Hi guys,
I have a slight problem here, I was using my rooted with magisk and running lineageos17. Unfortunately, bluetooth wasnt working so I reverted back to stock, which fixed the bluetooth problem. I tried rooting the thing then with this method:
https://www.xda-developers.com/install-android-oreo-samsung-galaxy-s7-exynos/
Unfortunately though, this killed my imei. I tried restoring my efs partition with twrp; even tried reflashing the stock firmware, all to no avail, my imei is gone.
Is there any way I can restore it or have I turned my phone into a fancy paperweight now?
Would be cool if anyone could offer me some help,
best wishes,
derelektrischemoench
// edit: I managed to get twrp installed and was able to restore my twrp- backup which i had made before this whole endeavour and voila: the device is back online, has an imei and is able to connect to a network. Hell yea. Thread can be closed, I guess.

Hello. I am having a bit of an issue. Today after I decided after having fun with touch wiz i decided i wanted to go back to a backuped copy of ParAndorid and we it go to the home screen i got repeated errors of com.andorid.phone so i rebooted and since I haven't had any cell service. I put it back to factory, tryed different roms and such and non are working. I even tired the ##76786# and got nothing. Any ideas?
Im guessing you lost your IMEI, did you happen to back it up? http://forum.xda-developers.com/showthread.php?t=1852255

as far as ik its still there. Its showing a 99000020.... number. No, i didn't know if i had too.
Maybe your sim got jacked or something? Did you just do a reset on your phone or did you odin back to stock? If you just did a reset maybe odin a factory image and see if its corrected? Also before that maybe you can try flashing the radio/modem and see what that does?

I just did the factory restore in the rooted version of touch wiz i have installed and it corrected this issue. I ended up calling them to make sure it was nothing on my end. It was werid that a factory restore insdie of touch wiz would fix something that odin couldn't.
But yeah topic [solved] Thank you though x714x
Cool, glad you got it fixed!
Hello Everyone,
I ran into a problem today while trying to update to JB. I installed AllianceROM_I9300_JB_XXELK4-Base on my Galaxy S3. I noticed It changed the baseband to something different of what I have. Since I was not able to make calls, I decided to restore my backup trough CSW.
I noticed then that my IMEI had changed to something else.
My status now is: The IMEI I had is now different, the modem I had that used to work is not working anymore, I flashed a different version of the modem but I cant get it to register on the network.
Any help is appreciated.
My phone will not recognize Verizon as its carrier or connect to a cellular network in any way. Settings > About Phone > Status > IMEI reads "0." I have, in some capacity, "lost" my IMEI.
I understand their are a lot of threads on this topic, however, I (unfortunately and ignorantly) have done a number of things after the actual losing of my IMEI and I am not sure the current state of my device or if a backup of my IMEI exists anywhere.
First my story. I successfully managed to get one of the early nightly builds of CM10.2 running on my phone and all was well. After updating to a more recent nightly via the CM updater, I noticed I had lost cell service in all capacity. Confused, I decided to not take any chances and revert to a CWM full backup I had made while still running CM10.1 stable. Still nothing. At this point, I thought that something was wrong with my firmware, and so I flashed a zip containing the latest Verizon firmware successfully (same that was installed previously). Nothing.
Not really understanding that one could lose their IMEI or the potentially signs of such loss, I decided to go all the way to stock via odin. The image did unlock the boot loader and grant SU, but did not wipe user data. Thinking it would help, I wiped data/factory reset within the stock recovery and then reflashed the image. Of course, still nothing. This is my current situation.
So my question is this: do I have any hope of recovering or "injecting" my IMEI? From my understanding, the Samsung mechanism designed to backup the IMEI in these such instances is broken. In fact, it probably "restored" it to a bogus null value. I think this means that I now have no IMEI information on my device. If so, does this mean I can manually inject it somehow? I have tried methods that purport to build the files on a pc and then move them to the device but I cannot access any of the Qualcom menu's that necessarily put the phone in a certain USB mode via the phone dialer. I get "no mobile network available."
Also: I still have my CM10.1 full CWM backup from before I lost my IMEI. If this backup contains the information needed to restore my IMEI, is their any way I can retrieve it? I think this is my best shot, but I'm not sure.
I would like to know if my new phone is a paperweight, since I am still within the 14 day return period. If I have indeed bricked my phone, there is a slim change that I can reset everything back to stock and play dumb with Verizon to get an exchange.
I apologize for the ambiguous vocabulary and/or description. I have a good working knowledge of most of the stuff on xda, but a lot of the language used in forums regarding IMEI restoration is foreign to me.
Thanks in advance for any help!
You have to Odin a stock ics image, or restore a backup if you have it, and dial *2767*3855#.
This should fix your imei and eri status by reprovisioning your phone.
Also as soon as you reroot and get up and running again, make an imei backup so you won't have to go back to stock if you have this issue again.
You could manually inject it, but a moderator has to grant you permission to use the thread. However, manually injecting it with qpst will leave your phone in roaming (not actually roaming, but the status icon won't go away) because it won't fix your eri number.
Use this option first, if it doesn't work you can try injecting it.

I used qpst to restore my imei and then used this method to get back without using odin, if you haven't already done so. I also think you can get your imei and eri back without using qpst with this method. I had already restored my imei and eri wasn't saying 5 like it should.

Edit : I forgot, once you have your imei and eri restored and backed up. Don't forget to flash your modem back up to the version you want.
I am having a huge issue with my phone. I have been flashing custom roms for the past few years and this is the first time I have ever ran into a issue like this. I flashed SlimRom 4.3 build 2 a couple weeks back, it was taking forever to switch between 3g and LTE sometimes up to 5 mins to lock. Not to mention the signal was super low. I ignored it for the most part as it is a newer rom and figured it was just a bug and would hold off for now till kitkat released.
Then my phone would just start random rebooting about once or twice a day. Then on my way home from work i was bluetoothed to my vehicle when it did a random reboot. After that Ive been stuck in 1xRTT since. I also managed to loose my IMEI and PRL version they are both set at 0 and I do not have a backup. Has anyone else ever had this issue? I don't have a clue how to get it working again. My phone is out of warranty I am in the midst of flashing it back to stock to see if that works. Ive searched for hours trying to find a fix. Thanks.
Reverted back to stock.still no luck. Also play store won't work. No connection wirh retry button even while connected to wifi
What firmware/radio do you have? If you've been on custom roms a while you might need to update your radio baseband (most current is VRBMF1). You can flash an updated radio without regard for the Rom you're using.

The imei thing is a separate issue. I lost mine without a backup when I first started flashing roms... I think it was cM at the time. I ended up going all the way back to an early stock image, grabbing the OTA updates and then rooting and flashing all over again. I don't know what part in particular got me my imei back.

Do you mean a backup of efs partition or a nandroid? There is a thread at rootzwiki about recovering your imei-efs items. When u get it back do
Su
Reboot nvbackup
In a terminal then you wont have to worry about this again. If you have a nandroid restore it and you'll b good.
Yes my efs folder was completely empty. I reverted back to stock 4.0.4 still had a "0" for IMEI so i used QPST and entered in the IMEI manually and it stuck. I have signal back now. I just got factory mode off. Now my phone is stuck on "Activating", a factory reset should fix that. So this is resolved. Thanks for the help.

Is this the fix to get everything up and running again (flash back to ICS)? I was about to start my own thread until I read this. I lost my IMEI, ERI and MEID but didn't back it up first (I know I know ... boo). I manually input my IMEI using QPST like you did and was also able to fix my ERI and MEID and now I have data and text, but still no voice connection. I've flashed a stock (rooted) ROM and tried the reprovision code *2767*3855# and the RTN codes ##786# & ##72786# but nothing happens (I've seen in other forums this only works in ICS and not JB). Last night I downloaded a stock unrooted JB ROM (4.1.2) and ICS ROM (4.0.4) and am planning to ODIN back to stock and complete a factory reset to see if it will kick the gears back in motion again.
I'm not meaning to hi-jack this thread but confirm this is the solution to completing a non-backed-up IMEI/ERI/MEID fix.
-Edit-
There are tons of threads out there starting with "I've lost signal, what happened?" and ending with "I'll report back and let you know what I've found." or "Verizon replaced it for me." but none offer a viable user solution. I'd love to see the answer posted so other searchers out there can find help.
I can confirm everything you did will restore your IMEI/ERI and connectivity. I did all the steps you did (manually input IMEI and use the utility to repair ERI and MEID), then reverted back to unrooted stock using odin. I still didn't have signal until I did a factory restet IN THE ROM. Going back to stock using odin and doing a factory reset in CWM didn't fix the issue, but going into the phone's settings and completing a factory reset from there caused my signal and connection to come back.
Hello,
I started with Galaxy Note 2- i317M (rogers, canada), rooted with DN3 V4 beta installed. But I wanted to try DN4, so I created a back-up using TWRP and tried installing DN4. However, I later realized that it is not for the LTE versions yet and phone did not recognize SIM anymore. So I wiped the data and tried installing dn3 v5.5, but the phone still did not connect.
Losing all hope I installed DNv4 again, but it still did not work. So i finally just tried restoring from the back-up I made using TWRP. Everything in the phone is same except no network.
Finally I tried restoring from back-up after doing a complete wipe of internal storage and everything except the external card. But still the error does not go away. I researched more about the error and the fact that my imei shows up as null/null. I used the instructions of using EFS professional, but it did not work. The model number in my phone now shows up as SM-G900F and baseband shows as unknown, and it shows DN3V5 Rom despite the clean-up and restoring from DN3V4.
Any guidance available on this please...I need specific steps because after 12 hour search and try-outs I am lost now.....
UPDATE:
Solved it! Here is the solution for anyone in this problem
http://forum.xda-developers.com/showpost.php?p=46231268&postcount=4
worked like a charm.. No reason to throw this and get a new phone
I have had this problem. It didn't happen whilst flashing though. My imei number is now a generic one and I had no efs backup. After 5 days of trying everything I can find I'm giving up. My note 2 is dead as far as I'm concerned. As far as I'm aware to get my imei back I'll have to send it for repair so I'll buy another phone and not a Samsung
I don`t think your phones are dead. I didn`t try it personally, but I`m sure you can restore your EFS back. Just you need to do some research, maybe you could start here:
https://www.google.ro/?gws_rd=ssl#safe=off&q=how+to+recover+efs+folder
Do not give up, read on end you will eventually do it! And, by the way, next time maybe you don`t forget to back up before doing anything to your phone!

I did back up. with both titanium backup and twrp but it is not working. And I dont think I will give up. I will format is all together and start over if i have to.
Do you think it will work if I format it entirely and start over?

Hi! I am using a LG Nexus 5. Previously it ran on Android Lollipop , after which I tried to update to Android Marshmallow using the official OTA update. Unfortunately, after this update, my phone stopped reading my sim card right from the first bootup. On dialing *#06#, I receive a blank space instead of the IMEI value. further, the baseband is listed as unknown in the phone settings. Although the functionalities other than those of the baseband processor (such as calling, sms , gps) run flawlessly. I have never played around with this phone so it has a locked bootloader and does not have a root access etc.
I have been scouring the internet for around 2 months now but could not find anything conclusive , so I decided to start a fresh thread here.
What are my best options to restore my phone-turned-tablet back to a phone with functional cellular capabilities?
So sad, i hope u got it fixed, i did an EFS backup, it's dangerous to not have one in case of EFS partition get wiped :/

No, I have not been able to find out yet how to proceed. Please suggest me how to take the EFS backup and how should i proceed further after taking the backup
same problem
I have a Nexus 5, did the OTA Marshmallow update, now having the same issues you mentioned.....Blank IMEI #, Unable to read sim. Everything else works, except calls and sms, right now its a tablet too. If you have found a fix let me know. Thanks

No root access and a locked bootloader.. and still semi bricked during an official OTA? I wondered how many more are having this problem unreported?
From what I have read so far, does seem somewhat common. If I would have known about backing up the EFS partition, I would have. I had the phone for two years unrooted and no problems at all.
