STUCK at LG Logo, NO Download mode..Please HELP!!

hi all,
I have posted my G2 problem in another thread but was hoping more people can see it and help me...
PHONE Stuck at LG Logo after power up.
NO Download Mode,
here goes..
Believed I was conned... and this could be what happened to my LG G2 'D802':
my mobile is actually a D801 phone (motherboard) NOT D802 but loaded with D802 ROM
Phone was flashed (by me) with D802 ROM to remove error "Unfortunately, the process com.android.systemui has stopped" caused by corrupted Build.Prop system file during some editing.
touch screen error after new ROM was flashed (tried many diff roms), likely due to incompatible phone settings.
unable to flash D801 kdz since the phone was configured to 'D802', incorrect model detected while trying to flash.
managed to get a D801 TOT file that can resolved the incompatible model issue
Flash completed, phone rebooted..STUCKED at LG LOGO!
pressed Vol+ and USB cable, cannot enter download mode...stucked..
Factory reset using hardware keys, same problem..
please help ! any suggestion/s would be greatly appreciated!! thank you!!

use flashtool with another *dll

His download mode is not functional.
When in factory reset - connect to pc(does it throw errors or add a new device?)
If yes..then - read this
If no then still read it.

After Hard reset, phone continue stuck at LG LOGO.. PC detected mobile as "LGE AndroidNet USB Serial Port (COM41)", see attached.

But you did in one of your screenshot ...
Anyway, when you let the phone continue to boot, what happend? lot of force close?

Just plug your cable to usb. Turn off phone and inmediately hold the button up and ull be in download mode.
Or If U have 801 rom try to root your phone and do recovery as 801 phone, after flash 802 rom !

Wait so what can you do? Hard reset? Download mode? Nothing?
Can you plug your phone and check that your phone is not detected in device manager?
All the drivers are installed?

Same issue
I am having the same exact issue as TEDET123. !!! installed ubunto in one of my PC, tried the same procedure as explain at

the ubuntu doesn't show any SDB !! need help!!! went to the famous lg software guy in my town. He said MMC chip needs to be replaced ! I knw he doesn;'t have its solution and trying to demotivate me thats it! I knw there must be a solution to this issue!

I would try to force the phone into qhsusb mode then flash only laf.img,aboot.img and boot.img

LG G2 D802 hard brick [HELP]

Hello. I'm new here and recently I had bricked lg g2 but I used this tutorial https://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404
Everything went fine and after flashing partitions on linux and it booted to TWRP but there was again white error Security something and I had to flash partitions again. And thats where it begins.
I accidently did something wrong and now I can't power on my lg g2. Cant recovery, download mode etc. When plugged to PC it only shows in device manager QHSUSB_BULK but none of partitions are visible.
Is there anything I can do more?

[Q] Any advice for bricked G2 [D802] make unbrick ?

Hi everyone, i have a G2(D802) which i have used for 5 years. Yesterday, when i turn off the screen then try to turn on it didn't. I tried to reset with holding power button like 20-25 seconds. It stucked at LG logo. After many reset nothing happened. Then this morning i could was able to open my phone, so i thought it was a problem about software things, so i backuped everything and change my rom(i was using Lineage 14.1 ) to Resurrection Remix. But same thing happened, when i turn off the screen it has gone again. So i decided to install stock rom back. But this time when i used Flash Tool 2014 and appropriate KDZ, it stacked at 4%, after trying different cables, ports,windows 7/xp and programs (like LG Mobile Support Tool, LG Up) in Device Manager it seemed as : "qualcomm hs-usb qdloader 9006" and no recovery mode no download mode, when i google this problem i found it named with "qhsusb_bulk" and i found this article and successfully recover download mode. Now in Device Manager it seems as "LGE AndroidNet USB Serial Port".
TLDR: I can only open download mode, no recovery, it stacked LG logo, when i use Flash Tool 2014 or LG Mobile Support Tool with different KDZ/TOT it stacked at 4%. What should i do? What's wrong with my phone? I need your help urgently because i have no other phone. Thank you for reading.

hi there.. unfortunately LG did a mess in my opinion! After buying G2 and G Pad I will never buy LG again because of this..
anyway, assuming you're doing everything as described into the guides (like port COM 41, copy the right DLL file etc) there is one thing I would try in your situation: trying with a different PC, in particular a Windows 7 / XP one..
also I read that sometimes this issues was randomly gone after trying and trying and trying and trying and trying..! If available I would also try different KDZ firmware (but be sure it's for your model.. as long as it is it doesn't matter if it's JB, KK or LP)

Thank you for your suggestion, after several hundred attempts i successfully go back to stock rom(an Indian stock rom which i found it in storagecow link), but the problem is; when i turn off the screen, i can not open again, and it restarts and stuck at lg logo. After hundred times reset, phone started normally, then i flash a twrp recovery (with autorec) and go recovery. This time twrp said Unable to Mount System,Storage etc. so twrp shows internal storage: 0mb and all folders(data,sdcard,system etc.) empty. I mean define this problem is very hard and i think it is very rare problem. I'm not sure which part of the phone is the problem. I don't know is this a hardware problem or a software(like wrong partition or something like that) problem.

so ROM is flashed but no files are anywhere? Did the same happens when you browse the device with the windows command Prompt / Linux Terminal?
Yea anyway weird, maybe you can see if this tool has original partitions for your model: https://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076 - please pay attention if you do it and backup the partitions you have atm before

I used this tool when my phone showed in Device Manager as : "qualcomm hs-usb qdloader 9006" and it worked, today when i opened my phone(after install stock rom again) i kept the screen always open. After 5 minutes, suddenly screen gone and stuck at lg logo. Now I think that the problem is definitely hardware. Because i did nothing and phone was connected with a cable to my pc. If the solution is to change a part(like the processor) inside the phone, I will write here what the problem part is. Thank you again.

I found the problem part. It's the eMMC chip. I disassemblied the phone and heat the relevant chip (on my motherboard the chip named as Toshiba) with hot air gun. My phone worked properly for 1 minute, then gone again.

you know what: I think my device has the same issue, eMMC is damaged.. I'm not using the G2 as primary or secondary device anymore but from time to time I like to flash something and using it.. but it's almost one year that when stuff I have no error but when I boot the device and start using it I have random reboots.. but they are totally random and almost happen when installing one app, using a system app or something like that. it happens with both stock firmware both with custom ROMs.. basically I have to flash and using the device for a day and if I have less then two reboots in that period I go on..
I'm not an expert about hardware matters, do you mind linking me a video on YouTube about what have you done with the airgun? Also I tried to search for spare eMMC but I wasn't able to find any (some time ago) so the option would be to change the motherboard.. did you find something instead?

This is the video I get help with: https://www.youtube.com/watch?v=ft8V5yrQFic
this guy did this for g3 but doing for g2 also works. This is definitely a temporary solution. It works maybe just 1 minute (like me) or 1 hour if you are lucky maybe 1 month. Changing motherboard is primary solution but it is expensive and worthless. I think that is chronic problem for LG G series. There is no proper heat dissipation on the motherboard. They have just put thin metal plates. Maybe you can try after the heating process, just put a thermal pads the relevant chipsets. You can see from this video: https://www.youtube.com/watch?v=HMdvG6w7etU

But basically you are saying that this issue related to the eMMC is not because the chip is damaged but only for the temperature it reaches?

Yes, because of the eMMC chip is damaged. But the crux of the problem is processor heats and cause of no proper heat dissipation this damages other chipsets. Thermal pad solution must be done after chip replacement.
