[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.

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

And?? Solve the problem or what? We been hanging here for years

All of a sudden phone will not connect to pc.

Alright I am running cm9 and have been for weeks with no issues. I got the new galaxy s3 and installed the drivers on my pc to root it and all that. I want to change roms on my E4GT though so I go to plug it in and it charges but will not connect so I figured I had to reinstall the usb drivers for my e4gt so I did and still nothing. I am in no way a newb i have flashed tons of roms and I know I did not do anything wrong. I believe I am just missing a driver. Can someone point me in the right direction? I have the latest version of kies installed and the drivers straight from samsungs website.

Made a little progress but not much. I realized I didnt have usb debugging enabled so I enabled that but now when I plug it in it just says usb debugging enabled instead of asking if I want to mount as storage device I have tried rebooting phone and pc several times. I am running out of ideas.

Did you get the drivers by installing Samsung Kies?
I ran into a similar issue once. I removed all Samsung software with all devices disconnected, did a reboot, re-installed a new copy of Kies, and when I plugged in the device, I opened the notification and told it to skip searching Windows Update.
Also, make sure you are plugging it into a powered USB port, so one on the back of your computer. Sometimes laptops don;t provide enough power either. My girlfriend's OG Epic refused to flash on my MacBook Pro, but worked fine on a desktop.
Latest version of Samsung Kies: http://org.downloadcenter.samsung.com/content/SW/201105/20110512115717796/Kies_2.3.2.12054_20_1.exe

Thank you very much i will give it a try and report back.

Actually no i did not get the drivers by installing kies because I already had it i got the sprint sph d710 usb drivers. Should I uninstall those and just install kies?

Well this is a rediculus problem that I am having now.. I cant install kies because it is saying I am not connected to the internet and I clearly am as I am posting this on the same pc that I am trying to install on.. I have tried rebooting the pc that does nothing.

Alright I got kies to install but still the same thing when I plug the phone in it says usb debugging enabled i really have no idea what is going on.

have you tried different ports on your computer, also have you maybe tried a different computer. If not it could be phone issue I fried my usb board on mine. best bet to try that is to flash another rom if possible and see if it you can connect to computer

I have tried different ports but not a different comp. Ya I am gonna flash a new rom and see if that helps. How could I have fried the usb board though? I havent touched the phone in days since I got the gs3.

Yup Just flashed the new Super Nova rom and now everything is working again, thank you very much for all the help and if anyone hasnt checked out that rom yet they need to its awesome!

[Q] USB/Computer connection issue

Hello XDA!
I don't want to post a wall of text (not that tall of a wall, at least), so, I'll try to get to the point quickly. And yes, I have done a lot of searching, both on XDA and Google, and that will be proved soon enough with the solutions that I've tried so far.
The problem I'm currently experiencing is when I connect my phone to my computer, it charges but it isn't recognized. There is no USB notifications, no phone in My Computer, and no Windows pop up, whether it's a pop up asking me to install drivers or an unknown device has been connected, nothing. Mind you, everything has been working flawlessly, this just randomly, and I really do mean randomly, started happening. The phone has never been dropped and there is no water damage. I'm still using the USB cable that came with the phone. And, if it matters, I'm rooted, running the leaked LI8 JB ROM, stock kernel, and UVLEM baseband.
Here's a list of said solutions that I've tried so far:
Using a thin paint brush, wet the tip a little with alcohol and tried cleaning out the USB port
Connecting to a different computer, connecting with a different cable, connecting to any other USB ports on the computer
After making Nandroid backup: Data wipe/factory reset, flashing a different ROM
Remove Samsung USB drivers and reinstalling, also tried installing Samsung Kies
Uncheck USB debugging and restarting, checking USB debugging and restarting
Dialled *#7284#, select Modem, then reselect PDA, changing Qualcomm USB settings and changing it back to MTP + ADB
Turn off phone, remove battery for 30 sec, reinsert and boot up (soft reset to reset internal circuitry as described by a Samsung live chat service tech)
I might've left out a couple, but please do enlighten me of methods that you might know, I'll be sure to try it or let you know if it's already been attempted.
..also, when connected to my PC, under Settings > Battery, it shows "Charging (AC)" IIRC, this should be showing "Charging (USB)".
This next attempt stood out to me. I decided I would try and go back to the stock firmware, one where I would have to use Odin3. So, I put the phone in Download Mode, open up Odin3, connect the phone, and I get a pop up in Windows! It's trying to install drivers, and fails. I can't flash the stock Samsung firmware if I wanted to, even for warranty purposes. I do currently have the USB drivers installed, but my PC hasn't gone through the driver installation for when the phone is connected to the computer. So, I'm assuming that is why this is failing? I'm not entirely sure. But, when I saw this, I unplug the phone and plug it back in numerous times, to rule out that this might be a hardware problem. And, every time I plug it back in, it tries to install the drivers but fails. So, it's detecting my phone in Download Mode. I reboot and hope that it will detect normally, but no, it doesn't...
As a last resort, I went to Samsung.com and chatted with a service tech, he runs me through two procedures that I haven't done, the 'soft reset' and a 'master reset', which is done through Settings > Back up and Reset > Factory Data Reset. Neither worked, so, he then checks my IMEI and finds that I am still under the 1 year warranty and files a ticket for repair service. I asked him if there is a replacement warranty and he says that is done through my service provider (T-Mobile) with the Premium Handset Protection service, which I didn't add. Not because I didn't want to, but I can explain in later posts if someone is interested in why it wasn't added. So, now I have the return label in my inbox ready to be printed, taped onto a box containing my phone, and sent out. But, I can't go through with this because I have a custom ROM on the phone. There is no counter because I've already used Triangle Away, AFTER this started happening.
I am completely stumped... Any information is greatly appreciated!
EDIT: Also, I've disassembled the phone to check the MicroUSB port to see if any pins or prongs might've came loose. Everything is in tact.. I also wanted to see if the MicroUSB port was replaceable because I was able to find a spare MicroUSB ports on a website. But, it seems that the port isn't easily replaceable. It doesn't look removable, and I'm uncertain if it can be de-soldered to solder a replacement one on. Also, some thing caught my eye when I had it disassembled. There were two components of the phone that had SGH-I747 imprinted on them. I wasn't able to take pictures as I was in a rush to get it put back together, but thought it was of interest to bring up.

How do you have a custom ROM if you flashed the stock one? I'm confused..
Try installing drivers through the toolkit.

If windows recognized it in Download Mode, keep trying to unplug and replug the cable in the same and different ports until it installs?
This happened once on my Galaxy S 4G.

Uninstall all related drivers, kies, etc. Restart pc and download and install these drivers. (Should be latest)
http://d-h.st/zya
Or download and install latest version of kies. Drivers included.
Try connecting again.

I was never able to flash the stock firmware because my computer fails to install drivers for it. I've also tried using the drivers from the toolkit and it gave me no results.

I just hopped on right now after trying the different USB ports on my computer while in Download Mode. Same deal, it detects, tries to install drivers, then fails. It's coming up as an Unknown Device.

I currently have the latest Kies installed. I'm going to uninstall and give that link a shot, though. Hopefully, Odin3 will be able to detect it, at least, so I can get the stock firmware back on this thing...

Thank you for your input, but I doubt this would work in my situation. Ive tried connecting it to my laptop and another computer in the house and they both do not detect the phone. However, i would consider going that route as a last resort if there arent any other ideas.. i just need Odin3 to recognize it so i can revert and send it back in..
Any other suggestions, XDA? And thank you to those that responded!

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

Thanks

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.

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.

[Q] USB device not recognized, half rooted, no custom recovery--Totally messed up!

Here is my problem where I can't get my Sprint S3 connected to PC, I am half rooted, and have no custom recovery, I can't flash anything on my phone except OTAs, please help, any help is much much appreciated.
Background :
I had this phone working completely fine, I bought aftermarket USB cable and attached it to the PC, everything went smooth it got connected fine in MTP mode, on second day when I tried to connect it, it gave me error that USB Device Not Recognized.
Problem :
The phone is not getting connected to PC in any way, whether it is MTP, DM+Modem, PTP, ADB, etc... not even in download mode to flash it via Odin. No matter on which mode I am it always give me error that USB Device Not Recognized.
It sense when I change modes while it is connected to PC, like when I am on MTP and I click DM+Modem or I click USB Debugging, it displays that USB Device Not Recognized message again, so I it is sensing mode changes.
What I did so far :
Changed cable and used brand new Samsung Original cable, changed USB ports, changed 4-5 computers, installed and re-installed drivers numerous times, my friend who does the phone repairs changed Micro USB Slot on the phone 4 times with Original ones, he even took one from working phone and put in on this phone, no luck so far.
My inputs :
I've searched really a lot about this problem, but didn't find any single solution.
Some guys on forums reported that they solved problem by flashing a stock or custom rom as there might be a problem with Kernel.
I can't flash anything on my device since I am on stock recovery and half rooted, I had LJ7 rooted stock on my device, and I took MD4 OTA, now, my phone is half rooted, when I install any application which requires root, I get message that 'Superuser permission denied'.
I can't even uninstall Superuser, because it is system app, I tried to re-root phone via Motochopper method but it doesn't work.
I flashed this phone to different carrier, so, I am afraid I will loose my flash if I take latest 4.3 OTA.
PLEASE HELP IF YOU HAVE ANY SOLUTION FOR THIS PROBLEM, I WANT MY PHONE TO GET CONNECTED TO PC ANYHOW.
I AM READY TO DO ANYTHING YOU SUGGEST TO RECOVER MY PHONE.
