Cannot connect to PC via USB cable - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hi there!
Since the latest bigger Windows 10 update (4-5 weeks ago) Win does not recognise my phone. I can charge it, but there is no data connection between the two. I always use the latest Xiaomi.EU ROM and I can only blame the Windows for this. There no TING sound upon connection and I do not see my phone in My Computer. I tried to (re)install drivers, but does not happen to work after several updates (different versions). It really annoys me, because it's hard to transfor big or many smaller files over WiFi, but anyways I think we can all agree on the importance of cable connection.
I tried two different cables and 4 different USB slots on PC.
Does someone have the working drivers for me?
Thanks!

I dont see my phone on my pc either but i do have a connection, as in i am able to push files to my phone with adb commands. Also i do get a ting sound when connecting but i just don't see my phone on my pc. Like 2 weeks or so ago i could see my phone on my pc but not anymore so maybe you're right about it being the windows update.

Thank you for your input. I found this topic and his software helped me. I deleted every previous ADB softwares and drivers, installed his and my phone now is showing in My Computer!

Cant connect hd2 to computer!!

this is my problem,
when i connect my hd2 it charges but the computer doesn't recognize it. on the phone settings it is set to active sync. i also have 2 computers; xp and vista, both do the same thing.
i could careless about active sync, i just want to plug my phone into my pc and transfer files in and out. ive also tried the disk drive option but still no go?
if i enter bootloader and plug it in it recognizes the usb setting but when the phone is normal, it doesn't??
it did this with the stock rom and its also doing this with nrg titanium rom.
any help would be appreciated
Same thing here.
It charges through USB but it doesnt connect.
If i choose the storage option it works fine.
I want to sync my outlook and i cant...
What the heck...?
i know this may seem a bit "it helpdesk-ish" but try re-booting your PC
Come on... give something drastic!
Already done that, rebooted the pc and the hd2...
still nothing

believe it or not i have done that mannyy times and did alot of device manager things to try and let both computers recognize the hd2 but still nothing haha..
ive had previous hd2's and they've all connected fine untill this one, maybe its this specific one thats giving me trouble. but regardless, it charges via usb then it should be able to recognize it
Check the active sync settings to ensure that usb connections are enabled. You can tell be looking at the system tray icon - there's a read circle with a white X in it if USB is disabled.
Saying that though, if it doesn't even recognise it when the device is in USB mode, I'd try a different cable. It's perfectly reasonable that the cable could power the device but not fully facilitate a USB connection.

That is very weird. Sorry mate - never heard of it doing that for anyone before.
Make sure you have the mobility center/active sync program installed on your computer. Without it it won't work.
On Vista or Seven, with the HD2 plugged in, you can find the program/drivers by launching and refreshing manually Windows Update. On XP you have to do that manually.
Good luck.
This happens to me often. In my case I have found it to be a weird driver issue. Go to device manager and look for the yellow triangle. Right click and update driver software. This worked for me I hope it helps.
bit late but just flashed maxsence and i love the look, but have allready had to restart by phone 10 times in 10 minutes. I'll wait for the next release. back to GTX for now.
Good work NRG. keep it up.
this is one of the many WM6.5 errors!
need Android soon!
Ok here we go.
The phone did not connect through activesync to my pc. When i selected to connect as mass storage it connected.
I checked for driver issues in device manager but nothing came up.
I checked the hd2's activesync. Bingo! the activesync was crashing when i was running it. I had to hard reset the phone.
Now it works fine.
My guess is that maybe a program that i installed recently was buggy and created this particular problem. Unfortunately i have about 50+ programs installed (including themes etc) and i m not sure which one it was.
I was installing all the programs again today one by one and after the install process was completed i connected the hd2 to usb to find which app was the problematic one.
After installing almost(some were found useless) all of the apps (here is the crazy part) the hd2 still was connecting through activesync....
HTC will drive me nuts...
Anyway the phone now connects correctly.
I cant understand which was the problem....
as odd as it may sound i think i figured it out.
i think its the usb cable that im using, i have to wiggle it around for it to connect to active sync but once it connects its not a stable connection as it cuts in and out.
but charging capabilities work though!
pos wire, i ordered a new wire and if that one fails also, i will have to get my hd2 replaced for faulty usb port
thanks for all the replies much appreciated
@k20a1
Try to hard reset the phone.
It worked for me.
If not again, then use your warranty!

"Disk drive" mode not working with XP laptop
HD2 is working fine with my desktop, but wit laptop I can only use ActiveSync to browse files.
When I connect the USB cable I get:
"Found new hardware wizard"
but it tells me that it Cannot Install This Harware - Disk Drive
"An error occurred during the installation of the devie The system cannot find the file specified"
And I only have "Finish" to click - if I click it the wizard lunces again immediately and goes on and on with no end.
HD"/Leo does not appare in Disk Manager (I know ablut the drive lettering issue)
I'm sure its my XP issue, but I havent found drivers to fix that, and I'm not about to reinstall XP on my lappy in near future.

I share the same here and I was despaired of trying to solve it with any logical, as well with illogical, measures. Such as: rebooting, changing usb cables, reinstalling activesync 4.5, etc.....etc...blla..blla...blla...
However, I solved the "Transfer files issue" by taking out the sd card from the HD2 and connect it with an external cards reader to my pc.
The card reader connected and works with the same usb cable that does not work with the HD2.
That way I load it with all files and in the same occasion I reload into my computer the daily spb backup files.
However, I have the feeling that the reason for that problem is a missing file/driver named: "Setup1.SPL" in the pc windows operating system.
In order to solve that it seems that only reinstalling windows on my pc will be the solution which defiantly do not like.

[Q] Connect To PC mode not working

Hopefully this belongs in this forum, I do have a focus, so I assume so.
So when I cget into connect to PC mode and plug in the usb cord, it does not truly connect with the computer, meaning the red sign thing that means don't disconnect does not appear, the screen just shows the screen with an arrow pointing the usb to the computer.
Would this be a hardware issue?
I've tried my two usb cords on different ports on my laptop.
Any advice?
I've tried more or less every other fix, but there really is no fix online for this issue, can barely find anything.
Use the USB cable that came with the phone. Other ones do not work with the Focus.
Same problem, even when I'm using original cable.
Yeah, I've tried both of my cables, and nothing works.
Kind of nice to know that I'm not alone though. Heh
Same exact problem. Samsung Focus. Original cable that came with that very phone.
I can't get the frigging updates to install because when the phone reboots in Connect to PC mode, the system doesn't recognize that it's been reconnected.
And when I try to use the WP7 support tool, which ALSO requires the phone to be in Connect to PC mode, the computer doesn't know the phone exists.
This is for C2PC mode ONLY. Recognizes fine in normal mode, but update won't complete in normal mode.
same thing intially happened to me. But when in pc download mode you have to make sure that you give your pc 5 mins while connected to your phone. The pc will eventually recognize it! I freaked out too but I did wait for it and it connected. This applies to the windows phone recovery tool, which i ran, and the updates alike. I highly suggest running the recovery tool because I tried updating without it at first and i received the timeout error. Also, make sure you empty in settings histories in the following sections, ie mobile, maps, and search.
You guys and gals are going to LOVE this.
Nothing worked, and of course, my obedient ass was using only the cable that came with my Samsung Focus.
So on a hunch, I decide to borrow my wife's cable from her HTC Surround. The damn thing has "HTC" stamped right on it.
And it worked. PC recognized connection in the Connect to PC state, which it absolutely would not do with the Samsung Focus cable.
As to siralex241's comment, good advice: when you use the Windows Phone 7 Support Tool, after it checks System Requirements, it will say nothing -- not even that it's trying anything, and no hard drive activity -- for a long time. Then it succeeds in one second. The message I saw was that installing updates had taken over 450 seconds.

Solution for update error 800705B4
Same thing happened to me. Kept getting error code 800705B4. Followed steps here and it worked fine. http://support.microsoft.com/kb/2530409.
I'm on to the March 2011 update. Been creating the backup for a LONG time now.
Well to be specific I have been getting error 8018121C1 (Something close to that) and all the KB articles say is to use the microsoft fixit tool, but that never works. It mentions that its a problem with the driver installing, and I've read online that when in connect to PC mode, Zune times out the update because it is looking for the drivers for too long. Along with that, other people have said that the device isn't being recognized as the right device. I've checked and so far I've seen that it recognizes as Windows Mobile or Zune. I don't think any of those are the right formats to have the update go through smoothly.
I have given up on updating the phone as of now. That is, until I can find a working solution.
I don't think I should contact Microsoft or AT&T about it either, simply because I think that Microsoft will just give me the KB articles, and AT&T... welll.. its AT&T.
@ jayinatlanta I have yet to try connect to PC with a different cable though.

Computer not detecting phone through USB at all!

Argh, I am pulling my hair out trying to solve this! When I connect my phone through USB to my computer my phone detects the connection but my computer doesn't respond at all! I bought the phone used and it is already rooted but is using a pretty old rom and I wanted to upgrade it. It is currently running "Kernel version: 2.6.32.9 [email protected] #4".
Things I have tried:
Using different USB settings on the phone (Kies, mass storage, ask on connection)
USB debugging mode
Different USB cables
Different computers
Cleaning the micro usb port on the phone
Formatting SD card
wide data/factory reset
Nothing seems to accomplish anything, it still reacts in the same way.
Any help would be greatly appreciated!
The ROM shouldn't count.
First of all, has it ever worked? I just presume you're running on win7: did you installed the drivers as specified in several different tutorials on this forum?
What kind of connection are you trying to establish? tether, usb, kies, other? have you tried any combination possible?
I just got the phone a couple days ago, I have not managed to get it to be detected by anything yet. I have tried it on a couple Win 7 boxes and also a Vista laptop. I am currently downloading Ubuntu just to rule out the OS factor. I have just been using Kies to install drivers although after reading your post I found this thread:
http://forum.xda-developers.com/showthread.php?t=961956
I'll try that and post results if that is what you mean? I have been trying to establish basically any connection at all for the ultimate goal of getting Odin to actually detect the phone so I can flash it with ClockworkMod Recovery and then an ICS rom. The phone detects the USB cable fine and starts charging and puts the phone into whatever mode I want (kies, mass storage, etc.) but the computer has yet to give any indication that anything is connected to it.
Try with the drivers, but be also sure to enable usb debugging to be able to select a different usb sharing when inserting the cable in case you haven't already.
The drivers installation didn't make any difference and I've tried USB debugging and all 3 connection modes (Kies, mass storage and media player), none of which exhibit any response from the PC.
Edit: Posting from Ubuntu now, same exact thing. Phone detects USB connection, and it doesn't matter which of the connection options I choose as the PC doesn't give any indication that anything has been connected to it.
That's really weird. Does Odin3 (which presumably works at a lower level) sees anything if you put the phone in download mode? ) this way you should be probably able to upgrade somehow.
Sent from my galaxys using XDA App
No unfortunately there is no response from the computer or Odin3 when the phone is in download mode and connected through USB.
that's odd and maybe that's not good at all.
I'm starting to think the problem could be hardware related, especially in a situation where odin can't see the phone in download mode (i.e. no software layer is interfering).
Is there any glaring damage/scratch/missing parts on the usb port?
Sincerely, if I could return it I would try that at this point.
Unless someone else has got anything else to try.
I'll take a good look at it under a scope when I go to work on Monday I guess. Thanks for your input, I'll try to update if I find out anything else!
So I took a look at the port under a scope today and discovered that one of the pins (the middle one) in the micro usb port on the phone seems to be completely gone! Not sure what each pin does but I'm assuming that one is probably used to communicate to whatever the phone is connected to...
Luckily I have access to a parts phone that I can take apart for a replacement port so probably tomorrow I will attempt surgery on the phone! Will report back with further progress after I have done so.
Well I'm happy to report that that was definitely the problem! I replaced the micro USB port on the phone today during my lunch break, put the phone back together and plugged it into a PC here. It immediately detected the phone so I'm pretty happy! Guess I'll be trying out some ICS roms tonight when I get home!
that's great, glad you managed you fix this yourself, well done and enjoy your SGS

Cant connect samsung S1 to PC

Hi,
I'm having a real though time trying to connect my galaxy s1 to a pc. Have tried everything, like kies, direct connection, reseted the device, and no joy.
When I plug the cable it makes that sound as it is connecting but it doesn't show in the PC anywhere, nor even in Device manager.
It can get pwr from the usb cable when is connected; already tried with another cable and same thing.
My final goal is to unlock it.
thanks for any help
have you tried put yoy're phone in depurating mode?
I guess yo mean Debugging mode, as I couldn't found Depurating anywhere. Have selected it and the same effect
HI
I had the same problem after getting nowhere with it, for some reason and I don"t know why, I put it in download mode and then connected it to odin and my PC found it I then disconected it and its been fine eversince.

#Samsung Kies always makes problems on Windows x64 !
##I would recommend, if you got 32-Bit Computer, to use that ;-)
#If you Want just flash over Odin, then is this driver package enough

#The Package is also enough for If you want just to connect to mass Storage (Phone's SD Card)
Don't Forget to Thanks, if it was useful for you!

Hi there.
By direct connection you mean the USB Mass Storage mode, right?
It might be some weird, random problem with the samsung system drivers. I used to have such problems about two years ago, back in the days of Froyo. Have you tried re-installing them? There was a link to proper drivers file in one ICS installation tutorial, and those drivers can be downloaded here. If you go about trying this method, lemme know if it worked.
Cheers.
PS: Unlike diklooc there suggested, do not never EVER go back to x86 OS. That's the worst advice. Kapisch?
Did you check your usb port in System ?
Sometimes it stuck with another lastest device
Hi,
have tried everything, and finally only in a WinXP32 could be abble to get the error shown on the file atached.
But nothing (warnings) come up in Device Manager
Unninstalled everything (kies) and tried to install only the driver and nothing happens.
Should I try to mount it on a linux?
or is it dead?
thanks
i have this problem too
wat chan I do???
my sgs can not connect to my PC
This may help...
Hi there - I don't have the same phone as you, but I did encounter the exact same problem. I've been searching around and it looks like the most common fix was to simply replace the cable. I don't know what kind of cable you have, but my phone (a Samsung Focus i917) uses a mini-usb connector. I found that my Amazon Kindle used the same connector.
When I was using the Samsung cable, I'd get intermittent connects and charge power. The OS would report unknown device. When I switched computer's = same result. I switched to my Kindle cable and the computer instantly recognized the device and installed the drivers. After 12 hours of troubleshooting, factory resetting my phone (blah - lost everything) it turned out to be the cable. I know that this isn't an easy troubleshooting step for most people, because who has an extra cable? I just got lucky that my Kindle uses the same connector. I'm now suspecting (due to the prevalence of this connectivity problem coming from people with Samsung phones - there are a LOT of reported issues) that there is probably a Samsung cable problem in general.
Good luck with your phone.

Nasdriver, I currently have a similar problem but mine is related with Samsung Kies as I can't get either my older SGS1 or my newer Samsung Nexus to get recognized by Kies. I also suspected the cable thing and even read it could be a USB port issue but neither of them was my problem (I have 3 cables and 8 ports on 2 computers that result in the same thing). I can connect other devices with the same cables and they work, so I suspect my problem is focused around the Samsung device drivers.
My advice is if you can go in a systematic manner, first focus on the cable (easiest to replace), if you get the same results with a new cable, then focus on the USB physical port, clean it with some Isopropyl alcohol, if the port works for other devices (camera, other phones, etc..) on the same cable but not with the SGS, then try reinstalling the samsung device drivers.
Oh, and if you want to unlock your phone, the EASY way is to download the Galaxy S Unlock application from the Android market (no affiliation) it's free (but the developer does accept donations) and it WORKS. I won't bore you with my 3 week journey trying to unlock my Bell SGS phone here in Canada, had I found this app first I would have done it in less then 2 min saved myself a LOT of frustration.
Good luck

HD2 Charges but no data!?

Hopefully someone can help with this. I'm running Yuki 2.1 on my phone and my phone will connect to any pc and charge but will not be recognised as a device. Even after removing all USB devices with USBDVIEW i get no luck.
So steps I have tried:-
1.) Restarting everyting, phone and computer.
2.) Hard Reset phone
3.) Uninstalled all phone related software (zune, wp7 sdks etc)
4.) Different USB cables
5.) Disabled virus protection
Now I as far as I am aware I could just flash another Rom through magdlr (havent checked if this will actually work yet) but I only have the one sd card at the minute and because im using Yuki it'll be locked. So without being able to sideload the unlocker am I screwed? or can anyone think of something I can do?
I forgot to mention I also tried connecting to it via Ubuntu and both magdlr and WP7 dont appear to connect yet the phone charges fine. I'm stumped guys, any ideas?
the phone charging has nothing to do with windows desktop recognizing your phone.
what you said about ubuntu doesn't make sense...what are you saying about ubuntu?
i've found sometimes it takes a while for the pc connection to recognize the phone...shutdown phone an pc. try again. don't use pc to charge your phone..use external charger.
go into devices in the control panel..remove hd2 entries...reboot pc, try connecting.
OK what I am saying about both Windows (Multiple versions on multiple computers from Win7 to Xp) and Ubuntu (desktop os) is neither of them recognise the device what so ever, it is not a driver recognition issue, the device is apparentley not connected. There is no sign of it being connected to the PC at all, except for the fact it DOES charge. I have removed all previous drivers (including on my own pc where HD2 appears under devices & printers as suggest above), software and restarted both deivces many times since.
I am not charging my HD2 via the PC, I charge it from the wall. What I am saying is when it is plugged into a computer it does charge but according to the PC's it is does not exist as a connected device. Let alone recognizing the phone. This has only happened since this particular boot of Yuki 2.1, I have had multiple other Roms including this one before and never had this issue before.
I have connected it to computers on which the phone has never been conected to, and others that it has worked on all with multiple cables. So I am under the impression it is a phone issue, unless I have been a real derp and you can think of anything I may not have.
it could be a phone issue. i've always had yuki rom my phone, currently v2.1since first out, and no problems whatsoever. as i said, the phone charging via pc has nothing to do/with the pc recognizing the phone...it's a straight usb port power connection like connecting to any usb port.
see if you have the same issue with a different rom.
Thanks for your help. Think I have sorted it now.. I don't know why I didnt think of it sooner but I checked the usb port on the phone and the internal "pins" had been pressed up against the side of the connection so werent making contact with the cable. Looks like it was happily taking a charge like that but no data connection... seems to have just been a coincidence that after finishing installing yuki again that I was a total drip and mashed the charge into the port bending the pins.
So happy now I can keep my beloved HD2, untill the quad core run of WP8 devices are released.
I had the same problem in my MAGLDR mass storage USB phone connected to the PC but not in WP7.5, eventually was a problem with the cable.
glad to hear it was just misaligned pins.
Might also be the cable. I think I've got a similar problem - using the original USB cable Zune recognices the device, using another cable it doesn't (Unknown hardware). But the phone is charging with both - and I don't see any damaged pins on the phone.
