Well, you can theoretically take the stock ROM and stock recovery and flash them, and then use bootunlocker to lock your bootloader, and then removing root from within the root app.

U could do that but it still leave the same problem with the USB not able to connect to the device

Well yeah, for that you need some hardware fixing. Go to a service? Or is the phone still in warranty?

Yea It's out of warranty

same problem
Can't connect to pc for adb & file transfers etc, thought it was a faulty usb connector.
Replaced usb port-microphone part, but problem still persists.
Tried everything, factory reset, flash stock zip, different cables, different computers, re installed drivers & 1000 reboots.
Just keep getting the same result, USB device not recognized. code 43.
I did replace the battery not long ago, but put the old one back in and it still does the same thing.
What could the problem be? If i can replace something, what would that be? :silly:

Odin3: keeps saying Removed, Added ..

Hey all,
I am attempting to restore Vibrant back to 2.1 in order to try out Samsung's official 2.2. When I go into Download Mode and plug up to the PC, ODIN detects the phone, but it will randomly give the noise where you unplug something from USB, and ODIN will say removed, then almost immediately say my phone is added again. I'm nervous to try flashing at this point because I don't want that to happen while I'm restoring to 2.1.
I'm running Windows 7 x64. Has anyone had this problem?

Reboot the pc and try a different usb port then make sure odin is open before you plug the phone into the pc.

Tried this as well, no different result.
Windows 7 is saying:
USB device not recognized
Device driver was not successfully installed
Unidentified device: (red x) device unplugged
SAMSUNG Mobile Modem: ready to use
I'm currently using Nero v5 with voodoo lagfix disabled
Sounds like you could have something as simple as a bad or fatigued USB port or cable. I've seen this sort of behavior with USB devices before and it's usually from a port connection making poor or intermittent contact. Whether it's a port on your cable (either end), your phone, or the ports on your PC...hard to say...

Have you tried reinstalling the drivers from Samsung's Vibrant support page?

Yes that was the next thing I did. Same result. Is there an issue with the drivers I'm using because of the ROM I'm running? Do I need different drivers?

That ROM should have no effect on the drivers. Have you tried installing the drivers by updating the kies program? You might have to install the drivers and software first.

Yes sir, Kies is up to date as well, and says unrecognized device (obviously lol).
As an aside, as I keep trying and trying, now windows is telling me a usb device has malfunctioned, and windows does not recognize it.

To rule out a problem with windows have you tried a different usb device on the pc?

Yes, I just plugged my ipod in and am using it as normal. I am also able to use the phone in mass storage mode as well. The problem only seems to occur when the phone is plugged in during download mode.
I think your driver is corrupt. You should uninstall kies and the usb driver, reboot, and reinstall. Stupid question, have you tried a battery pull on the phone?

Ok, I will try that now. I have entered download mode with and without the battery. I will let you know in a few minutes after uninstalling kies and the drivers, and reinstalling the drivers.

When you try odin are you:
1. Opening odin.
2. Selecting the pit and tar files.
3. Putting the phone into download mode.
4. Plugging the phone into the PC.
In that order?

I was opening Odin, putting phone into DL mode, plugging it in, and then messing with the files. When I started the thread this morning it would remove / add constantly, and then it went to not detecting my phone at all and giving me the error message (only in DL mode) once I installed and updated Kies. Reinstalling Samsung drivers now, just rebooted.
Just reinstalled drivers and attempted in the order you provided, and windows is still saying that there was a malfunction with the device.
Can you try a different usb cable?
Kies is still installed right?
Can you use a different pc?
Sent from my SGH-T959 using XDA App
Yes. My sister has the same phone and cable. I'll borrow hers and see if that helps. I appreciate the quick responses, by the way. Thank you very much.
Would the cable only cause it to act up during DL mode and not regular? I can mount normally, etc.
Edit: Odin detects my phone while it's turned on normally. I don't supposed that helps me any.
If there is a bad connection you can have issues.

Cant Access COM Port on CleanGB HELP!!!

I flashed with CleanGB, and it is a phenominal ROM. But i cant access the COM port on my phone. I tried ##8778# and switched back and forth on PDA/USB/MODEM settings, but nothing... does anyone have any ideas? Please and thank you.
Sry. This is on a Sprint EPIC 4G
Same issue.....
Also my screen stays black when I open keyboard so my keyboard is useless.

Have you heard any way to do this? I really dont want to flash back to the sprint ROM, but i will if i need to, i need to change some numbers......
Have you tried reinstalling the drivers on your computer? Different cable? Different USB ports?

I have tried everything on my computer... My wife epic works fine..
I believe toad said something about it being possibly related to canceling a reboot from the power button. It's in the clean gb rom at the end....
I've just been living with it so far... Plugging it in after power down and removing the battery gets it to boot again...

Then a quick Odin to EC05 stock should get it going again, then root and flash. Don't restore any system data.

Not even in download mode huh? You can try restoring an old nandroid to see if that fixes it.

I think you guys have broken phones.
EDIT: Or in the case of your PC not seeing ODIN, something is probably going on with the PC.
ive had the same exact problem you will have to take your sd card and try to install a stock rom from phones cwm recovery or which ever recovery you are running
I have the exact same problem on the exact same rom.
But only on my home PC.
I tried it at work and Odin recognized the com port. Not sure what is changed on my home PC. I dont have to Odin often, and this is the first time I've noticed this.

I've never installed Kies in my life, so I can't comment on it's functionality. nor am I stock...but before I rooted and started flashing, my Rogers S4 was stock.
I used the AT&T drivers to get it to connect in debug or MTP mode. Maybe they will help. You can find them HERE. click downloads or see all downloads and then EXE on the right for the USB Drivers...
still no luck

well I know those drivers work for fact. My Rogers S4 was running VLUAMDJ software...my computer installed some drivers but it didn't work...it never showed up. just like your symptoms. I uninstalled my existing Samsung drivers (which I downloaded when I got my Note 2)...reboot...install those drivers I linked you to, connected phone...detected right away and MTP started working as expected.
so you either have issues with your system (software wise), or it's a faulty cable. I'm going to lean towards the latter first. It's not the first time I've seen that. feel free to try another cable...also if you want...plug your phone in and take a shot of dev mgr and paste it so I can review...or PM me the pic if you prefer....
I thought kies had a troubleshooting mode. Have you tried that? It is referenced I the noob rooting video.
Here is pic for my dev mngr, I tried 3 usb cable, kies troubleshooting but still not showing up, when I plug my phone kies start-up but does phone does not show up in computer or kies.
Thanks for all reply, I can't send phone to Samsung for repair either because I bought from kijiji and Samsung warranty is not transferable

sorry forgot about the thread, my apologies. I haven't been using tapatalk as much recently, and that's where I used to check my participated threads.
I don't have those devices under ports if I have usb debugging on or off...weird. I'm on win8 x64...the only thing I didn't expand was Portable devices...I only have the two references in my dev mgr....
can you try uninstalling all the detected devices in dev mgr, and delete the driver from the system when doing so? then disconnect the phone, reboot, install those at&t drivers, then plug the phone in and test?
I want to recommend removing Kies before all of that, but not sure if you used it in the past, where it store the backed up data, etc..if you've never used it then please do uninstall Kies before what I mention above...
let me know.

I've installed those drivers on 3 different windows 7 systems this week and not one has failed to recognize MTP on the device first try...I even soft bricked my device a couple days ago, odin'ed back to VLUAMDJ stock, installed drivers on a win8 system that had never had an Android device plugged into it and wasn't connected to the internet (just installed those at&t drivers from a usb drive)...guess what...worked again..
It shouldn't work so easily for soo many people then not at all for you. I'm baffled at how easily it works for me even, and I've been trying to make it not work. I"m a technician I enjoy trying to break things to see if I can duplicate an issue, and fix it....and I can't duplicate your issue.
either something to with your USB port(s), or drivers (either mobo chipset or usb), or windows installation. if you have usb that are controller by a chipset like Intel then other USB that are another chipset, try on the other "bank" so to speak...you'd have ot know how to look for that if you had it though...or try it on someone elses computer with those at&t drivers. don't connect the phone until you install the drivers.
if it's not usb port(s), drivers, or the windows installation you either have 3 bad micro USB or you have a faulty USB port on your phone. or pocket lint preventing a proper connection (although I've assumed you've looked for that already)...those are the only things left.
Still no luck

S4 isn't detected in download mode

I managed to get my hands on a computer so I can ODIN my s4 from 4.2.2 to 4.4.2. Drivers are installed as well as Kies but once I boot the phone into download mode so I can use ODIN, the phone isn't detected. Any solutions?
Uninstall kies, but keep the drivers. Also try different usb ports. Odin can be finicky

Make sure to use USB 2.0 ports instead of USB 3.0 if possible. Try another cable.
