About a half year ago I had to deal with the same problem on my 1004. I remember I tried some kind of downgrader to went back to 1.50 and then update do 6.60. Ended up with a brick. ¯ (ツ)/¯ Hopefully it was the PSP Fat, so I made a pandora battery to flash the new system via recovery mode (had to order new battery though, because I broke the plastic case, if I knew I'll end up with a brick I'd make one using a software method). Weeks after I found this on the web: I haven't used that but hackinformer is a trusted site, so you can try.
