Well, this may be reason enough for me to dust off the old E3 Flasher… Looks like E3 are working on some great new stuff. Including ability to dual boot 4.21 and CFW. Sounds like the best of both worlds to me =)
1: E3 Flasher downgrade and dual boot 4.21 OFW successfully . We also successfully dual boot DEX3.55-CEX3.55 . We are studying other dual boot way like DEX4.2-CEX4.21, DEX4.2-CEX3.55 which can help E3 flasher user enjoy more function .
2: We are developing one key switch function for E3 flasher user. User convert DEX to CEX and CEX to DEX very easy ,just like our one key downgrade way.
We will release it free for E3 flasher user when complete.
3: We will release a great news for all PS3 user in next few days, and also with lots of free new game EBOOT .
