Need guide to upgrade XDA from WM2003 to WM2003SE

[irsan_donald]

Please guide me....
I have XDA Wallaby with ROM v4.01.12 ENG and radio v4.16.00
Can I upgrade it directly to WM2003SE by running the .EXE file I got from ROM Kitchen ?? Or should I have to downgrade it first to PPC2002 ? My BOOTLOADER version is 5.17
Does the new WM2003SE ROM compatible with my region ? Indonesia (ASIA). Thanx...
