Android 7.0 Nougat – Root – PokemonGo
UPDATE 20161008 This blog is outdated, please see the updated version: Reload: Android 7.0 Nougat – Root – Pokemon Go
Since my switch to Android my Nexus 6p is rooted and I have happily fixed the Android (<7) font errors with Japanese fonts in English environment (see this post). The recently released Android 7 Nougat finally fixes this problem, so it was high time to update.
In addition, a recent update to Pokemon Go excluded rooted devices, so I was searching for a solution that allows me to: update to Nougat, keep root, and run PokemonGo (as well as some bank security apps etc).
After some playing around here are the steps I took:
WARNING WARNING WARNING The current version Magisk-v7 breaks everything – you will be lost without a SuperSU application, and will not be able to hide root. Do NOT use it. Unfortunately the version v6 was removed from the servers, but I keep the explanation here. Magisk might evolve in the future back to a usable solution, but for now I need more research. If you still have the files mentioned in this blog (Magisk-v6 etc), keep them, you want to use them! WARNING WARNING WARNING
Installation of necessary components
Warning: The following is for Nexus6p device, you need different image files and TWRP recovery for other devices.
Flash Nougat firmware images
Get it from the Google Android Nexus images web site, unpack the zip and the included zip one gets a lot of img files.
unzip angler-nrd90u-factory-7c9b6a2b.zip cd angler-nrd90u/ unzip image-angler-nrd90u.zip
As I don’t want my user partition to get flashed, I did not use the included flash script, but did it manually:
fastboot flash bootloader bootloader-angler-angler-03.58.img fastboot reboot-bootloader sleep 5 fastboot flash radio radio-angler-angler-03.72.img fastboot reboot-bootloader sleep 5 fastboot erase system fastboot flash system system.img fastboot erase boot fastboot flash boot boot.img fastboot erase cache fastboot flash cache cache.img fastboot erase vendor fastboot flash vendor vendor.img fastboot erase recovery fastboot flash recovery recovery.img fastboot reboot
After that boot into the normal system and let it do all the necessary upgrades. Once this is done, let us prepare for systemless root and possible hiding of it.
Get the necessary file
Transfer these two files to your device – I am using an external USB stick that can be plugged into the device, or copy it via your computer or via a cloud service.
Also we need to get a custom recovery image, I am using TWRP. I used the version 3.0.2-0 of TWRP I had already available, but that version didn’t manage to decrypt the file system and hangs. One needs to get at least version 3.0.2-2 from the TWRP web site.
Install latest TWRP recorvery
Reboot into boot-loader, then use fastboot to flash twrp:
fastboot erase recovery fastboot flash recovery twrp-3.0.2-2-angler.img fastboot reboot-bootloader
After that select Recovery with the up-down buttons and start twrp. You will be asked you pin if you have one set.
Select “Install” in TWRP, select the Magisk-v6.zip file, and see you device being prepared for systemless root.
Install SuperSU, Magisk version
Again, boot into TWRP and use the install tool to install SuperSU-v2.76-magisk.zip. After reboot you should have a SuperSU binary running.
Install the Magisk Manager
From your device browse to the .apk and install it.
How to run safety net programs
Those programs that check for safety functions (Pokemon Go, Android Pay, several bank apps) need root disabled. Open the Magisk Manager and switch the root switch to the left (off). After this starting the program should bring you past the special check.
