A new leaked update from Samsung (maybe?) for the Verizon variant of Galaxy S3 I535 has been released by an XDA Forum member, jucytec. If you want to install it on your device, then you should read the entire post. Note that this is not an official update but a leaked build and a custom ROM compiled as JellyWiz. This is a full stock ROM build and it still features several themes and the Android 4.2 leaked keyboard variant.
In order to correctly to update your smartphone with this ROM, you will have to read the preparation guide first. You will learn which steps you need to take in order to correctly flash all the files. Note that you have to wipe all data from your device in the process and in the prep guide you will find several other apps that can help you with that. Here’s what you need to know:
- Install this update only on the Verizon variant of the Galaxy S3 with the model number SCH I535. Check the version of your phone by opening Settings and checking the info listed under ‘About device’. If your phone is different from this model then you shouldn’t attempt to flash the files listed in this post.
- Unlock your device’s bootloader before installing this new custom ROM. Also, your device has to be rooted and running the CWM Recovery image. Without these you cannot flash any custom ROMs on your Verizon SGS3.
- Use CWM Recovery or ROM Manager and create a backup of the currently installed ROM. This file will be very useful in case something goes wrong as you will be able to restore the backup file.
- If you want, you can create a list of installed apps and backup SMS, Call Logs and the APN Internet Settings using these Android utilities: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android. Some of these apps will ask you for root access and you should grant it.
- Sync your Contacts app with your Gmail account and this will prevent it from powering OFF.
- Enable USB debugging option from Android Development menu. Charge the phone’s battery so that it won’t power off during the installation of JellyWiz Android 4.1 ROM.
- Note that this is a guide for advanced users and you shouldn’t attempt to apply the changes in case you’re a novice user.
- Do not blame us in case something goes wrong and you cannot use the phone after installing this new ROM.
These were all the guidelines you had to read before moving to the next part of this guide.
How to install leaked Android 4.1 JellyWiz ROM on Verizon Galaxy S3:
- Download the custom ROM zip from HERE. Don’t extract the zip contents.
- Download the Modem file from HERE. This file will change the smartphone file to a new version. Don’t unzip.
- Connect your smartphone to your PC. Move both files listed above on the smartphone’s internal SDcard.
- Power off your device after you disconnect it from computer. Now boot it into CWM recovery. It can be done by pressing ‘volume up’ + ‘home’ + ‘power’ buttons at the same time. Release the buttons when the CWM Recovery boots successfully.
- When the ClockworkMod Recovery main menu appears, select ‘wipe data/ factory reset’ action and then confirm it. Wait until the data is deleted and then move to the next step.
- Next, select ‘install zip from sdcard’ and after that select ‘choose zip from sdcard’. Find the custom ROM zip and confirm that you want to install it.
- When the ROM is installed, you have to select once again the ‘choose zip from sdcard’ option. This time you have to install the VRLI5 modem zip file. Confirm.
- When all the files have been installed you should return to the main recovery screen. Select reboot system now and wait for the first boot process with this new ROM to load all necessary files. This shouldn’t take more than 5 minutes to complete.
- Test the ROM and then tell us in comments if you find any bugs or errors while using it.
Take control over your phone after the phone boots and then start testing this new JellyWiz VRBLI5 leaked firmware.
NOTE: if the first boot process takes too long to complete or it gets into a boot loop, then you should power off the device and remove its battery. Re-insert it and then boot again into CWM Recovery. This time make sure that you don’t skip any steps listed in the tutorial.
