Hello all.
I am having some issues with my Galaxy S4.
I have read through a lot of the signal loss threads the last couple of days.
But I'll explain why those were not helpful to me.
I started by rooting my phone with cf auto root jfte.
Via Odin 3.10.
I then installed twrp and some cm roms.
And experimented with a few different roms and software.
I wasn't bothered about bricking my phone.
I think I did soft brick it a few times but thanks to the help from xda threads I got it back a few times. So thanks for that guys.
Now I am running an official EE rom and modem.
Everything works perfectly and smoothly I am no longer rooted.
But no longer have any signal.
The imei is in tact.
The sim is being read by the phone and also knows what network it's supposed to be on etc.
The phone can search and see the networks sometimes but cannot register on them.
I did try an app while I was patting about with roms called region lock away. As some people said it can some times network unlock the phone.
And it seemingly did with mine.
However a few roms later and I cannot revert whatever it done.
Any ideas on how I can get my signal back would be greatly apreciated.
Thanks.
Andy.
Can anyone assist with this?

Hello all,
I am relatively new to custom roms and flashing my phone, I'm trying to learn as i go but I've found myself stumped.
I've recently flashed goldeneye rom, and ive been having issues with my signal strength, if my phone is even in my pocket i with have no signal
I previously ran cyanogenmod 11 and had no issues
I am on the MTS network in Manitoba, Canada
my baseband version is
I337MVLUAMG1
I'm getting confused when i try to look into all the different modem version
anyone have any suggestion on which one to try?
did you follow Canadian install instructions in OP. IE--Kernel Fix
Hello, I´m having the same problem with the signal.
I can´t find the fix you mention, would you be kind enough to point to it.
The rom is very well done, the only problem for me at least is the signal when the phone is with the screen turn off and i lose all signal.
I've been experiencing the same trouble with goldeneye and echoe illusion rom. As soon as I stop using the phone line or internet, the connection usually goes away after 15sec to 2-3 minutes. I have to ask the phone to look for signal again and choose the service provider to get back service, which usually takes 30sec. When I click on my service provider I get back to 3-4 bar signal strength instantly.
I can't find that link. You will have to research it.
You guys should really start your own threads in Q&A. Hijacking one makes it hard for others to follow with 3 different posts on maybe 3 different solutions. It may or may not be the same answer for all of you. One may just be not a clean flash. One may not be flashing correct modem etc. I am not on i337m.
When you start your thread give all your info like phone info, how you flashed, any details on what you did to fix, build number etc etc. More the better.
Good Luck--:good:
if you're on kitkat based rom but still have jelly bean modem you will have signal drops. when I updated to kk I first flashed the modem alone (NC1 in my case) while still on jelly bean and then I updated to kk based rom.

Hello guys. I have the n900t, I am now running tweaked s5 base n4 style v6.0. And I run alot of n9005 ROMS as well. With that said here is my issue. For only the past few weeks ( month tops) every time i make or recieve a phone call my data drips down to hspa. The second i hit call and right before my phone rings is when it happens. After my call the data takes a very long time to jump back up. This is a new issue and i have no idea what it is. However, i did flash back to a stock ROM and the issue was solved. And i forget which rom it was but it was soley TE based and there were no issues. I did try to flash a modem but it didnt take. Is anyone else experiencing this problem? Or can anyone suggest a fix for it.
Thank you for your help.
bump.
Still having the issue. I tried to flash a new modem and it just failed anyway. Dont know if I should try a radio. I just cant fivure out why this happened out of no where. I was fine no matter what ROM I was running. Now...this crap. Please guys, 40 people saw this, can SOMEBODY please help.

1) Quite strange - your picture suggests you are on Verizon yet you comment about a N900T in the forum for the INTERNATIONAL Note 3. On what network are you? Are you aware that there might be network-specific factors involved which could only be visible for other users on exactly the same network in exactly the same region?
2) Try stock ROM (with corresponding stock modem) from a location with very good signal.
5 he physical device is an n900t, however, I am running as of now, the hyper drive note 5 port with n4 UI. When I do flash back to a full stock TW ROM all is good, A FEW TW based ROMs seem to be OK. Like this one, the calls do not affect the data signal. But most ROMs do effect it in that way. You said that it shows I'm running Verizon?
But I am very curious why all of the sudden I am having this issue. I have never had it before. Except with a few specific AOSP based ROMs. I just can't figure out what it is that's causing it. I have done vigorous wipes of the phone to no avail.
And I am in Philadelphia so there really is no place that is actually bad reception (except in the susubways of course...lol)
And thank you for your reply.

1) Your avatar mentions Verizon for some reason.
2) If it is all OK with the stock ROM then it is a problem with the custom ROM, ask in the specific thread for that specific ROM. Most likely it has something to do with the modem and the corresponding RIL.
So when ever a new ROM is flashed the modem is flashed as well. Unless the dev says otherwise?
Hi guys
My phone was rooted but never flashed a ROM on it. Today I updated my phone to Lollipop through Kies Mac. After that my signal is not there. When I reboot the phone I get signal for few seconds then it gets lost again. Also phone never saves my Wi-fi connections.
I did reset my phone but still the same.
It was locked to Vodafone and I unlocked it in Vodafone shop when I first bought it do you think anything related to that?
How can I downgrade to KitKat or get my signal working?
Same here. Do any of you guys know how to solve this issue?

Please use the search function of this site and google, don't be lazy. There is a thread about downgrading . Also try flashing lollipop modem/bootloader, for this visit any of the TouchWiz Lollipop rom threads (like the one in my signature) most of them talk about flashing modems and bls.
Hi at all! I'm new on this forum, so I hope I didn't break any rule. Anyway, I'm trying to recover a friend's phone, a Samsung Galaxy S3 (i9300) International Version.
He said he installed a rom called "Android Revolution HD", which appears to be an improved version of the stock rom. Anyway, now the phone does not register on the network.
The IMEI in the settings menu is correct, also the signal appears to be ok, but when I try to select a network, the phone does not register.
So, I tried almost all the solutions I have found on this site, from trying a bunch of different modems, to installing the whole stock ROM (Android 4.3).
But none of these worked. So, there is a real solution I can try?
Thanks in advance!

I have the same problem for months now i have tried a lot of solution but nothing works. i am hoping a senior member can help fix this issue. And just incase some has a viable solution, they should kindly help out. :fingers-crossed:
What I think is you've updated it from 4.1.2 without any EFS backup. Well I had been through the same situation and couldn't find I single thing. In the end I had to get my S3 repaired from a local shop. I think you should go too.
Hi first post here but not a complete newbie. But this time I'm stuck big time and would appreciate some help.
I've got a s8 plus that recently started playing up. All of a sudden it started not being able to make or receive calls. But I noticed it only happened when the "conditional call forwarding active" message didn't appear when dialing. I figured it had something to do with call forwarding so try to change the settings on supplementary services settings but when I tried to enter the settings an error message appeared "failed to read data" I tried sending the code manually to cancel voice mail *#022# to see if it would work but I got "connection problem or invalid mmi code" so assumed it could be that the phone is trying to check with the network the forwarding settings as the call starts but for some reason it cannot communicate with it as the mmi codes don't seem to working?? (I'm not that knowledgeable in that area) I tried all the fixes online for the "connection problem or invalid mmi" but none work so I flashed the firmware through Odin even tried a few different ones, I've been playing around with Odin for a while so I'm comfortable with it, I even flashed a pit once for a note 4 that was bricked (just saying so you can see I'm comfortable with using it, not an expert just comfortable) but nothing has fixed my problem my phone is a g955fd running pie and one UI with the latest security update. I've read the duos have some issues with this. I've tried other sim cards on my phone from different carriers and the problem is the same and I'm using my sim on a borrowed phone and no problems. I'm assuming the problem goes deeper than the firmware, could this problem be boot loader related? Would a nand erase and reinstalling the boot loader fix it? Everything else works 100%
Someone please help me, the phone I'm borrowing is an apple and every day I have it I feel weaker and dumber, it's like kryptonite.
Sorry for the long post but I've been browsing xda forums for years and I know that you guys always say to share as much info as possible. By the way I've searched and couldn't find a thread about this but it there is one I promptly apologize and just ask for the link to it if not thanks in advanced.
? G935F or G935U exynos vs snapdragon
Way for snapdragon
Flash https://forum.xda-developers.com/galaxy-s8+/development/rom-t3901074 with odin and test with hard factory reset recoery.
After, flash odin last firmware stock sammobile
Thanks
Thanks for your reply deadedge7
As I said my s8 + is a duos g955fd variant and has an Exynos processor, I'm not sure that rooting it would make much of a difference, as to my understanding rooting doesn't really change the boot loader it just allows you to install a custom recovery and roms. Which is not much different to reflashing a stock rom for all intents and purposes , but I might give it a try anyway. I guess that maybe a rom like the one in the thread you shared might give me some more hidden codes access as a root but I'm not sure. I will try to find a root like it for my variant unless you know of one and can point me to it.
Thanks
Hard reset or flash stock software or hardware problem
For iemi best way is root efs with flash twrp best way for /EFS

No solution so far. I've rooted the phone and install a couple of custom ROMs but still nothing. I'll try and roll back the firmware and see what happens. I'm no expert but I still think it is fixable. If I find a solution I'll post it on this thread. If you find one please share. My solution at the moment is getting a galaxy A50, very comparable performance with the S8 and really cheap.

I'll keep that in mind. Couple of things to note: I don't get the message conditional call forwarding active. I don't think I ever have.
I tried a different carrier SIM card(T-mobile) and it worked (I'm on At&t). I was able to make and receive calls. Even tried an out of country SIM card and received calls. But my At&t SIM works on other phones perfectly. Go figure lol.
The only other reason I can think of is maybe cos it fell a couple of times from the couch. About 1.5ft. New case kept making it slide off.
