Android Jinn reported that MIUIAndroid is the custom ROM to install Android 4.1.2 Jelly Bean into the Motorola Photon 4G. It brings Jelly Bean features such as the smooth interface, improved notifications, advanced voice recognition service, smarter keyboard, offline voice typing, Google Now and more to the Motorola smartphone. It should be noted here that Motorola Photon 4G, with a dual-core 1 GHz Cortex-A9 processor and 1GB of RAM, is competent enough to run Android 4.1.2 Jelly Bean smoothly.
In addition, since the MIUIAndroid ROM is built using MIUI Version: 2.12.7 and AOKP Milestone 1 FINAL, the users will get a lot of customization options.
Below is the tutorial to install Android 4.1.2 Jelly Bean on Motorola Photon 4G using custom ROM MIUIAndroid developed by XDA Developers member Th3Bill. But there are some prerequisites that users need to know:
