Nella serata di ieri è stata rilasciata la CM20120216 che si presenta con un'importante novità: la versione di base Android 4.2.2 Jelly Bean con un corposo changelog che potrete vedere alla fine di questo articolo.
Inavvertitamente ho installato questa Nightly senza fare un backup della versione precedente ma tutto sommato non ci sono stati grandissimi problemi. Qualche bug c'è soprattutto in fase di avvio mentre oggi dopo aver installato la versione del 17 febbraio ho dovuto fare i conti con una schermata nera fissa all'avvio e almeno 5 minuti di panico nel vedere una (per fortuna solo momentanea) impossibilità di procedere al nandroid restore.
A cosa sia dovuto questo temporaneo down del mio fido Galaxy Nexus non posso saperlo con certezza, tuttavia ho buoni motivi per credere che il problema sia dovuto alle modifiche del boot animation. Nel momento in cui scrivo sto effettuando un lentissimo nandroid restore. Qualcosa è andato storto quindi in tutta sincerità non mi sento di consigliarvi il flash di questa custom rom o almeno non la versione di oggi.
Il team Cyanogenmod sta sperimentando: lo ha fatto con l'animazione di boot e con una nuova funzionalità/bug perché ancora non ho capito l'utilità di rendere adb compatibile solo con l'ultima versione dell'SDK. Secondo il team si tratta di una sicurezza in più ma per quanto mi riguarda si è rivelato solo essere un fastidio in quanto ho dovuto necessariamente scaricare di nuovo e installare l'SDK (che tra l'altro viene fornito senza platform tools). Seguirà tra l'altro una guida per installare l'sdk completo su Linux. Per accorgersi se l'SDK è vecchio basta aprire il terminale dalla cartella platform tools e digitare adb devices. Se vi verrà fuori una sequenza di numeri e la scritta offline dovrete aggiornare l'SDK.
La versione del 16 febbraio invece è buona: qualche lag iniziale c'è ma dopo due o tre riavvi le prestazioni sono uguali ad Android 4.2.1. L'autonomia, ottima era, ottima rimane. Resta da capire la causa della schermata nera dopo l'installazione della Nightly del 17 (che sia stato un pacchetto corrotto?). Qualunque cosa decidiate di fare FATE PRIMA UN NANDROID BACKUP!!!
