Xiaomi Redmi 4X — One of the most popular budget smartphones of the brand, but even it is not immune to problems with power. If your device stopped responding to the power button, do not rush to panic: in 80% of cases, the problem can be solved independently without contacting the service center. In this article, we will analyze all possible causes - from the banal discharge of the battery to serious hardware malfunctions, as well as give step-by-step instructions with photos and videos how to bring the phone back to life.
Feature of Redmi 4X (The code name santoni is that it has a fixed battery and a specific power circuit that sometimes fails, for example, after a deep discharge, the battery controller can block charging, and an incorrect firmware update can lead to a "brick" (complete failure). We’ve put together all the working recovery methods, including hardware reset, Fastboot firmware, and even ways to revive a phone with a faulty power button.
Important: if the phone responds to charging (lights up, vibrates, shows the Mi logo), but does not load further, that's one scenario. If it is completely dead (no response to buttons, charging, PC connection), another. In the article, we divided the solutions for each case.
1.Diagnostics: Why Xiaomi Redmi is not included 4X
Before you try to resuscitate your phone, you need to determine the cause of the malfunction, and here are the main symptoms and their possible sources:
- 🔋 No reaction to the power button, but the charging indicator is on → Problems with battery, power controller or firmware.
- 📵 The phone does not respond to anything (no vibration, light, sounds) → hardware failure (short circuit, damage to the motherboard).
- 🔄 The Mi logo lights up, but no longer loads. → Damaging system files, failed updates.
- 💥 The phone gets overheated when you try to turn on → battery failure.
- 🔌 Responds only to connection to charging → power button or plume problem.
The most common reasons for Redmi 4X:
- Deep battery discharge (controller blocks charging).
- Failure of firmware after updating or incorrect shutdown.
- Failure of the power button (wear, oxidation of contacts).
- Damage to the charging connector (poor contact, pollution).
- Hardware failure (burnt out power chip, short circuit).
If your phone falls into the water or is hit hard, you have a 90% chance of hardware failure, and otherwise, try software first.
2.The first steps: what to do if the phone does not respond to the button
Start with basic actions – they help in 60% of cases.
Checking of charging and battery
- 🔌 Connect your phone to the original charger (or a quality Quick Charge 2.0-enabled counterpart).
- ⏳ Leave at least 30 to 60 minutes on charge – even if the indicator is not on.
- 🔄 Try another ROM, cable, or socket (sometimes a problem with the power supply).
- 📱 If the charging indicator caught fire, but the phone does not turn on – hold the power button for 15-20 seconds (sometimes a forced reboot helps).
Important: if the battery is discharged to zero, the controller can block charging, in which case only forced charging will help (see section 4).
2.2 Forced reset (Hard Reset)
If the phone is stuck on the Mi logo or does not respond to the button, try the hardware reset:
- Press the power button. + Increase volume by 10-15 seconds.
- If the Mi logo appears, release the buttons - the phone should reboot.
- If there is no reaction, repeat the action with the combination of nutrition. + volume-reducing.
On the Redmi. 4X Sometimes a trick works: connect the phone to charge and simultaneously pinch the power. + Both volume buttons for 20 seconds. This can unlock the power controller.
☑️ Checklist before deep diagnosis
Check for physical damage
Look at the phone for:
- 💧 Traces of moisture (oxidation on the charging connector, under the buttons).
- 🔧 Battery bloating (if the back cover is moving away).
- 🔌 Damage to the charging connector (bent contacts, dirt).
- 📱 Cracks on the screen or body (may indicate impact).
If traces of water are found, do not connect the phone to charge - this can cause a short circuit, in which case disassembly and cleaning with alcohol are required.
💡
If the phone falls into water, remove the battery immediately (if possible) and dry in rice or silica gel for 24-48 hours. Don't use a hair dryer - it can melt components!
3. Software recovery methods
If the phone has any response to charging or buttons (vibrates, shows the logo) but doesn't load, the problem is probably the firmware. Let's look at all the recovery options.
3.1 Entering Recovery Mode and Resetting Settings
If the phone is turned on but hangs on the logo, try resetting the settings via Recovery:
- Turn off the phone (if it's on, hold the power button for 10 seconds).
- Press the power + increase the volume until the Mi logo appears.

- Select Wipe Data → Wipe All Data (reset to factory settings).
- Confirm the action and wait for the reboot.
Warning: This method will delete all the data on your phone (photos, contacts, messages) if you have Mi Account enabled, you will need to enter your username and password after reset.
3.2. firmware via Fastboot (if the phone is determined by the PC)
If the phone does not boot, but the computer sees it in Fastboot mode, you can reflash it with the official firmware:
- Download Mi Flash Tool from Xiaomi’s official website and firmware for Redmi 4X (santoni) (Fastboot version).
- Install ADB and Fastboot drivers (you can use Mi PC Suite).
- Connect the phone to the PC by clamping the power + volume reduction (a hare should appear in a hat-eared header - a sign of the Fastboot mode).
- Launch the Mi Flash Tool, select the downloaded firmware and press Flash.
- Wait for the process to end (5-10 minutes) and reboot.
References to official instruments:
- Firmware for Redmi 4X (Choose the Fastboot version for the Santoni model).
- Mi Flash Tool (Firmware Utility)
Important: Fastboot removes all data, but restores performance even after serious failures.

3.3. Firmware through EDL (emergency)
If the phone is not defined in Fastboot, but reacts to the connection to the PC (for example, it makes a connection sound), you can try flashing it through the phone. EDL (This method is more complex and requires:
- 🖥️ Special cable. EDL (or circuitry).
- 📥 Firmware in.mbn format and Mi Flash Pro utilities.
- 🔧 Skills of working with Qualcomm devices.
Detailed instructions for the firmware through EDL for Redmi 4X You'll find it on the forums. 4PDA Beware: the wrong actions can finally "kill" the phone.
4 Hardware methods: what to do if the phone does not respond at all
If Redmi 4X does not show signs of life (no indication, vibration, reaction to charging), you will have to resort to more radical measures.
Forced recharging of the battery
If the battery is empty, the power controller can block the charge, to wake up the phone:
- Connect the phone to charge and leave it for 1-2 hours (even if the indicator does not burn).
- If there is no reaction, try closing the battery contacts (only for power users!):
⚠️ Warning: You can only close the battery contacts if you are confident in your actions.
Check the power button and the plume
If the phone is responding to charging (the indicator is on), but does not turn on from the button, the problem may be:
- 🔘 Faulty power button (wear and tear, oxidation).
- 🔌 Damaged button plume (frequent problem after falls).
How to check:
- Connect the phone to charging – if it starts to boot, the problem is the button.
- Take the phone apart and check the integrity of the plume (it should not be ruptured or oxidized).
- Try to close the contacts of the power button on the board (you need a tester or tweezers).
If the button is faulty, it can be replaced by yourself (the cost of a new one is about 200-300 rubles) or taken to the service.
Diagnostics of the motherboard
If the phone doesn’t respond to anything, there may be serious hardware problems:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The phone warms up when connected to charging | Short circuit on board | Diagnostics in the service (multimeter check) |
| Charging indicator flashes, but the phone does not turn on | Power Controller Failure (PMIC) | Replacement of the chip or flashing through EDL |
| The phone vibrates, but the screen doesn't turn on. | Damage to the display plume or graphics chip | Replacement of a plume or diagnostics of a fee |
| Smell of smoke when trying to turn on | Burnt-out element on the board (most often) UFS-accumulator) | Repair in the service (chip replacement) |
⚠️ Attention: if you smell burning or the phone is getting very hot, do not connect it to the charger and do not try to turn it on! This can lead to fire.
