@xiaobai112220 ported CM13 onto Redmi 4 Prime (625 ONLY)
Here is the original thread (in Chinese)
I've downloaded ROM from the Chinese site and re-uploaded to Google Drive for faster download.
NOTE: BEFORE flashing this ROM you need to unlock the bootloader and flash TWRP recovery made by Cofface
No one will be responsible for any damage it may occur your device and all credit goes to @xiaobai112220 and @cofface
