You can block the download link by modifying the TV or box's hosts file.
step:
1, install re file browser, and open.
2, enter the directory /etc
3, use the remote control "mount read and write"
4, select the hosts file, pop open mode, select "text editor"
5, edit the hosts file, enter "127.0.0.1 osfota.cdn.aliyun.com" inside.
6, editing is completed, select the "Save Changes" in the upper right corner
The second method: for users without root
1. You can manually set DNS or turn on router filtering.
Manually set up DNS:
a. Tap to enter settings.
b. Click Network to enter the wireless network.
c. Find the currently connected WIFI and press OK to enter the settings. Change the IP acquisition mode to "Manual".
d. Change the DNS to 182.92.190.89. After setting up, we choose this wifi, will not be prompted to upgrade, does not affect the normal use.
2. Set up router filtering
a. First enter the router's management interface and find the firewall settings. Then turn on the firewall and enable domain filtering.
b. Enter the domain name that needs to be filtered (masked) and the time that the screening was turned on.
The domain names are as follows:
Osupdateservice. yunos. com
Osfota. cdn. aliyun. com
Add these two domain names to the block list and save them.
c. Restart the router and device.
Finally, the simplest method:
Restore factory settings offline
Install the sofa butler: http://, download all the software that you want to install.
During the process, the system will prompt to upgrade and download the installation file.
Solution: Power off immediately after checking the file and restart it! Then the system will lose the downloaded update file because there is no place to store it.
The software is used to fill the system, the purpose is to allow the system to be upgraded, no place to put the installation files! It is that simple, all smart TVs, boxes are universal!
The main function of the Solar Charge Controller is to manage the charging and discharging process between the Solar Panel and the battery in the solar power generation system. Its main function is to protect the battery from overcharge and over-discharge damage, ensure battery charging efficiency, and stabilize the operation of the solar power generation system.
Main effect:
Charge control: The solar charge controller controls the charging process by monitoring the voltage and current generated by the solar panel to ensure that the battery is charged at the appropriate voltage and current to extend the battery life.
Overcharge protection: The solar charge controller can monitor the charging status of the battery, and when the battery is fully charged, it will automatically stop charging to avoid battery damage caused by overcharging.
Over-discharge protection: The solar charge controller can monitor the discharge state of the battery. When the battery power is lower than a certain level, it will automatically stop discharging to avoid battery damage caused by over-discharge.
Differences from other charge controllers:
The solar charge controller is a charge controller specially designed for solar power generation systems, the main differences are as follows:
Applicable Energy: The solar charge controller is suitable for solar power generation systems, mainly used to manage the charging and discharging process between solar panels and batteries. While other charge controllers may be suitable for different energy generation systems, such as wind energy, hydro energy, etc.
Charging characteristics: The solar charge controller is optimized for the characteristics of the solar panel, and can control the charging process according to the output power and voltage characteristics of the solar panel. Other charge controllers may be optimized for different types of energy generation characteristics.
Protection function: Solar charge controllers usually have overcharge protection and over-discharge protection functions to ensure the safe charging and discharging of batteries. Other charge controllers may have different protection functions, depending on the needs of the application scenario.
Overall, the main role of the solar charge controller is to manage the charging and discharging process in the solar power generation system, protect the battery from damage, and stabilize the system's operation. Compared with other charge controllers, it is optimized for the characteristics of solar power generation systems and has unique functions such as overcharge protection and over-discharge protection to meet the needs of solar power generation systems.
