Usb not recognised when connecting to computer - Ascend Mate 7 Q&A, Help & Troubleshooting

Please help me out somebody. Whenever I connect my mate 7 with pc, it shows usb not recognised. Some info :
1. All drivers are fine . Nothing wrong in pc
2. Tried usb debugging on off but no effect.
3. Factory reset the phone. No effect. Currently I am on 4.4..4 firmware with cwm recovery installed.
4. I also got replaced its charging dock port but then also it is no working.
5. Changed usb cable too . no effect.
6. Actually I want to update my phone to 5.0 or 6.0 but for I should be on stock recovery which can only be flashed in fastboot mode . But as usb is not working cant flash it in fastboot mode.
So please tell me is there any way to flash stock recovery without using usb cable ?
Or any otherway I can update my phone to lollipop or marshmallow over kitkat without stock recovery and data cable ?

"unknown usb device descriptor failed"

Did your phone charge at very slow rate with official data cable ?
Have you got your battery got replaced since you have buyed the phone ?

The next big thing happened to me is one day it got off suddenly and after that it nvr got on. On charging only the red battery logo comes with red led blinking and nothing happens even if i leave it charging for whole day.
Then i by passed battery and then connected cable then boot animation comes for a second.
So i doubt it might be faulty battery in our case or a typical hardware issue.
Actually this phone was not released in my country so i have ordered battery and it is arriving within 2 days. And you have btter chance to get the phone rectified by huawei. Also ask them what was the fault , it might help me if battery did not works.

USB connecting problem.

Hello guys!
I have been using my 1+1 since september. Everything was allright! I have changed rom and kernel many times, so it means that i have got my ADB installed and know something about tweaking a phone. I say that, becouse last time i asked for a help, i heard only simple solutions. I already tried them all.
So, my problem is:
When i connect my phone to PC 1+1 start to charge, but PC can`t see him. I have tryed it on 4 different pc (all windows 8 or 8,1 (64)) and 2 different cables (native and my old one). All PC can`t even find 1+1 in device manager. Ofcourse i have confirmed USB-debugging, MTP etc. This problem suddenly appeared without a reason.
So i used native reset function and now my phone got no Root and Recovery. I don`t know what to do. Any ideas?
Any help. guys?
Still need help
Did you update your SDK?
If you're using the original USB cable that came with the phone try swapping it with a non-OPO cable.

test with another PC?
Two other OPO users had similar issues and it turned out to be the original cable. That is why I'm suggesting a different cable.
I have used another cable and 3 different PC. Still cant find my phone!
updated SDK but it didnt help
Weird. Try uninstall all driver. Then re-install back OPO driver. I think that is not cable issue since you have tried different pc and cable. Hmmm really weird.

@xanthrax need your help on this. Really weird problem. What do you think?
Just need your experience
i`m a bit confuse here
on the first post he says " after reset , no root no recovery"
what`s the status now ?
try pdanet app, it comes with universal adb drivers
i already installed reinstalled uninstalled drivers. i hae tryed all manipulations with drivers
etm my phone has no recovery or root, beacouse i did factory reset (thought it might help). so i cant install another rom (beacouse cant use abd fastboot or recovery)
any other ideas??
maybe its problem with phone usb port
Did you try like what xanthrax said? Try it first then let us know it help or not.
Weird. Charge can detected but not showed up on your pc. Hmm

PC doesn't recognize my Note 5 N920P

I'm having this issue with a Note 5 from Sprint, it charges well and OTG functions as well, but my pc only recognizes on Odin when it's on download mode, help please. It has root and twrp recovery, android 5.1.1. I've already tried the *#080# to change to MTP but it saids invalid MMI.
You could try powering off your note5 and then plugging it into your pc with it powered off. Then boot into recovery and your pc should give you a prompt that it will try to install the correct drivers. Not a 100% sure it will work but you can try it. Also what drivers did you download and install for your note 5 to be recognized by your pc? You could try theese if you haven't fixed your issue yet. Hope this helps.

I tried with the ones on the Samsung official webpage, now I flashed a stock rom and still doesn't works, plus now the LED won't turn on and it rings only when I have an incomming call, but no when receiving a sms, or aney type of notifications. I'm so frustrated
What kind of pc do you have and what os are you running?

When you plug your note 5 into your pc what does it display in device manger?
Nothing, nothing pops up, not evern a message saying that drivers couldn't be installed. Thanks for your help, I ended up selling it
Had same issue and would also not fast charge. MTP not being recognised and had to have Sprint replace it. Charge was $75 because I had no insurance but a complaint to Sprint that Samsung would not fix issue that was replicated by Sprint store allowed me to get a $75 credit on account, so a wash. Worth a shot.

Also, FYI i did send it back to Samsung to repair BUT they do not have the actual issue available in their issues dropdown area so they just put issue as "would not recognized charger" Well when repair received device they tested, saw it started to charge and just send it back out without fixing anything. Very frustrating but all worked out with device replacement.

my phone doesnt recognized by pc if i start downloading mode

Hi guys .
i flashed "by mistake " the wrong cwm recovery by ( Rsher ) . after the device is restarted the screen just stopped on welcome screen .
now i have no access to recovery mode .
so i tried the other choice which was the download mode .

"usb is not recognized . the last device you connected to computer malfunctioned and windows does not recognized it "
also odin does not recognize it .

** my phone is galaxy s II Plus working on android 4.2.2
**my pc is HP working on windows 10
**i have the latest Samsung kies and the latest drivers
** what i have tried
*update the driver on my pc
*uninstall and reinstall the driver
*using different usb cables
*uninstall the drivers and restarting pc
*updating other generic usb hub
*changing values in the registry
*I have tried all versions of odin
*pull the battery and entering download mode several times
PLEAAAAAAASE HELP :crying::crying::crying: ​
Try installing the google USB drivers.They are normally installed with the android SDK. Maybe they can help you detect the phone or you can try to manually update the driver.

as i mentioned above sir , the phone is recognized when it is ON but the problem occurs when i go to download mode . i think it is not concerned with the drivers
Have a look at this soft-brick help guide. If your phone is not even able to enter the Recovery Mode, you may have a case of NAND rw corruption and recovery may not even be possible (you may have to look at hard unbrick scenarios).
Having said that, these are a few things I might have still tried if I were you:
1. If you have access to a Linux PC or a bootable Ubuntu drive, start it and see whether it recognizes your phone using the lsusb command. It will help you to rule out any driver issues.
2. Try to drain the battery (by keeping a long time in that welcome screen) and then do a fresh recharge and then try again.

Samsung galaxy note edge (sm-n915f) super bricked - need help urgent

Hi Guys,
For unknown reasons my fone went DEAD (BLACK SCREEN... NOT A SINGLE SIGN ON CHARGING OR USB).. Need advice what to do ??? is it dead or can be brought back to life by FLASHING ???
Any senior member or someone please help me ...
If you connect to pc how will it be?try charge it first.then connect to pc.if detect, flash stock rom.if cant,try find spare battery just in case.
FOne is not showing any charge sign or anything... just QD LOADER 9008 in Device Manager
Do you see charging light when you plug in the charger?
As long as the phone receiving power you can fix it.

Try connect to kies.does it detect or not? if you able to flash. try flash it to 5.0.1
What was the battery level (approx.)when the phone died?
You might want to try cleaning the battery and internal phone contacts with some Isopropyl Alcohol and a Qtip.
See if that helps.

No Sir still no solution of this problem
I helped a good man, he sent an image of the device. I recorded this image of the sdcard and the device will start with "Download" mode. Next, it is necessary to firmware flashing.
915F - sorry - region "SER". But the main thing - is to run the device, further will flashing firmware what you need.
Site do not give insert a link to a file. Write me in the mail - "[email protected]" I'll send a link to file/
Write the file need with program "win32 disk imager". If this method does not help is probably a problem with the hardware.
Good luck.
As per the screen shot posted it seems your pc picked up the correct driver. Now all you need to install is Odin. Then go to samobile.com and search your phone under Firmware. Make sure you got the exact model (pull out the battery and look for exact model #). Once downloaded go to Odin and check AP and select the file you downloaded. Then put your phone on Download Mode by pressing Vol Up + PWR at same time. Follow the instructions on your phone screen.
Once you connect your phone to pc it will show up as Port 3 or 4 or wherever the driver is connected to.
** As long as on Odin your phone gets picked up you will be able to push the firmware. Once you can do that you pretty much fixed it. If it's wtong fw then you will get a notice right away, if it's correct then you see the progress bar changing.
BL is corrupted, need to repair it,
Since this is a Qualcomm based device, you can flash only BL files to an SD Card then boot your device from that card until you get into Download mode,
then reflash the device with Odin,
Follow this guide:
1. Download debrick (BL) file from HERE,
2. Download Win32DiskImager from HERE,
3. Get an 32GB SD Card and connect it to PC,
4. Setup Win32 and Run it then do as the following picture,
5. Just let it finish, Then disconnect the SD Card,
6. Make sure the device's battery is well charged,
7. Put the SD Card into the phone,
8. Now you need to boot device into Download mode either by using USB JIG or by holding (Vol-, Home and Power),
9. Once device boot into Download, Pull out the SD,
10. Now just flash the phone with Latest FW (either Factory or One-Package will do the job),
11. There is no 11, we're done ..
##NOTE: Solution is TESTED and it works.
@mirosaw2 Will this also work with the SM-N915FY? Will this keep my data (contacts, SMS, photos etc) on the internal storage? I have my SM-N915FY in a state where it wouldn't recognize any commands, but it makes a connect / disconnect sound on my Windows computer when I just connect it via USB...
My original question is here.... https://forum.xda-developers.com/note-edge/help/note-edge-sm-n915fy-bricked-dreadful-t3754559
Edit: I just tried it and it worked!!! Thank you very much, now I'm able to restore my data and then I'll try to make the error gone with this tutorial: https://forum.xda-developers.com/showpost.php?p=66879466&postcount=10

What version of Odin do you try?
And try another port + cable.
odin 3.10.7& 3.09.3
I am having this same problem with my S6 920i today, it is giving code 43 device descriptor request failed in fastboot(odin), recovery and when booted up.
Also it draining battery very quick and getting very hot. I think it's software but I can't solve that while the USB is not working like this.
I used the USB yesterday to transfer files.
try dialing *#0808# and set usb for different modes there and see if that helps.

The getting hot/battery drain was from the Oculus update that was constantly trying to install another update and failing, it affected everyone with a GearVR that had been used on phones at any point.
My guess is that the extreme heat damaged my USB controller chip. The phone already has the sensor chip not working which disables everything from GPS to rotation to the heartbeat sensor and even the proximity sensor. Life has sucked for me with this phone.
