.I have been watching the S8/S22 telegram as well and I am a little confused now. Because normally you patch the AP you extracted from the firmware with magisk and flash that with odin and your rooted. However I see people talking about patching the boot img and the vbmeta and flashing that for root. I have never seen a guide that showed to just patch boot and vbmeta although I have never looked either. Im patiently waiting for this developer to finish twrp for a13. I prefer to root it that way for a few reasons. If you flash a magisk module or lsposed module and you bootloop because Android 13 just came out so bugs will happen. How do you fix that without recovery? You would have to flash stock and do everything over again. With twrp I make backup and if I cant uninstall module, I restore backup.
Yes you can root android 13 oneui I heard on the s8 ultra use magisk canary instead of stable.
how to root it exactly I don't know at the moment what method to use.
Loading 13 with odin was very straight-forward. Is done. I used HOME_CSC versus the CSC file to not factory reset and retain my settings... The discovery doc file says that I am Smarter and More Powerful now. Well, I seriously doubt that. I just re-ran Geekbench 5 and it says : 1173 and 3131, so those numbers are slightly less than with 12. I wonder how much new bloatware is running in the background stealing the limited, available clock cycles ?
Time to grab Magisk next.
Geekbench ML is 466. An 'no', you do not patch vbmeta but rather ( stock file next to boot image ) is re-written to toggle verity and verification to disabled . . .
Oh. Oh. I did read the act of re-writing the vbmeta file is a mandatory factory reset. Boo...
Disabling that vbmeta means you cannot buy girl scout cookies with your credit card using the tablet. No walking up to the Starbucks register and bonking your tablet on the swiper to pay for your morning cup of joe.
I re-read your post and saw where you say 'patch to AP' and that is not correct. You pull the itty bitty boot image file from the AP and patch that with Magisk. Hope everyone is safe and having a nice turkey day.
