I seem to have bricked my SG105

Question

Hey everyone, 
 
 So I was gifted an old SG105 that I'm using to learn Sophos and while trying to get the configuration going I attempted to upgrade the appliance to UTM 9.711-5.1 through an .iso from https://www.sophos.com/en-us/support/downloads/utm-downloads . I ripped it to a USB and booted the SG with it, everything with the install was going smoothly until I got an error that it couldn't find install.tar, which seemed odd considering it's definitely in the download package... So I unplugged the USB and rebooted the appliance but now all I'm getting is a blinking cursor. Even if I have that same USB inserted it doesn't do anything except show the cursor. Did I just completely brick the thing? Hopefully not...

Hello FlashErickson , Thank you for reaching out to the community. This happens because during part of the installation process. the USB drive is un-mounted and needs to be mounted again. 
 It also expects to find install.tar at /install/install/install.tar and so we must mount the device to the /install path. 
 You don&rsquo;t need to be a wizard to re-mount the USB stick. It&rsquo;s also not difficult to list all the drives and pick out your USB device address from the list. Keep reading to learn how to fix this easily: 
 Step 1: Reboot the server. 
 You can&rsquo;t get past this error and start over without rebooting. 
 Step 2: Boot from the USB. 
 You&rsquo;ll need to load all the way up to the installer, but don&rsquo;t start the install yet. 
 Step 3: Open the Shell 
 press ALT + F2 before proceeding with anything else. This will open the shell, where we will run our command to re-mount. 
 Step 3: Re-Mount the USB drive. 
 The main command you will be running will be something like this 
 mount /dev/sdb1 /install 
 /dev/sdb1 was the path to my USB stick&rsquo;s boot drive. 
 
 You can find yours by running fdisk -l to list the disks 
 
 If you don&rsquo;t have any other devices attached to your server, it will most likely also be sdb1 for you. You can confirm the mount success by running ls- alF after mounting to get a directory listing, cd over to install dir and check it out. 
 Step 4: Exit the Shell Safely. 
 Press ALT + F1 to quit the shell 
 Step 5: Install. 
 Run the installer and enjoy your new Sophos UTM! 
 Notes: Q uit the shell with ALT + F1 and proceed directly to installation without doing anything in-between. 
 Some helpful commands are: 
 
 cd to change directory 
 ls -alF to view directory contents 
 fdisk -l to view disks attached to the system
