[HOW-TO] Enabled GSM Phone calls on the JTC Jetstream (S-OFF - ROOT - WIP)

Yes unlock bootloader not equal to S-OFF. BTW can somebody help me with stock ATT rom for Jetstream?? Somebody can nandroid backup his device or something. I need to reflash my ATT device to factory but I cant with footballs uploaded zip. I cannot use my device now. I have a topic started with this in the development section. Please help. Thanks

Back on topic...
I followed all these steps and I am not seeing the dialer app appear after reboot.

Am I missing something?

were the changes to the build.prop saved? cause sometimes if you don't mount the internal memory, the files are view only the changes arn't saved.

make sure that you use a file explorer that allows you to mount the internal memory. and make sure you remember to mount it.

Thank you, making sure I saved the changes was a big help.

It is sudo working now. I just get no sound either from speaker or BT.

I will have to dig around a bit more.

Now, I wonder how long it'll be before AT&T starts sending out nastygrams about using this device as a phone in much same way they did back with the original Galaxy Tab... "You're using this equipment on our network in ways we didn't intend for it to be used! C&D!!"

Granted, only people with grandfathered unlimited plans, or people with tiered data, but no tethering add-on will likely see these nastygrams... Mark my words though, it's just a matter of time...

Greedy money grubbing bastards AT&T... *mumble grumble*

Wow, is it just me, or did my post really bring this thread to a grinding halt? o.o;;

Indeed the magic works - Confirmed !

Unlocked the Bootloader via HTCDev.
Rooted the Jetstream
Modified the file
Installed GO SMS Pro

What is working:
-----------------
- Using ORANGE SIM card
- Got the Phone icon
- Able to dial to any mobile number (but no Voice on both sides)
- Able to SEND & Receive SMS
- Able to get missed calls Notification

What does not work:
------------------------
- No voice during call session - other side is connected but no voice at all
tried speaker, tried HTC headset, nothing works - No voice.

- No ringtone or RING Notification when other side is calling the JetStream,
Only missed called notification after hang up

Anyone got better that i did ?
Any suggestion how to get voice working?

At least SMS is working Perfect - both sending SMS from the JetStream or Receiving SMS to the JetStream (using GO SMS Pro) , also SMS notification works.

No Sound for phone call

B"H

Same by me - No sound.

Unit makes calls, but I cannot hear no matter what.

Interestingly, even though my headset is "paired", the device still states Jawbone not paired.

And the phone app is weird - it always changes to portrait mode, and doesn't have all the normal options on it.

Any help?

Thank you,

Any news here with the Voice issue ?

Has anyone did managed to get voice either with HTC headset or with a BT headset ?

After enabling GSM calls, is it possible to forward calls? Would be great if that were possible..

Can't get S-OFF on mine. I have tried more quite few times but nothing. I only get root but not S-OFF. I know S-OFF is not so important for now since there's not too many roms to choose from but it would be nice to be on the must-update-device-to-install-roms list

About missing voice, test HTCacoustic libs, if there.is a sound image.folder check.the.files, the codec and.CVS files on.etc folder, reg files, all about Mic sound, stock HTC mms.apk needs some editing I will try look into it, but no promise as for sound you guys have.to mess.with on your own, as one need the.tablet to figure it out hope it.points you in the right way sorry for all the dots, hate typing on phone

I came across some threads on the Flyer section where after updating to Honeycomb, they are not able to make voice calls-rather they can make calls but the no voice problem etc remains. So here is just a wild hinch that our problem may be due to the honeycomb OS itself rather than the process of enabling calls. Maybe someone with more know how can check into and/or port the voice call necessary files from the gingerbread flyer for us..or we would have to wait for the much coveted but yet unconfirmed release of Ice Cream Sandwich for our dear Jetstream..

Hi, I finally used the enable gsm calls method and was successful. While playing around with it, I discovered something which may be of some use.

Call forwarding as I had asked is possible and very much works. I live in India and own an Airtel SIM. So searched for any MMI codes which would help me enable it. Found some and tried them. So, to forward all calls:
To start, enter **21*number #
To stop, enter ##21#

Note-I do not however know if it is the same codes for other networks. Have tried it on Aircel, Idea and they work perfectly fine with both. Probably if this does not work with other networks, could just google for the codes for individual networks.

Once you do this, you will notice a small blue call forward icon at the right bottom of the screen. On opening this, you will see Call Settings. Screen shot attached. There are options for Voicemail Service, Voicemail settings, other Settings like-TTY Mode, Hearing aids, Phone settings, Cell broadcast, Cell broadcast settings, Call forwarding, Call Barring settings, Additional Settings, Home Country and Home dialing.

under the Additional Settings, is a tab for Caller ID and Call Waiting. Phone settings has Edit Default Message, Edit message and Save to contacts.

I have not got the sound to work as of yet by playing around with any of these settings yet though. I have not been able to figure out which service or process is it which gives us these settings. But may be some developers may be able to figure something out. Who knows, we may stumble upon the actual process which may give us sound in calls and more access to the system resources.

P.S.: Kindly note that in order to cancel the call forwarding, you must use the MMI code itself - i.e. ##21# or else it will continue to forward calls even if the sim is on a different handset.

so calls work .again no sound and messaging as well.

now i was able to get my hands on a deoxed version of mms.apk (version 3.0.2) and place it in the /system/app directory and changed permissions.. it launches i send a msg , it doesnt send, timesout of retrys, then it FC, so im close lmao i got it to work with GO SMS PRO, but would prefer the sense messaging version..

one thing i found weird was the face that the options when holding down on a msg is all messed up under the stock mms.apk and when typing in a contact to send it to. the dropdown list of contacts.doesnt find anyone..hmmm

any ideas..we going in the right direction?

I already had a hint in how to fix the problem..
The problem is that I don't have the proper Linux setup.
Im actually waiting for a developer to make a de-odexed rom,
If a (good) custom rom gets released I will have another swing at it!

Hi,
Any luck with the solution to fixing the problem? Some roms have emerged including by Task650. may be you could share what the problem might be related to and others on the community can try fixing it as well.

Ok. I did play around a bit and try different things. Here is what I managed to do and get to.

1. /system/etc/soundimage - srsfx_trumedia_voice.cfg shows configuration for a lot of sound realted issues - like routing-output device, BT headset, speaker, wired headset, AUX/line out with each having blocks like hard limiter, TruEQ, CSHP and WOWHD. These settings include gain - found some set at 0.400 and others at 1.000. So I did play around a bit with the gain settings and did manage (I think) to improve the sound reception on google talk - not sure though if it actually happened or if it was just because i thought i had changed something. The souting-output device section has a lot of disallowed devices including Bluetooth A2DP - did try enabling the wired headset and seeing if anything happens but in vain - I think some of the other settings specific for the BT headset must also be altered.

2. /system/etc - some files like A1026_CFG.csv, AdieHWCodec.csv, AdieHWCodec_WA.csv, AIC3254_REG.csv, AIC3254_REG_DualMic.csv
Each of these files has some binaries set for stuff like phonecall_reciever, phonecall_headset, phonecall_speaker, phonecall_by.vr_no_ns_reciever. I could not figure any of this out so have not touched any of this.

3. /system/etc - CodecDSPID.txt and CodecDSPID_PVT.txt - both seem to have definitions for various sound+mic functions - for phone, playback, recording, voip. All except phone have values set with definitions for certain files within /system/etc/soundimage. Phone is left blank. As all of them seem to be specific for each function, I do not know what to define for the phone functions.

4. /system/etc - IOTable.txt and IOTable_XB.txt - both as I understand have binaries set for input-output with each method of input having binaries specific for it. Again as I do not understand, have not touched these.

5. /etc/permissions - tablet_core_hardware.xml - the permissions include instructions which say that GSM phones must also include android.hardware.telephony.gsm.xml which is missing from the folder. May be if we could get that file, try incorporating it and testing what happens.

These are what I found. I am not so well versed with binaries and stuff so I do not know what to do further. If anyone else who has the know how is interested can can try taking this further, will be much appreciated.

Edit: In case this is all basic stuff which has already been checked by more experienced users than me, I am sorry about repeating known stuff.
