Could you reboot it two more times to verify it still uses that boot screen? Sometimes you gotta reboot with the revalidated binary.

You need to go to the "General" section and read the threads that already exist about the OTA... your questions are already answered in them. Good luck.
Basically, if you took the OTA, kies is your only hope to get back to AMDL firmware right now. If kies doesn't work, you are SOL. But, like I said, all of this has already been discussed in the other threads.

Mdl vs. Mf3???

Hey guys i just got my s4 yesterday and am wondering what the difference between the 2 firmwares is. Is one better then the other? My phone downloaded an update last nite but I havent installed it yet. Was going to root this afternoon.

MF3 locks the boot loader, so if you want to flash ROMS, don't update. It also has some software tweaks and adds Knox and the ability to easily store apps on SD card. There is a root, but not a boot loader unlock, yet.

Do yourself a favor and search and read through the first page or so of the general and Q&A sub forums. The information you need is there, especially the "pinned" threads in the general section. Read the "software update" thread and the "new root method for MF3" thread also. Good luck.

Will do scott thanks! Im coming from an iphone and forgot how big the android world is! Had an inspire 4g prior to my 4s

Some say it has auto installed

It will auto install. You should root and put a custom Rom on asap. Check your firmware first though, if it's already installed you can brick your phone trying to root the way you would with mdl. If it's mf3 you've got the update and you'll have to use a different method.

I had Knox on MDL, not sure what your talking about.
Mf3 locks the boot loader but fixes bugs and make the camera take sharper pictures. Plus better cell signal.

I got lucky. It tried to auto instal so i yanked the battery and quickly rooted and threw a custom rom on it.

S4 Updates, Flashing...

Hello,
I have been trying to figure out a few things with the S4 and read a lot of stuff but I have a few unanswered question.
I come from using NExus phones since Nexus 1. Unlock Phone, install CWM and then use it to flash roms or rooting scripts.
Now, I have S4. I am still with their STOCK on I337M (Canadian Model) and I rooted using CF-Auto-Root and ODIN.
What I don't understand, is:
- Can I flash CWM and then just use CWM and SuperSU-vx.xx.zip to root? Why Use Odin?
- Now that I am rooted, if I new SAMSUNG firmware comes along, I am assuming it will fail, I will have to unroot and then apply firmware and then root again? How do I unroot? "Full Unroot" from the option in the app just like the Nexus phones?
- S4 has a counter from what I read, but lot's of warning about bricking phone is that only active on Samsung stock? What if I flash a google stock?
- Can I just use Rom Manager Pro as I used to with Nexus devices...
if I flash CWM, is it replacing ODIN? Is odin a recovery like Odin! If anyone can point out and explain the difference between CWM , ODIN, Nexus phones and S4 it would be great...
I know that now when I go to download mode (Is that like fastboot?) it shows binary as being custom, but I don't get a yellow triangle when I boot...
Thanks for any info regarding explaining what ODIN is...
I also noticed although I have 16GB phone, 6.38GB is system! That is huge! Is that normal?
There are some nice features that I would not like to lose, so I stuck with samsung and just use NOVA home screen...

This is actually the "ATT Galaxy S4Active" forum. S4 forum will have answers to all your S4 questions.

I just went through the un root because I was only using it for one thing. I ended up flashing the original ROM using Odin then doing a factory reset and cache wipe. Now waiting for the update not sure I will root until S4 is not longer updated by Samsung.

Hi,
Look HERE
OTA will remove root,and the latest will lock down your bootloader.

Hi
I have AMG1... I think this is the latest one but I was able to root.. Will locking boot loader prevent rooting.. Could it be another one for at only?
Thanks
Note: yes. I did notice chainfires note.. But he doesn't say what load is the latest.. There are so many Samsung s4 models devices.. Each with different models its so confusing

I just installed CWM on latest version of Canadian I337M AMG1... Its good so far.
Xda modder.. There are differences between i337 att and Canadian i337m.. No forum specific to the Canadian folks?
Thanks...

Just a quick Root question

I was pretty big into XDA under my Original Note
I now have AT&T S4 and would like to root it.
Is there a way to root the S4 without a PC?
I would like to use TWRP I have goo installed but it wont root my device from Goo so was just curious.
I did browse the forums really didn't find this so I am posting it
Many thanks

What firmware are you on?

You need a PC to format the card, the rest you can do from Terminal Emulator: http://forum.xda-developers.com/showthread.php?t=2387577
If you browsed the forums you would know that you cant install a custom recovery on an S4 running MF3 firmware. Meaning no TWRP or CWR. But you can root with the above method.

I did look so your saying no matter what cdm and twrp cannot be on s4. Thats fkd if so

Do yourself a favor and look harder. There is a lot of information available about this and you WILL brick your phone if you don't take the time to read and learn about it. Good luck.

Look man I looked I will look again. But I have only bricked my phone once back when first Google phone came out not a noob. Just didn't want to spend hours looking if it took someone 30 sec to respond. Admin please close my thread due to lack of assistance will look elsewhere thanks

Do you have a PC? The VZW installation software has a repair function as well and will completely wipe and reinstall latest stock version. Took me about 20 mins or so to do when I botched a root attempt. Hope this helps

Does not work with custom roms/safestrap installed.
Nobody else has help? I am surprised a community as large as this one has no help.

You will need to remove SS completely and it should work after that. Strange it didn't work for you. Have you tried the emergency recovery in kies3?

Have you tried this one? And this should be in the Q&A section.
