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.

Cannot upgrade ROM: Could Activesync 4.5 Beta 2 be responsible?

I am trying to upgrade from Ivan's ROM beta 13 to beta 15... Using the MAupgrade utility... however, everytime the utility resets the device to start the ROM update i get "USB device not recognised" from my PC and the update fails to start... eventually i get a connection error message.
This used to work just fine... however, recently i installed Activesync 4.5 Beta 2. Could this be causing the problem...? otherwise i'm not sure what else might be causing this...
I have also tried running the tool in bootloader mode with and without "USB connections allowed" ticked in Activesync but with no success...
Can anyone help me please?

Trying to clear registry before upgrading ?
Have you tried to clear registry before upgrading?

Hi Kassel, thanks for your response.
I have done a hard reset prior to upgrading... wouldn't that clear the registry?
If not please let me know what else i can do that might help.

Also, it seems very strange that i can't seem to do the ROM upgrade from bootloader mode.
I think i might be having a problem with GetDeviceData as it seems to stay in the "checking the information on your device... please wait" for forever when i try to upgrade from bootloader mode.
If it does come up, then the panel which says which version is on my device and which version it will be replaced by is blank?
This is not the case if i try to do it through activesync (with the device set up as guest).
What might get in the way of reading the device data? I made sure it went from serial to USB when i plugged the USB cable into the device and i have tried different cables...
My bootloader appears to be V1.00
hmmm... any thoughts?

Same here...
I also have the same problem.
I installed ActiveSync 4.2
Alse after having installed AS, the MTTY program doesn't see the USB port anymore, just some COM ports.

Same to me too
I have ActiveSync 4.5 bata at work (Which couln't upgrade ROM)
while my notebook with ActiveSync 4.2 work fine

Wow, it's great to hear that people are having the same problem...
Is it possible to back track with Activesync? Is 4.1 still available?
If not, i think i still have an older version running at home (i hope!)...
Is this definitely the issue then?

I have ActiveSync 4.5 and upgrading my Jasjar was successfully done with the ROM Version: (1.90.96 / 1.13.00 / 42.47.P8)

Sorry for not knowing, but is that one of the AKU3.2 ROMs. Not sure if it should make a difference, but just curious.
Also, did you need to use the MAupgrade Utility?
Cheers,

What happens with the USB drivers after installing ActiveSync 4.2
The strange thing is, that I tried connecting my MDA Pro to a PC without ActiveSync on board.
USB ports were visible using MTTY
I installed ActiveSync 4.2 and only COM ports are visible in MTTY, the USB port has vanished.
Can this be caused by the USB driver that comes with the ActiveSync install ?
If I put my device in bootloader mode, it sais USB on the PDA screen, but the utility for the ROM upgrade doesn't see the PDA and comes up with a device not connected error.
I would really like to try out one of the new ROM's by Ivan or JwRight, but am unable to, because of these USB problems.
So please someone help !!!!!!!!

I have the same problem... if i put the device into bootloader mode, "serial" changes to "USB" but the PC comes up with "device not recognized"...

Problem with bootloader. Can't update

Hi mates,
I do apologise if the thread exists already in the forum- i wasn't able to find it. When i try to upgrade updating the bootloader first, my device freeses on bootloading screen (serial or usb etc.0 Now i can reboot my system with a soft given me by a friend, but i can't update. In the middle of the process an unrecognised device error pops up on my PC screen and the updating soft gives me a connection error. Now i followed every instruction i found, i did a hard reset of the device, it's Active Sync synchronized, but the problem persists. Can somb help me with that PLS????

Sometime I've had this error too, usually trying once more was enough for me.
You could also check your USB cabling, like remove any usb-hub if you were using one to connect your device...

i780 ROM flashing problem

When I try to flash a new ROM using the Mirage updater, after I connect the phone to the usb cable, Mirage show me the message " PDA Device not found". I have installed all samsung modem drivers, i have no firewall or antivirus program and still does not work to flash a new ROM. This behaviour appeared after I flashed the i780_DXHC4_Rev12 ROM. If anybody had this problem, please advice me what to do next. thanks

no experts here?

no this happen. Are you using XP?

First and only time when I succeded to flash the ROM (DXHC4 version), it was on win2k3 standard..Since then, I have tried to flash the ROM on various OS ( vista, xp, win2k3, win2k8..) with the same result each time: "PDA Device not found"...

Make sure to connect the phone to the USB cable when the phone is completely OFF. (take out battery and put it back in)
with the turned out phone connected to the cable, press DETECT,
and only then power up your phone.
I know some instructions tell you to go into bootloader mode, but I found that this is enough to successfully flash my device.
Make sure you run on XP and not on Vista.
Hope this helps.

thank you for your advice..unfortunately, it does not work also..after I press Detect and turn on the phone, Mirage send me the same message: "PDA Device not found"...if you can help me with other instructions, i would appreciate

Does your device succeed in connecting to the computer using ActiveSync?
Try disabling ActiveSync USB connection or altogether.
If you only want to install the PDA part try removing the USB modem drivers,
you don't need them for PDA only.
Try a different USB port maybe, Or maybe another cable.
I'm at a loss here...

Hi on this forum too!
You need to already have an active activesync relationship with the device.

I can make file transfer and PC sync with the phone.
I tried every USB port to flash the phone. But nothing works, only 'PDA Device not found' message. I think there is no solution for this problem...

u have to load the modem driver which is for i600... i had the same issue but as soon as u load the modem driver it works fine..
and u have to take out the batt and put back the batt then hold enter and Fn button while u press the power button.. and hold till the device is booted in emergency mode... then connect your USB cable..

nothing works...

Try to update your usb drivers...

gOOndu is right you must have the correct USB driver to recognize your phone. This is not the modem driver. You can test this by disabling Active sync USB connections and plugin your phone. If it has the right driver it should state hardware found (name of your device) and then hardware installed and ready for use. If you get a hardware not recognized then the driver is not correct.
Hope this helps you.

The problem is not with the OS drivers, which recognizes my hardware device.Also, I am able to make transfers from the device to the desktop and viceversa. The problem is with the Mirrage Updater, after I press Detect and plug in the device, it can not see my pda anymore ( PDA Device not found message). The only time when I was able to flash my device ( with Mirrage) was when I upgraded to DXHC4 version. Since then, Mirrage can not find my pda anymore, altough I use the same (operating) system as when I succesfully flashed DXHC4...

Hi guys,
I am trying to flash a ROM following the steps in the first post of http://forum.xda-developers.com/showthread.php?t=388067 . I tried on Windows XP, Vista, 7 without any positive results. I installed the Samsung i600 drivers, started mirage, loaded the bin file in the PDA section, pressed detect, started the device using Fn+Enter+ON key, but mirage kept saying "PDA device not found". I tried the above steps in different orders,no luck whatsoever. I have the following 2 questions:
1. booting the phone in DETECT mode means that you get the message "Emergency mode - You must push Detect BUtton of the download application befor you connect the usb port".
2. Do you have another STEP-BY-STEP guide on how to do this? Or is there another tool besides Mirage (which in my opinion is quite old)?
Thanks a million.

Which USB connection do you use? Front panel? Use one which is connected directly to the mainboard (on the back).

There is an i780 flashing guide available. I cannot find (or post) the direct link but it acknowledges this original post.
I spent several hours at the weekend trying to find a way of flashing my phone including installing virtual PC, etc, etc.
Eventually I found this to my relief and it worked for me in Win7:

Possible Fix to the Update Error [262] for noobs and pr0s

Hey Guys
I am a new member as you can all see, and i have been wanting to update my Touch Dimond for ages now but after installing the HardSPL, i kept getting Update Error 262 when trying to install a new Radio or ROM.
So after Reading Countless Threads and trying a million different things, i figured this out.
Start:
>>Make sure you have HardSPL 1.93 installed
>>Then when installing a ROM, take the diamimg.nbh file and put it into the root dir of your internal storage.
>>Then take another copy of that diamimg.nbh file and put it into the HardSPL folder
>> Manually Start the bootloader by holding down the "down volume" Key and Turning off the Phone, keep you finger on the down volume key ALL THE TIME, restart the phone with your finger still keeping the volume key down, the phone will now start in Bootloader mode.
>>Now connect your phone to the PC via USB, and start the RUU.
>>The ROM Installation will now start.
I hope this has helped, this is how i eventually got the installation to work.
Thanks guy

Haven't had this problem myself, but it's good to hear that you got the problem solved Well done mate.

How is the computer supposed to recognize the phone when its in the bootloader ? if i do what you are telling me to do the RUU doesnt find the diamond and the phone keeps saying loading!

I guess the flaw of this solution is if you don't have access to an OS or can't transfer the file through ActiveSync then you can't copy the file.
But the installer can still see your device in some cases. Make sure to disable "Enable USB connections" in the ActiveSync icon->Connection Settings... and then run the updater.

your all missing the point, you can flash from usb directly from bootloader!! al the ruu does is switch the device into bootloader mode then flash, if your device is already in bootloader mode it just flashes.
so if you run the ruu and get error 262 disconnect the usb, you will see the word "serial" appear, then reconnect the usb and after a driver install "USB" will appear.
can i just ask, all you people have the correct active sync driver installed right? i.e. the ones i posed in my thread HERE If you are using vista or win7 you MUST FOLLOW POST 2!!
if you do not install these drivers vista and win 7 CANNOT communicate with the bootloader.
verify you have my drivers installed and then post back please

to be honest, i did tried your drivers, but have two problems
1. if your drivers installed, when in bootloader, windows7 (vista) do not "see" my diamond, though cannot communicate with it
2. if i leave the "download drivers automaticly from the net" and windows installs his drivers, i do have communication with the diamond, rru also "SEES" it, but mtty doesnt work with those drivers.
<tried both win7 ultimate and home premium>
workaround that i find usefull and works for me, is to have xp as a virtual machine, using your drivers, so mtty work fine
