guys me 2 faced same problem of updating SAMSUNG GALAXY Y through kies at last i found a way how to upgrade frimware using kies.... i used to be on Gingerbread DDKJ1..now im upgraded to new frimware Gingerbread DDLA1 which released on jan 2012
i used face issues like memory card is automaticly ejecting itself with my previous DDKJ1 frimware....vl review soon abt my new frimware
i followed below procedure, it worked for me!!
i had windows 7 ultimate... ( ps:kies wont work on windows xp sp2)
1.installed kies from samsung website
2. now go to control panel > click on "programs" > click on Turn windows feature on & off ".......... a pop up menu appears.... in that menu click on "+" beside .net framework 3.5 tick all inside(windows comunication foundation http activation.... and non http activation)
then press OK of that menu!! ....
wait for few min to complete the task...
(diz procedure is used to activate .net framework 3.5 on windows 7 since windows kies require MS.net framwork 3.5 and above
ps:look at specification of kies )
4. now open kies
5 connect samsung galaxy y with usb cable..
6 wait few mins... it will connect!!
7.if any new update releases a pop will come about "new frimware available".... click on upgrade...
8. do not touch screen or vol button and home button until the upgrade finishesss(dont even move mouse(usb) during diz step i found kies will disconnect ....
9.ul see downloading status of frimware...etc... after finishing downloading ul c phone changes into download mode...after finishing update ur phone restarts automaticly
10. ul c sone updating commands on screen.....etc.. after that phone starts normally...check the new frimware version on settings > about phone...
happy upgradingggg!! :-)
