[Q] How to Flash Vibrant when PC won't recognize it - Vibrant Q&A, Help & Troubleshooting

I have the Samsung vibrant model number sgh t959>firmware version 2.1-update1>Baseband version T959UVJI6>Kernal version 2.6.29>Build number>ECLAIR.UVJI6
So now that you know what I have let me explain what it happening and what I have already tried.
One day my external sd card was there the next it wasn't. Its like my external sd card went bad the phone keeps showing a card with a line through it in the info bar. and when you pull it down it tells you to format it..so i did and after that whenever I plug my phone in any PC it is not recognized. On XP it comes up and says Unrecognized and shows unknown device in device manager...in win7 it simply does nothing when usb is plugged in it beeps on phone,no mount option on phone no screen flickers on win7 NOTHING as you can tell I am very aggravated at this.
What I have tried.
1. Factory Reset...No change
2. Changed USB cables...No Change
3. Downloaded drivers from Samsung and other websites...No Change
4. Swapped External Cards...this took away the card with the line through it on the phone, but still unrecognizable on any pc
5. Downloaded the Kies and started to go thru the process until I had to connect phone to pc...scrap that idea wouldn't connect ugh!
6.Flash the phone OK! um nope when you open ODIN and start the process.I bet you can guess yep Unrecognizable
HOW IN THE HELL AM I SUPPOSE TO FIX THIS IF I CAN'T GET MY PC TO RECOGNIZE IT. I called Samsung they said send it to us we will reflash it ok so someone tell me how they are going to when it won't connect better yet someone please tell me with specific directions how I can do it.

I finally somehow got the freaking pc to recognize my phone and was able to flash to odin3 once that was complete the pc began to recognize the phone again so i then upgraded to froyo 2.2 i did lose my full avatar movie during the process

I think I bricked my phone... again...

So I just received a replacement phone because I bricked my previous one and I think I may have bricked this one as well (because I'm an idiot).
I can't get anything to show up on my screen except the screen that has a phone a yellow triangle with a ! and a computer. They're little icons lined up in the middle of the screen when I try to turn it on.
How this happened:
I upgraded my stock phone to Froyo using Kies and then I tried to flash the KA6+Voodoo firmware that I found at http://forum.xda-developers.com/showthread.php?t=870480 using Heimdall on my mac.
I had put the phone into download mode, selected the zImage and clicked start and it just sat there for a little bit before it said "Failed to receive device info response!"
I didn't know what to do after that so I just tried to restart the phone and I ended up with that error screen that I'm becoming more familiar with than I would like to be...
If anybody can help save my phone I would really appreciate it.
You just need to go through the normal odin steps to go back to stock.
The instructions on how to odin are in this forum.. I'm kinda lazy this morning sorry.
Odin isn't recognizing my phone right now and Windows is saying that it's detecting a "gadget serial" device but can't successfully install drivers for it. Based on some advice I found elsewhere, I'm installing Samsung PC Studio which should contain the drivers for the "gadget serial" device.
Hopefully Odin will work then...
also try a different cable. I know that if I use certain cables odin will not work. I have to use the cable that came with my phone.
Google Galaxy s USB drivers and install those.
And your phone is only bricked if nothing ever comes on. So your still golden. Just use the volume button download mode method and odin to stock.
IT'S WORKING. THank you!
The only problem now is that it's not recognizing my sim card...

Turn off the phone and pull out the sim card. Reinsert the sim card and reboot the phone. It should be recognized.
I just tried that a couple times and it's still not recognizing it.

OMG PANIC! Insert another sim and see if that works. If so, pull the battery for a minute and try again with your sim. If that doesn't work call T-Mo and confess that you broke it.

I'm trying to restore my phone to factory settings using (http://forum.xda-developers.com/showthread.php?t=734475) but once again I've gotten the phone ! computer error. However, this time when I plug the phone into the computer to try to use Odin, it's no longer recognizing that a USB device has been plugged in.
I've been trying different combinations of battery pulls, plugging it in after the phone is on, plugging it in before it's on, etc. and nothing is working.
EDIT: Nevermind, I got it. Ignore me... it case it wasn't clear already, I'm a n00b and have no idea what I'm doing.

[Q] Cant access through USB cable

Recently I updated my firmware to version 2.1 -update1. Prior to the update I could access my phone's memory and SD card via my USB Cord. Ever since I did the suggested update, when I insert the USB cable the phone makes the sound that my PC used to make when it connects to something through USB but my PC does not see my phone and the option to "Mount through USB" no longer comes up on my phone. Has anyone else ran into this problem or know if there is a setting I need to change so I can browse my phone's memory via USB?
Other information that may be needed"

Samsung Vibrant
Model number: SGH-T959
Firmware: 2.1 upgrade1
Kernel Version: 2.6.29
Baseband Version: T959UVKA2
Build number: ECLAIR.UVKA2
If there is some information I haven't posted but is needed to help me diagnose/repair my phone please let me know.
I'll ask the obvious, but you did mount the drives using the pull down shade right? Here's another possibility: do you have a lot of drive letters on your PC? Maybe it is trying to assign an already used drive letter to it, if you are using Windows that is.
Did you reboot after the flash?? Try leaving the phone on and pull the battery.
Sent from my SGH-T959V using XDA App
I do in fact have a lot of drive letters, I have an SD Card reader so it takes several drive letters by itself, I cant try to disable it so I can see if thats the problem.
The drop down shade however, does not have the option to mount it via USB any longer, that's the reason I was thinking the PC no longer sees the phone any longer. As mentioned above, my phone makes the "Da-Doink" sound that my PC should make when you attach anything USB and it used to make that sound before I did this update. I cant even find anything on how to do a hard reset to the phone so I could go back to factory default status of the phone. If anyone knows how to do the factory reset I'm open to that option.
Thanks in advance
I pulled the battery with the power still on, waited 5 seconds before replacing the battery, powered it back up and still having the same problem
Factory data reset is in the settings. Settings>privacy. Try that and if it doesn't work then I would either odin to stock or flash one of the many great 2.2 roms on here.
I would search the forum on how to do that. Look in the Android development section.
Sent from my SGH-T959V using XDA App
Also, you could try reinstall the usb drivers.
Sent from my SPH-D700 using XDA App
Settings>privacy>Factory data reset didn't fix the problem either. I am currently going to look for the drivers so I can try to re-install those, although I don't remember having to install them to begin with. I think my PC installed it on its own once I chose "Mount USB" from the dope down shade. At this time its not recognizing the PC to give me that option in the drop down shade to begin with. If new drivers doesn't solve the problem, do you guys know the link(s) for the 2.2 roms and do they have a "how to" to go by so I don't brick my new phone?
Thanks in advance
Also, You guys have been so very helpful. I know with a certainty, I would have already bricked this thing without all of your helpful suggestions and for not hazing the newbie like I have seen happen on so many other forums. Thank you very much!
Look through the forum for the drivers. Go to the bible in the android development section. I believe that is where I found the drivers.

I found new drivers on Samsung's Web Site, their Program KIES-mini. After installing both drivers and software (Samsung's Kies mini) the program prompts me to connect my mobile phone and my PC never "sees" that my SGH-T959 is connected. The only thing it says on Kies splash screen is "Please connect your mobile phone" and that is with the phone connected. Is the next step flashing the ROM? Or are there more options in the settings tab or some other menu that I need to try first? I would appreciate help with finding a true "Newbie" tutorial that will take me step by step through the flashing process so I have the smallest chance of bricking this brand new phone.
Thanks in advance, and apologies for the prior drunken post lol
i have been having issues with internal/external not mounting to pc for the last few weeks i dunno why but i just started having these issues. i thought at first it was custom kernels not working well with some custom roms but i just found out my sister is having issues mounting to pc as well and her vibrant has no custom roms or kernels on it at all. The only thing i did to her phone was root it to add mobile pc so im thinking it is something more phone related maybe. i dunno
If you turn on usb debugging does the phone show its plugged in to the computer then?
Settings, applications, usb debugging.
Also, not sure if this is on stock or not but there are usb settings there too that tell the phone how to act when plugged into a computer.

Just an update on my issues, as of right now when I connect my SGH-T959 to my PC via USB, the PC recognizes there is something connected and I can choose "Mount USB" in the drop down shade but I still don't see either the phone's internal memory nor the SD card's memory in windows explorer and when I try to access the memory through the phone (Applications>Settings>SD card and phone storage) it says "Unavailable" instead of telling me used and free space on the phone and SD Card. The only thing I did differently was hook the phone up to a different PC I have in the house and everything worked on the other PC just like normal. so I brought it back and I hooked it up to the PC I am having problems with to pin point exactly if the problem is on the PC side or the phone side. So, as it turns out the problem is on the PC side. I am going to try installing different drivers and see if that fixes the problem. Also, I don't know if its relevant but when I run Kies Mini on the PC I am having problems with, the phone says "Connected" on the screen, but on my PC the splash screen for Kies still says "Please connect your mobile phone". Perhaps this information might help someone that knows more about the phone and its software know what the problem is.
Thanks
Yeah. Its sounds like your pc. However, if you can't see the sd on the phone it would make me think its also the phone. does this only happen when you try to plug it into your pc?? I would maybe try different drivers like you said. Not the kies mini drivers. If you go into the bible there is a link for drivers. 32 bit and 64 bit.

connection problem with odin and PC

I have a problem with connection my wife's ACE with ODIN / PC. I'll write you a few facts to help you in helping me.
I've flashed phone and rooted (odin detect it and I could also connect to the computer as mass storage).
Even after uploading the new firmware, I could copy some files to the phone.
And here is the biggest problem ... I do not know what happened but something started to go bad (crash with applications, root disappeared, there was an old version of the firmware - I have no idea as possible ... the phone uses the wife and children ).
I tried to clear the cash and fix permission - and in this operation, the phone has crashed.
I decided to flash it again.
I did all the cleaning and format factory.
And that was the end of my adventure - because when I want flashign, odin does not detect the phone. Phone is not not detected as a computer disk.
After a long time of connection by usb cable, Windows pop me up by standard error "encountered a problem installing your hardware ..." "one of the USB devices connected to the computer improvement may not work ...".
Checked on a desktop and laptop.
On both of these computers my other phone (SGS) works correctly and is detected - using the same cable (so cable and ports and drivers are ok).
Could you help me please?
Kies should install the drivers when you plug it in. But during flashing, you need to close kies.
It's not the issue. Drivers are work correctly because other phone is detected. Kies is close.

The problem started with 2 & 5 .
You probably flashed a new stock firmware , which caused root functionality to disappear .
In number 4 , fix permissions should only be used if a few system apps keeps force closing
In number 6 , factory reset isn't needed unless absolutely necessary
I'd recommend you to go to www.sammobile.com and download the firmware that you were using
Then flash it with ODIN
Emo,
but my only one problem is, that ODIN dosen't detect my ACE. So this is my main issue: what should I do, to reinstitiute a possibillity of detecting phone by odin / PC.

this is your problem. Uninstall your phone in Device Manager and install it properly by downloading the standalone USB driver for S5830. Google for it. This happened to me on Win XP. On Win 7, the native/vanilla USB drivers worked fine.

[Q] WHO's FEELING GENEROUS (ODIN,KIES ISSUES etc)

Hey gang, needing some help in regards to Odin and Kies.
Apologies if this has been answered but ive been all over the net trying to find a soloution and as Princess Leia says, "youre my only hope".
Ok the main issue im facing is ODIN doesnt recognise my phone when connected.
The installed software i have is as follows:
Android version: 2.3.5
Baseband version: I9100XXKI3
Kernel version: 2.6.35.7-I9100XXKI3-CL577579 [email protected]
Build Number: Gingerbread.XXKI3
Now i can put my unit into download mode but ODIN doesnt pick up on it.
I also have a connection issue with Kies not seeing my phone either, although when i connect my unit to my pc (alienware m11xr2) it gives me the option to connect as USB storage..?
What im wondering now is there any soloution to this?
Can i root from the unit directly as i cant get ODIN to see my unit?
Thankyou in advance for any help given to both issues
Uninstall/reinstall Kies on your PC (with a reboot of the PC after each step). Try different USB cables, try different USB ports. When you're using Odin, check Task Manager in Windoze & make sure Kies isn't running/kill it if it is running (Odin & Kies don't play well together tho you need Kies drivers to use Odin).
Try a different PC/different OS if all else fails.
You can't root directly from the phone as far as I'm aware. If you're using Odin 3 v1.85, try Odin 3 v1.3.

Make sure USB debugging is checked under settings. If Odin worked before on your computer, try a different one. Install proper drivers and reconnect your phone to the different computer.
Are you using Windows 7? If yes then you should try installing Samsung Drivers in compatibility mode for Win XP and then go to device manager in PC and under USB Serial Controller dropdown, you'll see "USB Composite Device"(maybe 2)..Just update its driver, after update it should show "Samsung USB composite device".
Do it with phone connected to PC and USB debugging UNCHECKED. I'll post screenshots when i go home.
You can use mobile odin to flash and root. Use Kies Air to get the file onto the phone.
Edit: Disregard you need to be rooted to use the app.

thanks mistah bungle, ill have a go now and ill let you know how i get on
OK, tried all mentioned steps Mistah Bungle and no joy.
Uninstalled Kies,rebooted no change.
Rebooted tied Odin both 1.5 and 1.3 no change.
Rebooted tried all USB ports no change.
When plugging in the USB cables though and watching the laptop install the drivers i noticed that the 1st step was ticked and the 2nd (USB Driver) crossed, this occured on all USB ports on my laptop.
I managed to download the SAMSUNG USB Mobile Driver onto my laptop but still nothing changed.
Also have tried ODIN with USB debugging on and off just to be sure but still no change.
Just for your knowledge, my laptops running win7 64bit, 8GB RAM,icore 7 etc
Just seems strange how ODIN used to work before when flashing my device and suddenly this stops..?
lol thanks...well almost
looking forward to seeing if this helps, awaiting yr screen shots etc
Another PC looks like the only way you're going to get it done in that case. Yes it's strange, as to why, that's anyone's guess.
i am also running windows 7 64 bit and odin works great for me. One thing you can try is see if the phone is being detected under USB in Device manager and if you see it there right click on it and click uninstall and then right click and select scan for hardware changes and it should pick up the drives again. Also try disabling UAC(user account control) reboot then try. Let me know if it works.
...
ok went to Device manager as in picture 1 and deleted Samsung Mobile USB modem, unknown device and GT-I9100.
Then plugged phone back into USB and have now, as in picture 2
Thanks in advance people
Are you following the basics ,
Use the USB cable that came with the phone and only connect to a USB mainboard port .

Tried Clockwork aborts...
What does work right now?? U can boot phone? Access cwm but it reboots?
I had the same issue but very simple to resolve. First thing don't use usb netconnect at the same time when using phone data cable and if u r using front side slots for usb they may conflict with other usb devices drivers ...most commonly with usb netconnect... So use back side slots when phone is in normal mode..... Re- installing and unistalling will not resolve this... And be patience..... Be sure drivers are installed and if installed then no need to uninstalling and reinstalling... 100% it will work

so i have to reboot.
Powers up showing no yellow triangle (yet when in download mode says 3rd custom binary and below samsung official).
powers on,seems to be ok then the voice talk app opens, i try and close and this goes on for minutes,on off,on off, i turn the phones screen off,it comes back on
This unit is very unstable at the moment for example:
The unit again is now not recognised by the USB ports allowing me to mke it seen as an external memory device from unit. ,its deffantly the unit,now that i managed to get root access i was going to transfer odin mobile accross from my pc and lightning 6.1 tar, then hopefully reboot,install odin flash lightning and viola problem solved....no such luck.
Voice talk is activating itself now continuesly opening as stated and putting the phone into car mode,just when i think i have 1 problem solved its giving me some thing else to contend with.
i admit im not the most technical at this and need step by step instructions but ive flashed over 50 ROMs/updates on this unit with no issues what so ever, maybe ive just pushed the poor lil bastard too hard for too long (since the day i got it, its been flashed) and possibly its getting revenge because it knows its just a matter of time until i get the SG3...?
I have the will and the patience to want to win this battle im having as i love the phone, but maybe the day is coming where phone meets wall,lol?
anybody?
OK managed to bluetooth ODIN mobile and lightning 6.1 tar onto the unit, hopefully have just flashed the phone....fingers crossed...
Well thats killed it, now unit is stuck on Samsung Galaxy s2 screen and wont boot up.

[Q] Has my SII's USB died?

Well, the day before it occurred to me that I'd like to install a custom ROM, therefore I went on to plug my phone into my PC and for my surprise, the phone didn't pop that MTP warning and the PC did not recognize it.
So I went around and changed USB ports, cables and PCs, same thing.
Decided to try Mass Storage mode, when I press the START button and put in the cable it goes back into the main start screen.
So I went on and tried that *#7284# trick people used since apparently 4.0.3 bugged some crap stuff in the phone, no success either.
Strangely enough I can connect the "pendrive dongle" and it will map pendrives.
Well, I don't have my phone rooted or with SU so that means CWM from app store won't be able to install the recovery module, and I can't install... you get the picture.
Nor ODIN nor HEIMDALL will recognize my phone in recovery mode, wich suggests that the data lanes on my phone went somewhat dead.
Finally, any cable I plug in the phone says it's charging my device, wich leads me to belive that the usb port is dead.
Anyone had this issue?
Anyone can confirm me I'll have to take it to Sammy's assistance?
Sure looks like the USB is dead/dying.
Sent from my digital submersible hovercraft.
So I got one more question, can I root and/or install CWM so I do not stay dependent of the USB to update it or I do need to plug in the USB to install CWM through ODIN?
Several problems
It can be several reasons
1.the usb is dead buy new
2. try factory resetting the device
3. install kies on pc it will install all the drivers that you need
4.your usb port(of the phone) is dead
I had the same problem pc was saying "USB cannot be recognized" I TRIED EVERYTHING from factory resetting, changing pc usb ports, changing usb, changing kernel, roms, trying on other pc, reinstalling kies and drivers but nothing. The problem was in the usb port on the phone where you connect the charger on the phone. That part is weak and so you have to change it. Take to customer service with your warranty and they will fix it without charging anything just tell them your problem and say that you read that most of the galaxy s2 users have this problem and that you didn't touch the hardware of the phone

Warranty has already expired.
Kies was installed on the PC, ODIN gives no info @ COM port.
I wanted to connect it just to root and install CWM so I can swap ROMs as much as I want.
Thing is, the customer service wants 1 week to assess the issue and probably 100USD to fix it.
So for some god-knows-why reason my phone decided to conect to MTP while charging, I quickly restarted it into revocery mode and flashed CF_Root w/ CWM5.5.
Successful!
Bloody USB thingy!
Now I can start messing around with the phone.
Anyone has a n00blet guide on ROMs?
I was thinking about moving to CM 10.1, one of those nightlies running 4.2.2.
This is the one I used >> CF-Root-SGS2_XW_OXX_LPE-v5.5-CWM5
Can anyone suggest actions?
For future you should change your USB-Port. Here we get one for about 15 € (about 20 $) in ebay. It's very simple to change and then you have a full working phone again. Just watch the Videos on Youtube and everyone can do this. Hope I could help!
