Hello. I prefer using magisk over SU. And I just wrote up a guide a few days back on how to do that (as long as your running Android Oreo/EMUI 8.

That's tough to answer.....it's all a manner of opinion really. I had slightly better SOT though in emui 5 (since its running Android Nougat) where as emui 8 us Android Oreo. Truthfully I flashed an AOSP ROM after I upgraded to emui 8 because once you go to emui 8 / Android Oreo, it enables treble support. I'm not a big fan of emui in the first place though. However, the AOSP ROM's are newer so they are still wip when it comes to working 100% for the huawei mate 9.
May I ask what custom ROM you are using? And how do you find it? What's your SOT?

Download firmware from http://pro-teammt.ru/firmware-database/ (if available) and unpack update.app from update.zip
Open update.app in Huawei Update Extractor and extract ramdisk.img, this is the boot image file that magisk manager needs to patch.

I'm currently using fRomFuture, and truthfully i was gonna get oreo the install RR (assuming it can work with my model). My screen on time is around 4-5 hours. If you're willing id appreciate some help on the process cause installing roms and stuff on huawei is not my strong point

Okay... Sorry for the delay.
You'll obviously have to go back to stock first. And then hisuite should work to upgrade to Oreo. Just trying to think what the best way to return to stock would be for your model version and get you upgraded to Oreo.
i see this requires Microsoft Windows. i only have Linux. any suggestions?

Too late... unless you've got a bootloader unlock code before July 24. Did you? I'll guess not, hence...no root for you, enjoy GPU Turbo and Pie (whenever that comes).

Just got Pixel 3... got some rooting questions...

Just got Google version P3 and it's on November Android 10. Unlocked bootloader, but seemingly no can do on TWRP? If yes, how? If no, can I downgrade to 9.0? Pros and cons?
Thanks in advance!

You can root on Android 10, just not with twrp as it doesn't work on 10. You'll need to patch a boot.img with magisk on your device and then flash that with fastboot from your pc. There are guides for this.
Thanks for that! I just downgraded to 9.0 and rooted while I was waiting, but any real good reasons to use 10?

Question Android 12 to 11

How to downgrade Samsung 21+ devices from One UI 4.0 (Android 12) to One UI 3.1 (Android 11) via Odin.
I'm looking for the same answer. It's been a long time.. Like 8-10 years since I've rooted or modified a Samsung phone through Odin..
Idk if I can just download the android 11 firmware, unlock bootloader, and flash in Odin or if I first need root access..
Android 12 blows
Yes please. Android 12 is atrocious.
Edit: It's downgradeable ez pz. Just download the latest Android 11 and flash via Odin. I have the Exynos version.

I'd wait for a few more iterations before upgrading, so they smoothen things out a bit. The interface will stay ugly tho. "Material you" or whatever it's called is the most atrocious thing ever, especially the dark theme. I'll never upgrade to 12, I already disabled the automatic updates.
I have Android 12 and I didn't find much difference from Android 11 in my normal use, just some little bugs on 12 but that's it.

Question LE2117 Android 13 Update

My model is Oneplus 9 T-mobile Variant and I have waited so long for OOS 13 but it doesn't have any notification about it then I am still stuck at 12. So how to experience OOS 13 without waiting for T-Mobile to release it?
Well, T-mobile makes me really disappointed...
Use Tmobile MSM tool to downgrade, then convert variant to Global, then update to A13.
