It does helps. It looks like you doing fine. Would you mind answering...

1. What color of the box it comes with?

2. Once you receive it does phone works normal?

3. Phone's signal working fine?

4. Is it already unlocked boot loader? Or you unlocked it?

coz most unit from the blue box batch have a missing imei issue. We dont know if your no SLOT A (maybe corrupt) is an eMMC hardware issue that you need to open a dispute from seller.

If its one of the unit that comes with NO IMEI, maybe the seller's techs messed up the EMMC radio partition attempting to unlocked phone's bands and slot a is also messed up. IF thats the case, you could try to flash an official dump firmware, or look for a TWRP backup for your variant and restore that backup to your phone. This should fix eMMC courrupted adresses

And i cant seem to follow what you did. you giving infos a bit skipping on what happened.

at first your problem was on Step 10. I told you to factory reset it.

after 10 there's step 11 and 12

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

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

"IT SHOULD BOOT TO SYSTEM NOW" did it boot? did you checked the simcard for signal, etc?

you need to provide these details and confirmed these so its easy to trace where did you mess up the system.

in TWRP you can try to..

- reboot fastboot

- plug phone to pc

- use minimal adb and fastboot (download it)

- type " fastboot devices " (should give you a serial to confirm connection)

- type " fastboot --set-active=a "

this is how to change phone's current slot to A manually. if the firmware is there, it should boot
[General Topics] Leebrown2709:
it came with blue box

yeah it worked fine, managed to access the apps on the phone.

Phone calls and messages were also fine no issue with signal.

I unlocked it with the unlocking tool.

I bought mine from aliexpress from the qin store.

there is IMEI number on the back of the phone.
[General Topics] Jbazt_katuforzs:
its not a hardware issue then. after flashing > twrp > reset. did it boot?
[General Topics] Leebrown2709:
after download complete, unplug then boot to TWRP then reset factory - error messaged appeared that i showed

Congrats! You now have chinese free apps firmware with TWRP Installed - Am i meant to be able to access the phone and use it as normal then?

If it wont boot "DEVICE ENCRYPTED", just go to TWRP and FORMAT DATA then reboot (it should boot to system now), My phone just took me to duoqin screen then restarted

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), added this file to my phone

boot to TWRP once again - i managed to load twrp

go to device path /data/media/0 or USB storage path using OTG - click on install and navigated to that file

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) Clicked on boot.img and then boot partition the swiped it, it showed that it installed

reboot and proceed to installing ROOT and Google services, when i reboot it just bootloops, so i load twrp to get out of bootloop
[General Topics] Jbazt_katuforzs:
1. after factory reset, you should boot first to confirm the succesful firmware flash

2. yes you should boot it the first time

3-5. you should transfer it when phone is fully working. if the phone cant even go to system and not booting, there's no boot file to replace for your 7 if that make sense. and there's no point on doing the next steps.

now i know where you having problem. because you dont let it boot first just to check if theres a firmware.

theres something wrong how you reset the phone in TWRP after flashing. you keep on deleting the firmware youve just flashed.

1. go to TWRP > WIPE > ADVANCED WIPE > CHECK 4 BOXES > SWIPE TO WIPE > BACK

2. FORMAT DATA > types "yes" > BACK > BACK

3. REBOOT > POWER OFF

4. RE-FLASH IN PC

5. go to TWRP > WIPE > ADVANCED WIPE > CHECK 4 BOXES > SWIPE TO WIPE > BACK > BACK

6. REBOOT > IF IT SAYS "CURRENT SLOT A" > TAP SYSTEM > IT WILL BOOT

7. WAIT IT TO 1ST BOOT. PLS LET IT BOOT TO ATLEAST CONFIRM THAT THERE'S A FIRMWARE

See I have no problem flashing and installing this stock firmware rom. Everything works fine on it, although I cant download aurora store or fdroid because it only lets me use the chinese app store and it also seems to go to Slot B on TWRP. Honestly baffled with this. I have had no problems on other phones but when it has came to this, i have nothing but problems. I might just sell the phone!
[General Topics] Jbazt_katuforzs:
So use that official firmware then. Try to root and and put playstore. You can try to flash an official dump of a 1.05 firmware. For some strange reasons, your firmware is customed to work on SLOT B.

Or you could try to ask someone to upload their TWRP backup of their freshly setup phone running this firmware and restore it to yours via TWRP. And for safety measures, make sure you twrp backup yours 1st esp the boot, system, modem, etc and save it on your pc
[General Topics] Jbazt_katuforzs:
Originally 1st phones came with 1.0.3. no playstore and cant install apps. Then the community figured out a way who to install apps apk manually using a file browser. As firmwares updates comes they are fixing that apk installation. My suggestion is try to find tutorial how to downgrade phone. Read 4pda forum discussions.

But if you said that firmware flashing giving you a success results, i means the firmware is flashed. And you've install TWRP. But it looks like the 2.1.8 firmware kind locked your slot A. That phone is weird
[General Topics] Leebrown2709:
I personally dont want the playstore on device, intend to just use aurora and fdroid. Would be great if someone managed to send me there firmware to see if it worked.

everything works on 2.1.6 but when it asks me to update on the actually phone it does not let me install the 2.1.8 version. I need to try do that through TWRP.

I have been on 4pda but there so much to read through to try find what i am looking for and to understand what to do.
[General Topics] Jbazt_katuforzs:
Yes all ota updates will fail bcoz youve already unlocked the bootloader. I suggest you downgrade to what version you know manual installing apps is working.

Or flash a full dump or an offical firmware but you need to relocked your bootloader for the original fàctory firmware to flash or try to restore the oem recovery. Your phone is different in software and hardware configuration from the batches that can use this tutorial. Im sure that version has already been talked in 4da forum ang probably there's a workaround how to downgrade it or make this firmware work. You could also try to ask in telegram groups coz 4pda is in Russian.

[General Topics] Henry10Sugar:
Hi I used these instructions for a F21 Pro 32GB

Thank very much! it worked.

However I spent 10 hours to get playstore to work

I am a iphone guy, so android and rooting android was new to me.

Several things can be clearer. I will list them here to help others.

Step 4) before step 4 you need to have your wifi password, otherwise you cannot proceed.

also the screen shots found in later pages, showing the differece between "installed" and not "installed" helped alot.

"the apps" should say "the app" (I initially thought that all apk's need patching and wasted a lot of time trying to do it)

Step 5) as I have 32gb I used the BOOT.IMG 3/32 in the initial step 13)

it could be made clear that if this is the case you need to patch use this file thought, not "boot_2.img".

Step 8) it could be made clearer that you are patching a file and the resulting file will be located on the phone.

WARNING: AFTER SEARCING FOR AGES I FOUND THE PATCHED FILE IN A DIFFERENT LOCATION. main "DOWNLOADS" (not /sd...) so the message in Magisk had the wrong location.

14) open Terminal emulator app. Instructions did not work. after "su" there was no "grant" message, it opened up Magisk, and the other actions did nothing.

After many guesses, I tried unhiding Magisk, rebooting, and then 14) worked. I then rebooted, and re-hid Magisk

so the instructions to hide magisk is premature, in my case and caused it to fail.

The above took me 10 hours to realise.

Got there in the end though.

Thank you
[General Topics] Jbazt_katuforzs:
Thanks for sharing how you made it work. Yes, for 3/32 variants, should use the "BOOT 3/32" instead of the boot_2.img (for 4/64) attached in zip download

Hi Some incoming calls are coming up with Chinese text. Also some other places there is Chinese text. I have tried changing the keyboard but no change. I guess it is the default of this android version. Any ideas how to change this?
[General Topics] Henry10Sugar:
Besides for the default language being in Chinese, There is no "assisted dialing" in this ROM, so numbers saved in contact with the prefix, +44 for UK, will not display with the correct contact which comes in to the phone as 07.....
[General Topics] Henry10Sugar:
So 3 things are annoying in this ROM

1) sms messages do not show up on a locked screen

2) chinese text in many labels/badges (and if you don't have the contact saved, you get chinese)

3) no assisted dialing options to recognise incoming and outgoing calls with various prefixes

your device storge is in

to what folder did you copy the img?
[General Topics] Jbazt_katuforzs:
It's included inside the zip file youve download. you should transfer it manually to the phone

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

the boot_2.img will fix phone's storage path to /sdcard
[General Topics] Jbazt_katuforzs:
for some strange reasons, this is a bug of systemizer or the firmware if you uninstall the app youve transfered using systemizer. you need to factory reset the phone to remove the force closing app error.

I have super.bin image file for Qin F22 Pro from the seller , the phone came with stock android firmware and google play + all languages but the buttons (answer call , end call etc..) werent working right , they were not mapped, everything else was working great but i needed a full working keypad (so the phone can be controlled only from it).

The phone came with unlocked bootloader.

After flashing this version of the ROM (with factory UI and google play ,but only CH and EN languages, no bloatware) seems that WiFI stopped working (no driver error or something) and an app keeps crashing time to time in the background, Youtube doesnt work and i cant remove widgets with stock launcher (i replaced with nova launcher) the rest seems to work just fine (buttons are mapped correctly now).

Flashed with: flashboot flash super super.bin

I would like to know if its possible to modify contents in super.bin and reflash (possibly to add and extra language and fix the WiFI and rest of the problems , mainly the WiFI problem)

Anyone wants to give a shot fixing this firmware (if possible, i can upload it somewhere) ? ( i am stuck with it as i didnt backup the old firmware)

came acrossed a new posted screenshot of the phone in 4da. for some strange reasons, the screenshots appears to be on data with carrier aggregation (4G+). Its like phone's modem configuration was supported or allowed to connect to 2 (or more) cell tower 4G signals it could pickup to combine the data speeds. I know this custom firmware was made based on the early firmware of the device and Ive tried enabling that carrier aggregation settings in Engineering mode but always failed (kernel locked?). I know there's like 2-3 versions of the firmware came stock from the factory. Can anyone comfirm that this firmware supports 4G+ (carrier aggregation) as well? or yall not getting the 4G+ too? or its just my simcard (new established network service) not capable of aggregation yet. Because if its not, I want to know whats the version of the firmware that does. The phone's specs sheets doesnt listed it supports carrier aggregation (CA) when advertised. perhaps its one of the updates pushes theyve added or theyve unlocked to improve the firmware bcoz the SOC trully supports carrier aggregation.

Hello everyone, and sorry for the long post.

Is anyone suffering from applications being forced closed?

I am on firmware 2.1.6

I have ordered a 4/64 unlocked with GAPPS from AliExpress, and what I received is reasonably de-Chinesed. But it still has the default Qin Launcher and the essential apps provided by Xiaomi (like dialer, contacts, calendar, ...) which is great as they are tailored for this form factor.

There are few issues here and there, but my biggest problem is app closing in the background... a typical Chinese rom issue for non-whitelisted apps... so it is killing Whatsapp and Teams which are vital to me.

The Question: Can I (and should I) downgrade to this rom based on firmware 1.1.1? and if so, what would I lose?

Alternatively, what can be done to prevent the apps from closing? (I assume my bootloader is already unlocked as Google Pay and banking apps refuse to work).

So many thanks to everyone.
[General Topics] Jbazt_katuforzs:
There's a tutorial on page 1 how to systemize installed apps to fix notification. Transfer the app installed by choosing 1 (to sytem/app) or 2 ( to system/priv-app if app requires sensitive permissions to work)

You need to transfer the app to system so the app's permissions process wont close in tha background fixing its notification.

You could try to flash the firmware here just make a twrp backup first of your rom or a backup of its full flashtool firmware before you proceed. It's based from stocked official OEM just debloated of Chinese pre-installed apps so its basically similar.
[General Topics] ppczouz:
Thank you for the writeup @Jbazt_katuforzs

I did think of the systemizer as a possible solution, I just didn't correlate delay/missing alerts with applications being killed in the background (silly me!!)

Not sure if my phone is rooted, but I will attempt some of the steps on P1 and see where that leads me.

Many thanks

But overall, I'm super happy, all is now humming nicely and I have finally been able to systemize Whatsapp and Teams.

[General Topics] Jbazt_katuforzs:
Dunno what are the changes but if there were, it might be just minor or some bugs fixes. There is! manually unlock the bootloader, manually install the TWRP, then add root and gooogle playstore (optional). Using system app remover can remove able to remove system apps. However, I always advised do a complete backup 1st before you try to explore manually removing pre-installed apps you dont want, bcoz there are core apps (home launchers, messanging, browsers, etc..) Android needs to check after a boot. you might end up with a lot of "SYSTEM UI" force clossing and unable to use the phone (SOFTBRICKED)
