First of all, have you checked the
1. Minimum version of the ps3 ?
2. Have you confirmed that it is a NOR and not a NAND chip ? I see that you are using e3 flasher that can ONLY be used for NOR and not NAND consoles.
I personally recommend using flow rebuilder and choosing the "PATCH a Byte reversed NOR dump or an interleaved and unscrambled NAND dump." (Last but one option) and patching with "progskeet_patch.txt" patch. This is how i have done all my 166 ps3's so far.
Also downgrading is not a easy job. It totally depends on the luck of the day. There are times where i have not got a good dump even after re clipping 40-50 times... So best of luck. Read ps3 dev wiki properly for validating nor dumps.
