[SOLVED]![H870]Device keeps going into download mode after interupted Uppercut flash

[Norbert Magyarics]

Hello there.

I unlocked the BL yesterday and flashed TWRP and then AEX latest Oreo based ROM. It was fine, but since I came from Oreo, I did not have fingerprint sensor working.
So I wanted to go back to Nougat and then flash the AEX from there. Uppercut didn't recognize the phone so I installed a stock based rooted Oreo from TWRP.

I started the Uppercut flash with a stock Nougat system, but it was interrupted (in upgrade mode, refurbish mode doesn't work at all) referring to: error 0x2bc invalid command response code.
Later with another kdz file it gave me: error 0x2bc crc checksum error

From then on I cannot get into anything else, just download mode (in there, wildly short-pressing the Vol- and Power buttons gets me into a menu where I can turn the phone off, and I can boot into Fastboot mode. )

In fastboot mode I flash twrp and then when I try to boot into twrp by selecting the usual reset system options, it just gets into download mode again.

I could not get any kdz to install on it so far. I tried H87020C, 10D, 20A.

So now I have download mode, which fails and fastboot mode, in which I don't really know what can I do.

LG Bridge doesn't help, LG Flash Tool stops at extracting all the kdz files I gave it and LG UP also doesn't work.
The bootloader is still unlocked.

Please help me with this.

All of a sudden, for the fifth sad trial, LG Bridge somehow managed to flash a Nougat system onto it.
