Hi guys!
I'm sorry if it's been asked before.
I did clean install from CB 3.5.3 to 3.2.7 and flashed official twrp everything works except LTE which is not turning on.
I flashed 3.2.6 but same problem.
I did LTE only by using USSD code but it doesn't work also, now I'm stuck to 3g only can anyone help me in this regard?
Which TWRP are you using? There's a modified version to deal with this problem-not completely flashing ROMs. My suggestion is to dirty flash just the modem and firmware for 3.2.7 separately. If that doesn't work, you will have to clean install (wipe dalvik/art/system/cache) then flash the 3.2.7 firmware/modem, re-wipe, then re-flash 3.2.7.
Flash modified twrp 3.0.2-19 and then flash 3.2.7 Firmware + Modem. Wipe. Then flash the ROM.
VoLTE work around on stock / CB
Clean Flash Stock / CB rom using twrp .
You first have to extract 4 files contained in the zip file attached .
Now make a efs backup from twrp
Now go in twrp>backups>device serial number folder>the most recent backup you made folder
And paste the 4 files and replace them with your efs files Then restore EFS back up only using twrp.
That worked for my friend on 3.2.6 stock who completely lost VoLTE , tried every thing found this solution by hit and trail hope it works for you as well.

Anyone tried this method?
Make sure you have chosen "Preferred SIM for data" as your LTE SIM and not your other sim. Otherwise LTE won't come on.

Some questions here...
I have just rooted my stock DMF2 rom and got efs backup. Then i flashed the latest perseus kernel.
I wanna flash the latest omega rom but i read somewhere that if i flash a non DMF2/ME6 based rom, i will get a imei error.
Is there anyway i can flash omega rom without getting an imei error?
Thanks for helping and sorry for my english.

well try it yourself since you have a backup.
Make sure that also have a backup of your Modem and Build, (found in settings under Baseband (modem) and Build Number).
because your EFS backup would work 100% if both of these were the same when you're restoring.
If things didn't go on well, then you can reflash the ROM.
in case the backup wouldn't work (works once then no signal on next restart), then what you have to do is as follows:
1-Flash the ROM that has the same build number as the one you had when you backed up your EFS
2-Restore your EFS and restart
3-Restart again, if there's no signal, then restore your EFS again and restart once.
4-Downgrade your Baseband to any version (I prefer DME4).
5-Perform an OTA update (OTA works if you had status normal and an IMEI and phone signal, so you need your EFS to be restored and the signal working, for the status normal you need 0 flash counts and Full Wipe of data through VolUp+Home+Power).
6-If you have ROOT, then don't touch Install or Install all! click on later.
7-Get Odin Mobile Pro (you need the Pro Version). and run it.
8-Click on "OTA/ update.zip". point it to "/Cache/Fota(might find random numbers here)/update.zip". In case you can't find the file, just use Root Explorer, and copy the update.zip to anywhere on the SdCard0 or extSdCard, and Point Odin to it.
9-Check the EveRoot Option and Odin Pro.
10-Flash the ROM.
now you'll have the same build number, but your baseband is now updated correctly. Just restore the EFS one more time and restart and it should work.
Note: If you may tell me your current baseband and buildnumber, I could save you time by giving you my files if I have the same as you.

Bump, I'd like to know this also.
As title states, i lost my IMEI/carrier signal after flashing the latest nightly (2-27), and haven't been able to get it back
I tried to inject my imei backup, but using the *#7482# to enter qualcomm usb settings hasn't worked, not sure why (maybe it was changed in kk?)
I tried flashing a modem, but i can't find the appropriate kitkat one for my phone. the only one i found was for jellybean.
Any ideas guys?
I can't seem to get any dialer codes to work
If you are on ATT Flash d2att instead of d2lte

There is no KK modem because there is no official KK ROM.
Try flashing the latest AT&T modem.
If flashing modem doesnt work. You need to restore back to stock then make sure everything works. Reboot back to recovery and do a backup of your rom and EFS. I use Philz recovery. After you make ur back up go ahead and flash custom rom.
If you did backup your EFS in recovery. Just reboot back to recovery and just restore only the EFS. Save you from reflashing back to stock.
could someone post a file of their nandroid backup of the stock rom? flashable thru twrp please.
I tried flashing the OTA on a stock rooted rom with twrp installed and my phone didn't like that. (rookie mistake:silly now any restore, rom flash, wipe, ect . will not work and my phone boots straight into TWRP every time. So if you could give me your nandroid backup w/o any data, or if you have a better solution please give me that. thanks!

We need more details really.
But if you can get into recovery, have you tried a factory reset? Then reboot.
We need to know your TWRP version, (KK or not), What ROM you were on prior, and what ROM's have you flashed since.

I was on the latest snapshot of CM11 and then i flashed LS970ZV9_DEODEX_STOCKROOT_1_13.zip
then i got the normal notification for the available OTA update (ZV9>>ZVB i believe) and i forgot that OTA's and custom recoveries don't work well together.
So I've literally wiped everything except for sd/data/media (or what ever holds all your photos and music ect) and I've tried restoring ALL my backups, nandroid wont ever work...
I believe installing a new recovery MIGHT work although I've tried two different versions of TWRP i had on my phone. (current TWRP v2.6.3.0)
Requesting:
1. Someone's NANDROID backup zip file with no data, obviously
2. CWM recovery for LS970 (lg optimus g) sprint
3. Drivers for XP PC to be able to access file system of my Optimus G

If you are on a stock rom you should be able to use freegee through the play store and it can install CWM if that's what you want.
Have you tried reflashing a stock rom? Why did you flash the zv9 when the zvc is available? I would try flashing that in recovery, twrp should flash it.
There are a few other options as well. Check the brick recovery thread and it will lead you to a teeny bin, you can use the programs that are suggested there and it will flash a recovery and unlock.

I think you can also use fastboot to flash a different recovery and unlock.

Yeah i tried reflashing all the roms i have on my phone and i tried the ZVB/C stock (deodexed) rom and they both failed flashing.
ZV9 was the only success until i tried that OTA. I'm downloading the CWM recovery zip file right now to flash in TWRP. could you tell me how i could move that file to my phone within TWRP? I have trouble finding out how to access the file system from my computer when my phone is in TWRP
Thanks for the quick replies!:good:

That's what we needed to know.
I think the issue is your modem. ZV9 is for ICS. ZVB/C is for JB/CM/AOSP
So if you still have your recovery or any unlocked recovery, flash the ZVC modem from the teeny bin thread. Then I would suggest a Stockish Rom. That should get you going.
Hey guys. I installed cyanogenmod 11 yesterday on my note 2. i ran into some problems. There was no service, imei and baseband fields were blank. i couldn't dial the *#After countless afters searching xda i managed to fix it by reverting back to the stock Samsung firmware (4.3).
My question is how do i install cyanogenmod 11 and also get network service now that i have my imei and base-band back. I'm not familiar with efs backing up or what to do with it to get network service working on a customer rom.
Any help is appreciated. thanks

To do that you must be rooted and have a custom recovery.
Download and Install PHILZ recovery latest version.
Make Nandroid backup using recovery. Keep it somewhere safe.
Download doctor Ketan's Multitool zip file and install it via recovery.
Now you will see Aroma window with various options. Chose EFS BACKUP.
Exit Multitool and restart the phone.
Copy EFS backup from internal memory card to Phone (approximately 20mb size)
Now Flash any rom u like.
Press thumps up if you found this suggestion helpful.

Hello other solution is to use TWRP recovery , when you do a bakup whis this recovery you can choose what you want to keep : EFS, data, system etc... and where int SdCard or extSdCard.
I hope this can help you.
This is killing me.
I have the LG D852 v20j from Koodo/Telus in Canada stock 5.0.1
I bumped and rooted and installed TWRP 3.0.1 (unofficial)
I then backed up everything via TWRP (including EFS)
I also followed the manual method here to generate two .img files for EFS backup:
http://forum.xda-developers.com/lg-g3/development/efs-lg-g3-efs-backup-restore-t2907329
I upgraded to a stock based MM ROM:
http://forum.xda-developers.com/lg-g3/development/canadian-d852-stock-bumped-rooted-rom-t3056843
IMEI was still there
I flashed the MM Videotron Modem he provided and I lost my IMEI number
Flashing the TELUS MM Modem doesn't work either
To restore it I have tried:
1- Restoring from TWRP the EFS alone
2- Reflashing the Dene ROM
3- Restoring EFS via manual method (works sucessfully but still "Unknown" IMEI)
4- Completely restoring via TWRP and even then trying the manual method
So, I have two backups (manual method and TWRP) and I still cannot restore my IMEI and get on any network.
I thought backups were foolproof.
What do I do?
I just had to flash an old LP BELL modem on the MM ROM and it worked. No need to restore efs partition.
see here for solution:
http://forum.xda-developers.com/lg-...rooted-rom-t3056843/post66184123#post66184123
try flashing the MM stock rom you flashed and check if the IMEI is there. if it is, your best bet is to - from within that rom - go back to stock kdz/tot method and hopefully you get it back, you can then restore your backup with IMEI intact. this is what fixed my "unknown" IMEI from this exact situation except different model. another thing you can try before the kdz/tot method is to flash the MM rom and then restore your backup but do not reboot your device, after you restore your backup, flash the appropriate bootstack then you can reboot.
Ok, so the issue is resolved.
I just had to flash a working LP (BELL in this case worked) modem
