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.

Can somebody tell me about this locked MF3 issue?

I just bought a galaxy s 4 off craigslist and its on the MF3 baseband. Does this stop me from flashing ROMs? What do I need to do to fix this?

I would start by checking out post #2 in my I337 guide.

I was actually just reading that over, but I'm still a tad confused about what ROM this is on. I have a splash screen when I boot that says "samsung" but below it says "custom" with an unlocked lock, and the rom is JDQ39.I337UCUAMF3, which makes me think that dude unlocked the bootloader and flashed a custom (leaked?) version of MF3. Still searching around to find if thats actually the case of not
Thank you for making this guide

Android 4.3 Touchwiz ROM ANYONE??

Does anyone know of a new Android 4.3 Touchwiz ROM? 4.3 has recently been released on the GT-I9505 and I have been wondering if anyone has implemented this into their ROMs yet. I'll probably just flash a Loki patch if it isn't already loki'd.
Anyone have a suggestion or idea? Comment below!

I have already tried flashing the VisionX II on my ATT MF3 S4 with no luck. ROM tries to flash and returns success but progress bar never fills. I flashed the Knootz kernel with no help there either. Upon re-boot, phone passes thru Safestrap and then black screen and goes no further. Like to know if anyone has been able to flash the new VisionX v4.3 and what I did wrong if anything.

Did you flash a loki patch? Remember that it's made for the I9505 and not the I337
Sent from my GT-I9505 using XDA Premium 4 mobile app

You don't need to flash loki if you flash the att ktoonz kernel. I did not use safe strap so I cannot answer that question but with twrp I was able to successfully flash vision I I. This rom is amazing and really fast. If you can I suggest you give it a shot.
Sent from my GT-I9505 using xda app-developers app

I've done so, but with Philz touch. It didn't work though, as it just gave me a black screen after it booted, and then otherwise just kept rebooting without even continuing with a boot animation. I did flash Loki doki, but do you think it would make a difference if I were to flash the AT&T kernel itself?
Sent from my GT-I9505G using XDA Premium 4 mobile app

All I did was factory reset then flashed the rom and then flashed the ktoonz att kernel. Then wiped cache and dalvik and rebooted. Works perfectly...you don't need to mess with loki if you flash an att kernel as they already have it.

Ah yeah. I've actually done so before I read this message and I have it running on my phone right now. I want to get mobile data to work though, and so far it's not going anywhere. I've even given it the right APN, but I guess it's just not showing up when I turn it on. Have you had problems/solutions towards this?

Yes I have mobile data to work. I entered the right apn (ATT PHONE) and then saved it. Also I changed the network mode to lte/wcdma/gsm. I've heard the new audism 4.3 kernel works very well but I have yet to have a problem with ktoonz and have amazing battery life.

Firstly, start here... http://forum.xda-developers.com/showpost.php?p=42320414&postcount=2
The fact that your are running the MF3 bootloader will prevent you from flashing any custom kernels due to the blown qFuse. Your only option as of right now is to root your device either using Kingo or jortex's root exploit. From their your need to install Hashcode's Safestrap Recovery and go from there with TouchWiz based ROM's for MF3.

Thats correct no custom kernels witch means no overclocking,I think with rom toolbox you can change the voltages.

just asking to see if there's any last hope for it but whats LOKI? ive heard about it in the past. Ive seen on KT's Kernel thread it would work on TW but im guessing it wont work for me being the qfuse issue.
Also if none of these are an option whats the point anymore to root? my old S3 was amazing and i loved flashing new things on it but it seems so locked down now to where the only real benefit of rooting is bloatware removal.

There is a lot of information about "LOKI" and "Rooting" in the General, Development, and Original Development sections.

This phone frustrates the **** out of me. So its rooted and all that with safestrap and when I flash a TW rom all it says is go to slot one and ceeate that and wipe the phone and install and when I do that and reboot all I get os a black screen with a blue led at the top

Use the MF3 Odin files, go back to stock and try again. Are you positive you didn't accidentally flash your TouchWiz ROM to the stock slot? Also... was what ROM was it?

I tried StockUp MJ6 4.3 TW rom. When id flash id do tue wipe it says in the instructions and then go and create rom slot 1 and install to that and then reboot to no avail. Ill have to try the stock ODIN when I get home

You need to use the 4.2, not 4.3 in ss.

Im hoping Flight5 4.2.2 TW will work ill try it when I get home. It saying I can flash a LOKId version of KTs kernel I didnt think that was possible on MF3

Which roms did you try to flash exactly? You said you flashed through TWRP, you mean safestap? TWRP outside of Safestrap will not work. You need to provide more details if you really want people to be able to help you. Our S4 is not like the phones we had before with unlocked boot loaders. This thing is a pain in the ass, but thanks the great knowledge & efforts of the developers here, we have so many options to flash custom roms

Yes this is much different than my other phones. I tried deadly venom 139, vision x, and hyperdrive. Yes I rebooted to recovery through safestrap

Well I suggest the following. Start over. Use a different computer, use a different usb cable, & then download fresh drivers, Safestrap, rom. & mk2 modules. Who knows, but maybe the downloads you got are bad. Stick with the At&t versions as they tend to go easier. Also don't let experience guide you. Instead, follow the developers instructions. I've lost count how many times I've flashed my Skyrocket but I know how many times I've flashed my S4 cause damn boot loader has me on pins & needles every time. Well not so much since we have the mk2 tar files. Good luck & please post your results.

OK thanks ill give this a go. Might take me some time to get to a different computer and post results.
