Linksys WRT54G V6 Bricked

Post by X-TraxxX »

Hello Fellow Members

I have a Linksys WRT54G Bricked Router. Currently using a USBJTAG NT to debrick. I already have a save full 2mb backup before the brick happened.

Router has a Intel JS28F160 C3BD70 A6227324 Flash Chip on the PCB.

Software connection Config: Router -> EJTAG -> WRT542M

Here is a log of what I have done so far.

Code: Select all

Unknown Flash type! seems to be the issue here. Any idea's on the next steps to take?
