[Q] Need a nudge in the right direction... - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I recently moved back to android from the ios scene and need a little assistance. After setting up and using mhl in my vehicle I see that the max charge rate is limited to 500ma while data is being used unless a custom kernel with fast charge is flashed. I'm rooted on an AT&T s4 on 4.2.2 with MF3 baseband. My main focus is to obtain the fast charge capability, so what is the best way to attack this? After 3 hours of researching I'm still at a loss.
Thank you.

Since you have MF3, you cannot flash custom kernels due to the locked bootloader

Very confused about MF3

I just bought the HTC One for $200, but then I saw that Best Buy had the Samsung Galaxy s4 on sale for $50. I did not know which one I wanted and was truly torn between the two and ended up buying the HTC but if I can save $150 I will gladly get the s4. My only problem is that as I've been reading up on cs4 forums to make sure that I would be able to unlock root and flash custom roms I had came across what seems to be the problem with an AT&T firmware update known as mf3. If I cannot root and flash custom kernels and roms I do not think I will take advantage of the offer from Best Buy. My problem is that even after all the reading I cannot figure out whether it is possible to root and flash custom ROMs and kernels to the new version from AT&T, known as mf3, or if it is still not possible, or if it will be possible very soon so that I'm may use Android 4.4 Kit Kat on the phone or any custom Rom I wish. Can someone please clarify this for me as soon as possible because my time to return the HTC One to AT&T is coming close to its end?

You can root and flash some roms using safestrap. But it's very limited. Imo I'd stay away from the s4
It's there any progress toward cracking MF3? I've had a one x for pat year and kinda wanted a change and I love the screen on the s4. If you had to choose between the s4 and the HTC one taking into consideration the mf3 problem, which would you choose? And which would you choose if there was no mf3 problem?

If you can find a S4 with MDL or earlier firmware it's a excellent phone. Personally if it has MF3 or later I wouldn't bother. But that's just my opinion.
You might as well get rid of the One as well. It's just as locked down.

Untrue, about HTCone being just as locked down. It can have it's boatload unlocked quiet easily and if you want to, although it's not necessary, you can even do s-off to get full unbridled access. I previously had a HTC one x and also from everything I've read it seems AT&T went out of there way to lock down s4 tight , just like they did to the one x but eventually the devs got it. I do want the s4 though,even though this phone is awesome(HTC One), and I can live with no custom Rom for a while but I can't go without root. So if I get a s4 with mf3 will it still be able to be rooted ? I've read up on it but don't understand what everyone is talking about when they say if the phone is encrypted or notand it seems to be random.

So sick and tired of reading about MF3, or MK2 constantly on these forums. If you want to buy an S4 on AT&T look for an MDL one on eBay. It's not that hard, really.
Or buy the T-Mobile variant or International version.
Thanks for your kind response to my honest question mattmjb0188. I can't get a t mobile or international variant bc I'm on a budget. I will use my upgrade to get the phone at best buy for $50, and the condition of this price is that it must be a contract renewal/upgrade, which is another reason I can't get diff version of the phone. Did you even read the op? I would love to get one brand new out of the box with mdl but the odds of that are slim hence why I asked the question in the 1st place. So if you can't help or don't like the question then don't respond, but I do thank you for your info about the other variants that don't have issues, it just doesn't help me.

Anyone new on these forums just asks over and over about MF3 and the Android 4.3 update. Basically, if you get an S4 with Mf3 or later firmware, you are pretty much stuck on stock. Then we have noobs who don't read and attempt to root their MF3 phones and brick them.
On pure stock, the S4 is a bad phone. The software is very laggy and needs a lot of improvement. I was one of the early adapters when it first came out. The phone was a nightmare with MDB and MDL firmware. Mf3 made slight improvements, but not enough.
I would not even invest in buying this phone right now. Most development for it has died down because of the restrictions. Developers are moving on. Those of us with MDL firmware (like myself) won't see much continued support for Loki nowadays anyway. If the bootloader could be unlocked, I believe it would have been unlocked by now. All these workarounds are very limited, and dangerous.
Personally, I wouldn't even buy the phone at this point. Scrape the funds together for either the T-Mobile S4 or Note 3.
Get the nexus 5, you'll be very happy
Thank you very much for that answer, that was an excellent answer. Although I'm not a noob bc I've been doing this stuff for years and been a member for years.I did the trading but I am not familiar with Samsung at all bc the last Samsung I had was a captivate. It's there a lot of active development for the t mobile variant? I'm guessing it's probably around $600, right? Lastly do you think that there will be a solution to the lock down of mf3 and later in the next few months?
Again thanks for your very helpful answer.

The development for the AT&T S4 has died down. In my opinion, no one will ever unlock the bootloader for it. Maybe someday with some future device, but not this device. The closest we got was with the loki method, which was great. But that's long gone now.
Look on negri for the T-Mobile variant. I think its M919. I'm not sure. T-Mobile developers have been able to make great roms for the device, instead of wasting so much time to find a workaround. Maybe even try T-Mobile out and see if they've improved in your area. They got a lot better in my area, but still a lot of EDGE.
If I were you, I'd go for the Nexus 5.

Heres my suggestion, if you want the s4, get it from best buy than sell it unopened for as much as you can and than with the money you get buy a tmobile or i9505 international variant...(not i9500 or the verizon or sprint one)
The tmobile variant is probably your best bet, the tmobile variant supports all of ATT service bands so youll have no issues with reception or internet. The tmobile variant can flash roms from any of the other s4 variants (verizon sprint att i9505...just not any roms from the i9500)
So in other words if you get the tmobile variant you dont have to worry about a dead dev scene as you can always flash roms from a differnt carrier...only thing is you will probably have to set up your apns for att rom flashes
Hope that helps you
And on another note if you decide to stick with the ATT s4, every firmware can be rooted
Mdb has real recoveries, so you can flash anything as long as you "loki" the kernel - Unfortunately I do not think there are any stores that are selling phones with this firmware
Mdl has real recoveries, so you can flash anything as long as you "loki" the kernel...Unfortunately it is pretty much impossible to find a phone with this firmware in any store now
Mf3 has safestrap which is kinda like a recovery, with it you can flash any touchwiz based 4.2.2 rom (stock roms) or any 4.2.2 Google Phone Edition (aka GPE, which is an aosp experience S4, no bloatware no samsung features, its like having a nexus in the body of an s4) rom...NO CUSTOM KERNELS, NO AOSP ROMS (no cyanogenmod) - this is the firmware most phones come with
Mk2 (latest firmware) recently got a beta safestrap...as of now you can flash some 4.3 touchwiz stock based roms, alot dont boot yet, and the GPE 4.3 rom doesn't boot with it either. As it becomes stable it should work identical to the one for mf3 - phones will probably start coming with this one soon
In other words, safestrap allows you to run roms that are built off the same firmware version as your stock rom, safestrap flashes no kernel, so whatever rom you flash has to be compatible with the stock kernel of your current firmware

They actually seem to be getting close to another work around which will allow you to flash any rom or kernel using safestrap...turns out theres a feature in the 4.3 mk2 kernel which allows unsigned drivers to run, in theory they can compile a kexec driver for the kernel which would allow you to use any kernel thus allowing the flash of any rom...theres a how-to thread in the original development section with more info, however...its not a guarentee we will see this anytime soon, as you never know what issues they may run into...but something to look into if your interested
EDIT: actually heres a post from the thread i mentioned which pretty much sums up how we hope this "exploit" will work as far as kernel flashing goes http://forum.xda-developers.com/showpost.php?p=48703510&postcount=10

With all that said; how come I have the MF3 baseband my s4 (jflteatt), and I still have a custom recovery with the ability to flash different roms and kernels? Is it because I installed the custom recovery on an earlier baseband and then it got updated to a newer baseband but still kept recovery?
I only found out I had MF3 on my phone now because I couldn't flash a different recovery anymore.

It is literally impossible to have officially updated through OTA while on a custom Recovery. What I suspect has been done is the same as my phone. I got an MDL device and quickly installed TWRP and a custom ROM. As new updates came out, I flashed just the baseband. So now, I have a 4.4 ROM with the MK2 baseband and am able to install anything I like.
If I were to have ever done an OTA, I would no longer be able to have a custom recovery because of a blown Qfuse.
Please don't try to say that what you have is the only phone with OTA MF3 and custom recovery.
The only way to have anything like that is through SS and that is not a true recovery. If you do have that, you can only install certain ROMs not including AOSP, AOKP, MIUI, or CM.

When did I ever say I was the only one? I asked a simple question that I mostly had the answer to already; which in turn was answered by a simple "Yes" from HiTideBlastoise.
And I never said anything about OTA either. I said I had installed custom recovery on an earlier baseband and then my baseband was updated but recovery was still intact.
I never said you did say that. It was preemptive. Secondly, you make it out to seem like you did nothing to update your baseband. You are making it seem like it just happened. Well, that can't happen without either updating the entire phone or flashing it yourself. The funny thing is the baseband means nothing when it comes to recoveries and flashing ROMs. It can only be used as a possible sign on a stock device as to what version one is running. On a modified device, like yours, it is worthless information on the version of Android. Like I said before, I have 4.4 with MK2 as my baseband. How can I install ROMs. Not because it updated my baseband after I already have a custom recovery... But because I never took an OTA and made it do the stuff I wanted.
Basically what I am saying is that you need to be clear with what you say. Everything you said makes it sound like your phone did it all by itself without you or someone else making it the way it is. There is no other option. You have to have done something to have a custom recovery and an MF3 baseband with pre MF3 bootloaders.
Sent from my SAMSUNG-SGH-I337 using XDA Premium 4 mobile app
I agree with graydiggy that the only way to still have a custom recovery and mf3 baseband is that you either flashed an mf3 tw rom with a modem or a a standalone modem to your mdl software. If you took the "OTA" successfully, you will definitely have a locked down bootloader now.

[Q] KIT KAT on contracted Samsung S4 AT&T i337?

I have had my S4 since switching to ATT in late November and have been following the XDA forums very closely since then. It was thanks to the XDA forums that I was able to root my S4.
However, no matter how far, wide, and meticulously I look on the site, there is no mention of the existence of running KIT-KAT on the i337 S4 for AT&T, save for the Google Play Edition and the version with the octacore etc.
I know these forums are strict (and should be) about questions being asked more than once, but I am not asking when KITKAT will be released through AT&T or even Samsung because I honestly don't care. I simply want to get KitKat on my device running with relative stability. I know there are custom roms out there, but most of them were released...a month ago or so? MAYBE I'm missing something, but if anyone here is in similar shoes, I would appreciate it if you'd echo my sentiments/request to find out if it can be done and how.
Anyone who knows how I can learn more about loading ASOP onto my i337 S4, I would greatly appreciate it. If the limitation is a locked boot loader that you CANNOT get around (excluding safestrap), do let me know! I'm sure a lot of people would benefit from the answer to this question.
Otherwise I'm going to go buy the Google Play Edition of one of the Android devices that has an unlocked boot loader.
Cheers,
Justin

What version are you currently running. Go to about phone and post your baseband version. If the 2nd to last digit is f or higher you can't get kit kat yet. If it is before f then you are free to do whatever you want., If you are rooted you can just download rom manager from the play store and flash a recovery the easy way. Then get cyanogenmod or something for your device.

Thank you for your reply!!!
That is most unfortunate, since it is i337UCUEMK2 - even if I did some crazy stuff to go back to MF3, I'd be right at f anyway. ROM Manager and flashing a recovery the easy way seemed simple enough and I was going to do that but it ended up not working, then I tried using Goo Manager and that soft-bricked my phone and I spent hours getting it back to MK2 again. It's back to the way it was, but I still want to update to Kit-Kat.
Btw, could you tell me why it isn't possible because of my baseband? Thanks failedjedi, and anyone else that can offer useful information.

With mf3 they locked down the bootloader. So before mf3 you were able to put a custom recovery and custom roms. Since MF3 no one has figured out how to bypass it yet. With mf3 you can use safestrap to sort of get some custom roms, but it still needs to boot the stock kernel as you can't yet use a custom kernel. As a result you are limited to only 4.2.2 Touchwiz based roms working. Now safestrap has a beta for newer versions, not 100% sure what it does and does not support yet as I'm sticking with my mf3 and a 4.2.2 jellybean rom. But the beta is new and probably still buggy.
But basically since you need the stock kernel, you are limited to only the android version your current stock version is.
Yeah as an android developer, I accept that, but am not going to permit it to remain true. This might take awhile...

If you are a developer there are bounties out for someone to get this working on mf3>
I don't have that issue but good luck if you try--:good:
Thanks! Didn't really know there were bounties for that - worthwhile ones anyway given that im dev apps and messing with AOSP and mainly my att s4 every chance I get.
Actually id be doing it for mk2, and if it becomes apparent that mf3 is easier to do it with ill do with that since I'd just DANGEROUSLY use Odin to go back, root, sideload titpro and block the sht out of the autoupdate. From what ive seen, the intermediary version between mf3 and mk2 might be most likely. This is all conjecture anyway. Sooner or later I will allow people to be free even with contracted or used phones.

[Q] noob seeking advice

i have been thinking about rooting my gs4 for a while now. i think i have finally decided to pull the trigger. i jail broke my iphone4s when i made the mistake of purchasing it. i dont know how much that experience will help. anyways, i came across this thread http://forum.xda-developers.com/showthread.php?t=2567353. what i would like to know is if this is something that is feasable for me to pull off. is it more for somebody that has more knowledge in the area than me? one thing i noticed is that the screen shots posted in the other thread have a different kernel, will my phone be loaded with that kernel when i load the rom? my phone is a gs4 sph-l720, currently running 4.3, build number jss15j.l720vpuemk2. any info and advice will be greatly appreciated.
Yes, you will have ktoonsez kernel on your phone if you flash that rom.
It is very feasible and actually quite simple to root your phone. Find Cf autoroot and philz touch recovery in the original development section and just Odin them in.
Just be aware that you will trip the Knox counter on your phone and will void your Samsung warranty.

thanks for the info. i only have a couple of months left on my warranty anyways. i have had this phone since may of last year. i plan on following the instructions in the post. hopefully i get it all done right.

[INDEX][Everything you need to know][All In One Guide]

Welcome to the note 3 forums. We welcome you as long as you do your job and search before making 1,000,000 new threads.
So,You just got your shiny new note 3 and dont know where to begin?
Well that's ok because, this is the all in one thread.
Lets begin​
How do I Root?
That is the common question around here. Im going to simplify this.. Here you go
For 4.3
1.The best and safest way is this method by @evilpotatoman. It does require a little work but in return you do get root Here is the link for That,
2.Another method that is faster, but does not offer busybox with install, nor did it originate from XDA-forums is Here,
For 4.4 Or KitKat
You have to Go to My thread located
Here,
This does root KitKat and provides a custom ROM.
How Do I Install Custom Rom's
First What you should know is that our phone has a locked bootloader. This means that we can not boot kernels. But we still can flash custom rom's Thanks to @Hashcode
To install custom rom's on 4.3, Head over Here,
Another method That i originally created, but does not work as good as safestrap, could be found Here
If you are on KitKat, Then you could either install my KitKat rom or wait for safestrap to be updated.
What Do I Do If I Bricked My Phone? Or if it wont boot?
Well There are 2 methods to get you back to stock and running again.
To Restore back to Jellybean (4.3) Follow this Thread Here
To Restore back to KitKat (4.4.2) Follow this Thread Here
Why are Rom's Based off different Bases & Whats the difference?
A little basic intro
MJ5,MI9 & MI1 Are all 4.3 AT&T Bases
Ml2 Is an international 4.3 Base
MlG is a leaked AT&T 4.4.2 Base
Mj5 Is the latest 4.3 AT&T Base
Ml2 Is the latest international Base
The difference depends on what you need. Right now There are pro's and con's to all bases
Mj5
-Fast Data speeds
-Better indoor Signal
-No Bluetooth internet tethering
Ml2
-NO group messaging
-lower signal in areas
-slower data
-Does have Bluetooth internet tethering
Leaked Kitkat base (MIG)
-Extremely fast
-Newer modem with better signal & speeds
-Safestrap is not yet updated to work with kitkat (But you could still install my 4.4 ROM)
Why is my GPS Crappy and How do i fix it?
This issue is well known with our phone. The main reason is bad software coding.
To fix this issue Flash this fix made by me, in safestrap or manually push the files using root explorer.
4.3-Click Here
4.4-(Coming Soon)
What is "SafeStrap & Why do i have to use it?
Safestrap is our main method of flashing Rom's and could be found Here,
Always WIPE before flashing a new ROM or expect to receive errors. DON'T BE LAZY
Issues with safestrap
-Sometimes the storage is messed up and shows that you are using all your memory, when you really are not.If you use a different app to check, then you should see your real memory usage.
Where are all the kernels located?
Like i stated earlier, We don't have kernels yet, because of our locked bootloader
Where are all the Roms compatible with my phone?
All compatible and ready to install rom's could be found Here
There is currently NO AOSP,CM Based Rom's, So don't ask
What is KNOX and how does it effect me?
KNOX is basically made to **** us. But Samsung calls it security.
KNOX is removed from most custom Rom's. Knox does prevent root apps from working properly and should be removed asap.
How do I transfer My bookmarks from ROM to ROM?
Follow the guide i created Here
Im still working on a list of roms,and cool mods that are compatible with our phone. they will be located in the second post.Mods please sticky this thread​
For me, to post mods and roms compatible with our phone
one more
Great information.
Thank you very much.
I have tried your KitKat 4.4.2. Glad to see it is rooted!
Now, it is easy to switch between MJ5 4.3 and MLG 4.4.2 through SafeStrap and Odin.
Wow very nice! Hopefully this will prove helpful.

Awesome work. Me personally Im waiting for SS to be updated but definitely keeping an eye out.
Im curious on one thing. When you discuss Knox and to 'remove it', would freezing this via TB server the same purpose? Also since youve had a go with 4.4, does Samsungs iteration of 4.4 still have the GPS issues or did they fix it? Just curious
Thanks!

Wanting to down grade back to JB rom from KITKAT v2
I Used to be on JB rom 4.3 And I really liked it. But I wanted to upgrade to to KitKat v2 because alot of people said they liked it. After I upgraded to KITKAT 4.4.2 I really did not enjoy it as much JB 2.6. I used to get 35000 score from Antutu Benchmark but now on V2 I get about 30000 score. And I thought the JB 2.6 was setup nicer. I dunno, but what I do know is that I would like to go back to JB 2.6 because I think it was a nicer piece of work.

Negative. Only touchwiz based roms will work with 4.3 MK2.
Your best bet is using an AOSP themed ROM such as blackbox or purified. You can find some more info here... http://forum.xda-developers.com/showthread.php?t=2616221
Or, more simply, install a new launcher such as apex or nova and then you won't have to worry about touchwiz
That's extremely disappointing. I'm really starting to hate this phone and I think I'm going to call att tomorrow and see if I can get something else. Perhaps an htc one or lg g2. But this isn't going to work out. This is not the level of customization I want. Touch wiz goes deeper than just the launcher, and what happens in another year or two when att stops providing updates? No, I'm done and I don't want this thing anymore. Bad ATT and bad Samsung.

I'm no expert, but anything other than MDB and MDL means a locked bootloader. AFAIK that means, all safestrap does is let you load a different rom, but that rom has to be based on the touchwiz kernel. That means no AOSP and that means no CM11. I'm in the same boat.
Hello,
Sorry to revive this after several months of inactivity, but I have exactly the same problem and am confused by the information I have found on XDA, possibly a fault of my own. I have a Galaxy S4 AT&T i337 with MK2 4.3, and I want to run CM11.
A much much more tech savvy friend of mine setup my phone in January 2013 with CM11 using the TWRP recovery. It originally was just the AT&T stock everything. Unfortunately, I no longer have contact with him, and I have no idea how he did any of this . I was specifically running the build from here: http://forum.xda-developers.com/showthread.php?t=2383143, which is now here: http://www.handy-faq.de/forum/galax...h_app2sd_glove_mode_dual_boot_for_all_s4.html
Since then it updated automatically to the last nightlies without any issues. Two days ago, however, I updated, and my phone went into a boot loop. I booted into recovery and tried to flash the last version that worked, but that resulted in my phone staying in a boot loop without being able to boot into recovery. I then used Odin to flash the original firmware and stock ROM, and now it works fine, but I miss CM11 very badly (or more accurately I find the stock ROM annoying in comparison).
The previous posts here indicate that CM11 cannot be installed on the i337 MK2. Also, this thread http://forum.xda-developers.com/showpost.php?p=42320414&postcount=2 lead me to this thread http://forum.xda-developers.com/showthread.php?t=2428254 which says "Also, at this time, only TW based ROMs will work with SS. CM, AOSP, AOKP, MIUI, etc will not work." But I do not actually understand the difference between Safestrap and TWRP enough to know whether or not Safestrap not allowing CM11 means this model won't allow CM11 at all.
I would like to understand why there is indication that CM11 cannot be put on the i337 MK2 when my friend somehow succeeded. Then perhaps we can succeed in devising a method to install CM11 on this model. I apologize for not having any proof that it worked, but I swear I ran CM11 on this exact model and firmware build for many months very happily.
Does anyone have any thoughts on this discrepancy? Sorry if this is a naive/stupid post. Thanks in advance to anyone who chimes in.
