Hello guys, i have some weird problem with my phone. So, data connection on my phone cant work like usually. i have this problem since i flash wrong version of miui. My device is HM2014817, but i make some mistake and flash HM2014813 version. That's why my phone cant get signal.
But the main problem's not that. i flash true rom through MiFlash, but SIM 1 cant connect to data. When i switch data to SIM 2, its just can connect to Edge. I try to switch data to SIM 1 again and change Preferred Network of SIM 1 to 2G. Switch it back to SIM 2, and change Preferred network of SIM 2 to 3G. But, when i switch my SIM 2 Preferred network to 3G, its come back to 2G again and the preferred network setting force close.
I try to change Preferred network though *#*#4636#*#*. But same problem still exist. How can i fix this problem? Please help!
NOTE : DATA WORK FLAWLESSLY ON OTHER ANDROID VERSION ( L / MM / N )

Hi All,
I know its a topic which has been addressed differently in different threads. I am a user from India and have a GSM SIM. I have got a Verizon S4 phone. I tried using it with Vodafone SIM and get a problem in using it. Surprisingly a NOTE 2 from Verizon works just fine. I am able to use it for data with 3G but not able to use it for voice. Following steps have been tried already.
- Default Options of using Global Mode and GSM/UMTS ** Doesnt search the network at all.
- Hidden Menu Changes using # codes. ** Shows network but emergency mode only.
- Phone Info app to change the mode. ** Shows network but emergency mode only.
- RF Band change using the hidden menu. ** Shows network but emergency mode only.
It does say that it has GSM radio but cant be used for some software reason I suppose. I checked with Verizon Rep and was told that it cannot be used in India with a GSM SIM and would need the Verizon SIM only to connect with International Roaming.
I was able to install Wanam Lite I-9505 ROM on the phone and patch it with Loki-Doki patch and the phone was booting. But the network signal was not getting picked up. I had data connectivity but no voice or SMS. Is it possible to patch the I-9505 radio over to I-545 and / or force it use GSM as the primary modem.
Any idea for this?

Have you messed with your APN settings? I use a I545 with T-mobile here in the states and all I had to do was change the APN settings
So my lte/cdma mode doesnt seem to work at all, i know i have 4g but when i turn on my phone it says mobile network (under settings) connecting and then the mobile network type keeps flashing from lte to unknown, however if i i switch to cdma mode 3g works fine so does anyone know a fix to lte ? i already reflashed with odin and also restored and did all that (sm-g900r4) i also attempted to do a nanroid restore but that didnt fix it either :/

After reverting back from RR 5.8.0 to Stock kitkat my phone is not getting 3G/4G networks although I've activated 3G/4G plan. It's only catching 2G networks. Network drops regularly and phone goes to "no service' for moments. Any solutions?
Thanks in advance.
U might not have edited your APN settings.
Search on Google for APN settings of your sim operator, edit it and save it.
If your problem is solved plzz hit that thanks button..
No everything is okay... 2G network is working.. but not getting 3g /4g network.. when the preferred network is set to 3g only.... I restored modem files.. and flashed stock ROM through QDloader mode.. but nothing is solved..
Hi ,
This is about oneplus2 dual sim phone
I had used network signal guru (root) to lock lte band at 2300 in a sim slot after which i was unable to search for 2g networks in the other sim slot. So i had only 4g is other sim slot.
Now i am unable to search any 2g/3g network. all i get is no networks or error while searching networks
I tried clearing the network signal guru (root) settings . but no success.
I tried flashing a custom rom (RR 5.8.5) . but no success.
I tried restoring from nandroid backup but no success.
Please can some one help me how to restore the settings to default so that i can have 2g/3g in one sim slot and other should have 4g.
Please help
