Verizon may disappoint you by providing Android 4.2 update lately but Cyanogenmod won’t. Cyanogenmod is the only custom ROM that upgrades itself quickly after every Android version releases. When Google introduced Jelly Bean for the first time in June’12, it was Android 4.1. Subsequently Cyanogenmod 9 (which was based on ICS) changed to Cyanogenmod 10. And now after Android 4.2 release, it is CM 10.1.
Since CM 10.1 is already out for Verizon Galaxy S3, you need not have to wait for a long time to get Android 4.2 officially. Now you might be thinking that why I am praising Cyanogenmod so much? Well, the reason behind this is very clear. CM 10.1 not only offers you the latest Android version but also its own customization features. Those features include- fast & smooth interface, beautiful boot animation, CM settings that allows you to modify each & every parameter of your OS etc.
Are you ready to try out Android 4.2? If yes then we’ve prepared a short tutorial which will guide you to upgrade your Verizon Galaxy S3 i535 to Android 4.2 via goodness of CM 10.1.
Disclaimer: The procedure given in this tutorial is considered as risky and may cause damage to your phone. It is recommended that you should not follow it unless you are familiar with these things. Follow this guide completely at your own risk. Neither we nor Cyanogenmod team will be held responsible for any damage caused to your device while attempting these steps.
The guide is compatible only with Verizon variant of Samsung Galaxy S3 which bears model number SCH-i525. Dont try it on international variant of Galaxy S3 or on any other device else it may turn in hardware failure of your device.
- Charge your device up to 75% battery level so that you can install the ROM without any interruption.
- Enable / Tick ‘USB Debugging’ option in your phone.
- It is highly recommended to backup all your data from internal memory (includes contacts, messages (SMS/MMS), call logs, Internet APNs etc.). Your phone data will get lost after installation of this ROM (excluding External storage).
- It is necessary to have Custom Recovery like Clockworkmod / TWRP installed in your phone for flashing Cyanogenmod 10.1 Custom ROM. If you haven’t installed it yet, you can follow this guide for the same.
Procedure Required for Upgrading Verizon Galaxy S3 SCH-i535 to Android 4.2.1 (Cyanogenmod 10.1):

- Disconnect the phone from computer. Now boot into Clockworkmod recovery. For doing that, switch off the phone completely & wait till it vibrates. Now press & hold Volume Up + Volume down + Menu Button + Power Key together until recovery mode shows up.
- After getting into the recovery, make a nandroid backup of your current ROM so that the same can be restored back in case of installation failure. To do so, Highlight backup and restore option from the main menu of recovery menu, select it & then choose backup to start the backup process.
- Select wipe data/factory reset & subsequently wipe cache partition to wipe the data & caches respectively from the internal memory. (Caution! performing this step will erase all the data from internal memory, which includes SMS / MMS, contacts, reminders, APNs, call logs, apps etc. therefore ensure that youve taken backup of all these things before).
- Now select install zip from sdcard & then on next screen select, choose zip from sdcard. It will show you all the files & folders located on internal memory of your device. Navigate to the ROM file (which you’ve copied earlier from Computer), select it using power button (unless youre using touch CWM) & confirm the installation by pressing on Yes. This should start installing the ROM.
