common problem and it is, there is also a fix for it. The fix requires fastboot, but I can't get fastboot to work because I get the QHSUSB_BULK error on my PC.
This usually indicates a hardbrick but my phone still starts up, I can also boot into recovery, I just can't use the fastboot.
Is there anyone who can help me?
Thanks in advance.

I believe there is a way to recover from hardbrick by installing colorOS and reinstalling CM.

[Q] OPO Boot Loop/Hang After Drop

I accidentally dropped my OPO face first from about chest height earlier today. The screen didn't break but now my phone is acting weird.
First, it was okay but after a few minutes, it hanged up and was on a boot loop. I tried a factory reset but now I'm unable to get wifi (wifi button is off with a orange square around it) and the boot loop and hanging still persists. The phone does heat up and seems to go out of the loop if its cool enough. Hangs up if it gets hot.
Any help on fixing this? I'm going to try a fresh install in a few minutes but I'm kinda feeling this is a hardware issue already.
The fact that it still does it even after doing a factory reset is concerning. Try doing a complete factory restore as per this thread and then also try this. If both fail to resolve the issue i suspect your hardware has been damaged and i don't see you fixing the issue one your own unfortunately.
Yeah, unfortunately I did both already. Installed stock build and the Audio FX fix. The Audio FX bug is still showing up though. Not sure if I have done anything wrong in replacing persist.img

You could also try flashing this. Though i think its unlikely to fix the issue, you don't have anything to lose at this point...this also re-flashes the reserve4 partition.

Just an update, my phone is now dead. After rebooting several times this morning, it suddenly lost power. Not even charging helps. No response from power button and can't even fastboot. I guess the main board got affected when it fell and fried itself up in the process.
Crap. I'm really sad about this..I'll probably try opening it up and see if anything got dislodged. You think that's a good idea?

I sorry to hear that bro, its a bummer. You might as well open it up yourself and see if you can find anything obvious wrong with it, or you could try and get in contact with OnePlus and find out if they can do a repair of sorts, but i wouldn't get my hopes up on that though.

Well, it seems there's power. The phone is slightly hot when touching it. I tried plugging via PC and Windows recognizes there's a USB device although after trying to install drivers, it prompted me that the device was not recognized. Not sure what to do at this point though.

My phone is back but still boot looping. Would installing other ROMs solve the problem? I won't be able to RMA this so it's not an option.

It could perhaps, but lets start here: Can you boot into fastboot mode? If YES does it reboot itself while in fastboot or is it actually stable as in it stays in fastboot?

It's actually quite stable. I had never seen it reboot when in Fastboot. It's also worth mentioning that if I'm in Recovery Mode (TWRP installed), the phone also doesn't reboot.
I also noticed that ever since the drop/boot loop/hangs, my phone reboots very long (around 2-3 minutes it it does boot into the system; which happens less frequently than the boot loop). Before it took probably a minute at most to reboot.

Another update. So here's what I found out. My phone needs to be super cooled for it to work. I tried putting it in front of the air conditioner. If it's really cool, WIFI works. When it gets slightly warm, my phone hangs up. When it reboots, I lose wifi. After that, if I still don't cool it down, boot loops happens.
I'm not sure what's happening but it seems that it's an overheating issue perhaps?

Well that is possible, i suppose. Maybe the heat-spreader moved away ever so slightly of the CPU, or isn't making good enough contact with it anymore which would lead to it not properly dissipating the heat. Unfortunately that i wont be able to know.
Lets assume that this is a software issue for now. Have you tried this yet by any chance ?
If not it is definitely worth a shot. Before flashing it i recommend clearing cache partition & dalvik cache in TWRP first then reboot into bootloader mode and then run this as per the READ ME file which is included.
There are essentially 3 batch file you need to run and it will recreate all the partitions on your device etc.
PS: You need to register on the OnePlus forums to actually be able to view the thread.
PPS: If for some reason the download link is bad let me know and ill mirror it for you on my dropbox.

Try booting in safe mode. If it still reboots, then flash a factory image with fastboot. If it still reboots then, you've got a hardware problem.

If you flashed a factory image and it still does it, then it is likely a hardware issue.
Replying to your PM- Boot into safe mode by pressing the power button, and when the reboot menu comes up, press and hold "Power off" until the option to reboot to safe mode pops up. Then just hit OK.

Keep it that way?
Check with a recurring problem?

Safe mode boots your phone without any 3rd party apps or non essential software. It basically only loads the stuff your phone needs to run which will help to eliminate any apps as the culprit. Yes you'll still get calls, but any apps you use won't be accessible. It's not something that's meant to be used all the time, just for troubleshooting. So, if you still get reboots while in safe mode, that means you either have a hardware problem, or a firmware glitch. But since you said you already flashed the factory image that pretty much rules out the firmware, leaving hardware as being your issue.
