I installed Quick Boot and am trying to go into Bootloader It's been downloading for about 15 minutes. It says "Do not turn target off. "

Pulled the battery and it booted normally. Tried to go into recovery through Quick Boot but still ended up at the Android recovery screen.
[AT&T Samsung Galaxy S 4 General] :
I don't ever go into bootloader with s4, nothing I can do there anyway. That is where you went for fastboot etc. We can't use that. You don't have a custom recovery anymore it seems. Using Quick Boot means you are still rooted. Don't think you can flash a custom recovery from stock recovery. I forget--maybe someone can answer that. If so, I have one to flash. Or, re-root with Motochopper and it installs custom recovery--TWRP. Not sure if you need to Odin back to stock first. Someone will give you the exact answer soon.
[AT&T Samsung Galaxy S 4 General] NHComp:
[QUOTE=You don't have a custom recovery anymore it seems.

That's what I was thinking too, though ROM Manager and Quick Boot say it's there.

Thanks for your assistance...I'll try again

Update or not

Got my daughter this phone, ATT i337. Bought a good one off craigslist. The guy who had it never updated from ATT so it is still on 4.2.2 with the MF3. My question is should I update and then root and do a custom ROM or is it better with the current settings. It is carrier unlocked, and I assume an update will not lose that (it was unlocked by ATT according to him and I cannot see where it has been altered in any way).

I have flashed HTC phones a lot and have experience with recovery and such from them and from Kindle Fire products, so while no where near an expert, I am not a newb either.

Thanks in advance.
[AT&T Samsung Galaxy S 4 General] manstable:
I would definitively find out whether or not the bootloader is locked on your phone. If it's unlocked, I would root, then load a custom ROM/kernel. At the least, I would definitely use a full-fledged custom recovery.

I have a locked bootloader on mine, and took OTA updates to NB1 at which point I rooted, and hacked-together the ability to load custom TW-based ROMs via SafeStrap. I really wish I was able to load a different kernel and AOSP based custom ROMs.
[AT&T Samsung Galaxy S 4 General] :
All S4 bootloaders ARE locked. Only MDL builds have the loki-doki exploit to flash custom roms/kernels/recoveries. Anything above that needs SafeStrap. With MF3 you can only flash TW 4.3 roms. With NB1/NC1 you can flash 4.4 roms. So, I would upgrade. But, it is more complicated than your previous phone. Check out All Things MK2 etc and SafeStrap threads in General and SafeStrap thread in Dev Section to get very familiar on how to go about it. Good Luck. :good::)

**YOU CAN NOT FLASH CUSTOM RECOVERIES OR KERNELS**

I have an AT&T I337 NC1. I have heard that Safestrap works fine on this model/version, but cannot find the proper download. The main Safestrap topic in this board says to make sure to use the correct version, but doesn't have my version listed...

[AT&T Samsung Galaxy S 4 General] NHComp:
Have a ATT S4, rooted, MDB baseband, 3.4.0-440216 kernel (went back to 4.2.2 but had a CM ROM on it some time ago). I had used Superuser successfully, then started getting "Superuser stopped" messages. Uninstalled it and now have SuperSU which appears to be doing better (no error messages). Have tried ROM Manager and TWRP Manager. Both download the recent versions but they always boot into Android recovery instead of the custom recovery.

1. Any idea what's wrong?

2. TB confirms I'm rooted....do I have to use a custom recovery or can I wipe and install Skyfall?

Got a phone with MK2 on it, don't really care about upgrading, but i can't get WiFi to work, just shuts off -- i've read i need to install the modules, i have safestrap 3.71 installed, and i've tried these modules here -- http://xdaforums.com/devdb/project/dl/?id=3275

but wifi still doesn't work -- baseband is mk2, and i've read as long as baseband matches build number i should be fine, but i'm not.

Thanks in advance.
[AT&T Samsung Galaxy S 4 General] :
If you go to mdl, which I have, you will still be able to flash custom roms and recoveries.

If you get mdl on phone, you can use MottoChopper to root and it will flash TWRP. Not sure which one, but i like 2.5.0.2. There is flashable zip for it.

I don't think you can flash later roms w/o going to MDL first. But, not sure--someone needs to confirm. iB roms like SkyFall have an Aroma installer to pick which phone version you have. But, I am not familiar with running SkyFall. You will not want to do anything SafeStrap related it is only for builds later than MDL.

Not, sure either if MDL will solve your problems. But, you should update. I don't have link for an update tar. Calling it a night. Check in General for it. Or, someone may link you. I would only Odin a tar from xda or Sammy website.

Backup first--:good:

[AT&T Samsung Galaxy S 4 General] DeadlySin9:
For the record, any ROM should be flashable on MDB or MDL. There should be an update tar at sammobile.com to use with ODIN. No harm can really come from updating as long as you use CASUAL to root and then freeze the update apk's or install a ROM.

Good to know. I just thought I remembered something way back when a dev mentioned you needed to be on mdl to flash his rom--wasn't sure on that though--:)
[AT&T Samsung Galaxy S 4 General] NHComp:
I was rooted and running a CM ROM some time ago. Then confused myself and just to be safe went back to stock before starting over. Now I can't boot to a custom recovery. Does that mean the bootloader got locked again? Should I just start over (re-root and follow the procedure in the noob thread)?
[AT&T Samsung Galaxy S 4 General] :
If you were running CM you had either MDB or MDL build. The only way that changed was to take an update. What is your current build version. If above MDL you will need to got All Things ATT/MK2 etc and get familiar with SafeStrap. Your bootloader was and always will be locked. We were just able, on mDL, to the exploit loki-doki to bypass it. :)
[AT&T Samsung Galaxy S 4 General] NHComp:
I'm on MDB so I shouldn't have to use SafeStrap. Titanium Backup, ROM Manager, & TWRP Manager all say I'm rooted, and I have the latest recovery. Then when I boot into recovery it goes to Android recovery. I appreciate everyone's patience in assisting me.
[AT&T Samsung Galaxy S 4 General] DeadlySin9:
Did you use CASUAL? I'd just say try reflashing it but I don't know why it would mess up.

[AT&T Samsung Galaxy S 4 General] bender394:
First off let me say thank you to EVERYONE who has posted on here. I have found it very helpful and have learned a lot.

I do want to ask a question because I am a little confused by conflicting information. I would like to flash foxhound rom on my device which is built for i9505. I have read that I can flash this on my Canadian i337m device. Where the conflict is revolves around the Kernel, modem, and bootloader.

I am already rooted with TWRP installed and from what I understand, my bootloader is not locked down so do I need to update as the install instructions suggest? They also say I should update the modems both using Odin

the provided bootloader is BL_I9505XXUFNAD_481100_REV06_user_low_ship_MULTI_C ERT.tar.md5

Provided Modem is I9505XXUFNC9_GSM_LTE_Modems.tar

My device:

Model SGH-i337m

android 4.4.2

baseband version i337mvlufne1

Kernel version 3.4.0-1529758

build number KOT49H.i337mvlufne1

carrier is Rogers

Does flashing ROMs change the modem or Kernel? I know you can flash these individually but is also included in the ROM?

Thanks again

Ok guys, have been on these forums for hours but I am still lost.

I have a Samsung Galaxy S4, ATT, 4.2.2, I337UCUAMF3, rooted.

I am wanting to flash the 4.4.4 (or whatever the latest android version is) google edition / pure nexus ROM if this is possible.

From what I have read, I know that I need to flash a custom recovery first. Do I use safestrap? But I am not sure how to do this.

Can anyone please link me to the guide that I need for my phone.
[AT&T Samsung Galaxy S 4 General] :

Ok sorry for the confusion. All the roms from this forum, the T-Mobile forum, and the 9505 forums are compatible as far as I know. If you have a phone with unlocked boot loader you can just flash the Rom and then flash a kernel that works with your device and it should work. Check out the thread I linked to in the Loki section for more concrete examples. Hope this helps.
[AT&T Samsung Galaxy S 4 General] Rastabolino:
Apn settings are found under system settings - more networks- mobile networks -access point names. You will need to track down the apn for your carrier and input that info. :)

I have had my SGS4 for over a month now and have been reading on xda everyday since your OP has already answered alot of questions for me, thanks! I still have not built up the courage to flash any custom roms yet since i still have questions and dont wanna brick my phone.

1) I am running CWM recovery, does this mean my bootloader is unlocked? How can you check if your bootloader is unlocked?

2) From my understanding once it IS unlocked you can flash most of the custom roms out there. Am i correct on this or way off?

3) Why would you ever want to flash a different modem/radio? It seems to me the modem is location specific.

Im sure any answers will just be followed by more questions :)

What app should I get to back up my info before I root my phone?
[AT&T Samsung Galaxy S 4 General] Rastabolino:
1. your bootloader is locked if you have an ATT or Verizon phone. I believe all the other carriers are unlocked. If you have CWM on your phone that means you have custom recovery...if you have a custom recovery on ATT or Verizon phone it means that you have successfully bypassed the bootloader lock via loki patch whether you knew it or not...however, at this time there is still no way to actually unlock the bootloader. (for all practical purposes though you could consider your bootloader unlocked once you have a custom recovery, you just still need to make sure and loki any roms/kernels you use if they arent already

2. Once you have a custom recovery, you can flash most custom roms out there. If you are using the auto-loki version of CWM this is even easier

3. As companies release updates for the phones, they sometimes update the radio for the phone. Users have found that sometimes a particular version of a radio works better in their home area than others, so they may want to revert back to a previous version that worked better...
[AT&T Samsung Galaxy S 4 General] Rastabolino:
This is outside of my area of knowledge as I don't know how the carriers work in Hong Kong...However, my guess is that maybe your carrier did not enable the LTE bands on your phone yet. If you search for AWS in the forums you may find a way to open up the other bands...there is a guide in these forums for it, just be very careful as you could really mess up your phone if you do the wrong thing..

Good luck
[AT&T Samsung Galaxy S 4 General] Rastabolino:
There really isn't any app that can backup your phone before you have root. Rooting should not erase any of your data, at least not the ways listed in these forums. If you want to backup a few things like call log and sms messages, then sms backup + should work, it syncs to your gmail account. Once you have root, there are lots of programs that do backups, the most common is titanium backup.
[AT&T Samsung Galaxy S 4 General] LuigiBull23:
Or flashing a custom recovery then backing up his phone before rooting would be a good route to take as well in case he's worried he'll lose his personal stuff
[AT&T Samsung Galaxy S 4 General] Rastabolino:
It is impossible to flash a custom recovery without rooting...at least if you are on a phone with a locked bootloader...I guess if you have an unlocked version of the phone you may be able to flash a recovery without root access. Still, once you root and get a custom recovery the first thing you should do is backup using the recovery and also copy that backup to your computer or some external storage so that you can retrieve it if you ever accidentally delete it off your phone
[AT&T Samsung Galaxy S 4 General] LuigiBull23:
True.. but I was speaking in general terms anyways just so he's aware lol but that is correct. If the bootloader is locked down then no recovery which means no backup can be done. The best thing I'd recommend is using MyBackup Pro. You will lose out on the root features but you can still backup most the important stuff.

I have the canadian version (I337m), which if im not mistaken comes with the bootloader unlocked already. If i am to flash a new rom/kernal do i still need to loki them? And if not, then is it still okay to flash a new rom/kernal which have been loki's already??
[AT&T Samsung Galaxy S 4 General] Rastabolino:
You need to use either the "phone" apn or the "PTA" apn to get LTE

the phone apn is the easiest to use. Just add a new apn, and under APN enter "phone" then save...that should work. I will try and find the PTA setting soon but i know they are somewhere in this forum

good luck :cowboy:
[AT&T Samsung Galaxy S 4 General] Rastabolino:
You don't need to Loki if you are on Canadian version...you also cannot use a LOKI rom/kernel if you are on Canadian version. If you flash a rom that is LOKI'd you will need to flash a kernel compatible with your phone before booting...so you would go to recovery, flash rom, flash your kernel, reboot.

Sequence and Reversal....

Just got my new S4 from ATT USA. It is a SGH-I337, 4.2.2, Kernel 3.4.0-453947

I want to unlock it and root it to be able to use some apps that requires it. Not yet interested in a different ROM

ATT should give me the unlock code as I'm with them for more than 10 years and they supplied the unlock for my previous phones. Now the questions:

a) Is there any better sequence to use? Unlock -> Root or Root -> Unlock:confused:

b) Is the root reversible if there is any issue during the procedure? Can you guys point me to one that is working with ATT 337's?

Restoring any data from any back up also waves all your right to support. Please don't bother posting in the thread!

Modifying lock screen?

Let me preface this with an apology. I am very new to Android, but I'm very excited about the possibilities. I have tried close to every ROM listed for the i337 and a handful from the i9505 forums. There are features that I really enjoy between the different ROMs and ideas that I'd like to try to incorporate once I get up to speed. I'm a huge fan of the work done on the GE firmware, but I also absolutely love the lockscreen of the CM10.1. CM will likely end up being my daily driver once more of the kinks are worked out. But in the mean time, my question is this: is it possible to port the CM10.1 lock screen over to a GE-based firmware?
