Can i downgrade a CECH-2503B to 3.55 and then install Rex or would it have to be CEX? If i can downgrade it?
On it has 4.80 OFWHeya @Benbow2002, a good place to start is to check the Downgradable PS3 Models & Base Firmware with MinVerChk thread.
It looks like originally it had 3.40 or 3.50 OFW on it, what Firmware version does it have on now?
I remember all the horror stories back in the PS2 days with those Sperry / NeoAsic clips, Magic / DMS clip kits, etc... and technology has only gotten more compact and precise since then with PS3 and PS4.I can't stress to people enough to stay away from the clips for flashers.
