Archive for the Openbox S10 receiver marked CMT 1213, which most likely points to a December 2013 build or a specific firmware revision, though the name is not explicit, packed as a 1.69 MB RAR file. The name also carries a website prefix. Openbox receivers are usually updated through USB or serial loaders, and a corrupted box can be revived with the correct image. Check the contents, confirm the S10 hardware variant, and keep the current firmware as a backup before flashing.
