i have messed up one of my PS3 Slims 3 months ago when i tried to use "Half-Dual-Boot" with the E3... after flashing back the ofw backup and turning on the ps3 had nothing but the glod.
No Video, no usb-sync, no usb-power, no hdd.. .absolutely nothing.. tried to flash back the 100% Backup from the ofw.. nothing , tried it many times but this PS3 board or the NOR-Chip was fried up i think..
i have renewed thermal paste and i think i did not any of the beginners errors..
**** happens ;-)
no way but the hard way..
FAT PS3 / CECHC04 / COK-002 / 256 MB NAND
SLIM PS3 CECH2004 / DYN-001 / 16MB NOR with E3
