Was it the exact same problem? It would charge but no connection with the PC and no USB otg?

I dont have any OTG devices, so I dont know. It was on stock ofc.

Had it, wouldnt even charge. A combo of plugging/unplugging multiple times, w/rebooting enabled me to charge it, then i flashed the official 21s or 19s, dont remember now, and it started working. Also, sometimes just reversing the cable (phone side) did the trick.
Try rebooting w/ different cable and see if that helps the pc connectivity issue.

I'll try that, but it seems that there was glitch in the current some sort of fluctuations and it maybe fried post of the USB connector. The thing is I simply can't root and install any custom ROM other than that it is perfect. Thanks for sharing!

Nope... Sold it to someone who claimed to be able to fix it. It's a shame, I loved that phone.

I've just received a "new" Pro3 from Aliexpress which has this exact problem. Although it looks new, the dust and fluff in the USB connector gave away that it's been reconditioned.
I have another 2 of these phones which connect to my PC fine.
The PC doesn't even detect a connection with this one though.
Now I can't unlock and replace EUI with LineageOS. I'm not going to use EUI.

I have the same problem. It is charging but cannot connect to pc. It must be a windows 10 problem, because with windows 7 it connects ok.

Your issue is just the driver, update the drivers on the PC and you will be fine. Also make sure in developer options that usb debugging is turned on and default usb settings are on file transfer mtp.

I have written these instruction many, many times. the answers are here if you search.
Remove all external hard drives from PC
Update PC
Install All in One Tool, use AIT to update android/leeco drivers/adb fastboot/enable system wide privileges.
Enable developer options> oem unlock, adb debugging and file transfer (MTP)
If in TWRP Recovery, the system must be mounted to be seen by the PC
If the drive is encrypted > it has to be formatted ( Not wiped) Reboot to Recovery > Issue resolved

Okay, try using an older version of Twrp Recovery. ( A Non Treble Version)
Use OTG if you have it. Otherwise place te TWRP image on the SD storage > When installing your will need to select install IMG ( instead of zip) Install to Recovery, Reboot to Recovery. Click Mount, select data, and erase all of the encrypted data on your phone by choosing Wipe, Format > type yes, Reboot to Recovery. ( check boxes) you want the the phone to be read/writable.
At this point go to File manager > SD Card> You should only see a TWRP folder > Fo to Wipe Advanced wipe, select everything except your OTG drive > Wipe > Reinstall your Rom, Gapps, and Magisk. Did this work?
If no,
Reboot to TWRP recovery
* Select Advanced Wipe
* Select "Repair or Change File System".
* Select Change File System > Even if its already ext 4 select it again
* Format Data> Yes. Reboot to recovery > Full Wipe > Finished
* Now /data is mounted back. > You should be able to install whatever you want. > hopefully > if not you may have a hardware issue, such as the usb card, flex cables or worse.

@tsongming Good morning friends I have my Leeco Le Pro 3 with no system installed, just twrp working. When plugging the otg or the PC he does not recognize anything, I already bought 3 otg and tested with 4 cables and more than 5 flash drive, all this and without success. I installed all the necessary drivers from which, downloaded the tool all in one, tried the qfil mode, but the phone is not recognized on the PC. Has anyone managed to solve this problem?

I have 3 X720 and one of this has got the same problem.
TWRP 3.2.1.0 could not recognize OTG USB and Internal storage. Now Lineageos doesn' start . The start is in loop.
PC doesn't see X720 also in fastboot when the other two in fastboot works.
I think it's a hardware problem!
I have also chankged Micro USB Charging Dock Port Charger Connector, but nothing is changed.
How could I make?
Thanks

Is your charging problem resolved ?
In my case the phone won't charge anymore.
Do You think that changing the dock port will be the solution ?
Is the change difficult ?

My phone wont promt me to mount my SD card when i connect via USB to my laptop

I tried to figure out how to setup adb, and in the process tried to reinstall HTCSync2.0.25.
Ever since then (it may be a coincidence though) my phone does nothing but charge when i ahve it plugged into my laptop. I tried different cords, ports and computers and still no notification telling me to mount.
Is there a setting that i touched that may have turned off mounting?
Did i somehow delete the drivers? If so, what do i need to download because clearly HTCSync2.0.25 isnt doing anything for me since i tried removing and reinstalling + rebooting several times.
Any tips?
EDIT: Ive never had any problems before and i cant remember if i had any when i first got the phone or not.. I'm on windows 7
are you using stock ROM or? does you phone play sound when it connect to the laptop?
everything is stock htc sense.
no sound is made. its like the phone doesnt exist when i plug it in. it just charges. At first i thought it was my laptop, but then i tried my other computer and it didnt work their either..
Have you tried rebooting your phone?
yes, more than once.
Rebooting hte phone with the sd card unmounted (from the phone settings). Rebooting with usb debugging enabled. rebooting with usb debugging disabled. rebooted my laptop. everything
bad data pins on the usb port on the phone?
i doubt that. it worked fine 2 days ago.
Do you have DoubleTwist installed? I tried it once and it messed up my usb mounting and media scanning.
nopei havent installed any new apps between the time where it worked, and it didnt.
one day it did, the next it didnt.
Maybe its a driver error? wehn you first plug in a new htc magic, will it see the SD card or will it not do anyhting until your have the proper drivers? because i just reinstalled htc sync for the 10th time and it still doesnt see anyhting
Can you mount via recovery?
If yes then it's not hardware, cable or your usb port. Likely rom or app related.
If not then it's hardware, cable or your usb port.
well i dont know how to mount via usb, but the screen says fastboot usb when i plug it in.
Nothing comes up on the computer..

What kind of recovery are you using?
Reboot to recovery and mount the sdcard from there.
Plug it into your computer.
Does a removable disk show up?
Try a different sdcard
Try a different usb cable
Try a different computer even!
If all three fail then it's probably your phone (hardware).
Try to mount via recovery (sdcard in the phone, rebooted to recovery and depending on your recovery version... in this example I'll use Clockwork Recovery go to Partitions Menu > mount USB storage.)
If successful then it's rom related.
If fail then hardware (sdcard, phone hardware, computer hardware, usb cable) related
It's not difficult to troubleshoot. We just need to eliminate possible problems to pinpoint whether it's your sdcard, phone, usb cable or computer.
Thanks forhelping me. I appreciate it.
But I don't know how to mount via bootmenu. Il try a different sd card when I get home.
Also I got the stock recovery. Nothing had ben changed
Alright i just put in another sd card and still nothing. would formatting to factory settings help?
But before i do that, is there an app that backs up all my data and then restores it?

Uhhh.... yeah. There are several apps on the Market that will back up your data and restore it. Mybackup Pro ($$$) and Titanium Backup (Free) are the most popular.
But I would suggest installing a custom recovery first.
Try clockwork (use my signature) by downloading Rom Manager.
As long as you have root, (you do have root right?) then you can easily install a custom recovery.
Honestly though, it sounds like a problem with your computer or cable. If you can access the sdcard from your phone then it doesn't sounds like an issue with the card.
yea i guess its a problem with my phone then. I just did a factory reset and still nothing. I tried different cords on different computers so its unlikely that they're all broken..
And no i dont ahve root. Thats why i needed to connect, i was trying to root my phone!

Yup. It sounds like an issue with the usb port on your phone then.
It seems like it's not recognizing the cable when it's plugged in to switch to enable usb mounting.
but how could this happen so randomly? i had it plugged in and no problems, then when i went to replug it in a minute later nothing happened.
It's not a driver problem?
My computer gave em a popup once saying the device malfunctioned or something

It could be a driver, but if you tried a different computer then it's like you said... it's unlikely that all your computers are having the issue.
Just for the hell of it, uninstall the drivers, plug the phone in and try mounting it.
We just need removable storage and that doesn't take any special drivers at all.
yea thats what i tried yesterday, which still didnt work
i'm on hold with HTC now.. i'll see what they say. it's still under warranty
I cant believe this randomly happened.

Oneplus 2 no OS installed

Hey guys,
Earlier today I wiped my phone while trying to update the system, but when I tried to install the update it failed. That means that I'm now sitting without an OS on my phone, only able to access TWRP Recovery and Fastboot. I've successfully installed adb drivers and all of that, but when connecting the phone to a computer ADB doesn't find any devices and device manager only sees it as an unknown USB device (Device Descriptor Request Failed). I have been seaching for a couple of hours now and have not been able to find anything that works, so I'm hoping that you guys can help.

When I try to update the driver, as it says in step A-7, the only unknown device is the unknown usb device and when I try to update that one with the qc folder, it just says that Windows have determined that it is up to date?

Have you tried connecting to PC while in TWRP recovery ? You should be able to access internal storage using mtp. Then you can copy another rom & flash it.
I have tried connecting to Windows 8.1 on a Macbook Pro while in TWRP Recovery, and that's where it said it was an unknown USB device.

Lets try installing the drivers again. If this doesn't work, then it should be a cable issue OR usb port issue. Try this on another pc.
1. Download Oneplus2 USB drivers -> https://www.androidfilehost.com/?fid=24052804347833370
2. Before installing the drivers, Disable Driver Signature Enforcement. -> https://www.youtube.com/watch?v=NM1MN8QZhnk
3. Install the drivers & Restart.
4. Now try either connecting to pc while in TWRP or fastboot.
you can flash factory image through fastboot

Maybe this is a bit annoying but the best solution is to buy another cable since a few weeks ago I had the same problem, bought a new cable and the problem was solved. Hope this helps
Then flash the OS through TWRP using the advanced tool that allows you to sideload files using adb.

How to enter mtp on recovery/fastboot?
I've done the same thing in the past (erase everything) , the solution that worked for me is this:
1.Always have a twrp back up on a usb stick.
2.Buy a cheap usb 2 type c to usb adaptor.
3.Enter twrp and restore the back up.
This way you do not need a pc/drivers etc.
I hope it helps.

Hey,
1. What version of Windows are you using?
2. Did you try connecting to different devices?
3. Did you try changing the USB Cable? Are you using the one provided with the phone?
4. Did you install the correct drivers?
5. In your dialer, type in *#*#2846579#*#* then select in Background>USB HiSuite, to see if anything happens.
1. Windows 7
2. Yes, on the same thing.
3. Yes, I tried 2 others
4. Previously everything was working properly
5. Nothing.. :c

Also, are you using a stock or custom ROM? What version?
Try let Windows install the generic drivers and then see if it helps you to fix the issue.
a) Open Device Manager by clicking the Start button, then Device Manager in the search box.*
b) If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
c) Look for the device under USB [Universal Serial bus] host controller, right click on it and select Uninstall.
d) Reboot the computer.
e) On reboot, Windows 7 should re-install the drivers automatically.
Stock B610
Still nothing..
Same thing happened to me once, but on custom ROM
You may try my solution and report if it works
For me the solution was an option in "developer options" called "select USB configuration" I had to manually select MTP..
IDK if the this option present in the stock ROM.
There is an option, but it also does not help ..
The other roms also do not work.

Bump.
Could it be that you dropped your phone and the port got some damage? Does you phone charge properly?
Also, if you install de ADB drivers and HiSuite, does the PC recognize the phone?
It puzzles me that you tried different cables, different PCs and different ROMs and the issue still persists so perhaps you have some hardware issues or incorrect drivers.
yes, it fell to me. yes, it loads properly.
does not recognize anymore.

I have been out of the custom recovery world too long and never tried on a watch before. Trying to flash twrp on my new TW Pro (H) so I can flash janjans rom. Have ADB and drivers (windows 7), have twrp.img ready.
cmd prompt not recognizing adb command. Cant remember how to proceed...how to open fasboot, unlock bootloader.
I know im missing something simple but stuck. Can anyone help jumpstart me?
Update: Got twrp installed after flailing about for awhile. Bottom line, operator error.
This may be the wrong place to post, but I can't seem to find my issue anywhere and I'm getting a little desperate.
I'm Stuck! Accidentally deleted 'system' int twrp when deleting data for a reset for the watch. Now no OS installed and computer doesn't want to recognize the ticwatch pro through usb (directly attached to dock and then usb to windows 10). I'm not sure it's a driver issue because it should at least be recognized in device manager as 'unknown' but nothing is showing. I now only have bootloader and twrp recovery on my watch. I have everything I need to reinstall the os, but without a way to connect to the watch I can't move the files to the watch to flash it, nor can I connect through usb to push them over! I'm stuck! I'm missing something simple I'm sure, but I don't know what? I just want a way to connect the watch from it's dock to windows 10 through usb cable from watch dock. Then I'm good to go. But I can't.
HELP Please!

Did you try running fastboot from bootloader? Also maybe try sideload the rom from twrp, that worked for me.

That is probably a faulty USB cable, try a different cable or a different PC, Windows 10 should recognize your watch automatically and if you have generic adb drivers previously installed, it should work.
You may also try to manually install the drivers from here:

Thanks. I've tried three different chargers (though I'm not sure if the other two that I bought are actually capable of transmitting data) and three different computers. I ordered a new charger that says it is able to transmit data, so hopefully when that arrives it will work. Makes no sense to me that I can get into bootloader and twrp and yet not see the watch in device manager.

Thanks for the reply. I've got 4 different chargers (including the oem one) two of the additional ones I have state they are capable of data sync. I've tried them on 3 different computers and the watch doesn't not show in device manager, recognized or otherwise. I just can't see this as a cable issue, but I don't know what else to think. I just received the newest sync cable I ordered the other day (now my fourth) and still nothing. I'm stuck. If it would at least show in device manager then it would only be a matter of drivers, but it doesn't. Seems a little odd to me that it stopped when I accidentally deleted the OS. The OS isn't even required for bootloader or TWRP and both of those load on the watch. I can't figure it out and I opened a repair ticket with Mobvoi a few days ago, but there has been no response yet. So frustrating!

You deleted the OS? What do you mean by that? Is the watch still working on its own?
Sounds to me like a faulty connector, I would send it back if it is still under warranty.
I wiped the system folder by mistake. I got click happy when doing an advanced wipe. My fat thumbs ticked the system folder. So no OS installed now. Just bootloader and TWRP. But since the watch isn't recognized by any PC on any of the 4 cables I have, I can't move a Rom on to it to flash it. Nor can I push one over on adb as neither fastboot in bootloader or adb in TWRP see the watch. Not a driver issue since I've tried every one I could find and because device manager doesn't see the watch at all, know or unknown.

Try 1. Flash boot.img via fastboot
2. Reboot and connect, check via adb if it's detected
3. Install via sideload ROM
(adb sideload file.zip)
This issue was that I couldn't connect with fastboot at all. That being said, it turns out the problem was with the watch itself. Mobvoi, replaced the watch with a brand new one free of charge so it's all good now.
Any chance you have, or know of, a TWRP for the TicWatch E2/S2 ?
Would be much appreciated.
Hey, is it possible to connect a SD card or usb flash drive to the watch via otg when booted into twrp to create a full backup?
Hello, what would I need to do in order to port this to the TicWatch Pro 2020? The hardware is almost identical, except it has more RAM, the codename is catfish_ext. I have an unlocked bootloader and tried to boot this recovery, but I get FAILED (remote: 'dtb not found').
EDIT: Nevermind, I have found that the recovery for the 4G EU verison also works with mine. Here is the link to a working image: https://drive.google.com/file/d/1XNejRoLecLeadEj1CAW_zrTUP5bkUJZ8/view?usp=sharing

Nexus 6p stuck in twrp with no os and no connection to pc

i made the boneheaded mistake of deleting everything off my phone in twrp (3.2.1-0) and ive had little success in trying to recover it.
1. my pc will not recognize it when its plugged in, this was also an issue when it had an os on it. ive tried to install the google usb drivers as well as the hisuite drivers with no success
2. i bought a usb otg adapter so i could possibly push the new os through there but when ever i try i get 0mb when trying to select the storage in the mount section of twrp. ive also tried reformatting the usb multiple times but that didnt work either.
3. there is no connectivity while in fastboot as well as adb
I'm caught in a tight situation and don't have the means to buy a new phone if anyone could help me out i would greatly appreciate it

Powerdown your phone and boot to bootloader by pressing powerkey and holding vol- then connect to your computer you should see the Nexus 6p on your pc and. from your computer download any rom of your like,gapps,root optional and copy it to your internal storage. Then just flash.

that doesnt work either. i have all of the appropriate drivers and still nothing.
That could be your pc. Try a different port or even better another pc.
