w880 flash error - unsupported phone

My w880 had software reinstalled online using SE Update Service after it wouldn't switch on. However, it installed Baltic languages instead of Chinese which was on it before. I wanted to install Chinese language (Hong Kong) using xs++v3.1. Followed the instructions from one of the guides on this forum. This showed up when I connected the phone:

20:07:25| Profiling SEMC phone...
20:07:25| Platform: DB2020

I downloaded the following files to flash:

W880_R8BA024_FS_HONG_KONG_RED53.fbn
Ai_i_CDA102719_15_R4A_Generic_Trade_Hong_Kong

This came back when I started the flash:
