@stanwood said in Redmi Note 7 / State of play:
But in mine I had only one file: vendor.img
so, in fact it doesn't matter what there was on the RN7 before flashing UT, except that we need this vendor.img?
In my case, I thought, that the caller echo may be caused by the fact, that I had Android 10 (LineageOS 17) before flashing UT. So I planned to make a factory reset, install LineageOS16, and than with the installer again UT, and see if the echo still remains...
So, yes, I can recommend you to try to reinstall the original official rom (Android 9, NOT 10), then reinstall UT using the right vendor.img (see above).
should it really be the stock rom? Isn't https://build.lolinet.com/file/lineage/lavender/lineage-16.0-20200226-UNOFFICIAL-lavender.zip sufficient, @stanwood ?
I never used the stock ROM on my lavender. Flashed custom ROMs from the end of 2019, first crDroid, then lineageOS.
Found UT these days and flashed it 
But the non-lavender caller hears on echo 
done so far:
without success: the non-lavender caller still hears himself.
Also muting microphone does not work on the lavender.
Should I reinstall again, also with wiping the personal data? Or flash TWRP, make a factory reset including formating the data, and then perform the ubports installer again? How can I safe and restore the personal data (including the apps, their settings and storage data) on UT?
(The last firmware I flashed when using custom ROMs was fw_lavender_miui_LAVENDEREEAGlobal_V11.0.4.0.PFGEUXM)
@stanwood may I bother you again:-) Did also the lavender caller hear an echo? Or both the lavender and non-lavender caller?
In my case (OTA-18) the lavender caller has no echo, the non-lavender caller hears himself. Also the mute microphone does not work on the lavender. Should I reinstall again, also with wiping the personal data? Or flash TWRP, make a factory reset including formating the data, and then perform the ubports installer again? How can I safe and restore the personal data (including the apps, their settings and storage data) on UT?
thanks @AppLee for your reply.
I tried both the devel channel, and the stable. Even reinstalled (without wiping the personal data) to OTA-18. Without success, the non-lavender caller has an echo.
btw, @stanwood, what do you mean, that you have "no echo anymore since OTA-17"? Did you also have an echo on the lavender?
@stanwood thanks for your reply. Unfortunately this didn't help. I will try a clean install. How can I see on which OTA I am?
I installed UT on lavender via the installer. But a caller from Android hears an echo. Switched from stable to devel channel. UT was updated (version of yesterday), and also updated all apps. But still the same, echo for Android caller. I thought the echo problem was fixed. Can someone please confirm that there should be no echo. Should I reinstall UT? Or how can I fix this caller issue?
