is often more effective than simply purchasing another cheap replacement.
If your clone has stopped working, don't throw it away just yet. You can often bring it back to life using specialized tools often referred to as "Repair Kits". These are collections of software utilities designed to re-flash the firmware and reset the license.
No more intermittent disconnection when the cable wiggles. This single mod eliminates 50% of daily driver failures.
