ok here it is first switch on psp and map out the keys that get you to change the colour setting this is very handy later, now find a very good MMS maker with pictures to guide you though the way, put MMS in PSP, Now hold right trigger button down put in pandora and press X X now you are in the pandora setting (nothing is dislayed on screen) it flickers slightly now the good guide will help you (your flying blind for a bit follow your guide VERY carefully) as the guide tells you when to do something you need to select all the options as exact as the MMS guide tells you. Whle flashing the psp the blank sceen filckers when its done you get a flash of colour and its done press x. now for the freaky bit when you replace the pandora and start psp the screen is white and you think its ****** its not you need to change the colour settings as the screen text icons will all be set to white, i watched a friend prove he has a TA-088v3 with pspident and flash the firmware, key is making sure while you can't see the options you choose the right setting, please like all other guides do so at your own risk. im sure someone can shoot this down in flames but it worked for him and i thought id share the update, apparently this has been around for a little while, i only just found out, about it.
just done one, pain in the arse when the screen goes all white but my sons is done, its easier to have a second psp to map out the stages to changing the colour. Over the next couple of months im gonna get this guide shot to ****. it's not a problem everyone is welcome to put there opinion here, i would prefer it if it was objective and not bickering sarcastic or done out of malice. I did use an MMS and PANDORA battery and was worried that because im moving the D-pad up and down without seeing the options i could do something ill regret like nand dump, thats why i needed a guide to have detailed pics and took the chance, this could easily mess up the psp so beware, clever people at sony left the ability to boot into service mode just disabled the screen making it look like it didn't work, no doubt someone will figure a way to get the screen working in future to.
not at he mo, i watched my friend do my sons while i was over his house, next time i find someone with the mobo mentioned i will video it.
Make sure you do plenty of research and are happy before you try this don't rush in
