I have a AT&T Galaxy S4 SGH-i337 on MF3 and Region Lock Away unlocked the Region & SIM. I tested it with a T-Mobile SIM. The OP of the "Region Lock Away DOES NOT CLAIM it will work with the SGH-i337 but I have unlocked a S3(SGH-i747) a S4(SGH-i337) and a Galaxy TAB 2 (SGH-i497) it was worth the few bucks.

Just curious... is this what you mean when you re-flashed MF3? Did you look below on that same page and followed the ODIN outline as to how to flash?

MF3 to google edition

I am on the MF3 rom, and I am currently doing the OTA update. I noticed there has been some breakthroughs recently with stock firmware's being available. mainly the original shipping one. so here is my question.

Can I odin flash a stock firmware (MDL) as long as it has MDL bootloaders? will that overwrite my phones MF# bootloaders and allow me to flash google edition roms to my phone?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] IceTwig:
Basically with that OTA you are doing, you are going from MF3 to MJ9. The qFuse issue will NOT allow you to downgrade.

stuck at black screen

I am trying to flash a GE rom 4.3 to my s4. When I try to boot to the rom I get stuck at a black screen.

I have an I337 with MF3 :( using safestrap 3.65

Everything flashes ok without any errors and seems like it should be working. The lcd even appears blue like when normally booting except I cant see anything.

This is the rom I am trying to use here: http://xdaforums.com/showthread.php?p=47718525#post47718525

I am flashing the rom and the build.prop files

Also I have tried with and without loki and also with and without mf3 modules with the same results.

Where am I going wrong? I thought maybe it was an issue with the firmware on my phone until I read through others with the same firmware having no problems.

Thanks in advance for any help

Capacitive button lights

I searched the thread and couldn't seem to find anything on this so sorry if this has already been asked/answered, but does anyone know where the files are located that set the brightness for the capacitive button lights? I wrote an init.d script for my old phone (LG nitro HD) that would set the brightness to 0 so the button lights would stay off but the location is not the same on my S4.

Edit: never mind, I found it! Tested on CM11 unofficial and it works (didn't realize this was an MF3 thread but I believe this will work on TW also). If you want to use it just create a new text file on your sdcard and copy and paste this in it

After saving, rename it to "99buttonbacklight" or something like that but delete the .txt extension and place it in your init.d folder and reboot.

I don't know if this thread is still being checked, but I'll post my questions anyway.

I have an AT&T Samsung Galaxy S4 (SGH-i337), with baseband = MF3 and Android version = 4.2.2

I want to flash another ROM on this device. I already now that the bootloader is locked and I'm stuck with using SafeStrap and TouchWiz-based ROMs

I've read quite a bit in the last few days, but can't seem to find the answers to some issues:

Can I flash a 4.3 or 4.4.x ROM on one of the new ROM slots that Safestrap creates on my device?, leaving my Stock ROM untouched, that is

Can I flash a 4.3 or 4.4.x ROM if I update my stock ROM to 4.3 or 4.4.x?

Does SafeStrap work on Android 4.3 and 4.4.x? I've read that the 3.7x versions of Safestrap "kind of" work but they have issues

If I keep my stock ROM at 4.2.2, should I use Safestrap 3.65 or Safestrap 3.7x?

If I update my stock ROM to Android 4.3 or 4.4.x, can I go back later to the original version (4.2.2)?

Hopefully someone can chime in and help me out.

Thanks in advance

I have a 64gb sdcard - yes the stock rom read it. I saw something about it needing to be re-formatted in FAT32 or something like that...Do you know which? It will read it and then it is usable, then disappears and remounts...does this several times. As of now, it has been mounted since last night, so maybe it was the ROM settling in...

I do have the 16 GB version. So, just to understand, When I go to settings > storage > I see Total Space: 9.72 GB. So that would be the 4 GB that Samsung has allocated and then the other is for Android OS?

Thanks again for your help, and this thread! I think if people read titles to the threads, then they wouldn't create extra clutter...I've been in lots of forums, but not this one as I just switched to Android and see the value of this thread.

With the GE Roms is it possible to have a ROM like AOKP, and have touchwiz apps as well? Basically is this the beginning of touchwiz and AOSP being married?

Thanks.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Matridom:
The google edition has touchwiz framework built in. So yes, any of the samsung apps *should* be able to be ported to the GE. In a different thread i'm keeping up to date on, they have a working version of the samsung camera app on the GE, MMS, etc.. for the more advanced features like air gestures, multi-window and such, i think it will eventually come as the developers work at it.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] AxAtAx:
You can bet they will, soon, cause the rom is basically basic at the moment, alot of features are missing.

many are for the general features of the phone. Should be soon, I agree.

[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Matridom:
It's so much easier to work from a blank slate and work up the features that you want vs trying to strip out what you don't want. Personally, I love the stock android (I've been using it for a few years already). I think the only touchwiz feature i would be interested in is the high sensitivity option for the touchscreen (so that it works through gloves), Being a Frigid Canadian, this feature might actually have some use to me - if it works properly.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] AxAtAx:

[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] scarmon25:
Unless someone wanted to compile Android from source using the kernel source code from Sammy. Even if someone wanted to do that they would most likely have to beat through some bugs. For now it is as close as we have. That and it is the one on the Google Edition of the S4 so everything works on it. If a dev wanted to compile a vanilla AOSP I would love and donate to the project. But I don't expect anyone to do it. I would if I had my laptop but unfortunate circumstances have made it go bye bye.

The modem.

So if this is a new device, that is now running its own firmware and blahblah, wouldn't that mean it has its own radio/modem thingy? I know that at least for AT&T users (like myself) there are the MDB and MDL radio/modems to flash. If this phone is meant to be a GSM unlocked Global phone and whatnot, doesn't that mean the radio/modem could be extracted and slapped in a flashable zip, and prove possibly... useful to pretty much anyone running a GSM S4?

I posted about this in the actual radio/modem list-thread, but it didn't really get a response.

Both the 4.2 GE edition and the 4.3 leak have a different modem.. It would be possible to extract and flash.. Not sure any benefit will come from it as every bodies phone and location can help play a part in performance reception wise but it definitely could be useful to have an additional modem to try.. I just flashed both 4.2 and 4.3 and I'm still on the original modem I had on aokp and tw so as is pretty standard the devs made the ROMs not to flash the modems but I'm sure it'll show up separately soon
