i537 no sound at all (calls, music, ringtones) - Galaxy S 4 Active Q&A, Help & Troubleshooting

Hi, I hope you guys can help me get this phone back to usable state. Recently I got a S4 Active i537 that was stuck on ATT logo, so I did a little research on how to restore the stock firmware to get it working again and came across with various threads; I finally downloaded the I537UCUBML2 stock rom and used Odin 3.07 to flash the files all worked fine except the BL_I537UCUBML2_2244695_REV06_user_low_ship_MULTI_CERT.tar but th phone booted anyways so I thinked that was the end of my problems. But after putting a sim the phone did not get any signal so I checked the about screen on settings and found that the IMEI and BaseBand were blank.
I did another search to fix that and finally could make the imei and baseband came again by flashing the Modem.bin 50,791kb file found in the GPS IMEI FIX THREAD but after getting signal I realized the phone was completely muted and calls were not working, at first I believed it was a hardware problem but now Im pretty sure that it must be some software issue because it wont even play music, ringtones. When trying to open a mp3 it shows a message saying Unsupported.
Back when it was stuck on ATT logo it was making the att boot sound so Im pretty sure that the problem its in the software itself. Please help me find the correct rom/firmware to get it working again.

Flash the NE3 firmware so you'll be on 4.4.2 and see if that fixes things. If not, report back.

Would you please share the link to that? I don't want to mess this phone even worse by downloading wrong files. Thank you

i think i broke my phone :( help needed

hi all
i thought i would attempt to flash my samsung s with the new beta froyo update.
i followed this guys tutorial.
( cant link to it sorry its the noobs guide with detailed instructions through kies and odin)
i used the odin approach
i managed to root the phone.
on reboot it asked for an unlock code (o2 uk) so i went on to try and follow the steps about unlocking it. which neither worked all the way through the steps.
on reboot it appears to have signal and in the about section it says i am onnected to the o2 network but when i try to make a call is says "data network not available with an ok button, which when pressed will return you to the ome screen.
any help would be greatly appreciated thanks
Almost the same problem,
installed 2.2 update successfully, the phone worked for like 3-4 days very well and after that today i discovered "Emergency calls only"
so the question now is did i bought phone which later was reported stolen? or somehow i broke it?
Anyone have any idea?
hmmm, I have the same problem! In the status menu, the number is shown, but the network, says "unknown"
Hi! I have this exact same problem except I was unlocking my phone using this tutorial:
http://forum.xda-developers.com/showthread.php?t=906255
But I didn't back up my Efs folder, now my phone is unlocked but when I put a sim card in it I have very little network and when I try to make a call I get " NO DATA NETWORK AVAILABLE".
I've tried everything but I don't know what to do!
I was thinking of two ways to fix it:
1. Reinstall froyo (not quite sure how using the samsung software as my laptop oesn't recognised the phone as a pone)
2. Downgrade to, get unlock code using market app and then upgrade to froyo again.
I know I messed up but now I really need to fix this.
Can someone PLEASE PLEASE help me out.

might need to change the modem in odin i think. just heard about it
did u try restarting the phone... just a wild guess...
I had the same issue before and was puzzled. Its actually a very simple solution:
1. Re-lock your phone, search through xda there is a code you have to enter
2. Unlock your phone
All done! Surprisingly easy
Try the Odin method in block 2 back to Eclair if ok then upgrade to Froyo .
http://forum.xda-developers.com/showthread.php?t=818556
However your non connection might be due to not flashing a firmware with your network settings in which case manual settings of APN .
If your IMEI has changed due to flashing and you did not back up your EFS folder then little hope but do a google / search of XDA as some have reported success .

Emergency calls only
I had a custom rom that was giving that to me too. I think it means that you can access a network different from your sim (because usually emerg calls can be made from any phone I think?).
I'd try and find a rom that is optimized for your carrier or at least a modem file from a stock rom that is for your carrier. You may also need to reselect the APN settings (or enter them for your carrier). Its under settings/wireless and network/Mobile networks/access point names (use the menu button to add an APN).
you could also try re downloading and flashing the rom to make sure that is the issue. Mine said it installed OK but never booted up, redownloaded and reflashed and then it was fine but the install screens looked identical.

Hi! Thank you so much for everyone's replies!
My IMEI isn't changed and someone helped me check my efs files and they are all ok. I'm going to try and reflash froyo through the samsung software to see if the network lock comes back and then try to unlock again. For this I'm going to unroot the phone and follow samsungs' instructions.
I'm afraid to relock the phone as there are reports that say it completely messes everything up!
But I'll keep you guys posted! Wish me luck!!!!
PS. Any other suggestions are more than welcome!
So, a quick update on my situation.
I uninstalled busybox and unrooted my phone using the oneclick root tool.
Did a factory format and, surprise surprise, my phone now works perfectly!
Apart from the fact that it doesn't connect to kies, but that's a whole another issue!
Tank you so much to all of you who answered my cry for help!

HTC Vivid Radio/Baseband issue

Hello,
I have searched multiple forums for hours today and have figured out what is going on with my HTC Vivid. (It has been upgraded to AT&T Official ICS.)
It was working fine up until yesterday where it was not receiving a signal from the mobile network and the signal icon has an X through it. The SIM card is properly inserted and another SIM card has been tried as well. Looking through other threads it seems like the Radio RIL files may be missing or corrupt. The IMEI number and *#06# code does not show an IMEI number either. The baseband version says unknown. I am not sure what happened as I have never loaded any other ROM on it.
I downloaded the Official RUU ICS upgrade ROM today and tried reflashing it, with no luck.
What is interesting (and the other person who had the radio problem) is that when I left the phone sit off overnight and then turned it on in the morning, the phone connected to the mobile network and I had a signal. When I restarted the phone, hours later, the phone lost connection to the mobile network and that is when I started digging and found the problem with the baseband version being unknown.
Is there anything anyone can suggest? Can I reflash the baseband files or copy them from someone somehow using ADB? It seems like there is where my problem lays. I've searched for ways on how to downgrade from ICS to the official GB stock rom, but it doesn't seem like it can be accomplished.
(I tried downloading the Holiday Cingular version of the GB stock rom but the update failed. I read about the ICS HBOOT version being different and not allowing it.)
Thank you in advance for helping and any suggestions.
Have you gotten a new sim card yet? That needs to be your first step. My captivate did the same thing and turned out the sim went bad

Yes I have tried a different sim card. I don't believe thats the issue though being that it worked with the same sim after I let the phone sit overnight. From reading about others experience, it doesn't seem that the sim is the issue but more the baseband version and imei information missing.

I had a similar problem and thought I solved it, but I later realised all my "solutions" didn't bring back the network but coincided with its reappearing cos no same "solution" worked more than once.
It's a very weird problem as the network shows up once in a while and when I'm using Mobile Network for Data, my phone hangs again and the IMEI, Network, baseband disappears on reboot...till further notice. I gave up trying and concluded it's either a bad modem (hardware) or something AT&T knows about!
You can get HBOOTS for both GB and ICS via Hasoons AIO kit
Flash the HBOOT, Flash the Image from Cingular GB RUU and I wish you luck!!!

I found the download link, but the website says they're updating their drives, so who knows how much longer that will take.
Also, are you saying I should just use the tools within the kit to flash the HBOOT back to the previous version compatible with GB and then flash the RUU GB image after? Can I do that with the phone connected via USB or does it have to be flashed from the SD card? If it has to be flashed from the SD card, how do I go about doing that? If it can be done from the phone via USB, does the phone have to be in recovery mode?
I have tried reflashing the ICS RUU multiple times w/ version 3.26.502.52 and 3.26.502.56, both do not fix the issue. Do the baseband and or radio files NOT get flashed within these updates?
Thanks for the response!

Thanks for the quick reply.
Your thread was the one I saw earlier with the simliar problem that I am having, only I have not loaded any custom ROMS. The phone just stopped receiving the signal the other day. I am still waiting for the download website to become available to use the tool to perform the flash of HBOOT, however, once I do that, will that erase the ICS rom from my phone? If so, what steps do I have to perform to get it in a "download mode" to accept the AT&T GB RUU? I'm a little confused on that part.
I read your first thread and I am a bit confused on exactly how you were able to correct the baseband/RIL issue (which I am assuming is the root of my issue). Do I have to extract some files from the RUU executable? Are the commands you provided to be used in ADB? I am confused as to what to do with [setprop ro.baseband 3.26.5XXX (<--- mainver: in android-info.txt in RUU.zip)] from your post. If that command is copying a file or just setting information (almost like as a registry setting within Windows) to point to the file or set a version number. Also if the XXX needs to have a certain number.
I thank you for your time and am trying my hardest to understand what to do to accomplish these steps.

I did find the extracted files within the RUU executable and found the rom.zip which included the .img files among other files I assume needed as sources to flash the phone. I see a radio.img file would I be able to do anything with that?
Thank you.

And I have a question, if the radio/baseband files are included in the RUU flash, what is happening as to why it is not being reflashed, or if it is being reflashed, why it is disabling the mobile network and providing an Unknown version to Baseband and clearing the IMEI number?

Here's where I am:
I successfully unlocked my bootloader, downgraded to GB, rooted. Tried to gain root access through adb terminal but it was not working properly.
I relocked my bootloader. Installed the ICS RUU AT&T ROM update. Unlocked my bootloader, rooted.
I see the commands you ran in your previous post. I am also receiving the same message of N/A when running the getprop ro.baseband
I tried the second command setprop ro.baseband 3.26.5XXX and then restarted the phone. I have tried it as posted, and also with swapping out the version that is located in my android-info.txt file: 3.26.502.56
Still no luck with setting the baseband version. IMEI still is cleared out.
Am I doing something wrong?

Hey thanks for all of your suggestions. I contacted AT&T the day everything happened to see if it was on the block list. They said no. I tried multiple things including trying to re-flash the radio, but I was getting a signature failed error that I could not get around. I really think that's what the problem is. I gave up and ended up selling it.

Exactly. It was my sister's phone. The sh*tty thing is we bought two off of ebay at the same time, 1 for me, 1 for her. Well, her phone was not in the box (either never shipped or stolen) so I had to file a claim through eBay which took 3 weeks to get the money back. Meanwhile, I gave her my phone (which is the phone in reference) to use instead. I bought her an iPhone instead now, along with purchasing one myself. I loved Android, but the bugs and fragmentation is getting too much for me to handle.
Dude, if you don't have an IMEI showing up, something is WAY wrong. That goes beyone the RIL not working... The RIL is probably fine. If your phone doesn't have an IMEI somehow, the cell towers are NOT, NO WAY, NEVER EVER going to register your phone on their network. You can put a billion SIM cards in there, or flash a billion stock ROMS, and if you don't have an IMEI, you will never be able to connect.
Something is probably corrupt or broken in your firmware or the hardware itself. I think your device is probably screwed.
My advice, is follow the steps to put your phone back to stock (including changing the bootloader message back to **LOCKED** and S-ON), and get it back to the phone company. They will be able to tell something is boned on the phone right away since it isn't displaying an IMEI.
Sorry to be the bearer of bad news and for your many wasted hours... But on the plus side, you now know a LOT about flashing and how your phone works now
Good luck with everything man! Hope they get you up and running soon!
I have the same problem as the OP but I have a IMEI showing up and a Basehand But won't connect to AT&T or anything they resent me a Signal & everything it shows a X with no bars it happened after I did a Factory Reset
anyone got the Radio.img?

That's weird..you try creating the apns again? I don't see how a factory reset would do that. Try toggling airplane mode too

I am currently having the same issues right now, it works if i leave the phone off for 1 hr it will work until i reboot then its down again, tried every thing possible, airplane mode will crash, reflashing the radios from gb and ics does nothing, setprop does nothing really. from this point it feels like a hardware issue.
sorry to revive an old thread, i just wanted to know if anyone came across this issue and had it fixed
i will get a log to see if there is errors showing up
Return it.

No phone signal

Hey everyone i have had massive problems with the IMEI on my i9000 finally managed to flash back to stock ROM but im still getting no signal. The IMEI is fine and i have a backup of the efs folder saved. What files do i need in this folder as i will delete all of the contents then start again.
Thanks
If your still getting no signal but are not getting "No Service" then either the modem you flashed in the stock ROM is utter pants for specific handset so trying flashing a different modem or a different ROM altogether :/
But if a different modem or ROM doesn't fix it then you have a antenna problem... sorry bud
Hey mate,
Cheers for the reply. I will try a new ROM can you recommend any small ROM's that will work on my device? I don't know a great deal abour ROM's and flashing in general tbh.
I need to finish my guides badly! Then I'd just be able to point you towards them :/
But since their not... cause I've been lazy, please head over to SamMobile/ and create an account if you haven't already done and download the correct firmware for you i9000.
Getting the right firmware is difficult, it's even more difficult since I'm guessing you don't know the PDA build from what the phone was running originally... for example by phone when I got it was running I9000BVJV7 which is actually Android 2.3.3 for the UK and sim locked to Orange.
When you take into account that the Android version, the country and the carrier have an effect on the specific firmwares for two (on the face) identical phones you can begin to see how many millions of different firmwares there are out there just for one phone...
So just try your best and read all the helpful info on SamMobile. If you get really really stuck or if something nasty happens to the phone while flashing either come back to this thread or PM me and I will talk you through a recovery kit that will hopefully restore the phone to a stock ROM (but not official stock ROM).
Since you're new to flashing please be reminded flashing can completely kill a phone to the point of no return, having said that I must have flashed a million times in both ClockworkMod and Odin but that doesn't mean death can't happen at any time.
Thanks mate i really am grateful for the help. I will give that a go and see what i can find.
Downloaded all of the vodaphone rom's and all of the orange roms. The device was used on vodaphone and im still getting the same error :/ any more ideas?

Firmware version blank/baseband blank/Imei null

I am lost. I have been reading through hours of material and am still not sure what to do. I purchased my att samsung galaxy note 3 n900a from a friend and it seems it use to be rooted. It has a custom recovery. I was able to verify the imei is good with att but had to use a program to locate it. My baseband is blank. It shows I have android 5.0 and that build is lrx21v. N900aucueoc2 4335446. But when I run a firmware test to see what I need to download (if that's even what I should be doing) it shows my phone is n900aucubmi9 android 4.3. My kernel shows 3.4.0-4335446. I'm not sure where to start for all the issues the phone has and I'm not sure I should download the 4.3 firmware when it's currently on 5.0. Please help.

Not sure what it takes to get someone to reply on this but ok..... i was able to get a sim card and put service on it and it has made the phone work every now and then. It keeps slipping back into no mobile network and stops working though. I have updated the apn settings to the correct options. Still when it turns the network off it goes back to no baseband showing, no imei, tells me to insert sim. I'm wondering if it has something to do with the custom recovery that I have on it. I'm honestly not sure CAUSE IM NOT ABLE TO GET ANY FEEDBACK.

I am no expert on this, and cannot offer much advice for it may violate the terms of this site. BUT, it sounds like you have a corrupt EFS partition, which is where the IMEI is stored. It is possible to set it right, but for that, you have to do your own research. Searching these forums for threads related to fixing EFS should be a good place to start.
Please note that I do not know if this is the case with your device. Its just where I would start my search. Good luck!

Help with IMEI Unknown

Good morning,
This cellphone is from a cousin which already sent this phone twice to techservice and it came back this way. Everything seems to be working except that it has no IMEI and no baseband.
What I know is it was never flashed with custom images, just official ones and it is currently with Android 4.4.2.
Any ideas?
Thank you in advance!

What I know is it was never flashed with custom images, just official ones and it is currently with Android 4.4.2.
Any ideas?
Thank you in advance!
