Suggestions for phone accidentally updated to locked bootloader - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hey all,
So I gave my cousin my old GS4 and it was running GPE fine. I think she accidentally updated it and now its locked. I got safestrap installed now and I'm trying to decide if I should get her a safestrap rom or just stick with what she has now. I don't think there are any serious problems... it seems like a GPE rom and MTP works.
From what I read it seems like all the GPE safestrap roms don't have that working... What do you all think I should do? If you're on safestrap, what roms are you all running?

What makes you think it was updated? If it's still on a GPE with MTP working it should be still on the old bootloader because that requires a custom kernel.

Well when I looked at her phone it was missing xposed and some other things. So I tried getting into TWRP and that was gone too. Couldn't reflash it. Checked the phone info and it said NC1. I was able to install safestrap, so I figured some update got weird. I did get xposed back on it so I think I'll just leave it alone for now.

Might have just been a modem update. Try typing getprop ro.bootloader in Terminal Emulator to be sure. If it's MDL/MDB you're safe to just reflash TWRP whenever.

safestrap and Google Edition Att S4 i337

Last night I flashed http://galaxys4root.com/t-mobile-galaxy-s4-roms/google-play-edition-rom-for-galaxy-s4/. I am on safestrap mk2 i337 4.3 rooted. After I installed the GPE, I did a wipe dalvik and cache then reboot. My Att i337 rebooted the Google boot screen started then it started the Android is updating 115apps. After that it says starting apps and just stays there and doesn't boot any further. I tried to flash Loki doki, different mk2 kernal modules. Nothing I tried could get it to actually start the apps so I can put in wifi password or anything. Usually if a rom is not compatible it doesn't get this far. I feel like this can work since it got so far using safestrap. We don't have any Google play edition roms or kitkat roms and this is closests. Can anyone help me or try to figure this out?

I'll admit, you got further than I would have expected but the facts remain... GPE 4.3 uses a different kernel than touchwiz based 4.3.
Your best best is to install this AOSP theme... http://forum.xda-developers.com/showthread.php?t=2304251
It will run on goldeneye 20 in the ATT thread or just install a ROM that already has it incorporated, such as Blackbox or Purified.
I haven't seen blackbox or purified anywhere. I'm no developer but it's just SO close it just seems like it can be done. I do understand what your saying though. I just tried because it was basically stock.

So close, yet so far away... until the bootloader is unlocked.
Look here for a list of ROMs that work on MK2, including those two... http://forum.xda-developers.com/showthread.php?t=2616221

Note 3 wont update to kitkat

Hey this is my first post and Im sorry if some of this is a repeat, I looked around for a little bit and wasnt able to find any answers.
I have a note 3 on verizon and i finally got it rooted on MJE. I have SuperSU installed as well as xposed installer as well as wanam xposed and a couple modules. I was trying to update via OTA and it constantly gives me error 402. I have tried hiding superuser and it says on odin? i believe that im on the offical rom and everything.
i just cant get onto kit kat no matter what i do. it downloads and once it tries updating i get the error.
Is there anything im really missing out on with kit kat? I want to install S view all covers and also want the XLTE. thats the main reasons for me wanting to update.
Is there something wrong with my phone? How can i get the update now? Thanks

You need to be unrooted stock to accept the OTA. Currently no way to root the ota. However there is a kitkat build (nc2) that was rooted. This is the build that everyone is working off of, so you can just flash the firmware / nc2 rom and you will be on kitkat rooted.
Thanks for the reply!
I've heard of people still taking the Ota while keeping root by putting supersu on survival mode though. Should I check that off and then click unroot in Supersu to take the Ota? Thanks

You do NOT need to be unrooted, but you do need SuperSU to be in survival mode.

Have you ever installed safestrap or anything similar?
Also remove all xposed modules, etc.

Try installing just the nc4 radio for xlte. Have you tried the leaked NC2 KK? I'd stay rooted personally ... samsung stuff has too much bloat and will run like a pig.

Nope I just I have supersu. I disabled superuser and then I Uninstaller all the modules. I also uninstalled the framework for xposed. Is there anything else that could be causing it?

You may have to reflash MJE and reroot it.

[Q] Had to odin to stock.. how can I get twrp back?

I have a i337. I had the GPE 4.4.3 ROM by Danvdh but I thought it would be a good idea to "clean my phone" by formatting it but it ended up getting rid of some prebuild things on my internal sd card.
In any case, I ended up odining back to stock and now i'm having trouble getting TWRP back on my device (and thus being able to flash ROMS.)
As of now there's nothing on my phone so really any path would be fine with me (i've been reading and tinkering with this NB1 downgrade to MK2 then going to NC1? but that revolves around safestrap? I know its based off of twrp but its only compatible with stock roms? I like the more GPE esque roms. and not being limited...
Can someone help please? If possible in real-time over an IM service or something.

What firmware did you flash? If you flashed anything newer than mdl you're not going to get twrp.

Well thats a bit concerning... can I just reflash something earlier? As I said theres nothing on my device so I am not concerned about data... sadly i'm not too sure what I flashed but I think it might have been NB1...

You can't change it once you've updated. There is a single GPE working on Safestrap but not all features work.

ATT S4 KitKat 4.4.2 - Is Cyanogenmod possible? alts...

Hi All,
Appreciate the guides and community here. Looking for a little help on my ATT S4 KitKat 4.4.2. It's rooted via Towelroot.
I want to run a custom rom that isn't slow. I have Odin, proper Samsung USB drivers.
1) Can CNW be used on my phone to boot to recovery? If not, what are the alternatives and how do I use them (is there a guide you can share)?
2) Do I have NC1 on my phone, what the heck is NC2, NC1-what does this mean, is it relevant?
Thanks all
-Christian
If you have updated your phone to the att 4.4.2 firmware then you should be on NC1 which means you cannot put cwm or any CM rom. The only recovery you can use is safestrap. After that you can only flash rooms the specifically say safestrap compatible and you must flash the att_nc1 module after flashing rom for WiFi to work. Read the safestrap thread under the development section before doing anything.

Yes, I would also read over All Things ATT/MK2 etc in General--:good:
Those numbers NC1 etc are your build version. Can be found under Settings/About Phone. It will dictate what you can and can't do on your phone--We have no NC2 yet. :good:

Thanks. I have nb1. No luck getting safe strap to take. Install completes but does not recognize status as installed or allow boot to recovery.
I have rooted, supersu, busybox, and no luck with safestrap. Any ideas.
Upon booting I notice an icon that looks like a unlocked lock beneath the samsung logo. Touching it does nothing...
Thanks for getting back to me

I don't use safestrap. So not sure. Did you wipe all including system. And flash to correct slot. Stock slot I believe. Use correct safestrap. Also need sellinux, spelling? The lock is suppose to be there if rooted. Read the last 20 pages of the hash code safestrap thread plus the op. And same on All Things ATT/MK2 in General. May give some ideas. ☺

Aha! Safestrap running and custom ROM installed. Is there an index comparing all Safestrap/Touchwiz based roms? Runnign SHO right now and it's pretty bland (resolution looks low too).
I'm looking for something like a stock nexus experience with WiFi tethering.
thanks for the help mates

Not sure on index. Best though to try them yourself as they don't always work the same on different phones.

Iam all for custom ROMS. I made one for the Tab3. If all you want is the stock Nexus experience, you could just download the Google Now Launcher which is Google release the AOSP launcher. Then if you want the individual AOSP apps, you can do a search here or a google search, and you will find XDA threads that provide the apps with installation instructions.

[Q] I337UCUFNJ4 AT&T Galaxy S4 4.4.4 only download mode

i root my gs4 with odin, everything went fine but I wanted to get my gs faster so i downloaded kernel for gs4 and flashed it. mistake here. i didnt check if it supports 4.4.4. it only support devices under 4.3 so.. no wifi. that was the problem i had other than that, all was good. than I downloaded some OTA file for my gs4 and when i tried to flash it with safestrap, it kept said fail. so i thought it's maybe because i already have OS installed... so i wiped system,data and i tried to flash that OTA file, fail again. now im screwd. there is no OS on my gs4. when i trun it on, it vibrates, than reboots and than goes into Odinmode and say something like "nornal boot not possible" in red.
so i spent couple days searching how to get my phone work again but everything i tried didnt work. and for galaxy s4 sgh i337 nj4 version 4.4.4 it even made me think it was made just for me.
i tried kies, failed it told me to do emergency recovery but my phone does not show on list.
can anyone please help me.. Im new to Samsung Galaxy..

You'll have to use the ODIN file from this thread: http://forum.xda-developers.com/showthread.php?t=2674223
Flash that in ODIN, use the rootable version if you want to root it using towelroot.
Besides that, you can't flash any custom kernels on the S4 unless you're on the 4.2.2 MDL bootloader, and there's no way to get back to that from 4.4.
