[Add-on][06/07/2012] [V.2.1] T-Mobile Wifi Calling for CM9/Andromadus/AOKP ROMS

---

T-Mobile Wifi Calling for Vision
Radio 26.13.04.19 required for this to work properly.

Update: All in one updater no longer requires lib-ril and gps .so updater to be flashed.

IMPORTANT UPDATE: Update to Version 2.1 Why? I have done some research on flashing radio images and found some interesting information. Apparently there are 2 files that pertain to radios in the RUU releases, a radio.img and a rcdata.img. We all have been flashing only the radio.img file but the rcdata.img contains further carrier information that directly relates to information in the build.prop file. I have put together a new 26.13.04.19 radio zip file that contains both the radio.img and the rcdata.img. The .img files were taken directly from the latest T-Mobile RUU release. This new radio/rcdata zip needs to be flashed through bootloader just like you flashed a radio in the past. As usual, you''ll need to rename the zip file to PC10IMG.zip before you reboot into bootloader. Check the MD5 Sum after you download the file to your sdcard to make sure it matches the following:

I have also updated information in the build.prop patcher with the proper information to match the information in the rcdata.img. This is now Version 2.1. After you flash the radio/rcdata img from the above link through bootloader, download the latest version 2.1 and flash through recovery along with the EFS wipe.

Update: Some users have reported that they have received SIM card related error messages. I highly recommend upgrading your SIM card to the latest TM9177 version if you are running any other version SIM. The 9177 version is what is currently shipping with the newer T-Mobile devices pre-loaded with ICS operating systems. I have this SIM card installed in my G2 running the latest Andromadus test builds by Flinny and it's working perfectly with no errors.

I have put together a working T-Mobile Wifi Calling Add-On for Vision devices running the latest CM9/Andromadus/AOKP ROMS and the latest T-Mobile radio firmware 26.13.04.19. I confirmed this working with the latest T-Mobile .19 radio. This add-on will also update your radio lib-ril and gps .so files for better performance and faster gps locks without experiencing the "gps signal lost" error message.

If you are not running the .19 radio along with the latest rcdata.img, download from the above link. If you need further flashing instructions get them here:

This version includes the patch to the build.prop and all files included in Version 3.1 of the lib-ril and gps .so updater for the .19 radio. Once you have updated your radio/rcdata then flash the Wifi Calling Add-On. It is also very important that you flash the Vision EFS wipe after you flash this add-on since you are updating your radio drivers. You should always flash the EFS wipe if you have booted your system with different radio drivers.

IMPORTANT: While you are in recovery, wipe your cache and dalvick cache and wipe the efs partitions by flashing the Vision EFS partition wipe tool.

Feedback and Thanks are always welcome!

Just tried it over Andromadus test 77. First working wifi calling for ICS I've tried. Woohoo!

OP has been updated to Version 1.1

I'm finally able to update to ICS because of this. Thank you so much.

Finally!! thanks!

great work !! thanks alot .. works with my CyanogenMod 9.0.0-RC0 BETA 6[Unofficial]

thanks! wifi calling was holding me back from ics

So far so good. Wifi calling seems to be working pretty well. I was able to hear and be heard, which I was not able to do on previous attempts.

Sorry if this is a silly question-

Im on the $30 walmart/tmobile unlimited data plan and get charged 10 cents a min after my 100 mins are used up. Normally I will be charged if I use wifi calling.

However, I think on rooted phones if you delete a certain file it doesnt count against your minutes used while using wifi calling? Im on Andromadus Audacity Beta 3- will I be able to use this app and not have my minutes count against me?
