@Ransiri

You can repair this via ATF 12.00 (Which you can get from AUTO-UPDATE Server or downloader full installer here:

ATF_v12.00_Full_Installer.rar


As of now, only SAMSUNG EMMC CHIP is supported.
So Check your Phone if inside is a Samsung eMMC Chip.

The EMMC Chip is the one with the YELLOW BOX in the TP Pictures.
If your eMMC is SK Hynix, then there is nothing we can do for now.

To Repair:

You need to open phone and Connect 4 wires to eMMC Connection.

Pinout is here:
C:\AdvanceBox Turbo Flasher\Nokia\Lumia\TP_PIX\520_TP_HIRES.jpg


Then After you solder the Wires correctly, do this:






After you do this, check if phone still need to be flashed via USB... Otherwise, WP BIT IS ALREADY REMOVED.
