Hi I have unlocked and flashed the europe firmware with methods posted on this forum. I want to know will I still be able to update my tab with future updates like 2.3 or will it brick the device if I attempt to update it?

Thx.
[Galaxy Tab General] mazhar.abaziz:
Hi

The problem solved by going to dialer and dial *#272*imeinumber# and i choose EUK, the default is KOR

i dont know what its mean but now i can Use my 3G

I suspect you need to install Root Explorer to see those files.

Hi we got the t-mobile tab rooted and busybox is installed. Kies is installed, but it is but its version 2.0 which will not recognize the device. when typing the adb shell command, it only returns as an invalid command. What are we doing wrong?

unlock while roaming

Here it goes..

GT locked to vdf portugal (eur)

did sim unlock with hex edit

used dif SIM also frm pt (OPTIMUS)

no lock messages (success)

manual set right Apn for optimus

have data but NO TEXT OR CALL!!

Status "emergency calls only"

message "failed to register into network"

tried optimus SIM on blackberry, works fine (text and calls)

all of the above while in the UK

if no sugestions from the Masters I will quit :(

edit: checked imei and serial, all messed-up :(

should i restore .nv backup copy and retire from Tab hacking? :(

edit2: sorry guys, re-steped back with backup and did the hex edit direct on efs folder

got all services as well as imei and serial :)

now I'm happy :)

thanks for the good quality posts!
[Galaxy Tab General] ashmanu:
I have a related question. I have original T mob GT - T849 ( not flashed but rooted) and I had it unlocked from fastgsm. I inserted my AT&T sim (from Iphone) and it showed network bars, but I do not see any data and hence no internet from carrier (in this case AT&T).

I had following questions:

1. Do I need to flash my tab with EURO version to get data ability from other network carrier provider or if I can still get that by changing some settings while keeping the original ROM.

2. Am I correct in understanding that if I do flash it with EURO version, I will get EDGE+Phone with non T mobile carriers and 3g+ Phone with T mobile sim inserted or will it be EDGE + PHONE with all carriers.

3.Long-sighted but silly question: Will flashing affect/hinder in anyway the chances of future upgrade to gingerbread or honeycomb?

I know some of these questions might have been asked earlier but I was not able to find simple, straight answers, so excuse me, if this is a repost.
[Galaxy Tab General] titiubs:
Had a little trouble installing the sdk to use de adb, but i finally got it! Thanks so much roto!

Now i'm using my AT&T Tab on the brazilian TIM carrier. Your second option worked perfectly!
[Galaxy Tab General] fcarmona:
fantastic, works in mexico using carrier telcel
[Galaxy Tab General] Macneil13:
I did Hex editing as I have everything and didn't have the drivers working for my Tab.

Only difference was I had to change 00181467 and not 00181469 or 00181462 like others.

Good luck to all.

Samsung Galaxy Tab from bell with Hex Editing.

Rooted using z4root

installed BusyBox

Backed up /efs using Super Manager

installed HexEditor

Made copy of nv_data.bin

changed 00181467 from 01 to 00

then deleted nv_data.bin and the nv_data.bin.md5

then replaced with new nv_data.bin

Hello,

I have bought from amazon the Samsung Galaxy Tab AT&T model.

I still don't know if it's possible to use as a phone and I have also tried to use my SIM card here in Brazil, since I have a package data, but it is locked for ATT.

So, I would like to know if it's possible to ulock the SIM.

I've read your posts and it seems to work. But I am very naive in those procedures that you've written. First Which files/programs should I have to download on my tab (since I have wirelless at home)?

Thank you very much for your patience.
[Galaxy Tab General] fcarmona:
You have to download only to pc, then using adb you'll transfer the require files. Too easy if you know how to follow instructions.

Sent from my Galaxy Tab
[Galaxy Tab General] cgerdb:
Hi roto, it sounds like this method would be so much easier and specially for people without a computer, could you please elaborate a little bit more on this?

well of course, as an inpatient geek, I ran the code in terminal and almost instantly the phone rebooted itself. Everything works just fine like it did before, I am just going to try a friends SIM card later on tonight and will post my result back here
[Galaxy Tab General] Pullback:
I am interested to later part that involve the adb code, I am not very good on this but can understand a much simpler way how to do it. Please give a step to step instruction how to open an adb code and how to apply it in my galaxy tab. By the way I have a T-mobile GT already flushed and rooted but not yet unlock yet.

Device not found

Hi guys,

after read and read this forum thread and others related as well i must ask fro a help... cant deal with this problem longer, no more. This f******* t849 just cant be found by adb shell command. Always device not found and i cant go thru the whole proccess. During my battle trying to solve this issue got my usb bus screwled and then had to format my pc cos my interl board model DQ35MP does not have Ps2 ports. Dam**** more than 250gb of unlocking and flashing prograns installed with no ghost image saved - my problem, ok! - and 2tb of HD datas - All saved :D :D At least i can be sure it´s not a matter or android/samsung/usb driver messing up since this time it´s the very first one installed in the system. I am using windows xp sp3. I have tried android sdk tool but there they dont prompt for any usb or adb driver download / update.

Would somente gimme a tip pls? I really appreciate for n word.

Rgds,

;)

Vodafone Spain unlocked

Hi Roto,

Many thanks for your advice, I used first method by editing byte located at position 0x181469 to 00 because second one is already in 00. It works, I used another SIM card from another operator without asking me about a network unlock code (it previously does).

I also made some calls without any problem and serial# still is the original.

Many thanks again.

:D
[Galaxy Tab General] ordio:
Hi Roto,

After playing and reading for 3 weeks, i've gone ahead and done this (using ac sideload), and was able to unlock with the hex editor method.

But i did use the batch way initially and my serial # disappeared.. (the galaxy s unlock by helroz in the galaxy s i9000 forum did the same thing).

From the looks of it, the batch portion may need to be removed or modified based on post 247

Again, thanks for this! I also installed rotohammer v4 and it looks great!
[Galaxy Tab General] antoniolcrd:
At last

Managed to do this, at last. Thank u folks.

The issue were i was using my preview adb folder i used to manage g1 and older android devices. Since i switched to use the C:\android-sdk-windows\platform-tools then i could unlock it. It´s a pitty i took so long to realise such "basic" point.

I also got the errors msgs like "rm failed for out1, no such file or directory" but it was due to busybox. It prompted quickly to accept or deny su session and i lost it in the first time. ASA i hit accept everything went fine.

Thnak u rotohammer for such good job and sharing.

Rgds,

No computer required

I know the experts have strongly advised doing this on a PC, but I was able to complete the whole process on board with just wifi access to the Market.
[Galaxy Tab General] tabing:
From your computer, open an adb shell to your phone with the command:

Hi Rotohammer,

Please let me know how to do "From your computer, open an adb shell to your phone with the command". I assume on PC go to start >run>type adb shell right??? I have no idea about where to copy paste this command?
[Galaxy Tab General] rangercaptain:
Did you already install the android sdk and have the drivers?

adb runs in a command window, so start>command> opens a window where adb.exe is ran from. Do you know how to work in that environment? Paths, prompts, etc?
[Galaxy Tab General] tabing:
no i dont know how to use this environment please let me know, now i am going to install android sdk kit please let me know what to do after that thanks.
[Galaxy Tab General] abuser0815:
To everybody who wants to learn:

there is a thread in this forum (not in galaxy tab section) where the way to use adb perfectly explained in an idiot proof way.

Just search for "adb how to" and you will find this thread.

A bit more reading and searching would help everybody to keep the focus on the main topic of each thread.

Please understand it in a kind way.
[Galaxy Tab General] atamillion:
I'm new here....

Ok, I got a T-Mobile Tab from a guy that he rooted with z4root. I want to unlock it and it sounds like you got it figured out, but although your instructions are probably great for someone who knows exactly what you talking about, I'm not so sure I do. Think you could give me more of a step by step? I factory reset the tab after I got it, so I'm sure that the root manger and all that are not there or not listed in my apps. The guy assured me that I didn't loose the root. Anyways, some further guidance would be nice. Thank you ahead of time.
[Galaxy Tab General] rangercaptain:
Well said! Kind but firm.
[Galaxy Tab General] tabing:
Hi Rotohammer & all,

Your adb shell code worked

thanks
[Galaxy Tab General] armando.gsm:
very nice!! i did all procedure, but everytime when im turned off tab, always ask for code!! so,, is there a way to permanently unlock phone??? i know about codes, but probably im doing something wrong!!!:)
[Galaxy Tab General] danieljoy:
ran the scrip from adb on a US att rotojmev4 flashed tab. it did not reboot. is this normal? im unlocking in anticipation of traveling out of country but i do not have another sim card to verify functionality. is there anyway to verify the success of the unlock? i trolled google for a half hour and could not find any information. attached is a screen shot of the terminal.

This was what happened. My Galaxy tab is rooted using the SuperOneclickAPP and installed the busybox from the Market. Any suggestions? From what I see, its not able to access the /efs folder. I have enabled write access to the system using the Root Explorer app and even renamed a ringtone file to check if it was working!
[Galaxy Tab General] prajnakandarpa:

Unlocked but no data

Hey guys, i think i was able to unlock the Tab using the Hex method and was able to see ATT when i booted the Tab. I however do not get any data exchange. ( cant open a webpage or anything). I DID set all the APN settings to match ATT network settings.

Anyhelp here would be appreciated.

I am using my ATT (iphone sim) in an Unlocked Tmobile Tab.

Thanks!
[Galaxy Tab General] Tony_M:
Bell GT unlocked using Hex Editor. After entering the proper APN settings I also had to tick the Data While Roaming option. Is this normal? There's a roaming indicator above the signal strenght bars.

Other than that everything is working, phone and data.

Thanks Roto. Where's your "Donate" button?

US Pad in EU

Hi guys,

I want to buy a Tab in the States and bring back with me to Sweden. In Sweden, we use GSM900/1800 and 3G 2100Mhz.

Should I get the T-mobile or AT&T one? If I flash the EU firmware on it to unlock it, will it have 3G in Europe?

Cheers
[Galaxy Tab General] Kwith:
So I went through and did everything properly, and it all worked fine

However, my Tab won't read the SIM card still

Am I doing something wrong?
[Galaxy Tab General] camo.b:
i have a 2 day old aussie optus galaxy tab

i used the quick instructions on the first page and it was totally successful.one unlocked taB!!!!

I DID GET A FREE CODE FROM OPTUS...... but i prefer to hack.
[Galaxy Tab General] DAMCTesting:
Shell root

I know this particular user decided to go back and use hex edit but the answer as to why the above permissions were denied is because you did not have Shell Root access. If you are using SuperOneClickAPP plug the device back in and the second icon should be "Shell Root". Simply click Shell Root and when you get a pop up stating the root will go away upon reboot DO NOT CLICK OK!!! Simply go back to cmd and plug in the OP code. You should notice that instead of the $ in cmd you will now get #. After you have finished unlocking the device you can go back and click the pop up in SuperOneClickAPP, not that it matters since the device should already be rebooting. I hope this helps anyone having this issue!

[Galaxy Tab General] balthy:
If i go to an AT&T store and buy a Tab, will i need to unlock it before i can put the Euro OS on there (to activate voice)? I have an AT&T iphone sim card.
[Galaxy Tab General] rangercaptain:
You don't need to unlock your tab to flash a ROTO rom. But you need to flash the rom to get phone capability on your tab. You only need to unlock a phone/tab if you want to use a sim card from a different carrier than the one the phone/tab was made for.
[Galaxy Tab General] rangercaptain:
In the settings> wireless network you will need to select GSM, instead of the usual auto setting. The tab will get EDGE speed data.
[Galaxy Tab General] NickB95:
Help?

:confused:

I tried the 2nd method on my rooted (z4root) GSM (Vodafone Australia locked) with latest busybox from titanium backup. It rebooted, but still asked me for a carrier unlock code when I inserted my Telstra SIM from my Desire. Wat up?

Im fairly certain all drivers we updated...

Thanks in advance

Edit: my sim was not inserted when using adb, if that helps
[Galaxy Tab General] ramil315:
Hi,

I'm not an expert on this unlocking but I just want to ask a stupid question. Does this unlocking will change my IMEI no. or any system configuration that will affect the original settings if I unlock it using your method.
[Galaxy Tab General] xpgroup:
It won't change your imei
[Galaxy Tab General] SilverTT1:
Apologies in advance for the simplicity of question on an otherwise very informative thread.

If I am a current AT&T wireless customer with a Blackberry Torch with a Blackberry Enterprise Unlimited Data package and I walk into AT&T and buy a brand new AT&T branded Samsung Galaxy Tab will I be able to use the Torch SIM card in the Galaxy Tab?

I understand I may only get EDGE data speed or something but I'm just looking for light web browsing, news reading, not video or anything like that. Would this work without doing any "rooting" or "unlocking" of the Galaxy Tab?

Is there another / cheaper way to accomplish what I am looking to do?

Thank you in advance...
[Galaxy Tab General] coastalmikey:
No you will not be able to use your other SIM. I inserted my Dataconnect SIM in the tab and pops up with the message SIM not recognized and directs you to call at&t. I've called support and they can not fix the situation and the answer from at&t is that the Galaxy Tab requires its own data plan and can not be used with a CRU account unless its the $40 plan.
[Galaxy Tab General] SilverTT1:
Thank you for the info. What is a CRU account? I have a $50 blackberry unlimited data acocunt but I guess that is something different.

So is my only option to root or unlock the phone as others on this thread are doing?

AT&T Samsung Galaxy Tab Root / Firmware Question

Hi Ive just bought an AT&T Samsung Galaxy Tab, and want to both Unlock the SIMLOCK and also be able to use it as a phone (which AT&T have nicely removed), by putting the Euro ROM Firmware.

As z4Root is now removed from market and AT&T have blocked installing any app not in the market (again nice of AT&T) and Samsung KIES will not recognize US Tab's so cant get SuperoneClick to communicate with my Tab either, I'm left with flashing the ROM / Firmware.

Another problem is that cant use any of the good apps for backing up the /efs folder as I cant ROOT.

Will the firmware update erase the /efs data and / or the IMEI no?

Any other way to side load z4root?

Thanks

vpcaptain

update managed to side load z4 root with an excellent program AC Sideload Wonder Machine,

managed to root, and I am now backing up everything before attempting hex editor :-)

A big thanks to rotohammer managed to get to grips with hex editor changed one bit 01 to 00, deleted the two .bin files (after making lots of backups), and copied the new .bin file into the /efs folder and hey presto unlocked AT&T for use on Qtel / Vodafone which is working great here in Qatar (middle east)

unfortunately the script program for changing the bin file doesnt seem to work, i copied it exactly and wrote a script file and run it through Gscript like as described but it just sat there and didnt appear to run, with no changes to the bin files. hence getting to grips with the hex editor, much simpler.

a big thanks again to rotohammer - next step the euro rom, but concerned that i might lose 3g functionality but what the hell if i can use it as a phone bingo!

Are all galaxies’ specs the same?

I’m a Canadian and I am tablet less as we speak.

On Samsung’s us web site; specs seems to differ depending on provider!

Do I have to expect different specs depending on origin?

I own a nexus that I got from Google store and I love it… Do I just get any Galaxy on same band as my provider, unlock it, and “Voila” a giant nexus one with all specs running? (Phone, gps, Wi-Fi, 3g etc…)

And/or! If they’re all the same! Is there a way to reinstall android? Isn’t-it a shareware open source or something?

ps. Good input you have here. Thank's :)

[Galaxy Tab General] SilverTT1:
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?

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?

Thank you for your advice.
