Android 4.1 Jelly Bean for LG Optimus GT540: CyanogenMod 10 (CM10) Installation Guide


Android 4.1 Jelly Bean and CM10. For the LG Optimus. That’s right, when we have such wonderful developers in the Android development community, old devices such as the Optimus never fade away into oblivion. XDA Senior Member DevSwift1 has released an alpha build of CM10 (CyanogenMod) for the LG Optimus, bringing the Jelly Bean mania to the old yet still alive Android device that debuted with the ancient Android 1.6 Donut and that many would not even think capable of running Android 4.1.

NOTE: The ROM is in a very early stage of development and is “highly unstable” according to the developer, so keep in mind that this should only be used as a preview of Jelly Bean/CM10 at this point as many things do not work properly yet. Also, CM10 is in a very preliminary stage right now, hence there are no specific customization features of CyanogenMod in CM10 yet.

Take a look at what works/does not work in the ROM:


  • GSM(almost)
  • GPS(not tested)
  • WiFi
  • UMS

Not Work:

  • Everything else

Let’s take a look at how you can install CM10 based on Jelly Bean on your LG Optimus GT540.


This ROM and the guide below are compatible only and only with the LG Optimus, model number GT540. It’s not compatible with any other device. Check your device model in Settings » About phone.


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.

    In recovery, use volume keys to scroll up and down between options and power key to select an option.
  6. Select wipe data/factory reset, then select Yes on next screen to confirm. Wait a while till the data wipe is complete.
  7. 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.
  8. After the ROM finishes installing, select go back then select reboot system now to reboot the phone to boot up into CM10.
