Jelly Bean for HTC One V: Experimental CM10 ROM Available, Based on Android 4.1


Move aside One S and One X, it’s time for the youngest of the One series to shine. A Jelly Bean Android 4.1 ROM has been released for the HTC One V, bringing it up to date to the latest version of Android. It still remains to be seen if HTC will officially update the One V to Android 4.1, but even if they don’t, custom ROMs are always there to do the job.

HTC Recognized Contributor jmztaylor has released an experimental CyanogenMod 10 (CM10) ROM based on Jelly Bean for the One V. CM10 features fast performance and extended customization possibilities, along with Jelly Bean features such as a smooth interface, improved and actionable notifications, Google’s intelligent software assistant, advanced voice recognition, offline voice typing, faster browser, and more.

NOTE: This rom is only and only for CDMA HTC One V (PrimoC), DO NOT try on GSM HTC One V (Primo).

The ROM is currently in the experimental stages so there might be a few bugs and issues in the ROM. There are a few things that do not work yet (as of 11 Aug), listed below (quoted from developer):

Broken: (In order of importance)
-LCD Backlight never turns off

So, continue reading to find out how you can get a taste of Jelly Bean with CM10 on your HTC One V.


This guide is applicable only for HTC One V. DO NOT try this on any other device.


The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to your device, we won’t be held liable.

How to Install CM10 on HTC One V


  1. This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
    NOTE: Don’t forget to at least make a backup of your APN settings, which you can restore later if your data connection does not work after installing the ROM. Use the backup guide to find out how.
  2. Unlock the bootloader on your One V by following the bootloader unlocking guide → here. Keep in mind that this will void your phone’s warranty.
  3. Install ClockworkMod (CWM) recovery by following the guide → here.
  4. Download the latest version of the ROM from the development page.
  5. Download the Google Apps package. This will install apps like Play Store, Gmail, etc. which are not present in the ROM by default.
    Download Gapps  |  Filename:
  6. Copy the two zip files downloaded in step 4 and 5 to the SD card on the phone.
  7. [Backup Current ROM] To be able to return to your current ROM from CM10, make a backup of it (this is different than the backup taken in step 1 as this backs up the whole ROM).
    1. Turn off your phone. Boot into the bootloader mode first by holding the Volume Down button and then pressing power key to turn on device. Then, select RECOVERY from there using the volume buttons to navigate and power button to select to boot into recovery.
      In recovery, use volume button to scroll up/down and the power button to select.
    2. Then, to perform a backup, select Backup and Restore –> On the next screen, select Backup again. Go back to main recovery menu after backup is complete, then select reboot system now to reboot the phone.
  8. Download the jbboot.img file from the download link below, which is required to be flashed along with the ROM.

  9. Download fastboot.
    Download Fastboot  |  Filename:
  10. Extract the file to the C:\ drive on your computer to get a folder named Fastboot with four files inside it.
  11. Copy the jbboot.img file downloaded in step 8 to the Fastboot folder on C:\. You will now have 5 files inside it.
  12. Switch off the phone. Enter fastboot mode. For that, boot into the bootloader mode first by holding the Volume Down button and then pressing power key. Then, select fastboot mode from there using the volume buttons to navigate and power button to select. Then connect your phone to the computer once you are in fastboot mode.
  13. Open Command Prompt on your computer from Start » All Programs » Accessories.
  14. Now, type the following commands in command prompt to flash the kernel, pressing Enter after each command.
    1. cd c:\Fastboot
    2. fastboot devices (this is to ensure the phone gets detected. A string of numbers and letters should appear if the phone is properly detected. Else, make sure you have the phone drivers properly installed)
    3. fastboot flash boot jbboot.img
  15. After the kernel is flashed, you’ll get a finished/OKAY message in command prompt.
  16. Disconnect your phone from the PC.
  17. Now, on your phone select ‘HBOOT’ using the Power button. And then select ‘RECOVERY’ to boot into recovery mode.
    Use volume buttons to scroll up and down and the power button to select options in bootloader menu and recovery.
  18. Select wipe data/factory reset, then select Yes on next screen to confirm. Wait a while till the data wipe is complete.
  19. Select install zip from sdcard, then select choose zip from sdcard. Scroll to the ROM file on the SD card and select it. Confirm installation by selecting Yes – Install on the next screen. The ROM will start installing.
  20. After ROM installation completes, select choose zip from sdcard again, then select the file to install the Google apps package.
  21. After the installation is complete, select go back then select reboot system now to reboot the phone and boot up into CM10.

    how can I know if my one v is a GSM or CDMA ?

    • Blake

      GSM means you have a sim card (AT&T, Verison, etc)
      CDMA means you do not have a sim card (Sprint, Virgin Mobile)
