Details of Note
- We recommend backing up the data. Most Android smartphones have a default utility for backing up and restoring. The process in finding that varies for each device. In addition to it varying, it relies on your manually going back and making more backups. That’s why we suggest installing one of the fantastic backup apps available from the Google Play Store. Helium helps you sync the phone contacts, make copies of the existing market apps and SMS texts. Check out Titanium backup from the same Google Play store after unlocking the internal hardware.
- Make sure you backup the EFS folder. The app here allows you to save EFS IMEI code. From there you can choose to restore EFS, backup partitions and more. You must do this after opening the device with root access.
- Furthermore, if you are considering installing a custom ROM after finding root access, we suggest taking a Nandroid backup. Nandroid’s backup nearly everything on your ROM and data. It can even remember where you were up to in games and save that data too!
- Feel free to back up the data and ROM any way you choose. There is no wrong answer, but there is several ways to back up. Follow your usual way if you don’t want to learn anything new.
- Install Samsung Kies for the latest USB drivers and syncing the phone contacts. You can download the drivers from third-party links or the official Samsung website if you don’t want to install Kies.
- Remember to disable Kies before opening the Odin application. They can interfere with each other.
- Moreover, temporarily disable the security features installed on the smartphone and the computer. You’ll find them as existing applications on the Galaxy S5. Note: the phone doesn’t automatically start with antivirus. If you didn’t install it yourself, it won’t be there.
- Make sure there is enough battery saved up on the phone so that it doesn’t turn off during the flashing. Remember most modern smartphones come with USB charging as a default feature. That means it charges the battery if it’s plugged into a desktop PC.
- You may use a desktop computer, notebook or laptop so long as it’s running Windows as the operating system Choose from Windows XP, Windows 7 and Windows 8.
- If the notebook or laptop isn’t plugged into the wall it doesn’t have direct power source and the USB charging feature may not be working. Make sure the notebook battery is charged enough to go with the phone.
