Finally :Stock Android 9 Pie, Oxygen OS 9.0.2 for OP 3/3T

Those are pretty basic questions actually. I assume you haven't rooted your phone in recent time?
I just flashed the magisk zip before first boot into system to keep twrp and one restart settled things and magisk is now working fine.
I am using mcd kernel build r27 but it has broken Hotspot functionality, which I don't care much about.
Why would the bootloader get locked after flashing OOS? You need to manually go into fastboot mode and manually enter some commands to lock/unlock bootloader. It can't be done via recovery afaik.

So when in twrp, flash oos then format phone and then flash Magisk and reboot?

Make sure you take a complete back up of your internal memory. The Pie firmware has a bug where it will corrupt your internal data if you are flashing it on top of oreo firmware on an encrypted storage and unlocked bootloader. Here is what I did when I flashed the Pie OOS:
1. Bakcup internal memory to laptop.
2. Went to twrp and factory reset.
3. Then I "formatted" my internal memory. Note that I didn't just wipe, I formatted internal memory to remove encryption.
4. Flashed full OOS Pie zip. Then flashed twrp image in twrp. Then reboot to recovery. (this is important as rebooting into system without flashing magisk will flash stock recovery automatically).
5. Flashed magisk 19.2.
6. Reboot to system. It should now take about 15 minutes as OOS will re-encrypt your internal memory.
7. Reboot to recovery, flash my titanium backup zip, flash mcd kernel, profit!

You should really flash and see. That way, you can check all the features, check the stability, and see if it's really THE rom for you. If it isn't, you can always flash back to oreo OOS builds. Cheers! :good:

Thanks for this detailed instructions. I have a few questions. Where did you get the full OOS zip?

When you did the factory reset was it just that? No clearing data?
Then you just formatted, and then flashed the zip, and twrp IMG?

Lastly what is that MCD kernal?
Thanks again

Maybe I'm being stupid but if you format your phone how do you flash anything afterwards? Won't it all get deleted when you format?

You are supposed to have everything including your backup on your PC/Laptop and after formatting, transfer TWRP, ROM, Magisk etc to your phone while in recovery and flash from there.

Yup, just like he said, its a common practice to have everything ready on a OTG or your laptop which can be easily copied while in recovery mode. I even take weekly backup of maybe the 2 photos I'll take using the phone camera to make sure I've always a backup ready in case of anything happens.

Thanks guys, I wasn't aware I could copy anything to the phone while in twrp, I've always just flashed from internal storage.

We all learn something new everyday my friend. Just feel free to quote or dm shall you need any help.
BTW, sometimes, or maybe often at times, you need to mount OTG while data is always moutned. But I wanted you to keep in mind that in case internal memory copy doesn't work, just make sure your OTG or data is mounted in recovery.

i was in stock Android 8.1, and I was getting 2/2.45 hours of SOT. Because my "android system was sucking up all my battery. I tried couple of things. Like, clearing the cache of Google play service. Clearing cache via TWRP but nothing helped. I was constantly seeing my battery empty when I wake up in the morning. But when I upgraded to Android 9, the is no "Android system" in my battery usage chart. I am still testing my SOT but its not draining like crazy before.
