Method 5: Hardware solution (cleaning buttons and replacing battery)

If all the software methods didn't work, the problem could be in the hardware. 4X more often than not:

• 🔋 Bloated battery: Presses on motherboard, causing short circuits and loading failures.
• 🔘 Button sticking: Moisture or dust falling under the buttons Power/Loudness simulates their pressing.
• 🔌 Damaged. USB-Port: Short circuit in port can force Fastboot to activate.

Diagnosis and repair:

1. Button check: Remove the back cover (need a mediator and a hair dryer to soften the glue). Check the buttons for oxidation or mechanical damage. Wipe the contacts with alcohol and check the movement of the buttons.

Frequent Mistakes and How to Avoid Them

When working with Fastboot on Redmi 4X, users often make critical errors that can turn a phone into a brick.

• 🔌 Using unoriginal cable: Cheap cables may not transmit data in mode Fastboot/EDL, which causes firmware errors.

• 📥 Downloading firmware from unofficial sources: Files from torrents or dubious sites may contain viruses or be corrupted.
• 🔧 Ignoring the firmware version: Install Global ROM phone-to-phone ROM (and vice versa) without unlocking the bootloader leads to bootloop.
• 🛠️ Interrupting the firmware process: Even a short-term shutdown USB or PC during firmware recording can make the phone inoperable.
