I found that 2205 zip Blitz file on one of my drives
I am pretty sure but not positive it is for the P9983. (Blitz os 10.3.3.2205). I have it on my desktop but can't figure out how to send this 2 Gb file to you.
But to go back to a previous rev may not be possible unless you do a total wipe (which I had to do). I found multiwipe 1.2 on my pc also and if you cannot install the blitz file then you will have to do a complete wipe (using multiwipe) (factory reset does NOT do a full wipe) then autoload the blitz os 2205). Not for the faint of heart though.
