Philips: TV Firmware Downgrade Anleitung
vor 14 Jahren
Philips Firmware Update
Tachchen,
[bitte den ganzen Blogeintrag erst komplett druchlesen (inkl. der Updates)]
wenn jemand mit der aktuellen Firmware nicht zufrieden ist und wieder eine alte Version installieren will, kann ein Downgrade durchführen. Zu beachten ist:
Philips empfiehlt generell nicht einen Downgrade, deshalb biete Philips auch keine alten Firmwareversionen zum Download an. Lieber auf eine neue Version warten (kommt in regelmäßigen Abständen)
sicher downgraden kann man nur in einem Software-Branch (hier als Beispiel 2010er TV Firmware-Versionen): also von 140.27 zu 140.25 oder 140.23 – NIEMALS von einer 140.xx zu einer 75.xx Version downgraden (dies kann den Fernseher in einen undefinierten Zustand bringen und man muss den Service kommen lassen)
aktuelle Softwareversionen und andere Daten lassen sich im CSM auslesen
Hier die Vorgehensweise (für TVs, die kein Android als Betriebssystem haben):
TV ist ausgeschaltet (hard off – KEIN Standby – also Stecker ziehen)
die Datei “autorun.upg ” des gewünschten Updates in die Wurzel eines USB-Sticks kopieren
die OK-Taste (oder “Pfeil nach unten”-Taste) drücken und gedrückt halten. Dabei den TV einschalten (USB-Stick muss eingesteckt sein)
das Steuerkreuz auf der Rückseite der TVs geht auch
Nun erscheint das Software Update-/Downgrade-Menü
Auswahl der Datei “autorun.upg ”, welche man zuvor auf den USB-Stick kopiert hat

Update 2 (9.6.2011):
To all users,
We as Philips do not support any downgrade of our sets. In some cases a downgrade can have negative effects and will influence the way your TV set will work.
Quelle: Philips Support Forum
Update 3 (21.6.2012):
Noch ein Hinweise, was die Downgrade-Methode noch für Auswirkungen hat:
this command clears all debug dumps from the flash and resets dump count to zero
Quelle: Philips Community Forum
Update 4 (21.12.2014):
Wenn man einen 2012er TV oder neuer mit doppelseitiger Fernbedienung hat, funktioniert die Anleitung nicht, da die Fernbedienung via Funk mit dem TV kommuniziert. Jedoch ist die Funk-Funktion zu dem Zeitpunkt noch nicht geladen. Jedoch haben diese TVs auch einen Infrarot-Empfänger eingebaut. Somit kann man für diese Vorgehensweise eine passenden IR-Fernbedienung nutzen.
Update 5 (21.12.2014): Bei TVs mit Android als Betriebssystem funktioniert diese Anleitung nicht!
Update 6 (20.5.2015): Bei den Androiden sollte der Downgrade doch funktionieren, wenn man anstatt der Tasten auf der Fernbedienung die Tasten auf der TV-Rückseite (Steuerkreuz) nutzt (Pfeil nach unten). Ich habe dies aber noch nicht selbst getestet.
Update 7 (29.7.2015): Philips TV Firmware Archiv
Update 8 (27.4.2016): Downgrade für TVs mit “Android TV” (nicht alle Serien, auch keine 2014er TVs mit Android 4.2.2):
Telnet Server & Network adbd auf dem TV installieren (über den Playstore)adb debug connection USB to network aktivieren
Minimal ADB and Fastboot auf dem PC installieren (PC muss im gleichen Netzwerk wie der TV sein)Minimal ADB and Fastboot auf dem PC starten und folgendes eingeben
adb start-server (Enter drücken)
adb connect „die IP des TV“ (z.B. adb connect 192.168.1.20) (Enter drücken)
adb reboot recovery (Enter drücken)
Der TV sollte jetzt einen reboot machen und im Up-/Downgrade Modus starten

Update 9 (3.10.2017):
