一臺海思芯片的設(shè)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(jī)后卡在開機(jī)動畫處，進(jìn)不去桌面。TTL查看data分區(qū)是空的，沒有任何內(nèi)容。有大神指點一下是哪里的問題嗎？
此機(jī)沒有recovery模式，輸入reboot recovery重啟后還是正常啟動進(jìn)入開機(jī)動畫，無法執(zhí)行雙清。找了各種所謂的恢復(fù)出廠設(shè)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(shè)備可進(jìn)fastboot模式。但是沒有找到相關(guān)命令，命令如下

請教大神指點，如何才能實現(xiàn)那種恢復(fù)出廠設(shè)置后啟動設(shè)備讓它自動配置所有的參數(shù)【這些配置的參數(shù)會自動生成到data分區(qū)里】
找臺好的機(jī)器備份data分區(qū)的數(shù)據(jù)恢復(fù)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(jī)器。
