today i made a very stupid mistake while i tried to root my S7 edge.
I put the phone to Download mode and installed twrp-3.0.2-4-hero2lte.img through Odin FIRST,
before installing CF-Auto-Root-hero2lte-hero2ltexx-smg935f.tar
It was a really careless mistake, really stupid..
what happens now is that the twrp is not installed (cant load into the twrp recovery). and it is stucked at the samsung s7 edge screen.
the phone can still boot into Download mode, but my computer cannot detect the device anymore.
it only recognises the phone as "unknown usb device (device descriptor request failed)"
- i tried with 3 computers (all running windows 10), 3 different cables, all wont work.
- battery has been fully dead and then re-powered on
can anyone help me with this please? i will donate to your paypal if you can help me fix this problem............
Have you tried to switch the cable / usb port and use the emergency recovery on the Smart Switch software?

Hi there !!!,windows doesn't recognize my s4 i337m in download mode (code 29), when i was flashing (stock canada 5.0.2) my cousin unplugged the cable by mistake, now i can go into download mode but widows 7 doesnt recognize anymore (tried different pcs and cables , the same), did it damage the usb port? or is hardbricked?? what can i do??? please help!!
I'm no expert on this, but you can try taking out battery. Hold power button to discharge hardware and put battery back in and see if it works. You can also try factory reset & wipe cache from recovery (Vol Up + Home + Power) and try again.
Your phone at least goes to Download mode so that's good sign I guess. You're using ODIN to flash 5.0.2, right?
Wait more experienced person to answer, though.

Thanks bro, but i did what u said and it's still not working, the problem here is that windows does not recognize my s4 (usb port: unknown device, code 29) , yes i'm using odin to flash, but i can't flash until my device be recognized, that's why i need to know if my device's usb port is damaged?

It looks like the PC does recognize something is connected; it just doesn't know what the device is. This makes me think USB port is fine otherwise PC wouldn't recognize anything AT ALL. Does the phone still charge?
You can try the 3 methods here. I know it says for Code 28, but it will reinstall drivers for usb ports. Restart and see if phone is detected.
If it's still not detected, remove Samsung drivers, Kies, or anything related to Samsung phone. Restart and install Samsung USB drivers again. Restart again and see if phone is detected.
bro i'm afraid it did not work, perhaps replacing usb port on my device? or the whole flex?
aditional data: my nephew unplugged the usb cable by mistake while i was flashing canada stock 5.0.2 , obviously odin "failed" , but after that , windows 7 does not recognize my device anymore. i can still go into download mode.

Well, I'm stumped too now, man. You can try the driver thing I said on another computer. I don't know any other things you can try.
If you can charge your phone, your usb port probably works fine. The firmware got corrupted, causing this problem most likely.
solved!!

bro, my friend flexed it with medusa box for 20 dollars, my phone is fully functional now!! anyway thank u so much.
Hey!
New to XDA but a complete fan of the help and guides you guys provide.
So, I acquired an i9060 smartphone and successfully installed CM 11 without the help of my laptop since the usb cable through Odin never worked for me (driver issues on Win10?).
Unfortunately, my phone entered an Android boot loop. And now with a lot of attempt I can't even enter CWM or even charge my smart phone, as it always reboots while trying to charge the battery (it's always drained) or gets stuck during logo before accessing CWM.
I tried to install Samsung drivers, Kies, ABD, Odin to restore the firmware but... nothing seems to recognise this Samsung device. Does anyone had the same problems I'm having now? Any suggestions?
You might try another USB cable, USB port, or even another computer. Without Odin, you're not going to be able to fix this since recovery is no longer available.

Tried on 3 laptops but the problem persists. Never thought of changing my usb cable though. I'll give it a shot
Btw, is there anyway to use an external SD card to force a factory reset?

Have you considered the possibility that your power button is sticking? Not the part that you touch but the hardware switch behind it?
Do you have USB debugging enabled?
Are you using the stock cable or at least a USB cable with the same number of pins/pinouts?
Hello guys,
after trying everything I could imagine and find on the net, I still didn't get my PC to recognize my S6 edge plus.
Hopefully someone od you has got some more ideas.
The Problem:
Connected Phone shows "Unknown USB Device (Device Descriptor Request Failed)" in the device manager. No MTP connection and no ADB possible so far.
Done so far:
Samsung USB Mobile Drivers
Kies
Smart Switch (with reinstall of drivers)
6 different cables with 4 PCs (2 Win10, 1 Win7, 1 Linux)
USB-Debugging on / off
*#0808# switched through every mode
USB-Hub drivers
Factory Reset
More Info:
5 of the 6 cables are working just fine for data connection with my S3
There is no infobar tooltip to change USB mode at all, just telling me it's loading
In Download Mode the phone doesn't get recognized by Odin (with same cord and USB Port the S3 does)
In Stock Recovery Sideload Mode the Device does not show up in adb devices (with same cord and USB Port the S3 does)
Regards
up
I'm guessing you have downloaded and installed the Samsung drivers?
New Infos on this case:
Local tech support inspected the phone. They suspect the mainboard to be defective due to corrosion signs.
Of course the repair cost would be ridiculous.
I'm gonna repair it myself, but I'm not quite sure if it's really a faulty mainboard.
I rather think of changing the USB board first, because it's like a 10th of the mainboard and more likely to get wet if that's the reason for the damaged phone.
Any ideas??
Regards
You didn't mention if it charges via USB?
Im in the same situation..
charge via usb but is not able to recognize the phone in any computer (a lot of different cables with 3 PCs)
My unit was wet and i think that something is wrong for this reason.

Hi Cento50. Have You managed to get the phone to work? At first my phone was showing up in "This PC" on Win 10. but after trying Samsung usb drivers to get Odin3 working now it is the same as Yours. Shows in Device Manager as: Unknown USB Device (Device Descriptor Request Failed). A strange Conundrum.
Hello @Photobil2012 yes fix habe worked!
One little wire have replaced 2ohm resistor.
And have fix fast charger and data comunication with PC!
We i have repaced first one diode.
Phone a this time work complete.
First this problem i have connected one hard disk to otg cable with phone battery low!
My suggestion Please caution to use otg interface with high current if have low battery in the phone.
This cause high current drain and possibile burn diode and resistor.
Hi Cento50,
Alright! Thank you very much for the most timely reply and tech info on the successful fix. This is very good news to receive. I just replaced the battery so it is brand new and that works fine now. However, if it is necessary I can apply the same type of fix that you applied. Great work, and thanks again for your help.

1. Are you able to enter the recovery menu?
2. Are you able to enter the download mode?
3. Do you hear the USB connected sound on your Windows machine when you connect the phone while the phone is in download mode?
4. Have you tried different versions of Odin? During my researches I have found a site which recommends 3 different versions to try (AndroidSage: Download Latest Odin 3.13.1, 3.12.10, 3.12.5 Tool For All Samsung Galaxy Devices).
5. Have you tried installing a custom OS again or the stock Samsung OS?
1. unfortunately not
2.yes, this works fine
3.no
4.I tried just 3.14.4
5.I am trying installing stock firmware

I assume that you know that there is a warning before entering the download mode which you get rid of by pressing the volume up button.
Are you sure you are using a USB data cable and not only a cable used for charging? The first one usually has 4+ wires and the second one only 2.
If you are sure that you are using data cable then you can try doing different stuff to your phone (like turning it on and off, entering download mode and exiting) while connected to the PC and listening if any sound comes out of your PC.
Hi,
I tried flashing the new v11 firmware via Odin. Unfortunately, i didnt work (i come from v10). Now i get that error message , that i´d have to use Smart Switch soft on PC to do an emergency recovery. Unfortunately it seems to find it (some usb plug in sounds appears in windows) but the device can´t be found. Whats the take here ?
The USB drivers seem to be installed fine. Thanks in advantage!
