Hi, i just got myself a Samsung Galaxy S4 and i have succesfully flashed several roms. But when i flashed back to the original firmware with Odin, suddenly my WiFi can't be enabled, and my speakers don't work. I have tried factory resetting, and a full wipe, but it didn't work. But when i use a different rom, the wifi starts working again.
if anyone could help me it would be great
known issue with MJ5 stock firmware, is this what you have?
Flash one of the Wifi Fix modems here with Odin. Make sure that the one you download matches the firmware you are running.
Hope that fixes it, if it doesn't work first time, flash it, restart phone back into download mode, and flash again. Had to do that with mine.

No, im sorry it didn't work for me, not even the doubleflash thing
I should probably just send it in on my warranty
I recently installed TWRP and then the latest snapshot of CM12.1 for my phone described in title. The android version was upgraded from KitKat (4.4 I believe) to 5.1.1. Everything works fine with the install except I have no network whatsoever. Can't text, can't call, can't use data etc. I made a post on the CM subreddit but didnt get a lot of help (can't post link) . Here is what I have tried: changing APN settings (which I have heard should at least let me call and text if incorrect); flashing various modems such as BOE3, BNL9, and BOD3 (all of them get a FAIL! (auth) in ODIN); restoring my KitKat backup (makes the phone unusable); trying to flash the default L rom for the phone (Also fail to flash in ODIN and TWRP). So at the current time I am basically stuck on CM12.1 and all of its amazingness with no phone functions, I basically have a small tablet at the moment lol.
Here is some information from the about of my phone, if it is helpful at all.
Model: SM-G900F
CM Version: 12.1-20151204-NIGHTLY-ktle (Installed the nightly after the snapshot didn't work, same problem persists)
Android version: 5.1.1
Baseband version: S902LUDU3AOG2
Carrier: Straight Talk
If any more info is needed, just let me know. I appreciate any help, as I am pretty much at square one still. I have googled for days to try to fix this, and haven't come up with anything. It seems no one has had this specific problem before.
If I can't fix this issue, is there any way I can downgrade back to what I had to begin with?

I only have one other sim card on me, and its through verizon. It didn't work on the phone either. I would definitely just buy a new sim card if that would mean it would work. The whole IMEI thing worked, but I am not sure what to do with that information.
(Definitely a G900F? Check what it says in download mode)
Checking the IMEI was to make sure you haven't wiped/corrupted the EFS partition, which contains the Radios needed to make and receive called, along with the IMEI (Hopefully you researched enough to back that up before messing with the phone)
Try flashing another stock ROM with ODIN 3.10.7, go for a different Lollipop ROM from sammobile. com
Some stock ROMs fail to flash, some work, (Phone dependant it seems)
Then boot into recovery and factory reset > try to boot

I have tried 2 separate L roms for the G900F. It says in download mode the phone is a SM-S902L and I read somewhere to get the true model of the phone you look at the FCC id under the battery. Well the FCC id says it is a G900V. at one point in trying to fix it, I tried a stock L rom for the G900V and TWRP told me that it was intended for a kltevzw device and that mine is a klte, so that is why I assume that it is in fact a G900F. I have been using ODIN 3.10.7 to flash everything as well. (Have't tried TWRP for the most recent tries since it takes longer to setup and I doubt it would work but it's worth a try I suppose.
I looked on Sam Mobile for the SM-S902L and there is only one firmware for it, which is 4.4.2, the same one it was installed with when I got it. From my understanding SM-902L is the straight talk branding of the G900V, and trying to flash that firmware didn't work either. Every time I try to flash something it terminates with a FAIL! (auth). What I also understand is that Straight Talk has not released an official version of L for the phone. So it seems my options now are to somehow get the modem to work right in CM12, try to somehow downgrade to 4.4.2, or wait for Straight Talk to release an update for my phone which is not really an option. I just got this phone and I really don't want to have to buy a whole new one just because of software problems. In my mind there HAS to be some way to fix this.
EDIT: my bad, I should have mentioned when I tried to flash the G900V rom it was also CM12, not a stock.
EDIT AGAIN: I seem to have fixed this problem. I have no idea how I did it, but I finally got it to restore to the stock 4.4.2 rom. I seriously have no clue how it worked but it did. Texting and data once again work, but i am now having a problem where I can't make or receive calls. Call immediately ends/goes straight to voicemail. I don't suppose you know anything about that, if you do that would be awesome. I'm gonna call ST in the morning and see if they can tell me anything from their end. But otherwise, I guess my problem is solved. Lol.
I know it sounds simple or may sound stupid but have you tried entering your APN? I have to do that with most of the custom Roms I flash or I won't have service. Also, make sure the correct modem is flashed and up to date.
I'd attempted (and succeeded) in rooting the s7 Edge without much of a problem, it seemed to be working fine. I was considering flashing a custom ROM as well, but before I could get to that point the phone started behaving oddly. It would refuse to boot, freezing at the AT&T logo screen and vibrating in a 1-3 pattern (1 vibration, then pause, then 3, etc., ad nauseum). I realised I still had ADB access at that point in boot (somehow, I have no idea) and used it to reboot to bootloader and see what I could do with Odin.
ALL VERSIONS of Odin I have tried (3.12, 3.12.3, PrinceComsy variants of both) have failed to restore the stock image and unroot the device. I have attempted to use multiple different stock images I've found around these forums and elsewhere, and all attempts have resulted in either the phone throwing an error about the Odin version I'm using, or Odin itself telling me that the flash failed and the phone indicating some strange message about the boot or the firmware being 'fused' or something. Exact error is SW REV CHECK FAIL : [system]Fused 3 > Binary 1
All I appear to have accomplished is preventing the device from ever booting properly -- it refuses to boot normally, and by default enters Recovery mode (the stock recovery, which is essentially useless and won't do anything at all). I would very much appreciate some help getting this device off the ground again; I'm sure we can figure something out together! As I type this, I am attempting yet another version of the stock firmware I've dug up, so... fingers crossed that gets some better results. If not... please help. Currently trying the APK1 version of the stock firmware.
Cheers,

You have to use either the stock version of the firmware that your phone was on or newer. You can't use any older versions. APK1 is the latest version i believe. Use the official Odin. The .12 version and you should be good.

Thankyou. It took me longer than it really should to figure out which firmware version to load. Downloading that now... fingers crossed, heh.
Do you think it's worth attempting to re-root and install a modified ROM on it for the performance tweaks that I've seen cropping up here and there? Or should I just count it lucky it's still mostly salvageable?

Depends on what you want. Personally i would root it and go to the Verizon forum and download Stang5.0litre rom. That's an awesome rom. I'd stay away from echoe rom, seems like the devs are hit or miss on support. The dev for the stang rom is awesome and very active. I ran both of then and prefer stange.

Yea it works. I know that one does. You'll get a message that says "unauthorized SIM card: or something like that. Just ignore it and use WiFi to setup the phone. Once you have it setup use package disabler or titanium to freeze "setup wizard" and that'll get rid of that notification. You'll have to manually setup your AT&T APN. After that your golden.
I have lost the phone that has been working for ages. I am broke atm. Please help I need to use my phone. I was trying to get my radio to work again because I lost data a couple weeks back. So I have spent more time than I even should have for this trying to fix it.
I have run Odin 3.07 with

lineage-14.1-20190212-nightly-jfltexx-signed
and
open_gapps-arm-7.1-pico-20190209
I have wiped everything and tried 2 different system boards ;
from download mode I have
used I337MVLSGQB1_I337MOYAGQB1_I337MVLSGQB1_HOME.tar
to reload with nothing checked but F. Reset Time.
pulled out the cable then the battery.
went straght to recovery (system was going there already) to do first stage unpack with android and progress bar.
It said BAR and END
I went in back in after restart, and a full wipe.
And after a long wait .. the system very glitchy, slow like something was running in the background (modem ?) if I open the phone app it wont close and calls are silent. then resets over and over..
I have tried custom roms, and flashing latest modem and original ? Whats up ? anyone
PLEAESSEEE help soon .. I am going crazy cuz this is literally my only phone and I need to use it !!!!
Had an old system board and tried to replace it and ended up in the same place with the second board ?!?! what is going on !

I ended up using the pixel experience rom. I am sure I have the wrong bootloader and modem for i337m though. It works with data when I reset network settings and re-enable. Data each reboot. For the longest time lineage 9505 ROMs worked until like Feb 5th I saw the data just fall use just fall off. I couldn't get chatr to work anymore. It was a nightmare I went to stock and , pitted the phone and it would only function until I added TWRP and tried a nougat rom or even with latest modem. Wifi was evn a problem. Now I am using like a lollipop bootloader with the green battery charging and modem isn't right. When I flash a different modem and bootloader in Odin and rip the battery and then cableit doesn't even change .
Wtf?

I'm not sure how you could flash the wrong bootloader unless it was flashed using TWRP or CWM. To confirm, boot into download mode to see the model # listed on the screen.
Are the modem and bootloader matched; i.e. the phone is running a 5.0 bootloader and modem? To easily ensure that both are matched, you can flash the latest stock ROM using Odin.
If the modem version is not changing after being flashed, it is possible that the internal memory is faulty.

Did something happen to it, or did you just notice it is not connecting?
The most easy things first, is your sim card correctly in place?
Which ROM are you on and have you reflashed it?

The phone started with problems since I upgraded to Android Pie, I have taken care of it very well but I do not know if it is a hardware failure, but note that in baseband turns out to be unknown, I installed several stock roms from fastboot without any success, also I thought it would be a problem of the EFS partition, but everything is fine I even took a backup in case the doubts, what could happen?

Did you originally update via OTA, meaning, was it the official update?
Then when you noticed it's not working, you tried to flash several stock ROMs?
One possible problem that comes to mind, is that for some reason, you have the wrong radio/modem firmware. That can happen for example, if you have flashed a ROM, which is not meant for your region.

Yes, upgrade to Android pie via OTA
I already put a stock rom of the same region, following each fastboot command one by one, but everything continues the same, I even installed RROS 7, to see if at least it turned on the wifi, and it is in bootloop.

Go with the modding guide index: how to restore stock ROM etc., and flash a stock ROM that you know will work. Flash the radio/modem file too, and make sure it's the correct one.
Just to say, I had connection problems too, and in the end they were because the sim card did not latch correctly in place i.e. was not correctly in place.

Great that you have an idea. ?
Here's an idea: take a backup of your current config in twrp, move it to the computer, take a copy. Replace the files in that copy with the ones that you want to flash.
Did you mean this? You are aware that you can try different radio/modem files through fastboot, not having to flash everything else every time? That said, go with your idea. ?

Hello, colud you solve the problem? Because I am havig a very similar one...
Hello group friends, I'm new here. I have a similar problem, I was using the Havoc 2.4 rom, when upgrading to 2.6 I no longer recognize my SIM card and the wi-fi does not connect, I can not install another rom anymore, nor rom stock, recovery TRWP has been replaced by the Havoc and the Wipe System function does not work, and for a few days you can not stay in recovery mode anymore, it restarts every 3 seconds, not the time to click the options. Can someone help me. I'm without a cell phone, and I need it.
I have a similar issue after flashing the latest firmware. SIM goes to "SIM locked" every ten seconds or so, and Wifi drops at the same tie. It's like networking is being reset every 10 seconds. No network settings I've tried change that.
I've flashed several stock ROMs; the one I had previously, newest, oldest, both for RETEU and retail. I used Lenovo restore to upgrade but that resulted in soft brick, after that I flashed the latest firmware via Fastboot and that's when the problem started.
With Oreo, wifi and cellular don't work at all, nothing detected. With Pie they're connected and dropped in a loop. I can't help thinking that the Lenovo restore broke this somehow, but modem files have been reflashed several times after that with no change. I'm not getting the baseband error.

I have the exact same problem, I wasn't able to repair it so I sent it to service and tomorrow they will try to fix it for $35. The problem with goign back to previous versions is that you loose the IMEI and MAC . The problem with the pie version I believe is the baseband. If the service is able to fix it I will post the solution here for you to fix it .

Sorry I answer so late, I didn's see the message before.
I believe you already tried puting it into bootloader mode. If that's the case, I had a similar problem recently an it solved alone, I let it loop for a while and suddenly fell, into dtock recovey, i factory reset (with stock recovery) and somehow stock was booted ( i believe it was because it was in inactive slot).
Hope this helps you

I am still working on this, I actually did this to a work phone (I had permission to root/unroot). Something that has helped me so far is just getting familiar with the whole flashing process - https://android.gadgethacks.com/how...actory-images-android-using-fastboot-0175277/. I think from this article the problem lies in the modem/radio rom. That *should* be the only thing you need to flash on. However, I have noticed with a lot of roms on here, a modem rom is not included on the stock firmware. But that needs to match well to your phone from what I understand. I have tried a few modem roms already, unfortunately, but no luck.
