Question [Q] [help]how to get system folder permission for hdx7

I just play andorid device a few days, but My hdx7 is a little bricked because i deleted some system app. Now I can log in fire os, have adb, usb connected and internal storge, even i can operate device setting app, but i can't open the other app because i don't have a desktop.
I compare system/app folder with the same folder in the amazon bin, found that the folder lack of scores of app, but the other system folder is the same. So I hope can adb push app folder to the system folder, but the pemission denied. I try to remount or mount, it can't work.
if adb root, then "adbd cannot run as root in production builds.
if adb push apk to the app folder, then “permission denied".
if adb remount, then ”remount failed: Operation not permitted".
and I have try adb shell like that:
# su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# chmod 777 /system
# exit
it didn't work.
my hdx7 have rooted.
My Questions are:
1. If I could push the app folder to the system folder and reset to factory, is my hdx saved?
2. How to get the system folder rw in the situation?

thx for any prompt, although i am a rookie but i will try my best, i wish the adept can help me and will be enormously grateful. Sorry for my poor english.

It sounds to me that you had lost root.

Hmmm... It says you still have root (the prompt changed after "su")

I personally don't use ADB much. I have Root Explorer (grabbed it legally for free from Amazon ages ago) and Wifi Explorer Pro (same method) so I basically WiFi myself the files I need sideloaded then move them around on the device itself. But if you've lost launcher, you have deeper issues.

Have you tried ADB push any launcher? Or even a download store like 1Mobile or Aptoide?

ADB is basically a Linux shell debug into Android, so you need to learn some Unix shell commands. I'm sure you can find ADB guides with the basic commands, like "ls", "cp", and so on.

You need to check the directory and see if the system/app and other system directories are still there. This is one reason I only play with the copy of ROM I have (see Safestrap Recovery).
