How to update my Sony PlayStation Portable to 5.50 gen d-3

your psp is bricked

you can just download it and you put it on the psp mmc and update that is all there is to it
you can download it from HERE

no when you update past fw 6.0 you need to wait till next year for a custom fw for GEN D6

Your PSP may be bricked. Send it to Sony to get a replacement if warranty is still available.
Next time, when you update, plug in your PSP to a wall outlet to prevent this from happening.

if you have version 5.03 use the chickhen r2 and gen-c updater to play iso/cso games.

So degrade again ur PSP to 5.05 Gen D!

Download is FREE! In any PSP downloading site!

For PSP 2K put a 5.03 gen D!
For PSP 3K put a 5.05 gen C!
Now start downloading and playing games!

Note: only for version 5.03 GEN-BStep 1: go to restore default settings, psp will restart Step 2: go to themes, change the color to white Step 3: This is the tricky part... go to photos and press down(don't let go) then press x.., your psp suddenly crushes and restarts Step 4: run the 2 programs on the game folder ... CFWenabler then the 5.03 GEN-B Updater.... Your welcome...

Your need to download the ChickHEN and CFW GEN-C 5.03 update from the internet and install it in the memory stick of your PSP.
