Install /e/OS on a Samsung Galaxy S III Neo (Samsung Camera) - “s3ve3gjv”

The instructions in this guide will assist you to install /e/OS on your s3ve3gjv. Please read through the instructions at least once before actually following them, so as to avoid any problems later.

It is important that you know that downgrading Smartphones on OS versions greater than the /e/OS OS version you plan to install, can cause instability or at worst brick some devices. We recommend that you check your current OS version, before attempting the installation.

It is advisable to flash your device only if you know what you are doing and are ok taking the associated risk. All /e/OS builds are provided as best effort, without any guarantee. The /e/OS project and its project members deny any and all responsibility about the consequences of using /e/OS software and or /e/OS services.

Requirements

• If required take a backup of all important data from your phone on an external storage device before proceeding.
• Do not take a backup on the same device as some of these actions will format the device and delete the backup.
• Ensure your phone is charged more than 50%
• Check that adb is enabled on your PC. If not you can find the setup instructions here
• Download all the files and images mentioned in the download section below before starting the installation

• Make sure you have a working data cable to connect your device to the PC. There are cables which are only for charging and do not transfer data.

• Enable USB debugging on your device. You can find the instructions here
• Make sure that your model is listed in the Smartphone Selector. Check the model supported. Where available, information on the model supported should show as a pop-up when you hover the cursor on the Device name. The model number supported should be the exact same.

Important information

There are two possible hardware configurations of this phone regardless of model number. Some phones were released with a Sony IMX 175 rear camera sensor, while others with a Samsung s5k4h5yb rear camera sensor. As such, we’ve separated this device’s builds into two separate builds. The procedure to distinguish which to use is as follows:

• Make sure to be on the latest stock firmware of your variant (you can check updates with Settings, Updates);
• Make sure the rear camera is working on the stock ROM;
• Open the phone app and dial *#*#34971539#*#* to access to the hidden menu;
• An alternate code you can try out is *#34971539#
• Tap on ‘Phone/Cam FW Check’ and take note of the numbers shown in the notification:
  • For E08QT, install the s3ve3gjv builds
  • For B08QT, install the s3ve3gxx builds

If neither of these match, please make sure you installed the correct firmware version.

Preparing for installation using Heimdall

Samsung devices come with a unique boot mode called “Download mode”, which is very similar to “Fastboot mode” on some devices with unlocked bootloaders. Heimdall is a cross-platform, open-source tool for interfacing with Download mode on Samsung devices. The preferred method of installing a custom recovery is through this boot mode – rooting the stock firmware is neither necessary nor required.

Please note: On windows PC’s to run the installation using ODIN check this HOWTO. The steps given below explain how to install Heimdall and flash /e/OS
