How to upgrade rooted Android 9 to rooted Android 10 (830) - Samsung Galaxy Tab S4 Questions & Answers

Posted in the other forum so I'll move it here
I'm on rooted Android 9. Used the method in another thread, installed TWTP, dm-verity, WETA kernel etc. Never had any issues.
What's the step by step to upgrade to Android 10?I have the downloaded firmware and the latest Odin. Also d/l the newest TWRP. Should I update TWRP first? ( In TWRP)
Then how to flash 10 and stay rooted? Doni need to go through the whole process again to root?
Any help welcome - thanks in advance!

rooted what? stock? custom ROM? GSI?

Stock rooted. Using TWRP, Weta kernel , decrypted and Magisk.

[Q] Need help! Steps on installing lollipop with custom recovery + root

Hi guys,
I'm not sure exactly where to look for the steps because I'm in a unique situation or atleast I think I am. I need help on installing the LOLLIPOP firmware (N900TUVUFOB6) with a custom recovery and root. I am currently on a rooted note 3 v4.3 with the N900TUVUBMI7 baseband version.do I need to update my bootloader to a newer version? Should I atleast do a stock update to 4.4? Should I be using which custom recovery?
If I'm correct, I can't just flash the latest custom recovery and then flash the newest lollipop (for example the newest TEKHD like this link http://forum.xda-developers.com/showthread.php?t=2672393
Or can I? What If I just did a normal software update to upgrade me to lollipop, will the bootloader be blocked, disabling me from installing a custom recovery since I would want to root as well. And then would I be able to resume the steps from TEKHD instruction?
Thanks!

Safe to install stock ROM with TWRP

I recently rooted and installed TWRP on my oneplus3.
There is a stock update available for my phone: OxygenOs 4.1.0.
TWRP seems to block the automated install and based on what I read on their website I shouldn't install it that way.
Can I download the stock ROM from h2os and safely install it with TWRP? I wanted to ensure this wouldn't cause issues

Flashing Update help pls

I am on an old version of 8.1 on my Pixel XL, I am unlocked, rooted w/magisk , and have newest version of TWRP.
I was browsing the roms section and most require being on the newest stock image.
So my question is, can i just flash the stock updated image using TWRP or do I have to install the image, re-root, and reinstall root?
Way back in the day i remember just using TWRP and flashing whatever rom i felt like using for the day without much extra work but have been out of the ROM gave for some time but would really like to take advantqage now of a good rom.

Downgrade from Android 10 to 9

Hey guys!
I'm rooted with magisk on this ROM - https://forum.xda-developers.com/oneplus-5t/development/rom-unofficial-aosip-aka-derpfest-t3978357/amp/
What would be the best way to downgrade/roll back to an Android 9 ROM? Safely.
Appreciate the help! Thanks.
I just did this process.
You just need to have your twrp updated and flash the stock rom (or other roms).
You'll lose your recovery, it goes to stock, and magisk.
I think flashing a non-stock android 9 ROM is way better, you won't lose your recovery.
If everything goes bad, you can try the unbricking tool for 5t.

So if I'm understanding correctly, it doesn't matter that I'm on the latest firmware as well? All I have to do is find a android 9 ROM (I'm probably going to do oos Aroma) and flash that in the latest recovery installed. Latest recovery being the one I'm currently on twrp 3.3
Yeah, that's it.
I was using aicp android 10 I just flashed lineageOS android 9, all worked well. I'm also using twrp 3.3 that should be OK.

How to update MIUI while rooted?

Hey guys, currently I'm on 12.1.2.0RJDMIMX with unlocked bootloader, rooted with magisk and TWRP installed. May I know the steps to update to the latest 12.5.1.0.RJDMIXM without losing data and root?
Back then when I was using OnePlus, the procedure to update while rooted was
Download latest update
Boot to TWRP
Flash Magisk Uninstaller ( not sure if this was necessary but did it anyways )
Flash the new update
Install latest Magisk
Reboot
Is the procedure same as for MIUI? Thanks in advance!
