No, what I meant is that you said you originally had chinese software on the device, and you flashed with some other variant, right? Now I am not sure about this but I vaguely remember people are claiming that different variants (especially the chinese) have also slightly different firmware. AFAIK they should all be compatible but some people were claiming that chinese CMD would be better in some cases. Now all this talk of one FW performing better than some other could of course be just placebo effect, but If you only flashed the device main SW without firmware, and if there are some differences, then it could cause something like this, no?
