put one about the 2.60 there's a guy who needs it
well the 2.6 downgrader requires GTA whereas the 2.71 does not. anyone who is on 1.51 - 2.70 should just update to 2.71 and downgrade.
what do you mean? the guides cover all motherboard types (TA-79/81/82/86)
there needs to be a 3.03 downgrader that dosent need GTA its hard to find GTA (unpatched) now days

All the guides need to be updated to link to the corruption-free downgraders (in the development forum). By leaving the guides set to the original downgraders, TA-082/86 people continue to corrupt their PSPs. Yes, there are some tools to help fix the PSPs afterwards (also in the dev forum), but it's better to not break the PSP in the first place than to break it and then fix it. Also, the guides don't mention the corruption or refer people to the fixer programs, so many people continue to blame the custom firmware for issues related to the downgrader.
that's true. I will update the guides later on today.

2.71 as always...
Upgrading to 2.71 and then downgrading to 1.5 is still going to be your best bet (especially if there is no writing in your UMD drive).
For best results when performing ANY upgrade/downgrade on flash REMEMBER:
Before you start it's not a bad idea to Restore Default Settings in your PSPs System Settings.
Be sure to use only a good quality memory stick and Format it in your PSP before beginning.
Have a full battery and even plug in your wall adapter for good measure.
And of course NEVER INTERRUPT THE FLASHING PROCESS!

save the file as "EBOOT.PBP" and place it in the X:/PSP/GAME/UPDATE directory

Yeah place the 2.71 EBOOT in:
X:/PSP/GAME/UPDATE
Then run the update from your game menu.
