SP Flash Tool is a portable software can be used from portable storage devices such as USB flash drives or external hard drives whose function is to update firmware, format, readback, and test the internal memory device using a MediaTek system-on-a-chip (SoC).

This experience occurred when I tried repairing the Redmi Note 4 Mediatek (Nickel) brick. Insert the firmware into the SP Flash Tool, and checked all partitions. However, the cust.img file has been replaced with a smaller size than the original. I tried twice with Download Only and Firmware Upgrade. Both failed, and a BROM ERROR STATUS DA EXCEED MAX NUM message appeared.

What should I do if I get a notification Failed to Get PMT Info in the SP Flash Tool? That problem often occurs when flashing Mediatek phones.
