Hi i have PSP Model-2006 i have updated to 5.50 GEN-A Build4 Custom Firmware after installing it is Bricked i can't see any thing on screen only GREEN LED glows, i have created MMS using RainMMS & inserted it in PSP after that Holded L trigger & inserted my PANDORA Battery ( Every Body Says Memory Stick LED & WLAN LED will Blink) but for my PSP it is not Blinking or i did not find any menu loaded i have also tryed with Universal MMS but no use so what i have do know is there any other way to unbrick my PSP please help me.
I think you have one of those TA088v3 motherboards that can't be unbricked yet. you shouldn't have tried to install permanent custom firmware ... btw what was your cfw before you unbricked your PSP ?
Before Updating to 5.50 My i have updated 5.01 Offical Firmware, but when i have got my PSP it has 4.01 Firmware
You have an unhackable motherboard, and you have attempted to hack it I'm afraid the PSP is bricked...
