Buonasera a tutti. Pure io ho un AGVTF con firmware 5.3.1 che non vuole più sapere di prendere l'IP Pubblico ( no led Internet per intenderci)
Ho fatto la procedura descritta nel primo post caricando con l'utility il 5.2.1 ma una volta ricollegato alla linea telefonica, si è acceso il led del Service
e dopo una decina di minuti avevo di nuovo il 5.3.1

Avete qualche suggerimento per riportarlo in vita ?
Ho lo stesso problema, con la differenza che la mia versione è AGVTF_5.2.1 ("cerottone") e non si aggiorna collegandolo alla linea ADSL di TIM.
Una volta collegato alla linea telefonica, trova la portante e si accende stabilmente il led ADSL/FIBRA, dopo poco comincia a lampeggiare il led Service (e va
avanti per parecchi minuti!) poi si spegne e il router resta nello stato di "Connessione a Internet: NON DISPONIBILE".
Ho tentato, inutilmente, di fare il downgrade tramite l'utility Thomson con la versione 4.0.8, 4.0.6 e 1.0.0 ma, nonostante sembri prendere correttamente il
firmware, riparte sempre con questo 5.2.1.
devi flashare 2 volte perché il router avvia sempre la partizione con l'ultima revisione del firmware.
non ho capito esattamente come: basta installarlo una prima volta, riavviare il router, spegnere e reinstallare una seconda volta?
Ho provato a collegare la seriale e sembra installi correttamente il firmware.
