Exclamation [Q] Freelander PD103GS customRom

Hello Team,

I bought this Freelander PD103GS. It has Dualsim and a function that I can call to other persons.
Here is a website from which i bought this Thing from Efox-schop.com

it has 1024*600 Android4.2 7'' Dual Core 1.2GHz MTK8312 Bluetooth
At first this machine works very great. But i missed the function landscape in a call.
so I want to switch of the phone.apk and phone.odex,
but i deleted this two files.
so i want to flash a custom rom for this machine.
I can do that only with the function apply update from SDcard

so can everyone please help me.
I have no chance to connect with my pc. I only can take the SDcard in the SDCard-slot of the PC.

Thanks in advance
