Not able to connect via Kies

I am not able to connect my Galaxy S2 via Kies.
It always throwing error
"Reconnect the device in Samsung Kies(PC Studio ) mode. Current connection mode not supported by Kies".
Are you guys able to connect?
Am I doing anything wrong?
Also I am not able to find download location for Kies(mini) for MAC. Its mentioned in Samsung website but no download location.

You have to disable the USB Debug option from your phone.
Settings -> Applications -> Development -> Untick the USB debugging option.
Hope it works fine for your.
Note: If you are trying to upgrade your phones firmware i'll definitely go to the Galaxy S II Android Development section and check the [ROM + Guide]Official i9100XWKDD/KE1/KE2 download for Odin Flash and Root Guide POST.

Thanks , able to connect now.

not working for me
Hi I have the same problem. Debugging is off.
I also tried to connect with sd card removed but no luck.
Do you guys have any suggestion?
I read on internet but found no other tropubleshoot.
It seems there is a problem with MTP drivers not being installed.
I rebooted phone, computer.
I use Windows XP.
Any idea?
Thanks in advance!

Try to turn debugging on, and then turn it off. That helped me.

[Q] TF101 doesn't connect with PC through USB

Hi guys,
After upgrading to ICS I've been unable to connect my pad to the PC. This is usually not a problem, but last night I needed adb to re-root it. Nothing worked, nothing connected. Tried installing drivers and the Asus sync, but no luck.
Is this a known problem? Anyone got a solution? I doubt it's the hardware as I connected a few days before upgrading...

Found a solution. Went into Settings->Storage and turned MTP off and back on.

THANK YOU! Everytime I plug in my ET4G to the dock to charge it that stupid MTP crap always comes up. Had no idea I could disable it. Thanks!

yeah, this doesn't always help... I had the same problem when i first got my TF101, and i tried all the tricks, the one mentioned here with mtp, enabling and desabling debug mode, turning off and on with usb plugged in, and some others i can't remember... nothing.
In case anyone else is looking for the answer and the quick tips don't work, what did it for me was installing Android Revolution HD rom. I've read that this problem could also be bootloader related.
Anyways, cheers.

How to connect an ICS device to your computer
Step 1. Connect device to computer via USB
Step 2. Set USB connection as Media Device (MTP) (p.s. if you use a Mac you need to download Android File Transfer)
Step 3. Disable USB debugging if enabled
I hope this helped.

when you need turn off MTP it mean your computer doesn't have driver.
If you need using MTP go to asus page and download driver. it's easy to install driver ^^...
recently I can't understand why same file but the computer at my office can't install that file instead other computers working normal... maybe my work place using old windows version...

Like I wrote earlier - mine was actually in MTP mode, but I had to switch to camera mode and back to MTP for it to start working. Thanks for the replies, though. Hopefully it will help some other people with the same problems

Does your phone boot normally? Can you turn on USB debugging?

yes it boot normally and i can turn USB Debugging and it still doesn't recognize with and without USB debugging mode.

When you select recovery from fastboot, that's when you get the "no command" error?

I do same kind of prob with my PC. The root of problem is mostly the USB cable itself. I've got the stock nXs⁴ cable yet after a year its out I think. When that happens try some many cable.
The prob might even occur due to MTP. If debugging is enable then ADB would recognize nXs⁴ as offline and no Portable media device would be visible in My PC. In that case try restarting PC!

Reformat computer or try different computer

Assuming, you have no problem with your USB port, USB cable, installed latest LG USB Driver 4.0.4, running Windows 7 or 10...
We need more detailed info from your part to tackle this problem. Are you running on stock rom, kitkat or lollipop? Are your rooted and do you have TWRP recovery?
Then, you need to disable "USB debugging" from the "Developer options" menu. Then replug your USB cable and you can now select MTP instead of charging only mode. Good luck.

i have fought the no mtp problem and everytime i lost. if you try new things they just dont work. what has worked was to reformat computer then it will work..

I had the same problem with my G2. Unknown usb device, and the error was: "unable to get device descriptor" or something similar. Tried all software solution without success, so i have started to looking for hardware defect. I've changed the usb module, but no success. So, as a last chance, tried another mainboard. And "tadaaaa"... That was the problem. So, start to look for a working g2 with cracked screen, as i did.

Did you try to just reboot the device while having USB debbuging on? This works fine for me in such cases

Yo Buddy I was using MIUI 8.1.2.0? As far as I can remember I had the same issue I was only able to access MTP only via TWRP, but after I flashed LOS(Now I am using Mokke) I was albe to access MTP normally. So your best bet is to flash another ROM

Just add these 2 lines to your build.prop file and MTP will work again:
persist.service.adb.enable=1
persist.sys.usb.config=mtp,adb
Make sure you have USB Debugging enabled.

Thanks, it's work ...

or use Magisk for rooting, it works for me

Hello everyone,
I know this subject is discussed quite often all over the forum, but there is a small difference between the described cases an mine.
The problem is, my redmi 4 prime won't connect to my pc for mtp. Only charging is available. It doesn't offer me to choose between the other options. So far, so known.
Now comes the big BUT:
My phone isn't rooted. Only the bootloader is unlocked but the problem occurred before the bootloader was unlocked.
Since my phone isn't rooted, the common solutions like changing the superuser app or editing the build.prop file won't work.
I noticed, that my phone connects if I turn it off, plug it in and boot it up. So if the phone is connected while the phone restarts it's working. When disconnected again and reconnect afterwards, still only charging is possible.
If this thread is placed in the wrong forum, I apologize.
I'm thankful about every answer.
Happy new year

Try changing the usb cable or use different usb port of the pc. For me, sometimes mtp doesn't work for a bad usb connection.
