Bit of a noob question but can I upload acoustics to W880i/ CID53 using SeTool? I dont want to unlock/debrand or anything, I only want to upload new acoustics as I feel it is a bit on the quiet side (for me anyways lol). Ive know how to upload to CID52 and have installed all the drivers and setool rcognises my phone etc, just want to make sure before ploughing ahead with anything. Cheers.
