Unable to Flash esp32 after Enabling Deep Sleep

[Smooth]

Hi,

I recently bought TTGO T-Beam, which is a loraWAN development board with an esp32 mcu.
I have been using the Arduino ide to program it and has been successful on that part until today. After uploading a sketch that implemented deep sleep I am now unable to upload any further sketches. The board immediately goes into deep sleep after boot and prevents me to connect to it. I can see that windows detect it for a second before it disappears again. How can I prevent the mcu from loading the program so that I can flash it again?

Thanks for all help!

Did you tried with GPIO0 grounded ?
