I have a Model SGH-T849 Galaxy Tab, Firmware V 2.2 from T-mobile
I've been reading that a European version of firmware will allow some tabs to be used to make phone call. ([How To] Flashing Euro Firmware on Samsung Galaxy Tab Video Included) I found this thread...
Will this work on my tab?
I would like to know before I start and brick it.
I've been reading and reading, but have not found a defitive answer.
Thanks in advance for any info or ideas.
Any rom besides a stock t-mobile rom will enable voice, with a compatible modem. Don't mess with that thread on installing a euro rom - that's so last year.
Flash the stock-safe JQ1 rom, flash the CF-Root v3.3 kernel to root the tab, then install the Rotohammer modem switch.
With this set-up, which is what I have on my t-mobile tab, you will have to switch between two modes: 1) voice+EDGE data and 2) 3g data only, but you can't have both.
Rangercaptain, You've been very helpful...

I presently only use the tab for wifi. Its more of a toy. I used you post for using it in airplane mode and turning off data. It works great, thanks.
I don't need edge or 3g, I really don't even know what they are. Only tmobile voice and wifi.
I have not rooted the tab because i have been unable to figure out how...I know there are two ways, oneclick and x4root, but am afraid to screw up my tab.
I need a step by step instruction to get it all done. Any help will be appreciated.
Thanks for all you help and support so far.
Search for the t-mobile wifi calling app.

rangercaptain,
I downloaded: CF-Root-TAB7_XX_OXA_JQ1-v3.3-CWM3RFS and Odin3 v1.7. From this thread: [11.05.2011][CF-Root v3.3] JJ*, JM*, KA*, JQ1 - su+busybox+CWM3/RFS
Am unable to find Rotohammer modem switch.
Am I going in the right direction?
I use the Odin3 to link the tab to my computer and then flash JQ1. I then flash Rotohammer when I find it.
Thanks.
You have everything ready, except the roto hammer modem switch files.
1) flash the JQ1 rom to get gingerbread. There are two ways to do this, one from chainfire, or one from team overcome (they call it stocksafe v5).
2) flash the CF-Root v3.3kernel to get the root permission.
3) add the folders, files, and app to make the modem switch.
At this point you will have stock, rooted gingerbread on a t-mobile tab that can make voice calls.
You will have to do one final procedure to use a sim from another t-mobile smartphone and get the 3g data working:
1) Back up the /system/efs folder to your pc.
2) delete the files in the /efs folder on the tab.
The t-mobile wifi calling app isn't as good as skype, and can't do video calls.
Help, what have I done???

I found this thread: [stock rom][2.3.3] p1000xxjq1 p1000xxjq1 p1000xxjpz
Followed the instructions to the "T" and can now make calls using my T-mobile sim card in my TAB. I'm still not sure what I did, but it works.
Thanks to Rangercaptain and the others on the XDA site.
You can't image how happy I am...It made my day.
Now flash the CF-Root file. You will need root when you come back asking about 3g.
Howd you get so smart???

Hi All,
I bought the Bell version of the phone (Vibrant) because I wanted the front facing camera... Then unlocked and rooted it and inserted my Rogers SIM and have had no issues for quite a while. I successfully loaded Froyo when it became available on Kies without any sd problems. (had to re-root but no big deal).
Now I understand that Bell has released Gingerbread via Kies, but when I open Kies, it doesn't recognize my firmware at all... just shows blank.
I un-rooted and erased all data to see if that would allow me the upgrade but still nothing...
Can anyone offer any assistance or have the files that I can install using a different method?
Much appreciated,
Jamie
Use the search Luke....
Seriously, there is a huge thread detailing Bell's KG3, including dumps you can flash with Odin instead of using Kies. The best part? Even though it is only 9 posts down from yours, I ever got you the link http://forum.xda-developers.com/showthread.php?t=1211939
If you don't want to use KG3, just flash any of the Gingerbread roms in the development forum and flash an appropriate modem. 99% of those threads include flashing instructions.

Thanks,
I did read most of that thread but can't find anyone else who's using a Rogers SIM on an i9000m... I don't like or use Kies very often and I'm getting annoyed that it won't seem to even read my current firmware. MyPhoneExplorer seems to read it just fine but Kies seems to only want to be some kind of media toy.
I will borrow a Bell SIM to see if it will recognize long enough to use the Kies update, and if that fails I'll flash with Odin.
I assume I'll have to root again once I flash?

Yes you will.
make sure you have the latest version of kies, also make sure your csc is set to BMC (open dialer *#272*"your imei"*), select BMC and isntall that will factory reset your phone btw... after that it should work... I am not sure that a Rogers Sim card is affecting it, have you tried just pulling the SIM altogether and connecting? Are you running any custom ROMs currently or have you in the past? Maybe flash back to UGKC1 with Odin if you are and then use Kies to update.
Ended up finding some detailed instructions on "MostlyIrrelevant" for installing 2.3.4 with a Rogers (and Bell) supported Modem. a couple more steps to install the ROM, but it's a deodexed version of the international release with the bloatware removed and TW Launcher removed and replaced by TouchWiz... nicely also has CWM and Titanium in it too, so flashes are much easier from now on. (small workaround to get Bluetooth working but the solution was also in the comments section.) Next step to get back a couple pieces of Samsung bloatware back on... mostly SocialHub and Samsung e-mail... so I can connect all my contact lists and e-mail accounts into one place. I bookmarked the link to Pharaohnough's posting of the apks for these apps (THANKS!) that I want back but will have to wait 'till after work to try them.
hi all
i picked up a used rogers galaxy tab 7".upgraded to 2.3.3 official via kies.
GT-P1000R
rooted it.
unlocked it.
now i wish to use the phone capabilities and have a few questions.
i see in a couple posts that you no longer have to flash a complete rom,just a modem.
is that info correct?
i see that the jm2 modem seems to work best with the rogers tab,so do i just flash the modem with odin and that gives me the voice capability.
or do i need to flash a complete rom(European)?
also there is no dialer program so where do i get that at?or does it come with the modem flash.
is there a better modem than jm2 for the rogers tab?or the bell i9000 modem?
i am in canada
thanks,jeff

Careful what you flash though, if it's from XDA any ROM should do you okay but Samsung official ROMs may contain locked boot loaders. Catch up on some reading before doing anything.
Also i suggest that you do a complete backup of your tab before flashing anything else so that you could revert back in case of issues. Stock ROGERS firmware is hard to find. And if you do a backup I wouldn't mind a copy of it as long as you keep your personal information out. As a matter of fact, what i am after is a un-rooted fully stock ROGERS ROM. As i have deleted my original backup, and would like to revert completely back to stock, I would be very thankfull if you could help. But none the less you should do a complete backup, something like the roto or nandroid backups.
Try the OVERCOME rom, it's a great place to start as a noob to flashing, they have very detailed tutorials and the ROM is good.
EDIT: And the OVERCOME rom does work with the bell i9000 modem just fine for phone calls. Although the volume on the tab is not the greatest for a speakerphone.

darned,i rooted and unlocked it earlier this week.
i definitely would have done a stock backup for you.
can i unroot?i used oden and one of the cf rooting images.
unlocked using galaxy s unlock from market.
can i even revert back to stock?if so i will do a backup.
i have done nothing else to the stock rogers 2.3.3
i searched my hardrive but kies must delete the firmware after flashing.

Thanks for the offer. But no need to go through all of that unless you can un root with something like super one click (fast and easy, but I don't think that will work for you). If your tab is still under warranty you might want to learn how to root and unroot and restock and such (its all covered in the forums). Otherwise I don't want you playing with your tab and have a "bad" flash trying to help me out. Do read up in the dev section before you start flashing custom ROMs.
That said if you do feel comfortable flashing and decide to make a backup for yourself I definitely wouldn't mind a copy.

hi
not scared of bricking the tab,i have been flashing samsungs for the last couple years,captivates etc.my last tab i did a supposed gps fix which ended in a bootloop.
i managed to get it back but with a modified 2.2 firmware.then kies would not let me upgrade to 2.3.3(unofficial firmware error)
my problems have always been actually returning to stock.
in recovery i have the orange clockwork recovery that has an option to do factory reset.will this take me back to unrooted and unlocked???
if so consider it done.
i will need direction to do a full backup after that.
jeff
Doing a hard reset will NOT un-root or re-lock your device (as far as I know). The factory reset will clear the data and cache and should not touch the system. You have to un-root your device using the method you rooted it with or something along those lines.
As far as a backup is concerned, creating a system backup has been covered in the forums before. There is plenty of detailed instructions on performing a backuphave a look at the Roto Backup method.
Just picked up a galaxy tab ( rogers )
gt-p1000r
firmware 2.2
all stock
no root
no unlock
I would like to "give back" something
for all the HELLp you guys have given via these forums
( i swear all my grey hair started once i dumped my blackberry and went samsung and found this site! )
Anyway
If you are still looking for the a copy of the STOCK system before I start to play...
I will try to figure out how to make a copy for you
I have T-Mobile Galaxy Tab 7.
After using Overcome for a day, I think I prefer Froyo. Could anyone guide me as to how I can go back to Froyo 2.2? Also, in the process of upgrading to Overcome, I upgrade the tab to 2.3.6 gingerbread. Is it possible to just uninstall the Overcome and use gingerbread? Please guide me thanks.
yes, just follow overcome guide again to restock.
That is by using Odin to install the GB-Stock-Safe from overcome site.
With that you will get GB samsung stock, without anything overcome at all.
You will get the dialer, so in theory you can make phone call with the right modem.
Unless you really prefer Froyo stock from T-mobile that doesn't have dialer, you can get download the firmware and flash it. (if you can find your firmware version)

So all I need to do is install GB-STock-Safe with odin and I'm back to gingerbread? If that's the case, I would like that, I like gingerbread. Also, after I installed overcome, I did get the dialer but when I installed my AT&T sim card, it wouldn't detect it at all. I then used Galaxy S unlock tool from the market to unlock. I was able to unlock it and then the Tab was able to recognize the AT&T sim but when I dialed a number, it would automatically hang up. How do I fix that? Is there something I need to install to get the phone working? thanks a lot!
have flashed a different modem before?
T-mobile has a different frequency. You may be able to flash AT&T modem or other modem via CWM recovery.
There is a modem thread in the dev section.

Could you give me the exact directions please? I'm new to this. thanks
you have managed to flash overcome 4.1, you can't be that new.
First go to your setting, About, and note down your phone Baseband
that is actually your modem version.
Now, if you restock back to GB Safe stock, you will not be able to do what I said below, because this is based on CWM recovery, which is included in Overcome Kernel.
The good thing is, once the right modem gives you all the functions (call, sms, data) you can then restock to GB stock safe and the modem won't change.
Go to http://forum.xda-developers.com/showthread.php?t=1069727
and download a few of the modems. Maybe a JPZ, a KM2, an AT&T modem, and T-Mobile modem.
Put them in your sdcard like when you flash overcome rom.
reboot to recovery
choose to install from sd card
locate the modem zip file and install it.
reboot and try out your data, sms, and phone calls.
If no good, reboot again to recovery and try different modem.
It is a hit and miss for some people.
If you already restocked and has no CWM recovery, you can still use Odin to flash just the modem.
wow it's working! i downloaded JPZ modem and did installed from internal sd and now i can finally make phone calls!!1 thank you so much! btw, can I now go back to stock froyo or gingerbread and still keep the voice? also, if I were to just use odin to flash the modem on a stock foryo galaxy tab, i should be able to make phone calls right? again thank you so much!!!
yes, that is right. The modem should stick, if you downgrade to GB stock safe.
Having said that, if you downgrade to Froyo and the package contains a modem.bin, then it will get overwritten. Then you need Odin to flash the modem again.
What network are you in? As long as you are not in T-Mobile network, you should be fine. I myself own a T-Mobile galaxy tab, using JPZ modem in Australian Optus network. I can make calls and have 3G/HSDPA data connection.
I'm using it on AT&T... i don't have a data plan, but if I were to get a data plan, would it work with the JPZ model or do i need to use anothe rmodel? thank.s
Hard for me to say. I don't know much about AT&T
It seems like HSDPA in AT&T is 1900 MHz
I am pretty sure most networks are on 2100 MHz (Europe, Australia, Asia)
Can you get a data plan SIM and try it out, and try the AT&T modem in the modem thread as well?

weird,
this external link
http://www.talkandroid.com/21900-sa...ers-bell-hacked-for-voice-calls/#.TzDI56fnitI

Hey, I was trying to install ICS after downgrading back to gingerbread from overcome.
So, after get the CM9 and gapps from humberos website, I put them along with the overcome kernel in the root of internal sd and reboot in recovery however, after flashing the CM9 zip, I cannot see the overcome kernel anywhere. So i proceed without flashing that and after rebooting i get stuck at galaxy tab logo. can you help? thanks
You wasted quite a lot of effort.
You should go straight to ics from overcome.
try flash overcome kernel using odin (the tar version of the kernel)
Then boot to cwm and flash cm9 rom again followed by humberos cm9 kernel for P1000.
But if you have patience, wait a day or two. Humberos will have newer rom+kernel that fixed slow wifi and quite a bit.
Meanwhile you can flash stock safe again while waiting.

Greetings,
Just picked up a T849 7" Tmobile Tab for wife.
It has the stock 2.2 and unable to make phone calls etc.. (shes on simplemobile)
Anyone in S.FL that can root/rom /update this little tab? cost?
THX
shoot me an email: bluzboy125 AT h o t m a i l <dot> c. o. m.
Go to overcome site
http://www.teamovercome.net/
Read the guide,
Missing pictures can be seen here.
http://forum.xda-developers.com/showthread.php?p=20974872
just follow and you will end up with Overcome 4.1 Gingerbread ROM which is very close to stock samsung.
Or you can stop right after you flash GB-stock-safe-v5.
Basically to restock:
Download GB-stock-safe-v5.zip, unzip it and and flash with ODIN according to the guide.
Then flash overcome kernel.
Then flash overcome ROM
But please make sure you get good download. Many people have to download a few times to get it right.
Use a tool for checking sha1sum to compare.
For example:
http://download.cnet.com/MD5-SHA-1-Checksum-Utility/3000-2092_4-10911445.html
Thanks for the info. I downloaded most of the files.
Do I still need to do the SGT Bootloader Patch? (I have 2.2- tmobile now on the t849)
I actually did download the bootloader patch, but cannot find the APK file in the download.
I may stop at the GB stock V5 update, but if all goes well, may continue to do the overcome ROM further down in the instructions.
No need boot loader patch.
straight away using Odin to flash the GB-stock-safe.
I forgot to mention to you, since you are on T-mobile.
To make phone call, after you get a ROM that support it, AND you need to flash a different modem.
Read this:
http://forum.xda-developers.com/showthread.php?t=871021
Basically if you want 3G you can't make call (calls will end).
So you need a modem that allow voice call, but you only get 2G.
