I`m felling happy to let you know that I`ve managed to make a vkp patch to change the boring signal and battery icons (and a little bit of other stuff like KEYPAD LOCKED IMAGE as well) in w610i R6BC002. All you need is to apply this vkp patch.
USE AT YOUR OWN RISK (I`ve tested this patch and it`s working fine for me, without any problem)
