Two questions:

1. Can you use the instructions in the first post of this thread to unlock an AT&T Galaxy Tab to use with a sim card from another AT&T phone/blackberry that has an unlimited data plan?

I'd like to know the answer for that as well.

2. If you do this process and then later return the Galaxy Tab is there anything you can do to reverse all the rooting/unlocking you have done so the carrier does not know you have messed with device? Said another way can you re-flash to go back to stock somehow?

Yes there is att stock ROM you can flash back to it
[Galaxy Tab General] freeman9911:
how would I know that it's successfully unlocked while I don't have other carrier's SIM card?
[Galaxy Tab General] rangercaptain:
You can't use a blackberry plan, but you can use another android plan. Blackberry uses it's own network, BIS-B, for the push email and pin messages.
[Galaxy Tab General] rangercaptain:
Then does it matter anyway? You could ask to borrow someone else's sim to check your unlocking skills.
[Galaxy Tab General] SilverTT1:
Is this true? I have used the Blackberry Torch to tether to a PC (without paying the tether fees) without any issues before. If this is true then I am screwed.
[Galaxy Tab General] rangercaptain:
If you put a blackberry sim in your tab, your carrier will force you to switch data plans.

[Galaxy Tab General] JojoSFO:
Hi, I know it's kinda off-topic, but also kinda related to a discussion earlier on this thread:

T-mobile blocks net access to their network from their Galaxy Tabs through IMEI, or so I gather from this thread. My question is: Do they have all Galaxy Tab IMEIs in their db or just the T-Mobile Galaxy Tabs?

Can I use a non T-Mobile unlocked Galaxy Tab on their network with a regular SIM (and not with their Webconnect plan)? Will I get internet access then?
[Galaxy Tab General] cheema:
I used this method to unlock my T-Mobile Galaxy Tab. After doing this, the Tab accepted the AT&T SIM card without a problem. However I could not make a phone call as I had hoped that I would be able to. The call tries to go through but is immediately dropped.

Is anybody able to make a phone call on a different network with an unlocked American Galaxy Tab?
[Galaxy Tab General] Bugman1:
you probably need to change the APN settings to AT&T settings.

rotohammer,

have you been able to get the mod for cellular voice traffic to work on the TMOUS version.?

I want to get a SGT, but since i am TMOUS, did not want to go that way, unless it will work.

U have PMs turned off, so this is the only way I could contact you.

thanks
[Galaxy Tab General] cheema:
> you probably need to change the APN settings to AT&T settings.

APN is for data. And probably has little impact on voice calls. I was hoping to be able to makde voice calls with my unlocked TMobile Galaxy Tab. I did find the following page that looks promising:

http://www.thegalaxytabforum.com/in...-att-galaxy-tab-to-make-calls-1900-850-wcdma/

I am hoping that the using the Bell Galaxy modem as described in the article above, I would be able to make voice calls.

At&T Tab attempting T-Mobile SIM

Long time reader first time poster...

I got a brand new At&T Tab today I performed this:

http://xdaforums.com/showthread.php?t=929479

To enable phone.

Then I ran OP's script to unlock it so that I can use a T-Mobile SIM.

Everything seemed to go fine. But now I have voice, meaning I can make/receive phone calls. But there is no data, no E, 3G or anything.

And as of 10min ago there is nothing listed under Access Point Names all I get in that screen is "No Items."

So I added a new APN and now after an hour I have been informed that my T-mobile SIM wasn't just T-mobile it was a Jazz Wireless SIM which operates on an entirely different APN. I am now 100% functional with voice and Edge.

Thank you anyway!

Greetings

A friend of mine bought a t-mobile Galaxy tab and now he lives in Saudi Arabia.. I managed to Sim Unlock his tab following your commands on adb, however it only sees one carrier out of our 3 cariers in Saudi Arabia... I tried changing the modem but that didn't solve the problem... is there a way of fixing this? or the US version has different GSM bands than the other variants?

Thanks

Worked a treat on the second attempt. For some reason it errored out first time I pasted to the shell but on reboot of the tab and re attempt came back up unlocked.

difference between OP unlock procedure and legit unlock code

Hi,

I recently bought a US T-Mobile GT from someone, and Tmobile is giving me a hard time to get an unlock code.

I am therefore considering the OP procedure but have two questions.

He mentions that after doing the unlock procedure, you have to manually enter the APN.

1) Does that mean that everytime I want to use a different carrier I need to find and change the APN

2) When unlocking the Tab using a legit Unlock code from T-Mobile, do you also have to manually enter the APN of the next provider, or is it automatically detected like on a regular cell phone?

Thanks for any clarification
[Galaxy Tab General] rangercaptain:
90% of the time the carrier sends the apn data to your phone, then you just select it in the apn settings screen.

If it isn't there, I just borrow someone's andriod and copy their settings.

Root

Search for Z4root in this forums, after that install it (if you do not know how to use adb search google for a guide or just use your device as an external hd, paste the apk there, and using "My Files" locate it and install it)

Under Settings > Applications > Development > USB Debugging should be checked

After that just run Z4root and select temp root (if you just wan to check it out)

or perm root (if you are ready to root permanently...)

Crazy weekend! Carrier re-locking and battery droping

Hey there! If it can helpful, Yesterday I was watching some videos on Youtube when I started having a lot of trouble with battery DROP. I Still didn't fixed it out but I'll probably take out the battery for 15 min...

But the thing for this topic is that after reseting it a couple times, i don't know how but my tablet RE-LOCKED! Really, it was asking again for the Network Unlock Code.

After trying to find someone with the same symptoms which had no luck, I decided to re-make the carrier unlock of Roto.

I can confirm by my experiment that having 00 in both addresses allows to use non t-mobile sim.
[Galaxy Tab General] Croak:
I can confirm this works just fine on a Bell GT-P1000M (SGH-I987), so this should unlock AT&T and Rogers units which are the same device.

Just like Volker1, I made no changes to 0x18150e.

It's fully working on 3G using my Telus Voice/Data SIM, but of course I had to manually setup the Telus APN data.

This, by the way, really rocks for me. My Telus plan gives me free data roaming in the US (rather, it uses my domestic data bucket), my Bell Tab plan is $3/mb in the US. I spend a fair amount of time down in the US away from WiFi. This will come in very handy.

Now, debating if I want to flash the Euro firmware/AT&T modem combo to enable voice on Telus too. :)

"0x180069 to 0x1800ce: change all these bytes from the values they are to ff" ?
[Galaxy Tab General] Croak:
A good chunk of those in that range were already FF on my unit.
[Galaxy Tab General] rgbc:
rotohammer, thanks for this, my Bell Tab is up and running with my Rogers phone sim.

I had to give myself a bit of a refresher on hex editing but your tutorial very straightforward. For 0x180069 to 0x1800ce over half were already FF and 0x18150e was already 00.

Cheers,

@roto: Did you already have a T-Mobile account? With me, even mentioning having paid full price, they say there's nothing they can do before 40 days. Do you have any names or direct contact numbers (e.g. to the department to whom you faxed)?

Thanks,

[Galaxy Tab General] rotohammer:
I'll be glad to list all the info. But did you consider making the one or 2 byte change to unlock the phone yourself? Its easy and even reversible if you want to still get/use the official code. I hacked mine, then 4 hrs later I got my code, reverted everything and then used the code.

Theres no real advantage to the official code.

@Roto - thx much -- I have been monitoring this post for a few days in anticipation of returning my T-Mo unit in favor of AT&T which I picked up yesterday -- I can now do that. It's been a few years since I fired up a hex editor, but it's like riding a bike, they say... ;-)

Will research the rooting & backup procedures before I take the plunge, but would like to get your opinion on the following:

1. Right now, I am mostly interested in unlocking the Tab for use in Canada and EU on business trips. For that I simply need to root, backup efs folder contents, and unlock - correct?

2. If I later choose to enable phone/SMS capabilities, I will need to flash the unit with the Russian & EU rom's, plus obtain SIM(s) which is/are authorized for 1)phone calls, 2)SMS, and 3)Internet access. Not knowing how the AT&T computers track the useage, I assume I have the options to 1)add a new handset to the family plan, or 2)use a 3rd party prepaid SIM. If #1, should the new handset be an Android-based unit, or can I choose the cheapest one I can find?

[Galaxy Tab General] flydeep:
If your device was sold by ATT, they have your IMEI number in their database. Most likely they will find what device you are using. After that you are under their mercy and may slip the radar until they decide to force the plan on you. If it Tmo branded, you will not get 3G speeds but you should be able to fly under the radar.

@chr2303, do you want to explain further please?

Later edit: I did it guys, with the first method. Is plain simple. For the hex editing part I did use HxD (seems like I cannot post the link, but the first result in google will do it). Make sure you have enough copies of nv_data.bin (or to be sure the whole efs folder).

I've tried to replace nv_data.bin from ATT tab to TMO tab, it seems to be working fine on t-Zones, but the IMEI number does not look right - starts with 00.

Did yours just ask for code as soon as you powered on?

[edit] Seems you have to swap sim cards while powered on, let it reboot and then it asks for you code :)

Works well, thnx :)
[Galaxy Tab General] rangercaptain:
Install the app. Run the app ~ takes about 10 minutes. Write down code. Shut off tab. Take out carrier sim. Put in another carrier's sim. Start tab. Upon boot, tab will ask for the code. Do it. You are unlocked. Donate to chainfire. Done!
[Galaxy Tab General] TheATHEiST:
That doesn't work on UK T-Mobile Tab. If you power off with original sim inside the new sim wont be seen and you will just get "no sim inserted".

The only way I could get it to work is to remove original sim while powered on, it will automatically reboot, insert new sim while rebooting and upon it booting back up it will ask for code.

Not sure if this is same for all tabs but it definitely is the way on UK Tmobile or mine at least.
[Galaxy Tab General] Bmanride:
Used the second method, worked perfectly even though it was a pain to understand how to make ADB work. Thanks alot.
