Hello everyone , i really need your help.
After trying to enable 4g+ on my xiaomi mi a1 i am left with an awkard situation. All i did in qxdm was changing the value of rfnv lte b3 ca cb config ..but being stupid at that moment i forgot to write down the default one .
On slot 2 ...everything is ok .
On Slot 1 ...i have 4g ..i can send and receive sms , i have internet connection but i cannot make calls .
On *#*#4636#*#* the voice network type is set to LTE, and it doesnt change from 4g to 3g when trying to make a call. And since my network ( vodafone romania) doesnt have voice over lte i cannot make calls from slot 1 .
If i try to change the network type from 4g to 3g ..i lose signal .
Any help would really be helpful .Thank you in advance.

Hi I have a L720 and made him sprint sim unlock, I'm using it in Argentina with the "claro" position the company APN and it works, sign up both 2G and 3G and the mobile internet works fine. however my question is this, in the menu of this phone does not let me change mode, GSM / UMTS network can not choose one or the other, I can only make it automatic, it is not a stock ROM that lets me choose 2G or 3G. can this be changed? or stays like this forever? I need to use that in my area 2G 3G works very poorly and do not come calling me ..
from already thank you very much.

Recently I got a 4G sim specifically JIO. It seems to be working in other phones but doesnt in yureka. I can see the JIO network but cant connect to it. I have tried the *#*#4636#*#* route but to no avail. I have used the profiel route too. I have notices that everytime i change the network to lte only from the phone information and change the network type to lte(preferred) the radio changes back to lte/gsm auto(prl). Please help me. Thanks in advance.

Have you tried to change nertwork mode to WCDMA only or GSM...or both WCDMA and GSM...????
Hi bro I am from Pakistan too so I research on it (couz I got 4g phone as well) I tried zong and didn't received signal so what I found is that these networks are on limited bands to work u need both phone and network to be same frequency supported to work 4g (and don't ask me how to do it couz I don't know either) try using warid (if possible) 4g it probably gonna work (not sure) or maybe you are not in 4g coverage area....
last night I tried to switch to another lte band by dialing *#*#4636#*#* , I don't know what band I chose , now no 2g or 3g bands and just one sim card works at a time and the one works only on LTE band, so since my operator doesn't offer volte I can't make calls and even receive messages. I found the proper qcm file and flashed it with qpst software successfully but nothing happened. any one have an idea what to do?
