the 2,76 ofw has got otheros already m8 if you go past 3.15 i think that when sony took it away lol but then it been brought back to 3.55 or lower so no need to go lower

Downgrade it too The First Filmware 0.00

My Bad Man, I am sitting on 3.21 ofw. Anyway to downgrade? for shits and giggles would like to actually put it back to the original fw that came on it.

ya i think there is m8 but am not to sure how to do it m8 i look for you if you want but all you really have to do is look on google or here on ngu m8

I have been looking on google all the ps3 sites and forums, but i'm just missing them i think. thanx for the help bro!

it might work downgrade lower firmware m8

First you must put your ps3 into factory service mode.Next,start you ps3 with your flash drive plugged in with the Lv2diag.self file 1 and your desired FW pup on the root of your flash drive.Your PS3 will go to a blank screen and your flash drive will light up.Wait for your ps3 to cut off(usually takes like 10 min.).Delete file 1 and .pup off flash drive and put Lv2diag.self file 2 on root of your flash drive. Plug flash drive into ps3 and start up.Wait for ps3 to turn off then take out flash drive.Congrats you have successfully downgaded FW. Also if your downgading from 3.55 or 3.50 you must use the modified 3.41 pup before downgading even lower.
