Galaxy Note N8010 - Can't read USB

Hi,
I've had some problems with my N8010 recently. I reset it and am now finding that the laptop won't recognise USB (comes up as malfunctioned).
It's been rooted.
I can enter ODIN by pressing home and power up and can also access download / install customer OS by pressing home and power down (although it just sticks on "downloading").
Thinking it might be the USB (although the tablet was being charged when it was plugged in) I've tried a few but all have the same problem.
I've tried re-installing drivers via device manager, have tried the USB cable connection error in Kies (that goes very quickly through it's analysis and doesn't fix it).
Given I've done a complete re-set there are only the basic apps on the device (other than SuperSU - although I've done a full unroot).
Any other thoughts as I'm stuck and can't fix the issues.?
Settings:
GT-N8013 (although it is GT-N8010)
Android 4.4.2
Kernel - 3.0.101 Boeffla Kernal 3.0-beta6
Build - Gnabo.Rom.v8

Can anyone help?

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.

downgrade samsung galaxy a5 2016 (nougat) without pc

Hi,
I bought Samsung Galaxy A5 (2016), it was running on lollipop as factory, I updated it to marshmallow, then after ca 4 months, updated to nougat.
My phone (that is not rooted) could connnecting to PC (Windows 7), could connecting to other device or to a mouse via OTG cable.
The problem is after updating to nougat, no mouse or other device supported by connecting to it via OTG, and the worst is I can't connect it to PC, bcz I want to downgrade it back to marshmallow.
I use the original usb cable, when I connect it to PC, it shows just charging signal and no notification to check MTP or such things.
I tried to turn on USB debugging, and other usb cable, no successs!
Other device can connect successfully to pc via the same cable and to the same PC.
I could bear everything (no OTG and etc) but connecting to PC is very important, specially since short time WIFI disconnects automatically from device, I tried also many things to fix it but also no luck also after wipe caching data and reset factory, the problem remains also in safe mode.
So many bla bla, sry but any help to flash firmware to SM-A510F (not rooted)...
I think, this would repair everything when I downgrade to marshmallow but without PC, how does it function?!!
