Here’s a short instruction on how to flash or update modem files on your Xiaomi Mi4C device using TWRP recovery.
Flashing Modem in Xiaomi Mi4c using TWRP recovery
First download the MIUI ROM you want to extract modem file from. Modem file name is – NON-HLOS.bin (In custom ROMs this file is located in “firmware-update” folder).
- Download MODEM.zip
- Open this archive using WinRar.
- Copy previously downloaded and extracted modem file instead of empty NON-HLOS.bin inside of MODEM.zip archive. Compression method set to “Normal”.
- Now copy updated MODEM.zip into phone internal memory and flash it using TWRP recovery. Do not pay attention to the log files, if you see any errors, since the .zip is made on other device sources.
