Hello,
I was upgrading my core router x86 ver. 6.21 or 22/23 not shure to current version 6.34.3 over Winbox, Package list download/upgrade! After update it seams that everything is working but I cant login !!!
Winbox gets stuck on Logging in
SSh access denied
I tried serial, I did able to get connection but my user name and password denied
webinterface is disable
every time I do ugrade on this custom x86 something gets scrued, what can I do now pl help !
Thank you!
Netinstall the hdd to reset the password.
I Never used netinstall , I can reinstall RouterOS but I whill lose config ?
Why did my password scrued up , last time I upgrade OS crashed, but only my x86 gives me these headaches!
Netinstall loses the configuration. Hence you being able to login afterwards.
I could not brake loading OS over serial to eneter bios or boot loader and try netinstall, maybee I did something wrong.
In the end I needed to reinstall RouterOS with CD, only way for this x86 that works, no more upgrades 
!
