Once you have root access and a custom recovery image installed, such as TWRP Recovery or ClockworkMod recovery, you can start thinking about installing what custom ROMs are on offer for your device. The Ascend P2 isn’t the most popular smartphone in the world, and as such it doesn’t have the best developers catering to its needs. However, it is possible to update to a newer version of Android KitKat which your stock Android doesn’t have. here’s how to install Android 4.4.2 KitKat on the P2 thanks to a custom ROM known as Omni ROM.

REQUIREMENTS

• You can only use this guide if you have the Huawei Ascend P2 smartphone. Do not try installing it on any other.

BEFORE WE BEGIN

• Follow this guide at your own risk. It’s not a well-reknowned third-party developer.
• You should be an experienced Android user before following this guide just in case you want to get out of a soft-brick situation. Since you have already voided the warranty, you cannot get free assistance apart from online forums. Speaking of which, the best way to find help is heading to XDA Developers — you can find the original thread for this ROM here.
