Please help...big problem....

Big problem. Suddenly my phone will not turn on. Sits at the white Galaxy S GT-I9000 screen and does not boot. When I put it into download mode and plug it into computer, its suddenly saying "USB Device Not Recognized".
What do I do? PC won't recognize it, it wont boot. can't flash it.....I'm freaking out here...

Did you flash anything to it or root it?

Hi Rick. Try to re-install samsung usb drivers. during this time, take out the battery from the phone. once finished installing the drivers, put back the battery into the phone. Go into downloading mode. Fire up odin, put in the necessary firmwares + pit files. Once done, then CONNECT your phone to the usb port of your computer.
Hope it's okay.
Edit: Let's hope that it is the computer usb drivers are corrupted. Alterntively, if you still can't do it, try it on another pc.

Nope. I was rebooting it to flash XXJPC to it, but couldnt do so because it was saying that USB message and wouldnt detect it. So I went into recovery, did a factory reset, and now it wont boot.

Another computer does the same thing *tears*

*BUMP*
Lets try a different route. I will pay a generous sum of money to anyone who offers to and does manage to fix this for me?

rick, looking at this, if your usb is not recognised, it is either the pc or the phone usb port might be damaged.
if it is a hardware issue, then use the bounty to get it fix.

I was at that same point with my vibrant. After failed attempts of getting into download mode using buttons, here's what I did.
Download and install samsung usb drivers and android sdk.
Plug into the computer and use adb to get into download mode (adb reboot download).
Then flash with odin.
Doing that worked for me when nothing else would. Try it ?

I can get into download mode just fine.....my pc just doesnt recognize the usb device. tried 3 differente pc's, 2 running win7 and one running xp.

Did you install usb drivers on each of the machines?
Sent from my GT-I9000 using Tapatalk

I installed the samsung USB driver executable. and I also tried to use those drivers that it installs to manually update the "unknown USB device" in device manager, but they won't take.

Try uninstalling all drivers, then stick a MicroSD in your phone before plugging it into the usb.

Assuming you have Samsung Kies in your PC, try to upgrade it at 1.5.1.10074_45.
How long do you wait the boot?? The first boot after flash is very long, wait at least 5 minutes with flashing "S".

I did not just flash anything. My phone got really hot and laggy (as I was using it while charging it via USB port) and so I rebooted phone in an attempt to resolve the lag. when I did, it would not go past the WHITE Samsung Galaxy S I9000 screen, does not get to the flashing S screen.

if i understood you correctly, you have two separate problems:
a) your phone does not boot up
b) your phone is not recognized by any computer when plugged in
could be a coincidence, but probably is not. i'm guessing your bootloader got screwed up somehow. if it is a coincidence, it could be that your usb port on the phone is effed, or your usb cable is dead. try first using a different cable and see if your phone can be recognized by any computer. perhaps then you can go into download mode and reflash.
also, have a look at this post, might help you (although, if your usb is effed, there's not much point in trying any solution that involves your phone being connected to a computer): http://androidforums.com/780720-post3.html
EDIT: also, have your tried the obvious stuff, like pulling battery?

I ve seen many threads with the white screen problem ... it has in most cases been the drivers ... you desinstall all drivers from pc using Kies option for resinstall the drivers ... then you pull the battery off few sec (give it a min or two) then you get to download mode and you flash the beast ... dont connect your phone before launching odin or else it will not be recognized ...
for the few other people who didn't manage to fix it ... it was a hardware failure

That post you linked, is worth a try. But its for a motorola.....Where do I get my SGS bootloader to use instead?

ohh you were implying to try to use the motorola usb drivers?

I never said anything about a white screen. and I am not uneducated on flashing SGS, or using Odin. Far from it. My phone was first showing USB symbol when it wasnt plugged into USB port, then phone started running really hot while charging and got really bloated like it was overheating. So I rebooted and its now force closing at the first boot animation. I can get into download mode and recovery, but will not recognize in any of the 3 computers all running different versions of windows on them, with either of my USB cables that I tried.

[Q] USB doesn't recognize download mode. Stuck after installing speedmod kernel

I had rooted my phone previously running 2.1 and yesterday decided to try cm7. (I've flashed many G1 roms but none for Captivate)
Sorry this is quite long but wanted to give as much detail as possible
I was reading and watching the guides. Installed rom manager and flashed ClockworkMod Recovery 2.5.1.0
Rebooted the phone and tried to see if I can get into download mode by holding vol up + down and plugging the USB cable.
Once it booted tried to copy some other roms (zips) to the phone but the USB wasn't working on windows for some reason so rebooted in Linux. Phone mounted at first (for about a minute) but something happen and I lost the mount. I unplugged/plugged the usb cable but wasn't able see the phone as a drive even with fdisk.
So I ftped to the phone:
3buttonFix.zip
captivate-efsbackup.zip
cm7-captivate-initial-20110304.zip
speedmod-kernel-i897-k13c-500hz-CWM.zip
Installed 3buttonFix.zip (should let me enter download mode) from recovery, rebooted but still couldn't get in download mode.
Installed speedmod-kernel-i897-k13c-500hz-CWM.zip from recovery. Not sure if I had to do anything special like reformat the filesystem with the new kernel?
After reboot the phone gets stuck on Galaxy S sgh-i897 screen. Got back in recovery and installed captivate-efsbackup.zip and cm7-captivate-initial-20110304.zip
The cm7-captivate-initial-20110304.zip fails when trying to write the modem
'assert failed: write_raw_image("/tmp/modem.bin", "radio")'
I plugged the phone into another computer at that point and was able to get into "Download mode" for the first time. Odin didn't recognize the phone though. Download mode is very flaky. It starts sometimes, sometimes it doesn't (battery charger starts) even on the same port with the same cable. I have tried installing captivate drivers and/or kies on 7 different systems (5 laptops 2 desktops) but Odin never recognizes the phone and windows trows out a "USB Device Not Recognized" msg
I think my usb is not working properly but the guides how to recover assume working Download mode with Odin. Any suggestions on what to do for that? Or I guess I can download a different rom and/or kernel on my sdcard than mount the sdcard through recovery and install that way?
Any advise is appreciated as I'm not very familiar with the kernel and rom differences for captivate

Well you messed up on the instructions but that is a separate point.
I went through your post quickly so if I am saying something you grave tried I apologize
What drivers are you installing
Have you tried multiple ports
Are you using oem cord
Have you restarted your computer
Have you ever used odin before
CM7

I have used the following drivers:
SGH-i897_Captivate_USB_Drivers_5_02_0_2.zip
SAMSUNG_USB_Driver_for_Mobile_Phones_x86.exe (just the usb modem driver)
2 different versions of samsung kies which include usb drivers (don't have the software versions handy but I can get them if that will help)
Ports:
Multiple computer and multiple ports. Will try few more options
Cables:
Used 3 different usb cables. 1 of them is from a BB phone. 1 of the other 2 is the one which came with the captivate (not 100% sure though)
Reboots:
4 of the 7 computers I tried on were rebooted. One version of kies requires this anyhow.
Odin:
Haven't used Odin at all. I think when the phone gets connected and odin recognizes it one of the top left blocks changes color right ? I tried to flash even when it didn't (just to make sure I wasn't missing something) and saw 0 successful / 0 failed

Do you have android sdk installed on any of the computers?
CM7

So many red flags that something wasn't right with your phone and you still tried to flash it? I just don't get it.

@Miami_Son: Yeah but i'm too thick headed - living dangerously but yeah you're right.
@mcord11758: I have android sdk installed on my linux build at home. I'll put it on a windows system at work and see if it can see the phone. Anything in particular I should do / look out for ?

At least you've got a good attitude.

I think if you have kies installed it conflicts with the samsung drivers odin uses. Try uninstalling them and flash odin.

Try this first
Sdk to install updated drivers if this fails
CM7

I've done almost the exact same thing...having the same issues. Phone would not connect to computer. Other captivates connect fine. The phone is now stuck on a boot screen and I can put it into download mode but Odin or the computer will not detect it at all. I don't think I can get into recovery mode, nor can I get into a rom...pretty much just download mode or a boot screen.

@1tontomato: Tried uninstall kies, reboot, install samsung usb drivers, reboot still don't see the phone connected in odin
@mcord11758 The sdk is trying to download the repository directly and I'm behidn a proxy server at work. I'll update tonight, it will be most likely very late by the time I get home.
@kwhee07 Yeah sux to see a download mode but not being able to download. I can get at least into recovery so I guess I can at least flash something that way. The ports really make difference, I've seen many would just charge the phone and some will get your phone into download mode at least. Try a different pc and cable if you can.

I have the sdk...I've tried about everything else I can find. Is there a possible method of fixing this via the SDK? I feel like if I could make the computer force [odins] data out the usb port, it would work, the phone would be in download mode awaiting data....but I cant get odin to see it

There is a package you can install in sdk for usb drivers. Dl it
Open odin
Get into dl mode
Unknown device pops up
Click on it
choose custom drivers
Navigate to c drive/program files/android/extras/google add ons/usb click ok (the path may be slightly different) the computer should try to install the correct drivers
If it works odin should now recognize your device. If not I got nothing
CM7

Got the USB drivers from the SDK and tried to force them when it sees an unknown device, but I get "The specified location does not contain information about your hardware"
I tried to force it to use the samsung drivers also but without success.
Is it possible to just download a rom or kernel and update my current state? So that the phone at least boots. I can install stuff through recovery. Download mode is nice and everything but I'm giving up on it, don't have any more ideas to try
I have been trying to see data on my sdcard from ClockworkMod Recovery 2.5.1.0 I go to
Mounts and Storage -> mount /mnt/sdcard
Install *.zip from sdcard -> choose zip from sdcard
I don't see /mnt at all I try and go under sd/ but it says No files found.

Under mounts and storage do you see the option for mount usb this might be able to force your computer to see it as a removable drive. If out does you should be able to copy another rom to the sd and flash. This may or may not work for you because you might still need to repartition which you only do with odin. Take this advise with extreme caution I really think you need odin If you do decide to flash another rom, use cognition because Dg's includes the fixed boot.bin. Probably because so many people use the one click and kill their button combos and don't know it. Other devs don't include it in their roms, because it's dangerous to over write something that doesn't need to be overwritten. Good luck

I tried already the usb mount option from recovery at home and now at work also on few different systems/ports including a linux machine. I don't see the drive connected.
My only option left is to get somehow the sdcard mounted and install a rom from there. Or maybe just repartitioning/changing the filesystem might fix the getting stuck problem.

I ended up bringing my phone back to att, and they said that the 1010 batch was under product advisory..they exchanged my phone with almost no questions asked.
Now i have a 1008 and am running CM7

Finishing up the story in case it might help somebody in the feature.
I called AT&T to get my phone replaced and it turns out it has liquid dmg. There's a little white sticky that turns red when there's liquid dmg. Mine was pink but wasn't wait so no warranty for me. Turns out most of the time people get liquid dmg is if they leave the phone in the bathroom or close to the kitchen's sink, which is kinda bs but whatever.
I've tried few more times. Tried even on a Mac and on a Linux system (using http://forum.xda-developers.com/showthread.php?t=755265 )
I was about to give up and go seek one of the 'professional rooters' but last thing I tried was to use an 'air duster' and clean the usb port on my phone. After that Odin was able to see my phone. The connection was dropping on/off but it successfully finished a flash.
Not sure if I should even try to put another rom or the official froyo update but at least for now I'm up and running
Thanks all

[Resolved] Can't access device via Heimdall

Hello all,
The past day or so I have been attempting to install a fresh custom rom on my vzw tablet. I presently have a stock copy of DJ11 that is rooted installed.
When I put the device into download mode and connect to the computer, Heimdall (version 1.1.1) gives me the following error
Failed to access device. Error: -12
I have tried reinstalling the drivers, both off of the tablet and from the ZAdiag program included with Heimdall and the error persists. I have tried many different combinations of opening/closing heimdall/disconnecting and reconnecting the tablet while in download and out of download, and I have tried on two different PCs. Nothing seems to fix the problem.
I have seen another post on the forums about this particular issue, but the method of resolution that user was able to make work has not worked for me.
It seems to me that the tablet itself is to blame, like it is locking Heimdall out.
Basically at this point, any rom that requires use of Heimdall to install is not going to work. I do have CWM3 and the Verizon Bootstrapper installed, so if anyone has a link to a completely stock copy of the rom that comes in a zip, please link it as I would like to try that method of installing a new rom.
Thank you for any insight at all!!

Have you checked with odin to make sure the tablet is not connecting?
I had the same problem and pluged the device in another usb port, then hold power, volume down e home and after a while odin showed the yellow bar.
then disconnected it and put in another usb port, after that heimdall found it.
and to mention my tablet was dead, no screen no donwload mode, and not responding to button press. and still i was able to connect and ressurect it doing this.

Thanks for the good idea! When I connect it with Odin open, I get the yellow bar. I think that Heimdall is connecting as well, it just isn't being allowed to make any changes. Access denied is my suspicion. I'm not sure what would cause that, or how to correct it.

I am pleased to report that I was able to find a solution. With Odin running, I was getting a yellow bar indicating the device was connected. I ran Heimdall while Odin was still open...and voila, it worked without a hitch.
Thanks again for the assistance. Keep this one tucked away in your memory in case you ever experience something similar!

You can also update the USB drivers through Heimdall like the instructions say.... Might be a safer way than to have ODIN open too...
You just need to downgrade the usb drivers after using Heimdall to use ODIN again...

I had updated the drivers through Heimdall. Both in regular boot mode, and in download mode. Whatever caused the problem, it is seemingly fixed. I just hope it stays that way!

Galaxy TAB P1000 NOT Detecting in ODIN

Hello xda users,
I need HELP !
I have a galaxy tab P1000
currently froyo 2.2
wanted to upgrade to GB
Tried the Odin way from another link on this site (MANUAL updation for galaxy tab(p1000) into 2.3.3 gingerbread ), it failed and the Tab got soft bricked,
somehow managed to unbrick it, now its back to its original fw, but it keeps restarting in a loop until i switchd the damn thing off completely
I have tried to go in download mode to flash but odin doesnt recognise it , tried differnt computers too, no use.
I have gone in recovery mode, hard reset, wipe cache , still when i switch it on, it goes in a reboot loop.
tried to use heimdall. cant get sucess as i might not understand how to use it properly
Please help.
Sincere thanks to you if you can help me get my tab up and running., if not in GB atleast back in froyo.
(PS- i im not worried about my data , and i have not backed up the rom etc before doing any of these)

Try to reinstall or install a usb driver from samsung

tried that before , didnt work
anyway now i managed to get it detected on ODIN and flashed it to GB
Libon

Yeah, happened to me too, nearly had a sh*t my pants when Odin didn't recognise my Tab.
I would recommend -
charge the Tab fully using wall adapter (4 hrs+)
plug it in with Odin open and using USB cable
don't expect Odin to recognise the Tab immediately
check back after 5 mins or so (I don't know, does Odin refresh?)
I was able to restore my Tab from the PC - ! - Marvin screen.
I don't want to go back there again though!

yea dude.. same here
i kept it on charge for a couple of hours and then tried.. bam it conencts..

My Galaxy tab also doesn't connect to usb after cache wiped humber os flash
Thanks in advance guys!..
Earlier I was using Cyanogen mode 10 Custom ROM but has few issues like recognize SD card.
later I flashed to Humber OS caused real problem.
It was clock work recovery installed but my tab tab boots stays on screen humber OS.
It goes to recovery mode, and also to some unknown recovery mode.
Either the way not recognized by computer. I tried all options like heimtal an Odin. No help.
Friends any help, would be highly appreciated.

BUMP
Any solution to this given the fact that usb drivers have been installed?

Are you sure it is recognised by the computer before trying Odin or Heimdall?

4 Reasons Why Odin is Not Detecting Your Android Device:
Reason 1: No drivers installed for your phone
Most of the time Odin is not able to detect your phone, simply because you haven’t installed the drivers for your phone. Normally windows would automatically download the respective drivers for your phone from the internet and install it. But in case it isn’t able to do so, you need to download the drivers from your phone manufacturer’s website.
Reason 2: Inferior quality or damaged USB cable
Odin is very sensitive to low quality or damaged USB cables, which is a major reason why odin will detect your android phone in file transfer mode but fail to detect it in download mode. You might have a genuine USB cable that came with your Android phone but with time its quality will depreciate, which is why you might have to get a new USB cable.
Reason 3: Odin is corrupted
This happened once with a reader on my blog, we tried everything to solve his problem, but in the end using a different version of Odin worked out for him.
Reason 4: USB port is defective
Defective USB ports can also be a reason for Odin not detecting your Android phone. This was a problem faced by one of my readers and plugging the USB cable in another USB port worked out for him.

reason 1: my phone is samsung and it's detected by ODIN, kies and I transfer files from and to my computer without problems. also tried reinstalling just in case but nothing, so I guess this is not the answer for my problem
reason 2: tried with original cable, but as I didn't use the tablet for a long time I also thought it could be the cable, so I asked a friend of mine if he could lend me one cable, but that didn't work. pity. :/
reason 3: tried 3 different versions of ODIN, and in every version my phone (mentioned above) is detected. shame. :S
reason 4: tried the 3 different USB ports in my laptop. two 2.0 USB ports and one 3.0 USB port, so again I doubt this is the reason of my problem.
extra reason: ~~~ maybe it's the OS version ~~~ // this laptop came with windows 8 preinstalled. nothing. then, I updated to win 8.1. again nothing. now I'm running windows 10 and the same, nothing is detected neither by ODIN nor the computer. also tried in 4 different computers running win xp, win 7 and other with win 8.1.
btw, thank you anyway for your apportation; this may help other people, but unfortunately, it's not my case, so can anybody else join me to think about a new reason and a way to solve it? thank you very much :good: :highfive: :fingers-crossed:
~~~~~~~~~~~~ EDIT ~~~~~~~~~~~~
I have continued researching and found a software. it didn't work for me, but maybe it works for other people.
-first, you have to make sure you have java installed on your computer.
-second, extract the oneclick.rar file on an easy-access directory.
-third, put your tab on download mode (while charging icon when tab is turned off, press power + volume down until a yellow triangle appears).
-fourth, click start unsoft-brick and let the magic begin! 8)
note: if a warning error pops up, trust the software and click on resolution center and follow the instructions of one of the three "alternative ways".

[Q] Windows shows 'unknown device' in Download mode..

This is probably getting boring to some people now but i am having a major issue with Odin detecting my phone when it is in Download mode.
Once i connect the phone after loading up Odin and holding the 3 button combo, Windows installs 2 more drivers - USB Device and then Unknown Device. Then nothing, Odin just sits there and no yellow box glows or a COM port showing the phone is connected. I have tried installing Kies originally and using the drivers from that with no success, then i used the standalone driver packages available from softpedia and several other websites with no luck. What i can't understand is, when i connect the phone to my computer in it's normal state it has no problems and allows me to transfer files, access both the internal and external SD but shows as an 'unknown device' in the Device Manager when in Download mode... Why??!!
Somebody please help me!

Stock rom shouldn't have this problem.. you should either uninstall everything related to samsung from your computer and then start again or try connecting to a different PC.. you'll be able to find out whether this problem is just with the single system or not

I always run up Odin, then use the 3 buttons to get to download mode and then connect to USB port.
Sent from my GT-I9000 using XDA

I had the same problem, then I finally got it to work.
Try this:
First off, you may need to try several different versions of Odin. The one I finally got to work on my phone was V1.85. you can find a collection of different versions to download here: http://droidangel.blogspot.com/2011/05/odin-multi-downloader-flasher-program.html
Next, Load up Odin. Plug in you phone to the USB port with phone powered on, remove the battery on the phone. While holding the 3 buttons down (Volume up, down & power) put the battery back in. Wait for the text to start to scroll, let go of the buttons. When it gets to the menu, unplug the USB, then plug back in. The yellow box in Odin should say it's connected. If not you may have to do this a couple of times.
Now this is the part I can't remember...I think what I did from here is chose the recovery option in the menu. Sorry I don't remember exactly what i did, I was a noob when I did it, and I think I got lucky.
I do remember that Odin would not flash it until I finally got to the screen with the picture of the android in the construction hat, or something like that.
Maybe someone with more experience can help with this part.

I had the same problem

The fix is: Use the USB JIG to get into download mode.

Update your PC USB driver for SGS1. Follow the OP on this link:
