Hello, dear friends. My lg g watch shows in device manager as "unknown device" with no vid&pid (win 7 at different computers) or "device descriptor request failed" (at win 8-10). So, any drivers doesn't work. The same situation at fastboot (unlocked) and recovery (twrp) mode. I have no success with factory reset. With smartphone lg g watch works good. Sorry for my terrible English. Please, help!
Problem solved. There is bad contact into charge station. I just ordered new on aliexpress.

So my phone doesnt connect to my copmuter. When i plug my phone into the computer it is saying that it found new hardware and that it is being installed. But after waiting a bit a window pops up saying that There was a problem installing this hardware: LGE Android Net MTP Device. An error occured during the installation of the device. The specified service does not exist as an installed service.
I even tested it on my friends laptop it has win8 and it connected without any problems but my laptop has winXP becouse of how old it is... so could this be the problem?
Install the drivers from lg's site first
Hi there,
I reached to the point i'm writing message in this forum cause I honestly tried everything.
Iv'e got a Lenovo s960 which I bought on eBay, recently he decided to make a software update to Android 4.4.2.
So what is the problem?
Iv'e got the phone with custom rom for int'l use (English and with google services), the phone updated to a chinese version without google services, and a bit of english.
Iv'e reached this conclusion based on the internet.
So why can I just root the phone and install another rom?
This is a really strange problem,
I found few information online about this but mostly in ended up without solution, so folks we got a challenge.
When i'm connecting the phone on USB, it's charging but not recognized, the computer "sees nothing", the phone just charging, like it was connected to AC adapter .
Iv'e tried a few computers, a few cables, and tried on Mac OS X and Windows. I noticed that there is a known problem between Win 8.1 and media tek chips, but ever after manual install no change.
The problem is in the phone, the usb option just disappeared, the is no "usb setting" anywhere,
I also tried to enable USB debugging but yet no solution.
Shortly I need to install other rom and to do this I need something to recognize my phone.
And now I have to be honest, I'm taking care of this case for a very close friend, it's huge favor for her, if it was mine I was just buying a new one.
Any help will be blessed,
Thank you
Yarin
Jumping I'm really out of clues
My LG L9 Optimus P769BK (T-Mobile) is stuck on Boot Logo. Hard reset or any other reset procedure in this world does not recover the phone to a normal state.
History:
-I rooted the phone a few months ago in order to get rid of some of the bloatware
-Ever since adware/malware keeps coming which made my wife's life miserable
- I unrooted it but that didn't change anything, the malware now resides within system apps so the misery continues
-The USB drivers are installed and the connection shows three entries in Device Manager
-LGE Mobile USB Modem
-LGE Mobile USB Serial Port
-LGE Mobile Composite USB Device
These are shown only when the phone is in download mode (VolUp + USB Cable In)
The only software that communicates with the phone and recognizes the USB port connected (Com41) is the LG Flash Tool V1.8.1.
Unfortunately this software processes the first 80% successfully until the reset stage after which the phone get stuck at the bootup logo (non-responsive) and never finishes the started flashing process.
I just want to re-flash it with stock ROM for which I downloaded v20h_00.kdz and converted the other required DLL, FLS and BIN files.
I know this is an older model but it was seldom used and I don't want to trash it. Thanks for any response in advance.
PC Desktop: Windows 7, x32, Clean Installation just for this purpose
Update: OMAP driver added
I noticed that I was missing OMAP drivers that are specific for the TI chip this model uses and I did install them. Now the phone has a new entry in Device Manager as Portable Devices where two drives/partitions are listed (F:\ and G:\) These are visible while the phone is stuck on the boot LG logo. The LG Flashing tool still can't continue after the reset at 80% so there is no really any progress yet. Any clue anyone?
Problem solved
I finally solved my problem with LG-P769
I don't know why I couldn't succeed earlier but it turned out using a laptop is a bad idea. I tried Windows XP, Windows 7 and Windows 10. The final solution worked on my desktop with clean Windows 7. The solution was using the trick with Small HTTP server. I don't know why it didn't work earlier but it seems another thread gave me a little bit more details that I missed at the beginning (maybe the server settings)
Anyway, it seems that this phone model was long time forgotten since there was not a single reply to my original post except my two updates so it turned out I was just talking to my self loud, LOL.
Anyway, I would like to thank this forum for most advanced postings regarding the Android branch of cell phones. Regards to whoever found this interesting enough to read.
Hi everyone, i've got some problem with my phone.
Phone : HTC One Mini 2
Rom : NostromoPop 2.4.0 updated from 2.3.0 (in this thread => https://forum.xda-developers.com/one-mini-2/orig-development/rom-nostromopop-0-1-2-15-1-15-t3004418)
Android 5.1.1 Cyanogen 12.1 Unofficial
Rooted, Obviously.
Xposed framwork v87
I think this problem is more global than this rom or the phone. That's why I did not specify my phone or the rom in the title.
Recently, i can't acces to my phone on my PC, it's invisible. In the device manager, the MTP Device send me an error code 10 (the device cannot start). it worked fine 2 weeks ago.
Until then, the problem seems banal but ...
After trying several methods found on the net to solve this kind of problem (reinstall driver, edit registry, many reboots, ...), the mtp always don't work.
I try on other usb, on other pc, with other cable, same.
I try with 2 Windows 7 64bits and 1 Windows 10 64bits. On windows 7 they do the same thing. I connect the phone, it appear on device manager with no problem, but won't appear in "My PC" and after 1 min~, It show me the error code 10. And on windows 10, anything is good on device manager but the phone don't appear in "My PC" either.
Change MTP to PTP gray the menu but nothing more append.
But ADB work, Network sharing to USB work, And MTP on TWRP work.
I think the problem is in android but I don't want to reinitialize my phone right away. (Unless i have no choice)
My phone restarted alone during a ride with the gps. Maybe a causal link.
I am looking for ideas or solutions for this issue.
Thank you in advance
PS : Sorry for my bad english, I speak fluently the google translate.
No response ... At least I try
Hi everyone,
I have an SII GT- I9100 that I installed a custom ROM on a while back (probably 2 years ago). After a while it got badly bricked I don't remember what happened, and not only that
the charging port was also messed up so I couldn't connect it to my pc (pc wouldn't recognize it unless I held the cable in with force, but even that didn't work after some time).
It's been sitting on a shelf for about a year and I decided to buy a new charging port, replace it, unbrick it and give it to my mom.
I did replace it and I can connect it to my pc now but there's still issues. On my main windows 10 pc it gives me an error "USB device not recognized, the last USB device you connected to this computer malfunctioned, and Windows does not recognize it". (I've reinstalled usb drivers and troubleshooted with Kies).
I keep the phone in download mode while I am trying to connect it to my pc since I can't boot into anything (I have a yellow triangle and Samsung logo if I don't go into download mode).
On my laptop (win 7) I've managed to get windows to install all the drivers(even though it failed a couple times ?), I've also troubleshooted with Kies, still Kies can't connect to it.
I want to restore it to stock ROM but I haven't been successful. First Odin gave me "setup connection" error but then I rebooted the pc and it "worked".
Now it just says complete (write) operation failed.
I've tried 3 different Odin versions, nothing.
What bothers me is that Odin says "Added !" but everyone online to the people with similar issue says that they should reinstall drivers or talks about USB Debugging (which I can't turn on or off since it's bricked).
Sorry for the long post but what's the move here? Am I using a bad ROM ? I've tried one for the country I live in but not the country from which the phone is ( I don't know the country, might be Austria), could this be the issue ?
Thanks in advance!
Update, I may have found the right ROM, now it's stuck at boot.bin
EDIT: Found a youtube "solution" to that, then it got stuck at cache.img
EDIT: Getting Driver issues again, Unknown Device :/
