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?
so i rooted my note 5 sm-n920p phone using odin to flash everything i even had twrp flashed to it. the phone worked properly for months then one day i ended up switching off oem unlock forgetting it would trigger my frp lock if my phone had died well my phone died and when i went to turn it back on i got stuck in the frp boot loop i can get it into odin mode but it will not go into twrp recovery mode at all. i know how to flash the stock firmware to my phone but my problem is i cannot get any computer to recognize my phone it says one of the useb devices attatched to this computer has malfunctioned and windows does not recognize it. ive tried everything from uninstalling my usb drivers and reinstalling them and manually installing samsung android adb interface directly to the unkown device. odin will not pick up my phone and add it for me to flash it back to stock and factory reset it im willing to lose all my data i just want my phone to be able to work. if there is anyone with any advice or is willing to assist me to get my phone back to a proper working state id really appreciate it. also i am not sure if i even need the computer to recognize my phone not sure if i just need to keep trying different versions of odin but i know that my cable isnt the problem because ive tried it with my other note 5 and it works ive tried multiple cables with the frp boot looped phone that i have and i cant seem to figure it out why odin wont pick it up. as far as i know usb debugging is on and oem unlock is disabled on my frp locked note 5 please someone help me.
Right...
I'm going through the exact same thing right now. In all of the guides right now, it seems like theres always something that doesn't work out with our specific phone... lame sauce tbh.

NEVER let your phone die. Charge immediately if battery goes to 15%. You need a charged battery to do any flashing so yeah, you may need to replace or charge the battery to flash a 4 file firmware.
HI, I need help fixing my Z3 Compact (D5803).
-My phone had Android 4.4.4, had Root and had firmware 23.4.A.1.200 I believe. (some pre-rooted firmware)
-I flashed that firmware onto my phone a long time ago and its been running great ever since.
-Today I decided to try more flashing, I rushed it and accidentally flashed firmware for the Z3, not Z3 Compact, plus I forgot to turn on USB Debugging!!!!
-It pretty much failed flashing, tried to turn on my phone and I get the update failed screen.
-I researched it, looked into repairing it through PC Companion, but decided to try flashing again and still not seeing that I had the wrong firmware.
-It seemed to have flashed some of the way but had errors and stopped flashing, I tried turning on my phone but now I get nothing.
-No LED, no vibration, no Charge LED, no Update failed screen, no Sony logo, no nothing.
-The only thing I get is when I plug USB into my PC then into phone, it takes 10 seconds, then I get sound on PC and a notification saying (Unknown USB Device (Device Descriptor Request Failed) but still no LED light on my phone or vibration.
-I tried uninstalling the driver, I tried different button reset ideas, even tried the little yellow button next to the SIM card.
-I tried repairing it with PC Companion but it cant do that because it wont recognize it or respond to the (hold vol down then plug in USB).
-Didnt bother try fixing it with flash tool because I knew I'd have the same results as I did with PC Companion ^^^^^^^^
-I read some people say that the USB error can be a Hardware issue but I dont think it is because my phone worked fine before all this. (Unless the USB cable fried my phone some how???? lol
-I did make a backup before I did the flashing which I put on my micro SD card, and I had that out when I tried flashing so it should be safe
I think thats it. If theres any thing else that comes to mind that might help I'll add it in when I can.
Any help would be appreciated thanks!
Force install drivers using the "Have disk" option through the device manager control panel.
If the firmware that controls the USB interface and bootloader are corrupted, it's possible that it's hard bricked and needs to be recovered using JTAG.
I've had bricked phones due to hardware failures that caused the same error.

Thanks for the reply.
My phone wont show up on the pc anymore. wont show unknown device in device manager neither.
When I first plug it in the LED shows red for a little then goes away, so I think the battery is dead, i charged it but still nothing shows up on the pc.
I would like to try and recover it using JTAG. I know how to open up the phone and all, but I dont know how to JTAG.
Could you give me some video tutorials or step by step instruction on how to do it for my phone? Also what JTAG hardware and software do I need?
thanks :]
So something I noticed, I've updated my phone loads of times via firmware Finder and the update tool on my PC with no issues. So I haven't needed to update my phone for a couple of months so I had no reason to connect my phone to my pc. Yesterday I went to do the usual update procedure and plug my phone in and realised my computer doesn't recognise my phone whatsoever. My phone is unlocked and currently rooted as a side note. So I checked to see if I had fastboot and when trying to boot into it, it just reboots the phone. Does anyone have any idea what to do?

https://forum.xda-developers.com/hu...432e5r1p9b195-9-0-0-195-t3888894/post79832003 this way should work unless something has changed on your PC? E.g. drivers uninstalled?
Solved the issue. My cable must have been damaged at some point and would only let me charge the phone. Used a different cable and everything worked as usual. Thanks for the suggestion though
And I do think it's unlocked, because I re-flashed TWRP and it still works, Magisk flashed without issues too, so I'm not sure what suddenly caused MIUI to say it's locked
Another thing worth mentioning is that my phone is no longer recognised by adb, even though I went through the steps I had previously to make it work (doing things in fastboot still works, but no matter what I try the phone won't be recognised as a device using adb)
Edit: For some reason it's recognised as a device again even though all I did was restarting it into recovery and fastboot a few times, which I've done before already
Just Xiaomi things
I once softbricked my device and it didn't even show up in the device manager. I thought I was fu*ked, but after restarting the phone a couple of times and plugging to a different USB port my PC suddenly started recognizing my phone again.
Yet another issue, the previous update was from MIUI 12.0.5 to 12.0.6, so nothing much, but now when I updated to 12.5, the phone isn't even detected when connecting to the pc normally, tried with debugging on and off and with fastboot, just doesn't seem to be recognised as a device
I swear to god MIUI has a mind of it's own and just wants to troll me, I post here and it magically works again
