I have a strange issue, when i connect my phone over USB the computer does not recognize my phone, there are no options in the notifications, when i enable usb debugging the phone just reboots. When I enter TWRP and enable MTP there everything works fine. I have CM12 installed since the first nightly and dont know currently when the problem occured but I always flash the latest nightly available. I would like to prevent a factory reset to fix things.
Deactivate USB debugging, connect your phone to your PC and go to Settings -> Storage. In the upper right corner you can choose the connection. Look if MTP is enabled there Hope this helps
the problem is, everything regarding usb storage is greyed out and android debugging is enabeld as soon as i disable it i get a soft reboot and when i reenter developer settings its enabled again
Ah, don't know it then. Factory reset would solve it pretty sure. But since you said you don't want to wait a few more hours.. maybe someone knows a better solution.
Oh hey, 1000th post by the way
congratulations I think i'll just factory reset, does anyone know how i can backup multi-user accounts with their settings?

ok i am going ballistic
wth is the deal, i cant get adb working for nothing.
it was working, then i flashed 2.2 and had to many FC's so went back to 2.1 update 1
and now i cant get adb to work for nothing.
what is the correct procedure here to connect with the phone.
usb debugging is typically on, but people say "choose usb storage" as the usb mode, well when doing that usb debug is disabled.
so i imagine that is why.
so what the hell is going on? i am so confused and about ready to smash the phone.

As far as I know you don't mount the SD card at all when using ADB, so just enable USB debugging (i've noticed once you do this the usb setting seems to default to Kies, and if you try to change that it will disable the debug, so just select the debug and leave the usb setting alone) plug the phone in an when it asks you to mount the sd card, don't do it. Then, in theory, you should be able to use ADB. Sorry if you've already tried this....
hi, i'm having problem with USB debugging.
i just update manually from 2.3.2 CM7 RC1 to 2.3.3 with the link.
now i'm having some trouble, one of them is i can't seems to connect my nexus s to USB-debugging mode. I already check the "USB-debugging", usually i see "USB-debugging is connected" under notification area, but now i don't see it at all.
other problem is my home button is also screw up and my lockscreen is gone (maybe because i'm messing with it in CM7), so i need to get my root back on but i can't seems to root it back without USB-debugging..
Any help is appreciated, thx..
Hi,
I noticed yesterday that the USB on my OPO wasn't working anymore (charging works, but the phone isn't recognized on my PC, and doesn't recognize USB drive or any other storage)
I have searched on hundreds of threads on hundreds of different forums, but nothing works for me
Before you answer :
Yes USB debugging is enabled
Yes USB configuration is set to MTP
No I don't have " three dots" in storage and USB to enable MTP or idk what
No I don't have any notification when I plug my phone to enable MTP mode
Yes OPO driver is installed
Yes I tried to uninstall it
Yes I rebooted my PC, my phone, tired on different PCs and different OSs.
I think that's all.

my friend had the same problem on his asus zenfone 5, the guys at the service center said that the USB ic needs to be changed. just an advice try not to hard brick your phone untill you rectify this, cos my friend hardbricked his phone with this problem and he ended up in trouble.
Thank you for your reply.
I think I have the same problem... I asked the same question on the official OnePlus forum, and someone told me to do a factory reset, and if the problem was still here after that, that means it's probably hardware related. So I did a factory reset, and the problem is still here...
I'll follow your advice because I know it will get worse if I brick my phone, I will contact OnePlus tomorrow
Title should say USB my fat fingers ! phone is completely stock no attempts to root. Enabled developer options fine. toggle the USB debugging switch. Get the Allow USB debugging? pop up. Click ok. Don't get any kind of debugging enabled notification. Restore default settings button is shown at the bottom of screen - i ignore this. Hit home or settings menu then go back to Developer options and the USB debugging switch is toggled off again. I tried restarting, developer options has stayed visible in settings but still can't get USB debugging to stick. PLEASE any suggestions what i'm missing?? Thanks
I also have the same problem with my mate 9. Allow usb debugging setting automatically toggles off as soon as I leave the settings menu.
Hi boys..
reasonable for this behaviour are the developer mode switches 1.) "Allow ADB debugging in charge only mode" and 2.) "Always prompt when connecting to USB"!!!
If switch 1.) is not set to "on", and switch 2.) is not set to "off", the switch "debugging allowed" would be cancelled every time you leave this menu!
So it does, what it have to do! Cancelling debug mode if phone would be connected to any other device without transferring data (if only charged). Easy, or not?

hi man
i have a problem
my phone is huawei p40 pro
how to fix usb c port of the phone not function only charging , no fastboot ,no mtp ,no usb debugging ,no hdb
this is what i did
at the first usb c works fine
untill i did downgraded from version 11.0.0.190(c185R3) to version EMUI 11.0.0.153(c185R3)
i used hisuite proxy method and i got firmwares from https://www.firmfinder.ml/
after phone bootup 11.0.0.153 firmware , it seems usb c port disabled and just charging works
even i couldn't toggle usb debugging and change usb mode to MTP
after that i again downgraded to 10.1.0.114(c185R3) and nothing change . still usb c disabled
so i couldn't connect my phone to usb , and even i couldn't use usb otg
so i decided to use my phone itself's online update. i run updating first to 10.1.0.183 and nothing changed
again updated with itself's online update. update to 11.0.0.153 and still nothing changed
finaly the last firmware update. i updated with itself's online update to 11.0.0.195 . and see usb c work , even usb otg , and usb debugging and MTP , all works perfect
can you explain what happend on my phone and why usb don't work when i use hisuite proxy method ?
i did it again and again , all same results
It seems that the official update with the phone itself ( without pc ) is the only way to solve the problem
today some one tells me another way ,
can anyone test this way?

Hi there,
Huawei July Patch 2021 close all posibility to downgrade the FIRMWARE, it can be done with Hisuite Proxy but you have to choose the correct FIRMWARE and suitable to your Phone region. Once it done you can fix the "DISABLE USB" by doing OTA update to latest FIRMWARE to make it works.
When you choose the wrong cust/preload/mainFW your phone will be locked with that current FIRMWARE with "DISABLE USB" forever, you can solve this by searching the correct FIRMWARE and flash it using NMCARD the FIRMWARE should be a Higher than your Current FIRMWARE INSTALLED. after all done you can get OTA update and do OTA Update to latest FIRMWARE to make USB WORK.
Please be NOTED : Testpoin Not Working with latest July 2021 Firmware Patch so Huawei Block any downgrade posibility
I found 2 Brand USB Thumbdrive which is work with "DISABLE USB" you can do such Dload or restore Lzplay to instal GMS before update with OTA UPDATE. Here I attached the USB Thumb Drive.

Hi guys, i'm getting this problem and cant connect to pc and i think i've tried it all.
when i connect my phone to the PC, it stars charging but my pc doesn't recognize the device, and my phone doesn't show the notification to make it file transfer.
Could it be a computer issue?
it seems not, i've uninstalled and installed drivers (ADB and Fastboot, oneplus drivers, google drivers) and the problem persist, and even try it on another computer and its the same, the phone does not appear even on Device Manager.
Could it be the Cable?
I don't think so, i'm using the original oneplus cable, it use to work really well before, and i have even connect other phone with the same cable and the other phone is recognize by the computer, so it''s not a cable issue... but I still when to a Tech-store and try other USB-C cables with their computer but my issue still persist (phone isn't recognize, just charge).
Could it be a phone software issue?
Maybe? but i discover this issue 3 weeks ago and a i was on EVOX rom and i thought it would be solved flashing another rom, and i CLEAN FLASH Resurrection Remix Rom, but then the problem was still there!
cant connect even on FASTBOOT MODE...
BTW, before installing RR, i Installed OOS 10.3.4, and still my computer doesnt recognize the phone, YES i have enabled developer options and USB debugging is enabled, and USB PREFERENCES to File transfer, but its not helping me, the "usb for" option its all grayed out and cant change that.
Right now i'm stuck on a RR build without Gapps, and i lost ROOT and RECOVERY, and as you may think, i cant install any of them because i cant connect to my pc, so i'm in a pretty difficult situation here hehe, could you please help me out?
This helped me. Hope it works for you too

Thanks for your reply, but this didn't work because my device isn't shown on device & printers, or anywhere as far as i checked...
PROBLEM SOLVED.
I think this is the silliest solution I've ever seen, it was just DUST, i clean my USB-C PORT (with a mask xD) and then pluggin, AND VOILA, it worked!!! so keep your ports clean everyone
