Can anyone identify these SE P900 files?

[thewizard-oz]

I have 2 SE P900s - one ex-Orange UK branded phone and the other is non-branded.

I connected the non-branded one to my DSS-25 and ran SE's Update Service last night. Update went well but what I would like to know is what type of files are the 19.6MB of files that SEUS downloaded to my PC to do the update?

The file names and sizes are shown here:-

Sony Ericsson Update Service downloaded P900 files
=======================================

HL1_12529_030912_1435_R5D (146KB)
HL1_162021_000000_0000_R5B02 (12.6MB)
HL1_162022_000000_0000_R3D011 (873KB)
HL1_CDA1620035.bin_000000_0000_R5A07 (4.79MB)
HL1_CDA1620035.img_000000_0000_R5A07 (1.17MB)

Are any of these files AVR, ARM, GDFS, SBN or other flash files?

By the way, the firmware in the updated P900 is:-

Phone: CXC162022 R3D011
Bluetooth: CXC12529 R5D
Organiser: CXC162021 R5B02
CDA: CDA162003/5 R5A07

Thanks,
