TCR100 Device Recovery Options
This chapter is an overview on various recovery options for a TCR100 device.
Default login information[edit source]
Using recovery methods resets the device's configuration to its default state. Therefore, you will need to use the default authentication info in order to login to the device. The default login information for TCR100 is provided below:
- Default Address (LAN IP): 192.168.1.1
- Default Username: admin
- Default Password: see password on bottom of the device
Factory reset[edit source]
A factory reset returns the device back to its default factory settings, i.e., it deletes all custom configurations. Below you will find various methods of performing a factory reset on TCR100.
Additional note: SIM PIN on the main SIM card is the only user parameter that is kept after a factory reset.
Reset Button[edit source]
The reset button is located on the front panel of the device:
The reset button has two functions:
- Reboot the device. If the reset button is pressed for up to 4 seconds, the device will reboot. Start of the reboot will be indicated by the flashing of all 5 signal strength LEDs together with the green connection status LED.
- Factory reset. If the reset button is pressed for at least 5 seconds (by default), the device will perform a factory reset and reboot. Signal strength LEDs indicate the elapsed time while holding the reset button. When all 5 LEDs light up, it indicates that 5 seconds have passed and the reset button can be released. Start of the factory reset will be indicated by flashing of all 5 signal strength LEDs 5 together with a red connection status LED.
Additional note: the default button hold time value (5 seconds) can be changed in the router's WebUI, from the System → Administration → General page.
You can also perform a factory reset from the router's WebUI. To do so, login to the router and go to the Backup section found under the System tab (System → Backup → Restore default settings). In the very bottom of the page there's a Restore button that performs a factory reset on click:
Command line[edit source]
You can perform a factory reset via command line by executing the firstboot command. After this you will be asked to confirm the reset. If you're sure, type the letter y and press the "Enter" key. Alternatively, type the letter n if you wish to cancel the reset.
If you agreed to perform a factory reset, next type in reboot and press the "Enter" key. The router will be reset to it's factory settings and rebooted. The entire sequence of events should look like this:
root@Teltonika-TCR100:~# firstboot This will erase all settings and remove any installed packages. Are you sure? [N/y] y /dev/mtdblock5 is mounted as /overlay, only erasing files root@Teltonika-TCR100:~# reboot
The bootloader menu is a special router state used as a recovery tool in case the router becomes inaccessible even after a factory reset. It can be used to upgrade the router's firmware or bootloader version.
Regardless of what the router's IP address was before, the IP address of the router when it's in the bootloader menu state is always 192.168.1.1. So in order to reach the router, you'll have to set up a static IP address that's in the 192.168.1.0/24 network (for instance, 192.168.1.2) on your computer. Instructions are provided in the links below:
In order to place the router in the bootloader menu state, follow these steps:
- Unplug all cables from the router.
- Plug in one Ethernet cable for your computer into any LAN port.
- Press and hold the reset button.
- While holding the reset button, plug the power cable into the router. Continue holding the button for another 6 seconds.
- Release the reset button.
If you followed all the steps correctly, all panel LEDs should light up. This means that the router is in the bootloader menu state. If that is not the case, repeat the steps again.
At this point you should be able to reach the router's HTTP server via this address:
Type it into the URL field of your web browser, upload the FW image file and click 'Update'. Firmware files can be downloaded from here.
If everything went correctly, the update should begin. At this point you can close the browser window. The update will take about 120-180 seconds.
Additional note: don't forget to restore your computer's IP address settings afterwards!
If conventional recovery methods do not help, you may need to send the device to warranty for repair. The warranty process is described here.
