OnePlus will soon release the Android 8.0 Oreo update for the OnePlus 5, but until then you can already try and test different custom ROMs based on the latest Android build. For example you can flash the new Ground Zero GZOSP firmware, a great Android ROM that can smoothly run on your phone. So, if you need further info on how to complete this particular update operation, don’t hesitate and follow all the guidelines from down below.
Ground Zero GZOSP is still under development stage but that doesn’t mean you shouldn’t flash it on your OnePlus 5. It can be successfully used as your daily driver, at least until OnePlus makes available the official Android 8.0 Oreo platform. The best is that through this custom ROM you can now test the latest features, apps and capabilities included in the stock Android system. Additionally you will also be able to use dedicated features that aren’t included in the default Oreo software. Through these particular features you can then choose to optimize, customize and personalize your smartphone and its performance.
Ground Zero GZOSP is a custom ROM so we are discussing about a free aftermarket distribution of stock Android OS. Therefore, you will be using an unofficial update developed by third party devs and which cannot be associated with your OEM. Shortly, because of these aspects you will lose your OnePlus 5 warranty – the warranty can be restored by reinstalling the stock Android software.
Now, for being able to safely test this custom release of Android 8.0 Oreo, you should first complete a Nandroid backup operation. In this way you can save the current Android OS that runs on your device. So, if the Ground Zero GZOSP ROM will not run properly, you will be able to go back to stock easily by flashing the Nandroid backup package.
A rooted OnePlus 5 must be used. Otherwise, the new ROM cannot be installed – built-in features and processes will be accessed, modified and customized during the update operation. Once root access is ensured you should also install TWRP recovery on your OnePlus 5 – the Ground Zero GZOSP ROM will be flashed through TWRP recovery so installing a custom recovery image shouldn’t be optional either.
A full wipe will be initiated during the Android 8.0 Oreo update operation. Shortly, everything that’s not there by default will be erased. Thus, you can lose your personal data, info, accounts and files – including contacts, call logs, texts, images, videos, audio files, market apps, internet settings and similar other packages. So, you need to make a backup for securing the files which might also be required afterwards. On the OnePlus 5 you can already use built-in cloud storage services, you can sync your data with your Google Account or you can get compatible backup and restore apps from Google Play.
Your smartphone, its USB cable and a computer are all required during the following steps. For being able to properly connect your OnePlus 5 with your computer, first you need to check the USB Debugging option on your phone – this feature is located within Developer Options. For enabling Developer Options you just have to tap on Built Number – tap on this field repeatedly, for 7 or 10 times, until you receive the ‘you are a developer’ message.
It’s important to charge your smartphone before starting the update process. The reason is simple: if the power is too low, usually lower than 50%, your smartphone can get turned off right while you try to install Android 8.0 Oreo. The bad thing is that soft-related problems can be caused within the Android internal system if that happens. So, try to avoid any unexpected problems and charge your device first.
Also, make sure you apply the following steps only if you own the OnePlus 5. The Ground Zero GZOSP custom ROM package offered below is compatible only with the already mentioned handset.
How to Install Android 8.0 Oreo on OnePlus 5 with Ground Zero GZOSP Firmware
- On your computer, if possible on desktop, download the Ground Zero GZOSP firmware package; the ROM can be downloaded from here.
- Download Google Apps from this page – you need to flash Google Apps separately.
- Power off your OnePlus 5 and then reboot to recovery mode.
- A wipe must be initiated at this point. Thus, from recovery you will have to select the following options: “wipe data factory reset”, “wipe cache partition” and “wipe dalvik cache”.
- Reboot your device in the end and connect it with your computer – just plug in the USB cable.
- Copy-paste the downloaded files from your computer to your smartphone.
- The computer is no longer useful, so you can remove the USB cable now.
- Go to recovery mode again.
- This time, tap on Install. Then, load the Android 8.0 Oreo update package and start the flashing process (just swipe).
- Repeat the last step and install Google Apps.
- And, in the end, from main menu of recovery choose ‘reboot’.
