You have to get a hardware flasher and then go through a guide to downgrade it. Thanks

why the heck does almost every nand ps3 have bad blocks ahhh... tried 3 in a row now and non of them is reading the damm pup file after i get it in service mode (tryed 5 usb sticks and 3 harddrives). service mode is working but it wont read the pup is that because of the bad block?

i have made 1 whit nand without bad blocks and that worked like a charm but not the ones whit bad blocks is there anything that i can do ore is it just bad luck and they cant be downgraded? sorry to post it here but i need a little bit of help

I was wondering if this service would benefit me?

Thanks

Hi racer, i think i need help today i installed the REBUG_4.30.1 from 3.55cfw then read i could use REBUG_3.55.4_999_DGR as i wanted to go to REBUG_4.21 but it would not let me do this i got error codes you name it i got it. now i dont have nothing cfw folder on game area, i think i need help to downgrade it.

is there anyone in the uk that can downgrade my ps3 please back to 3.55 ?

[racer0018]

This is what i would try.

Make sure the ps3 is q&a enabled. To do this you can do this from the rebug toolbox. It is the last option at the utilities. Also make sure that under rebug settings the systems update debug is turned off. Then install downgrader 9.99 under recovery mode. YOu will know that this installed correct cause there will be a user agreement from sony. After that then install again from the recovery mode rebug 3.55.

You may have to repeat this a few times for it to work. after you are on rebug 3.55 q&A the ps3 again and make sure system update debug is turned on.

thanks and let me know
