Galaxy s3

[Guest amir.eng2007]

Hi

The S3 slave was turned off and turned on after turning on Android's Android. I'm connecting to the computer so I can not connect to the RAM. I'm upgrading with jtag cable. I do not know if I can get a new RAM. Now is it a while that it does not come with Android, and when I charge it, the shape of the checker goes down and it will not turn on, nor will it come in any other way, and I have to turn on the battery to turn off the screen. Thank you, where is the problem?

Thanks
