I have an old PSP (not the slim version) with firmware 3.73. I read the readme file and placed the MS_Root_371 in the PSP main folder. I waited one minute, unplugged the USB, restarted the PSP while holding R but nothing happened. I tried this again, nothing, then I only copied the folder "seplugins" into the PSP ... still nothing .. is there something I am doing wrong ... I checked the main site and it said something about Dark Alex ... do I need to download that. Any help would be awesome!
--EDIT--
Now I have version 3.80. Was I not supposed to upgrade
