[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...
http://forum.xda-developers.com/showthread.php?t=877444

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] USB device malfunctioned

I don't really know what I messed up but my computer doesn't recognize my phone any more.
After flashing Ultimate 8.2 beta and Ultimate 8.2 it just doesn't work.
What could I have done the mass storage is working with everyone except me.
I included some pictures. I'd appreciate getting helped.

I solved my problem here's the steps.
1. make sure that you have a rom on your sd-card to flash (just in case)
2. do a nandroid backup trough CWM
3. factory reset your phone, reboot
4. uninstall the phones drivers from the computer. unless you have a computer which doesn't have them installed
5. Connect your phone into computer and let it install the sd-card drivers
6. remove the mass storage from your computer safely
7. install the samsung galaxy s drivers for your computer
8. plug your phone into the computer. now it should be recognized and you'll be able to flash to stock if you want via Odin

try uninstalling the drivers for your phone on the pc.
factory reset your phone.
Does it recognise in odin when in download mode?

The same issue. I have Ultibread 1.4 and wanted to flash the JVK but windows keep disabling it. Can't find the device either in normal state or in download state. Odin also didn't recognize it
I'm on win7 x86
Did a factory reset - still the same

I tried different cables and PC's - no luck Anyone !! Any idea?

Didn't help in my case. I did the backup and wipe/factory reset the phone. Enabled the debugging mode, removed kies and all the drivers, rebooted the phone and the pc, connected the phone to pc and had the same message Any idea where I could got it wrong?
P.S. ANd the phone is now extreeeemly laggy and unresponsive

Well this is brilliant! I have made it even worse. I thought thought, that maybe the kernel is the cause of the issue, downloaded the SGS KErnel flasher and flashed the CF-Root-XW_OXX_JV1-v1.3-BusyBox-1.17.1. After the reboot the phone is stuck at the GalaxyS logo and is not booting. I can get into the recovery and the Download mode but the phone is still not being recognized and when I try now to wipe/data or do a factory reset I get loads of red errors Please tell me that I didn't brick it yet

Do you have a rom on your sd-card? Flash it trough recovery.
Or doesn't recovery even recognize your sd-card?

It was in the previous kernel. But in the last one I've flashed there is no restore/backup functionality, although the backup might be actually be on the sd card

Well, there seems to be only a one solution.
You have to uninstall the phones drivers, and install them again.
Then plug your to your computer in download mode and it'll install rest of the drivers.
Then Odin should be able to recognize your phone and your good to flash stock.
But you really, really have to uninstall the drivers

Well I did it before. I uninstalled all related to samsung from the add/remove programs. Rebooted the pc and still getting this error. In the properties of the device in the device manager I have "unknown device". I don't have any drivers on the pc as far as I see. I install the drivers from here. Connect the device again and get the same error

Hmm.. I did change the computer.. Maybe you should put the drivers on a flash drive and go to your friends computer to flash.
The thing is that he does not have the drivers installed before either.
Don't know why it worked for me but... it worked.

I am going to try the last thing - I have a System backup from the time I definitely didn't have them on the PC and see if this helps....

Nope.... Didn't help.... I am completely desperate. Maybe anyone would have another magical solution?

Guys! ANy idea? Plzzzzz. I'd do anything to get it back to life

Me too i get "unknown device" when attached with usb in download mode...ive been trying to get it back workin for a week now...tried everything...which means i can't flash it to gingerbread
Anyone got any ideas ?

I have tried different PC's and it's the same. Is there maybe a way to reset the device somehow?

Hi!
I have a similar problem.
For few days, I cannot connect my SGS to my Notebook.
I have windows 7 x64 installed, and it has never had any problems with connections.
Now, I don't know why, but I cannot connect it.
I tried to connect it to another computer, which has windows 7 x86.
And it was succesfull!
Now, it seems, that I don't have a hardware issue, but I cannot imagne, how I could solve this problem.
I already tried these:
- remove drivers/programs
- tried other USB slots
- downloaded newer USB driver for x64
- removed USB drivers (all of them)
- unplugged my notebook for over 5 minutes (also removed the battery)
Every time I plug my SGS to my PC only this message appears:
"unknown device" - or something similar, because I have a hungarian windows 7.
Sorry about my english.
Has anyone any idea?
Thx for advance

[Q] Bricked and not recognized by usb..

Hello there,
I am Belgian so i'm gonna try to do my best to find my english somewhere
I have a samsung galaxy s3 mini gt-i8190..
I have tried to flash with odin thru pda BUT it stopped with fail as result..
Then i have tried to put original firmware back the same way but fail again,
then tried again with same original firmware and succeeded..
Phone froze at samsung logo, tried again and now i got the message "firmware upgrade encountered an issue. please select recovery mode in Kies & try again."
Ok, so i plug the phone back in the usb cable: Device Not Recognized! (windows 7 ultimate laptop).
I can get in to download mode: still not recognized via usb.
recovery mode DOESN'T work at all (3 button combo) just the error message at the normal boot and the download mode.
So basically i can't flash cause i can't connect, reinstalled drivers, used another pc, same thing...
It doesn't even charge the phone..
Odin mode says:
Product name: GT-I8190
Custom Binary Download: YES (4 counts)
Current binary: Custom
System status: Official
So does there somehow any file exists to put on my sd card to access usb OR a file to go into recovery mode.
Any tip is welcome, will try them all..
Thanks by advance,
yoni089

Have you tried installing Samsung's USB Driver? I know installing kies comes with the USB drivers but just in case. You might want to check if it's properly installed in your computer. Try reseting your counter first with Triangle Away. Please tell me more of what you did.
Click on the thanks button if I helped!

Change usb port and make sure all processes with kies are killed in taskmanager.
Open Odin. Put the phone in download mode and connect usb.

Hello,
Thanks for the reply's
I did install Odin first, when i flashed my phone it failed..
So i decided to install kies to make sure i had the right drivers,
Uninstalled Kies without the drivers. The phone was still recognized back then!!
Flashed it again and again FAIL!
Since then NOTHING works with the usb connection, windows does not recognize my phone "unknown device".
So it doesnt even know what it is..
Uninstalled the drivers and reinstalled them, rebooted my laptop with battery out for a minute but nothing works..
Also i tried to connect to another pc but no luck..
So i guess the key on my phone for the driver to find is missing/deleted by flashing and failing..
That's why i asked if there is any file to putt on my sd card to be recognized by my computer.
I did tried many times using another usb port..
Also tried with and without sim card/ sd card.
(btw: does they have to be in there anyway?)
Thnx and grtz,
Yoni089

I know that, my connection worked fine i did see the com: port in odin and it said "added!".
then i started flashing again and suddenly "fail", got the triangle, went back to download mode, tried to connect again and windows OR Odin didn't recognized my phone anymore, device not recognized and no "com:" in odin.
Tried different ports, battery out for a minute, no sim, no sd, reinstalled drivers, nothing works..
That's the point why i made this thread cause i see no solution in this anymore, if i have no usb connection i can't flash ( OR IS THERE A WAY???), if i can't flash i probably can't get usb connection..

With what you're saying, it seems something has gone corrupt. Maybe a binary or an image. Flashing a rom using your phone might fix this but it's not a 100% success. It might destroy your phone more or fix it. It's a 50/50... :fingers-crossed:

No kies, correct drivers, tried different ports. Then I don't know. Are you using original USB cable?
I once got a bad flash like you did, but at least Odin detected it and I was able to flash this firmware with repartition, because official stock fw didn't work for me neither.

Anyone with the same issue ? I am stuck at the bootloader since I wiped out my system image I can get to the recovery but I don't have a way to transfer new ROM since phone wont detect USB (MTP).
I didn't have any image backed to restore to. Tried OTG cable/USB nothing worked
What are my options ?

Hi... Is data mounted and MTP enabled in TWRP?
Is your phone detected while in bootloader?
Try: fastboot devices
If phone is recognized, download stock firmware of your choice and flash it...

What operating system is installed on your computer?
Did you already install adb/fastboot drivers?
In device manager, while being in bootloader, is your phone detected when you plug your USB cable?
Did you try different cables, USB ports?

It is still under warranty but not sure if it will be honored since I have the bootloader unlocked.

Nothing like said it is dead. I have another nexus 6 can connect easily to the PC I am pretty sure it is a phone issue.

Tried that already it didn't work

Might be a driver problem.
Connect it your windows pc and check the Device Manager if it is detected as "Android" device. If so uninstall it and disconnect and reconnect it to the pc. Let windows install the MTP drivers.

Can I root my Note 9 withouth a pc?

Hello guys,
I think the charging port of my Note 9 is a little bit damaged, because I have tried multiple pc's and multiple cables and the phone will only charge and is not being recognized as a device on my pc's.
I would like to flash TWRP on my device to flash a custom rom after... But the official TWRP app in the Google Play Store is not showing an TWRP image for the Note 9 to flash.
Is there a possibility to get TWRP and eventually a custom rom on my device, withouth using a PC?
Any help would be appreciated!

no.
u cant use a an app that would theoretically need root to accomplish flashing a ccustom recovery on a non rooted phone.
regardless, u need Odin or heimdall or any app that can access the device via usb. search and read.
( u need samsung android usb drivers on the computer. )

Thank you for your reply.
I have used Odin a lot before for different phones. I've installed the correct drivers onto my pc's and used different kinds of cables to check if that was the problem, but the phone only goes into charging mode, when connected to a pc. I have read that a buggy charging port can actually cause that problem.
I think I do not need root to flash a custom rom. Flashing a custom recovery would be enough, I think? Correct me if I'm wrong. There is a mobile version of TWRP (the app) that could actually flash TWRP on a phone via the app. But the problem is that the TWRP app doesn't support the Samsung Galaxy Note 9.
I'm trying to figure out if there is another way to flash a custom rom onto my phone. But I need a custom recovery for that...

im saying that ud need root if the twrp app could flash roms within android. which implies ud have gone through the rooting process which has to flash twrp. plus i think the twrp app is just a downloader more than anything else.
anyways can you get to dl mode?
put phone off , hold bixby and vol down and while holding down the 2 buttons plug the cable from the computer
phone should go to dl mode

Yes, I can get into the download mode without any problems. But connecting the phone to a pc only charges the phone and I can not get any other option. I even tried to press the notification in the statusbar where it displays that the phone is charging (connected to the computer). But there are no other options than charging unfortunatelly..

in dl mode does Odin see a com port?
also maybe there is just alot of pocket lint in the back if the port. scrape it out with a very small needle or something.

Thanks. Odin doesn't see a com port. I've also cleaned the port and there is no pocket lint in it.

if you were rooted, something like chain fire's flashfire might have worked...

To rule out the charging port, grab the OTG USB adapter that came with the phone and see if you can get a flashdrive to show up in the phone.if you can't, the it's for sure the charging port .

Thank you for the suggestion! I tried it. It does recognize that there is a device connected. But it only let's it charge the USB and doesn't show up in the file manager. It definitely must be the charging port. Unfortunately...

Dumb suggestion, but you don't have the note in charge only mode, do you?

There are no dumb questions I have tried to put it into file transfer mode, but the option isn't available when pressing the notification in de statusbar. It only shows that the phone is charging and the phone goes to the battery settings when pressing the notification.
Also, I've checked in developer settings, and I set the USB configuration to standard: File transfer.

download mode( vol down +Bixby and insert usb from pc) overrides whatever "mode" the android software system is configured to.
