Laptop won't detect phone being plugged in - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

I had previously setup my MI account and done the oem unlocking and everything got the wait screen for 168 hours, now I'm trying to get back to that screen but the flash tool won't detect the phone being plugged in. I can no longer access android USB debugging either, whenever phone is plugged in it just charges the phone and whenever I change the USB config in settings to midi or file transfer it does nothing.
Really want to unlock and start flashing new Roms, should I do a factory reset or what can be done?
After setting up my MI account, I accidentally updated to the latest global rom, as an update was available, I'm scared it may have affected the device permissions.
Any help would be much appreciated if anyone encountered this issue!

reboot your device to fastboot (power + vol down) and plug yout phone on your pc... nothing happens?

Nope nothing happens idk if it's phone cable or laptop yet, I'll try more cables soon and get back, but I've never accounted a problem like this before

You really have to try in another PC, with another cable... It's a hardware fault for sure...

I got it to work with another laptop but upon rebooting to fastboot it couldn't detect the phone anymore, same wire so I'm confused

It could be the USB cable.
Are you using the USB cable that came with the phone and is it in good condition?
Try and get a good quality data USB cable

I was using a third party cable, I'll wait the standard one week wait time before attempting to try to unlock it as it's pointless without waiting the specified time
Also, I just came to realize this but since Xiaomi doesn't sell in North America, I imported the phone from Hong Kong, and in the packaging it was intended for EU Markets. As such I'm running MIUI 10.3.3.0 (PFKEUXM), which I believe is the EEA version and not the Global Rom version, even though the settings say otherwise, could the fact that I'm located in Canada and trying to activate from here affect my chances of unlocking the phone in any way?

[Q] USB connection not recognized

Hi all,
I have problem with connecting my O2X to laptop.
When I connect phone to laptop phone start to charge, but USB connection is not recognized and no notification on phone (top left corner) is shown.
It was working once, but since then my phone was updated via OTA to V10e and then to V10f yesterday.
My phone is on stock.
I've seen on other forum that people had similar problem but I didn't found any solution.
I've tried different USB cables, different laptop (home and business - on both was working once before), unnistaling drivers and similar.
Please help!!!
Thank You.
I have the same problem and I still don't understand if it is hardware or software related.
In my case the usb sometimes stop working for a certain time, sometime a couple of hour, some time for a full day. After that magically start to work again.
I've tried every in my knowledge but without success.
You are not alone

Using Topogigi 1.6 this exact thing hit me yesterday, I suddenly lost ADB-access (I was programming at the time, and suddenly couldn't upload the app to the phone anymore.) The "bug" top left had vanished, and no toggling of USB-debugging would turn it on again. I tried restoring froyo backups, tried wipe-install, didn't work. What finally solved it was to smartflash back to 10D. Very strange, I cannot find any logical reason for this behaviour, so it can only speculate it must be something illogical, like maybe overheating (wasn't overclocked.)
EDIT: Let me elaborate. When this happened I of course tried another cable, and what was extra weird was that it wouldn't even recognize a USB-connection, but it would charge. Plugging it back in the dock I normally use when programming would show a USB-connection, but no ADB. At first I was worried that perhaps the dock had pushed the pins in the socket too far in for the regular cable to get a connection. After smartflashing back to 10D though, both the dock and cable work as usual. So maybe, just maybe, a hot phone will expand certain areas around the usb-connection points either in the socket or on the motherboard. Again, just speculation. The usb-connection has worked fine since, using any cable.
Happened to me as well. In one day i can't connect my phone to the pc but after two weeks when i connected the o2x to a pc with vista the problem was vanished. I connected to my usual pc and the same it worked. let's hope that i will not have anymore this problem. It is possibility that your phone will revive i one day. good luck.
I think I may have solved this particular mystery, I'm now able to reproduce it at will, and get usb/adb functionality back.
It happens through a combination of ADB crashes/bugs on a computer and a usb-stack crash/error on the phone.
I can reproduce it by plugging in another phone/tablet on the computer (while still having the phone connected), installing/running something from eclipse on the other device, unplug and replug the o2x and then try to run/install something on it via ADB. This invariably leads to the ADB-icon (the status-bar bug-icon) disappearing, *and* it will lead to the phones USB not working on another computer, or even another port on the same computer.
Funny thing is, if I reboot the phone, and plug it back on the same computer, this instantly leads to the same behaviour. USB will only get recognized on the same port it was plugged in the last time, and ADB will still not get activated. Trying to connect to another computer *after* this will not work.
The solution is simply to reboot *both* the phone *and* the computer (or just kill adb I guess) before plugging in anything.
Plugging in the phone while *either* the PC *or* the phone is in this confused state will lead to both devices malfunctioning in the same way as before, which is why you cannot simply connect the phone to another PC. (Although unplugging the phone, rebooting it *before* plugging in to another computer should work.)
Thank You for info.
I just tried it but unfortunately it didn't work for me. I've tried restarting phone couple of times, plugin into different computers but phone still doesn't recognize usb connection (just charging).
I this the problem is in the phone and it maybe due to update to v10e and v10f.

Hm, okay, your problem may be of a different kind. I'm not entirely convinced yet, as you don't mention having rebooted any computer. So just to satisify my curiosity, do exactly these steps in the following order:
1) Unplug the phone from the computer.
2) Power down the computer
3) Power off the phone
4) Turn on your computer
5) Re-install the LG USB drivers
6) Turn on your phone
7) Connect the phone
If this doesn't work then you indeed have a completely different problem, and we're back to speculating.

Trym,
Does that mean you were able to smartflash despite having USB connectivity problems? I had these problems with my first O2X and after I flashed MCR I couldn't connect to USB at all. Luckily this was within the exchange period and I was given a replacement handset which hasn't had these issues but then I am still using stock 2.2
I did try all combinations of reboots on the phone and also driver installs etc on the problematic handset but nothing worked then.

That's exactly what it means, yes. It's never been a hardware problem (luckily)

You may of course have had a genuine hardware fault, after all usb-sockets are among the first things to break on any phone. I thought my phone was a goner as well, until I discovered the things mentioned in my post. It's a really sneaky affair, it would be impossible not to assume the phone is broken the first time you experience it.
EDIT: Removed invalid assumption.
Just to report that I've tried everything, including connecting phone to computer on which my friend runs Nexus S with no problem and then connecting to computer on which my phone was never connected.
Is there easy way to revert to v10d (last version I know my usb connection worked)?
I don't want to experiment too much because this is my business phone.
Maybe I'll just wait for GB and V20e (I hope it will finally be released soon) and hope that this will resolve my problem, but until them I'm missing one of main functionality
What a waist, since I get the phone with all that fuzz about it, is nothing but problem after another: rebooting, battery drain, wifi problem, usb connection... whats next?

Assuming your usb isn't actually broken, yes, it's pretty easy. Download 10D from here: http://forum.xda-developers.com/showthread.php?t=1035041

NOTE: The instructions are for flashing baseband only. In addition to that, you also need to select the .bin file in "Ap bin"

Weird. Glad you got it working.
Looking around on different LG Forums, as useless as they are, the support-people always gives the advice that you should take out the battery, and leave it out for five minues to "clear residual memory." (This, apparently, is the solution for any kind of problem with the phone ;-)) That's always sounded completely nuts to me, but that's the advice I'm going to give the next guy with usb problems ;-)
And another one bytes the dust.
That's ultra weird. one minute everything is just fine and on the other, USB is dead.
So, apart from the procedure TrymHansen gave us a few post back, there is no known solution/diagnose/whatever for this problem, right?
SmartFlash will not detect phone...
My post from other thread which was closed:
My optimus 2x is not detected when I plug it to my laptop via USB.
Turn on mass storage" in the phone does not appear, it's like I'm just plugging in into a wall charger.
It could connect just a few days before, same laptop, same drivers (LG mobile united drivers)
Have tried it with 3 different laptops, still can't connect (drivers are installed)
A google search reveals other people having the problem as well and unable to solve it.
Can't return it yet for warranty because superuser app is still there.
Originally, I rooted it using superoneclick. Can't unroot it in superoneclick since not detected in USB.
So i unrooted it using z4root (without a pc). It's now unrooted, however superuser app is still in the app drawer.
i believe mine can be detected from smartflash so maybe i can flash stock rom. will doing this remove superuser.apk?

So did you try to flash a stock rom and did solved your usb problem ?
I will try with a modaco rom next we.
lol, is this fixed or not?
ive had the same problem.. when my rom is totally chrashed, and usb is like stuck?
strange is, all the other usb devices (wifi dongle, not keybord mouse) stops working when i plug in my phone? also the phone does not see that there is an data cable in him so i cant mount my storage?
is this an warranty issue?

[Q] Broken screen trying to recover data

Hi,
I broke the screen of my samsung note a while back. The glass is okay, it is the inner screen which is showing a little crack when looked at from an angle. The day it broke i was able to see the screen but after 1 day the screen has become completely black. I am not in my home country and hence can not get the screen repaired, and need some of the files from phone really badly. The trouble is I can not unlock the phone, as i am not sure of what is happening on screen.
I tried to recover data but the phone is locked. If i can either turn on the wifi or 3G of my device by some way ( then I can excess the samsungdive application and unlock my phone) or if I can bypass the pattern somehow or can enter it via pc ( like in know there exist some screen monitoring applications for android 2.0 and below) i can enter inside the phone. I have been trying a lot of stuff and I dnt want to blindly reset my phone ( i think if i reset it I should be able to unlock it). Is there any other option anyone can suggest me.
Thanks in advance.

wasnt your data (2G or 3G) already on? if the data was already on and if you restart the computer it still remains on, moreover there is no harm in trying to unlock from samsungdive. i have lot of ideas coming to my mind but dont know if they would make any sense or may be there is a simple way to do it but i cant think of it.

Nexus 6 no longer recognising PC (and PC no longer recognising phone) in Fastboot etc

Around February, my phone was working fine and connecting to my PC and being recognised (in both the phone AND PC/Device Manager). Because I was rooted, I used Wug's toolkit to flash the latest factory image at the time (which included the February security update) and kept data as I've done in the past. It was fine for ~2 weeks after that factory image flash and then my phone just stopped recognising the PC, and my PC stopped recognising the phone as a device. It was completely out of the blue, and seems unfixable.
When I plug my phone into my Desktop - it just charges. It doesn't appear in the device manager at all (image below - Device manager WITH phone plugged in and not appearing):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
I've had to do the old 'update drivers' thing in the past with other phones, but they would normally appear under "Phone" or "Other devices" - but both are missing from the list ("Show hidden devices" used in that image). There's also no yellow triangle to say an unknown device has been connected. It just flat out doesn't know it's there. I've also updated/re-downloaded the SDK (and Google drivers) but the phone still isn't recognised.
It got so bad, I had to use USBDeview to uninstall the drivers in the first place because they never appeared. It still didn't help.
On the phone side of things - I'm not given an option to mount the phone as any form of storage. It just behaves like I've plugged it into a charger.
In the USB and Storage settings (image below) - I'm not given an option for ANY form of USB connection.
And in the notification shade (again, while plugged into my PC) no option is given. It just charges:
I've also tried factory resetting the phone, since it charges fine so I don't think it's the charging port but now I've lost root AND the problem is still there. I still can't install OTA updates because in order to get Root, I had to use a kernel which disabled those "this device has been modified" alerts when you boot it, which means the OTA just fails (Error 7 (or 6) - and something about recovery).
In Fastboot, it just says it's 'charging' and makes no attempt to connect via USB. Recovery is the same so it doesn't sound like an Android problem per-se since it affects Fastboot but hardware wise - would could it be?
As a last resort, I've also tried multiple cables (working one for the Nexus 7, DS4 one and a Motorola one) and none of them seem to have helped.
I've also tried different USB ports and on different machines - both running windows 10 and both with the drivers installed but still no luck.
Any help would be greatly appreciated because I'm just sick of this problem at this point.

My idea is to try to connect to another PC, when possible not Windows 10.
This to check that the problem isn't caused by the phone.

If changing PCs doesn't help, try a different cable. If that still doesn't work, you likely have a problem with the micro USB port.

Tried 3 different USB cables and no luck.
I've got a spare microUSB I bought from eBay which I'll need to solder but the only thing I could find on faulty ports were that it doesn't charge right but mine does.
Going to try connecting it to a windows 7 laptop and see where that goes. If it still doesn't work - the only thing left would be the port itself which will be a pain to replace (and still doesn't guarantee it'll be fixed).
Honestly it sounds like a hardware issue with the MicroUSB port. I can confirm it works fine under my Windows 10 PC at home, both normal access for files and I've also had no issues with using fastboot or ADB. If it's under warranty try to RMA it. If it's out of warranty see how much it would cost to change the MicroUSB port from a local shop or try it yourself
I've had the same thing happen to me twice. I think that some times Windows updates and kills the drivers. Whenever it's happened to me I've installed a universal adb driver that's floating around XDA. Once that alone fixed the issue. Once it didn't. The time it didn't I had to open every device heading in the device manager until I found one that had Google hidden inside it. I uninstalled the Google driver from there in the device manager and then plugged my phone in. Windows did the normal device install from the phone and all was fixed. Hope that helps. Good luck. Windows 10 truly sucks.
Maybe to rule out pc, find a buddy with android phone and see whether you can detect it with adb or fastboot on your pc. I think those drivers are supposed to be universal (all phones)....aren't they?

Tried it on my Windows 10 laptop as well and it's the same problem. Just tried it on my older Windows 7 laptop as well, and same story.
My older Nexus 7 2012 connects fine to all 3 so I don't think it's the drivers.

Sadly already tried this but what's worse is - I've looked through all the possible 'dropdown' options and the drivers/device doesn't appear but it appears in USB Deview (where I uninstalled them).
Tried both the universal ADB driver and Google's own one from the SDK - sadly didn't work in the end.

I'm beginning to think the same to be honest. It doesn't connect in Fastboot, which leads me to believe it's more hardware than software because if it were Android itself screwing up - it would at least work in Fastboot as that doesn't touch Android.
It doesn't mount as anything, so I can't access my files on any of the systems I've tried. I've even tried my younger brother's laptop and it doesn't 'see' it (but his Nexus 4 connects and works just fine).
I bought my Nexus 6 ~6 months after release so it's out of warranty (what a time for it to run out of warranty). I bought a new USB port from eBay ages back so I might have to fit it myself since all the repair shops I've contacted would take ~3 days to do it and I need to have a phone.
I really hope replacing the port will fix it. It charges fine, which makes me slightly worried it won't work (as it's not an obvious port issue) but I can't think of anything else which could be the problem.
Thanks to everyone who's replied though! I'll see how the USB replacement works out.
Hello all, long time lurker 1st time poster....
I've never really felt the need to post because i normally just do a search and work things out for myself, but i'm now having the same problem and noticed this around 2-3 weeks ago after trying to copy some pictures i'd taken onto my Laptop from my Nexus 6 and it not being recognised, only charging.
I've tried EVERYTHING (apart from reverting back to Windows 7) mentioned in this thread and in a couple of the other threads i've found where a few Nexus 6 users have had the same problem. I'm now stumped for ideas.
My Nexus 6 runs as flawlessly as usual, no battery drainage, stutters etc.
I'm currently running Temasek's 18.2 (5.1.1) rom, and have been using it now for a long time (probably for 8 months or so with absolutely no problems whatsoever). I've updated to MM a few times and tried a few different Roms, but to be honest i just found that LP worked better for me so have always just reverted back to the last official LP 5.1.1 LVY48I Rom using Wugfresh's Tool Kit (i know i know , but having rooted/played about with other Samsung/HTC Phones in the past, i just preferred to use it) and then restoring my backed up reliable Temasek's 18.2 Rom.
So, what else can i say....well, i called Motorola around a week ago for some advice, just incase there is a potential warranty claim (because my Nexus 6 is only around 9 months old), but as i have a Custom Rom on it, they said that there is nothing that they can do.
I do have an official clean 5.1.1 Rom LMY48M that i fortunately backed up to my TWRP Folder on my laptop just after installing TWRP+rooting. I did 1st of all also try connecting my Sandisk Ultra Dual USB DRIVE 3.0 to my Nexus with the Rom on there, but the Nexus just doesn't even know that the USB Drive is connected, so I have had to send it via bluetooth to my Nexus from my laptop, as that was the only way to get it on there. I found that Zipping the file 1st, sending it to my Nexus via Bluetooth and then extracting it once i'd received it saved hours in time because the file was too large in its original form (something like 4+gb down to 1.9gb). I've also tried a few other LP Rom's in the last couple of weeks, hoping that maybe i'd accidentally switched a setting off or something and that the phone would correct itself and my connection problem would correct itself but i've had no joy.
NOW...........................probably a silly question but it's the only other way i can think of returning to Stock for a potential warranty claim. I know that i can install the official 5.1.1 Rom i backed up via TWRP because i've tried, but is there a way to remove Root+TWRP and return to Stock Recovery+remove root without using a PC ? I'm pretty sure that there isn't but feel the time is right for me to ask the Question as i'm really not 100% sure.
Many Thanks in advance for helpful advice given, like i've said at the start of this post, i've held off asking Questions before because i had no real need and just searched :angel: , but this has really stumped me .
CHEERS
Some quick thoughts.
1. The Motorola rep you spoke to I think read from a script and didn't realize you were talking about the Nexus 6. As this is a developer device, having custom software on it should make no difference for warranty purposes. If I am mistaken however, read on.
2. If you're going to install a stock ROM on the Nexus 6, a PC will be required, especially if needing to replace TWRP with the stock recovery. So why not download the latest Android 6.0.1 image from Google's Nexus firmware page and flash that? There's no point in reverting to an Android 5.x image simply for a warranty claim.
Many thanks Strephon Alkhalikoi for your quick reply and sorry for my slow 1 (work was getting in the way....)
1 - at some point today, i hope to chase my potential problem up with Motorola or possibly Expansys because i purchased the Nexus 6 from them via Play.com/Rakuten.co.uk
2 - The 5.1.1 Stock image that was going to be put on the Nexus was only a normal TWRP back up i'd saved by chance straight after flashing+rooting that i had saved to my Laptop. There is no way for me to flash any new Stock software because my Nexus is just not recognised by my Laptop. I've tried installing+uninstalling drivers/Minimal ADB Fastboot file/Wugfresh's Toolkit, plus Developer options usb debugging on/off etc and Settings/Storage/USB Connection (3 little dots top right) which gives me 2 options Media Device (MTP) + Camera (PTP) but after changing either, still no sign of connection, just charging.
As it stands it works fine on 5.1.1, but with me not being able to Flash any Stock Roms because of my Laptop connection issue, it will be forever more on LP. I could put up with that but obviously i need to try and sort this out also because i can't transfer normally any media files backwards/forwards (only via the much slower Bluetooth) and it will affect any future sell on value when it's time to move on.
Many Thanks once again
**Latest Update** for those not asleep yet....
i spent nearly 20 minutes on the phone around an hour or so ago explaining my problem to Motorola. It's not something they've heard of before so couldn't really help and that by being Rooted, their repair center will not touch it. I can only think that if i'd purchased the Nexus 6 straight from Google, it would not have been such a problem to handle a Rooted device so it would have been taken in for repair i'm guessing.
It was explained to me that i would be contacted via email once a technician had been consulted and here is the reply i received a little while ago.
"Thank you for contacting Motorola.
As promised, I have spoken to a technician who has a couple of suggestions.
A. As we discussed, he also suggested connecting your phone to another computer.
B. Be sure that you have Windows Media Player and the PS Drivers installed on your laptop.
[link removed due to my lack of XDA posts]
C.
At this point, I would like to suggest that you restart your phone on Safe Mode.
Safe Mode puts a phone in a diagnostic state and it can help us determine if a third-party app is causing the device to malfunction (freeze/reboot/run slow/error message). Safe Mode temporarily disables all applications that have been installed via the Google Play store. Performing this troubleshooting step is necessary to determine whether a third-party app is the cause of the issue you are experiencing.
Please long press the power button > long tap on power off > reboot to safe mode >ok.
If you find that the issue is resolved in Safe Mode, please delete all apps from the phone, and gradually add them back one or two at a time, until you are able to identify which is causing the sound issue.
To move phone from Safe Mode back to normal mode, you can simply restart it.
D.
To be sure if the problem is software or the port itself:
1. Reboot phone in Fastboot Mode
2. Plus phone into computer
3. If phone is recognised as 'Fastboot Shamu NS,' the issue is software, rather than a physical issue.
In this case, you would need to reset the phone, which I know you are hesitant to do, but you should then be able to reflash the factory images, available on the Google website.
Unfortunately, there little else that we are able to do to help you since, as discussed over the phone, SBE UK, our repair, centre will not accept a rooted device.
For any further assistance or information please do not hesitate to contact us, quoting your Customer Reference number. We are reachable on 03339 997 550 to discuss the matter further with one of our experienced customer service agents. Please contact us any time between the hours of 8am and 8pm from Monday to Friday.
Kind regards,
Anna

I've tried all of the above (apart from connecting to another PC) and still no joy so it looks like i'm stuck on LP. Like i've said before, it still works as normal so no real hardship apart from the lack of Software updates and the normal easier transferring of media files. I'll keep an eye out on this and the other threads to see if a solution becomes available.
*I've posted the above it as it might help someone else out in the future*

SBE repaired my nexus 5, when it was rooted/unlocked.
Is there any damage to the usb port? Never tell the customer service rep that your device.
Cheers for the reply JonesL
As far as I'm aware, there isn't any damage to the USB Port. I did say I thought that that might be the problem but she said if it was the reason, then the phone wouldn't charge at all.
I could still send it in and hope that on the off chance they don't check for Root, but i will be liable for the postal returns plus the hassle of being without a mobile whilst it is away. Also, I've now given my IMEI number and a couple of other details so I'm sure I'll now flag up on their system when its checked.
Oh well....

[Q] Unable to recognize phone when hooked up to computers

Hey folks,
So I have a completely unmodified, stock Canadian N920W8 on 6.0.1, and no matter what I do, I cant get it to be recognized by Odin on my Win10 or Heimdall on my Mac.
I've done everything I could think of. Different cables, different ports, even different computers. Reinstalled the USB drivers, everything.
Anyone have any ideas? My phone won't fast charge, and is lagging more and more. I can't even Odin back to stock because it won't recognize. Factory Reset just cleaned out everything but nothing has changed. OEM unlock and USB debugging on, it won't be seen by the computers.
Any help? It's past manufacturer warranty, but it's still a good phone and I don't wanna lose it.

Did you install the actual drivers or just the ones that Windows installs? I use the ones that Samsung smart switch installs and I have no issues. If it is not fast charging and your computer does not recognize the phone it may not matter what drivers you use.
I used the Samsung USB drivers for Mobile Phones from Canadian support page. And that's on a fairly fresh win 10 install, too.

If you can I would suggest installing smart switch and see if smart switch sees your phone.

I tried it on the Mac, smart switch didn't see the phone booted up. Didn't get a chance to try it in Odin mode. I'll try that tonight. And also on the PC. Any other suggestions?

Unfortunately not. I was hoping smart switch would see it. I would not rule out a damaged USB port.
I hope not... this is way past warranty, and I wanted to flash the thing with Khongloi's new Nougat rom... if it won't be recognized, then I can't even back it up or re-flash it to stock. Which is not a good thing...
No other suggestions, @CodeNameRedNeck ? You've been a huge help otherwise.

Just to be sure. Can you transfer files from your PC to your phone and vice versa? Do you have any USB 3.0 ports? My phone seems to work better on 3.0 but still works on other types. Do you still have the Samsung cable? I know you said you have tried other cables but I used to have two cables that would not do data.
I tried with a brand new from the box cable, into four different usb 2 ports on the Mac and 2 usb 3 ports on the windows 10 PC.
No luck with it even being recognized for file transfers either.
@ve6ay, I could be wrong but I would say you probably need a new port. You should be able to pick one up relatively cheap. Good luck.
That's my thought, too, and in that case, I'll forgo anything. The contract is up in October, and it got the OTA update to 7.0, so I'm okay with it for now. I'm not into opening up her phone (which hasn't even been rooted yet) to switch out a port that I'm not confident enough to switch out.

Did you try going into Developer Options and then scrolling down until you see "USB Configuration" and setting it to MTP? Or open the dialing pad and enter *#0808# and then making sure it's set to MTP, ADB and then try again.. If that doesn't work then it really is your port connection and it's actually super easy to replace and cheap too! All you'd have to do is heat the back up so you can loosen the glue up and then slowly pry the back off and then remove like 16 screws(lol) and then at the bottom you just unscrew it and easily pull the thin connection out.. I've done it several times so far although trying not to break the back glass is super hard..
The back glass got shattered in a drop last summer. So that will probably be a problem. Like I said, new phone this fall, most likely the next Note series. Though I'm tempted to go with an Exynos variant from across the ocean.

Everything is right until there
Do your pc recognize the phone in fastboot?
If not, u need to download driver https://forum.xda-developers.com/t/...vers-15-seconds-adb-installer-v1-4-3.2588979/
Maybe u should change the usb port/cable
For more info
https://c.mi.com/thread-2262302-1-0.html
thanks guy, downloadeed the driver all loaded but i had downloaded earlier a xiomi dirveer and installed so the last portion of the adb install bonked cuz i think it found another driver already installed, nevetheless
usb debugging is on, oem unlockiking is on, i connec the phone to the unlock app via qr, because via log in i get an error at checking for security bla bla, , so when logging via qr i get a message on phone logged in,
but the unlock app keeps telling me that i am not connected to pc, also
on phone ,,,, just a FASTBOOT , faded letter
on pc not connected and unlock greyed out
any other option on dev besided usb and oem, i am logged in in mi acct.
the phone is on miui 13.0.
also i inserted a 256 gb micro sd which cost me an eye, and this thing doesn't see it , there are no options in setting/storage for se or anything it works fine on my huawei p30 and p40
thanks guys for the patience very very much appreciated,, on all the videos i've seen the fastboot shows with a letter a and a rabbit,,, i only have thee word fastboot,
I hope the memory card is not for this phone? The mi11 Ultra does not have a memory card slot. If yours has, then I'm afraid it is not a real Xiaomi mi11Ultra.

As your info you provided, the problem come from only your PC, maybe your window's driver.
Do u run Intel or amd system?
i've downloaded a bunch of driver a few mi suites, nothing connects it to pc,
the best was a mi suite message, i need to update device, whatever that means.
at best i get something called MTP in my safe to remove usb icon in taskbar
yet nothing in win explorer, nothing in dev mger, no errors in dev mgerr usb area
removed bunch of usb rescanned nope no changes.
i guess this fone is not locked its cemented. i can use google and all , but no pc connection
wrote to giztop, maybe you guys can pressure them , its not a hole in the wall thing , they're good but i think they screwed up here and hope we can make a case to return and allow me to buy the global, a fone that does not connect to a pc is just useless, no not really but clise enough
any ideas,,,, acer predator g9 791 intel i7 old ggen , win 11 dev. latest 22759

Still lot of problem with win11
I dont think its your phone problem, it about your pc
I've seen a replica of the Mi 11 ultra, with an imitation of a second display on the back. The smartphone is very cheap ($150 ... 200) and not well made, but one can be deceived if one has not seen a real Mi 11 ultra. I hope this is not your case!

he already post the link he bought it
and as it has official miui13 and everything else i can say his phone is real Mi 11 U
I just couldn't understand that he bought a SD card and when inserted, the phone couldn't see it. No card slot on an official but I have seen copies with a card slot.
