[Q] Android 4.3 + Radio bug! - Galaxy S 4 Q&A, Help & Troubleshooting

Hi, I upgraded my phone to 4.3, and ended up with a buggy phone. Firstly i wasnt allowed to turn on wifi, or update my phone.. or install KNOX. Also, my radio kept rebooting, especially after i've turned the screen back on, after having it off..
Soo, i rooted, flashed Echoerom and the wifi-problem dissapeared, but the radio problem is still there.
I heard Nexus people had luck on flashing 4.2.2 radio on their device, but i dont know if it will work with mine?
I9505, Nordic edition. I9505XXUEMJ7_I9505OXXEMJ8_NEE is in the bottom on my phone.
Not sure what kind of Radio I should flash, or where I can find it
Anyone?

Okay, i found out: I had to change my preferred dataconnection away from LTE/HDSPA etc and just force GSM.
Settings->Connections->More networks->Mobile networks->Network mode-> GSM ONLY
Hope this helps anyone else =)

No data connection after rooting to custom rom (Darky's v5.6)

I'm new to flashing custom roms and what not. I used odin and flashed everything to the point, csc, modem,pda,pit the rom works awesome but i cannot for the life of me connect to the internet. the 3g icon or h icon wont' show up. in the status it says my network type is gprs and i'm roaming and my mobile network state is disconnected.
I'm with fido, the phone is unlocked i have never had trouble with data or anything until i flashed to a custom rom.
Anyone have the same problem or suggest how to fix?
Data Conn. Issue
Hey mate,
Have you gone into 'Settings', 'Wireless and Networks', 'Mobile Networks' and then 'APN settings' and entered your appropriate settings?
That should fix it if you define the correct access point.
Alex
hey man, yeah i did all that stuff, went in there, found my carrier, put in all the apn settings i can find and still nothing. when i put data roaming on then i get data and the edge icon comes up.
Hey dude,
That sounds strange, flashing custom (or even release) roms is never a guarantee especially with weaknesses in the way that ODIN communicates with your phone, What I would do is Re-Flash your stock rom through ODIN then use the "quick" install method from Darkyy.
I am running 5.6 like you, and I had issues doing it through odin (I kept getting random FC's), additionally, the rom; if installed from CWM will keep your apns and apps e.t.c. along with many settings and configs from the base rom you're using before the flash.
That is the best advice I can give you.
Alex
My config is a follows:
I9000 International
16gb SDHC
500HZ Hardcore Kernel
Darkyy 5.6
Whats the process for reverting back to stock 2.1 eclair rom?
Did you keep a record of your firmware version before reflashing?
If not, you may have to ask someone on here what your base firmware was.
Are you familiar with using ODIN? (The software used for reflashing)
Alex
I am having same issue to...I used 5.4 from Darky and it works well...same with DocRom 4.0 works and the next 5.1/6.0 don't work.
Both Darkys and DocRom are based some JPX....which seem to be root cause..
I've have the same problem. Tried eveything but still didn't work. So went to Samsung Service Centre to have my SGS firmware refresh. I notice after the refreshed same issue of data com missing. Told them and they when into the SGS to select the telco operator setting selection. Now data com. working well. Anyone know the SGS handset setting code? I want to reload to Darky's v5.6 again.
hi folks
i have the same problem... my provider is a virtual provider in the network of our biggest provider here in austria. i was using doc's rom based on xwjpa firmeware and everything worked fine without enabled roaming options.
since doc's rom is based on the newer releases (xxjpx, xxjpy) i' only able to use data connection if i turn on roaming. it also shows me that i'm in a roaming network. i guess the cause are the xx firmwares. xw and xx are european firmwares but i do not know the differences between them. maybe someone has more information about the differences? currently i'm using xwjpa firmware because i don't want to use my phone with enabled roaming options.
hey um i'm having the same problem and thought replying here would be better than starting a new thread.
well i installed the rom without having any idea of what i was doing *stupid idea* so i didn't take note of my original firmware.
i didn't use odin to install the rom just clockwork recovery and the rom and everything installed fine except my data network. i can get signal, call, receive the only problem is i get no data transfer. any help much appreciated. if anything can someone help me step by step to reboot my phone to original?
just for future travellers
Sadly this isn't my own gem, but yeah. hold the power button down, wait for the shutdown menu, above the airplane mode there is a data network button, and it'll most likely say "de-activated" if nothing else has worked. Its ok to feel like a chump, I did after rehashing the hell out of this phone for a few days ( the wifes phone, my phone does exactly what its told. )
Anyway, yeah, this will probably be the reason for the lack of the icon "G", "3G" or "H" where it should be.

No sound on phone anymore - Solved

so I spent yesterday trying to get my bell Galaxy s4 unlocked so I can use it on rogers
when I got the phone I updated to 4.3 right away not knowing the issues it would give me
after trying long and various roms I decided to flash stock 4.2.2 thru odin
my phone went from 4.3 on i337vlluemk6 baseband to 4.2.2 on i337mvluamdj baseband
I was then left with a new issue....... I now couldn't enable wifi
so I flashed another rom and wifi was able to be enabled no problem(did not change baseband)
to my surprise I was able to unlock the phone successfully now using region lock away.
"VICTORY IS MINE!" I proclaimed
until I noticed something................I now have no sound coming out of my phone. I tried another rom and still no sound.....so I flashed stock thru odin once again. Again the wifi doesn't work and there's still no sound
anyone know what might cause this or how I can fix it? Phone isn't of much use to me if I can't hear it lo
Edit: thru scouring google I was finally able to find a solution on here. Apparently I just had to reflash stock 4.3 and it now works
another thing
even though the phone is unlocked I 'm not able to dial out on it
doing so caused the phone to lock up
this happens in stock as well as 2 roms I tried
the data connection works just fine and I'm able to browse the web with my LTE
I dunno if this helps anyone but if I go in to service mode I can't even select audio as an option.
It's there (number 5) but if I choose it it does nothing
Same issue
I have the exact same issue. I was trying to get to Google Play Edition which I have done many time before, but this time the baseband version changed. Now I also have no sound, so wifi and my phone is locking up when I make or receive calls. HEEELLLPPP!!!!

i9505 Problem

Hi Again Guys,
My phone recently wasn't getting any signal when i flashed to the ROM 4.4.2. So people said to flash back to the stock rom, i have now done that and the WiFi stopped working. I can't even download a ROM manager to try and load another ROM.
I think i've really messed up my phone. I want to wipe everything completely and start from new, then re try flashing to the latest ROM 4.4.2 so i can get my WiFi and Mobile Data working again. I can't get calls without it having a black screen / no sound. My phone keeps turning off every so often.
I think i've missed matched wrong Modems and Baseband Versions?
What information do you need exactly from my phone to give you to try and help? Really need my phone working for work purposes. I will give a donation to a person that helps me fix it completely. (paypa)
Thanks guys.
I was reading ur latest posts and the solution is: HERE

[Q] Mobile network disconnects when the screen is off

Hello,
I've noticed something strange this past month. I was getting data disconnections and I could'nt figure out why. Each time I look at my phone, turning the screen on, mobile network (voice + data) is missing for a few seconds, and comes back.
Now I know that if I keep the screen on for a while (I tried more thant 1 hour), I don't loose the network, but if let the screen go to sleep I immediately loose the network (I don't receive whatsapp messages in background), and when I turn the screen on, it comes back.
Weirdly, when my phone could reach 4G, I had (almost) no disconnection. It only happens in a 3G, edge, or nodata zone.
I changed my carrier (I just moved from europe to New Zealand), and it doen't change the problem.
I'm using CM11-Nightly (sept) on a I9505. I tried installing an old nightly(from july), and it was really full of error messages, so I switched back to a recent nightly, but in the meantime I had no disconnection.
Thank you for your help

I don't know exactly where this option is, but it's for battery saving. You can choose that somewhere in your settings I think
I think that's true for Wi-Fi, but I never found it for network.
And now it seems that network won't come back if I don't go to airplane mode and back to normal mode.
I'm having the same problem, seems to mostly affect lollipop installs.
Did you find a solution?

No I didn't. It seems that somewhere in july 2014, CM11 included a new version of the modem. So every CM11 build after that and every CM12 build is affected (I don't know about other roms).
I read that it was the way the modem handled finding the best network method. With the previous modem (v5 ?) it tried to get LTE, 3G, etc... but now it fails when it fails to get the prefered network.
4 solutions:
- flash the modem (didn't try it, don't know how)
- You're supposed to be able to choose you're prefered network in the options and choose 2G/edge. Didn't work for me but I'm interested in your feedback.
- get an old version of CM11
- live with it (my current option :'( )
There is maybe another solution, I'm not an expert, just a desperate user.
Hey again, I did fix it for myself.
The modem is the problem (I flashed my modem, and my bootloader just to be re-up-to-date).
If you want to get lollipop for yourself you should do it, its not too hard
Its listed as Qustion 14 on this here page: http://forum.xda-developers.com/showthread.php?t=2419762
I don't mind trying to give some pointers if you need help understanding how to do it, but I did this at 5am while sick so my memory of what I did is not 100%, never the less I would like to help if you need it.
Thank you for the advice (you came seeking for one, and ended up helping me ).
How did you choose which modem version to pick up ? the latest ? Do you have to do it after every CM upgrade ?
Edit:
I found the latest version from one of your links : http://forum.xda-developers.com/showthread.php?p=50965837#post50965837
Is the "Combined package - both modems in one flashable file." ok ?
And what does flashing the bootloader do ?
"What it does"... I am not 100%, I assume it initialize some part of the system, HW or kernel level, but I might be way off.
In any case I did use the dual modem pack to flash both "PHONE" and "PDA", another thread I asked in just replied to another user with the neccessity to flash the new bootloader aswell (dont know if the version numbers applies for you):
u must be using a 4.4.2 baseband and bootloader .. just a 4.4.2 baseband will not work .. once updated ur set

My question is on this page a bit down, and some replies a bit further down than that:
http://forum.xda-developers.com/showthread.php?t=2735248&page=116
Tip: I had to save the PIT to a file (did it twice to be sure) with heimdall before using odin to flash (couldn't get heimdall to work for that part), all because odin would not play nice inbetween loading the PIT from device and flashing, this might not be a problem for you at all so it's just an FYI.
I managed to flash the modem & the bootloader. So far, no disconnection, so I'm quite happy.
Cheers

HELP! No IMEI or BaseBand after turning radio on

Hello, this is my first thread so I apologize in advance if something is wrong.
I will let you know what I have done so far, and why I have done it.
I have a G930A Samsung Galaxy S7 (AT&T version), I already permanently unlocked the phone by code provided by AT&T, here is the thing the phone has the radio off , so even if I place a SIM card, the phone won't have any signal, once I restarted the phone and it worked out of the blue, then again after it ran out of battery the problem came back, then I went from AT&T ROM to G930U ROM through tutorial on this forum, then I rooted it (https://forum.xda-developers.com/galaxy-s7/how-to/root-sm-g930u-tinysu-t3667800) now that root is working just fine, I downloaded build.prop, then modified the option: ro.radio.noril from no to yes, and after I reboot, the radio will turn on, but when doing so, I have no longer any network option, it won't show IMEI or Baseband, not 00000 nor unknown, it just won't show, if I revert changes, IMEI and Baseband will show again, but again no radio so no network signal.
I am a complete white page when it comes to android knowledge, if anyone could help me out to figure out a way to turn the radio on, and keep IMEI and Baseband information, I would really really appreciate the help.
Thank you so much in advance to everyone.
Ohh similar situation
Hi there,
Even i suddenly got my radio off even tho phone was working like charm 5 mins before but i rebooted and signals went off and radio was off. Now stuck with a useless device which depends just on wifi. How did you root it
Happened the same, haven't figured out how to fix it

Sorry for the delayed answer, I am still stuck with no signal, just like you said, useless device that depends just on wifi, I haven't figured out what is causing the phone to not get any signal, IMEL/ESN is clean and phone is unlocked, no idea what's wrong.
If you have fixed it, please let me know about it.
By the way, I rooted the phone with this thread: https://forum.xda-developers.com/att-galaxy-s7/how-to/root-s7-att-g930a-g935a-t3410538, give it a try it was easier than I expected, and I gotta say I am pretty dumb with this stuff, good luck.
