The Xiaomi Redmi 6, released in 2018, is still a popular budget smartphone due to its balanced performance and reliability. However, even time-tested devices have crashes: the phone can suddenly stop responding to the on button, hang on the screensaver of MIUI or not show signs of life at all, the reasons range from banal battery discharge to serious hardware breakdowns.
In this article, we will look at all possible scenarios for why Redmi 6 doesn’t turn on, from software glitches to physical damage, how to distinguish a soft failure from a critical failure, what manipulations you can do yourself, and when you carry your phone to the service, and focus on non-disassembly diagnostics: checking charging, resetting, and flashing through Fastboot.
Important: If your Redmi 6 has fallen into the water, been hit or overheated, some methods can make things worse, so you should call the experts right away, and for everyone else, we should start step-by-step recovery.
1.Primary diagnosis: identify symptoms
Before you try to reanimate a smartphone, you need to know exactly how it doesn't turn on, and the choice of repair method depends on it. Here are the key signs and their possible reasons:
If you don't get into any of these situations, it's probably a combined problem, like a phone that might have run down to zero because of a firmware failure, and then it doesn't turn on after it's recharged because of a damaged bootloader, and in these situations, you have to take the order of the situation: check the charging first, then try the software methods, and then last, disassemble the device.
2. Charging check: basic steps
Up to 70% of Redmi 6 cases are due to a dead battery or power chain problem.
- Try "forced" charging: plug the cable, then press the power button for 20 to 30 seconds, sometimes helping to "wake up" the controller.
If the phone is not showing any signs of life after this manipulation, move on to the next step, especially if the device heats up during charging - this may indicate a battery failure or short circuit on the board, in which case further attempts to turn on are fraught with fire!

3. Hard reboot and reset settings
If the phone vibrates or shows the MIUI logo but does not load further, the problem is more software-based, in which cases forced reboot or factory reset helps.
Method 1: Forced resetting
Press the Power + Volume button combination for 10 to 15 seconds. If the phone responds, it will restart. This works if the system is getting stuck during the boot phase.
Method 2: Recovery Resetting
- Turn off the phone (if it is frozen, press the power button for 20 seconds).
- Press Power + Volume Up until the Mi logo appears, then let go.
- From the Recovery menu, select Wipe Data → Wipe All Data (use volume buttons for navigation, power for confirmation).
- After reset, select Reboot → Reboot to System.
⚠️ Warning: Recovery will delete all data on your phone, including photos and apps, and if you have Mi Account enabled and synced, some of the data can be restored once you log in to your account.
If the phone doesn't turn on or freezes at the same stage after the reset, the problem is deeper - the bootloader or firmware may be damaged, in which case only flashing through Fastboot (more about this in the next section) will help.
4. Fastboot flashing: When nothing helps
If Redmi 6 doesn’t boot even after a reset, but it reacts to a PC connection (defined as Qualcomm HS-USB QDLoader 9008 in Device Manager), you’ll need to:
- 🖥️ Windows computer 7/10/11;
- 🔌 Original. USB-cable;
- 📥 Fastboot firmware for Redmi 6 (The version must match your model: cereus for the global version or cereus_in Indian);
- 🛠️ The Mi Flash Tool.
Step-by-step:
- Download and install the firmware for your model. Unpack the archive into a folder without Cyrillic characters.
- Install Qualcomm drivers (if the phone is defined as QDLoader, the driver is already installed).
- Launch the Mi Flash Tool, press Select and specify the path to the firmware folder.
- Connect the phone to the PC, holding Volume Down + Power (a black screen labeled Fastboot should appear).
- In the Mi Flash Tool, press Refresh — the device must be determined. Select Clean All mode and press Flash.
- Wait for the process to finish (5-10 minutes) and the phone will automatically restart.
⚠️ Attention: Continuous power is critical! If the cable shuts down or the computer restarts during firmware, the phone can turn into a brick. Use a full-charge laptop or a PC with a UPS.
If the phone still does not turn on after firmware, check:
- 🔌 Correct cable connection (try another port) USB);
- 📁 Compatibility with your model (cereus vs) cereus_in);
- 🔧 Integrity USB-Port on the phone (possibly oxidized contacts).
What if the Mi Flash Tool can't see the phone?
5. Hardware malfunctions: when it is impossible to disassemble
If all software methods are exhausted and Redmi 6 is still not turned on, the problem lies in the hardware.
| Malfunction | Signs. | Possible repairs |
|---|---|---|
| Faulty battery | The phone is turned on only from charging, quickly discharges, bloated body | Replacement of the battery (cost ~ 1000-1500 rubles) |
| Power supply/display plume damaged | The screen isn't on, but the phone vibrates; the image is there, but no backlight. | Replacement of the plume (from 800 rubles) |
| The switch button is faulty. | The phone responds to charging, but does not turn on the button | Replacement of a button or cleaning contacts (from 500 rubles) |
| Short circuit on board | The phone warms, discharges quickly, does not turn on after falling / getting moisture | Diagnosis with a multimeter, soldering of elements (from 2000 rubles) |
| Power controller burned | No reaction to charging, battery not charged | Replacement of the controller (from 1500 rubles) |
If you do not have experience in electronics repair, it is not recommended to disassemble the phone yourself. Modern Xiaomi smartphones are assembled on glue and thin plumes - one wrong movement can lead to additional breakdowns. It is better to contact the service center, having previously learned the cost of diagnosis (usually free or ~ 300 rubles).
💡
Before visiting the service, take a photo of the IMEI phone (printed on the box or under the battery) to help avoid replacing components and prove that the device is yours.
6. Frequent user errors: what not to do
In trying to revive Redmi 6, many people are doing things that only make the problem worse.
- 🔥 Heating your phone with a hair dryer or battery – this can melt plumes or damage the battery.
- 💧 Immerse in rice or alcohol when moisture is ingested - rice does not absorb water from the inside, and alcohol can damage the coating of boards.
- ⚡ Connect to unstable power sources (for example, to a car lighter without an adapter).
- 🔨 Independently solder board without experience – modern smartphones have multi-layer boards with microelements.
- 📱 Install unofficial firmware without compatibility checks – this can finally “kill” the bootloader.
Also, don't believe tips like "knock on the phone" or "blow into the connector," which are not technically sound and can cause additional harm, and if you're not sure what you're doing, you should consult a specialist.
💡
90% of Redmi 6 non-physical malfunctions are software-based, charging, resetting or flashing, and hardware repairs are only required 10% of the time, but it’s best left to the professionals.
7. Alternative methods: if nothing has worked
If all of the above methods fail, there are still a few options:
Method 1: Testpoint (EDL)
If the phone is defined as a Qualcomm HS-USB QDLoader 9008, but the Mi Flash Tool does not help, you can try to switch it to EDL (Emergency Download Mode) mode through test points.
- Disassemble the phone and find EDL points on the board (usually signed or marked on the diagram for Redmi 6).
- Lock them with tweezers or a needle while connecting the cable to the PC.
- The phone should be defined as QDLoader, after which you can flash it through the Mi Flash Tool or QFil.
⚠️ Warning: Testpoint closure requires care! Incorrect touching can damage the board.This method is recommended only for advanced users.
Method 2: Feedback with Xiaomi
If your Redmi 6 is warranty-free (unlikely for a 2018 model, but possible if you bought it later), contact Xiaomi's official service. Even without warranty, they can offer diagnostics or repairs at a fixed price.
Method 3: Buying parts for self-repair
If you are willing to take the risk, you can order spare parts on AliExpress or in specialized stores:
- 🔋 Battery for Redmi 6 (article: BH41) — ~800-1200 rubles.
- 📱 Trail display with touchscreen — ~1500–2,000 rubles.
- 🔌 Activation button — ~300-500 rubles.
When replacing components, be sure to be compatible – for example, the batteries from the Redmi 6A will not be suitable for the Redmi 6.
