Hi all.
Finally managed to update my firmware to JB this morning. My phone version (as displayed when pressing *#1234#) is as below:
AP : I9300XXEMA2
CP : I9300DXELK1
CSC : I9300OLBEMA1
Actually during the update (I was using ODIN), it Failed during the first attempt. Not sure what to do I disconnected the phone, entered download mode again and tried flashing again. Luckily it worked

My question is, would there be any issues due to the initial update failure? Do I need to Reset my phone back to Factory Setting? If I reset back to Factory Setting, will it keep the JB firmware or will it reset back to the original firmware when I bought the phone (ICS 4.0.4 I think)?
It is recommended to reset to prevent any fc.factory reset will wipe u data only, won't wipe away ur rom version. No worry.
Recommended way is: be4 flash/upgrade, wipe cache, dalvik and also factory reset. Once flash/upgrade, reset again. This is what normally I do to ensure no fc or error.
