One more thing: I noticed that formatting the Tecno D5 before flashing using the 'Format all flash except bootloader' option caused it to become totally dead!
DO NOT EVER CHOOSE "FORMAT ALL FLASH EXCEPT BOOTLOADER" OPTION FOR TECNO D5!!!
I was also able to revive it by connecting the GND and KCOLO, then choosing the 'Format All Flash' option. I make no mistake. I really experimented with it!!!
This way, you can even flash the ROM without the soldered cable because the PC will detect it, that's after choosing the 'Format all Flash' option when the two gold plates on the board are joined.
