I tried installing CyanogenMod on my friend's Optimus Hub, and I dramatically faced what someone called the "Funny SIM" problem: in simple words, it is impossible to save APNs, and so data connection is not available.
This, as my research suggested, is a compatibility problem between Hub's CyanogenMod and some SIM cards, the 128k ones. In fact, using a 64k sim made APN and data connection instantly work.
The problem is that my friend's telephone company told him that he can't keep his number downgrading to a 64k SIM, so he would have to change his number in order to have 3g/H working, and that would be a big issue to him.
My searches led me to this thread http://forum.xda-dev....php?t=1444328.
This is about Optimus One, and the problem seems to be the same, but the flashable zips in the thread seem to SOLVE their problem.
I downloaded and opened the "Funny-SIM-Fix-OldBB" .zip and had a look at the changes it made:
It replaced some libs and made modifications to build.prop.
I am not very expert in this, but tried replacing CM libs with the stock ones, using the names contained in the .zip I previously downloaded to locate them and then rebooted but nothing changed. APN were the same.
So, Is there someone who tried something else, or is willing to try now?
Thank you for your attention!
