Recently, three of my G1 mini units have stopped hashing and I am a little lost as far as determining root cause of the issue. Some information below:
All units were operational and worked fine ranging from 8 months to 18 months.
All G1 mini’s show on local network, show no LED issues (green light on miners), and no power supply issues.
No fan-related issues, they all seem to be working normally.
When the minis are initially turned on, the dashboard indicates a generic “connection refused” error. However, when the minis are reset manually, they show that they are getting work but not accepting any work with a Gps of 0.00 regardless of how long they are plugged in and running.
What I have tried so far that have not resolved the hashing issues:
Connecting G1 mini’s directly to router to see if it’s networking related
Trying different power supplies
Downloading firmware archive from a working G1 mini and overwriting them to the non-working G1 minis.
Yes to confirm, they are all running firmware 2.54. My next plan is to flash them again via microSD card to see if that does anything. First, I’ll try downgrading to a different firmware, then back to 2.54.
Do we need some special device to flash G1 mini with microSD? The slot for putting it in on the unit is much bigger than the SD card itself. Are there any instructions for doing this? I’ve never had to do this before.
Angle the microSD downward when inserting it, I’ve missed a few times and had to remove the case to retrieve it. And any microSD should work, I use 4GB swissbit units but they’re overkill.
With G1-mini off/unpowered, insert microSD card w/ G2.54, unplug Ethernet cable, power on. Green LED will be solid, when it starts flashing some minutes later you can power off, remove microSD card, reconnect Ethernet cable, power on, then reconfigure in web control panel.
Oh okay. So no formatting of SD card needed? Just add the firmware in same format it is downloaded to SD card, then follow @Neo-Geo’s comment to update it.
You need to use a program to image the img file to the card like what you’d use when making a bootable usb for a PC. I use Linux so I just use the built in GNOME disk image writer.
Oh okay, so not as straightforward as I believed. Can you please provide me some more details please? What exactly do I need to do with the downloaded firmware?
Hi! Yes, I have tried using different, functional power adapters but that did resolve the issue.
I have read through this thread as well but I am a little confused with the SD formatting/flashing step and need some clarification please. Maybe @transatoshi can add here as well to confirm.
Your steps are all correct. Once you wait the 5 or so minutes the green light on front will be flashing and the red will turn off. That’s your sign to unplug the miner and remove the SD card then it should be all good to go with the default settings when you turn it back on.
feels bad man.
