Magisk DO alter boot (or the recovery partition in some special cases). But it doesn't alter the system partition. That what systemless means
As said, to extract your stock boot image, you need to not be rooted.
Okay, then I misunderstood that, or rather, the original post. The suggestion to extract a stock boot.img using dd requires an entirely unrooted Nord 2, not the rooted one that's meant to be updated? That must've thrown me off. Thanks for clearing that up 🙂

Hi, I have root. I received an update DN2103_11_A.15,
Screenshot_2021-12-28-00-47-42-38_f7aa348215f5d566f9e4ca860f474209.jpg

but I don't know how to install it. I don't know what Boot.img file to use. I also don't know what vbmeta.img file to use? I assume that I will find the update file at /data/OTA-package/update.zip

When your phone is in normal on condition connect to pc then open cmd on pc type
adb devices (enable usb debugging I assume u knows that)
Now type adb reboot recovery.
In recovery now click Install form storage select update file falsh reboot
I did that 10 times now ? it always gives me the same Error that i posted first.
I treid reboot in recovery via adb and magisk..

I uploaded my boot.img and the update.zip and screenshots from my current phone.

When i try to flash zip in twrp: (Error Code from my first post in this thread)
Error Code:
E3005: "EMMC:/dev/block/by-name/boot:33554432:dev/block/by-name/boot:33554432:cd61df719208c3354289ff1250dd34b1d965ab76" has unexpected contents

How can i update can someone help ?
They boot.img in the attached files is the one i pulled from my phone using your commands.

In Magisk i have Zygisk enabled and have kdragon_safetynetfix_zygsik installed (dunno if this matters?)

does someone have ERROR 3005 when upgrading from A.14 to A.15?
or maybe someone has a update.zip directly from A.14 to A.15?

    Hi guys so Many users are facing issue while they are rooted and twrp installed on there phone.
    They can't able to Flash update through stock settings OR via twrp if they tries to flash it via twrp manually facing no wifi and Bluetooth.
    So here is the process to flash any incremental update via twrp just we need update zip, vbmeta image and boot image of old oos version respective to your new update means if. We are upgrading to V11 we need V10 boot img
    U can use following commands to extract your current stock boot img after connecting to PC

    adb shell

    dd if=/dev/block/sdc49 of=/sdcard/boot.img

    exit

    Note: Remember this process will replace your twrp and removes root to gain root access. We need to repeat twrp installation shown in the following tutorial
    You can gain root acess only by flashing magisk.zip file after step no 7 given under instructions but I didn't tested it yet.

    DOWNLOADS:
    1)Download update v11 from Telegram :

    2) DOWNLOAD V13:

    3) Download V14 update zip:

    4) Download A15 update zip:

    We can also download update in system update process. Just download OTA update and when we boot in twrp just click install and then go to following folder there you will find update.zip

    /data/OTA-package/update.zip

    Download vbmeta:


    Download boot.img:
    1) upgrade from v10 to v11(indian)

    2) upgrade from v11 to v13(indian)

    3)Upgrade from v13 to v14:

    4)Upgrade from A14 to A15:

    Boot img for nord 2 EU REGION :


    Instructions :
    1) Download all file from the link given under this thread place them at one place on your phone so it can be easily accessible when we boot in TWRP.

    2)Now to boot in TWRP use following root acess app called as advance reboot. Open it and click reboot to recovery
    Or you can use adb command after connecting phone to pc in USB debugging mode.
    adb reboot recovery
    3) when phone boot in TWRP click install tab now go to folder where we placed All files.
    4) click install image tab at bottom now you we see image files boot. img and vbmeta.img that we downloaded

    5)now select boot.img and then select boot partation and slide bottom bar after successful installation

    6)click reboot and select recovery phone will boots back to twrp( This step is optional)

    7)Now again click Install and find our old folder now select update.zip file and slide bottom bar it will take 2min for complete falshing of zip.

    8)now agian click install now click install image and select vbmeta.img

    9)Now click reboot system phone will reboots and take 10min.
    Now you are successfully updated and have new OOS 11.3 A11 version on your phone without any issues.

    Follow the video:

    New update A14 update process:

    HI. This is my 1st OnePlus and OxygenOS. I am now on DN2103_11_A.11 and OTA is available. It is DN2103_11_A.12
    Basically I can flash it from TWRP and I do not need to save and flash boot.img afterwards bec OS will be the same version. Is that so? Or am I wrong? And I have to follow threads instructions ?

    HI and thx. I have made TWRP backup, boot and vbmeta
    So I can first restore boot then flash OTA and then restore vbmeta, yes? (Version 11)

    Don't use backup boot image restore process.
    Just download above boot image given

    and vbmeta image given in. My thread

    And u r update zip of device of your region not mine

    First flash boot img then. Install update zip then. Flash Vbmeta done
