Hi guys i need some help!
Last week i got the new LG G3 its fully stock with Android 4.4.2 after reading some cool stuff about the new Android and the dalvik vs art battle i changed it on my LG G3 from dalvik to art. Everting was running smooth but after a few app updates and one LG update some apps broke and the phone started to reboot and reboot and reboot till at the point i am now.. stuck at the bootscreen. I tried everyting but it even crashes on the charge animation when the phone is off. i cant get it in to the hard reset or download menu the boot animation does not even start. The best i can get is turning the phone on and then put in the charger after a few hours fast boot appears in the top left corner and thats it.
Can anybody help me with this problem?
Try force reinstalling sw using lg suite or lg flagshtool. Remove the battery and put it in, don't power up yet. Hold the volume up button and plug in the cable connected to pc. See if that gets you to the downloading menu.

D851 here, When ever i switched from cloudy 2.5 to blisspop 4.0 and after wiping everything i flashed a various of radios bootstacks and etc to make it boot after many failed attempts to boot ( it boots up but after 4 or so seconds after the lg logo the screen turns black and doesnt turn back on until after i pull out the battery) it worked after i flashed the rom WITHOUT a custom kernel so naturally i booted up just fine and thought maybe now i set up everything on my phone and tweaks i should go back and flash a custom kernel i used to use (777 r16) but then it gave me the problem i faced before the black screen after the lg logo no kernal would work. THEN another problem arised similar to the freezing on the black screen randomly during a usage thru my day the phones screen would be unresponsive animations but touch wouldnt work and i know its not my screen cause when i flash back to cloudy it works fine the freezing happens at least every 5 mins. someone halp?
also this happens on any aosp rom
The following issue only happaned after installing CyanogenMod. The screen would turn itself off. Upon pushing the button to turn the screen on and trying to unlock the device, the screen would shut off again. After a few tries if you were lucky the device would unlock and you could work with it. Sometimes only a reboot helped. I then installed a modified version of CyanogenMod which still had the problem with the screen but it happaned less often.
Right now I am on v50030b (Android 5) which I didnt get officially but through here. Now the problem with the screen still happens occasionally. It is still annoying to the point that I think my tablet got somehow broken after installing CyanogenMod, but that cant be, can it? Does someone else have the problem with the screen shut off?
I set the screen to never shut off and when it happens i dont have any fingers on the tablet.
Any clue what the problem could be or even can offer a fix?
Thanks in advance!
Are there any TOTs available for the V500? TOTs flash more partitions than KDZs. On my VS985 G3, I was having problems no KDZ would solve until I flashed the TOT we have, now everything back to normal no matter what KDZ or ROM I flash. Just an idea.
Hey there,
I recently tried to upgrade to Nougat 7.1 by flashing Lineage 14.1 (latest Nightly) or Resurrection Remix 5.8.0 / 5.9.2 via TWRP 3.1.0-2. But somehow I can't get the system to work.
At first I went from Fulmics 6.9 to Lineage. TWRP -> Factory Reset -> Flash ROM -> Flash GAPPS 7.1 Pico -> [1st attempt Reset Cache + Dalvik] / [2nd attempt: Factory Reset] -> Reboot. Same procedure for RR 5.8.
After flashing the boot animation appears for a while and then, finally, the screen turns black, then reboot. When the screen is black I can still push the power button and hear the wakeon sound. But the screen is still empty. At some point I managed to get to the first step of system configuration (language selection) just by waiting one or two minutes. But on the next step the screen tuns black again and eventually freezes. Sometimes I can even see the status bar and change the volume bars for example, but the installation process somehow cannot initialize properly. Most of the time the system just turns black, freezes and then reboots sooner or later. I tried different builds of RR (5.8.0 of 2016 and 2017 as well as the newer 5.8.2) and Lineage (13.0 / 14.1) but the issue is always the same.
On my first attemps - coming from Fumlics 6.9 - I even had problems with the modem. But after switching between 30B and 21C flashing ROMs (7.1 in particular) went mostly fine.
In the meantime I have even performed a full reset via LGUP / LG Flash Tool 2014 to D85521C_00_1204.kdz, Android 5.0 LP with Baseband 13.2-00002 (modem 21c). After rooting with Kingroot, applying TWRP with AutoRec and upgrading to the latest version (3.1.0-2) I tried the whole thing again.
Flashing Nougat RR / Lineage, Gapps, then Factory Reset and Reboot. The issue is still the same... blackscreen, freeze, reboot. Also flashing MR_Bump.zip after the Nougat / Gapps makes no difference. When applying the .zip via TWRP, the system suddenly shuts down and reboots, then the same Nougat bootloop as mentioned before.
Interestingly it isn't even possible to flash back to Fulmics 6.6 after trying a 7.1 Nougat version. When flashing the system just shuts down, then reboots. The ROM won't install. Other MM ROMs have problems after trying to flash Nougat, as well. For most of them I get the same bootloop / freeze phenomenon.
So the only chance is to completely reset back to LP 5.0 via LGUP / Flash Tool 2014 again...
I am not really sure what is going wrong with the system. But generally speaking LP and upgrading to MM and its variants appears to work fine.
Only trying to flash Nougat leads to perpetual bootloops with any ROMs.
Is there any chance to make Nougat run on my D855?
Anything else I could try to fix the issues mentioned above?
Would be grateful for any help!
Edit:
After installing another 6.0 Marshmallow yesterday I oncemore tried flashing two other Nougat ROMs. The first one was AICP, the second crDroid. When flashing in TWRP I noticed that there was a basband incompatibility again. The ROMs required the 21c, which was already installed (by the lastest MM 6.0) but still marked as unsupported. After that I tried flashing Step-hans 21c in the first place and finally got the two ROMs to install. However, after the unconditional flashing procedure I always got two lines of an "Unknown Command [log]" error...
AICP just gave me the black screen after the boot animation again, but suprisingly crDoid booted without any issue. At least I could make it run normally for one or two minutes. Entering the menus, pushing buttons, opening apps just worked fine for that short period. And then the screen finally faded to black again. I could still use the power button and see the display powering on and off. But the screen itself was still black. Maybe my device has problems with running Nougats system UI...?
Any idea? :'(
Did you wipe the system partition before flashing?
Thanks for the response.
Yes, I did
One month has passed and the issue unfortunately still persists.
I have tried to flash an older Lineage version (v13.0 with MM) the other day and realized that even that one had troubles with my phone.
The UI was very slow and finally crashed to a black screen. In some cases only (pices of) the top bar were visible after the UI crashed. So basically the same as with the newer Nougat builds. I also noticed that at some point the screen toggled between full brightness and a yellow mode with lower brightness (reading mode?).
Could those issues be realted to the kernel?
In some rare cases I can get the newer builds to run for maybe 3 or 4 minutes until the UI finally crashes / the screen turns black. I can then push the power button and hear the wake up effect, but the screen remains black. The nougat builds were also running very slow in those few minutes whilst maxing out the temperature of the cpu.
Any further ideas?
Would be glad for any advice!
Edit:
Stock LP and MM with 21C and 30B still work perfectly, and even very smooth.
But as soon as I try to upgrade to another MM such as Mokee or Lineage 13 or the newer Nougat builds, the screen turns black when setting up the device.
It looks like only Stock-based ROMs (Nimax MM or Fulmics MM) appear to work at the moment!
Hello,
I am quite new to the community, did some flashing some time earlier on Xperia SP successfully but now I am struggling with Xperia Z1c (Amami) with new Pie releases.
I have been trying to flash my Z1C to Android 9, and all I can see is as those roms are working fine, but whatever I do, I end up with unusable phone.
When I tried clean flash (wipe Cache/Dalvik/System/data) and flash even the rom only (no gapps or any other module) I end up with a black screen after the splash screen is gone. When I flash also Gapps, I get the screen where I can pick the language and afterwards it says I shoudl wait a few moments and it literary goes forever, with 1 change that after 1-2 mins screen goes dark and from time to time it lights up with lockscreen or the screen to unlock SIM, but the touchscreen does not respond and also HW buttons are not working, shutting it down via vol up plus power.
I also tried to go dirty and use older oreo builds (Recovery Remix and AICP Roms) to go to Pie successors, but then I end up in a similar loop, where it says Android system is starting (this is when the touchscreen works) and then the screen goes dark and once it lights up, the touchscreen is not responding like in case of clean flash.
I am using TWRP 3.2.3 recovery plus AICP and RR roms. in both cases 8.1 roms work like a charm, but I am missing the security patches.
Is there anybody who could suggest if I am doing anything wrong, or just its my phone?
EDIT: happens the same on Lineage OS as well... quite desperate as I am not able to gather any info what could be going wrong
Thank you in advance.
