Samsung Galaxy S2 in excellent condition throughout -

Samsung Galaxy S2 in excellent condition throughout comes with charger. The phone has a software problem as i tried to upgrade software to Jelly Bean however i put on the wrong ROM and now the phone is slightly funny as the screen only flashes. Computer recognises the phone on Samsung Kies. Anyone good with computers can flash the ROM and put on the right ROM and it will work or 25 to get the ROM upgraded in a phone repair shop. Only selling as i decided to upgrade to Note 2. 130 07852589757
