Hi, i have a problem with my Samsung G2(SGH-T989), i'm running Win 8
phone shows black screen, no logo no nothing! Phone was rooted prior to all this.
The phone however does install drivers or not i don't know but when i plugged phone via usb it shows as per the pictures below.
Odin (i run as admin) shows com ports, Have tried all different combos (take battery out, hold volume up and down, replace battery, start odin and re-plug via usb etc) but nothing works
ODIN hangs at 'setup connection'
I have downloaded the stock firmware from sammobile (its one package) and added it via the PDA section, even tried the different versions of ODIN. Also tried removing Sim and Sd card.
The phone is getting recognized via device manager but stumped how to get Odin working
Anyone else had this and solved it?
Thanks
First things to try,
Different Odin version... That version you have is old. Try 3.04 or 3.07...they've worked best for me.
Try a different cable. A different USB port. And if needed, a different pc.
You did install the Samsung drivers on the pc?
If kies is running, kill any mention of it in task manager, processes.
It could be a Windows 8 Issue... But I have 7, so don't know.
And try a google search too to see if you find more on this.
Good luck!

thanks for your reply,
sadly, i have tried with different version of odin that you had mention and also tried with different port and cable but all these not working for me.
when i try with odin 3.04 or odin 3.07 it doesn't show com-port highlighted in yellow color as older version(ODIN 1.85) does.
i can't see logo , no nothing in phone and even phone won't vibrating when i start it after removing battery.
help me plz -_-
It's likely bricked. That or the battery is completely dead and not charging.
But, if there's no sign of life as you say, I don't know how Odin and the pc see it at all?
But for Odin to work, you must be in download mode. Or it will never work. But if nothing is happening on the phone, you obviously aren't in download mode.
I think it's toast to be honest.

Hello Everyone,
Captivate owner/user here, but had a question regarding a buddy's Epic. I have looked all over the forums, but have not found anyone else who has encountered this problem, so I apologize if this is a repeat thread. I believe my friend was running BakedSnack v1.6 with the DK28 modem. He went ahead and tried flashing ViperRom Trinity, and got stuck at the Samsung screen. I'm not familiar with flashing on this device, so I dont know the correct methods. I did however try to Odin his phone, and have failed to get my pc/odin to recognize his phone. I've tried every driver file I could find and nothing works. He has access to CWM so I hope it's not fully bricked. I figured his pc would recognize it, having has the drivers previously installed, but nothing. Any feedback is greatly appreciated, thanks.
Try a different cable and a different USB port on the computer. These phones can be picky with the cables.
You are not bricked if you can get to CWM.

Originally, we kept trying on my Captivate's cable to no luck. My pc would not even beep or see it. Then we tried another micro usb cable, and this time my pc saw it, but couldnt identify it, due to drivers im assuming. That was as close as I got unfortunately...

Tried that driver already, still no luck. At first i was thinking my pc wasn't installing the driver correctly until he installed it on his computer and had no luck as well. I installed it multiple times and uninstalled it, still never recognized the phone.
might want to install the android sdk, i actually remember having issues as well on my win7 pc until i did that. then look for adb in C:\Program Files\android-sdk-windows\platform-tools or that relative to where you install it.

In order to Odin the phone you MUST be in Download Mode. Turn the phone off the press the 1 key while pressing the Power key.
Appreciate the replies everyone. I did have the phone in download mode when trying to Odin but it failed to show the COM message indicating its been recognized. Download & CWM work & boot up, but the computers don't recognize the device and every driver I've tried installing has had no effect.

If no com on the screen your drivers not installed correctly, try unplugging and plugin the cable back in. Try different pc with WinXP if u can cuz Win7 is a real pain unless u doing the drivers right after windows installation. Hope this helps.

The same thing happens with my Epic and new roms...
To solve it, I pull the battery, replace the battery and boot with the Samsung "three finger salute"...
Just hold power+camera+volume down and it will boot direct to recovery. Just reboot from recovery and it should work OK.
I just purchased this phone (i9100) last night after a long travel to track it down. today I simply wanted to update the firmware on it and I was using Odin3 v1.85 to do it but It failed and stayed like that for an hr with the phone in the download mode. I finally disconnected the phone and started it back up and it said " firmware upgrade encountered" with the phone on icon on the left a yellow triangles in the middle and a computer on the right side. Almost looks as though the symbols and words are cutting off the screen.
I can boot into the Download mode but the computer does not recognize the phone anymore nor does Odin or Kies. So I cant even attempt to re-flash the damn thing... I'm so upset right now and feel like taking a hammer to this damn phone...
Any help would be greatly appreciated. I've don't everything when it comes to drivers uninstalling Kies, using other computers without Kies installed, different ports and cables. I've done it all as far as i can see.... also I cant return the damn thing as i didn't buy it from a store. so im **** out of luck if i cant get this working.... PLS HELP!
Are you sure you are downloading the right version of the drivers? I ask because it sounds like you bought the international galaxy s II and not the Epic 4G Touch but you asking the question in the E4GT forums.
The phone is Sprint branded and so is the box.

Okay, so for future reference... you have the D710, NOT the i9100. (The i9100 is the international SGS2, different enough from the Epic Touch that you can't flash i9100 firmware.)
That said, if you can get into download mode then all is not lost!!
Restart your computer. Also, when you use odin, be sure to go into your Windows task manager and close any Kies tasks/processes that may be running in background. You only need Kies for the drivers it provided when you installed it onto your pc.
Suggest you put your phone into download mode, and follow the instructions in the 1st post in this thread:
http://forum.xda-developers.com/showthread.php?t=1282420
I tried the instructions in the link. however, the problem seems to that the phone is not being detected by the computer or the drivers dont seem to be working. I tried this on my other computer and while the phone is in download mode it is still not being detected by the computer or odin.... what can be causing this as before the firmware update that failed it was being detected perfectly fine.
I pretty much have the exact same problem as posted here.

Sorry to be the bearer of bad news, but I was never able to get any computer to recognize the phone in that state. I was able to take it to the Sprint store and they ended up giving me a new one for a small service charge. Since you didn't get it at a store I would contact Samsung and give them the story that cooza suggests in the thread you linked. Good luck and post back if you ever get it working, I am still curious as to what was wrong.
The only thing that might be hampering your effort is Kies might be still active. I overlooked this instruction (as was mentioned in a previous post). Before starting Odin or connecting your phone go into Windows task manager (ctrl/alt/del) and click on processes. Scroll down and you'll probably see a Kies process running. End that process, then try it again.
.....
Sorry but Kies has been completely uninstalled from this computer and the other computer.
are you plugging the phone before or after entering download mode?
I did both before and after to see if that would make a difference, but no go.

Guys, I tried Ubuntu but with no luck. The computer simply will not detect the phone. At this point I believe only Samsung can fix or replace this. I will contact them tomorrow and see. Maybe they will do it for free or maybe they will charge a small fee (small I hope if any) but thank you all for the help.
EDIT: Sorry, this post wen't to completely wrong place. Hope some mod can move this to right section.
I know. There's number of similar threats. I have read them all. Or at least feels like it.
I managed to soft brick my sgs2. I was playing with this new lol boot (dual boot app) from market. I think I pushed something wrong in this app. After that my intention was to make a CWM backup before I start to play seriously with lol boot. At the second I pressed backup from the menu, my phone shut down. Now I'm in a sitsuation whre I can't enter recovery mode. There's just this Samsung Galaxy logo. At the time I had CheckRom v4 installed.
My intention was to flash stock rom via odin. I can enter to download mode just fine BUT odin or kies isn't able to connect to phone. Kies is recognizing the usb connection, but fails to connect it properly. Here's a list what I've tried so far:
- Restart PC (100x)
- Restart Odin (101x)
- Restart Kies
- Reinstall USB Drivers (with Kies and without)
- Trying different computer which has never seen Kies or any Samsung USB drivers
- Reinstalling Windows (W7 x64)
- 3 different USB cables (2 stock Samsung)
- Different USB ports
- Also Nexus S USB drivers as mentioned on another thead in XDA
- Starting odin after USB connection, and before
- Googling with any keywords I have come up
Is there anything else I can do for now?
you mean when you try to connect to odin there is no yellow square ?
maybe try to remove battery for + 90 sec and try to enter in odin ?
ps in this situation you must forget kies since its barely work when everything is fine with the phone ...
Thanks for your reply. Odin doesn't 'do' anything when i connect my device. I'm using version 4.43. When I connect s2, windows install two drivers, Samsung Mobile USB CDC Composite Device and Samsung Mobile USB Modem. I also tried taking battery off. Actually the battery wasn't attached for 6 hours, still no success.
I didn't see this in your list, but have you tried entering download mode and connecting?

Guys. I think there is some Android God that came to help me. After ~36 hours of googling, crying and throwing the phone to the wall, I've managed to solve my problem! As I was googling cheap shotgun for me, I had a vision. Why not, let's try older odin. The solution was v1.83. And right when I plugged in my phone with this odin, it got recognized! At the same second! Nuff said, I'm satisfied. And do you know what is the best part? I flashed with original stock rom and every app, every launcher and so on was STILL WORKING and running!
Thanks to everyone. I'll be more careful next time!
EDIT: How the heck the custom binary counter went to zero? I was thinking its only possible with usb jig?
not older odin! but the one u need for sgs2 (and 1) only use odin 3 v. 1.83 or v. 1.3.
The one you said IS NOT FOR YOUR PHONE. Sorry I missed that text.
So if I understood you correctly, u are saying that I flashed my phone with wrong version of odin (1.83) ? Sorry, I'cant understand english too good, so can you say your point more literally and s_l_o_w_l_y? Thanks
I only use odin3 v1.3 or odin 3 v.1.83.
As far as I know, you cannot use anything else, since it is not made for your device!
I might be wrong, if so, somebody correct me.

So if you're correct on this, the reason why I couldn't get my phone recognized was the wrong version of odin?

gratz!
to reset your binary, there is only one way to do it. u are right, usb jig.
however, beware, i read somewhere saying that GB ver 2.3.4 onward has a new version of bootloader which prevent usb jig from resetting the counter, which mean samsung is trying to lock the bootloader now. however, flashing the old bootloader still helps (claim by others).
Hello! I'm having some trouble rooting my device. I have rooted my previous device (i9100) before so I'm not a complete noob about this and I followed the instructions EXACTLY.
What's happening is whenever I hit start on Odin to root my phone it comes up with an error "No PIT partition found". The phone is working perfectly well normal but it just seems to get stuck here no matter what I do. I've searched all over the internet and I cannot seem to find a solution to this. I've tried enable/disable debugging and allow unknown sources downloads. I've plugged into different USB's, heck even different computers and installed Kies on(Phone gets recognised by Kies so that's confirmation that I have drivers). I've also set up Odin first then plug my device whilst it's in recover/download (the home/power/volume down one) and vice versa. Nothing...All I keep getting is that error.
I have no clue what's going on but I have contacted Samsung support. The problem is, is that I bought this device off eBay and the seller said it was an unwanted upgrade. So it was still new and when I checked it was. It's also a real Note 2 (Checked it all). I'm not sure if I can still get warranty so I would love it if anyone here could help me with this!
These were errors coming up using Odin version 1.85. However, I have tried everything with Odin 3.
With the newer version I just get " Get PIT for mapping.."
and it stays there and eventually says Failed.
I am running windows vista on this computer and I tested it also on an older xp computer to which I had no success.

Ive uninstalled kies so it shouldnt be the thing interrupting and have kept drivers because I can still use phone as storage and it recognises it. I am in odin download mode because it says cutom firmware no etcetc. Its all right and ive double checked it. It just doesnt seem tp work :/
I asked the person I bought it off and they said it came factory unlocked and came with his EE contract but it was unwanted upgrade so he sold it. If that information helps
Guys, sorted it out. I tried flashing it through odin on my windows 8 laptop. I think the note 2 will only flash with either windows8 or only on USB2.0 sockets. All computers I have tested and failed on were USB1.0! So happy!
I was running CM10 but I got a message whenever I got into the Camera App that said "Unfortunately, Gallery has stopped working", after a research in here I found that I wouldn't get that msg again if I installed this "gapps-jb-picasa-20121011-signed" thing.
I did, but when I got into my Camera App, I didn't have the other options like "Image Effects" and all that stuff.
So, what I did was to Restore my phone from my BackUp folder that I've created before installing CM10, but for my surprise I got a msg saying "VolumeError" or something like that and other things that I can't really remember... and as a good Mexican that I am, I ignored it and hit the Reboot System Now..
What happened next almost made me cry...
I was expecting to get in my stock rom without any problems and yadda yadda but... OH SURPRISE!
I got stuck on the boot screen, where it says "Samsung" and the website of it and I didn't freak out... I waited like 5-6 mins and took the battery out. When I turned again, I tried to get in Recovery Mode but the screen just kept turning off and on and saying the exact same thing, the "Samsung" logo and it's website.
I hope you can help me and please answer me. I don't know if I'm 1000000% screwed but I will only wait for the worst. Sorry for my bad english and don't hate me for being mexican
I don't know if I can get into my phone from my PC but whenever I plug my phone in, it just loads it as if it was in Charging Mode

Like @dropple said, it seems you stuck "SAMSUNG" and in this case you can't get into recovery so you can't flash CM10 as of now. Go find some tutorials and Odin back to stock via download mode. Then install CWM recovery if you want and do whatever you like. Should get you outta trouble.

Greetings from México and thanks for all your support.
Here's a weird one for you,
Same thing as OP stated. Device is stuck on logo. Can't get into CWM. Was on People's Rom. Device was lagging really bad. Then the system requested superuser permissions. Yes the system requested. Being as I did not request it, I declined. Shut the device down to see if that would help with the extremely bad lag (i mean BAD lag. Like..........................ok it does something then.......................................................................ok it does something else. 10-20 seconds lag)
Connect device to computer to Odin back to Stock or whatever ROM would have worked, computer recognizes device..... wait for it.......
But in download mode Odin does not see it. Com Port will not illuminate. Tried 3 different cables. Tried 6 different USB ports on computer. Still nothing.
Any ideas, because I'm all out?!?
To the OP:
I would follow the instructions in this video from the part where qbking77 talks about putting the phone in download mode, as you presumably did when you first rooted your phone. Download all the files linked/referenced on the site, especially the Samsung mobile drivers, Odinv3 1.87, CWMRecovery, and the deOxed versions of the stock ROM. In sum:
1) get into recovery mode by holding onto the volume down, camera buttons, and then without letting either of those go, press and hold the power button.
if you get into recovery mode, skip to step 4
2) while your phone is completely off, hold onto the "1" button on the slide out keyboard first, then without letting the 1 button go, press and hold the power button until you're in download mode.
3) flash the version of Clockworkmod
4) once in recovery mode, wipe your phone, clear the cache, and dalvik cache, and then flash the deOxed version of the stock ROM

Do you have the mobile drivers installed on the computer you're trying to connect your phone to?
Yes. The drivers have been installed previously. The computer will see the device as "Samsung SPH-D700 Card USB Device". But Odin3 1.85 will not see it.
EDIT: When I put device into download mode and connect to computer, the computer only sees it as "Gadget Serial".

Greetings from Mexico!
I'm using the same version of Odin I used to root the device. Would a different version really help and if so, what version to use?
I actually have a different version of Odin I used for another device and tried that one as well, with no luck.
EDIT: I have now downloaded and tried 4 different Odin programs with no avail. Again, that makes 6 Odin programs, 6 different USB ports, 3 different cables with the same exact results. The computer recognizes device but Odin will not.

Had a simular issue when I had two odins on the same computer, for a lark and as I had nothing better to do, tried installing drivers and one version of odin to a vertual machine running vista and checked to see if my computer's vertual machine would reconize and it did, I took it as a sine that at one point I had done something to my computer's main os sometime between rooting my epic 4g and frying it (recovering from a backup from a different parition layout I think, bad times with bootloops and seeing way to much of the samsung logo.) So as I'm not brave enough to run odin on vm I instead removed all of odin from my main os and all of the samsung drivers, then reinstalled rebooted and repluged my epic in, got reconition and reflashed with plesure.
The other issue might be that your computer is reconizing the device and try/failing/hanging and not allowing odin in. Had an issue when my computer was failing to pop up a 'what do I do with this' window and hanging round in the system. A reboot with the internet unpluged strangely solved that for some reason, might be the reboot might be the combo, but I find better connection reconition with my computer when I've fewer things connected.
Don't mind the spelling to much I clean up with my other device.

Phone does not boot past the "Samsung - www.samsung.com" logo. Plus, as with all of my devices, USB debugging is always checked.
Thanks for the suggestion though. Always helps to double check things.
I believe I am going to take it to Sprint tomorrow.
If I can't get into it, they should not be able to get into to it either. If they can't get into it, HELLO WARRANTY....

I know I've been in your boot problem situation and recovered, it just took persistence and eyenumbing amounts of reading.
Note On the multiple Odin, USB, and driver installation: if you've access to another computer it could be worth wile to run once though on a previously virgin computer, meaning your phone and computers' USB's have never touched. Just do the installation, rebooting, and plugging in exasperatingly meticulous order.

Yep tried the "virgin computer" computer as well. The computer sees the device but Odin does not. Com light will not illuminate.
Sounds grim.
So to rap up all the cables, plugs, computer, and software with odin is out of the debug process.
So I did some digging into the past and if your computer is reconizing and odin is not then ADB (android debug bridge) and the sdk are the other option

The other thing that may work is ejecting the sd card and battery before doing anything. Though its likely something you've already tried.
