我购买了一台 32GB 的 Nexus 7 平板电脑（flo），并在这里找到了安装 ubuntu-touch 的信息：http://developer.ubuntu.com/start/ubuntu-for-devices/installing-ubuntu-for-devices/
我安装了 phablet-tools 和 ubuntu-device-flash，我的设备在 adb 和 fastboot 中都能正确识别：
user@*****:~$ adb devices
List of devices attached
0498b5** device
user@*****:~$ adb reboot bootloader
user@*****:~$ fastboot devices
0498b5** fastboot
这是解锁后引导加载程序报告的状态：
PRODUCT NAME - flo
VARIANT - flo 32G
HW VERSION - rev_e
BOOTLOADER VERSION - FLO-04.02
LOCK STATE - unlocked
我正在尝试使用命令 ubuntu-device-flash --channel=stable --bootstrap（作为用户）安装稳定版本，这是我在终端上得到的结果：
user@*****:~$ ubuntu-device-flash --channel=stable --bootstrap

此时，我的平板电脑（进入基于 Ubuntu CWM 的恢复模式）按预期重启，但从未进入恢复模式，它想正常重启，但卡在了带有 ubuntu 徽标和下方加载栏的启动循环上。
到达这一点后，我尝试的下一步如下：
为脚本文件分配执行权限：
user@*****:~$ chmod +x /home/user/.cache/ubuntuimages/ubuntu_commands937086177
手动重新启动平板电脑进入恢复模式，并启动命令来运行之前留下的脚本：
user@*****:~$ ubuntu-device-flash --run-script=/home/user/.cache/ubuntuimages/ubuntu_commands937086177

有人能帮我完成这个吗？只要我能尝试，我真的不介意安装 13.x 或 14.x。
在我的笔记本电脑（也就是我用来刷新的机器）上，我运行的是 Ubuntu Saucy x86_64，我担心我的问题是由于 x86_64 架构造成的，但我在互联网上没有找到有关该问题的任何信息...
