After almost 48 straight exhausting hours helping members of our community in Paraguay as well as users around the world affected by this ColdCard attack I have learned that both MK3 & MK4 (could be others) devices are bricking at high rates due to the below factors:
1. Devices using a 9V battery and connecting using ColdPower via usb cable / if the battery is low the device will brick if it’s not getting enough power, and become unusable - the battery doesn’t have to be dead, just providing less than sufficient power apparently. If using a 9V battery don’t assume it’s got enough juice if it’s old - use a fresh one
2. Devices that are plugged in with the charger connected via an international plug adapter unit are experiencing high levels of bricking due to inconsistent connection provided by the cheap adapter units
3. KNOWN and reported already is that the firmware updates are bricking devices as well
This should be information we get out to as many plebs as possible. Many only have a single device to work with and these issues are making an already stressful situation a lot worse
God bless everyone affected and I hope this information helps somebody to avoid these issues 🙏🏼🫡
