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

Just noticed your user name, I was a big Amiga fan a few years back, still fire up Amiga forever occasionally on my PC when I feel the need.

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.

A lot easier than to root this device

Samsung SGH-i780

Hello
I am new to this site and was hoping someone could give me a some assistance. I recently used Mirage 1.8 to update my i780 to WM6.1. the eboot and the PDA installed just fine but I can not for the life of me get the phone and phone boot loader update to install. I am using the i780 Phone Upgrade ROM DXHH1 file, found it on this site. After I click detect and then power up the phone I hear the connection sound on the computer that the device is recognized and then the Mirage software starts its thin. Then I hear the disconnect sound and then Mirage goes through the Kw.kim retry steps. And the phone shuts down.
I have tried the modem drivers but I seem to be having a problem with them. I downloaded and installed this file "Samsung_CDMA_modem_4.34". When I connect the Phone it shows that it found the i780 USB device but then it begins to install Samsung Mit's USB Device and then it fails to install the device properly...so it does not complete the installation properly. How do I go about installing the driver properly? I do not see it on the list of devices in system manager, where can I manually update the driver and were do I find the file once the software is installed. Or do I need to try something else?
So I just tried a WM6 Eng rom and it all installs fine but just like the WM6.1 I can not get the phone to turn on in the wireless manager. What do I need to do to get the phone to turn on?
Thank you.

DXHH1 is meant for Asian version of i780, what's yours? for which country?
And can you please tell us if you are using XP SP2 or 3 and not Vista because flashing in Vista with Mirage Updater will NEVER work even if you have the right driver.
Try this. Uninstall the Samsung drivers frist and then reinstall it after reboot.
Then instead of using a separate DXHH1 Phone only image, download a full Russian PUHE1 IMG file (you can search for this easily in this forum) and flash everything (eBoot+Phone+PDA). If you can flash the Russian IMG successfully, you will be able to boot up your i780 in Russian langauage and only after that you can try DXHH1 IMG (I mean the full IMG rom and not individual files)
Good luck

You can flash using VMWARE (trial available) and install WinXP inside the virtual machine.. that's how I flashed your V4

disable USB connection in activesync...

People, here is a link to the Samsung modem driver:
http://fus.samsungmobile.com/i600/Samsung_CDMA_modem_4.34.zip

Thanks for the replys.
My i780 is from France and it had the French ROM but not any longer because I forgot to back it up.
I have XP SP3 on my computer.
I have uninstalled the drivers as well as activesync. Restarted computer. Then installed the drivers suggested by Mochan above. Then installed activesync.
Connected the i780...all of the drivers were installed properly (Samsung MITs device found and installed and i780)
Opened activesync on computer and unchecked "allow usb connections".
Reconnected the device and powered it up and the computer found new device and installed "Samsung Mits".
I downloaded both the Russian and the Italian full Rom updates.
Opened Mirage v1.8 and selected first the russian Rom for edoot+pda+Phone selected detect.
Plugged in phone to usb and all of the steps worked up till the phone image. It says on the phone "phone image downloading" and on the computer it shows "switching usb to phone" and "Downloading phone".
Then for some reason the phone shuts down automatically and stays powered off.
Then Mirage brings up the message "Attempting to open com 0..." KW.KIM Create Retry (25) etc...Finally Download failed.
I have tried this with the Russian, Italian and English ROMs available. I have tried it with the following settings on the phone on and off:
- Emercency mode
- Regular restart of phone
- Reset phone by holding Red Green and Power button together.
- Removed the battery completely and restarted.
- Restarted with Sim installed and with sim removed.
- Settings/Connections/USB connection mode switched from Activesync to Mass storage and then switched back to Activesync.
- Settings/System/USB to PC "Enable advanced network functionality" selected and then deselected.
What am I missing?
Why does the phone shut down during the Phone.bin file download and not complete the downlad and install? Is there some setting that I am missing or a com port that I need to establish so they will communicate properly.
Everything seems to work on the phone even without the phone.bin file installed. The problem is that when I try to connect to wireless manager and enable the phone nothing happens and it does not register the sim card. Also In the Settings/Connection/USB connection mode I only have listed Activesync and Mass Storage. There is no listing for modem (I noticed in one of the other posts that they had the option to select modem). Is there something I need to do to enable this option.
Sorry for the long rant but wanted to make sure everyone had all of the info.
Thanks

my brother had a similar problem with his i780 - the phone refused to be recognised when flashing the phone.bin, the pda and eboot flashed perfectly no problem. We realised it was a problem specifically with the device as my i780 flashed all three parts fine.
In the end he got the device replaced which flashed fine!! Maybe there are a few dodgy phones out there! My advice would be to try and find a French rom and flash your device with that. Hopefully the rom will be compatible with the phone part of your phone!

Just downloaded the French rom from an xda thread. It would not load up under the eboot+PDA+Phone option but it did load under the PDA option in Mirage. Still can not turn on the phone under wireless options on the i780.
The phone/radio worked fine with the original rom. Once I did the first rom update to switch from french to english only using the pda update I lost the phone/radio functionality. So I dont think it is a hardware issue rather a software issue. For some reason it is not making the connection. I just dont know what it is. Could it be something with mirage? Why would the phone shutdown during the software install?

so looks to me that the problem is with the phones modem set up. I do not have it listed as an option for usb connectivity. Is there a reg edit or some other steps I should take in order to get the phone to set up the usb modem?
Thank you.

I still have had no success with my problem, has anyone come across any info about an official i780 update? Or does anyone know what I can do to get around my proble to install the phone rom? Thank you.

I have the same problem with apetrovic. I have used with phone off, which is a big pain. Just like a PDA with no phone. This is all happened after flash Russian image. The original rom was German. my i780 simply turns off after downloading and ends up with no port created.
Any clue, please.

I have downloaded your suggested driver, run the setup, restarted the computer and connected the i780 in Emergency mode with activesync disabled and the Computer keeps installing Samsung MITs Drivers and not the CDMA Drivers you supplied. I used the Add Hardware wizaer, interrupted the install process when the i780 is first connected and even tried the update driver option and I can not install the CDMA driver I always get the error that "The specified location does not contain information about your hardware." How do I get the CDMA drivers you provided installed and not the MITs?
Thank you

Yes, I have also tried to intervene the installation of the MITs driver to install the CDMA driver, and Windows XP sp3 says "The specified location does not contain information about your hardware." So, I could not install the CDMA driver.
I do not know how to get rid of the MITs driver completely, so that Windows XP does not even recommend this driver when I install the CDMA driver. Windows always complain the MITs driver is not signed.
I wonder if those who have successfully installed the CDMA driver also see the MITs driver in the device manager when i780 is connected to PC under the emergency mode. This looks important for the moment for you and I in resolving the issue.
Anyone who can tell us what driver is on when i780 is connected to PC under the emergency mode? Thanks in advance.

I think the problem for us is that we have lost the modem option on the i780 under settings-usb connection mode. Since we do not have the option the computer will not download the drivers. The drivers that are downloaded are prob ok because they are intended for USB sync but when you go to the device manager there is no i780 modem installed under modems...so my theory is that the computer is not installing the modem driver because it is not finding a modem on the phone. So we need to somehow get the modem option installed and available on the phone and then the computer will install the drivers and then we can properly install the wm 6.1 phone update. please let me know if you find anything out.

That's an interesting theory noticing the messages in the mirage loader.
"Switching USB to PHONE..." and then
"PHONE-Switching USB to PHONE...
PHONE-Automatic driver detection failed..
PHONE-Attempting to open COM 0...
PHONE-Port Create failed...: COM 0"
These clearly look related to the modem meaning we should be able to see the device under modem in the device manager of Windows XP.
In fact, my i780 got the phone rom flashed just for once successfully when I flashed the russian image (eboot, pda, and phone, altogether). I don't know what mysterious thing happened here, and then I have never succeeded back again in flashing the phone rom since then. My phone used to work no problem before this. I just wanted to have windows mobile 6.1, and now I know I should have clicked "PDA" in the mirage loader instead of "EBOOT+PDA+PHONE".

Well this is becoming more and more difficult!! I contacted US Samsung support to reflash my i780 and they can not do it becuse the phone is not sold in the US and then I contacted Samsung France and they cant flash it because they can not ship it back to the US. I need to have an address in France for them to ship it to. So now stuck with a phone that only has PDA functions.
If there is someone out there who can help me I would appreciate it. The problem is that I used the Roms available on this site to upgrade to WM6.1 and I lost my phone/radio function. Now my phone is stuck in flight mode. I was able to install the eboot and the pda bu the phone portion will not install. I followed the directions and installed just the PDA portion initially and it killed my modem/phone/radio function. Before the phone worked and modem was listed as an option under settings usb connection mode...now it is not.
I have tried to install a French ROM (because it was purchased in france)and that did nothing.
So if there is anyone out there that can help guide me in installing a functioning rom WM6 or 6.1 I would greatly appreciate it.

I didn't know that you are in the states causing the problems. Too bad. I have two questions for you to clarify the problem.
Before the phone worked and modem was listed as an option under settings usb connection mode
Does this mean you could see the third option called "phone" in USB connection mode in i780? Currently there are only two modes, which is ActiveSync and Mass storage.
I was able to install the eboot and the pda bu the phone portion will not install. I followed the directions and installed just the PDA portion initially and it killed my modem/phone/radio function
Does this mean that upgrading only PDA may brick our i780 not necessarily with eboot and phone? Because I keep thinking that, it may be eboot I updated from this site not turning on the modem in i780.
Sorry about your and my problem. Thank you for your feedback.

Does this mean you could see the third option called "phone" in USB connection mode in i780?
Yes there was a 3rd option but it was "Modem".
Does this mean that upgrading only PDA may brick our i780 not necessarily with eboot and phone?
When I first used the upgrade I used the i780 PDA portion only, as suggested.

Sorry but I think that there is a bit of confusion.
During the normal use of the phone, you never see a modem in the device manager.
You can see the phone as lan card (used by activesyc), as a different lan card (when internet connection sharing is enabled), or as storage device (if you enable the related function in the control panel).
No modem.
During the flash process of the pda section the phone is still seen as a lan card.
ONLY when the phone sectin is flashed the phone switch to phone/modem mode.
Going to the problem you must launch the phone flash process and ceck what happen in the meantime in the device manager.
Is a question mark present ?
There is a unknown usb device ?
And if is the case what is the pid and the vid of the device ?

I stumbled upon a website that had an image that showed a modem in both the device manager and the usb connection mode areas...I have looked for it to post the image but I dont know where to find it again...starting to get lost from all of the info I have come across trying to fix my phone...getting confusing now.
Anyway, here is what happens in device manager when I do the following:
-Activesync disabled - i780 in emergency mode - Samsung MIT's USB Device listed under Windows CE USB Devices
-Activesync disabled - i780 normal - 1st before WM6.1 is running it shows Samsung MIT's USB Device listed under Windows CE USB Devices. Then that goes away and windows mobile based device shows up under network adapters.
- Activesync enabled - i780 emergency - Found new hardware installs without error...look in device manager and there is a yellow exclamation point next to Samsung MIT's USB Device under Windows CE USB Devices.
- Activesync Enabled - i780 normal - 1st before WM6.1 is running it shows Samsung MIT's USB Device listed under Windows CE USB Devices. Then that goes away and windows mobile based device shows up under network adapters.
Now during all of the above steps there is never an unknown USB device listed. Also I tried using mirage with these same above settings and each time I get the notification that usb device not recognized and then the phone suts down and I get the KVM com port messages, and it fails to install the phone rom.
I would like to provide you with the pid and vid but I don't know what pid and vid stand for. please let me know and I will get it for you.
Thanks for the help.

Flash does not start: "Device not responding" with SpeedUP TOR ROM

Hi,
I need your help please. I flashed the my Diamond with SpeedUP TOR ROM V2 GER. Now I would like to flash again, because I have some issues with Wlan.
But everytime I try to flash the updater hangs at:
"Checking informations on your pda phone. Please wait ..."
After 30-60sec I get the error [224]:
"Device not responding:
The update utility cannot get response from your PDA phone. Please check that your USB cradle/cable is connected properly between the PC and your PDA phone. And also check your PDA Phone"
ActiveSync and browsing through the folders in my diamond are working. Anybody any idea?
Regards Benjamin

Reset the diamond with volume down key pressed. You come in the bootloader screen. At the bottom you should see USB. If you see SERIAL, then there is no connection with your pc, plug off your cable and replug it again till you see USB.
Give your pc a little time to detect device and install drivers, then flash.

did you hard-spl your device first?

my diamond stucks in the bootlaoder when i put into the pc i don't get usb, the pc says qualcomm cdma technologies msm searh driver but i dont have it please help

Sounds like you need to flash from your phone as per instructions from other thread:
First make sure you flash Hard SPL then
Extract the RUU_Diamond_HTC_Europe_2.03.401.2_Radio_Signed_Dia mond_52.51.25.26_1.09.25.23_Ship.exe file (or whatever one you are wanting to flash) to a new directory on your PC
Find the RUU_signed.nbh file in this new directory and rename it to Diamimg.nbh
Copy Diamimg.nbh to the root of Internal Storage
Hold in the volume down button + the back button (thats the top right button on the front to the right of the big middle jog control) + soft reset
Follow instructions on screen
When the process is complete (it will say UPDATE SUCCESS) then reset
If it says rom image not found then you may need to follow the thread about stuck at 0-5% and use NBH util to mod the image to change the model ID

Hi
It is look like you are trying to flash a GSM rom to a CDMA diamond. you should read the CDMA section about your problem. Do not try any GSM roms on the CDMA device, as far as i know GSM rom won't work.
Good luck

the phone just crashed, i didn't wont to update my ram, wen i want to hard spl i dont find a phone
when i hard reset the phone says
trigger usb host....
retry enter usb....
don't find a map in explorer to
what can i do is the phone for the bin
help me please

Your device in bootloader state. Can you see the connection changes from serial to usb? If confirmed so you have a good chance to go further!
Do you have a appropriate active sync driver on your computer? Did it work before? If confirmed you should activate - Connection Settings - so the PC can detect your HTC device by usb
You know the rest of the procedure!

i dont see any progress, i sopose i've dont have the driver,
the bootloader stays on serial and the active sync didn't find the connection

Hi
Disconnect phone from usb then reconnect to usb.
In pc install activesync driver which will be found by pc itself.
If this is not successfull left diamond connected and restart the pc it will automatically install activesync driver.
then flash a rom from pc.
Good luck

[Q] P350 fastboot bricked

So I used ROMmanager to get clockwork recovery mode. Now when my phone entered the recovery mode it just say:
"Fastboot mode started"
"udc_start()"
If i connect my USB cable to it it says --suspend--
Now i tried using KDZ_FW_UPD in Emergency mode to restore original firmware but it cant find the phone. The log is:
[R&D Test Tools Log File]
10:50:59 : Launching SW update
10:50:59 : Unpacking KDZ
10:51:14 : KDZ file extraced
10:51:17 : Files were extracted.
10:51:17 : LGMobileDL Load.
10:51:17 : Port = -1
10:51:17 : Connecting to phone
10:51:17 : PHONE WAS NOT FOUND!
10:51:19 : ===FINISHED=== ​
I tried this procedure on 2 pcs but no luck. It seems that my phone can't connect to PC with usb cable.
I installed LG Moblie United drivers and disabled the lg modem thing in device manager. I am using Windows xp Proffesional SP3.
So does anyone has any clue what I am doing wrong ? If u need more info just ask.
Maybe if I try from some linux distro it will detect my phone ? But what tools to use then ?

Use fastboot to recover the phone. Check the wiki at the Troubleshooting section.

I recommend using drivers latest version. Last time I checked, United Mobile Driver was version 3.7.2 release 4.9.8.1 and Modem Link Driver was 1.0. I'm providing links for download from my personal Dropbox folder because I don't remember from which LG site I downloaded them from.

i had the same problem few days back... (ROM Manager sucks).... ok.. so.. before connecting the phone to the PC.. remove the battery, press both the volume keys (no need to press the power button)... and connect the usb.. now the cell phone will be in emergency mode.. try launching the software with kdz updater now... it should detect it.. after its detected.. connect back the battery (without disconnecting the USb cord ofcourse)... hope this works.. good luck

Good tip, adding to wiki later...

Didn't I said i did that ? My PC wont recognize my phone in fastboot or emergency mode, with fastboot being stuck at udc_start() and when i connect USB it says "-- suspend --" ,
I tried this guide madmanzrocks still dont see phone.
deleted lg modem, reinstalled all usb hubs, tried 10 versions of LGunited drivers, used both official update tool and kdz nothing works(can't detect phone), and also tried from cmd.
My problem isn't how to unbrick but rather why my pc won't recognize my phone :/

So, no feedback (USB Device connected sound) when conneting the phone? I assume you have tried all ports available.... Long shot, but maybe the phone's USB connector is dead... You have some background on electronics? If so, you can follow the service manual I reposted recently at the General section to check if the connector is gone (p. 113).

yeah tried all ports, I¨ll try on several other pc's. no connection sound, but phone is charging. I have quite some background on electronics so ill check it out when i try this on couple others pc's. Don't want to dissaemble it quite yet and if it rly is dead repair will probably take more money then i spent to buy it(I got it 2nd hand for around 50 $). It happened before that my PC coudn't recognize some devices but never like this. I ussualy get device not recognized, malfuctioned or smthing like that .

as I mentioned the same problem was solved bu connecting the cell phone with the battery removed. But if even that doesnt works for you, then maybe there is a fault in your PC. Does your PC instantly recognizes USB Pendrives? And which OS are you using?

I'm using Windows XP Proffesionall, all the other usb devices at least give a message if my PC can't recognize them. You know that yellow box that pops out saying device malfuctioned or smthing like that.

Hey, i have the same problem, and i also can' t fix it, i tried all ways, but my pc dont detect my phone... so i hope that someone will find a way how to fix it... but it' s not normal what is happening with this phone...

Don't know if it helps or you already tried it.
Start fastboot v2 and start the flash so it waiting for device.
Then plug in usb and start phone in fastboot.
That worked for me before.

I can try.
First start fastboot v2 on your computer.
Load the recoveryimage amonra or cwm5 (not cwm6)
Start flash so it say searching for device.(or something like that)
Plug in usb in computer.
Start your phone in fastboot.
Plug in usb in phone.
If that don't work you can try to instead of start phone first start it with usb cable.
Can need to unplug usb and plug it in a few times if the device say suspend.
Hope it helps.

Can you please add the links to this files or the files? I would be very thanksful...

Up to this point i tried all the methods you guys told me and some i found myself. Nothing worked for me as my PC stil won't recognize my phone, I have also tried all this methods on 4 PCs(2 had windows XP Proffesional SP3 with all the updates, and 2 had Windows 7 SP1 with all the current updates installed(note that 1 version was 32-bit and other was 64-bit).
My conclusion is that the USB connector is DEAD, even thought i can still charge my phone trough it. I probably won't be trying to fix this anymore as I've found an 4th gen iPod and i'll be using that from now on.It is true that i can't make calls(at least not the standard way, you know, it doesn't support SIM cards), but i have my old dumbphone phone for that and this will be used for just about anything else.
So thanks to all of you guys that tried to help me but i fear this is unrepairable. If anyone want's this phone I'll give it to you for free so you can have some fun cracking your head to see what is wrong . I only ask that if you find a way to fix it you post it here and notify me about it(send me pm).Otherwise do whatever you with it.

I have solution
