Damn!
I also tried previous SD Card flashing methods, but It did not work.
When last_id.log file is created after the card is used to flash, it won't allow another flash attempt unless that LOG file is removed. Regardless, the device wouldn't flash with the full 6xx firmware previously in preboot which I think might be due to Updater.exe detecting fw/hw incompatibility of some kind. However if you get preboot back we can maybe try some other things.

Is there any solution for this situation?
Certainly running out of options and not having preboot shortens the chances very much further I'm sorry.

If you're desperate enough we can try to delete rgn14 which usually will force it to default into preboot mode. I'm not sure if that will happen with this damaged device but if you're prepared to try look behind the spoiler:

I'm sure you know the procedure and terms regarding risk by now. Good luck.
