How to downgrade psp 3000 vision 6.10 to vision 5.03

dont try to downgrade because you will corruptyour hard drive in your PSP-3000

There's a way to downgrade it now. Datel released a new battery called the Light Blue Tool. Similar to the previous Datel Tool battery, it puts the psp 3000 into service mode where it can be downgraded.
If you have a Magic Memory Stick, then you should be able to downgrade just like you could with any other psp...

I am afraid this is not possible, if it is a PSP 1000 or 2000 you would need a pandora battery. However if it is a PSP 3000 upwards there is no way to downgrade the firmware at all. Anything above firmware 5.03 is not possible to downgrade on a PSP 3000.

Hope this helps

You can not downgrade PSP 3000 but can downgrade PSP 1000 and 2000.

Secondly write your question clearly.

PSP 3000 can't be downgraded but PSP 1000 and half of PSP 2000 can be downgraded.

Please do not try something about which you don't know or your PSP 3000 could be bricked.

PSP 2000 CAN BE DOWNGRADED BY PANDORA BATTERY BUT "NOT THE 3000"....AND PSP 2000 CANT BE 3000..............!!!!!!!!!!!111

if your firmware version is 5.03 or below it can be downgraded, if it,s above that it can not be downgraded as on now because the cracks available works only for version 5.03 or below. there are plenty of tutorials in the net if you want to downgrade your psp by yourself or you can bring it to a game shop which offer downgrade/upgrade or modification of psp.
