Xiaomi Redmi 8 is one of the most popular budget smartphones of the brand, but even it is not immune to freezes. The screen does not respond to touch, the phone does not turn off in the usual way, and the battery is discharged before the eyes? 90% of cases will help forced reboot - a procedure that zeroes temporary system errors without losing data. However, not everyone knows that Redmi 8 has 4 hardware methods of reboot (including hidden Fastboot mode), and their improper use can exacerbate the problem.
This article provides detailed instructions for all scenarios, from basic hard reset to ADB recovery if a smartphone has turned into a brick. We also look at why Redmi 8 can freeze tight (spoiler: not only software is to blame), and what to do if the phone doesn't turn on after a reboot. All methods are tested on current versions of MIUI 14 and Android 12.
Why Redmi 8 may require a forced reboot
Smartphone freezes rarely happen "just like that." Redmi 8 is most often to blame:
- 🔋 Critical battery discharge (below 5%) The power controller blocks the on-set even if you've connected charging.
- 🤖 Failures in MIUI. Especially after the updates "over the air» (OTA) Or hand-held firmware through Recovery.
- 🎮 Overheating of the processor. Redmi 8 on Snapdragon 439 is prone to trottling at long loads (games, video rendering).
- 💾 Damaged system files, such as after a faulty disconnection from the PC or a failure when writing to a microSD.
- 🛠️ Hardware malfunctions: departed battery plume, damaged motherboard.
If the phone doesn't respond to the power button, but it vibrates or flashes the notification indicator, it's probably a software problem, in which case a forced reboot will help. If the smartphone is completely dead (no vibration, no heat, no charging), the reasons can be more serious - from a bloated battery to a short circuit.
Method 1: Classical Forced Reset (Hard Reset)
It is the safest and most versatile method that works even when the screen is completely frozen, and is suitable for the Redmi 8, Redmi 8A and other Snapdragon 4xx models.
Instructions:
- Press the power button and the volume button at the same time.
- Hold them for 10-15 seconds until the screen goes out and the Redmi logo appears.
- Release the buttons - the phone will start to restart in normal mode.
If the smartphone freezes again after that, repeat the procedure, but hold the buttons for up to 20 seconds. This will force the power to turn off, even if the software does not respond.
☑️ Preparation for Hard Reset
⚠️ Note: If after a forced reboot the phone requires you to enter a password, but the keyboard does not appear - this is a sign of a failure in the System module UI. Try to connect the keyboard to OTG or perform reset via Recovery (see Method 3).
Method 2: Reboot via Fastboot (if the screen is running but the system is lagging)
If your smartphone responds to touch, but slows down or prevents you from calling the shutdown menu, you can use Fastboot mode, which is softer than Hard Reset, and keeps all the processes open.
Step-by-step:
- Connect Redmi 8 to charging (recommended).
- Press the power button + volume reduction for 5-7 seconds until the screen with the Fastboot appears (Android robot and the inscription FASTBOOT).
- Use the volume button down to select Reboot.
- Confirm the choice of the power button.
If the Fastboot menu doesn't have a Reboot option, your Redmi 8 has custom firmware installed.
- 🔌 Connect your phone to your PC through USB.
- 🖥️ Open the command line and type in: fastboot reboot
💡
If the phone brakes again after rebooting via Fastboot, check the free space in memory (less than 1 GB can cause lags) and turn off background sync in Settings → Accounts.
Method 3: Reboot with Recovery Mode (if the phone doesn't turn on)
If Redmi 8 doesn’t respond to Hard Reset or is stuck on the MI logo, you’ll need access to the Recovery menu, which will also help if the phone turns on but shuts off immediately (cyclic reboot).
How to log in to Recovery:
- Turn off the phone (if it is on, do Hard Reset from Method 1).
- Press the power button + increase volume and hold until the MI logo appears.
- Release the power button, but keep increasing the volume until the Recovery menu appears.
In the Recovery menu, use the volume buttons for navigation and the power button for confirmation.
- Select the Reboot option → Reboot to System.
- If this item is missing, select Wipe data → Wipe cache, then go back to the main menu and reboot.
| Recovery menu item | Action. | When to use |
|---|---|---|
| Reboot to System | A normal reboot. | If the phone is frozen, but the system is not damaged |
| Wipe cache | Clearing the cache | If after the MIUI update, lags appeared |
| Wipe data | Reset to factory settings | Only if other methods have not worked (delete all data!) |
| Connect with MIAssistant | Connecting to a PC for recovery | If the phone is in a brick (requires Mi Flash Tool) |
⚠️ Warning: If the Recovery menu displays characters or unknown characters, it's a sign of a damaged recovery section. Don't try to pick anything! Better connect your phone to your PC and use the Mi Flash Tool to flash back.
Method 4: Reboot through ADB (for advanced users)
If you have access to a PC and USB debugging enabled, you can restart Redmi 8 via the command line.
- 🔄 The phone is getting stuck but reacts to a PC connection (defined as a device).
- 🔧 You need to reboot to Fastboot or Recovery without using buttons.
- 📱 The screen is broken, but the sensor is partially working.
Instructions:
- Connect Redmi 8 to your PC via USB-cable (original!).
- Open the command prompt (Win + R → cmd) and type: adb devices If the device is determined (the serial number will appear), move to the next step. If not, check the drivers or enable debugging in Settings → About Phone → MIUI version (tap 7 times).
- For a normal reboot, type: adb reboot
- Recovery: Adb Reboot Recovery
- For reboot in Fastboot: adb reboot bootloader
If the adb commands don’t work, try:
- 🔌 Reconnect the cable (use the port) USB 2.0 on PC).
- 🔄 Restart your PC and phone.
- 📥 Install Mi. PC Suite for Automatic Driver Installation.
What if the ADB can’t see the device?
Method 5: Hardware reset (if the phone doesn't respond at all)
If Redmi 8 is not powered on, does not vibrate when charging, and is not detected by a PC, this may indicate:
- 🔋 Full discharge of the battery (even if the indicator is on fire).
- 🔌 Failure of the power controller (often after falling or getting moisture).
- 🛠️ Battery plume dump (typical problem for Redmi 8 after 2-3 years of use).
What you can do on your own:
- Pump up the battery: Connect the charge for 30 to 60 minutes (use the original 10W power supply). Try turning the phone on while holding the power button for 20 to 30 seconds.
- Check the contacts: If you have any experience with disassembly, open the back cover and check if the battery plume has passed. Check the board for bloated capacitors or traces of oxidation.
Use the test item
Xiaomi
- Connect the charging and press the power button + both volume buttons for 10 seconds.
- If the phone shows signs of life (vibration, flashing indicator) – repeat Hard Reset.
⚠️ Attention: If after these manipulations the phone still does not turn on, but warms up when connecting the charging - this is a sign of a short circuit. Further attempts to turn on may damage the motherboard.
💡
If Xiaomi Redmi 8 does not respond to charging and buttons, in 70% of cases the battery or plume is to blame. Self-repair is possible only with experience - without it, the risk of damage to the board increases 3 times.
What to do if Redmi 8 does not turn on after restart
A situation where the phone has restarted but does not turn on beyond the logo (or shuts down after a few seconds) is called a bootloop.
- 🔄 Failed update MIUI (damaged firmware files).
- 📱 Core conflict (if custom software was installed).
- 💾 The boot section is damaged (for example, after incorrect disconnection from the PC).
Decisions (in order of complexity):
- Clear cache via Recovery: Log in to Recovery (see Method 3). Select Wipe cache, then reboot.
- Fastboot Flash: Download the official firmware for Redmi 8 (codenamed olive) from MIUI Downloads. Use the Mi Flash Tool to install (spoiler instructions below).
Reset to factory settings
- In Recovery, select Wipe Data → Wipe All Data.
- ⚠️ All data will be deleted, including photos and apps!
