Unable to update Firmware after factory reset

mth11,

Welcome to the community! :) 

Kindly try the steps below: 

1. On your PC, download the latest firmware v5.4.2.35 from this link then unzip it.  Save it on your the PC.  

2. Disconnect the GS108Tv2 switch from the existing network.

3. Connect a PC directly to a LAN port (management port) of the GS108Tv2 switch.  Set a static IP address on the PC that is within the same IP range of the IP address set on the GS108Tv2 switch.  

4. Access the web-GUI of the GS108Tv2 switch.  You may use Incognito mode in Chrome. 

5. Go to Maintenance > File Management > Dual Image > Dual Image Status. Check the current-active image. 

Note: If the current-active image is image1 then we need to activate image2 (or vice versa) then reflash the firmware. Let say for example, the current-active image is image1 with firmware v5.4.2.35 and image2 is the next-active which has either an old firmware version or latest version as well.

6. Let's activate image2.  Go to Maintenance > File Management > Dual Image > Dual Image Configuration.  On the image name, select image2 then check the Active Image box and click Apply.  

7. Go to Maintenance > Reset > Device Reboot.  Check the box and click Apply.  Wait until the GS108Tv2 switch reboots.

8. After the GS108Tv2 switch booted up, go to Maintenance > File Management > Dual Image > Dual Image Status. Check the current-active image.  Image2 should be the current-active image. 

From steps 1-5, kindly read pages 7-10 to 7-12 of the GS108Tv2 software administration manual here about Dual Image Configuration and Dual Image Status.  

9. Now that image2 is activated, we will now update the firmware.  Go to Maintenance > Download > HTTP File Download.

10. On the File Type, select Archive.  Then, browse the the latest firmware v5.4.2.35 you have unzip earlier. and click Apply.

Note: After a file transfer is started, wait until the screen refreshes. When the screen refreshes, the Select File option is blanked out. This indicates that the file transfer is done.
