If you notice a "Developer Mode is on" notification in the curtain, there are constant warnings about how to use the device. USB-debugging, or just want to return the smartphone to the standard state β this article will help you understand.
Unlike most instructions on the web, here weβll look at not only basic ways to disable, but also the nuances associated with the Redmi Note 8T (model M1908C3XG). For example, why the developer menu may reappear after resetting, or how to properly deactivate ADB debugging so as not to block future MIUI updates.
Important: the procedure differs from the standard on new Xiaomi models (for example, Redmi Note 12 or POCO X5), where the MIUI interface has undergone changes, and this takes into account the features of the MIUI 12-14 firmware for the Redmi Note 8T, including global and Chinese versions.
Why is the developer mode not disabled in the standard way?
Many users are faced with a situation where, after clicking on the "Developer Mode" switch in the settings, it again activates itself.
- π Automatically Enabled When Connecting to a PC: If You Have Previously Allowed USB-debugging, the system can re-activate the mode when a connection to the computer is detected.
- π± Residual files MIUI: on the Redmi Note 8T Some of the developer mode parameters are saved in the file /data/property/persist.sys.usb.config, even after manual shutdown.
- π§ Application conflicts: programs like ADB AppControl or Tasker can software enable mode if they have superuser rights.

If you have already tried to disable mode via Settings β About Phone β MIUI version (7 times pressed), but failed - the problem is most likely in one of the above points. Next, we will analyze the solutions for each case.
Method 1: Standard shutdown via MIUI settings
Let's start with the simplest method, which works 70 percent of the time, and it's only useful if the developer mode has been manually enabled and doesn't conflict with other settings:
- Open the settings (cog icon).
- Go to the About Phone section (usually at the bottom of the list).
- Find the MIUI version string and tap it 5 times in a row (not 7 times when you turn it on!) and the system should show a notification: "You're almost there!"
- Return to the main Settings menu β the βAdvancedβ section (or βAdvanced Settingsβ on global firmware).
- Select the Developer Options option (may be called the Developer Options).
- At the top of the screen, translate the developer mode slider to the off-site position.
If the "Developers" section has disappeared from the menu, the mode has been successfully deactivated. If not, move to the next method.

Method 3: Disconnect via ADB (for power users)
If previous methods didnβt work, and the developer mode is stubbornly returning, youβll have to use Android Debug Bridge (ADB), which requires a PC connection, but is guaranteed to work even on blocked firmware.
You'll need:
- π» Computer with Windows/Linux/macOS and installed Xiaomi drivers.
- π Original. USB-cable (importantly, cheap cables may not transmit data).
- π₯ Utility. ADB Tools (download from the official Google website).

adb shell settings put global usb_debugging_disabled 1What if the ADB canβt see the device?
Method 4: Reset to factory settings (extreme case)
If none of the methods worked, and the developer mode interferes with work (for example, blocks updates or causes failures in MIUI), then only a complete reset remains. On the Redmi Note 8T, you can do this in two ways:
| Method | Advantages | Deficiencies | Time. |
|---|---|---|---|
| Reset via settings | Just, it doesn't require a PC. | Deletes all data except files on the memory card | 5-10 minutes |
| Reset via Recovery | Guaranteedly removes all settings, including hidden ones | Requires a reboot, harder for beginners | 10-15 minutes |
| Through the Mi Flash Tool | Restores firmware from scratch, removes all bugs | Requires PC, risk of 'bricking' in case of error | 20-30 minutes |
We recommend starting with the first option:
- Create a backup of data (photos, contacts, messages) through Settings β System and device β Backup.

Instructions for users with Root:
- Install a file manager with Root support (such as Root Explorer or FX File Explorer).
- Go to /data/property/ and delete the files: persist.sys.usb.config persist.sys.debug.enabled
- Reboot your smartphone.
For users without Root (via ADB):
- Connect your smartphone to your PC and open the command line in the platform-tools folder.
- Follow the commands: adb shell su rm /data/property/persist.sys.usb.config rm /data/property/persist.sys.debug.enabled reboot
β οΈ Note: if after deleting files, the smartphone stopped booting - restore them through TWRP Recovery or reflash the device. This method is recommended only for advanced users!
