hi Dr. Ketan and others,
I am facing signal, network registration, out of service etc issues, i tried everything updating/downgrading modem,BL, roms, even replacing qcn but nothing helped. After replacing qcn it did worked but for only one call then again no signals, cannot register network etc. I didn't gave up on repairing it. I kept digging and found!!!! that when in hidden menu i click "SW WATCHDOG" once my phone works 100% but only for some second 20-30 seconds after that it again goes back where it was before. I want to know what the problem might be. How can we permanently enable "SW WATCHDOG" i know we can enable it in note 2 but those coded won't work in note 4.
Oh BTW my phone model is n910f from greece.
opinions from other member are welcome.

My i9500 has driven my crazy since yesterday, I even stayed up all night trying to find a way to restoring its IMEI. So here's the problem:
I was playing a game called "Friendly Fire" and decided to turn off its notifications using Application Manager. Everything was fine until a few hours later when I opened up my phone and saw the mobile signal was gone, only a circle with the diagonal dash inside it left. At that time I thought it was fine but then suddenly it popped up the message "Please enter SIM card unlock number" or sth like that, which was an error indeed because my i9500 is an unlocked version. I though it was the mobile network who locked the SIM, but when I tried putting the SIM into other phones, they all worked! And so I started to find a way to unlock my i9500 by ServiceMode Menu but I could never reach the ServiceMode Menu, it only showed a blank screen. I checked my IMEI and it now said "null/null". I had never rooted or flashed any ROM on it so it was really really strange. So I reached a topic on "how to solve the null/null IMEI" on i9500 because it seemed that many people got this problem. However, nothing helped I even rooted my phone to see whether I can back up then restore the 'efs' folder. Well, I did manage to do so but the IMEI would not change at all. The strange thing is that when the phone was just booted up, if I enter *#06# the IMEI shows "null/null", but if I enter *#1234# first then *#06# it shows the generic IMEI (0049...), which was useless as well. I tried different methods, flashing to different official stock rom, but nothing worked. Also, when I flashed an official stock rom, Kies did not show the right region of the firmware but "XXX" for every firmware I tried. And of course, my mobile signal was lost so I could not make any call/text/3G/LTE/etc., but the rest (wifi, bluetooth, gaming, etc.) was okay, it is basically an ipod touch right now
I wonder if anyone can help me with my problem? I know my real IMEI number (at the back of the phone) and that's it. I bought it from another country so it would not be possible for me to bring it to the Samsung store where I got it from. I could not remember the country where its first firmware came from Is there any way to find out that?
Many thanks for reading my trouble :crying:
Well this weird, I am wondering if an android virus could do that....

I bought it in the U.S. in July, from an official Samsung store. Well, the box containing the phone and the phone itself were "made in China", I thought most products have those words? It would be ridiculous if that is the problem because it also has a line like "Korean product"...
I wonder if Octopusbox or SPTbox may fix the problem? I don't know those two things very well though.
I had the same problem on a different samsung phone (Note 2) and i was getting imei 0049 or something like that, Basically my imei had changed or gone. The issue i found out to be a baseband issue so what i had done was downloaded a few compatible basebands and flashed them via odin and eventually got my imei back. There is also this link for you to have a look at http://forum.cyanogenmod.com/topic/77400-booting-issues-and-imei-loose/ just in case it helps. Hope you get sorted.

According to your description， you can have a try resert your Samsung galaxy s 4 and then restart it to see weather it is OK? If it still not fine, send it to Samsung After-sales service
Yesterdag I received a Samsung Galaxy S4 I9500 from a friend.
He said the phone came from India, but he was sure he was unlocked.
After putting in the SIM card, the phone did nothing, it didn't recognize the SIM and didn't even ask for a PIN Code.
So I thought that he was locked, I wanted to use *#0011# to go in ServiceMode and unlock the phone. But after going into the ServiceMode, it didn't show any options at all. It was just a screen with ServiceMode on top.
I know there are other codes to come in ServiceMode but even these wouldn't work.
After that, I did *#06#, and a little popup came on the screen with "IMEI null/null"
I found the fix on the internet for this, but even this was without succes.
I tried several other roms and modems, but that didn't give me any progress.
Does anyone has an idea how to fix this? I really don't know what to do anymore.
The phone is brand new. Nothing has happened with it.
Thanks in advance!
Flash one STOCK ROM in Download Mode using Odin 3.09
*EDIT: If after these steps the imei still null/null then the problem is hardware. U will have to let ur phone in SAT (Technical Service Assistant)
I find that almost impossible to believe. In my experience with the Galaxy series of phones over the past couple of yrs, IMEI's do not disappear for no reason all by themselves without anything being done to the phone. 'Your friend' has left out a bunch of information here.

Hello, thanks for the fast reply.
I don't think so, he unboxed it, tried a sim card. After he saw the sim wasn't read at all.
He gave the phone to me ..
He came straight out of the box without a IMEI number in the phone.
Hey guys,
I know this is a fairly "common" question but im a bit stuck.
I just bought my N9005 (second hand) and it cant get any cell reception. 4G, 3G and Edge are all working perfectly but I can not make calls. When ever I try to make a call it says "No mobile network available"
If I go to Settings and choose a network, a notification will pop up saying "No service" and below "Selected netwrok (BASE) unavailable".
Now I flashed CM11 and factory reset the phone but now when I choose a mobile network, it will endlessly say Registering on Base.
Eventually it registers but gives me the same error as mentioned above.
I have checked if the IMEI is set to null like it seems to be the case on some phones but its not and after checking the IMEI it isnt blacklisted either.
I found some file called "WriteIMEI.zip" on the phone if that is any indication to what is going on with this phone?
Please refrain from all the comments about paying more attention when buying phones, im looking for help please.
Thank you.
EDIT: I found this on google, I dont know what it means but maybe someone could elaborate
N9005 AND N900w8 are Similer You can Reset EFS and repair IMEI and 3g Network for N9005 in N900w8

1. Backup efs,fsc,fsg partitions using efsbackup (thread in forum).
2. Do not ever flash anything before doing step 1.
3. Ask seller what this writeimei.zip is about.
4. Post his answer here
5. (Optionally - do step 1 to 4 before flashing) flash back to stock. If the phone was originally bought you most likely need the Luxemburg rom.
Hello!
I have a Galaxy Note 3 SM-N900 that I got from a friend. When my friend gave it to me he still had all his stuff on it so I did a factory reset on the phone. After I reset it the phone had a null IMEI and an unknown baseband. I'm pretty sure the problem is with the modem as I've flashed the stock firmware on the phone several times, I've tried almost all the custom roms on the phone, I've even flashed a whole boatload of different modems.
One of the times I was at school I pulled out my phone to change my music and I noticed it had signal. The phone had signal in different parts of the school and it also had a working IMEI and a baseband. I called 911 to test if the phone worked and the call went through as if the phone never had an issue to begin with. I haven't been able to get any signal on the phone since then. I don't know what else to do and I was hoping someone could help me here! Thanks in advance for those who try to help me!
IMEI Standard answer is to restore your backed up EFS folder as per the faqs and guides .
You may well have a lose connection/ sim within the phone if its intermittent on .
Sadly I don't have a backup of my EFS. I had reset my phone from the settings menu so I didn't think that would cause any problems. Is there anyway I can get a backup of an EFS for the sm-n900 or are there any other solutions?
Is there anyway I can get a backup of an EFS for the sm-n90
NO
You could try flashing a stock lollipop firmware .
Again, I've tried that multiple times already. My EFS folder should be fine if I got signal randomly. My sim contact isn't loose as when I got signal I didn't have a sim in the phone. I think the problem is my modem but if it is I don't even know which modem to use.
Modem for your location/ network .
How do I find the correct modem? I live in the US and my network is MetroPCS
Also, thank you for trying to help me. I honestly appreciate it.
Please help me anyone!
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.
