Well, KK has a few bugs on this device and I thought about downgrading to JB using LG Flash Tool. At 80% the USB cable just broke and the device just turned off (the battery was at 100%) and I wasn't able to go into Download mode again.
But, when I connect my phone to my pc (through a new USB cable), i can see my phone in Device Manager:
So I suppose the motherboard is not dead.
What can I do to revive it?
Could a JIG or this (I'm asking about this one as I don't have any factory ROM backup, and it will be hard to get one) work?

I am having the problem very similar to this post: http://forum.xda-developers.com/showthread.php?t=1317916&highlight=USB+does+-work
Though the poster has abandoned the question so I thought it wise to repost.
What I have seen:
When Plugging my device into any computer using any USB cable the result is the same.
If on - nothing happens; no notice on the PC and no charge on the phone. I have tried with debugging on/off, I have tried USB Mass storage mode no difference.
If off - It will turn on the phone and then the phone will show charging state though it will lose a charge and the PC will not say a device was plugged in. Also if phone is unplugged after it is on it will continue to say it is charging until a reboot.
If in Recovery Mode - Mounting any form of drive is not seen by the computer.
If in Download Mode - Device will say charging and drivers will attempt to install on the computer and I will see an unaccessible folder in "computer" that says "samsung i-9100"
I have just checked the web for updates and it says none found. To my limited understanding I am using a Stock ROM with an edited Kernel to give me root access.
I performed the update of the Kernel identically on both my and my fathers Identical phones and his has not had any problems. The only difference between the two is He is still on AT&T US; While I have moved to Hungary. But as I said the problem existed before that
If there is ANYTHING I can gather or forgot to submit that may offer some light to my problem please let me know.
Thank-You Very much for reading.

Joshua Puckett
Fixed - I was using the cable that came with my Storm 2 BlackBerry; and tried after that a Cable I had bought at Radio Shack.
Once I tried the original Sammy cable it all worked;
Thanks to those who looked!

After updated to JB 4.1.1 (i9300XXDLH7)

Hi all,
When I was on ICS, my USB connection is okay, after flashed to JB 4.1.1 (i9300XXDLH7) is not recognized anymore. Please refer to the print screen pic. I cannot go back to ICS via Odin.
I've try to another computer but still the same issues. Also, I've try to install Samsung's USB driver here (https://androidfirmwares.net/Tools/Download/9)

If you have Kies uninstall it and re install if you dont have it install it, then plug in your phone and see if the drivers install correctly it worked for me last time I had a problem similar to this
I just install Kies and try as you advised, still not working, here are the exact error here. Any more ideas?
Some suggestions here:
-Try different usb cables and port.
-Turn off your phone and take out battery for a few minutes.
-Hope you have nandroid backup your ICS rom, restore back your backup.
Sent from my GT-I9300 using xda app-developers app
Uninstall the devices manually in device manager, don't forget to tick the "delete the driver ' option, now restart your pc and install the drivers either from online or through kies
《tapatalked from galaxy s3》
Problem solved!
I try few thing here:
1. Uninstall Kies, turn off my laptop
2. Install Kies.
3. Restart my SGS3
4. Use new USB cable (old connection still recognized by HTC sensation)
I'm not sure which one if the right problem but I try the above steps and it's working now.
Thanks for the suggestions and advised.
Cheers,

I just ask, what the fu*k is Your question?
Make a choice, won't Your computer recognize the phone or the phone doesn't recognize the PC.
I think You're asking for the first thing, so on Your place I would check if USB debugging is enabled, if You changed the "Roman".
Also don't forget to check for drivers on Your PC.
And please, explain to me what "Aataraf" is.
Definition in the existing phone
And you do restore factory settings
The phone hanging on the word Sony Ericsson
And tried to install the original Roman road
Flash tool but the computer does not recognize the phone
But lighting is blinking when you press the back button

I tried to re-install the definition but did not work the way
Where the solution
Can you give me your backup in the original rom
is hard do discover what he want to say, but if you cannot connect your phone to PC check if your drivers are installed corretly. Install SE PC Compaion or SEUS. if you want to use flashtool make sure you have ADB Drivers installed ( you should have it in "drivers"folder, and run the setup wizard) and USB Debug is turned on on your phone.
The battery empty, but when connect the phone electricity are not shipping
just connect it and wait few minutes. it should boot up but it will take a while. It is possible that LED indicator is not turned on. just wait cca 30 minutes.

[Q] No Wifi and Service and Windows wont detect

Hello there!
So I sold my S3 Mini and the buyer asked me to fix his phone. The first problem was that it was stuck in a bootloop and the EFS couldnt be mounted. I got that working and it now boots up normally. Now the problem is that I cant connect to my wifi and it says no service on my cellular. It detects my sim because when I booted it up it asked for the sim lock password.
Another problem is that my Windows wont detect the phone. But it's charging normally. It detected my previous S3 Mini before with no problem. I've even flashed CM11 on it then flash the stock firmware without any problems.
To clarify here are my problems :
1. Cant connect to wifi
2. No service
3. Windows wont detect the phone
The main reason I want it to detect to my phone is to use Odin to flash the stock firmware again. I've tried Mobile Odin but it kept saying to download and install the addons when I've already installed them. Mobile Odin v4.2 if you're wondering. I've also installed the drivers for everything and it wont detect. Thanks for your help.
Sounds like efs is corrupt, try another usb lead to connect to pc, shorter is better.

Any way to fix it? I got the wifi to work by flashing the stock firmware with Mobile Odin. My IMEI is also not correct.
Restore your efs backup.

S905XQ Tomate - *HELP* How to put this *thing* into bootloader mode so I can flash it using USB Burnning Tool? [Pics included]

Hello XDA community! I need help putting this Tomate S905XQ box in bootloader mode so I can flash it using USB Burning tool.
I tried everything without luck.
What I have done so far:
Plugged the USB cable in the PC, hold the visible RESET then UPDATE buttons but unfortunelly, no dice. (Do I have to plug the ac adapter)
Also tried holding the "hidden inside" UPDATE button but also without any luck.
I want to flash Aidan's Custom ROM v9 on this box (1GB/8GB).
Any help is really appreciated, including how to backup this firmware because I haven't found any version on internet.

Try shorting it , the pins are on the chip just above where it says 905x , have the box attached via usb and have the usb burn tool open , get somehing like sim tray tool and one by one place it in between the pins untill it shorts it will connect ...you may or may not need power plugged in and make sure you use the otg usb slot..
Good luck
Thank you very much for your reply! I'll try that on the weekend.
as mentioned above shorting the pins AKA Mask ROM Mode will be your awnser, look at this thread, look for same type of chip as you have (M logo) even if chip aint the same number mask rom mode will probobly (but not always) be the same, there are 2 chips similar to yours in the thread, so try with those 2 first
