Upgrading straight to Lollipop - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Below thread makes it seem like one can directly upgrade to Lollipop regardless of base ROM. I currently have stock 4.4.2.
https://forum.xda-developers.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642

If you have a stock 4.4.2 rom, are you able to update via OTA?

No, I am unfortunately not able to. I have an unlocked ATT phone on TMobile.

Based on this thread, it seems like if I can get to NB1 then I can use Stock Recovery to apply updates.
I am currently on NC1. Can I use Safestrap to install stock NB1? (I am unable to get Odin to work on Windows 10)

It does not look like you can use Safestrap to downgrade from NC1 to NB1 because the guide specifically mentions Odin; therefore, I would follow the guide. It's a bit more complicated to recover the sgh-i337 from a softbrick because of its locked bootloader. I'm in Canada and Canadian carriers have the sgh-i337m which has the same hardware as the American version except the bootloader is not locked.
Have you tried different versions of Odin? I have had great success using Odin 3.07 for my flashing requirements.

I have tried 3.07 and 3.13.1. Let me see if I can install an older version of Windows for it.

Regarding "STEP 2 - Flash Updates in Stock Recovery", can those be done off the internal storage or must they be done off external storage?

I used Odin to flash the base and did all the updates afer that using ADB and worked great!
Thanks @guut13

Try new firmware on S4 without rooting possible?

Hi All,
Am using an i337M S4 from Rogers here in Canada and was wondering if it was possible to use ODIN and try out the new leaked 4.4 firmware. Is rooting required to achieve this?

First you must be certain the leak is for i337m model becuase there is the international version and the US version which are both different from the model you have (I have the same but Telus). Now as far as the files, if they are in .tar format then you can flash via Odin, if thet are .zip then you need a custom recovery to flash them. I know for certain you need to root to go the custom recovery route, I think you need to be rooted to flash they system files in Odin also (which if it is a stock rom you are flashing would loose root following the flash). Depending of the root method you choose be aware also that you may trip the Knox counter also, definately if you install a custom recovery. There a number of 4.4 roms for the i337m already that are not stock and are rooted, you may want to look at these also. Most importantly... before you attempt anything read...read ... read... there are pity falls you can end up in if you don't pay close attention......

Thanks for the reply .. actually I had a S2 before which was rooted and I used many different ROMs on it. I did root the S4 once as well but then lost it when I did the 4.3 update. Since then I never tried to re-root, is there an easy way too root right now for the i337M with 4.3?
If you are on stock unrooted 4.3 you should get official 4.4 update soon.
Also, questions go in the qna section not the development section

If you wait for the update you will likely be waiting longer for a root solution... if you want to root the phone, look up chainfire's CF-auto root for i337m

[Q] HOw to revert back from MK2 (ATT SGS4 i337) to MDB or MDL

HI there,
DOes anyone have a solution for us stuck on MK2?
I have the following problems:
I bought this i337 second hand, and it came with UCUAMK2 firmware.
I rooted it with SAFEROOT (saferoot.zip). That worked fine.
But I cant install LOKI, to get the ClockWorkMod, so I can't install Custom ROMs.
Because when I type in the commands in Android Terminal, to flash loki's CWM recovery, it says :
[+] loki_flash v1.1
[-] Loki aboot version does not match device.
SO i figure, I have to revert back to MDB or MDL firmware.
BUT when I open ODIN, and try to flash the official firmware:
1. I337UCUAMDB_I337ATTAMDB_I337UCUAMDB_HOME.tar.md5
it FAILS in ODIN, so I (try) to flash this:
2.I337UCUAMDL_I337ATTAMDL_I337UCUAMDL_HOME.tar.md5
but that FAILS also!!!!!!!
SO should I install SAFESTRAP?
Some ppl complain, that screws things up, and end up in bootloop, and can't remove this SAFESTRAP...so i dunno if
i should install it.
Does flashing via/using ODIN FAIL==> because my bootloader is LOCKED?
Can you tell me how to Unlock my bootloader????
I need to go back to MDB or MDL, because otherwise I can't unlock the carrier restriction, since I'm on Vodafone,
and not on AT&T!
Plus, I was always installing custom Roms on my S2, S3, and all my other android devices since 2009....sorry to see
that the S4 is
such a headache....
Can you help me out please, seeing how good aof a DEV you are....?
Please and thank you
djmisi
You SOL buddy. Sell the phone and get something else. You will never be able to downgrade

You will need to use safestrap.
Loki does not work with MK2 because they patched it in the MK2 update.
At this point in time the bootloader cannot be unlocked.
el o el
The s4 is nothing like previous samsung devices...at least on att, the bootloader is locked, safestrap is your only option.
Also keep in mind, att stated about a year ago they will no longer be supporting phones with unlocked bootloaders...so the problem you are experiencing now can be expected on every new att branded phone

There is NO WAY back from mk2. You can flash custom roms ONLY with Safestrap. No CWM no TWRP. Read this guide, it has everything you need to know for the S4. There is nearly 30 custom roms tested & affirmed working. Good luck & happy reading.

SGS4 AT&T i337 on Stock MK2...jeboo kernel/recovery needed to install SHOstock v3.0 ?
I am very familiar with custom roms and your kernels, from always using them on my SGS2 i777 (AT&T), but i just bought an SGS4 i337 AT&T, on MK2 baseband, and everybody suggested I should install the SHOstock v3.0 for the i337 (http://forum.xda-developers.com/show....php?t=2305752).
Problem is, I am sooooo confused now, because there is jeboo kernels: (Jeboo_Kernel_i337_v3_0a-i.zip, Jeboo_Kernel_i337_v3_0a.zip, Jeboo_Kernel_i337_v3_0.zip, Jeboo_Kernel_i337_v2_2.zip)
...than there's your RECOVERY: Jeboo_Recovery_v2_1.zip
so Im very confused now how I should go about installing our most awesome DEV shoman94's SHOstock v3.0) ROM...==> THAT I DUNNO WHAT SHOULD I DO ANYMORE.....
1. Because, on the thread there (http://forum.xda-developers.com/show....php?t=2305752), in POST#1 it says , in the Instructions, that :We must be running a custom recovery using Jeboo's Recovery from Post#4 which is your Jeboo_Recovery_v2_1.zip
2. But how should I run the Jeboo_Recovery_v2_1.zip RECOVERY, if Im on SafeStrap 3.71 (which is a recovery also)???
3. If i flash Jeboo_Recovery_v2_1.zip, wont that brick (or softbrick) the S4?
4. Or if I flash Jeboo_Recovery_v2_1.zip, will I end up having 2 recoveries? Or will I only end up with having only the Jeboo_Recovery_v2_1 ???
5. In POST#3, it says that:
IF YOUR PHONE HAS MF3/MK2 BOOTLOADERS, YOU MUST RUN THE MF3/MK2 STOCK KERNEL. DO NOT TRY INSTALLING ANYTHING BELOW UNLESS YOU HAVE MDB/MDL BOOTLOADERS THAT SUPPORT LOKI!!
So, should I NOT flash your Jeboo_Kernel_i337_v2_2.zip , since I am on MK2 stock kernel/baseband/bootloader....?
Check it out: http://i.imgur.com/cNWijKF.png
7. I mean, what is BELOW MF3/MK2 and ABOVE MDB/MDL? Because it also says, that: All binaries posted here will be loki'd (as signified by the .lok extension).
SO, keeping in mind that Im on Stock MK2 , but also Im ROOTED via SAFEROOT.zip (as you can see in the pic above: (http://i.imgur.com/cNWijKF.png) , can someone please tell me if I should flash this SHOstock v3.0, and more speciafically, WHICH, IF ANY of you jeboo kernels and Jeboo Recovery should I use?
Can I bug any of you to tell me the exact steps on how to get this SHOstock 3.0 on my i337, if I'm on MK2, rooted, and safestrap-ed?
ANy help would be much appreciated

You are making it too hard. You need to be on 3.71 Safestrap to flash Sho's 3.0. You must use default (stock) kernel. You can not flash any other kernels period. And no other recoveries. And no 4.4 or aosp roms. I am not on SafeStrap as I have a MDL phone. So, you need to go the SafeStrap thread and read up on flashing a rom on SafeStrap. There are a couple threads on the subject. Read all you can first and make any backup your phone/recovery allows before flashing. Also, do a clean wipe before installing rom. That may be different then a clean wipe on MDL/Custom Recovery, not sure--:good:

Phone came from the Store with MDL, ( I see it on the Original box: SoftWare Ver: UCUAMDL....
The guy I bought it from rooted it, and loki-ed it... how did that OTA come through, I wonder? Once rooted and LOKI-ed...the OTAs shouldn't come through, right?
Sounds like the seller messed up and flashed back to stock. He was probably selling it to cut his losses.

Answer, yes & yes. There is plenty of custom roms for mk2 in the All things mk2 guide. You can also upgrade to 4.4.2 Kit Kat now as well. Forget about MDL cause there's no way to go back to it.

But if he had it LOKI-ed, that means he was just fine on MDL, no need for SafeSTrap, unlocked BL prolly ... he was free to install CM, GPE, AOSP, PACman and all these ROMs....so why flash it back to stock MK2? I mean, cutting his losses....that's funny...I mean, unless the MK2 OTA from AT&T came forced.... WHo knows...
He probably didn't know what he was doing, got stuck, and tried to Odin back to stock. Only he used the mk2 package and not the MDL one.
Stuff like that never surprises me anymore. People don't want to learn/read. Just give me the file so I can flash it.

Just ask for a little help, ...why is that so hard, right?
I've been reading up on all I could, and now that I "kinda" get a better understanding of how things lay with the i337 MK2...I can make a decision to flash, and stay stock...
Problem is, I have been flashing since 2009, so I can't imagine owning a droid, AND NOT FLASH IT!!! IT KINDA DEFEATS THE PURPOSE OF OWNING AN ANDROID, right? hehehe
I know that feeling. At least Safestrap is a decent option. I rushed out to grab my MDL 32gb one before they updated their stock.

[Q] Rooting S4 (Build No. NC1)

I am new to flashing so sorry if I have asked some stupid questions.
I have SGH-I337 (ATT) and would like to root and then maybe install Cyanogenmod or any other custom ROM.
Device Details:
Baseband - NC1
Build No. - NC1
Android Version - 4.4.2
I tried to root NC1 directly using motochopper. Then I read and I am now trying to downgrade.
I have got ODIN 3.09 but it does not say support to I337. I have gone through Noob Helper
I have downloaded all zips from Downgrade
After reading the article of Modems; I got confused about my bootloader.
I also have gone through the thread but after that confusion, I did not proceed ahead.
Could anyone please help me?
How to identify boot-loader?
Which ODIN to use or do I need to use SAFETRAP (not sure if bootloader is MF3) ?

Dont worry about Odin saying the device is i9505 or so. The flash will work.
For samsung phones running full stock firmware, all the components have the same version. Since your build is NC1, your bootloader is also NC1.
You are in the right track. Follow the downgrade thread to partial downgrade to MK2. Then use saferoot to root. Then install safestrap v3.72. Then use the deadly venom kitkat magic tool to install any kitkat rom of your choice from this list (post 3).
You cannot install any AOSP based rom. So, no CM. Even google play edition roms dont work.
You can install AOSP themed roms (like BlackBox3.0)

Thank you for the response. I have downgraded to MK2 and have done the root.
I was wondering if you could tell me if it is possible to install Liquid Smooth ROM. I have seen the video and I have downloaded from here which says S4 unified. Also, there are some videos claiming CM on S4.
Could anyone please help on the same?

As already stated, no AOSP based roms will work (ROMs that are built by compiling AOSP code). Only TouchWiz based roms will work. If you need AOSP look and feel, you can install an AOSP themed rom.
CM/AOSP on ATT S4 is only possible if you have the MDB/MDL bootloader. Anything above that, it wont work.

Sorry for the repeated questions.
I tried to update through Safestrap with BlackBox. But I got stuck on the boot screen where it shows Samsung Logo. I might have done something wrong. I just clicked next on BlackBox 3.0. Could anyone please help me !
Edit:
When I tried to reboot into recovery mood (Vol Up + Home + Power) it says:
" Secure Fail Kernel
(Warning Sign) System Software not authorised by ATT has been found on your phone"
Don't select the reboot now option in the aroma installer at the end. Then, after the ROM flash is complete and before you reboot the phone, you need to put the phone back in download mode and flash the MLD ap/bl/cp files from the tool

I flashed the NB1 using ODIN but it still stays on Samsung Logo with custom logo. I am not able to navigate any where else from that screen.
Edit:
I was able to go into system recovery. Please let me know if I can fix the error somehow.
Thanks a lot !
Get into stock recovery and factory reset. I am not sure why you flashed NB1 though, as there is no direct root method for it yet

He probably was following the steps that were provided elsewhere here that had you go from nc1 to nb1 then back to the M (I can't remember which M) one.

Get into stock recovery and factory reset. I am not sure why you flashed NB1 though, as there is no direct root method for it yet

I had rooted MK2 and the installed the custom ROM (Blackbox) and then was suppose to flash NB1.
So, if I just did a factory reset it would solve my error?
Thanks for the help!
Edit:
I tried doing the factory reset. It just wipes all the user data. And I am still stuck on the same screen with Samsung and the custom logo.

[Q] Upgrade SGH I337 to Andriod kitkat

Hello,
I have samsung SGH I337 phone and its not rooted. I bought this phone in Sep 13 and unlocked with some code. Currently its stuck at 4.2.2. and I want to upgrade the phone to latest 4.4.* . As I unlocked the phone, this stopped getting update from ATT and dont show any available updates.
Can someone share the process to upgrade to latest kitkat ?
First, if you're on mdb or mdl firmware you might want to reconsider upgrading. If you are you have the ability to use twrp or cwm custom recoveries and easily flash roms
But if you still want to go ahead and update then flash the nb1 tar file in Odin http://forum.xda-developers.com/showthread.php?p=50912149
This will wipe your device so backup anything on your internal sdcard. You will not lose the sim unlock.

My S4 build number is JDQ39.I337UCUAMDL.
Forgive my ignorance but can you tell me what is the significance of mdb or mdl firmware. Also does upgrading the Android would create any issues on my phone.
Need one more information on Kitkat version i.e. which kitkat version is stable and has no issues.

You're on mdl firmware. There are users here who would love to be on that firmware version. Being on mdl allows you to run custom recoveries. With newer firmware you can only use safestrap as a custom recovery which limits what you can flash.
Edit, once you go to nb1 firmware you will not be able to go back to mdl.
But you said you're not rooted and have not run custom recoveries. So if that is not important to you then flashing the nb1 firmware will up grade you to 4.4.2 kk.

If you upgrade to 4.4.4, and want to flash custom roms you'll have to use safe strap. If you keep 4.2.2 you can flash 4.4 roms also. I wouldn't recommend updating, but it's your choice.

Help with Rooting

Helping out a friend with an S4 with on NB1. Phone has been sitting for a while. He wants me to set it up with a custom rom or at least root it. Have dabbled with the Verizon S4 but never with the AT&T version.
Can the bootloader be unlocked on NB1?
If not, an you go back to an older release to unlock the bootloader?
Is there a prefered root method for NB1?
Is there any benefit in staying with Nb1 vs taking the OTA?
Thanks

The bootloader stlll cannot be unlocked on ATT S4. We still have a working recovery "safestrap". Safestrap doesnt replace existing stock recovery but is available during normal boot mode through a splash screen on bootup. Use safestrap version 3.72 or 3.75 and flash into stock slot itself. In case of issues, the phone can be recovered by Odin flashing the full NB1 firmware.
NB1 is not rootable. The next version NC1 is rootable with "towelroot". The latest NI1 is not directly rootable but can be rooted by Odin flashing the NC1 kernel.
You can manually update to NC1 and root.
There are a large number of ROMS that can be flashed on I337 including google play edition ones. AOSP/AOKP roms dont work though.

So the easiest would be to Odin to a stock NC1 and you towelroot.
Any links to the stock NC1?
Thanks

We do not have odin file for both NC1 and NI1. There is an update file that can be used with "adb sideload" to update your phone. How to update to NC1 is there in the link I provided.

I tried towelroot to see if it works. It worked without a hitch. So I guesss the newest version works with NB1.
Thanks
