When in the 3G mode I can receive sms. My set up is the 3G modem, and when someone calls my cell number, they get a "call failed - user unavailable", so I'm pretty sure your voice mail won't get the chance to notify you.
[Galaxy Tab  Android Development] Infos3c:
Does anyone know what it is exactly that is preventing voice + 3g on t-mobile's network? Are these modem files firmware, drivers, both? Is it a hardware limitation on the t-mobile tab or just not having the right modem file?

Is a hybrid modem firmware being worked on?
[Galaxy Tab  Android Development] xpgroup:
Forward your calls to Google Voice, it'll send you an sms once you miss a call.
[Galaxy Tab  Android Development] rangercaptain:
I will try that idea but forward to Youmail, and get the transcript of the call. Then I can switch if important or sms if that will suffice.
[Galaxy Tab  Android Development] rotohammer:
Its all in the modem file, which is firmware that sets up the capabilities of the hardware on boot up. You can't make a hybrid file as any changes to it will cause a failure to load due to checksum error, and I haven't had time to figure out the checksum algorithm/location yet.
[Galaxy Tab  Android Development] rangercaptain:
Roto and All:

In another forum someone mentioned RIL files as the source of their trouble to connect to a 3G network. Another forum mentioned Lib files. I personally have flashed 10 vibrant and bell i900 modems to try to obtain both voice and 3G data, but I never checked/didn't think about any of the other files that might control the modems. When I was BlackBerry, we combined java files to create hybrid modems and GPS.

Is there anything to my musing, or are we just going to wait for that one lucky release that will solve the problem of voice and 3G from one modem.bin?

http://en.wikipedia.org/wiki/Radio_Interface_Layer

"The Android Open Source Project provides a Radio Interface Layer (RIL) between Android telephony services (android.telephony) and the radio hardware.

It consists of a stack of two components: a RIL Daemon and a Vendor RIL. The RIL Daemon talks to the telephony services and dispatches "solicited commands" to the Vendor RIL. The Vendor RIL is specific to a particular radio implementation, and dispatches "unsolicited commands" up to the RIL Daemon."

All I see is "blah blah blah" and don't understand it, but I know I keep virtual company with coders, hackers, and engineers.

Modem Switch not working properly!!

Roto, sorry to keep being a pain but any other suggestions? as per my previous post i have not installed cf-root.

Has anyone else experienced this problem?
[Galaxy Tab  Android Development] rangercaptain:
Mine won't automatically reboot either. I installed the QuickBoot app and put the widget on the desktop next to the gscript icon.

Question

This only changes the modem, T-mobile is still blocking the device? In other words I cannot simply pull the sim from my G2 and use, will be redirected as before to t-mobile site to setup an account.

I have to say that I am not using the voice features of the Tab, using Hotspot from phone to make connections, but if there was a way to get the Modem to work (full 3G) I would live it even more.

Euro p1000 tab on fido/rogers

Hi All,

I have a rooted P1000 international Galaxy Tab running the stock firmware (2.2) and CWM 3.

Currently on Fido, I am only able to use EDGE and make voice calls. In other words, no 3G.

My question is whether or not there may be a vibrant modem that I can use with ROTO's modem switcher script to be able get 3G/3G+ on Rogers/Fido in Canada on my Tab?

Do you think that one of these Vibrant modem bins could work?

Additionally, which modem bin would I flash back with heimdall to restore my Tab?

Thanks.
[Galaxy Tab  Android Development] PMQA190:
Will this help with intenet not working with voice... I took my sim out of my vibrant and put it in my galaxy tab but I can't open any sites. Everytime i go to the browser to open a site it goes to the tmobile we site.....
[Galaxy Tab  Android Development] rotohammer:
Nope, T-Mobile sucks.
[Galaxy Tab  Android Development] rangercaptain:
Roto, I am about to return my T-mobile tab out of protest. This intentional crippling of the tab is wrong, in my opinion.
[Galaxy Tab  Android Development] mafiaboy01:
The international europe vesion doesn't have NAM 3G, u need to get the Bell, Robbers, or ATT verion.
[Galaxy Tab  Android Development] pt4audi:
My tab rebooted as it should after the switch while i was on JMD, but wouldnt do the same on JME-roto. Anyone else got the same problem?
[Galaxy Tab  Android Development] pt4audi:
Anyone know the APN setting to get 3g service on tmobile after the modem switch. Thanks.
[Galaxy Tab  Android Development] rangercaptain:
I just flashed the vibrant KA7 modem.bin, I have EDGE, and for voice, the phone dials and has good quality, but no 3g signal. FAIL!
[Galaxy Tab  Android Development] rotohammer:
I contemplated that, but chose a different route. I cancelled their service, switched to Simple Mobile at $60/month flat, and use VOIP for all my calls while on 3G.

While here in Hungary, I got a T-Mobile Internet SIM and I still get great 3G and free calls back to the USA via my VOIP.

This is the future, everyone needs to let go of cellular voice and move to VOIP. It will be built into Honeycomb, so embrace the future now!

I use the SipDroid app with Axvoice service.
[Galaxy Tab  Android Development] rangercaptain:
ME

I appreciate the direction to head in. I thought about VOIP the first time you mentioned it, but got no further than tango, fring, and google voice, but didn't like them.
[Galaxy Tab  Android Development] msgfromside3:
Roto , just curious, do u experience any lack with your voip? I am taking sipgate and gvcallback approach since I rarely use phone, but I experience noticable lag in my conversation. Just wondering of your experience. Thx as always.

[Galaxy Tab  Android Development] rangercaptain:
I would like to suggest a new thread in the general questions on the topic of work-around solutions to the t-mobile problem of voice +EGDE or 3g.

There are many clever people here!
[Galaxy Tab  Android Development] rotohammer:
I have a SipGate account and its laggy, but Axvoice is not for me. I chocked it up to SipGate being on the west coast where i'm on the East. But even in Europe, I get very little lag with Axvoice.
[Galaxy Tab  Android Development] msgfromside3:
@roto

That sounds good, especially your experience in Europe. I checked the site and the plan seems reasonable. I will go with that when I decide to pay for voip. Thanks!
[Galaxy Tab  Android Development] raaleck:
OMG, I just installed the new version of the switch modem. When I switched and the tabs reboots it reads nos "No SIM card in device"... I put it on the phone to test it and the phone doesnt recognize it.

What could happened!? Please some help here! It's a Unlocked Tmobile with JME v4 and my phone SIM card!
[Galaxy Tab  Android Development] rangercaptain:
Relax friend, check apn settings, set to auto, then reboot. I got that message about 100 times while I tried many modems. Oh, check that your sim card is in correctly!
[Galaxy Tab  Android Development] raaleck:
Thanks for your response!

I tried it on my cell phone to and the same thing. It doesnt recognized it.

I'm trying to access the APN settings but they are unavailable (In gray color, and don't let me pick them).

Same thing with Mobile AP, Bluetooth settings, and USB Settings!
[Galaxy Tab  Android Development] raaleck:
Ok, I just put my Simple Mobile SIM and it recognized it. So thinking now, when I switched to 3G it fry the SIM.
[Galaxy Tab  Android Development] rangercaptain:
Wow, that's a new one - the sim got fried. But no problem with your tab then? Good.
[Galaxy Tab  Android Development] raaleck:
Yes, I think it fried it. I seeing it now looks like it received some Hot temperature because it's a little deformed in the contact back.

The tab is working just fine. I put other SIM I have from Simple Mobile and recognized it. I tried to make a call and It don't make the call so It was on 3G so I used the switch and effectively turned to 2G and make calls.

So I think I will need to go tomorrow to the Tmobile offices to ask for a new SIM card.
[Galaxy Tab  Android Development] rangercaptain:
Too funny, but thank God not the $600 tab.
[Galaxy Tab  Android Development] adinis78:
There is one way to get voice+edge using a vibrant sim thats how i'm running my tab, but XDA took down the thread due to a rule violation.
[Galaxy Tab  Android Development] adinis78:
Hey thats not true.lol!!!!!!
[Galaxy Tab  Android Development] raaleck:
It's easy but this will need work on the IMEI.
[Galaxy Tab  Android Development] rangercaptain:
You get voice+EDGE by flashing Roto JME any version (v4 is the latest) with the Roto 2G modem. You need to work around the EFS issue to be 3G and not get redirected to T-Mo site.

If you Flash JME and Roto 2G and don't get EDGE, check your network settings, and set to GSM only.
[Galaxy Tab  Android Development] adinis78:
Lol!!!! Didnt want to say how i did it as i didnt want mods to ban me.lol.
[Galaxy Tab  Android Development] raaleck:
Affortunately my Tab is working great. Just get a fried SIM!
[Galaxy Tab  Android Development] adinis78:
Ouch!!! Thats not good.
[Galaxy Tab  Android Development] raaleck:
Not good men, I just tried today the new switch and dunno why when it reboot the tablet don't recognized the SIM I put it on a cell and don't so I put a Simple Mobile one on the Tab and it recognized it.
[Galaxy Tab  Android Development] adinis78:
Maybe a bad Sim....
[Galaxy Tab  Android Development] raaleck:
No, It was the SIM of my cell phone and I was using it, only that I was on a 3G area and I like to test the new switch (I'm not saying the switch process burn it) but something happened when I installed it and test it so when it reboot It was hot and I thinked it doesnt installed correctly. But when I get home I test it on other phones and the same thing. Finally I put the Simple Mobile one and works. I saw the Glory when it got the Simple Mobile one.!
[Galaxy Tab  Android Development] raaleck:
Hi pals, I went to T-mobile today and they gave me a New SIM without paying for it, taked the SIM out of my phone and it's working on the TAB. Wooot Woot!
[Galaxy Tab  Android Development] adinis78:
Nice!!!!!!!
[Galaxy Tab  Android Development] rangercaptain:
And you are getting 3g data? And the modem switcher script lets you change to voice?
[Galaxy Tab  Android Development] raaleck:
Yeah, like the other version of the Switcher. I really doesn't know what happened when it reboot. But Now is working perfect. Receiving 3G and Switching to 2G and Voice!

Thanks for asking!
[Galaxy Tab  Android Development] themaster1978:
Is it working with the voice sim on both the 3g modem and the 2g/voice modem? Without messing with efs?
[Galaxy Tab  Android Development] raaleck:
Efs messing!
[Galaxy Tab  Android Development] themaster1978:
I got excited there for a second...oh well not going to mess with imei. I'll just keep using the wifi router on my phone to provide internet for the tab.
[Galaxy Tab  Android Development] raaleck:
How do you prefer, if you do it rigth you will be ok and you could revert the process trust me I do it. But using the phone as router is a great option since you still have the SIM at the phone and could use both devices. Thats the glory of Android! Woot woot!

I just changed the dpi of the Tab and Im playing with that!
[Galaxy Tab  Android Development] rangercaptain:
Efs messing still necessary! I got excited when I saw that too!
[Galaxy Tab  Android Development] wingtytn:
i dont hav a gscript directory and cant make one im using linda file also hav asto file
[Galaxy Tab  Android Development] raaleck:
Hi Pal, it's created by itself when you install the app Gscript!
[Galaxy Tab  Android Development] rangercaptain:
Did you install GScript?. Are you in the correct directory? 1) are you rooted? 2) did you select R/W so you can write to your sd card?

I used Root Explorer, and at the top of the screen is a button that shows R/O or R/W for read only or read and write, so I can copy, paste, and make sub-directories.
[Galaxy Tab  Android Development] raaleck:
Ohh yeah you r right! The thing here he isn't using root explorer to do this! It was so long I do this that I thinked for a while the app make by default the directory!
[Galaxy Tab  Android Development] wingtytn:
thanks guys for sum reason my device had to reboot twice so wen i swapped sims and it completely rebooted twice it comes up... so far i completed the instructions and now im at another issuse but i dont think we hav a fix for it now my device goes directly to tmous web no clue why but i do recall seeing sumone else having the same issuses a couple days ago the only fix i did see was to trash my imei and rebuild from scratch unless u guys hav a fix im always open for suggestions
[Galaxy Tab  Android Development] raaleck:
The reason is T-mobile is blocking the GT from using cellphones SIMs. They only allow access from SIM they sell to use with the GT by this way the manipulate the costumer to purchase a Data Plan. But why pay for another data plan when you have a data plan. So the way here is making the Tab a phantom so they don't recognize it.
[Galaxy Tab  Android Development] rangercaptain:
You need to mess with the /efs folder but that thread has been eliminated by the moderator.
[Galaxy Tab  Android Development] raaleck:
Correction: only /EFS/ nor /system/efs/

I tried the new vibrant 4g modem.bin (KAF) in my tab - it flashed, but nothing was listed in the phone settings, also I had no bars. I don't think this series shows any promise.

Greetings from Puerto Rico.

For those who changed the kernel modemswitch EXT4 and want to use, it is likely that the tablet does not restart automatically. That does not mean that the application does not work. All you have to do is run the GScript, hope you finish reading and manually restart. Then if you want to return to the other modem and ready to repeat the process. To me is working wonders, ROTOHAMER Thanks, you're a genius.

Saludos desde Puerto Rico.

Para aquellos que cambiaron el kernel a EXT4 y quieren utilizar modemswitch, es probable que la tableta no se reinicie automáticamente. Eso no quiere decir que la aplicación no funciona. Todo lo que tienes que hacer es corres el GScript, esperas que termine de leer y reinicias manualmente. Luego si quieres volver al otro modem repites el proceso y listo. A mí me está funcionando de maravillas, Gracias ROTOHAMER, eres un genio.
[Galaxy Tab  Android Development] rangercaptain:

i just installed the latest JMG on a brand new tmobile tab, i am not getting 3G or H speeds anywhere as everytime i press the switch icon, it says my current modem is YYYYYY and going to 2G/Voice modem, it is not switching to 3G modem...

can anyone who got it working pls help??
[Galaxy Tab  Android Development] msgfromside3:
I have no problem with JMG. it didnt have the working 3g modem for tmo so i ran switcher twice to get 3g which is expected. Do u have roto jmg? You might want to run the switch script from the shell directly.

Btw, i didnt have restarting problem with ext4 either.

Hi folks I just noticed today my GT in call volume is hearing very low and is high. I dont know what could be happening since it heared very loud.

As I know I dont had changed any settings or flashed something.

@rangercaptain... What about yours?
[Galaxy Tab  Android Development] rangercaptain:
There is a service menu setting for volume I used about a month ago. One of the dialer codes, and that fixed my volume issue. Let me try to find you the link.
[Galaxy Tab  Android Development] raaleck:
I just fixed it. I called my self via the GT and Up the volume at the highest level. Then Down two levels and the In Call Volume from the Speaker get fixed. Woot Woot!

I don't know what could be happening. If I Up it to the highest turn lower. But It's fixed by Now... again, Woot Woot!

problem with T849

Please help me deal with my Galaxy Tab T849.

Code purchased on eBay is not suitable for unlocking. Other sellers give the exact same code. Decided to try to unlock the phone with the aid description, but found that the EFS folder in my phone does not contain any files.

Is there any possibility to recover them?

Thank you for your reply.
[Galaxy Tab  Android Development] raaleck:
Unafortunately if you don't had a backup of the EFS or the image of your tab you don't will be able to recover it.

What you mean with unlocking?

Copy /sdcard/modemswitch/switch.sh to the /sdcard/gscript/ directory.

Please tell me how to perform the above step? I have installed gscript busybox. Do i need to copy paste from root explorer. I don't see GSCRPIT folder in sd card when mounted to PC where i can copy paste switch.sh.

Thanks.
[Galaxy Tab  Android Development] rangercaptain:
If you installed Gscript the directory was created. But I used the root explorer to create the directory, and used it again to copy paste.
[Galaxy Tab  Android Development] tabing:
rangercaptain i am in root explorer and looked for it everywhere but gscript is not there. I just installed from the market the light version. Baseband JHA, roto-jmi

please help, thanks.
[Galaxy Tab  Android Development] raaleck:
Hi Pal, you need to create the directory by yourself using rootexplorer. You need to create it on /sdcard/gscript/

Hi Rotohammer,

I have done your steps of modemswitch done succesfully with your and other members help. But i still see EDGE icon near bars though the inetrnet speed is improved. How do i know the process went succesfully.

Other question is tab cannot receive calls while surfing web through EDGE. With wifi i can surf and receive calls with no problem.

Tmo Tab, att sim, baseband JL3 roto-2g

build number roto-JMI-v2

Any solutions please?

Thanks
[Galaxy Tab  Android Development] raaleck:
I know this question was for roto, but I will tell you about my experience.

1rst. You can check at SETTINGS/DEVICE INFORMATION/BASEBAND here will tell you if it is on 2G or 3G.

The tab receive calls on Edge, the thing is if you receive a call it will get disconnected until you end the call.

If you surf via Wifi you will receive the call to and could still surfing with the call on background.

Again, I hope this answer your questions.
[Galaxy Tab  Android Development] tabing:
Raaleck thanks so much you really clarified things. My experience is also like yours web surfing on edge but calls and.........

+3 tomorrow used all 5 today
[Galaxy Tab  Android Development] rotohammer:
Thanks raaleck! This is what I expect to see from more members. If you know the answer please post it, especially if the question was directed to me. I'm so busy now with work that I can't get to every thread I've started to answer questions.

gscript does not install a directory into my SD card help please!

THx
[Galaxy Tab  Android Development] rangercaptain:
Just use root explorer to make the Gscript folder. Then copy the file into it.
[Galaxy Tab  Android Development] raaleck:
As rangercaptain say, you need to use Root Explorer to creat the Gscript directory.

Using Root Explorer touch menu and you will see a menu comes up, touch New Folder, remember you need to Mount the Tab on R/W.... this option is on the top of the display... this is in order to can write on...

So again... go to Menu, New Folder... and name it "gscript" <---- with out the quotes!

I hope this help you!
[Galaxy Tab  Android Development] newbytech:
gscript doesnt read the gscript folder its x:/sdcard/gscript is not being read by the program
[Galaxy Tab  Android Development] raaleck:
Hi, if you created it its supposed to be there, remember to paste the .sh file into it and then go to gscript to read it.

If still dont work try to repeat the instructions from the beginning! Hope you fix this.
[Galaxy Tab  Android Development] Bugman1:
1. Download root explorer from the market.

2. Use root explorer to create the folder /gscript as a subfolder in /sdcard. Folder path should read "sdcard/gscript" without the quotes.

3. copy the switch.sh file to the sdcard/gscript folder.

4. follow the rest of the instructions in Roto's original post.

you're good to go.
[Galaxy Tab  Android Development] jay_jay_n:
Can you post up the service code because I'm having issues with low speaker volume on in calls and adjusting the volume like you stated isn't working =/
[Galaxy Tab  Android Development] Dkmack:
I have a question so according to base band Im on 3g right now but getting 2g speeds anyone may be able to fill me in as to the problem.

modem switcher to 2g and phone works fine but its the 3g side when switching I would just think the speed would be better i.e. its the same speed for 2g and 3g for me.

Ideas welcome -
[Galaxy Tab  Android Development] rangercaptain:
Check your settings>wireless and network>mobile networks>network mode and set to auto. It sounds like it is set to gsm only, which would keep you at 2G.

If not that, select your network operator again by making that automatic.

If not that dial *#1234# to verify the modems are different when the switch script is run.
[Galaxy Tab  Android Development] Dkmack:
thanks for the info I chk'd it all out and everything is as it should be when changing modems back and forth. I then went to tmo site logged in and saw galaxy tab under my phone using the sim from my hd2.

Went and restored imei to original powered up and down then did the efs manouver and it is now working again, is it possible that the tmo system is having issues and not sure to put the tab back on 3g because after a time it will not go back to 3g and only stays on 2g even though tab info in all places shows as 3g modem in place.
[Galaxy Tab  Android Development] raaleck:
Pal sorry for the delay, I just don't received the notificacion of this post. I hope I still can help you.
