My samsung galaxy s5 g900t started having problem this morning. I;ve been using blisspop rom since 3 month ago and everything was fine. But now my phone wont even find a signal. The signal bar is empty. I though it might have been because of an app. therefore i deleted any unusual app, and nothing happened. Then i proceeded to factory reset and nothing happened, then i decided to change the rom, and nothing happened ( i changed to 6 different roms, all between LP and MM. I proceeded to flash the stock firmware via odin, it successfully flashed the stock firmware, However nothing happened. It has an empty signal bar with and x on the inside. So far I've tried with different sim cards and it happens the same. NOTHING. My phone has been using heavy duty covers since day 1. The last cover i bought was the Love Mei one. Which is Extremely heavy duty. (combination between aluminum and rubber).However im starting to think that i will have to buy a new part of the phone. I know about phones, and software related, however i dont know as much as a professional or amateur would about hardware (external)
Can someone please give me suggestions about what to do before proceeding to buy a new part? If i have to buy a new part, which one do i have to buy? the antenna? or what? I've posted the picture of the screenshot ( look at the signal bar) Forgive me if someone has posted the same issue, however the suggestions xda was telling me are far from being the same than my problem.
Do you still have an IMEI if you type *#06# ?
If not, I hope you backed up your EFS partition before flashing ROMs

No. I didnt. Okay i though it was a lost cause. Here is what happened, somehow my EFS folder got erased, and my imei and S/N were gone along with it. After you lost those 2 essential things every company turns their back on you. So, it is either you fix it by buying one of those boxes that fix imeis and networks related, or buy a new logical board on ebay; or just give up and proceed to buy a new phone. However, even though i saw that my imei was null, and my S/N was also gone, Having no backups of EFS, I was at the edge of giving up. Until i decided to do the following: I installed the firmware that came with the phone. which it was a 4.4.2 version. Then i upgraded it to 5.0. And..... Everything was back... however my IMEI is not the same that came with the phone. Which is kind of odd. How did i get a new IMEI by just goning back and for between upgrades? Who knows.... Anyway, now I have full bar as its supposed to be. And currently 4g. (There was another thing i did but i will refrain from telling, since it isnt that interesting)
Very strange, but good news it's working
I'd would strongly advise you to back up that EFS partition asap now just in case

Ueah. I never thought that would happen to me. Thats why i never did the backup. I did it as soon as i saw that i got signal, service, imei and sn back. Haha
No-one ever thinks it will happen to them, that's why I backed mine up before I even decided to flash anything custom at 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.

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
http://forum.xda-developers.com/showthread.php?t=1526733
I bought the N910F a few weeks ago. I'm traveling so I had it unlocked in Bangkok to use other Sim cards. That's when my problems began.
They rooted the phone and changed my IMEI number. The result is: Knox flag tripped, fingerprint sensor not working anymore (error), losing WiFi passwords (had to do ro.securestorage.support=false to fix it) and worst of all lag and bad battery life. I can't even watch a HD movie without lag. AnTuTu score 36000.
The efs folder is empty (not mounted). I have no backup of the folder. The phone functionality works fine. I got no problems with any Sim card. I have a valid imei, just the wrong one. I tried firmware installation and initialization with Kies, but it didn't change anything.
I'm traveling through Asia for many months so I can not get a replacement or send it in for repair at home in Europe.
Do you have an idea how I could get my original imei back? or how to mitigate the issues?
I had a very similar problem, I thought I was sunk. But then I found THIS post, I used the Edit 2 method and it worked a treat, hope you have similar luck. If you don't have TWRP, then I'd recommend you install it, can be a real lifesaver.
thanks for the link. it worked partially. I managed to mount the efs folder. the partition for n910f is mmcblk0p13! I used the terminal emulator on my rooted phone with busybox. no need to use recovery.
the bad thing thing is, I still don't have my original imei. the good thing is, my fingerprint sensor works again, I don't need the Wi-Fi fix with ro.securestorage. support=false and the phone feels much faster, less laggy now.
kinda happy with that. If I had the efs backup now....
would a initialization with Kies restore my original imei?
Sorry, I really can't say, I've never used Kies. Glad it seems to be running better now.
Should have mentioned the partition on a N910 is /dev/block/mmcblk0p13, getting old and forgetful, LOL.
That's a bummer OP - a non-factory unlock on newer Samsung phones involves writing another phone's hacked EFS data.
If the store didn't do a backup of your old modem data, your original IMEI is gone.
DO NOT attempt to use Qualcomm NV Tools to change your IMEI back to stock. (Guess how I wrecked my Note 3 the first time around!) - you need a valid IMEI Certificate to access 3G/LTE networks so you'll be stuck in 2G mode.
Samsung service centers have the tools to write any IMEI they want and generate the valid certificate, though it'll be expensive. I'd just advise OP to Odin to stock and wipe data, then root and disable ro.securestorage.support.
Having a wrong IMEI's not too bad, although a big no-no in terms of the GSM standard.
1) I think I have a valid certificate for my 'new' imei. Mobile data connections work fine and fast (H+). I prefer my original imei though.
2)why should I disable securestorage.support? It works fine enabled.

As part of the unlocking process, they wrote a new (rather, copied from another phone) IMEI to your Note 4. It'll work just fine. However, the IMEI may be shared with other phones, and may one day be blacklisted. When/If that happens, you'll need to write a new IMEI again.
I think I didn't come across right the last time - don't try to change your IMEI to your original one with Qualcomm NV Tools without a matching, proper certificate for it. It's a world of hurt.
As for ro.securestorage.support, it _might_ be needed for keeping WiFi passwords saved on reboot. Or not. IIRC, my rooted Note 3 needed it set for WiFi and S-Health to work right. I'm staying unrooted on my Note 4, so I don't know if you'll still have to do that.
I will go to a service center and ask if they can restore my imei but it doesn't seem to be urgent now. I just hope that a kies install of lollipop doesn't bring back the problems (unmounted efs).
WiFi passwords survive a reboot without the fix. So far so good.
Thanks for your help.

Dear all,
I am writing here as a last resort. I have an S5 G900F european model, I have rooted and flashed custom firmware without problems. I've been messing with samsung devices since the S2, so I know a bit about rooting and stuff. Funnily enough after rooting and flashing custom firmware, I noticed receiption getting worse by the day. I ended up with very minimal to no reception at all inside, and outside slightly better.
I am on Vodafone 4g, and getting not registered to network in worst cases even if reception looks full. I've tried original firmwares, reflashing modems, various CSC's but nothing worked, not even changing the SIM.
My warranty is void, so what can I do ? Can this be a hardware problem ? Nothing is working. PIT file is only for repartitioning, and I have no problems with that, so didn't try PIT Files. Csc as I said, i've changed them but with no luck, along with various modems.
Any help ? Please!
Thanks!
Did you make a full Nandroid backup of the original ROM before flashing custom?
I believe the EFS partition on the phone contains pretty important things such as IMEI and radio files/data
If that got messed up, it could be the cause of your problems
Hopefully you made a backup of that, and can try restoring that partition
IMEI Number is still present.
I have no back up unfortunately. That's a mistake. But how can I fix it ? The IMEI Number is still present and it's the correct one according to the sticker, so that's ok.
How can I fix the rest?

If it is the EFS partition and you don't have a backup, I'm not sure
I have read some people saying they have backed up one S5 EFS, and restored it to another successfully, but I don't know the consequences of doing that, I would imagine it would cause problems having two identical devices on the same network, like two identical IPs conflict on the same network, but I'm just guessing - possible if the operator blocks one S5, it would block both
I'd make a backup of it anyway

---------------
I have flashed various modems, with no luck. I noticed my IMEI matches the one under the battery but as a /01 at the end. Is it corrupt ? Can I fix it ? Probably that's causing the issue. I've heard /01 is fake or corrupt IMEI.
Mine has a /01 at the end of the *#06# IMEI too, and mines not corrupt or fake
Doesn't sound like the IMEI side of things is the problem, but possibly the radio side
Like I say though, I don't know much about the EFS partition, only that it contains very important data for the phone to work correctly
Definitely back it up before trying to fix it further
I have backed it a few days ago to be super sure not to do further damage. I'm just very confused. The reception goes up decently in certain areas and very low in others. Definitely goes completely down or no network when inside. It's like the antenna in not connected correctly like it happened to me once with my SGS 4 when I dismantled it and forgot the wire connecting the antenna.
But in the case the mobile is only a week old...never opened. I'm guessing i messed up as I noticed these signal problems only a day after flashing the mobile. Could it be something else ? I've tried PIT files, new firmware, clearing the NAND and EFS with Odin, and still the same problem. Even Kies firmware recovery. Nothing helped and dozens of firmwares and modems.
I'm stuck

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 ^^.
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.
