GT-P7500 got stuck in recovery mode - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

My tablet was running fine, I was chatting with my friend using the facebook app, suddently everything froze up, so I pressed and hold the power button to force re-start the tablet but got into boot loop instead. I then went to recovery mode, and here comes what I find really weird. I can't do anything in recovery mode. Try to wipe data, the tablet gets stuck and restarts itself. Try to wipe dalvik cache, same thing happens. Try to restore a nandroid backup, get stuck at restoring data. Now the tablet is still in bootloop, and stuck at the CyanogenMod boot logo. Yeah, it just freezes there for about 5 minutes then reboots itself. I'm not new to CWM recovery, I've flashed hundreds of Roms in my life but never seen anything like this. It seems to me this is hardware related, I don't know. Has anyone here faced this issue before? Any idea how to fix it? Thank you.

Have you tried download mode?
Try to recover it in Odin. If it fails to flash i'm pretty sure you have a bad nand.

[Q] Exhibit II - Soft brick? Persistent boot loop issue...[SOLVED]

I'm having a problem similar to many people but from looking all over these and other forums, nothing is working. It started when I turned on my phone and while the splash screen was still on, plugged it into my PC to charge, boom, boot loop ever since.
I was using the Peach Sunrise kernel, and first tried to re-flash the rom...nothing, still bootlooping.
Data wipe...still boot looping.
Flash to stock via ODIN...nothing - it still does the bootloop after the reboot.
Now I don't have CWM anymore and I can't flash it because I cant' access the internal SD. Any ideas? Help is much appreciated! Thanks.

Okay, sorry to jump the gun, I managed to re-install CWM with Odin, but that still doesn't get me much further that I already was.

Lenovo A820 won't start

Hello everyone!
I have a Lenovo a820 with Lambda rom 2.4v.
I'm using it for a couple of weeks now with this last version, and everything was fine, until suddenly it froze for a while, I unplugged the battery and plugged it again, and what I notice was that the phone restored itself to when after I installed the rom (meaning all of the apps were gone).
So I tried going into Google play, installing some apps back, and I get this error -24 telling me its unable to install the app, happened with any app I tried. so after trying a few suggestions from the internet about this error, I decided to format it and install the rom all over again.
I go back to recovery mode with CWM, try to install the lambda rom like I did before, and in the middle of the installation it reboots and gets stuck in the "lenovo" screen like when you boot it. so after waiting for a long time I unplugged and plugged the battery again, went through the procedure again this time it installed it 100% rebooted so it would boot with the mod, and again, it freezes at "lenovo" start screen unable to boot.
went on recovery mode, formatted system, data, emmc, everything... I think that's the issue here. but im not sure.
After that, tried to install again with the same problem.
The problem now is. it won't even start I press the on/off button to start it normally, and I dont even get the "lenovo" screen, I tried going into recovery mode and no luck.
It's like the phone is dead! Although I have another Lenovo A820 and I tried the battery, and its 60% so that's not the battery.
Do you guys know any tricks? or any tools that I could use to get my phone running again?
I would appreciate it very much, any help you can give.
Matt.

[Q] Nexus 7 Stuck in Weird Bootloop

My Rooted Nexus 7 was working perfectly. Now I am not sure If it is Soft Bricked or something else is wrong with it, It was charging one day and I took it off one micro usb charger and put it on another Nexus 7 charger. I went back and turned it on, Now it was stuck in bootloop, I have seen bootloops before, but not like this. It turns on and goes to the lock screen, then after a few second it freezes then restarts. I have been able to quickly log in boot into safe mode but it still freezes and restarts, I made it to the app menu once and then it sad , Unfortunately Launcher has stopped, I have cleared the cache and dalvik cache and nothing works, I have bootloader version 4.1.3 and CWM version 6.0.1.9, I have tried to format tablet and factory reset with cwm recovery but when I turn it back on I still see my stuff and I still reboots, I have tried to restore from a backup from a while ago with cwm but it fails. I tried to use nexus toolkit but I dont remember my version and I cant check, I gave it a guess but It can not find my device when plugged in, even in recovery mode, It said something about fastboot but i think i did that but I am not 100% sure what it is, I need to get this workig again fast.

Ever see a factory data reset not wipe a device?

My mom has this old Galaxy Tab 3 that started randomly rebboting on her. She asked me to look at it.
When you turn it on it boots up to the home screen, and after about 10 seconds it reboots. I booted the tablet into safe mode thinking it's an app she installed. Safe mode lasted a little longer maybe 30 seconds before it rebooted. So I booted into recovery mode, and wiped the cache, and rebooted back into safe mode. Still rebooted after 30 seconds or so. So now I tried wiping the tablet, let's start fresh. First I tried erasing it from the settings menu when the tablet is running. No luck will not erase. So now I tried to wipe it using recovery mode. Recovery mode mode claims facotey reset successful. I rebooted the tablet and my mom's email is still set up. So I went back into recovery mode and wiped the tablet doing a full factory reset 3 times in a row before rebooting and EVERYTHING is still there. Has anyone ever seen this before? Is this a problem with the flash memory perhaps? Maybe the main board? Any advice on what's going on or how to erase this would be appreciated.

This is very weird.So,Let me get this straight.You tried to wipe the tablet and it doesn't wipe.Well,when In recovery mode the recovery doesn't care if there is a loop a symlink or anything that will have any other function other than to exist.It will remove it without a problem.I would say Try doing it from custom recovery otherwise it's not-software relatef.

I've tried in the stock recovery mode whenre I hold the power, volume up button, and home buttons. When you say custom recovery is this like a TWRP recovery?
Yeahyeaah

sm-t820 freezes after boot.

Hello,
maybe someone has suggestions on what to look next or how to determine where the problem actually is.
My Galaxy S3 Tab 10 has suddenly started to freeze after boot + ~1-2min. Even if I wipe everything it freezes even during the initial setup. It is possible to complete the initial setup in minute increments.
When it freezes there is nothing I can do, only Power+vol down for reset. Even to power off I need to press Pwer+vol- then boot it in recovery and then choose power off.
But if it's booted in recovery it can be on for a while and nothing bad happens. That let me think it is more software than a hardware issue.
Have tried to reinstall stock ROM, a few custom ROMs, all the same.
It has not been dropped or "watered" or some other abuse.
Any help?
Thanks!
