following problem: IŽve downgraded a friends PS3 from 3.55 back to 3.41 ! All works fine, till now. WeŽll update to 3.56 and we get an ERROR!
When weŽll update from diffrent USB drives, it says that the UPDATE.PUP is bad. Same when we download the file directly from the internet to the PS3. Now weŽve formatted the HDD and still same...
What about Service Mode and reinstall 3.41 then back out from Service Mode and trying then to update?!
Any other ideas?! Or same problems?!
Thanks for helping me, greedings!
