How to Easily Get S-Off on HTC One M8?

One of the best Android-based mobile devices is none other than the HTC One M8. It is equipped with high-end specifications and features that complement the superior performance of the device that you make any advanced Android user more than happy to use it. However, in order to take full advantage of this Android device, you should consider the HTC One M8 S-Off procedure to "release" its internal working so that you can perform other customizations and operations.

The term "S-Off" may put you into a whirlwind of confusion and intimidation but it is really easy to get and work with.

Part 1: What is S-Off?

By default, HTC equips their devices with a security protocol that ranges between S-ON and S-OFF. The security protocol place a flag on the device's radio that will check the signature images of any firmware before it will "clear" it for installation on your device's system memory. Therefore, you will not be able to customise any parts of your device: ROMs, splash images, recovery etc; it will also limit access to its NAND flash memory. 

By activating S-OFF, the signature protocol is bypassed so that you can maximise customisation on your Android device. HTC M8 S-OFF reduces the access limitation to the device's NAND flash memory so that all partitions, including "/system", are on write mode while Android is being booted.

Part 2: Back Up Data Before Getting S-Off

Before enabling S-OFF HTC One M8, it is best to back up data on your device. You know, in case your customisation endeavours go sour.

Backing up your device is a relatively easy task, especially if you have the help from dr.fone Toolkit for Android - Data Backup & Restore. It is a flexible Android backup and restores software that allows users to backs up and restores different types of data including calendar, call history, gallery, video, messages, contacts, audio, applications and even application data from rooted devices that you can preview and selectively export. It supports more than 8000 Android devices including HTC.
