速報：った大変だぁ〜Android Mの罠 on Nexus9(Wi-Fi)

先日ニュース記事に書いたとおりNexus9(Wi-Fi)にAndroid M previewを入れてみました。
とりあえず確認したかった事は確認出来たのでAndroid5.1.1のファクトリイメージを焼きなおして元に戻そうとしたんですが…　ｸﾞﾜｧ━━(;ﾟДﾟ)━━ﾝ!! 元に戻せません。まっまさか文鎮化？漬物石化？シクシク(泣)

ファクトリイメージは「Factory Images for Nexus Devices」から落としてきたAndroid5.1.1(LMY47X)も、Android5.0.2(LRX22L)もだめです。それより前のは試してないけど。
