Hypothesis! Replacement motherboard WM Shift.

Hi all. I am posing a new challenge with our Shift. This is to replace the part of this device WM motherboard. I would appreciate the collaboration on this thread and the contributions of disadvantages, problems and possible solutions for this somewhat complicated task of hardware and software but not impossible.
First thing that the who understand know the options (and so their advantages and disadvantages) is that the candidates to merge with the Shift are a HTC universal and a Toshiba Portege G810.
To get started on this I would like to provide ratings on basis of which of the two options is better in terms of quality.
Below, in my view, advantages and disadvantages of both devices:
HTC Universal;
ADVANTAGES;
- During the two years that I have used, I have not had any problem or original ROM or custom.
- Operation BT, WF, SDHC and GSM, GPRS, HDPA, etc... perfect.
- Already have physical and therefore port connection (advantage) keyboard.
- Headphone speakers and 3.5 mm stereo.
- Processor to 525 very stable MH
- And of course, is HTC.
DISADVANTAGES;
- Disadvantage, the motherboard is very large, and can cause problems to locate in the Shift.
- Very little RAM and ROM memory (although until now I was enough to have SDHC)
- Has no internal GPS antenna (is not a big problem)
- Impossible to install WM 6.5 ROM (this is not essential, but would be brilliant WM 6.5 and W7 Ultimate already installed)
Toshiba G810:
ADVANTAGES;
- I had problems with this device since change the original ROM. Currently with ROM WM6.5 (excellent for my)
- Excellent size WM mother board to join the Shift.
- Also perfect wireless operation.
- RAM and ROM perfect and perfectly withstand WM 6.5.
- GPS antenna internal and functional.
DISADVANTAGES;
- It has no physical keyboard (I think, not I have to remove it even, to see if you have physical port full or only for hardware that has keys). The know this weekend.
- Has no output 3.5 mm.
- No output speaker stereo.
- Processor to 400 MH (same as original processor Shift)
- Isn't HTC.

After this, a brief description of the problems that I think would resolve to operate the full Shift.
- Knowing the current Motherboard of the Shift operation voltage.
- Communication with motherboard PC, i.e. through the port mini-USB these devices? I think is the most logical.
- There will be problems with the operating system change button (toggle WinMO with W7)
- Port connection hardware (touch screen, keyboard physical, etc.)
- Button powering up Shift would boot WInMo or place hardware appliance's power button.
- Shift control Center official Windows CE C++ application soft reset, enable / disable modem, etc. Or would need to rewrite code.

This sounds like a monumental task and I wish you success. It would be cool if we'd be
able to replace the current WinMo side with a more functional Mobo, but alarm bells
start ringing when I think of how to keep functionality between the two OS'es.
By all means please keep investigating. I got a Universal to spare if the howto's are published some day

THX.
Lucid Hello. If you think that it is a task difficult, although not impossible. Nor do I think a better place and more solidarity to publish a project like this boot. Thank you to stop writing in this thread, and recalls that any comments or information will be valuable contribution. Best regards.
ivs..

I wish you the best of luck on this project.
However, I think the biggest challenge yet is to find a WM device with a motherboard that has the same dimensions and connectors as the one in the Shift. You can probably forget about using the Universal for this as the Shift has VERY limited space available inside.
These pictures from the FCC is showing the WM motherboard and placements of connectors. You can compare these images with similar ones from devices like the Universal.

That's strange I didnt remember that SD reader was on WM motherboard part..
Anyway let us know about your progress
Edit: it's late sorry it was SIM reader

That's because what you see in the picture is the SIM-card slot, not the SD-slot

Hello and thanks for the interest and moral support. And in particular thanks to Deadnex for these images. I came very good to view the port connection of two boards, as well as the distribution of different items of hardware to keep in mind. Really, thank you Deadnex. Only one thing more, I could indicate the source from which to get the images, please?! There are more images?
Well, on the other hand, thanks to this graphic material, haven't had to wait to completely dismantle my Shift (is my utensil working more essential and.... UFFF, best dismount when this all OK), jejejeee....
Now a small summary of what I have been figuring out through the above grateful now:
Firstly, to apologise for having my careless thread, but closing the year with regard to work this still apotheosic. Be grateful for your patience and understanding in this regard. Thanks a lot.
-Said, the first thing that is clear is that impossible to find a PDA Board with the same connector as the original, because it is an adapted and exclusive design for the shift. It is therefore more essential balance size or their distribution within the Shift that the connector (in principle).
-Moreover, the next task is the identify the purpose and distribution of each connector pins (not must be hard, follow the path of the plate). That is, in one of the images provided by Deadnex, identified 60 pins unless escape me something or not can see in the image, these should correspond to the keyboard, screen, sound of the PDA, connection to PC connection with PC and PDA via the PC Board power port USB headphones 3.5 mm audio output (although I think that this can be two tabs that are seen in the image).
-Also there are other elements of the PDA Board I have not even clear hardware. Tonight i posted image stating what I mean, to see if someone has light to contribute.
However, as I said in the first post, any contribution can be valuable, for example, specify the operating voltage of the original PDA Board and the part of the Shift PC SDHC slot. I am quite concerned that.
But all that leais this thank you, and those that aporteis something, because even more thanks. Jejejeee
Happy holidays to all and happy new year.
A greeting.

[KERNEL][ICS][anykernel] USB Host mode (OTG) driver for Nexus S [BUILD 5]

USB Host mode driver for Nexus S
Also available on the Samsung Captivate and Samsung Galaxy S​
(main post and more info at the SGS dev site)​
Disclaimer: This kernel will enable some very early, and rough usb OTG support for your phone. Currently the phone DOES NOT give out power, so you NEED an external power source to be able to use this kernel. This is true for ALL USB devices, even with those that have their own power source, and doesn't requre external bus powering. Solving this limitation is a TODO, but we cannot guarantee anything. There are some other phones that have usb host support the same way this kernel has (eg. they need external power), like the Nexus One, and there is also a community using this, so if you're saying that usb host support has no sense if you need an external power source then you are definitely mistaken.
This kernel is built upon the official ICS kernel from google's git repository. It is possible to port this to older ROMs (like CM7, or stock Gingerbread). Ask your favourite kernel developer to do this for you.
Credits goes to:
The misterious guy at Samsung(?) called chul2 for the original s3c host drivers
Kevin Hester (kevinh, probably also nicknamed geeksville, punkgeek and humcycles) for fixing the s3c host driver for the Samsung Galaxy Tab
Ever kernel developer at teamhacksung for bringing ICS goodness to Galaxy S
This is a very early, and very rough usb host support. Expect crashes, freezes and things that are not working! You will also need external power (probably through a Y-cable or a powered usb hub, see the device connection guide below). Also make sure you are only using USB 2.0 (high-speed) devices. The driver does has some quirks with USB 1.x low-speed and full-speed devices, like mice, keyboards and similar things. Read the FAQ for more information about them. And of course it doesn't work with USB 3.0 (super-speed) devices.

Interesting! Following.

Holy crap, got to check this out in the morning :-D

Thanks sztupy for porting this to the Nexus S!
I flashed your Kernel to my Nexus S (i9023). First of all it does boot, everything seems to work, did not brick my phone
The Nexus also found my hub in way, but i couldn't see any devices. But i won't say it is a problem with your kernel, i think it is more a problem with my insufficient wiring because i have not enough cables/adapters yet, but i will get some this week, so i can do more testing then!
So here is what UHC showed so far:

It does work on the Nexus One with an usb monitor: http://sven.killig.de/android/N1/2.2/usb_host/

this is awesome !!

If this works, we have video output and USB input via the USB pin right?

ok....a noopie question , what is this for ?
just make phone like computer which can control other USB devices , like extrac pictures from Camera and something like that ?

It would enable you to connect any storage usb storage device to your NS, think usb drives, memory cards, external HDDs.

Works, but wifi doesn't work. Will this work if I just use a usb micro cable then a f-f coupler with a powered hub? I made a CWM installable package - attached below.

they weren't in the right position. I think they have to be in /system/modules/driver.ko instead of /system/lib/modules/driver.ko
I moved it, but it still wasn't working.

I briefly tested out the flashable version compiled by Epic_VS. My setup was with a micro USB OTG connector and an externally powered hub. I also tried my own hacked together USB cable, in place of the OTG connector.
In short, I was only able to get the message "Root hub found". I tried connecting a mouse (which I know is usb 1.1, but I thought I'd try anyways), a 360 controller, and a few different USB thumb drives. None of the thumb drives showed up as listed devices, and they did not show up in the mount point under /mnt.

I don't think that would work. You'll need to make sure that the unused pin on the micro USB side is soldered to its ground pin (as seen here: http://forum.xda-developers.com/showthread.php?t=1068197

someone tried if it works on ROM KANG CM9?

I made one and it works. If you read his sgs thread, he said cables without pin 5 grounded will work in host and auto-host, but not in otg mode. I got a flash drive to show up in the app, but it would not mount to /mnt/ehdd/
I attached 2 pics.

Hello, Huawei E3276 works with Malaysk's rom.
I have a Huawei E3276s-150. First I'd accidentally updated it with the HiLink firmware (22.470.13.00.00), but I've found a post where people said if I navigate to 192.168.1.1/html/switchProjectMode.html I can switch it back to normal mode. (You may have to try the URL a few times, if it doesn't work for the first attempt.) In normal mode I was able to flash the 21.491.03.00.00 firmware. I think it might be a solution for people with E3276 HiLink modems. Then I'd set modem only mode with AT commands, using Tera Term. (Check this out for modem only: http://superuser.com/questions/586049/how-to-force-a-huawei-e3276-lte-modem-to-only-mount-as-a-modem)
Now if I connect the modem to the HU it connects to 3G network in a few seconds.
About unlocking huawei modems, well, google it, it costed me a google +1. Totally worth it.

This quote is from the Uber Mega Huge Thread Huifei
I can't make mine work as it came to my hand, I still don't have the modem symbol as @dsa8310 so many times said. Already installed PPP Widget, PPP Widget 2 and Mobile Network Settings. All of them alone, or together with each other or all, with or without Externally powered Belkin F5U404-BLK USB hub in all USB ports from the radio. Does someone knows something that might do this or other hub not work with the radio?
Next step is the dongle's firmware... The quoted above post points to a link that might not be avaiable in the future, so I'll also quote it.
How to force a Huawei E3276 LTE modem to only mount as a modem?
I have a Huawei E3276 LTE USB-modem and I need to force this modem to only mount as a modem when connected to the computer. Per default, the modem also mounts as a CD-drive and a USB mass storage device, which is fine when used with a computer, but a problem when connecting it to a router or similar.
What I've read so far is that you can use PuTTY or similar to connect to the modem over the COM-port, and then send AT-commands to it to configure the modem to only mount as a modem. The AT-command mentioned for most Huawei modems is AT^U2DIAG=0 but when sending it to my modem I receive ERROR in response, which doesn't give me much to work with.
I've also tried AT^U2DIAG? which is said to work for some Huawei modems to display the possible values for this property, but that returns ERROR as well.
I've tried other AT commands, like ATI to get information about model, IMEI etc. which work just fine.
Is there some other command I can use to do this, or is there something else I need to do in order for this to work?
Click to expand...
Click to collapse
You can use these AT-commands:
AT^SETPORT? - show current mode
AT^SETPORT=? - show available modes
AT^SETPORT="A1,A2;1,2,3" - set "only modem" mode.
Make sure you write down the current mode (using the first command), just in case you want to revert any changes at some later time.
After sending these commands you have to reinsert your modem.
Click to expand...
Click to collapse
You should use this command
AT^SETPORT="FF;1"
This command disables all ports excepting the modem port.
I guess you have already solved your problem but I hope this will help other users having the same problem, since I have spent a couple of hours trying to find the solution.
I have a HUAWEI E3131 modem (issued by RCS-RDS in Romania) and now it works with a Edimax 3g-6200n router

@anyuzo do you have recommendation before I start playing with the dongle's firmware? Mine is already unlocked. Do you think I might have benefit in test it first, in modem only mode first? What's the difference between Hilink and Normal firmware? I found a page that has a very nice amount of Huawei's firmware but it doesn't have the version 21.491.03.00.00. Do you still have it? Can you share it? Google only points to Russian or Polish sites... I can't read cyrilic alfabet... yet

I'm glad it worked out.

I screamed victory to soon, the connection falls after a few seconds. Adding the USB hub make the radio not recognize the dongle... I guess I need a different hub...

Because ultimately the objective is power the USB ports with a Dc-Dc 12v to 5V converter, and my ports connect to the radio by this cable
My idea is power the USBs directly in the cable; disconecting it on the plug, and connect the wires to the converter. 3A should be enough to the dongle
Here is the one I bought

Ok, after dismantle a 700 mA car cigarette adapter to directly power one of the USB plugs I arrived to the conclusion that it's almost the same ending. Even with the dongle directly powered, 2 things usually happen;
1 - The dongle's blue light stays fixed saying the dongle is connected, but google chrome says no internet.
2 - The dongle's blue light stays fixed saying the dongle is connected, but after a couple seconds the connection falls to blinking again and the reconnection doesn't occur.
Before I wasn't able to add an APN, now I can. ( Apparently it means the HU already detects the modem. )
Any input?

700mA might not be enough power to run the dongle. I would use at least a 1 amp or 2 amp power source and try again.
The dongle should only draw as much power as it needs.

You are completely right. I had to tear all apart again, and again cannibalize other 1A adapter but even tough it's not perfect. PPP Widget is unable to auto connect and the connection lots of time must be restarted, not sure if is lack of energy of it's a network issue.. I'm waiting for some ebay 12 to 5v converters with 3A to try it again.

For any one who wants to do the MTC Sound MOD on the KD-C0250 here is how I got it to work.

USB OTG with the MI Mix

Hey all!
Just got the phone and I'm loving it so far.
Recently I tried to transfer files over to the MI mix using a otg cable and a USB 3.0 thumbdrive. The miui did not respond to the otg plug in. However the file management app `esfile` detects the otg (pop up to ask for permission to be the default app to handle the drive), but upon opening the app, the otg drive was not shown...
Tried the otg setup on a nexus 6p and it works without problem.
Any pointers? Thanks!
Edit: I'm on the EU ROM

Thank God someone else has noticed this, i have been unable to get this feature working, however the MiMix does recognise peripherals such as USB mice but haven't been able to get it to work with any USB external storage options, would appreciate some steer from senior members.

Thanks for confirming the issue. May I know what ROM you are using? I think I jump straight to EU rom without ever testing the Chinese Stable ROM. I may flash it back just to see if it works.

Hi, I have the same problem, and I really need to copy files from my MIX to a USB drive for my clients. Any solution or workaround?
I am in the latest CH stable ROM, no unlocks or flashes. I've tried several USB drives ranging from 256MB to 32GB, all formatted with every available file system, but no result.

I would like to be able to utilize OTG as well, I'm on EPIC ROM 7.1.19 hope some one can figure it out.

I have used OTG Dtech with Mi Mix that is working fine, no problem.

I hadn't known there was an issue I was able to move data between the usb flash drive and the phone on mine.

okay, this is Xiaomi messing about and its so frustrating
I am one of the people using a non rooted phone with over the air updates
HOWEVER, I am part of the pre release group that gets roms early
Now, when I got my phone initially with Miui 6, USB otg didn't work
The pre release beta solved this, without issues, happy days
NOW THE WARNING
just upgraded to
Android 6.0.1 MXB48T
MIUI 8.7.3.9 Beta
Kernel 3.18.20-perf-g459b3d5-336479-gc53fe55
And they've killed it again
I am PRESUMING this is ( as I am fully aware, I am using Beta software ) that this is a bug
However, if this is on purpose, I am very frustrated with the reasoning ( or lack of it ) behind it

My previous pendrive was ExFat which is unsupported format for Es file explorer(as is pop up showing), once formatted it on Mix, now works on latest Epic rom 7.3.9.

Still trying to get xiaomi to agree boot unlock before I get the epic rom
Hopeful though, it sounds far better

I found if the drive isn't fat32 you will need a 3rd party app to interact with the files [I use exFat/NTFS for total commander - as it works on non-rooted devices].

Trying to do IT work on an internal network or something? Other than that or try to break into a hard wired network I wouldn't see a reason to even try to use a usb network dongle. There are MUCH better devices to do the other two things with than ANY android device.

Ha, yes I do IT work. I normally have so many cat5 cables around me it's better than wifi calling (most places don't have great wifi in their server closets) or att service for that matter
I used to use hangouts dialer to make calls over the network, never had reception issues with that method
What much better devices were you talking about? I'm curious now

For mobile IT I got a Viliv N5 a long time ago, loaded Debian on it [got everything working properly after awhile of fiddling] and now use it as my mobile trouble shooter [Kit of extra's in a bag with it].
http://www.umpcportal.com/2010/07/viliv-n5-umpc-full-review/

I have the verbatim USB SD card adapter, and a 128gb Samsung Microsd card.
I can open and read files in the Microsd card using the mix. However, when I try to transfer files using Explorer copy and paste in USB, transfer progress gets to 80-100%, then the UsB status goes to ejecting and checking for errors.
I have enabled developer options and install via USB. I have also enabled documents under installed apps.
I'm using official global stable rom and locked bootloader.
Any help would be greatly appreciated!!!!

I am assuming my USB external DAC issue falls along with this bug.
My Google Pixel works fine with any USB OTG device (DAC/USB Stick/ etc...)
But the Mix will not detect it even if I go into the developer settings and change the options like Xiaomi themselves recommend doing! This is so frustrating.

I got USB OTG to work with another adapter (Meenova). In my case my issue was adapter hardware related.........hope this information may help!

Hi there!
Well i cannot make otg wotk on my mix any way. I've just the one adapter and I do not know which type is it but I use it on my Nexus 5 no problem with a Sandisk Ultra USB 3.0 32gb stick... I've tried with all apps you mentioned in this thread and some more... It is not detected on twrp either.
Any ideas?
Thanks!

Android Auto not detecting Xiaomi Mi 6 with MIUI Global 11.0.3 (Android 9)

Hi all,
I've just bought a new car and its Android Auto doesn't detect my Xiaomi Mi 6.
I'm running MIUI Global 11.0.3 on Android 9 with Android Auto 4.8.594324.
I connect the original USB cable to the right USB port but nothing happens, both on car and phone. It just starts recharging.
I've tried uninstalling and reinstalling Android Auto on my phone and resetting car infotainment to factory settings but it didn't help.
I've enable Debug USB under Developer Options but it has been useless.
I've given to Android Auto all permissions: autostart, no battery restrictions and access to everything.
I have no cloned apps or cloned accounts.
The smartphone is already connected to the car via bluetooth and the connection works fine.
I know that I should try factory resetting my Xiaomi Mi 6 but I just did it for another reason and it's a pain in the neck.
Is there something else I could try?
Should I try cleaning Google Services cache? Maybe some other service caches?
Is there a custom ROM I could try? Something similar to MIUI or to Android One which is certified to work with Android Auto?
Thanks!

Regarding custom ROMs I found out there are several ones: https://www.getdroidtips.com/list-best-custom-rom-xiaomi-mi-6/
I could try LineageOS, I used to use CyanogenMod back in the days.
I've also found this that should allow me to install an Android Auto Development Head Unit on my PC so I can test if my smartphone is getting recognized, without needing to be in my car.
But I would really love some advices from you, guys, because these are all time-consuming activities I would like to avoid.
Thank you!

Weird, running latest Miui 11 on my Poco F1 and works perfectly in my VW Golf. You've done the correct things to put the program to autostart etc .
The time I tried a custom rom Android Auto was an issue and I immediately went back to MIUI.
Couple of things first. Can you try with another phone? Can you try with a different USB cable? I once had an issue with a cable I used.

That's really weird.
Today I tried with a Huawei Mate 10 Pro from a colleague and it immediately worked fine.
I'm trying with the Xiaomi original USB cable but I've also tried with another good cable from Anker, I have only another one left, I'll try that too.
Anyway, my colleague's phone has been detected when connected with the same cable, so I don't think it's the cable.
When I connect the smartphone to a PC or to Android Auto, using an USB cable, shouldn't the phone pop a notification from which you choose what to do? Recharge only, MTP, PTP, USB mass storage or similar?
I don't have it.

OK, so it's not the car radio or probably not the USB cable. Which car is it actually?
Mine asks for charge, ... ... yup the 3 things when connecting, but not sure if it is the same case if you switch on usb developer options. Does it go into charge if you plug it in?
Do the options show up if you connect it to your pc?
If you start Android Auto (lets call it AA) on the phone and go to -> settings -> connected cars ... does it show anything? or is 'add new cars to AA' switched to 'on'?
Not sure if AA works in safe mode. From what I've read on the internet
-Press the power button till we get pop-up window.
-Then press the restart untill you get a popup to boot in safe mode.
-A restart will take take and your phone will be in safe mode.
There are some emulators on Windows and I use a raspberry pi if I need to play and don't want to go to the car all the time which might make it easier to get it running.
I know 1000 things and it can drive you crazy.

The car is a Skoda Karoq from 2019.
The smartphone correctly starts recharging when connected to USB.
When connecting, the three options don't show up. I've tried connecting it to a Windows PC and to a Linux PC, same results.
Doing this test on Windows, I've noticed I'm having issues connecting the phone to a PC and I'm receiving an error "USB device not recognised":

I think this could be the root cause of my AA connection problem.
I've replaced the Xiaomi Mi 6 USB port few months ago, since it was broken, and maybe the new one is unable to bring up a data transfer.
I'll try to reset my smartphone to factory reset to see if it's a software glitch but now I'm pretty sure it's an hardware one.

Good advice, I wasn't aware of that!
I'll keep that in mind.

No, unfortunately it doesn't show anything. Add new cars to AA is on.
I'll let you know how it goes with the USB connection to PC test!

Skoda Karoq, nice, probably the same unit as in my VW.
Well I guess you found your issue. No data via pc will also be a no go for AA since the data of the screen etc also seems to go through the USB interface.
A thing you could try, try to put the phone into fastboot. Normally you will need other drivers .... but I'm afraid it will be the port itself which is broken or not communicating like it should.
Does it even fast charge? Normally a charger negotiates via the data lines what the output will be (referring to QC modes etc)
Seems you are techie enough to get a charge doctor / usb tester on like aliexpress for a couple of euro which will show more.

Yes! It's probably the same unit, rebranded, with a different UI

Trying in Fastboot is a good idea but I think you're right when you're saying it's the port iself.
I fixed this Mi 6 myself, since the USB port was broken, I opened it, replaced USB port and battery and glued it back.
The phone recharges itself correctly and fast but I rarely connect it to my PC so the new USB connector has probably had this malfunction since I installed it, but I never noticed before.

I didn't knew these things even existed! :laugh:
Anyway, I think I'll quit testing and I'll buy a new phone, since I don't have time and will to fix this Xiaomi Mi 6 another time.
I'll probably buy a Xiaomi Mi 9T or a Xiaomi Mi 9T Pro.
Just to track everything, before finding out the hardware problem, I did some other useless tests:
I've enabled Debug USB under Developers Options;
I've uninstalled and reinstalled AA a couple of times, also deleting all its data;
I've tried with another third USB C cable;
I've uninstalled Car Home Ultra I was keeping on my phone as a backup for AA;
I've uninstalled Battery Widget 2019 Pro, just to understand if he was messing with USB connection.
Thanks lukesan for helping me with tests and pointing me in the right direction.
I'll come back here and let you know how this ends, when I'll have a new phone

You're welcome. And if the new phone also doesn't work swap the car too. . I personally would go for the Xiaomi Mi 9T Pro but that is me.
As per my advice buy one of those USB measure things. I highly recommend this RD UM34 or the C version. For 14 euro It has saved me a lot to take the guessing out of most things. I just had someone wanting to throw out her tablet since it doesn't charge anymore. 4 years old. It's just a cable issue, the battery and charger are fine.
Want to measure the capacity of the battery. No worries. let it charge from 0 to 100% and check how many mWh went into it. You can also check the QC rates and voltages on the D+ and D- lines or how good or bad cables are.

It would be a mess explain to the bank why I don't want anymore that loan I've already signed
"You know, my car doesn't work with AA, so here's you thousands euros back" :laugh:

That's also my favourite so far, for the better and faster CPU, but I don't want to pay 100 euros more than the Mi 9T only for that.
I'll keep an eye at discounts on GearBest and Banggood.

That's cool stuff!
I'll definitively buy one in my next AliExpress or GearBest order, maybe when I'll buy the phone

Hi @lukesan, hi all,
here I am again. I can confirm it was an hardware issue. The USB connector in my Xiaomi Mi 6 was faulty.
I've eventually bought a new Xiaomi Mi 9T (regular, not Pro) and it's working fine.
It has been immediately detected the first time I connected it, without any particular configuration and with the same cable I was using before.
I'm just having a minor, but annoying, issue: Android Auto randomly disconnects itself during the drive.
Sometimes it doesn't disconnect at all, more often it disconnects one or two times in a 30 minutes ride and seldom it disconnects every 5 minutes.
I've already uninstalled and re-installed Android Auto on my phone, I've given all possible permissions to it, including Auto Start, and I've disable MIUI battery optimization.
I'm using Android Auto 4.9.594934 on MIUI Global 11.0.3.
Any ideas on this issue?
I'm using a brand new short cable (10 cm) from MYLBOO (USB Type C Cable 5A,USB C Cable 5A,MYLBOO High Speed Charging & Data Transfer USB 3.0 Type C Charging Cable for Samsung Galaxy S9 S8 Note 8, LG, Huawei，Sony,and others USB Type-C supported devi (0.1m) - https://www.amazon.com/dp/B07KZZW155/) but since today I'm trying with the original Xiaomi recharge cable, which is uncomfortable because it's too long and doesn't fit the phone box of my car.
I've already done some researches and I see people is solving similar issues with Anker Powerline+ cables (like this Anker Powerline+ USB C to USB A Fast Charging Cable, for Samsung Galaxy Note 8 / S8 / S8+ / S9 /S10, Sony XZ, LG V20 / G5 / G6, Xiaomi 5 and More (3ft) - https://www.amazon.com/dp/B071G5WSK2), so in case I'll try one of those, but they're also too long for my car.
They're talking about that in this thread: https://support.google.com/androidauto/thread/13722361
I've also found this Android Auto FAQ which could be useful for anyone who's reading: [FAQ] Can’t connect or stay connected - How to diagnose/address the issue - https://support.google.com/androidauto/thread/2467281
I'll try to come back here to write how this ends, too.
Thank you again for your help, lukesan!

No worries man, glad you finally have AA in the car. Sure that Mi9 T is more than fast enough!
I had the same issues and it is both annoying as it is dangerous. Probably it's the cable. (lol check the reviews on your link)
I have some sh*t cables that (seemingly, you guess what I recommended to measure the current) that charge ok but still slower than other good cables and disconnect randomly in the car. Coincidentally the 2 cables that I know for a fact that I have issues with are braided cables (you know the ones with the cloth around them). They were cheap and there is no brand name on them.
The cables I now use everywhere are from Orico or Ugreen which you can buy for really cheap on Aliexpress (but have to wait for a couple of weeks, hint: check shipping options and for 1 or 2 euro more take the registered or alie standard one). I always buy spare cables in all length variations and I tend to have spares at my work and in the car.
I even have a 3 meter long cable which still charges full speed and is ideal when I travel and stay in hotels. Check the reviews and variation of cables. (saw a 25cm Ugreen one while doing a quick look)
That Anker is also a very good brand but unfortunately for you a bit on the long side for use in the car. Btw : Their chargers are also very good

Hi @lukesan, hi mate,
I've ended up buying a short UGreen 90 degrees cable, as you suggested, and it's working great!
It's this one, 50 cm (1.5 ft): UGREEN USB C Right Angle Cable 90 Degree Type C Fast Charger Compatible for Samsung Galaxy S10 S10E S9 S8 Plus Note 9 8, LG G8 G7 V20 V40 V30 G6 G5, Nintendo Switch, GoPro Hero 7 8 5 6 (1.5ft) - https://www.amazon.com/dp/B07PFHB3R4/
The only issue is that the 90 degree angle is in the wrong direction and the cable gets pressed against the border of my phone box, so I don't think it will last as long as it would have (but that's my usual luck):
I'll probably buy a couple of spares of the same cable.
A friend of mine also suggested me this cheap cable he's using on his Kia Stonic: 4A Reload 25CM USB 3.1 Type-C Quick Sync Cable for Game OnePlus 6T / 5T - Red 25cm - https://it.gearbest.com/chargers-ca...=1433363&_branch_match_id=743761025176719207#
I'll probably buy a couple of them too, since they can be oriented in both directions.
So, I think I've solved all my AA issues!
Thank you very much again for your help!
