Beware Of Downgarding

Submitted by Ewiz07 (not verified) on Fri, 2007-07-13 14:12.
3.50 Downwgrader worked!!! But Beware. After downgrading on a TA 079-TA 089 motherboard you will not be able to upgrade to 3.30+ unless you run a hombrew application that will fix id storage keys or switch your motherboard. All upgrades 3.30+ will run a standard check to see if you have downgraded and will not allow you to update. Take my advice im stuck on 3.11

I might have screwed it

Submitted by Guest (not verified) on Sun, 2007-07-15 20:34.
I might have screwed it up..if anyone can lend some insight that would be great. I updated to 3.5Hen properly but when i ran xy.z i got to the screen where it tells you about 75% battery life and then it restarts the psp at 3.5hen. Do you think i wrote over the eboot file by mistake when uptdating to 3.5? What else can you think of?

Lumines after the downgrade to 1.5

Submitted by Guest (not verified) on Fri, 2007-09-07 02:11.
Hello, Now that my PSP has been downgraded to 1.5 thanks to HEN and Lumines, I sadly can't play Lumines anymore. When the game boots up and I press start to start a new game, the screen goes red and the PSP freezes. Is the HEN still resident in memory ? And if so, how do I get rid of it.

to get Lumines to play again, delete the stuff in the game folder or use a different memory card :)

Hi. Thanks for the greaaat

Submitted by Guest on Fri, 2007-11-09 11:31.
Hi. Thanks for the greaaat help to whoever created this 3.50 downgrade. I think it's good from what I read here... At the moment I have a 3.40 official PSP but I didn't buy it as a 3.50(I bought it as a 2.71 ver)...in many words my PSP has a long story and once accidently I re-upgraded it to a 3.40 official ver. because I didn't have enough experience in dealing with PSP modding. So my question is, will I have an ISO folder created on the PSP's root (so that I can play ISO games) after downgrading it with this one????
