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

if there is cwm for your device then install cwm via mobile uncle tools and reboot into recovery and flash your stock rom

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.

Please someone tell me that my theory is True
