CID: Carrier Id - commonly used in the form `CID-Unlocking`. If you purchase your phone (example) from Qtek (Qtek is the 'carrier'), your phone will only accept Qtek ROMs (the carrier's ROMs). If you want to flash ROMs from other carrier, you'll need to CID-unlock your phone, so that your phone will accept other ROMs.
Copied from Forum:get cid information
If you want to know if your device is CID locked or not:
2. disable active sync connection
3. connect USB cable and start mtty console.
4. perform set 32 command in mtty console. in a response you will see g_cKeyCardSecurityLevel = 00 or g_cKeyCardSecurityLevel = FF
00 - stands for unlocked FF - locked
rem: if you use USPL (USPL is installed on your device), then set 32 command will always report g_cKeyCardSecurityLevel = 00, although on a reality device remains locked. USPL just bypass CID check.
Please before flashing, update your rom with the latest official one, then with one of following SPLs
