Just to be sure that i understand you correct. i dont have option in settings to boot in stock recovery ( only have Reset all setings). So i use Mobileuncle Tools app from store There is option "Into Recovery Mode" (reboot into recovery mode) Shoud i use that optrion ??
PS: Can i use Rom Manager or Root Browser to do that?
Many Thanks

Yes, i try almost every option usb debugging on/off, restart,recovery mode but Nothing help so far.

PS: Strange thing is that, the last days when USB mass storage/usb debuggings was still working: when i connect the USB cable the pop up USB message start to pop up ON/OFF many times without i do anything.May be the USB cable is broken. i think i find what is the Problem, The USB cable its like Iphone 5 pin USB. I just open it and find that one of the four cable was little damaged, the other three are fine .Maybe thats why the Phone charge.Maybe The damaged one is for data.To charge the phone with usb you need only voltage cables right? If data cable is broken( little damaged) you cant get usb data right? Maybe thats why when UMS was still working its just turn on/off many times without any reason and thats why USB debugging Not working too,because of the Data cable in USB. When i get new cable and will post results.:good:
Please someone tell me that my theory is True

And try to disable User Account Control too

yup...definetely worth to try. you may also reconsider to change your cable data since it could be the source of the problem.

yes.. the samsung original cable that is supplied with the phone has problems with me.. i used a BB cable data and it works well.. you might giving it a try..
and make sure that you r using stock rom cause kies wont recognize your device if you r on a custom rom....
Thanks for such a quick response guys.
I wiped cache with ccleaner and did a complete PC scan too. No luck.
I tried other USB ports too. Now im gonna try BB cable, cause I doubt my cable hardware now.
Thanks all.
Solved.

basics:
hold down the notification bar and press " connect to usb"
even without installing the drivers you can still connect to your phone
but i advise you to install them
try READING before POSTING
SolutiON IS herE
try to reset ur sgy and then retry again or if it shows usb connected in notification bar open it and select connect usb storage
hope it works:cyclops::victory:
This has happened to me before.
There must be a problem with the installed drivers.
Uninstall drivers
Uninstall kies
Reboot
Clean pc with any cleaner
Now connect to Internet and then connect your device.
Drivers will be downloaded. Just wait.
Worth a try right

[Q] Nexus 7 (flo) not connecting to PC????

im not sure if ive been looking in the wrong places but i cant find an answer to my problem. so i rooted my nexus 7 about a week ago and installed twrp. everything was working fine until i accidentally pressed wipe data instead of factory reset. i deleted EVERYTHING on my tablet including my operating system, the only thing left was twrp :crying: today my otg usb cable came in and i installed that unofficial cyanogenmod build and now it wont connect to my pc. i have usb debugging on and everything. i go to device manager (on my pc) and it is listed as "Nexus 7" but when i try to install the usb drivers it says that they dont work for it. how can i get the usb drivers to work again?
Note: its not my pc cause my rooted s3 works just fine with my pc.
sorry for being a noob! and thanks for the help!
I actually have the same issue where my Windows won't let me navigate my N7 as a portable device. Tried a whackload of drivers and the like to no avail. To transfer files I just end up using ES Explorer. Funny enough, ADB in recovery works just fine.
If it is the same as PA and PAC, try Settings > Storage > Press Menu > USB > Check MTP

Were you on stock before you wiped? Trying going back to stock and see if you can get MTP working, then start introducing the parts until you figure out what broke.
The USB IDs for the MTP device change more often than you'd expect causing recognition problems.
For example, on stock, with USB debugging enabled, it advertises one USB ID and also sends out a MTP-compatible flag. When USB debugging is disabled, a different USB ID is sent, minus the MTP-compatible flag.
I helped someone on a different ROM force the MTP device drivers to associate, but then the drivers couldn't initialize the device. This might indicate there is a problem on the ROM side.

If your ADB works in recovery then you must have installed some other adb device driver, other than Google's, at some point.

tried as suggested, to insert USB cable as 80-90% but no luck, phone gets detected in MTP mode, but not in odin... tried with 4,5 different cables.. but same result (all samsung provided cables only)..
do i need to do any changes in setting, or any other changes ( i have kept USB debugging on. )
is there any other way to flash to custom rom other than odin..

Are you getting a notification/warning message like USB device not recognized?
Try this too... Go to download mode by pressing the keys... Connect cable to your phone but not to pc. When u press volume up to continue. Insert the cable to usb 2.0 port of your computer.
I mean insert the cable in to PC qt the same time when you press Volume Up key when prompted to continue to download mode.
The above method is just for a try.The problem may be with your phone/drivers. Drivers which are essential to detect usb phone flashing parent. Bt kies is enough.
So may be a problem with your download mode.
