[Q] rooted NC5 downgrade to aosp? - Galaxy S 4 Q&A, Help & Troubleshooting

Hi everyone,
I have a question... I took the NC5 OTA update not knowing it would lock up the device, in fact the first time I turned it on it was the only option to upgrade or delay it. So I've completed gogolies OTA downgrade to rooted upgrade (NC5) and it worked! every happy about that. However I really want something pure AOSP. Can I downgrade again to an older version in order to load something like AKOP or Cyanogenmod? I looked around for 4.4.2 roms and was unable to find anything pure... when I say pure I mean the AOSP images, icons, software nothing designed by Samsung.
Thank you,
Ck

Why do you need to downgrade? You can just flash any custom rom you want.
There are a lot of AOSP roms. You can find them in the Original Development section.

Thank you for the reply however I've tried to install AOKP and CM10 both on slot one and both failed (booted to black screens) and I don't see any I545 roms on this site. Could you point me in the correct direction? I'm currently running rooted 4.4.2 NC5 on i545
Thank you again,
Ck

Hi,
Please check for your specific device forum .
http://forum.xda-developers.com/galaxy-s4-verizon
If you flashed a ROM from the threads on this forum it's very likely it didn't work because the international S4 is different from Verizon one .

I can't get any other custom ROMs to work on my S4

Hello, I am new to this so forgive any misused jargon. I got an AT&T Galaxy S4 right around Thanksgiving and like a fool I couldn't wait to root it and install ROMs - so I did.
This is the current version of my phone after rooting it. I am on stock-rooted right now.
Model #:SGH-I337
Android Version: 4.2.2 (It was 4.3 straight out of the box, BUT it was NOT the OTA update).
Baseband Version: I337UCUAMF3
Kernel Version: 3.4.0-812098 [email protected] #1
I used this method to root it: (Since I can't post links yet, search"root galaxy s4 at&t mj7" and it should be the first video, uploaded by Tomsgt123)
Shortly after, I installed ROM Manager for CWM and I have CWM 6.0.4.4 but I never used it.
Then I installed Titanium Backup even though I also never used it.
I discovered SafeStrap and installed version 3.65 (TWRP v2.6.3.1) and I was able to successfully create a ROM slot for Hyperdrive, which
installed smoothly for me. However, when I wanted to try out other ROMs (Cyanogenmod, PAC-ROM, OmniROM) they wouldn't work.
After flashing them, my phone would turn off (or the screen stays black) and I would have to hold the power button to reboot it so I can revert to the stock ROM in Safestrap.
I really want to try another custom ROM, because I'm jealous of all the cool themes people have. Am I doing something wrong? Or did I ruin something during the rooting process? Any feedback is appreciated.

First off MF3 is not 4.3 right out of the box. MF3 is exactly as you wrote it, 4.2.2 android firmware. As you have found ONLY safestrap will work on MF3. To flash Roms you can ONLY FLASH 4.2 based Roms. Check out this link to see WHICH ROMS you CAN flash http://forum.xda-developers.com/showthread.php?t=2428254 with safestrap.
You won't be able to flash CM or other asop Roms from my understanding. You can flash the Google Edition ROM 4.2.2. Again check out that link on the first post it shows Roms that can be flashed.

[Q] [QA] Been googling/searching... confusion on rooting AT&T i337 UCUFNI1

I'm not trying to be lazy. I've spent time searching for how to root my S4 i337, but for a newb like myself the process is extremely confusing since there seems to be so much different information out there, and not a lot about i337. From what I've discovered Towelroot no longer works as an option after I upgraded to 4.4.2 and I've tried other approaches which have failed as well. So without further ado
Is it possible to root a galaxy AT&T galaxy s4 i337 running 4.4.2 baseband I337UCUFNI1 ? If so, could someone share the links I should look at to accomplish this task?
Maybe I need to revert back to an earlier android release ? which I'm fine doing assuming something like this link should work: http://www.teamandroid.com/2014/03/30/update-att-galaxy-s4-sgh-i337-android-442-kitkat-goldeneye-rom/2/
After I revert (assuming it's needed) could someone recommend the next steps(links/threads) to get me to either a custom rom or latest 4.4.2 stock build (I'd prefer a custom rom for fun, but i'm fine with whatever is easiest.)
I have Odin installed and understanding getting to download mode, but deciding which "link" to follow out there for instructions is not easy for a beginner so any recommended 'easiest' approaches for my device would be appreciated.
TIA

Subscribe to All Thing AT&T. It has all the information needed, including how to root NI1.
root
http://forum.xda-developers.com/show...php?p=55537351
look there for instructions. it works . Flash the older kernal using odin, if it fails to flash the first time. Repeat. After u get it to flash. Then run towelroot. After u install towelroot. Flash the ni1 kernal. You will keep root. Thats how I did mine.

[Q] SafeStrap-compatible T-Mobile ROM (w/ WiFi Calling) on unlocked AT&T S4?

Hi all! Forgive me first off if anything comes off as a silly question, I'm fairly new to the whole idea of ROMs.
Here's my current situation. I've got an unlocked AT&T Galaxy S4 which had the 4.4.2 NI1 OTA update installed. I've since installed SafeStrap and a 4.4.4 "Pure Nexus" ROM in the stock slot.
With the newest SafeStrap 3.75 beta installed and slot ROM installations working, I'm interested in finding a T-Mobile/MetroPCS ROM (I currently have MetroPCS service) for the WiFi calling feature. I've found a few stock ROMs that will boot in Slot 1, but unfortunately all of them seem to have a modem issue that I can't resolve (unknown baseband version, no wifi/cell). Those ROMs had modems available for download, but only in .tar format, so I can't install them with SafeStrap.
My question is, has anyone been able to pull off running a T-Mobile/MetroPCS ROM on an unlocked AT&T S4 with SafeStrap? Thanks in advance for any help, sorry again for being such a noob. :crying:
EDIT: I see that this thread (http://forum.xda-developers.com/showpost.php?p=53758259&postcount=2) has some T-Mobile ROMs listed, would installing them in a SS Slot make them behave any differently than normal?

Wow, that actually looks like exactly what I needed! Thanks so much! Guess I should have done a bit more searching, heh...I'll post back here with any updates with a Slot-based installation.
Update: the guide linked did not appear to work on a SS Slot installation, but did work just fine as a stock ROM installation. I'll be trying a few more from that other thread later on and post if any work on a Slot installation.

[Q] Trouble flashing new roms afterLP stock flash. (N910F)

Hi guys,
I really hope someone can point me in the right direction here, I'd really appreciate it!
I've never had to ask for help before with flashing one of my devices, and have flashed hundreds of times with my previous phones, S3, S5 and Note3 .. However this one has me a bit stumped. I have the Note4 N910F and I see many awesome LP ROMS seem to require that you flash stock 5.0.1 via Odin before flashing the custom ROM.
I managed to do this successfully with the ROM listed at Sammobile called "Unknown 5.0.1 N910FXXU1BOC3 N910FTPD1BOC1" - Everything is OK, boots perfectly and I have cell signal and LTE. Rooting was also a non-issue. The problem I have though is that no matter which custom recovery I try, and regardless of ROM that I try, all seem to get stuck in a boot loop at the Samsung screen.
Am I doing or have done something horribly wrong?
Please help!
I think I may have answered my own question. The stock ROM I flashed was BOB3, it seems I need to be on BOB4, which is the German based ROM. Busy downloading that now!

Why can't you flash custom rom's with BOB3 installed?

New to I337 somewhat confused

New to the I337. AT&T with NC1. Android 4.4.2. Stock ROM with the 3.4.0-1125940 kernel. Rooted, SE Linux permissive, Safestrap installed. Compared to other phones I have owned, rooted and installed custom ROMS for this one is way more complex.
Today I tried to Safestrap flash a couple of different ROM's- the Goole Play edition (jflte GPE) and the Lollipop 5.1 ROM 2015061jflte both times using Safestrap. Neither worked. In the case of the Google Play edition, it wanted to install a new kernel as well, I tried with the recommended kernel on the install GUI (wow an install GUI on Android). Both times stuck in a boot loop. I ended up using for the second time, the excellent information here
http://forum.xda-developers.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642
to get back to stock NC1 (thanks again guut13 for the excellent guide and links to resources) and restored via Safestrap the present stock configuration.
My questions are as follows (I am posting this after a LOT of reading here)
1)Can I use LokiDoki ? I understand it resolves problems with the locked boot loader where one can flash pretty much any S4 ROM on the I337.Is this true?
2) I wanted to give the two ROMS I mentioned today a try. Neither worked although I followed the instructions carefully (wipe, install and reboot). I also would like to try the Phoenix ROM. Is it compatible with Safestrap? Are the two I tried today compatible with Safestrap?
3) I am on 4.4.2. I understand that 4.4.4 is out there as well as 5 but when I check either via Kies or OTA I am told this is the latest firmware for my phone. Any way to update this?
As I said earlier this phone is a lot more complex from a modding standpoint than any other I have experience with. I am unclear on which ROM's will work with the NC1. Before I knew about Safestrap and the boot loader problem I tried installing TWERP and ended up having to rebuild things with guut13's excellent thread.
With NC1 am I stuck on the stock ROM ? Can kernels be updated on NC1 using LokiDoki?
Any light or advice to be shed on my confusion wold be very much appreciated.

Look at this other excellent thread started I by guut13,î answers all.

Loki doki is not an option for you, and you can only install tw based roms.

Thanks for the link. Have seen this thread. So I am on 4.4.2. So can I flash a 5.x ROM on the phone provided its TW --or does the phone have to be updated via OTH or another method to 5.x first? Or am I stuck on the ROMS specifically available on 4.4.2?
Thanks again very much for your interest and the link. Wish I had shopped more carefully and bought a non AT&T phone, one of the 5xxx models but I couldn't find anything other than the AT&T ones here in Ecuador.

That will get you to 5.0.1. You can flash the lollipop roms after that.
I wish I had known more before I bought my phone too. Live and learn, I'm about do for an upgrade though. Good luck.

Again many kind thanks for the help. This is the most complicated chain of BS to go through just to update a ROM thanks to the locked boot loader I have ever seen..... however you and others here deserve a lot of credit for finding workarounds...... the phone has been made needlessly complex with the BL and efforts by Google and AT&T to "protect" their turf and monetise the user. I would upgrade today were I not in Ecuador where everything costs double what it does in the US. The phone thief crop here is thick- this is the fourth phone in 2 years although the Galaxy Grand Prime I bought after the last robbery I still have. Broke the screen on that one and it was repaired improperly, I get a blank white screen on startup so can't get into recovery so its worthless to me for what I want it for..... so I have the S4 AT&T. Ah well.
Many thanks and enough of my *****ing.
