Hello @Ben@Network,

Thank you for reaching out to the community, You can download the v19.0 GA from the following links:
> https://www.sophos.com/en-us/support/downloads/firewall-installers
> https://download.sophos.com/firmware/HW/index.html

And then re-image the appliance: https://support.sophos.com/support/s/article/KB-000036812?language=en_US

Then you can download firmware latest firmware 19.0.1  MR-1 from Sophos Licensing Portal: https://docs.sophos.com/nsg/sophos-firewall/18.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/BackupAndFirmware/Firmware/FirmwareDownloadFirmware/index.html

Between after the firmware upgrade did your appliance went into the failsafe mode ? If that is the case then you may check the reason by following the article below:

Hello Vivek,

Thanks for the answer. Since the firewall is not directly in my access, I did not want to install a new image on the firewall. With the version 19.0.0 the firewall runs without problems. However, now when I click on "Boot Firmware Image" on the 19.0.1 in WebAdmin, the firewall boots again with the broken configuration. I am now looking for a way to upload the 19.0.1 version again and have a 2nd attempt to boot a working 19.0.1.

Is there a way that the firewall automatically reboots after a certain time and boots with the previous firmware version, unless the automatic reboot is cancelled by the administrator?

Hey Ben@Network ,

SFOS provides you to slots of the firmware, where in you can switch between the two slots anytime without loosing the configurations. 
So, before moving to the SFOS v19.01 MR-1 if you have the backup of v19.0.0 GA that is excellent. 

And now that the configurations are broken on v19.01 MR-1 then that backup file will be handy. You can load the previous firmware using *SFLOADER: https://docs.sophos.com/nsg/sophos-firewall/19.0/Help/en-us/webhelp/onlinehelp/AdministratorHelp/BackupAndFirmware/Firmware/FirmwareLoadFirmwareSFLoader/index.html

Once you are able to start the v19.0.0 GA without appliance being broke or into the fail-safe mode then you may restore the backup with the file you saved. 

*WARNING: The option to load firmware using SFLoader isn't available for XGS devices. To update corrupt firmware for XGS devices, see Reimage Sophos Firewall. OR the link shared previously !! 

If I understood your answer correctly, the only way to boot a running19.0.1 on the firewalls is to install a new image, update to 19.0.1 and import the 19.0.0 configuration backup? There is no more "remote" friendly way?

Nope if it is broken or in a fail-safe mode then there is no other remote friendly way of restoring it !!
You should take a look into the suggestion given by LuCar Toni. Ben@Network
