 ### Cannot enter flash mode
-If your on device button doesn't allow you to enter flash mode or there is none, you can always connect GPIO0 and GND pins directly on the chip. Search on the internet for your chip pinouts and use [the tutorial](https://github.com/arendst/Sonoff-Tasmota/wiki/Hardware-Preparation#bringing-the-module-in-flash-mode).
+If your on device button doesn't allow you to enter flash mode or there is no GPIO0 broken out to the PCB, you can always connect GND to the GPIO0 pin directly on the chip. Search on the internet for your chip pinouts and use [the tutorial](https://github.com/arendst/Sonoff-Tasmota/wiki/Hardware-Preparation#bringing-the-module-in-flash-mode). Be sure to keep GPIO0 grounded long enough (3-5 seconds) before disconnecting to ensure the chip has booted completely into programming mode.
