Hi,
I have a problem with a new C3850 48p POE+ Switch, at first it came with IOS Version 16.x.x and it was working fine. but I wanted to add it to a stack. The stack master was c3850 48p and was runing ios 03.02.03.SE so I enabled auto-upgrade on the master switch then I added the new switch to the stack with full ring. Everything was ok then the new switch rebooted so it will use auto-upgrade to downgraded from 16.x.x to 3.2.3se. while its rebooting I saw a fail msg and then the switch went into a rebooting loop until it said Auto reboot is disabled and I got stuck at ROMMON mode.
Now I removed the stack cables and wanted to return the new switch to be operational again but every time I reboot it just go straight to ROMMON mode. I tried to reload new IOS from USB flash but it keep failing and I cant copy anything to Flash:/ as it says it REAN ONLY.
I'm currntly stuck here and I have no idea what to do. I searched many solutions but all failed.
Pls see the system msg below :
