USB upgrade
1. After booting up, insert USB drive and automatically upgrade upon detecting upgrade file.
2. An upgrade package completes the upgrade of all Soundbar modules.
3. After upgrade is triggered, VFD displays UPG01-UPG99 as the progress display, with each grid time being relatively uniform and the numbers continuously jumping. After upgrade is successful, UPGOK will be displayed and soundbar will automatically restart. If upgrade fails, it displays UPG FAIL and then automatically restarts. Reinserting and unplugging the USB drive will restart upgrade to avoid cyclic upgrades.
4. The format of the released compressed package is "TS8212 20210106 VER11_11_04_07_05_05_06.zip", where latter part is the software version number searched on Bar. The official upgrade file "TS8212.UPG" is only created after decompression, and there are explanatory documents describing the small version numbers of each module, which is convenient for checking whether upgrade is complete after upgrading.
5. If there is an abnormal power outage during upgrade process, simply power on and restart, and upgrade will resume.
6. If subwoofer is not connected and needs to be upgraded, it will prompt that the upgrade has failed and return to the original software.
