This has been covered many times over the past few weeks here (days even). There are a set bunch of things you need to try, search for similar threads (try trawling through the last week's worth of posts rather than using search if search doesn't throw up what you need).

Please use the search button
1:install the drivers first..
2:chk the usb*
3:chk the usb port
samsung drivers : http://depositfiles.com/files/42tijy38q

+ try different odin versions
+ use SII usb cable
+ try different usb ports
+ try in another computer, install latest kies and kill all 4 applications with task manager.
And what the hell is "restored my laptop/pc"? Reinstall?

[Q] Yet another Odin connection problem. I'm getting sick of this :(

Hi guyz, i just bought sgs2 yesterday, previously i've been using SGS for the past 8 months
No matter what i do, i can't get Odin to detect my SGS2 in download mode.. !

}
but the weird thing is, it detects the phone if its in 'switch on' mode
These are what i've done:
- installed kies
- installed driver from kies
- factory reset sgs2
Info:
* i even reformat my Windows 7 (i thought it gets conflict with my previous SGS driver) and started everything from fresh but still fail
* Kies detects my phone, i can browse contacts etc. but Odin still fail to detect in download mode
* my phone is a branded O2 Ireland. Sim free
* i've tried on other PC but still fail
Please help me, i lost hope.. i just want to Root my phone
Did you try a different usb cable? And did you close all kies programs?
Alt+Crtl+delete >> Taskmanager >> Processes and terminate everything with kies in the name.
Did you try with usb debugging off and on?

You can try heimdall
Does windows see the phone drives via USB mass storage mode ..If not its your USB drivers and thats what Odin requires .
Tried a different Odin Odin3 v1.3 always worked for me .

EDIT : yes you are i can see the macbook air lable

Nice picture. But waht really I must to do now?
Looks like you need JTAG to fix that. You'll need to take it to a service center.
Why were you using a .PIT file and Repartitioning?

I'll try JTAG tomorrow.
I'll followed this instruction http://www.darkyrom.com/community/index.php?threads/odin-darkyrom-10-2-resurrection-gt-i9000.4272/ . Found this link here.
This is new device for me and while I'm searching before open this topic I'm already fou a lot of mentions to never do it.

You have a JTAG setup? I don't mean a USB Jig. You'll need to take it to a Samsung service center and blag it, maybe tell them KIES froze whilst updating or something.
Nope. I haven't it. SO i'll go to SC
heres a link.Half way down the page is a contact for poland.
http://www.jtagbox.com/riff-jtag-bo...s-unbrick-bricked-phone-riff-box-owners-list/
I used this list to get mine done and it cost 35euros.Each country obviously has a different price though.Good luck.
JTAG bootloader restore not helped.
I feel like a complete loser.
Tomorrow is full diagnostic...
p.s. Could someone say smth about warrantu labels? Where is there situated?
Phone details under the battery .
Warranty details in the box .
You have invalidated your warranty .
Will the service centre notice this /or charge you who knows .
Kies update failed is the best excuse .
jje
All is ok. SC give me a new SG2
Ok, now please be careful if/when flash the device.

'Odin doesn't work the phone/PC don't recognise each other' has been covered here more than a few times over the past week or so. Search for those threads; there are set of troubleshooting steps you need to go through (you've done some of them but not all).
Edit - And please don't double post. Make a thread, wait patiently for help.

Oi ! Stop bumping your thread (Bumping not permitted inside 24 hrs) :-/ I told you how to fix your phone yesterday. As I said to someone else in the same situation an hour or two ago, either keep trying the troubleshooting steps (I'm almost certain you're not doing something really small/obvious as is nearly always the situation with these cases. And to be honest, I wouldn't be surprised if you haven't searched for similar threads as advised), or take it to a service centre.
And I'm not posting to this thread again, so you can forget about the drip feed/20 questions thing.

Is it not recognizing at all, as in your go into your Device Manager and it doesn't change at all when you plug and unplug the device, or does it not load the driver correctly? There's a big difference between the 2 and how to resolve.

Well, there's either another mode for it to be in to let the PC recognize it that you haven't found or it's really in trouble. Unfortunately, I've no idea.

Since you want to keep your data, try to get into download mode and flash a kdz.
If that doesn't work, I'm afraid you are gonna have to do a "hard reset" (factory reset/data wipe).
May you provide me with a good tutorial for doing it?
Here is one: https://forum.xda-developers.com/showthread.php?t=2797190
If it doesn't work, just use Google to find another one.
I will tell you about the hard reset, if you want.
I am problematic - and some alternative because I cannot install stuff on this PC - some portable version of LG drivers? I cannot find

Nope.
Get an admin to install it.
No way around it.
Unless you want to try the hard reset, which doesn't need a PC.
But you will lose all your data.
Sic! But on the downloaded mode, it's writing unrooted user b13>?
Sic! But in downloaded mode there's info that it is unrooted user b13>?

Even better!
That is meant for LG's engineers to see if your phone is rooted when you sent it in for a fix under the warranty.
If it says rooted, they will mark warranty void and won't fix it, unless you pay them.
Anyway, it let's you flash no matter what it says there.
So go ahead and flash the kdz.
Okay, cool for me.
I already started it but
1st I am not sure which version I have, can I check it somewhere
2nd the tool shows that my phone is disconnected

Make sure that the cable is good.
The older it is, the more likely it is to cause issues during data transfers.
My suggestion?
Get a new one.
Or, you could borrow one from a friend, but make sure it works on data transfers, not just charging.
I made 2 kdz flashes but the phone still bricks. Rescue data, but all in all install Lineageos- CM RIP. Thank you!
