Hi, I just bought a meter a week ago from SparkFun since the specs and three leads (current and voltage at the same time) sounded great. I am using Android 9 on Essential Phone PH-1. I have been able to use the meter for about 10 minutes. Now the Android app is stuck in bootloader mode, always wanting to load 1477971088 even though it has that version! It takes over 300 seconds to load and it doesn’t like it if the phone goes to sleep, so I have to disable that… I restarted the phone but now the app says “invalid firmware” and I am loading 1477971088 yet again. But it still insists invalid firmware. If I “continue without updating” at the meter screen, it can’t measure – always “LOADING”. Now after several attempts the batteries are low. I have only gotten about 5 minutes of use out of this brand new meter. How do I return the meter for bootloader repair?
