**sseraphh** · November 17th, 2007, 09:18

I am still have 3.30 OE_A2 firmware in my PSP. Could I just straight away upgrade my PSP to 3.71_M33 or I have to upgrade it to 3.52_M33_3 then to 3.71_M33? Need advice. Thanks.

I am quite new in this m33 firmware...so where can I get this 3.52 m33_1 to 4 files and must I update the files each time?

no... go to 3.52 m33 and then to 3.52 m33-4.

I say stay in 3.52 m33-4, it works well... 3.71 m33 can brick or semi brick the psp, if you are not lucky

What u mean is that I can just upgrade my PSP to 3.52 M33 first then straight away to 3.52 M33_4 without going thr the rest of the 2 and 3 update right?
