Hi,
Thanks for your answer !
With my phone in recovery mode, I used the command
adb shell getprop ro.build.version.release
And it returned 12.
So I am assuming that I am on Android 12… With should be good enough.
Indeed, my phone has most likely been recently updated. I just bought it on the website back market. I can assume that the vendor could have installed updates.
Is there a way for me to check ?
I am not sure to understand the issues with the Security patches…
But in short, I may need to wait for the e-1.16-r release, right ?
About Flashing additional partitions.
I used the file at this link
https://images.ecloud.global/dev/instantnoodlep/recovery-IMG-e-1.15-s-20230916331435-dev-instantnoodlep.zip
And I flashed the 3 img with the commands of the tutorial.
I am now realizing that between {dtbo, vbmeta} and {recovery} I did not reboot.
I will redo it just in case.
But I did not receive any error during flashing.
Edit: I did a boot loader reboot after flashing dtbo and vbmeta. Nothing changed
