147 +
148 +== 4.2 How to recover if upgrade wrong firmware via Dragino Sensor Manager Utility.exe? ==
149 +
150 +The UART upgrade via Dragino Sensor Manager Utility.exe is base on Dragino Bootloader. So if you are able to upgrade some file via this tool. It means the device has bootloder.
151 +
152 +
153 +The upgrade via Dragino Sensor Manager Utility is base on firmware level and won't effect the bootloader. If you upgrade a wrong firmware file, you can try below:
154 +
155 +~1. UART upgrade via Dragino Sensor Manager Utility again to the correct version. The password should use the AT PIN for the wrong firmware.  (This method is not 100% work, depends which wrong firmware you have upgraded)
156 +
157 +2. Use **TremoProgrammer **to update firmware.
158 +
159 +3. Use **[[OTA update>>http://wiki.dragino.com/xwiki/bin/view/Main/Firmware%20OTA%20Update%20for%20Sensors/]]**, this is base on Bootloader so it will work. Make you choose the correct frequency band (base on the firmware version in the sensor or use EU868 which is the default setting.)
160 +
161 +
162 +== 4.3 How to use TremoProgrammer to update firmware if there is bootloader in the device? ==
163 +
164 +Make sure your device already bootloader while use this update. Otherwise device won't be able to boot ( can be solve by upload a bootloader to the device).
165 +
166 +LoRaSTv4 Base hardware support UART update firmware. the UART connection is the same as AT Command connection, with the need for two extra action. See below for the steps:
167 +
168 + **Step1**: Set BOOT Switch to **PROG** mode. PROG mode is for update firmware specially.
169 +
170 + **Step2**: Press **Reset** button, the module will then boot into program mode.
171 +
172 + **Step3**: Use **TremoProgrammer** to update the firmware to LoRaST v4.
173 +
174 + **Step4**: Set BOOT Switch to **FLASH** position. Press Reset button again and module will run the new software.
175 +
176 +Below is the method for how to update via **TremoProgrammer:**
