i did it first.
I think the problem is somewhere else.
The computer also has a problem with detecting the device. Only after a reset the phone start detecting.
i think it's a hardware problem.
our 9t was also for repairs (display error) and the mainboard was replaced there.
if the problem with miui is there, i would hire xiaomi support. my repair was quick and uncomplicated!

I'm wanting to restore a factory image but can't get the phone to go into anything but boot-loop.
Before I replaced the broken screen the phone booted fine.
Trying this, but won't work.
Press and hold Volume Down, and then press and hold Power simultaneously until the device turns on.*You will see the word Start with an arrow drawn around it.

for boot loop - check proximity sensor / headphones module connector for properly connection to mainboard .

I have a problem with my Android car audio device.
It has a bootloop, I tried to boot recover but menu only shows "boot system now" and "apply update from adb". In the "now send the package you want to apply..." screen I tried to connect it whit an usb A-A cable but PC does not detect it (windows and ubuntu) Also adb via wifi not working. To get in this bootloader I grounded the RESET PWR COL0 and COL1 testpoints on the PCB. I also soldered wiring to TX-RX TX0-RX0 TX1-RX1 and GND and connect to PL2303 usb stick but nothing happens with tools like miraclebox or SP flashtool. I thought I was lucky to have one similair headunit to get the stock firmware from but I cannot get into it... Also tried to figure out if the USB_ID pin is grounded but I cannot find it on the PCB since almost nothing is labeled. Is there a way to get the USB in device-mode?
Some info can be found when websearch specdevice mcx-1705ad
Thanks for help!

I guess you need drivers for your computer to make it recognize the radio?

In windows, yes. I installed the vcom drivers. In ubuntu it should work without.
Please help me
recovery options missing
I tried many options to boot into recovery but the only recoveryscreen shows me this 2 options;
From the seller I have the "update.zip" file and tried via sdcard and usb stick but I don't know how to recover. ABD also not working because only have USB-Host ports... Am I out of options now?
Really nobody, I'm sure the knowledge must be on this forum!
hello. did you manage to solve this problem?

Disconnected while flashing QFIL? Nothing on screen, device vibrates and led flashes every 10-12 secs?
I have easiest method for you and no need DEEP FLASH CABLE. All you need is Aluminium foil paper and TYPE-C USB Cable.
Before start make sure you installed all drivers and QFIL on your PC.

Hi,
I changed the battery and now mi Mi9T doesn't want to switch on !
Just vibration, and I post you the screenshot of the device manager when I plug it.
The USB debug was authorized, and the phone is rooted, if it can be used.
Thanks a lot, I really wouldn't lose my data !

I forgot : I made cross tests with another Mi9T, motherboards have been changed, and my screen and battery are ok with the other motherboard.
Then the problem is on my motherboard.
Nobody knows ?
You probably damaged motherboard during change or shorted it. It's not possbile to tell what you did exactly through forum
So, I changed the motherboard by new, 3 switches on ok, then same problem at final remounting : vibration and black screen !
Then 2 options I think :
- I make a shorting at remount, but I don't know how, and I broke the 2 motherboards
- Something happens and put the phone in alternative mode, and I don't know how and how exit
Or your screen flex has bend pin. Check for damage at connections
I have already replaced the screen flex cable, it fixes nothing unfortunatly.
I tried with usb-c hub and a hdmi link to the tv, the hub activity light is on but no signal on tv.
It means the phone switch on correctly but the video signal can't run to the phone screen or the tv screen.
Change motherboard, it looks like something is damaged that controls screen. It will be hard to diagnose
Aliexpress accepted the motherboard almost full refund without return.
I'd want to re-order a new one, but the same issue could be happen and I can't know when and how !!
Any fix? battery works on another unit
The device seems to be able to enter download mode briefly, but then reboot into LG logo and boot loops there.
Entering recovery just bootloop as well.
It's dirtysanta rooted.

The only thing I can think of is the contacts on the phone that connect to the battery are dirty. Not making a good connection with the battery. Maybe try and take a Q-tip with some rubbing alcohol and clean the contacts on the phone. Let it dry and put the battery back in.

I cant think of anything else sorry. Might be a hardware issue with the phone.
Just an update I sent it back to the seller and he fixed it for a small fee
