[Guide] OTA update installation on rooted phone

This may be known to many but there are many users who were struggling with this.
Hello Folks,
Was getting few requests on XDA, Telegram and Facebook for this. As title says, there were few users reporting OTA failures while they were rooted with Magisk. Yes, that's obvious, it will fail as you have modified the boot.img (ramdisk) and stock recovery (Recovery_ramdisk.img) while rooting and installing TWRP.
Please follow below steps to update via OTA if you were rooted or using magisk.
Uninstall busybox binaries and Xposed framework (if you are using by any chance)
Uninstall Magisk (inside the app or by flashing the magisk uninstaller via TWRP)
Download update.app of your current firmware and extract stock recovery and boot file via Huawei extractor
Flash stock recovery of your actual variant as fastboot flash recovery_ramdisk recovery.img
Flash stock boot as fastboot flash ramdisk ramdisk.img
Boot to system.
Perform OTA update and reboot.
Root your phone again if you want.
Enjoy.
You could just :
1.patch the new ramdisk's update via magiskmanager then,
2.update via HuRUpdater without removing your root before,
3.then reboot straight to fastboot, and flash your new patched ramdisk
4.reboot to your rooted updated firmware with magisk module still working and root mods still applyied.
PS: I don't know about xposed frameworks

Do we need to keep "Enable OEM Unlock" checked or unchecked in developer settings?

Doesn't matter unless you are rooting

It should be hwouc folder directly under root of internal memory and not data/update/hwouc

"Could not do normal boot" after trying to flash TWRP

trying to flash TWRP on my S5 but when trying to enter recovery i get "could not do normal boot", "Secure download : Enabled", "UDC start"
looking online people seem to have problems with having Odin not recognise the device or stuck on the bootloading page but my issue is reserved to just not being able to flash the recovery.
I'am still able to flash CF Auto Root and the stock firmware via Odin. also tried to check if my bootloader is unlocked but does not show up as a fastbootable device (i already had twrp 3.0.1 and lineage os 14.1 so i would assume it already is unlocked)
sorry for missing any needed information
Hi , try to flash latest twrp recovery with Odin.
https://eu.dl.twrp.me/klte/twrp-3.2.3-0-klte.img.tar.html
If that doesn't help you flash this stock recovery with Odin , if that doesn't work download latest stock firmware for your device and Region and extract just recovery.img and make it as tar or tar.md5 to be flashable with odin .

Xcover 4s not patching boot w. magisk

Hi all,. for a friend I am trying to root a G398FN (PHN) with Magisk and a patched boot file. I went thru the unlocking process at the bootloader, I took the latest android Q firmware and with 7Zip Zs I unzipped the AP file, and then I got the boot.img.
Magisk says it is patched, then I use ADB to GET the file back on my PC, and then I flash it with Odin.
I have tried all sorts of combinations, flashing the patched boot alone, flashing the enitre AP file, flashing the patched AP file alone, and the complete firmware, but in any case I end up with a phone that should have a patched boot, but doesn't. Magisk is not a stub, and Magisk asks for the original rooting method.
Does anybody know what I am doing wrong here ? The patched boot is downloaded via ADB, then flashed with the latest Odin but the phone is not accepting the changes.
So i Have a Xcover 4s G398FN with android Q latest firmware, latest Odin, unlocked bootloader and I have tried almost every combination there is to make the phone work with the patched boot. What is happening here? Any help would be greatly apreciated.

Magisk Manager "No boot image found" to patch

I know two ways to get root access on Android.
use magisk manager to patch boot.img and then flash the patched boot.img
install twrp and use it to flash magisk directly
For the first method I have to get the boot.img from the manufacture's firmware. Using XperiFirm I downloaded the firmware my phone is currently running on but I can not find any boot.img file in it.
Looking at this Guide it says the boot_X-FLASH-ALL-A2CD.sin file is the boot.img file. But when I try to patch the boot_X-FLASH-ALL-A2CD.sin file with magisk manager then magisk manager says "No boot image found". What am I missing here?
For the second option I would have to install twrp first. But there is no twrp for the sony xperia 1 yet: https://twrp.me/Devices/Sony/

Question Latest magisk, it's updating

Just checking, has anyone tried the ota unroot then direct install after update method. With the lastest magisk released today?
I did adb sideload method and flashed patched boot img with magisk 25
