Hi Guys,
I finally able to recover my g1 mini to original firmware.
The reason was from the way I created the bootable microsdcard is not correct. My card was not fully formatted before running that tool.
Basically, after we run win32diskimager, there should be 3 partitions like this in same card
When it’s done, we just insert in tfcard hole then turn on the miner, both led will blink then the miner comes back to original state.
One more thing, every changes in the miner will be only affected after we reboot it.
Have fun.
