At the last step (Installing /e/ from recovery => adb sideload e-0.14-p-2021012798470-dev-violet.zip),
I receive the following message
error : This package requires firmware from MIUI 9.5.14 or newer. Please upgrade firmware and restart and retry!
Can I solve this problem, I have no backup , nor other ROM for my devices. And if I try to reboot , the device is rebooting continuously …
How can I proceed?
To solve the issue of “This package requires firmware from MIUI 9.5.14 or newer. Please upgrade firmware and restart and retry!”
I’ve applied this solution : community.e.foundation/t/redmi-note-7-pro-violet-couldnt-flash-the-rom-zip-treble-compatibility-error/12940
To summarize :
1)Unzip the e-0.14-p-2021012798470-dev-violet.zip
2) Delete the file compatibility.zip
3) Go to …\e-0.14-p-2021012798470-dev-violet\META-INF\com\google\android
4) Open the file updater-script with Notepad++ (https://notepad-plus-plus.org/)
5) Delete the second line
6) Save and close the file update-script
7) Go to …\e-0.14-p-2021012798470-dev-violet directory
8) Zip the solution
9) Follow the instruction from “Installing /e/ from recovery” : doc.e.foundation/devices/violet/install
And it works for me
I don’t understand what I did, I’m newbie, I just followed the instructions … Now I’d like to understand from the begining (twrp, fastboot , …)
You’re facing a firmware level check, maybe inherited from LineageOS.
To ensure it will run smoothly, an Android ROM must relies on firmware at compatible level.
So the installation script includes a firmware level check.
Older firmware may run your Android ROM without noticeable problems, but you’re highly recommended to install latest firmware or the whole MIUI.
Because of this problem, in case of an /e/ OS update in the future (that I accept to do), is there a danger that my device doesn’t reboot correctly and that I loose my data ?
If yes how can I solve this ? Open an /e/ account ? other ?
Are there /e/ OS OTA update ?
Thanks.

It’s unlikely you will loose data, but your phone can misbehave in some unpredictable ways …
If it’s currently booting ok, this may not change unless you apply another ROM or upgrade (please see at bottom about updates and upgrades).
If you wish to upgrade your baseband, I think that the best path would be to :
backup all your data, record installed apps
flash latest MIUI, ideally at the latest level (YOU WILL LOOSE ALL YOUR DATA)
perform a MIUI OTA update/upgrade
unlock the phone (YOU WILL LOOSE ALL YOUR DATA, again …)
install TWRP then latest /e/ ROM available, at first without modifying the install script
Alternative path, easiest :
backup all your data, record installed apps
within TWRP, flash latest firmware
cross some fingers, reboot phone, enjoy
If your /e/ ROM is official (you got it from /e/ downloads page), you will get OTA updates for the Android version you have (in example 0.14 Pie to 0.15 Pie).
But, most likely, not OTA upgrades (in example from Pie to Q).
