Do you have an HTC phone and wish to alter partitions on your phone? Is the security feature disturbing you from doing this? This article will deal with HTC S-OFF, which lets you turn off this security protocol. As a part of this process, you will be required to learn about the HTC bootloader, which is covered in the article. Read the article completely to have a better insight on this topic.
HTC SOFF là gì?
Generally, all the devices have the S-ON security protocol, for which it places a flag on the Radio partition while being shipped to the public. In other words, the security flag of the HTC phone is turned on by default. You can turn off this flag on your HTC phone. Here’s how to do it:
- It is stored on the device’s radio and turning it off can allow you to write to the system memory.
- It hinders you from using any custom ROMs, splash images, recovery, etc., on your HTC android phone.
- It also prevents you from accessing the NAND flash memory and restricts you from making permanent changes to the NAND partitions on the device.
- The NAND partition includes the Boot partition, the recovery partition, the Radio, the System partition, etc.
- The changes you make on the HTC phone with the S-ON can be reversed to normal by simply rebooting the phone.
- S-OFF doesn’t give you the flexibility to revert to the functions of your phone upon a reboot. You can know if the phone is S-ON or S-OFF or if the flag is on or off, from the text on the top of the notification.
