[Q] No USB connection while booted into Android or TWRP...

Hi Guys,
I've had a few problems with my N5 recently...
If I plug my N5 into my PC via the stock USB cable and boot into the Bootloader (PWR+VOLDN) then it will allow me to flash the original N5 firmware, located here: https://developers.google.com/android/nexus/images, this would indicate to me that there is no issue with the actual devices ability to transfer files via USB connection... Right?
No!
For some strange reason my phone will allow me to push a full factory image to it and will also process any Fastboot commands that are sent to it but as soon as you boot into something like TWRP and try to control the phone's ADB functionality it will not find the device at all! The new MTP option in TWRP 2.8 will allow my computer to see my phone's MTP connection for about 1 second and then will immediately disconnect, the same happens when trying to connect to MTP from within Android too.
USB debugging doesn't show that it is connected when my phone is plugged into my PC and Windows makes the 'device connected' sound and then straight after makes the 'device disconnected' sound...
Any ideas? I am certain that this is an issue with my handset's hardware or software rather than any of the computers or cables... I have tried 3 different cables (including the stock cable) and also three different computers (Windows 8.1 @ Work, Mac OS X @ Work and my own personal PC running Windows 8.1 & Ubuntu @ Home)... All OSs and all computers run into exactly the same issue, device connects briefly and then disconnects.
I have troubleshooted issues relating to the driver. This is not the issue... Device Manager cannot even see the hardware after the disconnect.
Thanks for any help in advance,
Lewis
Also:
-Android does not detect that the USB is charging the device unless the device is booted with the cable attached (if it's not attached before the 'Google' screen then it can't see the USB input at all, within android or TWRP, of course...).

It's most likely a driver issue.

Not a driver issue.
3 different Nexus 5s, 5 different workstations. Other two Nexi are fine on all 5 PC's.
1 PC used for ADB forensics, 2 used for ADB development work, one known working for ROM'ing / rooting.
Phone has been factory reset, factory ROM'd from Fastboot. Connects fine on Fastboot. Will not connect on ADB / MTP.
On a fresh PC / phone reboot, the PC will detect the phone for just a second and then it will not reconnect until process is completed.

i used different cables and pcs but still not recognised
yesterday i used odin with those options :
BL/AP/CP/CSC and checked
Auto-reboot
F.reset Time
phone EFS Clear
Phone bootloader update
it has taking some while to execute but after that my phone was working and detectable again by my pc the problem was resolved for a couple of hours, in the evening the problem occured again.
and i have tried the process again the same why but no connection at all.
i don't know if its a hardware problem or software related problem
because the usb work when i m in restore mode (Odin mode) otherwise no.
Its an advance problem i already check all about usb / cable and pcs related problem.

Problem resolved
I sent my S6 to Samsung SAV it take them 4 days.
they doesn't give me proper answers on what they have done but i saw that my mini-usb plug is new so i expect that they got this part changed accrodingly the samsung has no sign of damage its a clean operation.
Its now detectable. It was indeed a Hardware problem

i have the same issue but in a g928f
today i changer my lcd with the micro usb flex
so all is new except the main board and still is not recognised at any pc with any cable.
i am really starting to feel very sorry for this phone.
odin does not see it at all even at download mode.
i don't know what else to do.

Software or Hardware Issue
I have a s6 920t that I am suppose to pay for at the end of the day. I got it from a friend who bought it while overseas. The only time my computer detects it is in download mode/odin mode, I hear the sound and I see it as "Added". When I try to connect any other way I don't hear the sound my laptop makes when it has detected a new device also otg cables don't work. I just simply want to know if this a software or a hardware issue? Software I can fix but if it is hardware I don't want to waste my money. Please anyone reply as soon as you can so I can decide what to do.
Thank you

I have two S6 Edge and one of them started doing this (phone only appears on USB when in Download mode). When swapping the motherboard between the phones, it works. So the problem isn't with the motherboard, but the USB connection module attached with the ribbon cable... There must be a chip on the module which gets locked somehow and replacing the board is at least one way to fix it. Hopefully someone finds another method without replacing the charger board?

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.

Question USB Connection Issues

Brief: Having issues with USB in Windows 11 and my Le2115. Right now, Windows sees the device, and adb devices returns a serial number (with debugging on); however, the phone is not seeing that it is plugged in at all. It is not charging, no transfer options, nothing.
History: So, it all starting sometime after trying to get rid of OS13 and returning to stock, I bricked my phone pretty good. Ended up using MSM and loaded an india version, went back to a Global version, lost touchscreen after updating to v12, used MSM to go back to a different rom (OS-11.2.4.4.LE25AA... don't remember the previous ones) and then updated to C65.
After rebooting to C65, I plugged by phone it that I got no response from either Windows 11 or from my phone. Swapped cables, swapped ports, rebooting both devices, uninstalled Oneplus drivers, rebooted and reinstalled them... nothing worked. Plugged in my LG V60 and Windows would see it fine. Put the phone into Recovery and tested with fastboot devices and the phone showed up fine. Reset the phone to factory... no change; Window would not need see it.
Reflashed the phone to the OS-11.2.4.4.LE25AA ROM via MSM. Booted up the first time and Windows saw the phone just fine and the phone gave me the connection type notification and began charging. Successfully tested file transfer and adb devices. Ran the first update... tested it and everything worked fine. Turned on Debugging to make sure that adb and fastboot worked... they did. Ran the C48 OTA update.
After rebooting, when I plugged in the USB-C Warp cable, Windows defects the phone as an MTP device (sm8350-mtp in device manager), but the phone did not see that it was plugged in (no charging, no notification). Turning on Default USB Configuration allows me to change it to other modes when plugging it in (File Transfer will even let me browse the phone via Explorer), and the phone will show in device manager as a Oneplus 9 G5, but the phone never indicates that it is plugged in and will not charge at all. Plugging the phone into a USB 2 or 3 port seems to do the same thing. Fastboot in recovery works fine. Turning of Default USB Configuration causes it to either detect as a generic USB Composite Device or as an MTP device (not sure how/when/what causes it to change). Charging and warp charging on a power brick works fine and it does show up in the phone.
Seems I am going in circles now and not sure how to get out of this cycle. Any suggestions would be most appreciated!

[TMO To Global] [No Dual-SIM Bug]
Requirements:- * Unlock Token * T-Mobile MSM Tool * OOS 11.2.10.10 and OOS 12 C.48 Global * Fastboot Enhance Instructions:- 1) MSM back to TMobile OOS11 and unlock bootloader through unlock token 2) Extract the payload file from...

That will basically fix your problem. Just use le2115aa
