I haven't found a single thread that has any information/files necessary to go back to stock on the 10.1 LTE tab. Does anyone have any of this information? Is anyone able to pull the stock radio from the LTE tab? I used this file "samgtab10.1_lte_root.tar.md5" via odin. Ever since i did, my tab doesn't get 4G/3G service anymore. Seems like it was the wrong radio in that odin file or something. Any help would be appreciated.

I successfully flash from Roto pre-rooted JME v4 rom back to stock ATT rom ( also provided by Roto ), and to JME v4 again.
What I did in last couple of days:
I got the ATT tab and didn't activate the SIM card. I rooted the tab and flashed the tab with Roto pre-rooted JME v4 rom ( as mentioned in many posts, root is not a pre-requisite of flashing Roto's rom ).
I used an iPhone SIM card in the Tab. Both the voice and data worked. I even got 'H" ( HSUPA) on the signal bar while the iPhone with the same SIM card only shows '3G', probably because I flashed the Tab with Bell modem.
However, I found it is not very convenient for me to use the Tab as the main phone. So, I want to activate the original SIM card that comes with the Tab and only use data on Tab, which I thought I could only do that by using the stock ATT rom ( if anyone knows a different way, you can share it ).
So, I used odin and flashed the ATT stock rom posted by Roto. The flash process is very easy. NO re-partion, no PIT, no modem. I just put the ATT stock rom into 'PDA' part in the odin and click 'START'.
After I flashed Tab back to the stock rom, I even got back the Samsung logo. No more black screen with bright line. Everything seems to be back to original state except that the tab still shows it is rooted when I check the firmware version ( I used super 1 click to root the Tab. Tried different ways to un-root. But the kernel still shows 'root'. If anyone knows how to completely unroot, please let me know. Thanks).
Since the original SIM card has been activated, I thought it might be better to flash the Tab again to JME and Bell modem. So, if I really want to use a SIM with voice plan, I can.
Flashing to Roto's JME v4 for the 2nd time was very easy again. I just followed the quick tutorial in this forum ( I did the re-partition. maybe it is not needed). Everything went smoothly. The only caveat is that I got the single bright line with black screen during booting for a couple of seconds.
Now, I am back on JME with Bell modem and original data-only SIM card. I set the APN to the settings for data-only SIM. The original SIM card just works.
I found a lot of ppl asking about flashing back to stock rom. I feel it may be useful to share my experience. Sorry for I didn't put the references to the posts regarding flashing and rooting.
Big thanks to Roto.
I do have a few questions for this whole process:
1. How to un-root?
2. I am now using the JME rom. I saw 2 APNs in the mobile network settings. 1 for AT&T activation used to activate the SIM with voice plan, another for ATT Broadband used by data-only SIM. The activation APN for SIM with voice keep coming back even after I deleted it. And it also seems it takes a lit too long in 'checking SIM' during booting. Does anyone know how to remove the activation APN?
I am afraid I can not answer your question however I do have a question for you. I am still running stock firmware and plan to upgrade soon. However would like to be able to get to same stock version I have now if possible. Can you list the baseband/firmware of the stock AT&T you obtained and rolled back to?

I used the Roto's stock ATT rom. The firmware version is xxxxUCJK1. I believe that is the right stock firmware version as I have also seem it been mentioned in various other websites.
Since you are still using the stock rom, it is good opportunity for you to back up everything:
Roto Backup - http://forum.xda-developers.com/showthread.php?t=850359
Thanks. That is the current version I am running. I will probably upgrade this week. I have already taken a Roto backup as well as used Titanium Backup. I also have screen shots of every screen I could bring up. I think I am all set; just need to pull the trigger and do it.

I was able to unroot with SuperOneClick, will now be flashing back to AT&T stock!
UPDATE 1 - Oops...Odin stays stuck at "SetupConnection", any tips on circumventing that? A search didn't find any fix for now :-(
UPDATE 2 - ok, started with ON+Volume down and Odin worked...BUT I get the AT&T splash screen and then it goes to the "recovery menu" (the one you get with ON+Volume Up")
The yellow lines read :
update media, please wait
update media, finished
# MANUAL MODE #
-- Appling Muti-CSC...
Installing Muti-CSC
Any way to get out of this mess ? Thanks !
UPDATE 3 - taking the SIM card out solved that, phew !
I flashed a wrong PDA file onto my cdma tab. Now my screen and backlights do not come on. I am still able to flash via Odin and also Heimdall. I have no idea as to what it is that is causing it.
I bought a T-mobile Tab
I was successful at:
Gaining Root Access
Flashing Clockwork Recovery
Now, every time I try to flash a rom with heimdall, it pushes all the updates to the tab, and it will get stuck on reboot.
I did a full factory reset (from samsung's recovery because apparently Clockwork got deleted), and it appears that the Euro rom is on the tab now because there is a phone app functioning, and it is stuck on only Edge data.
I have tried flashing almost all the GSM roms I could find on xda and I cannot get one of them to work sucessfully without locking up at the boot screen.
I do not care about the freakin phone capability I just want my 3G back. Can someone direct me to a simple... non-euro rom where I will be able to get my 3G working again becuase I am tired of ending up at the same darn place over and over again.
Have you tried Roto modem switcher? I don't use Tmobile but I thought that will allow you to switch between EDGE & 3G? Check out Dev forum.

i tried to connect with the network operator telling me that there is no problem with connection the problem is in the phone
any one can help me to fix this problem
Not in this topic I had written. But as I wrote something that could help it - maybe you should do factory reset ??
Region?
Did you obtain the working handset from the same nation as the handset with the problem?
Which nation are you trying to connect from?

I'm having the same issue but, for what it seems, it should be a config file... try posting the question in the Ace-i's forum.. at least it's the same family model as the Ace-M (which I also own).
Maybe it has to do with CSC...

already post question but no one answered it
In case anyone is facing this issue, I resolved it by flashing an S5830C's NVRAM, it has to do with the NVRAM which contains the actual baseband (800/900/1800/1900 etc..), you can find it in the Bootloader package:

Hi, the file is in 7z because it's a whole firmware, but to fix the 3g issue in a S5830C/M you must use ONLY the Bootloader part of the flash, you'll know it because the tar part corresponding to it, has a file inside named like "HEDGE_NVRAM" and something else :silly: make sure to use the PIT corresponding to the cooperve, which you can find in the tutorial by @feetsonfire about how to recover from a brick.
Try first with Odin V3 1.84 if it doesn't work, try it with Odin V3 3.07.
There is no need for doing anything else! No recovery nor anything else related to it, just what I exposed in my post!

No need... Unless you want to do a factory reset lol :cyclops:
I had an issue with Alliance rom. It went from wifi to 4g and I lost the prl and other stuff (said unknown). I only had wifi.
I was able to Odin back to stock. It took like three times as it would not move past the activation screen.
Now, on stock, I flashed TWRP recovering using ODIN, then used the CF root from Odin also. Phone restarted and while I have the 4g logo, I have no phone and the information is missing again (PRL). I do get wifi.
I just used Odin to reflash stock and it is still doing it. I also used the imei tool to restore what I had backed up (EFS). Can anyone help? What is going wrong?
Edit: Phone restarted with root BUT now I cannot make calls (it says roaming) and I am missing the prl and other things again. HOWEVER, I can use wifi, and 4g and no texting also.
If anyone has a clue I'd like to know, thanks.

I actually could not find the stock modem. I DID solve it.
1.) Odin back to stock. It will freeze on the activation screen.
2.) Remove sim card after shutting down.
3.) It will get past that and connect with wifi.
4.) THEN clock on roaming to turn it on with sim in.
5.) Phone will then contact US Cellular to "activate and program." It will finish after a few minutes.
6.) Restart and enjoy
In case this happens to anyone else. Thanks for the help (lol). I've had a Droid Eris, HTC DNA, and a Droid Bionic.
