Xiaomi Redmi's screen cracked after a fall, the phone doesn't respond to charging, or the device turned into a brick after a failed MIUI update? Situations where the smartphone refuses to turn on but has important photos, correspondence or work documents that are familiar to many. Fortunately, even in the most severe cases - from software failures to physical damage to the board - there are ways to extract data. The main thing is to act systematically and avoid typical errors that can finally destroy information.
In this article, we’ll look at 5 proven methods, from simple (connecting to a PC in Fastboot mode) to extreme (direct memory reading via an eMMC chip), illustrated with step-by-step instructions, risk warnings and compatibility tables with popular Redmi models (from Redmi Note 4 to Redmi 12), with a focus on the nuances of working with encrypted partitions (starting with MIUI 12) and phones that have damaged motherboards.
Before you start, if the phone is responding to charging (vibrates, lights up), but it doesn't turn on, the chances of a successful data recovery are 80-90%. In cases where the device is completely dead (no power button reaction, no heat), you will need specialized tools or help from a service center. But even here, not all is lost: modern laboratories can extract data even from damaged memory chips.
1. Connection in Fastboot mode: when the phone is "half-half"
Fastboot mode is an “emergency login” to Xiaomi’s system that works even when a bootloader or firmware is damaged. If the phone has any reaction to a USB connection (e.g., making a sound or being identified as an unknown device in Task Manager), this method is worth trying first.
To activate Fastboot on a broken Redmi:
- 🔌 Connect your phone to your PC via the original cable (preferably) USB 2.0 - it's more stable).
- 🖥️ Press the Volume button down. + Power for 10-15 seconds. If the screen is not working, be guided by vibration.
- 📥 Install Mi Flash Tool drivers (download from Xiaomi’s official website) and check if the device is detected in the command line:
fastboot devicesIf you see the serial number in response, you can start retrieving the data. If you don't, try another cable or USB port.
⚠️ Note: On Redmi models with MIUI 13+ and on OEM Unlock Fastboot mode can block access to user data. In this case, you will need to unlock the bootloader (see section 3).
To copy files, use the utilities:
- 📁 ADB Pull (if the phone is defined as a device in adb devices:
- 🔧 Mi PC Suite (official software from Xiaomi, but it works unstable with damaged devices).
- 🛠️ Dr.Fone or Tenorshare 4uKey (Payable, but support data extraction from locked phones).
☑️ What to check before extracting data in Fastboot
2.Use of Recovery Mode: If the phone is turned on but not loaded
If Redmi vibrates when you press the power button, but gets stuck on the logo MIUI or goes into an endless reboot, try to log into Recovery Mode. This mode allows you to copy data to an external drive (a flash drive or a flash drive). SD-map without full system load.
Instructions for entering Recovery:
- Turn off the phone (if it is getting stuck, press Power + Volume up for 20 seconds).
- Press Power + Volume up before the Mi Recovery logo appears.
- Select Mount → Enable MTP (if the screen is working). If the screen is not responsive, connect the phone to the PC, it should be defined as a removable disk.
Mi Recovery has options available:
- 📤 Backup – Create a backup copy of the SD-The map (not working on all models).
- 🔄 Wipe Data – Do not select this item, otherwise the data will be erased!
- 📥 Install Update – You can try to flash your phone, but it’s risky (see section 4).
💡
If Recovery Mode doesn't define your phone as a removable drive, try connecting it to another PC with the antivirus disabled, and sometimes security programs block access to damaged partitions.
On Redmi Note 8/9/10 and later in Recovery, you may need to enter a password from Mi Account. If you don’t remember it, use the official Xiaomi account recovery service (account.xiaomi.com).
3. Unlock the bootloader: if the data is blocked by MIUI
Starting with MIUI 12, Xiaomi encrypts user data by default, which means that even if you connect your phone in Fastboot or EDL mode, files will not be available without unlocking the bootloader Unlock.
- ⏳ Requires a binding to Mi Account (account must be created in 7 minutes)+ days before unlocking).
- 📱 The phone should be turned on somehow (at least in Fastboot).
- 🔓 After unlocking, all settings will be reset, but the files on the internal memory will remain.
Step-by-step:
- Download Mi Unlock Tool from Xiaomi (en.miui.com/unlock).
- Log in to your Mi Account on your PC and link your phone (in Mi Cloud settings).
- Connect Redmi in Fastboot mode and launch the utility. Press Unlock.
- Wait for the SMS with the confirmation code (comes to the number associated with the account).
⚠️ Note: On Redmi Note models 11/12 Xiaomi can request additional confirmation via photo IMEI. If the phone is not turned on, find out IMEI can be done from the box or through the command line: fastboot getvar imei After unlocking the bootloader can be used TWRP (custom recovery) to create a full backup. TWRP On new Redmi models, it often triggers the Anti-Rollback (running back protection) that can finally kill the phone. 10/11/12 Only official data extraction methods are recommended. 📊 Your phone is identified in Fastboot?Yes, but the data is locked Yes, and I was able to copy the files No, the phone is completely dead I don't know how to check 4. Firmware in mode EDL: Extreme case for "bricks" Mode EDL (Emergency Download Mode is a hidden firmware mode that is activated when critical crashes occur, allowing you to reflash your phone even if the bootloader is damaged. EDL It's impossible -- this is just a method to restore the phone to work, so you can use Fastboot or Recovery. EDL: 🔧 Hardware method: close the test points on the motherboard (requires disassembly of the phone).

EDL Does the phone not work? if the phone is in EDL phone does not respond, check: 1. Correctness of the selected firmware (must match the model and region, for example, Redmi Note 8 Global). 2. Integrity USB-cable (damaged wires can interrupt firmware). 3. Short circuit on the board (after closing points) EDL If nothing helps, contact the service - perhaps damaged eMMC chip or power controller. 5. Direct memory reading (Chip-Off): when the phone is dead If Xiaomi Redmi is not showing signs of life (not warm, not detected by the user). USB, It doesn’t vibrate, but you’re sure the battery isn’t the problem, so there’s a last chance you can read the data directly from the memory chip. This method requires specialized equipment and soldering skills, but allows you to restore the 100% information, including deleted files: 🔬 The phone is disassembled, and a memory chip (eMMC or) is removed from the motherboard. UFS). 🔥 The chip is soldered to the adapter (eMMC Reader or UFS Reader). 💾 Using the software (Flash Extractor, ChipGenius) reads a full memory dump. 🔍 The necessary files (photos, contacts, messages) are extracted from the dump using hex editors. 5 000 before 20 000 (depending on the chip model and soldering complexity: 🛒 Temperature controlled soldering station (e.g. Quicko) T12). 🔧 Adapter for chip (e.g. eMMC) 153/162/169 BGA). 💻 Programmer (RT809H or easyJTAG). The most difficult cases: 🔥 Chips. UFS 3.1 (installed at Redmi) K50, Redmi 12 Pro – require high-precision soldering due to the small step of contacts. 💥 Damaged memory controllers – data can be fragmented. 🔒 Encrypted partitions (starting with Android 10) – you will need an encryption key (usually stored in a chip) CPU). 💡Chip-Off is the only method that works even if the phone is drowned, burned or crushed. But it's destructive: once you take the chip off, you can't fix it. 6 Alternatives: cloud backups and a lot of other ways to do it. SIM-If physical data recovery is impossible or too expensive, check cloud backups and alternative sources: ☁️ Mi Cloud: Even if the phone doesn't turn on, photos, contacts and notes could sync to the cloud. → Backup copies). 📱 Google Account: If Backup by Google was enabled, app data (including WhatsApp, Telegram) can be restored on a new phone. 📞 SIM-map: contacts and SMS could have been SIM (Modern Redmis rarely use this feature). 💬 Social networks: correspondence from VK, Telegram or WhatsApp are often duplicated in web versions of instant messengers. How to check if sync with Mi Cloud was enabled: Go to i.mi.com and log in. In Devices section, check if your Redmi is tied. In the Cloud → Backups see the date of the last backup. If you have a backup but it is incomplete (for example, no photo), try to restore data via Google Photos (photos.google.com) or Disk Digger (an application to scan damaged drives). 💡If you used Xiaomi with a corporate account (for example, through Microsoft Intune), the data could be synchronized with the working cloud. IT-division. FAQ: Frequent questions about data recovery with Xiaomi Redmi Can data be extracted if the phone is not turned on and is not detected by the phone? USB? Yes, but only in two ways: Chip-Off – removing the memory chip and reading through the programmer. JTAG — Connecting to test contacts on the board (not all models) both require specialized equipment, they can't be implemented at home, the phone turns on, but asks for a password. Can you bypass the lock without losing data? 9 (s MIUI 11 You can try: Log in to Recovery and reset password through ADB (Adb shell rm /data/system/gesture.key). Use utilities like this. 4uKey (fee-paying but retains data). On new models (Redmi) 10/11/12) Bypassing the lock without losing data is impossible - you will need to unlock the bootloader (see section). 3). How much does it cost to recover data in a service center? Type of damage (₽)Timeline Program failure (Fastboot/Recovery)1 500–3 0001–2 Damaged screen (but phone switched on)2 000–5 0002–3 Chip-Off (Removal of the memory chip)5 000–20 0003–7 Recovery after drowning/fire10 000–30 0007–14 Prices depend on the region and the complexity of work. 20–30% Is it possible to recover deleted files after resetting? Yes, but with the reservation: If the reset was made through Recovery, the data can be restored using DiskDigger or EaseUS MobiSaver (provided that no new files were written to the phone). If the reset is done via Fastboot, the chances are minimal, the data is overwritten. F2FS (The file system on the new Redmis is almost impossible to recover deleted files. What data can't be recovered under any circumstances? Unfortunately, some types of data are lost forever: 🔐 Passwords from applications (stored in encrypted form in the form of /data/system). 📱 Encrypted application data (such as banking applications or Signal). 🎮 Save games if they are not synced to the cloud. 📡 Wi-Fi and Bluetooth settings (stored in the wpa_supplicant.conf, It is also impossible to recover data from phones that have damaged the memory controller (eMMC or other devices). UFS) — In this case, the chip does not respond even when connected directly.
