NO! only a HW Flasher can be used at the moment to switch between firmwares (OFW & CFW). You can however still login to PSN/SEN on REX 4.21.1 and play all the latest games.
yes i mean with a e3, because it puts syscon to 9.99. so is it possible with a hardware flasher?
also what is the risk of being banned on 4.21.1 and how can i avoid them?
Great news I like rebug,I use 3.55.2 is the best for me, until now Rogero 4.30 is great with all updates and PSN. Everybody is waiting more from rebug, a CFW to install over a UPGRADED OFW coz are the best team, any way thanks REBUG...
Thats one reason why I'm not updating atm. I have mine set at 9.99 so it never asks for an update and all the games i play work in 3.55 as I patch them all.
I've also edited the XMB and not sure if you can do that in 4.xx CFW. I've removed all the online things and moved homebrew around. The PSN tab is now the MultiMan tab so when you boot up the console it goes straight to MultiMan instead of WHATS NEW.
