1, download hashcode's flash.zip bootloader from the development section
2. If you can get into TWRP then flash zip from there.
if you cannot get into twrp then: extract u-boot.bin file from zip file and use fastboot to flash it:
fastboot flash bootloader u-boot.bin
3. Then download and flash TWRP again using fastboot or KFU. I like to use KFU to install TWRP but it can be install using fastboot:
The code to flash twrp using fastboot is (rename TWRP file as recovery.img):
fastboot flash recovery recovery.img
Also: before flash using fastboot it is better to make sure it is properly connect by issue:
fastboot getvar product
If it return some number then it mean the device is connected properly.
