Use it at your own risk!
Please support the developer(s)!
Not working fixed please
does this work for daily use? and where are the instructions? all i see is a link to horizondroid OS? what has that got to do with /e/OS?
Hey @ronnz98
Unfortunately I didn’t get on well with the links (I was able to download the 1.2 GB image, of course).
I still remember from my Nokia that I have to load a bootloader with adb/fastboot and then install the image via sideload.
I didn’t understand the description in the XDA thread about “horizondroid”.
Would you please give me a “nudge” in the right direction?
I’m hoping that the eOS will use significantly less power: I want the good thing to be clamped onto my motorcycle handlebars and be my guide (sat nav ;-))

Hey @ronnz98
Leider bin ich mit den Links nicht gut klar gekommen (das 1.2 GB groĂźe Image konnte ich downloaden, klar).
Von meinem Nokia weiĂź ich noch, dass ich mit adb/fastboot einen Bootloader laden muss und danach per Sideload das ZIP Image installieren kann.
Aus der Beschreibung im XDA-Thread bezüglich “horizondroid” bin ich nicht schlau geworden.
Würdest Du mir bitte einen “Schubser” in die richtige Richtung geben?
Ich erhoffe mir vom /e/OS einen deutlich geringeren Stromverbrauch: Das gute StĂĽck soll auf meinem Motorradlenker geklemmt mein Wegweiser sein (Navi ;-))
LG

Es scheint so, dass OrangeFox ( Xiaomi Redmi Note 12 4G/Redmi Note 13 4G (topaz) build releases | OrangeFox Recovery Downloads ) eine Möglichkeit wäre, einen Bootloader zu starten, der die Installation ermöglicht. Kann es selbst noch nicht testen, da das Bootloader-Unlock-Prozedere über die Mi-Community mir eine Zwangs-Wartepause von 30 Tagen auf die Nase gedrückt hat…
Updates for /e/OS-T 2.3:
same sources, l suppose this might not work:

New sources (crdroid), better chance that it works I would presume:

Update:
I’m still serving my 30-day mandatory break. In 14 days I’ll be allowed to open the bootloader - hopefully…
I’m very excited to see if the Redmi Note 12 will work!
Chances are much higher when A14 version is available since the sources are updated for A14
can someone send me a step by step tutorial on how to do this? i’ve never messed with phones before…
and how to make a backup of the original os and restore it in case.
meanwhile 30-day-countdown done!
I tried two times to get the bootloader unlocked, both times I got the answer that contingent ist reached - I should try it next day…
I will report if I did next step 
Unfortunately, I am unable to get the bootloader unlocked. Everytime when I request it (xiaomi community), I am told that the quota has been reached and I shall try it next day 0 o’clock.
I would be very happy to know an alternative to unlock the bootloader.
better try A14 based build, though no guarantee that it will work:
Hi @ronnz98
Thank you for your hard work on the Redmi Note 12 4G (topaz) builds for /e/OS! Your contributions are highly appreciated by the community.
I have a few questions and requests:
Any chance of becoming official?
Are there any plans or possibilities for this ROM to become an official build in the future? It would be great to see this ROM gain official support, which could attract more users and testers.
Compatibility with Redmi Note 12 4G (tapas)
Since this build is for the Redmi Note 12 4G (topaz), can you confirm if it will also work on the Redmi Note 12 4G (tapas)?
Request for an XDA Forum post
If possible, could you create a dedicated post on the XDA forums for the Redmi Note 12 4G? This would help more users know about the ROM, understand how to install it, and try it out. A proper XDA thread could also make it easier for users to report feedback and support your work.
Thank you again for all your hard work and dedication!
No, this device is really challenging to build and I don’t even know if it really works since I don’t own the device. Any feedback is appreciated. For popular devices which are confirmed working I can do more or less regular builds
Thank you for the update!
I’d like to test it on my Redmi Note 12 4G (tapas). Could you please share the exact flashing steps? Specifically, I’m planning to use OrangeFox Recovery for the installation.
I’ll make sure to provide feedback after testing. Looking forward to your guidance!
Thanks again for all your hard work!
XDA is always a good source, I usually post the respective links in my builds.

Orange Fox Recovery:
XDA is always a good source
I tried to install this on Tapas by following these steps:
Booted into Custom Recovery.
Performed a wipe of Internal Storage, Cache, Dalvik, Metadata, etc.
Flashed the Tapas 1.0.4.0 firmware.
Flashed e-2.5-u-20241124-UNOFFICIAL-topaz.zip.
However, it is stuck on the Mi boot logo.
Hi there,
Had the same issue, but I eventually succeeded by using MiBypassTool then MiUnlockTool.
The first one does what was needed before the Mi Community step was a thing. It’ll guide you into installing older unpatched version of the Xiaomi Settings app for it to work, you can install it using adb.
The second script does the unlocking part, but you will still have to wait (7 days in my case).
Each script guides you very well in each step of their process.
Good luck!
Edit: forgot to mention MyBypassTool
Nice Hint!
Did You use the same Redmi Note 12 4G (topaz) or another?
Could we maybe compare the firmware version?
… which means that you where able to install /e/OS?
I succeeded unlocking the bootloader for the same model (Redmi Note 12 4G - topaz), however it was for installing another ROM project. But as I’m discovering /e/OS now, I could want to give it a try too!
