Hi guys,

I have a P4 and a P3 which I use for water changes.

I would like to update the P3 to work with myGHL but each time I have tried to update the firmware (currently v6.23) I get an 88 error which crashes the GHL.

Using the emergency flashing tool I’ve been able to restore the old firmware, but this process can take many hours with the flashing tool as it will ‘time out’ multiple times (literally I spent 3 hours yesterday using the flashing tool) before the old firmware can be recovered.

The newest firmware seems to be embedded within the Control Centre, so I can’t access it directly to use with the flashing tool. Are you able to post a link directly to the latest P3 firmware so I can download the file?

Unless there is a problem that can be fixed with the automatic firmware update, I assume I will need to use the flashing tool for any updates. I am willing to spend the time trying to do this to get the latest firmware if you’re able to share the file please?

I know the P3 is the old model now and has been out of production for several years, so support/updates are limited. However, this is my old P2 which was upgraded to a P3 so I am keen to keep it working to see just how long it will survive for

Thank you
Andy
