I have an AT&T captivate and when I install any rom after stock I have no signal and no apns available (unless I am on stock then I have great signal). It will let me manually enter an apn but it will not stick. I backed up my efs folder from KK4 and replaced it once I went to new rom. I have tried it from stock going to GB, ICS and JB with no luck at all. I can get any rom to load through CWM but no matter what I get no signal and have been reading and searching for 4 days now. Any help would be greatly appreciated! NJD316

Do you have a modem? What does it say in baseband version (in about phone)? If not, that would be the first thing to look into (flash one).
Is your IMEI fine?
All is back to stock (using Odin) and modem works and imei is good. I can make calls and use Data and WiFi no problem and it picks up my MicroCell. It is when I upgrade to GB, add CWM and try to go to ICS or JB. I have tried CM7, CM9, CM10, and SlimBean 4.2.1 and 4.2.2 and any time I upgrade I lose APNs and it won’t let me add one.

Because you need to flash a modem after flashing the ROM. Those ROMs don't flash a modem, therefor, after you wipe, you have no modem.
I have tried several modems (6 to be exact) and every time I flash the modem shows in the baseband but stillk no apns or signal, WiFi is fine though.

APNs don't just appear, they have to be manually entered and saved.
I know apns don't just appear (on most roms) and they have to be entered manually, in the first post I explained that part . I do appreciate your help on this and your patience and I have had my share of modding my cappy and my sgs2. Basically = I can bring it back to stock (Froyo) and it works fine, if I upgrade to GB or later (to include flashing modems) it shows in the baseband that the modem is there but I have no signal, no apns show and I can manually enter them but they don't stick after saving. I have copied the efs folder that contains the imei and replaced it as many threads have said and it still does not work. I have gone through the process of stock Froyo to JB 4 times with different roms and results are the same.

Umm, can you try flashing Odin KK4 with bootloaders and see if they stick? That being stock GB 2.3.5
Been through the KK4 process and that didn't work either to get to ICS or JB.

KK4 is what you should be going back to stock with instead of Froyo, that way you don't flash Bootloaders over and over, pretty much removing the chance to brick your phone.
Once you have the GB bootloaders, to go back to stock, you should use KK4 without bootloaders. (As long as your signal and such is fine on stock GB).
Now, which modem did you try? On JB, you should be flashing the I9000 modems: http://soggycashew.weebly.com/cm7miui--ics-modems.html
I flashed the ugkg3 without any success. I will try the entire process again when I get home. Any particular modem you recommend before I try that one again? I am in Kentucky, USA and there are no points on the website map that is on the link. Thanks Bud.:good:

I can't recommend modem, sadly. They act different on every device and in every area. I have great results with JK4 in the past but it's outdated now.
SO my plan is to start with KK4 (without bootloaders) bringing me to GB, get cwm loaded, flash a i900 modem, make sure signal is good and then I should be able to flash a JB rom from there?

Almost.
If you're on Froyo, flash KK4 with bootloaders. From there, if you need to go back to stock, use KK4 without bootloaders.
Once on GB, make sure you have signal and all his good. Flash Corn kernel and flash the JB ROM you wanna try as per their full instructions.
Finally, try flashing some modems to see which one gives you the best results.
YOU ROCK! It was the corn kernel step. I went from Froyo to Slim Bean 4.2.2 in less than 30 minutes. Thanks Bud!!!!!
Help!

Hi, could you please describe in easier terms how to do it?
Yesterday I was able to upgrade it from 2.3.5 to 4.2.2 and I LOVED IT but got no signal no service at all... i had to take it back to 2.3.5 and today I will try to do it with another stable ROM instead of the nightly that I tried before.
Any tips for me? Thanks a loooot in advanced!
You got no signal and no service simply because you did not follow SlimBean installation instructions.

You may trip Knox counter, our locked boot loader only boots kernels or recoveries it approves of. Nothing stopped us from flashing kernels or custom recoveries, it is just that it wouldn't boot.
In addition you can't root it. Towelroot is a kernel exploit and it doesn't work on MLG kernel. Don't know for sure if you can flash the MLG kernel on an already rooted custom ROM and would still keep root.

If you're having wifi issues not remembering your password once you reboot. Go to this link http://forum.xda-developers.com/showthread.php?t=2793441and scroll through the post till you find wifi issues. Don't update your kernel then you will trip knox and void your warranty. You can also go to this link http://forum.xda-developers.com/showthread.php?t=2838117 and bring your phone back to factory. This second option will clear every bit of data from your phone so make sure you back everything up before using this option.

Are we still unable to flash custom kernels? On Araymod 8.4 rooted. I need to be able to install a good overclocking kernel but am having a heck of a time finding anything.
Custom kernels will not work with a locked bootloader.
Any way to show the carrier text? Mine doesn't show up.
You mean text messages from other people?
No, like in Carrier text on statusbar. It will say AT&T when I'm on the Hspa / LTE network when it hands off it should say AT&T MicroCell.
Hi, I have a Samsung Galaxy S4 Active.
When I make a call i get no sound, microphone and earpiece are tested and working properly(I CAN'T HEAR THE PERSON, THE PERSON CAN'T HEAR ME).
Also, no sound when I put it on speaker.
I tried installing another stock rom but the problem persists..
First time it happened I removed battery and that solved the problem, now even removing the battery won't make it work.
Please help...
Nobody??
i537 or i9295?
Version of stock ROM?
Method of flash?
Tried factory reset?
I9295, 4.4.2 Kitkat, tried to flash through Odin.. tried factory reset and no result.
Also, I've wiped everything (data,system,boot,etc..) before flashing with Odin, using a custom recovery.

As you said you have checked the speaker phone and mic and confirm that it works so this eliminates any hardware issues.
Did you do the factory reset from within the phone in settings or through custom recovery. Suggest that you do the factory reset from within the phone in settings (prior backup of your internal sdcard data is required as this will get wiped out) as this solves most software / firmware issues. If still problem persists flash the entire firmware through odin (download from sammobile).
I have the same problem in the service menü i have no issue but when i make a call it doesnt work (sorry for my english)
Is it possible to make a logcat too see whats the Problem ?!

Not sure if logcat will show the issue, but yes we can check it out.
Normally these issues arise due to either mismatch in firmware (flashing different modem) or issues in the ROM itself. You can check by flashing entire firmware and if issue still persists then do a factory reset from settings (not cwm) and reflashing the firmware.
Did you flash any firmware files / modem and are you on stock touchwiz or custom ROM

Mic in speaker is a known issue in cm11. This has been fixed in 17.10 version. You can flash the 17.10 version and check
Factory reset from stock recovery only wipes the system and data while factory reset from within phone in settings resets much more than that.
Reflashing only stock ROM will not help... You need to flash the entire firmware through odin .

It is always recommended to flash the modem for your region. ROM's generally are independent of region unless you have flashed the entire firmware. UCNE5 firmware so far seems to be safe and is known to work for most regions.
Which country are you from and which ROM did you flash.
I'm having the same problem, using CM11 or Stock.
Phone worked grate till 2 month ago (bougth on february). Tested different modems, different SIMS.
¿Maybe a hardware problem? ¿Maybe is bootloader/KNOX related? I think this as was using last TW from UK (I9295XXUCNH2), I'm from Argentina.

Flashing modem from a different region/carrier is sometimes known to cause this issue with certain carriers. Recommend that you flash only the modem for your region and carrier (not the entire firmware) and check it out else try flashing the entire firmware.
If mic and speaker is working fine in other apps then it will not be a hardware issue.

hmm..this is a tricky one.. You could try the NE5 modem from my drive to start with and see if it works, though I would recommend that you flash the one that you were on before while it was working properly.
Tested NE5 before posting, same results. Using official 20141018.
Original modem was 4.2.2, is there a modem repository?

Just one more question? are you using GSM or LTE, you could start by trying GSM mode only. Also just remembered this thread I stumbled upon yesterday which may be useful in unlocking the band used in your country/carrier.

Edit: another one which I searched and found today
http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269
Did a little search and you may refer to the below links for the bands for Argentina as well as those on I9295 which could be helpful

Yes, just Odin the unikernel from the unifed dev forum. After that you can use TWRP manager to flash TWRP. 5.1.1 ROMs are limited at the moment. I'm hoping someone will make a debloated TMo one. I unfortunately rely on wifi calling quite a bit so I need something TMo based instead of the international ROMs

Hi Everyone,
I am kind of lost in the upgrade process.
6 months ago, my Samsung Note 3 (USA AT&T) phone was working perfectly fine, but just with OLD firmware. ,then due to urge on upgrading, i searched so many sites and found a link somewhere on droidviews.com (as my firmware was NJ1 or something, website said i need to upgrade to NC2, and then to OC1), this process messed up my phone call receiving & making capabilities.
Most of the time callers see me unreachable and I am unable to call them as i get "emergency calls only"....I still don't have a way out from this issue. Some places I read i need to install right CSC / modem etc, I even tried this thread by reflashing using ODIN & N900AUCUEOC1_N900AATTEOC1_N900AUCUEOC1_HOME.tar. Even after this, i still have calls related issues same as above.
Can someone guide me to right direct (or) did i totally messed up with this? BTW, i am now in INDIA, using Airtel services...
I believe nj1 firmware is newer than nc2.

Thanks. I tried flashing to OC1, still same problem. my calls are mostly not working. Is there a way i can go back to original 4.3 stock rom that came with Note3 AT&T? or is there a way i can get current AT&T rom (latest) to try with?
Good part is, i can go between 4.4.3 and 5.0 as i have original stock roms downloaded. But bad part is, my calls still failing...
appreciate any clue/help.
Where did you get the stock ROM? AT&T never released full firmware for the 900a.
There is no way to go back fully to 4.3 since the phone bootloader can be downgraded to 4.3.

Hi, i downloaded NC2 & OC1 stock firmwares from XDA only. they are loading up fine (using ODIN). But my calling problem remains same.
So, Yesterday, i tried rooting the phone and installed AllianceROM. then i went into series of issues like "unfortunately NFC has stopped", "unfortunately settings has stopped" etc... then followed the instruction to wipe/factory reset, 3 to 4 times and disabled NFC services etc. As of now, phone works fine, but still need to check the calling function for a week...
thanks for your time.

Are we SOL with 900a? I was in the wrong forum earlier and was ready to use update to 7...until I realized it wasn't for me.
Dying on Lollipop (where I landed after the 7 fallout)
I re-read my post and noticed that I made an error: the bootloader on an n900a CANNOT be downgraded.
You cannot flash any ROM to the phone using TWRP, you must use flashfire. Only ROMs based on the stock Samsung ROM can be flashed to the n900a.
