Installation guide Redmi Note 9S

stanwood

@MrT10001 Thank you. Good to know indeed.
It seems there's an unofficial unlock tool that bypass the 168 hours waiting time, but I wouldn't recommand as high risks to soft brick the device. (I wouldn't dare).

I am using redmi note 9 pro global. I flashed the latest android 10 firmware at the suggested site. Then I installed focal stable and then focal devel. Rotation never. Should I try another android firmware rom?

@Cubiking As per instructions:

Reasons being is the device vendor blobs, stock partition sizes....

These devices have their issues, remember the porter is a)not being paid and b) doing it on their own time, so these issues may take time to get fixed.

@MrT10001 I mean, in the official introduction page https://devices.ubuntu-touch.io/device/joyeuse/ It says most features works. But in my case some refuse to work in my opinion. That's why I ask. I want to find the mistakes on my side.

Hi,
Is it correct for me to assume that you checked that rotation worked on android?
If not, it might be a hardware issue.

Also you mentioned redmi note 9 pro global, I'm not familiar with the existing models but maybe the global thing make it different...
I know some Chinese manufacturer send variants of a model with the same commercial name which drives me crazy and that's also a reason why I never attempted to port a cheap device myself.

Also can you confirm that you OEM unlocked your device (I think you did else installation wouldn't have worked).

Regarding your question about the firmware, it should be the one linked in the device page.
One important step to set expectations is to try the hardware in android before running the UBports Installer.

@AppLee
Rotation did work perfectly on android. I am just thinking if I should try another firmware. For example, https://forums.ubports.com/topic/7686/install-ut-on-xiaomi-note-9-pro/2?_=1716394641427
Obviously doesn't use the lastest firmware at the time of writing.

@stanwood Works like a charm. Thanks for this writeup.

@stanwood bought a second hand Redmi Note 9 Pro Global to finally move to focal. When trying to sign in to my Xiaomi account within the Mi Unlock tool (Step 2, first bullet item), I get stuck with 'Couldn't send verification code' in the 'Add phone number' form. Trying to enter the recovery phone number from within the phone settings Mi account, yields 'Something went wrong, try again (1001)'. Seems there is no option, to enter the phone number via the Xiaomi account web interface. Any ideas much appreciated?

@mschmids
Did you feed the phone number of the 9S smartphone?

stanwood

@mschmids Hard to say, as this went smooth for me. Did you type your phone number including the country indicative (ex. +41 for Switzerland)?

Also ensure your sim card is well inside the phone during this step.

Try to reload the webpage, clear cache and cookies from your browser, and try again.

@Vlad-Nirky yes, though in my case it is a 9 Pro Global, assuming that, except the specific ROM, the general process would be the same.

@stanwood the country code is actually selectable in a pull down menu.

Of course the issue is within the Xiaomi eco system. Not sure were to go from here. Maybe just wait 24hrs. Thank you both anyway...

Now all over a sudden the (recovery) phone number got added to my Xiaomi account. Actually I have been fiddling with different and finally the second to last versions of the Mi Flash Unlock tool, however I am unsure, if this is the real cause. But now I do not receive another verification code, when trying to sign in once again via the Mi Flash Unlock tool.

@mschmids
Mine is 9 pro global too.
With wifi disabled, i have associated the mi account easily.

Is there a way to install UT on the Redmi Note 9 without a Windows PC? (I only use Linux machines outside of work)

Cheers, Scott.

Yes, you can fastboot the correct ROM on. The only time you need a Windows machine is to unlock the bootloader which requires the Windows based Mi Unlock tool - someone has developed a Linux Tool to do the same thing (check this out). which I have not tried yet as Windows is just easier.

Thank you! Following the link (now confused) and reading your comment, I may be best to keep it simple and ask a friend for an evening of help with his Windows PC!

Cheers, Scott.

@scottbouch Xiaomi made it frustratingly difficult to unlock the bootloader. You have to log into your Mi account on the device , have a SIM card installed with mobile data and switch Wi-Fi off. Then use the Mi Unlock tool with the device in fastboot mode, logging into the the Mi Unlock tool with the account you logged into on the device, to be told you have to wait 168 hours to unlock the phone (7 days) and you have to wait, there is no way round it. Then when you have waited, boot to fastboot mode, run it through the Mi Unlock tool again with the unlock tool logged into the account used on the device to finally unlock the bootloader. Once that is done, install the Android ROM required( stipulated by the porter for technical reasons) and DO NOT relock the bootloader, set Android up again then install UT.

@MrT10001
There is another, maybe harder and more risky way to do it.
I have never tried.

@Vlad-Nirky Yeah, I linked to that and I haven't tried it yet......

I see that, within Global models, there are many different regional ROMs. Is it best to stick with the region that was originally on the phone (in my case EEA), or to use the ROM for the zone that one actually lives in (in my case, Global).
I see that @stanwood used Global (non EEA) in the instructions, but then I guess Switzerland isn't EEA, is it?

Or am I splitting hairs here and overthinking it?
