Dead RB750 after upgrade to ROS5.0 rc1 ?

Hardware MikroTik hardware general

I have a RB750 which was not usable after i’ve upgrade the ros to 5.0rc1. It’s not detectable using winbox and netinstall. I’ve done the below but nothing helps.

  1. Resetting the routerboard
  2. Swap psu with a spare one

Any ideas on how to solve this? TQ

Did you see what happens in console?

That’s an epic fail for such answer. RB series 700 doesn’t have RS232 (as for 750/G and 711).
