Greetings!
Ive upgraded many routers to 6.43.1 (OS + firmware). Today one of RB2011 was rebooted and didn
t wake up! I cant see it even using netinstall. It seems to be an endless boot cycle... By the way, the router made no sound till I
d used a “curcuit” reset instead of button.
Please, help me. I`m afraid that my another routers will do the same.
And:
I have two bricked device after flashing with 6.43.1 firmware. sxt lite2 and groove5 in bootloop.
