I have the V500 on CM12.1 unofficial. Everything was fine and then I went to do a backup in TWRP. Then I looked at the restore menu but didn't do anything. I backed up to my SD Card. Then I booted back into the system, but all that came on was the back button and the notification tray and status bar. The background was black. No home button or multitask button. So I reset it a few times. Eventually I could get into the tablet but when I clicked on a app nothing opened. I then reset it again and it kept coming on with that partial screen. I tried to boot into recovery to try and restore the backup but ADB was locked and the button combination didn't work. So I decided to flash back to stock using LG Mobile Tools. Eventually I could get into download mode but when it got close to finishing to flash the software it stopped and gave me an error. After doing some hard reboots it eventually flashed the software because it would boot into the LG screen. But it was stuck in a bootloop and I've read that in order to fix that you need to do a factory reset. So I tried to boot to recovery but when I pressed and held down volume down and power nothing would happen. Sometimes it would flash the LG logo for a split second. Eventually after a lucky try the LG logo stayed on and I could boot to recovery and do a factory reset. Then everything was back to stock. But when I turn off the tablet it won't power back on unless I plug in the tablet. Battery is fine. Regular battery life it just won't turn on when I power it down without being on the charging screen.

i have a pretigio multipad 3270b. I was busy putting music onto my memory card when all off a sudden my screen went blank and when it came back on it was stuck on the prestigio screen the whole time. I tried all the button combination i can think of to enter the recovery mode.or clockwork mode to do a factory data resent but i don't seem to get into it, keep going to that one screen. I can get into the device at all. tried the reset button as well and still nothing. Please as anyone know how to get into that recovery mode or clockwork mode to do the factory data reset it will be truly appreciated. Thank you

Johan, I have a similar issue with my Huawei U8652 (2.3.6), I just removed the battery for a few seconds, put it back in turned it on and it worked as normal. But I too now can't do a factory reset now, phone works as normal until I turn it off and plug it in to charge or to the PC. Hopefully we'll get a solution to this, I'm thinking I may have to flash a default ROM but not sure how since my boatloader is borked.
So I was stuck in a similar mode (recovery download mode) yesterday, it only show Android robot with spinning gear on his back and a scrolling progress bar. I turn it off (Power + Vol Up) and then no matter what I do, just power or power + vol down all just go back to that damn robot.. Fastboot, adb won't work.. It show up on the computer as HTC Android Phone USB Device in the DVD/CD drives
It refuse to get out of that for hours.. I finally give up and I leave it running and walked away.. somehow when I got back (around 2 hours later) it is booted back to normal and asking for new setup. So I thought is working. So after messing up the initial setup, I when and try to factory reset it this morning.. and again it goes back into a similar mode, but this time it have the word Erasing under it. However this time it won't leave the mode even for 3 hours +. Anyone know how to get it out of that mode and maybe interact with Fastboot or Recovery or bootloader or something
When it is working... I could into booloader and stuff. The phone has been modded to play edition, S-off and bootloader unlocked...
However whenever that happen, if the phone is off but plug into a computer, it show up as QHS_USB_BULK. and then usually turn on and get stuck on that robot again... Also if I just keep pushing up an then power it will say formatting and then backup recovery log and then all the spinning gear and progress bar just stop
I don't get this thing. Please help
So I managed somehow to kick it out again (after waiting for a long time).. but wanted to convert the GPE back to original. Was following this http://forum.xda-developers.com/showthread.php?t=2733523 but before I could go back into TWRP to load the new rom, I accidentally hit factory reset and it got stuck in the HTC version of that same screen. This time it have one extra line Backup CW Package.
Again can't get into the bootloader.. just stuck on this boot loop.. god damn..
Here is how it looks like

A few weeks ago, my phone rebooted and it was stuck rebooting to the att logo. I was on the road and was unable to use my phone. In frustration I tried to do a factory reset from the recovery mode.
It wiped system as its supposed to, but I was still stuck booting up to the logo screen and freezing there.
How to factory reset completely : Warning! You will lose all apps and data on phone as if you were reflashing with odin.
Boot into recovery mode (volume up + home button +power) select apply update from adb. Once started, just put your phone down and wait. It will take a little while. Then it will time out and completely wipe and restore your phone to factory.
Proceed to setup your phone as new.
Hey, I installed a new battery in my device, this worked fine until earlier today where it randomly went into a bootloop. Simply keeps looping the white Google logo.
I have put the old battery back in, still same issue.
I have also attempted to restore it to factory settings by holding the power button and both volume buttons. However I only get 3 options: Start, Reload fastboot, Recovery and Turn off.
Recovery starts the bootloop again... what can I do?
You probably should try disabling two cores by flashing 4 cores boot.img...

Hello everyone,
Yesterday when I was going to use my tablet I noticed it was off, but minutes before it was on, so I tried pressing the power button and nothing happened, plugged the charger in, nothing, no signs, it seemed bricked, so I tried to power through download mode and it worked, after that I pressed volume down to cancel it to start normally, the first samsung logo showed up (that one that says the model and stuff), but it was there for really long, i left it running and after 5 mins or so it changed to the pulsing blue samsung logo, left it there and about 30 mins later it was back to the 1st samsung logo again. I also tried a soft reset and booting to safe mode, didn't work either.
This tablet has no custom rom installed (I think it is on stock 4.4.2), the only thing different I installed is TWRP and root, years ago, but I cant boot to TWRP through the vol up+home+power, it doesnt work, tbh it never worked since back then, the only way I found to boot to twrp was thru "adb reboot recovery" using adb, which didnt work in download mode, I want to be able to backup some data before flashing it with Odin, so here are my questions:
1- Is there any other command I could try to force it to boot to recovery?
2- Is there any way to backup data via download mode on this device?
Thank you for your attention
