Crucial Warning: Do not cross-flash firmware between "ugg" (Snapdragon 435, fingerprint sensor) and "ugglite" (Snapdragon 425, no fingerprint). Furthermore, when flashing Global firmware on a Chinese hardware unit (MDE6S) via Mi Flash Tool, NEVER select "clean all and lock". Locking the bootloader with mismatched regional software will trigger the fatal error: "This MIUI version can't be installed on this device". Always select "clean all" (flash_all.bat).

Frequently Asked Questions
The Redmi Note 5A Prime (ugg) features an octa-core Qualcomm Snapdragon 435 processor, a rear fingerprint scanner, 3GB/4GB RAM, and a 16 MP selfie camera with front flash. The base Redmi Note 5A (ugglite) uses a quad-core Snapdragon 425, has 2GB RAM, lacks a fingerprint sensor, and has a 5 MP front camera. Firmware packages are not interchangeable between ugg and ugglite.
This occurs during Qualcomm EDL 9008 flashing when the emergency COM port drops connection or driver signature checks interfere. Ensure you use a 64-bit Windows system, connect the microUSB cable to a rear motherboard USB 2.0 port, and test that Qualcomm HS-USB QDLoader 9008 is properly recognized in Windows Device Manager.
Xiaomi implements a regional bootloader lock check. If your hardware is the domestic China model (MDE6S) and you flash Global firmware (NDKMIXM) with the bootloader locked, the device detects the regional discrepancy and displays "This MIUI version can't be installed on this device". To prevent this, always select "clean all" (flash_all.bat) without locking.
If the phone does not respond to button combinations, remove the plastic back cover and locate the two gold EDL test points near the battery connector. Short the two pins together using metal tweezers while inserting the USB cable connected to your PC. This forces Qualcomm HS-USB QDLoader 9008 mode, allowing Mi Flash Tool to flash factory partition files.
