My 4c Cannot Flash In 3rd-party Roms

[winginmars]

I unlocked my bootloader and used
fastboot oem device-info to confirm that I unlocked
Firstly I flashed in a TWRP Rec
fastboot flash recovery ..../twrp.img
fastboot boot twrp.img
And successfully boot into rec.
Then I tried to install the ROM. After flashing it stuck on the Mi Logo every time.
Tried sideload and "install" by the TWRP but didn't work.

Tried to install XOSP and Slim, both failed. XOSP is based on 7.1.1 and the other was 6.0.1

Do a full wipe ....it should work if the version of TWRP you used is compatible.....

……every time I did a FULL wipe including system, data, etc.
And it didn't work.
I even checked the MD5 of the ROM file, the recovery.Nothing went wrong.WTF.:-(
