HTC functions and descriptions

What kind of HTC functions do we (ChimeraTool) have and what are they used for?

 

Get Info:Retrieve generic, basic information about the device such as serial number, IMIE, model number, etc.

Repair IMEI: The IMEI or MEID number for your mobile phone acts as a unique identifier for that device. No two devices will have the same IMEI or MEID, which makes it a very useful tool for tracking lost or stolen cell phones. You can quickly retrieve and record your phone's IMEI or MEID number in a variety of different ways, depending on your device.

The IMEI number is used by a GSM network to identify valid devices and therefore can be used for stopping a stolen phone from accessing that network. For example, if a mobile phone is stolen, the owner can call their network provider and instruct them to blacklist the phone using its IMEI number. This renders the phone useless on that network and sometimes other networks too, whether or not the phone's subscriber identity module (SIM) is changed.

The Repair IMEI function is for restoration of the original IMEI of a device.

Change CID: With this function you can change an HTC device’s operator (or regional) customisations. This will remove all preloaded configuration, internet settings, etc.

Unlock / Relock Bootloader: A locked bootloader is one that will only boot an OS that it "approves" of. This may mean that device's boot partition has an approved digital signature, or the carrier ID (CID) hard-coded into the OS matches a value hard-coded into the bootloader itself.

For devices with a locked bootloader, booting an unsanctioned OS requires the device's owner to first unlock the bootloader. Unlocking the bootloader sometimes voids the device's warranty. Procedures vary typically by manufacturer.

S-ON/OFF: S-ON/OFF is a security function, usually implemented in the HBOOT or RADIO , which, among other things, prevents the flashing of unsigned firmware components (eg HBOOT, RADIO, boot or system), as well as the use of some functions of the Fastboot.

By deactivating this security check (generally known as S-OFF ), the user is given the opportunity to use functions which are denied to him by the system. Since switching off requires an intervention in the boot loader, which changes the value of the security flag, there is a certain risk. Due to improper handling of different possibilities, or unclear and insecure tools, it can in the worst case, brick a device. 

However, when the security level is set to S-OFF(Security-ON/Security-OFF), the signature check is bypassed, allowing a user to upload custom firmware images, unsigned boot, recovery, splash and HBOOT images, as well as official firmware that has been modified – enabling the maximum customisation abilities of the HTC Android devices.

Read NCK: Unstructured Supplementary Service Data (USSD), sometimes known as "quick codes" or "feature codes", is an extra-UI protocol, which allows device owners to access hidden features. The USSD protocol allows you to access hidden features from your smartphone's dialler.

These publicly available backchannels allow users to directly communicate with their service provider's computers and/or access back-end features in their device. They are accessed by inputting them into the phone's dialler (the screen you use to start a phone call) and usually begin and end with the * or # keys with a sequence of numbers in between.

The read codes feature gets you some of these USSD codes that are available for your device.

Remove FRP lock: Factory Reset Protection (FRP) is automatically activated in every Android device during the Google account setup process. Once FRP is enabled and someone wants to reset the device using the Backup & Reset feature, then the system would require the device's security PIN to protect the owner's data and files.

While it’s a good thing in general, it can become a problem if you sell, trade, or even return a new phone without factory resetting it. If you've forgotten to turn off FRP and send a phone to someone else, you'll likely need to help them get it set up. This means giving them access to your Google account password or to have the device returned so you can do it yourself.

The FRP remove function helps the shops and owners to enable the Factory Reset function again on their devices.

Network Factory Reset:Normally, Network Factory Reset resets all network related settings to the device’s factory state, before it was configured by any company or carrier. This can repair devices that don’t connect to networks that are compatible by factory state or fix signal/reception related issues.
