If someone prefer, I've found a way to backup the various partitions without the need of a third party app or even without the need of root.

While in TWRP, use these commands in your adb terminal:
Bash:
adb shell

mkdir /sdcard/PartitionsBackup

dd if=/dev/block/sdc13 of=/sdcard/PartitionsBackup/nvcfg.img

dd if=/dev/block/sdc14 of=/sdcard/PartitionsBackup/nvdata.img

dd if=/dev/block/sdc23 of=/sdcard/PartitionsBackup/nvram.img

dd if=/dev/block/sdc16 of=/sdcard/PartitionsBackup/persist.img

dd if=/dev/block/sdc22 of=/sdcard/PartitionsBackup/proinfo.img

dd if=/dev/block/sdc17 of=/sdcard/PartitionsBackup/protect1.img

dd if=/dev/block/sdc18 of=/sdcard/PartitionsBackup/protect2.img

exit
You'll find the backed up partitions in the PartitionsBackup folder in your Internal storage.

---

You can find the directory of other partitions with the command ls -la $(find /dev/block/platform -type d -name by-name) and backing them up the same way.

Probably never due to Mediatek chipset
I don't really think that's true, we just need to request proper ROM support from Oneplus + We need some good developers that are willing to put the effort into it. So far, Oneplus has been insanely stingy on the open nature that they preach.

All we can now do is wait and see what happens, or of course wait for a good developer to kick some ass! I've already seen some forks busy with lineage os.

Hi, do you know if it is possible to relock the bootloader in an easy way? Because if I use the fastboot command I get an error and I need to unlock it again to be able to boot correctly the phone. Is there a way like MSM tool for OP 6t (my old one)? Thank you

Hi
I wanted to go back to stock (from lineageos). I followed the steps
1. backed up the 7 img files (as i Post #82)
2. downloaded and extracted Oxygen 11.3 DN2103_11_A.07_images.zip
3. copied the 7 backup-img-files to the same dir as the extracted ones
4. connected phone to usb
5. adb reboot bootloader
6. run "1. ROMinstaller.bat" > Choice 1 > YES > Choice 2 > YES (install root/twrp)
everythin ran fine, exept the file "my_preload.img" wasn't found. i don't know where this file should be?
7. rebootet phone
now it hangs on the screen "current image(boot/recovery) has been destroyed...
when i boot the phone with Volume Down & Power, theres a small "RECOVERY MODE" on the button. but the phone turns off just after a few seconds.

That usually happens after flashing the wrong boot image.

I suggest you to flash the full stock A.07 firmware, and then directly flash all the OTAs up to A.12, without rebooting in between. And restore the 7 partition images at the end.
If needed, you can find most of stock boot images in this post.

Woah, thanks a lot. After these steps, it booted to stock ROM, thank you very much!
(saved my life, was my wife's phone :eek: :ROFLMAO:)

Can anyone tell me, what i did wrong? What do you mean with "wrong boot image"? I used all the Files from the Download from Post #1 and my Backup.

I've seen both Indian and Global boot images going around for this phone. Flashing the wrong one will end up in your phone not booting up, but it's just a matter to re-flash the right one after. Just gotta be careful

In this case it was just a matter of the phone re-locking after flashing the full firmware btw, not an issue

hey guys, I want to root my new OP Nord 2 but as I'm fairly new to the topic I wanted to confirm a few things before proceeding and potentially doing something wrong.

First off: I already unlocked the bootloader and I'm on build DN2103_11_A12.

If I understand the process correctly, the next step would be to patch and flash the boot.img. I've downloaded the archive posted kindly by sakarya1980 on the first page, which also contained the already patched/rooted boot.img for A12, which is the version I'm on. So now I just would have to rename nord2_magisk_boot_A12 to boot.img and flash it using the following while in fastboot mode:
Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta2.img


Fastboot flash boot boot.img
At this point I'm not sure where the vbmeta2.img and boot.img have to be, but I guess at the location of my adb/fastboot files on my pc?
Are the steps above correct so far or am I missing something?
Thanks in advance :)

The steps are correct.
I just reccomend to extract your own boot image with the commands indicated on this post, patch it with the magisk app, and the flash the patched boot image through TWRP. (it's the reccomended way indicated by Magisk dev)

Thanks, looking through the linked thread I finally found the piece I was actually missing: TWRP recovery and the app itself. Using the recovery I was able to backup my boot image (although I was a bit confused at first because the backed up files comes as an .emmc.win file), patched it and flashed it. Now my phone's successfully rooted :)

Friends, tell me again caught bootlop on download. (version DN2103_11_A.12 EU) root (magisk) . Root was getting to activate vowifi. Today the phone is dead to zero. and I didn't want to load, the white circles were spinning endlessly. Only a full reset helps, but this is not correct, until the first discharge or reboot. Tell me, maybe it can be flashed in full, or something else to do... but how to do it, I can't find the firmware? I would appreciate your help
