ER-301 Stuck on "Looading Settings"

Hi everyone,

My ER-301 getts stuck on “loading Settings” . It looks like it’s gonna do it , going through initial 100% animation then it stops at " loading settings…" screen with only A3 LED lit.

I moded and connected 2ic to a pannel mounted TRS socket, it never worked but er-301 did boot up as normal at first then it suddenly started doing that after powering my system when trying to figure the setup with MSW XVI. One thing I did just before this started happening was hot swap 2IC sockets on XVI .
