I picked up a used AT&T S3 here in NY because I just installed an Alpine ICS-X7HD in my car. The S3 had the latest NJ1 installed. I was able to root the phone OK. My research has lead me to believe that I won't be able to get any version of Drive Link running on Android 4.4 without FCing when connecting to the Alpine Unit. Research also seems to suggest that I can't go back to the LK3 version either due to boot loader changes made from Samsung and AT&T with the 4.3 update. So I'm looking for advice from the forum experts on what I can do, if anything to get the phone downgraded to a Jelly Bean firmware. I am hoping to hear from someone who has been able to do this before. Can I go from 4.4.2 to 4.3? If so does Drive link still work for you?
I am comfortable using Odin and adb. Let me know if you need any other specific information.
The solution was so incredibly simple. I flashed the AT&T+UCMG2.ZIP through TWRP and rebooted. Now I am on 4.1.2. Drive Link working! So To Recap...I went from 4.4.2 NJ1 back to 4.1.2 and stayed on NJ1 baseband.

How did you root on Nj1??!
To get to jelly bean, you do the hack like method above by flashing a zip in TWRP or Clockwork mod or boot a custom rom based off 4.1.x. Once you are on 4.3 or 4.4, there is no going back to a previous version, attempts result in bricking.

About a year and a half ago, I gave my father my T999L after I upgraded the phone. Since then it appears a 4.3 update has been released and in order to use his Galaxy Gear watch that he wanted for his birthday, he needs to upgrade. He wants to stick with a stock (or stock based) ROM and I need to get it taken care of for him today. When I had the phone, I was running Dandroid. Because I rooted, installed custom recovery, etc. it reads as modified software and will not receive the OTA even though I flashed returned it to stock before I gave it to him.
Any help would be great - apparently the 4.1.2 bootloader won't work with the 4.3 ROMs? Anyone have a link to something I can just use ODIN to flash and get it all done in one step? I assume the link here can do it? Hopefully...

Thanks in advance.
EDIT : Never mind, we're good. I got it figured out
I am not very much familiar with all intricacies of Android system but i have played around rooting and putting customer firmwares on few devices.
I have AT&T Galaxy S3 with following detals:
Baseband: I747UCUEMJB
Version: 4.3
I had the device rooted in the past but recently un-rooted it and reset the flash counter as well and did factory reset. Did all that since i wanted to use ISIS and couldn't make it work on a rooted S3. Seems it used to work before till they updated ISIS app to patch it.
Now AT&T got 4.4 update and my phone detects it, downloads it but while installing fails at 32%. I have seen many threads where people faced similar issues due to their phones being rooted. Seems something on my phone didn't reset to default.
I found one post which mentions that i can download UCUEMJB_to_UCUFNE4_Firmware_update.zip and load it to phone using TWRP. As i understand, this will update the baseband but android version still remains at 4.3 (?). Is that the path i should be looking for or i am shooting in wrong direction? I want to stay on default firmware since i like to use ISIS till they keep running those cashback promos
Would appreciate some feedback.
Download MJB firmware (thread in General) and flash with Odin. You can stop there or try the ota again.

Thanks for the reply.
Just to confirm so that i don't mess up, i will apply the following(is modem same as firmware?) and then try OTA.
I747UCUEMJB: modem_CWM_I747UCUEMJB.zip
No. The modem is only one part of the firmware. Firmware includes bootloaders, kernel, system, modem and more.
I'm running 4.2.2 on my 10.1 and it is rooted.
It was done long ago and I really do not need the device being rooted anymore.
Not sure how to unroot it so I can upgrade to 4.42.
It might have been posted but I couldn't find it.
Help appreciated.

Beware that some of us believe that upgrading to 4.4.2 via OTA or Kies or installing Stock 4.4.2 as they come is unsafe!!!
New stock 4.4.2 comes with new bootloaders!!
So for us the safest way to upgrade is use one of the many Rom develop in our forrum. Yes I understand many think the opposite,safest is to stick with Samsung Stock as it come from factory. It is up to you.
A few had claim that after you go back to 4.2.2 Official Stock, their programing counter had clear and they in fact go OTA or Kies to upgrade to 4.4.2. Personally I do not know. I do not use Kies.
But here is an example of such Claim:
Samsung Galaxy Tab 3 > Galaxy Tab 3 General > KitKat Update official for GT-P5210 available => http://forum.xda-developers.com/galaxy-tab-3/general/kitkat-update-official-gt-p5210-t2871073
Good luck with your upgrade, I hope nothing happens with those new bootloaders in the future. Who knows maybe you will not be able to clear your counter again! I do not know I am just kidding.
Thanks, that worked, now I am on 4.4.2.
Just a crazy question, what if I want to go back to 4.2.2, can it be done?

You have not said what type of TAB3 10 you have. 3G, wifi or 4G. Nor said what procedure you follow. Ota, Kies or one of the roms develop here.
I do not know if installing 4.4.2 with OTA or Kies can prevent you to go back.
In my case I use 4.4.2 Pimpdroid 3Beta. I found it smooth and nice. But I got upset with 4.4.2 limitations and went back to 4.2.2 with stock 4.2.2. Without any problems.

I have 10.1 tab 3 wifi only, i was rooted in 4.2.2, installed a stock rom of 4.2.2 via odin, after i received an autoupdate via OTA to 4.4.2
Hello folks.
I am new here and am not sure how it all works so please forgive me if I have posted in the wrong spot or am asking something that has been beaten to death already.
I have a AT&T GS3 I747 . I received the OTA 4.4.2 update for it and used it just fine. One day i got a bug in me to root and flash it. I rooted it, installed CWM 6.0.47 or something like that and installed Gummy Rom running kitKat 4.4.4.
I would love to return my phone to 4.4.2 with or without root. Is this possible? I have read and read to NOT take these backwards after JB 4.3
I have looked until I was blue in the face for a rom to use and am drawing blanks. I probably found one once and didnt know it. I can flash and all that and do it regularly, I just don't understand all the fancy lingo so I probably overlooked what I am looking for.
So bottom line, is it poissible for me to go back to stock 4.4.2? I would love a stock rom minus all the at&t bloatware since I will be unlocking it to straight talk.
Thanks for your time and once again, my apologies for dragging this all up again if it has been covered already.
First thing to do is update that custom recovery, or at least confirm you're on the latest version. I think that version you quoted is a little dated, and that has potential to cause you some problems flashing ROMs. An easy way to get and install the latest recovery is an app called Flashify.
Next have a look around the development section: http://forum.xda-developers.com/galaxy-s3-att/development
You'll find some debloated TW ROMs for that stock feel without the AT&T & Samsung junk along with plenty of other good ROMs to choose from.
It's wise of you to be cautious @DjPorkchop.
You are correct, you should never again downgrade your bootloader and modem, also called firmware and baseband. The very latest AT&T OTA updated bootloader and modem to NJ1, it is part of the 4.4.2 stock install. The OTA before that loaded NE4 bootloader and modem, they were also in a 4.4.2 stock rom, but you can not downgrade to them if you are on NJ1. AT&T has not issued an newer bootloader and modem than NJ1.
The good news is that the custom ROMs do not flash bootloaders and modems. You are safe to install even a 4.4.2 custom ROM on NJ1 firmware for this reason. There are stock system dumps available, with these you have to use caution because the bootloader and modem may be present, not always however. Talkingmonkeys has a TouchWiz based 4.4.2 ROM, TMS3KK, that is available in two versions, the second is heavily debloated. I am using the 4.3 Android version and will be soon updating to the heavily debloated 4.4.2 version. (He's still doing some minor theme tweaking on the newer version.)
How do I tell if I am on NJ1 or NE4? As I recall, I got the 4.4.2 update and all but immidiatly after had my phone shut off. I don't recall ever getting a 2nd update to 4.4.2 as long as my phone was active. I have been known to be wrong before though.
And I thank you much for the info. I will go check that thread out as soon as possible.

There is a "Samsung Info" app in the PlayStore that will give you the info.
Or, in a terminal emulator you could enter:
Code:
getprop ro. bootloader
and
Code:
getprop | grep version.baseband
Thanks for letting me in on that app. It shows me on NE4.
So off I go to figure out what I am going to do to this phone. I am going to visit that thread you mentioned to me and see if I can make heads or tails of it and get a rom for this phone. I ike Gummy rom but it is a bit to much for me. I really want to get back to as close to stock as I can get safely without bricking my phone.

Ok so I revisited that page again and I can't make heads or tails of what to do. I know for certain I am on NE4. That is all I know. Any suggestions from that page to get me as close to stock as I can? I see there is a stock theme revert as well on that page.
Sorry to be such a pain. I am one of those guys that figured out how to root and flash and never should have.

That room comes with a dark theme. The revert is not needed unless you want the lighter colored stock theme. I use the dark because, supposedly, a dark setup is a little easier on battery drain compared to light or white themes. I didn't install the extra battery mod, he had enough options built into the rom to suit me.
Sorry for the post, but I've looked elsewhere and searched can't seem to find the best, fastest, and easiest way to accomplish this.
1. I have an AT&T GN8.0 (SGH-i467) on 4.1.2. Build CAMF2. I'd like to upgrade to 4.4.2 The device is rooted, with locked bootloader and stock recovery. I also have an AT&T Pay-as-you-go SIM installed.
2. I'd like to end up on 4.4.2 rooted. I have never been offered the 4.4.2 upgrade on my device and I'm not sure if it's because I have a PAYG sim or it's cause I'm rooted.
3. I'm not afraid of Odin, download mode, etc., so if anyone can help me figure out the best way to get myself upgraded, I'd appreciate it. If you want to point out some posts, threads, etc., that can help, that would be great too, but I've scanned all of those and it all just gels together to where I'm not sure what's what anymore.
Thanks.
Don't try to update via OTA with a rooted ROM as it may cause a softbrick. I recommend unrooting and trying to update or flashing a stock ROM from sammobile.com and then try to update to KK.

Thanks, that make sense.
Going back to stock shouldn't be a problem, but any thought to if I can update to 4.4.2 with a PAYG SIM? If not, is there a flashable file and method that you can point me to?
It has been my experience with various phones that OTA updates should work regardless of whether a sim is or is not inserted.
