I have not. Havent had a lot of luck flashing roms on the s4. I might try sooner or later. Just tired of getting error messages and having to restore. I am rooted with motorchopper.

We don't even know if OP is on MF3. A suggestion like that could result in a brick.

Correct me if I'm wrong, but if he's on MF3 he has root, but no recovery, so he wouldn't be able to even flash a Rom to brick it

He could try to flash a recovery though to try to flash a rom and then he'd be sol.

Trying to flash a recovery would result in a brick...

Im on mdl and have a twrp from the motorchopper tool. Other than that im stock. Is there a tut on how to flash a tmobile stock rom to an att variant? I downloaded the rom already and was wanting to read into it more before flashing.

There is no way you checked out those links that quick. And if you did, you would have clearly seen the answer to your question. Take some responsibility for your device. I have told you EXACTLY where to look for what you need, it is up to you to take the time to read and learn about it.

I read the entire post there was hardly any mention of the i337 mainly the m919 it says flash your kernel but which is that since I am flashing a tmobile rom on a att phone using tmobile service.

I'd you're wanting to remain rooted, then you will need a custom recovery.

I used to be on stock recovery rooted and was able to update ota while keeping root with ota rootkeeper... And stock recovery

Every rot method I've seen requires installing a custom recovery. Either twrp or cwm.

It's possible to extract the stock recovery from the Odin image and flash it independently. Check it out in this post. Be warned that it's only for AT&T S4's and it's possible to brick your device pretty badly if you flash the recovery to the wrong place.

yes, you will have to use the odin, and then root again. unless you're running a custom rom, then you will have to full wipe your device.

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.
Sent from my SAMSUNG-SGH-I337 using xda premium
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.

How are you wiping the cache partition? Custom recoveries and ROMs can not be used on AT&T MF3.
this is a known issue with stock recovery on all S4's. some users have no issue with the recovery on one version and then this exact issue after a software update. i'd do some more research to see what your options are.
Yeah that's what I would like to know lol.

[Q] How can I flash Cyanogen?

I have an S4 running 4.2.2 and it's currently rooted. But the root does not allow me to have a custom recovery. I want to be able to flash Cyanogen, but I'm not able to at the current time. What is your best idea of what I should do?

Then reread the OP and make sure you do exactly what it states.
Take your time and just make sure to follow each step.
MF3 can be rooted and de bloated but has no real custom recovery.
Safe strap only allows one on 4.3 to flash 4.2 2 roms.

I'm on 4.2.2 and I followed all the instructions very carefully, but whenever I try to load my slot with the Google edition ROM (4.2.2) the phone goes into a continuous boot loop. I have no idea what is wrong and I can't find a solution anywhere.

make sure you partition your slot big enough...try 2 and 1.5 for data...
I did this and it still didn't work. Where is the best guide on how to exactly flash a ROM? I've been following a video guide on it, but it doesn't work.

You are probably using the wrong GE ROM... Only certain ones work. Check the OP of the SS QA thread.

Can I use a att rom on tmobile Gs4

Sent from my SGH-M919 using xda app-developers app
I wouldn't. I accidentally flashed a NOTE 2 rom on my ATT GS4 and it HARD bricked it. Had to send it in for JTAG repair.
I run tmo roms on my s4. "would think" other way would work. you will need to flash your carrier kernel correctly
nandroid first

As long as you flash a TMO kernel after, you shouldn't have an issue. ATT will typically have more bloat.
You can do some more reading in the dev threads. Try the ViSiON-X thread. Have had good luck with that ROM.
