The Samsung Galaxy Alpha is part of the new Samsung range of smartphone and the SM-G850M is the LTE variant from the Vodafone phone carrier network. If you own that device and are running the official Android 4.4.4 KitKat software, you can follow the guide below for opening up the internal hardware away from the OEM restrictions.
- You must follow our guide below on the Alpha G850M variant only. You can verify that number matches with your device by navigating to the Settings > About Device and looking at the model number.
- Furthermore, you want that device to be running the official Android 4.4.4 KitKat update. You can check your software version from the same About Device menu as mentioned above. It’s possible Google patches this exploit in future OTA updates such as the Android Lollipop.
BEFORE WE BEGIN
- We recommend updating your Samsung USB Drivers  from our direct link. Once done, you’ll need to reboot your Windows PC to have the same drivers working.
- As I said before, you must use a Windows PC for this guide. The Odin app doesn’t work for Mac or any other operating system.
- Applying the steps does void any warranty you have left; thus jeopardizing the ability to send it away for free repairs.
