My goal: install a 5.50 Gen-D from a PSP1000 (TA-0082) with OFW 3.11
A friend of mine gave me 2 x PSP1000 (nice friend), the UMD slot shows IC1003 (so I believe those mobo are TA-0082), the firmware on both are 3.11
I have no Pandora battery (I'm thinking modding one of my 2 battery)
I have no Magic Memory Stick (MMS)
I'm over 30, so do not know anyone with a modded PSP
I have read a lot of forum, maybe too many, and I'm now lost. And every forum I read about a OFW3.11 on a TA-0082 are pretty old.
So far I was thinking to upgrade the official way to the OFW 6.20, but I'm not sure if I can downgrade later to a 5.50GEN-D since my mobo is a TA-0082, and of course how ???
The other route seems to be to downgrade to 1.50 with a Limunes (games) - //forums.noobz.eu/downgrader-support/3-11-upgrader-downgrader-guide-instructions/0/
and then do many upgrade up to 5.50GEN-D
But this is a very old post, and I'm not sure it is the easiest route
Thank you for your help
