I've been searching online for a way to either downgrade to 1.5 in order to install custom firmwares, etc. But all my old bookmarks and most of the links in the "Rules sections" are dead. I haven't touched the PSP hacking community in a very long time. Back then I needed to create a Pandora battery to downgrade and do what ever with my PSP (which I haven't done). The devhook site is offline, most links are dead. Even using the archive.org to restore some information, all the software download links are dead. What I want: Download the newer games and play them (as well as emulators or homebrews). Can I? Install a custom firmware such as 6.60 PRO-C fix 3 or any other versions directly from my 3.11 version with a broken UMD drive? My PSP info: PSP-1001 v3.11 (official if I remember correctly, originally a 1.5 firmware) UMD not working on this PSP! So the Lumines UMD based hacks won't work. I also have another PSP which I could also hack but rather not take the chance to brick it: PSP-1001 v3.40 OE-A (I think it was hacked when bought online, not sure if I officially upgraded it after) Do I need: To go through the Pandora + Magic Memory Stick (thankfully the Pandora battery seems to be pretty easy now) or Install official firmware 6.20 (isn't getting stuck in higher versions a bad thing especially if you ever want to go back to version 1.5) and http://wololo.net/installing-pro-cfw-on-a-psp-1000-psp-phat/ or Anything better?
