Now I have 1.1.03 but I would like to try the new update 1.1.04. But If I’m not happy and want to go back to 1.1.03 what do I do then?
A friend of me say:
Downgrade is possible using a USB male to male, a windows PC and a little bit of technical know how. I tried going back from 1.1.0.3 to 1.0.28 and it worked but you need Philips to share the firmware image with you
How can i Get a guide for this And the firmaware image for 1.1.0.3?
I was the friend that said that. 
Keep in mind though that doing a downgrade in this way will mean you’ll lose all settings and modifications that you had made earlier and will of course need to reinstall and log back into any apps you installed.
@Philips_Support_P @IvoGrijt please make a topic that has all past and future firmware images necessary for cable restores available in one place. Also does this release do anything to improve focus?
Thanks a lot Philips. I can just leave it on 0.3 for a while and wait to see if anyone has issues before updating. if something doesn’t work I’m sure they will in a software patch. Thanks to all for the information
Auto focus is not working on ver 1.1.05, so I want to downgrade to ver 1.1.04, please inform me how to downgrade ?
Philips support inform me to use procedure INFO: How to do offline software update?.
I try this procedure, but downgrade can not done.
As the result, v1.1.05 to v1.1.05 same.
Please inform me the procedure of downgrade v1.1.05 to v1.1.04 .
Any New Software Update ?
Ivo mentioned the dev team have moved onto new products, he was checking to see if anything was still happening on the PPM.
