Ground (multiple points near the eMMC for better stability). Technical Recommendations
Using a magnifying lamp (minimum 10x):
: Look for the grouping of tiny test points or resistors next to the eMMC.
After reverse engineering the LG K41s mainboard (disassembly code: LG-Q630_MB_V1.0), we have identified an near the EMI shield cutout close to the CPU. These points are larger, labelled, and offer a cleaner signal.
You can read, but you cannot write to the user area. With this "better" pinout + CLK resistor: Full read/write, including boot partitions.
