一臺海思芯片的設備，使用hi tool全分區(qū)備份后搗鼓研究，刷了其他的固件，最后再刷回備份的全分區(qū)文件，開機后卡在開機動畫處，進不去桌面。TTL查看data分區(qū)是空的，沒有任何內容。有大神指點一下是哪里的問題嗎？
此機沒有recovery模式，輸入reboot recovery重啟后還是正常啟動進入開機動畫，無法執(zhí)行雙清。找了各種所謂的恢復出廠設置命令也無效，如下
console:/ # recovery --wipe_data
/system/bin/sh: recovery: not found
126|console:/ # am broadcast -a android.intent.action.MASTER_CLEAR
cmd: Can't find service: activity
設備可進fastboot模式。但是沒有找到相關命令，命令如下

請教大神指點，如何才能實現那種恢復出廠設置后啟動設備讓它自動配置所有的參數【這些配置的參數會自動生成到data分區(qū)里】
找臺好的機器備份data分區(qū)的數據恢復到這臺這種操作暫時沒法操作，因為手上沒有第二臺一樣全好的機器。
