Hello guys, has anyone of you had a problem when you connect p8lite to pc. Only charging icon shows up and windows gives error:
Usb device not recognized
One of the USB devices attached to this computer has malfunctioned.
Ver. B564
I tested on my second computer and same problem.
Tested:
Usb debugging on/off
Different usb cable
Different computer
1. What version are you running on huawei?
2. What windows are you running on pcs?
1. B564
2. Both have win10
well .. i have no idea ... i'm also running b565 @ win 10 and i don't have any problems
try factory reset or try to plug in differents usb slots.
I tried different usb slots on both computers (USB2 & USB3) and still same..
I don't think that factory reset would work because it is still unrecognised even i shut down the phone
Would it be possible that phones connectors took some damage while dropping phone from pocket ?
You forgot to mention that
Of course it's possible, the phone could receive a shock which could lead to a short circuit from dropping xD
Is your phone in warranty?
Nope, bootloader unlocked.
Well so i have to learn using phone without adaway
I dunno if with bootloader unlocked your warranty is voided because it's not the same as rooting your phone .
Yeah. But i won't send phone back because usb file transfering isn't must have. That's only sad i cant install TWRP.
Edit: sorry! Read wrong
I know warranty is voided. But while i updated to B564 i lost twrp and now because usb wont work i cant flash it again to root

Unlocked bootloader isn't always voiding your warranty.

recently, i am facing this problem too... don't know how, but everything was fine until a week ago...
Specs:
Build Number : ALE-L21C432B574 Sokkoban's Deodexed ROM
Rooted: Yes
Bootloader Status: Unlocked
Xposed : Yes, v85.1
Same problem here and I think it might have to do with the rooting. since having SU on it usb not been working so only hope maybe is to do factory reset that am going to try and see if works and backup everything first and go from their.
Have tried reset no joy still the same so am guessing something more to do with rom its self as never dropped phone or anything yet usb works now and then maybe hardware no idea but only happend since rooting.
Ok it worked with default cable on my laptop and my friends laptop..

Great phone but for some reason only Chinese logic can explain OGG/USB function on p8 Lite comes factory disabled and even flashing it does not seem to help. NEVER AGAIN, HUAWEI If you cant enable a fkkn standard function on a midrange mobile then you are utterly useless .
I have same problem,,how to fix usb not recognized

Hey guys,
I currently recently installed a custom ROM from this website and for some reason now when I plug in my USB into my PC it comes up not being detected so when I put my phone as hard drive so I want to transfer music, it doesn't detect it. Can anybody help me if this is ROM problem or just my USB?
Hey,
Okay I disabled USB debugging didn't know it was on, still doesn't work says windows cannot find USB device not reconginzed when I connect the USB. For the Reinstalling usb driver I do not know how to this ~?
i have the same problem.. turn "fast boot" off and restart the phone.. this always works for me.. hope this helps
Hey, I turned fastboot off. Doesn't work. I ordered new usb cable.. hopefully this works and it was just a fault with the cable!
Sent from my Desire HD using XDA App
Usually this is a problem with the cable. Simple, cheap to fix. Keep your old cable around for charging though (nice to have a spare)
Is this problem with the USB still active?
If so try a different PC just in order to eliminate WinOS issues.
If not close.
Hi,
I have the same problem at some months ago. I tried the cable and pfone on another PC, and it works fine. So, I recommend to try it on another PC and reinstall your Windows.
brgs,
Herold
Had the same propblem! Turns out it was the usb cable, it charged fine with the cable but data transfer didnt work.
i also had the same problem since last week and still cant resolve till now...i try all the option that u gave(change cable/pc,turn off fastboot)....i even sent my phone to shop and they still cant detect.they said maybe the usb port is damage or some software that may block my usb port?is it true? anyone can help?????

USB BRICK in my INSPIRE 4G ( DESIRE HD)
Hi, all
I got a new inspire 4g last week.( equivalent to desire hd ). It was working fine. But now it does not detect the USB connection. It only charges when I connect to pc. No other issues. I have also noticed that during fast boot mode also pc does not recognize the phone as device. I have tried all the suggestion on xda but no luck.
As fastboot is also not detected by PC I could not format mtd0 and reconfigure it.
Can anybody have any other idea? If I change the main board how much cost will incur ??
Thanks all.

First of all.. you have HTC Sync installed right?
Happened to me initially as well.. although for me changing the cable and/or changing the USB port on the PC solved the issue. Have you tried these?
Also sometimes killing all apps on the device before connecting helped.
You can try accessing your device through ADB to see if its being detected.
And I really dont think you'll need to change the main board..
USB brick on my Inspire 4G
Thanks for your reply. When I go the phone ADB and Fastboot were working
well. There was no driver issue. Now even PC also does not detect the phone or any new hardware when I connect it to pc. I had working fastboot on both win7 and Linux (ubuntu) pc. Now in both OS the phone is not detectable. Windows device manager does not see any new hardware when I connect my inspire . dmesg also does not show my hardware when I connect my inspire to linux pc.
Please help or suggest me to investigate further. I know how to install and work with adb and fastboot as well as Clockwork recovery ( also ext recovery). Some people suggested to flash a new radio. I can flash the new radio via sdcard. But how safe is it ? My phone is S-off and made unbranded. Will flashing a new radio make my phone locked AT&T again? ????
Thanks a lot

As far as I know.. USB problem has no relation whatsoever to Radio. Radio is only concerned with the signal stuff. Flashing it isn't that risky if you follow the instructions... There's a thread in the development section about Radio's which explains it pretty nicely.
As for the USB problem, are you using a Custom ROM? Some ROMs like LeeDroid have USB detection problem which can be solved simply by flashing a different kernel like LordMod's.
What I meant by "Accessing through ADB" was if commands like "adb remount" or any adb command as such are working when your phone is connected to the PC? Or is it showing "error: device not found"?
Sorry for my English I will try to explain my problem.
After rooting everything was fine, but when I try to flash stock firmware somethings happen.First problem is that my PC cannot detect the phone with Odin and adb or mass storage I am 100% sure that the problem are not the drivers because I root that phone on the same PC before a week and of course I try everything on a another computer, but without success.
Download mode Odin cannot detect the phone! after many attempts to fix usb problem now the phone cannot boot , only in recovery (loop)after every start it's show recovery with message
Filesystems:
system: rfs
data: rfs
cashe: rfs
maybe system, data and cache files are erased I don't know.
recovery version is 0.1.3.b5
How can I flash stock firmware without PC. For example HTC devices can flash from SD card - Gold card, and PB99IMG.zip (I can't explain very well what I mean sorry)
Maybe the phone is usb bricked !
working..
recovery - only recovery
Download mode Volume Down + power off + camera ) - but cannot connect to PC and Odin.
not working
after flashing new costume ROM - the same thing - reboot to recovery
installed software on pc
android SDK,Kiesmini_1.0.0.10075_1,Samsung PC studio 1.5.1.10064_2,Drivers for spica on (Windows 7 x86)
really I cant find post like this !!! and sorry for my English
If you can go to download mode and phone is not detected, then you have bad drivers or bad usb in PC. Try another PC.
I have 3 pc and 2 cables and the same problem cannot detect. Can I flash new stock firmware without odin ?

Calm down. Did you read what I posted above? I said nothing about drivers. Have you tried other USB ports? Most people find the ports on the back of the CPU work the best, not ones on the front, or on a hub. It does make a difference.
Hi, background is this..
I have a D802-10C G2 that i rooted the stock 4.2.2 rom a while back using the post chinese method. Easy enough, all worked fine. no complaints. A couple of weeks ago i got offered the OTA 4.4 update, this failed due to the root. I then removed the root using the feature in super su. that seems to have worked as no apps or file managers etc could get root access. However, the OTA still wont work.
Now my problem is my phone will no longer be recognized by any operating system, on multiple computers. I have tried many ADB drivers, Windows 7 wont even detect the device, i've used every PC connect mode, USB debugging. However always the same result, it's as if i'm plugging in a blank usb cable into the computer. Nothing at all.
The only thing that does happen when i connect the phone to a computer is the phone starts to trickle charge. There is nothing detected in Device Manager in Windows 7 I've tried connecting in download mode, nothing. I've tried the LG support tool, PC sync. Nothing.
WiFi does connect to the PC suite fine BTW and other than that the phone is working perfectly. I've also tried connecting multiple usb cables on multiple ports.
I haven't been able to find a single case of the same problem in the week or so i've been looking. Hoping someone can help, i'm thinking i may have soft bricked my phone. I really do not think this is a driver issue.
Any help would be great. cheers

YOu can try checking the device manager or use other USB port on your phone.

The problem is not like the usual ones you will see about "computer not being able to see device" I don't think it's a driver or software issue, or if it is it's unlike any i have found in the weeks i've been searching the net for a solution. Here's why....
When i connect the phone to Windows 7 and 8 ( on 3 different computers) No hardware is detected, nothing in the Device Manager, no yellow question marks indicating 'Unknown Hardware'. Nothing, all it does is start trickle charging.
Now even with no ADB, or any driver at all installed, the computer should still detect the phone. Mine does not.
The same thing happens using OSX and Linux Mint 16 (again multiple computers) No devices or mounted or volumes shown at all. Linux terminal command "$ lsusb" does not list my hardware.
This is why i'm pretty much convinced that there is something wrong with the USB port on the phone. Because, if Linux can't see it then surely it's a hardware problem right?
The only other thing i can think of is, i have messed up the phones firmware while trying to unroot it? but only because the timing of all this is just too uncanny.
I think i'll have to suck it up and admit defeat here. Funny thing is the phone works perfectly and charges fine.
Stuck on 4.2 , with no ADB functionality. Perhaps i'll sell it cheap to someone who doesn't care.
Cheers for the reply mate.
Same problem here!
Only my G2 is not rooted, it is still on factory OS and recently updated to 4.4.2.
I have tried on several computers, different ports and no help.
On the first connection to a PC not connected before windows reports "USB device not recognized" problem.
After that every time I connect the phone to the same computer the phone itself only recognizes that it is using USB charging mode, it does not recognize the computer connection (known by the USB ison on android system tray) even with "Ask upon connection option checked".
Even when I manualy change the Android mode in Settings --> PC Connection from MTP to PTP or even LG software, nothing happens.
Definetly there seems to be a problem with the phone, but I don't beleive it's a software but a firmware problem.
Please help if anyone knows what to do.
same thing happened after installing T-mobile rom thrugh twrp. but my device boots into fastboot and i tryed falshing :
laf.img, boot.img, aboot.img, recovery.img, laf.img
but after reboot my LS980 dissapear from device manager and stucked on LG logo.
Dont know what to do now.
I'm no expert, but given there are a lot of them here and none have weighed in on this with any ideas for a fix, i'm going to assume it's a hardware problem.
Anyone else agree? Hardware problem not software?
Cheers
I guess that you already wiped everything right? Apart from that, i'll suggest you to go to some tech supp and ask them if they can verify that each pin of the micro usb is properly working.
Sorry for my english, hope it helps!

I will try to check the connector although i dont think that it is a hardware issue.
BTW I can enter the download mode after flashing the mentioned partitions and i can also enter the stock LG recovery but when i do the factory reset it keeps showing Factory reset processing ... for ever
It has happened to me the same thing :crying:, and is a problem with the boot.img, if by chance your G2 version 4.4.2 and the the 4.2.2 boot.img, goodbye.
The only solution is to take it to repair a service official, there will change you the card, with the consequent change of IMEI.quent change of IMEI.

Sirs, I flashed the baseband (https://www.androidfilehost.com/?w=files&flid=12880) then it got working back.
solved for me
I have some kinds of that problem, let try:
Settings -> General -> PC Connection -> Select USB connection method -> Media device (MTP) (or whatever)
Got this same issue after flashing cloudy g3 rom. Then later flashing dirty unicorns, which requires jelly bean baseband. But even restoring g3 and 24a baseband, still doesn't work. No pc tethering and no on the go usb. My usb port is basically charge only.
---------- Post added at 03:58 PM ---------- Previous post was at 03:56 PM ----------
Everything else works fine...I actually never even noticed this bc I never tether to pc. But now I have to bc I want flask kdz
Help me please

I have a LG G2 . recently updated from vs98027a to vs98039a 5.0 lollipop. Since the update my computer won't recognize my device in download mode and I don't have superuser ppermissions. Help plz
I also have the same problem.
It happened when I tried to backup info through LG PC Suite: the phone disconnected during the process, and now it's not recognized by any PC (http://forum.xda-developers.com/lg-g2/help/lg-g2-recognized-windows-backup-t3155323).
Also found a description of the same problem here: https://www.reddit.com/r/lgg2/comments/2urpnw/lg_g2_usb_only_charging_not_recognized_by_pc/ - no solutions, too.
Did anyone manage to fix this?
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.

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!!

Hi guys.
Today I tried to unroot my phone and put it like factory to do the lollipop upgrade but I can't do it.
I used Super SU to completely remove root and do a factory reset using the key combination mode.
The problem is that my phone status is custom and I can't flash the original ROM because my pc doesn't recognize the phone.
I tried other computer, other cable, all USB doors and installing the last usb drivers on both computers and nothing solve the problem. It charges but doesn't connect to the computer.
I probably will send the phone to warranty this weekend wich ends on 23rd this month.
Please help me!
