Please note that i am not responsible if you brick your Galaxy Tab.
This worked for me and i now have a Galaxy Tab, on At&t making calls + 3G data + 850/1900Mhz WCDMA enabled.


**please note you need to have a SIM card with a proper voice plan and DATA plan for this to work. do not try this with the prepaid card that came with the Tab.


1) Download the firmware P1000XWJJ4 from HERE (pass: samfirmware.com)
2) download the firmware P1000XXJK5 from HERE (pass: samfirmware.com)
3) download Odin 1.3 from HERE
4) download the modem_bell_i9000.zip file attached to his post and extract it.


A) put you tab into download mode and flash P1000XWJJ4 with P1_add_hidden.pit and repartition selected. The phone will reboot and will be in Russian.

B) Put the phone into download mode again. flash P1000XXJK5 with NO repartition and NO PIT file. the phone will reboot with the latest euro firmware in english.

C) finish the setup wizard, if you do not get DATA at this point (3G or EDGE) at this point go into APN settings and change the APN from "Broadband" to "wap.cingular"

D) Put the Tab into download mode and flash the attached modem.bin file (the one you extracted) by selecting the bin file under "phone" in Odin. NO repartition and NO PIT file.

E) At this point your phone will reboot and you should have 850/1900Mhz enabled and everything you should work just like the euro version of the Tab.

Done and done.


UPDATE: I found that at&t are disabling HSUPA on the Tab, thus using the at&t original modem will not be ideal. I found that the Bell Galaxy S 2.2 modem is the only modem i found so far that will give us 850/1900Mhz + HSUPA + voice calls.
Please flash this modem instead. it is attached.

Because it is the only real full flash firmware we currently have and that fixes the boot logo problem i had when i didn't do a full flash before.
XXJK5 is not a full flash, but incremental one so we have to flash twice.

Wow you are a real genius , this tab just cameout today and u already found a way to make the voice work compared to the other post here about flashing their tmobile tab still scratching their butt trying to figure out how to make it work. Can you help us tmobile user to make our device working with voice and 3g? I got 3 more days to return it and get at&t.

T-mobile are blocking the data plans by IMEI, so there is nothing we can do unless you want to fake your IMEI.
As long as the IMEI stays the same, even if you got 3G and voice to work, data will still be blocked on regular phone plan sim cards so there is no point really.

For blocking by IMEI T-mobile should see all their tabs returned as far as i care.

so if i get a att tab do what you posted and unlock it then add my unlimited t mobile sim will i still be blocked?
It shouldn't be blocked (unless T-MO is blocking ALL Tab IMEI's, not just their own), but even so you'll be unable to use 3G, it'll be EDGE only, since the AT&T device won't support T-Mo's AWS frequencies.

A small update.
So it appears that at&t have disabled HSUPA so the upload speeds are slow (it is capped around 386Kbps).
I tried flashing the Bell modem.bin. it kept the 850Mhz and disabled the upload cap but i could not longer make or receive calls.

Flashing back to the at&t modem back and i was able to make calls but the upload speed is again capped.

Thank-you at&t!!! for crippling my hardware!!

Anyone can post the modem from Rogers? that would be helpful to try.

On step a), it's really a 2 steps process right? Meaning

1. Download the pit file
2. Flash the PDA, Phone and CSC

according to general flashing instruction here http://www.samfirmware.com/P1000 how to flash.pdf ?

And when come the 2nd flash, skip the pit file and flash the other 3: PDA, Phone and CSC?

Thanks again.

and what do you lose from corrupting ur IMEI #? i see nothing but gaining from it.

Ok, Bell GT-P1000M is now flashed with JK5 and the AT&T Modem, and is fully voice and data functional on Telus (I manually unlocked it) in both 850 and 1900 bands.

Rock on.
