I have updated two RB750UP ros 6.43.2, when I try to update the firmware the RB stops working and needs a full reset.

The current firmware on board in 3.19, I would like to upgrade it to 6.43.2

I tried a search on the forum but I did not find any information.

I add:
at every reboot I have to completely reset... it is not normal!!!

Hello, I have same problem with upgrade firmware on 750UP (i have 30 routers). I try to send this problem in Support with [Ticket#2018100822005227], but they recommend to use NetInstall. It's not working for me. I noticed that after upgrade firmware eth led began fast-fast blinking.

same here 2 rb750up

we had to netinstall them with 6.42.9, no more tries with 6.43.xx for a while for us

I have similar problem. but with RB751u-2hnd. this RB is previously hacked with coinhive-virus.

I can update 750UP to 6.42.10 firmware with disabled poe and firewall.

We have detected these problem with more than 5 RB750UP. When we try to upgrade firmware then it not starts.
