Android Open Kang Project team has finished the work on Build 5 Jelly Bean release and now you can finally flash their custom ROM on your Android device. It is the first release of AOKP that is based on the Android 4.1.2 firmware which comes with several tweaks and improvements.
The new release of this custom ROM can now be installed on the AT&T Galaxy S3 and the AT&T Galaxy Note, while the AT&T HTC One X / One XL support was removed. The AOKP Jelly Bean 4.1.2 Build 5 is available for 27 Android phones and tablets. It brings a custom NavBar that for tablet devices, the NavBar widgets have been re-added from Ice Cream Sandwich builds, a Lockscreen Ring with support for customization and it also features a new editor that can be access from ROMControl. The base part of the editor in ROMControl has been delivered by the CyanogenMod team which might mean that AOKP and CM will finally begin to work together and that can mean only good news for custom ROM enthusiasts.
Other features present in Build 5 of JB are the RAM Bar shown in Recent menu, menu UI Overflow Toggle, a button was added to disable the vibration from the Notification expansion, timeout and instant lock options for the Slide Lock function. We can’t confirm any other new features as you should apply the update and see for yourself what new things have been added to AOKP build 5 JB. Users that are coming from build 4 of AOKP Jelly Bean 4.1.1 might not necessarily need to flash this latest custom ROM as that one was very stable. However, if you decide to upgrade your Android phone to AOKP JB build 5 from build 4, then you won’t have to wipe data/ factory reset it.
Check the list of supported devices by going to AOKP’s Jelly Bean 4.1.2 build 5 device dedicated web page.
