Arr… I cannot wait for JDMS v1.7 Ultimate which should support A2SD+ and in Zip ROM format. So I took the beta unsupported build Zip version to play. It is exactly the same as previous build which is based on Ultimate Droid 2.5, Android 2.2.1 and using Hastarin 8.6 Kernel. But this one is using ClockworkMod Recovery method. I can backup and restore it now. Yeah!!!
