Hello! I have problem with my phone. I was on Cyanogenmod, but then i wanted to flash that resurection rom or whatever its called. Booted it up, but there was very weak or no network. Then I decided to reflash stock rom. On the first time there was no signal too, but reflashed again and everything was ok. I remembered that Touchwiz is unusable and flashed again CM. On the first moment, signal was ok, but after while it started to lag. Yesterday flashed back the stock rom, and for that moment everything was ok. Waked up this morning, and what do i see?? Yes, there it`s again. Weeak or no signal. Emergency calls only.
I checked that my IMEI is not changed. Have reflashed modem with odin, sometimes thinked that it was working, but reception keeps bad. Is anyone having same issue? Maybe you can tell me how to fix this and help me?
Actual signal in my house and everywhere is good, but all problems started when I wiped all data and flashed resurection rom or whatever.
Did you check proper support for the rom? Some roms in development(like one of the versions of the CM for the a300fu don't have properly working wifi

Ok here is what is been happening so far..
I was on Kitkat 4.4.4 on a i9505 (can't remember the baseband info for that model - never had issues with it). I decided to update. So I downloaded a LP ROM and went ahead and backed up and then installed it. Everything seemed to be working fine except my mobile data connection. It would be stuck on 3G or H+ and when it hit the LTE (4G) it would have one bar. I never had this issue before. I was always on full LTE bars as the tower isn't far from my house.
I followed instructions n how to install new modem with LTE and how to update the bootloader accordingly. I tried more than 15 different modems with no luck.
When that failed, I flashed the stock LP ROM from SamMobile - same issue. So I decided to downgrade again to KitKat and flashed another ROM from SamMobile which is issued by Optus Australia and that failed too.
It's like there is a setting that isn't changing with flashing ROMs and stock ROMS. Basebands get updated and nothing.. I'm barely downloading at 600kbs where I was averaging minimum 1.5mb/s.
I don't know what else I've missed.. surely the stock KK ROM would've fixed the issue.. but nothing, as if I don't have LTE anymore.
You're help is much appreciated.
Over this issue =\ just want it gone.

I have flashed anything and everything to fix this issue with no luck.
previous to this day everything had been running smoothly, but now since i flashed the 39a bootstack to try out a new 5.1 rom on my vs980 i seem to have lost my LTE connection. how would i correctly repair this? i head flashing a stock rom would repair some sensors, would i leave the 12b bootstack on it, flash a stock build, then flash back to say, beanstalk? previously running liquidsmooth but they seem to have taken their lollipop builds off the server...
I have the same problem - flashed Cloudy ROM, kdz back to stock but now I don't have 4G. I'm about to just try a new SIM card and see if it went bad, because I saw LTE for one day a few weeks ago and this all happened back in January. I've reset APN's and did all of the tricks but no luck so far
Literally just got it to work a few minutes ago. As of this morning had NO service whatsoever, ended up flashing the rooted 39a lollipop stock I found here in the forums. I had to remove my sim card, boot the phone, then restart it with the sim card in place to get back to working order
So do you think it was a bad baseband or bootstack? Or just a faulty download from the start?
might be a baseband issue, but then again i havent really gotten a solid answer from anyone.
and just flashed to AoD rom tonight and lost LTE again. maybe it has something to do with aosp incompatibility? i know there have always been issues with cdma network of verizon, maybe it came back fresh with the lollipop update.
and i despise the stock roms... i would not be happy if thats the only way to fix this.

If you haven't try dialling *#*#4636#*#* and go to phone information and in the drop down menu select the proper mode for your carrier. Worked for me on VS980 using T-Mobile

Can you share the settings you use with Tmobile? I just flashed the 27A kdz and getting connectivity issues with Tmobile.
Hello All,
This is my first post here and also my first attempt at flashing a custom ROM so please bear with me if I break any community rules.
I own a Galaxy S4 GT-i9505, which I had rooted 3 years ago and had never bothered to upgrade. So I used to have the default Android 4 in it. I finally decided to go for a custom ROM and upgrade to Android 6. Friends recommended I try the Ressurection Remix version which I did. I downloaded and succesfully flashed Ressurection Remix v5.6.3-20160214-jfltexx.
All work fine except for two issues which I will describe below:
1. Signal
The device seems to have no signal at all in many locations, including my home. I moved the SIM to another device and the signal is strong, so it can't be sudden problems with my operator. With Ressurection Remix the signal indicator says that there is no Cellular Network connection, and if I try to call someone, it fails with the "Can't connect to Network" error.
What's funny is that if someone calls me, I actually can answer the call and speak without any problems.
What's also funny is that I just came back from a trip where I had the phone with this Rom installed. While roaming, this problem did not appear at all. I could both make phone calls and use the roaming data connection without any complications.
2. Device Lag
After a while the device gets laggier and laggier, to the point that it becomes unusable. This feels like a memory leak. There seems to be an old topic about a memory leak in the Galaxy S4 forum. Does the Ressurection Remix Rom not contain the fix for it already?
for signal issue, update first your bootloader and modem to the latest veraion for your device..
Yes, updating the modem and bootloader may fix the signal problems. But once the bootloader has been updated, downgrading will be a bit harder.
There also is a newer version of Resurrection Remix available, you might want to try that before anything else.
You could also try the fairly new rom VRToxin if Resurrection continues to rebel.
Thank you for your replies guys. How can I find what is my current booloader and modem version? And where can I find the latest ones for my device (S4 GTI9505) and a guide/tutorial of how to upgrade them?

Since you never updated to the official lollipop, you most probably have KitKat bootloader and modem.
Guide here
Thanks GDReaper. Updating the Modem and bootloader did fix the signal problem so my most major concern is solved. :good:

For the lags you might want to try the newest RR version. 5.6.4 has been released.
I was running cm12.1 for quite a while with no issues whatsoever. After flashing cm13 official rom my wifi and bluetooth stopped working. I didn't think much of it, and figured it would be fixed with a newer nightly sooner or later. After running the rom for about 3 months the issue wasn't resolved in the newer nightlies.
I have been trying to work out the problem this week. So far I have upgraded the modem and bootloader, reflashed back to cm13 with a full restore, flashed back to cm12.1 also, and the problem persists with every rom.
Any ideas as to how I can tackle this from here?

Are you sure that the CM version is for you model?
I believe so. I have the GT-i9505 international model, and am running AntaresOne's official CM13 for I9505...... here ( http://forum.xda-developers.com/galaxy-s4/i9505-orig-develop/rom-cyanogenmod-13-t3282242 ).
I took the phone to a service tech today, who confirmed it wasn't a hardware problem at all. He then flashed me back to cm13 official rom (luckily I already had a nand backup), and said I needed to revert to stock and reset my flash counter and start again from scratch...
So I spend all afternoon flashing back to stock lollipop firmware and trying to get TriangleAway to reset my flash counter, which it couldn't.
I also downloaded TowelRoot but found out that it doesn't support my device. Eventually I managed to reflash TWRP and recover my backup, so at least I'm back to where I was yesterday.
After all that, I think I'm quite happy just to live with the fact that bluetooth and wifi are not going to work and save myself anymore headaches, as I'm using the phone as my daily driver.
As the title says, mobile data stopped working on my S4. Everything was fine until it wasn't. I have tried flashing the ROM again (official Lineage), tried other ROMs too but with no success. I have network, can send and receive texts and calls, Wi-Fi works too, everything works besides mobile data. Also tried cleaning the SIM and the contacts.
Any ideas?

Same thing happens when the phone is running the latest stock Samsung ROM?

I haven't actually tried the stock one because I'm afraid I'll lose my root and recovery and stuff. And it's very strange because it stopped working all of a sudden. I'm yet to try my SIM on another phone though.
EDIT: Is this the latest stock Samsung ROM? https://mega.nz/#!O8QEGCqC!vu7Op5QTNEWd27FJLHs-nYd0G8V9QDSkQEZxMcYuCWU
If everything works with a stock ROM, then you'll know that it's a software issue which is easier to deal with.
