Ответ техподдержки Zebra, может кому то будет полезно
Good morning Sergey, thank you for contacting us. If a prelicensed device is missing a license, it can be usually fixed by the operating system reinstallation. However, MC3090 has been out of support since 2016, and the operating system files are not available anymore. Are you installing the 7.0 package, as it is the only prelicensed version, while the other packages are not prelicensed? If the Wavelink client does not seem to be licensed even with the 7.0 package, then there is nothing that could be done at this moment as the OS cannot be reinstalled. Please let me know if there is something else I can help you with
