[GUIDE] US Tmobile Galaxy Tab flashed to make phone calls

As mentioned in;
http://xdaforums.com/showthread.php?t=837266
in case it got lost at the end, we now have the US TMobile Galaxy Tab making/receiving phone calls.

Download Odin3 v1.70
to flash.


Used;
P1_20100909.pit
for formating. Selected 'Repartition' 'AutoReboot' 'fResetTime'. That rebooted with nothing apparently working but the filesystem structure was setup.

Download P1000XXJHA
for the base rom.


Then, unchecked the 'repartion' part (as the structure is setup, don't want to screw it up, the next flashing needs to 'drop in' where the structure is.

Then, loading into the JHA.rar just downloaded, flash that and reboot.

To update to latest;
download and flash;
P1000OXAJK1.tar

Pop in your SIM.

At this point, reboot. It'll probably show 'Emergency Calls only'
Went into the wireless/Mobile Settings/NetworkOperators and made sure it was connected to TMobile.
At that point, I made my first call and it worked.
Received a call too, also working.


Good luck. If there's an easier way todo this, I'm all ears as I had a few moments of 'uh oh, why's it now showing anything' but the fantastic forum posts here with people having the same problem resolved that.
Only working on Edge at this time also.

No idea how later updates will work too, so caveat emptor.


*Edit. Further adventures.
So, now having the euro stuff on to make calls, but having the issues, wanted to try a few things. Put the US Tmobile back on to get 3g but lose voice.
Firing up a call, logs showing;

Interesting the error message shows it's APN. Leads me to (wildly) guess that a new radio COULD be worked out, but also the carriers could send out an update message to allow it to work without other upgrades. If so, then there may be an 'enable switch' we can use to get it working too.

I went to *#2263# menu and selected all the bands, including 850 and 1900, but still nada. Most of the time my tab losses total signal and goes into emergency only mode. I have played with the setting but no luck so far with ATT. Anything I am missing?

Now it looks like it is connected to ATT but I have zero bars and is showing a "G" for data. I know I have full strength signal here. =(

I can confirm I have the exact same behavior with my Tab on AT&T. Perhaps is the radio from the Euro firmware? Considering I also lost 3g on T-mobile as well, I would hope its just a crappy radio instead of an intentional crippling by Samsung.

Making phone calls possible

Here is a another story about making T-Mobile Galaxy Tab that eventually can save somebody some time.

1. What is needed:
- T-Mobile Galaxy Tab with USB debug enabled
- Windows PC with two Samsung applications available:
Kies_1.5.3.10103_100_2.exe - for installation of download drivers and nothing else
Odin3_v1.7.zip - flashing utility
- P1000XWJJ4.rar - European ROM package that contains 4 files
P1_add_hidden.pit - "PIT" files defining memory stricture
P1000XWJJ4-REV03-ALL-CL639474.tar.md5 - "PDA" core firmware
MODEM_P1000XXJID.tar.md5 - "MODEM" firmware
GT-P1000-CSC-SERJJ2.tar.md5 - "CSC" firmware

Rar file should be unpacked into the same folder as Odin.

2. Flashing procedure:
- shutdown the Tab
- replace original SIM card with another one that has a phone number
- launch Odin..exe
- put the Tab in the Download mode by pushing simultaneously buttons "Volume Down" and "Power". In result you should see a yellow digger in triangular on the screen
- connect the Tab by USB data cable to PC
- Odin should show active (yellow) ID:COM window with COM number
- select options Re-partition+Auto Reboot+F.Resre Time
- select corresponding files clicking buttons: PIT, PDA, PHONE, CSC.
- click start and hope for better

It takes about 10 min to finish.
Surprisingly, my Tab booted in Russian locale. All European languages are available and you can change to whatever you wish.
My regular T-mobile SIM card worked without questions. I could place calls without any extra efforts.
It is amazing!!!
I've got ROM and Odin using links in XDA, Kies - from Samsung support portal.
Be careful to do flashing for the first time. You should have all firmware files when selecting re-partitioning. Later you can update just one particular component without it.
I did not study ROM differences but you can learn it from samfirmware.com

Enjoy!!!

After my attempt to do network unlock screwing the nv_data I've lost my original serial number as well as imei. This is a big deal because it is identification number of the phone that should be protected to avoid identity theft.
Luckily I saved a copy of nv_data.bin of SD card before screwing around.

Very interesting. Could you describe which technique you used that trashed the nv_data.bin file? We want folks to stay away from that. I just got word that my technique just worked for someone else, without trashing the IMEI or serial number.

Regardless, the process is totally reversible if you backup your files first.

Also, the carrier code in my original nv_data.bin is set to KOR, which I assume means KORea.

I guess majority want one thing: give me straight answer and I don't want to learn. Obviously, they don't have works experience where you need to get the answer yourself. There no teachers around.
Now in regards to How to flash I would recommend reread initial posts in this thread. Your check list should include:
1. Root your Tab using z4root
2. Install Root explorer
3. Copy your most important data located in the system directory, at least in the system/efs on external_sd (make directory efs_backup on external_sd). This will preserve your original IMEI and serial number etc in case of failure.
4. Initial flash beter be done using P1000XWJJ4 file set that include full ROM with proper PIT file.
I did full flash twice on both AT&T and TMB Tabs without any glitches. The only complication is the booting in Russian. This is the only ROM supporting all European languages from Bulgarian to Ukrainian.
Then I reflashed only PDA component without PIT and repartition with fresher ROM build. I also tested different modem flashing the same way without selecting PIT and repartion.
5. Assuming that all necessary USB drivers are installed, unpack your ROM,
launch ODIN, then select and point to ROM components: PDA, Phone (modem), and CSC using browse button. Select repartition if this is full reflash.
6. When everything is selected and file tab are populated you are ready to connect the TAB:
- shut it down
- put it download mode by holding two keys: "Volume down" and "Power". Shortly after pushing them together you should see yellow triangular with a digger
- connect USB cable to you Tab and computer. ODIN should identify connected Tab making one window yellow and ready message in console window
- click start and wait until the Tab reboots.
Basically that is all. Then you might need to do some checking and adjustments depending on carrier you are going to use.

Please, REREAD prior postings before doing reflashing.
