TUTORIAL UPDATE!

MY DEVICE IS 4/64 with unlocked bootloader

Unofficial Qin F21 Pro (MTK chipset) firmware, version 1.1.1 multilanguage.

Thanks to @redsat, @gaguga and the whole 4pda community.

Install at your own risk and responsibility.

For testing purposes only, will be updated or changed if necessary.

Use SP flash tool for flashing, bootloader should be unlocked on the phone (via @mlgmxyysd tool or Ubuntu boot image). Having the full own ROM dump is highly recommended in advance.

Changes:

-Removed chinese applications

-Decrypted data partition

-APK installer with no restrictions

-System partitions are writable

TWRP recovery 3.6.0_11-0 is added

(In TWRP the phone memory is accessible via path: /data/media/0)

WARNING: FLASHING THE FIRMWARE WILL WIPE EVERYTHING! I SUGGEST BACKUP IMPORTANT FILES BEFORE DOING THIS. I WILL NOT BE HELD RESPONSIBLE IF YOUR PHONE DONT BOOT, SOFT/HARD BRICKED! THIS TUTORIAL IS TO DO AT YOUR OWN RISK!

ALL FILES REQUIRED FOR WINDOWS https://www.mediafire.com/file/tl8hv77gl0vo6sd/qin_f21_pro_mtk.zip/file

download and extract zip

extract "F21PRO_1.1.1 (2).zip" (the firmware)

extract "SP_Flash_Tool_V5.zip" (flash tool)

install drivers

open "flash_tool.exe"

select scatter file from the firmware folder

click download

turn phone off

hold back button then plug usb cable to pc. It should start flashing

after try turn on phone (1st boot takes a while)

Congrats! You now have chinese free apps firmware with TWRP Installed

If it wont boot "DEVICE ENCRYPTED", just go to TWRP and FORMAT DATA then reboot (it should boot to system now)

transfer "boot_2.img" phone or transfer it to a USB Flashdrive (more easier to locate) (FOR 3/32 VARIANTS TRY TO USE THIS BOOT IMAGE BOOT.IMG 3/32)

boot to TWRP once again

go to device path /data/media/0 or USB storage path using OTG

FLASH IMAGE "boot_2.img" to boot partition to fix the device twrp path to /sdcard (IMPORTANT! boot is an IMAGE FILE not ZIP FILE. by default, TWRP is set to check for zip file and will n0t se IMAGE FILES in the directories. YOU NEED TO TAP THE INSTAL IMAGE BUTTON so image files will appear)

reboot and proceed to installing ROOT and Google services

HOW TO BOOT TWRP:

* + heart button (upper left) + power on. once douqin logo appears press up button + power on immediately. TWRP first boot is in Russian language. just change it to english change twrp language

HOW TO ROOT + GAPPS with playstore certified + fix keypad annoying issue

transfer all the app APK from the "APK" folder youve download

install everything (QinPad be a more stable keypad input)

open gboard and enabled both gboard and QinPad (this should give you a quick switch of input in the notification bar everytime you will type something)

open MAgisk app and update the apps to 22.1. phone reboots (DO NOT UPDATE TO VERSION 24.3)

Open magisk again then Install Magisk > Select a patch file > choose "boot_2.img" in your directory (path where you transfer it)

transfer "open_gapps-arm64-11.0-pico-20211217.zip" to device

boot to TWRP

FLASH IMAGE "boot_2.img_patch" IN THE BOOT PARTITION. then reboot. should be found in download path in TWRP

go TWRP again and flash "open_gapps-arm64-11.0-pico-20211217.zip"

reboot > SYSTEM

you will see playstore. you will have an annoying message "device isnt playstore certified" just ignore it

open MAGISK app go to settings and enable MAGISK HIDE, search module and install "Busybox for NDK" then reboot

open MAGISK app, search module and install "MagiskHide Props Config" then reboot

open Terminal emulator app

type "su" enter (grant permission)

type "props" enter

type "1" enter

type "F" enter

type "30" enter

type "25" enter

type "2" enter

type "y" enter

type "y" enter (phone reboots)

after reboot wait gapps to update (around 5-10 mins) then sign in to playstore

you've now enter Playstore

go to playstore settings > about > click update playstore

wait for it to update the version and keep checking in playstore settings > about > IF DEVICE IS CERTIFIED

If the updated playstore still said " DEVICE IS NOT CERTIFIED", proceed to manual

install device id apps from playstore and copy your GSF ID

register it manually here > https://www.google.com/android/uncertified/?pli=1

go settings ~ apps and look for playstore and play services and clear data. reboot phone and Playstore should be certified!

Congats! your phone now is rooted with twrp, no more chinese apps, and with fully working google services. I suggest perform a TWRP backup and store it somewhere safe for future use.

HOW TO FIX NO/DELAYED INSTALLED APPS NOTIFICATIONS

Thanks for JawadEly for the info, it works!

1. Install all your apps

2. Install terminal emulator app and system app remover app from playstore (this will give you the apk path you want to systemize)

3. open magisk, search and intall "APP SYSTEMIZER" module then reboot.

4. open terminal emulator app

6. type "su" and grant the permission

7. type "systemize"

8. You need to set Selinux = TRUE by choosing "s"

9. once its set to TRUE, you can now systemize any app provided you know the apk path of the apps installed.

10. enter "3", here is where you put the apk path of the app you want to systemize

11. to get the apk path of installed app open the "system app remover" app you installed.

12. go to user apps and LONG PRESS an app you wish to systemize.

13. copy the apk path then go to terminal emulator and paste it. Type "1" to confirm.

14. Go to settings > apps list > clear storage of that app you transfer as system app

15. done! just repeat the proceedure for each app you wish to fix the notifications.

BEWARE! Be careful using system app remover. Don't uninstall system apps required for the android system. You might end up in a bootloop. This app is also used to remove bloatwares of OEM firmwares.
