Only (real) issue I have seen with WiFi not working on STOCK ROM is a user called @samuel clarke had issues with his, and it turned out that his motherboard was fubar. And he had to send it off for repair. It may be possible that your MB has a similar issue, although it could be something very trivial causing it also.

Not really messed with restoring efs yet I'm afraid :-/ - although that day will come soon, just flashed TWRP myself ready for a custom ROM. You may have to use another tool to restore efs maybe? - still scanning around myself filling my brain with information.

my wifi is switching on and is finding the networks just when i connect it freezes for a bit then says unable to connect to network

only seems to be since ive returned to stock does the baseband,modem have anything to do with wifi?

Well the EFS backup/partition stuff contains WiFi Mac address etc, so could be that it is corrupted slightly? --- Best case I can think of now at this moment in time after reading a fair bit, is to re-restore your EFS and ROM etc and see how it does?

You have the 14MB or so EFS file? -- I read somewhere earlier on how to restore, just trying to find the link now!
---------- Post added at 04:03 PM ---------- Previous post was at 04:00 PM ----------
simpliest method for efs backup (from device):
1. Download a terminal emulator from playstore
2. Open it and type: Su
3. Allow superuser permission when asked
4. Type this: Dd if=/dev/block/mmcblk0p11 of=/storage/extsdcard/efs.img bs=4096
5. Check your external sd card, there is a efs.img file (14 mb), do some copy in a secure storage.
For restore:
1. You need your efs.img in your external sd card
2. Open terminal and type: Su
3. Type this: Dd if=/storage/extsdcard/efs.img of=/dev/block/mmcblk0p11 bs=4096
4. Reboot

Not sure how this could help, but maybe if you could potentially restore using the same process if you have the file on your SD CARD?

OK closest I can find it seems, while you may not have backed up with this, I guess the principle is the same... the restore may work

And....

It has a restore option in the GUI
EDIT2: Since you have the EFS file(s) you could try it

Ahh bugger, it could be that you have a dodgy EFS file backup then :crying: -- You may need to make a new backup, it's possible if it's currently corrupted it will still read the settings properly... However there's always that risk, You may need to seek advice from a Dev I think or someone who is fluent in EFS restores/backups.
Sorry I couldn't help, good luck though man, let me know how you get on.

ive checked both efs files and both seem ok just getting them to flash back on phone thats been a pain how are people flashing them from a aroma efs backup>

I had similar issue with wifi, so I flashed this [URL="http://forum.xda-developers.com/showthread.php?t=2461929"]ROM[/URL], try it may help you.

You'll most certainly have to seek a Dev's advice then or someone who definitely knows what they are doing, For now I wouldn't try and flash anything else or mess about in case you manage to lose EFS data and/or brick your phone.
EDIT: Is there no restore option in Aroma when you reinstall?

EDIT2: You may have one final option - Emergency recovery mode via KIES _ not 100% sure if it'd work, but it may help you at least get back to stock unrooted with EFS back to normal.

[SOLVED]IMEI Null , Unknown Baseband - (*update) and recover IMEI

[SOLVED] [temp. fix] IMEI Null , Unknown Baseband
Confirmed working with i337 and i337m
Original problem:
Hi
I have received an i337 s4 with imei nul/nul and with no baseband (unknown) - see attached pics.
The user stated that he played with some menu from Samsung secret codes.
It's on stock recovery, download mode doesn't show any flash counters, binary and sys status as 'official' and write protection 'enabled'
Also the home screen shows a certain menu with a notification 'update device information' see attached pic.
I have done a factory rest via stock recovery, still showing the same issues.
How can I solve this hopefully?
update SOLVED:
Thanks to Colonel Sander aka Quasimodem for all the help, here and over hangout.
After having problems with QPST/ EFS pro etc, in repairing, I flashed his efs.img , this removed the home screen error notice and the phone was working normal - still with IMEI = null / null and baseband = unknown
Today he made a flashable zip, which helped me fully flash his efs,
package_extract_file("flash_image", "/tmp/flash_image");
set_perm(0, 0, 0777, "/tmp/flash_image");
ui_print("Installing EFS...");
assert(package_extract_file("efs.img", "/tmp/efs.img"),
run_program("/tmp/flash_image", "/dev/block/mmcblk0p10", "/tmp/efs.img"),
assert(package_extract_file("m9kefs1.img", "/tmp/m9kefs1.img"),
run_program("/tmp/flash_image", "/dev/block/mmcblk0p13", "/tmp/m9kefs1.img"),
assert(package_extract_file("m9kefs2.img", "/tmp/m9kefs2.img"),
run_program("/tmp/flash_image", "/dev/block/mmcblk0p14", "/tmp/m9kefs2.img"),
assert(package_extract_file("m9kefs3.img", "/tmp/m9kefs3.img"),
run_program("/tmp/flash_image", "/dev/block/mmcblk0p15", "/tmp/m9kefs3.img"),
delete("/tmp/efs.img"));
delete("/tmp/m9kefs1.img"));
delete("/tmp/m9kefs2.img"));
delete("/tmp/m9kefs3.img"));
delete("/tmp/flash_image");
After the flash I got back my baseband :victory:
My IMEI has changed from null / null to a 0 / 00 this is not a problem over here, and my network is fully active and amazingly still UNLOCKED.
I would hopefully inject my original IMEI with Z3X box service if I couldn't repair over the QPST and other similar softwares.
Thanks all.
UPDATE:
I have added the EFS zip, this works confirm with i337 and i337m
But this does NOT work with i9505 (I would not advice to flash it on i9500)
Follow all the procedures before going for a flash.
Thanks to @Quasimodem for the original zip.
UPDATE Feb 24 2014: HOW TO RECOVER IMEI
Unfortunately I do not have the phone myself now, but here is success report of recoveing IMEI after flashing this EFS:
Ziida said:
Thanks! Flashing through TWRP didn't do it for me so I installed CWM tonight based on your suggestion and it's worked! My baseband became readable and my IMEI went from "null / null" to "0 / 00"
To anyone else coming into this thread: CWM was a bit of a hassle to install, so I had to use this guide (mind their typos...).
Anyhow, the most exciting part is after flashing the good Captain's EFS file my phone was recognized by QPST again!! I went ahead and flashed the AWS .qcn file from this thread, and now my IMEI number has returned!
I hope you have similar luck, dogmatism!

Yes pm me your imei and I'll try to edit my efs files... I'll pm you an untouched copy too if you want to have a crack at it...

I have also installed stock ROM. but it is as if nothing changed. :what:
I wonder if I should flash a custom recovery and format the system manually and then Odin flash the stock ROM.

That's not going to do anything for this particular issue. I'm about to zip up my backup and send it your way, and dig around inside the files myself. This is repairable somehow.

I have:

m9kefs2.img
m9kefs3.img
I will watch this for awhile, and see what happens. Just trying to figure out what you guys are trying to accomplish...carry on.
My suggestion is be careful with IMEI as if you let someone have your #, and at any point that person plugs in that # in his device and hits the network, you will get both devices blacklisted from the carrier. I am hoping you guys know this.
i have to first root then. give me some time.
I think you sent your efs via dropbox link, i have it downloaded already thanks.

[Q] Sim card not read. Imei and other stuff set to unkown

Hi guys.
I've rooted my phone then updated the room too crash.
After the room settled down, I manually reboot it after then persistent boot loops happened and the imei was also gone(I've tried to go to sretings as quick as possible). I tried re flashing the ROM but no avail.
Is there a workaround for this?
Thanks in advance guys.

Hi again
Sorry for the confusion. My phone crashed during office hours and can't think elaborate more.
The situation.
1. I came from Omega Rom v6. Decided to manually reboot because battery was draining like hell.
2. The samsung intro (samsung galaxy note 3 sm-9005 screen with the system message on the upper left) didn't show up with the said message.
3. Bootloop comenced.
4. Reflashed Omega hoping things would turn out ok. But no. My sim was not read and my interface buttons are not responding.
EDIT:
5. Then decided to flash new android os. Naming kitkat.
6. Bootloops are gone. And so is my IMEI and every other stuff found in that page.

[Q] Galaxy Note 3 (IMEI Lost) Need help

Hey Guys!
Firstly, I know this same thread has been made for other devices. Most of which have solutions, but these do not work for me. I really need your help with my problem!
The Problem: My GN3 has lost its IMEI, the EFS folder might have gotten corrupt somehow. But by a stroke of bad luck, the IMEI turned to unknown and no methods seem to solve this.
Thus far I have tried changing the IMEI with NV Tools and EFS Pro. None of which work, I tried generating a new file and flashing it on, that did also not help.
It was stock 4.4.2 Samsung, rooted. We sent it in to a service center, but since Knox now says 0x1 they want to charge us R3500 (~$300) to repair it.
Upon inspection, I noticed from my EFS folder that all files starting with 'nv' was gone. SO I copied these from my rooted Note 2 and placed them in the folder. Idea being that I could just change the IMEI using NV Tools, as it didn't work otherwise. This however did not work.
The only sollution I can think of, would be for someone to make a backup (using TWRP or CWM) of their EFS folder, then for me to restore it and then change the IMEI with NV Tools.
I promise I did not steal this phone, and it is not blacklisted or anything. Ill send any who might help me a picture of the IMEI on the back of the phone + the original box and the receipt if they doubt me.
I DON'T WANT YOUR IMEI NUMBER, but I need a full Note 3 EFS folder with the original files, so I can attempt to fix mine.
If anyone has a different solution I'm all ears, and up for anything.

I have done that, all it has done is increase the flash counter from 1 to 2. And remove my root. The EFS is broken (somehow) and I can't figure out how to fix it....

It was stock 4.4.2 Samsung, rooted. We sent it in to a service center, but since Knox now says 0x1 they want to charge us R3500 (~$300) to repair it.
Upon inspection, I noticed from my EFS folder that all files starting with 'nv' was gone. SO I copied these from my rooted Note 2 and placed them in the folder. Idea being that I could just change the IMEI using NV Tools, as it didn't work otherwise. This however did not work.
The only sollution I can think of, would be for someone to make a backup (using TWRP or CWM) of their EFS folder, then for me to restore it and then change the IMEI with NV Tools.
I promise I did not steal this phone, and it is not blacklisted or anything. Ill send any who might help me a picture of the IMEI on the back of the phone + the original box and the receipt if they doubt me.
I DON'T WANT YOUR IMEI NUMBER, but I need a full Note 3 EFS folder with the original files, so I can attempt to fix mine.
If anyone has a different solution I'm all ears, and up for anything.

Ok, what I found out as a solution was to delete EFS folder. Android will rebuild it! BUT: My EFS and Baseband are still gone. I reflashed stock (again) using Odin. No Dice. My NV_DATA, NV_CORE ect files are gone!
And IMEI isnt coming back.
If anyone has a spare EFS backup, or a script or something that i can flash to make my device have those files again I would appreciate it very much.

The following might be uotdated but no harm to try anyway(Can't copy the link so i copied everything)
1. Install Stock firmware via Odin, then re-run auto-root (to regain root of course)*
2. Install TWRP 2.6.3.2 via odin, reboot to recovery.
3. Do an "adb shell" when phone is in recovery mode to run commands via TWRP.
From the ADB shell: Wiped the EFS partition with the following command:
mke2fs /dev/block/mmcblk0p12*
mkdir /efs
mount -t ext4 /dev/block/mmcblk0p12 /efs
(the last two commands probably did nothing, but thats what I did anyway)
Do a factory reset, reboot system

Sorry @Hitman7987 but I'm new here but had the exact same problem you did.
I do not really understand the solution Rosli gave though. Could you help me out: point me to a post or explain here
What is an "adb shell" and how does one "do it"?
Thanks

I honestly can't remember, I think I just flashed TWRP and wiped the partitions he said to wipe. Then did the reboot.
Sorry for my lack of help, but I really can't remember the exact steps.

The rest are quite straight forward

Factory Mode ON

Ok, here's a Question.......
I have somehow gotten myself into factory mode on...this disables things on your phone like wifi, makes it very laggy ect, I need to change it back to user mode..
None of the things on google work, simply because there is no FactoryApp folder
My device is the N910F, if anyone can help, I would be most grateful as my phone is pretty much useless..
Thanks :good:
EDIT - I lost me EFS backup too, Im sure that would of done it...but there must be a way to reset it, Im also on a lollipop Rom, not sure thats why theres no factoryapp file

Best thing would be to Odin back to Stock, so probably back to 4.4.4, as for your EFS back up being lost, well so long as the EFS is still intact on the device going back to stock should be OK. From there you'll have to re-back up EFS etc.
Reason I say go back to Kitkat is because it seems to have no issues restoring back to KK atm, Lollipop ROM's are still a little picky at times.
Wow that sounds like quite a mess you've gotten yourself in mate What I'd probably do is copy the important files to my PC and then just use Odin to flash it back to factory FW.

Did you ever get a fix? I'm th opposite. I can run lollipop roms fine but even after factory restore in Odin my Tmob Note 4 still has the Factory Mode on issue as well. It's Because of the /efs file missing or corrupt so I'm told there should be a way to odin in the PIT file and the AP/AC and whatever other file there was, 4 total and use hemindal but I can't find anything on it for Note 4, only Note 3.......Anyone?

I tried, it doesn't work because it doesn't recreate the /efs folder or contents....Ive factory flashed stock image twice and issue just pops up again.
my efs directory is empty even with show invisibles on.....ugh

I fixed mine. I had an old backup from the current rom I'm running so just booted into TWRP and did a restore and selected the older backup and checked EFS ONLY and then rebooted and now it remembers wifi and no Factory Mode popping up so if you guys/gals have an older or current nandrpoid just restore the efs only from TWRP and you'll be good to go.! WOOT!!

good tip faslane ...thx man, u save alot of asses man
