Hello! first post on this site So, I just got a PSP from a friend. It's in 3.80 m33, and he gave me the permission to update to 5.00 m33-4. I went to dark alex's site, downloaded everything i needed (the 500m33_4 folder and 500.pbp). I prepared everything, and i searched on google if they were any special things i first needed to do. I found two things, but i'm not sure. -Have at least 75% battery, the best is 100% -Go to recovery mode, enable 1.50 or something like that. I've done the battery thing, but I never heard before of the recovery thingy :/ Can you help me plz? and if I forgot other small details, please let me know Thanks!
