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 #

Installing Muti-CSC
Any way to get out of this mess ? Thanks !
UPDATE 3 - taking the SIM card out solved that, phew !
I picked up an AT&T (US) Atrix off craigslist that had an issue where it would show 'Sim Unlock' everytime you tried to use a SIM card, even one from AT&T. I purchased a SIM unlock code, but when I entered it, it would immediately report the request was unsuccessful (like it wasn't really sending out the request). I tried three different SIM cards, two from T-Mobile and one from AT&T and always the same issue. The previous owner of the phone had also purchased an unlock code (which matched the one I purchased), and tried to enter it over 20 times.
After digging through all the forum posts, I found two people that had the same scenario and were able to finally resolve it. In both cases, the person was able to fix the "unlockable" phone by flashing the radio (usually through at least two different versions).
The phone I have had standard OTA 2.3.4 (4.5.91) with radio N_01.77.30P. It works fine on WIFI, nothing else is wrong with the phone. It was not rooted nor was it boot unlocked.
Here's what I did to fix it...
I unlocked the boot loader, installed CWM, and rooted it (all stuff from the standard guide in this forum). I then did the following sequence:
1) wipe cache and flashed radio N_01.100.00R_gb_retail_22sep2011.zip
- tried the unlock code, failed immediately
2) wipe cache and flashed N_01.77.33P_can_bell.zip
- tried unlock code and it worked!
3) wipe cache and flashed N_01.77.36P_usa_att_.zip
- just wanted the latest radio
(Radio zips are all available in the forum post labeled 'Atrix RADIOS', http://forum.xda-developers.com/showthread.php?t=1339047)
Now I am able to use both T-Mobile and AT&T SIM cards without any unlock messages. Phone works perfect!
Also, I think this shows that there is no hard lock on the Atrix. The previous owner entered the unlock code at least 20 times, and I did it probably 10 times, and yet after this process, I was still able to unlock it (with that same code).
Thanks to those who posted their working scenarios in the sea of postings on failures. I would have never resolved this without those nuggets!
P.S. I think you could even fix this issue without boot unlocking/rooting by just using SBF radio flashes, but I wanted to use CWM instead.
Although I never had the problem you experienced, I am glad you posted this. More people need to post how they solved it too. Good job.
MAN, THANK YOU VERY MUCH!!
I OWE YOU MY LIFE!!
Six months with a unlockable atrix ended yesterday!!!
These steps truly work!
thanks again!

The problem is that I have been unable to find these radios anywhere. Every link I have found is broken, as people are generally interested in "the latest and greatest" radio. Does anybody have access to the radios listed above? Especially the N_01.77.33P_can_bell.zip Thanks in advance for any help!
Wow
I just wanted to say thanks for your post I've been going crazy with this whole unlocking situation and your method fixed it!!
cant find the radio... link broken
N_01.77.33P_can_bell
cant find the radio... link broken
Awesome solution
Thanx so much for this solution man. You are a life saver. Hats-off for figuring it out that it will be solved by flashing a radio file. I wonder how you ever thought of that. Brilliant.
Thanks.!
Thanks.
I working excelent.!
Ok, I'm going to try to make a long story short, i hope that i've posted in the correct forum, I've been scouring this forum and others but nothing I've found has quite fixed my issue.
Got my S4 locked to Bell in Canada. Heard it was really easy to unlock [service menu *#0011# method] but once I got to Indonesia [for travel] expecting to be able to use my phone I found that the service menu was no longer available. Ok, no problem, there must be other ways;
I ended up paying for an unlock code from a site, it didn't work. In fact, immediately after I press 'unlock' it would say 'network unlock unsuccessful'.
I thought they gave me a faulty code but when the code I bought FROM Bell was the exact same one, and had the exact same problem I figured it was likely 'region locked'
I ended up flashing a stock rom with odin, one from a weird unlocking site, and eventually I got it working. The only problem was that whenever I'd go into screen lock I'd lose reception and have to airplane mode on and off to get it again.
After Indonesia I went to Turkey, was unable to connect at all with one of their service providers, but had no problems with Vodafone. I think this may have been a side effect of regionlock away app, I needed to use that as well.
Once I got back to Canada I went custom recovery with cwm and flashed Cyanogenmod. This was fine, no reception problems, 10.2 - 11 was all good.
NOW I am in Poland, and getting the same problem I had in the first place. Whatever Cyanogenmod did, re-locked my device, in some way, I'm guessing.
I'm now rooted, with TWP recovery, running Android 4.4.4 Dave GPE rom, and would REALLY like to be able to use my Polish sim card with this fantastic setup. Chainfire's regionlock away app does not work, gives me a CSC error message. My phone now says it's an i9505 instead of i337m
Anything I have overlooked? Any way I can get this fully unlocked and working the way I want it to?
*NOTE* I can't access *#0011# service menu, even though I flashed [i think] stock dialer.
You are not in the correct section
You need to be in this section.
http://forum.xda-developers.com/galaxy-s4-att/general
I can help you a little though. If the unlocking methodes fail, then it's usually because you don't have an older modem. You need to look for the modem you should flash in order for it to work. Afterwards you can flash the modem again you are on now. If you can't find it, just flash an old modem and try.
I find it hard to believe that Cyanogenmod could have caused this though.
Cool, that will be my next phase of attack. I appreciate the redirect and thoughts (Y)
Before you judge me by saying how i'm posting something thats done before, it hasn't, I've searched everywhere no methods work
Please, someone help me I've been at this for 4 days now and maybe just 15 hours of sleep :crying:.
The phone I have right now is the SGH-i337m Galaxy s4 running NC1 with MDJ modem (Kitkat 4.4.2) Does not detect sim, it says "No sim available".
I'm not exactly sure if the phone is from Bell but the phone use to be running fine on my old rogers sim card until I updated to their new ShareTap Sim.
With the ShareTap Sim the phone doesn't detect my sim anymore. So I tried my Share Tap Sim in another unlocked phone (Galaxy note 3) it worked fine.
Then I tried a Virgin mobile sim card on the S4 and it detected it and worked fine also. So then I tried to unlock it by flashing it with many different methods:
1. I tried flashing a older version of Bell 4.2.2 but it bricked my phone ( I already unbricked it back to 4.4.2)
2. I tried flashing the MDJ modem but it doesn't show the hidden menu.
3. I tried flashing ATT modem to try it but that also bricked my phone.
4. I tried to use the AWS tutorial shown here
5. I tried the regionlock away tutorial here in the third method (RegionlockAway doesnt do anything to my phone)
6. I pulled the modem.bin from the TAR file from sammobile of Bell's 4.2.2. But it still doesn't show the hidden menu! It's the MDJ modem but it still doesn't work!
I'm not sure whats wrong with my phone. When I put the Virgin mobile sim card in there it only shows Telus, EXT and Virgin Sim networks available not the whole spectrum which is what is supposed to happen with the 337_aws.qcn file from the AWS tutorial. Then when I flash MDJ modem from bell or the one from this dropbox link: https://www.dropbox.com/s/2m3id2cx4l...37MVLUAMDJ.zip
It still doesn't show my secret menu.
The secret menu I'm trying to access is the *#0011# but if that didn't work I also tried the *#9090# It still doesn't show the secret menu. So what do I do now? Please Help!
Thanks for reading!
Sorry to hear that, but you are in the same situation i was, the phone was probably sim-unlocked by Box Software, like Octopus or Z3X Boxes as i did, the phone won't recognize some sim cards by unknown reasons, there is no fix avaliable for this as i changed imei, tried different NVM from other phone & even replacing sim card reader. i finally sold it & got myself a i337m unlocked via code.
Edit:
forgot to mention, My SIM stopped being recognized when i upgraded it to a newer LTE version
Kind regards.
Have you tried stock NC1 with the included modem? If the device is unlocked, you might have better success with SIM recognition. In my case, my device was not unlocked, so I Odin flashed stock Telus MDJ, then rooted with CF-Auto-Root, unlocked with RegionlockAway (KNOX tripped), and applied the AWS Mod.
Then I flashed stock NC1 with the incl. modem (root gone), and managed to get Rogers LTE and Wind H+ on the Telus device. From there, I OTA updated, and rooted with CF-Auto-Root, flashed TWRP, and worked my way to 5.0.1. Trust me I know how frustrating this can be, but thanks to this forum, there was a solution. Here's what worked for me (link). Good luck.
Good evening friends, I have a question about a problem that I have not been able to solve. My S4 version 9505 is free from factory and so it has been for 10 months (I bought it used and that's what they told me) and suddenly in a normal restart it gave me a screen before the launcher that says Unblock or continue ... after that It says that I have a simcard with network blocking. Use Lineage 14.1 and go back to lollipop 5.0.1 stock to see if that solved it but it was not like that. I have imei intact but it is blocked by network.
i would be grateful to who can help me
Thank you
You can try to unlock it by flashing a 4.2.2 mode, root, run regionlockaway, flash stock 5.01 ROM, and see if the phone is network unlocked.

Hello
Your phone is not locked, the SIM card is. Have you set up a pin for the SIM card and forgotten?.....Try another SIM card in the phone to check.
The message that appears on the original post is the same screen I received with my locked sgh-i337m before I unlocked it using regionlockaway.

imei null when flashing modem I9505_XXUAME2_MODEM.tar
I had to flash a stock ROM again and the imei was recovered, but I still have network blocking
The IMEI goes null because you are flashing a 4.2.2 modem onto a phone with a 5.01 bootloader and flashing the latest modem will restore the imei.
If you followed the steps I outlined and the phone is still network locked, you will need to buy and unlock code.
I'm sorry I had not been able to answer for days.
I could unlock the phone as follows: Install via ODIN I9505XXSHQB1_I9505OLBHOH1_I9505XXSHQB1_HOME.tar then install the modem: I9505DVUAMD8_MODEM.tar, then root, and use Galaxy Unlock app.
I thank all those who helped me here and took the trouble to answer my post.
