hello @joao.matos

Install LineageOS on surya | LineageOS Wiki

Wot ?? downgrade Android version ??

Hum… I am not running eos. I am running lineage os. I want to install eos.
Maybe you want a more specific lineage version?21-20241230-nightly-surya
Baseband ss.at.4.4.c6-00071-rennell_gen_pack-3.30805.9
Build number: lineage_surya-userdebug 14 AP2A.240905.003 d1c444b7a6
Is that enough?

If that is a downgrade so be it, i want to run eos. Is that not possible?

Well … Install /e/OS on a Xiaomi POCO X3 NFC - “surya” (which you quoted) includes this advice

Download the required firmware for your model.

If you are not downgrading Android version, you are likely “good to go”

you can run U version (android 14 based), but be carefull about :

This /e/OS v2.7 version includes the Android security patches available as of December 2024.

same version advised on lineage wiki !

i think you can try, you may encountred signature dismatch, but it could be not an obstacle

How do i know if the eos version is higher than the lineage version? The eos file only mentions the major version (14u). Is that good enough?

How do i check the firmware version? Also if the lineage version is a month old, the firmware is likely to already have the latest firmware files?

What do you mean be careful? What should be careful about or what’s with that security update that could cause issues? Or what is that i should or not do?

.

in settings → about the phone → android version 14 → base band or something…

.

no :
in settings → about the phone → android version 14 → security patch date
This /e/OS v2.7 version includes the Android security patches available as of December 2024.

.

on some devices / brand-vendor, new SPL (securuty patch level) must not be older than previous → anti-roll back feature…

Long story short, the device is * M2007J20CG which, by way of guessing and faith i assumed G would be for global. Also because was already on a newer version of lineage and piero hint on the security patch.
Because it had lineage was already unlocked so, just sideload eos recovery and adb the eos image.

Thanks everyone
