[LG G7 ThinQ  Questions & Answers] MagicOJB:
Hi!

Long story - short:

- I played around with a custom rom, but due to Google Pay issues I went back to stock rom, but forgot to flash the stock bootloader before I locked the bootloader and also didn't activate the developer options to unlock the bootloader again. So now the system does not allow me to boot and I'm stuck.

- Tried LGUP, LG Bridge, LGMobile Support Tool which all work but are not able to repair the locked bootloader problem.

- I don't care for any data on the phone - I just want to get it working again

- No warranty (as anybody can see from the log below) due to having unlocked the bootloader at least once

On every boot it shows: "Your device has failed a routine safety check and will not boot. This may be a temporary problem. If this message occurs repeatedly, visit this link on another device and refer to the Red case: g.co/ABH"

Currently both bootloaders are not bootable (output from fastboot getvar all):

(bootloader) eio_count:0

(bootloader) dm_count:0

(bootloader) lock_count:1

(bootloader) unlock_count:1

(bootloader) unlocked:no

I can see that I am not the only one which fell into this trap but from the existing threads I can't see a clear strategy to solve this. So help would not only serve my cause...

I would guess (wild speculation due to lack of knowledge) there are two options for me:

1) Flash a kdz file with dev options to unlock bootloader pre-set (but I don't have such a thing) to be able to unlock the bootloader

- Is this really possible or do I have an error in my thinking about this? If not, does anyone have such a "recovery" image for LG G7?

2) Force the flash of the stock bootloader (I have a extracted bootloader boot_a_65286.bin from my stock kdz) with Qualcomm tools (QPST, QFil, 9008 mode???), but I don't know how

- Do I understand this correctly that I do have to shorten two pins on the motherboard to get into this programming mode or can I also use this from EDL without opening the phone?

- I guess, independent from the former question, I am in need of "outside" assistance for this solution because of some non-public files needed for this procedure

Are there other ways to fix this? Your help would be greatly appreciated!

Best regards,

Oliver
