## Flash

|

>Note: For Flash updates, we currently only support the use of upgdiff- files! If there is no upgdiff- file for your version available, try to use another method.

1. Copy the firmware update file you want to use in your project folder and click `upload to device` in the Pymakr plugin. Make sure the first 5 numbers match the current version of your modem firmware.

1. Copy the firmware update file you want to use in your project folder and click `upload to device` in the Pymakr plugin. Make sure the first 5 numbers match the current version of your modem firmware. Uploading might take a while because of the large filesize.
|
||||
> Note: If the firmware does not sync to your device, open the Pymakr settings → project settings and add `"dup"` to the entry `"sync_file_types"`. This will create a `pymakr.conf` file in your project and allow you to sync `.dup` files to the device using pymakr.
|
||||
2. After uploading the file, you can run the following commands
|
||||
```python
|
||||
import sqnsupgrade
|
||||
sqnsupgrade.run('upgdiff_old-to-new.dup')
|
||||
```
|
||||
```python
|
||||
import sqnsupgrade
|
||||
sqnsupgrade.run('upgdiff_old-to-new.dup')
|
||||
```
|
||||
3. The update takes about 5 minutes. Note that the update may seem to 'stall' around 7-10% and again at 99%. This is completely normal.
|
||||
>Note: **Do not disconnect power to the module during the updating process**
|
||||
4. The updater will show the new `SYSTEM VERSION` when it is done, and return control to REPL.
