Huawei JAT-L41 Test Point

What is a JAT-L41 test point?

Why do the Huawei JAT-L41 Test Point operation? The test point is the emergency software installation mode. We may not always be able to fix software problems over a USB connection. With the test point, we can switch the phone directly to software mode and we can switch the phone directly to software mode and we can install rom on the phone. Then unlock the FRP without having a problem with the bootloader lock.

How to test point?

Before doing this, open the back cover of the phone and touch the test points with tweezers as shown in the photo below, and at the same time plug in the USB cable. After the test point, the phone will be connected in “mtk preloader” mode. The phone is now ready to use in “mtk preloader” mode.
