Yes, it will if yours is a i9020a or t. BUT you need a VERY steady hand and PROPER soldering equipment.. I had mine in Dev mode but it wasn't flashing anything, so I thought I didn't do something right, took it all back apart, and 20 mins and a popped micro resistor (from too much heat from the soldering wand) later, I had a completely dead phone.. So if you attempt it, be very careful.. If you don't feel comfortable you can do it, I would definitely find someone who can..
