Can't return to 1.5 after using custom fw..

[shadow_link]

I've installed a custom fw which "supposedly" boots to 2.71 when you press L when you load and 1.5 if u don't..

But after i've installed it, when I boot my psp up there's just a black screen...

Sure it boots up to 2.71 all right but that defeats the purpose of having a 1.5 :'(

I've tried pretty much everything...the recovery mode (which doesn't work..or at least nothing happens when i boot my psp w/ R pressed), return to 1.5 homebrew (black screen again)...

so what is my problem??

ok this usually happens when u don't remove the previous CFW and install another one, did u have CFW before u tried using the one that's giving u problems?

also in recovery mode look for something that says "remove custom fw" or get Slasher's CFW unflasher, recovery modes the easier way though

um...so what's your problem again?

[shadow_link]

no this was my first CFW... and i can't access the recovery mode at all...
Do i need a file or something on my mem stick?
Also i can't access 1.5 at all so i can't run the unflahser..

what version of devhook do you have, because if you downloaded v.46 then it should have come with a folder called something like "return from 2.xx to 1.50", that folder would be placed in the GAME folder and if you click it while in the emulated 2.71 it would return you yo 1.50

he has done what mr shizzy did to his friend, parially bricked the psp, only solution mr shizzy found was to have autoboot set to irshell

(the only way to install custom firmware without this type of brick is to make sure your psp is at 100% charge and is plugged into the power , and if you are really unlucky you might still have a brick as it writes to the flash)

i have .46 and yes i've already tried that w/ pretty much no result lol..
i've tried to take an extreme measure of trying to update to 2.8 which i couldn't since i'm still emulating 2.71

anybody knows what files u need for the recovery mode to work?

these are the threads mr shizzy started when he bricked his friend psp (except he used harleyG custom firmware nor DAX's POC custom firmware)
like i said before only solution he found was to autoboot irshell

have you also tried to install the plugin in the 2.71 folders that will let you return to 1.50 by pressing both home ans start?

[jak66]

motoko, he has messed up a crutial file on his nandflash, that is the reason it refuses to start up 1.5 no matter what he does, as for that plugin, all that does is restarts the psp (if you leave wlan down with harleyg custon firmware, it boots back into devhook, lol)
