[Q] Computer won't recognize my SGS2; how do I return to stock?

I can't get USB mounting to work on my linux PC, windows PC, or work windows laptop.
The computer completely fails to recognize the phone, even when I manually tell it to connect as usb storage device.
I've tried three different USB cables.
ODIN mode isn't recognized either, no USB devices are detected and Odin does not display an ID for the phone.
So WTF do I do know? I believe I need to return to stock firmware but I don't know how without using Odin.

You need to download the drivers for your computer in order for it to read your device. I believe its somewhere here in the forums if not Google it. I would post a link but I'm not on my computer

You can download the drivers from the how to root thread in the dev section.

Are you using the original samsung cable? Mine refuses to be recognized by my pc's if it's not the original cable, works fine with the original but the system never picks it up with any others.

I was using the provided Samsung cable, I have installed the USB drivers.

Did you try installing Kies SW from the Samsung site? Installing this SW will also install all of the appropriate drivers on your PC.

[Q] USB connection not working

Hi,
All of a sudden my gio decided not to support USB anymore.
When I connect it, no mass storage thing appears on the phone, and in windows (windows 8 and 7) there are no signs of any device being connected either.
Even ODIN doesn't find it when it's in download mode, although I do have the drivers from sammobile installed.
Except for this the phone is operating normal, and it still charches propperly (which goes through USB too ).
Any ideas? I don't really need the USB connectivity right now, but in case I want to flash back to a stock rom I do need ODIN to work.
Thanks in advance,
Stannieman

Have you covered the basics yet (try another cable, try on another pc etc). Seems to me like a faulty cable or faulty usb port, either on phone side, either on pc side.

My external hdd works with the same cable on the same pc and same usb port. I have tried all ports. Mass storage also doesn't work on a macbook pro, though I don't know for sure if it is supported on OS X but I suppose it should work. Different cable doesn't work either.
It's not the cable and not the pc.
So I think in the luckiest case it's the connector in the phone?
Friday I'll open it, there's some annoying piece of dust on my screen also so I can take that out too + check for the connector.

In this case, yes, you may be right about the phone's port; remember, even if it's somehow flawed, it could still charge - maybe only the data pins are the problem. Hopefully, it will be only some dust blocking the connection, and not something worse...
Good luck!

If the connector is detached from the board then it's also doable (very careful of course), otherwise it won't ever work anymore.
I can't take it to the shop you see, I can't flash a stock rom...

Try trough cwm--->mount & storage -----> mount usb

Thanks, but doesn't work.
I've had problems with charging one day, but after an hour of trying (unplugging and replugging) the cable it started charging again. Never had charge problems after that.
Actually, I don't know if data ever worked after that. Now I think about it I never tried data connection since then.
Usually when I flash a new custom rom I always flash the latest stock to have latest baseband and other things that aren't changed by the custom rom install (I like having the newest ). That's the only thing I use usb for (and photo's but not anymore with cm9 without preview).
I think it's the usb connector from the phone.

stannieman go to the shop where you bought it and ask if they can look at it

I returned home yesterday and tried connecting to the desktop. Guess what?... it worked.
I don't understand why, as the hardware of my notebook didn't change and it always worked. I tried windows 8 rp and windows 7 (windows 7 used to work for sure), but nothing on my notebook. On the desktop it works just fine with windows 8 cp.
So I think we can conclude that either it's my notebook + macbooks don't work together with android, or that our desktop has magical powers.

PC Not Recognizing Note 2 via USB

I have tried uninstalling and reinstalling the samsung drivers at least 4 times, rebooted phone and pc multiple times, tried 3 different PCs and still nothing.
Nothing(other than charging) pops up on the PC's or the phone when I plug it in. I have tried checking USB debugging several times.
Any ideas?

This just started happening to me today as well haha
Can't figure out why either

Did you get the current drivers from Samsung's site?
How about flashing any recent changes on the phones?
Does it indicate anything on the phone?
Any info - no matter how trivial it may seem - would help. Thanks!

I just got it to work by using the OEM usb cable that came with the NOTE 2.
Previously, I had tried 2 different htc cables, an LG cable and a random generic one. Really odd that it was the cable.

It was this way with the E4GT as well. Explanation I was given at the time was that the pin connections are longer on Samsung than most. That's why most cables except Samsung and BB cables fail on data but fine on power.

I've used the same cable the entire time. It's still not recognizing it.

Yeah it's the one that came with the phone. I tried another cable and still doesn't work. I don't know what changed with my phone. I've done nothing notable to it.

Please post all questions in Q&A

Right click the usb icon in the task bar and find your phone in the devices. Then trouble shoot it. I have to do this just about every single time I want to connect and transfer something.

similar issue
hey guys am new here so sorry for my first post being a problem
ok so im kinda new to the android scene after many years of apple products i can safely say i wont be returning lol very impressed and gutted i didnt switch to android a long time ago...
anyway the problem i have is that after doing a lot of reading and browsing this forum i installed a few different kernels and then started with roms, and now discovered neither Bluetooth or usb works Ive tried many different things including restoring back to stock rom and kernel rebooting several times both PC and phone, ive tried a few other things that seemed to fix for others i installed the drivers at least 9 times now and kies over and over, also tried the galaxy note tool kit but it just wont see the phone it just charges it ive also tried a different cable and the same problem is there... the only option ive not tried is to completely remove root and start again, but the problem i have is that if that doesn't fix it is that i wont be able to root again through odin,
Ive enabled usb debugging etc also nothing im really lost with this now as want to transfer files that's when i realized Bluetooth wont switch on either
i upgraded to 4.1.2 with the omega rom also and still the same now am back to 4.1.1 through a saved restore
so pls any advice or pointers would be amazing

Error is on the phone or PC? And what cable are you using? It should be the stock white cable - even the S2 cable doesn't work for me.

This is correct. I rooted a Note II last night using the white cable. The easiest way is to enable us debugging on the phone and issue the command from your:
adb reboot download
Once it is in download mode you can push your md5 with Odin

Indeed. I did try using a Nexus 7 usb cable and wouldn't recognize my phone but only to charge it not as a usb device. I then plugged another cable that it came with a spare S3 that I have and that worked for me.

i think it shoud be *#7284#

usb/mtp/ptp
I have CM12.1 on SPH-L900, when I go to settings>storage and click USB computer connection, it says USB is disconnected, I don't get the MTP/PTP menu.
I've tried in debug mode, I've tried *#7284#, and many others but none bring up a phone util screen. any help would be, helpful. :laugh:
I used CWM to install.
edit: so I grabbed every cable I had and one worked, happened to be for a kodiak camera.

USB OTG cable not detected

I have been using my OTG cable for a couple of months now. I normally use it to connect my s3 to my usb speakers which worked flawlessly. One day I was listening to music using my usb speakers and suddenly it stops working. Ever since then, whenever I plug my OTG cable to any usb device, nothing happens. Any ideas on what may have happened and how may I resolve this issue?

First thing I would do is to try a different OTG usb cable or usb extension cable , or try the existing usb cable with a different phone.
The phone does not need to be the same make or model.
Good luck!

Thanks for the advice. I've tried 2 different OTG cables with no luck. It's gotta be the phone because I plugged in my brother's Note II and audio was working fine with the usb speakers. Any other ideas?

You can also try this:
Get a contact enhancing agent like Deoxit! or Cramolin and put a tiny dab on the contacts of the cable and insert and remove the cable in the USB socket. DO NOT FLOOD THE CONNECTOR! a tiny amount works better. On the Cramolin label says the less you use the better it works... that should help you get it working. Sometimes pocket lint gets in that connector and makes it hard to get working. A can of "canned Air" would not hurt using it in the contact area of both the plug and socket. It'd also help getting the fluids into the plug before reinserting into the socket.
Good luck
P.S.
you can get the stuff from ebay, and cramolin frrom ebay... Cramolin is or at least was cheaper, but I think Deoxit! works better.

Uninstall all the Samsung USB Drivers and Uninstall KIES if you have that installed then reboot the computer.
Then Install the newest Samsung USB drivers which can be found here: http://androidfilehost.com/?fid=22962010882834451
Be sure that the phone is unplugged from the computer when installing the new Samsung USB drivers.
After the new usb drivers are installed try the ODIN flash again.
It should work.

If it doesn't work on any device, bad cable. Probably needs replacement.
