I'll find out tomorrow if mine is good to go now. I'd emailed the seller on Aliexpress, Think Vape and Evolv all at the same time, to see who could help me first. Evolv was first to issue an RMA, so luckily, I got to send it to Ohio rather than back to China. Nick from Evolv said they replaced the chip the same day they got the mod and had it on its way back to me the very next day. I guess they only return ship RMAs via UPS SmartPost, so even though I live just outside of San Antonio, the package has been sitting in San Antonio with UPS since Saturday morning. It's been a little more than a month since I bought the mod, it'll be nice to finally use it. LOL Anxiously awaiting it with tomorrow's mail...
