In the past it was sometimes necessary to reflash the same ROM to have a successful boot. I would suggest trying that first.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] yoonus:
No Luck. I tried flashing the old ROM I ran (Android 4.1.2). It flashed successfully but Wifi was disabled. Then I flash stock recovery, did a factory wipe and reflashed it. This time, it succeeded with Wifi.

Back to zip in OP. I flashed 2 times. Still stuck in ATT logo. I am going to try I747UCUFNE4_Stock_Rooted_Deodex_3-31-15.zip posted by OP in another thread or S3Rx_UCUFNE4_AROMA_11-9-14.zip ROM.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] yoonus:
None of the above images worked for me. Each of them got stuck on ATT logo

I got an ATT i747 on the newer OTA FNJ1, I've already hosed the bootloader once but I fixed it already by flashing the FNJ1 bootloader again. Do you know if it's possible to go backwards on the modem from fnj1 to ne4? Or am I locked in until someone figures out how to unlock that modem?

Hardbricked

I was running SlimKat 4.4.4 with BMS kernel on my d2att. I was on the CUEMJB Bootloader and Modem, so I thought that I can directly flash the rom. First, what I did was flash UCUEMJB_to_UCUFNE4_Firmware_update.zip. It flashed perfectly till the end. Then I flash the I747UCUFNE4_Stock_Rooted_Deodex_3-31-15.zip, which had an error that I had forgotten. It apparently is caused by my BMS kernel, so I went on and reinstall SlimKat 4.4.4 to remove the kernel. It flashed perfectly, but when I rebooted my phone, it did not power on. I was thinking, what's inside the UCUEMJB_to_UCUFNE4_Firmware_update.zip, are they the bootloaders and modem for CUFNE4 ? If so, is my phone dead like all the others who flashed 4.4.2 modem over 4.3 ? Please, I need my phone bad.

Did you do a full wipe before flashing the rooted NE4 ROM?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] yoonus:
As per suggestion from another thread http://xdaforums.com/showpost.php?p=61576118&postcount=1460, I formatted internal storage (Media) from recovery. Then I was able to flash ROM (S3Rx_UCUFNE4_AROMA_11-9-14.zip) from that thread.

Initially when I tried to install S3Rx, it hanged at ATT logo.

Another lesson learned is, I was having old CWM recovery and newer ROM's (Kitkat) need latest version. So update your reovery if you are coming from JB or other versions
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Alomia:
Yes. I wiped caches, system, and the data partitions in TWRP. But after I flashed the NE4 rom, it stopped midway and gave me an error (I forgot what it is). So I wiped again, rebooted, (BMS is still on my loading screen), logged on at slimkat rom, rebooted again to reinstall slimkat to delete BMS kernel, succeeded deleting BMS, and bricking the phone after rebooting again.

You may have to use a jtag repair service if you want get the debrick images to boot your phone.

I just want to make sure I do this right as it has been a while since i flashed something on my phone, currently I'm running cyanogenmod 11 milestone 11, my bootloader and modem is I747UCUEMJB version, I'm rooted and have clockworkmod 6.0.4.7 installed, so based on that information i just need to follow steps 2 thru 4? Really what I'm trying to do is unlock the phone but as far as I know that's only possible under a stock rom, If I got this right or if there's a easier way to unlock please let me know, thanks
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
The free sim/carrier unlock only works when on the 4.1.1 modem. Unfortunately you can not downgrade your bootloader once you have updated to 4.3 or beyond. If you are wanting to use a purchased unlock code or one from your carrier, then going back to the stock ROM based on your current bootloader or this one should be sufficient. You probably do not need to do step 4, returning to stock recovery. But, since you only get 5 tries with AT&Ts unlock code, I would go back to stock recovery if the first attempt while still on a custom recovery was unsuccessful.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] floatingtrees:
thanks for your help it installed correctly and thanks to the op for providing files and instructions, now I need to find a tmobile sim
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] aristocrates:
I am currently rooted with stock rom 4.1.1, with DLK bootloader and modem. Can I confirm that this process will work with my phone? My main concern is whether I will brick it when I flash the MJB bootloader / modem since I would still be on 4.1.1 and not anything 4.3+ if I just follow these steps to the letter. My recovery is TWRP 2.8.7, can I also confirm that all of these steps can be completed by just flashing the images in TWRP? Also can someone explain why one might need to follow step 4? Thanks.

Edit: so I flashed MJB and NE4 in that order as per the instructions (without changing my rom from stock rooted 4.1.1) and it successfully booted both times. Currently attempting to put a custom rom on it now.

Edit2: After flashing NE4, I flashed a cyanogenmod 12.1 nightly and it is working perfectly, the new modem / bootloader solved a problem where it wasn't recognizing my sim card.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
Glad to see it worked flawlessly for you. Now I know that to go from 4.1.1 to 4.3 it is not necessary for others to go through 4.1.2, it can be skipped. 4.1.2 had the MG2 bootloader and modem.

i followed this step. im using stock android 4.1.1 I747UCDLK3 before doing this step.

i use twrp 2.8.1.0 for flashing the mjb bootloader and modem without any problem and rebooted fine, then

i flash the NE4 firmware update and reboot, and still work ok, then i download and flash I747UCUFNE4_Stock_Rooted_3-31-15

without any error, after rebooting and wait more than 10mins, im still stock on at&t logo, can anyone help me?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jason2678:
Try wiping cache and dalvik in TWRP then reboot to your ROM. Give it a full 15 - 20 minutes. First boot can take a long time.

If that doesn't work try another clean flash. Wipe cache, dalvik, system, and data. After that format internal storage under wipe. Make sure you back up any important files stored on your internal SD before doing this and move the ROM you're going to flash to external SD because this will totally blank your phone's internal storage. After the wipes and format try flashing your ROM again.

Usually formatting internal storage in TWRP is enough to get TW to boot up, but not always. It you're still stuck on AT&T after this, track down Philz touch recovery and do a wipe and clean flash from it. Philz seems to do a little better job cleaning up the phone than TWRP.

Hi,

I'm on the MJB bootloader with Liquidsmooth rom 5.0 lollipop. I'm trying to update to official CM12.1 but that thread says i need to be on NJ1 bootloader.

My question here is can i just flash MJB to NE4 to NJ1 bootloader and then update to CM12.1 or should i flash the MJB to NE4 firmware and then update the bootloaders?. I guess firmware update is not needed but wanted to confirm before i mess with the phone.

And i believe i need to use the deodexed + root NE4 bootloader?

Thanks for your help in advance.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
Did you ever get updated? If you're on a custom CM based or AOSP ROM & MJB firmware then you don't have to flash a stock rom. This is how I updated (incrementally) from MJB. I was on CM11 M12 with MJB. All I had to do was flash NE4 bootloader & modem zip in recovery & reboot. Let the phone boot up & check your baseband in settings/about phone. It should be NE4. Then reboot into recovery & flash NJ1 bootloader & modem zip. Reboot & check again. Then you're good to go, you can flash all the latest LP roms & have no data issues. Just remember to flash bootloader & modem at the same time with enewman17's combo zips found on afh. Flash in the correct order (MJB to NE4 to NJ1) & never try to downgrade bootloader & or modem.

Newbie stuck with S3 issues

Hello all,

I have had my S3 for 3+ years SGH-I747 with AT&T. Last night I got a notice for OTA software update and I started it. I believe I was on 4.4.2 but can't be 100% sure.

After the software update, it would keep giving me "Unfortunately Settings has stopped, OK". I went ahead and did a Factory Data Wipe/Reset thinking it would fix the problem. Well, after the reboot, it asks for selecting Language and then again the Settings has stopped message pops up so I can't even configure the phone.

What are my options now? I downloaded Odin 3.09 just now. I have never used it before but am willing to try anything. Since I am on v4.4.2 most likely, I will need to reflash with this particular version, correct? The original instructions in the first post while excellent aren't enough for a newbie like me when I can't do anything with the phone stuck at the "select language" screen itself.

Any advice greatly appreciated. Thanks!!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
Did you try using the option to wipe/reset and cache a couple of times?

I recommend not flashing anything else until you confirm the bootloader on the phone. It is likely that the bootloader is now on KK but it's best to confirm this before flashing.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] agaurav:
Thanks much. I did try to wipe data/factory reset and wipe cache partition 3 times alternating each. No help. When the phone boots, it keeps saying that Settings has stopped. BTW, in the recovery screen it says: Android system recovery <3e> KOT49H.I747UCUFNJ2. If that gives any clue on what the phone is on currently?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
Are you sure it says NJ2 and not NJ1?

Did you want to run a stock or custom ROM?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] agaurav:
Hello - yes, I reconfirmed that it says NJ2. I don't quite care about rooted or custom ROM. Stock everything works for me. I just want a phone :) Don't want to buy a new phone at this point in time if I can avoid it. Thanks again!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
I asked about the number because mine is an i747m and is running the latest bootloader which is FOB1 and I see FOB1 in recovery.

The only way I know to restore the stock ROM is by installing a custom recovery and flashing the stock ROM.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] agaurav:
Thanks much. I am on AT&T (I747) and perhaps that is why difference in bootloader version? See - I am really new to this and am still confused to start the custom recovery and flash process. The link you sent is for UCUFNJ1. Would that work for my UCUFNJ2? Also, I am still searching but is there really an idiot's guide to recovery? Some of the terms in the first 2-3 pages of your link above doesn't mean much to me - how do I get started etc.?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] agaurav:
BTW - all this happened last night when AT&T pushed the following update:

https://www.att.com/esupport/article.jsp?sid=KB415621&cv=820

This is what did the phone in. So sad. I was without a phone all day today. Isn't there a simple way to just get a Stock ROM for the I747UCUFNJ1 perhaps that I get and use Odin to download to my AT&T Samsung GS3? Most other posts talk about custom recovery ((CWM or TWRP), wipe, recovery and more complex processes. Do I need all these?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] enewman17:
Sucks... I updated my s3 just fine. I'm uploading the rom right now. So if you have a custom recovery installed you can flash NJ2 again.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] agaurav:
Hello enewman17. I actually don't have anything (as far as I know). I am new to all this recovery process. The phone was just regular AT&T software etc. I will try to search online for what it means to have custom recovery installed. I am guessing that now I can't install it because it is chicken-n-egg problem. The phone boots to "Select Language" screen and doesn't proceed further due to Settings app not working.

Download Odin 3.0.7 http://xdaforums.com/attachment.php?attachmentid=1168421

Download TWRP. https://dl.twrp.me/d2att/twrp-2.8.7.0-d2att.img.tar.html

Power off phone... then HOLD volume down, power and home at the same time till you see download mode, then press volume up once more.

plug into computer, start odin

Check the box next to PDA, then load the d2att_twrp.tar in the pda slot

press start.

Once the process is finished the phone will reboot... you have to be ready to hold volume up, power and home as soon as it reboots to boot into recovery. You will see recovery booting in blue in the top left corner. If you don't get the key combo in time you will probably have to do the whole odin thing again as the stock rom without root will replace recovery upon boot.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] agaurav:
Thanks enewman. I was able to do this and the screen has Team Win Recovery Project v.2.8.7.0 with Install, Wipe, Backup, Restore, Mount, ... tiled options.

I guess now I need to wait for you to upload the ROM and then do something with that file and this TWRP screen, correct? Or can't I download the I747UCUFNJ1 ROM and download that? Or would that not work once I got the FNJ2 version? I don't care to be latest/greatest when it breaks my phone anyways.

Eagerly waiting and thanks so much.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] agaurav:
Thanks enewman. I downloaded the file. By any chance do you have a pointer to the tutorial that explains how to use this zip file with the TWRP on the phone with Odin? There are many online and I want to make sure that I use the one that is simple and works.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
The file is a zip file which needs to be flashed from twrp like a custom ROM. Odin is not used to flash the nj2 ROM.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] enewman17:
With all custom recoveries like twrp or cwm when you flash a new rom the steps are as followed.

Once downloaded, copy the zip to the root of your external sd card or internal if you don't have one, that could be an issue though if you had to format the internal sd before flashing... use an external sd if possible. Don't extract anything leave the zip as is.

Boot into recovery, Phone powered off... hold Volume up, Home and Power till you see "recovery booting" in top left corner.

Wipe, go to the wipe tab and do a factory reset. This is normally all you need to do. Sometimes doing an advanced wipe including the internal sd is necessary.

Install, go to the install tab. Choose the downloaded zip you want to flash. Then execute the install.

Sit back and wait for install to finish

Reboot

Setup rom

Odin is a utility we don't have to use much... when we use to have .tar files that we could use with odin to restore our devices. Or like flashing a custom recovery initially without the device being rooted.

Hope this clears things up a bit for you.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] agaurav:
This definitely helps. Thanks a lot. I will use an external SD card. I started the process with TWRP. It did skip the MD5 check. The Install was fairly quick. Less than a minute. Now the reboot is on the AT&T logo screen and am waiting patiently for it to supposedly setup the ROM?

I was able to recover the phone and it is working fine except for one thing. I need to use Airwatch Inbox client with Airwatch Agent and Samsung services. This is for work email and calendar etc.

Unfortunately, now I can't get that to work. Not sure what is the reason though. I go through the server/email setup and installation in Airwatch Agent and things are fine. It should get to a point where it asks for installing the Inbox client and Content Locker. But instead it says, "Airwatch Samsung Services" will be uninstalled.

I am guessing that something in the ROM doesn't play nice with KNOX and I can't get Airwatch to work. Any ideas? Can I disable any potential super-user or root capabilities in the phone to get Airwatch and KNOX to work? Thanks in advance.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:

will it be helpful if I flash S3 stock recovery only because I don't have stock rom.tar.md5 (the Odin flashable) or do I have option unroot than of just flashing the stock recovery and data reset will solve problem. I later also updated to NJ2 through your other post regarding that.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] silentjet:
Got a problem, couldn't avoid it.

I have pure i747 device, never rooted, never modified, the only used in a pretty standard way.

I'm using a device outside of US, so never saw software upgrade notices.

These days i decided to upgrade a device from 4.1 to latest fw manually, so I started to flash official OTAs one by one.

And till EMJB every thing was fine: reboot recovery, apply update from ADB, reboot, factory reset, reboot recovery, apply update......

So now I'm on EMJB (aka 4.3) and wanted to upgrade to official Kitkat (FNE4 or higher). I was able to find the only one image called UCUFNE4_SGH-I747_4.4.2_OTA_update.zip

However when I pushed next update via ADB sideload mechanism, the recovery does not want to update a device with a following errors:

E: failed to verify whole-file signature

E: failed to verify whole-file signature

E: signature verification failed

And as per my understanding that error is just because the OTA image is modified (root was injected or so).

Could you please point me to pure OTA image for upgrade from EMJB to any next?

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Chupacabra117:
so you were on 4.1.1 rooted, and then straight up flashed the newest bootloader and modem? Or incremental?

and then after that, flashed your Carbon Rom 4.4.4?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] newbe1droidx:
Sorry been gone a while, did not straight up to latest bootloader/radio. Have decided to download each one and go one at a time till I get to ne1, maybe higher if needed for ROMs. That may be the safest way to proceed. Unless its safe to do the two step update, that's what I,m unsure of.
