interessante.. che vantaggi con questo kernel a parte gli script? che tipo di script sono consigliati esempi?

Oltre al fatto che lo sto migliorando per rimuovere quegli odiosi lag che ogni tanto (sempre piu spesso con un uso intenso) gli script farò una lista di quelli che consiglio, già belli e pronti da mettere nella cartella, tipo dare priorità al launcher (non l'ho messo direttamente nel kernel in quanto non tutti possono usare il medesimo launcher).

Aggiorno con la build 8 che porta ulteriori aggiornamenti, purtroppo tengo aggiornato il post su xda, qui riporto per cui ogni tanto capita che non siano allineati.

Build 9 online. Aggiornate il vostro kernel.

ciao come faccio a capire se e stato installato correttamente?

[tonno91]

molto interessante lo provo requisiti rom miui ..quindi anche una sviluppatore non stabile non dovrebbe avere problemi?

ciao come faccio a capire se e stato installato correttamente?

Ti trovi la cartella /system/etc/init.d/ e comunque hai ragione, mi devo inventare un modo per mostrare in modo facile la versione installata, magari metto un file in /system/ con dentro delle info Grazie per il suggerimento!

molto interessante lo provo requisiti rom miui ..quindi anche una sviluppatore non stabile non dovrebbe avere problemi?

Funziona su qualunque miui rom, anche la smiui, il kernel di base è della stabile 7.1.1.0 (china e global hanno lo stesso kernel).

@Namaless è normale che dopo cancellato cache e dalvik al riavvio appare come prima installazione la barra miui.it?

[note2now]

successo anche a me... cmq non ho notato miglioramenti e ho perso il root cavoli... quando cerco di abilitarlo mi da un errore con la scritta in cinese.... lo fa anche a voi?

@Namaless è normale che dopo cancellato cache e dalvik al riavvio appare come prima installazione la barra miui.it?

Si, è normale.
Anche non installando alcun file .zip da recovery, se esegui i wipes di cache e Dalvik cache, al riavvio, vedi l'installazione con la barra di avanzamento miui.it

Build 9 online. Aggiornate il vostro kernel.

Domande:
1)ma per tornare al kernel stock? Come devo procedere?
2)un backup da TWRP, prima dell'installazione del nuovo kernel, mi protegge da eventuali errori durante l'installazione del nuovo kernel? Posso usare il backup per ripristinare le condizioni funzionanti di prima?
