Root without PC (USB not working) - Xiaomi Mi Mix 2S Questions & Answers

Hey guys,
Bit of an odd one... My mix 2s wont recognise to my PC, no matter what i do and due to a bug in miui, i dont have quick charge. It's a pretty common bug and theres supposedly a fix, but it requires root.
Im currently running MIUI 10 global 10.0.2.1.0 .
Given i cant unlock my bootloader without my PC connecting, am i stuck, or is there a workaround?
Thank you if you can help

Is your cable perhaps broken?

USB accessories commonly use 4 pins/wires: V+ and V- for power supply; D+ and D- for data transferring
Probably your cable, PC or phone port has D+ or D- broken.
Check them out.
I'm pretty secure to say root won't fix it.

I have multiple genuine and aftermarket quality cables.
I know my USB issue sounds hardware, but im quite certain its software based.
Reason is : my mi6 still quick charged and had MTP via pc before i updated it to miui10 as well .
Now i can only quick charge the mi6 when the phone is off.
Thanks for your help all the same

I'll bite, what type of USB port are you plugging into on your PC?

Usb 2, usb 3, front panel, rear panel... Same result.
Trickle charge. No usb options. Usb debug etc all set

If you update yo miui developer update app in the system, do you think that it would solve your issue?
Since your pc does not detect your phone, I don't think that it will fast chare even with the root fix you mentioned. The charger communicates with the phone over the usb data lines, if there is a fault, they can not communicate, therefore no fast charging.. it might be a faulty usb socket or something

I have the same problem. quick charge + OTG not work. please help..
*hard reset + change to antoher cable not solved

USB 3.0 Problem

Hi!
Got my Note yesterday, now I got a problem, again. I can't get it work on USB 3.0 no matter what I do (I'm sure about this but I ask this anyway: am I right that SM-P905 have USB 3.0?)
Okay, to the problem:
When connected to USB 3.0 I don't have option to choose USB 3, I only got MTP and PTP
- I updated Kies 3
- I reinstalled drivers (from Kies)
- I have 2 USB 3.0 ports on my PC so not so many to test but:
USB 3.0 works on my Note 3 (SM-N9005) on both USB-ports, It also works well with my Note Pro USB-cable
Note Pro doesn't work (don't give even option to choose USB 3 mode) on any of these two ports. I also tried both ports using my Note 3 USB-cable, but still no luck
So any ideas?
ps. I got ASUS motherboard and I found out someones having similar problems with their Android devices. Reason was ASUS Ai Charger -utility, but I don't have that one never ever istalled on my PC. Oooh, and one more thing, I'm using Win 7 Home Premium (x64)
---------------------------------------------------------------------
Updating BIOS and reinstalling Windows did the trick, now it works like it should
What exactly makes you say it doesn't work? Are you completely unable to transfer data to/from the tablet to a PC, are you not seeing a difference between transfer speeds using a USB 2.0 cable vs a 3.0 cable, OR is the appearance of everything working there but you are wanting the USB 3.0 nag screen to pop up to give you an indication that you're indeed using USB 3.0 ?

When I connect Note to PC USB 3.0 port, pull down notification bar and click USB notification, I get ONLY option to use MTP or PTP. USB 3.0 is not listed there as option. I also transferred about <10Gb size file to Note and it took about 50min, which really is loooooong time..
Okay, here is screenshot about what I meant. Can you please say how it's in your tablet.

Same - Mine connects MTP and I can see it and transfer files but on my tablet I get a Icon in the top tray that says connected to USB 3.0
Same here, when I'm getting a USB 3.0 connection to my PC I'll get the 3.0 indication in the notification screen.
I can't get 3.0 to work with my rMBP but it works with my Windows 7 based workstation and I can definitely see an increase in file transfer speed to the tablet when the USB 3.0 cable is used in a USB 3.0 port. Just did a test from a hard drive on my PC to the tablet, 2.1GB file transferred to internal memory on the Note Pro in 1:18 using a USB 2.0 cable and 0:48 using the stock USB 3.0 cable so I'm getting about 45mb/s with 3.0 and 27mb/s with 2.0.
Okay thanks. Tomorrow I'll check again if notification bar shows USB 3 or not, can't remember right now (still got thought that not). I'll get back here and tell if it's working or not.
EDIT: Yup, no USB 3.0 connection, in notifiction area there is that standard USB icon and it's not saying 3.0
EDIT2: Is there some way to find out if Note charges using USB 3.0? Shouldn't the 3.0 be a lot faster on recharging than 2.0, but how I can know which one it uses?
Sent from my SM-N9005 using XDA Premium HD app
Okay, back to subject..
Does USB 3.0 affect anyway to charging speed? Like if I use stock wall charger with 2.0 or 3.0 cable?
What's your charging speed? I did test and from 50% to 55% it took 15 minutes and from 50% to 65% 45 minutes (which makes average 5%/15min)
To charge I used stock wall charger and stock USB 3.0 cable. I didn't use my NP while charging and mobile data / wifi was OFF
Can you please check how fast is your Note Pro to charge? I still can't make my note to work on 3.0 mode when connected to my PC and I'm trying to find is the problem on my PC or Note before sending this to repair
How about trying Gsam Battery Monitor and observing the charging characteristics that way. It will give you charging current.

With wall charher charging current is 1900mAh, which is normal I think.
Now, if I plug my NP to my computers USB 3.0 port, I get BSOD --> PC reboots and I plug again --> now it works, but still not on USB 3.0 mode. So it could be with drivers or something, tried again install device drivers with Kies 3 but no luck. What could I do? I don't have skills to remove all the drivers and start from clean table (any other way than formatting my pc and that's not gonna happer for a while )
Any ideas?
Okay, just tried with laptop (Win 8.1) and my NP is ok, it connected using USB 3.0.
Now what, if my external HDD and Note 3 works on my own PC via 3.0, what I can do to make my Note Pro work also??
Problem have to be with drivers or something..
Mine doesn't show the "Use USB3.0" option that my Note 3 shows, but it clearly says "Connected as a media device via USB3.0" in the notification bar. (See attached screnshot)
Also, it just copied 1.03GB in 16 seconds from my laptop to my NotePro.
Clearly they removed the USB 3.0 setting from the menu, and it is now done automatically.

I'd start with USBDEVIEW. Google it. Run that with no android devices connected to the PC. Uninstall all drivers related to any android device and reboot the computer. Then try again.
If that doesn't work, consider repeating that, rebooting and then updating the chipset drivers for your motherboard.
After that, I'm out of ideas.
Us Mac users have the same issue; the tablet is simply not recognized as a USB 3.0 device on my rMBP which is running Mavericks. It doesn't matter if I'm running windows as a virtual machine in VMWare Fusion or not so I'm thinking its at the driver level of Mavericks.

I copied 1.42GB file from my USB 3.0 HD to my ext. card - that took 5:52.
I just can't get 3.0 connection to work with NP (see attachment), Note 3 works fine.

Thank you for help. I uninstalled all drivers related to Android and/or Samsung, restarted my PC, connected NP and still not working. At this point I restarted computer again but that didn't help either... Where the heck can that problem be?
I also tried killing all processes that I knew I can safely kill from my PC (In hope if some program/process is doing harm for USB 3.0 connection) but no luck..

I updated them twice, just to be sure. I got 2x USB 3.0 ports on my PC.
My external HD and Note 3 works well with both of them. And Note 3 also works with NP 12.2 cable.
Just my NP wont work no matter which port or cable I use.
On my friends laptop NP 12.2 with the cable that came in the box works well, immediately connects as 3.0 device.
I think I'll quit with this. Don't have the knowledge find out where the problem is.. I thought maby BIOS update might help, but since everything else works fine, I wont do that because the risk of totally f*** up my computer.
But if anyone here got any other/more ideas, I'm listening

You said you had an ASUS motherboard, right? I'd go ahead and update the BIOS, it's pretty fool proof with the newer ones (which you have USB3.0, so it's a safe assumption that it's new enough.)
I also have an Asus motherboard, funny thing is, my Note Pro does show the USB3.0 indicator in the notification bar, but I'm copying files over right now via Linux and it's copying at 9.9MB/s. That's pretty horrible. Added to that, my Note Pro won't charge from the USB port on my computer, but it will from the wall charger. It has a big red X over the battery when plugged into the PC. So I'm not sure if that's somehow related.
Another thought about both of our problems, is that maybe the cable is a little loose or something is in the port-hole. I know mine was a bit flakey for a bit there (as in I would plug it in, create a folder... then tried to rename it and it said it couldn't access the device... I had to try it three times after unplugging and plugging it back in.)
It doesn't make sense though that it's a BIOS and/or driver issue if you also have a Note 3 and it's working through USB3. I know on mine, when I tried it in Linux (can't recall if I did under Windows), it was extremely flakey there too. The Note Pro just autodetected it, but still copied slowly. I'll have to try that under Windows as well now.

Yes, you may want to update your BIOS.
(For the record, I'm using an Asus N76VB with the factory BIOS, no issue).
Hm, maybe a silly suggestion... Are you using any type of USB charging setting? I know some of these Asus motherboards come with an option to overvolt the USB port to enable fast charging.

Not related. A USBport doesn't supply enough amperé to register as charging. Even my old Galaxy Tab 2 10,1 has that issue.

I have that issue with my Note 3 and even my TF700T since day 1. It's an MTP bug. And now since 4.4.2 I can't rename anything on my Note 3 without explorer.exe crashing. Different pc's, different OS's, different cables, no difference.

I did read somewhere that Asus AI Suite (program to tune up voltage or something for usb charging) can somehow do "harm" to USB3 connection, but I don't have that one even installed.

Well... I too see that red x on top but my tablet charges anyway (slowly byt still charges)
The funny thing here is like I said: My Note 3 works perfectly when plugged to USB3, but my NP doesn't like recognize that it's plugged to 3.0 port. It just acts like using 2.0. Same PC, same cable, different device.

Yeah, I know mine isn't charging because I watched, even after plugging it into my computer, it slowly go from 70% battery down to 65%.
When looking at what is hogging all the battery, it's the retarded Indexing service. I'm still in the process of seeing if there's a fix for that, but it really seems like it's having an issue (which would also explain why mounting it on the computer is flakey, since they could be trying to read the same file systems.) Oddly, my Note 3 doesn't have any of these issues (except actually mounting as USB3). In fact, I was starting to suspect my PC at work had crap USB ports, but it's just the stupid Blackberry cable (it only successfully charges the blackberry, not my Note 3 or anything besides my mouse that I've plugged into it.)

Help figuring out what's broken with my OnePlus One

Hello everyone,
A couple of weeks ago my USB data connection on my OnePlus One has stopped working.
This means that no connection is even detected on any computer.
This is not a driver issue as the computer doesn't even notice anything has plugged in.
I think it's not a software/ROM issue because the same applies to fastboot mode and recovery mode - no data connection, no "usb plugged in" sound on any computer, no device showing up.
It's also not a cable issue, as the same cable works on other OnePlus One's and I've tried many different known-to-be-working cables.
More facts:
1) When plugging to a computer USB port - the battery icon shows the charging (lightning) symbol for a half a second and disappears and it won't charge. The computer, of course, doesn't see a usb device plugged.
2) When connecting to an AC charger - it charges just fine.
3) I already tried replacing the dock connector and flat cable unit with a new one - did not solve the issue, which means the dock connector is fine.
Any insight on this will be greatly appreciated!
Thanks!

By dock connector, you mean the USB port? Typically, this issue arises when the pins in the USB port get damaged. I don't know how the rest works out, but if that particular section of pins have to communicate throughout the rest of the motherboard, perhaps the trail responsible for that may have somehow gotten damaged. This is a clueless theory, someone with more electrical/motherboard experience can verify this.
What I do know is that once the micro USB port has been replaced on the phone, the issue should be fixed. It happened to an S3 I still have and I got it replaced by a friend. Sadly, it happened to me at the wrong time since i had wiped the entire OS and internal storage and was relying on my USB OTG cable and a flash drive which contained a rare rom called Sonic Open Kang Project (SOKP).
DO NOTE that this has also been an issue with me on the software side of certain devices. I uave had practically every flagship device out there and have come across a point where this happens on both stock and custom roms. My Optimus G did it on custom roms, and my Nexus 7 2012 occasionally on stock. There were other devices I cannot remember but sometimes factory resets or replacing the rom helps. However, you did state that the result is still the same on fastboot/recovery, so this seems to be more on the hardware side.
I replaced the USB connector (including it's flex cable) entirely. Did not solve the issue.
What else could be wrong?

You running a custom recovery? If so, see if you can toggle the mtp on/off reboot with each back to recovery. Use the tools to check the filesystem, permissions, etc.
Could pins have damaged?
Well, I did replace the USB connector with a new one, so if pins are damaged it's gotta be on the motherboard side, and I can think of no reason why that would ever happen.
As for recovery, I'm running TWRP and I'm not sure I understand what you meant I should try. Can you elaborate?
Thanks

Defective USB Port? Data connection and Quick Charge not working anymore

Hello,
I recently flashed TWRP and CyanogenMod 13 on my Mi4. It was working quite well, I had some problems with the rotation sensor and some bugs in the software, but Quick Charge and also the Connection to the PC worked without problems.
Today when I was on my way home I was charging my Mi4 with a Qalcomm 2.0 Quick Charge Powerbank from Aukey (i have used it in the past on other phones, always worked great), but it seems that the USB cable was broken, it was charging very slowly and it also seemed to have a defective contact (the cable charged if i moved it around a bit, but in certain positions it wouldn't charge).
However, when i got home and plugged it in, I noticed that the phone also charged very slowly with the charger, so I thought that I would just flash MIUI back on the device to fix it, maybe it was a problem with Cyanogenmod. But that didn't work at all, the phone couldn't connect to the pc.
So, here's my problem: The PC can't detect the phone and it also seems, that the phone doesn't recognize, that its connected to a pc. Charging via the USB ist still working, but very slow. Also Quick Charging isn't working, it doesn't matter which charger or cable I use, it's always slow. When I connect the phone to the charger or the PC it takes like 5 seconds to recognize, that a cable is connected, then it starts (slow) charging.
The phone doesn't show up in the windows device manager at all (there are no unkown devices shown, the pc just doesn't react when you connect the phone). Also there is no message on the phone when you connect it (usually you can choose if you want the use your phone as a usb drive or just charge it). I also tried to activate MTP in the developer settings on the phone and turning USB Debugging On/Off, but it didn't help.
I managed to download a MIUI Rom from xiaomi.eu with the phone and installed it with TWRP, but it didn't help. So I think I actually broke the USB Port of my phone with a defective Micro USB Cable. The phone can still charge (very very slowly, no quick charge possible), but I can't connect it to the PC anymore. The pc also won't detect the phone when it's in fastboot mode.
I tried to look it up on the internet, but all I found were people with driver problems, and I don't think that I have a driver problem, because it seems like there is no connection between PC and Phone besides the charging.
Anyone knows something about this? Is it even possible to just break the data connection and the quick charging with a defective cable?

No, I didn't find a solution for the problem. Phone is still not working, I even ordered a new charging port, but I made a mistake and ordered one for the LTE version. I have the 3g version, so the new charging port didn't even work with my phone. I don't want to spend any more money on it, so I just gave up on fixing it.
Same problem, and I am also stucked in recovery for now, never will buy phone without SdCard now...

USB Device not recognized / No fast charge

So I've had my S7 for around two months now, and all of a sudden fast charging just stopped working. Thought, oh, must be using the wrong cable (have loads of them micro USB cables floating around)
Now I'm certain I'm using the official Samsung fast charge plug and cable that came with the phone, and still no fast charge. When I try to plug into my Windows 10 Desktop or Laptop I have a message that says the device can't be recognized
Phone has already been rooted and flashed with a custom rom. Didn't think that was the issue as it wouldn't even show the mounted storage in TWRP, or identify the phone in ODIN.
Now I've flashed back to the stock rom that I made a backup of when I had the phone, and I still have the same problem!! Can't access internal / external storage using the supplied USB cable and can't fast charge.
I'm thinking the USB port on the device is just knackard.. but really, I've looked after it so well I fail to see how this could happen, unless it's a common fault.
Might just get a wireless fast charger, but do you guys have anything else I can try before giving up on the USB connectivity?
Cheers
try to connect to a different pc, if same it means your usb connector is faulty
Sounds more like the cable is bad tbh, you won't get fast charge from a PC USB port, only from the Samsung charger
But if the device isn't recognised by the PC, and won't fast charge from the charger, the common thing between them is the cable
Possible it's the phone USB port, but more likely the cable is bad
Afaik certain cables can not fast charge either, so chances are the ones you have lying around that are not the official cable can not support it
Genuine Samsung USB cable is white with the USB port symbol on both ends and the phone end has two small ridges to grip when inserting and removing it, should help identify it
Yep I'm using the official cable and fast charger
I'm trying to fast charge via the fast charger and not USB. Only trying USB to access the internal / external storage.
Tried on my desktop and laptop and both have the same issue where my old HTC m8 connects without any issue.

To fast charge I've tried the original Samsung cable with the fast charge plug.
To connect to the PC I've used x3 different cables that all work with my HTC one m8. With all of them I get device not recognised. Already tried installing Samsung switch and reinstalling drivers which didn't work.

I mean for the HTC, does the Samsung fast charge cable work to connect to the PC?
Does sound possible the phones USB port is faulty if you can't get any connection at all to the PC with multiple cables

Unfortunately not. Well it's been rooted and flashed so I guess not.
Ordered a wireless fast charger so hopefully that will see me through and WiFi network for file transfers.
I reckon the USB port will need replacing but I'm not really inclined to do that myself.
Just noticed you said you flashed back to stock using a backup you made
Have you tried stock using ODIN and 100% stock files, using CSC to reset?
My dad has a5 2016 with the same issue, and no warranty. I bought flex + connector , replaced it and still nothing. No fast charge ( it takes cca 4hrs to charge it fully ) and no usb connectivity. I gave up on that
@ClowsTyle
Any luck? I seen your recent post in another thread and it sounds like you tried to replace the USB but that didn't work.
I'm having the exact same issue now. Device suddenly stopped fast charging, Windows does not recognize it when plugged into PC. I ordered a new cable to double check and also tried on different computers. I also tried reinstalling drivers, but nothing has worked.
Hi my is doing the same thing no Fast charge and no pc connection, did anybody find out what happen with yours ?
You have to change power ic s535 for s7 edge.
When usb gets moisture power ic will damage.
I have same problem my phone charging 0-100 6hours but ı install notorious kernel and it takes 3 hours it is better than 6 hours
Same Issue
I've had the same issue for the past 3 weeks now and I've tried everything I know...
1. Tested cable and charger with another S7 and they work fine.
2. Factory Reset.
3. Changed the USB port chip.
4. Turned on "Low Battery Dump".
So far, the issue hasn't changed.
was this issue solved?
I´m having same issues whit my galaxy s7 active, I can not fast charge my phone no matter what cable I use, then noticed that evrytime I plug it to any computer it says the devicescan not be recognized, I´m about to buy a new charging port and install it, but I want to make shure this is not a software related issue.
I´ve tried several cables and several laptops/ pc´s
I´ve factory reseted my device and turned on low battery dump, wiped cache partition, and problem still there...
The charger could be faulty/damaged did you try a different charger?

I also have the same issue with my phone the phone charges but not recognize and also tried to change settings on phone and nothing? And my other samsung phone works and nothing wrong with USB tried to install smansung drivers on PC and still same issue.
I tried a different USB and nothing works and different ports on my comp.
My ports works with my other samsung phone so not sure why not with the S7?
Is the USB faulty?

PC not recognizing my phone thru usb

I recently bought a Google Pixel it's all working fine
But when I plug it on my PC it doesn't get recognized even though the phone is charging I don't get any notification that the phone is plugged through USB I have all the drivers installed
Here are the errors I'm getting: "Unknown USB Device (Device Descriptor Request Failed)" and "Windows has stopped this device because it has reported problems. (Code 43)" please help I've moved from iOS recently I don't want to refund I freaking love this phone! and i'm starting to get desperate.
Thanks
Not for the Pixel 2 but I thought it'd be the same case plus I need help ASAP cause I'm leaving country soon!
Are you connecting it using the cable that it came with? If you are, try a different port or reboot your phone and see if that helps. You can also get into the developer settings and tell it to MTP rather than USB Charging. Sometimes that helps. You can also try different cables, (if desktop) use the usb ports on the back of the computer rather than the front.

Yeah I did it all. It just doesn't wanna work
The cable it comes with is garbage. Use that only for charging and go buy a good USB C or USB A to C cable (for transfer, adb, etc. I've had better luck with the A to C cables).

I am using an original S8 one, tried with my friend's Google pixel original one and tried with a Chinese crap all three of em same ting
Make sure you are plugging into a USB 2.0 port. If all you have are 3.X ports you need to enable USB debugging in Developer options. If you are plugging into a desktop use the ports on the back of the machine.

Perhaps you should have stuck with iOS then?

It's too late for that now mate
I don't bother connecting with a cable. I use the free app 'Airdroid'. It gives you a url to use on your computer and as long as both your phone and computer are on the same network you can see all your files, photos, messages etc. on your computer screen. Very easy to move files either way and do all sorts of other things. Very slick.
BTW, you don't need to setup an Airdroid account just skip that bit.

Nah I'm doing this so I can root n stuff
You don't need pc to recognize device as a drive via USB for file recognition to root and stuff. Just use adb push and pull. That's of course if it is recognized by adb. Mine is that way as not recognize mtp drivers but adb is fine

I had the same issue when I first got my phone. Initially, the only way I was able to get it to work was plugging directly into a USB port on the PC....it wouldn't work on any USB hub. I ordered a Anker Powerline II cable (my hub was Anker so I figured it would have the best luck) and it worked. No other cable would work...not sure why. Also, I didn't have to enable debugging (I had tried that before and it still didn't work)...I was able to go into Settings and change USB from charge only to file transfer.

I've had the same issue - it ended up being a bad cable.
I know you probably checked this, but... did you update the Google drivers on your PC? My phone wan't recognized until I installed the latest from Google.
Just use an a to c cable. If you're using the adapter that came with your pixel, it won't work. And yeah everyone else is right, use the 2.0 port
Apparently 8.1 fcuked up usb 3.x connections such that you can't even use them for data, only usb 2.0 for now, it's super annoying. There's an issue tracker for it if you want to star it.
I use Solid Explorer and the ftp server to connect to Win 10 for file transfers atm
I had the same problem. After I finally switched to my one USB 2.0 port, I was subsequently able to use my 3.0 ports again. It was a while ago, so I don't remember the details, but I think I updated the driver for the device that was reporting as active in Windows Device Manager while I was connected via the 2.0 port.

Would be interesting if you could share your driver info - no one I've seen online has fixed this!
