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

Advertisement

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:

Works:

  • GSM(almost)
  • GPS(not tested)
  • WiFi
  • BLUETOOTH
  • SD CARD
  • UMS
  • HW ACCELERATION

Not Work:

  • Everything else

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