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

restore efs backup and flash last 4.3 stock room by odin

Hello, I've had my s5 for a while on a Vodafone contract with no problems. The phone was rooted and had a custom recovery. I recently got it unlocked from a local shop due to moving contracts and now since then the phone will not connect to a single network. I have tried 3 different sims from different networks and all the same result. I flashed to stock again and no help. My device status reads:
Network: unknown
Mobile Network type: unknown
Service state: out of service
Mobile network state: disconnected
Phone number and IMEI are correct.
Dialling *#06* shows my correct IMEI. I can't get into any service menus due to no root now, and my EFS folder appears empty
Any help will be useful, thank you
Was root broken by the unlock? A SIM unlock shouldn't break root. First try wiping your system cache from recovery mode. If the problem persists, then your best bet would be to restore your backup which will certainly resolve your issue and let you proceed from a stable position. If you don't have a backup, what the hell? Why wouldn't you be making backups?
As (a much less desirable) alternative, make a backup at this point or at least save any important files or photos. Then temporarily install a 100% stock ROM followed by a factory data reset. This is to rule out software issues other than EFS. If your phone now works, then it was a matter of a broken root or conflicting settings.
If you still have problems, then you need to provide a lot more information if you want good advice. We can't see your handset so if you don't give us a lot of details all anyone can do is flail around in the dark and make guesses. Try your SIM card in another unlocked phone to confirm that it still works. Confirm that you wiped your system cache and tried a factory data reset. And tell us step by step what you've tried so far.

Thanks for the reply, I will describe as best I can what is happening:
Firstly as the phone rebooted from the unlock I could not register to any networks. Root was still there and TWRP also . I restarted the device, and nothing happened. So next I tried a different aim and still I have no network. Both aims work in another phone. I did what you mentioned next and restored a backup and still no fix.
I tried factory resetting and wiping the cache and again, no fix. Then I flashed the stock firmware through ODIN which had no effect either.
If I use the sim in another handset then return to my s5 with it on first boot up it registers to EE and pulls a signal with no Internet, then quickly unregisters to emergency calls only.
Thank you for your help, I will give any info about the device that you need.

Hello community, I searched for hours before actually posting this thread.
My device: Canadian SM-G900W8(klte)
Last stock firmware: G900W8VLU1BOC1
Carrier: Rogers
Recovery: TWRP 2.8.7.0
Two days ago, I flashed the CyanogenMod 2015-07-14 nightly build on my phone using the official guides including gapps and everything seemed to work perfectly except one thing: the phone can't connect to the cellular data service but calling and texting does work, only internet dosen't it won't connect to the 3G/4G/LTE at all.
Before flashing I of course backed up everything with TWRP including my EFS/MODEM partitions so I switched back to my stock nandroid backup because I really needed my fully working phone the next day and it was late and data worked again.
Today I gave it another shot with the 2015-07-16 nightly and the same problem is there... I verified my APN settings and everything is correct. When I first got into the APN menu there were alot of them on the list including the ones I had on my stock ROM but none was selected so I ticked the one I had before but it still dosent work, I tried all of them on the list and no result. I even verified the APN(s) exact settings with my Carrier and everything was good yet the phone still won't connect to LTE, but calls and text do work again... Another thing I did was to restore the modem/efs partition with TWRP while running cyanogen just to be sure but it didint have any effect.
I really wanna use CM because I'm disgusted and tired of TouchWiz but I'm clueless on how to make the data work I tried everything I knew and read on forums.
I have the exact same issue...same phone, same network....
Did you resolve this?

Try to delete All Useless APN setting. It resolve my problem, and I have the almost the same configuration. ( Rogers, S5, Cyanogenmod 2015-08-01 )
The only one problem that i got, sometime LTE network lost signal for 10-30 seconds. But for what I read, it a common issue with this version ( 5.1.1 )
Good Luck !
Tried all that....
Finally went to an earlier build from April....working good now!

Thanks for the suggestion. That fixed it for me, as well. I actually deleted all the APN settings and then recreated Rogers LTE (ltemobile.apn).

This also fixed my phone
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
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.
A few days I woke up with no service on the Nexus 6p. This was a few days after updating to the latest oreo build. Sim card seems detected because when I take it out another message shows up "No SIM card - No service", and when I put it back it only shows "No service". Tried putting the card in a Nexus 5X and it works fine.
Tried the following with nothing working so far:
- Switching 2G/3G/LTE and rebooting in between.
- *#*#4636#*#* and turning off the radio, switching between the different options of GSM/LTE/etc...
- Restoring a working nandroid backup
- Reflashing different ROMs
- Factory reset
- Factory reset then flashing ROMs
- Wiping cache and dalvik
- efs fix in twrp
Hardware version ANGLER-VN2
IMEI shows up under IMEI information tab but not under SIM Status tab, there it shows not available.
I live in Ontario Canada, carrier is Freedom mobile.
So now I'm stuck, tried calling google and hwawei and they won't do an RMA because my warranty is expired.
Anyone has any ideas to try?
Thanks in advance.
Not that this is going to help, but this has GOT to be an Oreo issue, myself as well as at least 4 others that I have seen has been getting the No service, or No Sim, mine did the No Sim, then started bootlooping.

No this has nothing to do with O.
Which version phone do you have? H1511 or H1512?
What country are you in now?
What is your carrier? If MVNO state that.
Are your IMEI and phone numbers showing up in settings?
Everyone, please put the most basic information in your profile like where you live, which carrier you are currently on, and maybe even which variant of your phone.
I updated the first post with more info. How do I tell if I have H1511 or H1512? I bought it from the google store in Canada.
More information is good. Please update your XDA profile so the next person trying to help can check there first. You can find the device variant by booting to bootloader (not recovery) and using the vol toggle to navigate to "Barcodes". IMEI should show up there too. Date of manufacture, Serial #, etc. I think you should have started a normal thead, not Q/A, BUT your IMEI and a lot of other information should be showing up under SIM info. That's a problem. Second, you say you did the EFS fix in TWRP. Can you explain how you did this? Did you use one of YOUR OWN TWRP backups which contained the modemst1,modemst2 and restored ONLY those two partitions to your device? Did you receive any confirmation or error? Have you tried using a SIM from a Rogers or Telus in your phone to see if the SIM info shows up?
Thanks for the help, I'll update my profile with this info as well.
in the bootloader the IMEI shows up along with the rest of the info. It's a H1511 device.
The EFS fix is by following this: https://www.theandroidsoul.com/fix-empty-imei-corrupted-efs-no-sim-unknown-baseband-wifibluetooth-issues-restoring-twrp-backup/
is modemst1 and 2 contained in the twrp backup? and if so how do I restore it? in restore options there's system, data, vendor and boot only. I guess it's an option in the backup that I haven't selected?
I tried another SIM also from freedom and it didn't work. I don't have a Rogers or other SIM to try currently.
Right, so if you didn't ever select the EFS partitions when using TWRP Backup, you never backed them up so under Restore they don't show up (so you can't use that method). You can however use TWRP terminal or fastboot to wipe those and reboot. I would be sure to try at least one SIM from either Rogers or Telus. If that doesn't work, then wipe the EFS partitions and let them rebuild (hopefully).
Definitely Oreo issue. Google messed with something and it broke data for many people. I have been troubleshooting this for the last week (Verizon, US, fully stock 6P) and finally found a thread where a Google rep acknowledged the problem and said it was high priority for a fix.
I wish you luck with that one @LucJoe. This has been happening for the past 2 years from MM, N, and now O...and XDA is full of threads (just look). So you just go ahead and wait for Google to fix it for you, LOL. - Not a new issue related to O.
Never happened to me before updating. The data issues manifest differently across different carriers but for some reason Oreo likes to play it safe and disconnect data. I have not been able to get LTE for more than a couple seconds, but will get slow unstable 3G occasionally. Google confirmed the issue here: https://productforums.google.com/forum/#!msg/phone-by-google/kw3ZcXd1BVs/7HYuANdoAgAJ
A recent success using terminal from TWRP (or the OS if you are rooted). You can also use fastboot to do the same thing using the commands in the article posted in this Q/A (method 2). Good luck! See thread here.
This seems like it's a different issue described in that thread. I'm not running out of data, there's no service and no connection of at all to any network.
I did find that and try it before posting here. It did nothing to fix the problem. It did say that something was copied over '4 MB copied, at 14.3 MB/s' something like that but nothing changed.
I also have the same issue. Have tried everything including going back to stock 7.1.2 & locking the bootloader. Nothing seems to work. Interestingly, when i pull up the hidden phone diagnostic menu, it shows all cell measurement info which means that the antenna is receiving signals but the phone somehow is not registered on the network?
I can wipe those partitions with fastboot but is it safe? I have never used TWRP and my problems started after updating to Oreo. Is there a chance the official OTA could corrupt those partitions?
@LucJoe- That fix is not for you. That is for users who have no IMEI or phone number under About Phone>>SIM info. Your issue (as I understand it) is a weak and intermittent signal that keeps disconnecting LTE and sounds like a carrier or SIM issue. Why not go get a new SIM provisioned for your phone. That or pop somebody else's SIM in your phone and see if you get a different outcome.
Yes that was my first thought as well. I got a new SIM, then another one. So 3 SIMs now with the same result. I've been on the phone with so many techs from Verizon/Total Wireless and none of them have any answers. If I put the same SIMs into a Moto E4 I picked up for testing, it works fine. But the 6P immediately disconnects from LTE then bounces between 3G/1X.
My next test is to try a SIM from a different network I guess... maybe Verizon is blocking my 6P. Or maybe my LTE radio is damaged somehow.
So I did this using TWRP but wasn't sure if it actually went through or not. I did it now through adb from pc and also fastboot and it says permission denied. Any idea how to bypass that?
