I understand you're looking for information about a test point for the Nokia TA-1452 (a Nokia C-series or G-series device, often used for unlocking, flashing, or bypassing FRP — Factory Reset Protection).
However, I can’t provide a full "solid feature" breakdown of that specific test point here, because:
Because Nokia locks the bootloader, the phone will reject SP Flash Tool's handshake.
The Nokia TA-1452 (commonly known as the Nokia 110 4G (2023) or similar entry-level models) is a MediaTek (MTK) based device. In scenarios where the phone is bricked, hangs on the logo, or requires a firmware flash but the standard "Volume Down" method fails, you must use the Test Point method to put the device into EDL (Emergency Download) Mode or BROM Mode.
This guide explains what the Test Point is and how to locate it.
The Test Point method is a powerful tool, but it comes with significant caveats. Technically, it is unforgiving. Shorting the wrong two pins can cause a short circuit, permanently destroying the phone. It requires a steady hand, a magnifier, and a detailed board schematic. Furthermore, it bypasses all user-level security. This leads directly to the ethical dimension.
Legitimate uses include: repairing a device that has been bricked by an official update, recovering data from a malfunctioning phone for forensic investigation (with legal authority), or restoring a forgotten lock code on one’s own property.
Illegitimate uses are equally apparent. Because the Test Point UPD grants full read/write access to the phone’s raw memory, it can be used to:
Therefore, the knowledge of the TA-1452’s test point location is a double-edged sword. Most official service centers will not share this information publicly, while underground repair forums and YouTube channels trade it freely.
The exact location of the test point is not documented in Nokia’s public service manuals, but reverse engineering has revealed the standard Unisoc layout for this model.
Procedure to find the TP:
For the TA-1452 (Unisoc SC9863A or SC7731e variant):
Visual Suggestion: It is highly recommended to search for a "Nokia TA-1452 TP point image" on GSM forums (like GSM-Forum or XDA) as motherboard revisions differ (V1.0 vs V2.0).
Before attempting to find the test point, safety is crucial.
