I tryed multiple time to flash my phone (original ROM) with Odin and other software. Most of the times the connection cannot be established. I have tries with different computers and different cables, including the original one.
I think the Micro USB connector in my phone is broken. I can still recharge but data transfer is not possible.
I have an SD card where i can put a ROM in order to update my phone. But if i'm correct that isn't possible if I don't have ClockworkMod Recovery.
So finaly my question: Is it possible to root and/or flash (CyanogenMod or other) my S3 without a cable?
If i Try to install ClockworkMod Recovery via Rom Manager I get the following error : An error occured while flashing your recovery.
Have a nice day!
