Yes i perform the combo over network settings and checked the flag set.
Yes I renamed the update and placed in PS3/UPDATE. same i did before updating to OFW 3.55 and then to CFW 3.55
Yes I am updating using recovery menu. i have updated to OFW 3.55 and then to rogero CFW 3.55 v2 via recovery menu
Yes I have perfored the MD5 checks and all were matched.
please advise whats wrong? i have done everything according to your steps. i think i must go back to OFW 3.55 from rogero CFW 3.55 v3.7 (CURRENT) via recovery menu and then to rogero CFW 4.30 v2 via recovery menu. in short, 3.55 ofw to cfw 4.30 v2. but your advise would be great.
