"Error connecting Helium Hotspot Miner with application"

[Kanar Al Sammak]

Hello:
We have two devices (Helium Hotspot Miner), and we have done the following:
1- The SD card that came installed with the device was removed.
2- The firmware was flashed on a new SD card (https://software.pycom.io/downloads/pycom-miner.bin.zip).
3- The new SD card is inserted into the device after the flash.
4- The booting process indicated that the device was functioning correctly (first a solid green color for the state-led, the one above the power led, then blinking, waiting to be paired)
5- The pairing process was retried both with the Apple version of the Pymaker app and the Android version.

The error that we faced:

• On the Apple devices side, The same error appeared when we tried with the original SD that came with the device: “Could not read firmware version.”
• The devices could not even be found on the Android version side.

What are the suggested solutions to solve this problem?
