Common questions
Q: What is the difference between local upgrade and online upgrade?
A: There is no difference between online upgrade and local upgrade. The failure rate of online upgrade is low, and it is completely safe for TV to choose online upgrade. However, when the home network speed is not good or there is no way to connect to the network, the local upgrade is selected.

Q: Is the upgrade package universal? Do you have to compare your model and movement?
A: Due to the difference in TV hardware, there is definitely a slight difference in the system package of each TV. If you use the wrong upgrade package will lead to the TV's black screen and crash and so on. Therefore, when choosing a local upgrade, you must pay attention to your own TV model and movement.

Q: What if the TV does not detect the upgrade package in the USB flash drive?
A: First confirm if you have the right upgrade package, and then try to replace the U disk. Upgrade U disk must be FAT32 format.
