    I'm not really entirely sure what you're trying to say but 2.50 can be upgraded to 2.71, just go to www.psp-hacks.com and get the upgrade. Then 2.71 can be downgraded, check if you got a TA-082 mainboard (I think that's what you mean with "new chip") and if so, use the TA-082 downgrader, if not use the normal 2.71 to 1.50 downgrader, they can all be found on psp-hacks.

    2.5? Are you sure? I don't remember a v2.5 software, only v2.6.

    Anyway, upgrade to v3.03, then downgrade via GTA:LCS unpatched from there.

    Yes there is a 2.5. Try not to repeat what other people say it makes you look a spam whore.

    Guys, why upgrade to 3.03? 2.71 can be downgraded without using GTA:LCS unpatched, which is quite hard to get these days. Also there are no remnants from 3.03 FW left in the flash, so a chance of bricking is even lower.

    Before you do anything, check out this picture and tell us if you have a TA-028 motherboard in your PSP.
    If you are not on a TA-082 motherboard, do this update and use this downgrader. If you use this, be aware that you could brick your PSP, so read the readme file for the downgrader and follow every step. By the way, use the 32 MB memory stick that came with your PSP for the downgrade, not a bigger one. With no real explanation the exploit seems to work better with the 32 MB card than with any other.
    Don't do anything if you are on a TA-082 motherboard.
