Ok. I bought this Galaxy Tab 2 7.0 from a friend for cheap because I thought I could fix it, but I'm running out of options. It's in a boot loop, but an abnormal boot loop. If it's unplugged, It will do the splash screen (Samsung) boot loop. If it's plugged in, either into the wall or into my computer via usb, it will do a battery (charging) boot loop. It's kinda weird. I used to have an Epic 4G and it happened damn near all the time, without the battery loop, but it would charge normally.
I haven't successfully gotten it to boot into Download mode.
If any of you have come across this issue, please feel free to help me out.
I also attached a picture of me attempting to put it in download mode. It reboots if I hit either VOL up or VOL down.
Thanks

Can you get into recovery? Also, have you tried unplugging the charging cable and getting into download mode with the cable unplugged?
I'm not sure how to get into recovery. With it unplugged, all I have to do hold the VOL Down physical button and ti will take me to a "are you sure you want to put the device into download mode screen". I apologize. I'm not to familiar with this device.
Edit: After I get to the screen where it asks me if i want to go into download mode, it reboots within 5-10 seconds, no matter which button I press

Hold power and Volume up (volume button closest to the power button) until the tab shuts off and reboots itself and then you can let go of both buttons. If it works, try doing a factory reset. Was this tablet rooted (or have a custom rom installed) in the past?

As far as I know it's been on Stock. My GTab ignores me holding the Power and Volume up keys at the same time and keeps the boot loop going strong.

No, his device is fine.
If your device bricked, but still showing Gtab2 logo on it, it's still fine. You need to flash to stock 4.03 rom via ODIN. (Not clockworkmod)
Warranty won't work if you have flashed custom ROM before.

He needs to be able to get into Download Mode to use Odin. He stated that he can't. When he tried to continue into download mode by pressing volume up (vol. button closes to power button) the tablet reboots. It needs warranty service.
Experiments:
Power off the tab completely and charge completely and press power +volume up for 10 seconds then release, also try to power off and press power+ volume down for 10 seconds then release do you see any screens
If it says do you want to enter download mode or so press volume up and see if you could see (downloading) try also the same with volume down instead of up
Try to connect to computer do you see any messages indicating connections
Also try to connect to kies and try restore or recover firmware from options of kies
You said it reboots after 5 to 10 seconds so try to open odin and try to go to download mode and when you press volume up try as quickly as possible to connect tab to pc while odin is open

There's other method by using OpenRecovery (OR), by putting OR on external SdCard,
but it seems the OR for Gtab2 is not developed yet -__-

OK relax take a deep breath can you reboot the phone using the power button can you turn off the phone. If the phone starts back up immediately turn it off again by holding the power button again. As soon as it shuts down let go of the power button then immediately push the power button and volume down for about 3-5 seconds it should get you into fast boot. If not try it again it could take a couple of tries. You should then be able to fxz. Holding the power button restarts the phone like a battery pull.
Thank you

I had tried that several times and finally Im in fastboot mode. I reflashed twrp and restored a backup, Im going to fxz just to be sure.
RSD Lite is working, the problem was a "Chunck error" download size too big. Thats the error message i got when trying to flash the moto x system.img.

sometimes you have to use moto-fastboot to be able to flash the large files. You can find it floating around the forums.

Hi,
really need help...I was about to sold my old HTC Sensation XE, rooted and had viper 5.2.1 on it - deleted everything from SD card, but wanted to be sure nothing remained on my phone so I made factory reset (i think I shouldn't to this)..
Now when I turn phone On it loads HTC logo, then Viper logo and restarts and then again HTC, Viper restart...
When I hold power button + vol.down nothing happens (HTC->Viper and restart) + all the buttons are flashing...
Did I bricked my phone for good or is there a way how to reflash everything?
Thanks

U must be doing it wrong or ur volume button is dodgy. Ur phone being in a bootloop should not affect getting into bootloader once uv pulled the battery.
I'm sure it was working before (my girlfriend used it a never told me she is not available to lower the sound)
why are bottom buttons flashing while holding power + vol down?

I dunno, mine does that if im in a bootloop n i try a hard reset. Dont worry. The vol button mite work but she mite just need to give it an extra push, no harm in cleaning it coz the sensations r bad for dust getting in there. K pull the battery out for a min n put back in then press and hold vol down (hard) and press n hold power button. U should get to bootloader, keep trying till u do. As long as u pull the battery out u should get there at some point.
Sometimes I also have to pull the battery out twice to make it go into bootloader. Just make sure you have enough charge in the battery too.
no luck... tried it around 20 times and nothing... communication via fastboot is not working..
so I guess there is no other way how to enter recovery as vol down and power
?

Hi there,
Kindly help... I successfully installed B512 on my TL10 using force upgrade method, afterwhich I changed recovery to TWRP 3.0.2 using mobopx v2.2, which was also successful. And then I installed SuperSU 2.46 via TWRP, then cleared cache/dalvik. But upon rebooting system, I get a blank screen, even after waiting for more than 15 minutes.
And so I tried going to TWRP (Vol+ and power), which was successful, in order to boot to bootloader, with the intention of loading back the stock bootloader via adb, so that I can force install B512 from my microSD card again. It seemed to install fine...
However, at this point, I cannot reboot to bootloader (Vol- and power) anymore, I only get blank screen. Trying recovery (Vol+ and power) doesn't work either. Rebooting normally gives me the same. I cannot by any means connect via adb now.
Is there any way to unbrick my phone at this point?
Thanks so much. Cheers.

The phone "doesn't want to turn off" bro. It has fully discharged, but as soon as I plug the charger in, it immediately powers up. When it does, now it shows the Huawei logo. But it's stuck there, and if I press the power button for a few secs, it will power down, but immediately power up again...

Let it get fully charged first. Then remove the charger and keep the Vol up and power button pressed for ~10 secs or more, and see where it takes you.

You seem to be in a sticky situation bro. Your recovery seems to be broken because in stock recovery Vol up + power should ideally take you to recovery and not restart. If you could somehow boot into fastboot mode then it could open up some options to bring your phone to life.
With no way to connect to the phone the only options left are the hardware buttons. I am sure you'd have tried them already, but just in case you have not, try the other 2 key combinations also, Vol down + power and Vol up + Volume down + power, for ~10 secs, to check if any of these either forces a factory reset or boots the phone into fastboot mode.

Thank you for this suggestion brother. I tried exactly as you described, however, the phone looks badly discharged, and while the screen was blinking/showing the red battery icon, it doesn't seem to want to charge. I waited around 5 minutes, but nothing seems to progress from here.
And so now, I moved the USB cable to a proper charger, and now it seems to be charging, with the LED light a steady red, and the screen the normal red circle with "0%" inside. It seems to be charging at the moment, although I really have to wait until it shows "1%" until I can surely say so.
One thing that's different now is that the phone hasn't turned on (by itself) yet. And at least this looks promising.
I'll let you know what happens in a while... Thank you!

Disconnect phone from USB.
Turn phone off. May have to hold power button down for 10-20 seconds.
Hold volume down button and while holding down hold in power button for about 3 seconds until phone vibrates, then release power then release volume down. Phone should boot into TWRP. Wipe "System" ONLY. Reboot system. If phone behaves as before, reboot into TWRP as before, reflash your ROM and reboot directly to TWRP (Recovery) again. Reflash ROM again and reboot system.
Report back.
Hy!
I tried it but it hangs on 1+ logo. Same while i tried to start in fastboot mode
tried so many times but nothing ... is there any JTAG solution or else?
So what you say is that if you completely shut down your phone and you hold ONLY volume up and connect it to your PC, nothing shows up? Not even QHUSB_Bulk in device manager?
no i only see the 1+ logo and than the charging logo. But my PC doesnt detect my phone

I tried 1000 times i also tried it on other USB ports and other PC but still the same
