So I used LGUP tool to flash my phone and flashed with h811 v20r . The phone got hard bricked. Then I followed "Complete Unbrick Guide - 100% Working" this method but phone didn't boot up. Then I used QFLIP (this thread) method using ls991 files in QFLIP. My phone booted up after this and opened the installed android h811 v20r but it is not functioning fine. Camera , vpn and service disabled and if I try to change system sound settings or other, phone halts and also battery drains itself within an hour. This is the condition. I tried again flashing h811 different version (v20 v , v20 o , v20 r) but phone gets bricked and don't respond anything until I again use QFLIP to boot it again and it starts up and again shows the same condition as expalined above. Also there is a secure boot and error message when lg logo appears while starting phone

Hi, I'm fighting with a LS991 dead on downgrade. I'm able to connect it to qfil, but everytime I try to send the files, the result is the same: "Unable to send FireHouse NOP. Phone is not in firehouse mode !"
Any idea how to solve this problem? The phone get's into 9008 with the volume bottons, just in case it was wrong port I'd try with testpoint, but got the same result.

What was the actual Phone Model? Are You Sure is that LS991?
On This Situation who Bricked in his H811 all of them used LS991 File.

and Maximum got Successfully Boot up. Thats y i am not Confused About That File. You May Check Properly Your Phone Model or PCB Motherboard. and Try to use H811 Boot Repair File if that Accept!


But i am Not Responsible if anything Damaged!

I tried to flash my dead H815 with QFIL and I actually succeeded, at least it looks OK on the paper. QFIL detected my phone and flashed firmware correctly with no errors, but my phone is still dead. Any ideas?

After flashing to 10n, It works the same way as it was working in marshmallow. The zip file you mentioned is same as LS991 files. The phone behaves totally abnormal. There is an error comes in lg logo . "Secure Boot Error , 1006, staus: locked" . The phone boots up with ls991 files but T-mobile OS not working properly. Service disable, camera not working(doesn't even start). Phone halts. Battery drains. Imei etc (phone status) is unknown. I am not sure what is happening here . Please help me

Thanks for the info, I'll try with H811 and report result. Just in case tried with the SD card with image from a working phone to get download mode but it didn't work, and I'd try to change the firehose lite file for the DDR file, , and no way to wake it up yet. It's LS991, no doubt about it, but provably it was in a higher version than the one used to create the recovery files, the client updated 2 months ago OTA, and lost 3G, that's why he tried to downgrade it (it was in ZVG and flashed with ZVC) Wish me luck!

Same thing with H811, apparently the problem are the latest updates, that FireHouse files changed and are not aveilable. Provably I can solve it writing directly with some box for EMMC, I'll search on the city for someone with these tools (I'm the traditional "software only"guy, to avoid warranty issues for the clients, not use to solder PCB). Or I can try with SD card method with backup from same version to get download mode, but it looks that noone had been able to root that latest version yet to make the backup. Thanks for your help.

I tried reheating several times, no luck. Are you sure replacing only eMMC will help? How about CPU? I heard that it's also having such a problem. Where can I buy these ICs?

Hello Friend,

First Try to Change eMMC. I Don't Know About CPU!
If eMMC Changed Doesn't helped You Then Try Make Next Operation of CPU!
