Greetings all! I just flashed my AT&T Tab to Gingerbread using video instructions found at thegalaxytabforum (sorry, I don't have enough posts to post the link)
Unfortunately everything works good except the 3G part. This thing doesn't seem to be connected to the AT&T network. Wifi is good.
I'm new to the flashing business so I'm really lost at this point. Any suggestions on what I can do to get it connected? I'm even willing to go back to the stock installation of Froyo if that's what it takes, but I really like the Gingerbread update.
Any insight you could provide would be greatly appreciated!
Update: I've now flashed to the Overcome ROM and I still don't get any connectivity. I included the modem file when flashing but still nothing. What am I missing?
which modem file are you using?
One user reported ok using JPZ modem in AT&T but you may need data plan because AT&T know you are using a tablet.

Flash from CWM recovery. Couldn't be easier.
I have a data plan with AT&T and I've tried a couple of different modems. It eludes me.
Forgive me if this is a stupid question, but what is CWM Recovery? I like the sound of "couldn't be easier".
you have overcome ROM. Overcome kernel comes with recovery.
Put your modem zip files in the sd card.
If your tab is powered up, press the power button, and the reboot menu has one called "Recovery".
You can also reach from powered-off state, by holding VOL UP button and power button.
That is ClockWorkMod recovery.
Choose to "install" from sd card, and navigate to your modem zip file.
EDIT: have you confirmed your problem is not with APN setting? GPRS/3G service needs correct APN setting to work.
The only APN showing is ATT wap.cingular. I have no idea if that's correct. I could add another one but I don't know what to add. I just reset my APN defaults but that didn't seem to help.
What modem zip files are you referring to? Again, sorry for the silly questions. This is indeed my first rodeo.
I really appreciated your help!
wap.cingular sounds right.
What link, read my original reply.
Before that, can you note down your "Setting | About Phone" Baseband
that is your modem version. In case you need to know that.
I went through all 24 pages of the modems thread and installed 4 of the modems that were recommended for AT&T but still no data connectivity.
Thanks for the help so far. Any other suggestions are certainly welcome.
By the way, I have a friend with the same un-flashed tablet. Is there a modem file I can snatch from her tab and install on mine? Just a thought.
to get modem, your friend need to have rooted tab.
I am just giving rough idea below and I don't know if it safe or not, or if you know how to use adb, heimdall or Odin.
(borrowing what "roto backup" script use)
and using ADB
adb shell su -c "dd if=/dev/block/bml12 of=/sdcard/modem.bin bs=4096"
adb pull /sdcard/modem.bin .
but you will need to use heimdall to flash modem
or tar it and use Odin.
Again, I can't help you with all these, so if you are willing to learn and to try..

I have successfully installed the Roto/JMI v2 Rom on my Verizon Galaxy Tab.
It seems to work, but somehow I lost my modem. Where can I find the CSC/Phone firmware to reflash using Heimdall?

did you roto back first before anything?
Here is the modem.bin file extracted from my Verizon GTab. It worked to fix my modem when I mistakenly placed the zImage file in modem slot for Heimdall.
Used 7z to compress. Just uncompress and use Heimdall to update.
Let me know if this works for you...
when I use that modem.bin, heimdall with go to install it then sit at 100% but doesn't actually install it. It locks up, when I restart I get the phone exclamation mark computer error picture.

Hmm, that shouldn't happen. How long did you wait? Heimdall will wait quite some time (sometimes 5 minutes or more) for the phone to respond. If the phone doesn't respond in this time then you should see an error message.
Anyway if the modem flash did actually make it to 100% then you should be able to use the command line tool directly to just get rid of the phone exclamation screen:

Thanks for your response. I ended up re-flashing the Stock Firmware, and it worked.

Golden422 - How did you do this, what files did you use?
I have the exact same problem you were having, no luck for me.
I still stuck on airplane mode with no GPS.
If it means anything, under "About device" I have unknown Baseband and Hardware versions.
Thanks in advance.

Same. I have no 3G network. I am also stuck at the 100% loading screen. Help would be awesome.
You guys should check out the Gingerbread leak for VZW that Oldmacnut posted in the development section. It's a full stock GB rom. Otherwise I'd recommend his Better Than Life rom. The stock GB should get you back up and running, then you can figure out what you want to do from there. There's also a stock Froyo rom floating around here for the VZW tabs as well. The Sprint rom breaks the VZW tab's 3g, known issue. You always want to try and get the stock rom for your specific tab.
The Sprint install breaks my modem? How unfortunate. Anyway how do I put a band-aid on it to fix it? Lol
Hope I don't have to send it back to get it fixed...
Sent from my SCH-I800 using XDA App

Oldmacnut is my hero! Love the GB release too.
Somehow while Rooting and Updating I lost all 3g service on my Verizon Tab. This is a replacement Tabe sent to me by Verizon. When I tried to restore the info from my prior Tab this one came up "No Service" I tried going back to stock, all the previous backups still on my SD card. Nothing works. Anyone know what I need to do to get the 3g back......
Oh ya
The baseband version is unknown
http://forum.xda-developers.com/showthread.php?t=955342
You need these I had a similar situation, but these are all the files you need including the modem for 3g
I followed those instructions when I tried to go back to stock. Do I just need to add the modem file in the modem spot in Heimdal or do I need to put all the original file back as well?
i did a complete reload when i did mine using heimdall
Hold down power and volume down to get into download mode.
factoryfs.rfs in factoryFS
zimage in Kernel(zimage) and recovery
this is important read carefully before selecting
there are 2 param. files you want the param. lfs it goes in param.lfs slot
cache in cache
and modem in modem
Those are the only files you will need. It worked from me I have been working on themeing the tab using the deodexed roms posted in development so i have really got stuck before and these have saved me everytime. Hoping to post and accurate battery mod ported from sbrissen over on the fasc forum he has been helping me on it and i think i have a stable version
hope this helps

No luck, tried flashing the files twice no change. Still no 3g and the baseband still says unknown.
you said after you restored from your previous tab, What happened to the previous one? the same thing? and how did it get that way?
On the previous tab I was running KhasMek's K-leanMod v3’s Rom and KhasMek Voodoo Plus v5 Now with Full Voodoo CwM Kernel. I wanted to go back to stock so I could get the latest Verizon update. I wanted the Bluetooth HID access. After I converted back to stock I was unable to load the update. It would download but not install. The Verizon tech was unable to help me so they sent me a new one. I realized that I forgot to disable the lag fix before I went back to stock.
This time I Rooted (using super one step root), installed Titanium backup and installed my backed up apps. When I rebooted I lost the 3g service.
did you remove root and tb b4 you tryed flashing the stock files? Also did you have voodoo active if so deactivate before flashing back to stock.
I have a Model SGH-T849 Galaxy Tab, Firmware V 2.2 from T-mobile
I've been reading that a European version of firmware will allow some tabs to be used to make phone call. ([How To] Flashing Euro Firmware on Samsung Galaxy Tab Video Included) I found this thread...
Will this work on my tab?
I would like to know before I start and brick it.
I've been reading and reading, but have not found a defitive answer.
Thanks in advance for any info or ideas.
Any rom besides a stock t-mobile rom will enable voice, with a compatible modem. Don't mess with that thread on installing a euro rom - that's so last year.
Flash the stock-safe JQ1 rom, flash the CF-Root v3.3 kernel to root the tab, then install the Rotohammer modem switch.
With this set-up, which is what I have on my t-mobile tab, you will have to switch between two modes: 1) voice+EDGE data and 2) 3g data only, but you can't have both.
Rangercaptain, You've been very helpful...

I presently only use the tab for wifi. Its more of a toy. I used you post for using it in airplane mode and turning off data. It works great, thanks.
I don't need edge or 3g, I really don't even know what they are. Only tmobile voice and wifi.
I have not rooted the tab because i have been unable to figure out how...I know there are two ways, oneclick and x4root, but am afraid to screw up my tab.
I need a step by step instruction to get it all done. Any help will be appreciated.
Thanks for all you help and support so far.

rangercaptain,
I downloaded: CF-Root-TAB7_XX_OXA_JQ1-v3.3-CWM3RFS and Odin3 v1.7. From this thread: [11.05.2011][CF-Root v3.3] JJ*, JM*, KA*, JQ1 - su+busybox+CWM3/RFS
Am unable to find Rotohammer modem switch.
Am I going in the right direction?
I use the Odin3 to link the tab to my computer and then flash JQ1. I then flash Rotohammer when I find it.
Thanks.
You have everything ready, except the roto hammer modem switch files.
1) flash the JQ1 rom to get gingerbread. There are two ways to do this, one from chainfire, or one from team overcome (they call it stocksafe v5).
2) flash the CF-Root v3.3kernel to get the root permission.
3) add the folders, files, and app to make the modem switch.
At this point you will have stock, rooted gingerbread on a t-mobile tab that can make voice calls.
You will have to do one final procedure to use a sim from another t-mobile smartphone and get the 3g data working:
1) Back up the /system/efs folder to your pc.
2) delete the files in the /efs folder on the tab.
The t-mobile wifi calling app isn't as good as skype, and can't do video calls.
Help, what have I done???

Followed the instructions to the "T" and can now make calls using my T-mobile sim card in my TAB. I'm still not sure what I did, but it works.
Thanks to Rangercaptain and the others on the XDA site.
You can't image how happy I am...It made my day.
Now flash the CF-Root file. You will need root when you come back asking about 3g.
Howd you get so smart???

I have a 7" tab that was given to me by work, for work. I use is mostly for the 3g hotspot, but I've noticed that the internet lags pretty badly. It constantly hangs, and freezes up. I have a samsung fascinate that I'm running miui on, and when tethered to it the internet runs great. I'm wondering if this is a radio issue on the tab, or if I maybe need to flash another kernel to fix the lag that I am experiencing with the stock software. I don't want to flash any roms, as I don't really use the tab for anything other than as a 3g hotspot. Any help would be greatly appreciated.
Ok, I see that there is an EC011 modem available. Is that compatible with the stock froyo, or is the stock froyo the issue? I'm starting to think that the modem isn't the issue, and I'm going to need to flash GB or a custom froyo rom to fix the issue. Anybody else have this issue besides me?
So.....I've decided to flash the 2.3.4 leak. It's my first time using heimdall, so I want to make sure I have the method straight and have all of the items i need. I just need to unzip the file, then select the appropriate files. Then, I need to select a modem and recovery. Do I use the zImage for the kernel and the recovery, and is the EC011 modem compatible with the gb leak? Any help before I mess something up would be greatly appreciated. Thanks in advance.
the modem (which you call a radio) should have little to no impact on the rom itself.
most kernels should have the recovery built into the zImage file, so only put it in the zimage slot in heimdall. Only put something in recovery if there is an actual recovery file in the tar you have extracted.

Yeah...I was at work, and got my terms mixed up. I ended up flashing the stock gb leak with heimdall, then flashed the modem.....soft bricked it somehow, then reflashed the rom. All came up well, but the 3g hotspot was still slow and buggy. I decided to try barnacle wifi, which I use on my phone, and that solved all of my issues i was having. I'm guessing the 3g hotspot verizon app is just flawed. After installing barnacle, I ran a few speed tests. I consistently hit 2.5mbps down with almost a meg up. With the 3g hotspot app I hit 300-400k down, and 500-600k up.
So my mom is using my "old" Captivate. When she was on the beta version of Android 2.2, the data and cell connection kept turning off and she would have to restart the phone in order for it to work again.
I updated the phone by flashing Android 2.3.5 (I897 UC KK1). It was working totally fine and then it started to have the same issues as before.
I was wondering if anyone could be kind and help out.
If a new modem needs to be flashed, how do I do that?
As of now, there is NO root on my mom's phone since she doesn't care about that stuff.
All help is much appreciated!
PLEASE? Someone has to know......
You can try other modems. You need CWM to do that. Flash a kernel with CWM and then flash from the huge list of modems that can be found at Oxicottin's thread
I believe you could also extract the modem.bin from those zip files. You could then place that modem.bin in the PHONE slot within ODIN and just flash the modem itself without ever changing the kernel.
Please someone correct me if I am leading him wrong. This would require him to only flash with ODIN once and still keep his stock kernel.
You are right that can be done as well.

It's been so long since I did it that way I was trying to remember if I was correct. I've been spoiled by all the DEVS making CWM packages.
