[Q] can't connect to usb debugging - Nexus S Q&A, Help & Troubleshooting

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..

Does it still show that USB debugging is enabled? Are you using the same cable & port on the computer?

[Q] USB debugging won't work in Linux or Windows

Have the usb drivers in windows and it was working. Now it won't turn USB debugging on. I tried on Linux Ubuntu also but no luck. Any idea? I am on custom recovery with stock rom if that helps.
edit: so it appears that that the debugging does work when using adb. adb devices recognizes my s3. But nothing noted in the notification bar when attached via usb, only connected as media device. When I switch to CM10 from stock, the debugging notification appears. Is this a samsung thing? Any thought would be appreciated.
Bump - Had this same issue. Wasted about 2 hours last night trying to figure out how to get USB debugging to turn on so I could start the root/unlock process. Turns out, debugging was on, but the phone never notified me. I'm on a new rom now and it does correctly notify me with debugging on.

[CM12] Nexus 5 is not detected via USB when plugged

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?

G920F, USB MTP, FASTBOOT not working anymore.

Hi all,
So I have a strange problem, a while back I discovered that I can't connect my S6 to my computer and or other computers, whatever usb cable I use the device is not detected at all. and only charging works.
I already tried more USB cables and validated they work with other devices, I also discovered the USB is not detected in fastboot mode, so I can't flash any images anymore over USB.
I also discovered that I might have flashed a wrong stock rom a few months back and I never tried to connect it to the USB in the meanwhile, when I trace the baseband version it says it's Asian..:crying: And this device is a dutch PHN. The device has ADB working over WIFI and root enabled, it also has TWRP installed and even there MTP is not working!
However i'm afraid there is no way I can flash a stock rom back to the device without a working fastboot, unless there are flashable zips.
What do you guys think?
- MTP does not work
- Fastboot works but USB is not detected (odin, device manager etc).. with all kinds of cables.
- ADB Shell + Root Works (Only over wifi)
- I got a full backup of all partitons, created it with TWRP.
- It's stull running android 5.1.1
Best Regards,
Toetje

I can´t belive it, someone who has the same problem then me. A little wierd is that I got 2 phones here.... Got my S6 which I´m using atm and some days ago a friend gave me a A5. Actually the A5 has exactly the same problem and one more problem is, that the "Home Button" of the phone is not working. No chance to root it at all.
It was like this.... I came back home with the A5 and first I thought about was rooting it. Restarted and tryed to go into "Recovery Mode" which wasn´t working, same as going into "Download Mode". So my first thought was that some of the buttons arn´t working. I was right, it was the home button which is without any function. My next idea was rooting over Laptop with Odin. Enabled USB Debbuging, connected a data cable..... and usb connection was not working... only charging!
After like a minute of trying and no success I wen´t eat first. When I came back i tryed again and USB Debbuging asked me to accept the Laptop. (Till now I didn´t thought about that it could be my first and my last time I will have a working USB connection.)
I wen´t into "Recovery Mode" thought about restarting cuz I wanted to go into "Download Mode". So I restarted and that was FATAL.... since then I had no chance anymore till yet to get a working USB connection. No matter which PC, Laptop, USB / Data-Cabel. And since the "Home Button" is not working, I don´t even know how to get Root.
Right now I´m asking myself if it could be a Firmware related problem?! I mean, when my friend gave me the phone there wasn´t the newest update installed on it so I just updated it. It´s a A500FU running stock Android 6.0.1 newest DBT Firmware..... and also I´m not able to change it without having a working USB connection.

I ordered a new USB port board, will let you know the results!
Any results after changing the usb port?
Did fast charge still work for you? And this replacing the USB port work? I think this is related to a broken USB ic. For me replacing the USB port didn't help
Sometimes it's a bad charging port and / or liquid damage to the charging port.
If your home button clicks but does not work it could be liquid damage near the home button. Same goes for power and volume buttons.
I just fixed a S6 edge plus yesterday power button not working, liquid damage all around power button area, fixed burnt components and corroded pins.
