We think lots of user mis-understand us, here is some clarification.
1: E3 FLASHER LIMITED still provide 11 accessory, include esata station.
2: we design e3 flasher on solder way at first, this way can get dual boot well. But later we change hardware and software design because of adding clip. so finally it's difficult to get dual boot function on e3 flasher clip version.
3: You still can get 3.72 and 3.55 switch with 2 HDD, it need more steps than dual boot, maybe we can call it half dual boot. This way no need any solder. We will release this half dual boot way in few days, you just upgrade e3 flasher limited and get it work.
4: We are working hard to allow e3 flasher limited vesion works really dual boot, but we can't promise now because lots of changes.
5: We upload all neccessory software and manual, you can go here to download and enjoy one key downgrade.
6: New e3 flasher should come out in few month with more fantastic function !
