Method 2: Fastboot Firmware (for power users)
If Recovery resets don't work or the phone doesn't turn on at all, the next step is to run the Fastboot mode, which requires a computer and special utilities, but can be restored to work even in cases of serious failure.
First, download the official firmware for Redmi 7A (codename pine) from MIUI Downloads. Choose the Fastboot version (file with the extension.tgz or.zip).
- π§ Mi Flash Tool (official utility from Xiaomi)
- π₯οΈ Drivers. ADB/Fastboot (You can download it through Mi. PC Suite)

Note: EDL firmware is officially blocked by Xiaomi for most devices without an authorized account. However, for the Redmi 7A (2019 model), you can still find workarounds, for example, through boxes like UFi Box or EasyJTAG. If you do not have experience with such tools, you should contact the service center.
For an independent attempt, you will need:
- π Cable EDL (special USB-cable with a circuit on the contacts Test Point)
- π» Mi Flash Pro or QFil (for firmware via Qualcomm)
- π Firmware file in.mbn format (can be extracted from the official Fastboot package)
