LG Optimus Black was released a long time ago. It is a good phone with a 1 GHz Cortex-A8 processor, PowerVR SGX530 GPU, 5 MP rear camera, 2 MP front camera and 512 MB RAM. It came with Android Froyo OS (2.2) which was up-gradable to Gingerbread and Ice Cream Sandwich. However LG did not go ahead with the Jelly Bean update for Optimus Black.

But the CyanogenMod team have made great efforts to bring Jelly Bean on the LG Optimus Black. CyanogenMod 10.1 nightly builds have arrived for the LG handset. CyanogenMod 10.1 is based on Android 4.2, and includes many of the cool new Android 4.2 goodies like notification bar power toggles, Swype-style keyboard input and a brand-new camera app.

Follow the steps given below to install Jelly Bean 4.2 on the LG Optimus Black.



  1. Download the zip files from the above links and place it on the root of the SD card.
  2. Reboot into the Recovery Mode.
  3. Make a Nandroid backup in case anything goes wrong.
  4. Perform a full wipe (wipe data/factory reset + wipe cache partition).
  5. Go to “advanced” and wipe the dalvik cache.
  6. Go to “Select zip from SD card” and choose the CM10.1 zip file.
  7. Now clear cache and dalvik cache.
  8. Go to “Select zip from SD card” and choose the Gapps zip file.
  9. After the process is complete, reboot the phone.

The device will take some time to boot for the first time. After it is successfully rebooted, the user will see that Android Jelly Bean 4.2 is installed.
