Hi everyone, new member. Recently my g3 got in a bootloop so i hard reset it. Everything seemed to work fine but after a short time the device used to get stuck and restart. I followed a guide how to revert back everything to stock but something went wrong and the device got stuck on MiniOS and then Reset Status 2.
i tried to fix it by flashing it with .kdz file but for some reason now when i turn it on it says: Secure booting error and the screen turns black and the led starts flashing red and blue.
I cannot access download mode cause it goes straight to the lg logo and black screen but u can access recovery mode. i already tried a hard reset but its no use as the device gets back to the black screen.
Any help would be immensely appreciated as this is my second g3 in 4 months and im tempted to throw it away.
Thanks and good day
Post your device model variant (D850, D851, D852, etc.). Also check out these two threads...

My sons LG G3 D850 Will not boot after the LG logo screen it goes black and will not boot. He's been on Validus for over a year. I have wiped Dalvik, System and Data then flashed the rom and google apps. It boots the LG logo screen then it goes black. I have to remove the battery to get into recovery again. Please help!!
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
Hey everyone ,
I have an LG G4 (h815t) Hong Kong variant , the device is on the stock rom 5.1 lollipop. It had the bootloop issue but i managed to fix it thanks to XDA (u da real MVP) , however after a couple of days the device suddenly powered off, i tried to power it on again but no luck what so ever,so i removed the battery then pressed the power button for 60 seconds (as it was written in a thread), then i put the battery back again & powered on, this time the device booted on to the LG logo i thought the problem is now solved because even if it was on a bootloop i already had the solution for that, but it wasn't even a bootloop, the LG logo showed for a brief then it went to a black screen! (awesome right? t:laugh::crying: ). i have tried to factory reset the device after that, i booted to recovery successfully & confirmed that i want to reset the phone but after the confirm the device went to a black screen on again! tried to get the device to the download mode & I've managed to do so after a couple of tries , then i tried to flash a kdz using the LG up tool but after i hit start to begin the flashing the percentage just get to 4% then the device somehow exits the download mode to a black screen & the LG tool reports an error. So now I'm stuck sadly :crying:
I've seen a solution on XDA in which i use an SD card to boot from to the download mode (as my internal storage could be corrupted),i boot from the SD card using a (single image.bin) file, but the author in that thread included the single image file to a specific G4 variant & of course i couldn't find the single image.bin for my variant (H815t). so here am i again stuck
-ANY HELP WOULD BE VERY VERY APPRECIATED.
- sorry for prolongation
- excuse my English, it's not my native.
