Hi! I don't know if this is the best place to post this, so feel free to move it. My Eleaf Pico 2 started to have an issue, the minus button was pressing itself every now and then so my watts turned down to 1. Sometimes it'd just stop and I could just turn it up again and vape normally, but others it would just stuck like that for hours, so if I try to turn it up I just get the keylock (from pressing + and - at the same time...). So, I thought about getting a custom firmware to disable the "-" button and get rid of the problem, because now it is definitely stuck. The button itself doesnt seem like it, I mean I can still press it and it "clicks", but still seems like it is pressing itself forever. My problem is that when I try to install the firmware I get an error on "Waiting for the device to restart", so the firmware doesnt really get installed. In the official firmware app i get a device status error, so I cant upgrade from there. Maybe the "-" button being hold is affecting the upgrade? Is there something I can do about it?
