Moreover, flashing with SPFT is the only option to repair (replace) damaged system software.

OTA (recovery) update

Manual (local) OTA update method instructions

• Copy the downloaded .zip file to the internal storage of your phone
• Go to Settings → About phone → Wireless update
• Tap the 3-dot menu button in the top right corner and select Local Updates
• Brows for the ...update.zip file and select it

It can update version 20211231 only

Optional method (in case if the manual OTA update gets stuck): Install from recovery

You need a microSD card (with at least 4GB capacity) installed in your phone!

• Copy the ...update.zip file to your SD card.
• Press and hold the volume-up and power buttons together until your phone restarts. As soon as the boot screen flashes up, release the power button and keep only the vol-up button pressed.
• In a few seconds, your phone boots into Recovery and you see a lying android figure with an exclamation mark in red triangle on its tummy, and ‘No command’. Release the vol-up button.
• Press and hold the power and vol-up buttons (in this order) together, then release them (first the vol-up button) to call the recovery menu. Now you can move with both volume buttons, and select an item with the power button.
• Move to ‘Apply update from SD card’ and select it.
• On the next screen brows for the update file and select it. The update process will start and needs a few minutes to be finished.
• After a successful installation, you can read the ''Install from SD card complete.'' message and the recovery menu is available again.
• Select 'Reboot system now'. Alternatively you can perform a factory data reset here by choosing 'Wipe data/factory reset'
  

Kind request from users:
Please report any kind of new issues you experience after installing this update only if you've already flashed this ROM with SP Flash Tool in Firmware Upgrade mode. In rare cases a FOTA update can cause more or less serious malfunctions but that means only the update process went wrong, not a badly developed ROM. An updated stock ROM, especially related to the basic functions will not cause any new issues but will solve some of the existing ones.

No, left Android 10. I have not experienced any substantial change.  At least something that would fix some BUG, ​​not one. I am angry!
