6. Troubleshooting common firmware issues

• Failed upgrade / boot loop:
  • Retry via web UI after power cycle; if still failing, use recovery procedure or contact support.
• Loss of configuration after upgrade:
  • Restore from backup or reconfigure manually; note that some settings are incompatible across major versions.
• Reduced signal or throughput:
  • Revert to previous firmware if possible, or check carrier-specific builds for performance differences.
• Stuck on carrier splash/custom UI:
  • Re-flash official non-branded firmware (may require unlocking bootloader/carrier cooperation).

LTE speeds dropped after update

• Cause: The new firmware reset your band locking or carrier aggregation settings.
• Fix: Re-apply band selection via the hidden engineering menu: http://192.168.8.1/html/index.html#band_selection (Login required).
