Bricked D802 Stuck in fast boot after flashing Kernel - G2 Q&A, Help & Troubleshooting

Bricked D802 please help (stuck in fastboot)
Hi to all community,
So here I am on my vacation and on the very first day I have bricked my phone.
This is what I have done:
1. Installed TeamBliss 3.9 ROM - worked fine
2. Went to the Menu/Settigns and downloaded Kernel and flashed it in TWRP recovery
after that I am stuck in fastboot, kind of...
when I power on the phone I get message
[800] Fastboot mode started
[850] udc_start()
and it goes nowhere from there...
I can get into recovery if I do a hard reset combo...
And there if I want to do anything (like factory reset) i am getting message:
Factory Reset Complete
FAILED
e: unable to mount data
e: unable to mount storage
and on the "mount" menu I can't click on the data, and it shows internal storage 0MB
I can get into download mode when the phone is off and i plugged it in into computer and press VOL+ and it goes to firmware update, but I am not able to update (or flash )anything.
I have installed LG Drivers, SDK, and universal adb drivers.
My phone also isn't recognized by computer (it is on the device manager but I can't see it like a storage to drag and drop something into)
Can you please help me, because i am loosing my mind...
Will buy you a beer definitely.
Thank you all for your help

LG G2 all data wiped

Hi,
I'll did a factory reset with TWRP via advanced,by accident all partitions,including the internal storage partition.
Now my phone does nothing, but i''m able to boot in to TWRP.
When i'm connecting my phone to my computer i'll see a error with the driver. I'll installed the LG drivers from the website. But still see a error with the driver.
Error message: There is no compatible driver installed for this device.
I'll need to push a ROM to the phone, anyone a idea ?
Thnx in advance.
Device: LG G2 D802 International
From twrp you can mount usb storage (your sdcard or internal memory)

If you have a USB OTG cable, load ROM/gapps/etc onto a thumb drive and connect to your device. In TWRP, go to mount and select USB. Go back to main menu and select install. Scroll for USB and select files.
I'll solved the problem. I'll reinstalled the drivers, restarted my computer and the supporttool regonized my Phone again. I flashed the stock rom via downloadmode.
Thnx for your answer.

D800 broken download mode

I once bricked my phone by installing a L01F ROM on my phone by accident, and had to manually reflash every partition in windows CMD prompt. I have been using my phone fine since I recovered from the brick but I was going to tot to stock and update to lollipop but my download mode says secure boot error and shows up as qhsusb_bulk in device manager and gives me a ton of partitions. I have been looking around for a solution but cannot find one. The only thing that is broke is my download mode. I have recovery and a booting ROM.

i have bricked my phone badly.., i tried to install the ota update for P10 Plus (VKY-L29C432B123) with FlashFire and in the middle of the update the phone went black and my problems began getting worse.
i rebooted the phone and got into Error mode Func No: 11 (recovery image) and Error No: 2 (boot faild in recoveryboot mode!).
so i followed a guide and reinstalled twrp to attemp to restore the system somehow, so i kept following the guide and i went into twrp --> wipe --> format data and here my real problems began..
i did many attemps to install any firmware both stock and roms but i got into system mount problem and i can't do anything to transfer files to system i have tried adb but it can't find my device, tried adb sideloaded doesn't work eaither.

To boot into bootloader mode you have to plug the usb and hold volume down while booting.

That's a big problem if you can't access fastboot or erecovery.
Seems you messed up the 2 recoveries.

yes it looks like.. i mean, it wouldn't be a problem to flash recovery again, but i can't get the device to boot into the bootoader so i can work with fastboot..

You format data on twrp after install twrp?
You could try to restart to recovery via TWRP and be sure to unplug usb-c cable prior of doing that then try flashing something.
If that's not working you can try the Format data button in the Wipe/Advanced wipe section, afterwards wipe everything, connect the phone to the PC (while in TWRP) and transfer ROM, GApps... via adb push. Try flashing the ROM again, if it's not working again remove the cable and restart recovery - flash again.
I encountered this kind of problem and these techniques seemed to solve it.
it's work thanks!

Thanks so much, man. you guys in this forum rock!
hey to everyone who faced problem like that wont solve with this solutions like wipe data or boot recovery and some type of this things, sometimes the problem isnt that serious and only requires like force restart with volume down+power button and then turn your device power on again and maybe it should work like it did for me (sorry for bad english )
thanks

Flash stock rom via fastboot.
And try to reboot to bootloader from twrp it'll put you in fastboot mode.

That's what I told the person to do in short he/she didn't respond.
He/she should update the thread whether he/she got it working by doing something or fixed it via service center. Others just try to help without knowing if it is needed or not.
First of all, i want to say i'm sorry to all of you.. especially for those who tried to help me by replying my thread. I'm sorry for being silent and not updating on you guys. I managed to figure it out the next day after i posted this thread before any of you replied and just kinda forget this thread- which is a bad thing to do. I'm sorry guys. I won't do that ever again.
With that out of the way, i'm going to answer all of your replies

I tried that, it didn't work. Either reboot to system or bootloader, it just went back to TWRP.. with the "Keep System Read Only?" thing.. acting like i just installed TWRP for the first time. Even when i chose to turn off the device, it came back to TWRP.

Again, sorry for that
Here's what i did to fix the issue :
1. After some more searching in the next morning (literally the next morning, few minutes before i gone to school), i stumbled to this thread post : https://forum.xda-developers.com/showthread.php?t=2522426
it says that if you "Put the phone under a strong light and longpress power and volume down, your phone will reboot in bootloader.".
So i tried that. I hold my phone right in front of my monitor, then hold the power and volume up to get into fastboot mode. And Voila, it worked. I get into fastboot without any problem whatsoever.
Somebody else also replied "Just hold the power and volume down for a long time and hold it in front of a bright light, something about the proximity sensor."
So.. yeah. Didn't really know how it worked out, but it worked. :silly:
2. After that, i just installed a different version of TWRP (This one specifically https://dl.wafuu.id/twrp/X00T/twrp-3.2.3-0-X00T-20181214.img which i got from someone in the telegram group) and just redo the HavocOS installing process. It went smooth, and i manage to boot the system without any problem.
Problem solved. Just like that. However, i think i know what was causing the issue.
When i was trying to install the GApps (before stuck in bootloop), i only managed to get to the part when i had to choose to either save my choices or not. After that it just went back to TWRP. I didn't know that it wasn't actually installed yet, because i thought it was installed already. Yep, that was my first time installing GApps and i actually never seen the entire installing process. The way i know that is when i installed it after the fix (after i installed a different TWRP) and then saw the "installing things" part. Silly me.
So i think that was the issue. It was because i used an older version of TWRP which i got from this thread https://forum.xda-developers.com/asus-zenfone-max-pro-m1/development/recovery-twrp-3-2-1-x-t3787134 . Maybe GApps didn't support that version. I knew it was an old version of TWRP. Why i was using that version and not the latest one? Because when i tried to install the latest one from this thread https://forum.xda-developers.com/as...ent/recovery-unofficial-twrp-3-2-3-0-t3888110 , it didn't work on my phone. It fails to detect my internal memory (0mb).
I think that's all i can say. Again, i'm sorry to all you guys for the late respond. Thank you for replying my thread and trying to help me. I hope this thread will eventually help someone who faced a similar problem to mine.
*Last but not least, Shout out to Dyruz from the telegram group who provided me the working TWRP and tried to help me as best as he can. I would've not fix the issue this because of him. Cheers!
