Reflash 1.5?

[ACID]

Or use STX version changer and just update to 1.5 without going to 2.00

But it wont bee a clean problem free version.

Ya it will. STX changer runs on 1.5 and tricks it to 1.0. Then you use Sonys 1.5 upgrader to upgrade.

Could you not spoof 1.0 using X-Flash and trick your PSP into upgading to 1.5?

[Kramer]

The only way to get a true clean 1.5 is downgrade to 1.0 then up back to 1.5

Im pretty sure anyway.

Bottom Line!! Upgrade 2.0 And Downgrade 1.5, Or Downgrade 1.0 And Upgrade 1.5. Either Will Do!!

[HAMMIEZ]

upgrade to 2.0 then downgrade to 1.5 is the safest i think.

[splodger15]

I think its best to downgrade to 1.0 hen update to 1.5 but anyways it doesnt matter there are both the same really

[TheRealShin]

i would downgrade to 1.0 that upgreade to 1.5 the easy downgrader at psp hacks is the way to do it but thats just my thoughts

[Video_freak]

Ok, let me clear it up for you guys. They both do the same thing! If your on 2.0 and downgrade to 1.5, the hack makes it think it's running 1.0. If your running 1.5, the hack makes it think your running 1.0. It all comes down to the same exact thing! Neither is 'safer'.

If you have custom firmware, you can get the index.dat from the MPH downgrader and then put that in the root of your memory stick.

And then use the option to flash the index.dat to flash0 in the recovery menu.
