WiFi problems with Touch Wiz Roms - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I restored my Galaxy S4 after I was getting hung up at the Custom splash screen. But since using Odin to fix my phone, the WiFi on Touch Wiz is broken. I've tried Golden Eye, MDOB, and some of the T-Mobile ports but to no avail. AOSP works perfectly with WiFi though. Any thoughts?

MIUI troubles

I've been running the MIUI port on my s4 for a couple days now. And everything is working flawlessly. But when I flash Ktoonz Kernel I have constant boot loops or it stays at the start up logo. Any help with this?

Now I may be wrong here, but I am friends with someone who runs the S3 miui and has done it for various devices now. I believe I read in his 4.2.2 builds that the kernel could not be changed on miui currently because the framework was highly dependent on it. It may just be an issue on the s3 though. Hope this helps.

Thank you. I feel like that would be correct since it just sits at the Mi start up. I hope they fix it.

Trouble with phone after flashing.

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.

ok ill try th

Vs980 where to go from here?

I finally decided to drop my beloved galaxy nexus. The N5 seemed like the next phone of my dreams but couldn't stand the thought of losing my unlimited plan so G2 seemed like the next logical choice. I have been reading as much as I can and still having a hard time wrapping my head around things. Here is where I am at:
Bought phone from swappa appeared to be in new condition as advertised with plastic still on the phone.
Not sure if the phone was updated ota by the seller but the software and baseband were 12b out the box not rooted.
I rooted successfully with latest I0root method.
Installed loki patched twrp 2.6.3.3 successfully via freegee method. Full nand backup of rooted stock. Backed up imie with freegee and imie and other partitions via flashable zip method.
So where do I go from here? Is it safe to flash any VS980 rom from this point?

I have yet to install a custom rom or I could let you know. I have however upgraded to philz recovery and successfully installed dorimanx kernels. Got a little busy messing with exposed modules as well. I wanted to make sure I have all my essentials backed up before messing with roms and have the appropriate files and drivers working in case something goes wrong. I tried to install malladus yesterday and the install failed but I want to say the download was bad as it took forever. I had no issues with restore. I'll report back if I have any luck.

If you want some KitKat love, try out Mahdi ROM with the latest furnace kernel. Very very stable on my vs980.

You've bought the right device, aside from some unreleased phone of course. I too came from the gnex and I love this thing. Go install some AOSP ROM and it will be like you never left the gnex. (Although admittedly not as stable YET). With KK just being released by LG, all roms should get better. Anyways, enjoy a camera that works all the time not just when it is super bright and a battery that is equal to 3x of the galaxy nexus.

Thanks for the input. I installed AICP latest ROM last night with no issues. Feels amazing with no scroll lag compared to stock. Only thing I miss is knock off but hey you can't have it all. Gonna give furnace a go later.

Unlocked AT&T Galaxy S4 not working properly

My fried bought a Galaxy S4 from AT&T when he was in US. While leaving the country he bought an unlock code from AT&T and unlocked the phone using the same in India. His phone was working fine initially. Then sudden signal loss started to occur and need to restart the phone to get the signal back. Tried using different Indian carriers and the same issue continued. Will I be able to solve this issue by flashing a custom rom into his phone? Do I need to take care of anything else, like the modem firmware or something. Attaching a screen shot of his phone details. Please help guys..

You could try reflashing the same MDL firmware first. If that doesn't work, then install TWRP and try the different flashable modems.

Thank you for the reply.. However we have already tried a factory reset.. Will it be a problem if I flash the modem firmware available in the Indian Galaxy S4?? The Indian version comes with an exynos octa processor instead of the Qualcomm one..

Doing a factory reset is different from reflashing the firmware. I don't think the other modems would work, but I'm not entirely sure. If they're recovery zips you could try, but if they're ODIN files it definitely won't work.

I have tried reflashing the phone with Odin. The device now has the latest Android 4.4.2 firmware from AT&T. It seemed to work fine after flashing. We got the network and were able to make calls as well. However after sometime the signal got cutoff itself. Tried flashing again, the same thing happens. Any other suggestions??
