* LR5.xx is for CAT-M1
* LR6.xx is for NB-IoT
The firmwares for CAT-M1 and NB-IoT are fundamentally different and cannot be used interchangable. The last 5 numbers define the firmware version. A higher number represents a newer firmware.
> Our newest products ship with firmware version CatM1 47510. There is no major difference between the latest public version 41065 and 47510.
The prefered method for updating the LTE modem is using `upgdiff-` files, as these updates are faster. Check in the zip archive wheter a upgdiff- update for your version is available. When using a `upgdiff-` file, you do not need to use `updater.elf`

There are several different ways to update the firmware of the LTE modem.
1. [Flash](/updatefirmware/ltemodem/#flash) (slow)
2. [SD card](/updatefirmware/ltemodem/#sd-card) (fastest)
3. [USB](/updatefirmware/ltemodem/#usb) (medium)

Our newest products ship with the modem firmware version CAT-M1 5.4.1.0-50523. At the moment it is not possible to update the modem to that version.

## Note on Updating to CAT-M1 5.2-48829
This update has to be done in two steps and is a full upgrade, meaning you can only use the steps for 'SD Card' or 'USB'.
1. update with `CATM1-5.2-48829-1.dup`
For the first update you have to also specify `load_fff=False`. Using the SD cad method, it would be like this:
```
sqnsupgrade.run('/sd/CATM1-5.2-48829-2.dup', load_fff=False)
```
wait until the LTE modem resets and prints out something similar to this:
```
Resetting............
Your modem has been successfully updated.
Here is the current firmware version:
UE5.0.0.0d
LR5.1.1.0-39529
IMEI: xyz
```
2. update with `CATM1-5.2-48829-2.dup`
```
sqnsupgrade.run('/sd/CATM1-5.2-48829-2.dup')
```
At the end reset the board.
## 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. 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.
