Hi Alex – thanks for the really quick response. Have had the day off today so have tried what you suggested but unfortunately after the installation, I managed to do a factory reset (reinstall TV) but when I tried to upgrade via the internet the screens never refreshed, so after getting to the menu to do the upgrade the screen went blank. If I clicked back on the remote it would go back and eventually I would get back to the (glitchy) android home screen. Everything was running very slow and with frequent hangs. Tried a few more times to get the upgrade to work and even though nothing on the screen if I clicked the back button on the remote a “do you want to cancel Y/N” came up so I left it running for ages. When I came back after about an hour it was frozen on the google startup (the 4 circles). Watched it for a while and it would then go back to the Philips logo before then coming to the google logo and ad infinitum. Tried several hard resets which did not really seem to work. I have then tried an older FW (TPM171E_107.1.38.0_upgrade_loader) and this is currently showing the same thing :(
I am trying one last time with the TPM171E_107.1.143.0_upgrade_loader to see if I can get back to some semblance of operation before bed tonight otherwise will leave it off and try again tomorrow evening (working so can’t do it during the day).
Thanks again for the response… will update if anything changes!
