tried to update to JB, but theres an error while rebooting. do i have to unroot to upgrade to JB? (and if so, how?) or its not necessary? sorry, n00b question...

cant remember exactly what error though as i was a bit occupied by then and for now, my net is a bit spotty have to try it again later when connection got stable... it was through OTA and download was completed. while it was on auto-reboot, i think it stuck up till 28% or so, maybe? (cant remember) when i checked, its still ICS.

Planning to get to JB, so using the OTA option.

Downloaded fine. Went to start the install process, everything looking good.

Then about halfway through the progress bar where the little green android is laying down with its hood open, I get a red exclamation mark. And everything stops.

Restarted and everything is fine, but still in 4.0.4.

What went wrong actually?

not the first time ive had it. i think its been three to four times now..

ive downloaded it in way faster net connection before and the problem persists. as for this latest attempt though, yea, its rather crappy broadband, admittedly.

what options do i have then? upgrade firmware via kies stuck at 99% download

which source file do you mean? the downloaded OTA? is that even possible?

should i do factory reset and retry OTA? or sammobile is the only option left for me?

would they mind if its rooted? or have to unroot it first and do backup of everything?
