With 5.00.04 on an LG 55EC930V I have the same problem with Simplink ( HDMI CEC ) in Holland right after the offical update. After 20-45 minutes Apps keep restarting (especially the "TV app". So when I watch tv an app is restarting and I have no TV picture anymore for a minute. After that the app keeps restarting until I turn off and on the TV. I discovered that when I turn off Simplink or pull out the HDMI cable or I disable HDMI-CEC in the system menu of my Raspberry Pi2 the problem is not present anymore. But that would not be a good option because I use LG's remote to control the Raspberry Pi and Pi2. With the former firmware this problem was not there and I was way more happy then. Overview of the problems with Simplink when a Raspberry Pi is connected via HDMI on the different firmware versions for LG 55EC930V I have used: 04.41.32 : TV is getting slower over time and inoperable after an hour or so. TV is not responding to both remotes anymore at the end until a power off and on of the TV. Turning Simplink Off prevents this from happening, as is disconnecting the HDMI connection with the Pi or turning off HDMI-CEC on the Pi's side. 04.45.04 : Not sure about this version unfortunately. 04.45.25: This firmware works fine with Simplink turned on and a Pi or Pi2 connected and it is the best one in my opinion regarding this problem! One minor issue: The responding speed to commands given via the remote over CEC, before the problems start, is better in version 05.00.04 (the first 20 minutes at least). 05.00.04: Apps on the TV including watching TV itself are restarting because of a memory shortage after 20-45 minutes! After that restarts occur until the TV is unresponsive completely. After a power off and on of the TV it all starts again! Turning Simplink Off prevents this from happening, as is disconnecting the HDMI connection with the Raspberry Pi or Pi2 or turning off HDMI-CEC on the Pi2's side. The same problem possibly occurs on LG 55EC9300 (USA) and 55EC930T (Australia) because they seem to be practically the same TV. Possibly even all other LG televisions with this software version + Simplink turned on while being connected to a Raspberry Pi may have this problem as well. I reported the issue at LG in Holland today and I am awaiting their answer. LG: Please do what is necessary to fix this huge problem for a lot of buyers of LG TVs! - Take Simplink's good code from 04.45.25 and merge it in to 05.00.04 ! - Test it very well! Also with the best selling computer made in the UK: Raspberry Pi + Pi2. And please do not test it for 15 minutes only but check the performance also after an hour and even after 6 hours or so. This problem does not occur on Samsung TV's in combination with a Raspberry Pi's as far as I know. - Release it as soon as possible!

My bad. downgrade complete 60lb7500 Thanks simon!!!!

Thanks Simon for generous help and appreciate your hard work.

Hi Simon, I don't see model LB6300 (US) in this list. will you be kind to add this model as well?

Thank you SIMON, you saved my 49UB850V, i used your tut to downgrade from 5.00.04, and worked like a charme

I also encounter problem with connecting to my 42LB631 after upgrading to Windows 10 from 8.1. I updated all Network, Adaptor display driver to the latest one. When I connect my laptop from Action Center, it announces Connected but the TV screen is black and after few seconds it shows an error message of "MIRRORING ERROR, we can't mirror your device screen connected via Miracast. Check you device" In previous Window 8.1, it worked very well. I'm waiting for a solution maybe from Intel, Microsoft or LG.
