I have been trying to connect my note 4 to a computer to flash a stock rom (via odin and fastboot). I tried three different computers, with 4 different cables. I finally gave up. It continuously gave me a non-descriptor error that doesn't seem to be fixable. I decided that the USB itself might be damaged. I tried running the latest version of Mobile Odin but that softbricked my phone. It is now in a permanent boot-loop and I can't access any recovery. Is there a way to boot in to a recovery via the external sd card? Is there a fix for the USB error (Unknown USB Device (Device Descriptor Request Failed).
I am not a rich man but I am willing to donate via paypal 5.50 (so you get 5 bucks after taxes), if it's fixed.

I lost recovery on my phone and when I try and boot my phone, it says "system software not authorized by att."
I'm trying to ODIN my phone back to stock but I can't see my phone when I open ODIN and put my phone in download mode. does anyone know of any fixes for this?
Try different USB port or different cable.
You might have to try a different computer. I can't for the life of me get my pc to recognize my device. But I have no problem on my laptop

Thanks guys. I found out that I had to restart my computer after installing the drivers and then it detected it with no problems!
I need some help guys.
My Nexus 7 all of a sudden stopped sending data through usb OTG and i tried to erase cache through TRWP but ended up deleting the OS. Now I am stuck with a device with no OS. I cannot mount the USB for my computer to recognise it so that I can restore it. I tried ADB sideload but it doesnt load and gets stuck on starting...
If I click on Mount, I cannot click on the USB-OTG box. My computer does have the correct drivers for the USB as it used to work on it before but since the OTG stopped responding to data I am now stuck and cannot push a restore image to the device.
Any help would really be appreciated.
Many thanks.
I've tried almost everything I can think off. I tried different OTG cables, different computers. None of the computers even detect a device as plugged in. Whether I boot into bootloader or recovery I just cannot get the PC to even acknowledge the fact that something is plugged in. As a result I am just not able to flash it at all. I tried NRT with the soft-brick option but that fails too because it says no adb connectivity.
any help please?
Hi All
I am looking for an update.zip file I can use to flash the stock 6.0.1 rom again over my existing version to fix a USB connection issue. I need a Samsung OTA update.zip which can be flashed from the stock recovery via an sd card.
This has come to light as I've recently tried to update my note 4 to nougat but came across an issue where the phone will not connect with my PC via USB. I have tried all the usual tricks on the phone (dev options, usb debugging, MTP+ADB etc) but nothing was working. In the end I have replaced the micro usb daughter board on the phone thinking there must be an issue with the data pins but the phone still refuses to connect but charges fine. Strangely the phone thinks it's connected fine but the PC says it is not getting a device descriptor response. I have checked drivers etc and also tried 3 other PCs all of which connect to my old S4 without issue. I have also tried various USB cables including a new genuine samsung one.
Due to not being able to connect to a PC in any mode (such as odin download mode or recovery) and having the stock recovery without root my only hope is that a new update.zip will sort out corruption from the last OTA update. I believe this may be the reason as I was able to connect fine until the most recent update a couple of weeks ago. I have tried using a zip from the samfirm downloader but the recovery failed immediately with 'unable to map file'
Any help you guys can give would be greatly appreciated as I really don't want to be stuck on Marshmallow now Samsung will no longer be updating the Note 4.
I have tried connecting in MTP mode, odin download and recovery mode with usb debug both on and off
Many Thanks

Have a note 4 on a custom rom- android kitkat. Was working fine, until i wiped data/cache a few times in TWRP recovery to do a clean install of the rom. Phone restarted without an OS, and then i couldn't get pass the boot logo screen. Couldn't flash any rom in recovery. So i did a restore thru TWRP from a backup. So now the phone boots, but it pc won't recognize it. Everytime i plug it, I get "One of the USB devices attached to your computer has malfunctioned, and Windows does not recognize it". Under device manager, I get "Unknown USB Device (device descriptor request failed)".
Things I have tried:
-Uninstalled usb drivers and let windows reinstall,
-at least 5 different usb cables
-at least 3 different Samsung oem usb cables
-other usb ports on the PC
-3 different pc (all with same- so im guessing its a problem with the phone)
-physically tried to push up the usb port on the phone- bad connection (someone recommended on google search)
- even when as far to reinstall windows OS
-*#0808# and set it to AP, MTP + ADB
-yes usb debugging is enabled
-download mode (odin does not see the phone, so cannot flash stock/custom rom
-diferent versions of odin
-different version of Samsung usb drivers
-have other samsung phones (note 5, and s6) and windows recognize those.
-phone does charge thru usb
need to get phone working again

Download stock rom from sammobile and flash it via odin.
Or else, flash the cf auto root file via odin, this reset all partitions.

Sorry, my bad.
So, the author can try to repair partitions via twrp.
Go to wipe/advanced wipe and then select "Repair or change file system".
Select the partitions and repair them.

Honestly man search my username ziggsta2 I had the same issue I had to buy another note 4 and even this used phone I got off eBay has the same problem when I wiggled the micro USB cord up and down I got it to connect, I don't suggest you doing this, but what might work is taking a very small piece of plastic and cleaning out your USB port on your phone, I believe these ports go bad after awhile as I have encountered this twice on two separate devices maybe you have a different issue but theres my two cents

i have tried. at this point i think it's hardware failure with the usb port. Stupid buying those cheap usb cables probably damaged the port because it seems to require a little more force than samsung cable. Planning ordering one and replacing. hopefully i don't do more damage. Had this phone for a long time and miss flashing roms on it.
i have still not fixed this problem....lol. had a new phone and been in drawer. did replace the usb port but it wasn't the problem. would like some solutions if anyone can help.

You need to install the Samsung USB drivers first.
Have you tried restoring your TWRP backup?
