[Q] [NOT FIXED- GS4 Lots of issues with radio signal and calls!!!! PLEASE HELP ME!

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!!!

You're having that issue on either GoldenEye or MDOB or factory?

Man, I decided to return to full stock rom...LTE in perfect shape now...dont know what happened...i flashed with odin the exact version indicated in forums for making only the root without the custom rom or recovery...even that soft rooting is making my modem going crazy...i prefer stay this way until someone releases a decent full version for a GS4 SGH-I337m thanks guys

Did you try one of iB4STiD's ROMs? They work perfectly. CM is just way to full of bugs.

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!)

NO SMS

Hi guys I've had a on going issue that I though I would give another try at fixing.
I have unlocked my phone and am using a UK Vodafone sim and everything works fine when I use the stock rom
If I use an AOSP (I currently have slimbean build 2 installed) I am able to receive SMS but not send. I get the error "sending failed"
I have enable GSM using Xshortcut
I used HiAPN to get the APN
I'm using the MF9 baseband after downgrading then re-updating to get the unlock.
I have 3G internet.
Would it be possible to export the settings used in stock for SMS and port them to the AOSP rom?
I have tried using chopsms to fix the problem but that didnt work
I'm really out of ideas
All I need is to be able to send an SMS on Vodafone UK
Sorry for also posting this in the apps section as well. I cant see how I can delete it
fingers crossed
Thanks
Jamie

I ran into a similar problem when I used an aokp rom, check out my thread on the domestic unlock and look for nicotheandroidguy 's suggestions for aosp/aokp. I ended up just running sacs rom instead of slimbean
Also are you setting it back to gsm/umts AFTER you install slimbean? I found whenever I did a wipe and install I had to tinker again, reset to gsm, reinstall hiapn etc.

I'm testing out sacs now. Seems interesting even though its based on stock. I do all the tinkering after in install slimbean but no joy

T-Mobile LTE

I am interested in enabling T-Mobile LTE on my N4. Does it work smoothly like any other LTE enabled phone? In my research, I've found that there are two different zip files to flash. Which one has worked best for people? It appears that enabling LTE is a simple flash of the zip file. Am I correct? Thanks.

This has been covered thousands of times. But before this thread gets deleted, let me help you out. LTE on tmobile or att works flawlessly.

just flash and forget it. it should work! good luck

Do I need to update the radios after every software update or can I just flash once and forget it?

Since this will get deleted anyways, I will ask the stupid question I have. Bone stock 4.4.2 soon to be rooted with TWRP. Can I flash with a stock ROM and still make a wifi hotspot? I see something about needing init.d support or something like that.

my suggestions?
flash a stock ROM, and do a clean up (factory reset & clear cache) from stock recovery. This is the simple way.
my guess (if I'm wrong, correct me), you come back from CM/AOSP to TW, and it start to be like this.

Well im not sure if I had rooted it properly but I did all that I downloaded the stock hk rom to try see if thag will get it from booting in recover I know thats the easy fix. My big issue are all the other problems I had before I even tried to root the phone

stock HK firmware ?
Is your device is N9005 HK/Taiwan version ?
if not, you can't just use the HK/Taiwan firmware onto your N9005.

Its the sm-n9005 the international model

if yours is the international model of 32GB N9005, it is strongly suggested not to flash HK/Taiwan firmware.
This 2 firmware is basically only for HK/TW N9005, which is earlier was came in 16GB. Means the partition is different from the 32GB.
after that, they come up with 32GB, but... I might be wrong (correct me if I do), I read somewhere the partitioning also different.
So, Why don't u flash other international firmware ?
Have you tried other than HK/Taiwan firmware ?

I believe so as well. Regardless either 16 or 32gb HK fw doesn't play well with other regions n9005

If you haven't flash stock rom then just flash it first to see if the issue persists. Factory reset and wipe cache from stock recovery after done odin flashing.
If issues persist, root you phone again, install custom recovery sych as TWRP, use DrKetan's imei backup tool here
http://forum.xda-developers.com/showthread.php?t=2698639,
make a nandroid backup if your current rom, wipe system/data/cache(don't wipe internal or external storage if you save your nandroid backup and imei backup in any of them else you will lost it. You will never know when they would be handy if you lost your imei in any way). Then flash again stock with odin.
My friend's note3 has terrible lag after upgrade to KitKat. It took a few minutes after reboot just to get unlocked so I helped him to reflash using odin but after 3 different firmwares flashed still not get resolved. I did the same. No more issue after that.

[Q] Samsung S4 i9500, freezes and reboots after a while of use

hi, a friend of mine, here in El Salvador, had this s4 i9500, but for some reason an employee from TIGO company offered him to flash it with kitkat, the phone has no use, we downgraded the thing, no go, with three different version, Guatemala, Panama and Colombia, no go!!!!, if you use WIFI or 3G or simply opened an app. freezes and reboot, even we tried flashing it with cyanogenmod cm11, i dont know what else to do, the thing is useless, somebody told me that "KNOW" was related with this, because the previous JB stock rom had root and then tried with KITKAT stock rom with no root, i dont know about that, please help us
any help will be much appreciated
best regards

Did you flash again with a JB custom ROM? It might work, then wipe data/clear cache partition

I think you might have a problem with the cpu...you bought the phone on second hand? Maybe someone forced it in overclocking mode. I recommend you to send the phone to an authorized service, but if you say you tryed everything, the motherboard is the problem..

I agree, but samsung would say that the warranty is voided, other friend of mine thinks that this is related some knox partition, there has to be a solution for this
