Can not install Samsung Galaxy A52 (a52q)

[vilibald]

Hello, I am trying to install latest eOS on the a52q.

1. I updated the stock system to the latest
2. got Odin 3.13 and 3.14 and the vbeta.img
3. Followed up to a point where I am supposed to use ODin to flash the vbeta.img but there I am conistently getting the following error.

<ID:0/003> Added!!
<ID:0/003> Odin engine v(ID:3.1401)..

<ID:0/003> RQT_CLOSE !!
<ID:0/003> 
<ID:0/003> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)

Any ideas what tihs could be? I double checked USB debugging and Stay Awake in the Devloper options. The vbeta.img is extremely small file 8KB so wondering if it is correct or not.

I did not unlocm the bootloader correctly, that’s all. Make sure you see the warning on the splash screen. If you don’t see it, the bootloader is not unlocked.

In this model the magic is that the toggle in Developer options is not enough. When booted into the download mode there is a need to hold the Volume Up little longer for the OEM unlock to be effective. Make sure that the OME Lock is OFF see the attached image.
