Downgrade 3.71M33 to 1.50 without pandora

[pt9087]

Hey is there anyone here that has experience with the Pandora procedure? I have a working 3.52 M33 PSP and my bricked 3.71 M33 PSP and I tried twice using the Pandora steps and something just wasn't working each time. I would appreciate it if someone could help me and maybe walk me through it since obviously I couldn't get it to work last night. I meet all the requirements so PLEASE anyone that can find it in they're hearts please PM me or talk to me on here.

If it did not boot then your ipl is not bootable.

If you live in england i could unbrick it for you.

For those who dont feel like waiting for your battery to charge to 75%, hold L + Triangle from gameboot till the disclaimer

I do not recommend if the XMB reads your battery as 20% or lower. (even though the entire process takes about 0.5% to 2%, depending on your screen brightness)

No I don't live in england, no there was this one step that wouldn't go right so I think that was the problem. I'm currently getting help from Darth Paul so.

Rename Original FW 1.50 file to UPDATE.PBP and copy it to PSP\GAME\UPDATE folder.

[CaptainMorgan4]

They have firmware downloads at psp-hacks.com and I'm sure if you searched you could find one on here some where.

*!!PLEASE someone report this bug!!*
The 4gb Sandisk Ruby Red and quite possibly all the 4gb memory sticks (need further testing) are not compatable to be made into Magic Pandora Memory Sticks.

I can confirm that 4g memory sticks will NOT work!(using pandora installer) When you try to re-partition and format the stick it goes right into the set-up of 1.5 firm and then wants to set the msipl file, when it does and exits it says there is no memory stick - this is wrong, it should tell you to re-boot the psp at the end of format -- 1g and under (as long as it's a pro stick) WILL work.
