I have a CECHA01 ps3 that i tried to downgrade. green light blinks forever, i get error 0x8002f14b in hte jaicrb log. using lvl2diag file 2 doesn't work either, system turns on then abruptly turns off. Fix PLEASE!?!
OK nvm solved, whew that had me worried. Diffrent question: can I downgrade all the way down to firmware 1.0 without soldering anything?
