S21 Miner Users Push for Solutions Amid Firmware Dilemmas | Community Frustrations Mount

A growing group of S21 miner owners is asking for solutions as firmware issues persist. Reports of read/write errors on all chains, along with concerns over the control board's reliability and Bitmain's firmware restrictions, have stirred significant unrest.

Context of the Firmware Struggles

One user recounted the frustrating experience of dealing with a faulty PSU that led to failures since rebooting their S21 miner. After trying various firmware versions and USB drives without success, multiple community members echoed their frustrations.

"Useless POS miner," lamented one user, capturing collective discontent. Another miner, after troubleshooting efforts, confirmed, "I've checked the voltage reg cable, swapped PSUs, but the issue follows; I think it’s definitely the board."

Technical Challenges and Recommendations

The problems seem to revolve around a potential memory issue with the control board, prompting debates on possible solutions. Some have suggested using after-market control boards to sidestep ongoing firmware issues. This sparked varied opinions among seasoned miners and newcomers.

Interestingly, one user questioned, "What does the Micro-USB port actually do?" echoing the curiosity of many struggling to flash firmware. Another highlighted challenges faced with firmware rollback, stating, "Nothing I try works."

"The latest firmware won’t allow you to run without all three chains connected—go Bitmain, great job!" one frustrated miner commented.

Key Themes from the Community

• Alternative Boards Discussed: Users increasingly recommend considering after-market control boards as reliable solutions.
