I'm an electronics engineer. I am mostly interested in embedded systems, low-level software development, digital signal processing , digital and analog circuit design, Real Time OS, Linux. My object is to be creative and innovative in the field of embedded system design. Currently working on Focal port for miatoll devices

Hello guys,
I am trying to continue the work of the previous porter for this devices and bring focal to miatoll devices. I will post here if I have any progress. So far I am setting up the enviroment needed to build and getting familiar with what needs to be done.
I do not have problem that you ping me. i simply dont understand why you pinged me thats why I ask.
I will try to explain simply how it works. Vendors which manufacture android phones, put their proprietary drivers and i vendor partition on the Flash memory of the device. We call this proprietary drivers "vendor blobs". Halium based OS as UT , Droidian and etc, use Halium as abstraction layer between the OS and the vendor blobs. What developers which work on halium do is reverse engineer how Android setup the vendor blobs and implement that in the halium project, then third party OSes (as UT , Droidian) use halium in order to provide different functionalities as telephony,wifi,camera,flashlight and etc.
If you want to gain deeper understanding on how exactly that is done and how halium works i would suggest to read the documentation.
In terms of VoLTE the IMS implementation is not standartized so the different vendors implement IMS functionality in different way in the vendor blobs. What we are trying to do now is reverse engineer how exactly Android communicate with the different vendor IMS drivers in order to setup the IMS functionality."
For telephony UT and other halium based OSes use ofono. Ofono have few different ways to communicate with the vendor blobs in order to provide telephony. The most recent method for achieving this is through binder (Android IPC). So ofono uses binder calls in order to communicate with the vendor cellular module. So what we are working on is understanding what binder IPC calls does Android do in order to setup the IMS for the different vendor blobs and implement that IPC calls in ofono. Sailfish OS already made IMS ofono extension for qcom based devices but this extension is proprietary and not open source.
As you can see from the explanation above the problem with VoLTE is not OS specific, but the problem is that the VoLTE vendor implementation is not standartized and for the different vendors a lot of tracing has to be done in order to understand how exactly android setup VoLTE and replicate that setup procedure in ofono for the different vendors.
Hope that brings some clarity on the subject.
Small update: I managed to build successfully the focal branch of the miatoll devices(YAYYY). Later on today i will try to boot it on my phone and see how it goes. I will post an update when i have more information to share.
Hi all, I got involved with UT from about a month and I love the project. I am electronics engineer and I am interested in helping as much as I can with development of UT , because I support the projects idea and vision.
I am currently maintaining focal port for miatoll devices, but I wish to get more into system development and plan to do another port too.
Thank you all who are working and supporting UT and making it real.
Update: We got focal running, most of the stuff work so far, i will perform a bit more testing and then i will upload it so everyone else can test it too. I guess a couple more days and it will be up for everyone.
The problem with windows is that when the phone goes into fastbootD the windows does not recognize it and you have to set up the driver from the device manager, then the windows will recognize the device and the UT installer will continue.
I am glad that you managed to install it from Linux and hope you enjoy.
Hello guys,
Small update . There is RC channel available now for miatoll devices, also when focal OTA-3 comes out there will be a stable channel too.
Have a great day/night.
Hello friend and welcome to he UT community! I hope you enjoy your stay here!
Redmi Note 9 pro devices are named miatoll and there are 4 separate devices which share that name, but have different codename:
This are the miatoll devices which are currently supported and maintained by the Redmi note 9 pro (RN9P) UT port.
Redmi note 9 pro 5g is a different device with different codename and its not currently supported by UT.
Hope this information clears up a bit the supported devices. If you decide to buy a miatoll device for UT please make sure it is one of the mentioned above and if you have any trouble with UT for this devices please let me know.
Best of luck and have a great day!
Hello @Kamikaze
We have some progress on VoLTE and I hope I would be able to share more details soon.
Another very nice community member made a telegram group for people which wish to follow the progress of the miatoll devises and help with testing or development. Here is the link if someone wants to join us and help.
@stanwood yes I took a look on the fix. Thank you for notifying me. The fix will land on OTA 5.
@stanwood thank you very much for the logs! I will keep you in touch!
I am glad you resolved the problem. Hope you enjoy UT.
@szocse1223 hmm that's interesting. Could you please collect for me logs from journalctl for repowerd service after the first reboot. I will try to reproduce the problem this weekend and fix it. Thank you very much for the report also.
@szocse1223 Hello, please excuse me for the late responce. I assume you have Redmi note 9 pro global/eu which joyeuse. May I ask you to try out 12.0.2 or 11.0.3 android version because this 2 are most well tested with joyeuse.
@Username112 sorry the ones I listed are for curtana not for joyeuse. I fixed my previous message.
@Username112 yes it should. This is a list of tested Roms for curtana( Redmi note 9 pro India):
Working firmware versions:
Curtana:
Just one correction , the UT port of miatoll devices is based on Android 10 not 9, so Android 10 ROM is (India) need to be installed before UT.
