Question

I have a 2 x TRB140(1) devices, both seem to have failed and produce no USB or Ethernet connection when powered on
Power light is on, all signal strength lights blink together.

I followed the restore procedure here:
https://community.teltonika-networks.com/24536/trb-140-fw-error-after-update?show=32046#a32046

Recovery using UBI files using TRB1401_R_00.01.06
This worked to bring the device to life and I can get into the WebUI now

The problem is updating the firmware from 1.06.1 to the legacy TRB1401_R_00.02.03.2_LEGACY.bin, as described here:
https://wiki.teltonika-networks.com/view/TRB140_Legacy_FW_Upgrade_Instructions

The firmware loads to the device and allows me to click proceed.  The signal leds start flashing in order, one after the other, for a short while and then I hear the noise of the USB disconnecting, presumably the device is rebooting, and then I am back to where I started, no usb or ethernet connection and the signal lights just flash forever.

How do I get the legacy firmware to load so I can update to the latest?

Hello,

If you are using FW version TRB140X_R_00.01.06.1 or older on your TRB140 gateway, you will need to follow these instructions in order to successfully upgrade your device's FW to a later version. Or install the latest software through WebUI during initial recovery process.

If this does not work, you can contact reseller for a product return - RMA.

Best regards.

Thanks for the reply but these are the instruction I already followed that do not work.  I guess my only option is RMA

I don't think we will be purchasing anymore of these devices as they seem unreliable which is something critical for us (remote location installs)

Fredie,

did you see the private message I sent you 4 days ago? If the steps in it did not help restore the router and install the latest version of FW, it remains a RMA.

Hi SarunasKa 

I only saw it yesterday, thank you for the information

I followed your instructions and was able to update with legacy 02.03.2. Success!!
From there I was able to update to the latest firmware 07.01.4. Success!!

Unfortunately the modem does not seem to be responding, I get the following in the log:
gsmd[find_modem_vidpid_by_id():752]: Modem not found...

Any idea if this is fixable?

Are you sure your product code is TRB140 1*****? Did you used the appropriate firmware TRB1401_R_00.02.03.2_LEGACY.bin?

Basically on the restore method I provided, was enough to install TRB1_R_00.07.01.4 right away, you don't need to use legacy FW.

If you are unable to restore the modem, take a screen shot of Status> System page and send it to me via private message. 

I will try to find the right modem firmware version for you, so you could try to update it.
