Samsung galaxy s 'usb brick'

Hi, to all.
I'm not sure i am the only one who has this problem on i9000,(i suppose not),
in any case i haven't found any thread related for our phone.So i thought it would be a good idea to start one,and if others have same problem, post here, so we can gather as much info we can.And maybe find a solution.
ANY HELP IS VERY APPRECIATED.
From what I've read on forum it's defined as: ''when a phone perfectly works but it is unable to make its usb micro port work in any way''.(Except charging).To precise, i mean make phone visible in download mode or able to enter in download mode,usb drivers install, transferring files to/from computer to internal memory and sdcard.
The only threads i found are for HTC devices,with no clear solution.
User Bejda gently gave me a link on a French forum with a similar problem.
It has alot of interesting info and personal opinions about the problem.
http://galaxys-team.fr/viewtopic.php?f=6&t=20841
Another link is this one referring to a program that can unbrick and make functional the usb port.
http://galaxys-team.fr/viewtopic.php?f=6&t=22257
POSSIBLE SOLUTIONS:
1)GOOGLE DRIVERS (As i use cm7) --Didnt work in my case
2)Other cm7 version or other kernel from CWM --Didnt work in my case
3)Other pc usb port --Didnt work in my case
4)Other pc or format --Didnt work in my case
5)Other usb cable --Didnt work in my case
6)Mobile Odin --Cant use that to put stock firmware as i need to repartition and pit, and these options are disabled.Can they be enabled??
7)Clean Usb port/Check if it is ok --Didnt work in my case
8)Use Jig -- Didn't work either.
9)Use the program from the above forum??
10)Heimdall --Finds uknown device with 0000 ids etc,and fails to install device.Does work.Tried latest version.
11)Tried toggling BT--Didnt work.
12)Having the phone connected to notebook and then turning the notebook on -- Didnt work in my case
12)APPLYING CM9 ICS! -- YES THIS SOLVED MY PROBLEM!!USB DISCS WORKING SO AS ODIN ON DL MODE!!!!!THANK GOD!
Can't think something more..
About my case:
The phone works perfect but i cant manage my pc to 'see' my phone.Charging works.
The 2 discs of the phone
or even odin cant be seen.I tried different pc's,usb ports,usb drivers/controllers,cables,download or not mode,usb debbugging on/off , samsung and google drivers.
Other cm7 versions or kernel versions.Formatting the pc also.Whereas my friends phone on pc works perfectly,mine 8 out of 10 times is not recognised ,or found as uknown device.
Discs (internal and sd) also not shown on my computer.
On 3-4 days of trying i only managed to get it shown for 1 minute(only discs) ,didnt have time to try odin,as it disconnected (without me touching anything).After that it did the same before(not recognized etc).
I also dissembled my phone and i can say usb port seems perfect.
I was thinking if i manage to make odin work i can repartion and (update bootloader????) also put stock firmware/kernel that may fix it ,or not???
Or at least with stock i can try samsung's warranty.
Anyway for now i use My phone Explorer (via wifi) that can access eveything (contacts,sms,calendar,both disks on root folders etc,and its free)
because ftp apks dont work for me.

I ran into the same problem a few weeks ago, tested it all that you write about, but eventually I gave up and sent it to Samsung, they changed the circuit board on the warranty and now it's on its way back from service.
I said I tried to update the phone in Kies and that something went wrong ....
If you have a custom ROM on your phone, see if you can "destroy the software" so that they can not get into the phone and find that you have broken the warranty.

Thanks for your answer.
Well,you were on custom firmware/kernel?
I don't know if this can be done as i am on cm7 and i use a non stock kernel.

if you are on a custom rom you could try odin for mobile to flash a stock rom and send it to samsung (if you are still under waranty) for repairs/checks

Hi,thanks for the answer.
As i said odin cant be used because phone is not recognised by the pc in any way

For me toggling bluetooth helpt ...

I had same issues, repaired by replacing micro usb port.

you replaced it alone?
sent it somewhere??
In anycase today arrived my JIG .
Even when i enter in download mode with Jig,i cant make Odin see it in anyway/or install drivers.
Tried also BT toggling as stated,but nothing.

I did sent to rma, but I have done for my friend, because he was out of warranty, not so difficult if you have proper soldering tools. Well its not cheap to get them, Im working with pc's motherboards, and soldering components is my job.

i hope you understood that i was referring to this

i had this problem so many times even with my ex-galaxy spica.
My solution is very weird/unimaginable : One day, my spica remained plugged in my pc portable turned off. When i booted my pc portable,in my bios screen, my phone said it was connected in USB. It was the better day of my life
Precision : my pc portable is very old ( compaq presario R3200 )
From that momment, every USBrick was just matter of time

Thanks,
sorry i read too fast.Problem remains also even with Mobile Odin.
I am on modified kernel and cm7.
If i try to use mobile odin to put stock firmware kernel i will soft brick my phone as i need to repartition and pit,and these options on mobile odin are disabled

Repair to a shop or samsung?
Claimed warranty or not?

i've got this problem to, you've probably got a faulty usb port, look into the port and see if you can find all the copper connectors, just today i tried a brand new usb cable, an that works!!!
only... it works 1 time, the first time the copper connectors aren't pushed into the cable, just look at an used cable and see what i mean, the connectors in the middle are pushed in....
what i think is that if you use a set of tweezers to pull them 1-2 mm out, (so they are lined up with the outer connectors) you can make contact again, make sure you're already in debugging mode, if you have used the cable you have to do it again..
btw, i havent tried the tweezers, i had a noever used cable laying around, but it's probably the same idea, so the same effect.... please reply if it worked or not...
btw^2 you're getting the "unknown usb device" error are you not?

Sorry for being late.These days i was ill
Yes maybe i have a faulty port.
But i can't claim warranty because i have glitch kernel and cm7 kang .
I just want to try 1st everything else possible , before a repair.
Also i don't like alot the fact that i will stay without my phone.
I will also try these days to keep it plugged on my turned off notebook (as oxmoss said)
and also try cm9 with cm9 kernel (as Dopedangel said).
Only sometimes (like 1 out of 10) it gives me unknown usb or usb malfunctioned,and (like 2 out of 1000!) it found the phone correctly.
These days , some times if i try to 'move' the cable near the phone it finds the uknown device
but i cant do nothing more. And sometimes i also hear the sound of the speakers getting 'stacked' when connect the usb..
So it must be the usb...
But the pins seem perfect.Also the ones inside the motherboard...
I tried with tweezers but nothing,as everything seems ok...
Anyway for now i use My phone Explorer (via wifi) that can access eveything (contacts,sms,calendar,both disks on root folders etc,and its free)
because ftp apks dont work for me.
Anyway i will try the above solutions and update these days the thread.
Thanks again

SGS GT-i9000 fozen on the first boot screen (Galaxy S GT-i9000 SCREEN)

I own a Galaxy S GT-i9000( bought at SFR)
When I connect it to computer I get the prompt that tells to choose between Storage, Kies...
But whatever I choose the computer tells me USB Device not recognised.
Now I was stupid enough to do the following:
I managed to root using Z4root by copying the APK file on external sd .
I got rom manager and updated my recovery.
I updated using the CM10-unofficial rom that is in the development forum: http://forum.xda-developers.com/showthread.php?t=1775169
The Mobile Network was not working so I did the following
I restored the nand that i did in recovery and now the phone is frozen on the first boot screen (Galaxy S GT-i9000 SCREEN)
Now I can go to Download mode but I can't go to recovery mode.
Let me remind you that my USB data connection is not working. So even though I enter into the Download mode I am not able to use Odin. If you know somthing that I am not doing, let me know.
So now I am looking for a solution that would permit me to flash without USB or allow me to go to recovery mode. Or a tutorial on how to change the usb port myself.
Thanks in advance.

You can try using Mobile Odin.
Also, you can try Heimdall method: https://www.fixmystuff.in/FMS_Forum...-flashing-to-original-rom-using-heimdall.126/

Hey
have you tried to connect it in Download mode??

Need more solutions
Thanks again to all of you that have answered me so fast.
Well I just finished trying all that you suggested.
unfortunately am still at the same point. Whatever I do, whatever drivers am putting in, cleaning inside the USB port with methylated spirit... Not getting Odin or Kies to detect it.
I read somewhere that when the data connection works, I should see the device named Samsung Device even before installing the drivers, but all I am getting is Unknown device. I still went ahead uninstalling and installing the drivers you provided and there is no successful outcome so far.
I still have faith. I have a little knowledge in electronics. I can open my phone and get to the usb port. My problem is I don't get any tutorial on how to replace the usb port. The thing is the connections are very tiny. I can also do with a bypass way that could make me install a 2nd usb port temporarily just long enough to flash the phone.
Or a hardware solution if I have to remove and flash a specific IC in a certain manner.
Thank you in advance.

hi there,
after doing alot of stuff to your phone that wasnt nessacary i'm not surprised it doesnt work er sorry . the only thing i can think of is the following whenever i have a problem with windows i go to linux, which is faster , much more efficient . so i suggest that you install linux ( ubuntu the best ) and try using odin with the linux version, it often detects things that windows doesnt see. other than that sorry cant think of anything else .
see ya

Look like a quite number of people are having this same issue and haven't got over it.
I just hang on and appeal to all of you cos I know XDA is the best place where I can get a solution.
Lemme know any suggestion... even the ones you are not sure can help. Am willing to do anything.

USB-connection (Smartflash, NVFlash, Data-transfer)

Hi,
I've search thru the forums and tried several things, but haven't found a solution.
My problem is that I no longer can make a USB-connection to my O2X.
The only thing that works in the micro-usb is charging. What I tried:
- Smartflash (power-up without battery while holding vol-)
- NVFlash (power-up without battery while holding both vol-buttons)
- Ordinary USB-connection (flash-drive)
- Cleaned it for dust
All of this was done on different windows machins (WinXP and Win7), all USB-ports and different USB-cables (inlcuding one that I know has worked before). Windows don't even show me the device.
The reason why I want to flash is that I think the current baseband (that I flashed) is not the best for my phone. So I want to try another baseband.
Do any of you have a suggestion on how to fix my phone or is the hardware toasted?
Best regards
Anders

Try going to Hardware and Sound and then Devices and Printers in the Control Panel. Maybe it'll show there.

You may try in a virgin PC where no USB drivers have been installed. Best would be format PC reinstalll WIN OS and try NVFLASH or SMARTFLASH after installing LG USB drivers. I have also faced similar problems and solved them in different PCs either friends or office. I somehow feel LGs drivers are badly written and not very smooth functioning. In fact I (and many others) have bricked O2X trying to upgrade to official GB updates by using LG PC suite and drivers.
This is only my suggestion. I did not had to format my PC any point of time. Don't curse me if this fails. This is only one of the trials and errors.

Maybe I should try from a Linux live-cd to check if it's windows or the phone who's acting strangely.

I got the exact same problem and after searching the net there are a lot of people having the same issue too.
Don't want to sound negative but the majority never got it to run again. For some it automagically started working again.
I got it to run only on Stock Froyo, no stock GB and no ICS with all the ICS Kernels available.
The thing which helped me on Froyo was: http://forum.xda-developers.com/showpost.php?p=28985033&postcount=5
Unfortunately CM9 has no secret menu.
I once had it recognized with Jarvis Kernel on Paranoidandroid for a second and had a hotreboot. Then never again.
I'm pretty sure the PC and the LG Drivers make no difference in this case, as I got 5 different PCs running different OS for testing and they never made a difference.

Does the ROM has anything to do with Smartflash- and NVflash-modes? My guess is that they have nothing to do with each other. So my problem should persist even though I try different ROMs. Correct me if I'm wrong.
I'll look into the Froyo-topic you linked to.

Strange. Now it suddenly works again. I didn't do anything from the last time. That's odd.

I don't think that the ROM specifically has to do with the problem.
Stock Froyo just happened to be the only ROM where switching USB connection modes made the device seen in device manager on Windows. (Although it required manual .inf driver clickery.)
I'm sure missing USB connectivity affects people in NVFlash as well.
In my case I can't do **** ranging from USB mass storage when booted up, ADB or NVFlash when booting.
However restoring to the Froyo nandroid makes everything working for me again.

oh oh, it looks like the same issue that i had... No PC-connection (Win/Linux) recognized the mobile via USB. No Chance to get it back to work.
I flashed back to stock (very difficult without NVFlash...) and then send it back LG Service for repearing. After three weeks i got it back. They changed the hole mainboard so i got a new IMEI but USB works now again.

Yeah. It stopped working after I booted a couple of times
And it was only semi working, it didn't want to go into Smartflash-mode, only NVFlash and Flash-drive.

Nope, as I'm quite sure that it's not a matter of drivers.
Windows don't even detect the phone. So I think that the phone doesn't present itself.

Since you already tried changing cables, computers, and even windows & Linux, and since it works on and off, You're right - it isn't the rom nor the drivers. it does sound like the hardware is messed up where the cable connects.
Any chance you can get it serviced? Hope your warranty covers it.

Same problem, no solution
Hi,
I seem to have the same sort of problem with my phone.
I used to be able to connect my phone to my computer just fine until I upgraded it to Gingerbread. Or that is at least the last time the USB connection seemed to work.
I have looked all over the internet now to find a solution to the problem but can't find one. Hope you guys could help me on this.
My phone is an LG optimus 2x P990 with a stock ROM gingerbread 2.3.4
LGE Version LGP990-V20r
Kernel version 2.6.32.9
I've tried so far:
- rebooting phone and pc
- factory reset phone
- Use other pc's => didn't work
- Connect a samsung phone to my pc with my LG cable => did work
- uninstall and reinstall all the necessary drivers
- mass storage mode on and off
- Installed android SDK and looked for adb devices, none shown
- phone doesn't show in the computers device manager either
Although when I do connect the phone it starts charging and if I go to the tethering settings it does recognize the fact that it is connected through USB.
So why can't I get my PC to recognize the phone.
I really need it cause I would like to root my phone to install a custom ROM.
I have tried rooting it with Gingerbreak as well, but that doens't seem to work either.
Thanks for the help

( vol down and then inserting usb) i plug in the usb without the battery inserted and without pushing any buttons and it still recognises it as an apx device, knowing this, ive tried nvflash and smart flash but both have no effect and dont recognise my phone. i will add that the version of ics that is currently out leaked. is very smooth, unfortunately bluetooth pairing doesnt work properly and wifi is a bit weak, but theres a fix for that.
i have tried flashing a cwm but to no succes. i do know some things in android flashing and repairs, but admittidly not everything so im not a complete noob.

well, windows MUST recognize the o2x as an apx device since you would use the tegra apx applications processors...
you are saying that windows sees your o2x as an apx device but nv/smart-flash don't?

[Q] Rooting w/o USB connection

Hi, guys! I have a really big problem :/. Right now I'm using the stock 2.3.4 gingerbread from LG ,but you all know that this is the worst OS ever. I wanted to get rid of it but i cant connect my device to the computer. It's only charging. I need a way to root it w/o usb connection. Do u have any suggestions? It's not a software problem! Something inside the phone is broken and i don't know what it is. Is there a way to root it via bluetooth or SD card? I didn't find any apps to root it too. I know gingerbreak etc, but they dont work for 2.3.4. Thank you in advance and i hope there is a solution. :fingers-crossed:

I am afraid you can't. Replacing your micro usb port could solve your problem. I reccomend to buy a micro usb port which is already on the flexible cable so you can avoid ironing.

So i'll need this? I asked a staff member in a service station and he said that the port isnt broken. So i need the whole thing port+flexible cable? Is that what i should do? Thanks alot. Ohh man i cant post links still: http:___//i.ebayimg.com/t/LG-G2X-Optimus-2X-P990-P999-Micro-USB-Charging-Port-Flex-Cable-Repair-Part-/00/s/OTU1WDE0MDI=/z/unUAAOxy9DRSAoTf/$T2eC16R,!wsE9suwycosBS!oTe7+VQ~~60_57.JPG

stupid question: did you try another usb cable or usb port?

Yeah, dude. Of course. I've tried different settings like usb debugging on/off too but still nothing.

here are some articles you might want to check out regarding usb connection

i forgot how the mass storage settings in gingerbread look like but there should be an option to put the phone in "charge only" mode (which you should disable)... pressing menu key in settings > storage doesn't give you any options to choose?

In gingerbread you can only turn usb mass storage and usb debugging on/off. These settings didn't help. I'll read more about the first link you gave me and try it out.

This is quite challenge, root without usb connection. First idea I got to use ADB over WiFi, but this is available from ICS, not on GB.
Second idea - what I remember, some of root methods use APK installation over ADB by script. Maybe you can search for these script methods and place all required files on SD Card. Then try to execute commands by terminal on device itself to install and root.
It's just my idea, maybe wrong, maybe help.

Yes that is what you need if you have to replace your USB port but you don't have skills to replace only the usb port.
You can try gingerbreak to root your phone, but it maybe won't work.

Gingerbreak works on devices with android 2.3.3 and lower. Anyways I've tried it but it didn't work.

I'm not aware of ADB and scripting. Can you give me sоme guidelines?(I'm sorry 'bout my english. I hope you understand)
p.s. I found some info about ADB. So you need ADB to control your device via commands, but you can use ADB on your computer? You say that i have to find a way to use ADB on my phone so it controls itself and roots?

sorry to hear about your problems but just a simple question here have u tried another computer ? i had this problem with my nexus when i connect it to the pc i couldn't transfer my stuff to it but adb worked, but when i took it to another computer both mtp and adb worked

Yes, I've tried another pc's port and it didnt find my device too. My issue isn't the same i mean that my computer doesn' recognize the phone. There are no messeges that appear on the device or computer.

Guys, the problem is not in the computer nor in the cable, it's in the phone. I'm 99% sure that it's a hardware problem. So i need to find a way to root or flash it without using usb connection.

i'm somehow sure that the real problem here is the device driver installation on your PC/Windows, not the phone...
btw which windows version are you using?
did you try checking out the AIO tool thread?

Win 8 currently.
How would this thread help me?
I'll try installing the drivers on this laptop cause i''ve tried before on a one with xp.
P.s. With the drivers reinstalled on win 8 it doesnt work. As i said i've tried different computers, different cables and different setting.

if you read the 1st post, you might find out how could it help you... especially if you use win 8 which caused problems for many other users when trying to install the drivers or trying to flash the phone...
I - Install APX (NVFlash Recovery) Drivers if not already installed.
It starts the windows device driver wizard to help you install the drivers needed for NVFlash. It detects your system OS and gives additional on-screen instructions needed if your PC is running Windows 8.
FYI: The drivers are located under ToolKitFiles\nvflash\driver folder.

I use windows 8 from a week. Anything i've done before was on a xp/ win 7. The problem isnt in the win 8 i use now. I've tried everything on my xp laptop. I have a friend who has the same phone and he can connect it to his computer so everything is fine with his computer. I've tried to connect my optimus to his computer and again it wasnt found by the computer. The problem must be in my device.
I'll try installing the APX drivers.
