Also i uploaded image for a second time on first Pc (amd/nvidia) through lan-cable and was no problem at all.
Tftpd32 ready to upload, router - power off, power on then quick pressed the 30/30/30-button till the "sevice-led" blinked fast and autoupload...
Tryed through jtag-cables and ttl-usb - no responses.
Maibe another time will play again with this.
BEST: use lan-cable (udp) and no other soldering stuff !
if the TFTP method worked it must have been v.1.8 or higher, since v.1.0 does not support this recovery feature... (read on another forum: TFTP recovery wasn’t part of the Uboot (without needing serial) until v1.8 )
I'm trying to debrick v.1.0, which was running DD-WRT but bricked after trying to update to newer version, TFTP method is not working, tried with Wireshark to scan, there's no ARP request to pull firmware from any IP... keeps bootlooping over and over...
I have a JTAG 10pin to DB25 cable, bought in the past for Motorola SB5100 modem, assuming Blackcat, can I use this cable to make connection to serial console TX, RX and GND?
many thanks for your help!
bought USB-TLL adapter for 4USD and flashed through Serial console, working fine again, though I'm wondering whether it's normal to see message "No valid address in Flash. Using fixed address" in Putty log?
