I have 2 problems with the rom:
The first is that the App Lounge fails everytime, for every application even foss ones from f-droid just download up to 100% then tells “Retry”, maybe a problem of the underlying installer. I tried to clear the cache and app data and connect with my own account but it didn’t change anything.
My bank app also wasn’t working, i needed to edit /system/build.prop and change ro.build.tags=release-keys and ro.debuggable=0. The official versions didn’t need this change iirc

Credit: Thank you very much @ronnz98 for building this new /e/OS-T 1.18 ROM.
Hello,
New owner of a Xiaomi Mi 9T, I had some problems with the recovery mode in Chinese, see here: Xiaomi Mi 9T Recovery mode in Chinese Help! - #51 by Fougor
I managed to install the Global ROM and the recovery is now in English. My android version is 13. I then installed LineageOS to test it, but I’d like to go back to /e/OS.
Is this possible? Because @aibd told me that going back to an earlier version would be dangerous.
Thanks for your answers and suggestions.
earlier version? The official LineageOS for ‘davinci’ is version lineage-20.0-20231231, also based on Android 13 like @ronnt98’s e-1.18-t-20231210-UNOFFICIAL-davinci.
An OS change should be possible without further ado. Personally, however, I would first replace the LOS recovery with the e-rRcovery.
All right. Thanks for the feedback.
But I don’t know what the e-rRcovery is and what it’s for?
Please explain.
I understand some things, but this goes beyond that. 
Okay, I get it. So it’s the /e/ recovery that installs and will be more able to install /e/OS.
I tried to download the e recovery, but alas, I found nothing.
Is there a download page? If so, where is it?
Thanks for your help.
it is not necessary, as recovery-e is the same as lineageos-recovery, only rebranded…
it should/must do the job (it is expected because its mission is to install such recovery compatible .ZIP)
you need to extract it from the downloaded /e/ .ZIP (it is included in it)
Thanks, I found it. I’ll install it tomorrow.
The vague wording «it should do the job» sounds to me like - I don’t really know, but theoretically it should work because e-recovery is like lineage-recovery, only rebranded. Well, it’s always worth a try.
excuse me, i am French and for us it is the same verb… “devoir” (have to, also moral exigence)
only temporal conjugaison variation “il devrait” (that is expected), “il doit” (it is forced to)
i have corrected
All good @piero, when translating our native language into English, misunderstandings can quickly arise.

I hope I’m in the right place.
I would like to thank the person or team who built this unofficial /e/OS for the MI 9T.
I no longer have any problems with my bank’s app.
Bravo and many thanks for what you do.

Hello, I have a question.
In the post above where you detail the installation of version 1.18-t-20231210, you write: “then move *.zip file to a USB-C stick using e-Dateimananger.”
What is e-Dateimananger?
Is it an app?
Thanks for the answer.
Dateimanager is the German word for Filemanager
Oh right, thanks for the info. It’s clearer.
