Anything before MF3 is buggy on 4.3 ROMs on the i337. So you can use MF3, MK2, or newer. However, if you're using the AWS mod (to enable 1700 MHz for T-Mobile 4G), you need to use MF3 and then redo the mod because it won't work on MK2.

Help

Hey Guys,

Please help me out. I have a I337M Telus device.

I flashed several 4.4.2 roms and I keep getting my mobile connection dropped after I place a call. The call goes through, but the next one doesn't find a mobile network. The network connection comes back after a minute or so.

I tried flashing MK6 with Odin and Mobile Odin Pro but the Baseband version still shows I337MVLUAMDJ

I'm baffled as to what to do.

Appreciate any help.

Thanks

Flashed it twice (again) and it worked!

My apologizes if this has already been asked but this does unlock the US veriant of Ver I545 correct? and if so im not sure which one i will need to download. my current baseband is the MDK. Im running Hyperdrive rom build MJ7. can i perform this unlock straight from this rom or must i return to stock rooted MDK. Also its been awhile since i needed Mobil Odin, Im assuming it has been updated for the s4 4.2.2 and 4.3?

Thanks for the help and once again I apologize if these are repeat, just really want to get this unlocked and I also have a US Ver S3 I535 i need done too if there is a way and someone can point me in the direction for that.

Well I know that they are Global unlocked do to the fact you can set it to global mode and use anothermake calls and text. However data will only be 2g unless you sign up w their International service, but even then I don't think you'll receive 3g or higher data. So I need to have these unlocked to where I can switch to any carrier in the US and it will get the higher data
[AT&T Samsung Galaxy S 4 Android Development] Product F(RED):
On the Galaxy S3, you can't use it past EDGE (2G) in the US. It's simply not compatible with any US frequencies past that. There is no magical hack that can fix that.

For the Galaxy S4, you will get up to 3G ("4G") on AT&T, but no LTE. You will get up to LTE on T-Mobile though.
[AT&T Samsung Galaxy S 4 Android Development] StifflerServices:
OK and is that possible following the steps in the OP? I tried taking my Verizon s4 to Att and they couldn't get any data higher than Edge w one of their active sim cards, but said if it was unlocked it would be able to
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
It's hard to say, never had the opportunity to switch carriers using the s4 and actually seeing if that method would work.. whether the phone is unlocked or not , it's not an international phone so you're Verizon phone would already be set to the right frequencies.

[AT&T Samsung Galaxy S 4 Android Development] Product F(RED):
The partitions across models are different. You can't cross-flash modems unfortunately. I would love to be able to actually flash a T-Mobile modem onto my AT&T S4 i337 so I don't have to rely on the AWS mod to enable 1700 MHz (I use T-Mobile).
[AT&T Samsung Galaxy S 4 Android Development] joshw0000:
Thanks bro. I thought I read somewhere that you could on unlocked phones.
[AT&T Samsung Galaxy S 4 Android Development] Product F(RED):
Since the S3/Note 2, you can't. Before that, you could flash a T-Mobile S2 modem onto a Skyrocket, for example, and enable T-Mobile frequencies. But now it results in no signal, bootlooping, and IMEI loss until you flash back your own model's modem (believe me, I've tried).
[AT&T Samsung Galaxy S 4 Android Development] joshw0000:
Damn, I worked hard to get to this point. I want this phone unlocked, lol.
[AT&T Samsung Galaxy S 4 Android Development] Product F(RED):
Flashing another phone's modem won't unlock your phone. Do you know if it's similar to the i337 (AT&T model) vs the M919 (T-Mobile model)? If you know which one it is (I'm 99% sure it's just a rebadged i337), you can go on eBay and pay a few bucks for an unlock code for the AT&T model, and it might work.
[AT&T Samsung Galaxy S 4 Android Development] joshw0000:
I think it's a rebadged M919. That's what recovery I've flashed to it and I've flashed a TMo rom (not that it matters) as well.
[AT&T Samsung Galaxy S 4 Android Development] joshw0000:
So, the fact that it's really just a T-mobile (or maybe AT&T), rebadged phone, wouldn't that allow me to flash the original radio to it?

I guess my thought process is, what can I change in the phone other than the rom so that the phone will believe it's a M919 so that it will accept a M919 radio? I've debated doing a full M919 odin. I know it would fail but perhaps something would stick before it fails.

I can't be the first person to think of this. There's got to be a logical reason why I can't do this.
[AT&T Samsung Galaxy S 4 Android Development] Product F(RED):
I have an i337 and I have a T-Mobile recovery and ROM (Wicked v10) running on it. But I still use an AT&T modem with AWS mod applied separately. If you're 100% sure it's a rebadged M919, then there may be hope. People with the MetroPCS Galaxy S4 (M919N, it's literally an M919 with no T-Mobile logo on the battery cover, and only comes in white) have used ODIN to completely convert their phones to an M919. I don't know if I can find it, but I'll try. I know it exists.
[AT&T Samsung Galaxy S 4 Android Development] joshw0000:
Hmmm....I'm debating trying it. Does the I337 have an unlocked bootloader? I know Verizon lovked theirs down and I thought AT&T followed suit. This one does have an unlocked bootloader which is why I assumed it's a rebadged M919.

I can't use it for anything now so I may just bite the bullet and try. I can't find any Odin's for this phone so I believe I'm SOL if the Odin partially flashes and fails.

Someone suggested trying to flash via Odin. Seems like there are a few methods, wondering if anyone has any advice on which way to go to shake this issue. Here's more info from my previous post:

"I have an ATT S4, on MDL bootloader, rooted and running Danvdh-GE-4.4.4-06272014 version ROM.

I have been sporadically experiencing full signal loss, for a long while now, and have flashed every radio I could find, so I am hesitant to believe it is just that I need to flash a new radio as others have said.

I also have recently swapped out my Sim for a new one, just to rule that out.

I also notice my "preferred network type" in mobile network setting changes from time to time, even when I set it to GSM/WCDMA auto. Not sure this has anything to do with my problem or that's normal but really want to resolve this, so whatever it takes to fix this please any advice appreciated. Thank you!

[AT&T Samsung Galaxy S 4 Android Development] Dillsnik:
i think I need to try this. Any suggestions on a good stockish TW rom? the problem actually started when i flashed an earlier version of this same ROM and i have just been suffering with the issue for months now. Trying another ROM makes a lot of sense, and while flashing back to ODIN sucks, I'm sure if that's what fixes it I will be a lot happier in the long run

also, what does reformatting internal mean to do?
[AT&T Samsung Galaxy S 4 Android Development] :
I would try iB's Golden Eye rom and flash the full version. It is selectable thru his Aroma installer. Just wipe System/Data/Both Caches 3x thru recovery.

http://xdaforums.com/showthread.php?t=2313469

Formatting may not be correct word on the s4, at least with TWRP. CWM may still have that option and not sure if it actually reformatted. If I remember correctly it erases and rewrites the file system leaving no data bits at all. Not sure if we can do that except maybe thru terminal but forget command line. Haven't been involved with that for a long time and not quite sure if my explanation is correct.

Most just do a factory reset thru Settings/Back Up and Restore. It wipes internal but think it may leave media. I would pull external when doing those things just to be sure ext card is not accidentally wiped.

Some do it all the time others as a last resort, as the card can get too full after awhile with too many directories.
[AT&T Samsung Galaxy S 4 Android Development] Dillsnik:
Thanks so much for all the helpful hints. I did flash his rom and I really like it! But I am still having connection issues, and I am also having storage issues. In that it is telling me I am low on internal storage but really I should not at all be. Something to do with cached files that aren't deleted I think. I assume your tip of wiping internal might work at least for that, although on the DL notes for the rom he actually says not to do the full data wipe on TWRP, not sure why..

But both these issues combined I feel like it just makes sense to start clean with ODIN and then flash golden eye from there.

Since I am on MDL bootloader someone else suggested I should flash stock MDL. Going to try find that, want to make sure I flash the right one...I'm not as technically inclined as many on here.

Thanks again for all the help
[AT&T Samsung Galaxy S 4 Android Development] :
Odin may be you best bet at this point.

Not wiping data in TWRP is for version 2.5.0.2, I believe. It wipes internal?

Also worth noting, I've had this modem hang issue on every modem available for the i337 since upgrading to 4.4 ROMS. For this "test" I jumped straight back to an NC1 ROM and modem, but if the NC1 modem is really the issue, I can repeat the wipe+Odin to MDB process and install a Vision-X NF1 ROM and the NB1 modem.
