Now we have a full-featured 2.8 inch Android 11 smartphone in the format of a classic push-button phone released, having a touchscreen, GPS, BT5.0, IR remote control, dual-band Wi-Fi, two cameras, and all this with MTK A22 chipset. Obviously, QIN F21 Pro is the best in its class.
Unfortunately, QIN F21 Pro is positioned by the manufacturer as a phone for students, hence they closed (and keep closing in the new versions of the firmware!) loopholes and ways to install own third-party software, so there is no standard ability to install any apk locally or through adb, and in the native Chinese market there are only educational programs for China.
The only way to install your own software is the APK renaming and its substitution via PC at the moment when it is being downloaded by the official App Market.
So, guys, any ideas of how to make this phone unchained? It has big potential indeed, so having Google Services would be great, but the bootloader is locked, the FW is signed, MTK flashing tool refuses to flash unsigned paritions.

You can upload the firmware, if you do not have a sucker with uni android tool software

I wish i had full firmware dump available. Unfortunately, just the OTA update.zip

---

Can you upload the system folder?
You can read the firmware from the device with uni android tool!

I wonder, I've read that this device is rootable (there seems to be some guides on chinese forums about this) I just couldn't find any info regarding if it has a unlocked bootloader? Would LineageOS be possible on this? Global version is coming later this year, according to this video.

Ive ordered 2 cracked Chinese units with the mtk6761 with unlocked bootloader + root + playstore.
The rumored Global version will be using the Unisoc T310 soc with its bootloader cannot be unlocked and very secured based on 2 years old phones running it

Iv such unit, rooted, open for install, and with full gplay functionality, but its hard and long process for each device seperatly.
Iv tried a few GSI's, without success tho.

Unlocking unisoc bootloader was always a problem because you Need the rsa4096 private key, and generate a unique signature.bin for each device by its own token.

when it comes ill try to backup the firmware making a scatterfile via box so it could be flash using mtk flashtool. maybe you could try that. theres also lots of turtorials how to backup MTK firmware and create a scatterfile with that if the device can boot to preloader mode
cool! does contacts syncs properly? does it has a custom TWRP already? can it boot recovery via adb or other root advanced reboot app?

Do you have full firmware? Can you enter factory flash mode? There are many tools on the internet how to bypass mtk soc securities for dumping and flashing full firmware. Its funny Chinese not sharing the proceedure how to do it when it will help a lot to a Chinese company to sell their phones. I talked to the seller, and he/she said the technician wont teach them how to globalize the phone. They want to send them EVERY UNIT asking money just to remove the phone's Google restrictions. What a greedy way of thinking. Xda should bann those kind of people here .
The phone with google services could kill all past and future kai OS devices. The world deservers that upgrade to every over priced kai OS dumb phones to become not so dumb.

You need to learn to respect peoples wishes , no one ows you nothing , for start.
Because of the colture of over sharing , you got used that everyone will do the job for you.
do you agree that i can choose either to share or not , something i worked a big amount of time on? good.
now for the process , first unlock BL (there is a free solution mtkClient on github), then disable vb meta's signatures ( google that as well ), after that , you need to edit the super.img manualy ( search for super.img's tools , im sure youll find a few ) for removing the restrictions , because of android 11 copy.past restrictions within the device.

NOT A DUMB PHONE ANYMORE!
The portability, stealth ability, and simplicity of a dumbphone + all the apps of a smartphone with 4/64 max variants. THE BEST OF BOTH WORLDS!
It came with bootloader unlocked, with magisk and with playstore but need to tweak a bit to fix the crappy T9 input and store certification which is not a big deal.
get it here, I vouched this store have it. BUY HERE

yes you are right but the foundation of knowledge how you learn to do that stuffs might be a collective contribution from the open free community just like this site. Did you write the program to unlocked it? Did you spent countless hours coding and debugging for the soulution? but yeah you have your own reasons and i will always respect and understand that. We all have our differences on opinions, values, ways, and traditions on how to do stuffs.
People buy the phone and what if the phone suddenlly crashed? the seller/company might not release aftermarket technical support for the phone leaving owners in the dark and potentially waste their money without a means to restoring it back to a working state.
thank you very much for the process.
