Phone : LG K7 (K330) T-Mobile
Chipset : Qualcomm MSM8909 Snapdragon 210 (LTE model)
I tried to follow these guides : http://forum.xda-developers.com/z3-compact/general/guide-unlock-z3c-international-bands-t3091344 & http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269 in order to unlock all 3G & 4G bands because the phone was bought in US and now I'm in Europe.
The initial state was that phone could only operate at 2G networks in Europe.
I tried several combinations on the enabled bands, like all of them enabled, only the European ones, only a few etc etc but nothing worked. The phone could not detect the SIM at all, or at some occasions it was in a loop trying to connect and was showing the "welcome to <carrier>" pop-up without actually managing to connect to the network/cell at all. Even when all bands were enabled, the phone could not operate even at 2G network (that was initially working).
(I have checked after reboots etc that the new NV values are saved as should).
At all these failing states, the process qmuxd was running continuously at 100% cpu (if this info is at any help)
Now, I reverted it back to US bands, and it operates at 2G
My question is: since the chipset (as mentioned at its specs) can operate at these bands, shouldn't it work? Is there something else I should have in mind, that maybe prevents the phone/antenna from operating at European bands?
Thanx in advance
