The Verizon Galaxy S3 has just received a brand new OTA update and the guys at XDA, mainly scrosler who is a recognized developer, managed to root and deodex the firmware and now, he released it for users to experience the latest Android 4.0.4 without problems. Read this article and you will learn how to properly flash this using CWM Recovery on your I535 smartphone by Verizon.
This firmware update is of the version VRALG7 and it was an OTA release that has been deodexed and rooted so that you will be able to install it manually. Since the ROM is already rooted, you won’t have to worry about searching any other Root guide to gain access to your device’s system sub-folders.
VRALG7 ICS update fixes the NO SIM bug and adds some new functions and features that will improve the overall performances of your device. Since this firmware is already deodexed, it means that it comes with ROM theming support. This guide teaches you how to manually update your device with it. In order to correctly install this update you should read the preparation guide below and learn what steps are needed in order to configure the Galaxy S3 Verizon.
This firmware is official and the only difference is that it is rooted and you won;t be forced to look for any other guides after the install. Now that you know all of this, I think that you should move to the preparation guide, below.
- The VRALG7 ICS 4.0.4 Update will work exclusively with the Galaxy S3 Verizon variant with model number I535. Check your phone’s version by opening Settings and then verify the info listed under ‘About device’. If your device is I535, then you can move to the next step.
- Your smartphone should be on an unlocked Bootloader. Also, it should be running a CWM Recovery image and it should be already rooted.
- Move all your important files on your device’s internal sdcard. That one won’t be deleted in the updating process.
- Applications, Call Logs, SMS and APN Internet Settings can be easily backed up using these apps: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android. Note that your phone should be rooted for these apps to work with it.
- You can save all your Phone Contacts by syncing them with the Gmail account you’ve assigned for your device.
- It is recommended for you to create a full backup of the existing ROM. You can find more about this in the tutorial or, you can choose to use ROM manager to create a full Nandroid backup.
- USB Debugging option should be enabled on your device.
- Remember to charge the Galaxy S3 I535 battery and this will prevent it from powering off during the firmware update.
- Any bugs you find should be posted in comments, at the end of this post. Also, note that we cannot be held responsible in case your smartphone gets bricked or you lose any important data while upgrading its ROM.
- In case you have trouble completing this update, you should ask for more in our comments field.
- You can find more Galaxy S3 Verizon I535 tutorials by clicking on the device’s name link ( it is the one listed under this article’s featured picture).
I think that these are all the general guidelines that you had to read and now you should move to the next part of this post and learn how to manually flash this firmware update on your device. Make sure that you don’t skip any steps that I have listed in the tutorial, as that will result in a failed attempt and you will then be forced to repeat the entire tutorial twice and that is something that I’m sure that you won’t want to happen.
You should be able to flash this new ROM in under 10 minutes, including the backup time also. Remember that you will find a step that teaches you how to backup the ROM, but in case you already made such backup, then you should skip it. Now that you know all this, move to the tutorial.
How to update Verizon Galaxy S3 with VRALG7 ICS 4.0.4 Firmware
- Download the ROM file from HERE. Save the file on your computer’s desktop and do not extract its contents.
- Next thing that you should do, is to connect your PC with your smartphone and move the ROM on the internal SD card. Disconnect the systems after the transfer is complete.
- Power off your smartphone and boot into CWM Recovery mode. Do it by pressing ‘volume up’ + ‘home’ + ‘power’ buttons until the screen powers ON. When that happens you can release the buttons and continue to the next step. Make sure that your device isn’t connected to your computer.
- Now you can create a full NANDROID backup of the existing ROM. Select the ‘backup and restore’ option from CWM Recovery menu first screen. After the backup is finished you should return to the same first recovery menu.
- Next, select ‘wipe data/ factory reset’ option and after that confirm that you want to wipe all this data. Note that the internal SD card data file won’t be deleted and you shouldn’t worry about them. When this wipe process is finished, move to the next step.
- Select ‘install zip from sdcard’ and then select ‘choose zip from sd card’. Find the VRALG7 ICS firmware ROM and confirm its installation. Return to the main recovery screen after the update is complete.
- Select ‘reboot system now’ and wait for your phone to boot into this new ROM. In case the first boot process takes too long to complete ( i.e over 10 minutes) or it gets stuck into a boot loop, then you should power the device off completely and then boot again into CWM Recovery mode and repeat the entire tutorial again.
- In case all went as it should’ve, then you should see the main Android welcome screen and you simply need to add your Google Account details and you will regain control completely over your smartphone.
- That’s it, you’ve managed to manually update your Verizon Galaxy S3 to the latest ICS VRALG7 Android 4.0.4 firmware.
I hope that the update was complete. In case you cannot finish the tutorial, you should post a detailed comment at the end of this post and tell us exactly what steps you took and where you got stuck, and we will try to help you.
Remember that this firmware update is already rooted and deodexed, this means that you won’t have to re-apply any root after its installation.
