'''Fastboot''' is a powerful protocol that allows for low-level management and modification of a router’s firmware and critical partitions. Fastboot mode provides direct access to the router’s storage, enabling advanced tasks such as flashing firmware, replacing the bootloader, and performing other critical updates. This article provides a guide on how to use Fastboot, specifically designed for the TRB1XX series.

Firmware upgrade process via Fastboot requires only a few simple steps:

#<li>Download the necessary files for TRB1_R_00.07.05.3: kernel.img and rootfs.ubi. These files need to be extracted according to the '''device's product code'''. You can download them from the following link: [https://kaunas.teltonika.lt:444/d/376f07e6f2b5495ebc4b/ kernel and rootfs].</li>

#<li>Open '''CMD''' with admin rights. Use the '''cd''' command to navigate to the directory where you saved the ''kernel.img'' and ''rootfs.ubi'' files (Example: '''cd C:\Test''').</li>

#<li>Open '''CMD''' with admin rights. Use the '''cd''' command to navigate to the directory where you saved the ''kernel.img'' and ''rootfs.ubi'' files (Example: '''cd C:\Test''').</li>

 

#<li>Then use this command: '''fastboot devices''' [[File:4444.png|border|class=tlt-border]].</li>

 

#*<li>If the device isn't listed, please use the [https://kaunas.teltonika.lt:444/d/40841368fece4a64a13e '''troubleshooting guide'''].</li>

#<li>Flash the rootfs and kernel images by executing the following commands:</li>

#Then use this command: '''fastboot devices'''.

fastboot erase boot_a && fastboot erase boot_b && fastboot erase rootfs_a && fastboot erase rootfs_b && fastboot flash boot_a kernel.img && fastboot flash boot_b kernel.img && fastboot flash rootfs_a rootfs.ubi && fastboot flash rootfs_b rootfs.ubi

if a device is not listed, use the following guide for troubleshooting: https://kaunas.teltonika.lt:444/d/40841368fece4a64a13e

<li>After executing both commands, disconnect and reconnect the power to the TRB. The device should boot up normally, running firmware version TRB1_R_00.07.05.3.</li>

 

<li>You can install the latest firmware version on the TRB through the WebUI. The latest firmware can be downloaded from [https://wiki.teltonika-networks.com/view/FW_%26_SDK_Downloads. '''here'''].</li>

#When it completes, use this command: fastboot flash rootfs_b build rootfs.ubi.

#When both commands are executed and finished running, unplug power from TRB and plug it again. It should boot up as normal.

#Install intermediate firmware version, which can be downloaded from here: https://wiki.teltonika-networks.com/view/TRB140_Legacy_FW_Upgrade_Instructions.

#Install desired firmware version to TRB through WebUI. Latest firmware can be downloaded from here: https://wiki.teltonika-networks.com/view/FW_%26_SDK_Downloads.
