How to repair via JTAG???

Step 1: Download ATF JTAG Software Base Installer Here:

Step 2: Update ATF Software to 1.04 (So that your are using latest version) Download

Step 3: Download  Additional Big Boot Files here: (Only Needed if phone cannot flash after initial JTAG repair)

For Basic JTAG Repair. Run ATF JTAG Software then click "SELECT PHONE". Then

choose proper AFP file for proper phone model RM-XXX.

After file loads, it will show you test points where you need to solder wires. After

soldering wires 100% ok, then click "RESTORE BOOT".

Plan B: Repair Boot via eMMC TP.

This is another method of repairing boot which requires less wires to solder and

does not need ATF JTAG Activation...

TP Pictures for where to solder can be found here:
