Hey all. I have an at&t GS4 running MF3. I remember when MF3 first came about how everyone was saying it will be impossible to downgrade this firmware. My question is has someone figured out a way to do it yet? I don't understand why this "qfuse?" would stop us from downgrading our devices. My main goal with a downgrade is to be able to install GPE KitKat. I currently have safestrap but i believe it is still limited by not being able to use roms that are not 4.2.2. Hope to get some help soon. Please don't be rude and thank you for your help.
Oh! Also if there is another way to run GPE KitKat on MF3 please let me know! Maybe safestrap can do that now! idk.
Again thanks for all the help.

There is no way yet to downgrade to a lower version with the locked bootloader. The fuse count is stored in the aboot and when flashing in download mode, it checks if the one being written has same or higher count. If not, it will fail the write and hence we wont be able to downgrade.
The locked bootloader puts the restriction on safestrap. We can only successfully boot a ROM that matches the base firmware version. This is because we cannot flash a kernel that doesnt match the bootloader. So, if you are on MF3, you can boot roms that are based on 4.2.2 only.
So basically no one has yet to find a way to boot anything higher than 4.2.2? That sucks :/ oh well then. Will just do gpe 4.2.2 with the Google home app.

I assume since your on MF3 that your in reference to running custom 4.2.2 ROM"s via Safestrap...
You can move up to running custom 4.3 ROM's if you update to the MK2 firmware and use the latest version of Safestrap. This is currently the best option for a non-MDL device. I suggest updating to MK2 and loading a 4.3 ROM like Hyperdrive.
Alternatively, you can upgrade to MK2 and use the Deadly Venom Kitkat Tool to run 4.4 ROM's...
I'd HIGHLY suggest reading this thread...

Hi all,
My Google-fu is failing me and I'm not certain of the best route to take a Galaxy S4 SGH-I337 AT&T 4.2.2 MF3 (Rooted with Motochopper) up to the new AT&T 4.3 firmware.
Can anyone point me in the direction of a guide for doing this? Everything I'm reading seems like I'll have to sacrifice my root, flash to stock with Odin, and then wait for AT&T to re-release the OTA update to 4.3. Am I off base?
Motochopper cannot root MF3. We're you able to hold root when you upgraded and are hoping to keep root again?
At the moment yes you will have to sacrifice root. I did. Root keeper does not support android 4.3 and keeping with SuperSU does not work either.

My phone is still rooted at this moment, though I'm on 4.2.2. I haven't upgraded anything yet. I was hoping there was a custom rom or something I could flash to get to 4.3 and retain root.
I'm just gonna wait until a stock 4.3 rom comes out that supports safestrap so I can keep root

Since you are rooted with a custom recovery you CAN flash 4.3 now without losing root. Just use ShoStock-i MJ9 4.3http://forum.xda-developers.com/showthread.php?t=2468860
Or VisionX MJ9 4.3 http://forum.xda-developers.com/showthread.php?t=2391142
Or Deadly Venom MJ9 4.3 http://forum.xda-developers.com/showthread.php?t=2503692
and POSSIBLY a couple other 4.3 Touchwiz firmwares that are found in the Android Development Section
These are all from he International MJ9 firmwares but to me are better than the ATT firmwares for 4.3. The ATT 4.3 removed the Data Toggle completely from the pulldown menu and now you have to go into settings each time to turn it on or off. Plus other changes that are solely LACKING compared to the international firmwares. I have tried two of the above and they are both great and the third from what I have read works great as well. They are all great devs. Try them out and I suggest using the Jeboo 3.0 kernel for best results.

I only gave the advice above because he said he is ROOTED WITH MOTOCHOPPER ON MF3. As we know MF3 cannot be rooted with motochopper. So I was guessing that he rooted while on MDL or MDB with motochopper and used a ROM to upgrade to MF3.
So unless he is/was mistaken with those comments and he meant to say rooted on MF3 with safestrap then I would of told him to look at the safestrap threads.
Hopefully he clears things up with that as I WON'T want to give him Bad Advice.

well my touch screen has stopped working, so now this phone gets to go back to AT&T for repairs.
whats the best way to remove root and factory default it?
sorry to bump an old thread, but I wanted to see if anything had changed so I could upgrade from my rooted 4.2.2 I337UCUAMF3 to one of the newer OS versions that are out. This phone was a warranty replacement, but I had no trouble rooting it with Motochopper when I got it so I don't think it came stock with MF3, but its been 6 months so I can't say for certain.

You could flash the md3 tar and return it to stock. Then let out update itself. You'll lose root and you'll want to read some of the threads on the general section dealing with mk2 and nb1 before you do so so you know what you're getting in to

sorry if this is an old question.
well im using an sgh i337 at&t,
im in 4.2.2 MF3, it's rooted an using safestrap
my problem is that whenever i try to flash a 4.3 TW rom
(Goldeneye) in another rom slot, it just seems its not working, is not even booting. i also tried flashing an aosp based room. p.a.c or dirty unicorn rooms, same result.
so i just saw a post saying at&t has 4.3 since november 13, i would like to know how to get it. i mean, maybe im doing something wrong with safestrap. what if i try ota upgrading and it briks my phone? i dont even know if 4.3 worths loosing my root, which i dont know if i could achieve to use in 4.3
so resumeing my questions are.
am i missunderstanding safestrap flashing procedures?
is there a root for 4.3?
how can i get 4.3 for my phone? (safestrap room, odin upgrade, ota upgrade)
is there a custom recovery for 4.3?
any help please?
AT&T pulled the 4.3 update to smooth out some "issues." ETA for the re-released update is anyone's guess but will probably happen "soon."
You can only use TouchWiz-based 4.2.2 ROMs on MF3 with Safestrap.
I'd never flash anything more recent than MF3 if you have any desire to ever run custom ROMs or unlock the bootloader. This is pretty much the rule of thumb with any new release with a locked bootloader.
It's a safe assumption each new release from AT&T will only lock this phone down *more.* Unless Samsung comes up with an official bootloader unlock process similar to HTC, it will only get harder to customize the phone after an upgrade.

No Odin tar for 4.3 yet, but search through the 4.3 thread in the General forum and you'll find links and instructions buried in there on sideloading 4.3 via ADB, (if you don't simply want to wait for the OTA). Note that you must have a pretty clean stock phone to get it to work. If you want root, I would suggest rooting MF3 first, then enabling survival mode in SuperSU Pro, as that's the safest way to get root on 4.3. One more thing: no custom ROMs, recovery, anything is available on 4.3, just root.
Currently have a AT&T S4 rooted with MDL firmware. I have flashed other 4.3 loki roms without any problems (using Goldeneye 20 now). From the reading that I have done on the forums, it is my understanding that certain roms require a newer firmware version, for example, Hyperdrive. Is that a correct statement? If so, will that continue to be the trend with later releases? Can anyone provide any additional information to help me understand this better? Thanks in advance!

For MDL, that does not apply. Basically people with MF3+ phones need to upgrade to 4.3 to have 4.3 ROMs. All you need to do is continue to use loki and never upgrade your bootloaders.

Unless he wants a 4.4.2 rom then he needs the new bootloader....which is locked! so stay away of 4.4.2 for now
Flashing roms (unless stated by OP) will not update your bootloader correct? Since I am one of the lucky ones to have the MDL, I don't want to jeopardize it.

Not true, he can flash a 4.4.2 ROM with the MDL bootloader as long as he gets a loki 4.4.2 kernel. Otherwise the 4.4.2 Google Edition thread wouldn't get much attention

Flashing ROMs will not touch your bootloaders. Just never take any OTA updates to the stock ROM, and never ODIN any firmware except MDL. OTA updates on custom ROMs will only work in some cases (GE doesn't because they're ported from a different model, Hyperdrive will because it has a specialized system).

I honestly do not trust the update and I will explain. I believe the update was pushed to prevent us, the custom ROM users, from downgrading back to mf3. We all know that in mf3 there is an exploit where we can change the kernel inside the memory or something like that. I am rooted on nb1 and am running a bootloader that lets me downgrade back to mf3. It would make sense to me that they are trying to prevent that exploit. I know they probably fix a stability issue or something but I would not flash to nc1 if you don't want custom roms here in the near future.

On top of that, the exploit is at the kernel level. We can still get the MK2 kernel so we can still get the exploit. That's why bypasslkm still works on the downgrade.
