G3 won't factory reset after bootloop - G3 Q&A, Help & Troubleshooting

So, i bootlooped my device somehow, and now I'm trying to factory reset the damn thing. problem is, I go to the recovery screen, where I can choose safe mode, clear cache, and factory reset. I click factory reset, and the little android alien pops up for 1-2 seconds, and then it goes black and the phone restarts. In other words, its not letting me factory reset for some reason.
Please help asap!!

wtf? I never installed a custom ROM or anything. just a custom boot animation and a build.prop edit, and one of those two things boot looped my rig. when i try to factory reset via the hardware buttons, it restarts after 1 second of trying and goes back into the bootloop. i try ever different setting on the recovery screen, and they all have the same result (either safe mode, or delete cache)
how else can i factory reset so i can get my phone back'??

Stuck in Bootloop after entering a wifi password

Hello Guys,
since 2 days my phone stucks in a bootloop. I entered a wifi password, then my phone starts to reboot immediately. the lockscreen appear for just 1 sec and then the phone starts to reboot again. Im Using Android 6.0, unroot, usb debugging disabled, closed bootloader and no custom recovery. I can enter the download mode and the factory reset menu. I can reset my phone, but i dont wanna lose my pictures on the internal storage. Is it possible to save my pictures? Or how can i restore them after a Factory reset?
i also tried to reinstall Android 6.0 with the LG Flash Tool 2014, and did the installation without the factory reset, but it doesnt helped.
i hope someone could help me.
Thanks

A factory reset might fix it. This is why you should have stuff like that backed up.

Have you fixed it yet ?

Wrong pin bug resulted to bootloop after factory reset

Hey guys,
The tablet wouldn't recognise my pin. It happened once before but a simple reboot fixed it. This time nothing I tried worked (switched accounts, restart, wiping cache partition). So after a lot of consideration I decided to go to Recovery and do a factory reset. After it finished, it automatically restarted and since then it's in a bootloop.
All the instructions I've read about factory reset say you need to manually reboot after it's finished whereas mine rebooted by itself. Do you think that's why it's stuck now? What can I do?

Black screen LG G4 H812?

screen went black, and now I cant do anything. Phone boots normally. LED indicator at the top shows that the phone is booting fine. (the top half also gets super hot for some reason?)
Any ideas on how to get it back? Or is it bricked?

If you are still on the stock recovery originally installed, see if you can boot it manually into Recovery mode. If the screen shows in Recovery mode, chances are you have developed a corruption from something you installed etc., not bricked it. You can try wiping Cache when in Recovery mode but I suspect you will have do a Factory Reset from there. If you have installed a custom recovery and have a known good backup, you could restore that or re-install the rom in a clean flash (wiping Cache, Dalvik cache, System and importantly, format Data > Yes.
Failing that, you may have to replace the screen or send it in for repair if it is a hardware issue.

I just flashed a 100% stock rom with putting the phone in download mode and using LGUP, same problem... Guess it's bricked :/
It's not even worth it to repair, I just wanted to see if I could fix it myself
Thanks anyways

If you were able to see the download mode screen, it is more than likely not a hardware issue. You have to do a full wipe (preferably, Cache, Dalvik cache, System and Data (best would be a format of the data partition), to get rid of any data/rom corruption that may be causing the black screen issue. If you did not do this, try that first, making sure you re-install the same original rom that the phone came with, before junking the phone.

samsung s4 tablet t837t boot loop after flash

Hello everyone. I'm trying to flash a samsung s4 tablet t837tuvs4ct13. The flash goes normal, but after the tablet restarts it goes to a blue screen that says erasing for a split second, then goes back in to the boot loop. I do perform the wipe cache and factory wipe before each flash. The device was in a boot loop when I got it and factory wipe did not fix it. Does anyone have any advice on how to fix this problem?
Thank you in advance for any help.

Most likely the device was locked by the person you got it (??)
Without the correct pin, password, or account details,if factory reset protection (FRP) has been set in an android device, then the device is almost dead..
First than all : The most important part is to allow "adb debugging" from developer menu on your device ! If it is enabled there may be a solution ...
