@Eric-H It worked It was my fault — I had skipped that step because I thought it was impossible to downgrade the OS version. But it was actually straightforward to just execute the flash_all.sh. Thank you so much!

@scottbouch I use the camera on my Redmi Note 9 Pro Joyeuse. On Focal, the focus time is a bit long. But the results are fine. Sometimes (rarely), the camera is black and I have to restart it (the camera app, not the phone so it takes 2 seconds). On Noble, the camera has been improved and works like on Android: immediate focus and good quality photos. I have no issues with this smartphone, whether with VoLTE (in Belgium with Orange), SMS, MMS, sensors or Waydroid. I am so satisfied with it that I bought a second one (new) on Amazon and use it as a backup device and to test Noble OS. For UT, it's a very good phone. My only criticism is that I would prefer a slightly smaller size (like the Huawei P30, for example), but that's just my personal preference.

@Eric-H Interesting! Even the unblocked photo isn't so bad to my eye, but I see the difference. Thanks for pointing me to that! Very helpful to know the details before spending hundreds on one phone or another. Thank you!

@MrT10001 @MrT10001 Hello, I found my mistake. To copy files from my Android phone to my PC using ADB, I need to execute the adb pull command directly in my PC's terminal, without accessing the ADB shell on my phone. For example, to copy the Music folder from my phone to the Music folder on my PC, I should use the following command in the terminal with a simple USB connection to the phone: Code adb pull /home/phablet/Music /home/(Your PC)/Music If it can help someone copy hidden system files, it works too.

Hidden channels are a lot more likely to break or be broken compared to devel. They're hidden from users because of that. Usually used by devs to test big things such as for example right now the 24.04 Noble images.

@CiberSheep said in How to set Calendar Reminder Sound Volume ?: @AppLee it may be a bug. This doesn't happen anymore on dev channel it works for me by setting via clock app, via uVolman, alert and alarm settngs have no effect for me and on Xenial too

With telnet I have see it is a mount failure. On Telegram a man say to Put the .IMG file in data folder I have put boot.img and ubuntu.img, but I think ubuntu.img is sufficient. And now it work :beaming_face_with_smiling_eyes:

@MrT10001 and @Jules Ok thanks

@ikoz thank you all, I succeeded.

@Eric-H thanks, my questions now are being solved at first - do i have to flag this thread as 'solved'?

I found this on github, but i dont know if it works. https://github.com/offici5l/MiUnlockTool
