Downgrade 3.71M33 to 1.50 without pandora

I thought noobs couldn't wait for their 3.71 M33 (More like demanded it to be done) :rolleyes:
Maybe this is a lesson to STFU next time, be patient and READ THE README (or the news post for that same matter)

- Psp Slim: umdcache was allocating memory even when homebrew was launched, wasting memory that homebrew programs may want to use. Now umdcache module is stopped before it can allocate any memory, only in the case homebrew is launched. Also, memory is unprotected for user memory usage by M33 core (only when homebrew is launched). Developer, for a sample of how to use the extra memory, see the extra ram sample of the M33 sdk.
- Both version boot now from 3.XX ipl, and are independent of 1.50. The main installer will not install 1.50 kernel anymore. A 1.50 kernel addon for 3.71 M33 that will install inside 3.71 M33 will be released in a few days (for fat only)

isn't this the normal downgrade process, but from the XMB instead of recovery ... ?

Hm... we couldn't do this before?

Oh, thinking about it... no. Thanks! Awesome.

ahahaha, awesome...this is 'teh noobz' 3.52 downgrader, not a new one for 3.71 at all

Jak66 I'm not sure what your talking about could you elaborate? Ok I put this folder in my GAME folder after renaming it to RECOVERY. I then put the 1.5 firmware in there after renaming it to UPDATE. Then I put the new RECOVERY folder in my GAME folder and ran it. I got a black screen and nothing happened. So then I took the eboot from the old recovery folder (from 3.02 OE) and replaced it with the eboot that came with this downgrader. This time after running it it acted like it was going to work but then after I clicked X to accept the license it just gave me errors the whole time SO it didn't work. Lastly I then took the whole old RECOVERY folder and put THIS eboot that came with this file in there and I just got a black screen. SOMEONE HELP ME PLEASE I DON'T WANT TO DO PANDORA BECAUSE IT'LL TAKE ME AT LEAST A COUPLE DAYS TO GET ANOTHER PSP TO DO THE PROCEDURE. Please to whoever coded this project PLEASE make it runable through the recovery menu PLEASE I want my PSP back. Anyone else here have any ideas of how to get my PSP working again????

I switched back only because the kernel 1.50 takes a lot of time to develop. Even more when I know that D_A wants to unbrick first some customized PSPs.

He was so tough with all these noobs who couldn't wait for 3.71M33... But when they break their toys with some dumb customizing, they still must be served first? I don't get the point.

I always followed the updates of the custom firmwares, but here, it is the first time I switched to an anterior custom firmware...

use pandoras battery to recover

SWEET! Finally, a downgrader! I'm so tired of crappy 3.71 M33.
Thanks, Samhain! Though I haven't actually tried this downgrader yet...

Please anyone know how to get this to work through recovery menu, I'm bricked so please someone help me out. I can do Pandora but it will take me some time to get another homebrew PSP to get it to work. Question though guys, when I do the Pandora procedure will I have to delete the stuff off it or can I just make it a magic stick with my stuff on it and then just delete the Pandora stuff manually when I'm done?

Works perfectly...
