[Q] N7000 not recognized by windows.

Hello all,
My mother has a GT-N7000 running complete stock.
It updated something according to ehr saying and afterwards it rebooted.
After the reboot it rebooted again and now its bootlooping, it shows samsung and plays the sound.
The bleu glaze comes up and the the device reboots.
I cant get into recovery with vol up+home+power button combo.
It boots to it and it shows the droid with the sort of cubic icon spinning in its belly and after 3 sec the device reboots.
I cant do a factory reset there so i read about Odin and reflash stock image.
I downloaded the proper file and Odin 3.0.9 and installed samsung drivers.
I dont have Kies installed as i read it could give problems.
The device does go i ndownlaod mode but my PC running w7 ultimate 64bit doesnt recognize the device.
I tried 3 different USB ports from the Mobo, and i tried a couple of diferent USB cables.
One of the cables is original Samung U2 cable.
Everyt time i connect the device winodws shows the message: the USB device isnt recognized.
Odin doesnt register anything so i cant flash a thing with it to restore.
Does this mean the device is bricked?
Does the N7000 has some sort of unbrick JTAG mode or something or would linux help to rewrite all partitions?
Thx for any tips.
With best ergards,
Mister_mini
Edit: thinking back it could be possible USB debuuging has been turned on but im not sure on this part.

How to make phone into varanty-able state (lock bootloader, remove Tampered) w/o PC

Hey guys,
recently i found myself in a sticky situaiton, my USB connection to PC stopped working. Stometimes charging doesn't work until I reboot the phone, random car mode etc...
I tried everything, from reseting my ports on PC, reinstaling drivers, wiping phone cashe, factory reset and so on. PC just says "USB device is not recognized" .
So I wonder how to make the phone varanty possible without USB connection. Maybe trough terminal emulator?. I had TWRP recovery installed and I flashed stock recovery image directly from it, but it's still tampered and I have to get rid of it before taking it to store for varanty.
Any seggestions? I'm pretty desperate, pretty sure it's usb port on the phone or motherboard.

you cannot remove tempered from bootloader and it will show relocked. Its there for a reason, so HTC can see if you been tampering with the phone.
Yes it does void the #warranty.
That said, I send my phone to HTC to replace charging port and they did not charge me .. Have the phone for over 3 years and its rooted.
Tak to HTC but bear in mind Depending the country there's a 50% chance they will charge you.

Note 5 Bricked. Need Help. USB port not working.

I was trying to restore a backup via TWRP, now the Note 5 is stuck in boot screen (over 30 mins).
Can boot into TWRP and Download mode, but my PC (and 4 others running Windows 7/10, Ubuntu) do not recognize the Note 5 showing "Unknown USB Device (Device Descriptor Request Failed)" with the instance ID USB\VID_0000&PID_0002\6&d66f1f7&0&7.
I tried to modify the Android Driver with the corrupted VID & PID, tried to use adb shell etc, but can not see the phone on the PC to try Odin any other recovery process. I tired connecting an OTG flash drive, but can't get TWRP to recognize it.
I have also tried replacing the USB Charging Port of the Note 5, and the same behavior is there with the original and the new charging port chip.
Is there any way I can access the storage, or fix the PID and VID of the phone so I can try to flash firmware via Odin.
All input is greatly appreciated.

usb device not recognized/malfunctioned

keep getting this error when i tried to connect the note 4. I tried updating the driver, uninstalling the drivers, and different versions. Tried different usb cables also and different ports.. Can't odin stock rom because of the error. Phone won't show up in odin. Search google for hours, but not of the solutions I found didn't help. Any suggestion appreciated.
I suppose you download the latest driver for your device. Developer mode has been enable and you are in download mode. Hmmm have you tried different USB ports? What firmware you trying to install? Try different ODIN.

yes, i have downloaded the lastest driver. developer is enabled and in download mode. But in download mode Windows pop up the same device is malfunctioned. I was on firekatv21 rom (android 4.4.4)- which i was lucky to it working from a nand backup. I'm thinking is a problem with the phone. I tried my note 5, and s6+ and it identifies fine. Yes i have tried different ports, and even a different computer. Same issue with the phone. I also tried different version of odin. It just won't recognized the device, however it will still charge thru the usb cables. And yes, i have tried over 7 usb cables, 3 oem samsung cables
Ever get it working? I am having the same problem but with the 6.0.1 stock rom. Tried several cables and replaced the usb port on the device. It also won't work with a micro usb memory stick.

Unfortunately no. I also ordered a new USB port and replaced it so it turns out not to be the USB port. It's either software on the phone or problem with the motherboard. I have tried different pc and windows os, so it's a phone problem. Rules out pc as many solutions online suggested.
Alright, that helps narrow it down, thanks!

Have you had any luck with this issue? I have the exact same problem with my note 4.

[SOLVED] Oneplus 2 Bootloop | USB not working

Hello guys,
Recently I bricked my Oneplus 2 by trying to flash a custom Kernel. That would all be no problem, however my PC doesn't recognize my phone. Tried multiple USB ports (multiple PCs) and got the official oneplus drivers installed, still no connection (tested on Windows and Linux) . That got me believing that my USB port was broken (charging still working), so I replaced the USB module however still not working. (Could it be the cable?)
The current state is that I can boot into recovery (TWRP) and fastboot, however trying to boot normally just shows me the android logo forever.
So well my questions are:
1. What could possible be broken at my phone, that the USB connection is not working. (It worked before)
2. Is there any way to push a rom towards my phone without using a USB connection? So without adb?
Thanks a lot in advance!
EDIT: It was the cable ... I think the data pin broke somehow ... and me stupid as a was replaced the USB module 2 times ... Well transferring CarbonOS right now and will flash real so so thread closed!
