Je viens de faire toutes les étapes nécessaires sur mon N7 :
- Téléchargez l'image d'usine à partir de Google
- Décompressez le fichier téléchargé (par exemple par
tar -xvzf nakasi-jdq39-factory-c317339e.tgz )
- Démarrez votre N7 dans le bootloader (maintenez les boutons d'alimentation et de volume enfoncés).
- Ayez fastboot installé (livré avec le SDK ou pour Ubuntu, il suffit d'installer Android-tools-fastboot )
- le connecter à votre machine
- Flashez-le en utilisant flash-all.bat o flash-all.sh (nécessite l'installation de fastboot)
Voici la transcription (sous Ubuntu) :
me@localhost:/tmp/nakasi-jdq39$ ls
bootloader-grouper-4.18.img flash-all.sh image-nakasi-jdq39.zip
flash-all.bat flash-base.sh
me@localhost:/tmp/nakasi-jdq39$ bash flash-all.sh
...
