What Exactly problem you are facing...If EFS is lost you can backup again but provided you have not corrupted your IMEI...
ok

Hi,
I just rooted my Galaxy Note 2, build nzo54k.n7100xxdmc3.
I rooted using this guide: http://forum.xda-developers.com/show....php?t=2143479, method number 2. Now I cant use networking. There is a cross over where the network bars use to be. Everything else seem to be working fine. It rebooted a couple of times tho. Can anyone help me with this problem, how I can fix this. If I press "mobile networks" it tells me that I have to insert a simcard. I have the simcard in and tried to restart the phone several times.
I would appreciate any help that you guys can give me. Thank you!

Link you've attached is broken ,
Strange , Could you check if your device shows IMIE number or it shows null ?

EFS file is where your Imei , Mac address and few more important files are stored as you phone doesnt have an IMIE it shows as unknown so that is the reason your unable to make calls or the Sim is not getting registered, What you could try is to Flash a Stock Firmware and check if the IMIE shows up or else will have to take it to Samsung Service Center and will have to Pay for the Service.
The Guide which you've Followed dont say that you will have to backup the EFS Folder i've informed to update it on OP any ways not your mistake .
Always remember 1step after Root is to backup EFS File
Getting to know your EFS folder on Samsung Devices
Common Files We Back up
I am sure you have heard of critical things you need to do when you mess with an Android device right? One of the things that always come up is to back up your devices.
Backing up data usually involves making sure those contacts, calendar entries, memos, messages and special media that you may have kept within the internal memory are kept safe. The general rule when flashing and rooting is that often times, you may have to end up wiping all your internal memory data.
Some people tend to take this further and back up the internal data of apps, which is only possible if you have root access on your device. This is especially useful for those who like to play games as well as flash custom ROMs.
There are those who would also recommend that you back up the entire image of your current ROM state by making a Nandroid backup so that you can get back that exact state of your ROM if you mess up with flashing a whole new one or if you didn’t like the new ROM you tried and wanted to get back.
For Samsung devices, there is one other thing you may want to secure in a back-up chest – your device’s EFS data.
What is an “EFS”?
EFS refer to a folder location called /EFS in Samsung’s Android devices. It is a very sensitive folder hidden within the deepest core of your smartphone’s internal file system and is very essential to the functions of our smartphones.
One of the very sensitive information you can find in this folder is the information regarding your phone’s unique IMEI number. As you may have guessed by now, it also contains other unique identifying numbers for your smartphone including the MAC address for your smartphone’s radios, as well as the MEID, ESN, as wells as the registered phone number for locked smartphones.
The Danger to EFS
Normally, the EFS folder is highly protected. Rooting and flashing ROMs normally do not touch this part of the device. Unfortunately, there is no such thing as a controlled environment where everything goes according to plan in the real world. Sometimes, a process hits the EFS folder, or ends up corrupting the data within.
The EFS is also likely to be corrupted by users who like to unlock smartphones since it usually involves editing the data within the EFS folder. Once the data is corrupted, the only way to get it back to working order is to restore the data as is.
The loss of the EFS folder may cause your phone to no longer be recognized by your carrier or some of your radios may no longer work. This breaks the device as a whole no matter how many times you reinstall a ROM.
Even if you are not planning to modify the EFS folder itself, you can still accidentally corrupt that data. That is why even if the process of rooting and flashing ROMs does not require you to do so, it would be prudent to back up the folder. This would be a classic case of being “better safe than sorry”.
Why Modify the EFS
Messing with the EFS is what you would call some “high level stuff”. People normally don’t mess with this folder due to the high risk of making the smartphone unusable. The most common use of editing the EFS folder is to unlock the smartphone so it can be used on other carriers.
Most users usually steer clear of this folder. If you really want to mess with it, look for us tomorrow as we show you how to back-up your EFS folder.

1st flash a stock rom and see whether u get imei and baseband back or not.. if it didnt get recovered then service centers can only help you as u didnt make a backup of efs..
There is a slim chance its not his efs,
I did pretty much the same as he to get root thru the toolkit, and had no network, I found I had no APN configured
Perhaps check this.
Settings... more settings .. mobile networks... acess point names.
Make sure you have something here.
if not you will need to search for the settings for whoever your provider is.
good luck

Check your SD card on another device. The card could have gone bad (can't write, occasional problems reading, can't format). I've had it happen to me twice.
If system files are on the SD card, read-only can cause problems. Last time I had that happen, I believe I ended up reflashing a clean stock ROM and starting over
Recommend saving app data (not the apps as one of them could be the problem) before nuking your flash though.

The point is Katkat v4.4.x dont allow apps to write or install in sdcard, you just change The permissions to write.
In your case , install by a clean setup The Stockrom, root it, change The Permission to write on sdcard at Platform.xml with a root Explorer.

maybe,install proper driver first,after connecting the phone in fastboot mode,you will see that computer starts to install the driver,let it install first(it will show device ready for use)then try to flash.
So your phone is able to boot? Why dont u delete ui.zip using file explorer?

MM and Samsung roms fully support reading and writing to the sdcard. All that is required is for the app to ask for authorisation.
If it doesn't ask it's a bad app.
ADM also works fine with MM and sdcard.
Hi all,
My Samsung Galaxy S9 (SM-G960F) shows IMEI “Null”. This prevents it from recognising it has a SIM card.
* Device is rooted. “no verity” blob installed.
* LineageOS installed successfully.
* No partition backups were done; I wasn't aware of “EFS” or anything like that when I started the procedure.
* Using a root filesystem browser, the ‘/efs/’ directory is apparently empty.
I know the correct IMEI (it's printed on the back of the case). How can I record the IMEI into the device so that it knows its own IMEI and uses the SIM card?
Does this require generating an EFS partition (if that's the correct term)?
I have the correct IMEI. How can I write that to the device so the operating system can read it and use it correctly?

Did you solve the problem and how?
This happened to me with one old galaxy s3 phone and at the time, there was no way to fix it. At least not for free. I also downloaded those tools that the service technicians use, I found them illegally and they didn't succeed either. And here, too, no one knew the way. Maybe there's a free way now, I don't know.
