I am hoping I can bounce my plan of attack for updating my Pixel 2 XL that is already rooted (using Magisk Manager + Magisk) and currently running Magisk Manager 5.6.4 + Magisk v16.0 and Android 8.1 (build OPM1.171019.021) to the latest and greatest version of Android (looks like its currently v9.0 w/ build# PQ1A.181105.017.A1)
First off, I didn't use TWRP when originally rooting android v8.1 on my Pixel 2 XL previously, I didn't think I needed it and had no plan to ever install a custom ROM. I am still in this boat and would prefer not to install or use TWRP if possible. I went the route letting the magisk manager app on my phone update the (at that time) newest factory image of android then flashing that image back onto my phone via fastboot and everything went great.
Anyway - If anyone would look over my approach here and let me know if this should work or not I would appreciate it!
My plan for updating to android 9.0 and keeping root:
1. Download the last android factory image from google (currently PQ1A.181105.017.A1)
2. Backup everything on my phone I care about (pictures, etc)
3. Use fastboot to flash the latest factory image to my phone (I understand this will reset everything on my phone and I'll lose root for the time being)
4. Download magisk manager apk from ******************
5. Make sure my phone is setup to allow installation of apps from unknown sources, then install magisk manager on my phone
6. Use Magisk Manager to install magisk and use the option to "patch boot image file" to patch the boot.img file from the latest factory android image (currently PQ1A.181105.017.A1)
7. Use flashboot to flash the patched version of the latest factory android image (currently PQ1A.181105.017.A1) to my phone, then finally check that root is working by using Magisk Manager. Then restore my backed up files to my phone (e.g pictures)
Thanks in advance for the advice!
