Through research and a help from a few others I found hob and dhob are the partitions that contain the imei.
PDS does not recover imei after a fastboot erase all. Fortunately for you, me and a few other people are really close to finding a software fix for this issue. Stay subscribed to this thread: http://forum.xda-developers.com/moto-g/help/info-moto-g-imei0-t2925970

Seems to be a similar issue like here: [Q]Null Imei, Baseband Unknown N7105 by Emprt.
With a "broken" EFS partition.
Check this thread: Baseband Unknown and IMEI Null NOW WORKING by karlonicolas.
Maybe this will work in your case too.
Sometimes reflashing the modem/baseband can help to get back the correct IMEI.
And for the next time, please backup your EFS partition like described here: [WARNING! + GUIDE] Backup and Restore IMEI / NV Data Procedure for GT-I9305 by lyriquidperfection.
Good luck !
Thread closed. Thank you!

No 4G only 3g with 44s Modem. No other Modem works . IMEI and Baseband still there.

Hey I really appreciate any help that you can provide. I will tell the long story. My phone got corrupted while flashing different custom ROMs. Oxygen was the culprit. It completely damaged all the partition of my phone. So I repaired via 9008 modem loader using COLOR OS flash tool. then I found there is no baseband and IMEI. EFS partition damaged and I didnt have a backup. Damn it!!!!! Tons of research and googling I found how to use QPST tool by Qualcomm. I retrieved QCN file from friends ONEPLUS ONE (16gigs) and flashed it to my phone (64gigs) and edited the IMEI to my one. Rebooted the phone. tada. I got wifi bluetooth everything running. Phone signal just connects and drops every sec. It wont stay connected. but it is detected. then I thought it might modem issue. I tried every single modem out there but no luck. Finally flashed CM11s 44S Modem. Kaboom. Got the network running. but sadly it will only connect to 3g. I cant connect to 4g. No Other modem works.
1. Only get 3g service via 44s modem on any vanilla rom.
2. No other modem works.
3. Proximity sensor acts really weird. If a call comes Then I have to restart my phone to get the screen lit back. Fixed by flashing proximity fix
4. Baseband is always unknown with 44s Modem but has 3g network connectivity.
5. Other modem shows baseband but no connection even though it is detected.
Please help me guys.. What am I missing. any help appreciated.

1- Check If you have IMEI and IMEI sv and it's the IMEI that shows on box.
2- if no. 1 is true then check another sim card another operator ( to be sure that carrier is not blocking your IMEI for some reason).
3- if other operator's sim worked contact your carrier to check problem with them.

Hey thanks for the reply. I do have my IMEI from the box. I flashed QCN file using QPST tool and applied my IMEI but the thing is I only get 3g. 4G is not detected. Im not sure if something has to do with baseband files. But my friend is from my place and he gets 4g just not me. If I use any other modem other than 44s Modem the network will be detected but won't connect so i cant make or receive calls or anything related to service provide.. Do you know what to do ?

Okay let's make some tweaks :
1- backup modemst1 and modemst2 using dd (I don't trust qcn backup ) and copy them to your computer I also prefer to backup persist and fsg
2- download NEVER_SETTLE from https://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061 (you will find commands to backup mdemst1 and modemst2)
3- flash only persist using fastboot and reboot to system and check everything again.
other partitions locations :
/dev/block/mmcblk0p18 (fsg)
/dev/block/mmcblk0p15 (persist)

Same problem, I don't get 4g network. Tried everything . On restarting Even in 3g it takes around 30 seconds to regester the sim-network.

IDK what i did my opo was dead for around 3 months, the screen was responsive but totally black. then managed to recover from it then bricked it.
just figured it out. I am on my own build of XOSP[maybe it had problem idk] but had to flash my efs[64gig] backups and got my original imei back [earlier i had restored to a different imei qcn file may be it belonged to a 16gig opo] and also got 4g signal but still no baseband.
Then flashed COS13.1.2 and got baseband back, now the proximity is also working as it should and also got LTE working and instant signal on restarting the device. Now again back on XOSP everything works. If you need i can pm the efs files.

Please do email me the link to download it. Upload it in mediafire. [email protected]. It will be really helpful if you can send me the efs file.

FYI your IMEI will be lost if you do so.
So I suggest to backup your partitions first in case of everything goes wrong.
Any way I have qualcomm stock efs partitions with 0 IMEI in case if you need them

IMEI is encrypted so if you do so, you will see it in settings but network carrier will receive it 0. This means that you won't get 4g also only 3g. So I personally prefer that you flash efs of [MENTION=bablu084;70545585]bablu084[/MENTION] this gonna work except you're two in the same country.

[Completed] Nexus 6 No LTE with correct IMEI! "0" Imei and LTE!

Ok, Ladies and Gentleman I need some deep thought processing here for some help with a Motorola Nexus 6. In brief here is what the problem is, a while back when flashing Pure Nexus rom, I experienced a loss of my IMEI. I can restore my IMEI but if and when I do, I lose any 4g and LTE connectivity. The phone functions in 3g with data and phone etc... just slow as molasses but if I restore my IMEI to the one that doesn't show up my IMEI correctly I get back LTE/4g and all works fine also. I've tried going all the way back to the original firmware which was saved to computer and restoring it. Same thing, I have IMEI but no LTE/4g. restore bad efs and get LTE/4g back. I've tried going through all the factory firmware's and flashing by ADB and or TWRP and nothing firmware wise will allow me to restore the IMEI and have LTE/4g signal. If I restore the bad efs and get OOOOOOOO for IMEI when using the *#06# on any firmware version, I regain LTE/4g functioning! I am using Pure Nexus 7.1 now and can still see the 00000000 as a IMEI, if I restore my efs and get IMEI back showing correctly, no LTE/4g signal! My phone can only function as it should as long as the IMEI doesn't show correctly! I have tried just flashing base bands and other segments of any rom and still the problem persist! I have even tried restoring an EFS from another nexus 6 and still no help. It's not the sims because I've tried AT&T sims and Verizon sims from other phones and it does the same thing! I've tried flashing with a sims in the phone and without. Any ideas??? It's like somehow a correlating segment of a file is not being recognized when the correct IMEI is present, like some thing some where in the efs, IMEI, and radio are not taking to each other so to speak, unless it shows the zero's! Brain waves come on and help me out here!

Greetings and welcome to assist. Have you tried asking in the pure nexus thread to see if anyone else has had this issue ? I have seen it before when flashing aosp/cm based roms but the fix is usually different each time

So guys there is any way to restore it? or any luck to writes my IMEI from my old phone?
Nvram formated
I have the same problem because I deleted the NVRAM and unfortunately I did not make a backup. then I try to fix the problem using Miracle box by untroducing imei 1 and 2. the network has been restored but there is always a conflict from time to time the network disappears. 4G does not work and when I use 3G the SIM 2 loses the network, the MEID and always 0000 ....

If you have rooted your phone, GhostPhone app is working perfect and keeps all numbers without need to restore them manually on every update or changed mobile network settings(the last oftendeletes IMEI on many MTK 6xxx phones). If no root access - use MauiMeta to flash them from PC, it is not hard for use from unexpirienced people.
