bodhi, Sorry for the new topic creating. I've just started again the unbricking. Yes, it doesnt came out anything on the console no matter what converter am I using. Also all the two converters are brand new. Also I measured the CMOS battery only a few millivolt missing. Battery original 3.00v, measured 2.98v. I used this picture as a basis for wiring.

I downloaded the kwboot file. But i cant run it. I added execute permission to the file and i tried to run it with ./kwboot the file was in the current directory and the linux says pi@raspberrypi:~/tools$ ./kwboot -bash: ./kwboot: No such file or directory How can i try out the serial port?by Krisztian12005 - Debian
It still doesnt work sadly. I used that command kwboot -t -B 115200 /dev/ttyAMA0 -b uboot.2017.07-tld-1.nsa310s.mtd0.kwb -p and still says Sending boot message. Please reboot the target... Firstly i powered on with the power button then i sent the command after that i powered off with disconnect from the psu and then reconnected it then i pressed power button.by Krisztian12005 - Debian
