[Q] Galaxy Tab Issue

Not sure when it began but I am unable to connect my tab to any pc. I have tried 4 different ones. It just gives me the error message "usb device not recognized". I have the custom rom from overcome(the latest one) installed. I put the tab in download mode and the same issue remains. I turned on/off usb debugging and it still doesnt work. I even tried the *#7284#. That did not help either. Please help.

Hi..firstly, welcome to XDA Samsung Tablet Forum. I see you already register since Nov 10 but your post so far is only 2 post. So I'm consider you are still newbie (same like me
Anyway, back to your question.
Have you go to samsung webpage and download the kies?
http://www.samsung.com/my/support/d...WDXME&prd_mdl_name=GT-P1000&srchword=GT-P1000
Do that first, after install it, go to >>Tools>>Install driver. Click it.
make sure your tab is connected to your PC via USB.
After you click the install driver, kies will download the driver for you and it will automatically detect your USB tab.
please try.

Is your pc windows xp or 7? W7 doesnt need any drivers installed, but W xp needs drivers.

Sounds like a fault with windows. Try running updates or use a registry cleaner/fixer see if that helps.
CCleaner has one.
[EDIT] Ah I misread, looks like you have tried other systems with same issue. Not sure then.

I'm assuming you're not using the same cable with all of them, otherwise you'd want to try a different cable. If you've tried the different cables between the different devices and still the same issue, you might roll one of them back to stock and see if that fixes the issue or not. It's possible you have bad usb ports, but more than likely it's a software issue on the tab.

They all are windows xp computers. It was working fine up until a few days ago. Then it just stopped working. Im trying to flash back to stock rom just incase some software went haywire but I can't bec odin doesn't recognize my tab

Have you tried a different USB port?
I had the same problem with Odin/Kies. Updated Kies to latest version and reinstalled drivers and works now

How about the usb cable? Possibility is high due to cable itself. Since you using the same cable with all PC. You should try to change it.

Bad cable or bad tab. Borrow a cable to eliminate that.

Not sure, When i was reading instruction for how to update with overcome rom it said that if Odin doesnt recognise the tab try a different USB port.

[Q] Galaxy Ace s5830 does not detect USB

I have a Galaxy Ace here. When I connect my USB cable to the phone from the computer, the phone starts charging BUT doesn't recognise it's connected to the computer. (i.e. the USB connected does NOT show in the android notification bar.)
I have tried
power on/off,
cable unplug on both ends,
other computers,
factory reset 2 times
etc.
and all ended with the same result.
Seems like this is a problem with the phone. Any way I can fix this?

I just used it a while ago to transfer some music files like an SD card WITHOUT installing Kies..... it worked.
Now suddenly it's not showing the "USB Connected" notification in the Notification Bar anymore.

There's nothing wrong with enabling usb debugging so I don't understand the exclamation.
To OP, what is your rom? For bugs like that i'll normally wipe caches.

What's the ROM that you're using ?

u didnt stated anywhere (until ur 6th post) that ur using linux. its a big difference u know. atleast if we know that ur using linux we wouldnt suggest installing kies. i think its just a missing driver problem. what distro ur using? btw my ace detected just fine on my fedora core 15 out of the box.

i don't think it actually has ANYTHING to do with the OS on my computer.
I have a linux and i have a MAC. Just one or two hours ago i used Simple USB plugging (by pressing on the USB Connected Notification that pops up on the phone's notification area) WITHOUT ANY INSTALLATION OF KIES, and I performed data transfer of music files and picture files in and out of the device... i have done that with BOTH the Mac and the Linux just an hour ago without installing Kies.
However, now the phone would not show the USB Connected notification on my android device when i plug in the USB...... neither in the Mac nor in the Linux. My phone is charging....... but my phone is not understanding that a bloody DATA cable is plugged in and it is connected with a PC (or a MAC or a Linux)
This should not be an issue of the computer OS...... neither be an issue of Kies since i DID do all these without kies just an hour ago in both the Mac and the linux. You do not require Kies for using your samsung phone simply as a SD card.

Don't always come to the conclusion that it has nothing to do with the OS , because in technical stuff anything is possible .

[Q] computer can't see Galaxy S

my samsung galaxy s is not recognized by my computer no matter what i do!
don't know why, i've done some research, no results.
i've installed Kies, which i assume already installs the drivers, but when i connect, the computer shows no sign of connection (it says that i need to update drivers in device manager??) i tried different USB ports, toggled USB debugging on/off, NOTHING WORKS
the reason i want my computer to recognize the galaxy is because i want to update it to android 2.3.5 via odin. but when i enter download mode, the computer doesn't recognize it. when i'm in the system, the computer STILL doesn't recognize it...???
please somebody help, it's rooted, running a different MIUI version (not the ones in xda dev section), i'm not sure where i got it from, but it's called an ENG_MIUI?

CM7 (and subsequently MIUI) is built from the Nexus S source code, so find the proprer drivers for it. "CM7 drivers" should be a sufficient google search. Also, Kies sometimes interferes while using the other drivers. If you run into any problems, uninstall Kies.

To get your phone recognized you need nexus s drivers. But that won't help you get it recognized by kies.
You need stock firmware on your phone to get it updated through kies.

I have same problem previously. But it solved after I do this: while Kies open, select Tools then press Install driver.

thanks guys, but how would i go about doing that? the directions i found don't make any sense?

Just to clarify, this won't help you. Samsung uses Samsung drivers. Since you do not currently have Samsung firmware on your phone, this won't do you any good. As previously stated by two very informative posters, you will need the Nexus S drivers to recognize your phone.
And, also as previously stated by just an absolutely wonderfully helpful poster, if you do a simple google search you'll find exactly what you need. Try either Nexus S Driver, CM7 Driver, Nexus S CM7 Driver, or really anything else similar. You could also check the CM7 Wiki, as I'm sure there would be a link for them there. And finally, if you simply search XDA Developers, I'm sure you'd find plenty of posts with what you need.
Hopefully that helps.

thanks
now my computer can see it when it's in android, but why does it STILL not see my Galaxy S in download mode???
do i need another set of drivers? (it said driver not found)
BTW THANKS GUYS!!! sorry if i'm being annoying

hello??
anybody??

Well did you install the Nexus S drivers yet?

Well, it seems to be a driver issue!
Try these (32-bit windows) but make sure that you are having a fresh win7 installed just in any case that your reg got corrupted with drivers (Ime ).
Still not working,then try on another pc..!

Well, CM7 drivers won't help SGS to get recognized on PC on DLD mode, you need another set of drivers and not those Nexus S's. I had the above ones installed on my PC (Google's your Best friend ) .

I had to install the drivers manually,
Right click on computer, click manage -> device something -> find your device in the list, select to update driver, search manually and enter the path to your android sdk and search.
Worked like a charm to me

hi
i had same problem, but computer recognize the device as "unknown device"
in all modes, developed, storage etc...
i am close to think thats is problem of internal usb driver of the rom
want to downgrade from de device, whitout usb, but i dont know how do it, because i am not root, and its no possible in 2.3.4 whituot usb.
thanks

I had a lot of similar issues with my I9000, too.
Tried everything on ROM and driver side also on different computers.
Finally it turned out that my Micro USB connector was corroded.
I have around 30 people in our company that have the same phone, and 5 of them had similar issues. I guess it's a common problem with this device.
I took a toothpick and cleaned the contact of the connector by sliding it up and down for a couple of million times. This also did the trick for my colleagues.
I think it's at least worth to try it.
Good luck

i try to clean the contact, but still cant connect to the computer.
I wonder if a method of degrading the system with a signed rom from the recovery, without using the USB cable or ODIN.

i have a same problem. Any new solution?

[Q]

Well, my problem is that my phone won't recognize any computer as a computer, but only as a source for battery charging. when i plug it into a computer the battery starts charging but i don't get the USB sign.
the thing is that it used to work. i usually just pluged the phone in and it would work, and suddenly out of the blue it stopped working and i have no idea why. i've done nothing on the computer between the last time it worked and the time it stopped working, i wasn't even using the computer during that time, so it must be something on the phone settings, but i checked it a little and found nothing that looks like the problem, but i rly don't understand much about it..
any ideas?

It sounds like a driver issue.
If you're using a Samsung firmware, reinstall the drivers. This can be done by finding them online, or by installing Kies. If you're using CM7/Miui, Samsung drivers won't work. You'll need to uninstall Kies (or kill the process to make sure it's not running in Task Manager) and then install the Nexus S drivers. Again, a simple search will provide the files you need.
If it's not a driver issue, I really don't know what it could be. But I would definitely try reinstalling the appropriate drivers first.

Go to Settings>Applications>Development and if USB debbugging is flagged,deflag it!

Try to reinstall Kies or one of the steps that I've read here:
http://www.androidgalaxys.net/suite...problemi-connessione-collegamento-usb-galaxy/
Translated:
Make sure you have installed the latest version of Kies (currently 2.0.1).
For owners of Windows Vista / Seven Kies launch in admin mode
Connect your phone to your PC using the default launcher from Samsung (TouchWiz)​​. Alternative launcher may not be recognized by Kies. Close any programs in the background on your phone and PC.
Make sure that in Settings> Wireless and Networking> USB Settings is selected Samsung Kies or Ask the connection.
If you already selected, try to choose any item and then set one of the two mentioned.
Try using another USB port on PC. Not all USB ports may be able to deliver the power needed to power the device.
Restart both the phone and your PC.
Try reinstalling the drivers of the Galaxy. To do this open Kies, go to the Tools menu and then install drivers.
Try using another USB cable.

ok, I tried everything but switching cable coz i know it works...
here's the weird thing: I tried connecting my phone to 3 different computers, 1 worked and the other 2 (including mine) didn't work.
the thing is that the other computer that didn't work and the computer that did work never touched a Samsung before, so basicaly i have no idea what would make one of them work and the other not to work.
I'm really confused.

Try going into device manager and see if there are any devices flagged with '!'
If not, find your samsung device from device manager, and uninstall it and delete all drivers, then reinstall them.
Try that. It may just be a windows issue, I've had similar problems before but not even with a phone, but a flash drive.

well, tonight the computer restarted itself because of some updates, now it seems to magicaly work, even though i restarted it before.
i have no idea y it suddenly started working, but i can only hope it wouldn't happen again.
thank you all, you guys are great!

[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.

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.

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?

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.
