aosp lte issue - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I have no idea why this seems only to be happening to my phone... I get zero 4g despite my phone showing 4g. I have updated profile and prl in tw... I have tried twrp and cwm. I just can't get 4g on a aosp ROM. Any help would be appreciated. Both screen shots show speed tests in the same place while I was at work.

It's been known that aosp in Many cases causes this. My last phone epic 4g touch was the same way. Flash stock rom and data speeds back to normal

I have had issues with aosp when I would dirty flash. I'm currently running Carbon and 4g is running great. Just try a clean install. Could also consider that we are mostly on nightlys and unofficial releases. No telling as of yet but I'm getting pretty good speeds on Carbon

I always do a full wipe before I flash a aosp ROM.. I seem to be the only one on the forums having this issue. the only thing I can think of is a bad modem. Haven't found a flashable modem so I may unroot odin stock and reroot and see what that gets me. I only run aosp roms on all my phones...this is killing me

From what I understand we can't flash modems yet. Are you on MDL or MDC? I have had issues with the modem on TW after unrooting on MDL, but they were fixed when I reinstalled the update from Sprint.
Not really sure how the radios interact with AOSP, but could have something to do with the differences between the update.

If I root my Nexus S.

So I'm thinking about rooting my Nexus S and keeping the stock rom, now my question is if I do root will I not receive the OTA update for ICS or will I still get it?

A little reading wouldn't have hurt............
Anyways, if you do not modify anything in /system then you should be fine. I wouldn't ever be worried about receiving an ota anyways. Chances are someone will post the full rom here before your phone ever recieves the ota notification.
Sent from my Nexus S 4G using xda premium
Thanks for the fast reply, I new I was going to get hit with the not reading part, but rooting was something I thought of on an impulse and I did as much reading as I could before I got into work so I thought I would ask for a quick answer. Now that I have the answer I have a lot more reading to do before I even try to root.
Thank you again for the answer.

You WILL get the OTA update
Guys sorry if this a noob question. But I just recently rooted as well .
I'm running stock rom and francos kernel. Will stock rom and diff kernel mess up if you accept ota?
I'm also looking at trying diff kernels like trinity teuv.
I know I have to wipe cache and dalvik when flashing another kernel however some state to reflash the rom as well. I'm on stock so nothing to really reflash . What steps should I take to make sure kernels don't conflict.

I've had wifi driver issues when flashing kernel outside of rom flash also, sometimes it works fine, other times I get the wifi error. Do not update ota if your using a custom kernel and recovery, you must be 100% stock to do so. There are stock flashable roms however, google peter Alfonso, his stuff is in rom manager as well. Also bugless beast is a stock based rom with many improvements, very stable also. Perhaps check it out.

Always disable wifi before flashing a rom. In fact putting your device into airplane mode is the safest bet.

I'm not saying that's not good advice but I have done both and still had the error, but I'm sure it doesn't hurt.

If you're rooted, most likely you will not get the OTA notification. That's not a big deal. When ICS hits, it's going to hit here just as quick if not quicker. You'll most likely get an error if you try to flash an official OTA on a rooted device, has to be stock.
Btw, Oxygen is my ROM of choice, so I await his ICS 4.0 ROM anyway. Heck with the OTA.

So I rooted today, before I rooted I was on 2.3.7 after I rooted I was on 2.3.4 and it told me there was an update, so I took the update the screen went black showed the picture of the Android with a ! Next to it, after about an hour I pulled the batter and when I booted back I was still on 2.3.4 and it no longer says I have an update.

Help with RandomROM Thunderhawk 3.3

Okay folks, if somebody could bring my issue to the attention of anybody who knows what to do about it I would appreciate it.
My issue is twofold:
1)I'm still getting random reboots with RandomROM Thunderhawk 3.3 despite the posting on the thread that says (NO MORE REBOOTS) Is there anything that can be done about this?
2)I checked my baseband version and the modem is still EC05, is there a way to flash or ODIN an EI22 modem for this ROM without getting a black screen when the icons should come up? Could this also be what's causing the reboots?
Thanks for anybody's help that is willing to give it.
Are you using a custom theme? And you have to flash the stickied modem delta. If you are using a theme, I would blame that.
Sent from my ICS NookColor using Tapatalk
I was using thunderhawk too and I had some reboots but onlyyyyy on the lockmod version. When I flashed the regular one I had no problems at all
And for basband I would probably try this
Nandroid backup
Flash "ec05 to ei22" its somewhere in the development section I believe
Reboot
If that doesn't work then a fresh new start is what I would Recommend
Odin back to stock
Root
Install cwm
Flash "eco5 to ei22" modem
Flash thunderhawk 3.3 (without lockmod if you could live without it)
Sent from my SPH-D700 using XDA App
I got the EI22 modem here and flashed it in CWM and it worked well. Only problem I had with thunderhawk is the lockscreen mod, and I'm having data issues on wifi after the phone's been on a while.
I was ec05 but when I flashed the Thunderhawk and it changed to ei22. never had a problem. Got a wild hair up my butt to flash the shadow kernal 1.0.6. Never been happier. no reboots, wifi works perfect, and very responsive. running a live wall paper and still get awesome battery life. give it a try
I saw several posts from folks having some wifi-4g interaction problems...switching back and forth causing one or the other to fail...is that a common problem to all 3.3 users, or are most people not seeing it? I want to give this a try, but I use 4g (at work) and wifi (home) everyday, so I'd like to see how common that issue is. I'm currently on Mostly-stock with Nubernel's latest released kernel...
Sent from my SPH-D700 using XDA App
So...bummer. I guess I answered my own question...I installed Thunderhead 3.4.3 and sure enough... I have wifi and 4g problems. Seems like going back and forth between the two causes issues...had it fail going both ways today. On a positive...man, that ROM seems pretty nice and his new install process rocks...was seamless going from Mostly Stock...
Sent from my SPH-D700 using XDA App
You could always try a clean install with doing a factory data reset in CWM and wiping Dalvik, flash ROM, check to see if stuff works, then do an advanced data restore from your last nandroid. If you stll have problems then the best bet is to set everything up fresh after the clean install.

The deal with the wifi/4g issue is that 4g will show 0.0.0.0 for ip, baseband, and dns if used after wifi in most cases. This is on official releases of 3.3 and newer. If you turn off wifi, reboot, then turn on 4g it should work. This is oviously annoying. Random provided me with alpha builds of 3.4 and 4.0, and the issue was squashed for me. However, the issue still persists in 3.4.3 official release according to some reports. I have limited access to 4g and can only test on certain days.
Thunderhawk is in a transitional period right now, and 3.4.5 should be released today. Random is hopeful this might solve some issues, including the dialer issues some are reporting with the 3.4 official builds. After that his focus will be on 4.0, which is EL30 based. Consider anything from 3.4 on a beta, and only run it if you want to help find bugs. Obviously you don't mind reporting or I wouldn't be replying lol. Just follow the threads and wait untill it looks stable enough for your usage needs.
Sent from my SPH-D700 using xda premium
Thanks! I certainly wasn't busting on Random's work...and I know he has limited access to 4g for testing, so that makes it harder for him to verify these things. So
I absolutely saw what you describe going from wifi to 4g. Going from
4g to wifi, I had wifi that wouldn't turn on at all (error when trying to enable), and, like you and others have mentioned, a reboot resolved both cases. I will hang out and see if he pushes out a fix soon, and just eagerly await 4.0. If it gets too annoying, I'll restore to my
Mostly Stock... Hmmm... Is there an issue restoring an rfs backup if I am now on ext4? Heh...

cm10 internet problems.

I recently installed cm10 on my new s4 but the 3g speeds are really slow. WiFi is slow too. I saw a forum with the same problem with the HTC one. They said it was a problem with the baseband. Any help would be great because I'm not a huge fan of the stock os even though the internet runs great on it.
anyone know of any basebands that work. I would appreciate any help

You could always try to go to a Touchwiz Rom, update the prl and profile, and then flash back to cm10. I've heard that can speed up data a bit
You also could try flashing the MDL modem with Cm10...that might help as well http://forum.xda-developers.com/showthread.php?t=2338919

I don't think updating in the stock rom will have any affect since the internet on the stock rom runs fine. It's only after I install cm10 that the internet starts to bog down.

I did the odin thing and now my stock rom can't use wifi. When I enable it it says an app is trying to get certain permissions and wifi immediately gets disabled. It tells me to reboot the phone and I do so and same problem occurs. I did come to find that when on cm10 the internet does work but the play store and pandora only work on wifi. I get connection errors on 3g with those two apps.
Try to flash a custom kernel or flash a different AOSP ROM.

Not sure why the kernel would affect it. I was trying to find an aokp version that would work for sprint but couldn't find one.
It could help the WiFi issues because when my WiFi wouldn't work I flashed a custom kernel and it would work.

Oh you mean for the stock rom? I don't want to use the stock ROM if I can get the play store and Pandora working on cm10. The stock ROM is saying its a security issue and not just an error with the WiFi so I don't think that would help. The problem started after I installed the modem in Odin.
For both I also recommend checking out that ROM it seems like what you want in a ROM customization, AOSP, and the stabability of CM. Here is the link http://forum.xda-developers.com/showthread.php?t=2312063 if not check the original android development section it is filled with great AOSP roms similar to CM or better.

There is many cases that aosp roms/kernals have slow data speeds. The epic 4g touch was one. All aosp or touchwiz roms with non stock kernal had poor data speeds. This phone may be different. Im running tw rom with kt kernal and data speeds are the same. The prl/profile thing is huge not being able to update it in aosp can cause problems.
I installed pacman ROM and the gapps and Google play immediately stops working and a message pops up every 5 seconds and the internet won't load. I got Google to load once and that was it. I had to switch back to cm10.

Just coming back to the s4 after being gone about a month

Hello all. As I wrote in my title, I'm just coming back to the s4 after being gone for about a month. I've flashed a few roms and I've noticed that data stops working on almost all the ones I've tried. I tried the Google edition and flashed a different kernel to get WiFi working--when I did WiFi worked but data was broken. Then I tried tri force, data did not work. Finally I tried the one with the weird name (sorry--I know that doesn't help much but I know viper appears in quite a few places in the thread). I am currently on liquid smooth (cm based 10.1) and thankfully it's flawless. I love it but I like variety and I wish I could find a debloated TW rom to play around with. Why it's the data borked on so many of them? I'm not exactly a noob--been an android user for years and I've flashed many a roms. I don't think I'm doing anything wrong, unless there's something different or weird with the s4. Can anyone kindly shed some light on my predicament? I'm now downloading negalite. Gonna see if that one has functioning data. It almost seems as tho you have to flash a custom kernel all the time now to get data. Is this right? Thanks in advance!

I have no idea why as I've tried everything I can think of and read but aosp runs better on my S4 than tw, as crazy as that sounds its been true for me. I love Aosp so I'm good. I'm on mf9 via otas and tried all recoveries made and always end up with some type of system or phone fc or the "detected an app".. .blah blah warning which annoys the crap outa me so I just stay on aosp as there are a ton of great ones for us and they work wonderfully -the once in a while call bug which I do not come across that much really ams when I do I made a shortcut for fast reboot via rom toolbox and just hit it when it happens and its good.

Just FYI.....If you flash a TW MF9 rom with the stock kernel and WiFi is broken after boot (can and has happened with Negalite, TriForce, etc) there is a modified stock kernel that can be flashed to fix if needed.

I must be lucky, because I have had no such issues with any rom (AOSP or TW). If I flash the stock rooted MF9 rom followed by the stock MF9 kernel, I have wifi and data. Same goes for any other TW rom as well as every AOSP rom I've tried.

[Q] Losing LTE with custom ROMS

I'm posting this here because I don't have enough credits to post in the development forum. I've been installing various custom roms on my Sprint Galaxy S4 (Carbon, Sacs, to name a few). The ROMs seem to be working fine except for the fact that the phone will not connect over LTE, only 3G. I've tried all sorts of kernel/ROM combinations, profile updates, PRL updates, but when I restore to my MF9 backup, 4G comes back.
Can anyone confirm that it's possible to connect to LTE with a custom ROM.
I am running Sacs v7.2. I only have patches of 4G where I live, but when I get into one of those areas, it works fine.

Thanks. That's interesting. I was most recently trying Sacs. I started with a stock MF9. I rooted it with CF auto, installed TWRP 2.6.3.0, and flashed Sacs. Right then, 4G stopped.
