S4 i9505 - my LTE option disappeared!? - Galaxy S 4 Q&A, Help & Troubleshooting

I was having some issues with SU on my UK Galaxy S4 (EE network, i9505) so I did a reinstall. Wiped cache, reinstalled Omega Rom
Everything appeared to be ok. I incidentally switched in the menu from LTE to GSM/WCMDMA. When I went back later to re-enable LTE, the option had completely disappeared from the menu!
I have since done a full restore to basic, standard ROM, and reinstalled everything. Still no LTE! What happened? I have my EFS folder backed up, should I restore this? How do I do that?

Help!!

It's a few installations ago now, but I think it was a different kernel that fixed it. Either Adam kernel or Faux. I have since moved ROMs to FoxHound and am much happier. Less bloatware, better battery efficiency, fewer problems with WiFi and LTE. Good luck!

No don't do it. Lots of stuff won't work.

Any idea where I could find i337M odin files?
The reason im asking all this is this phone lags a LOT! and Gallery app is almost unusable from the lag. Any ideas? Thanks

First use Motochopper to root so you can use Titanium Backup to freeze the bloat (http://forum.xda-developers.com/showthread.php?t=2252248 this one will work).
Then you can install Goomananger so you can install TWRP (menu=>install open recovery): https://play.google.com/store/apps/details?id=com.s0up.goomanager
Finally, if you're feeling brave, you can do a backup of your phone first then try installing CyanogenMod: http://get.cm/?device=jfltecan
The Canadian model is jfltecan. Remember to install GAPPS (http://goo.im/gapps/gapps-jb-20130301-signed.zip)
I TAKE NO RESPONSIBILITY IF YOU BRICK YOUR PHONE.

unfortunately there is no firmware for (M) variant on the net. There is AT&T (USA) firmware, but for I337,
any way try to wipe cache via recovery.

Whats strange about it is the fact that right away, it had lag. I will try wiping the cache and will let you know.
I had an error when I tried wiping the cache.
Should I install a custom recovery as suggested earlier?

Someone else tried already. Apparently it will run. but without a Canadian modem to flash, there will be no network signal or wifi working.
When we have a modem to flash we should be OK.

Its SLIGHTLY better after clearing the cache via TWRP, but still lots of lag. Dont get it, from such a fast phone, there shouldnt be ANY lag! My Nexus 4 was SOO much smoother and faster (yet clearly not in benchmarks)

I too have an SGH-i337M (TELUS). Did you do the official update to build I337MVLUAMDJ? I had originally bought my phone on the unfinished I337MVLUAMDC and when I did the update a lot of the lag went away. However, I still had to freeze a lot of unwanted apps though settings > app manager, however I did come across a list of apps that were safe to remove/disable on the S3 (Some, not all are also found on the S4). You can see the list HERE.
Hopefully we'll see a list like this for the S4 soon.
[EDIT]
Also to note, I also came from a Nexus 4 and can definitely feel the difference as well, but the Nexus also didn't have bloatware running.

Mine came with the official build I337MVLUAMDJ and it was laggy as hell!
After rooting and removing lots of bloatware, it was still slow.
What cured my lag, was downloading the stock Firmware from Kies (and saving the file from temp folder, instead of using kies for the restore) and flashed it with odin. After restoring my backup from MyBackup Pro, its fast!
Why should we need to do all this work for a brand new phone. Good job Samsumg lol

Oh cool, I guess that works too lol. I managed to fix a majority of my lag after running a recovery script called "PalaTool" which was originally released for the Galaxy S III. The tool was designed to remove bloatware and allowed you to install optional UI changes and apps that could optimize things like Fast Dormancy, etc. Running the tool unfortunately doesn't remove the bloat, but it did with the Seeder Entropy Pool.

RIL Issue

So I had my nexus 4 working this morning and suddenly my internet died, I couldn't connect to internet but my SMS was working. When I came home i connected to WIFI and tried to flash some kinda weird RIL, when I did everything died, sms, calling, internet. Im running cyanogenmod 11, does anyone have any good way to fix this and flash some custom RIL with badass functionality ?
EDIT: Fixed, but internet still wont work, when i connect to wifi in status bar it says T MOBILE when i disconnect from wifi and go to 4g it says, NO INTERNET CONNECTION.
Maybe flashing a factory image solves your problem. (if not, it's most likely a hw failure)

I'm not really in a mood for loosing all my data again and reinstalling rom completely..
I suggested it because this way you can rule software failure out. (Do a nandroid backup, so you can restore all your data if you want to)

HELP! WiFi Issues

Sorry I'm a noon, don't do all those font sizes and colours and pictures aha but basically... I've been on CyanogenMod for about a year now and have never had WiFi issues. Been using cm12 nightlies for most of this year with no problem however, after updating my nightly the past two days I've been experiencing WiFi Drops happening every min and a half or so. So annoying. I've used Wifix apps etc, no luck. I've reverted to old night lies I used to run without any problems however the problem stays. I've consider flashing back to TouchWiz to see if that helps it but I really don't want to
Can someone please help me. My phone is on contract and my bill is overdue so I won't have mobile data until it's cleared (around June) so if I don't have WiFi, I'm screwed.

Have you tried flashing a new modem? This generally fixes wifi (and sound issues if there are any)
I barely know what a modem is haha but if that's the case, I'll try today.
Here you have a list of modems. Read the topic as it also has some info and the flashing guide.
You need to go to sammobile firmware checker and input your phone model, country and carrier. Then it will show you the correct firmware for your country and carrier. Based on that, download the modem. Make sure you get the latest modem. If you can't find the latest modem on the linked thread, there was another thread with all the latest modems, but I can't seem to find it anymore.

I'm on 5.02 CM12, I downloaded the latest modem for my GT-I9505 which matched the firmware code for a 4.4.2 S4 however still no luck ffs. This is really annoying, i don't know how my WiFi could jist shut off on me like that :/. Looks like I'm going to have to buy myself a new phone then. Can't use my mobile data for a couple months as my carrier has blocked me until I pay off my bill and now with my wifi disconnecting every 2 mins, I basically cannot use the internet. So frustrated.
I've flashed new nightlies, changed baseband versions, factory reset my phone and still no luck. What makes things worse is i cannot see any other threads with people in my postition so help is so minimal :/. Annoyed is an understatement.

Go back to stock firmware if you haven't updated the bootloader.
If it works fine on stock, then re-root your phone and try again with CM12.

Check and see i if power save is on , if so switch it off
Dial *#0011#
This will take you into the Service Mode
Press the left bottom key new menu will show
Select Wifi... Once in the Wifi settings , turn it off...
Do you have to refresh the password? just in case check this
Go to /system
Open the built.prop
search for ro.securestorage.support
If it says true , change to false
Save and reboot
Also if you are skill check the antenna cable inside the phone..maybe is just loose

If you updated bootloader then you can't go back to kitkat roms. Only the 5.0 lollipop roms. But Samsung hasn't released the official update in all countries.
If it still doesn't work, even with official firmware, then it might be hardware related. Maybe even your wifi router.

yes can still flash an stock rom....but why you do not try first
flash a different modem
flash a different kernel
If every thing else fails flash a stock rom, what model S4 do you have I9505?

Hi, i'm going to flash lollipop touchwiz onto my phone using this http://www.ibtimes.co.uk/android-5-...-s4-lte-how-manually-install-via-odin-1492230.
Anything i should know/do before doing this?
Did you flash an alternate kernel?
Wifi issues are often kernel related. Not always...but often.

No mobile data

Hi,
Since this morning my mobile data is not working anymore. The toggle works but no mobile data. I already flashed the rom again with a full wipe. Nothing. Also tried recovering from an old backup... No luck. Re-entered my APN, rebooted my phone... Still no luck. I think I'll have to flash a stock rom? Or any other suggestions?
Thanks
It maybe a hardware problem. Can you access the engineering menu to test if data is working ?
