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.

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.

I believe that's the dial code.

I have tried to find this all over the xda forums and I'm sorry if I have over looked it somewhere but here goes...
I'm working on trying to root my new Galaxy S4 SGM-M919 from T-Mobile. I have managed to use Odin and flashed the stock firmware so I can confirm Odin works with my make/model but I have not found a tutorial on the xda forums that tells n00bs what to do.
Currently I have been using the following threads to try to get it rooted...

On the ladder one I got my stock firmware to flash so that's a step in the right direction, but I can't seem to find any type of "insecure kernel" used in the "quick root" section.
Could someone point me in the right direction please?

Hey Malybru,
Know any Roms for the M919 that will let me keep Wifi Calling? Tried the 4.3 Google Play Rom but it doesn't have it. Back on stock with root until I find a solution.

Hey man, first download odin 1.85, go to this thread http://forum.xda-developers.com/showthread.php?t=2294005 is located in this same site. Follow instruction but basically create a backup of all you applications and phone contacts!!! after that power off phone then when its off hold down volume down button and home button then while holding those button press the power button and when it vibrates let go of power while still holding volume down and home (you will get to the download screen. When you see the screen start odin using administration rights then press the volume up on phone. Under the PDA look for the suto jfl file and start it up and it will root for you. Once the phone starts open the store and update SuperSu (I suggest buying the professional to show support) after update open it and let it update the binary files. Your are now rooted my friend, I suggest get titanium backup, adaway, F-Droid (google it F-Droid apk download) install that and look for AdAway, get ROM Manager to flash and backup your current rom, also get triangle away to reset the flash but can only be used on stock rom and being rooted. If this helps please give that thumbs up. Good luck

I use Infamous ROMs, they are the best in my opinion, lets you fully customize the phones look and keeps the stock applications but without the bloat stuff and very reliable and fast oh and it comes with a few other apps for over clocking. Buy their 3Minit Settings from the store to show support and this will also let you customize the look and feel of the phone and it can be used with all of their custom ROMs.
I'm on 4.3 OFW Infamous v10 Galaxy S4 (this can be install on many different versions phones, just follow the instructions while installing.
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....
SOMEBODY TAKE OUT MY MISERY!!!!!! :highfive:

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!)

Below is a link to an app that will unlock the hotspot with the stock ROM - I haven't been able to find a custom ROM or recovery for the gs5 sport (sm-860p) mostly because I don't think many devs have one yet - i've been talking to the dev of this app and they are really helpful!

ANYONE KNOW OF ANYTHING ELSE I CAN DO WITH MY SM-860P??? got the hotspot, looking to mod the toggles and quick settings, kernels, roms, ANYTHING PLEASE!
A couple days ago I noticed that my S4 wouldn't turn on WiFi. I would "flip the switch" in the WiFi settings and it would stay in the on position but grayed out, then after about ten seconds it would switch back to off. At the time my phone was rooted but wasn't not on a custom rom, but had simple things done, like xposed installed and some modules. I think the problem is that I tried using the WiFi tether TreVe mod and it didn't work while I was traveling. When I got to a place with WiFi it didn't work and that was when I noticed the problem. Since then I have tried everything from updating the baseband, flashing Cyanogen mod, to even unrooting and re-rooting the phone but all with no success to getting my WiFi to work. This is my first post to any forum so much help would be appreciated! Thanks!

You can get the latest from this forum or sammobile.com (Sammobile is a little slow downloading) and flash it using Odin. There are several tutorials as well. Just search this forum and/or Google and you should easily find it.
