Hi all.  
I am accidentally bought Boron LTE(US) during preorder. I am in Russia.  
It does not work with cloud, cellular - thats ok. Thats my fault.

Questions:

- can I use this hardware completely without internet connection? Example: as a gateway to my car thru bt.
- can I use Particle Workbench(VS Code) to flash device and use it as driver for something? Example above. I am tried to flash, but the app seems does not starts.

Some logs.  
Compile:

```auto

```

Flash:

```auto
Mikes-MacBook-Pro:target Air$ particle usb dfu
Done.
Mikes-MacBook-Pro:target Air$ particle flash --usb ble.bin

Flash success!

If you don’t want the cellular part at all, you can do that - although your device cannot be claimed to your account without going online.

You’d just need to use `SYSTEM_MODE(MANUAL)` in all your projects to prevent the system from attempting to connect.  
And as one-time setup you should run this code

```cpp
#include "Particle.h"
#include "dct.h"

SYSTEM_MODE(MANUAL);

void setup() {
    const uint8_t val = 0x01;
    dct_write_app_data(&val, DCT_SETUP_DONE_OFFSET, 1);

    // This is just so you know the operation is complete
    pinMode(D7, OUTPUT);
    digitalWrite(D7, HIGH);
}

```

Thanks for reply.

I am already everywhere using SystemMode Manual.  
But nothing happens and green blinking(accounding [https://docs.particle.io/tutorials/device-os/led/boron/#looking-for-internet](https://docs.particle.io/tutorials/device-os/led/boron/#looking-for-internet))

Can you post the output of `particle serial inspect` (in Listening Mode)?

My concern that the device is in some fault state.  
How to reset to blank/factory state?
