Bought a used D851. It is stuck in bootloop at the t-mobile screen. When i turn it on, shows LG logo, then green android icon for few seconds, then again LG logo. After about 1 minute, the white t-mobile screen shows up and stays for about 45 seconds and then screen goes black followed by white t-mobile screen again.
I have tried stock recovery with lg mobile tools. Also tried lg flash tools and everything goes fine, at the end, i get blue reset status 3 screen. Upon reboot, its back to boot loop. Also tried factory reset. With lg flash tools, when i choose "Board" then after reboot, it logs on to the minios menu but the screen is completely unresponsive. So when i again flash with "upgrade" selected, it flashes fine but continues the boot loop.
Please help.

As the title says, my rooted LG G3 D885P (brazilian version of ebay) works fine for around a minute. Then the screen freezes and it restarts the phone. 3 Different screens pop up after restarting. A black screen, a green and an orange. The Black screen says kernel crash with the options to reboot or go into dload mode. The green screen says apps watchdog bark with the options to reboot or go into dload mode. Sometimes a different green screen says TZ Crash. I don't remember what the orange screen said but it was similar. I downloaded the stock rom ( .kdz file) and used lg flash tool 2014 to boot it. The phone turned on like the first day i got it. Asked me what language and all the initial settings. All my data was gone. From what i can see, the phone doesn't appear to be rooted anymore but it still crashes after a short time. Can someone please help?
Hi,
Today while browsing my stock LG g4 (h815) suddenly rebooted. It showed the LG boot screen for a while but then ended up with a black screen. The power button does nothing. If I remove and insert the battery the power button works again, but I get the same result.
I can boot to (stock) recovery OK and if I connect it to a pc it shows 100% charge. I tried using recovery to reset everything but no change.
I am on holiday so can't easily send it in for repairs. Any ideas? I do have a Windows tablet pc with me with ADB on it.
Search "bootloop" in G4 forum.
Warranty is the only solution.
But this is not a boot loop? It seems to boot normally and then goes to a black screen, it doesn't reboot. I direct about the boot loop but from the videos I could find it looked like it kept booting.
I guess I was wrong trying to start it today it boot looped a few times before the black screen. Guess I will try disabling the big cores so that I will at least have a phone until I get home.
My lg g3 is stuck on demigod kernel crash. i cant use any flashtool because download mode goes directly to 9008 mode.
i already used boarddiag by willcrack to one by one flash each files. including userdata with around 12gb lol. the whole process took about 10hours. but the same result. sometimes it will boot but it will constantly hangs. it goes bootloop sometimes. sometimes its stuck on lg logo without animation and no led. sometimes with led and sometimes will go to lg boot animation but still stuck. sometimes the status bar will appear with only time at 00:00 but the rest is black. im loosing options because even boarddiag flashes all the files fine but problem persist. i can access recovery. but factory reset does not help either
Hi,
I recently installed flashify on my LG G3. It was sometimes switching off during use and I thought to try and install new ROM.
Now however, it does not start. Going into recovery mode returns an error 'Secure boot error' and leads to black screen with red/blue LED fash. Going into download mode causes a message to appear in small text in the middle of screen 'Recovery mode' (not full screen like normal) but then resets after 8 seconds and goes to black screen.
Hence using LG flash tool to flash stock ROM is impossible because it resets itself after 8 seconds.
Please help!
Thanks.
My htc one m9 is bootlooping. I just installed version 18 of the unofficial liniage os rom, and it worked fine, I went through the setup and everything and was using it for some days. Now I try to boot up my phone and it just keeps bootlooping with the green htc logo and red text. I tried going into the TWRP custom reocovery but all it does is get to the silver htc logo for some seconds, reboots again to the silver logo, then the screen goes black and it does the boot loop on the green htc logo screen. So I cant et into the main os and the recovery, what can I do? I don't care about the data on the phone I jsut want it to be functional again.
I really hope I didn't skrew myself completely and made a brick.
Edit 1: I thin I remember attempting to get into the recovery with a combination of volume and power button on startup, because getting to it via bootloader didn't work for some reason. I pressed Volume up and power button to see if that would get me into the recovery, but it booted the phone to the green htc logo without the red text. then it stayed on for some time and rebooted into the green htc logo with red text. that is when it started bootlooping.
