Hello everyone! I have two CRL meters recovered from a friend down. The first starts, passes a test page, and hangs showing: CELL. I think the software part has to be involved; because I did not find anything abnormal when opening it. A mini USB port on the side should probably match the programming, but I did not find the software. The second one does not work anymore. 2 legs of the MEGA 328P microcontroller are short-circuited. The microcontroller is easily found, but I do not have the software to program it, and on the map some points are soldering with a programmer but I do not know how to be able to regrogram it entirely. I attach the photos as attachments. Thanks for your help!!
