my downgrade history.
1. dump 3.70
2. downgrade E3 Flasher.
4. Recover 3.70
5. PS3 Working.. Update PS3 to OFW 4.00
looks like it works alright, my bad there.
i was in the understanding if those new models brick its perm-bricked
with a good dump 3.70 u fixed it.
now u should have asked yourself...hmm wassup?
... i know its easy for someone else to say and also bricked his first one hehe
updating the OFW to 4.00 wasn't required but no problem ofcourse
then it goes wrong somewhere but i have no clue really... i'm sure someone have a fix for this.
