First up, my small psp history (to clear anything up). i have 2 psp's. the first one i got brand new, never dropped, perfect condition (except the wireless thing isn't working, i think i overclocked it to much when using wi-fi), had for about a year, 3.10 oea2, not a TA-82 or TA-86, no custom waves, fonts, etc have been put on it. the second one is basically the same except it was second hand that i got after the first one had the problem with the MSduo, not in every good condition , not a TA-82 or TA-86, 3.10 oea2, no custom waves, fonts, etc have been put on it, i think its a earlier motherboard then the first, wireless works. i also have 4 MSduo's:32mb(came with first psp), 1gb (sandisk,see-throw fluro yellow),2gb(sony high speed,possibly a fake), 2gb(sandisk, not see-throw, blue)
Well now u know my psp's lifestory, the problem is with the first one, When i put any of my 4 ms in it doesn't show up on the xmb and the ms light flashes about every 3 sec's after i put the ms in. all 4 of my ms work perfect in the second psp and all of them worked in the first before the problem started(that was about 2 weeks ago). i also put all 4 ms into a friends mobile and hooked it into my computer and all 4 were fine. so the problem is with my psp not the ms (just to clarify)
the reason i want to fix this is so that i trade one of them in to get some $$$ but i also want to keep one. and when i trade it in i would like it to have official (sony) fw on it and how am i meant to do that without the use of a MSduo (that was question 2 btw)
*EDIT* My wi-fi was screwed for more then 6 months before the MS duo problem started.
