[Q] Convert I337M to real google edition

Is there a way to convert a Galaxy S4 I337M to a real google edition? I don't mean flahsing a ROM, etc....I mean, really converting it....to recieve OTAs, etc.

To my knowledge the answer to your question is no...
The GPE of the S4 is a separate device running a separate bootloader. Flashing a GPE Rom is the only way to get the experience of it on the I337M.

interesting question....i have seen posts about turning the i9505 variant but nothing for i337M
wonder if the the process applied to i9505 will work for i337M

Short answer no. At least not "pure" GPE.
Rom would be the way to go. I have Kangabean Google Edition rom which works great.

I agree with swagmiester, I've ran kangabean for a while as my daily driver and it seems to be the smoothest most stable version of 4.3 GE Roms. To me it was smoother than any ROM I've tried yet except for Graviton. But Graviton is a 4.2.2 Rom. But I don't know if you could convert to get OTA's if you would want to. OTA may make you loose root with no new root method, or lock boot loader (if that's possible. Don't really know much about the true GE S4). And may not get proper radios/modems for your carrier. To my understanding OTA's are carrier specific for that reason as well as all their other BS they want to flood your device with.

[Q] No Singal on Danvdh's Stock Google 4.4.4 Rom

I would ask this question there but I have fewer then 10 posts, I have a JFLTECAN Samsung Galaxy S4 on Bell, and I installed Danvdh's rom using the latest TWRP recovery, after the rom is installed I have no signal, this problem I only seem to run in when installing this rom, any idea's on how to fix this?

Are you able to search network on your phone? I think you may have to set up APN manually.
I am using the same ROM on my Fido S4 with Wind. No issues so far.

But my baseband and bootloader version are i337 anf rest of all are i9505xxugne8 :/ and on back side of phone its i9505 printed

It's a Frankenstein. An AT&T I337 with the IMEI of an I9505. Someone changed the IMEI before selling it, likely because the original IMEI was blacklisted.

its basically a korean convert your phone might be i337 but the best way is to go to download mode and check it there. model number on download mode is always real.

I checked in dwld mode its sgh i337....can I install back stock firmware ...see this sitehttp://www.att.com/esupport/softwareUpdateArticle.jsp?sid=KB419415&cv=820

If it's an AT&T device then you can install an AT&T ROM on it. However, doing so nets you a locked bootloader for your trouble. Install a custom ROM if you can, and don't look back.

of course you can install official sgh i337 firmware. just find official firmware from sam mobile or samsung updates and download them to your phone via odin. it will fresh start your phone on atnt official firmware but i suggest you to do some research over it before attempting any thing. in your case i see that your phone came with pre rooted firmware to change build.prop to make it look like 9505. i am in pakistan and this is very common here i was fooled for 9500 but it was sph l720 sprint model. best of luck with your update

Finally I got it....its i337...I checked imei on imei.info it says it is i337 and also checked for blacklist its all clean....and I opened back cover and see it and its written "MADE BY SAMAUNG" ...spelling of samsung is wrong ...it means sticker and software are of 9505 and hardware are i337 at & t usa carrier....I think its changed in korea...phone is converted....now planning to download stock firmware of i337 lollipop and install through odin....
if anyone have link to i337 lolipop plz share

If you install a stock ROM via Odin, the bootloader will be changed, but as long as it's not an AT&T or Verizon ROM you won't suffer any ill effects. If you install an AT&T ROM there's no going back. Unlike every other country on the planet, here in the US AT&T and Verizon encrypt the device's bootloader, because they don't want you rooting the device and bypassing their bloatware and their restrictions. So, since you happen to be in a position where you have an AT&T S4 that doesn't have a locked bootloader, you want to install a custom ROM.
If you have ignored my advice and installed a stock AT&T ROM, you'll need to head over to http://forum.xda-developers.com/galaxy-s4-att and use the information there to root. Honestly, now that you know your S4 is an AT&T model, you should head over there anyway.

..i installed stock 4.4.4 ATT software but i want to install back i9505 software becoz att is not running well in my country...it lags in sending msgs and making calls and also hotspot nd other probs....can u guide me to get back 9505 software

I tried warning you but you plowed ahead anyway. The stock ROM you put on the phone is basically untouchable, because of the locked bootloader, so you now have two options: use the phone as is, or use the information in the AT&T S4 forums to install SafeStrap recovery and from there flash a custom ROM.

Hmm yeah but i think it will work fine ...only problem is of signal network....can you guide me how to flash 9505 modem on i337 ?

No, because it won't work. I tried flashing an AT&T modem to my I9505 when trying to add LTE frequencies to my device. The phone rejected the modem, but it didn't harm my I9505 either.

But previously i am running baseband of 9505 on i337

It could be because I didn't use Odin when trying to flash in that instance. Under ordinary circumstances you shouldn't be able to flash I9505 firmware on an I337. Regardless, you can try to flash the I9505 modem using Odin, but the results at best will be unpredictable. It certainly won't change the LTE bands on the phone as those can apparently only be changed with tools we don't have.

Need Help - Unlock SIM for domestic use SPH-720T

Hey everyone, I searched and searched, I've been trying to fix this phone for the past week.
I have a galaxy S4 sph-720T from sprint
I am running on the OS slimkat 4.4.4 with modem mk5.
The only fix I can find is using the SSU.apk and running the app.
the app only works with modems under 4.4.2 - so I flashed modem 4.3 (mk5)
I run the App and it says "simlock status: checking...." and it never stops checking!
I try to hit unlock and it says it unlocked it, but nothing really happens and I cant use my SIM card.
Anyone know of any methods that actually work for them? which modems and firmwares do I need? thanks

Help PLEASE!

Hello,
I bought a Samsung Galaxy S4 with 4G (used) and was everything working perfectly. However, to be used, restored factory settings to start used the S4. With that, my SIM card (however recognize other carriers) and did not recognize it, I tried to make the unlock / change firmware / ...
When trying to install a ROM of Brazil, Odin error, coincidentally checked on the mobile screen that had written SGH-I337, logo is a US S4, with I9500XXUGNG3 firmware (4.4.2 Russian). With that, I thought the ROM was blocking my SIN, it tried to install an original ROM that SGH-I337 model and upgrading to Android 5.0.1 Lollipop ... ROM came full of AT & T apps, and left me quite disappointed.
In short, I am with a horrible ROM and without using my SIM card (I'm thinking it's physical problem).
Can anyone help me restore / install a factory ROM, if possible, Lollipop? I'm trying to do one week and could not.
Already, thanks!
Sorry for the English, I'm using a translator.

I had already reported it, but has to take this question .
It is a SGH- I337 . So I can only install roms the i337 AT & T ? Is there any clean rom ?
I already concludes the problem of my SIN card, is that the device 4g band is different from 4g Brazil , therefore, it does not recognize . But he recognizes the other SIN Card 3g Brazil . Will I have to buy a SIN Card 3g or if there is a possibility to change the band that s4 find my SIN card would be even better.
Remembering my S4 had a rom i9500

Before flashing anything else, install the Samsung phone info app to confirm the bootloader version in the phone.
If the bootloader is 4.3 or newer, the bootloader is locked and you cannot install twrp or cwm. You can install safestrap and flash custom Roms based on stock Samsung Roms.

a question, i337 = i9505 ?

Nope, i337 and 9505 are slightly different as they support different frequencies and the bootloader on the 337 is locked.

The cool thing is that the i337 was this I9500XXUGNG3 firmware that had the ability to use Portuguese Brazil , I would like to return to this firmware. How I do? I tried by Odin but always of it :
<ID : 0/011 > sboot.bin
<ID : 0/011 > NAND Write Start!
<ID : 0/011 > FAIL !
do you have any idea?

The bootloader is locked so you can't install 9505 firmware on the i337.

which leaves me with great doubt is that it was with this I9500XXUGNG3 firmware stating it was a i9500 .
with this I tried to install android 5.0 thinking that manages to come unlock my SIM CARD and still not resolved . I think a matter of size or shape of the SIM card , seila . I have a lot of headache to solve this.

Do you flashed back to stock i337 firmware and it won't accept your SIM card unless you enter a network unlock code?

I am currently using with another SIM CARD and runs regular without typing unlock code and whatever be 4.4.x as 5.0.
However the rom one that I managed to install this was " http://forum.xda-developers.com/showthread.php?t=2674223 " with root.
So I would like to set up a Stock ROM that was clean , without anything of AT & T , which before I had with I9500XXUGNG3 firmware (including Portuguese Brazil )

Did you put a pin on your sim? Did you enter the sim code too many times and the phone locked the sim?

Forget History sim card hahaha xD
Can you help me one installing a rom for this i337 without the AT & T ? Preferably a clean like that had previously , as i9500 .

The bootloader is locked on the i337 so you only flash ROMs using safestrap.
If you want to remove ATT apps, you'll have to root and use root explorer to delete them. You could also try Titanium Backup to remove apps.
