My blew up like this too. I set the rom to OS-B and 1 Meg and on write it died and my 800XL is now a brick, even if I put the old ROM and MMU in. 
Sorry, not help, just commiserating.

I got it to boot with syscheck v2.2 with flash jumper on i can boot only flasher ANT.EXE complains about cartridge.
When jumper is off it boots fine without syscheck v2.2 only flash complains about write protected flash.
@drac030 can you help me to flash atleast 1 firmware in my antonia ?

Yes yes

After playing with syscheck I finally got ant.exe loaded and slot 0 did seem to have a valid os. i had to set mode to 64k because that was offered by syscheck.

Got it to flash again
