1. with usb flash downgrader
2. with PSP.
THIS WILL WORK ONLY ON 3.55 OR LOWER !!!
I personally did with PSP.
Thanks Pereb27, I tried to "reball" the BMD-002 A4 "key" to the BMD-001 A3 with no success, either I did it wrong (most likely) or it just confirms your estimation of compatibility. I should have read this first. I need to do a downgrade on the firmware so I can remarry a new board because I wrecked both of those boards. As for the CECHE01, I have swapped the power supply which still has the same symptoms. It gets power to the majority of the system. There appears to be an issue just before it enters the Blu-Ray. I actually used a working machine and strung the molex four pin connector over to the CECHE01 which actually let it function enough to launch a storage CD backup. Just no Blu-Ray or DVD would come up. I check the power with an Digital Multimeter. It shows up on either side of the molex with 12 volts? on the black wire and 5 volts? on the opposite white wire with 0 on the two center wires...I just wished I knew what I was doing (LAME)! Thank you again.
I don't have a PSP, but I do have a usb flash drive. Do I have to do it in increments or can it be downgraded immediately to 3.41? By doing the downgrade, will it erase my passwords, downloaded games etc...?
