Trouble with phone after flashing. - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

So I have been flashing Roms since this phone has had the ability to. But recently I decided to flash a Google 4.2.2 ROM. Well, I can't flash any ROM except for Google 4.2.2 or 4.3 and its frustrating because I want to go back to AOKP. Any ideas how to fix this?

Also. To further clear it up. When I flash another ROM the phone sticks at the custom screen. Doesn't bootloop, doesn't shut off. Just sits there.

Which rom have you tried to flash? Also which S4 do you have?

Flash the rom back you wanted, and before you boot, FLASH THE AOSP ATT KERNEL FOR YOUR DEVICE. It will boot.
You did say aosp you wanted to go back to, if it is a TW rom, flash tw.
Thank you. Your Welcome.

Everything from Goldeneye to AOKP. But it just sits at the custom screen. And I have the I337 AT&T US.

I flash AOKP with the stock underwear kernel. I don't think that flashing the AOSP att kernel would effect it though. I've never ran into this problem with my past 3 phones. EVO 4G, EVO 4G LTE, and my SIII

You also didn't have locked bootloader on the others.
if you do not use loki doki or loki kernel, you will continue to hang at the boot screen.

Good point. I forgot about that.

[Q] Flashing wrong kernel?

Hi XDA.
After growing a pair of balls I've decided tonight is the night that I am going to unroot my phone, put it back to stock ROM and get it off of franco.Kernel. I am doing this because I want to start fresh and get it on Paranoid Android.
(I currently have a January nightly of CM 10.1, franco.Kernel r53 and unlocked bootloader whatnot)
I am looking for the stock kernel for the Nexus 4, but am worried about flashing the wrong one. I'm not saying like I'm going to flash a Samsung kernel or something stupid like that, I just mean that since I am on android 4.2.1 and if I flash a kernel that is made for android 4.2 can I screw up my Nexus 4?
Any tips?
Thanks a ton.
Edwin
As long as the kernel is for the Nexus 4 then you should be okay. You can get all the resources here.

Just flash the stock images from Google. Contains rom, kernel, bootloader, and radio.

make sure your download isn't corrupted and you downloaded for the correct device. Should be fine.
What's the point of going through all the time to unroot and flash back to stock?
Why not just do a full wipe and flash paranoid android?

I was wondering how nobody else asked that question earlier because that's exactly what I'm thinking.
He's going from 4.1 to 4.2 he needs to flash the new bootloader and radio too

I have heard of the digitizer blowing from flashing wrong kernels. I suggest only flashing kernels made for your specific device.
Sent from my Nexus 4 using xda app-developers app
You should add one more ball to that actually make it two more as you are at it. First you should install latest cwm recovery and root your phone. Then go to the recovery and make a backup. After that you can continue with flashing custom Roms and kernels.

Of course there is an untouched GE 4.3 ROM. Just download it from here:
http://forum.xda-developers.com/showthread.php?t=2395030
It's from the i9505 forum, but it is the same phone, and works fine. I am running it myself.
Just make sure you already have a custom recovery on the i337 first. I prefer CWM because it auto loki's your ROMs for you.

Android 4.3 Touchwiz ROM ANYONE??

Does anyone know of a new Android 4.3 Touchwiz ROM? 4.3 has recently been released on the GT-I9505 and I have been wondering if anyone has implemented this into their ROMs yet. I'll probably just flash a Loki patch if it isn't already loki'd.
Anyone have a suggestion or idea? Comment below!

I have already tried flashing the VisionX II on my ATT MF3 S4 with no luck. ROM tries to flash and returns success but progress bar never fills. I flashed the Knootz kernel with no help there either. Upon re-boot, phone passes thru Safestrap and then black screen and goes no further. Like to know if anyone has been able to flash the new VisionX v4.3 and what I did wrong if anything.

Did you flash a loki patch? Remember that it's made for the I9505 and not the I337
Sent from my GT-I9505 using XDA Premium 4 mobile app
You don't need to flash loki if you flash the att ktoonz kernel. I did not use safe strap so I cannot answer that question but with twrp I was able to successfully flash vision I I. This rom is amazing and really fast. If you can I suggest you give it a shot.
Sent from my GT-I9505 using xda app-developers app
I've done so, but with Philz touch. It didn't work though, as it just gave me a black screen after it booted, and then otherwise just kept rebooting without even continuing with a boot animation. I did flash Loki doki, but do you think it would make a difference if I were to flash the AT&T kernel itself?
Sent from my GT-I9505G using XDA Premium 4 mobile app
All I did was factory reset then flashed the rom and then flashed the ktoonz att kernel. Then wiped cache and dalvik and rebooted. Works perfectly...you don't need to mess with loki if you flash an att kernel as they already have it.
Sent from my GT-I9505 using xda app-developers app
Ah yeah. I've actually done so before I read this message and I have it running on my phone right now. I want to get mobile data to work though, and so far it's not going anywhere. I've even given it the right APN, but I guess it's just not showing up when I turn it on. Have you had problems/solutions towards this?

Yes I have mobile data to work. I entered the right apn (ATT PHONE) and then saved it. Also I changed the network mode to lte/wcdma/gsm. I've heard the new audism 4.3 kernel works very well but I have yet to have a problem with ktoonz and have amazing battery life.

[Q] How can I flash Cyanogen?

I have an S4 running 4.2.2 and it's currently rooted. But the root does not allow me to have a custom recovery. I want to be able to flash Cyanogen, but I'm not able to at the current time. What is your best idea of what I should do?

Then reread the OP and make sure you do exactly what it states.
Take your time and just make sure to follow each step.
MF3 can be rooted and de bloated but has no real custom recovery.
Safe strap only allows one on 4.3 to flash 4.2 2 roms.

I'm on 4.2.2 and I followed all the instructions very carefully, but whenever I try to load my slot with the Google edition ROM (4.2.2) the phone goes into a continuous boot loop. I have no idea what is wrong and I can't find a solution anywhere.

make sure you partition your slot big enough...try 2 and 1.5 for data...
