Alright my friend bought an e3 flasher for me to downgrade his ps3 to 3.55 only to find out that his ps3 wasn't able to so he gave it to me.I know it can work with my CECH-2001A system so i decided to dual boot it.I was on 3.55 cobra with my original 120gb hdd and backed up my bios with both the e3 flasher and the dump_flash.pkg file.They are both clean working version.Next i tried to put the cobra bios on the e3's nor chip but it wouldn't let me so i knew i had to update to 4.11 (i also backed up my 4.11 bios and it too is clean and working) then downgrade back to cobra.The problem is i used a 3.55 bios with the downgrade.bin file while on 4.11 and now it wont power on all the way even though i did all the soldering that needed to be put on the motherboard.Please if anybody can help i will stop dropping tears.I dont want a fancy doorstop :(
