354
355
356 * For the bootloader V1.4, compared to V1.3, his role is to support OTA configuration for T68DL (D let Gino product model).
357
358 So if your LA66 doesn't need this feature, you can also just follow the below to upgrade the firmware instead of the bootloader:

372 === 1.10.2 Update method: For LA66 without bootloader ===
373
374
375 * Explanation:
376
377 For LA66 without a bootloader, we can only burn a bootloader for it in the following way. Because using OTA_Tool to upgrade the firmware of LA66 this address is (% style="color:blue" %)**0x0800D000**(%%) by default, but our bootloader needs to be burned at address .
378
379 Therefore, you can use this method to download the firmware with the boot loader directly or upgrade your boot loader (address from (% style="color:blue" %)**0x08000000**(%%)).

390 The LA66 USB LoRaWAN Adapter is the same as the LA66 LoRaWAN Shield update method.
391
392 Just use the yellow jumper cap to short the BOOT corner and the RX corner, and then press the RESET button (without the jumper cap, you can directly short the BOOT corner and the RX corner with a wire to achieve the same effect).

Mengting Qiu 177.1 399 (% style="color:blue" %)**For the LA66 USB LoRaWAN Adapter v1.2, the hardware design has eliminated the reset button, so the first step we need to use the DuPont wire to connect the BOOT pin to the RX pin. Second, connect the LA66 USB LoRaWAN Adapter v1.2 to a USB hub or computer USB port so that it will enter burn mode. Then follow the steps below to burn the firmware.**
