Upgrade Firmware

Optimus l9 is one of the best midrange device ever released by Lg.This Ti omap processor smartphone was actually very good when it comes to performance while delivering a decent battery life.As Android was evolving rapidly lg failed to provide latest updates and was stuck at 4.1.1 jellybean.

If you are still stuck on android jellybean or just rooted your lg optimus L9 and took the advantage of root apps to optimze user interface but not satisfied at all its time for you to shift to a custom rom on your P765.

This was a highly successful lg device and has been released with many model numbers depending on regions.There are 4 models available namely P760, P765, P768, P769.If you have a P765 then you can flash this cyanogenmod 12.1 on your device and this roms is not meant for other models of optimus L9.

Flashing this on other variants of L9 might result in lot of app crashes and unstable os or even cause brick which you may not like at all.So if you don't have P765 then be away from this.Since updating your smartphone using custom firmware is a risky one we take no responsibility if you brick the device.

This rom is also flashable on P768 but you will be camera might not work.If you don't use camera much then you can flash it but still we are not at all responsible if any thing happens to your device.
