### Cannot enter 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.

Be sure to press the button correctly, you must "feel" a click.

Be sure to use a **USB Data Cable** and not a cheap loading cable for mobile phones for connecting the serial-to-USB adapter to your computer. If you are unsure, just try another USB cable. Data USB cables are often thicker than the normal loading cables (and more expensive).

Another problem can be the connection of GPIO0 and GND. Be sure to press the Button correctly, you must "feel" a click. If your device does not have a button, find your chip pinout on the internet and short GPIO0 pin to GND with a wire (or anything metal) as described in [Hardware Preparation](Hardware-Preparation#bringing-the-module-in-flash-mode)

Another problem can be the difficulties in getting the ESP chip into [programming mode](#cannot-enter-flash-mode) when it boots.

If the flash still fails or the progress interrupts, it could be that your computer or serial-to-USB adapter doesn't provide enough powerto the device. Try another computer or use an external power supply (3.3V one).

Use the correct serial-to-USB adapter driver. Check the model of your adapter chip and get the correct driver.

Better unpower your device and check if the wiring is correct and the voltage is on your FTDI is set to 3.3V.
|
||||
If you've connected VCC to the wrong pin it might cause your device to overheat and destroy it.
