If you want to play with Huawei devices, you must have some basic boot pins, tools, and knowledge. Earlier, we have unlocked Huawei E5573 routers of different countries with boot pin and ground. Boot pin also helps to recover the dead modems/routers.
Today, we have a big collection of various device boot pins. Some are live images of the device, while some are just diagrams. If you have the device and want to help us, send me a live image to replace the diagram.
Sometimes, Boot Pin helps unlock the device, whereas sometimes it also unlocks stubborn modems.
