I've got a CECHG model currently on 3.55 and I'm trying to downgrade it to 3.30 so I can remarry a new logic board to it. I flashed my XPLAIN with PSGrade and can get into FSM with no probs. However, when I try to downgrade to the modified 3.41 FW, it fails during the flash and semi-bricks. The only way to fix this is to rerun it with the 3.55 OFW and the Lv2Selfdiag file, which of course, brings me back to 3.55 Any help would be appreciated. Note that I can not run any apps (QA Flag, Multiman, etc...) since the logic board isn't paired to the motherboard yet, no apps will run. Thanks.
