I have a Cricket branded galaxy s6 on the Cricket network and I was having some issues with the fingerprint reader which led to an eventual factory reset after trying many other things and of course I forgot to turn off reactivation lock beforehand. When booting back up I realized my Samsung account wouldn't sync up and I realized what I had done and after trying numerous things to fix that problem it led to me flashing the firmware for my phone and of course I didn't make a copy of the efs folder. So now my phone cannot connect to any network because the IMEI number is showing as unknown and so is the sim card status. So my question is... Is there anything I can do now to regain network connectivity?
If you are rooted you may restore nv_data.bak and nv_core.bak, that may get your IMEI back, if not, you can purchase a new and clean CERT file to get a new authentic IMEI back.
Would the phone have to have been rooted before deleting the IMEI number? I still have the original IMEI number written down as well

First post, long time lurker, so i'll start with a big thanks to the entire community for all the help you've unknowingly given me.
I just got a nexus 5 to replace my original n5 which has a broken screen. I took a backup of the original and restored it to the new one. Unfortunately i didn't know what EFS was, so i restored the old EFS to the new phone. IMEI went to zero. HUGE BUMMER.
I was able to fix the IMEI with QPST, but the new phone will not connect to the network. I've run a check on the IMEI and it is not blacklisted. Without incriminating myself, lets just say that i'm positive that the new IMEI is good.
The phone recognizes that i've inserted a SIM but shows no signal. I've tried to search for networks, i've checked the APN settings...
I REALLY don't want to send this to LG since they can't give me a price or even a ballpark figure without me shipping them the phone...
Any advice on next steps would be greatly appreciated.
What should i try next?!
flash the factory img and do not restore your efs on it.

I guess i should have mentioned that i've flashed factory also. Currently the phone is on the latest firmware, unrooted, locked bootloader. Flashing factory had no effect at any point.
I bought this phone on Swappa BTW, so i am assuming there are no hardware issues. I'm not at all certain what else may have been screwed up by having another phone's EFS restored over this "new" phone's EFS...
More Info
I am able to attempt to manually select the network. When i search for networks, the available networks are shown, but when i try to connect it shows the Registering dialog for quite a while, then fails. This is the same behavior as a working phone without a SIM installed. The odd part is that the phone will recognize when a SIM is installed or removed. It seems that my problem may be that the SIM is not being read properly or the data is being lost/corrupted between SIM and antenna. Is this possible? Is this EFS corruption? is this something i can fix? Please help.
Bump?
Hello dear ones, I'm lost and I need your help.
I've bought a used SM-g920f, knox x0. It worked flawlessly. Until the first evening when in the middle of a phone call the phone app crashed. After resetting the phone it was still unable to connect to network. I have noticed that baseband/IMEI were set to unknown and so it could not read my sim card.
First I have tried the obvious - upgrading from lollipop to marshmallow. It went easy but did not help. Neither did help resenting to factory settings.
I have rooted and installed twrp recovery adb and stuff.
After almost two days playing with it, I seem to be out of options.
What I tried:
Flashing Different roms - stock and non-stock. (G920FXXS3DPB2_G920FXEU3DPB1_G920FXXS3DPB3_HOME, G920FXXS3DPB2_G920FOXX3DPB2_G920FXXS3DPB3_HOME, Pure-Stock.ExtraLiteROM_XXU3DPCA.DEODEX-v5.5.by.ambasadi, XtreStoLite-ROM-3.0-Final-DPCA) - I do not know the country of origin of this device. (the back is from testing unit), is there some way to know correct original stock ROM ?
Flashing Different modems - (G920FXXS3DPB1_Modem_TWRP, G920FXXU3DPB6_Modem_TWRP, G920FXXU3ZPA1_Modem_TWRP)
Checked sim card in another phone/different card in this phone - if sim card would be invalid, would I still get missing baseband?
Xposed Imei Changer - it did change IMEI. But that's it. Baseband still missing.
*#0011# and other *# stuff..
And I have wiped /efs (it did generate new nv_data. Guess now even broken IMEI would make ma happy)
Any ideas ?
How can I know what can be wrong? /efs partition? wrong firmware combination? hardware issue?
In Samsung Phone Info I get empty on Modem Board, Hardware Revision,Samsung Serial Number,Baseband Version.
Than you for any help or idea!
tried smart Switch emergency reinitialization?
Just to be sure, knox is triped now?
Greetings,
I would like to ask for anybody's help on fixing a dilemma that I can't seem to solve due to how limited my knowledge is.
Colleague messed up his phone very bad, he was trying to "Unlock" his phone through SamsungTool. Here's what happened;
1. Phone is carrier locked.
2. Read a guide that suggests that he should flash a "lower" baseband.
3. Flashed a lower modem file through Odin. Didn't backup EFS. But did take a photo of IMEI and S/N using *#06#.
4. Faced with DRK error. Phone is inaccessible.
5. Rooted the phone to remove DRK error.
6. Phone is now accessible. Used *#06#, IMEI is now 3500000000006, S/N is none.
7. Force flashed IMEI using Samsung Tool. Luckily, he took a photo of the *#06# details.
8. IMEI is now in place but MEID is different, S/N says "None"
Is there in anyway in fixing this?
So I have 2 phones (both S7e), but one lost its IMEI / having "can't mount /efs" problem. This phone unluckily doesn't have a back up of its own EFS / IMEI digitally, but it still has the phone sticker that has its associated IMEI. Now, my plan was to TWRP restore a backup from the working phone to the unusable one so that I can fix the EFS problem and right after, "edit" the IMEI number to what it's supposed to according to the sticker left on the phone.
My questions are:
1) is this possible?
2) if so, can someone help me find out the proper steps/tools to help me change the IMEI on the 2nd phone with the temporarily duplicated IMEI
3) any tips on making sure I don't have both phones running and get blacklisted for having 2 phones with the same IMEI on i was thinking just to leave both phones on airplane mode or at the very least, turn off the first phone until I get the second phone working

Hello there, I got a Pixel 3 from one of my friends recently, after some days i reset the phone and suddenly SIM stopped working, when i checked the IMEI no. of my phone it was "004001520220002" this. But my original IMEI before reset was 99001200********. Now i had no idea what just happened with the IMEI. that new IMEI is blacklisted & hence i cant use the network on this, so i tried to recover my IMEI by using root method. After messing around with my device for a couple of days, i was successfully able to root the device and install Xposed Framework in order to change the IMEI no. I have changed my IMEI no back to its original but network is still no where to be seen in my phone. *#06# will tell me the old good IMEI but i am still unable to get signals on my phone. What should i do now ????? I am not an expert with the ROMs or modifying the OS. PLZZ HELP ME GETTING MY PHONE SIGNALS BAKC PLZZZZZ
How did you able to recover your imei, i'm going through the same thing, please share your procedure bro.
