Just asking about FW
 

Hello my PS3 is 4.11 I hope you dont mind me asking . I saw that is important what model is your PS3 for downgrade so my question is : Does it matter that my original ps3 firmware was 3.15 then I upgraded to 3.41 (using USB hack) and then to 3.55 kmeaw and I accidently upgraded to 4.11 ? If similar topic exist I'm sorry i didnt see it :)

Yes it does matter... by stating that you already answered your question... your ps3 is hw downgradable :P

tnx man :) is there possibility to do it with software because in my country I cant buy E3 flasher from any store and Im not the biggest fan of online shopping :)

nopes hw only... there is a big banner in the top of the page that if you click on it you will have all the answers...

About online shopping... lose the fear... there are serious people in the tubes to...

Maybe some other member could point you to one of those online ressellers...

@r07f1 is correct, there is no way to software downgrade. You are going to need to obtain a hardware flasher (dependent on your PS3 nand/nor) and a FSM (factory service mode) dongle.
