How to update Lava Iris 501 to Official Android 4.1 Jellybean firmware

Lava Iris 501 Jelly Bean

Lava Iris 501 is an amazing device which offers you good multimedia and gaming performance at a budget price. The device is available with ICS and now through an update rom you can have Jellybean on it. Compare to other budget phones in the market, Iris 501 still counted as the best one. This is due to bigger screen size and great output. I had tested this device for long time and played certain HD games also. It works well and there is no performance problem in that.

In this short tip I will show you the way to install an updated Jellybean rom on the device. The version is Android 4.12. This new rom will add more features and boost the device output to some extent. So if you are really fed up with the existing interface then you can follow my guide to get Jellybean Os on the device. It is tested and works fine. But before going ahead just checkout the requirements. This is important things to consider, because if this is not properly done, your phone might brick.

Lava Iris 501 has officially got this update. The below method is manual. If you are not really sure how to do this then you can also go to LAVA service center to get the new update. This is an official update not a custom rom. So there is nothing added in that. You are getting a stock Jellybean ROM here.
