Root Galaxy S5 G900F Running Android 5.0 Lollipop

Samsung has this habit of surprising the users with updates at an expected time. While the users were not hoping for the Android 5.0 Lollipop to hit Samsung Galaxy S5, Note 3, Note 4 or any other device anytime around December, 2014, Samsung just surprised em’ and just today, started rolling out Android 5.0 Lollipop update for the Galaxy S5’s LTE variant SM-G900F based on the build number LRX21T. It’s just been a month since Google provided the Lollipop source code to AOSP and we think that Samsung has done a very nice job by bringing up the Android 5.0 Lollipop firmware for its current flagship device. Since this is a major Android update, there’s a number of prominent changes that makes this firmware worth having on the device.

The change atop of the Android 5.0 Lollipop update is in the display department. Google introduced a new UI, named as Material Design. Material Design makes the interaction with the elements on the display pretty much natural, it looks quite flat and cool, which also makes it much smoother. Google has added animations to all the elements in the UI, which makes it look eye-catching. Because of this major change in the UI, Samsung had to re-build all the applications to meet the requirements of Material Design. Samsung has added color status bars to its own applications, new fonts. On the new feature end, there’s priority mode, heads-up notifications, Mirror Link, Smart Lock and much more. You may install Android 5.0 LRX21T on your Galaxy S5 SM-G900F using our guide here.

In case you’re an Android power user and you’ve lost root access after flashing Android 5.0 Lollipop on your Galaxy S5 G900F, you would like to obtain the root access ASAP again. That’s what we are here for currently. In the proceeding guide we are going to root the Galaxy S5 G900F powered up with the Lollipop Android 5.0. Let’s go through the early preparations and then begin with the rooting process.

Early Preps:

1. This guide is only for Samsung Galaxy S5 SM-G900F

Make sure that your device is exactly as mentioned above. To check out what device you have, go to Settings > More/General > About Device or Settings > About Device and match the model number. Be careful about the device model number, flashing a file on a device not listed here might result in bricking it up.

2. Battery should be charged at least 60%!

Your device’s battery shouldn’t be weak. In case your device goes dead during the flashing process, your device may get soft bricked and you might be in need of flashing stock firmware and that will ultimately result in wiping up your data as well. So, make sure that you charge your device before you start the flashing process.

3. Use the OEM datacable to establish connection!

Always use the original data cable to establish connection between your Android device and your computer / laptop. Using ordinary data cables might interrupt the flashing process, so to avoid any mishap, you need to meet this requirement as well.

4. Backup everything!

Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. You may backup everything as listed below.

Backup SMS Messages
Backup Call Logs
Backup Contacts
Backup Media – Copy your files manually to your PC or Laptop.

5. Turn off Samsung Kies and other softwares while using Odin3!

Make sure that you turn off Samsung Kies while using Odin3 flashtool. Samsung Kies will interrupt Odin3 and will result in causing errors and may not let you flash your desired recovery or root file. Also, make sure that you turn off any antivirus software you’ve installed and also disable firewall to avoid any connection and flashing issues.

6. Disclaimer
