[Q] No USB connection between my HD2 & my computer

I have HTC HD2,I was trying to upgrade to Android, I think I made a mistake I installed “MAGLDR113” before upgrading my Radio to version 2.15.50.14. After I installed MAGLDR113 I connected my phone to my computer and the telephone was stuck in boot mode and was never able to see USB connection. Now my computer does not recognize my phone anymore and I can’t flash a new Radio version since I have no connectivity to my computer. I tried several things but all was useless. Can anyone help me telling me how I can have a USB connection to my computer??
Thank you.

do you have tried to start and hold volume button... than connect to usb and simply install a stock rom (for example from your provider) - this must work... if not - you have bigger problem.

Answered so many times. turn your phone off then turn it on "while holding volume down.It will then take to bootloader(rainbow screen).It suppose to have a cotulla written above the rainbow screen.Now flash it with a stock rom came from HTC site..No need to sync your phone to your PC..Just flash it..Start all over again..Now you can search before doing somehing with your phone.If that didn't help you. You have a bigger problem..

Yes I tried this also but it doesn't work.

What didn't work? Can you boot into bootloader - ie switch off, press and hold vol down button and switch phone on.
You should then boot into a multi-coloured screen and should see "serial" at the bottom of the screen.Then connect device to usb port (preferably one at back of your pc and a different one that you haven't used before if possible) - let the drivers install if applicable - does "serial" change to "usb"?

Do wat d above posters have suggested then try different usb ports or even a different windows pc...For all we know, your usb cable might be faulty....Also did u perform HARDSPL before anything else?

I've started experiencing this very same thing. HD2 wont regognize usb connection while in bootloader screen. I get the usb connection sound but never says usb at bottom of screen like it used to. I've been trying android builds via sd but wanted to try my first flash but cant even instal MAGLDR cos it just fails at bootloader cos of no connection. Has been driving me wild for 3 days now.

try plugging the phone into a different USB port it should work then...

Tried that all day and it said couldn't install drivers, then just tried the same ports now and its worked. I think it was mobile device center had 2 set-ups for my phone, i deleted the older one and all seems fine now.
This is crazy, now i'm stuck on magldr and won't find usb.

I'm leaving nand now cos i'm close to smashing my phone to pieces, magldr usb flasher will not find the connection no matter what i try, so i'm staying with ****ty windows mobile. Not happy but i've been trying for days now.

I am experiencing this exact same problem. Bootloader wont recognize the USB stays in SERIAL. Tried different ports, cord is fine. What is the problem.
Before this, my HTC HD2 would just hard reset on its own ONCE A DAY! Why was it doing this?
Now it gets stuck on the white HTC loading screen. Wont get passed it. I used to be able to hard reset by doing the volume keys down and reset but NOPE... still wont load past that white screen.
HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Have you guys tried deleting the drivers using a utility like USBDeview? Try deleting anything that relates to HTC OR HD2, replug the phone in, re-install the drivers.

Of course it won't work without drivers. The computer needs drivers to communicate with the phone. In normal mode, unplug the phone, Google the application, download it, open it, click everything that has HTC or HD2 in it and click uninstall. Plug the phone in, let the drivers install themselves again. Try again.

Ok... i rebooted into Normal mode, downloaded the utility, did a search for "HTC" found nothing, did a search for "HD" found nothing. So i am now installing windows mobile center for windows 7 which should have the appropriate drivers.

Install Windows mobile device center 6.1, problem solved.
Sent from my HTC HD2 using XDA Premium App

I'm able to view through USBDeview that my HD2 is connected, however I'm unable to view/open it.. I screwed up by naming the 'temp' folder to 'copy_to_sd_root'..
The instructions confused me. I figured this was the folder that needed to be copied to the sd root... however when i rebooted the phone, I was unable to access it. Any recommendations?

SOLVED
I was overlooking the USB Flash option.
If you are still having problems, let your phone turn on(no multi-color screen), select: USB Flash, click the DAF.exe installation file, follow the prompts.
You're done.

I had this problem and I solved it disabling an option in activesync. I can't remember what was exactly the checkbox, but was in "options" and it said something like "allow usb connections" or something like this.
I just disabled it and rebooted the device holding volume down.
Good luck!

Make Sure Phone is not connected to PC
Goto cotrol panel in windows
Uninstall HTC BMP USB Driver
Uninstall HTC Driver Installer
Uninstall HTC Sync
Unisntall Windows Mobile Device Center
Restart the PC
start the phone holding power and vol dn and now connect the phone to PC. should detect and install the drivers and you should be able to see USB on phone screen.
if this does not work
Delete all the USB root HUB but keep as last option in device manager.
PS: This will cause ALL the USB devices to redetect.
Let me know if this works

Help required - Bootloader only

Hi Guys/girls
I received my nexus 7 today (its lovely!) and then proceeded to attempt to root it so I can change the dpi etc.
I unlocked the bootloader using the Nexus 7 toolkit and that worked fine.
I then went to do the one click to root/flash etc and then got stuck on downloading boot.img.
After leaving it for a few hours I gave up and the nexus booted straight back into the os.
My next attempt was to root using the su binarys via fastboot. This again failed on sending the file. I also noticed that my device is locked at fastboot mode when the usb cable is plugged in, e.g the up/down doesn't work unless I unplug the cable. I have tried different cables and a different PC!
My next step was then to use the toolkit to reset back to factory incase I had screwed something up, so this deleted the bootloader etc as it should and then froze on sending the .img across.
I now have a un responsive fastboot when usb is plugged in and no recovery or bootable tablet, any hints/solutions?
Thanks

yes, actually : D
download this
http://forum.xda-developers.com/showthread.php?t=1809195
if you dont have that one.
pick your device from the list.
install the drivers for your device with device unplugged
make sure the device is fully off
plug in into the computer and hold down the power and volume buttons
windows should pop up saying nexus 7 bootloader driver successfully installed and then you can use the whole fastboot menu thing without a problem and reboot to recovery or whatever.
my suggestion is to install twrp recovery project 2.x.x.x
oh yeah, its a bug with the bootloader that it freezes when you plug the usb cable into the wall or a computer without the proper drivers

you are 100% positive you did EXACTLY what i said?

I have no idea what went wrong
That's the problem with toolkits though. People don't know what they're doing and when something goes wrong you don't know how to fix it!! I understand where toolkits come from, but they are only useful if you know what happens in the background when you click on a button.

I mess with several android and other devices on my notebook..
Doing so i install drivers for them and often have the exact same issue as you are having..
Do a search for a program called usbdview.. Install to your pc..
With the nexus unplugged run the program..Delete everything in the list that you do NOT HAVE plugged into your computer..Especially anything that says ADB.. OR ANDROID..
Plug in the nexus 7 refresh the list.. and delete the entries created for it..
Unplug the nexus .. reboot the pc.. Then download or use the tool kit to install the latest Adb drivers for nexus 7 ..
reboot the pc.. then plug in the nexus ..
After doing the above see if you can now use fastboot/ adb...
The above will insure its not a driver issue.Often computers get usb devices confused and causes them to hang ..
Good Luck

Put me on the right track, my PC was basically assuming that it was my S3, in the end I removed everything with samsung in it from the registry, uninstalled all the drivers then tried again, correctly showing as a nexus and not a samsung

Help!! My L7 is not working,black screen, no charges, QHSUSB_DLOAD what to do?

So I have bought a L7 and when I have it the phone is not working, the seller doesnt want to take my money back so I need help with this :S!
No appears to do anything when connected to charger
No led
No vibrates
No emergency mode
When I connect it to my PC it recognizes it as QHSUSB_DLOAD, but neither KDZ or LG update program recognize it :S!!
Someone know how to reinstall OS I think is software issue but I dont know how fix it
Thanks!

Try following the instruction I got from a website.
What is 'qhsusb_dolad' ?It is the situation when you can't boot into your phone,recovery mode and any other visible interface. When you connected your phone to the PC, the LED will flash and your PC will show that they were searching for the drivers needed(win7/8) but they couldn't find .......If it is commom for you to remove the battery when the phone did not shutdown completely or when you ran into 'No-Response' , as time goes by ,it will be inevitable that you come across the 'QHSUSB_DLOAD' situation .
But from now on ,you needn't worry about that for I have found a way out.
Tools needed:
Hardware: A PC running XP and higher (win7/8 recommended) and your usb cable
Software : MIflash and MIAssistent and a certain mi update rom(It is a *.exe file---fastboot file)
Steps :
1. Install the first two softwares described above(Run as administrator) in your PC (You need to disable the enforcement of digital signature while on win8 in the advanced startup (press 7 or F7)
2.Boot into fastboot mode(you just need to do with your two buttons and usually you cann't see the interface for your screen just won't show in this situation) before connecting to PC
3.Connect you MI2/S to your PC via the usb cable and the pc will recongnise it in the device manager panel(if not, update its driver in the unknown device---qhsusb_dload)
4.Open the miflash and click fresh to load your phone's serial number
5.Flash the update rom(the self-extracted-to folder) into your phone and reboot .
Explanations:
Miassistant contains the 'qhsusb_dload' driver for any phone and it enables the PC(Miflash) to recongnise your CPU serial which is the key part of updating by wire.
Tips:
Try this with your other phone, I believe it will work ,too.
I'm supposed to just copy/paste the link.. but the protocol won't let me since I still don't have more than 10 posts. I just want to help. Try this

[Q] Gionee E7 (32GB) got bricked

I tried to downgrade from Kitkat to JB via flashtool this morning which I often successfully flashed with the same method. But while the flashing is going on and almost finish the flashing (system.img, userdata.img, etc. are already flashed), there seems to be some problem and popped out that the flashing is fail. And then the device does not boot up. While I tried to reconnect the device to PC, the PC cannot recognize the device as shown in the picture. Unable to process any further method. Does anyone in this forum knows how to recover the bricked device like this?

The phone starts? In a black screen?
If the PC detects it like that the phone has some energy and connection...
Does anything apears on the screen? Can you go to the Recovery Mod?
Have you tried to force the driver installation on that USB item that appears on device manager?
Do you have access via ADB or fastboot?
Did you nottest in what partition did the error message appeared?
Please provide some answers to these questions so i can try to help you...

Nothing on the screen. Not able to boot into recovery or adb is not working. The phone is just death. But, when I insert the usb cable, the pc can detect it. I even approach the Customer Care here in Aizawl, but they cannot fixed. Even when I followed the instruction as per one xda member posted here, The qualcom hs - 9006/8 is displayed on the device manager and when I tried to flashed it with emergency mode, the result always the same. FAILS

Try this:
- Start GNQC with the phone disconnected
- Connect the Phone and see GNQC recognizes the QLoader
- If so, press power button until the phone vibrates
- Wait for the GNQC recognizes again the QLoader and press Download on Emergency Mode
Use this KIKAT ROM: https://docs.google.com/uc?id=0B8H5JoBDpTnJMGE2QTJPR0FWX0E
This worked for me, i had the phone completly died, not even recognized by the PC, waited a day and tried again.
Once the QLoader is recognized your good to go!!
I'm having another problem after that, now theres no GSM/3G signals....
I need a EFS backup with the TWRP recovery.... No one seems to have

I have the same problem, screen is completely black after trying to instal newer official rom. When I connect it to PC, it detects "hid device". I tried power + volume buttons combinations, but nothing changes. Sometimes notification led turn red for a few seconds but nothing else. And once win xp randomly detected phone as that "q..." thing, but it doesn't anymore. What else can I do?

Can anyone help me? I tried everything and my phone is still hardbricked.

Hello guys
Today i received my E7 and i tried to update via the tool unfortunately something went wrong and now i cant open it nor fastboot or recovery. Some hours ago i tried to connect via usb and appeared on the GNQC but later it showed as unknow device. It was my first day with the phone. Right when i connect /disconnect the usb i can hear the sound but i cant do anything. Is it dead or i can revive it somehow?
It was the first day:crying::crying:

Reinstall the drivesbob the PC, press 30 secs on the power button than connect the phone to the PC. If appears a QLoader port use emergency download on gnqc 1.6.9.0

H E L P - bootlooping, COM does not recognize phone

Hi everybody,
ill try to make it short:
My 6p has entered into the bootlooping mode.
I have never unlocked the bootloader/changed ROM/kernal.
After I let it bootloop until the battery is dead it's changing from bootlooping into blinking red dot. Then when I charge it for a couple of minutes it comes back to life after 10~ min it's bootlooping again - so I have a window of possibilities to play with the setting. In that window I have used the "OEM unlocking" option.
In the bootlooping state when I boot into the bootloader and connect it into the PC the device doesn't recognize that it has been connected and a PC ,and the PC recognize a entry of new device but doesn't recognize it is a Nexus 6p.
this situation is the same when I connect the phone when it is alive.
I have installed adb and fastboot with this software
https://forum.xda-developers.com/showthread.php?t=2588979
with the 1.4.3 version it shows in the end of the process "0 files copied" and then I tried the 1.3 version and it showed that 4 files were copied but it also showed an error.
I have also downloaded ADB from google site but it does not work either.
When I try to open the powershell in a folder where I have downloaded an img and type in a fastboot command the computer doens't recognize any type of command.
So if anyone can help me ill be glad.
Thanks in advance,
Matan.

What is the new device identified as....Qualcomm HS-USB QDLoader 9008? Your phone may be stuck in EDL mode. If that is the case you need to search XDA and attempt solutions for that problem first.
Did you previously have your PC setup properly with the correct USB drivers and it was working OK, or just now trying to get your dead phone to communicate? If the former it may be the EDL issue above. If it was the latter, the communication problem may just be the drivers were never set up in the first place. Have you tried a different cable or port on your PC, or another PC?
With no access to the OS you will be unable unlock the bootloader or access to ADB because those have to be enabled FIRST in the OS, so there's no helping you here until you can actually boot into the OS. Do you have access to Recovery mode? Tried a factory reset? If you don't have recovery, that was a major omission.
