96 +
97 +If user doesn't have LA66 USB Adapter, they can still use other Dragino Device to connect to PC for OTA update. Steps:
98 +
99 +* Find the suitable mode which base on LA66 chip ( All LoRaWAN model with LB or LS suffix , such as SN50v3-LB)
100 +* Update the LA66 USB OTA firmware to the device.
101 +* Connect the device to PC via UART interface.
102 +* Make sure power off or update the firmware back to original firmware , because the LA66 USB OTA fimware is not low power consumption firmware. it will consume the battery very fast.

111 +== 4.3 How about if i upgrade a crashed firmware via OTA update? ==
112 +
113 +OTA update is done via Bootloader and only change the firmware partition. So update a crash firmware via OTA update won't destroy bootloader and user can use OTA method to update again. Here are notice:
114 +
115 +1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.
116 +1. OTA update require a reset or reactivate action. If the crash firmware doesn't have them work, user need to manuall push the physic reset button on the PCB or power off/on device.
