Firmware Flashing Verification Checklist

Before sending a BTC solo lottery miner for brand-unrestricted flashing, record the current firmware version, MAC address, pool settings, and hashrate screenshot. After flashing, verify three things before returning the device to normal use: the miner boots without repeated resets, the pool accepts shares, and the dashboard shows stable hashrate for at least one full test window. Not every failure is firmware-related; weak USB power, unstable Wi-Fi, and wrong pool endpoints can look like flashing problems. In 2026, this service page should clearly state supported device types, what data the user should back up, and what Jingle Mining checks after flashing. That turns a promotion into a trustworthy technical support resource.

Please leave your contact information on the Gleam page first.

After May 3, 2025, our customer service staff will contact you one by one via WhatsApp or Telegram in the order of registration.

We will provide you with the software and assistance required for the 250Kh/s Hashrate new firmware upgrade.
