D802 "not" booting up - G2 Q&A, Help & Troubleshooting

Hello Forum,
first of all, I used Google to find out what to do with my problem, but found nothing. (Just for those, wo wanna tell me how to use the serch )
So, I am german... my english is not perfect but hopfully you will understand it.
My Phone:
LG D802, rooted, with latest TWRP installed
My Problem:
I can flash any CM based ROM but if I try to flash CloudyG2 , MIUI or Flyme it just get suck at booting.
I press the powerbutton, the screen turns on, the LG logo appears and a second later it just turns black.
After a while I figured out, that the phone boots into a "Fastboot mode without lines showing on the display" - And if got a QHSUSB__BULK which i cant fix with SRK tool because it´s simply not detecting my phone.
The funny thing is, I can still enter recovery to flash back my CM 12 - and its fully working - but I dont want that.
Flashing .kdz with LG Flash Tool 2014 isnt working too.
It only shows up the "normal" error message and if I would like to retry. And yes I waited for like 20 minutes at that state and still nothing happens.
Hopefully someone out there who can help me
Greets,
Ims

I think you have the wrong bootloader...
Flash the right one (or the patch from the d802 thread), reboot recovery (not system) and try again.

Phone screen black, fastboot loads ok.

Hi guys,
I recently tried to flash a rom on my phone and when the process was done, all I got was a black screen.
Fastboot still works and I can flash euro roms like on the tutorias fine but the phone simply wont boot.
I can go into emergency mode to flash in it in KDZ, the flashing works fine but still, the phone only displays a black screen.
When I press the power button it vibrates, the PC recognizes the device fine, so I know the phone isnt bricked, I just cant get it to display anything on the screen! please help!
Which rom did you try ?
Using swiftdroid RC4 2.0, but I found out what the problem was. Since on flashboot factory reset was in German, "reset und wipe" or something like that, I did not check it. Reflashed it and it is now working, the only problem is taht tehre are no boot animations whatsoever. only a black screen between pressing the button and going into android. any fix for that?
thank you for the replies!
EDIT: Also, by going into reboot > Recovery, nothing is displayed. this only happens on boot. I flashed originally with Euro+fast.kdz, and that is when this problem begun.
Flash this boot.img
and for the recovery, ace you installed??
I installed CWM for recovery, if that is what you asked.
Going to try to flash it and let you know, hope it does break anything
EDIT: nothing. No boot images. Going to leave it alone until I need it for something. I use an X10 mini, I just bought this phone for testing. Not liking the resistive screen!
you tried to flash an X10 with Rc4 ?
No, I have an X10 which is my default phone, I boght this optimus for testing, I flashed RC4 on the optimus, not the mini. not that stupid
You're not the only one with this problem, this will fix it.

Stuck at Android Animation -.-

Greetings all !
Since i am new here, i have a great problem.
So, my phone stopped working few days ago, i needed to log in to my account or something, didnt knew i can fix that with "hard reset" so i googled about 3 hours till i found this forum, great work me !
So i looked a lil bit whats going on here, was searching and searching till i found out how to flash a phone, so i did, and had no success, almost bricked my phone :silly:
So i keepd searching this forum till i found this "

so i downloaded that "setup" file, installed it, worked great, i was amazed to be honest, but to be honest, this is the worst mod ever made for android. cynamogen mod cyna my ass -.-
So here is the problem, i didnt like that 2.3.7 update at all, and that addon cyna thing, so i waned to roll it back, connected my phone to PC, removed SIM, Mem card, found a workin ROM i installed before (before i found cyna and android 2.3.7), used KDZ, selected all the options required, and started an update using KDZ, after it finished my phone restarts it by it self, and god stuck on "ANDROID" animation, i thought its bootin' so i let it about 20-30 min to do so, nothing happens :/
UPDATE:
Now my phone is stuck on the LG LOGO, i cant do any thing, all i can do is go in DL MODE but its useless, my pc wont recognize it, so does KDZ, nothin is recognizing my phone, any solutions ?
So my question here is:
- How do i install 1.6 or 2.1 OFFICIAL version (can be CUSTOM ROM) i dont care, i just want my phone to work again
- What is needed (apps, kdz files, etc)
- Is this so bad, did i bricked my phone or ?
btw. Here are some infos 'bout meh:
- Location: Bosnia and Herzegovina
- City: Sarajevo
- Provider: BH TELECOM
- Phone: LG GT540 Optimus
if u need more info just ask !
I DO NOT recommend to use kdz.
if you don't like cyanogenmod, you can try
1. aosp 2.3.7
2. some modded 2.1 ROM
3. stock 2.1 from LG
they can be flashed via recovery (clockworkmod)
as you now already used kdz again i'd recommend to try the following: turn off your device and try to reboot into recovery:
press and hold HOME and then press POWER.
hold HOME till CWM boots up.
if this doesn' work you may try fastboot:
press and hold CAMERA, press power and hold CAMERA till you see a black screen, PC should recognize a new device (fastboot interface)
if this doesn't work too try too boot and hold these buttons:

[Q] Hard bricked G2 after flash

Hi everyone
I may have bricked my G2. I use to have a Samsung Galaxy S which I flashed many times so I kinda know when I mess up with instructions. This time though, things look a bit more serious... Anyway, here is what happened:
I flashed the Cloudy G3 rom (1.0) for my G2 D802 32gb. Original rom was stock rooted 4.4.
I followed the instructions :
- Backup rom
- All wipes
- Flash kitkat baseband
- Flash rom zip
- Get through the aroma installer steps
But then, when it asked to reboot, the phone just shut down.
Now it won't turn on. All I have is a quick look at the LG boot logo, and then the screen goes all black (blacklit is still on) again.
All I managed to do so far is maintaining the LG boot logo a bit longer on screen by alternatively pressing volume + or - at random times.
I can't access recovery or download mode anymore.
Plugging the phone will only show the LG boot logo and do all the same.
The phone is no longer recognized by my computer.
When I plug it, I get 13 new windows asking me to format the device and one I can explore.
Inside, there is one folder named "Image", filled with 51,4 Mb of files...
Quite confusing.
I don't know what to do, so any help to get the phone back to work will be appreciated
Thank you in advance.

At least I'm not alone :laugh:
I found this thread but haven't tried yet. Don't know if the problem is similar.
I really hope the phone isn't dead, it's almost brand new
This is exactly what I have . The main problem is we can not see phone partitions. Always the alarm "can not access " or "format" !Waiting for some body to help restaure our LG G2.

Are you still under warranty. If you can't get into download mode that means that LG won't be able to either. You could process a return directly from LG.
Problem solved ...
Somehow I did manage to hard reset (vol - & power, wait for LG logo, release and then press vol - & power again) and then access recovery mode, so I did restore my backup (which had been renamed to ... 1970-05-01 ! lol) and my G2 is now back to life.
Weirdest thing ever... Kinda worried about flashing it again now !
Thing to remember : always have a backup file.
You are lucky man! I've done it but nothing after. I can access to hard reset but when I push power button the screen goes black as before ....
Is it actually in "Download Mode"?

So, if my G2 shows "Download Mode" on the screen with the little white dots, but it's not recognized by Windows 7, Ubuntu, or Knoppix, and is for all intents and purposes, non-responsive, does anyone know if it's actually in "Download Mode"?

LG G2 Might be bricked, not sure.

Hello, cutting to the chase
Model: LG G2 D802
Story time: I tried to install ressurection remix rom through the sideload, after fully wiping my phone ( Wiped system, data, yada yada ) it showed some kind of an error about SU not installing properly, I thought well if I'll reboot TWRP will automaticly install SU for me, so when I tried to reboot it showed that No OS is installed, I thought it's a simple bug so I'll reboot to recovery again to check and bam. Nothing works.
+ Can't boot into recovery ( Tried volume down + power button ) LG Logo shows up and goes blank again ( Note that the screen doesn't turn off, just stays black, after holding it for a couple of seconds I can see screen going off completely but can't turn it on)
+ Can't turn it on normally.
+ Can't boot into download mode.
+After plugging it into an USB it mounts a D lettered drive with 63MB stuff in a folder called image with *.mdt files, modem files( I can screen it if it's important )
I'm clueless, never happened to me even though I flashed a lot of roms, I think I bricked it. Help?
UPDATE: I managed to quickly release Volume Down And Power buttons when LG appeared for half a second and hold it again, succesfully booted into TWRP. I haven't bricked it I think. Will tell how it goes <3
Hey man, how'd it go?
I'm in exactly the same situation as yours, can boot into twrp but nothing else works, i fear of the qhsusb_bulk brick but these people don't even seem to have recovery.
Any suggestions? Go back to stock? How?

How did it go!? I'm in a similar situation (but can boot into download-mode). Would love to get back to twrp, since I want to give it a try to flash another cm (stable). Thanks for sharing your experience...
If its picking up bulk mode normally its hard bricked there is a guide for restore nearly all g2s from hard brick having done it myself included 1st time took me a week to get back up but. Now i prob take about 45 min just cause i aint had one in a while

Hey there, can you specify what you did exactly or where to find!? Do you mean something like this? (can't post outside links, in XDA-forum, title is "LG G2 is UNBRICKABLE NOW! [FIX REAL HARD BRICK]") Thanks for help...
Yes thats it. Lol i still got the files on my pc for my g2 i keep the whe setup cause im on the g3 now i just check in the g2 forums cause i had mine for 2 years and modded the crap outa it but yea i keep all the files on hand so if anything ever happens i can fix it almost on the fly now
Well so what happened to me that I managed to get inside the TWRP. When it lighed it up for a second I quickly released and held again that got me inside magically. So then I just transfered new rom and tried to install again. Sadly I didin't see that the ROM Im trying to install requires bump TWRP and I bricked my phone again. Though I entered download mode and flashed the stock rom through LG G2 flasher.
heres a video i made, how to go into recovery. for those that cant get in to twrp.

No Recovery Mode after upgrade CM 13

Hi guys, I have a problem with my LG G2 16gb. Today I have upgraded CM 13 with the last nightly. After having flashed Rom and Gapps I rebooted the system. The system runs but with some bugs (dialer crashes, screen doesn't wake up anymore when it goes in standby mode). So I decided to come back to the previous nightly, but I suddenly appreciated that I can't go in recovery mode.
I can go in download mode but both Flashtool and SRKtool don't work. I really don't know how to do.
I admit that I'm not able to resolve 2% problem with the fix.
I read that if I try to flash a firmware 10A then Flashtool should work, but I didn't manage to find a mirror of it.
Someone could help me? I Would be grateful
Same problem here. Flashed from cm-13.0-20160427 to cm-13.0-20160430 and now have the same problems. Using d802 with twrp-3.0.2-0
CM is booting, but has the same bugs as written above - no dialer, once in standby screen doesnt wake up any more.
I tried to reboot in Recovery from booted CM, the Phone is hanging with the "Reboot" on Screen. Same with normal reboot or shutdown. It just hangs. The Combination with the Volume Key Down & Power wont let me in Recovery as usual.
CM13 ist really awesome and nightly to nightly it was getting better, but the nightly today just went that wrong.
Would be nice if there is some solution to get the phone back working.
Thanks a lot for any advice or help!!!
Greetings,
Feldinos

I had some problems with booting into recovery as wel. CM13's latest nightly kept freezing my phone and I wanted to go back to my previous backup, but I couldn't boot into recovery from anywhere. Luckily I remembered that the button combination has changed with the latest bootstack I installed. It'sn now like this:
Force a shutdown by holding the power button. As soon as it goes black, press power + vol down, release as soon as the logo appears and then hold vol down + vol up. Then you should be able to get into recovery.

Thanks a lot for that information! Almost forgotten that i had installed an new boostack as i flashed the first CM13 nightly that was released.
I was now able to get in recovery and flash 04-27 nightly. Now my phone works normal like it does before i flashed 04-30.

When it reaches 2%, it suddenly appears a message telling me that my g2 is disconnected.
Unfortunately for modding, I installed w10. My pc has gotten better, but almost all the programs for modding don't work anymore. In addition to this, I didn't found drivers working well.
I'm thinking about restore w8.1.
There's a way to fix the problem of 2%, but I am not so prepared to use adb.. I'm aware about my limits

You're welcome As long as you can remember the different button combinations to get into recovery, you shouldn't be afraid to flash roms. Just never forget to make a nandroid backup before upgrading any rom!
If you start to flash roms, you WILL mess up at least once And this time, it wasn't actually your fault, CM13 messed up.
