Found a solution: just install the kdz with lgflashtool.
NB: don't press ok to any error message 'cause the process works!

What bender mentions we are about to do that with my boss, you have to "shortcut"(?) the board on 2 specific points. Sure you have to open up and dissasembly the back of your phone. I try to keep inform

You've hardbricked your phone, because you can't enter dl or recovery.

My PC is not recognizing phone at all so the process won't even start. That is maybe because the battery is empty. I will try that after I charge the battery with my colleague's phone but I think that is impossible.

The same here, when powering the mobile on it shows
Boot verification Failed
-cause MISMATCH_SIG_LEN
I don't have a custom recovery. The only screen I could see is the default mobile recovery which only offers erasing data, any suggestions.

Not at all, just open it, shortwire the 2 pins, use boarddiag to flash proper partitions and in the end when download mode is fixed just use lg flash tool or lg flash tool 2014 to flash your kdz(or tot)

[Q] bricked my phone

hi...guysss.......i bricked my phone how can i put zip file in sd card......no system in my phone or sdcard also been empty
Make sure all power is off, then hold both up and down volume and connect a USB cable then restore from kdz. Your phone is just soft bricked.

Phone stopped working for no reason - can only get as far as the bootloader now

Tried looking through threads and have spent all day trying to fix it.
Phone was working fine a couple days ago until it ran out of battery. Since then nothing.
If I try to turn on normally I get stuck on the Google screen. Only other thing I can do is boot into fastboot/bootloader but from there, if I try Recovery mode it sticks in a bootloop
I think you have a hardbrick bootloop, There is fortunately a kernel and recovery developed by developers to overcome this problem, but you'll need a unlocked bootloader as it involves flashing recovery and boot.img. If you have boot loader unlocked, go to general section where you'll find a thread regarding the same. All the best
I tried that - flashed the recovery but when I try to launch recovery mode I just get a bootloop again.

If you can unlock the bootloader again, I'd guess the flash didn't manage to erase everything.
Normally you'd have to boot and enable OEM unlocking before being able to unlock bootloader.

Did gsi android 10 flash recently?
if the answer is yes
with the bootloader unlocked you must boot twrp and flash stock-repartition.zip
You can now block the bootloader in stock without bootloop

There is another way too. Put your phone in EDL mode (fastboot oem edl) and flash the stock rom again. Even with clear_all_lock option enabled ,your phone won't lock your bootloader. When the phone boots up after flash,and you see the boot screen wait until you see erasing circle,after the second reboot,hold VOL - and power button until you go in fastboot mode. Then on your PC type: fastboot oem lock. The phone will boot up,then it will erase user data ,and you are ready with locked bootloader. I didn't have the stock repartition script ,so that's what i did.

If it works unlocked but not locked, something is modified. Leave it unlocked or flash a complete stock rom.

Probably something failed to flash. I don't know how much error checking the script has. Try again? Take note of the output, looking for warnings and errors.

How did you root your phone? Rooting the phone is as simple as flashing patched init_boot.img via fastboot flash init_boot. A lot of users here brick their phones because they patched and flashed the boot.img instead of the init_boot.img.

If you can enter fastboot you can still fix..flash your original boot.img from fastboot.

He used miflash, QFIL (with various different parameters than normal use), QFL, and fastboot. Finally he recreated two super partitions for my phone and flash odm, system, and vendor images into the supper partitions. After 4 hr of trying, my phone boots however I still have the red warning "Your phone is corrupt".
