Thanks, do you use the NAND clips or you soldered?

And what firmware did you successfully downgrade from last?

I have a clip here, but its not save enough for me. I solder the progskeet directly to the nand. I downgraded 3.70, 4.00, 4.10, 4.11 till now and that many times. No problems. I use always only the patch 3.55, works for me every time.

I presume you only get 42 or 43 blocks modified on each NAND right? For I get 46 on average and then YLOD

Hi guys, i'm having some troubles with a ps3, got all the dumps patched and flashed back, when i power up the ps3 it goes black screen and then off after 15 secs. i'm using psfreedom as jig dongle to enter factory mode but when i plug it off and plug in the usb key with the self and pup files, the usb doesn't seem to be powered on by the ps3 and after a few secs the ps3 shuts down. i tried both patches with the same results with and without with no luck.

When i plug in the dongle the ps3 stays on for a few more seconds, i guess because it's actually working, i'm using progskeet 1.1, forgot to mention that i tested the dumps flashing them back and the ps3 was fully restored, i'm on 4.11 currently.

Hope someone can point me in the right direction cause i'm actually lost on this one

Thanks in advance

Got everything sorted out, it was a faulty jig dongle, just used another one and worked flawless, thx again for the amazing guide

Looks like this is the solution for downgrading my CECHG PS3 in 3.60 OFW to 3.55CFW
