Accidentally formatted hard drive running CFW 3.55 Cobra -- black screen
EDIT: I have a PS3 Slim - CECH-2501A
I had Cobra installed (with purchased USB) and running CFW 3.55 successfully no problem. I formatted my hard drive by taking it out of the PS3 and hooking it up via USB to Sata and it formatted fine. I made it a FAT32 partition and stuck it back in my PS3. Then I tried to boot it but cannot get video or audio... on any cables -- HDMI, Component, or RCA. I tried the video reset trick as well as recovery mode -- neither provides video or anything promising.
I assumed maybe it was a coincident and the RSX chip became loose on the board so I had the PS3 reflowed by a friend who has done it two times and been successful each time -- no luck.
My question is, is it possible that NOT REVERTING BACK TO OFW 3.55 before formatting the PS3 in my PC could have cause the issues I'm seeing? Keep in mind I started on kmeaw 3.55 and quickly got Cobra FW with USB. Then forgot to get OFW 3.55 before formatting.
Please let me know if you have any questions.
