Hey everyone. I've faced with a problem I can't cope by myself. Once upon a time I found out despite the renewal was turned off on my phone that my phone was updated to MIUI 11. I didn't like it so much. It had buggs, terrible design and devoured phones charge like a fish. I lost my nerve and made rollback. so, I lost everything that makes a phone different from a brick with lights. After that I decided to read about ) but It was too late. So, I lost all of system settings due to antirollback policies. What about backup? certainly I hadn't made it. I had one on google drive but It didn't give it to download.
I found some efs files and managed to recover system settings such as wifi, imei, modem, almost everything except the mobile network and the internet. the engineering menu shows the efs is unknown.
It means the efs I recovered my phone isn't suitable for my phone version or I need radio.img in addition to, doesn't it?
I'm going to try input SN number via a special utility into the phone. I don't expect anything from this step, but...
I suppose I need some with radio band settings or something from it. Or I need to find the new EFS files, don't I? I remember the file I'm restoring the phone was the ancient fossil of 2016.
how much does it cost to buy up-to-date EFS? Where could I find them? Where should I look for?

now anyone please suggest me which rom to flash and kernels etcs
I am using softbank movule network
after I downgraded my 3G network is not working..
what should I do?? please suggest
With softBank you need to be using the correct APN otherwise you can get charged the wrong amount for Data costs. (At least this was the case with Windows Mobile and SoftBank.) If you are not sure after changing things I would switch off mobile data until you are. See Below.

Always backup your original rom using a backup program like Rom Manager which you can use with a rooted phone.
(Label it SoftBank original rom or something. This is peace of mind in case the phone has to be repaired and go back to SoftBank etc.)
You can use a program like APN Backup & Restore to save your SoftBank APN (to SD Card) and then restore it immediately and every time you change roms. (So you can connect to the net/ 3G etc.)
This is important with SoftBank or any carrier.
You can Google `apn backup and restore apk' if you can't access the market with your phone.
Take a look around at rom screenshots to get a feel of the look you are hoping for.
My site has a few screenshot examples here and a list of roms here.
If this was helpful - please give me a thumbs up.
Hello folks. So yesterday I was tinkering around with my phone in an attempt to load the jelly bean ROM. I am new to the world of ROM's and things, so I made sure I did my research before going into the new ROM. I got everything backed up (so I thought), and flashed the jelly bean ROM. The screen just sat there doing nothing until I got rid of it and restored my backup from CWM.
Now every time I boot, I get a screen that says "Unfortunately, Factory Test has stopped" and it cancels out wifi and I have no lock screen/power off menu. I found a solution on XDA that said to look in the EFS file for a certain folder, but when I went into my /efs folder, this is what I saw.

So there is nothing in my EFS file unless I'm reading this wrong. And I was stupid enough to save my original absolutely clean version from EFS Pro on the internal memory which I wiped. I have another backup which I think might also be corrupted on my computer from the Galaxy s3 toolkit.
The strange thing is that from what I've read, EFS corruption leads to the phone being useless with no functionality. Mine is almost totally functional, minus the Factory Test coming up.
Help please?!!
Bump. Any help would be GREATLY appreciated. Any ideas to shoot around at all.
bump. Im having the same issue

If your /efs folder is missing/empty try this:
Get back to stock

Hi, I tried to install X-Rome 3.2, everything was ok but I had no signal.
I tried to restart / reinstall / change modem and then I installed Moon Rom.
Still no signal, seems that the IMEI is not good but I don't know how to fix it.
I made an EFS backup before I rooted my phone but my PC crashed and I lost it.

Hey, I found myself in the exact situation. My SIM was fine, my phone worked normally, then only today I realised I could not sen texts or make calls.
3-4 days ago i installed X-Note ROM, not sure if the ROM did something or not. But I restored my stock nandroid image and problem persiste - no service
Would really appreciate any advice form our experts
fixed
So I ended up restoring my EFS image (glad I backed it up) and that sorted my phone out. Nothing else had helped. I thought maybe it was modem related but nope.
If you can't find your IMEI data you may be screwed. Good luck.
I guess you've read this a million times here: "Apple User switched to Android = completely lost"
This forum is fantastic, but I gotta say its SO big with so much information, I find I've spent an hour or more just trying to find the right information, and even then I feel lost.
I recently tried Slim-t0lte, but I used the wrong ROM which was the N7100 when I have a GT- N7105 device. Lost all ability to make and receive calls and worst of all I lost my 64GB MicroSD card. Photo's, music, files the lot - gone!
That was a couple of days ago and since then I've done a lot of reading and have somewhat rectified the situation.
I am now using Slim-t0lte-4.2.2.build.7.2-WEEKLY and its working great, ie. I can make and receive calls at least, and I had to go and buy a new 64GB MicroSD which set me back $70 dollars. Formatted the new SD card to Fat32 using GuiFormat and the device now see's my new 64GB drive which is great.
But here I am now with everything done and I am completely lost as to how to use this ROM. In the image below is the phone set up how I thought it would look when I loaded the ROM. But it doesn't look anything like that, so I had a play around in settings and I've got the Time, Weather up on the lock screen, but nothing else.

Also I downloaded Universal_SlimBean_theme_lockscreen_blue_bubble, Universal_SlimBean_theme_power_widgets_ics_blue, Universal_SlimBean_theme_powermenu_ics_blue and Universal_SlimBean_theme_settings_ics_blue. I installed them all through CWM but I can't find a way to load them so I can see how how they look.
My question (after all the background info above) is there a how to, a video or something which shows the features of SlimBean that a novice user like me can watch so I can begin to navigate this great looking ROM and access its features?
Thx
Greetings
I bought the device 4 month ago.
One day ( 1 week ago) I lost service, no IMEI #. :crying:
NO ROOT, NOTHING was done with the phone. I upgraded to lolipop (5) 2 month after I got it and it work fine for 2 more months.
Sent the phone to insurance company, the said the will not touch it and the insurance is INVALID because the IMEI is not presented.
I have the original box with the original IMEI.
Is there ANY way recreating it? I DO NOT HAVE ANY BACKUP...
I read on lots of posts that you need the original files of the EFS folder. Is there any way getting those files, EDITING THEM for my device and restoring that folder?
Please help...

This is what I did to fix my Verizon LG G3, but it should work for any variation.
Call and speak with a supervisor. I'm assuming you have proof you bought it. Why is it your fault that the phone memory got corrupt?
jobella, I did speak with a supervisor, they directed me to a section where it states "If IMEI got deleted or corrupted, insures is invalid", got figure, next time i will not buy a deceive with such insurance terms...
Do you think contacting LG could help? is there any specific form to fill on there website or email for those issues?
iBolski I will get the phone in a day and try that, thanks. will update
Not my day i'm guessing...
Updates:
Rooted the device with no problem (thought if warranty is invalid to hell with it..)
BUT QPST shows Phone Unknows, No ESN, Phone number is empty, Banner Unknown...
Deveice is in MTP mode. PTP not working
every try to see Software Info crushes the settings app.
No baseband V , no WiFi MAC, no Bluetooth, software version: V20h
Could it be a break?
Here is a prtscr
