A GX6605S board stuck looping in recovery mode looks alarming, but it’s usually recoverable. Here’s the process that worked across multiple bricked test units.
The cause is almost always an interrupted or mismatched flash attempt, leaving the board unable to find valid main firmware and falling back to its recovery loader on every boot. The fix is straightforward in concept: load a correct, verified dump file via USB while in recovery mode and let the board flash it fresh.
The detail that trips people up is file matching — recovery mode will often accept and flash a dump that isn’t quite right for the board, leading to another failed boot and another recovery loop. Double-checking the exact board model and flash chip size before flashing saved a lot of repeated attempts in testing.
On a couple of stubborn units, formatting the USB drive fresh (rather than reusing one that had been used for other flashes) resolved a recovery loop that a correct dump file alone hadn’t fixed, suggesting leftover file system quirks confusing the loader.
Verdict: Recovery mode loops are almost always fixable with a correctly matched dump and a freshly formatted USB drive — don’t assume the board is dead.
