The question of how long software recovery will take is often raised when the smartphone has stuck to the logo or stopped responding to commands. Users faced with the need to use the MiFlash utility often panic if the process takes longer than they expected. The actual duration of the procedure depends on a variety of technical factors that cannot be ignored when planning a repair.
On average, a full firmware cycle takes 300 to 900 seconds, but the spread can be much wider, and the speed is directly affected by the type of cable you use, the version of the operating system you install, and the state of the device’s drive, and understanding these nuances will help you distinguish normal latency from a real error that requires intervention.
It's worth noting that the clean-all phase always takes longer than the usual update, and if you've chosen the save mode, it's faster, but the likelihood of software conflicts is higher, and let's take a closer look at what that time is and what's driving it.
Factors affecting the speed of data recording
The first and most important element of the chain is the physical connection between the computer and the smartphone. USB-Low-capacity ports (e.g, USB 2.0 instead of 3.0) can increase the data transfer time several times. MiFlash is sensitive to signal quality, and at the slightest interference, the communication protocol will try to resend packets, which significantly delays the procedure.
The second critical factor is the volume of the partition being streamed, which is a high volume of data being written when you switch from one version of Android to another (cross-grade) or when you change region (Global to China), and in such cases, the system has to reformat the logical structure of the partitions, which is a resource-intensive task for the memory controller.
- 🔌 Quality. USB-cable: the original cable provides stable transmission of currents and data, unlike cheap analogues.
- 💻 PC Resources: Background antivirus processes or a lack of RAM can block streaming.
- 📱 Status. NAND-Memory: A worn-out smartphone drive works slower, especially when writing large amounts of information.
💡
Use the ports. USB, located directly on the motherboard (back of the system unit), avoiding front panels and USB-hubs without additional power.
You can also not discount the loading of drivers. If the system does not have the correct Qualcomm or MediaTek drivers installed, the Windows operating system can spend extra seconds recognizing them every time the device reconnects in EDL mode. This creates the illusion of hanging, although in fact it is a preparatory stage.
Timekeeping of the firmware stages in MiFlash
The firmware process is not a monolithic action, it consists of several consecutive steps, each with its own time stamp. The first step is to initialize the connection and verify the integrity of the firmware image, at which point the utility reads the hash sums of files and compares them with reference values, which usually takes 10 to 30 seconds.
The main time is to write partitions directly. The firmware script sends commands to erase and write memory blocks. In the program log, you will see partition names such as boot, system, vendor and userdata. It is during the write stage that the userdata is often delayed, because this partition has the largest volume.
The final step involves checking checksums of recorded data and commanding to restart the device. If the process is delayed by more than 2 minutes at this stage, this may indicate that the smartphone is trying to perform the first boot with the reassembly of the app cache. In Fastboot mode, the smartphone usually just restarts, and you see the Mi or Android logo.
⚠️ Warning: If MiFlash status has changed to "flash success" but the phone doesn't restart for more than 3 minutes, try manually turning off and plugging the power cable.
Comparison of time costs for different models
The hardware platform is different, and the flagship Snapdragon models of the latest generation have faster UFS 3.1 or UFS 4.0 memory controllers, allowing you to complete the procedure much faster than on low-end devices with eMMC memory.
Below is a table showing the approximate firmware times for different device categories using USB 3.0 cable and high speed port. The data is averaged and can vary depending on the specific version of MIUI or HyperOS.
| Category of device | Type of memory | Approximate time (sec) | Features |
|---|---|---|---|
| Budget (Redmi A/Go) | eMMC 5.1 | 400 - 600 | Slow userdata recording |
| The middle segment (Redmi Note) | UFS 2.2 | 250 - 350 | Stable speed |
| Flagships (Xiaomi 13/14) | UFS 4.0 | 180 - 240 | High speed recording |
| Tablets (Pad 6) | UFS 3.1 | 300 - 450 | Larger sections |
It is important to note that switching from Fastboot ROM to Recovery ROM via MiFlash is not possible, the utility only works with images for bootloader mode. The time to unpack the firmware archive on the computer hard drive is also not counted in the table, but may take additional time if the disk is fragmented.
💡
The firmware speed depends on the generation of the storage protocol: UFS 4.0 is faster than the old eMMC standards.
Data Cleanup Modes and Their Impact on Timed
MiFlash offers three options: “Clean All”, “Save User Data” and “Clean All + Lock”; the choice of a specific mode drastically changes the duration of the operation; Save User Data skips the formatting step of the user partition, which saves up to 40% of the time, but leaves the risk of persisting system errors.
Clear All mode performs a complete cleanup of the userdata partition, which is the safest option for treating software failures, since it eliminates conflicts between the old file system and new system files, and it is at this stage that the timer can freeze at 200-300 seconds, creating a voltage for the user.
☑️ Pre-testing
The Clean All + Lock option includes all previous steps, plus locking the bootloader. Once the file is written, the utility sends a special command that changes the bootloader status to locked. This process is instantaneous, but requires successful completion of all previous steps. If the firmware is interrupted before that moment, the bootloader will remain unlocked.
Remember that when you choose to clean the phone completely, it will return to the “out of the box” state, which means that once turned on, you will need time to initially set up, log in to your Google account and Mi Account, which is also part of the overall recovery time of the device.
Typical errors and process hangs
The most common reason for delaying the process is a Flash Error or Missmatching image and device error. In the first case, the utility can not complete the recording due to a communication failure, in the second case, you try to install firmware from another model. Communication error often occurs at the 60-70% progress bar.
Sometimes it's stuck in the Sahara or Firehose phase, which indicates problems with low loader interaction, and in these cases, the timer can go on forever or stand still. USB-port, cable, or use of a PC with another operating system.
⚠️ Note: If MiFlash produces a Not enough space or similar error, do not proceed.This means that the selected firmware is not suitable for partition volume for your device, and forced writing will result in a brick".
What to do when you make a mistake 0xc0000005?
There are also situations where progress is 100%, but status is not changed to "Success." In this case, don't panic. Look at the log file. If the last line says Finish or Succeed, you can safely turn off the device. The visual interface of the program sometimes doesn't update correctly.
Process optimization and environment preparation
To ensure maximum speed and stability, it is recommended to close all resource-intensive applications on the computer. Browsers with a dozen tabs, torrents and video players can consume CPU interrupts, which is critical for synchronous data writing to the port.
Use the original file paths. MiFlash doesn't like long paths with Cyrillic characters. It's best to place a firmware folder at the root of the disk, like the one you see on the back, C:\xiaomi_rom\. This will eliminate coding errors when reading batch scripts.
- 🗑️ Disk Cleanup: Make sure that the system drive has at least 10GB of free space for temporary files.
- 🔋 Power laptop: when working with a laptop be sure to connect it to the network, so that energy saving does not reduce the voltage on the computer USB-port.
- 🚫 Disabling antivirus: the security software can count the entry in the boot sector suspicious activity.
If you are using a virtual machine for firmware, make sure that USB-The filters are configured correctly and the device is drawn directly, without emulation. Virtualization always adds latency, which can lead to connection timeout during critical recording phases.
💡
To speed up the search for drivers, use the command line with administrator rights and the pnputil command to force the installation of.inf files before running MiFlash.
