Unlocked Honor 7x : See this [But don't flash twrp from anywhere else before backing up your device. Use twrpimgmount_ramdisk for backing it up first.]
TWRP Complete Backup
TWRP Img mount not tested yet
Flash twrpimgmount_ramdisk.img through fastboot
fastboot flash recovery_ramdisk twrpimgmount_ramdisk.img
Backup/restore and flash image functions are tested for system/vendor/product/version/cust/oeminfo/recovery/recovery2/boot rest of them are not tested by me but should work.
Note: It is suggested to make a complete backup in memory card before rooting your Honor 7x.
After backing up, flash TWRP Complete Backup Ramdisk
