My device is Lenovo A1000 Android 5.0 Chipset SC8830.
My device has local build S113. I want to change build to official ROM build S30666. I tried to flash ROM build S30666 to my device but failed. I extracted both pac files and found some files are same and some files are difference.

ROM Build S113

Unlock SIM

ROM Build S30666

PAC Extracted

I did not upload "system.img" due to it big size.

I wants to replace some files and repack agian but I does not know how to do. Which one is right?

Edit "SC7731_UMS.xml" file build S30666.
- Change FDL1 to "0x50003000" same like build S113.
- Delete all "WIFICal1"
Copy "sign" files from build S113 to build S30666.
Then repack pac file and flash new pac file.
or
Edit xml file build S30666.
- Change FDL1 to "0x50003000" same like build S113.
- Delete all "WIFICal1"
Then repack pac file and flash new pac file.
and
How to repack "unlock sim" to new pac file?

Please advice me.

Please advice me.

since you can already extract, see https://www.hovatek.com/forum/thread-1232.html for how to create pac file (you should start from step 11)
BTW what error did you get when you tried flashing ROM build S30666?
cos you might still land on the same error even after repacking

from all indications, it seems you have already been replied 
there is no use trying to combine the files from both firmwares, the result will at most brick your device OR even if successfully, some functions may not work.

Why my device can not flash with official ROM? Hardware lock? I can not success flashed twrp too ( stuck on boot logo screen) due to my ROM is not official ROM. Right?
I would like to install custom ROM. I need twrp for my device build. How can I do for this problem?
