GUIDA per il WIPE CACHE PARTITION
I crediti vanno tutti all'autore del topic su ZenTalk, QUI il link di riferimento

Prima di iniziare la procedura, assicuratevi che il telefono abbia almeno il 50-60% di batteria.


[NOTA] :- I tasti volume sono per selezionare, il tasto power per eseguire l'opzione selezionata.
1. Prima di tutto spegnete il vostro terminale

2. Ora che il telefono è spento, tenete premuti insieme il tasto power e volume + fino a che sentirete vibrare il telefono per due volte. A quel punto rilasciate i tasti simultaneamente.

3. Il terminale si riavvierà mostrandovi per prima il logo ASUS. Dovrete aspettare finchè non apparirà a display la seguente schermata nota come Normal Boot.

Spoiler:

4. Ora dovrete premere i vostri tasti volume finchè la scritta "Normal Boot" cambierà in "Recovery Mode".

5. Ecco come apparirà l'opzione "Recovery"

Spoiler:

6. Dovrete quindi premere il tasto power per selezionare la Recovery Mode.

Il telefono si riavvierà prima mostrandovi il logo ASUS, poi con un errore. Con tanto di logo Android e punto esclamativo.

7. A questo punto dovrete tenere premuti insieme il tasto power e volume +. Poi rilasciare il tasto volume + mentre il tasto power è ancora premuto.

8. Il device entrerà quindi in Recovery. Vi darà alcune opzioni da scegliere; potrete fare ciò usando i tasti volume.

Spoiler:

9. Selezionate l'opzione "Wipe Cache Partition" utilizzando i tasto volume. Una volta selezionata la vedrete colorata di blu.

10. State molto attenti a non selezionare altre opzioni o potrete perdere i vostri dati. Quindi assicuratevi di avere evidenziato in blu l'opzione "Wipe Cache Partition". Ora potete eseguire il wipe premendo il tasto Power.

11. Dovrete essere molto pazienti perchè l'operazione richiede tempo. Fate attenzione a non toccare niente, non riavviate il cellulare perchè potrebbe causare un brick. Una volta finito apparirà il messaggio evidenziato dalla casella verde illustrata qui sotto:

Spoiler:

12. Ora dovrete selezionare la prima opzione (Reboot system now).

13. Enjoy

Qui raccoglieremo tutte le segnalazioni dei vari update per il nostro ZenFone 2.

Ecco cosa sarà ritenuto Off Topic:

1. Telecronache del vostro aggiornamento.
2. Segnalazioni di mancato ricevimento/rilascio dell'update e relative lamentele.
3. Post in cui comunicate che attendete l'update.
4. Post in cui ci informate del fatto che l'aggiornamento è riuscito correttamente (informazione superflua).
5. Segnalazioni di notizie senza un reale fondamento ed un link AFFIDABILE dove poterla riscontrare.
6. Commenti e supposizioni su probabili aggiunte o modifiche ai prossimi firmware.

---

F.A.Q. Pre-aggiornamento

• Posso aggiornare il mio dispositivo anche se rootato o con recovery modificata?
• No, l'aggiornamento fallisce. Devi riportarlo stock per poter usufruire degli OTA.

• È meglio fare un ripristino dei dati di fabbrica prima di aggiornare?
• In genere non è indispensabile, ma eseguendolo si evita di andare in contro a problemi come lag vari o force close frequenti (vedi sotto).

• L'aggiornamento cancella qualche dato utente?
• No.. L'update non rimuove nulla dei vostri dati, a meno che eseguiate un ripristino dati di fabbrica prima dell'aggiornamento.

• Vorrei eseguire un backup totale prima di eseguire il ripristino. Come posso fare?
• Puoi farlo tramite Helium, che permette di fare il backup delle app senza richiedere i permessi di root. Qui la guida.

• Mi conviene fare l'aggiornamento?
• Dipende dalle tue esigenze.. Se non sei sicuro di quello che stai andando a fare, aspetta i pareri degli altri utenti.

• Non mi viene notificato l'aggiornamento. Perchè?
• È probabile che tu abbia un firmware di provenienza differente da quello posseduto dagli altri utenti che hanno già effettuato l'update, e che dunque non sia stato ancora aggiornato.

• Quando esce l'update per il mio firmware?
• Noi non lo possiamo sapere.. Appena sarà disponibile, vi verrà notificato in questo thread.

• Come posso conoscere la provenienza del mio firmware?
• Recati in Impostazioni → Info sul dispositivo.
  
  Descrizione completa sigle SKU:

  CHT (Taiwan, ChungHwa Telecom) SG (Singapore) CHS (China) WW (World Wide) TIM (Italy, TIM) RUS (Russia) HK (Hong Kong) TW (Taiwan) HK (Hong Kong) JP (Japan) UK (United Kingdom) CHT (Taiwan, ChungHwa Telecom) CUCC (China, Unicom)

• Posso flashare l'OTA di un firmware con SKU diversa da quello che monto attualmente?
• Assolutamente no, l'installazione si arresterebbe restituendo un errore, o peggio, un bootloop.

Thread aperto. Al primo post i changelog di tutti gli aggiornamenti. Nel post sopra di questo c'è scritto ciò che potete e non potete postare, vi prego di rispettarlo. I post inutili saranno eliminati senza preavviso e senza notifica.
Buon proseguimento.
