Galaxy S4 CyanogenMod - Galaxy S 4 Q&A, Help & Troubleshooting

Hi,
Im having fast battery drain issue with my AT&T S4, I read on forums that by installing Cyanogenmod can improve battery performance. Now before installing Cyanogenmod I would like to ask some questions.
1. Will I be able to go back to stock from Cyanogenmod ?
2. Which version of Cyanogenmod should I download ? I think v11 gives better battery result.
3. Will this completely uninstall all bloatware from samsung and at&t
4. Will I get more Internal space ? Currently I have 9 gb out of 16 gb
Also I have rooted by mobile using this Guide
Phone Specification
AT&T S4 SGH I337
BOOTLOADER : I337UCUFNJ4
PDA : I337UCUFNJ4
CSC : I337ATTFNJ4
BASEBAND : I337UCUFNJ4
KERVEL VER : 3.4.0-2960651
ANDROID : 4.4.4

Thanks

You will also need a custom recovery in order to flash a custom rom.
You should be able to return back to stock rom with Odin.
Yes, flashing a custom rom will remove all Samsung and AT&T apps from the phone.
No, you will not get more internal storage. 9GB user space is all you get with the S4.
Regarding your battery drains. Make sure the battery is still good. If it is swollen you should consider getting a new battery.

Thank you for your reply.
Could you please elaborate the first line. How do I know if I have custom recovery ?

You would've known if you had one because custom recoveries are usually flashed by the user. Since you don't recall flashing any then you don't have one (custom one).
Unless it was part of that tutorial and you flashed it unknowingly
Problem is, your phone has a locked bootloader. This makes the whole process more complicated.

The tutorial I followed to gain root access was like flashing nc1 kernel than use towel root and than flashing back to nj4 kernel. This is what I did to gain root access.
Now can I install cynagenmod in my mobile. If not than is there any extra step I need to perform to install cynagenmod ?
Thanks

Yes. I told you that it requires a custom recovery in order to flash a custom rom to your phone.
Normally flashing a custom recovery is simple. But since your phone is an AT&T model, it has a locked bootloader.
Download and follow the instructions from here.
Good luck.
You should note that this may not work on your device due to the locked bootloader. Then you will have to find another method.

[Q] i9505 4.4.2 update + root

I'm currently using 4.3 android and there's no official 4.4 update yet. What I want to do is upgrade to 4.4.2, then root it. I looked for solutions but they all seem dangerous to me, a beginner.
Cf auto root says that if my bootloader is locked, I risk bricking the device. How do I check if it's locked or not?
How can I backup everything so that IF something goes wrong I can go back to stock?
Where can I get the CORRECT firmware / android version 4.4.2 for the i9505?
My baseband number is XXUEMK9 and the phone is factory unlocked. I basically need to be spoonfed with baby explanations if possible.

Hi there,
4.4 update came out a few days ago.......There are plenty of links around to download and flash via odin....THIS is just one of them.
If you are looking at flashing custom ROMS then root is generally not necessary as most custom ROMS will root your device. Only a custom recovery is needed. Philz and TWRP are the most popular. A search in xda will help you find them.
I encourage you to do ALOT more reading and research before doing anything unfamiliar to your device as only you are responsible for it!!

[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] Koodo S4 upgrade questions

Hello Gurus,
I have the Canadian S4 (I337MVLUFNI2) running stock 4.4.2. I've just downloaded the Lollipop upgrade from Koodo but did not install.
I'm looking to root and flash CM12 or other ROMs, but I'd like to try Lollipop first.
Few questions about the upgrade:
-Will I be able to root the device after upgrading to Lollipop?
-If I don't like Lolipop, can I revert to my 4.2.2 using my Kies back up ?
-If I want to be able to evert, do you recommend that I root my 4.4.2 and take a nandroid back up first ?
(Battery life is important for me. If the upgrade turns out to be disastrous as some online reports indicates, I'd like to be able to go back to 4.2.2).
-What is the recommended way to root and install recovery for my device ?
Thanks to all..
Do what I did.
Backup all files to PC
Flash lollipop firmware through Odin which you can download from sammobile
Reboot into recovery and wipe data and cache(this will erase everything on phone)
Boot up phone and setup accounts
Then once finished flash this through odin http://forum.xda-developers.com/showthread.php?t=2293800
Flash twrp through odin
Boot up and copy files back to phone
Reboot into recovery and flash cm12 or whatever you want
So far, there is not a root method for Lollipop on the S4, nor does Xposed work for it yet (lots of issues with the way Samsung implemented ART to Touchwiz).
There is a keep root method in the S4 general Forum, which is just a way to keep root throughout the install of lollipop if you are already rooted on the current ROM you're upgrading from. I'm on my phone though so apologies for not linking it.
I'm not certain if a kies backup will restore after the upgrade, but even though the keep root method removes safestrap functionality, there is a way to get it working temporarily, which may provide some hope.
Seeing as you're using a Canadian model I don't think you need safestrap, and seeing as I do (AT&T model), I can't tell you how other recoveries will handle the situation.

Hey Zehlek, I'm coming from CM11 (details below). I'm trying to move to CM12 because CM11 is doing strange things with my GPS. Which version would you recommend that is stable for the SGH-I337M? I read the CM12 dev page, but I'm a little nervous about the whole "editing scripts" part of the process.
Current Software -
SGH-I337M
CWM v6.0.5.1
CM v11-20141112-snapshot-m12-jflte

New around here. Some doubts.

Hello.
Ever since I bought a Galaxy Nexus and found XDA, my life changed. Without noticing I got infected a virus: addiction to Android.
My Nexus got outdated quickly and now is pretty done and I need a new toy. 3,5 years later I finally got some spare money to buy a new phone. Since here in Portugal the minimum wage is around 500€ and top flagship phones cost around 700€ (and there's no affordable contract to get something cheaper and still nice), I had to wait until now to get a used Note 3 for 300€.
I love the phone's design and above all the specs. There's no other phone with 3GB RAM and Snap 800 for this price and I always liked big sized phones.
Well, I write too much unnecessary info... I need to stop
Let's get down to the point. I will get the phone tomorrow!!
TL;DR
How do I check the bootloader version? I want to flash TWRP right away and maybe install a Note4/5 port or something stock Android, do I need to be careful with the bootloader?
I know from other phones (i.e LG G2) that any custom rom uses KK bootloader and the stock roms use their respective version bootloader. Is this also true for the Note?
Also, which version of TWRP should I flash? Does it depend on the stock rom version that I have?
Checking if the device has 2.3x GB of available RAM, if Odin and Recovery have their stock aspect and if the S-Pen works is enough to ensure that the Note I'm getting is truly original?
Well, that's all. I'm sorry if I'm asking the same questions everyone does. I'm used to Nexus so I'm afraid of bricking the Note with dumb moves. That's why I am taking my time to read every important thread and asking here some doubts that went into my mind while doing the required reading. I have no warranty (no box nor invoice) so I can't afford to mess up with the new babe
Cheers!
This app!

this app will help you confirm your phone.
then you can proceed flashing twrp and supersu, things are so easy for N9005
and Welcome Aboard
Install phone info samsung from playstore. It could tell a lot about your phone.
To make it easy as long as the phone is running with android version 4.4.2 and above you should use twrp 4.4. If 4.3 use the right one for 4.3.
Sent from my SM-G925F
White Note3 do you have? There are several versions made by Samsung.
Regardless of the bootloader on the phone, I recommend using the latest TWRP as the latest TWRP can be used to flash all ROMs and zip files. Find your device from here: https://twrp.me/Devices/
Before moving to custom ROMs, I also recommend installing the latest bootlloader and ROM.
Not sure if your phone still has warranty but if it does, I would not change the ROM or root because doing either may trip the knox counter and void the warranty.

Thanks! I'm pretty sure it has 4.4.x or lollipop. Should I update to any of those versions (just in case it comes with 4.3) first and then install TWRP?

The phone doesn't come with box nor invoice so I don't have any warranty xd
What is the number or version of the latest bootloader?
What is the model # of the phone? There is the n-900t, n9005, n-900w8, etc.
N9005, it's the european unlocked version
The model # is important when asking questions because the AT&T version of the note 3 has a locked bootloader so it's more complicated to flash custom recovery and to get root.
If you want to run custom ROMs, I recommend upgrading to the latest modem and bootloader, install a custom recovery, back up your stock ROM, and try some custom ROMs to see which one you like.
Look for the tar version of TWRP for your phone from here: https://twrp.me/Devices/
You can flash TWRP with Odin.

So, by upgrading to the latest official rom avaiable I'll have the most recent modem and bootloader, right?
Do I need to follow the order you mentioned: modem->bootloader->recovery->backup->croms or can I flash TWRP, backup every partition, flash most recent modem and bootloader (not sure if I can flash a bootloader) and then install croms?
No, only flashing a newer custom ROM won't update your Bootloader and Modem. You will need to flash those files separately via Odin. Then you can flash the custom ROM you want. The order is simple. Get a custom recovery first, TWRP. Then update your Modem and Bootloader. Then wipe the device from TWRP (full wipe, take backup beforehand if you need) and flash the custom ROM of your choice.
Safest way to upgrade the modem and bootloader is via ota update on a completely stock unrooted rom with stock recovery. After the phone is running the latest rom, then start with customization.

I have the phone and managed to update it to 5.0 -> n9005xxugboa1

I'm from Portugal but the phone is unlocked (no carrier) and they only have firmware for carrier notes... Which one should I download and flash?
Also... with a G2 I flashed a .kdz file (official rom) and ended up with a bricked phone (later fixed via warranty), but I have no warranty in this phone, how can I make sure that the file is safe?
Just check for software updates from your phone.

It says the phone is already at the latest version. I've cleaned framework services and checked again but got the same result.
Try removing the SIM card and moving the date ahead by two days, then try again.

Done that, no update avaiable. Connected to Kies3, no update avaiable.
Is it really in a old version? It's 5.0. Do I really need the latest version to start flashing a recovery?
Also, can I use the recovery without flashing it? I want to check if it works nicely before flashing if it is possible. TWRP can be used to flash any rom right? I'm interested in trying darklord first.
Yes, you can flash recovery without updating. I suggested updating because the update probably deals with the stage fright bug.

Confused over installing recoveries

I can't seem to find a straight answer to my question since most of the info for the S4 is 2 or 3 years old now.
So I have a completely stock ATT i337 running Android 5.0.1. I would like to install a custom ROM, so I understand I need to install CWM or TWRP first. So my question is this... Do I need to root my phone first before I can install either recovery? If so, what method do I need to follow for my version of Android?
I understand that with time there are improvements. Some stuff I've read makes it sound like there is a lot of automation in installing custom recoveries, and maybe I don't need to root first because they root for me.
Thanks.

I think you posted in the wrong forum.
Anyway, if your phone is SGH-i337 and you do not have an older bootloader (MDL/MDB) then you can not install CWM or TWRP since your bootloader is locked.
For the AT&T S4 you have very limited options.
You can find how to root, how to update information here.
You can find how to install custom rom on AT&T S4 here.
