If you want to update op on Blackbox, 2.3 based on xxuenaa was released on the 17th. Installed on slot 1 and seems to be running beautifully. Options in aroma to not install recovery or kernels. I'm sure it will be fine on stock slot, but I have not tried it there yet. I'll try it tomorrow after a backup.

EDIT: Could not sleep, so I put it on stock. Working perfectly fine. ☺

OTA Update....Be Safe

For some of u that did not freeze or uninstall ATTsoftwareupdate.apk just be careful.....:cool: Here's the latest update from SAMMY_KITKAT_UPDATE We Do Not know if ATT would Force OTA update and then patch kitkat for going back to MK2. As far as right now if u tried MLD 4.4.2 LEAKED u still able to going back to MK2 if u follow my MK2 tar file thread. Since we don't have root method yet for MLD_4.4.2_KITKAT.....so be safe untill we found root method and maybe we get an Safestrap for 4.4 kitkat update by then.....:good::cool::good:

On 2.3 it's under display settings/wallpaper/lock screen the bad part is that you can only select from SamSuck wallpapers so I decompiled the Apk and replaced them with dark wallpapers.

[AT&T Samsung Galaxy S 4 General] guut13:
Thanks for sharing what worked. I can see flashing the APN zip will save you from having to enter in the APN manually, but the rest may be a little redundant.

I was on NJ4 when I tested it and all I did was flash the ROM and NJ4 modules.

The modem doesn't get touched when flashing the ROM, so you don't need to re-flash it. ROM is already rooted and the binaries are there, so no need to flash them separately. That said, it is not running the latest version of SuperSU, so feel free to flash that one to upgrade ;)
[AT&T Samsung Galaxy S 4 General] shawn1976:
I've been out of the flashing loop for about a year and not used to a locked bootloader so I figured a little overkill wouldn't hurt. Lol

MK2 to NJ4, Then 4.4.2 Touchwiz Rom Install (via Safestrap)

Hi All,

I'm currently running MK2 (never took NB1 OTA) with a customer ROM (Graviton). Since this is pretty old now, I'm contemplating going back to stock and allowing the update to NJ4 to occur. I would still like to run the 4.4.2 Touchwiz ROM that I currently have. I should be able to do that on the NJ4 base as long as I flash the NJ4 modules after the custom ROM, correct?
[AT&T Samsung Galaxy S 4 General] jt1998:
yup. follow the instructions in the first few posts, specifically how to update to NJ4. That's what I did.
[AT&T Samsung Galaxy S 4 General] mswal2846:
As a variation, do you think I could do a backup of my Graviton System (under Safestrap) prior to the ODINing back to Stock, then after upgrading, rooting, reinstalling Safestrap do a restore of that same Graviton System? That would be pretty cool, if works!
[AT&T Samsung Galaxy S 4 General] jt1998:
no harm in trying. Make sure to backup to extSD before ODIN so you don't lose your Graviton backup. I have a feeling it wont work b/c MK2 to NJ4 or you'll get FC errors, but worth a shot. worst case you factory reset your NJ4 and start again. I would also TiBU your apps to speed it up in case it doesn't work.

You must use stock slot
[AT&T Samsung Galaxy S 4 General] shawn1976:

yeah but don't i need to flash the rom before and then restore the backup of that rom?

sry im a noob here
[AT&T Samsung Galaxy S 4 General] Sterben Pistole:
I would suggest doing a clean flash of the GPE ROM on the stock slot. If you have your Odin files and don't do things that might be a risk and cause a soft brick while away from home, you will be set to go with just the Odin files.

I also forgot to mention, i f you're gonna be flashing a new rom I (personally) suggest to just backup photos, music, and other miscellaneous files, but restoring app backups sometimes gave me a hard time cause one app of 23 would be giving me some error or something. Then again, that's just my two cents on it.
[AT&T Samsung Galaxy S 4 General] mswal2846:
I think it would be helpful to get some additional information. What is the Android Verison, Kernel Version, and Build of your phone? What didn't "work?" Did the phone start up with the ROM? What issues were you having?

Did you follow the directions here (http://xdaforums.com/showthread.php?t=2616221):

1. Copy Files to ExtSdCard

-- ROM install zip file

-- ATT Kernel Modules zip

-- UPDATE-SuperSU.zip

2. Reboot into Safestrap and Wipe

Wipe --> Advanced Wipe --> check everything except extSdCard

3. Install ROM Zip

Check ROM notes... may need to replace updater-script

4. Install ATT Kernel Modules

Modules must match the kernel you are running and can be found here.

NJ4 base users, flash ATT_NJ4_Modules.zip

NI1 base users, flash ATT_NI1_Modules.zip

NC1 base users, flash ATT_NC1_Modules.zip

NB1 base users, flash ATT_NB1_Modules.zip

5. Install SuperSu.zip

Latest stable version can be found here

Current play store version is UPDATE-SuperSU-v2.36.zip

6. Reboot

7. Check APN Settings

Configure if necessary

Hello everyone, please I need some help:

I am on NB1 stock rooted with Safestrap installed.

Can I use the Alternative Method for Safestrap Users to go from NB1 to NJ4?

Thank you,
[AT&T Samsung Galaxy S 4 General] jt1998:
I tried that but for some reason it didn't work for me, and I ended up using the primary/1st method. I did make a backup of everything using TiBu onto my ext SD card so no big deal. Just be prepared in case it doesn't work, that you have everything backed up and, can do the alternate method if needed.

Good luck! I was on SS using Goldeneye ROM v38 or something with NB1, and then went to GE 45 and NJ4, which I'm still on.
[AT&T Samsung Galaxy S 4 General] Alverik:
Thanks for the heads up, I have been running NB1 since it came out, maybe it’s time to get a full wipe to refresh the system. It’s good to have an app like Titanium Backup to get everything back.

Have you notice any improvements from NB1 to NJ4 or do you think I should wait for the lollipop update?

Thanks again,

Phoenix ROM 10.0 never boots up when I flash it with SS 3.72. It just sits on the Samsung Galaxy S4 screen and after around a minute or so it reboots into stock recovery for some reason. I'm on NB1 if you need to know.

STEPS I DID IN EXACT ORDER

1. I went back to stock via Odin (flashed NB1_Rootable_Stock), rooted, installed busybox, and SS 3.72

2. Put Phoenix 10.0 and 10.2 on Ext. SD-Card (Class 10 if you need to know)

3. Factory Reset and Advanced Reset via SS (tried without doing this)

4. Flashed Phoenix 10.0, I used the full wipe option in Aroma(even tried to install without any of the mods)

5. Flashed 10.2 (even tried no flashing the update with no success)

6. Flashed NB1 Modules

7. Flashed SuperSU v2.16

7. Rebooted and it ONLY boots into Stock Recovery after a minute of being on the SGS4 Logo that comes up directly after the vibration.

That's about it. The only thing I can do is boot into Stock recovery (kinda cause it does it automatically...) and boot into Download Mode. If you know how to fix this please try to reply to me if you can because I'm getting a bit tired of AOSP, and I also really like the S5 TouchWiz (especially the Camera app).

I'm still on mk2, never updated. I've had SafeStrap 3.71 installed since the date that version was released, with the original stock ROM still preserved in Stock Slot and HyperDrive RLS12 since day 1 as well.

Fully satisfied with my current setup, except for storage space. I think I'm going to flash HyperDrive 12 to my stock side.

Since my versions of SS and ROM are over a year old, I'm having difficulty researching to full confidence and just want a nod of approval for the procedures.

I've backed up my apps.

I've backed up ROM Slot 1 HyperDrive 12

I've backed up stock ROM in Stock Slot.

I've got the HD 12 zip on ext sd

I've got the correct modules on ext sd

I've got my Slot nandroids on ext sd

I've got SS 3.71 apk on ext sd

I'm going to boot to SS recovery and wipe ROM Slot 1.

Then completely delete ROM Slot 1.

Then full wipe Stock Slot.

Then restore my backup of ROM Slot 1 HD 12 to my Stock side.

Then flash modules.

Wipe cache/dalvic.

Reboot.

Does this sound right or should I be flashing the HD 12 zip instead of restoring my backup to stock side?

[AT&T Samsung Galaxy S 4 General] JustMeToo:
I got a used AT&T S4. It had MF3 with Android 4.2. I odined to MK2 and now it says in 'Baseband version' "Unknown". I odined a couple of times and it still says it. I also had flashed it with the RegionLockAway app. Can that be the cause? I had flashed that app on other phones with no problem. Because of the 'Unknown' issue the carrier is not recognized.

Actually, sometimes it does say the MK2 in the baseband version and sometimes it says 'unknown'. Any idea where I should look for the problem. It seems like it's hardware but I'm not sure.

Edit #2: I checked with the Terminal Emulator the bootloader and it says it's the MK2 even though the "unknown" still appears in the baseband.
[AT&T Samsung Galaxy S 4 General] guut13:
I'm assuming you are referring to "baseband" in the settings menu? If so, that is referring to the modem.

Not sure what's causing that but I'd assume Odin to stock should flash the modem too. Which MK2 odin file did you use?
