So I couldnt wait for the answer so I decided to go ahead
with channel: 20.04 dev
all three checkboxes checked

Now I am stuck at this screen

I am using windows 10 machine

This is the correct setup options

@beyolf Apologies, didn't realize it was on stable with Focal now. I have too many devices and get mixed up :anguished_face:

What I have found if using windows is:

Install Android Studio - it will give the latest ADB and fastboot drivers which solves and awful lot of issues with device connectivity to the PC.

I have also found that some devices don't appear to boot into fastboot mode. Tapping the power button usually gets it going...

And be patient, especially with Xiaomi devices.

dont worry at all, you dont need to remember all the devices states

that is probably a good solution, it is really annoying on WIndows when you device is recognized when it is in bootloader , but it is not when you enter fastbootD... On miatol, 4 people had that same issue when installing from windows ...

MrT10001

@beyolf Ah, I forgot about fastbootD, I haven't used it in a long while (dm-verity ). When I have downgraded a Pixel 3A ROM, I used the Android recovery tool in Chrome which allows it to be disabled.

(On a side note Xiaomi phone hardware is good, but being forced to wait to unlock the bootloader of a device that you have bought and paid for is wrong, not withstanding the hoops you have too jump through to do it.)

@MrT10001 yes, I hate that aspect of Xiaomi devices too. But they are usually quite affordable and good HW wise as you say and still at least allow you to do this officially. There are far worse manufacturers around which only sell completely locked phones. So to translate you buy something which you are never going to own. Like Huawei or Realme brands.

Can we install Touch os on redmi Note 9 ?

Its not 9s or 9 Pro or pro max

Just simple note 9
is it possible ?

beyolf

@nibzy26

There is Xenial port for note 9 , but it's no longer maintained, but I guess it won't be hard to pick up that port and make it work with focal if you are willing to do it.

Best of luck!

while on the phone under storage it says 114GB Free.
any idea how to fix it

Thanks

Apt install packages on the system partition not on the user partition, the system partition is relatively small.

You can resize your system partition from fastbootd, but using apt and resizing the system partition is not recommended if you are not confident in what you are doing.

Edit: The maximum size which i managed to use for system partition without deleting other partitions was : 3900000000

in fastbootD execute

fastboot resize-logical-partition system 3900000000

then reboot the phone and in phone terminal or adb shell execute:

sudo mount -o remount,rw /
sudo resize2fs /dev/dm-0

this is the wayt to resize the system partition hope that helps
