I have a completely stock S3 from AT&T never rooted. I recently took the OTA update to NJ1 now. Am I now still able to root and install custom recovery to the phone? Or my bootloader is now locked down with this new OTA update?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] melvinaury:
You only need Odin, a custom recovery and supersu.

First install the recovery in download mode, then when rebooting enter recovery and flash supersu. You can't let the phone boot after the recovery installation or the stock recovery will be installed.

Thanks man. It turns out well.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] MetalHead66:
So after reading this entire thread I'm assuming it is safe to just flash nj1 bootloader and modem. I'm currently on ne4, 11-06 Carbon and 9-17LK. I'm wanting to update modem because every LP Rom I try I end up losing LTE so hopefully this will solve that problem.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
Yep go ahead and flash it bro! I have 2 d2att's one was on mjb & other on on ne4, I updated the mjb in steps, to ne4 then nj1(wife's phone) Mine was on ne4 so I just flashed nj1 in (TWRP 2.8.3.0) and reaped the rewards! Only thing I can tell is less dropped calls & HELL of a better signal! So go for it just boot recovery & flash, reboot, no wipes needed!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] MetalHead66:
Ok thanks for the quick reply. I'm always hesitant to flash things where there's a possibility of a brick. I own my phone and this is my only phone. Except for my OLD Nokia e63 and would dread using that. Will give a go shortly and see how it goes!

After flashing NJ1 bootloader and modem and keeping NE4 rom my wofo doesn't work. Anyone experiencing this same thing?

Understand,lol! I'm the same way & I've been a crack flasher for awhile now, since my Tmo exhibit 2 4g. Still a bit hesitant as well when it comes to stiff like this, good luck & happy flashing bro!!

If its stock ne4 ROM, you need to download the stock rooted nj1 ROM & you'll be good to go

Everything working fine here. Gonna try flashing Cyanide again after my battery finishes charging and see if I can get LTE to stick.

This is my first Android phone and had it about a year and 8 months now. Had it rooted within a month after purchase and realized I will never own anything unless its Android. Can't wait for the S6!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] OKAstro:
Some questions:

1. Can't go back to NE4 bootloader after flashing NJ1 right?

2. I can still flash Enewman17's latest S3Rx 4.0 TouchWiz 4.4.2 UCUFNE4 (11-9-14) if I'm on the NJ1 bootloader right?

3. What improvements have you noticed in NJ1?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] MetalHead66:
Not sure about 1 and 2 but to answer number 3 I have noticed a pretty decent speed increase in my wifi but data seems only slightly better. But both are more consistent for me. And also switching between the two connections is faster. Before the nj1 if I turned wifi off it took 5-10 seconds before my data kicked in. Its instantaneous now.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bbayer:
I'm on Likewise 4.1 with the NE4 set up and updated the bootloader and modem to NJ1 with no problems! Signal strength has increased for me. Awesome work from Enewman.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] melvinaury:
1. No can't downgrade bootloaders.

2. Yes you can install any rom, based on NE4 or later. Made sure to not install bootloader.

3. Was already answer..
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Rapscallion16:
I'm trying to update my brother's GS3 from stock rooted NE4 to NJ1 without wiping anything. Can this be done by just flashing the system.img/boot.img and the bootloader/modem zips in TWRP? I searched the whole thread, but couldn't find a definitive answer.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] whodisname:
Just flash the bootloader and modem zip. Done.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] melvinaury:
The other option that you have is to unroot, install stock recovery and upgrade. Then install custom recovery and supersu. You don't lose any data..
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] OKAstro:
Am I correct that if we're already on S3Rx 4.0 TouchWiz 4.4.2 UCUFNE4 we can just flash the NJ1 modem/bootloader? Or do we need to reflash the ROM again after flashing the bootloader?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
Yes, you can just flash the bootloader/modem combo without flashing the ROM.

Question on the NJ1 modem

Is there a way to ODIN the NJ1 modem while still being on the NE4 bootloader? I want the better signal the NJ1 modem has, but would like to stay on NE4 so towelroot continues to work. Thanks in advance!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] melvinaury:
I'm not sure about that. I read bootloader and modem need to match to be able to had wifi working. If not you need KT kernel for the wifi to work.:rolleyes:
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Sealy64:
Crackly sound

About July 2014, my S3-i747 developed a problem that sounds like yours. At my home, I could not maintain a call for more than about three minutes. The call was clear for a few minutes, then a noisy/crackly sound for 1-2 seconds, then the call dropped. It happened only at my home. I have other cell phone lines, with the same carrier, and they hold calls well, even at my home. The problem started shortly after AT&T pushed an OTA update, which made me suspicious, but I could not roll back the firmware to test my suspicion.

Does this sound like your problem? Back when the problem first started, I searched the Internet quite a bit but found no one describing a similar problem. I finally gave up and got a new phone, but if the NJ1 modem fixes the problem, I'd like to have the S3 as a backup. To test I will have to get a micro SIM card, because my other, active lines use nano-SIMs.

I would appreciate your feedback on whether this sounds like the same problem.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] StoneyJSG:
Oh okay. Ah bummer, so it's not like the At&t Galaxy S4 where you can have different bootloaders and modems.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] melvinaury:
Fie me it made a big difference in call quality and in Wifi signal..
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mwrobe1:
Sealy64...I never timed it...besides that, my issues were very similar. My work location was and is a low signal area and has experienced what you and I described plus having some calls go right to VM. As of this posting...I have still NOT had a dropped or "crackly" call FYI.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
Nope bootloader & modem must match!?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Sealy64:
Crackly sound and dropped calls better but still not usable

MWROBE1 - Thanks for the follow-up. This evening I was able to borrow a Cricket (ATT-owned discount pre-paid; runs on AT&T network) micro SIM and test my S3-i747 with it. I still experienced the crackle every few minutes. Calls sometimes got through the crackle without dropping, but one call dropped after 3-4 "crackles" (about 10-12 minutes total) and the next call dropped on the first or second "crackle" (3-5 minutes total). In summary I'd say the ability to maintain a call was improved, but only marginally. I guess it's time to give up on my S3. (I would very much like to try another S3-i747, in exactly the same location, with the same firmware and same everything else, but I don't see a realistic way to make that happen.) Thanks again.

I continue to be amazed that, with the exception of mwrobe1's report of the crackly noise, I have not found any other reports, on the web, of similar symptoms. If anyone else reads this and has had similar experience, I would be interested in hearing it. I also would be interested to know whether the symptoms started in the July/August timeframe, roughly coincident with that AT&T OTA push. I had the phone for nearly two years, crackle-free, until about July/August 2014.

Okay thanks. I was thinking it was like the S4 so I could get the NJ1 modem while being on NE4, but it seems a no go.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] grndnl:
Thank you very much, that was successful! Could give me more details about what's special with the file you uploaded?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mwrobe1:
I'm sorry to hear that...don't want to thread drift but...the only other 2 things I have done is turned off Call Noise Reduction (Phone App>Call Settings>Noise Reduction>uncheck) and with the back cover and battery removed...I made sure all visible screws were tightened (I know I did this last year.)

This is assuming factory reset attempts have been done already (even after flashing a new ROM)

One other thing...have you tried having AT&T replace that micro-SIM for you? They can go bad.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Sealy64:
Crackly sound and dropped calls - cont'd

I did multiple factory resets and tried things like turning off Noise Reduction, to no avail. At the time the problem developed, I had other AT&T phones with micro-SIMs; although I did not get a new SIM from AT&T, I did try the others I had, also to no avail. I now have switched to Cricket, which means a new SIM, but that did not help, either.

I could try checking the tightness of the screws, as you suggest, but I am skeptical of that being the issue, because the problem only occurs at my home (even though all my other four lines work fine there), and I would expect something like a loose screw to cause problems everywhere, not just in one location.

When going from an AOSP rom back to STOCK rom it is highly recommended doing a complete clean flash install. I personally like using TWRP to wipe dalvick cache, system, data, cache, internal storage, and follow it up by formatting data. Good luck on a totally fresh install !

IS there a way i can go back to NE4???
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
Only way I know to go backwards or downgrade bootloader & modem is to flash the stock tar via odin. However I doubt very seriously that NJ1 has anything to do with your camera not working, bootloader & modem have nothing to do with the camera!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] melvinaury:
Yes you only need to install the NE4 stock zip that was posted. The zip file don't include bootloader and modem.

Remember that newer bootloader need to match modem and are backward compatible with previous Roms.

On the general section you can find the NE4 zip.

Good luck.

Yes, if you are on NE4 boot loader and don't want to change anything Elsa,grab the nj1 boot loader/modem.zip and flash in recovery. Reboot (no wipe required at all) and then delete the file. I just say delete the file because you will never need to use it again.

UCUFNJ1 service menu

Although there are modem improvements, some service menus might have been disables on UCUFNJ1 . My 2yr contract just finished up with AT&T and I got the unlock code from them; which didn't work. Hence I tried to get into service mode screens to see if there is anything I can do to get it to work, and learned that some of the menus that used to work seem to have been removed.

Update:

I was able to unlock while on this ROM (which has root) -woof it was my 5th try.

I tried the following codes:

Does not work: *7465625*638*#

Does not work: *#197328640#

Works: *#06#

Somewhat: *#0011# : goes to the telemetry data in ServiceMode, but in there menu->back->menu->Key Input 1 goes back to the same screen.

Does not work: *2767*3855# : gives a Connection problem or invalid MMI code error.

Works: *#197328640# , in there follow the Perso SHA256 ON method that is discussed on XDA and other sites, and upon reboot the phone accepted the unlock code that AT&T provided and unlocked successfully. Note that it took a little bit for the dialer app to accept *#197328640#; aka it just sat there for 20-30 sec with no prompts and I even entered the code a second time while waiting.

Hello all

I would appreciate if you can show me some direction to help achieve desired result.

I rooted my AT&T galaxy S3 with KOT49H.I747UCUFNJ1 build, used TWRP recovery and flashed couple ROMs, did not like them, so restored my TWRP backup.

Some of the apps now force close and I was hoping to go back to rooted Stock build.

My question is, the rooted stock ROM on this thread is the NE4 build and I believe I should not flash that as it would brick my phone since I am on NJ1. Is that right? If yes, then how to go back to stock NJ1 with a reasonable safe chance? There is another thread by enenwman17 which has the rooted stock NJ1. Is that the one I am looking for? (Dumb question, right)

Thank you in advance.

The above link is courtesy 'ENEWMAN17' and it worked flawlessly during my experience. If I were you I'd get the latest TWRP recovery and do a complete advanced wipe of: Dalvik Cache, System, Cache, Data, Internal Storage, followed up by Format Data. It's a large file, so be patient during installation and boot up. For peace of mind do not use any previous 'TB' or 'TWRP' backups when going back to full stock rom. Good luck!

Then did update with UCUFNJ1 Root and know it has Wifi and network with IMIE . But know its not reading sim card? Its not the card because I tried in different phone and made a call . :crying:
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
Just to be clear: You are on the i747 (AT&T) and not the i747M (Canadian variant), correct?

When going from MJB to NJ1 did you go sequentially from MJB to NE4 and finally to NJ1?

Have you checked to make sure both your bootloader and modem are correctly at NJ1?

You can check with the "Samsung Info" app from the play store. Or, you can use a terminal emulator and these commands >>

getprop ro.bootloader

getprop | grep version.baseband

Have you checked your APN settings?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] stealitall:
You can see its all right but since 4.4.2 sim card don't read. But if I lower it to 4.3 it reads but no sound or wifi or network???
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
Your screenshots show NJ1 like you mentioned. From what you say, you went back to 4.3 bootloader and modem at some point after the update to NJ1 as a test. Going backwards like that could cause a hard brick from which you can not recover --- be careful.

Does the IMEI in the screenshot match the one behind the battery?

First, check your APNs and see if they are correct. Correct them if needed. Maybe this will fix all.

If the APNs are correct, and the screenshot is of your current setup, I would probably reflash the NJ1 bootloader and modem.

If you are now on MJB bootloader and modem, I would think you need to first flash NE4 and then NJ1. BUT, DO NOT do so until you have othes confirm this is the correct thing to do. Going backwards was risky, skipping versions is risky.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] stealitall:
Yea IMIE matches . But Cant get to APNS in NJ1 it doesn't read sim chip. But on MJB - NE4 it reads the sim chip but don't have network:confused: I re-flashed Modems for NJ1 but no fix
