Galaxy S5 Android 8.1 Oreo Review/Install Guide!

For those of you who want to revamp your old Galaxy S5 or want to buy a cheap Galaxy S5 on ebay and put the latest Android 8.1 Oreo, here’s a quick review/install guide.  No root required!

Installation is really easy, you do NOT need to root your phone.  Simply install TWRP recovery then install ROM/Gapps and reboot.  Will work on any Galaxy S5 supported below.  This is the Resurrection Remix ROM which comes with all the standard features of latest Android 8.1 Oreo along with slew of customization.  For example, you will be able to customize your status bar(center clock) or even customize your hardware buttons(e.g. back button become camera button).

Performance also much improved with Antutu scores nearing 70K so you will have lag-free performance.  Now, this is NOT a TouchWiz-based ROM, meaning you will get nearly pure Google OS just like on Nexus devices but even better since you get the added customization from Resurrection Remix team.   Also, camera works flawless and 4K video recording is supported.  In my testing, I found everything working out of the box including WiFi, calls, 4G LTE, etc…etc…  If you are still on laggy Samsung TouchWiz or older Android OS, this is definitely the best way to make your phone new and start over.

This will work on the following models:

  • SM-G900F, SM-G900M, SM-G900I
  • Canadian SM-G900W8
  • T-Mobile SM-G900T
  • Sprint SM-G900P
  • Verizon SM-G900V (MUST UNLOCKED BOOTLOADER FIRST SEE HERE)

Q&A

Q: Does this work on AT&T SM-G900A?
A: Unfortunately no, the AT&T SM-G900A has a locked bootloader and no one has been able to figure out how to unlock the bootloader yet.  Your best bet is to sell your AT&T SM-G900A and grab the T-Mobile SM-G900T instead which will allow you to fully root and also use fully on AT&T 4G LTE network.

Q: Does this work on Verizon SM-G900V?
A: Yes, but you need to unlock the bootloader first.  Please see this post. Once bootloader has been unlocked, you can flash any S5 ROMs like a regular klte.

Q: Will this allow me to enjoy latest Android 8.1 Oreo?
A: Yes, you will be able to enjoy the latest Android Oreo along with slew of customization/features Resurrection Remix ROM brings.  Performance will be enhanced and also your battery life will improve with latest Android Oreo custom ROM.

Q: Does this ROM work on Korean SM-G900K, SM-G900S, or SM-G900L?
A: Korean models are not supported but there are ways you can make it work, see: https://forum.xda-developers.com/galaxy-s5/general/guide-boot-sm-g900f-roms-korean-galaxy-t3482001

Q: Why do I need to flash Gapps?
A: You need to flash Android 8.0/8.1 Gapps since most custom ROMs do NOT come with Play Store.  It is easy to do, simply flash Gapps after flashing ROM with TWRP recovery, that’s it!

Q: Do I lose all my apps?
A: If you are coming from stock firmware, yes.  You will have to start over since custom ROMs like this are not usually compatible with stock firmware.  However, you will be able to update to newer versions of this custom ROM without losing apps by simply flashing over ROM and Gapps without factory reset.

Q: Do I need to root my Galaxy S5 to install this ROM?
A: No, you only need to flash TWRP recovery to install this ROM.  TWRP recovery allow you to flash any custom ROM and it is easy to install TWRP using ODIN as shown in the video above.

Q: I am a beginner, can I do this without problems?
A: Yes, anyone can indeed install this if you follow the video tutorial step-by-step.  Please only install ROMs on a phone you don’t use or at least have a backup phone so if something goes wrong, you will have another phone to make/receive calls.  Use your common sense and don’t install ROMs on a phone you absolutely need at the moment.  Also give yourself plenty of time(few hours) to install a ROM so you don’t hurry and miss a step.

    The 4/5 release of RR Oreo v8.1 (RR-O-v6.0.0-20180405-klte-Official) is good but has several flaws that make it not ready for day-to-day use.

    1. Boot time (on SM-G900T) is 50 seconds compared to 20 seconds on Samsung’s Marshmallow v6.0.1 or 33 seconds on LineageOS-UnOfficial Oreo v8.1

    2. Video is sluggish (compared to Samsung or LineageOS) – Play BallZ and you will see the difference

    3. Battery drains dramatically fast compared to Samsung or LineageOS. A full battery lasts 12 hours on Samsung, 8 hours on LineageOS and 3 hours on RR.

    4. No support for T-Mobile’s WiFi-Calling. Lineage OS also has no support for WiFi-Calling.

    I flashed Resurrection Remix Oreo released /klte/RR-O-v6.0.0-20180425-klte-Official.zip to my galaxy s5.
    I cannot get sidesync to work and there is no app file you can place on the home screen to contain other apps instead of just listing them on a page. Finally, what is the best way to update oreo, where do I go for future updates. Your help is appreciated.

  19. Michael Mildner says:

    Correction, sidesync does work. You must change some app settings on sidesync to work. On marshamallo galaxy s5 you can install with no app setting change.

    In marshamallo you could create an app folder from the three dots where all the apps are listed. Then you can put all your communication apps in one folder, all your astro apps in another folder, all your photo apps , also in another folder, etc. Whereas in Oreo you have just one folder or page that list all your apps in alphabetical order. You need to remember the apps name to scroll the Oreo app page alphabetically. I have not found an application that can make an app folder described above.

    The people working on Oreo updates might review all the tried and true features of KitKat to marshamallo and incorporate them into future updates. Not an easy task to do a proper analysis

    I like Oreo a lot, especially the missing memory hogging battery draining applications from other vendors and tmobile, lookout and Samsung apps that everyone hated, but could not delete because it might cause other system apps not to function properly.

    What a joy to be able to put Oreo on galaxy S5 that was headed for the bone yard and give economically deprived individuals a chance to pick up a great Samsung smartphone with a current operating system for under a hundred dollars.on ebay, instead of paying much higher prices. This is a major breakthrough. A font forget the Galaxy S5 has a micro SD slot allowing you to insert a 128 mb (or more) that can be partitioned to increase your internal memory far beyond 32 gb , and give many GB of external memory use such apps as app2sd program.

    Some one concepts mentioned above are going to revolutionize the smartphone industry.

    My sincire appreciation to all the Oreo team members that worked hard on this project. Also, a special thanks to Max.

  20. Michael Mildner says:

    Correction on a orrection. You can create an app folder that can contain other apps on Oreo by simply placing one app directly over another app. I missed this feature because I did not see a direction to create a circular app folder. In marshamallo you have a direction to create an app folder when you press the three dots you will see create folder. Oreo allows you to name that new group of apps below the circular app folder.

    Also, I thought I solved the problem to get sidesync working on Oreo, but now back to the drawing board. On marshamallo I used sidesync on my phone to connect by USB to my Lenovo T520. I like using a USB connection for a more stable video than using WiFi with its static interference and sometimes shaky picture. I like sidesync, but looking for another alternative using USB.
