Firmware Package for MediaTek MT6735P
Official firmware for the Lenovo Vibe C2 (K10a40) is packaged as a standard MediaTek scatter ROM. It contains the MT6735_Android_scatter.txt partition map alongside official partition binaries including preloader, boot, recovery, system, and userdata.
MT6735_Android_scatter.txt
In SP Flash Tool, click "Choose" next to Scatter-Loading File and select MT6735_Android_scatter.txt from the extracted firmware folder. Ensure the flashing mode is set to "Download Only".
Technician note on partition formatting: Always verify that the flashing dropdown menu in SP Flash Tool is set to "Download Only". Never select "Format All + Download", because complete formatting deletes the factory NVRAM partition. Wiping NVRAM deletes the phone IMEI numbers and network calibration, which will cause permanent SIM card signal failure.
