    Nope, it's not possible. At most if i am not wrong, the lowest u can downgrade to is only 3.71 with the pandora battery.
    MAY GOD BLESS YOU.

    well, thats wrong. you can flash install 1.5 ofw from any firmware on 1k using hellcats.
    follow the steps in my guide section 5 to do so.

    is that even possible to directly dive down to 1.5 from 6.60? if it doesn't work y0. you would wanna try to downgrade your psp first using my "PSP 6.XX downgraderv4" guide(which is on my sig), then flash it down to 1.5

    yeah. just use my downgrader guide yo!! using psp 6.xx downgraderv4, you can dive straight from 6.60 to 5.50. yes, i've tested and tried that. so no worries asking if it's gonna brick or not as long as the battery doesn't pop off the psp, youre good

    both google search :
    hellcat's recovery flasher
    sony ofw 1.50

    put the 150.pbp inside the RECOVERY folder, which you can obtain from the extracted file of hellcat's rar file. then, that recovery will be placed in file directory ms0:/PSP/GAME and will be run in the psp's xmb. run the app, select the target firmware (which in your place is 1.50), then select to format mms. (it will not legitly format your ms, the maker of the homebrew seems to be smoking socks the moment he made it, so he just put whatever thoughts in the homebrew.) get back and tell me if it's succesffuly flashed back. else gonna have to try pandora + mms combo .

    tried that one method earlier and got the error msg like the game could not be started..

    right now I'm trying to go to 5.03---> use chickhen r2 then install 5.00 M33

    if everything works smoothly, I'm gonna try to make a pandora mms and batt

    so.. fingers crossed...

    btw, damn... i missed so much after i sold my psp a year ago.. i used to have 5.00 M333 and a working MMS ready to use..
