I can't access to fastboot mode, i can't do anything.
PC Recognizes like "QHSUSB_DLOAD" in "devices and printers" but like "Care Suite Emergency Connectivity" in devices manager.
I can't unbrick because in devices manager recognizes like Care Suite Emergency Connectivity and i can't update the driver (for do the classic method for fullbrick)
When i try to install the qualcomm drivers it says that there is a better driver called "care suite emergency connectivity" and does not appear the qualcomm device with the port number.
Someone can help me

My problem is the following:
I decided to flash a custom rom on my HTC HD7, and started by connecting the phone to my computer (Win 7, 32bit) via USB while in Bootloader. The phone is recognized as "Qualcomm CDMA Technologies MSM" (HTC USB Sync) and the drivers installs correctly, but when I try to install drivers for the "Unidentified device" with WMDC the installation starts and ends shortly there after with the message "Device unplugged" and a message that the drivers weren't installed.
In device manager I can see the "Qualcomm device" but there is no sign of the phone (supposed to show as "Schubert" if I've understood correctly) or any unknown device. I've also tried this on another laptop with same OS but I get the same messages and no sign of the phone in device manager.
Does anyone have an idea of what's wrong?
You have to install " Mobile device center" in your computer before installing drivers
regards
I've installed WMDC but when i connect my phone there is no sign of it in Device Manager or any drivers being installed, only "Qualcomm CDMA Technologies MSM", and WMDC shows no connected device. The bootloader on the phone tells me that the phone is connected with USB, but my PC doesn't
show any sign of it.
Hello all,
I got an old 5830 Galaxy Ace I wanna hand over to a friend. I want to flash stock ROM onto it.
When I start the phone normally I can connect via USB cable and see the files on the device.
However when entering 'downloading' mode (power+volume down+home) I get the error: This device cannot start. (Code 10) "A request for the USB BOS descriptor failed." (copied from Device Manager properties of Samsung USB Composite Device). I also see this ballon pop in in the sys tray
The device does NOT show up in either Odin or Flashtool.
I am on Win 8.1 64bit laptop. I have searched and trawled the internet already and did the following:
- disabled signature verification in startup options of windows
- installed fastboot drivers via flashtool
- installed Samsung USB drivers
- tried 4 different USB ports and two different cables (and also on another laptop)
Can anyone give me a suggestion. I have not found 5830 specific USB drivers for example (nor do I know if they even exist). Any help is appreciated!
Regards,
Roel
SOLVED...sort of...
I used a workaround. I used a Windows 7 computer and there it worked perfect.

hi, i had same USB problem, windows7 worked for this old phone
Hello,
I'm on CM13 for Honor 4x Indian version. My problem is that if I enter into the diag mode by entering the command 'setprop sys.usb.config diag,adb' with sudo privileges the QPST doesn't show the phone as connected.
After the entry of the above command I could see the Qualcomm driver 901D detected by the device manager of Windows 10 lappy. On opening QPST I could see the port getting populated which is same as the port detected by device manager. But the 'Phone ' column says 'No Phone'. And further is I open the QXDM with the port enabled, I dont see the fields enabled like say NV(no white background) and instead shows grey background indicating the phone is not detected. I have another Qualcomm chipset Android smartphone with which I could see the phone getting detected by QPST& QXDM and could see various NV fields.
Please guide me in solving this problem.
Thanks

My intention is to backup QCN of my Moto X4 (XT1900-1). Currently I installed Motorola latest USB drivers and installed Qualcomm HS-USB QDLoader.
Device is booted with BP mode and Windows (7) shows three other devices called "moto x4" with a device called "RmNet". I select the first device then right click -> update driver -> let me pick from the list -> Motorola "USB QC diag" and force install it.
However when I launch QPST (2.7.472) at the port's tab COM15 appears however at "phone" column it shows "?(0)". When I try to backup the QCN I'm only getting 4kb of data and QPST shows "memory error"
I tried QFIL also, it's backup/restore buttons are getting disabled when I choose that specific port.
I tried the same sequence in two other Windwos PCs (Win 10) same results.
Did anyone successfully backed up QCN before? can you share the details. Thanks
