Well i had the Blazblue (1st) disc in, and i checked all of my games and the only one that works is Tales of Vesperia As long as i have that and Graces F i won't go insane. So... i'll just use the downgrade that rogero made to go to 3.55 and remove disc when upgrading and I'll see what happens. On a side note, i really heard no kind of warning about this disc/upgrade thing, and i don't know if it's publicly known, but whatever.
I did use the rogero downgrader, what happend was I installed the downgrader thru recovery mode then went to xmb update and it recognized the 4.21-3.55 downgrader, but when it started the upgrade it gave me the 8002f157 error. it also says its on 4,21 now in system info where before it said 4.25.so i tried the 3.55 kmeaw hoping i was on the 3.7 rogero (4.25spoof showing in system info) which would allow me to downgrade, and it did in recovery mode it allowed 3.55 kmeaw.
Rogero why you gotta mess with my halloween thinking ill get 4.21 easy peasy. anyway at least i may have helped some people who get stuck on 4.21 with no flasher, the downgrader did work with a couple reboots to recovery mode (4.55-3.55 downgrader, then 3.7 rogero in recovery mode to error code then 3.55 kmeaw in recovery mode, I did do a couple system restores in there also just cuz i was trying to get to the bottom of this ) and a fat doobie to calm nerves also advisable.
OMG, i'm so confused at this point, and i'm not sure what to do. I wanna say, Use 421 downgrade to Rogero 3.55, then install 3.55 OFW, then Rogero 4.21 WITHOUT A PS3 DISC, but at this point i don't even know anymore.
I have run into the same issue as Axlmegaman. I updated to the original Rogero 4.25/4.21 from KMEAW 3.55 on release.
I ran the 4.21 to 3.55 Downgrader, then attempted to run the Rogero 3.55 PUP. I got the 4.40 error. No disc in the drive. No active internet connection.
It seems that multiMAN will still run games signed for 3.55, but nothing that is not without giving out an error. System shows me at 4.21, multiMAN shows me at 3.55. Anybody have more information regarding this?
