Question Phone Bricked : dm-vertiry device corrupted - verity_ctr

[allemandinstable]

Hi

I am very new to root
I followed the guide for rooting the phone from the pinned guide on the xda forum.
It worked prefectly, however I was getting a weird message in that the device was unsafe but everything was working fine and I thought the oem locking the phone might getting rid of it (I know it's stupid and caused problems) using fastboot oem lock

I now have the following error

Qualcomm Crasdump Mode
-----------------------------

dm-verity device corrupted
verity-ctr

Here's what I have attempted to fix this :
- getting back to fastboot and then using

1. - just booting the original
fastboot --disable-verity --disable-verification boot "/Users/allemandinstable/Downloads/9Pro_F75_Europe/9Pro_EU_F.75_boot.img"

2. - flashing it back
fastboot --disable-verity --disable-verification flash boot "/Users/allemandinstable/Downloads/9Pro_F75_Europe/9Pro_EU_F.75_boot.img"

but none of them work and still gets me the same error when booting



from the 9Pro_F75_Europe.zip which I downloaded [LE2123]

OxygenOS 13 F.75 boot : with Magisk v25.2
Untouched/Magisked (BA)

which was my version of OOS13 (F75)

- i looked for other threads and the unbrock guide bellow
the OTA zip files and stuff do not seem clear to me (don't understand) as I am again very new to all of this.

If anyone could help me unbrick my phone (and if you can explain me along the way what to do, how it works, etc...) it would be very nice of you, as I am pretty disappointed right now not having any phone.

Thank you

I think I expressed myself badly, I am from EU and this is the correct phone model (written at the back of my phone and also was visible in the parameters on the stock firmware )

I specified it to provide everything that could help at some point for people with better knowledge

the mistep was to fastboot oem lock after the root was completed ( which wa ssuccessful )

OOpsie, my bad ! (stress + non native english speaker might lead to some misunderstandings )
Thank you for your quick answers

Unfortunately, there is no download link mirror left for my device version [LE2123 - EU] ( following the link from @TheGhost1951 )

which prevents me from moving forward

maybe someone knows where I could find it ?

Thank you for taking some time answering me

There is no MSM for OOS 13, you have to use MSM for 11 and then update again to 12 + 13. Please read the guide I linked, it tells you all of that

Lol you saw the orange message that your device is not safe because of the unlocked bootloader and decided to re-lock it? You have to use MSM tool now.

After you get msm'd back to a working phone, get back to oos13 and root again, install magisk fully and then try this: https://forum.xda-developers.com/goto/post?id=88584503

That's a magisk module for removing the orange warning text. You have made a mistake that many of us have made before, welcome to android rooting

Thank you for your kind message, that's a weird sensation of feeling that stupid when trying out things.

Now I know that before doing anything, I will have a look on XDA Forums 🥹

Learned the hard way.
