[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.

Thanks for all the help everyone.
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] peoblems with odin and usb connection

ok i am new to the scene. i had my brother in-law "whom told me he knew how to root it" ok he failed i got my phone back and when i turn it on i get a splash screen that has the samsung galaxy 2 logo a triangle with a exlamation point and says GT-I9100. ok i did some search and found out this is wrong very wrong. so i attempted to get to odin to try to recover what i could. i was unable to access odin so i built the micro usb jtag jig and i am know able to get to odin, but when i plug my phone into my pc thru its usb connection my pc doesnt detect,see, or even regonize my phone can some one please help me

If you are technical enough to build a jtag jig then you can figure out how to root this phone. I dont want to sound like an ass but there are guides and links everywhere here. Also check out qbking77 on youtube and look into an app called triangle away.

ok that is a smart ass reply. first of all if you could see my net history you would see that i have read and tried all that i could.
1. the wrong os for a different carrier was put on the phone
2. i can access odin
3. if you read my post i stated that after i get to odin and plug the phone into the pc the pc CAN NOT EVEN SEE THE PHONE.
4. I have tried all that i can locate and i have not been able to locate any post that are like mine
instead of being an ass and leaving a smart ass remark how about actually helping.
as for making a jtag jig and its relevance to rooting a phone is idiotic since all i did was follow instructions on it

If your phone has the wrong os for a different carrier it would be a brick right now.
Are you saying the phone doesn't boot or do you just have a yellow triangle and usb issues but your phone works?
Did you even load the samsung usb drivers?

mental yedctve
ok here is a pic of what my phones start up screen looks like
the phone boots to this image and flashes it twice and then goes black

Your phone is nice shiny brick if
- There is no recovery to boot to.
- Pc doesnt detect phone when in download mode even with different usb cables and you have tried to clean usb port. Oh and pc already has samsung drivers.
I hope someone proves me wrong.

should help.

Sadly I think the OP may have had the international bootloader flashed onto the system. If you could get into the system then you could flash Mobile Odin and get a recovery on that would allow you to flash things except for a modem.
As posted above, please try the following thread first:

[Q] Can I get root w/o USB?

So the short question is if there is any way for me to get root without a working usb port?
Last week I plugged in to charge my phone overnight with the phone off. In the morning, I was surprised to find that the screen was on and what should have been a full green battery was instead a scrambled image that kind of looked like a battery. I powered on the phone and it worked so I thought nothing of it but later on that night I needed to pull a file off my phone via usb and realized that the phone will no longer detect the usb host, ie. no mtp options whatsoever. It at least does still charge.
Since then I have tried cleaning the usb connector, pulling the battery/sim, setting the UART using *#7284#(PDA, mtp+adb), multiple computers, and multiple cables(including the Samsung one) and the phone still doesn't ever think its connected to a host. So today I decided to use my php warranty service which meant I had to restore stock recovery and rom. So I grabbed mobile odin and a stock UVLDJA image. Ran Triangle away once to clear the counter, and another time to verify it was at zero, and installed the full image via mobile Odin. When the phone booted back up, it successfully installed the rom only the flash counter is back at one and now I have lost root. If I had used my head I should have flashed just the recovery first but I wasn't thinking....
Any suggestions on how to get root back? I read these forums quite a bit and I am thinking that I am SOL but hoping maybe someone has a suggestion I haven't seen yet.

Checking your flash counter in TA trips your counter, that's why it's at 1. Use mobile Odin to flash root66 to get rooted again.

Oh, duh! Yes lol you do. There would be no other way. Have you tried a factory reset then try to connect your phone? You could also try to install Kies on your PC to make sure all drivers are correctly installed.
If you wouldn't have said you have tried other cables, I would have for sure thought defective cable. Some cables are also charge only.

Yeah, did the factory reset along with all of the other suggestions I could find. I typically try to avoid Kies and since I cannot even get the device to enumerate I'm pretty sure it's not driver related.
I think my only hope would be getting root or twrp intalled via stock recovery or adb over wifi.
Thanks, I appreciate the help.

download Odin3 v1.85
Put your phone in download mode (vol down=menu=power then after the screen comes up press vol up
plug the phone usb to the computer,
run odin
the first box on the top left should have a colored highlight (the ID:COM )
if that pops up, your phone is 99% functioning correctly, and only problem is in your computer.
When trying do do a regulad usb transfer to the computer:
I have noticed, sometimes I have to connect, wait a bit (like maybe 2 minutes)
then disconnect the cable for about 15 sec then connect again, and it pops up after a minute
you could also try this:
open explorer on the computer(double click on my computer) and see if there is a t999 in your left pane. Sometimes the autorun function in the
computer gets farkled and it does not open automatically and you have to do it manually,
Good luck & Aloha !

Go to galaxys3root.com and follow his t.mobile root tutorial WORD FOR WORD. USE THE USB THE PHONE CAME WITH AND KILL SAMSUNG KIES. also run Odin before you connect the phone to Pc, should be no problem bruh once it took me a couple of hours making love to my comp before I got a colored com box. And use a windows PC Mac suxx for this kind of.

I've basically given up trying to get the usb port working... I am convinced this is a hardware issue. Nothing shows up in the device manager when I plug in the phone whether USB debugging is on/off or I am in normal mode or download mode. The phone will never bring up the MTP options in the notification bar either. Again this is with multiple cables on 2 different comps where it used to work just fine. I think whatever bad charge experience I had last week damaged the USB host controller on the phone.
I think what looks promising now is using adb over wifi(http://forum.xda-developers.com/showthread.php?p=26844535) along with root via adb(http://galaxys3root.com/galaxy-s3-root/how-to-root-u-s-canadian-dual-core-galaxy-s3-on-mac-osx/). I can't do this at work but I'll follow up tonight on what will hopefully be success in case this could help someone else out.
Edit: Ugh, some quick googling shows that I need either root or working USB to make adb over wifi work.

I don't think so.... the micro usb port is mounted on the main board and short of replacing that entire board it would be a ton of time/effort for something that I don't exactly think is the problem.

This happened to me, and it was from using different devices in the same port (with same cable). I switched ports and it worked. Might not work for you, but worth a mention - it really stumped me and I tried everything including restoring the OS to an earlier point.

Now that S3's are getting older, more people will be losing their functional USB ports. I found holding the phone vertically with steady even pressure on the plug was the trick to getting a solid connection on my flaky port, at least enough to get stock back (to send it back). That was the longest 15 minutes of my life (OK, not, but it was in the top 10, mostly because it was simultaneously nerve-wracking and insanely boring).
I tried de-soldering a usb port on a Galaxy S. Yeah.... To say it mildly, the way Samsung sets them up is booby-trapped. You can't get the existing silver solder hot enough to melt without toasting the board somehow. The boards are also wafer-thin and dimensional on both sides. Despite generally having a knack for fine tuning and detail work (thanks to estrogen or something), I felt like an ogre in a doll house. I definitely would suggest having all the (exactly) right tools in place before tackling it. Even then it might not be the port itself, but something between the actual port and the other components.
One other thing to note, Mobile Odin is an amazing tool, but it's even ***more crucial*** than regular Odin to get your ducks in a row before you flash. Know exactly what you are flashing what your next steps are, and what your results are supposed to be. One thing in particular: if you flash a stock ROM, it includes stock recovery, and you will lose root. make sure you've run Triangle Away before you flash stock (which won't trigger your counter, but anything else will).
I plan to keep the Triangle Away and Mobile Odin apk's ready on ExtSD to install, and a copy of a stock image (ROM) as well, from now on, on all my phones. You never know when that port is going to give up the ghost.

Just thought I'd add a couple things here. More times than not, when someone thinks their usb port on the phone is bad, it's actually just the cable. Even if the cable works on something else, or works to charge the phone. They ruin much, much, more easily than anyone wants to believe! Especially when you plug/unplug it as often as with a phone.
As for Mobile Odin, I fully agree! It's one of my favorite apps by far! But if you're going to keep stock firmware handy, which I highly recommend, you may as well keep the root66 version. Flash back with that, then run triangle away, then in SuperSU, choose full unroot. Then all you need is a factory reset. Making TA the last step makes for far fewer user mistakes.

SGH-i747m only boots to recovery mode with 16gb sd card

Hello, I purchased a phone off kijiji fully knowing it was not functional - For the 40 dollars my curiosity got the best of me; and if I can fix it well I can get myself a new phone for cheap. I was informed that this phone: Samsung Galaxy sgh-i747m had the latest update (not custom rom). The phone suddenly would not boot past Samsung logo and by the time I bought it, would not boot up at all. So after doing extensive research I decided I would give the 16gb class 10 sd card boot a chance. While somewhat of a success, the only thing it boots me to is this.
BOOT RECOVERY MODE (IN GREEN)
CHECK BOOT PARTITIONS
COPY FROM T-FLASH
BOOT RECOVERY
WRITE 159488 SECTORS
FLASH WRITE FAILURE (RED)
ODIN MODE (RED)
PRODUCT NAME: SGH-I747M
CUSTOM BINARY DOWNLOAD: NO
CURRENT BINARY: Samsung Official
SYSTEM STATUS: NONE
QUALCOMM SECUREBOOT: ENABLE
Warranty Bit: 0
BOOTLOADER AP SWERV: 1
I should note that with the debrick-SGH-I747M-UEMK5 image that I used, the phone will boot to recovery mode without holding any buttons(While Plugged in). It will also boot to recovery if it is unplugged and I simply hold and release the power button when I feel the vibrate. I have also tried volume down + home + power. Same thing. If I take the sd card out I cannot get any sign of life / no recovery mode.
The computer does not see the device at all, even in device manager as a random name. There are no signs of life on the computer end. ODIN also does not detect it even when in boot recovery mode. Will not boot to download mode. A red light comes on if I pull the battery out and plug in the usb cable.

No, I was contemplating making one or ordering one online but was unsure if that would make any difference. But I am willing to try anything even if there is a slight possibility it could work.

Where are you located? I recall seeing a thread on XDA about people that has a USB job for use by other XDA members.

Will do. Going to build jig today and test it out

Another solution may be to have the firmware flashed via jtag.

You should be able to flash with Odin from there if I'm not mistaken. (Been a long time since I've been through this part myself). You may need to try different drivers, different cables, usb ports, etc.

Yea I didn't want to have to go that route if possible as my goal was to gain experience and knowledge from this little project. If I got the phone working then I would just replace my old Samsung infuse. I made the USB Jig using the 301K ohm's and it still does not work. I know the jig works because I tested it on my wife sgh-i747m and also on my infuse. Both of which boot into download mode immediately. My concern is there is something wrong with the main board because it really doesn't seem like it was rooted at all.
I am just going to see what I can get for it at this point, I paid 70 so would be looking to get at least 60

I have tried 5 different cords, and two different computers on all usb ports. Nothing

You said it'll boot recovery, is it stock or a custom one? Also, are you familiar with ADB?
When you plug it into the computer, is it detected by odin? If so, what does it say in the message box when you try to flash?
Look in device manager too. What does it detect the device as?

Sorry, I have the SGH-i747. The phone only boots with the SD card and just stays in download mode. Odin doesn't recognize it.

What was the last stock ATT ROM on the phone? Can the phone boot into download mode without the external SD card?
When you connect the phone to you computer in download mode, are you prompted to install drivers? If you are using Windows, any unrecognized devices in device manager?

And don't forget to try different cables and every USB port on the computer. Cables go bad much more easily than most people think, and many charging cables cannot be used for data transfer.
I've seen a number of times where people found that only one of the USB ports would allow it to connect.
You might also want to try several different driver versions. (I'd start with the oldest that was release along with the S3.) You can find several in the link in my signature.

Problem with USB Driver

I just got my phone fixed by a repair shop and they had to replace the motherboard. So when I got it back it has 5.0 on it instead of my KitKat ROM I like. I'm trying to get into Odin so I can reflash a stock kitkat rom but no matter what driver I put on my computer when ever I plug my phone in Windows says Unrecognized Device and Odin doesn't pick it up either. Please help!! I am dying without being able to revert back to KitKat and my favorite rom.

Try downloading and installing the newest version of Kies. It will install all the drivers you need. I'll look into that issue in case that doesn't work. Hopefully they didn't install a board with a bad port. It can be bad and still charge.

I don't have Lolipop, but don't you have to manually set USB to connect on the phone (MTP mode), otherwise it stays in charge mode only? either that or your phone is set to charge mode only and you need to enable either MTP or PTP under USB options, for connection to work.

You're correct about MTP for mounting as internal storage, but MTP and PTP isn't used while in download mode and connected to Odin. It uses ADB at that point and it does that automatically. You just have to make sure USB Debugging is turned on.

Just gonna check some things with you. Have you made sure to activate Developer options and turn on USB Debugging? I know it doesn't connect while attached to a computer right now but does it charge? You said you've tried different computers, but have you tried different USB cables as well?
If the phone is charging but not connecting there is a small trick to see if it's a hardware issue. Get a very this piece of plastic or something else kind of stiff and barely wedge it under the charging port. You put it under the lower side that faces the back cover. You only want something that's going to put a tiny bit of pressure there. Most of the time if a charging port goes out, it's because the contacts are loose. If you do this and it connects as it should, then they put a bad board in the phone. This trick should be the last resort though.
