CM12 for XT1028 (Verizon) and XT1031 (Boost Mobile)
aka, the devices forgotten about by Motorola and CyanogenMod

UPDATE: 04-02-2015

With the goal of this thread having been solely to get 3g data working, it is "mission accomplished"!

There will no longer be a build posted here...please use individual build threads to download and discuss.

Thanks to everyone who helped bring working calls and data to the CDMA Moto G!

This is the workaround that @crouse came up with.

The original boolean values were changed so that we no longer need a SIM for the phone to initiate a call.

location:

/home/dev/android/system1/packages/services/Telephony/src/com/android/servic
es/telephony/TelecomAccountRegistry.java


Code:

*** // If we did not list ANY accounts, we need to provide a "default" SIM
account

******* // for emergency numbers since no actual SIM is needed for dialing
emergency

******* // numbers but a phone account is.

******* if (mAccounts.isEmpty()) {

*********** mAccounts.add(new AccountEntry(PhoneFactory.getDefaultPhone(),
false /* emergency */,

******************* false /* isDummy */));

******* }



******* // Add a fake account entry.

******* if (DBG && phones.length > 0 &&
"TRUE".equals(System.getProperty("cdma_sim"))) {

*********** mAccounts.add(new AccountEntry(phones[0], false /* emergency */,
false /* isDummy */));

******* }

oh good you found it, after that i got smarter and just made the subscription manager check if the phoneid and subid were >= -1 which did the same thing. everything does seem to actually work, but for whatever reason the code isnt finished / is missing what makes a cdma only phone ok. with a sim everything checks if the id's are >= 0 when with a cdma only its set to -1 .. idk if it makes any sense but thats what got it going

And in TelecomAccountRegistry.java in the setup accounts function check if the subscription id is >= -1 i instead of zero

I noticed in looking through old logs that ConnectivityService seems to look for phoneid of -1000 when trying to bring up the network. Wonder why that is... shouldn't it be the same globally?

Need to pull some recent radio logs...

yeah, -1000 is invalid for phone id and some other things changing that makes the phone break completely

If this works, then there may be hope for the Moto G CDMA Community.

I can confirm calls and SMS working on xt1031. I'll try to get some logs soon if that will help.

Radio log pulled with extreme logcat since I'm not near a PC.

Also, it may be helpful when taking logs to make sure WiFi is OFF so that the 3g network is attempting to connect. Then toggle airplane mode on, wait 10 seconds, and toggle airplane mode off and let it try again to connect. This may help expose more for us to examine.

I apologize, but how is someone able to send SMS if 3g data don't work or are you guys sending it threw WiFi?

Great, thanks.

Right after RIL bringup we get SIM_COUNT=1

And then we end up with a bunch of failed inits and nulls because of incorrect subID.

I think we need a convenient way to "crowdsource" searching through source. Anyone able to upload raw telephony/ connectivity folder trees somewhere that everyone can participate in looking for relevant code?

SMS works over voice network, not over data network

I don't know anything about how this all works. But the "unexpected number of modems 0" line seems odd. Also, there's a lot of references to CDMA in the logs so it's somewhat detecting a CDMA device, maybe?

Yes, but it also thinks that this CDMA device is an LTE device... Because of the SIM issue.

The unexpected number of modems also reflects that it is requiring a SIM to establish a network socket.

if we can tell it not to look for or require SIM in the first place, these errors will resolve and we should end up with a connection

Alternately, we may be able to trick the system into thinking there is a SIM and then directing it to use NV manually... Probably a more likely fix right now.

 

[mightysween]

Notes, mostly to help keep track of what I have looked at:

Looking around here...this is where we need to be able to provide correct subid and introduce the possibility of there being no SIM at all. As noted earlier "sim count" is being returned as "1".

https://github.com/CyanogenMod/andr...nmod/setupwizard/setup/ChooseDataSimPage.java

So, before the Setup Wizard gets this far, we need to have established correct subscription and set simcount to 0 (even if it needs to be done manually for purposes of testing). Then call new function that takes proper info to establish data connection


This is probably where it will take place:

https://github.com/CyanogenMod/andr...ogenmod/setupwizard/setup/MobileDataPage.java


This shows that the only option right now for data is to either have one or two SIM cards, and if absent to route to a missing Sim page. Need to now look closely at Telephony Manager where SIM count is actually established.

https://github.com/CyanogenMod/andr...nmod/setupwizard/setup/CMSetupWizardData.java

subid relies directly on SIM and will not be set if SIM is unavailable:

https://github.com/CyanogenMod/andr...id/internal/telephony/SubscriptionHelper.java

Sim count coming back as one might be because of the changes I made, try an unmodified one and see what it comes back as

Right, and that is OK as long as we can use the same dummy "Sim" to establish data.

 

[crouse]

One thing I keep thinking would help is if someone with the first gen 4g version ( single sim ) posts their logs , with sim, without sim and with sim starting up and then removed. Someone posted at one point that if they started up with the sim in and then removed it everything worked fine with just the 3g CDMA radio but if started up without it they had the same issues we do.

Looking back at that thread, it seems that we never confirmed whether his phone was actually registering as CDMA and not LTE.

Mine correctly sets the radio technology as CDMA, but CellInfo shows that it is registered on the network as LTE, but without MCC...sorta like a 4g device with no SIM. This may be the root of why data fails, or just a symptom of the problem.

Since we can confirm that the network is in a ready state, perhaps preventing LTE registration may be a solution, but I am not sure there is a way to do that as long as the device thinks there is a SIM.
