XT926, sim card problem

Hello all,
I recently got the XT926 from Ebay. The phone had CM 10.2 ROM installed when I got it and it could detect my SIM card. Everything worked almost fine. I was able to access the internet through HSDPA and I was able to make calls. However I had issues with not being able to send SMS and MMS. I couldnt save the SMSC number so I decided to install the stable release of CM 10.1. I wiped, and flashed CM10.1 using TWRP that already existed in the phone. Now, after that, the phone will no longer detect any SIM cards no matter what operator or ROM I use. I live in Sweden and I'm using the GSM network. Wifi and all other functions work fine.
I even installed the official VRZ_XT926_9.8.1Q-79-1_CFC.xml but still its not able to bypass the activation screen because it wont detect any sim cards.
Any idea or suggestions on how to fix this?
Thanks in advance

[Q] No LTE after Lollipop update

hi guys,
I flashed the factory image of Lollipop to my Nexus 5, everything seemed well and dandy until I took my T-Mobile SIM card out and installed my AT&T card. No lte even though my apn is set to it.
Anyone else having this issue?
I've never had a problem getting LTE after flashing any of the lollipop builds (preview or official). Was your phone off when you swapped sim cards, or did you reboot it after the swap if it was on?

I had a similar problem until I updated my Profile and PRL. Updated both after flashing to lollipop and I was up and running

[Q] China Unicom 3G not working CM12OS

Hi everyone,
I bought my OPO in China last december and I have China Unicom as Service Provider.
I have correctly installed offical CM12OS, but the 3G network is not recognized by the modem of the ROM.It goes only on the 2G Network.
It is the same that happened with CM11s, In that case I had to flash a modem("signed_modem_34g.zip") into the Rom and then it worked.
I tried flashing "signed_modem_34g.zip" on CM12S but I was stucked in the bootloop.
What could I do now to make the 3G working again?
Thank You so much for the support.

nightmare trying to get CM12 to boot on 4g XT1039 - no calls but data works on stock

Hello all
I recently got a Moto G 4G XT1039 in the UK which was on the o2 network, which I've unlocked.
I want to use my Three network simcard, which works fine on stock firmware, BUT the baseband is o2's one, so with my three sim card the data works, but calls doesn't "mobile data not available" so...
Can I flash a stock standard baseband?
I've tried unlocked bootloader and installed CM12 but it get stuck in bootloop at the cm animation, so i've restored to stock... I'm oblivious what to do next?!?
Any help would be appreciated...
I just want calls to work!
Thanks in advance.
Ok i've read I need to intall cm11 first to get it to boot as cm12 just stuck in boot animation but for the life of me cant find any cm11 download links, anyone know any?
Thanks
Hi, please help, moto g xt1039 works fine on 2g calling.. but when select 3g or lte,
it doesn't connect call, always call ended automatically.. any solution please..??
Did you ever update the phone to 5.1 stock ?, if so it should work fine. If however you went straight from KitKat to CM12, that's your problem, the radio firmware needs to be updated. Links to it are in the stock image threads on this board.

Snapdragon S7 in India

Hi
I got Verizon S7 which came with Marshmallow. Other than VoLTE everything worked fine until I flashed Nougat update. Few days ago I upgrade the firmware to official Nougat and now the data has stopped working.
With Idea sim - Calls, SMS fine but no Data
With Jio sim - Network detected but calls disconnects immediately, no sms, no data.
I tried going back to Marshmallow firmware where it was working fine and I am facing same issue on Marshmallow too.
I have set network modes, APN settings correctly nothing wrong there. How do I fix the issue?
------
SOLVED: Flashed T mobile firmware and it fixed the issue.
