Windows won't recognize my SGS2

Hi,
I have for two days tried getting my PC to recognize my SGS2. With no luck. I want to ROOT my phone.
I am using Windows 7 64-bit and gingerbread v2.3.5
- USB-debugging is turned OFF.
- I have tried to format the SD-card, even used different SD-cards.
- I have tried using another PC, with no luck.
- Tried diffrent versions of Kies; 1.5, 2.0, and 2.1
- Tried diffrent versions of the Samsung Mobile driver; 1.3 and 1.4.8
- Tried using a different USB-cable (the one I'm using, is original and i can see that my phone is charging.)
- I have formatted the phone several times.
- I have tried typing *#7284# and changes the USB setting from Modem -> PDA
- Windows Drivers are up-to-date.
- I cannot see anything in the Device manager.
What else is there to do? Is something wrong with my phone?
Is there any APK, besides from Gingerbreak, that i can use to root my phone?
Cheers

Could you tried it in another PC with Windows XP?

When you plug it in to the USB port... Does the phone start to charge up?

Sounds like a hardware issue, i too have Windows 7 X64 on my laptop and no such problems.

Give a shot with USB debugging to ON.

I had the same problem.
This may sound stupid, but it does work, try another USB port.
I just plugged my USB cable into either one of the front USB ports on my PC (WinXP) and sometimes the phone connected (Debugging ON: phone was an external hard drive. Debugging OFF: phone connected to KIES) and other times it didn't. I tried toggling the Debugging, switching off and on the phone, changing USB cables, uninstalling KIES and then reinstalling KIES.
I finally noticed that the phone worked fine on the front left USB port and not on the front right. I have the same thing happening on my work's PC (only it was the front right port that worked). The rear USB ports didn't work.
I doubt that it is a problem with the PC operating system (I found out later that someone with a Mac had the same problem). It therefore must be with the phone's software recognising a connection with a computer and only wanting to connect through that initial connection port.

ive noticed this problem too of it only working with certain usb ports and not others on the same pc. Quite annoying when i was trying to use my phone to transfer some files from another computer and the phone wasnt picked up by the computer.
I think it may have something to do with using MTP rather than standard USB mass storage.

Never plug your phone or any other usb powered device into your front USB ports. most of them do not supply full power. As a matter of practice you should always plug your phone into a direct motherboard USB port on the back of your computer.
I had the same problem with my front ports several times on several computers. My first galaxy S1 would not work on my front port either. all problems were solved by plugging into the direct motherboard usb ports.

Why would you turn USB debugging off?

Do you have Administrator rights?

try installing drivers manually on your pc
and then plug the phone ( usb debugging off )

Try 32bit system
Try using a 32bit XP or 7 PC someone I know had the same problem their Win 7 never gave the problem when flashing or connection with their SGS2 for over 6 months. And just the other day they had a problem so they used a XP 32 bit PC connect ok flashed ok once the phone was rebooted they connect to their Win 7 64bit and the PC saw their handset. So what gives

I have plugged in many different phones and other devices that take their power from the Front USB ports on my PC. Power has never been a problem. Recognising a device can sometimes be a problem (but the same problem happens with the rear USB ports).
I regularly charge my SGSII via the Front USB port of my PC (both work and home). Quite a few of my workmates now do the same because a spare microUSB cable is much cheaper than a good mains charger and also they can back up their phone and transfer files as well.

This worked for me
1. Unplug the USB cable
2. On the cell phone, dial the following number: *#7284# Once the last # is hit, the PhoneUtil application is launched. Choose USB -> Modem and then USB -> PDA mode. The good mode should be PDA. Even if the mode is PDA, switch to Modem and then back to PDA.
3. Plug the USB cable.

Sometimes if you're not using the cord that came with the phone it won't recognize the phone
I had the same problem with my phone but I found the cord the phone came with and it solved the problem

Try turning off your antivirus first for drivers to install. Worked for me.

I have just installed SiyahKernel 2.3 and Windows 7 Ultimate 64 bits did not recognize my SGS2.
What I did is turn on and then turn off the "USB debug" option. It was off at the beginning but... I did that just in case and...
That solved my problem.

Similar issue
My phone charges when plugged in but won't mount. It worked fine until about a month ago.

I'd similar problem.
My SGS2 couldn't be connected to PC (Windows 7 Ultimate 64bit) by USB cable, but it could be connected via Wi-Fi. I found out, that my, however original, USB cable was faulty (could only supply a juice from USB port ). When I used my wife's cable (she's got SGS2 too), everything was fine: my phone connected to PC, Kies v.2.1.0.11112_41 checked firmware and wanted to update, but couldn't do it, because battery was almost flat - I'm charging it now.
Will see tomorrow, however I was able to connect SGS2 to PC via USB cable

Still having the recognition problem, however you can get around it a number if ways. Use Kies wifi to get files to your phone. Use mobile Odin to flash.
Highly recommend to pay the $2 for pro version, that way it will stay rooted.

[Q] I cant connect ny hd2 on my computer

Hi im new here
I got my hd2 when it first came out running winmo 6.5 now i just cant connect it to the computer tried more than 1 computer and more than one cable when i connect it only charges i receive nothing on the computer like i used to before i have tried everything in the setting usb to pc still same thing
please help me how can i connect it
and i also tried hard resetting it more than once same thing

under settings tab -----other , there will be a usb to pc button

I bet you have tried all setting changes so since you have done a hard reset and it still doesnt work, it has to be your micro USB cable. I had the exact same problem as yours and i feared that it was the micro USB port that was faulty. But then i tried a different micro USB cable and it works perfectly. Hence, it is likely to be your cable. Im not bad mouthing HTC because of the amazing work they have done, but their accesories seem to be a bit down on quality. My original micro USB cable is now frayed and almost severed, my Touch HD micro USB is also frayed and the original earpiece is now experiencing audio balance issues.

the thing is the cable that comes with the hd2 i lost it but when i was using it i could connect
but now im using nexus one cable and Nokia n900 cable to connect to the computer and it just charges like i said nothing appears

Have you tired different ports in your computer or tried reinstalling the drivers? To do that, uninstall the Activesync or Windows Mobile Device Center in your PC and reinstall it. Then try. If you still cannot connect your HD2 to the PC for USB mode, then im afraid the micro USB port in your HD2 is faulty. Try the above. Meanwhile, use the SD card method for flashing or transfer files using wi-fi or bluetooth.
Good Luck

If your HD2's USB port doesn't work you can connect to ActiveSync via bluetooth. I do that very often for a quick synchronization, and since HD2 has an Activesync profile it's easy to configure...
Anyway, check that "accept USB connections" option is selected in your pc ActiveSync configuration.

Most probably, he's facing the da** usb port breaking issue.

[Q] wireless charging, can you connect to PC also?

so that i can copy over files/use side sync if needs be but also charge the phone properly and not slowly by connecting it to a PC usb port?
can you have the charging pad connected to a plug but also have the phone connected to a PC via USB for this?
i can't enable wifi since i always have my home BB maxed out and always use LTE

No

what happens if it's connected to a PC via USB and mounted and you then place it on a wireless charger?
seems stupid to have this tech, but have to go back to plugging in cables to copy data over. if you do that a lot then wireless charging is pointless no?

Use airdroid, it has a lot of uses.

Fried an otg flash drive that I placed on my charging pad while transferring pics.

problem is, i'd need to use wifi and that's what i'm not going to do. i upload PC backups via LTE and copying files to my phone over wifi would be slower than USB.
guess i'm stuck on cabled charging until everyone else copies what apples bringing out soon.

Any PC recognize my moto G4

Hello, i'm having this problem for a few weeks now... When I connect my Moto G4 to any PC, windows doesn't recognize that a new device have been connected to it, and also in the phone I don't receive the notification to select the option of the USB usage, if it's MTP, PTP, only for charge, etc. Someone can help me with this? I don't know what to do, I already installed the moto drivers, and the adb universal drivers can't detect that my phone is connected via USB so I can't do anything about it as long I concern.
P.D.: My phone charges correctly and the USB cable (the original) is working because I used it with differents phones, and also tried with different ports. (I made a factory reset not too long ago). Thank you .
(I'm sorry for my bad english, is not my mother tongue)

When you charge the phone using the wall charger, does it say Turbopower on the lock screen? If it doesn't, it's possible that your cable is broken or a pin in the charging port on the phone is broken. Try another cable.

Yeah, it says turbo Charger when I connect it to the wall charger.

Did it ever work and just stopped working recently?
Try USB 2.0 ports(the black ones) on your computer instead of USB 3.0(the blue ones).

yes, was working before, that's why i don't know what happened, it stopped working like 3 weeks ago something like that, I already tried connecting the phone in all the usb ports that i have on my laptop and my desktop, i'm using two original usb cables, because my brother also have a moto g4, when he comes back from work i'm gonna try connecting his phone on my computers to see if both recognize his moto, but i think it's a problem of my moto.

Could be a broken pin in the USB port on the phone. Hope it's under warranty.

I ran into this issue recently. I think the answer is that you need to be an administrator level on the computer to see the phone as a drive on your computer.

No. I am facing same problem as the OP. Already an administrator. Tried in different laptops as well.

This was my issue on Windows 10. What version are you on?

Same. Windows 10.
