We are sorry to hear that you are experiencing this issue. Please try the below steps and let me know if this solves your problem.  You will need the following:

 

  1. A USB thumb drive
  2. Download the latest firmware for your codec from here, select your codec model on the page and click the 'green' download button.

 

Steps:

  1. Using an empty USB stick, preform a full format rather than a quick format (either fat or fat 32 format) on the USB stick. Copy the downloaded file onto the root directory of the USB stick.
  2. once the firmware is downloaded rename the file to TLR5200.bin and place this in the root directory of the USB thumb drive. (When you look at the USB structure it should be blank but for one file named "TLR5200.bin")
  3. Make sure the USB stick is unplugged and power down the codec
  4. Power up the codec whilst holding the ‘OK’ and ‘Hangup” buttons together. The PPMs should flash a couple of times. When this happens release the buttons. 
  5. The codec should now enter the "recovery" mode, as indicated by the orange LEDs sweeping left-to-right.
  6. Insert the USB stick into the codec.
  7. When the codec detects the USB stick the orange LEDs will stop their sweep and the green LEDs will start lighting up as the firmware is copied from the USB stick.  This indicates that the firmware upgrade is progress. It should get to at least halfway through the rows and then PPMs should remain blank for about a minute; if it hasn't progressed further within about 3 minutes or it seems to be in a loop of getting 3 or so lines up, followed by a red line and recovery restarting, unplug the USB stick, unplug power and put it back into recovery and repeat this process. 
  8. When recovery has completed, the PPMs will be unlit and you will not see any PPM activity for a minute or two; you may see the front panel LCD flash intermittently. You can then unplug the USB and the codec should automatically reboot or you can power cycle the unit.

 

- Note: if you don't remove the USB stick from the codec then on reboot, the codec will not be able to complete the boot process as it will attempt to run from the USB stick - if this happens simply remove the USB stick and power cycle the codec.
