Hello Everyone!
i will try to describe my problem in point by chronological order
- I broke display of my D802 with Cloudy G2 (KK) with possibly quickwindow option turned off (i do not remember), rooted and unlocked bootloader, and mounted a new one.
- Between broke and mounting new display elapsed 3 months, so i tried to reset Cloudy over system settings, for installing all apps and setting from begining.
- After that i had booloop, so i tried to go into TWRP, but every time i tried, logo of TWRP was showing for half of second and then screen was black (but backlight was working)
- After few times i tried to boot phone and it booted, but quickwindow clock shows up without possibility to unlock phone, so i tried to install cloudy g2 3.3 with quickwindow option off in aroma installer.
- After installation LG logo appered for quater of second and screen goes blank. In computer device was detected as QHSUSB_BULK, so i unbricked it without problem
- but after that there was need for install system over lg flash tool, so i installed original KitKat, but in "Firmware Update" screen there weren't red word Rooted. It seems to had locked bootloader and unrooted after QHSUSB_BULK repair.
- Then i booted clean original new KK, but there is also QuickWindow clock directly after booting system!
So for now i had:
- Kitkat
- Locked Bootloader
- Stock Recovery
- No root
- No usb debbuging (no adb)
- All time quickwindow clock
I tried to go into clock, weather, camera from down button and touch any soft button but there is no possibility to get into system and turn on usb debbuging for root, install recovery and install any CM based software to use phone like a charm.
I tried to unmount sim card, front and rear camera, proxmity sensor, take battery from inside to outside case f phone, antena wires and make a distance between mobo and case but no diffrence. Tried to use quickwindow case but it's not working....
AND FOR NOW when i am writing this problem screen turned on with noob system tips and system booted and i turnet on quick windows case! But it's not full solve.
Any ideas what may be a problem? I looked for photos and service manual of D802 and i know which one part on motherboard is magnetic sensor (becouse quickwindow working by magnet) but it's is not fired like other parts.
Sorry for not good English. I hope that you understand everything

Hello everyone!
My brother sent me is MX 030. It is the original Meizu MX HK version with the unlocked bootloader. Two weeks ago, he found his phone had crashed. The screen was black and he powering it off and then back on would not do anything (black screen - only vibrates on power on).
I got it today and first thing I did (after charging it-the charging mode works and displays a battery logo) was boot into recovery mode (or update mode on Meizu phones) and I was able to reach the menu. It let me mount the drive onto my PC. I downloaded the latest firmware and put it on the drive. I pressed upgrade and cleared data. The software seemed to install fine, but then the phone rebooted to a black screen - again.
Then I tried installing older versions which I found on the meizu website. They all install and I can see the recovery mode is different, but they all boot into black unresponsive mode (which drains the battery).
Having had other android devices before, I feel the phone is stuck in reboot loop.. I don't know what else to try or attempt. I feel am running out of options. The fact that the phone still responds to some commands and allows me to flash firmware should indicate that the phone isn't brain dead quite yet, right? Anyone else experienced a similar situation?
Thank you,
Oli
Hi,
I have a N4 that was new but the screen cracked on it and eventually the battery died as well (wouldent hold a charge). I got the battery and screen replaced but as soon as this happened I could not boot into any rom. I had twrp installed but everytime I tried to install a rom such as CM it would install but would stay stuck in the boot loader. I then used NRT to try and kick it out of bootloader and I tried several different stock firmwares, 5.01, 4.4.4, and 4.2. The only rom that was able to get past the boot animation was 4.2 it went to the welcome screen to choose a language but I could not select anything via touch screen. In that screen I could lower and raise the volume via the rockers and turn the screen on and off. I had twrp installed and the touchscreen worked fine in twrp. I also tried this: http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060 and it also let me get into the developer firmware but of course it is encrypted so I could do nothing. The phone has not had contact with water etc. Do I have any other options? Can I get some type of diagnostic such as logcat or something?
Thanks!
hi there
i bought an lg g2 d802 32gb , whene I checed its imei it said that it is a d800 model
in the first time the phone start crashing from itself , without doing or installing anything
then i update it to 5.0.2 when the screen start acting crazy ( whene i try to click a button the click goes somewhere else on the screen like whene i hit home button it open the menu etc ...)
than i thought its because of the update and i tried to go back to 4.4.2 , and that whene the phone wont boot to download mode and goes to qhsusb_bulk(qualcomm 9006) mode instead
, i tried to flash image files with the d802 images but they didnt work , than i tried the d800 file and oops it did work and i flashed 4.4.2 but the screen still crasy and a new problems came out
like sim is not readable and it consume battery life very quick (a full battery doesnt last a day in standbay ), and the size became 16gb instead of 32
I couldnt find any solution for my probleme , please help
no one knows a solution ?
I know that I may have to reflash partitions but I dont know how, but think that d802 partitions wont work , and d800 causes a lot of issues , any ideas ?
did you find a solution?
having the same problem for three weeks. After flashing a new rom the screen has gone crazy. Cannot use recovery mode because the screen has its own life....
Downloadin any KDZ file I have found using download mode doesnt help. The screen is still crazy.
Solution ??
First step, get an otg cable and connect your mouse. Second of you're rooted, then be ready to download a reboot app from the play store and reboot to TWRP.
From there backup everything and then reflash a rom.
See if that fixes your problem
Hi Guys,
I got my G2 back from my brother who have not using it for a while.
1st day it was working. I plan to install Lineage or custom ROM today...thats when the issue start:
1: it wont go to recovery mode. Even thou I have rooted and install latest TWRP it will only boot to Hardware control key screen, only this screen and wont boot to the OS it will be stuck on LG logo forever....
2: tried to go to Download mode....the same It will go to the same hardware control key only....
3: when I plug in to my PC it wont turn off, keep on restarting after I press the power button for a while.... only if no cable connected I can totally turn it off...
For a noob like me....looks like my G2 D802 is brick :crying: ...any suggestion?
PS: windows detect it( As below picture ), off at all when I plug in AC.....It Will just show the LG logo and the LED just flashing non stop until I pull out the cable and turn it off...
This is what shown on the laptop No Disk1/2/3/4/5 of sort showing on the Device Manager and on the phone each time I try to go recovery or download mode belowh happen:
https://flic.kr/p/QH2HzE
https://flic.kr/p/2bs67ne
Update 1: I found out why the phone was brick. Seems like my Brother ask his friend to install Lineage 15.1 on the it. After everything is verified ok. He wipe and try to flash the rom in TWRP but.....it failed and suddenly just freeze and turn off the screen. Maybe bad ROM download or some step miss....so now the Phone has NO OS and would not boot to anything only the Hardware Key Management....that's all....help? Need the phone as 2nd phone for company lines....dont wanna take the iPhone 6 from my boss....
help?
Hi guys,
hopefully you can help me or link me to a thread with some help.
After 5 years my g2 broke down last week. I had the official Android 4.4.2 and have never flashed anything. Don't know if it has anything to do with it but i didn't have any free storage left of my 16gb (european version, so i gueass D802). The days and weeks before it warned me that i used all the storage and some apps won't work properly ( I didn't care because I ran without problems for month)
My phone broke down and now I am stuck in the boot loop. When I disconnect the battery on the back and then connect it again and plug it in my laptop the LG Logo will appear and the phone will charge. No Problem there, I still have battery left. When I try to turn it on the LG Logo will appear and then the display turns black, you know how this goes.
I can not enter the recovery mode nor the download mode. My Laptop wont recognize my phone on the device manager or somewhere else. What my laptop does, is that the typical windows sound comes when I plug the G2 in and then after some seconds the sound comes again when the phone turns black.
Then I got a error message:
Kernel Crash! DemiGod Crash Handler : Kernel Crash!
From there I did not reboot successfully. How can I get a Kernel Crash with the normal Android Software? weird.
All I care about are my pictures left on the phone. I was dumb enough to not make a backup. Do you know a way to save my pictures? Can I somehow exchange the storage chip?
Please help me.
