Hello, dear Forum members! The problem with this tracker is the ban on changing the server. When sending an SMS message with the server settings, the gps tracker sends an error message. Alas, it is programmed from the factory so that only their server is used. There is a locked and unlocked tracker (which lends itself to SMS commands). There is an idea to connect via tx rx and transfer the firmware from one to the second. There is an rdk 8955L processor on board, which is sealed with a protective cover. I am attaching a photo. The board has pins + - dp rx1 rx gnd tx tx1 off rest pwk gtx grx.
There are 2 identical devices in the photo, but one is already without a lid (unsealed.) I am interested in software and a programmer for reading the firmware. I tried using usb UART and Luatools_v2 software. To no avail. p.s gnd and pwk contacts were connected with a 1k resistor. p.p.s even more interesting are the necessary contacts for firmware.
