Do you happen to know where I can find a Douglas rom?
Did you do the full stock procedure or did you use the fix I posted later?
About your question, step-1 and step-2 only use adb to communicate with the device, while bootrom uses an entirely different protocol.
Also I don't use Windows, so not muc...
If your device are rooted install root explorer and go to system then priv-app you make new folder and name it as same your apk name then open it and put your apk there then change permission to rw-r-r may be this can help you i hope that
