Latest i9505 modem version for Philippines? topic

My current modem is XXUEMKE and have installed the GoldenFinger. But I'm having problems with connectivity, it's quite slow compared how other devices use it and when it gets to 15% battery and lower, it cannot connect to mobile data anymore. Yes, it has H+ on it but doesn't connect. When I turn off the mobile data, it cannot get any mobile data signal anymore especially when it's lower than 5%.

I have searched this thread: http://forum.xda-developers.com/show....php?t=2192025 and found modem versions for i9505. What I'm asking is if these latest version works good for Philippines:
XXUGNG1
XXUGNG2
or
ZHUDMI1
ZHUFNB3

And are there any zip files to flash it via recovery?
TIA
