I9505 works only on 2G, no 3G, no 4G - Galaxy S 4 Q&A, Help & Troubleshooting

Hi all.
I'm asking for your help in solving my S4 (I9505 jfltexx) problem: it's working only in 2G mode, no 3G, no 4G.
This suddenly started 15 days after the last flash, when I installed the Imperium ROM (ver 10.1) with the Philz Recovery 6.59.
So, I begun searching, googling, following procedures, flashing modems, roms, but I can't solve my problem.
My IMEI is OK, the SIM works in another phone, with a different operator SIM my S4 behaves the same, so is definitely a phone issue.
The *#0011# Service Mode shows the LTE and UMTS frequencies and cells IDs and that, I think, means that the hardware is working and that the phone has a software issue.
Tried Imperium 11.0, LolliROM 6.0, Resurrection 5.5.8, Cyanogen 12.1, brand and no brand Stock (all Lollipop ROMs), different modems.
I didn't downgrade because throughout my readings (a lot) about this issue, no one solved the problem this way.
Tryed this procedure
http://forum.xda-developers.com/galaxy-s4/help/i9505-doesnt-3g-t2998527
with no success.
I forced the phone in WCDMA mode and, using the QPST and QXDM, I observed the event log.
This IMHO is the interesting part:
EVENT_WCDMA_L1_STATE----->L1M_FACH
EVENT_RRC_MESSAGE_SENT--->Logical Chan: UL CCCH Signal Msg Type: RRC_CONNECTION_REQUEST_MSG
EVENT_WCDMA_RRC_STATE---->Previous state: Disconnected, New state: Connecting
EVENT_WCDMA_PRACH-------->RF Tx Power: 24, Number of preambles: 10, AICH Status: No ACK
[this last event repeated several times until]
EVENT_WCDMA_L1_STATE----->L1M_IDLE
EVENT_WCDMA_RRC_STATE---->Previous state: Connecting, New state: Disconnected
A lot of people, considering just this forum, complains about this problem but I was not able to found a working solution.
I hope someone can help me because I don't have any further ideas or clues.
Anyway, thanks in advance.

New attemps made:
downgrade to 4.4.2, flash of various Kitkat modems, new upgrade to Lollipop, deep clean (here in italian http://bit.ly/1MRu7lk).
When I tried to restore an NVM backup, previously made by QPST, the procedure failed at 5% due to "Received an invalid command from the phone".
In this way, I completely lost the baseband functionality and the IMEI, without being able to restore them even with an EFS backup, made by Philz recovery.
I re-tried this procedure http://forum.xda-developers.com/galaxy-s4/help/i9505-doesnt-3g-t2998527 and the SRS tool. The only way to have back IMEI and baseband has been to go in a shop where the guy used a Z3X box but, again, without restoring 3G-4G.
I definitely ran out of options now.

same error here!
any ideia?

Hi, I'm having the same problem with my i9515. But, I think that my case is that this phone was bought in Poland and I live in Brasil, so, maybe is not the same frequencies, because I've tested a lot of things and nothing made my 3g or 4g works.
=/

Sorry, I gave up: as said, even with a Z3X box it was impossible to repair the phone and I stopped to look for answers.
=(

I have the same problem here. Everything works, wifi, network, but the Mobile Data is on gsm speeds. I think i bought it broken like this (2nd hand) as i tried various rom and kernel combinations with no luck.

The same happened to me, after updating the baseband. it's not a hardware problem

Emergency Calls Only, With Strange Twists

I have read a fair bit over the last few days on this subject & tried various things to try & resolve, but to no avail.
Ok so its an international I9300, unlocked & was working perfectly ok.
We have Italian & uk sims, both tested fully working in other handsets including a 2nd S3 identical to this one.
I had philz touch recovery 6.04, googy kernel 1.79, using slimroms bean & kat at various releases, no issues swapping between roms or kernels, defaulting etc, all worked fine.
Until I installed the latest official rom from Samsung I9300XXUGMK6, to test.
It installed fine, all via odin, factory wiped, caches cleared etc all as per everyother time I have installed stock roms for testing purposes.
It worked ok with my UK sim, but the Italian sim didn't work roaming wise, so I thought ok its probably a minor glitch, lets do clearing of caches, factory wipe etc, no luck.
So thought ok lets just go back to slimroms & be done with it, again it appeared to work fine with the uk sim, but didn't roam with Italian, thought that's strange.
So did fresh clean installs again, swapped UK sim back to handset & found now this has an issue aswell.
The strange thing is, you can add apn, access net through network as it connects via hsdpa no problem (giffgaff, aka 02) & it shows the mobile number, network as 02 in the status page of "about phone" however also in that page under "Service Status" it shows Out Of Service, although it is within service as in connects to the network fine for data, but no calls can be made.
Now I know you will think its an EFS issue caused by the upgrade/downgrade using slimroms & your IMEI & Serials are wrong now, but they're not, they're actually perfectly as they were before, verified with the labels etc & slimroms uses the same EFS versions afaik, so this shouldn't be an issue (please do correct me if I'm wrong)
I have tried flashing different modems, reflashing stock roms, slimroms, wiping completely, formatting, cache clearing, rooting/removing, kernels, but it still says emergency calls only, no calls possible, but shows as connected as data works fine & signal bars show fine (which maybe just for sos use).
So I'm at a loss what to try next.
My last thing I would do is send into service point, but 1st wipe, clean stock rom, triangle away the markers so all official & hope no hidden knox shows any 0x1 status, as nothing shows Knox as installed tbh.
Any experienced advice would be much appreciated, TIA.
Return to full stock, restore efs backup and test before any app/data restore.
If still the same then hardware fault.
Questions go in the q&a forum, report your post and ask a moderator to move it.
That's the negative thing, no efs backup, slightly annoying, but I think it can be resolved somehow.
Is there no way to fix efs apart from restore?

To update, the damn handset was blacklisted for no reason, it sent it into samsung & they tested, then sent back with the report, I was shocked, it seems previous owner had sold to a cash convertors store & then some months later claimed it was lost or stolen to which it was blocked in UK.
So I sent it back to supplier for a full refund, was a fair while back since I bought & handsets are now £100 on ebay, but I got my full £275 back, result
no imei and no backup

[Q] Serial Number changed flashing rom

Hello guys I need your help, Yesterday I was flashing MIUI ROM for my SM-N900W8 and it was not succesful, so I tried to restore the backup I did before flashing, but the problems started when TWRP did not allowed me to restore, it said Fail... after that I installed the Stock Rom from Odin and everything went ok until I was configuring the phone and when I was willing to connect to my wifi it appeared an error "Unfortunately Remote controls stopped" and the wifi turned to grey and I was not able to use it...
I flashed another stock rom (with operator) and the same issue, searching in the web I was a little deep about knowing what was happening and I realized my Serial Number changed, My IMEI is ok, but the problem persist. I need your help about this and restoring back again my phone. Thanks a lot
me too

I think MIUI messed my phone up too!
My phone stopped radio function. WIFI works fine, but my network isnt being picked up at all. The SIM works though. It saves and deletes contacts properly, but has no signal.
I have been scouring the internet looking for radio images and RUU's. Tried the RUU for my HTC One S, it downgraded my radio hboot...everything to an earlier stock version. Still nothing works.
it changed my device serial number into chinese characters. my phone number is displayed correctly under phone identity.
Anyone have a soloution to this??

In fact the S/N can easily be changed if your phone was rooted. But it is not relating to the wifi issue.
So you may have to try another firmware or another baseband.

Out of Service Network most of the time after flashing custom ROM

I hope I am posting in the right section.
I have a Samsung Galaxy S4 (I9505) and it was crashing on the stock ROM so I flashed the Imperium LL Rom v11.0. The problem I am having is my phone reporting no network signal or "Out of service". But not always. After a reboot I usually have network signal. After locking and unlocking the phone I never have. The signal usually comes within a few minutes. When my phone is reporting "Out of service" I cannot make calls but I can still receive calls. And after the received call has terminated I can still not make calls. After a few minutes the network signal icon comes and I can make calls. Until I lock my phone because it gets lost everytime.
Some info:
1. I was on a rooted Stock 4.2.2 before I flashed the Imperium LL Rom.
2. The IMEI seems to have changed. I never took note of it before flashing, so it might have always been different but the IMEI reported by the phone is different from the IMEI on the sticker underneath the phone battery. I tried the Xposed IMEI changer but the problem still happens so this may be unrelated.
3. While searching I found it could be an invalid Modem driver. In the settings the Baseband version is I9505XXUBMEA so I tried flashing the driver for that version using ODIN. No change.
4. I tried via Recovery to flash Slim80 Kernel Cleaning Script v1.9 and then the Imperium Kernel v3.3 but no change.
I did a factory wipe before flashing the firmware.
Any help or suggestions please?
Thanks!
I have actually solved this. What I had tried before was flashing the modem with the same Baseband I had previously ie: I9505XXUBMEA thinking that there were specific versions which needed specific drivers. Upon reading more I found out that newer versions of the modem should be installed and that XX was a carrier code and the last 2 letters are how recent the driver is. So I tried the latest modem (XXUHOE2) I could find similar to the Imperium Build which is XXUHOJ2 and it seems to be working. My phone retains the network signal when put to sleep.
The fact the IMEI changed is weird and I don't know if it makes a difference. Maybe it was always like this..but it is strange that it is different to the one on the sticker. The format is correct because only the last 4 digits differ.
Anyway I hope this info helps someone with similar problems.
How can I mark the title for this as [Solved]? I can't find any way.

Samsung Galaxy S4 I9500 - NO SIGNAL (IMEI/IMEISV:null/null;Baseband Version:Unknown)

Hello everyone,
As this is my first thread, and I have been reading previous assists based on IMEI fixing and couldn't find the answer I am looking for, I really hope that the XDA community can help me fix my Galaxy S4 I9500. I will try to explain the problem the best I can, and I will create a list of every solution I have tried in the 3 week phone fixing saga I have.
1. The problem :
My friend decided he does not need this phone anymore, everything was fine with it except the battery was swollen(but I bought a new one so it doesn't matter). The day before he gave it to me, he accidentaly dropped it in the toilet and it couldn't boot. I opened the phone, cleaned it with alchohol and the phone booted up normally. The thing I noticed was that in the status bar the network symbol was replaced with No signal symbol. I tried 3 SIM cards and none worked. I decided to downgrade to 4.4.2 KitKat version and this is where everything went even worse. I used Odin to downgrade a firmware downloaded from sammobile.com, but I didn't create an /efs backup because I have flashed an Alcatel Idol 2 before and there were no problems with the IMEI or so. It turns out that Samsung devices are different and I am left with NO EFS BACKUP. I know, I should have checked what to do before flashing the device, but what's done is done. The device is doing everything great, there are no problems with Wi-Fi or Bluetooth either, except I cant connect to a network because IMEI is null/null and the Baseband is unknown. The thing is, I am not sure if the IMEI is wiped completely because of a hardware problem, or it's software related because of the /efs folder, because I am not a developer, but a civil engineer...
2. Solutions I've tried so far :
- Flashed many different Android versions;
- Flashed a Lollypop with adonis.pit with Re-partition checked on Odin;
- Tried writing an IMEI and repairing the EFS with Octoplus box;
- Tried flashing an EFS backup from my friend's Galaxy S4 I9500 ( IT IS ILLEGAL IN MANY COUNTRIES, NOT IN MINE, BUT I WANTED TO TRY AND CHANGE THE IMEI LATER SO IT WOULD NOT BE A PROBLEM );
- Tried flashing with a IMEI_null_fix.tar.md5 file which i found on a forum and that didn't fix it either;
- Tried KIES to return the stock ROM but either it does not recognize my device, or it says that my device could not be initialized or so;
- Took the phone to service, but in my town the only service we have is not very professional and they didn't even know the IMEI null does not mean that I will have no wireless connection/bluetooth connection, so they didn't fix it either;
- Tried with EFS Pro, Terminal Emulator and programs similar to those, 3rd party and PlayStore ones;
- Maybe other things but I could not remember because I think I tried everything...
I don't know if the problem can be fixed, but deep inside me I hope that there is a solution, and I think this is the best place to search for help, because it is a great phone and I don't want to throw it away just like that.
Thanks in advance everyone, hope you can come up with a solution.

No network access (Moto G5 Plus)

Hi everyone,
I've been having a problem since yesterday morning. Everything seemed to be fine with my phone before I flashed a custom rom. I was using at the moment MSM Xtended and I flashed the latest version of CrDroid. After flashing that other custom rom and booting, my phone had no network signal. All it reads on the status bar after that is just "No service". Of course, I removed the SIM card and reinserted it many times but that did nothing.
I've already tried flashing another rom (the latest AICP rom) and even going back to the one I was using at the beginning, but still nothing. I even tried reflashing the NON-HLOS.bin file and erasing modemst1 and modemst2, but it didn't do anything either. I also tried flashing this deodexed stock rom and booting. Interestingly, that kind of fixed the problem, since it recovered its network functionality. However, after reflashing an Oreo custom rom, it loses it again (actually, I've done that a few times today, but the last time I tried flashing the stock rom, for some reason it didn't fix it anymore). I don't know if in this case it's worth mentioning it, but I've tried checking my IMEI on both, custom roms and stock rom, and it's never been 0 at any moment.
TL;DR: My phone lost its network signal after flashing a new custom rom and I have no idea why. If anyone could somehow help me, I'd be really, really grateful.
I have had this happen so many times it is not crazy LOL. The best you can do is find a rom that it happens the least. For me it has been AOSP extended. Signal has been great. It is a bug that I dont think the devs even thought would happen with 8.1 roms. It will happen to everyone at some point if we stay on these 8.1 roms i guess until we get a workable 8.1 stock rom. There will be those who chime in saying it nevver happen to them but it will eventually.
Well, it's nice to know I'm not actually the only one then, I guess. But is there nothing I can do? Since I can't seem to get it fixed even by flashing the stock ROM anymore and flashing AOSP extended didn't seem to help at all either
I know brother there is no rhyme or reason it just happens. I am hoping when 8.1 stock comes out for us there will be a new batch of 8.1 custom roms without this problem. Right now i am on extended and havent had any signal problems for a few weeks so who knows.

Okay. Luckily enough, Oreo stock ROM doesn't look like it's gonna take too much more to arrive... Or so I hope, at least. Thanks
I was using LinageOs and it was working great. Then I decided to install DolbyAtmos and for that I flashed Magisk . Suddenly i had no network but my sim cards were detected , IMEI was there but no network on either sim whatsoever. I tried reflashing the LinageOs and PixelExperience ROM but none worked. So I tried flashing(ADB) the stock firmware only to lose my IMEI . After reading this post I tried Debloated ROM and my network was back. I should have stopped at that point but I tried to return back to stock again and lost IMEI again and now I have tried Dbloated,LineageOs , PixelExperience , AOSP Extended , but none helped me getting back network . Now I am stuck with this phone with no network , I had a backupp of my system before I flashed Oreo ROMs (with EFS) so I can get IMEI back but no network. This phone was my daily driver and now I have no idea what to do.

Everything you said is exactly as if I had written it. I did all of that and now I'm exactly in the same position. No idea how to fix it yet. Still, if you managed to find a solution somehow, please write a reply on this thread again

No success yet , but read on some posts that different baseband could be an issue.
Solution I've tried and worked 100 %
Hi bodies,
You can turn off your phone,
Go to fastboot menu by pressing and holding power button and volume down button in the same time.
Roll to "Restart Bootloader" with volume up/down and validate with power button.
Now select start and the network is back.
see you !:fingers-crossed:
