If you own a Nexus device you are one of the lucky users that have a chance to test Android versions right away. However, this might not be the case for older devices. Today, we will show you how to get the latest Android 8.1.0 Oreo features on your Nexus 7 (2013) device, thanks to the Ice Cold Project.
Update to the 8.1.0 Oreo custom ROM
Before we start, you have to install USB drivers for Nexus 7 (2013) on your computer. Then, make sure that USB debugging options are enabled. You can do that by going to Menu > Settings > Applications. Go to Developer Options and check if USB Debugging is enabled.
You should also make sure that your tablet is charged and it has at least 70%, that TWRP recovery is installed and that the Nexus device is rooted. Now we can begin updating the Nexus 7 to Android 8.1.0 Oreo AICP Nightly.
You will need to get the AICP Android 8.1.0 Oreo for Nexus 7 (2013) file. You should be able to find it online easily. After you download it, connect your tablet to the computer, via USB cable. Then copy the files you downloaded to the SD card of your Nexus 7 (2013).
Now disconnect your device, power it off. Then boot the Nexus 7 into Bootloader mode by pressing and holding the Power, Volume Up and Volume Down buttons at the same time. Go to recovery by following the instructions on screen, and there use the Volume keys to highlight and select with the Power button.
Go to wipe data/ factory reset for data wipe operations. You should wipe cache partition and then wipe dalvik cache as well.
Finally, press install and select the AICP ROM zip file. Install it and do the same for the root file. Finally, go to main recovery menu and select reboot system now.
