Could not get USB Debug mode for Verizon.

Hi,
I have a hobby to develop phone application.
I have no problem with connecting my HTC phone to my laptop for "USB Debugging connection" but my Verizon Samsung Galaxy s3 SCH-I535 could not get the "USB Debugging mode".
I DID CHECK the "USB Debugging mode in the system menu" however, my development environment could not get the debug mode.
Actually, when I plug in the USB with Galaxy s3, it shows the folder of the phone as usb data storage but not for debugging connection
Is there any way to get debug mode on my phone? Do I need to return this phone and wait for developer version of phone when Samsung launch in the developer site?
Thank you

I had the same issue where the galaxy only wanted to identity itself as a mtp or a camera device even though the usb debugging was enabled. adb devices command return nothing aswell. Found somewhere on stack overflow that installing the samsung kies suite would install the debug driver needed for adb to pick it up and it worked for me in my case, so hopefully that'll solve your issue as well.

I had that problem too, and I found it to be a driver issue. Grab the USB drivers from http://forum.xda-developers.com/showthread.php?t=1756885 (links direct to Samsung's site) and Win7 should detect everything.

I am having the same exact issues on my Sprint S3. I have installed all the drivers. Turned on USB debugging, and nothing! I am about fed up with this. I can transfer music over to the SD card without issue. When i try to put on anything other then media it tells me my device has stopped working or was unplugged. If i wasn't past my 14 days I'd return this thing and go back my Evo.

No MTP connection

Hi, I have a root Galaxy s6 on android 7.0 with TWRP and I can no longer connect it to my pc. I have tried *#0808#, choose MTP in usb debugging. Even TWRP 'mount' do nothing. And the thing is that my USB charging port is not broken because my cellphone work in 'download mode'. If someone could help me I would be very happy.

J7 Prime MTP not detected

my J7 Prime's MTP is not detected at all. it defaults to charging mode only, without any other prompts for USB connection toggles
I tried using my older LG G4 which the MTP is detected.
I'm trying to root my phone (J7 prime). my PC is win 10 on the latest update for anniversary update.
thanks.

I have had same problem. But the reason for it happenning was that there was something wrong with my pc usb ports(though the problems only happens when I have phone connected to it). Restarting pc usually fixes it.
No idea will this help.

Hello
ir i've tried restarting the pc couple of times but no result and also tested on another pc and usb cables.
thinking to visiting customer care centre

did you try to factory reset

udb debugging won't stay on

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.
