New Dragon Reward for DC Android - Elements Dragon

if i got spec. cool fire from login, will i not be able to get elements dragon?

No, you won't be able to get it at the present time.  It is only for new mobile accounts.  So far I only know of Android players who have received it.  

What if you uninstall your game and reinstall it? Or if you have an Android cell phone and then install it on your iPod touch or some friend's iPhone?

Konami, you can try it and see if it works...but I would be careful.  It may not work for established accounts unless they were only playing on PC before.  That is the purpose of promotions like these.   You don't want to end up losing your game.  

Okay, I was finally able to confirm that this is the reward for both iOS and Android.  It replaces the Special Cool Fire Dragon as the reward for playing on a mobile device.  

If it did finally replace the reward for the Special Cool Fire Dragon for iOS, is it possible for me to still get the Elemental Dragon if I already got the Cool Fire Dragon?  I tried re-installing and it didn't work.

And is it possible to get the Elements Dragon after getting the Cool Fire? Will it work if i re-download the app?

If you really want to find out, you can try to re-install the game yourself.  I can't imagine it would take too much time.  It's not like anything I said would help you.
