because I had the same failure installing. Good md5 and opened fine, just no install. He said he would be looking at it. Im sure he will have it fixed in no time. Great dev.

If you are on MF3 base, then you will need to upgrade your bootloader and kernel first. A kitkat ROM won't flash on a 4.2.2 base.

Best way is to backup what you want and start fresh. This guide may help...

http://xdaforums.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642

If you are going to run a 4.4.2 ROM. probably best to not upgrade to the latest 4.4.4 NJ4. I'd recommend NC1. It's the easiest to get rooted and safestrap installed.
[AT&T Samsung Galaxy S 4 General] guut13:
Thank you for testing. I've added it to the list. I see there is a small 3.01 update that you can flash after installing v3.0.

If anyone has tried it and confirmed, I'll update again. Hate to ask someone else to test, but I'm on a m919 S4, so my testing won't do any good :(

dialer codes

just flashed my first custom rom The Sickness Edition v3 -- UVUFNH7 -- TMOBILE -- 11.19.14 and it worked great on my at&t sgh-i337. i like the rom. noticed that the dialer codes i had been using like #*2263# and #*0808# no longer work. Is this how it is supposed to be? If I want to use those codes do I need to flash a stock rom? Or are there different dialer codes for custom roms?

Does anyone know of a mod that unlocks the service menu? Still trying to fix my IMEI :b
[AT&T Samsung Galaxy S 4 General] NighthawkXL:
Your dialer codes changed likely due the fact that the ROM you are using flashed a T-Mobile modem. Go into Safestrap and flash the stock modem for whatever firmware you are on. Be aware though, it may or may not break stuff in the ROM depending on how it's setup.

thanks for the answer was just curious. just for fun i have tried loaded some other custom roms and find the codes work on them.

[AT&T Samsung Galaxy S 4 General] jt1998:
Did you flash the appropriate kernel module during ROM installation? Use ATT_NB1 in post 2 in safestrap recovery. Then check your wifi. If that doesn't work try the NC1 choice then check again.

Currently, are you able to toggle your wifi option and you're just not getting wifi OR is the option of toggling grayed out and you can't do that?

[MENTION=2982241]guut13[/MENTION] sorry to use your thread for this, but I can't get a response on the rom-specific threads...

When you tested the MD rom, did you happen to test GPS?

The reason I ask is because I can't get a fix on my location... it will briefly lock on to a location about 1/4-1/2 mile from my location, then jump to somewhere else about the same distance away... repeatedly.

I'm not sure if this is a rom-specific problem, or maybe I just screwed something up...

Any suggestions?

Edit: I already tried recalibration with GPS Status & Toolbox (Pro), to no avail...

[AT&T Samsung Galaxy S 4 General] mohoXrevolution:
please guide me!

i hope you can help me guys

I was using SafeStrap w/ NC1 galaxy s4 for months now, using the GoldenFinger ROM and decided I wanted to switch ROMs. So I went into safestrap, wiped everything but SD, and realized I deleted the desired ROM by doing so. So, I just flashed a backup to get back to where I Was, but accidentally flashed a backup which ONLY had "data" on it, not "system" as well. So my phone wouldn't boot.

After much research, I was able to use ODIN to flash "AP_I337UCUEMK2_1921628_REV06_user_low_ship_MULTI_CERT". This got me back to stock (but the settings still show it as NC1, and 4.3". Then I rooted again using KingoRoot, got safestrap 3.72 again, and tried to flash the RIGHT backup this time....but it got stuck on the Samsung Logo (not the one with an unlock logo on it, but the one that comes AFTER the option to safestrap). I tried to wipe everything except SD card and start fresh by installing a ROM instead of restoring a backup, and same thing happened. Stuck on SAMSUNG screen.

Now I flashed AP_I337UCUEMK2_1921628_REV06_user_low_ship_MULTI_CERT via ODIN again but would like to get back to using SafeStrap again...what do I need to do from here? Am I just using the wrong ODIN AP file? Note, even though that file says MK2 my About Device shows NC1.

Tmobile is GSM only. Look for model number "m919". You probably won't have much luck buying motherboard only, so a broken screen phone is a better bet. Just stay away from bad imei or "phone does not power on".

1. Copy Files to ExtSdCard

-- ROM install zip file

-- ATT Kernel Modules zip

-- UPDATE-SuperSU.zip

2. Reboot into Safestrap and Wipe

Wipe --> Advanced Wipe --> check everything except extSdCard*

3. Install ROM Zip

Check ROM notes... may need to replace updater-script

4. Install ATT Kernel Modules

Modules must match the kernel you are running and can be found*here.

NJ4 base users, flashATT_NJ4_Modules.zip

NI1 base users, flash*ATT_NI1_Modules.zip

NC1 base users, flashATT_NC1_Modules.zip

NB1 base users, flashATT_NB1_Modules.zip

5. Install SuperSu.zip

6. Reboot

Noob Question

Hello everyone... new here and not even sure if this is where i should post so apologies beforehand....

I have a galaxy S4 i9500 its an AT+T phone but im using it in the UK on the GiffGaff network ie... O2.....

I would like to root the phone i could see the detailed instructioncs but it mentioned something about bootloader so i believe i cant use that specific root can anyone please direct me to the correct rooting method...

Many thanks

CKKONE
[AT&T Samsung Galaxy S 4 General] guut13:
First thing's first. You need to figure out what phone you have. the S4 i9500 is not the ATT phone.

i9500 is the International S4 with an Exynos processor.

i9505 is the International S4 with a Qualcomm processor.

sgh-i337 is the ATT model with a Qualcomm processor.

1. Of the 3, sgh-i337 is the only one with a locked bootloader

2. Because of the different processors, the i337 is only compatible with most of the ROMs made for the i9505. (check post 2 for the complete list). It is compatible with ZERO ROMs made for the i9500. Does that mean the root methods would be different, too? No clue. I do not have one.

If you do have the i9500, your best bet is to check the general Galaxy S4 forums for i9500 info... http://xdaforums.com/galaxy-s4

If you have the ATT i337, then these instructions will help you out...

MTP does not work, as is, because of the kernel incompatibility. You need to use a 3rd party app.
