Points: 26.70 Donate | |  PSP Clean FW install from 2.60 Downgrade?
My PSP was originally a 1.50 when I bought it then I upgraded to 2.00 then 2.5 then 2.60 then downgraded to 1.50. I herd that the 2.60 downgrader was a unclean install and can cause bricks in ThemePSP. I don't want to use ThemePSP I don't want a modded FW but the unclean FW I might have makes me wonder. So yesterday I saw the PSP 1.50 to 1.00 Downgrader. Tried it it worked perfect but then I couldn't use Devhook 0.46 so I upgraded back to 1.50 with my Coded Arms UMD. Will this make my PSP have a clean FW install now after I upgraded from 1.00 to 1.50 with the official updater? If you want to know my PSP FW history is 1.50 -> 2.00 -> 2.50 -> 2.60 -> 1.50 -> 2.60 -> 1.50 -> 1.00 -> 1.50 -> 1.00 ->1.50 |

| | Member | | Join Date: Jul 2006 Location: Everywere Age: 15 | | | yes it would have to be because its an official 1.5 update and nice firmware history!!!. Im thinking about downgrading to 1.00 and upgrading again is it really worth it with the slight chance of brickage with downgarding?

Points: 21.55 Donate | | | after the downgrade (to 1.5) all the files that are used by 1.5 are replaced and all the files not used by 1.5 are just left there, so the awnser is yes it is better to reinstall 1.5 flash to clear everything up, on my psp homebrew wouldn't work properly after upgrading to 2.0 and back to 1.5 it works like a charm.

The 2.50/60 downgrader to 1.50 makes it "unclean" as you said, Correct. Ways to make it clean:
Update to 2.00 - Then downgrade to 1.50 using MPH Downgrader.
Use the firmware trick & make it think its v1.00 (my fave) and then upgrade to 1.50
The use of the "Official Sony Eboot" file will make all downgraded PSP's "clean" again.
The downgrader did its job, It flashed the PSP, There were still some traces of the "2.50/60" PSP that made it "unclean".
Hope this helps with your questions,
Thanks
