3.51m33-4 to 3.71 ERROR

[anteopimp]

I recently updated my bros PSP Fat from 3.51 m33-7 to 3.51 m33-4 (only to upgrade it to 3.71, then 3.80, then 3.90). So I made everything right and as I boot up the 3.71 Update it says "This version is only for 3.52 m33-3 or higher. Since mine is higher... I don't know what to do... Can anybody help me?

are you using the one stop update thing in one of the threads around the web?

Go into your recovery menu

and change the kernal to 3.52 if its on 1.50

that should fix your problem

[jxx2005]

you can only upgrade to 3.71 and higher if you have 3.52
not 3.51
upgrade to 3.52 then go from there

i dont know how you think 3.51 is higher than 3.52
