Question Help needed to return to Android 12 stable

[HellStorm666]

I opted in for the beta of A13 with my Vivo X80 Pro (Europe version).
The battery drain gets worse every week.

Now I found out that to downgrade to the stable version, I need to send the phone to VSP Data.
That is on the other side of Europe for me.

So, I want to downgrade it myself.
How to do this? Because all the tutorials I found online are outdated, incorrect or incomplete.
At the moment PD2185BF_EA_A_13.1.11.7.W30 is installed.

I did a lot of custom ROM with the HTC HD2, Samsung S3 and Xioami's before. But cant get this simple downgrade to go

Who can guide me with a complete tutorial and working drivers (for Windows 11 Enterprise)?

If you have the Mediatek version, you may have some luck experimenting with mtkclient. We do such downgrades on 1+ Nord2 without bootloader unlock, so it might be possible to do something similar here as well.

If you don't think you have the chops to figure it all out, wait till somebody with your device does though.

The EU version (W30) is the Snapdragon variant.

Welp, if the official instructions don't work for you (people have mixed success with it), you're indeed hosed and you'll have to send it in.

I suggest going to the service center if there is one in your country. They can downgrade it there.

Or just wait until stable or more capable beta versus on of A13 is up.

Sorry if someone already mentioned this but have you tried the Vivo downgrader computer application? It's the only thing that let me downgrade. I do have the Chinese version though so I am not sure if it only works on that.

This looks to be a Chinese program.
I'm afraid it will brick my phone since my ROM is EU and not Chinese.

Does Vivo not have service in your country? I also tried donwgrade, but unfortunately I didn't find any working tools, ROMs, or procedure....

I have the same FW version as you and I have no battery problem. Check your apps. Often some update with gplay fails and then there is excessive consumption.

They did, that is why I bought the phone.
But after 2 months they stopped.

Never a Vivo phone for me ever again.

It works fine. I used it myself to downgrade to A12

I tried to run the tool just now.

Google translate says that it says "there is currently no version to downgrade to"

Ahhh I'm on Chinese version of the phone. Origin OS.

So... it gets even worse.
UK site has a newer version of A12 (PD2185F_EX_A_12.0.14.1.W30.V000L1) of the 16th of December.

And the 'local upgrade' function on the phone worked. (for the first time of all the tries).
But after the restart, it said the upgrade failed because the installed version is newer.
