Hello!
I'm having signal problems with my phone. I've tested the antenna on another phone and it works flawlessly. The usb module is brand new and the faulty one I replaced already gave me the same signal problems. So, before I panic and start thinking in replacing the motherboard, I'd like to exclude any possibility of this signal problem being on the software side.
I'd like to test using the phone with everything stock. I know I have a SM-N9005 but I don't have access to either the IMEI nor the S/N (error while dialing *#06# and I don't have the box nor the sticker on the back of the phone).
The first thing I would try is to flash the phone with Kies. If that does not work, download your firmware from sammobile.com and flash the phone with Odin.

I did it via odin but phone doesn't boot unless I flash TWRP and install some custom rom...
I made it to boot with some 4.4.2 stock rom but it doesn't get past the startup (it crashes when I get the prompt to name my phone).

The only reason this sticker would be missing is if the phone was stolen, there is no other reason to remove the sticker.
Is there?

I don't know about this phone's past, I didn't buy it new. But I managed to get the S/N and register it in the Samsung site, and IMEI isn't locked.
Well, I managed to flash things throught Odin, thanks you all

Hi everyone. I know this problem is well known, and Ive done hours and hours of search online and on XDA but none of the solutions worked or maybe i didnt do it right!
The problem, My friend have flashed a Custom frimware (Litning 6) and lost his IMEI and Baseband some how, they tell Unknown, and now he cant access his SIM or network, the phone doesnt really see the SIM at all.
Ive tried to use Chainfires APK to fix it didnt work, and the Hex stuff really made me dizzy out. didnt know how to use it really.
Ive tried to recover to EFS stuff but i think his EFS is trashed and he didnt back it up..
Tried flashing 2.3.3 stock rom and 2.3.4 no luck. still no baseband or IMEI..
Any suggestions? im out of luck and depressed
Why are you out of luck and depressed if its your friends phone?
If you dont know and understand how to recover these details I would say flash to a stock rom and take phone into a SSC and let them repair it for you.
Same thing happened to me, the phone eventually showed firmware emergency error so I just gave it to samsung service centre, they replaced the logic board etc and got it back 3 weeks later

ill look those links,,, but can i use someones EFS folder to fix this?
Ive checked the links. i think noth bin and .bak files are bad. cuz he already tried messin with them.. XD need new nv_data
you said that he LOST his IMEI.If thats true,and by using a root explorer with root access you can look inside the efs file or mark *#06# and see if nothing comes up,then without a backup theres no way you will get the original back without sending it away to the service centre(personal experience) but when it come back heres a good backup method.Easy as to backup and restore.

Basicly his SGS2 is not even capable of bring a paper weight cuz its too light (100g) lool.. what a bummer... ill try to find a shop to fix it with a box or something,, thanks all!
If you check your nvdata.bin and md5 you will see that, they modified the same day you lost your imei. So you have to return back to those baks and I don't think you can use another device's efs since your imei is hidden in that file.

-Fix Repair unknown base banad I9100
Note 1:
we add 3 Solution for this problem after you click Repair unknown baseband and select i9100,procedure start after finishing Solution 1 and phone restart check imei (with *#06#) if solution work you must see your phone imei if you see that you can cLick cancel and enjoy your revived phone if not click on continue and wait until solution 2 finished
do same like after solution 1 (*#06#) work on phone if you get good answer click cancel if not continue for starting last solution if it's not work too,believe me fellas check for hardware fault
Somehow this has happened to my phone, it is not even rooted, I flashed a newer firmware because I'm with bell mobility and they are still on 2.3.3, but that was over a month ago and just yesterday my phone stopped reading my sim card, and the IMEI and baseband are unknown.. I've tried a factory reset and to reflash the firmware, but it is still not working..
Now I cannot find the stock bell mobility firmware either to send it back..
has anyone figured out how to fix this problem? Or what could have caused it in my case?
looks like the service centre is the only option. Best to back up the EFS before tinkering with anything.
my GT-I9100 does this when I let it completely run out of battery power. I've only noticed it since flashing the ICS leaks but this may have been a problem before and I've not noticed.
When I plug the phone into the charger and start it up *#06# IMEI shows as unknown and *#1234# shows unknown modem, I have a small airplane mode symbol and occasionally, a no sim card error.
To fix this I have to let it take a charge for a while with the phone on - then reboot WITHOUT the charger cable plugged in. I probably have some kind of hardware fault but its not that important to me. I have an EFS backup, well I have a few backups here and there
happened to me a few days ago

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.
solve problem
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

Had the same problem like you before. You must have done something that altered the Baseband/Modem. I will assume you haven't made an EFS Backup. What you can do is this, download a stock Firmware and manually flash is. Just be sure that the firmware you will download is meant for your country. After flashing, try to see the IMEI of your phone. If the correct IMEI shows, then try making calls, text and connect to your mobile data. If not, then try flashing any modem meant for GT-i9500. If the problem still persist, then your last option would be to change baseband antennae or worst, replace the board itself which can only be done by technicians which has the proper replacement parts.
Thanks for answering, i flash my device with my country oficial stock room, after that im still having the correct imei but cant make calls, say no service and no registered on network, i have efs backup, but after restore nothing happend =(

Problem:Rooted the phone and due to some issues but somehow it became unrooted so I tried to root again but this time it failed during odin downloading mode halfway. so I unplug and was not able to boot up the phone. So i download and install the stock firmware from sammobile and manage to get the phone to startup . But the next issue is that the imei is gone and serial number's wrong with no network .
Did a bit of researched and I managed to write my own imei in through a thread I've found here . But my serial number is still different from what I've checked from the back of my phone and the network is still not up . I've check my ESN n MEID number is some random numbers or just 000000000 , tried to search for how to recover but to no avail.
I've tried doing imei repairs using GSII_repair and tried to follow some threads on things like deleting efs folders etc BUT I am not able to find the nv_data file even after rooting so decided to drop the method .
Do let me know what you guys need in order to troubleshoot the problem .
Did the phone's imei and serial # match the label before you rooted the first time?

Erm , I'm not sure about that thou . :crying:
Did you buy the phone new or used?
The easiest way to fix that, is to flash stock rom, but not just any ... it has to be the exact same region as the phone originated. Otherwise you get screwed EMEI, etc. Some countries the phone is carrier locked, so you also need to take that in account when getting stock rom. If you can't find those out... then it can be a problem. Maybe bring it into a samsung repair center to be checked out.

I flashed the stock rom from sammobile using odin , managed to get the phone up but thats when the imei and sn gets screwed up I think . I'm from singapore and our phones here are all unlocked . Used to work for 1 of the telcos here so I'm 100% sure it's not sim locked . I checked with my friends at samsung and they told me their process is to switch the motherboard and it's not worth the price, so I would want to try all the methods first before converting it as a expensive media player lol.
So the phone is originally from Singapore? Or you just flashed stock rom from Singapore? If the phone is originally from Singapore and you flashed a stock rom from Singapore, it should work... unless you tried changing the EMEI yourself. I think it's all messed up now, so you probably only have to take it to a shop that can do that for you. Changing motherboard from Samsung (or any manufacturer) is always super expensive. Hopefully you can find someone else with a small shop that can do it -- otherwise, I guess better to get something else (because price won't be worth it, as you say).
Good luck. Hope you sort it out.
PS, I like visiting Singapore sometimes... miss Brazil Churrascaria ^^.
Yeah yeah I know, why didn't I keep the sticker on the back of the phone?
Hindsight's a wonderful thing, looking back!
I appear to have bricked my device. I have the exclamation mark in a triangle, with the following message:
"An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software"
I have the box which the phone came in so have the IMEI number, but need the serial number to use on Smart Switch.
Phone is SM-G935F model, which was running TEKXnesis rom, rooted. I was attempting to reinstall stock firmware, as I was having issues with the phone (Rom is excellent I hasten to add), and that's when the problem arose.
I can't boot into download or recovery (TWRP 3.0.2.0 was installed).
I have Googled but have drawn a blank, so any ideas would be most helpful.
Thanks

There's a small letter that show serial number (s/n) along with your imei in the lower part on the back of the phone under the glass.

Cheers, never knew that, but under the light of my trusty S3 torch it's clearly visible.
Have managed to get my S7 Edge back by flashing TWRP via Odin directly to the phone without being able to get into download mode.
Thanks again

Does the SN the on the G930U start with A3? I am in the same situation you were in and neither that or the IMEI is working. Any thoughts?

I'm in the same situation but the problem is that i replaced the back on my phone a while back so any where else we can find the serial number

No joke, this happened to me on Thursday as well. I was in the same boat as I took off the sticker and it's nowhere to be found on the box. What I did was I went to Samsung customer service live chat and gave them my imei and they gave me my serial. Then I was able to use kies3 and flash stock back again. I seriously thought I had completely screwed my phone and have to shell out 80 bucks for a repair shop to do it. Hope this helps as it worked for me. Good luck!

So you were able to talk to Samsung through live chat and they gave it to you from IMEI?
Which site and chat did you use if you don't mind? I did a mobo swap and only have a software S/N in settings.
hey everyone a bit of a different problem my Samsung S6 Galaxy Edge Plus was stolen and I file the police report and I asked for the serial number however I don't have it and I recently changed over to Tmobile so I can't look into my Verizon account and see if they have the serial number I'm about to check TMobile account but I don't remember seeing it on there previously is there any way else to find out what the serial number of your phone is it is still under my possession because I had purchased it right before it was stolen
For all those whom have lost your imei or serial number on your S7 if you dont have the box or the backing has been replaced,
If you remove the backing to the phone there is actually a sticker on the battery with a gold tab at the bottom of the phone that contains your imei number and also serial number.
Samsungs print the imei number on the devices 4 times 1st in ☆#06# 2nd is lasered onto the backing at the bottom 3rd is the sticker atached to the backing when first purchased & 4th is the sticker under the backing of the phone located on the battery at the bottom,
If you have lost your imei & not serial number also and cannot retreive it with stock firmware installation then use Z3X 29.8 cracked with the loader open the Z3x tool go to repair enter the imei printed on the sticker and click the repair button your phone will restart and your imei will be back you must have your phone rooted for Z3x to work however i have tested this repair on android 6.0,7.0 & 8.0 with Z3x cracked it changes the imei every time,
Dont try to change the imei to another different not matched to your phone and patch certificate as it will not work patch certificate only works in 6.0 if you change it to another go to ☆#0011# you will see at the bottom the imei say NG when it should say ok so domt change the imei and try to patch cert you can also set the sim count to 2 with 2 imei numbers also on the G930F to make it a dual sim as i have inspected plenty of G930F board and they all have printed on them G930F/G930FD/G930W8 i have also inspected the sim slots and they do indeed have the pins required already built in to the reader the only thing that is needed to change to dual sim is the dual sim card sim slot and set 2 imei number in the box and set sim count to 2 and voila z3x does the rest. Pls note though you cannot change the serial number on them with z3x thus serial number is what linked to the modem HW ID to allow the phone onto the carrier networks the best ive been able to do with android 7.0 & 8.0 on the V2 firmware is change the imei and when putting a sim card in getting the option for VOLTE however wont register on network and imei is still NG instead of OK in ☆#0011#
Anyway enough ranting of mine hope this can help someone and apologies for reply to an old thread guys im really baked and really bored buisness is slow today haha sunday in australia...... trying to figure out FRP removal on G930F V2 bootloaders also turns out if you extract the firmware with winrar then extract the AP file with 7zip then go to meta data inside that is a file called FOTA.zip well samsung have added there very own password to protect such file on the archive took a while but fotatest1234 isnt a very secure password samsung once extracted enter and find the build.prop enter that and theres all the information to edit the settings to enable ADB by default ive done that packed it all back up but just cant get it to flash ive used .imgTO.tar to convert the file to an MD5 that odin will accept and i get the message leave CS... which means odin has loaded the file and has found no error in the binary but as soon as i hit start odin will crash mabe it has something to do with odin and the edited build.prop or the way im packing the firmware back up anyone know what im doing wrong ? Any help greatly appreciated while im here
