Can this phone be forcibly network-unlocked?

Elephone P9000. The bane of my... week. Sitting there, smiling at me with its beautiful screen, totally unusable.

Quote:

Wrong PIN - Please enter the Privacy Protection password to unlock.

The PIN from my SIM card, doesn't work. Also 1234, 0000, 8888, 123456, 000000, none work.

I removed SIM card and reboot. Still get the lock screen to enter PIN and error message "Wrong PIN - Please enter the Privacy Protection password to unlock".

Edit: wrong forum - sorry! Mods can you move it to the P9000 Q&A forum?
I managed to eventually get to the stage where I could flash it with a new ROM, so I've just done that (very pleased)...

... and still see the network lock when I start it up.

So where to next in the unlock saga?

• I've tried the local phone repair shop, had no clue


• I've tried flashing a different ROM, has no effect on network lock.


• Vodafone, my carrier, seems to only unlock phones they've sold.


• The dodgy online unlock sites don't even list Elephone as a manufacturer


• Elephone themselves don't like to answer support questions.


• The seller is unresponsive.


• I've no idea what network it's locked to.

I don't know what to try next. Can this phone be forcibly network-unlocked somehow?
