Hi newbie here, I just got my quansheng uv k6 today and was tinkering with firmwarea and everything just showing up saying "version does not match" Or if it got flashed it's completely unresponsive/nothing showing up on the screen I remember the first firmware was 2.1 but now it only works with 1.2 I tried every stock software I can find 3.0 2.0 even I found 2.1 but still says version doesn't match. Is there anyway I can get back to 2.1?
