Well, it went pretty fast and easy-peasy this time! :)
He download the Update over Internet and I install it, and at the very end of its installation he just automatically engage to watch my TV on exactly the same TV channel where I left him prior this Update. :)
And now, in this Phillips TV Settings -> Update software -> Current software info, it says that I have installed:
a) Version: TPM191E_R.201.000.248.227
b) Creation date: Tue May 28 10:57:21 CST 2024
In this Phillips TV Android Settings -> Device Preferences -> About, it says also this:
a) Device name: 43PUS8545/12
b) Model: TPM191E
c) Android TV OS version: 11
d) Android TV OS security patch level: 1 April 2024
e) Kernel version: 4.9.285-ab3673, #1 Tue May 28 10:46:32 CST 2024
f) Android TV OS build: RTT2.211108.001 release-keys
For the final touch, I even try just one more time to engage in this Phillips TV Settings –> Update software -> Search for Updates -> Internet (recommended), and it says that there is “No updates” anymore at the present time for me.
So finally, I update everything correctly now, and I have again a fully operable and now even an Up-to-date Philips 43PUS8545/12, 43”, 108cm, TPM20.1E LA chassis, manuf. Nov 2020, LCD TV! :)
