I've a small problem with TFTP Firmware flashing.
I've got two WRT1900AC v1 where at both the power lamp was blinking, so I tried to TFTP flash them as described at the wiki.
With the first everything was ok, but the second one will not flash.
The router connects to the tftpd32 server but the transferrate stands at 0 B/s and nothing happens. After a while I get an 'Undefined error code' (0). Afterwards the NAND is erased, which is "ok" and then the NAND is written again which also leads to an "ok".
Can someone give an adwise how to flash the router now?
Thanks!
If only the WAN light and power light comes on, with the wan blinking, the bootloader is corrupted and the router is hard bricked. If this is indeed what has occurred, you can try the bootloader recovery in the wiki.
You can verify this by using a usb - ttl cable, opening a serial terminal, and then watching the output. If everything appears as it should, it's not hard bricked. I've had a WRT1900 with the same issue [prior to nitroshit's bootloader recovery contribution] and it was still within the return period, so I exchanged it.
