Cannot Upgrade/Downgrade after 6.0b1 installed...

I have a rb1200 that I put 6.0b1 on to test. Now I need to put this router into production, but it will not accept any other firmware. Can anyone provide any information on how I can fix this? For all other updates, I have always been able to just drop the FW file into the file folder and reboot. THANKS in advance!!!

to downgrade, you need to select ‘Downgrade’ instead of just rebooting. what’s in Log?

nao versao 6.0beta2 rb1100 nao está fazendo downgrade

Hi, i have RB750G and upgraded it to 6.0.rc6.

After the upgrade the internet traffic on eth1 start droping every 5 min for some seconds.

I try to downgrade the router from system–>packages–>downgrade and reboot

but there is nothing after restart is the same version.

Can someone explain how to downgrade to previous installed version

or if i upload files of version 5.22 and reboot , will it downgrade the router?

I have bad eng but sorry i hope you understand me.

no, first upload the v5.22 NPK package, then click “system → package → downgrade”
