Hello, i'm new here. and i really need help for fixing my devices.

I have 3 xperia's with the same conditions, C2105 - C1605 - D2302, but i want to fix my D2302 first

What i did before ? Porting ROM , including boot.img == the result is FAILED
and now, my d2302 is :
1. Dead
2. No flashmode & fastboot (flashtool and fusion box SELG)
3. No vibrate
4. No charging
5. Already disassembly

• If i connect my M2 to charger or PC, red LED is on for a few minutes and then gone. Nothing more.
• SOMC Flash device detected in device manager.
   

1. What should i do?
2. I dont know where is the Test Point, if i try to connect every single golden pin with metal shield, its safe or not?
3. Can i repair my M2 using fusion box SELG?

Sorry for my bad English

Thank you thank you very much
