Install Android 4.2.2 AOKP Jelly Bean MR1 build 4 custom ROM for the Verizon Samsung Galaxy S3
Verizon Samsung Galaxy S3 can now be updated to Android 4.2.2. You can do it only if you’re rooted and you prefer to use a custom ROM before the official update. Read all the info in this post and you should be able to flash the AOKP JB MR1 custom ROM without problems.
This Android 4.2.2 based custom ROM is created by the Android Open Kang Project team and it has reached a stage when it is pretty stable. If you’re a ‘ROM tinkerer’, I don’t even know if there is such a thing, then you should give it a try. Remember that this is not a final build of the AOKP JB MR1 custom ROM, as there is still a lot of work to be done. In order to make sure that you can complete the installation of this new custom ROM, read the guidelines below:
- This tutorial will work only for the Verizon variant of the Samsung Galaxy S3. Do not attempt to install it on any other device as you might risk bricking it.
- Your device should be rooted and running a custom Recovery such as CWM Recovery. Without these you cannot install any custom ROMs on your smartphone.
- Use the ClockworkMod (CWM) Recovery to create a full NANDROID backup of your current ROM. This will set a restore point for your device.
- The tutorial contains a step that asks you to wipe data and factory reset your smartphone, which is why you should move all important data to your device’s internal SDcard or, you can choose to move it on to your computer. NOTE: If your phone is already on a previous build of the AOKP JB MR1 then you can leave all data files where these are located.
- If you want to backup SMS, Call logs info and APN Internet Settings use the following tools for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android application. Note that some of these tools will ask for root access and you have to grant it.
- If you don’t want to lose any Contacts data, then you should sync them with your Gmail account.
- This is a guide for advanced Android users and you shouldn’t use it if you’re a novice and you don’t know what you’re doing.
- We cannot be blamed in case you brick the device or you lose any data in the process. Make sure to read all the instructions and that you won’t skip any steps listed below.
- Enable USB Debugging option for your device.
- Make sure that the SGS3 Verizon has enough power left in its battery, as otherwise the phone will power off during the update process.
I think that these are all the instructions that you had to go over before continuing to the tutorial guide.

In case the first boot process of the AOKP JB MR1 build 4 takes over 5 minutes to complete, then you have to power off the device completely. Boot again into CWM Recovery mode and repeat the entire tutorial once again. Make sure that you apply the actions listed under the step 7 as that might be why your device is not booting the new ROM.
If you have any other questions then you should post them in our comments field.
Also, if you don’t like this new ROM then you can boot the CWM Recovery and then restore the backup of your previous ROM.
