need some assistance with i337m and getting back to stock. - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have read a fair amount here, but I'm not getting entirely relevant info and am hoping for some help.
I THINK I have finally found the place for stock roms. sammobile.com???
Now a bit of background.
I bought this phone used a few days ago. When I had a look, it is already rooted, which I'm fine with.
It is running 4.4.2. I'd like to upgrade to 5.0.x. Gotta friend with the same model. That's what he recommends.
I can live with 4.4.2 if I have to, meaning if I can't upgrade.
Since this is new (to me) I can live with losing all user data. Only thing is my wifi password is long and random and a pain to type in, but that is about all I'll suffer.
I had removed some apps using debloater, mostly just to see, but have since restored them. Then tried to update, got the message, which essentially says "you've got a custom rom. No updates for you".
I know the phone is unlocked, but not sure if factory or by unlock code. Does it matter, and if so, how can I tell?
I know the previous owner had a fido sim, and I noticed some bell apps on here. If I've read correctly, that doesn't guarantee this was originally a bell phone. Is there any way I can tell? Right now I have no sim. I can shove in an old speakout sim that is deactivated.
So anyway

I've downloaded ODIN, but not a ROM yet, since I'm not positive who's I should use.
Also, I had gone thru the guide to enable AWS. That seems to work, as it would take the sim at the wind kiosk. I'd like to keep that, but if I have to redo it, that is fine.
I trust it is not a good idea to upgrade to a "stock" 5.0.x by just flashing roms?
Thx for any help.

ok, another question. I just registered at sammobile, but they don't seem to have roms for the S4??? Are they hidden somewhere? Where can I get stock roms, if not there? Thx
Nevermind. You have to type in the device name. It just isn't on the pulldown list.

Another question you might find stupid.
If I update to (for example) the Bell Roms, do I have to have a valid Bell sim in order to do an update?
Well maybe 2 stupid questions.
I still have to use triangle away for flashing back to 4.4.2 don't I? I read somewhere that they (meaning Samsung) expected the count to be > 0 at some point but I don't remember at what version, and I can't seem to find it again.
So what do you guys do? Flash it a couple of times to get the count right?

If the phone is sim unlocked, it should remain permanently unlocked regardless of whether you flash custom or stock ROMs.
The easiest way to get to stock LP would be to flash the stock LP rom via Odin from here: http://www.sammobile.com/firmwares/database/SGH-I337M/
Before the first boot with the LP ROM, the phon should be factoru reset via stock recovery.
Doesn't really matter whether you flash Bell, Rogers, or Telus. The hardware used by all 3 carriers is the same. The only difference would be in the apps that are installed with each stock ROM.

I think I have reflashed properly. I'm downloading the update (probably to 5.0.1??) via phone now, but I noticed after I started that I have the warning triangle. So maybe the update will not install when it is done. I'll know in a couple of hours I guess.
So I should have run triangle away BEFORE the reflash? Or are you no longer supposed to run that? Or is there some android version after which you are no longer supposed to use it?
Thx

Well, phone seems to have updated to 5.0.1, which is what I wanted. With the update, the warning triangle is gone also.
So thanks again for your help. I guess I'll be on to other things here.

[Q] Cannot update firmware via official channels despite reinstalling stock firmware

I don't know what's going on here.
I've had a rooted phone for a while, but wanted to update to 4.3 since that came out recently.
So I've reinstalled the stock firmware on my I9505 (XXUAME2, Poland), the whole big package. Installing this went without a problem, and now I'm back with a stock ROM. I did this because I wanted to go the official update path (perhaps I don't really need this, but... well, I'm a flash-addict).
However, if I try to find a new update using the "Update" button in the "About device" menu, all I get is an information that I've already got the latest software.
KIES, on the other hand, tells me that my device's current firmware version is not supported.
What's going on here?

Hi,
Did you try Triangle Away,from the market?
It will show if you triggered the flash counter.
Having said that,you still have the old ,non-knox bootloader.
You might want to just keep that and flash custom ROMS.
They have all the goodness of official ones,but you are still free of any restrictions.

I've used Triangle Away before, to reset my counter. Of course, after flashing in the official firmware the phone's no longer rooted, so Triangle Away won't work.
That said, I THINK I know why the official update procedure(s) failed - I've mixed up the firmware for my product code. Apparently when I originally rooted the device I've changed the product code to BTU and have been using that ever since without really knowing about it. But now I've installed the Polish firmware XEO, and I think this is why the update process went crazy.
With regards to custom ROMs... I've already got the phone configured the exact way I like it, and I know some custom ROMs can be... quite different. Are there any specific custom ROMs you had in mind that have all the goodies of official ROMs without the restrictions you mentioned?

Hi,
TA is used while you are still rooted to reset the counter.
Then, you install stock ROM/firmware.
Only you know how you like your phone,so only you can make that decision about the ROM you choose.
The main restrictions are that once you root the new firmware with the new knox bootloader, you will trigger the knox warranty,and you will never be able to flash an older firmware.
Not everyone is bothered by this,so, this is all a personal choice again.

Any chance there's a custom ROM created from the stock firmware but with the bootloader removed?
I've read about Knox and I'm kind of glad the firmware update failed, as I wouldn't feel comfortable with that "warranty void" flag...

[Q] Upgrade to MK6 modem?

Ok, I'll start by saying that I'm trying to update my rogers 1337m to a custom ROM based on 4.4. The phone came with 4.2.2 on it and the 1337MVLUAMDJ modem. Since having bought it, I rooted it with motochopper, kicked the samsung firmware to the curb, and installed jamal's 4.2.2 google edition rom.
Anyhoo, now I want to install jamal's 4.4 rom. I installed it, but the phone doesn't work. I can't make calls, mobile data isn't working, and I get no bars in the signal indicator. I restored my nandroid backup to 4.2.2 and all is well again - calls, mobile data, and signal reception.
Do I need to upgrade my modem firmware? I have the MDJ firmware, and I noticed that there's an MK6 firmware that seems to be newer. Jamal's rom actually comes with a modem, I9505XXUFNA1, but when I tried installing that with Odin, it said 'security check failed'. I'm guessing that I can only install Canadian modems?
What would be the pros/cons of flashing MK6? Does this unroot my phone? Does this lock my boot loader? I seem to recall that AT&T pushed out an update that locked their users' phones in some way. Is that what I would be in for?

The i337m will never have a locked bootloader. AT&T was never unlocked, we only had an exploit. Updating yours will get you Knox however, i believe. There is a thread of the modems so you can flash just the modem by itself.

I've seen knox before in my process list - when I had the samsung firmware installed, I thought knox was just an obnoxious ( obknoxious? ) policy agent for enforcing exchange rules or something. I've seen neither hide nor hair of it since I installed the google edition ROM, which of course doesn't come with knox. So you're saying the the new modem might have some knox component in it and this might cause problems?

Well if you already had a version with knox it doesn't make a difference. It's just that the newer official firmwares have the knox enabled bootloader and it adds an extra flag beyond the normal system status that would void your warranty on flashes but if you already have it then it doesn't matter. It wouldn't cause any problems, just adds that little flag and I'm not sure if recoveries are made to not trip that flag or what.

As far as I know, Knox is not part of any modem firmware. Someone please correct me if I'm wrong.

It isn't, flashing only the modem packages does not include knox. Using the full system ODIN or Heimdall files will include it if you update the bootloader.

Yes.
First, I don't think that it was strictly necessary to upgrade the modem to get 4.4 - I think it might have just been a problem with jamal's ROM and the kernel he used. Anyways, I decided that I wanted the new modem anyways because I reasoned that it would probably have bug fixes and performance and reception improvements. I was pretty sure that flashing the official 4.3 Rogers image (there is no 4.4 Rogers image) with Odin would give me the new modem. Then I could flash whatever aftermarket ROM I wanted.
Strangely, this didn't work. At least not the way using Odin is recommended. Odin has two text fields pointing to tar.md5 Roms - onw of them is marked 'phone' and the other is marked 'PDA'. As I recall, I had to point BOTH of these at the official Rogers 4.3 ROM get get both the Samsung/Rogers android along with the Qualcomm mk6 modem. I don't think I've ever found a how to where they recommend using both at the same time.
After that, I flashed a Google edition ROM and all is well. And the new modem does seem to get somewhat better reception.
So there is no way to update just the modem from a custom ROM (without wiping everything and installing a stock ROM) for Canadian S4s?

[Q] LTE Support on Rooted Note 3 Ireland

Hi all,
First of all I'm sorry if this isn't the right place for this thread, it just seems like the related threads are in this forum.
First of all I have the international unbranded version of the note three (SM-N9005), which I rooted in order to use VPN. I did this using the chainfire method which of course tripped the knox flag, I'm not griping about that because I don't really care about the warranty, just giving facts.
This then prevents the phone from checking for updates properly saying "device has been modified" or something like that.
I'm on three ireland and they very recently switched on 4g/lte network support but you need to accept an ota update to enable it. Therein lies my problem, I can't accept an ota update.
I would have no problem unrooting to accept an update, but that doesn't reset the knox flag and my phone will still show up as modified and considering the amount of effort I would have to go through to unroot just to end up on the same situation as I'm in already is not worth it.
I have tried the viaero 4g toggle app but this just gives a black screen for me. I also tried the persist.radio.lteon.xml fix but I couldn't find that file to change the setting. These solutions suggested here http://forum.xda-developers.com/showthread.php?t=2468624&page=2
So my questions:
Is there any way to flash some sort of firmware unofficially to give lte support?
If I flashed a custom rom would that give me lte support? Or do I need to flash the official 3 Ireland lte firmware first?
If that will work, can anyone recommend a rom to install?
Finally has anyone managed to get themselves out of a similar situation yet?
Hope somebody can help,
Thanks for reading
Barry

If you reflash back to complete Stock your status will show Official, also you can try a custom ROM, ALL of them are capable of getting LTE by default. I have no issues with them.

Thanks for the quick reply radicalisto, to be honest I'm ready to move away from touchwiz so a custom ROM sounds like a good solution to me. Choosing one is the conundrum. Are any of them more stable/full featured than the rest? I would appreciate any advice about a ROM to choose.
Well to be honest, custom ROMs are trial and error, but the new Kitkat ROMs are awesome, I personally tried them all and have settled on one (won't say which cause it may sway you haha) - however these are TW based ROMs.
If you are on 4.3 still and fancy CM11 -- Two ROMs you should try are temasek's CM11 + Yank555's kernel (amazing pal) - Or ProBAM with Yank555's kernel (Just as good as temasek's) both are packed with great features, awesome battery life and generally just great. However you may or may not know, CM doesn't support SPen functions, you'd have to use GMDSPen or another alternative.
EDIT: Little side note, again not sure if you are aware.. if you flash Kitkat 4.4.2 your bootloader upgrades so you cannot use CM, as it runs on 4.3's bootloader, there is no downgrade option either currently.
Not that I'm so concerned about the CM bootloader using 4.3, but would I be safe in assuming that the CM team will have to eventually switch to the 4.4 bootloader?

Well you're allowed to tell me as I was asking to be swayed...
I'm thinking I'm going to try x-note first as it seems to be the most popular and I'm guessing it's that way for a reason.

[Q] Seriously desperate...

Ready to sell this phone... tried everything I know how to try... Dev Edition Verizon S5, CAN'T UPGRADE from stock NCG. The most I can do it root... any ROM I flash is nonfunctional on Verizon's network with NO SIGNAL. Replaced SIM, flashed modems, etc etc... I think I'm just not sure how to do it with a dev edition... seriously feel like I'm missing a step. Would like to start from scratch. Does anyone have a stock image of a G900V Dev Edition I could work from, since I'm starting to think the one I've been working from is somehow the incorrect version. Thanks!

I would but I'm trying to avoid locking the bootloader, if possible. Didn't intend on having a developer device, but now that I do, I'd like to try to maintain it's use as one. Bought this phone on swappa, seller didn't give any indication that it was a developer device. Now I'm concerned he did something to it prior to selling that is causing me difficulties. I don't think I should be having these network difficulties, but there could very well be something I'm supposed to be doing with the modem that I'm just unaware of. I figure if I can get back to the way this phone was when it was new (when the original seller bought it) I'd at least have a clean slate to work with.

I don't think so, but thanks... I think that's the same device firmware that the retail version comes with, which will lock my bootloader. I've actually considered just flashing it anyway and saying the hell with an unlocked bootloader, since I didn't really intend to have one to begin with and apparently there's nothing I can do with it, anyway (none of the unified builds work on my device, anyway) but this is a last-ditch effort to preserve it if i can, and I'm hoping some dev will be willing to help me diagnose my problem.

It's not like there's a ton of development going on for Dev edition. I'm loving the retail version of the phone just rooted and running some Xposed. Like it so much, I went out and got one for the wife too and I paid full retail for both to keep my old unlimited data plan. Hers I just left out of the box stock. Will be interested to see how Lolipop looks when it drops to her phone. Sure hope we keep root with Lolipop, I use the heck out of my hotspot, to the tune of about 70gb/mo ...

I'm far from a developer, but this may help. I also bought the phone without realizing what it was I was getting into and had similar problems flashing the Optimal rom on my dev edition s5. I could flash but phone would hang on the activation screen with no signal. I eventually succeeded. As near as I can recall this is what I did:
I dirty flashed Beantown 4.4.4 rom (twrp) over my 4.4.2 stock firmware. then flashed n12 firmware (included stock kernel, and modem) from dev edition make an update .tar thread (odin) (http://forum.xda-developers.com/showpost.php?p=56604757&postcount=2). I did a factory reset after flashing. Switched to art. Flashed optimal with clean reset, but did not flash kernel. Later flashed koontsez 4.4.4 kernel. Still running Optimal
Good luck.

Had marginal success using this method... Have been able to maintain a 3G signal, but no LTE after first boot. Rather, when I first booted, I had LTE and thought I was good, but since my first reboot, I can only get 3G and nothing I do can get it back so far.

I did a factory reset after flashing. Switched to art. Flashed optimal with clean reset, but did not flash kernel. Later flashed koontsez 4.4.4 kernel. Still running Optimal
Good luck.

This happened after I flashed the update.tar (with aboot.mbn removed) and I have note gotten LTE back. Is there something I can do with my aboot.bak that I'm missing?

SGH-I337M unlocking?

Hello!
To begin I would like to apologize for my english and for creating another threat for this issue (I know there are several already existing).
My issue is the following, I got a Samsung galaxy S4 (sgh-I337M) here in my country (Colombia). I payed for it but didnt try to use it with my sim when I got it (which was really dumb). The phone is locked, it is from telcel and I have been trying to unlock it for sometimes. I have followed several procedures that I feel like im able to do, and there were some that were just too complicated for me (im tech savyy but dont have enough knowledge about cellphones).
I have tried several methods using the *#0011# and I even dare to try one that involved flashing the phone (using this rom I337MTCEFNE2) because it said it would be unlocked after it (didnt work).
I would like someone to help me with the process to unlock it (even if its with a link and some help understanding the basic concepts). Im in coombia and would like to use it here in my country.
So far i would also to know if by using a custom or official rom i would be able to unlock my phone, even if its using the rom from my country (that was not the original for the phone). Also looking at the roms available for Movistar )a carrier here in my country) I found that there are only roms for Kitkat, and I would really like to have lolipop... How does it work exactly?
Thanks to anyone who can assist me with this! And again, I apologize for creating another threath, but i already search a lot.

The rom I used to flash it is running on 4.4.2. So I dont download the 2 roms that you put in that post, but the original ones for the cellphone? I think this phone was supposed to be with telcel.
There are 3 roms for that carrier:

The modem rom is for 4.2.2, is there a way to upgrade my android version after following this procedure?
Sorry if i ask a lot, is just that im not sure about how roms does exactly work and what do they affect the phone.
Thank you very much for the help!
The phone will not work with a stock 4.4.2 rom and a 4.2.2 modem. After running the region unlock app, flash the stock 4.4.2 rom again, factory wipe, and the phone should be sim unlocked.
I would flash the ne2 rom, then root, 4.2.2 modem, run region unlock, then flash the latest 5.01 rom, factory wipe, reboot, and check the phone.
