I try this code on my board but it still stops at the STATE 0 level and doesn't continue even after a few hours.

Hello,

Can you add a binary file that could be easily flashed ?

I am new to Virtual Studio COde, though my board is located at COM7 but the VS Code tries to flash it at COM14 and I did not find where to change that.
So I went in src folder and opened the ino file in Arduino, installed the SparkFunk ublox library, disabled the version that I don´t need ( 0.7 ) but still I got the following issue:

C:\Users\catal\Downloads\TTGO-T-Beam_GPS-reset-main\TTGO-T-Beam_GPS-reset-main\src\T22-GPS-restoreFactory-v2\T22-GPS-restoreFactory-v2.ino: In function 'void setup()':
T22-GPS-restoreFactory-v2:75:36: error: 'GPS_RX_PIN' was not declared in this scope
SerialGPS.begin(9600, SERIAL_8N1, GPS_RX_PIN, GPS_TX_PIN);
