OH2 Room for P900 can't flash into my device

[fromvoid]

Hey guys, I just bought P900 in Melbourne and it came with 4.4.2 OC1 Room. I have some strange error with it when I'm trying to flash the latest room P900UEU1COH2 into it . hope someone can help me !! Thx a lot!
Here is what I did :
1. Flashed the Netherlands Lollipop room P900XXU0BOF2 to get lollipop upgrade. But the Bluetooth didn't work
2. Tried to flash cellular south OC1 to get this upgrade for bluetooth bugs, but failed.
3. Flahsed back to P900XXUAOC1 and succeed
4. tried to directly flash OH2 over 4.4.2 but still failed

Now please someone tell me what to do to get this lollipop working?! it's driving me crazy.....

thx guys anyway.

See this post http://forum.xda-developers.com/showpost.php?p=62474015&postcount=19 - you'll need to downgrade to Kitkat first then flash the Lollipop ROM

You can do this option, load BL, AP, and CSC in Odin, assume you already have AP OH2 for US region.
Here is the 2 files BL, CSC you may need, they comes with AP OH2 of US as a set, don't use with other APs.

I rarely failed flashing when all three files are loaded in Odin.
