USB Device Not Recognised on Bootloader

I have a problem. My Exec is stuck on the bootloader screen. All I see is Serial at the top, and v1.00 at the bottom.
When I connect my exec via USB, the screen continues to say Serial (rather than switching to USB) and the PC I connect to 'installs' the device as 'unknown device' in device manager.
I've seen mention of the problem elsewhere on the site, but the only solution I can find seems to be to keep trying, and eventually it's recognised. So far, after three days of trying, it has not been recognised.
I am aware of Buzz tool to get the device out of bootloader mode, but that required a connection to be established, which at the moment, I can't do.
Has anyone got any experience of this, or any ideas as to what's causing this, or how this can be fixed? I have tried uninstalling the 'unknown device' from device manger, restarting the PC (and hard reset of the Exec) then reconnecting, but the same thing happens every time.
Any ideas would be appreciated, as I'm currently staring at a rather expensive paper weight.

Try this it shld work

This is based on my experience with two UNis..one Exec and other JASJAR..both had same problem...this is how I solved :
-Put yr device in bootloader Mode
-Disable USB in Active Sync
-Now connect woth USB cable and open mtty utility
-Select the "WESUSB... " port
-You shall see a blank white screen..press Enter to get "USB>"
-Then type ( as BUzz has informed) set 14 0
(here I wud like to inform that after doing the above I did not get success so I typed set 14 10,then set 14 9 for two three times)
-Then I ran the ROM Upgrade directly(After enbabling the USB)
-I then followed the procedure as informed on the COngratulations Screen that is hold the two "-" buttons and soft reset and then pressed 0
-I got them back to normal..
I hope this helps to all my friends...Pls feel free..pls do not trouble our Buzz..he might be busy in inventing something more to our devices

Try it with a different USB cable or in a different USB port (don't go through a hub and if you've been using a laptop then try it on a desktop PC since some laptops have hubs built into them). If that doesn't work then you're out of luck as your Universal isn't detecting that you've connected to your PC and its time to send it in for repair.

Thanks Niketkumar - unfortunately it's the step before your suggestion kicks in thats the problem - the device won't connect to the PC, so when using mtty WESUSB..... isn't an option, only COM1 and COM2.
Shuflie, I've tried with three separate USB cables on a laptop and desktop (neither through a hub, and the same device has worked fine on both laptop and desktop before).
I fear a trip to the doctors is in order ...
Very frustrating because the PC sees a device, but installs it as unknown device. Anyone know if theres a Windows CE device driver that I could try and install as an overide (i.e. in device manager on the PC go to update driver and browse to a WinCE.inf or equivalent?)
Failing this, has anyone got any clue what needs to be fixed? Or how much it might cost?

i am stuck on the same problem and wondering the forum for almost 3 days now with no luck.... please help my device is in boot loader mood but not turning the serial to USB ......... please HELP.......

Please follow the steps:
1. Plug in ur usb cable in bootloader mode while it is showing 'serial' and version 'x.xx'.
2. Soft reset by pressing Backlight+power+reset pin WHILE KEEPING THE USB CABLE CONNECTED
3. your phone will now reboot into 'usb' mode. Don't remove the usb cable yet.
4. Remove the Memory card while keeping the usb cable still connected and VOILA,your pc starts recognising your phone as Microsoft usb sync.
5. Do whatever you want to do now (upgrade)
Hope it solves the problem now.
Press thanks if it does.

Something else to try
Having had a few issues with my G3 Uni, I've been through my fare share of Uni bootloader issues. When I find that I can't get the 'serial' to go to 'USB', I normally find it's because I haven't taken the memory card or the SIM card out (usually the memory card).
Make sure your memory card is out, then try to enter the bootloader and see if this cures it. If it does, then use mtty and the command 'set 14 0'
This tells it to reboot on reset. if you were to use 'set 14 1' it would go back to the bootloader on reset.

Stuck in RUU bootloader screen

My Wizard is stuck in the RUU bootloader screen and Windows XP comes up with the error "USB device not recognised".
When I connect to Windows XP the bootloader sceen shows USB at the bottom left but the PC (tried on 2 different machines) shows the above error.
Hard reset and soft reset do not work.
How can I get the Wizard to connect with the PC to perform a rom install or is the Wizard now beyond help ?

If the phone is already unlocked, plug the phone in the ocmputer. It should say USB on the phone when your on the Tri Colour screen. From that point you should be able to just flash any ROM you want. As long as it says USB on the phones screen, you should be good

No, that does not work beacuse when I run a rom install utility, I get the error (device not found).
If the pc does not see the phone, the flash utility will not either.
Is there a driver that can be installed on XP to force it to recognise the phone when connected to USB ?
Any help with this problem would be a life saver.

Are you unlocking are flashing
What knid of phone do you have

It's the HTC Wizard thats been running WM6 (TNT).
The trouble began when I tried to flash the latest version. The Wizard was recognised and the flash started, but at 0% the USB connection was lost.
Now the PC will not recognise the phone and it's stuck in RUU bootloader screen.
Tried all the USB ports on 2 different Windows XP PC's. Same problem.
Is there any method to get out of this RUU bootloader screen besides the soft/hard reset methods (because they do not do anything) ?

If the phone is already unlocked, your on the bootloader screen and the phone says USB. I don't see why you can't flash any ROM you want. I have never encounterd this issue.

yep, it's a new problem for me too.
Bottom line is, if I can't find a driver or some other way to make the PC see the Wizard. It maybe time to bin it :-(

Mate...I feel for yah, I got the same problem and tried everything. No one has come up with a solution for the phone and the PC to connect via USB when you get this error.

I dont know much about your phone but can you flash from SD card ?
It might be in the wiki section for your phone
here

it may be related to a faulty USB cable... or loose USB... i have mine do that sometimes and i have to make sure i do not move the usb once it is active synced!

Cant downgrade

Hello,
I am trying to get my hermes back to factory settings becuase I want to sell it. But I am experiencing some difficulties. I downloded the original shipped WM6 rom and launced the PDA Phone ROM Update Utility. With my phone conected to active sync, I go through the steps and at the step when they ask the check the boxes, the phone goes into bootloader. At this point the conection with active Sync is gone but my windows still detects it. ( I can hear the sound that plays when Windows detects a device in the usb). I clikc "next" and move along with the PDA Phone RUU. Then the RUU upgrade progress bar appears stuck at 0% and gives me ERROR[260]: CONNECTION.
I have to do a hard reset on my phone to get it to boot the OS.
I have also tried to flash with other ROMS but still get the same error in RUU.
Any help?

What OS are you using? Windows XP? Vista?

If you have Hard SPL V7 on your Hermes use the sd card method.
Format 2Gb or less sd card Fat32. Copy the .nbh file onto it and rename to hermimg.nbh. Put sd card back into Hermes and reset to bootloader. If all is right, follow the prompts.
Cheers...

I've used both xp and vista. still same result.
As far as using the microsd method, I have a 4gb sandisk microsd formatted to FAT32. Im geussing it has to be 2 gb or less?
Im still a little upset that this is happening. It stared doing this after I installed Tai's WM6.5 v9 rom.

On the XP machine do you have .net framework 3.5?
Also, you could try to download a custom RUU.
Cheers...

put your phone in boot loader mode, connect the usb cable, you should then see usb on the bottom of the screen of the boot loader, now load the Rom you want

You forgot to untick "Allow USB Connections" in activesync and to have Hard SPL on the Hermes. If you don't have Hard SPL then you can only flash the Shipped stock rom.

USB error, cant do nothing with it

This is a strange problem, I cant tell when it started but it did all of a sudden. When I try to connect my phone to my computer it all of a sudden does not recognize the device (it shows under USB in device manager as unknown device). This happens on my laptop and stationary one (XP and Windows Home Server). On my work computer and my girlfriends laptop (Windows vista) nothing happens at all. The only thing happens is my phone shows notification about HTC Sync (doesnt show the "mount SD card" option). I cant install modaco 2.x since it says it isnt signed when I try to run update.zip from "home+power" mode.
Anyone knows a solution? I really want to flash either modaco or the official HTC rom.

have you instaled HTC Sync + the Android SDK? Drivers are included, also ensure you have gone to settings > Application Settings > Development.. and selected USB Debugging in the handset
if you have done the above you should be able to...
Sync your device
Do a nandroid backup
Root your device
and flash, flash, flash
hope this helps

Thing is, all those stuff is checked. The strangest thing is that the phone doesnt even ask me if I want to mount the SD card (to make the phone like a card reader). I successfully flashed the generic rom again (so my phone is not rooted etc etc) but it still cant connect to any computer through USB (except from when in bootloader (back+power). Its really starting to bugging me since I cant transfer music to the phone anymore I tried a hard-reset, flashed a generic rom (the new one) and formatted the SD card (the phone can read and write to/from it without problems).

I've got the same problem for quite some time now and still no answers...! :-(
It seems very few people on these boards know of our exact problem and i've never seen a solution. Also not from the many people on these boards I consider guru's. :-(
I'm at a total loss here...

I will call HTC Sweden today and see if they can help me solve this issue. I will get back to this thread as soon as Ive been speaking to them. This is starting to really bugging me.

First of all, I would try reformatting your SD card on the phone itself via Menu-> SD card & Phone Storage. If you need anything on the card, you'll have to stick the SD card in adaptor and attach it to your PC directly.
Secondly, by the sounds of it you haven't flashed Cyanogens recovery image, or your HBOOT is wrong, if you are getting a problem with the signature on Modacos image. Either flash Cyanogen recovery, or follow the instructions found on another thread for restoring your HBOOT to an earlier version.
Regards,
Dave

I have tried to format the SD card already, didnt help.
What would the hboot have to do with the SD card mounting? I got the original hboot .0004 or somehting like that (never touched it).

This is the complete infor from my HBOOT screen (power+back).

Should I update something? And how would that help me get USB connection to work outside fastboot? Since its only working in fastboot and not in the android system itself?

Answer from HTC:
If you are getting the 'USB Device not recognized' error in XP, then your device has a faulty USB port. You need to call our repair line to gte it booked in for repair. That really is all there is, once the hardware dies and starts giving that error, there generally is no hope apart from replacing the USB socket or the whole motherboard. best regards, HTC Europe Support
Would have been nice if they could include in this message where I should turn etc?

I had the same error when I flashed my unit with wrong radio image (newer version) without flashing system and boot images. Then I reflashed those as well and everything worked ok.

Is there any update.zip containing all those updates? and would it void my warranty? ex, would HTC be able to see any difference to the hboot etc?

Looks like you have been usb bricked, look this forum for usb brick fix, its not the fault of the rom, it just sometimes happens. Got it once too, easely to fix.
Sent from my HTC Desire

Im not blaming the rom not one bit as its been running fine this morning up untill i did the backup.
I have read and read that much my heads spinning %-( there's hek of a lot to take in and being a rather noooooob im lost as to what i should do

Worstenbrood is right, that's.just a USB brick, don't worry, it's an easy fix. Search Modaco for USB rickrolled.
http://android.modaco.com/content/h...com/309939/usb-brick-rickrolled-b0rked-fixed/
You can skip step one.

Not to worry ? im bricking it lmao
I really aint got a clue about the fastboot thingy if you have a little time could you give me a step by step of how its done
cheers

Download the SDK and then use the command prompt to run the fastboot command from the Modaco tutorial.
There are quite a few guides for fastboot, just Google it

Hi
I just ran the command and when entered it said fastboot not found?

You need to run it from the directory containing fastboot.executive (in the SDK).

thanks for the replies
i have tried that but im getting 'adbwinapi.dll is missing from your computer'
i have re-installed sdk and still wont work?

Did you do this
Windows XP / Vista
Right click on the My Computer icon and select the properties tab.
Select the Advanced tab and click the Environment Variables button.
In the new dialog box dowble-click on Path (located under System Variables) and type in the full path location to the tools directory.
Has to be done for it to work
If you have never used sdk before Google for a good install & how to use guide

whooohoooo right solved the sd problem, new rom flashed and powered up Many Thanks guys "but" i still cant use the usb on laptop ?
When i plug usb in it the phone only charges ? and an usb not recognised message ?

did u install the htc drivers from the htc website? i was having problems with connecting my phone dowloaded those and un-installed sync and all was fixed!

i get 'usb not recognised message' every now and then on my home pc and the works pc both running Windows 7 64bit.
I found that usually when it pops up about
'usb not recognised message'
i just unplug the cable then back in a few seconds after the message then it usually connects ok. sometimes it takes a few attempts.
thats with 'HTC Wildfire_setup_3.0.5481' installed for the 64bit drivers.

Thanks very much guys for all your help managed to get the usb fixed by installing htc sync
But now i have another problem i noticed today is Bluetooth wont turn on ? is there a fix out there for this ?
cheers
