198 +== 4.6 The old version LA66 is different from the new version LA66. Can OTA_Tool be used for both versions? ==
199 +
200 +
201 +The most obvious hardware difference between LA66 V1 and LA66v2 when burning is the presence of a "RESET "button, and the RESET operation is only for LA66 without a boot loader, you can refer to this link to learn how to upgrade LA66 without a boot loader：[[LA66 USB LoRaWAN Adapter User Manual - DRAGINO>>url:https://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LA66%20USB%20LoRaWAN%20Adapter%20User%20Manual/#H1.10.2Updatemethod:A0ForLA66withoutbootloader]]
202 +
203 +In summary, as long as your LA66 has a boot loader, either LA66 V1 or LA66 V2 can use OTA_Tool.
204 +
205 +
206 +== 4.7 Why can't LA66 burn its own working firmware after it is used for OTA upgrade of -LB products? ==
207 +
208 +
209 +We are sorry for the inadequacy of LA66 for OTA updates in the past.
210 +
211 +* In the past, the download address of LA66 OTA DONGLE V1.0 was (% style="color:blue" %)**0x08000000**(%%), and the address of the bootloader that existed by default when the LA66 was shipped was also (% style="color:blue" %)**0x08000000**(%%).
212 +
213 +Therefore, when you burn OTA_Firmwar v1.0 (LA66 OTA DONGLE v1.0) for the LA66 in order to use the LA66‘s ability to perform OTA upgrades for -LB products, the LA66’s bootloader is overridden.
214 +
215 +So if you need to switch back to the LA66's working firmware, you'll need to refer to this [[link>>https://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LA66%20USB%20LoRaWAN%20Adapter%20User%20Manual/#H1.10.2Updatemethod:A0ForLA66withoutbootloader]] for instructions to burn firmware with a bootloader for the LA66.
216 +
217 +[[image:image-20250122113225-5.png||height="336" width="798"]]
218 +
219 +* For the new version of LA66 OTA DONGLE V1.1, we have changed the supported download address to (% style="color:blue" %)**0x0800D000**(%%) the same as other working firmware addresses, so you can simply use OTA_Tool to burn LA66 OTA DONGLE V1.1 and LA66 working firmware for LA66.
