R6900v2 flash complete but power light stays amber #146

Open phdfloppa opened 5 months ago

Trying to go back to stock firmware. Previously had OpenWrt installed on the router.

Having similar issues to this user #140. The router turns on but the power LED stays a solid amber color. Seems to be bricked. If I turn on the router by holding the reset button first, the light turns amber and then flashes white. I only have the power plugged in and one ethernet cable plugged LAN port 1.

Here is the full output log:

Also, try setting your computers IP to 10.164.183.252, and try pinging 10.164.183.253. These are the IP addresses used by nmrpflash by default - maybe your device "remembers" these addresses?

From #140: Have you tried this?

What should I do, specifically? Should I use nmrpflash, reboot the device, then change my IP to the first one ( image ), open cmd and type ping 10.164.183.253?

Exactly!
