Well, the error is there for a reason. Sure, you can ignore the error and 
proceed anyway, but if you have to ask how to change the behavior of the 
script, I'm not sure it's a good idea to tell you ;p. Nobody wants to see you 
brick your device.

My english is bad, sorry. I want to compile the folder back into a bin.. 
I mean with "ignore this message" .. why is ./build-ng.sh [-nopad] not working 
fine?

Because padding is not the cause of the extra size. Either the files you added 
increases the size, or the arrangement and/or compression of the files was 
inferior to the original build.

Given the size of the original firmware, there is a good chance your device has 
4MB FLASH ROM. That means the effective maximum size of the firmware is 
4MB-[boot loader/other] .. so less than 4MB. If you try to flash a firmware 
larger than that, the device will not accept it, or be bricked.

The scripts are easily modified to remove this restriction, if you are sure 
your device will accept a larger firmware.

The better thing to do would be to remove unnecessary components of the 
firmware in order to reduce its size.
