Cannot get out from factory/service mode, faulty right usb port.
First of all i used PS3hax tutorial and E3 flasher to make downgrade for PS3 slim CECH-2503B, everything seems good until i tried to get in service mode.
I put e3 card reader into right usb, pressed power and eject, e3 card reader blinked red light, but nothing happens(PS3 boots and shows connect controller).I remembered that right usb slot did't worked properly,because whe want to check min version ps3 did't see the files on right usb. So tried to put e3 card reader in left slot. Then it blinks reed and blue lights and turned off. After this i put files from service mode step1 into USB stick formated FAT32 and putted in ps3 left slot, lately right slot but when ps3 turns on and after 5-10 seconds it turns off(nothing on the screen). I tried to solder wire SBE to TRISTATE and using E3 flasher and flashfun mode write patched bios, but when i turn it on still the same: turns on and after 10seconds turn off. Any ideas how to repair this thing? Thanks for answers.
