help! P8 lite doesn't connect to the PC - P8lite Q&A, Help & Troubleshooting

Hi, i'm a smartwatch user, i'm from italy, so excuse me if my english isn't perfect. I' an ALE-L21 smartphone, i was going to root it, i read anything about that one year ago, my warranty ended in december.
I reset my phone about 3 mounths ago, but i never tried to connect him to the PC via USB after the reset. This morning i unlocked the developer's options and i activated the USB DEBUGGING. I downloaded the hisuite program, but i can't connect the phone to the PC. I activated the setting in "security>PC Suite" (it was about the use of HDB), but the problem is that every time iconncet the PC to the P8 lite, it only charge the battery. I think the problem isn't the PC, because when (on the P8) i go in "developer settings>networks>select USB configuration", the option "only charge" is selected, and i can't modify it. when i disconnect the phone, i can change it in "MTP (multimedia transfer protocol)", but if i connect the Phone to the PC again, the setting "select USB configuration" returnes on only "charge" again! and i don't want to root the phone now, but at least to connect it to the pc tu have a backup of important files......
Thank you and excuse me for the english.....

USB problem with HTC Desire HD

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"?

marcussmith2626 said:
the device might have trouble enumerating especially in windows 8.1
plug it in as normal
then plug any other usb dongle in like a wireless mouse thats already been installed
this will force windows into enumerating the device
if it doesnt work then most likely the port is damaged due the water damage it suffered

it took me months to figure that one out - even microsoft and samsung hadnt got any ideas
its because windows 8.1 has changed the usb stack and requires that all drivers be digitally signed and has an identifer that the bios can read
this means some old usb device didnt work unless they met condition already although new drivers became available for most things but for some reason samsung havent updated their usb drivers in years (May 5, 2011 is last officall release) so im guessing thats why it doesnt fully work in windows 8.1 and im sure the problem is because its not properly signed so the device fails to enumerate unless you do the plugging in another usb device
other old phones work fine like htc and new samsung phones also work fine so its properly just a strange issue with the way the galaxy y handles usb

unfortunatly thats the only solution iv found for windows 8.1 - if you restart the phone or remove the usb cable you have to go through the process again of unplugging cable plugging back in then plugging any other usb dongle in after - its the only way iv found for windows 8.1 to enumerate the device

no i have not tried but i tried different usb it works when the phone is off, and connects to oden i might wipe my laptop to see if that works
Did you install the drivers before hand? If not look for them install them then go to device manager in the computer find the phone, there should be an exclamation mark right click and press update drivers or right click and uninstall, once the device is uninstalled unplug the phone wait a sec or two then plug it back in

Reformat computer or try different computer
Assuming, you have no problem with your USB port, USB cable, installed latest LG USB Driver 4.0.4, running Windows 7 or 10...
We need more detailed info from your part to tackle this problem. Are you running on stock rom, kitkat or lollipop? Are your rooted and do you have TWRP recovery?
Then, you need to disable "USB debugging" from the "Developer options" menu. Then replug your USB cable and you can now select MTP instead of charging only mode. Good luck.

i have fought the no mtp problem and everytime i lost. if you try new things they just dont work. what has worked was to reformat computer then it will work..
I had the same problem with my G2. Unknown usb device, and the error was: "unable to get device descriptor" or something similar. Tried all software solution without success, so i have started to looking for hardware defect. I've changed the usb module, but no success. So, as a last chance, tried another mainboard. And "tadaaaa"... That was the problem. So, start to look for a working g2 with cracked screen, as i did.

Can't connect Mi A1 to pc

Hey guys !
For a year now, I haven't been able to connect my Mi A1 to my pc. I've tried everything from connecting on another pc, changing cable, factory reset, developper settings, nothing worked so far
I'm starting to lose hope, thanks for the help !
At least, is PC identifying that "something" is trying to be connected?
If yes, then is phone side. Remember you've to change device's connection notification toast, once PC identified a device. Enter there and in its settings change from "charging" to "file transfer".
I've the same issue. Every pc does'nt identify nothing when i connect the phone. In USB settings menu, i can't select any option (Ffile transfer, tethering, MIDI....).
I had the same issue over a year ago, Xiaomi service center was the only solution. There is nothing you can do
I know this is a silly thought... but have you downloaded and installed the Mi A1 drivers required on all computers you tested it on?
