[Q] Help with LG Prada 3.0 (KU5400 version)

Hey guys,
I need some help with my phone. After stupidly installing the P940 LG Prada 3.0 ICS found here: http://forum.xda-developers.com/showpost.php?p=28568521&postcount=8 , my KU5400 Prada is now stuck in an "Encryption unsuccessful" screen that i have never seen before, with the option to reset phone. The only problem is : the touchscreen would respond. The phone didnt hang as i am still able to increase and decrease the volume.
I have tried everything found in this forum : http://www.tinhte.vn/threads/1253753/ (its in viet : I used google translate) and while i am able to reach S/W Upgrade mode, it wouldnt flash any rom EXCEPT the P940 ICS rom. Every other rom either results in KDZ crashing or LG Support Software reaching 7% and suddenly stopped detecting the device.
I tried LG Phone Recovery but it says that my model is not supported (trying with Singapore, Europe, Italy and Korea as the stated country).
What can i do?
Thanks!
Same on LG KU 5400 with European V20D.00.kdz

help needed
Hello,
I have done something to my Prada, with the calls and now need a help. The case is the following: On the call options when you try to dial there is a grey window pop up asking you if you wanna do this call on skype, viber, mobile etc. This grey window is now missing and calls directly goes on mobile. Does someone knows where is the option to make it come back?
I am really sorry if I am writing in the wrong place but can`t really find place where to ask somebody. Many thanks in advance

Need Help with mostly dead LG Volt

My LG Volt had been freezing frequently and I would have to restart the phone .The last time it froze it would only turn on to the LG logo. I can get in to recovery and did a factory reset , a couple of times, but that did not help. I have looked at a number of forums at various sites trying to find a way to root this and hopefully restore the phone. One problem is that the computer does not recognize it. Any help would be greatly appreciated ! This LG Volt is running android 4.2 . It came with it . I was sent a replacement phone last Feb. but I know it was still android 4. . :crying:
