The official way to unlock the bootloader is through Mi Unlock Tool requires linking Mi account and waiting until 360 hours (15 days). Users found several workarounds on 4PDA, but most of them were closed in 2023. Current methods for today:
- Via EDL mode (emergency firmware) - requires an authorized account Xiaomi and a special cable. Risk of blocking your device forever!
- Exploiting a vulnerability in MIUI 12.0.3 - works only on older firmware versions. Instructions:
How to bypass the 360 hour wait?
1. Roll back to MIUI 12.0.3 via
Fastboot. 2. Install the patchno_verity_opt_encrypt.zipthroughTWRP. 3. LaunchMi Unlock Tooland unlock your bootloader without waiting. - Buying an unlocked device - on w3bsit3-dns.com there are verified sellers who sell Redmi Note 9 Pro with an already unlocked bootloader.
The most reliable way today is using services like MiFlashPro or XiaomiTool V2, but they are paid (~$5–$10). Free methods either do not work or require deep technical knowledge (for example, soldering testpoints to enter EDL).
If you have unlocked the bootloader, install it immediately OrangeFox Recovery instead of TWRP - it works better with dynamic partitions in new versions of MIUI.
4. Typical problems of Redmi Note 9 Pro and their solutions with w3bsit3-dns.com
Redmi Note 9 Pro has several “childhood diseases” that have not been corrected by Xiaomi even in the latest updates. Here are the most common problems and their solutions from the w3bsit3-dns.com community:
| Problem | Reason | Solution (4PDA) |
|---|---|---|
| Overheating when charging | Incorrect power controller calibration | Install kernel FrancoKernel or disable fast charging via AccA |
| NFC doesn't work after update | Resetting module settings | Reflash persist section through Fastboot |
| Spontaneous reboots | Conflict with Google Play Services | Roll back to version 23.18.15 through ADB |
| The camera produces a green tint | Defective matrix or ISP firmware | Flash vendor section from MIUI 12.5.3 |
One of the most annoying problems is rapid battery wear (loss of 20–30% capacity per year). On 4PDA they recommend:
- 🔋 Disable charging optimization in
Settings → Battery → Charging optimization. - 📉 Limit maximum charge to 80% via
AccA(battery calibration app). - 🔄 Once every 3 months, perform a full discharge/charge cycle (0–100%).
