After months of hibernation, ive decided to revive my PSP. I last got stuck on 5.03 ChickHEN because for some reason i wasnt able to upgrade to 5.03 Prometheus or 5.50GEN D3. Somehow the flashing ALWAYS fail to work. I see there are some newer stuff floating around and was wondering what can I do now. If im not mistaken, 6.60ME-1.8 is a good one to have now? And how do i go about doing that? The readme's can be quite misleading at times.
