Hello Masters !!!!

I have Samsung S5603 (3G) I tried to install a firmware on it using multiloader, in first time it worked with many firmware of S5600..

When I tried with a S7070 firmware, the multiloader has reset my boot and my computer stopped detecting my mobile phone.

now I have a black screen when I try to power on my phone, and is not detectable on the computer neither in an NSpro box or multiloader..

Reading in forums and forums, I found that the solution is just using JTAG, can someone teach me how to use it ?? and if you have any solution please give me !!! am in a big panic !!!!


Thanks Bros
