Hi,
I've read dozen of similar threads but no solution so far.
My phone can't connect to 3G at all. The moment I switch to only WCDMA phone drops network completely.
Everything else works without a problem. I've tried other sim cards (same and other network) no difference.
Baseband and IMEI are OK.
I've tried flashing modems, stock firmwares and it's always the same.
Current state:
AP: I9505XXUFNB9
CP: I9505XXUFNB9
CSC: I9505OXXUFNB2
Please help, I'm running out of ideas.
1. Make a backup of ur Internal Memory
2. Make a factory reset (Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything.)
3. Conect it to Kies 3
4. Kies 3 will give u the info you need for know ur correct CSC. This will be btw parenthesis close CSC.
5. Knowing ur CSC, take a look for this firmware in Sammobile.com
6. Download and flash it with ODIN (Dont flash a "Black EDITION" if ur phone isnt it)
7. If this not work, you can get it to repair :highfive:

Did already this before posting. I've read pretty much all threads with similar problems. Thanks anyway.
Any more ideas?
Maybe flash box can help it? At this point I'm really frustrated for not being able to fix this. Had several androids before (s and s2 also) and always managed to repair them. First time for everything For sure I'll take it to repair shop on Monday.

Same problem here. I have a S4 i9505 free of carriers. No 3G signal, only EDGE (2G).
I updated modem, nothing happened, Then updated firmware to the last one, and nothing. The problem is still there.
What can I do?
Last firmware installed: I9505XXUGNI2
When did you start experiencing this? Did you update your firmware and suddenly this happened? I too have the same problem. It started when I did sim unlock. I'm not able to fix it up to now.

In my case it was damaged EFS partition. The only way to repair it was using Box. So I would suggest the same to you. At least you'll save a lot of nerves

HI, thanks for your answer.
What is Box? How do I repair EFS partition?
In my case (actually, my friend's phone), it connects to EDGE and it can call to any destiny. Sometimes, loses signal, but with the new firmware, it appears that works better. But no 3G/H+ signal.
Maybe she can go to the service (SAT) ... and they would repair the EFS??
Thanks for your help.
PS: Sorry for my english. I speak Spanish.
We have the same problem. I already brought my S4 to the official samsung service center. Only thing they did was flash an updated ROM from my carrier. It didn't solve the problem as expected because I've done the same already before taking the phone to them. I also already flashed different modems with no luck. This is getting really frustrating. I wish you luck in your search for a solution. Subscribing to this thread.

Box is device built based on reverse engineering of mobile phones allowing user to perform more advanced service operation (for example EFS repair) on handhelds/cells. It usually comes with special set of cables for specified vendor. Google for example 'z3x box' for an idea. It's cheaper for you to bring the phone to some service shop which has box for Samsung phones. They can settle this in a matter of minutes.
Sorry for the late answer, been very busy lately.
I was digging for like a week or so, because i have the same problem. ( i have 2g / gsm signal, but when i switch to wcdma (or 3g) only, i was getting no signal at all. (the circle with the line in it). My imei is not broken/missing, and from all the forums i've been digging i came to conclussion that there are several possible solutions as i think, but im not too deep into that matter, so im just sharing my thoughts, dont try these if you dont know what are you doing, i say again, im not completely sure if any of those gonna actually work.
1st - EFS Proffesional (along with Qualcomm NV Tools) - which can be found here, in xda. (The program itself has a ****load of options, and i dont have the knowledge to operate with it). Qualcomm NV Tools is a part of EFS Pro.
2nd - the secret code menu - Service Mode ( *#197328640# ) - I wasnt able to enter it at first, so downloaded the Shortcut Master (lite) (free in Play Store) and found it there, launched it with option 0 (launches a code with root priv) and i entered the service mode.) i've explored it, there are a lot of settings there, like backup, restore, rebuild, changing bands and so on and on and on, and somewhere inside it, there MIGHT be a solution inside those. I'd like to hear something more about those options from someone who actually understands them.
Other option is JIFF BOX, which i dont know how actually found, it seems that program requires qualcomm usb drivers for PC, and i think this is something like virtual box or w/e it is, i couldnt run it, didnt have time atm, but this program is given to wake up even completely dead sgs4 somehow, so why not bringing back the 3g?
And the last thing ive found - SRS - (found it in sammobile's forums. Some kind of imei/efs/baseband/etc restorer, reflasher or w/e it is. But this is paid program with free trial for unlocking the screen pattern. )
At last, you/me, can always go for a service with box for samsung phones and pay for reflash/repair. Is this the only solution?
Forgot to tell - im using i9505. simfree, no brands etc....
Can't edit previous post. This is the actual service mode code, don't know what are the prefixes and suffixes, I'm running it with root and shortcut master lite. It seems playing with the settings can help, but we need ppl who can really understand these settings. If you need / want, ill make more screenshots.

I was also able to read IMEI and have used EFS Professional and NV Qualcomm tools but without success. EFS partition was damaged anyway. So yes box is the only solution in a majority of cases.

Can you explain a bit more what have you tryed with EFS Pro and NV Qualcomm tools?
To others: What about that secret menu? Can something be done by the options inside?

Your digging around has misled you. The GT-I9505 has 2100MHz support for 3g, as noted here, here, and here. It also has 2100MHz support for LTE. So something else is causing your issue. Are you certain your phone isn't in fact getting an LTE signal instead of 3G?

So in my country all service providers work with 3g at 2100 frequency, why does my s4 doesn't connect to 3g?
Well... sadly after digging around i found out that the phone doesn't support 2100 frequency.
It's the official firmware for this country, was bought in this country but only gets 2g and 4g
any way to solve this mess? most of the data signal comes from 3g signal, if i'm inside of a building i only have gsm data :crying:

Based upon the information you've provided, you're on the Baltic Black Edition firmware (CSC SEB). The firmware here though doesn't appear to be the problem. The problem is that you need to clear up some confusion here. You're saying you can't get LTE, are using unbranded firmware, yet your phone is locked to a carrier.
In an attempt to clear up things, please provide us with the missing information below, and confirm any already provided information is correct.

NOS (formerly PT Multimedia, ZON Multimedia and ZON Optimus). You will have to flash the latest firmware for your locked device. Download, unzip and flash this firmware via ODIN: HERE.
thanks but as i said before, i've tried many stock firmware, including that... that was te first one because i also thought that was something related to simlock
i will send the phone to warranty, or try at least
@Joku1981: If I didn't have to work today I would have told him the same thing.
@monteiro-ribas: If you intend on having the phone swapped out, you might want to flash the correct firmware that Joku1981 provided the link to before sending the phone in. I do hope you let us know if you get your issue resolved and whether it actually was the phone or, alternatively, the service.

My original post in modems:
Ok guys, my kingdom for a solution, please !!!
Here's the deal, I have a samsung galaxy S4 GT-I9505 bought in hong kong, worked flawlessly for over a year on Telcel Mexico network, took a trip overseas to France bought a sim put it in the phone, worked great !!!!, came home put in my original sim and since then my S4 has been unable to maintain a stable 3g connection, usually connects for a under a minute and reverts back to edge. I've tried many different things recommended on this and other forums:
1.- removing/replacing sim card
2.- removing/replacing battery for over 4 hrs
3.- tried different sim cards from different carriers with same result
4.- wipe and clean install with different firmwares
5.- installed cyanogenmod latest
6.- under network modes, tried selecting every combination of lte, 3g, 2g, automatic network registration and selecting my preferred network.
7.- tried flashing over 30 different modems
8.- flashed latest firmware from sammobile specific to my phone (I9505ZHUFNL1_I9505ZZHFNL1_TGY)
9.- took it to a "technician" and he managed to return my phone in the exact same condition with the exception that now the wifi didnt work (i managed to fix this on my own)
10.- installed advanced signal status from play store which gave acces to other goodies such as selecting radio band between automatic, europe and usa, tried everyone of them with no solution.
Tried to be as thorough as possible, hope someone out there has a solution. I thank you all for your time and experience. Happy Holidays !!!!! I hope I am posting in the correct area, i searched and found this is the place where my problem seems to be discussed
P.D. Since im flashing GPE right now the screenshots no longer reflect what im on but I do have a nandroid back up of this rom and I am about to restore it.
Hope I was thorough, thanks for any help

Hello, i need the steps to. the link is broken.
By
I had been looking at this phone for a while on ebay and despite well... ebay... I had temporary lapse of good judgement and maybe a bit of alcohol and pulled the trigger.
I got the phone thinking it was a SM-N910F, everything I'd read said it would work on US AT&T sans some bands for LTE.
The phone came and it was in good condition. The box and the serial label behind the battery all say SM-N910F.
I turned the phone on, it has a beautiful screen, everything seems to work fine, works with wifi no problems, so far so good.
I turned it off, popped in my ATT SIM and turned back on and, uh oh, got an invalid SIM error.
Ok so next step, I go to the ATT store, they check the IMEI and confirm that yes it will work on their network and they give me a new SIM for good measure. Their new SIM still shows invalid in the phone and the sales guy is confused but then I tell him I got the phone off ebay and he gives me a look of pity. No problem though I wanted the international phone so I could learn about flashing ROMs and such without leaving me with a non-working brick and no communications device.
So I read through XDA posts and various tutorials over the web and try to find out why it's not accepting my SIM.
I flash TWRP, and root the phone, that worked fine.
Then I decide that maybe upgrading the firmware to Lollipop and flashing a new ROM might fix the problem. I go to Sammobile, download N910FXXU1BOB4_N910FOXA1BOB4_DBT because that seemed like a good one that would work. Then try flashing it via ODIN.
ODIN Fails, SECURE_CHECK_FAIL : aboot. Some more reading later I find out that usually happens because you're trying to flash the wrong thing.
So I dig further. I can still get into the stock kitkat software on the phone so I download *Samsung* Phone Info and check out what I've currently got on the phone, but now I'm totally confused because I don't know what to make of it and this is where I need some help.
I've got screenshots but due to being new I can't post a link, I can email them if they'll help.
Settings > Device Info shows SM-N910F with baseband of N910FXXU1ANK4... that looks right
but then I fire up Phone Info and it shows a phone model of SM-N910P which would be a Sprint CDMA phone? and a country CSC of CHN?
so this phone is truly international
European phone, Chinese CSC, with USA Sprint firmware?
Where do I even begin, can anyone suggest what I can do to untangle the mess?
Have you check the box "OEM unlocking" in the developer options menu? This allowed me to use Odin the first time on my tmobile note 4.
If you don't have a developer options menu in your settings, go to about device and press build number 7 times until it tells you you are now a developer.
try a European version BTU from sam i have the same model SM-N910F root is an issue i'm looking at.
as the SM-N910F is Euro i would use that firmware.
Hope it helps.
Hi I'm looking desperately for help with these 2 major isssues, any advice will be much appreciated.
I recently bought this phone SM-N9005 and worked perfectly until I realized my gps doesn't work properly. After a brief research I discovered a youtube guide with positive responses so I gave it a shot. =hC8jNb38gaY . This included ServideMod digging via *#9090# -> insert Q -> insert 0000 -> UE settings -> setting -> system -> NV rebuild -> ALL . After that my sim card was no more functional just as any other I then tried. So this is my first major problem:
1) INVALID SIM CARD The sim card was doing just fine before that and is still doing when put into other devices, but no matter which sim card I try the problem still persists. So I tried factory resets, loading different firmwares... which led to problem:
2) CAN'T LOAD DIFFERENT FIRMWARE I think I was doing all accordingly to guides but still can't force my phone with different firmware. I got it rooted, and everytime I try to use Odin it just gets stuck at "Complete write" fail or FAIL Auth.
The only firmware I could load into it was the early leak of loli 5.0 N9005XXUGBNL8 . I then tried several of them so I could use for example AryaMod (which gets always stuck shortly after start of the installation - i think because i cant load demanded firmware) but to no avail. The so far tried firmwares were the stock ones;
N9005XXUGBOJ6_N9005XEOGBOJ1_N9005XXUGBOJ1_HOME.tar
N9005ZSUGOH3_N9005OZSGOH3_N9005ZSUGOH3_HOME.tar
N9005XXUGBOI6_N9005ETLGBOA2_N9005XXUGBOH1_HOME.tar
N9005XXUGBOI6_N9005O2CGBOF2_N9005XXUGBOH1_HOME.tar
And the only working is the one mentioned above from early loli 5.0 leak : BL_N9005XXUGBNL8_CL3643614_QB3415922_REV00_user_low_ship_MULTI_CERT.tar, which I currently have. Any other attempt to load meets with the same failure. I tried different versions of Odin, starting them as admin, different usb ports, wiping before, rooting it but just can't load any other. : /
So finally I'd like to ask: Is there any way to revert damages I did by doing that ServiceMod thingy? To get rid of that INVALID SIM CARD notice? I'd like to do it myself if possible.
And secondly, why can't I get any other firmware working? Is it wrong choice of firmware not compatibile with my phone or I just overlooked something during installation?
If you reached it all the way here, thank you. Please share any advices you might have.
Oh btw this is from *#1234# if its of any help : AP: N9005XXUGBNL8 CP: N900PVPUEOC5
What is the model number in download mode? Does the imei in the phone match the imei on the label under the battery?

...Well this is odd, the model number is everywhere stated as N9005 but in download mode it's N900P !
The mei number matches but it's short of one last number. The mei in back has 14 digits and in system 15.
Hey,
I got the same issue a few months ago,
It was the "pin" behind the cover that didn't reach for the antenna on the other side
This crappy video helped me a lot
https://www.youtube.com/watch?v=iUsXU28IDdM
Update: I just discovered I can only install the N900P firmware so right now the both AP and CP is N900PVPUEOK2.
But the firmware selection for 900P seems rather limited to USA region. Back then I had czech (maybe european version with czech language?) version.
Info about phone now says my phone is N900P even though my phone is 9005 and so was the firmware for it.
I am done with my research and yes I came with a big F in my certificate. I am exhausted, disgusted and utterly pissed! With that said, here is what happened, what I did to solve it and what was the aftermath.
What happened?
I got a Samsung Galaxy Note 3 SM-N900 as a gift from my friend. He purchased it from United States. As you can expect, I wasn't aware of this popular issue for Galaxy Note 3 because I didn't plan on purchasing it. If I would, I would have done my research. The phone, as beautiful as it was, arrived in its perfect state and worked like charm with one of the Bangladesh carriers (I used Grameenphone just in case any of you were curious).
Things were working great until I had to go to US myself. I had a transit in Saudi Arabia for about 12 hours. In the meantime, I purchased on of their local SIM card and stuffed inside Galaxy Note 3 (stop biting your nails. I know I screwed up). It worked like charm too. Arrived in US. Purchased a T-Mobile SIM card and surprisingly it worked great with that one too.
Things changed when I came back to Bangladesh though. Now that I am in my home country, the baby doesn't recognize its mother anymore. Not even a single carrier's SIM card gets detected inside NOTE 3. Instead there is a "X" sign on the top of the SIM card icon. To make it worse, the IMEI number is also gone. I know you wouldn't believe but I didn't go through any flashing process whatsoever. The only thing happened is I changed my location geographically. Since then, I never got it working. I never actually tried to get it working as I had so many phones in my stock.
But things changed. With time, my primary and secondary phones disappeared and I am only left with my Galaxy Note 3 (the last one got stolen). As a last resort, I tried everything but failed. According to the popular issues in internet, my phone doesn't ask for any sort of codes whatsoever. I am actually never greeted with that screen. The problem I have is, no matter which SIM I put in, it never detects. Any network related number execution obviously returns with "Not registered under network" (codes like *#06#). Tried the Region unlock away app by Chainfire and also didn't work. Tried tonnes of custom ROMs that didn't solve either. Right now before posting this question, I am downloading the stock 5.0 firmware from SamMobile for Bangladesh carriers. I hope it works but it will be my final try. After that, I live that upon you experts. Can you suggest what to do?
The actual problem
1) No SIM card is detected.
2) IMEI and IMEI SV says Unknown
3) Also a nifty info is after I used the Region Lock Away, it said the process failed because it "couldn't locate CSC data! You could try flashing a CSC package to correct this"
4) Just if you are curious, yes of course my device is rooted and currently running Lineage OS.
Thanks in advance.
2) IMEI and IMEI SV says Unknown
RESTORE your backed up EFS folder .

Now would you call it a self destruct if I said I don't have anything backed up? The IMEI disappeared when I arrived in Bangladesh and turned the phone on with the local carrier.
There has to be some way to get the SIM working, right?
Self destruct if you mean fail to read the basics then yes.
Suggest search IMEI problem amongst theo thousands of posts one or two succeeded .
