3.Poco X3 Pro firmware methods: which one to choose?
The choice of firmware method depends on your purpose and the current state of the device, and below is a comparison table with the pros and cons of each method.
| Method | Unlocking required | Data retained | Suitable for | Difficulty |
|---|---|---|---|---|
| Recovery (OFFICIAL) | ❌ No. | ✅ Yes (when choosing Update) | Update of official MIUI, fix bugs | ⭐⭐ (simple) |
| Fastboot (MI Flash) | ✅ Yes. | ❌ No (full reset) | Change of firmware region, downgrade (with the risk of anti-rollback) | ⭐⭐⭐ (middle-of-the-road) |
| EDL (Test Point) | ✅ Yes (or an authorized account) | ❌ No. | Restoration of bricks, firmware without Fastboot | ⭐⭐⭐⭐ (difficult) |
| Custom Recovery (TWRP) | ✅ Yes. | ✅ Yes (when choosing Install without wipe) | Install custom firmware (LineageOS, Pixel Experience) | ⭐⭐⭐⭐ (difficult) |
For most users, the best option is to run through Fastboot using the Mi Flash Tool, which allows you to change the firmware region (for example, from China to Global) or install a newer version of MIUI. However, it requires an unlocked bootloader and erases all data.
If you just need to upgrade without losing data, use Recovery. TWRP will be required to install custom firmware (like LineageOS 20), but installing it on the Poco X3 Pro has nuances due to vbmeta protection.
