Nexus7 2013(Wi-Fi)にAndroidのFactoryImageをMacを焼いてみる

SDK Managerを落としてくる

Google公式で配布されている中からAndroid Studioが含まれていないものを落とす。

Android Studio と SDK ツールをダウンロードする | Android Studio

wget https://dl.google.com/android/repository/sdk-tools-darwin-3859397.zip?hl=ja
mkdir work
cd $_
mv ../sdk-tools-darwin-3859397.zip .
unzip sdk-tools-darwin-3859397.zip

sdkmanagerを使ってplatoform-toolsを落とす

cd tools/bin
./sdkmanager --update
./sdkmanager --list
# platform-toolsのインストール
./sdkmanager platform-tools

Androidの開発者オプション

Andoridの設定にあるビルド番号を連打して開発者オプションを表示させる。

開発者オプションのUSBデバッグを有効化する。

FactoryImageをダウンロード

Factory Images for Nexus and Pixel Devices  |  Google APIs for Android  |  Google Developers

ここから自分のデバイスにあうファクトリーイメージをダウンロードする。

ダウンロードしたら展開する。スクリプト(bat, sh)があるので中を見てみると単にコマンドが羅列してあるだけだった。

書き込み
