Samsung jigs have existed for quite some time, and have a number of uses. The most popular of which is the Download Mode jig, which is configured in such a way that, when plugged into a Samsung phone, it forces the phone into Download Mode. This is a popular way to fix certain types of bricked devices, when other methods fail to power them on.
However, this is not all a jig is capable of doing. In fact, if a jig is made the proper way, it is capable of a very large number of things. There are no jigs that are commercially available that users can reproduce at home—not yet, anyway. XDA Recognized Developer E:V:A has begun a project to create a modified version of the Samsung Anyway Jig. What might that entail? Says E:V:A:
One particular such device, provided by Samsung, has been used for years to program, customize, repair, debug and unbrick essentially all available Samsung phones. This blue box is called the “Samsung Anyway Jig”, and somehow Samsung has managed to hide it from public scrutiny and analysis, which have elevated this device to an almost mythical status. At least for the common person wishing to repair or modify his phone.
In most cases, talking about a piece of hardware like this is much like the perfect phone, wherein such a magnificent device doesn’t actuallyexist. In contrast, the Samsung Anyway Jig does actually exist. It’s hard to find any documentation about it, but E:V:A dug up and shared pretty much all there is to know with one thing in mind: reproduction. If such a device can be modernized and reproduced, it could spell the end for a large number of bricks, along with pretty much any other hardware issue that anyone might have with any Samsung device. There has been development like this before, such as the hackdock demonstrated in this video by XDA Elite Recognized Developer AdamOutler.
