91 91  
100 +
101 +If user doesn't have LA66 USB Adapter, they can still use other Dragino Device to connect to PC for OTA update.
102 +
103 +(% style="color:blue" %)**Steps:**
104 +
105 +* Find the suitable mode which base on LA66 chip ( All LoRaWAN model with LB or LS suffix , such as SN50v3-LB)
106 +
107 +* Update the LA66 USB OTA firmware to the device.
108 +
109 +* Connect the device to PC via UART interface.
110 +
111 +* 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.
112 +
113 +
114 +
115 +== 4.2 Where to find OTA Password? ==
116 +
117 +
118 +Each device has a shipped label with OTA Password which is 16 chars. like below. If user don't find this, please send us a photo for the device with Dev EUI to [[support@dragino.com>>mailto:support@dragino.com]] . and we will search the password for you.

122 +
123 +== 4.3 How about if i upgrade a crashed firmware via OTA update? ==
124 +
125 +
126 +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.
127 +
128 +(% style="color:red" %)**Here are notice:**
129 +
130 +~1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.
131 +
132 +2. 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.
