7.1	137
14.1	138	== 4.1 Can i use other devices to connect to PC if i don't have LA66 USB? ==
	139
	140
20.2	141	If user doesn't have LA66 USB Adapter, they can still use other Dragino Device to connect to PC for OTA update.
	142
	143	(% style="color:blue" %)Steps:
	144
14.1	145	* Find the suitable mode which base on LA66 chip ( All LoRaWAN model with LB or LS suffix , such as SN50v3-LB)
20.2	146
14.1	147	* Update the LA66 USB OTA firmware to the device.
20.2	148
14.1	149	* Connect the device to PC via UART interface.
20.2	150
14.1	151	* 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.
	152
19.1	153	== 4.2 Where to find OTA Password? ==
	154
20.2	155
19.1	156	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.

20.1	161	== 4.3 How about if i upgrade a crashed firmware via OTA update? ==
19.1	162
20.1	163
20.2	164	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.
20.1	165
20.2	166	(% style="color:red" %)Here are notice:
20.1	167
20.2	168	~1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.
20.1	169
20.2	170	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.
