I downgraded back to 1.5 from 2.6. I used X-Flash to take the crappy backgrounds off and put the original ones on. Also to put my own font back on it instead of the crappy one. I've been able to get Devhook and "unmentionables" to run perfectly. My question is if it's true that 2.6 files are left over in flash. At first I didn't think it was possible because I thought that would brick the PSP, but then I did my own dump of the firmware to help my friend downgrade and it came out to 15mb. The dump I used was 9mb. Where did that extra 6mb come from?
