hey guys , my lavabox dna200 chip seems to be fried, due to that i am not living in the states(living in Taiwan) shipping for RMA could cost me more then just getting a new dna200 board so i am thinking what is the possibility of replacing the board my self? i seen some video on youtube and got a few question to ask(since i am a total noob) 1. what soldering tool and material do i need? 2.i want to add a ground wire for the 510 spring connector to the chip( not the mod it self), is it possible? 3. if i want to upgrade the original Fullmax 3s 10Wh battery dimension ( 19.8x26x70mm) are there any other good recommendation ? Please give me some advice, i hope i am capable of repairing my own mod in the future, as i am very welling to invest in the stablized wood hobo dna200, but i need to be able to repair it my self otherwise warrant will be a big problem
