This file was deleted by Author. But you can install global cust.img or try to skip this step
Install the MIUI region fix in TWRP: install- select the zip file-confirmation (you can download it at the end of the article, if you want a completely cleaned system from any Chinese social networks)
4. Put ROM to phone and flash it
Install the downloaded zip archive with firmware in TWRP: Install-select zip file with firmware-confirmation
5. Wipe data / Factory reset
Go to wipe-wipe data, cache, dalvik cache-confirm. (this will erase all your installed applications and data from them; photos, videos and downloads will remain)
After that, reboot into the system and check if the system is working normally (the first boot will take about 2-3 minutes) 6. Flash TWRP and boot to TWRP then reboot to system
Author add this step. But I dont know why we have to do this step. Make your choice
7. Update google play app before login to a google account
Make the first system setup and go to the play market. DO NOT GO TO A Google ACCOUNT, check for application updates through the three dots above and update Google Services, Android System Webview and then Chrome (the rest is at your discretion). Now you can log into your account and download your apps.
What is it? This is the firmware based on the stable Chinese Miui 12.0.18 with changes.
What's changed: Removed most of the unused Chinese apps. Added all languages from global MIUI versions. Added basic gapps + gmail + chrome + gboard + maps. Built-in Magisk 20.4, also TWRP that you had before installing this firmware will be saved. GPay works with Magisk Hide.
Cons of the firmware: The following applications are translated only into three languages (Chinese, English, Russian): camera, mi account, security, initial setup. No OTA updates (cannot be installed via ota system updates, otherwise bootloop, but you can install the firmware via twrp using a full zip rom archive or restore via fastboot and miflash) maybe you will find more cons and tell me
With Andoid 11, you should not flash, since some phones have protection against downgrading, perhaps ours is the same, first try downgrading using the fastboot image and Miflash.
Installation:
1. Install zip archive with firmware in twrp
2. Go to wipe-wipe data, cache, dalvik cache-confirm.
After that, reboot into the system (the first activation will take about 2-3 minutes)
Thanks to:
Almost all knowledge came from @MeTT1S
Application translation was done in BatchApkTool
The firmware was compiled in UKA
PS: I also recommend that you install the "globalization" module so that global applications such as cleaning, weather, music, etc. work correctly. Also, you will have a choice of region (I advise you to select United states for better sound and smoother operation) the module is called h.zip and is installed in the magisk manager. module here
Small explanations:
Magisk: Built in, after first opening magisk manager will offer you additional installation. so you need to agree, the phone will download 5MB, reboot and everything will be ready to use.
Gpay: works, you just need to update google services, then download google pay in the play market, without opening google pay go to magisk manager- settings- enable magisk hide. Then you need to leave google pay checkbox and everything will work.
Gpay is not available: If you opened gpay before turning on magisk hide, then most likely google pay writes that: you have a root, payment is not available. in this case, you need to clear the cache and data of two applications: google pay and google services, after that it should work.
Bootloop: If after installing the magisk module or modifying the system partition, a bootloop happened or you reboot into fastboot, then the solution is to go to twrp and flash the same archive with the firmware without wipes
(K30U_GlobalEdition_MIUI_Stable_12.018_v1.0.zip), often helps to keep the system working and keep your data.
