Currently I on 4.0.3 stock rom (rooted, unlocked, firmwork 188.8.131.52). I want update to stock rom 4.2.1 (firmwork 10.6.1.14.8).

"I have bootloader (2.10 e) released by "US_EPAD-184.108.40.206-20120907" A03. I have rooted and unlocked from 4.0.3. I have partitioned a 32GB microSD with GParted to these two partitions 13GB Fat32 and 16gb ext4.
I have CWM-based Recovery v220.127.116.11.
When I try to install the 10.4.4.25 US Jelly Bean Bootloader, I received this message:
