[GUIDE] Flash T-Mobile Galaxy Tab so that it makes calls with any sim (EDGE only)

DISCLAIMER: I AM NOT RESPONSIBLE FOR YOUR ACTIONS. IF YOU BRICK OR DAMAGE YOUR DEVICE IN SOME WAY, IT IS YOUR RESPONSIBILITY. THERE ARE SOME STEPS THAT MIGHT NOT BE LEGAL IN SOME COUNTRIES (CHANGING IMEI NUMBERS), AND I WILL NOT BE HELD RESPONSIBLE FOR THAT EITHER. EVERYTHING YOU DO WITH YOUR DEVICE IS YOUR OWN RESPONSIBILITY AND IF YOU FOLLOW ALL THESE STEPS YOU ARE AGREEING TO THAT. THIS TUTORIAL IS DONE FOR EDUCATIONAL PURPOSES.
Thanks to clubtech, rotohammer, koush, ayman07 and everyone in xda that has worked hard to make this possible. I did not come up with any of this, I only gathered it all from different sources and smashed it all together in an easy-to-read guide. Credit is due to all of those listed above, if I missed anyone please do let me know and I'll gladly add you here.
You will need
- P1000XWJJ4 firmware (pass: samfirmware.com)
- P1000XXJK5 firmware (pass: samfirmware.com)
- Odin 1.3
- Koush's zImage for T-Mobile Galaxy Tab
- flash_image
- I900AOJP3.bin Modem from HERE
1) Put you tab into download mode (Turn it off, when it's off, Press VolDown+Power until you see a yellow android and it says downloading...) (WARNING: All your data will be lost in the next step! Everything, INCLUDING the internal memory! Make sure to back everything up to your computer!)
2) Use Odin: Flash P1000XWJJ4 (PDA button) with P1_add_hidden.pit and make sure "Re-partition" is SELECTED, press Start and wait for it to finish. The device will reboot and it will turn on again, probably in russian.
3) Turn it off and put it on download mode again.
4) Use Odin: Press the reset button, then make sure "Re-partition" is UNSELECTED and there's NO PIT file, then flash P1000XXJK5 under "PDA".
5) The device will reboot with the latest euro firmware in english. The modem will probably be undetected, the device will be working kinda crazy (It might be slow and whenever you use something that uses the vibrator it'll get worse, the vibrator won't probably work, don't worry about this, it will be fixed in the next few steps)
6) Make sure you have flash_image and the tmobile_zImage in hand and issue these commands:
Code:
adb push flash_image /data/local/bin/flash_image
adb push tmobile_zImage /sdcard/
adb shell
su (make sure to select "Allow" when the Superuser dialog pops up on the tab)
chmod 755 /data/local/bin/flash_image
/data/local/bin/flash_image boot /sdcard/tmobile_zImage
sync
exit
7) Now, the kernel should be flashed, a reboot should fix all the weirdness. However, instead of rebooting, turn it off, and put it on download mode again (VolDown+Power)
8) Use Odin: Press reset on Odin, make sure "Re-partition" is UNSELECTED, and on the Phone button, flash the modem I900AOJP3.bin.
11) Wait for it to reboot. At this point, the tab should work fine, and the modem should be detected by the system. However, you won't be able to make calls or use the internet because T-Mobile is blocking data. Now, we need to change the IMEI number (READ DISCLAIMER ABOVE!)
12) Now, we need to backup all the contents in the /efs folder, that way, the IMEI will be corrupted, we want this to happen because T-Mobile is blocking the IMEIs on all T-Mo Galaxy Tabs so that data doesn't work unless you have the right plan/contract (BAD MOVE T-MO! WE DIDN'T EXPECT THAT FROM YOU, AT&T MAYBE, BUT NOT YOU!)
13) Backup the /efs folder (Notice: you must have busybox installed, get busybox installer from the market)
Code:
adb shell
su
busybox tar zcvf /sdcard/efs-backup.tar.gz /efs
busybox cat /dev/block/stl3 > /sdcard/efs_dev-block-stl3.img
exit
back to the shell in your computer, now use these commands to put those files in your computer, and save them somewhere safe.
Code:
adb pull /sdcard/efs-backup.tar.gz .
adb pull /sdcard/efs_dev-block-stl3.img .
14) Delete all contents from /efs and reboot. Easiest way to do it is using root explorer from the market. DO NOT DELETE THE ACTUAL FOLDER, JUST IT'S CONTENTS.
15) Done, you will be able to browse the web, send/receive SMS, and send/receive voice calls. The only issue at this moment is that it will only work on EDGE, 3G is not possible, YET.
Enjoy.

Where exactly? Please link me to the post that makes your T-Mo Tab make calls, using the Euro firmware and vibrator works and the tab doesn't go crazy.
As I said, all the guides I found were missing a few pieces. One was for AT&T Tabs, but I didn't find one that was for T-Mo tabs in a single piece, everything was scattered all around.

Oh ok, didn't notice that also works for T-Mo tabs. Oh well.
Thanks.

Thanks for posting this guide. I followed the instructions and still cannot make phone calls. It seems to dial but the T-Mobile automated voice operator says "The phone you are using does not allow outgoing calls."
I removed all /efs files and rebooted, then verified that the IMEI was corrupt afterwards.
Any ideas? Maybe T-Mobile is blocking the corrupt IMEI number now?
Thanks in advance!

Are you able to use the market ok with your imei corrupted?

I don't think so. Are you using a SIM card with a plan that has phone calls or are you using the same SIM card? Your Tab has a webConnect plan that does not allow phone calls, so you need to put in a SIM card that has data and calling plan.
They are blocking the IMEI for data, as far as I know, so if you use your tab to go online (without using Wifi), and it goes to my.t-mobile.com even if you try to go to xda-developers.com then they are blocking it, but in your case, it's just probably the calling plan.

If you only do :

done it but still nothing..
is it my rom or what??i'm using NDT ginger..

Works for me. Thankx.
One more thing. If you actually have root explorer, there is no need to use adb commands. Just replace the apns-conf.xml file in /system/etc/ and reset permissions as rw-r-r and reboot device.
Once rebooted, go to APN and press menu, then press Reset APN to default. Worked for me.

Hi !

that should not be ... is that the international version of B107?
try to make factory default, think that should work or try to reflash the B107 ...
good luck

Have disappeared because they match the folder path CUST.
First you must be ROOT
Second with Root Explorer app, go to the folder "data" and see the contents of custom.bin
Depending on the file custom.bin say, is as it should rename folders CUST.
For example if it says "Orange/dm", that means that inside the folder "CUST" the folder must exist "Orange" and within it another folder "dm".
If not there you can rename the folder "Channel" to "Orange" and within it you choose to rename the folder to "dm" much of the country that depends on where you live, could be renamed folder "namerica" to "dm" or "neeurope" to "dm"
Finally do a factory reset
Best Regards

Try installing B111 international rom and revert.

"custom.bin" method does not work. For some reason I have "unicom/cn" inside custom.bin. Tried to change custom to Orange/Dm does not work. Tried to rename Orange directory to "unicom" and dm Directory to cn does not work.
Anyway thanks

Of course, if it works, I've tried several times and if it works.
Maybe I did not understand the procedure.
I'll try to explain it better:
1. You must be ROOT
2. Having installed the app Root Explorer
3. Log in to Root Explorer and find the file custom.bin
4. You must remember the contents of this file.
5. Go to the root folder, using the Root Explorer
6. Go to the folder Cust
7. Rename the folders according to the content of step 3.
8. Perform Factory Reset
At no time should change the file contents custom.bin.
Best Regards

succed the process, but bring more painful problem.

Well I got it working. Now I cannot comment on the exact steps above as I had already applied the other "permanent sim unlock" procedure. I can tell you what I did though.
-I did not remove my sim. I don't think that step is necessary.-confirmed not necessary
-I copied the carrier files to carrier/apps
-I copied the files from etc folder to etc
-I left the apn-conf file from the previous unlock-This is necessary
Reboot
This gave me signal, but no data
-I entered ##DATA# in the dialer
-Hit APN Setting
-Hit menu button, and Reset to Default
BAM... GSM signal shows up, I have data working.
Also confirm the hands free activation didn't appear after the steps above.

Take a look through your apn-conf file and make sure your APN is listed properly. Make sure you rebooted your phone, it often needs that to pick up APN. If it's there, try resetting to default again in ##3282#. Hope you get it working.

Possible to sideload older version of 'Advanced Info' ?

I'm trying to interop unlock my Lumia 550, but it seems the Advanced Info app has updated as when I get to step 2 of unlocking in the vcReg app, it just crashes. Is it possible to download and sideload an older version of the app to allow me to finish the interop unlock?

No

Sideload.
Just erase -zip extension.

It doesn't work. I have a Lumia 550, so I click on Restore NDTKSvc (x50) and it says it didn't find the file. However, I accidentally toggled the one for non x50 devices and can't figure out how to undo that, so maybe that is my issue.
