1. Introduction The LG K52 is a budget Android device powered by the MediaTek Helio P22 (MT6762) chipset. In standard operational scenarios, users rely on software buttons or ADB commands to enter Download Mode or Recovery. However, when the device is bricked, bootlooping, or has a forgotten Google account (FRP lock), software methods become inaccessible. The Test Point (TP) method provides a hardware-level backdoor to force the device into a low-level download state, allowing specialized tools (Octopus, UnlockTool, Medusa Pro) to communicate with the device. 2. Purpose of a Test Point A test point is a specific pair of exposed copper pads on the device’s main PCB. Shorting these points forces the CPU to bypass the normal boot sequence and enter BootROM or Preloader Mode (in MediaTek devices, often recognized as "MediaTek USB Port" or "Preloader" in Device Manager).
The plans are in metric units, except for drill and shaft sizes, which are in imperial units.
You can generate plans in imperial units simply by changing the units to "imperial" in SketchUp under
"model info", but the units will not work out to even numbers like they do in metric.
Please also consider these important safety notes
A French language version of the 2010 plans is also available.
After buying the plans you can download the latest version and the 2010 French version.
