How to Flash via Fastboot (Mi Flash Tool)
- Unlock your bootloader using the official Mi Unlock tool. This is an essential first step.
- Extract the downloaded .tgz firmware file to a folder on your PC.
- Open Mi Flash Tool. Click Select and choose the extracted ROM folder.
- With your phone powered off, boot into Fastboot mode (Hold Volume Down + Power). Connect it to the PC.
- In Mi Flash Tool, choose the clean all option. NEVER select “clean all and lock” if you are flashing a different region’s ROM or a custom ROM, as it may brick your device.
- Click Flash and wait for the process to complete. The first boot may take 5-10 minutes.
FAQs
Q1. Can I flash the Global Android 7.1 ROM on a Chinese model Redmi 4A?
Yes, but it is a major cross-flash between different Android versions and carries a significant risk of soft-brick or baseband issues. It is highly recommended to only flash the Global ROM if your device was originally a global model. For Chinese models, stick to the China ROM for maximum stability.
Q2. Why is my touchscreen sometimes unresponsive after waking the device?
This is a common hardware issue on aging Redmi 4A devices, often related to a faulty digitizer or a loose display connector. A software reflash can sometimes help by clearing system glitches, but if the problem persists, it is likely a hardware fault requiring a display replacement.
Q3. What is the latest Android version available for rolex?
Officially, the Global variant stopped at Android 7.1 (Nougat) and the China variant at Android 6.0 (Marshmallow). However, thanks to a very active development community, you can install custom ROMs like Pixel Experience or LineageOS that bring Android 10 or even Android 11 to this device, greatly extending its useful life.
Q4. My device is stuck in a bootloop and can’t enter Fastboot mode. What can I do?
If your device is completely unresponsive, you can use EDL (Emergency Download) mode with Mi Flash Tool. For the Redmi 4A, entering EDL usually requires opening the back cover and shorting two specific test points on the motherboard while connecting the USB cable. This will allow Mi Flash Tool to detect the phone in EDL mode for recovery.
Troubleshooting (Redmi 4A-Specific)
- “Antirollback check error” in Mi Flash Tool: The Redmi 4A has Anti-Rollback (ARB) protection. This error means you are trying to flash a ROM with an older security patch level than the one installed. You must flash a ROM with the same or a higher version number.
- Baseband/IMEI unknown after cross-flashing: Flashing between the Android 6.0 and 7.1 ROMs can corrupt the modem firmware. To fix, flash the stock ROM that originally came with your device. If the IMEI is permanently lost, you may need to rewrite it using Qualcomm’s EFS tools, which is a complex process.
- Mi Flash Tool not detecting device in Fastboot: This is usually a driver issue. Install the latest ADB/fastboot drivers and try a different USB cable and port (preferably USB 2.0). Check device detection with
fastboot devicesin the command prompt. - Phone boots directly to Fastboot mode: This indicates a corrupted
boot.imgor that the device has been previously unlocked and the system partition is damaged. Flash the complete stock ROM using the “clean all” option in Mi Flash Tool to restore all partitions. - Flashing TWRP fails or doesn’t stick: After flashing TWRP via fastboot (
fastboot flash recovery twrp.img), immediately boot into it usingfastboot boot twrp.img. Once in TWRP, go to **Settings** and check **”Keep Read Only“** to prevent the stock ROM from overwriting the recovery on reboot.
