[Q] i9505 - No reception, black screenfreeze, no sound

Hey all, i got this serious problem.
I've flashed most of the cutom roms right after buying the phone but at some moment i decided i wanted to return to stock again as the phone was behaving weird. I did, was a TNL 4.3 dutch stock rom. After some months i began to encounter no reception problems, it first started once a week for a whole day then it was 3 days problems 1 day reception. I then decided to flash a new 4.4 custom rom to see if it solves the issue but it didnt, i tried to flash a 4.3 rom and then the no sound/black screen/ phone dialer freezes started to occur. I flashed the 4.4 UFNA1 modem, it still persists, i flashed the nightly 4.4 rom and reflashed the UFNA1 modem twice (which was done correctly) and i still have no sound etc... What am i doing wrong here? I feel terrible as i also have no warranty left ofcourse.. Btw. I tried flashing to several stock roms by ODIN which coused the program to freeze and the phone went into a bootloop, which could be fixed by just flashing a custom recovery, and after that ofcourse a custom rom.. Very strange! Someone has an idea??
thanks

Can anyone help me?

It actually worked. Thanks!
There's only this thing, which i can't test atm, but the sim reception problem i talked about, will that be fixed too?? That's the biggest issue and iv've read a lot about it on the net, nobody could seem to fix it. Lots of em said it was an internal error which got fixed by their warranty (they say they got new phones, up till 3 times..) They tried replacing sim/sd bay which didn't solve a thing. Anyone else experiencing this problem and got it fixed??
thanks

Hey, didn't i just flash a modem? Which fixed the sound/freeze bug etc? What if i reflash another (4.3) one and get that old problem again? (im on 4.4.2) I tried selected gsm/lte/wcdma settings manually, the phone was totally dead. My little brother who owns exactly the same phone and carrier (tmobile) have had 0 problems with his phone, he never touched it though and only recently upgraded to 4.3 by KIES. I tried switching out sim cards and my card worked on his phone, but his card didn't work on mine.

We already fixed the Sound problem and Im sure that signal Dropping issue can fix it easy just flashing a different modem/ or setup the right APN.

Hey all, the XXUFNA5 modem helped out great, untill today where i'm getting no reception at all again.. i'm on the Google Edition 4.4.2 rom prerooted for about 3 days. My speeds and reception were great before this and had no sound/freezing issues aswell. Anybody know what to do?? If i look in the REF modem topic, it's not showing any new modems? Am i missing something? Thanks in advance!!!
Edit* it seems in Holland they are using this modem -> I9505XXUFNC4
Cant find it anywhere though, any tips??
Thanks

Come on guys, not one reply? This is urgent, need some help!

I'm having this reception problem ever since I got this phone from my friend overseas I tried everything flash stock ROM ,change modems, flash custom roms and still no signal I tried different Sim cards also, I'm guessing maybe something is wrong with the main board? So I just gave up and started using it as a media phone alone

I9505 - No sound, no calls, no video

Hi,
I've had som rough weeks with my GS4 I9505. Hopefully some of you can help me.
I'm running CM11 nightlies, which was doing pretty great, until 3 weeks ago, where the media sound disappeared.
Well actually, I found out that the media sound WAS playing, but it was SUPER low. I had to put the volume at max and lay my ear directly on the speaker to hear it just a bit.
I read that a couple of others had the same problem, or at least I thought so, but now I tend more to think that my problem is/was hardware related.
Anyway, I tried flashing a lot of different firmwares, to match the bootloader and so on.
I am currently on:
Bootloader: I9505XXUFNB9
Baseband: I9505XXUFNB9
PDA/CSC: BLANK
The latest stock Samsung firmware I flashed, was: I9505XXUFNB9_I9505NEEFNB2_NEE
I am from Denmark and my phone is unbranded.
When I did that, the phone got VERY slow and wifi didn't work. Then I flashed CM11 again and wifi worked.
But now I am totally unable to make calls, it just freezes up and finally makes the call, but the call-speaker, media-speaker and microphone doesn't work.
When I try playing video (and some games) the specific app freezes and crashes too.
If I at least could get back to where my call-speaker/microphone worked and I had super-low audio I'd be ever so happy, 'cause then I can go and get a new media-speaker.
I hope someone can help me, otherwise I'll have to trash this phone, which I've been pretty happy to use for a while now.
Any pointers will do!
Thank you in advance.

Do you have an all working backup?

That's what I'm running on now - A backup before all this..
But, as the bootloader and modem has changed, it still isn't working, sadly.

Hi mate , hi DeepankarS
Seem like two different problems here.....
the low volume may be a hardware problem , the speaker gone bad , if you can hear fine with your earphones i would say is a speaker problem...really easy to replace btw.
the other problems showed up after flashing so i asume they come from bad flashing........backup , also efs folder , do a factory reset and flash stock again.......what recovery you have ? the important thing is to leave the phone clean before you flash with Odin

Hi MAX 404
Yea, they started when flashing new bootloader and modem.
I'll try that in the morning (again) - It's quite late here.
I'm on Philz at the moment.
So, the phone should be totally clean before flashing with Odin? I don't think I did that last time actually
What firmware should I flash? The same as last time?

Download the latest 4.4.2 for your phone and then in odin, uncheck auto reboot.
After flashing keep the phone off for 30seconds plus and then turn it on

Well actually I don't know which one is the latest.
I'm from Denmark, which isn't listed on sammobile.com - Anyway, the last firmware I flashed was I9505XXUFNB9_I9505NEEFNB2_NEE
Should this be fine to try again (again...) or is there a new one for my phone?

Dowbload any october/september build without carrier locking.
AFAIK, there was this UK one of October. You can try that
Also there is an Ireland one without carrier locking
AND IF YOU ARE ROOTED AS OF NOW, BACKUP EFS BEFORE FLASHING.
Use a good rated efs backup app from the playstore.

Hi ,
you have two options , factory reset and clean to install a new rom , try them both
Also would not hurt to mounts and storage menu/ format data and /datamedia ( /sdcard) that is your internal SDcard so is really clean....but after that you need to have a custom rom in the externalSD or go to download mode and flash with odin ....
Same rom as before should be fine....or download it again just to make sure is ok
BAckup first!! efs folder also.

Should I try flashing this?

The only thing I'm worried about is this: CSC: I9505TSIGNG1, as it looks kinda branded to me.

Then your hardware is dead. You already had low sound.
Get a speaker replacement and google this
Galaxy s4 teardown ifixit.com amd follow the steps to fix your speaker. Hardly takes 10 minutes.
Edit : Wait sound as in no audio in all the speakers?

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

When I dial that code, the phone does nothing...does the fact that I cannot turn on my mobile data stop me from dialing this code? Also, does the fact that I'm on cm12 and not on touchwiz stop me from using this?
& I have no password on my phone and there was no ro.securestorage.support ... I found this "ro.wifi.channels=" if that helps?

The code should work maybe is because CM , well last option would be to flash a stock rom and see how it goes........how you know power save is off?
BTW in your wifi setting there is no proxy ? did you try to delete settings and do a new one?

Damn really didn't want it to get to this, will I lose root access too?
Isn't power save automatically off in the settings? It gives you the option to use it in low battery
& I don't know how to check if there is or isn't proxy. What do you mean by deleting settings?

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.

Hi ,
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.

Simple inquiry about WiFi when screen's off

Hi there, fellow enthusiasts!
My phone doesn't connect to WiFi when the screen is off. As soon as I turn it on, it's good to go; connects within 2 seconds or so which is great. I'm just wondering why it doesn't connect to WiFi when the screen is off. I've tried every option possible and for well over a year now it just doesn't go thru with screen off automatically. I've switched ROMs, done stock, you name it.
It's annoying to have to take the phone out of my pocket, wake it up, and then check my notifications; it should be doing this automatically. I know it does this with data fine but I don't use my phone like that, I'm a WiFi only kinda guy.
Help me troubleshoot. Any help would be of so much help. Thanks!

Modem: MDM9615M
Bootloader: L720VPUAMF9
ROM: CyanogenMod 12.1-20151012 jfltespr
From what I can gather the WiFi needs to poll more when the screen is off. Once in a blue it'll connect with screen off (may take up to 2 hours) to a known SSID. I'm not concerned about battery life with more polling, honestly. It'd be way more convenient to not have to turn my phone on to connect to an SSID.
I believe it used to work on 4.4 but I can't be sure. That thread I linked to said the behavior started on 5.1 if that's helpful.

Ok
The issue you are having was a common issue, but no one has that issue anymore. If I remember correctly that issue happens when you are running an old modem on new firmware. The wifi disconnects when you turn the screen off.
You are using a 4.2.2. bootloader and a 4.2.2. modem with a Lollipop rom. Why haven't you upgraded to a Lollipop bootloader and modem?

haha I honestly don't know. Like I said, I only use my phone with WiFi (Hangouts and Optimum Online = no monthly bill.) I didn't think I needed to upgrade. Which modem do you recommend I upgrade to? I'll report back as soon as I upgrade.

I don't know which modem since this is the section for the i9505. It's a different model. You can also just flash the latest stock rom.
You have to check here, but at least you know what to look for.

Same result. Firmware upgraded to latest.
It's not that my WiFi turns off when the phone is asleep. It'll stay on whatever WiFi I'm connected to, but as soon as I am out of range from it, it obviously will disconnect BUT then it doesn't connect to any other WiFi in range unless I turn the screen on first. That thread I linked you to lists the same exact problem.
I appreciate the help.

Your modem didn't update. Try reflashing the firmware you just flashed. Only this time do it twice. So flash it, reboot phone, flash it again.

I was on L720VPUAMDC when I made this thread, then after Odin it's on L720VPUAMF9. That's the latest, no? What do you mean it didn't update? Anway, I'll try again twice.

L720VPUAMF9 = Jelly Bean 4.2.2
So not, it's still a very old modem.

Oh *slaps self* I see. I upgraded the modem to NG2. Still the same issue unfortunately. I really thought we had it this time. What else could it be?

*edit* Actually...IT WORKS! It connects to a known WiFi network when the screen is off in exactly 4 minutes. Much better than before where it was not at all or hours. You've been completely helpful, dude. Thank you. I just have one more question, is there anyway for it to poll faster with the screen off? As in, can I get it to connect to an open WiFi network under 4 minutes or instantly?

i9505 loses wifi connection again and again

Hey guys,
I'm using a i9505 as a media device at home. As opposed to all my other devices this phone loses its connection often every few minutes and also often doenst reconnect itsself. Its super annoying. I cant stream nothing or make a internet call.
Has anyone any idea? Flash a modem?
I'm on LOS 16.1

Flashing a modem won't hurt. You should be on the last one for your device anyway.

Does it really not matter whether I download the variant of my country (...HPK2) or the latest without my country code (... HQK1)?

Your carrier stopping at HPK2 simply means they didn't bother putting any work into what to them is a minor update. HQK1 will work on your device without a problem.

Hey again, I flashed the latest STOCK I could find on my i9505. But with STOCK i even cant enable wifi. I already did a factory resst but it doenst help.

If you unpack the ROM package I believe you will find a .bin file for the wifi you can flash in Odin.
