Hello XDA Developers,
I was trying to install a custom ROM on my Galaxy S4 deivce (SPH-L720). I successfully flashed the ROM through CWM. I installed the Google Edition ROM that was somewhere in the forums under Android Development.
But after reading the thread, it seemed that many people were have success with a kernel known as "AGAT".
After about 4-5 minutes of using the ROM, my signal and LTE went away, so I decided to flash that kernel as well. However, now I don't get any signal on any ROM. I flashed the stock kernel through Odin (I was trying to see if that would work), but no luck yet.
Any advice or tips?\
===================================================
UPDATE:
I restored it to the stock firmware and used TriangleAway. I took it to the Sprint store and the guy fixed it up for me in about 30 seconds.
Ya he probably just updated the prl and profile.

yup re activation was only way sprint tech over phone could fix it, if you know the dial code you can try it yourself...I also tryd the google edition rom with custom kernel which is what caused all this network lost, not even my stock rom nandroid back up could help me
Edit: heres the dial code for reactivation youl get data working again##72786#

Do you know how to install the AGAT kernel? I really want Google Edition, but I will wait if I have too.
You have to install the kernel right after flashing the rom...then wipe dalvik/cache and fix permissions. Worked great for me..

Does it matter whether it is on my sd card or if the kernel is located in my internal storage?

hi, this same thing happened to me and I've gone to 3 different sprint stores and none of them knew what I was talking about. my question is, how do you use the dial code you mentioned if the phone has no network connection? I've tried to go back and flash different rom's but nothing has worked. I'm using TWRP, AGAT 4.0, and the stable google rom. any help would be appreciated, I'm currently without a phone.

You're not *actually* calling anyone. It's sort of like command prompt for your PC. But instead of command prompt you use the dial pad It WILL work and it takes less than 30 seconds.

Hi guys, first of all let me share al my specs in order to place my question properly:
PHONE MODEL: Galaxy S4 SGH-I337M (the original stock kernel was: Build Date: 30.05.2013 -> Region: TCE (Mexico) PDA: I337MUMUAMDL Changelist: 518267 Android: 4.2.2)
Actual Rom: CyanogenMod -version: 10.2 10.2-20130923-nightly -jftlecan
Compilation number: cm_jfltecan-userdebug 4.3 JLS36G eng.jenkins.20130923.022829 test-keys
Recovery Mode: CWM via Rom Manager Pro app
So saying that I will say this: I came from stock to CM wiping Factory Reset and data/cache only and I used Odin for rootint the device....no problems at all, runs like a charm...
MY ISSUE #1: A couple of auto-updates ago (via Rom Manager), I start to notice that the radio bars (telephony signal, mobile internet signal bars) were from 1 to 2 bars in places I always get full bars (I live on a 7th floor with excelent signal at Mexico City). I searched on the forums (XDA developers and here) and it seems that ROOTED DEVICES SHOW THE REAL SIGNAL PROVIDED BY THE CAREER---->can someone confirm this? Is my phone showing the real signal strenght?, eventhough, keep reading to see that low signal bars are only the beginning...
So as i said, I didnt worry pretty much, because if the bars are little low, but i have a good quality service, who cares? but the REAL PROBLEM appears when another update came and when Im trying to use my mobile internet (4g or 3G, doesnt matter) the signal cuts exactly at the moment of loading a page or any info....it as happened with almost all apps (specially Facebook, Waze and Google Maps)
It happens as follows:
1.- Open any app, like Dolphin browser or Firefox
2.- Page starts to load info (LTE showing download and upload state)
3.- LTE-3G or whatever, shuts down (I see only the telephony signal bars and there is no internet signal)
4.- Wait few seconds, LTE-3G whatever is back...have to try again and agin until LTE remains steady (sometimes it wont until I reboot)
ISUE #2- DURING CALLS:
- Sometimes people cant hear me, but I can hear them...restart the phone and the issue fixes it self...buts is very annoying to restart my phone every single time somebody calls me and they cant hear me
I dont know what to do guys? Shall I wait until final CM10.2 comes to light? Somebody has this bug also? Is this bug part of CM? or there is another app making this rare behaivour...(do you recommend me another ROM for this model of GS4??)
EDIT: I tried to flash the original modem.bin (via ODIN) which is used by my carreer (TELCEL, son of Slim AKA "The richest man on Babylon :silly: is the company´s name). So until now, I can tell that in my first attempts of opening pages or facebook, the randomly LTE turning off-on continues...I will keep testing with this "orginal" flashed modem....

It's defiinitely a modem issue. You can flash new modems and try. (backup efs before doing so, actually if you dont already have one - do it before now and save yourself some grief)
If that's not fixing the issues...
I'd backup what you need and start fresh. It would be the easiest way to resolve all your issues. Maybe even try a different kernel set for your region and phone.
Kies has a useful firmware recovery option that sets you back to stock.
The Kies will use your model number and serial to get you your stock firmware and reset you back. Id wipe all data under settings then do it. After its done, do another factory reset in recovery.

Thanks for that advice, i guess Im going to do all that if a new kernel doesnt fix the issue (I havent found any kernel for my region which supports Android 4.3, only 4.2.2, and someone told me is not correct to install such a kernel). Good day to you!

So after done all the "back to stock" steps, I still get this questions:
1.- Would I still be ROOT but with stock firmware (Touchwiz) and cool features originally made for Samsung GS4? (such as air gestures, etc etc)
2.- If im "unrooted" by the steps described in your link, can I upgrade to 4.3???
Thanks you are so kind!
Check out GoldenEye ROM or MDOB ROM in the development forum. They are extremely stable, super fast, tw and excellent battery life. CM is awesome, but is seriously way to flawed for our S4's right now to use for day to day life.

Thanks. I successfully installed stock Rom (Touch Wiz) and the signal has been impecable (full vars and excellent internet speed). I have to say that stock Rom is faster than CM in its current state I'm having a better experience right now ( and didn't had the time to explore all the Samsung apps in their depth) thanks again for your kind help!!!

Well I just went back to original stock firm ware via Kies, and now the radio signal issues are gone!! CM 10.2 didn't work well for me as the stock rom is now working in my phone. Something tells me that some times it's better to just rooting (for enjoying cool apps as Greenify) and not installing custom Roms (because all this kernel carnival is just to much, and appart of all we have to install radio firmware? Just no!)

I have a SGH-I337M that I rooted with CF-AutoRoot and installed a few ROMs. I went back to stock for a bit and then installed a few more ROMS.
Now when I download my 4.4.2 firmware off Sammobile and install it with Odin, everything works, except my mobile data. My signal is good, I can send and recieve texts and make calls, but no internet. I tried setting my APN settings, selecting my carrier, restarting my phone, taking battery off and SIM, and still nothing. Not even Touchwiz custom ROMS work. it seems to be a TW issue. I have to keep CM11 on right now as my LTE works fine on it.
Anyone know what my issue is? My Modem now is NC1 with 4.4.2. Both with CM11 and stock. I tried calling Telus and they had no clue on their end. They tried refreshing my network profile and that didnt work either.

Install TW firmware and go to APNs then click menu button and then Reset to default. I had same problem and this little trick fix it.
Fixed it a different way. I used Odin to flash proper CS files but I ended up using the *#272#emei* method to switch to Telus and It worked perfect.

Hello,
I found this ROM to be great, operates really well but I have two problems.
Firstly, the LED notification indicator does not work at all, including when plugged in.
Secondly, whenever I enter my SD card into the phone it seems to be unable to mount. I receive the message "SDcard safe to remove now" almost as soon as I plugged it in like I unmounted it.
Any idea why?
Thanks.
The Best rom!
Hi! I have a question... Will be lollipop for us? This rom is amazing (Sorry for my bad english) LOL!
want lollipop for this phone!!
Note: problem solved with new update, clean installed.
I keep getting a random "updating camera firmware. Please wait.." message, I'm not even using the camera it just pops randomly when opening apps. Anyone know what's wrong . it takes at least 20 seconds till it stops popping up and disappears. I'm paranoid that I have an app that's taking photos and uploading them without me knowing.

No LTE on Kangapop 1.0
FYI -- Just clean flashed kangapop 1.0 -- and I got no LTE capabilities, even if I try to manually change it in cellular settings.
Tried both the loki'd googy and loki'd stock kernel -- no difference in behavior, still no LTE.
Otherwise a very promising ROM! Can't wait for version 1.1
[Kangapop] Can't get LTE on Rogers
Tried the select LTE and then reboot trick a few times and LTE still won't work. Anyone else having this issue? I am on Rogers.

Mine also has TWRP 2.8.0.1.

I did that too and it wasn't working. Until I started driving home and then suddenly it started working again. LTE is functioning again for me, but it took like an hour to find an LTE connection the first time.

Encryption
Has anyone been able to get the device encrypted after flashing this ROM? I am using the TWRP recovery and flashed the latest build after wiping everything instructed to. I picked the google loki kernel. When I try to encrypt I just get the new loading screen and it never begins the encryption process. After that it tells me that the encryption process failed and the only way to do anything at that point is to flash back to stock with Odin. I have been using CWM with the 4.4.4 ROMs and able was able to encrypt no problem. I did notice I wasn't able to encrypt using TWRP and the 4.4.4 9.0 Kangakat but I am able to encrypt using that same ROM and the CWM recovery. I hope I am doing something wrong. Any help would be appreciated and welcome. Thank you
Menu buttons on screen like a nexus phone, not using the samsung buttons?
Hi,
I fell in love in first sight with this rom! However, there is one thing I can't seem to figure out what I've done wrong (maybe it's because of the beer, lol..)
I have the default nexus buttons like if it was a Google phone. Here is what I tried so far :
I tried the Stock Google options, and the 2nd option for the Bell Canada available (not AT&T).
I would like to have the Samsung buttons available for use instead of the Google nexus menu. Correct me if I did anything wrong throughout the installation but I believe I've tried most of the options that were available to me but I can't seem to find what I've done wrong.
Thanks in advance for the help and sick rom Buddy, keep doing the gr8 work!
edit; I'm running the Apex launcher
I keep getting a notification to update KANGAKAT to lollipop, how can I get rid of it? Thanks

My S4 is flashed to Boost Mobile. Whenever I install a custom ROM I get no 3G or 3G appears for no more than 2 seconds then its 1X. I nandroid backuped to stock and same problem so then I installed a Stock Deodexed NG2 Refitted ROM and right when this ROM boots Boost ID pops up it installs apps and puts it to my boost homescreen setting and my 3G and everything works fine. APN settings are the same when I switch ROMs so I have no idea what the problem is. I want to install a custom ROM like NegaLite but I am stuck at this point.

Right now I am on NG2 4.4.2 Stock deodexed NG2 Refitted ROM. This is the only ROM that my 3G works. My 3G worked on stocked rooted then I went to Negalite didn't work. So I nandroid to my stock rooted and 3G didn't work anymore so I tried this ROM i currently am on and it works.
My apn settings are all Sprint APNs and everything works fine and when I flash a ROM my APns are still the same but 3g is ****. I tried using APN backup and restore on this ROM it lets me disable ICS Check but when I install a different ROM that doesn't work so I can't use it. I even tried moving it to the system.

Are you sure it's true 3g on the refitted ROM. Sometimes it shows 3g but its really 1x. You can check under about phone status. 3g normally works for me as soon as I flash..no need to add apns. I only have to edit mmsc in APN settings to get MMS.
That's what usually happens to me. I installed Sac's ROM and everything works and I actually really like this ROM so I'm going to stay on here. I'm still trying to figure out how to remove this data stat notifiation or something on the top right and also how would I remove a NO SIM notification since I'm on Boost now I don't need a SIM
