You can Update: You patch a retail firmware for shop. You add promo_flags.txt with a value of 0 and change Update_flags.txt to 0300 on the root of the firmware after unpacked then repack it. Get PS3 MFW builder, then go get 4.11 Retail firmware off sonys website. open up the program target the original firmware to 4.11 retail and the modified to your flash drive with the folders lined up like this PS3/UPDATE/PS3UPDAT.PUP if you do not comprehend what this means Ps3 is a folder on root of usb. so is Update. then inside update folder drop the update file. in the mfw builder go to patch firmware for installing shop/promo unit at the bottom of the list. then remove the string flag that says promotion-to-retail make it blank keep patch promo flag and update flag checked. then buuld the firmware. after its done properally eject your usb from your pc. Put in the ps3 and go to system update and check via storage media. then proceed. farily simple. Firmware is not hardware deep. is basically converting to work....
