Because of the Verizon Galaxy S3′s SCH-I535 locked bootloader, the device wasn't able to enjoy custom ROMs. Ever since its bootloader was unlocked, developers have had more ease in developing custom ROMs for it and have been rolling out a lot of Jelly Bean ROMs.

If you are an owner of this device and you are looking for a ROM to check out, try the MIUIAndroid ROM for the Galaxy S3 I535, courtesy of XDA Developers member Bleelas.

MIUIAndroid ROMs are known for their own unique apps like the home launcher, contacts, music, and a lot more. Another feature the ROM has that some users may be fans of is its inbuilt themes which also includes fan-made themes you can use on your device. MIUI's features, plus Jelly Bean's goodness, are definitely some of the things you should try now that your Verizon Galaxy S3′s bootloader is unlocked.

This guide shows you how to flash MIUAndroid ROM for the Galaxy S3 I535.
