The thing about HCIGAR is tht they didn't calibrate the battery on the mod hence all the weird problems arise since most of the problems had nothing to do with the chip. There's a good guy in Facebook posted a setting to calibrate it in the group DNA200 MODDERS. As soon as the replacement arrive(finger crossed) imma upload the settings into the vt200. Try check it out. Til then i only have to rely on my SVIP200. It's not the best DNA200 mod out there (user adjustable 510 non spring loaded, heavy, mirror finish display makes it hard to see during daylight) but still works like a wonder than vt200. Not to forget longer battery life too.
