Please friends, A "Galaxy S3" He

[trickslk]

I know this is a marketing forum, but please forgive me and advice me if you can,



I recently brought a tmobile unlocked, Samsung galaxy s3, T999.

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.



thanks
