HELP: downgrade to 1.50 when PSP already has CFW

[andwan0]

Am wondering whether it's possible to install 1.50 FW via an "already" soft-modded PSP with CFW 5.01, etc.? A lot of the downgrade tutorials assume the PSP doesn't have CFW and makes the user go through pandora battery steps, etc. Surely with CFW we can run some downgrader program without needing the Lumines hack, etc.? If this is not possible, then what is the easiest/quickest way to downgrade to 1.50 FW with a CFW PSP? (also, don't ask why I want 1.50... I assume 1.50 FW will have the least amount of memory/RAM used up... and I need as much RAM as possible out of 32MB... just to get Quake 2 running)

There is only a way, (at least, I know only this). To downgrade from a cfw to 1.50 ofw.

This is the first real original pandora. Now with Pandora and despertar cementerio, you can jump directly to a cfw, but don't back to 1.50 or others original firmwares. (Maybe hellcat can do this...I don't remember).

Pratically follow that guide and you can back to 1.50 original firmware!.

That seems like a long and complicated way. I manage to get DC3,4,5,7,8. If possible would like to get DC1 & 2 & 6. It seems DC1-5 all required eboots 1.50 & 3.40 first.. before the jump above 3.40 but before 4.xx. From DC6 (I presume onwards) eboots 1.50 & 3.40 weren't needed. So gathering from this, maybe trick DC1,2,3 into installing 1.50... will try it out...

If I well remember cementerio v1 install directly 3.71M33 no lower cfw or original firmware.

it looks like hellcats recovery flasher can do what you want

from the readme

.......you can flash ANY CFW from 3.71 to 5.00
plus OFW-1.50 on classic PSPs

Thanks ... this looks like what I need.

Just tried it and it fully 100% bricked my fat PSP... so hoping Hellcat will fix his program soon in meantime... will need assistance creating a Pandora...

To recovery from a brick you can use Despertar del Cementerio v8. It will unbrick your psp and will install 5.00M33 V6 custom firmware.

Here the guide. (You need another psp with a cfw installed).

i tried it to confirm your results. yes that option resulted in a brick for my fat psp too

if u have access to another another psp you can try hellcats pandora installer. it creates the magic memstick flawlessly for me but the option to create the pandora battery didn't work so i used hellcats recovery tool to make my battery into a pandora/normal

these programs had my fat psp on 1.50 within an hour
