my phone info :
Build info: Mon Aug 29 14:04:52 KST 2011
am so beginner in phone flashing stuffs
i've been trying to check always to see if i can upgrade the firmware by the phone or by Kies
trying update software on Phone = ( Unable to connect )
trying to check for new firmware on Kies = ( Kies doesn't support your device )
i did so many researches and i found a post here talking about that code that check the original CSC code *#272*[Device IMEI code with no brackets]#
i did checked mine and i found out that i got :
Sales Code: XSG
out of carious ...
i select EGY and i pressed install i had wiped data and phone reset which i got no problem with that since i wanna learn on my own phone
and after the phone reboot i had no problems with it at all it was doing well and great.
after that i opened Kies and i saw this ...
My questions is :
1- was the changing of the Sales Code wrong idea ?
1- should i proceed this update after i changed the Sales Code to EGY ?
2- is this is the update of ICS ?
3- what if i fail with the upgrade is there is anyway to go back to my original ROM?
4- any harm will cause for the phone ?
Any answer would be Appreciated ,,,
Thank you in Advance
