110 +== 4.1 Can i use other devices to connect to PC if i don't have LA66 USB? ==
111 +
112 +
113 +If user doesn't have LA66 USB Adapter, they can still use other Dragino Device to connect to PC for OTA update.
114 +
115 +(% style="color:blue" %)**Steps:**
116 +
117 +* Find the suitable mode which base on LA66 chip ( All LoRaWAN model with LB or LS suffix , such as SN50v3-LB)
118 +
119 +* Update the LA66 USB OTA firmware to the device.
120 +
121 +* Connect the device to PC via UART interface.
122 +
123 +* 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.
124 +
125 +== 4.2 Where to find OTA Password? ==
126 +
127 +
128 +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.

131 +
132 +
133 +== 4.3 How about if i upgrade a crashed firmware via OTA update? ==
134 +
135 +
136 +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.
137 +
138 +(% style="color:red" %)**Here are notice:**
139 +
140 +~1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.
141 +
142 +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.
