Need help on Lenovo A388t(edited build.prop in windows) URGENT

[kevybeast]

Hey guys, I wanted to change hostname in my Lenovo Device, So there was a tutorial at here

http://nileshgr.com/2012/10/13/how-to-change-wifi-host-name-of-your-android-device

1. Note that the device must be rooted to use adb
2. Run adb pull /system/build.prop
3. Edit the build.prop file and append net.hostname=NewHostname
4. Run adb push build.prop /sdcard/build.prop (or /mnt/sdcard, if it fails)
5. Run adb shell and execute the following commands:
   $ su
   # mount -o remount,rw /system
   # cp /sdcard/build.prop /system/build.prop (or /mnt/sdcard if you used that previously)
   # mount -o remount,ro /system
   # exit
6. Reboot the device

So now after doing this, I couldn't edit file in it then I used adb push build.prop in my sdcard and then edited it in windows then I couldn't find net.hostname so I added it and then I saved and then replaced it with the /system/ one with this using file explorer(ES File Explorer) then rebooted after doing other things using the shell and stuck at boot loading...
I have downloaded over 3 custom/stock ROM of my android and whenever I try to flash em it makes a folder PacFiles and does everything but it dosent flash my android.. Idk why, I have connected USB and it is not started and the mobile shows the battery charging image like

A battery come which is filling and shows 35%,,
My android starts, showing its G3 sign then it disappears(like normal, boot image) and then black screen, Then something happens like something is gonna view(screen changes color to light dark or something like that) then black again and then it keeps repeating excluding the starting sign(couldn't boot)
I have its original build.prop which was made when I used adb pull /system/build.prop as you can see in the steps above, I found it and made 50 copies of it in a folder..
Now the problem is
I want to push it in the /system/ folder,, PLease help
I know the adb push command and the device is connected to the laptop and showing charging thing which is filling up(phone aint charged)
But when I use adb push or any adb shell command now when its not started, It says no device found..
I also have root explorer, It can't find the device too..
