    how to flash?
    1. Unlock bootloader with mtkclient
    2. Extract the 7zip file
    3. Flash with SP Flash Tool
    Important Note: You must to flash all the ROM. If consultance only super + userdata or any other part, it will not work. But, because it should flash all the ROM - but, it locks the bootloader ...
    4. Re unlock bootloader with mtkclient
    5. flash empaty vbmeta
    Known Bugs:
    1. Most of functions need to use with touch screen
    (You can install qinpad to type with hardware keys)
    2. System is read-only.
    I packed the super.img as read-write, but it did not work
    3. No access to partition / DATA by Twrp
    4. Backlight always on the keys (thanks to gaugga from 4pda)
    5. can't get files via Bluetooth It works. Sorry for the eror
    6. can't use Bluetooth headphones
    7. can't use headphones (to patch headphons
    Phh settings > Misc > Use alternate way to detect headsets
    and reboot. thanks to zerovoid and il.mikha98 from 4pda)

    f21s Pro is F21 Pro. it is the same thing.
    TWRP brought in 4PDA (Thankful to @ Hagai that brought it in Mitamchim top - the Israeli forum). flash it as boot_a.
    What is LOS18.1-QJIN-F21PRO? This LOS for 32GB from 4PDA? It is based on my ROM.
    You can not lock bootloader After Flashing ROM
    Light in the keys? It's a well-known bug (number 4)
    I now work on repairs, for example better support in hardware keypad.

    Is there any new update?
    The system is fairly stable, however the constant use of the keypad light depletes the battery quickly.
