Hi guys, i have probably killed my beloved kaiser.
This is what i did:
- Flashed latest Hyperdragon III Rom - all worked fine here
- Sometime later i figured out that the phone was not able to connect to my PC anymore (tried different computer and cable, no change: unknown usb device)
- I then entered boot loader and tried to flash an older rom (Garmin DK 3) but it stopped at 16% and i had to enter boot loader again.
The result:
Now no pc is detecting the tytn 2 correctly (unkown usb device) on boot loader screen. I guess that the usb port on the phone is somehow damaged. Any suggestions ?

I just want to say that your phone not connecting was a simple thing.

Did you try deleting your sync settings?
Delete device from sync list.
unplug/replug usb. setup device again.
Or I have also had to un & re install Active-sync.
Hope this helps
nonono .. its not that active sync is not working anymore, its that windows detects the device either as unknown device (on bootloader screen!) or does not detect it at all. I even cant select USB in mtty.exe - active sync disabled. Iam pretty much sure its an usb port issue since my tytn2 have had always problem with usb cons (did not recharge and stuff). Before that issue my pc had detected the tytn2 in bootloader screen.

Guys , all of a sudden Windows 7 has stopped detecting my Galaxy S . I tried reinstalling drivers / tried another cable . Tried usb debugging on/of multiple times , but to no avail . The phone is not even being detected in the Downloading mode via odin .
The phone is however working fine / charging with the cable as well . I am on Galnet MIUI twooey 3 . Can anyone help me out here ?
anyone ? i have been trying for 2 hours now . But to no avail
Check device manager to see if there are any issues with the driver.
Grab an ubuntu live CD, boot it, plug in your phone and run dmesg to see what it says.. You should see information about the device being plugged in (to at least rule out Win7 issues).
No issues found in device manager . I donot have the ubantu cd . Any other fix for this ?
tried formatting the internal sd card but no luck .Tried connecting the phone on a friends laptop , its not connecting their as well
is this problem related to the rom i am using ?
even after a factory reset , windows 7 is not detecting my phone . I need help
The most interesting thing is where ever i insert the usb cable in , windows its not even detecting anything at all . This is really weird , because just a day back everything was working fine .
Download the Ubuntu CD if you don't have it. Another option is to get terminal emulator from the market, then run the dmesg command right after you plug the phone in to see what the phone if doing.
Run the dmesg command via tha terminal app , connected the phone via usb and run the command . It is displaying a long list of things .
its displaying the same list of commands regardless if the usb is connected or not .
Can anyone help me out here ? I still cannot get the phone to be recognized by windows 7 . I have tried multiple original cables .
Only once it appeared in device manager saying unknown device , and further said that its some code 43 problem .
is this some hardware problem ?
I had this problem recently when I flashed cm7. What I did was put my phone in download mode THEN connect it to the pc and the drivers will be installed automatically. Let me know if this works.

Try to connect another PC and see if its detecting or not. If its detecting it is your windows problem. Download usb driver from samfirmware and see..
anyone ?????
I have tried connecting the phone on three different laptops . But none of them is detecting the phone .
I tried connecting it via tha download mode , but neither windows nor odin is detecting the phone ..
i have noticed one thing as well , the usb charging is going slow now as well .
Guys , can i install my jvo rom backup image over this galnet miui ? i am just afraid that if that doesn`t work , then i`ll be stuck with a non functioning phone , as odin is also not detecting the phone as well . And i`ll not be able to flash anything without it :S
suggestions ?
If you have the drivers uninstall them and reboot your pc. Then put your phone in download mode and connect it to the pc with the cable provided. The drivers should install automatically

buddy i just tried this one again . But windows is not detecting the phone in download mode as well
Does windows actually try and instal the drivers?
Sent from my GT-I9000 using XDA App
Nops . Sometimes it just detects the device and says that no driver found . And sometimes nothing happens .
This happens on all the laptops on which i tried . Shows there is something wrong with the phone . Is it the Rom ? or a hardware problem ? . Keep in mind that the phone charges just fine .
After hours the device is active (i9000t) the pc will detect it. However, when I try to get to download mode to flash another ROM, the pc won't detect it.
After I turn it on again, the pc still won't detect it. I'll have to wait a few hours before it will be detectable again.
The device is on stock ROM, not rooted.
Can anyone help me? I have all the drivers...
Thank you :]
Odp: PC won't detect the device.
Try another usb port
Sent from my GT-I9000 using xda app-developers app
I did. No change.
For USB,
(i) re-install these drivers 64 bit | 32 bit and then
(ii) check cable
(iii) follow this link for exhausted solution http://forum.xda-developers.com/showpost.php?p=27205737&postcount=4571
Try to update the USB driver by updating Samsung Kies.
It helped me.
Nothing helps... Thank you anyway...
"USB Debugging" in settings > applications > development > usb debugging - turn it on
This should help...

I think ur's usb is wrong
I have same problem, but phone does't detects only on PC (or notebook) with Win 8 64bit. I tryed other computer (win 8 64 bit), other cable, installed Sams drivers, Kies - nothing helps. But if i connect phone to PC or notebook with Win7 - it's ok, no problem. That's interesting problem with Win 8. It's was ok about 1-2 weeks ago on both my PC and note, and now i have this trouble on both comps...
Phone firmware is CM 10.1/
But my pc detects my note... the problem is when the phone is on download mode.
R: PC won't detect the device.
Have you closed kies? Are you shure that all kies process are closed?

Well I have just recently purchased a i9000t to use the aboard to fix my other one. Turns out I've fixed my original problem and now i can't connect to pc via usb. Only charges. After playing with settings on the phone the pc eventually detects something but it was only on modem and it was unrecognized and drivers wouldn't install.
Anyway after inspecting the usb port on the phone i can see corrosion right down to the soldering on the board where it looks like cookie crumbs.
So anyone having usb detection problems should inspect the USB port.
Hello people
I'm new here, in terms of asking questions and seeking help
I have the LG Optimus P970
A few days ago I made the update to ICS, and by proceeding with this page, hackmyandroid.com/optimus-black-p970-official-ics-update/3299
After that, not impossible to connect the phone to a PC, even the software update mode, it can not recognize, anyway to connect it just throws a slow charging.
Is there someone who knows what it is.
I'd love to go back to the old software, but there is no way to detect it pc
Sorry for my bad english
Thanks in advance
I forgot to say, before the update, and my computer still recognize the phone, connecting it over sony usb cable, now it is no longer recognized by the Sony USB cable, and I do not have original LG USB cable.
Perhaps this is the reason why a computer will not recognize the phone

I have the original cable, but still the same problem.
I have all drivers installed, I can transfer files between the phone and the pc, I can use the LG suite,
But I can't see my phone on the ADB console, I can't use smartflashtool cause the phone isn't recoginized.
yesterday I tried with lg cable, and wall charger, in both cases, said slow charging the battery, I tried on three different computers, I tried to reinstall the drivers, like the software blocked communication with the phone, just charge the battery.
If there was a way to put the software through SD card, it might solve the problem.
even the software update mode, the computer does not see the phone
Bro! For the softwaretool like smartflash, You need to boot into download mode i.e., You need to switch off the phone, plug in the USB cable connected to the PC and instantly press the volume up button. Then the tool will recognise Your phone. Try it and check once!
I tried it, nothing happens,
I go to download mode, but computer does not recognize it again
behaves as if the port is destroyed

Try to boot your PC with disabled driver signatures, or use a 32bit windows system.
try entering download-mode the following way:
disconnect your phone from pc
remove battery
press and hold Vol-up
connect the usb-cable (still without battery)
Now the phone should be detected as a serial-cable device an you can use the smart flash tool.
would have to be sound,
no sound when I connect the phone to the PC
Solved my problem.
Seems like windows automatically installs driver to the phone, but it partially works.
Unistall all drivers for the phone, or try on a new computer.
Plug the phone and cancel the driver search by windows
Install drivers for LG (unplug the phone before)
Turn it off
Plug the cable and enter download mode
And there is the phone recognized on smartflashtool.
I'm flashing a new one right now, thank you.
You do not understand the problem
there's no sign, no sound when I connect the phone to a computer, any computer, drivers were or were not.
As if something in the phone blocked communication between the PC and phone

Connection Problem with Mackay 2.999
Hey Guys,
first of all, sorry for my not so good English
I'am at Mackay 2.999 with last Kernel of his build and can't connect the Phone to the Computer.
It only install the LGE Mobile Composite USB Device, the LGE Mobile USB Serial Port and the LGE Mobile USB Modem on connecting to the Workstation.
I had test it on many Computers but the Problem is all the same: I can't get on my Memory or ADB.
I also had testet all modes under the setting point (MTP/PTP/mass storage device) and with debbuging on and off.
On my Workstation is the Last Version of ADB (1.0.31) installed.
Did anyone know the problem?
Did no one know a result to this problem
Hmmm my PC also can't read my storage what I did is go to cwm and plugged in usb cable and pressed mount storage it seems to solve my problem. I also did a cache and dalvik cache wipe.
Hey, I have found the result to this problem. You must flash another Baseband. Use from Nooby the V30 Baseband and it is solved.

Reboot your phone and computer then try to connect it again. If the same issue, then look at this post and see if it will help. I have also uninstalled the drivers, rebooted the computer and then install the drivers again but not HTC Sync Mgr.

If you have not done it already, try wiggling the mini-usb cable to see if it improves anything. Is the phone charging? It might be a hardware problem, I have read in some other post that it is the motherboard. Sorry, I can not think of anything else.

Yes i try to move the cable in the side of the micro usb, and 5 Or 6 diferents cables, and yes, the phone only charge.
Its very strange because I bought the phone used and only works one day and the second day lost the connection to pc when in try to unlock the bootloader, the first time no connected and suddenly work, I can only unlock the bootloader and stop working.

Try to clean the phone's contacts with a little rubbing alcohol and/or compressed air. There maybe lint or dirt on the contacts preventing a good connection.

Unfortunately that link does not work anymore. What was on it?
Asking because I got an m7 here where USB works just fine and reliably in both fastboot and recovery. But when the system (any ROM, tried more than 10 now), there's only charging. No MTP, no nothing.
Laptop's `dmesg` says:
