I didnt do any odin or reverting back to DI18 as I already was on stock DI18; Put GPS back on Hot Start after getting lock on cold start; Put full MDN text dump (kindly be on appropriate data plan for mdn as username) and then did the OTA (notification for which I was getting since many days)...
EC05 rom seems very stable till now... evdo working
- got Unable to update Firmware error on first boot (as my data was off at that time and I was on Wifi); Firmware update as such isnt needed and I didnt see that message again after reboot and battery pull
- gps stable with very fast lock
- on new Launcher Pro Plus
- some notification tones got mixed up; set default notification back to Android System and it started working
- Had to reset launcher pro as default home
- Updated all apps from market; New Home Switcher was needed; New Launcher Pro got manually updated; New Samsung Desk Home got updated for froyo version
- All data backup, sms, apps etc. remained as it is and I didnt have to re-install anything
- Had to reset my Alarms (lolz... acchha hai maine dhyan kar liya nahi to kal ka tennis miss ho jaata)
Conclusion: Instability on EC05 was a result of RelMobileWorld username and pw and nothing else... EC05 is absolutely stable and I would suggest all to upgrade...
