[Q] Unknown device - Samsung Galaxy S

Hello,
My Samsung Galaxy S is listed as Unknown Device.
It started after an update to 2.2 via Kies and i did that with the regedit exploration. That was the 2.2 beta and then i updated it again with the official release this time also with the regedit exploit. I have formated the internal SD (i cant dismount it cause im on froyo i guess? atleast there is no option about it). Factory reset and so on.
Reinstalled kies 5 times, installed USB drivers again and again. I have tried it on different platforms with both XP (32-bit), Vista (32-bit) and Slackware Linux (32-bit). The computors just cant find drivers for the device.
I have tried all the different usb options in the phone settings nothing happends. I think i have tried everything that can be found here and on google...
The phone is Rooted and im now on PDA: I9000XWJP6, PHONE: I9000XXJPM, CSC: I9000XEEJP4.
Build Info: 2010. 10.
I believe the main thing here is that i dont even get the MTP application in the phone to recognize that a USB connection have been initialized. Nothing happend in the phone when i connect the USB no MTP screen or anything, just chargeing. I have tried 2 diffrent usb cords both that worked before so its not that.. The computor just says unknown device and Kies dont notice anything at all.
I have tried installing another firmware with Odin in Download mode and stil unknown device.
So i believe the phone have, in some way lost its internal usb drivers? I have also noticed that the battery "100% charged" icon does not disapear after i disconnect the usb or the charger. Also sometimes the icon continues to charge after i disconnect. Sometimes when i turn the phone of it starts by itself after like 2 min.
Anyways! What i was wondering is if there is a way to install an official firmware via update.zip volume-up+home+power?
When i try to install a customized rom with update.zip it says:
E:signature verification failed Installation aborted.
Cause of 3e bootloader? But i think its best to maby have a good stable firmware before i go customized?
So any help would be appreciated!!! heeeeeeeelp.....

Try installing theses drivers x64 x86 depending on what operating system you're on.
If that doesn't work try going into download mode and connect with odin. With the recovery problem you need to flash 2e recovery
You can also try and download and flash the latest version firmware to your phone and see if that helps.
Good luck and tell me how it goes

Hi m8!
Thx for the reply!
I have allready tried installing those drivers doesnt work for me.
I have tried Download mode with Odin to, it still says Unknown Device in Windows (i have Vista 32-bits, but tried it on XP and Linux to).
So anything that has to do with a USB-connection seems impossible at the moment...
The phone dont start the MTP application at all and windows dont install the drivers, it just says unknown device when trying to install.
I just unistalled Kies and removed everything from regedit with "kies" in it and then rebooted and downloaded a new fresh Kies file. Installed it and rebooted again while i wiped the phone, formated the SD and did a factory reset.. still "Unknown Device" :[
The problem seems to be the software in the phone.. so my question is: Is there is anyway to update or flash the firmware in the phone without any USB connection?

Is there maby any way to get 2e recovery mode without usb connection?

There is an app in the Android Development section here that allows you to flash a kernel within Android. Never tried it myself but I believe it is now stable and you could use it to flash CF-Root internally
EDIT: Here you go...

Have you tried recovery mode? Big yellow triangle with Android man holding shovel. Then connect to PC with Kies running and click on firmware update button.

Thx man!
But it seems that i dont have root access anymore, so cant use that app either :/ i think im a hopeless case.. :[

Yes man.. i get the same thing with the Yellow friend that says "Do not turn of target!!!"..
"One of the USB devices attached to this computor has malfunctioned. And Windows does not recognize it."
and also
"Unknown Device Installed
The software for this device has been successfully installed.
Unknown device - - Ready to use"

Are you connecting through a hub or direct to the back port of the PC. A hub will cause problems. If direct then try this.. Plug in and wait till you get the unrecognised device info. go into device manager, identify the device it will either say Samsung or unknown device. right click and remove device say yes if it asks if you want to delete the driver. now restart the pc after unplugging the usb then after it has fully restarted and connected to the net plug it back in again. Hopefully it will look on the net for the driver and install the correct one.

Yep tried that to.. i have even tried it on 3 diffrent computers 2 of them in all usb ports.. and everything els works that was connected in those ports.
I dont think its the software in the computer that is the problem.. :/
I believe there is some internal (in the phone) usb firmware problem, if thats possible?

i have exactly the same problem my usb by giving uknown device (i used it at 3 computer with kies software) it seems usb not working anywhere.
I believe our only solution is to find a way to install e2 recovery via the phone.

I have this problem also.
My SGS is rooted.
I tried everything. Googled many hour.
I din't know what more to do.
I have "Android system recovery <2e>" Is this an advantage?

I turned the phone in to my provider. this message is what i got from the repairservice.
Repair Details: The phone's charge connector is moisture/water -damaged, can not be repaired. returned without action.
WTF?!! i have been really careful with the phone. The only thing i can think of is that it has been really cold where i live (Sweden) and i had it in my pocket.. but i mean cmon! it goto withstand that!
I guess i have to wait for samsung to make it possible to update firmware via Wifi.

With Recovery 2e i think it can be possible to update your phones firmware with the update.zip file but i think you need to have your phone rooted.

All makes of Smartphone seem to suffer from, condensation problem .
Or at least thats what the service centres

I think so. I have my phone rooted and also ROM Flash Manager installed. The issue now is to find an european stock image to flash compatible with ROM Flash Manager
I looked for the stock firmware image (my phone has JF3) but can't find where.
Anyone?
I don't want to flash a cooked image just in case I have to ship the phone to the repair service.

Hello, I have exactly the same problem.
My SGS is unrooted, due to warranty, and alway keep it with maximum care (it is not a free phone...).
Symptoms are the same:
-It started after an update to 2.2 via Kies
-Absolutely unrecognized by windows (xp32 and win764) anymore
-battery "100% charged" icon does not disappear after i disconnect the usb or the charger
-turning the phone off it starts by itself after like 2 min.
More: incredible but sometimes when connected to car charger, I have the message "usb connected".
Already tried all possible (unrooted) tricks.
I believe usb internal drivers (if any) are corrupted (maybe by moisture?), how to reinstall them?
Maybe usb connector damaged; I have moved a little bit with a scrwdrvr the usb connector plate and clean with air and a thin blade but no result.
I will bring to service, as warranty is still valid, but surely they will discard me (I am optimist)
If there is any solution, please post it.

Hello,
Same here, can't connect phone to pc, mtp dont start on phone after connect it on pc !
Anyone know how flashback stock rom if its possible ?

Hi someone have a stock firmware for flash it in to recovery ?
I think i will try send the phone to samsung after reflashing for see what the guys from samsupport says about this !

Yes, if a part of firmware has been corrupted (with usb info for pc recognition) maybe the solution is to reinstall entire rom.
How to find a stock rom?
How to reinstall rom from SD card in a non rooted phone with no usb connection?

[Q] Unable to connect to PC

Hello
I have Froyo 2.2 I9000JXJPB
I used to be able to connect to PC but not any more. Im using Windows 7 64
I even tried and restored my laptop for factory condition and wiped out my galaxy.
Sometime when I connect the phone with the usb cable and PC would say unrecognized peripheral device and most of the times nothing happenes
it does not help if USB debug is checked or not
I even tried different usb ports in the laptop but nothing work
its driving me crazy
need help please

ok, put the phone in download mode and then connect it, try a USB port that connects direct to the motherboard, usually at the back of the tower.
also if that fails, try to uninstall kies and then re install it, that will re install the drivers.
then post back with the result.
EDIT: just realised your on a laptop not pc

Download and install these on your pc/laptop , your problem will be fixed
http://drivers.softpedia.com/get/MOBILES/Samsung/Samsung-Galaxy-S-USB-Driver-for-Windows-x64.shtml

Before postig my question I tired uninstalling and reinstalling kies. also tried driver reinstall option from kies
I downloaded the driver separately tried installing several times but it did not help...
Installation always endup with a message Device driver was not successfully installed
Unknown device device unplugged
Unindentified device device unplugged
If i recall correctly my problems maybe was with the last update with kies

if you go into computer > device manager and then select on the 'unidentified driver' you can select uninstall.
then start the process again, and also try installing it for the 2nd time with a different port.

very weird pb.please help

Hy guys,
I was trying the other day to flash a friends Galaxy S stock 2.2 but i couldnt connect the phone to the pc. In the pull down menu, it didnt appeared the dialog to click to go for usb mass storage or anything.
I've selected USb Debugging, clicked in the options for USB Mass Storage, and when i connect the phone to PC and cable, both play the connected sound, but still nothing more. What could be the pb? and how can i solve it?
Pleaaaaase help
And thanks in advance

also to mention. I'm running win 7 on 64bits, drivers installed correctly and my phone has no pb at all when it comes to connect it to the PC.
So....Odin not recognizing, PC not recognizing phone...what to do....?

try different ports or re-install your drivers(kies) take a look on the Themes and Apps section i saw a thread for drivers... try on a different computer....

have tried reinstalling the drivers, also using all the ports available on my pc. still the same pb.:-<

Definately PC issue. Reinstall Kies drivers.

Usb storage problem help!

Hi to all!
From Yesterday i have i sudden problem i never had.
When i connect my i9000 does not anymore show the 2 drives (usb storage of both internal external sd) on my computer.
I use Glitch kernel with latest cm7 kang.
When i connect the phone via usb to the pc,sometimes i get the erroe usb device not recognised (win 7 x64), and connects and disconnects randomly(always showing the error),other times doesnt do anything.
I tried cleaning the port,different pc usb port,different pc's, factory reset,different cable,older versions of glitch kernel or cm7.
Formatted also boot and system folders(of course also wipe data etc).
Installed kiss,boot the pc with phone off and then on.
Tried win7 x64 drivers.Sometimes i get on windows unknown device that i cannot find drivers that accepts.
On off usb debug mode and restart.
Nothing seems to work for me.
So id like to ask.....Should i try to go back on stock(firmware+kernel)?
And how is it done???
Or maybe its the port fault?

Any ideas?Noone?
Could someone please tell me how to go back on stock?
First to stock kernel then to stock firmware?
Thanks

The "device not revognised" error is related to USB debug mode, unless you have installed Google USB drivers.
Its not supposed to occur with debug mode=off.
Going back to stock (Leaked JVU) is explained here:
http://forum.xda-developers.com/showthread.php?t=1431596

Thanks for the link.
Going back to stock worked for a friend of mine,which came today(he has the same phone with cm7.2 rco and glitch kernel but with usb port working)by simpling entering on download mode and flashing with odin.Drivers installed (from samsung drivers folder,after installing kies)
On my phone,on download mode,or it doesnt say anything or i get on pc the message uknown device,cannot install etc.If i try to manual push the drivers it says the device cannot start.
So it must be a hardware related problem no??
In this case ,because i am still on warranty,is there any other way (for example via cwm) to put stock firmware and kernel in order to claim warranty?
Many thanks for your posts.

connexion usb don't work but "mtp connected"

Hello everyone,
Here the problem, I just acquired a Galaxy note and I can not connect to my Windows 8 PC (or windows 7) . Whether with or without kies.
In the device manager I have "unknown device"
I also tried odin mode and recovery of origin, but no way to install the drivers.
The galaxy shows in the bar notif "mtp connected" ( the smartphone is charging)
It is version 2.3.6. stock not root with kernel: [email protected]#2
did someone have an idea?
thank you in advance for your help.
Sorry for my english, i'm french.

U can set it in Settings > USB
But since u are using GingerBread, ur device might not be able to detect the usb port as more than charging port. This is very unlikely but it can happen..
And do Enable USB Debugging..

i have tried but it doesn't work too

uninstall kies and drivers reboot the pc. then download
http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
and install it without the phone connected. connect the phone and see what happens.. when you connect the phone, there will be notification of drivers being installed in the system tray of pc. click on it and you will see what is installed and what is failing.

Change ur usb cable to another usb port. This happened to me last time when I tried to flash new rom via odin. Everything is fine but the odin didn't detected it. b4 do that remember to install ur GN driver.
Sent from my GT-N7000 using xda app-developers app

i have tried to reinstall drivers but always the same problem "windows can't install the device...)
i have tried use 3 diferents usb cable too... no result
I would like change the rom (to see if it was the probleme) but it's impossible without root. And the phone don't propose upgrade OTA...

There could be a problem with the usb port itself. You could try to clean it and test again.

i have do this but no result...

Then it could be your mini USB cable. Try another cable.
Edit: Sorry, accidentally misread something. You tried 3 usb cables. My bad.
