Flash at your own risk. I am not responsible for any damage or data loss to the device during this process!​




Please use this commands

Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta2.img


Fastboot flash boot nord2_stock_boot_A07.img

I needed to get my Nord 2 back to stock.

I flashed your vbmeta2, stock recovery und your stock boot-image.

When I lock the bootloader then (which would mean "really stock") and reboot the phone I always geht this horrible message "chinese signs and image destroyed". If I reboot with unlocked bootloader the phone starts. So where is the problem? Wrong boot image?

I hope you have backup. Unfortunately, I cannot know which mobile phone version, software etc. you have

Does this help? Build-Number DN2103_11_A.12

I flashed your vbmeta2.img and nord2_stock_boot_A12.img and got from somewhere the stock recovery.img.

I read in an older posting that you have written that it is NOT possible to lock the bootloader again. That would explain it ....

You must flash vbmeta2 then boot.img
Dear friend, please help. As I understand it, you will understand this issue. I installed root magis and twrp. after reboot I caught bootloop. after stockboot firmware, the phone booted up, but wifi and bluetooth do not work. What do I need to do, what is the sequence of actions to restore the phone? (DN2103_11_A.14) EU.
I cannot install any otp_update, twrp gives an error, I am doing something wrong. Thank you in advance.

You must boot in fastbootd mode.. type fastboot reboot fastboot

Then works

My Nord2 is in a boot loop since uninstalling Riru (and then all Magisk modules from recovery), so I'm here, looking around how to unbrick it. Unfortunately I have no screenshots of the build and phone version of my phone.

How can I figure out the exact phone and OOS build version I'm on? I have access to TWRP recovery.

While in TWRP, adb shell -l says

recovery product:DN2101IND model:DN2101 device:OP515BL1 transport_id:37

This is very curious as i'm living in EU and bought the phone in EU. Is TWRP (twrp_denniz) reporting the correct phone version via adb? Regardless, I'm still unsure what OS version I'm on...

    Yes, but i not test to Upgrade
    I tested. You must flash without root, then can you upgrade @xirosiman

    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.

    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)
