My Raymarine C120 Classic was stuck in boot loop

I followed the advice given and tried to update it however it got stuck at 27%

I eventually had to turn it off now it hangs at 0% when trying to update.

Any advice is appreciated

Welcome to the Raymarine Forum Craig,

It is recommended that any chart card be removed from the MFD's memory card reader and that a Factory Reset be performed to restore operation of the C-Series Classic MFD. The most common cause for a MFD to not accept a software update is due to an incompatible CF memory card.
