Thanks for sending the TV file ARIELLI LED-3219 HD but I wanted it in a format IMG (no bin format) to get it on TV with a USB stick.
TV chassis is the HK-T.RT2957P61

Unzip and save to an empty flash drive. Turn on the flash drive in the TV, then you turn on the power plug. Do not turn off while the upgrade is in progress.
