I tried to upgrade firmware with samsung keis, but it stucked at 0.
Then I tried, Emergency Firmware Recovery, it also got stuck.
I rooted it and applied a custom rom, CyanogenMod
Then i wasnt able to turn on wifi, SIM not detected, etc.
Then I wiped all data, reset the phone.
Now it doesnt goto the home screen, stuck at loading(with that google 4 colord dots).
I can ONLY access, Recovery Mode and DOwnload mode properly.
Even my laptop doesnt detect the phone. Micro SD card also not detected by phone.
As you can see, i acted like a total idiotic, and also I know nothing about android. I was doing those by googling. and watching tutes.
If you can advice me....would be a great help.
