Yes. Standard flash tool procedures, especially when changing partition maps or clearing out system directories via Bootrom mode, wipe out user storage blocks entirely.
: Always disconnect the battery flex cable before shorting any points on the motherboard to prevent a short circuit that could permanently damage the SOC.
Reference specific schematics or trusted hardware image archives via programming platforms like GSM Sanjoy to precisely verify the location of the pin for this exact variant before applying tweezers. Step 3: Connect to the PC in Bootrom Mode jmmal10 test point upd

A hardware test point is a small, exposed copper contact on a device's logic board (motherboard). Shorting this specific pin to the ground line (such as a metal shield) during the boot cycle forces the system-on-chip (SoC) to halt its normal boot sequence. Instead of launching the Android OS, it triggers its lowest-level USB flashing interface—MediaTek Bootrom Mode.

: Do not yank the back cover away immediately. Slowly lift it to expose the fingerprint scanner flex ribbon cable connected to the motherboard. Safely disconnect it.
is a specific physical contact point on the device's motherboard that, when shorted to the ground, forces the phone into a specialized hardware mode—typically MTK Boot ROM (BROM) when shorted to the ground
Ensure the phone's battery has at least a 30% charge to ensure stable data line voltages.
