[Q] NJ4 Safestrap Change modem - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi guys,
I recently got my s4 and found out it had a locked bootloader, boo. After a lot of research I was able to get it to install safestrap with Imperium rom. I also had to change my modem and went through the steps to changing it like 3 times and ended up on NJ4. I was previously on MF3 and had great signal but after all these changes and going to NJ4, it seems my signal has gotten worse. I want to know if I can change my modem on the fly with a zip or something faster through safestrap or do I have to go through all the odin steps again in order to change? Its a lot of damn work and very time consuming, so I thought I would ask before doing. I do not think I can even go back to MF3, right? I followed these steps: http://forum.xda-developers.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642
Thanks for any help,
Jose

You can flash a modem zip with safestrap. See rockrat's modem thread in the general forum.

[Q] Bricked i337 -- URGENT

Hi everyone,
I am new to android mods and such and I may very well sound like an idiot. However, even though I know little to nothing of what I am talking about I am in dire need of help. I never did any heavy modifications like custom ROMS but I merely rooted it and installed some tweaks via the xda installer. After toying around with one of the tweaks I seemed to cause an annoying random reboot which would happen when I would sometimes go to unlock my phone. Fine, I could deal with a few reboots here and there. However, my phone recently got stuck on the AT&T loading emblem and stood in my pocket for 2 hours draining a lot of battery and has not been resolved since. I am unable to enter safe mode and I tried a few guides to flash it to stock but I honestly have NO IDEA what I am doing. I am aimlessly following guides here but there is so much variability therefore I feel as if I would have the most success with personalized help.
What do I do? Please use simplified terms along with (relatively) full steps. For example, if I were to flash something I would go into recovery mode with home + vol up button factory reset, and the AT&T logo would still be there, frozen.
Things I have tried but have probably done wrong:
Factory reset
Install custom ROM
All and ANY help is appreciated at this point, I am desperate.
Thank you,
Suprr
Also, my ultimate goal is to install http://forum.xda-developers.com/showthread.php?t=2520418 this mod, or at the very least get the stock ROM working so my phone is usable.

I am assuming that you havent yet taken the OTA update to NB1 and your base is MK2. Or, do you have a MDB/MDL bootloader?
If MK2: You have to flash the full stock Mk2 firmware using odin. Download the "Full odin tar files" from the All things ATT thread
if MDB/MDL: Download the stock firmware from sammobile and flash using Odin.

He must have determined you are not on mdl/mdl firmware. Those firmwares would allow you to easily flash custom roms, nb1 is not as easy and limited to touch wiz based roms. Do you know if you had a custom recovery, twrp or cwm?

Boot into recovery and do a factory reset. That should get you past the bootloop
Ps, the first boot is going to take longer than normal. Give it a good 10 minutes

You're on mk2 firmware now. You'll need to root it using safe root and then put safestrap on in order to flash that rom. Look in the general forum for index, all thing mk2 and nb1. There's a lot of info there so read it carefully

Throwing in the towel, I need help.

Hey all, I just acquired the SGH-I337 as an upgrade to my Galaxy S3. I can not for the life of me get a custom ROM running on it. My goal is SlimKAT because I like the ROM and have been using it on every phone since my Samsung Vibrant. Any time I'm flashing something in ODIN that has anything to do with ABOOT, it fails, soft bricks the device, and I have to reflash in ODIN all over again.
Please let me know what information I can provide to help with this. I've never had so much trouble with a phone before.

Please tell us the firmware of your phone (baseband, modem, etc..)
I337 has locked bootloader if your firmware is MF3 and above (MK2, NB1, NC1). You have to use the safestrap as a recovery if you want to flash the custom roms. If you want to flash SlimKAT you have to the SlimKAT safestrap version if they have one.
If he had to use Safestrap he can't use Slimkat as it's AOSP and he can't change the kernel. Chances are if he was getting issues flashing aboot then he's on a newer version. Confirm it in the about phone section of the settings though.

You can't go back to older bootloaders ever. Sounds like you are updated to something that you can't flash custom anything to. So safestrap is the only way to go with modded touchwiz based roms.

I was able to successfully unbrick the phone by using Odin to get it to MK2, although Wifi didn't work. Now I'm trying to get it back to the latest firmware so that I can sell it.
UPDATE!
Phone had been successfully reflashed to firmware NB1, with everything seemingly working. This phone seems so much more complicated than the S3 was, thanks locked bootloader.

I would use the non root one then let phone take the NC1 OTA update.
That shod give you a clean slate to sell the phone or you can root NC1 with towelroot

[Q] Updated to 4.4.2 KitKat any Rom suggestions?

I recently updated to 4.4.2 KitKat on my AT&T Galaxy S4. I am rooted with safestrap installed. I am new to Androids and I was wondering if there were any roms available for baseband I337UCUFNB1, I found GoldenEye but it won't work on my baseband without a certain file being flashed through Odin first, every link I have come across to download this file ends up saying file not found. Are there any safe roms out there that I can use? I've searched all over and found some, but it's just kind of confusing to me. Thanks in advance!

You're not going to brick your device. You may have to Odin back to nb1 in the worst case. Do the ota to nc1 and root with towel root. Then use safestrap.

Help sought: Screwed up my S4 and seeking a fix

Note: Relevant device info will be provided below.
Dear techwizards,
I've been trying to root my phone for a while, I've done it before: both my S II and S III were international variants, and rooting those devices was very simple. But after getting an S IV from America and consensually downloading a samsung issued update -- I had yet to read up on the disadvantages of knox -- my rooting and android experience took a turn for the worse.
Long story short -- I know developers are a proud bunch who value their time -- I tried rooting my phone yesterday after almost smashing my phone on a coffee table. They say it's a well known side effect of Touchwiz, but I'll leave that to you.
I used a towelroot.com root -- a wonderful tool, if I may say so. After that, I visited the CM website and picked out the compatible CM11. I never got to flashing it though, as my problems arose while installing a recovery.
I had downloaded an app, a something recovery or another. They had an option to flash recoveries on there--it would download your recovery for you and do all the work, which seemed plausible as most video tutorials demonstrated. To my astonishment, doing so bricked my phone.
I tracked back, looked for the samsung stock rom, downloaded all 2.2 gb's of it and flashed it. It worked. My phone was functional but I suspect something within it stinks. My device, apparently for security reasons, wont let my wifi or 4g to establish a connection. It's making it impossible for me to fix this problem as I can't root my device or flash a custom rom.
About Device:
Pre problem I was running a:
SGH-I337UCUFNC1 baseband. Build Number ending with: NC1.
Android version: 4.2.2
Post problem:
Baseband: I337UCUFNC1
Build Number: JSS15J.I337UCUEMK2
Android version 4.3.
If I could find my original stock 4.2.2 NC1 version and get simple instructions on how to re-install it back to stock version, I'd be very grateful.
If you know how I could fix the internet issue on the MK2 one, and provide some simple instructions of how to root it, I'd be grateful too.
If you think neither would work, and have something else in mind, Im open to your suggestions.
Much Regards,
Y

Since your bootloader is already locked, you might as well Odin to stock. Odin to NB1 then use stock recovery to flash the NC1 update from a zip file on a microSD.
Part of the problem is that the NC1 is not 4.2.2 like you listed, but 4.4.2. That's the update you applied that started the sordid tale. When you were on 4.2.2, with bootloader MD<something>, you could have flashed CM or whatever, because you would be able to have TWRP or CWM recovery. When Samsung pushed out a 4.3 update (MK2 I believe) all the unlocked bootloader fun was over, probably permanently for this phone.
When you flashed MK2 firmware (4.3) onto the phone, parts of it don't work with the NC1 baseband, causing the problems you've seen. If you Odin NB1, then do the quick zip update from stock recovery to get all the way to NC1, you'll be back to stock and everything should work.
Once that's done, you can go through this process:
1. Root with Towelroot.
2. Install SuperSU to manage root access. (You might have to reboot, it's a 50%/50% shot... sometimes it hangs trying to disable Knox... no worries just reboot)
3. Install SafeStrap... it will create the safestrap recovery. You might need to install SELinux Mode Changer app (from play store) and set to permissive, to get Safestrap installed.
4. Boot to the SafeStrap recovery. Install any touchwiz rom. Only touchwiz compatible roms will work. I liked GoldenEye.
When installing touchwiz ROMs, typically one flashes the ROM, then SuperSU, then the NC1 modules, then the ATT BuildProp/APN file. Sounds complex but goes quickly. Some roms have some of these things built in.
Good luck! I eventually decided I didn't like the ATT Samsung restrictions of the locked boot loader, and bought a T-Mobile M919 variant of the S4. Unlocked boot loader. Woo hoo. And works fine on ATT.

Thanks in advanced!
Try to odin to stock (make sure you get the correct files), root, install SafeStrap following the instructions here: http://forum.xda-developers.com/showthread.php?t=2448942
After that you need to flash the rom, kernel modules (you can get them here: http://forum.xda-developers.com/showthread.php?t=2447764), then after that you flash SuperSU (if you don't have that file then here it is: http://forum.xda-developers.com/showthread.php?t=1538053 DO THESE STEPS I JUST SAID IN THE SAME ORDER LISTED HERE: Flash ROM, correct kernel modules, and then SuperSu.)
If the same error ocurrs then it's most likely the rom just isn't compatible with you device. Also, make sure it's an S4 Active rom not a normal S4 rom.
NOTE: I do not own an Active, but doing some 5 minute research is what helped me figure this out for your device.
Ok, I´ll try! Sorry, but everything I did before, unsuscefully is the result of many hours of forum research......problem is....I don´t know a lot about this....yes, probably shouldn´t mess with it, but truth is I live in Argentina, and wifi + bluetooth stop working with stock rom....no matter how many times I hard reset it so I figured changing rom might solve it........
I went to through the same you're going through with my S4. I ended up flashing the wrong Odin files like 5 times before I figured out what file to flash, lol. Glad to help

after you flash with safetrap, does the kernel have to be flash with safetrap or with Odin? i did root my GS4 using Odin and have the I337_NJ4_Stock_Kernel. can i use that one or do i need to download any other tipe of kernel??
You need to flash the kernel modules via SafeStrap. The NJ4 modules (and other modules) can be downloaded from here: http://forum.xda-developers.com/showthread.php?t=2616221 navigate down to the KitKat Install instructions, look for step 4 (Install ATT Kernel Modules), in the first sentence click the hyper link redirecting you to AndroidFileHost, and then download the corresponding Kernel Modules to FLASH DIRECRLY AFTER EVERY ROM YOU FLASH.
THE FILES LINKED ARE FOR NORMAL S4 ONLY.
Sent from my SGH-I337 using XDA Free mobile app
Those two things are different...
You can only flash the nj4 kernel via Odin using the ap slot. I'm not sure if safestrap can flash kernels, because we're not meant to or we would be using twrp.
The nj4 modules should be flashed along with what ROM you're using during use of safestrap.
I was referring to the stock kernel modules (what I linked him/her to) needed to be flashed after the ROM each time. Also in SafeStrap, can't you flash stock kernels? I'm pretty sure you can. If not then I'm just crazy lol.

Thanks!!
You need to use the Stock slot. Any other slot causes errors on most roms, and how do you have two bootloader versions? I'm thinking that MF1 is your BL and NE3 is baseband or something.
Sent from my SGH-I337 using XDA Free mobile app
Do not use Safestrap...you have an unlocked bootloader and have no need for it.
It will not work well with an unlocked phone like you have as the recovery is designed for locked US based carriers.
I think he means that he's SIM unlocked. I'm not sure they have an unlocked BL for the Active. If they do, then he should go ahead and use TWRP or CWM.
