I am having SONY PSP of 2.6 version. What advantages and disadvantages of downgrading / or upgrading to 1.5 or 2.8 versions respectively?
Once down graded from 2.6 to 1.5 can I upgrade to 2.6 and 2.8 version again? or is it irreversible?
After 2.60 there were 3 updates cames from Sony ie 2.70, 2.71 and 2.80.

Downgrading actually means that u r fooling around the PSP , so the PSP thinking that its a you are having a 1.5 instead of 2.6. You can upgrade anytime. But Once you upgrade from V2.6 at present there is no downgraders available. So its up to you whether you want Homebrew apps or not.
Also you have to check for the mother board type before downgrading
If you have this mother board above, there is no downgrade from v.2.6 possible. To check the mother board eject your UMD drive and look for the Number IC10003 in the mother board. If you cant find that then You are not having TA-082 Mother board and your PSP can be downgraded from 2.6
Advantage and Disadvantages:-
If you downgrade you can use Homebrew application , ie softwares and utility items created by third party developers which is not supported by Sony. You can use pirated UMD movies which saved in ISO format and you can play it from Memory Disk
At present You can Play Online games with the use of your homecomputer
GPS is available
Lots other games can be played developed by other developers. like mario, pcman etc
and lots of developments from these developers are coming........ who knows whts next !!
Disadvantages: You are risking your PSP by downgrading, There is always a chance of bricking your PSP ie while downgrading u r PSP may become dead. Your Warrenty get void.
But there are lots of people who uses the downgraded firmwares to get the most out of PSP.
Sony used to upgrade the firmware and gives us new features. So if you decides not to upgrade you wont get this facilities.
