No WCDMA support in CM12.1 ?

Hi,

I have tried 2-3 unofficial stable builds of CM12.1 with 5.1.1 for Samsung S3 i9300. The phone works perfectly fine with this build except that it does not connect to 3G WCDMA. It continuously shows 2G only. Also, the APN settings show for bearer only (LTE, eHRPD and unspecified).

Is this build that am trying by any chance only for CDMA2000 or cdmaOne only? or LTE only?

Otherwise, the phone works perfectly fine.

Please help .

Is WCDMA IMT-2000 the same as IMT-2100 ?

Hello there!

My "GiONEE Pioneer P2M" when enter to Engineer Mode gives me the following bands: GSM (GSM850, EGSM900, DCS1800, PCS1900) and UMTS (WCDMA-IMT-2000, WCDMA-PCS-1900, WCDMA-GSM-900)

But instead of WCDMA-IMT-2000 it's mentioned: WCDMA-IMT-2100 on websites ? are they the same ? will it cause a carrier registration issue ?

WCDMA Only Mode Reset After Reboot

This thing is literally on every 5.1 ROM, any solution?

ZR does not get coverage in WCDMA mode.

I'm looking for a solution to ultra frustrating problem I encountered after performing OTA lollipop upgrade from kitkat. My network coverage gone after lollipop upgrade, I can't make calls or send messages. While I played with settings i found that with in Preferred network type there are three options as below.

WCDMA Only
GSM only
WCDMA (preferred)/GSM {Default option}

It was set to 3rd option. When I changed to GSM only option my calls and sms started to work flawlessly but as you all aware Internet was on 2G(Edge). To get HSPA working as far as I know I have to use WCDMA in xperia phones (Not to be confused with CDMA). When ever I switch to WCDMA my coverage goes off.. I can't make calls. So i end up using the phone in GSM only mode and made a thread in official xperia site as below. I also tried repairing using PC companion and resetting the phone no avail.

As you can see one person with the ranking of moderator acknoledged the issue and suggested me to revert it back to Kit kat until the fix has been made. I tried flashing using flashtool still problem exist. Even in old kit kat firmware which i was using it for long time with out any issues. I think some thing has happend to my mobile after lollipop upgrade.

Yesterday I unlocked the boot loader and flashed Cynogenmod 11 as well.. Again same problem. WCDMA does not work thus no 3G. Now I'm using Sony official lollipop firmware by flashing via flashtool.. I ended up using my phone in GSM only mode (Edge).

Any suggestions? Ideas?
