Update to 2.6.3 not indicated

Using /e/OS Settings
1

Hello,

I hope I’m in the right place.

I saw on the phone list that a new version (2.6.3) is available for the Xiaomi redmi K20/Mi 9T, which I have in version 2.5.
But my phone doesn’t offer me to upgrade to this new version 2.6.3.
I check the installation page: Install /e/OS on a Xiaomi Redmi K20 / Mi 9T - “davinci”
But! For the first time, I see that my phone needs a very specific “firmware” for this new update, which wasn’t necessary before.
On the installation page, there are 3 choices of firmware to install:

  • Mi 9T (Global) - V12.1.4.0.RFJMIXM
  • Mi 9T (EEA) - V12.1.1.0.RFJEUXM
  • Mi 9T (Russia) - V12.1.2.0.RFJRUXM

I don’t know how to find the current firmware version in my phone. I know the phone model M1903F10A, but I don’t know how to find the firmware version?
Then, I don’t know if my phone is a global or an EEA, how do I find out?

Thank you very much for your help and reply.

Maybe this page will help you with the variants Info about davinci variants | LineageOS Wiki

Well … that is what it required for a new install.

Maybe you can get a clue from Settings > About phone … you could look around … but tap on Android version will give some useful information.

Regarding an Upgrade … once you establish the correct variant perhaps you can find the “Guide” on LineageOS to

  • Upgrade to a higher version of LineageOS (e.g. lineage-20 → lineage-21)

… this may be useful in deciding what to do for /e/OS

Are you currently running eOS 2.5t? If so you can do a dirty upgrade to eOS 2.6u. At lease I was able to on my Moto.

Hello,

Yes, I have the 2.5t.

A dirty update? What’s this?

Thanks, I’ll have a look.

First I think what aibd means in his first reply that is the method for a fresh install.

I don’t know your level of experience but what you are basically doing is updating the recovery image and then sideloading eOS 2.6u. I first tried going direct to the sideload but I had to install the recovery image first by fastbboot. Then reboot to the new recovery tool 2.6. Again a least it seemed I did have to update my recovery on a Moto phone.

Once in recovery 2.6 you enable ADB, then go to ADB sideload the 2.6u zip file for your phone. I was able to do this without wiping the phone and all data was intact.

Ok Jets, thanks. I’ll try that.

So there will be no OTA update from 2.5 to 2.6.3?

No more T updates, you need to upgrade to U :

it seems. At least, on my smartphone I don’t have any updates.

On second thought, I’ll do a clean reinstall.
Just to get off to a clean start.
Besides, I like doing it. :slightly_smiling_face:

Thanks to the community for the fantastic job.

Community builds are not tested an thus don’t get OTA when version jump

I’m think about a web tool to ease such jump from T to U

But the best would be that these builds become official by contributing to maintain them

@freechelmi,

What is the difference between the community version and the official version?
I installed the version indicated by /e/OS. It’s the official version, isn’t it?

Great idea for the installation tool.
