Unlock ZTE Crescent - Orange SanFrancisco2 or Tmobile Vivacity

By df
First of All Full Credits to Team in Modaco . Please find full credit and details at:  Modaco ZTE Crescent Unlock Thread . I've just rewritten the steps for simplification purposes only.

If you are starter, there are two parts to the section:  (a) Unlocking ..   &   (b) Installing ROM

[ad#ad-3]

(a)Unlocking

Pre-requisites. Please install below softwares into your Windows PC.

  • Unzip /Archive Software. I prefer 7zip.

  • Either (Android SDK)  OR else (Install ADB + Drivers)

  • QPST Tools -  Download Here

  • Unlock File for  Vivacity   (Unlock_Vivacity.zip)  OR  San Francisco2 (========). BEWARE:  Using incorrect will BRICK your device. Extract it using 7zip into a folder. (eg:Vivacity_Unlock_Directory)

  • If you want a new ROM installed, download the ROM. Copy this ROM into your Phone's SD card. (in Phone's SD Card create a folder  "ROMs" and put the rom inside that for easy identification. See "Install ROM" section below)


Now Let's Start the Action..


  1. First Check if your Phone is already Unlocked, sometimes you never Know!! :)

  2. Enable USB Debugging in your Phone (Settings > Applications > Development > USB Debugging)

  3. Connect your phone to the PC. In most cases, Windows will detect/install the required Drivers. Wait for some time and ensure everything is Green (Windows installing all drivers correctly)

  4. Turn the Phone OFF and disconnect from PC.

  5. Press and hold the Volume Down and power buttons together. This SHOULD bring you to a screen saying FTM. (Sometimes First Try will log you into Android. Shut down again, remove the battery, wait 10s, put battery again, RETRY vol down + Power Button .. repeat until you get FTM ).

  6. Connect back your Phone to PC to the same USB port which you connected before. Since you have QPST installed as a pre-requisite. Find "QPST Configuration" from START MENU in your PC, Click on "Ports" and then the "Add Port" button. (Mine was configured at COM13).            Now Press OK.

  7. Without Closing "QPST Configuration" ,  open (Start Clients -> "Software Download")  

  8. Click "Backup" on the utility and choose where to save the "QCN" File.  Save this into your PC at a safe location.  

  9. Locate the saved QCN file and check the size of it. Ensure that its more than 10KB. if NOT try again the previous steps.

  10. Navigate into the Unlock file folder. (eg... Vivacity_Unlock_Directory ) and  run "download.exe". (BEWARE: Ensure that you are running the correct unlock file. If you use Vivacity unlock file for OSF, it will brick the phone permanently) 

  11. If all goes Well, a pop-up window will come with  a "READY" green button below "START ".  Click START

  12. Should take atleast 2 mins.. If everything goes well, you should see a "PASS" Screen. 

  13. Go back to the "QPST Configuration" -> "Software Download" utility and click "Restore".  Find the .qcn file you saved and restore it. 

  14. Once its successful, close the "QPST Configuration" utility.

  15. Phone should be unlocked by now.  You can remove the phone from PC.

  16. Install ClockWork Recovery Mod (CWM). Steps shown here.

  17. If you don't have a ROM ready, it will be still stuck in screen with some boot.  Something like below Screenshot.

(b) Installing new ROM

Pre-requisites.

  • Ensure you have a suitable ROM.  As of 2012-07-25 I recommend using "CyanogenMod 9 for the ZTE Crescent". Please read the Pro's and Con's before you Decide.  (courtesy to Dazzozo and rest of the team for all the efforts)

  • ROM as it is (DO NOT unzip) , copy this into your Phone's micro SD card. (Hope you create a "ROMs" folder within SD card).  (If you can't copy via phone, take the SD card out and put into your PC and do this action)

  • Optional - Download items like Gapps, Boot animations etc.. , download them and put them into the "ROMs" folder.



  1. In your Phone, From the last step of Unlocking, navigate using Volume Up/Down key. Use Menu button for Enter and Back Button for going back.

  2. Select "Install Zip from SD Card".  Navigate down using volume buttons and Select "ROMs" and then select the  above selected ROM.

  3. This should install the ROM. It will take atleast 2 mins to install the ROM

  4. Install Gapps in similar manner

  5. Go back and reboot the system. The first reboot will take time.. say 5mins..  (don't fear if its stuck in the boot logo for long.. that's just first time only)

  6. You should be good by now.. Just make some changes  into your Android ICS ...
