Xiaomi’s smartphone firmware through the official Mi Flash Tool is a process that scares many users from the risk of “bricking” the device. But the most common question is: “How long will it take for the firmware and why has the phone been hanging on one percent for 20 minutes?” The answer depends on a dozen factors – on the model Xiaomi (for example, Redmi Note 12 Pro).+ It takes longer to stitch than Poco. X3 NFC) Up to the firmware version and even the quality USB-cable.
In this article, we'll take a look at the real time frame of the Mi Flash firmware for 2026, write down each stage with timings, explain why the process might take longer, and give you a checklist to speed up. No abstract "10 to 60 minutes" -- just specific numbers for different scenarios, from fastboot firmware to EDL recovery.
1. Xiaomi’s standard firmware time via Mi Flash: What the user experience says
According to the 4PDA and XDA Developers forums, the average firmware time Xiaomi has through the Mi Flash Tool in 2026 is:
- 📱 Budget models (Redmi) 10A, Poco M4 Pro: 5-12 minutes (clean firmware without errors).
- 📱 Mid-segment (Redmi Note 11 Pro, Xiaomi 12 Lite): 12–20 minutes due to larger partitions.
- 📱 Flagships (Xiaomi 13 Ultra, Mix Fold 3): 20-30 minutes (complex firmware structure, additional checks).
- ⚡ Fastboot firmware (without data cleaning): 3-8 minutes.
- 🔄 Recovery through EDL (if the phone is "brick": up to 40 minutes.
Important: these figures are relevant for official MIUI firmware (stable or development) and LineageOS (Pixel Experience) firmware can be installed longer due to additional steps (unlocking the bootloader, patches).
2.Step-by-stage analysis: how long each step takes
Firmware through the Mi Flash Tool consists of 5 key steps, and below is their duration and what happens under the hood:
| Phase | Time (min) | What's going on? |
|---|---|---|
| 1. Connecting the device | 0.5–2 | Model definition, check the Qualcomm HS-USB QDLoader 9008 (for EDL) or Android Bootloader Interface (for fastboot). |
| 2. Loading firmware into the tool | 1–3 | Unpacking the.tgz or.zip archive, checking the checksums of images files. |
| Section cleaning (if selected) | 2–5 | Formatting userdata, cache, system (when selecting the "Clean All" option). |
| 4. Firmware recording | 5–25 | Rotating firmware sections: boot, recovery, modem, vendor, etc. |
| 5.Reboot | 1–3 | The first system start, application optimization (can take up to 10 minutes on weak models). |
⚠️ If the process has been stuck in the “Waiting for device” stage for longer than 5 minutes, check it out:
- 🔌 Cable (must support data transfer, not just charging).
- 🖥️ Port port USB (try USB 2.0 on the back of the PC).
- 🛠️ Drivers (install Mi Phone Manager for automatic installation).
3. Why Xiaomi’s firmware through Mi Flash is taking too long: top-5 cause
If your Xiaomi is stitching for longer than 30 minutes or getting stuck at one percent, one of these factors is the problem:
- Low speed. USB-Ports, ports. USB 3.0 (blue) often conflicts with firmware. USB 2.0 (black).
- Charging cables (like those from the iPhone kit) don’t work, you need the original Xiaomi or a certified USB-A to USB-C.
- The firmware for the Redmi Note 10 Pro (sweet) will not work for the Redmi Note 10 (mojito).
- Antivirus blocks Mi Flash. Disable Windows Defender or add MiFlash.exe to exceptions.
- PC hard drive problems: If the firmware is on an HDD rather than an SSD, the speed of reading files can slow down the process.

| Method | Time (min) | Pluses | Cons |
|---|---|---|---|
| Mi Flash (fastboot) | 5–30 | The official method supports all models | Requires PC, risk of errors when incorrect firmware |
| Recovery (via TWRP) | 10–25 | No need to unlock the bootloader for custom firmware | Not all official firmware supports installation through recovery |
| Oh.TA-update | 15–40 | Safe, does not require a PC | Long, no building. |
| EDL (Emergency mode) | 20–40 | Recovering the dead phones | Requires an authorized Xiaomi account for new models |
⚠️ Attention: Method EDL (Emergency Download Mode, which requires authorization through a Xiaomi account with a phone number tied from 2023, will be interrupted by an error without it. SLA Auth Error.
