[Q] Lost EFS data Need Galaxy Note II from shoppingsquare.com.au Owner

Hello Friends,
I am in big problem at the moment. I flashed new roms (geek will know it)couple of times.But since last week my phone does not recognise my sim card or get any network and its IMEI also got currupted and I don't have backup of my EFS folder. I found out that the it may restore it to normal by installing factory stock rom. But for that I need somebody who have got Samsung Galaxy Note II from shoppingsquare.com.au in last October to March. So that i can download appropriate country's stock rom as it is grey import phone.
I need below firmware info, which you can get in Settings and About device
Baseband Version
Build Number
Thanks in advanced.

@Bajanman sorry but that guide is useless for the LTE Note 2 variants. Look for guides from the LTE Note 2 or the North American SGS3 as your main starting points to try and solve this. (My T889V LTE guide has some links to those.)
One method I'd like to hear reports about is the reboot nvrestore one, I've seen it discussed mostly on a Verizon SGS3 thread, but nothing IMHO says it wouldn't be relevant for the HSPA/LTE versions either.
Edit: The EFS and other related partitions are of a significantly different layout between the dual-core SGS3 and the LTE Note 2 or GT-I9305. adb reboot nvrestore doesn't seem to do anything on our devices.
Good luck,
Darkshado

hey i didn't find anything...i've heard that there's some custom roms that contains EFs backup that can solve my problem is this true ? if so can anybody give me a link for one of those roms ? thank you

Try to flash with odin the stock rom that you got your note 2 with. It happened to me once where i flashed something and lost my imei. I didnt backup or anything. After i flashed the stock and unrooted my phone my imei reappeared and my phone worked again. BTW it was a att note 2. I found the rom somewhere at this forum. No rom contain you Efs i think(could be wrong) but each phone has it own imei.

N7105 factory mode

Hi guys, i seriously need help here. Please refer to attached screenshot.
I came here after flashing sokp 4.2.2 rom, and it prompted me an error saying encryption was unsuccessful. After which, i wasnt able to use my phone since then.
I tried to flash stock rom, and I end up with this. Please dont tell me to search the forums because Ive been to them countless times. I suppose this is a efs issue, because baseband and imei are unknown and I do not have a backup for it. Tried with the writing tool for imei, doesnt work as well.
Pls ask me for any info u might need/i missed out to help with this issue.

I think it's in the efs folder, you have to use a root browser and edit factory mode to off instead of on. It's been a long time since I saw factory mode so I'm not 100%

Thanks for your reply. But even if I off factory mode, will the baseband and imei be unknown?

I'm not sure but if it doesn't the 2 things that might be worth trying are, emergency firmware recovery with kies or mskips toolkit has a rescue package but I think you have to go to skipsoft.net now as the thread was closed
Sent from my GT-N7105 using Tapatalk

It's current value is "OFF"...u have to write "ON"...i know it sounds weird but that is the value. Amd if u don't have any previous back up of EFS then there's nothing u can do at home to bring it back. Same thing happened to mine and i got it repaired from a local shop for cheap...they used z3x box...the problem is my IMEI is correct and network works fine...but everytime i flash a ROM i have to take it to the shop and get the modem patched or else it doesn't connect to network. So go to Samsung service centre and get it fixed by them...they'll charge u more but their fix is permanent.

Alright, it seems like i have a backup of the efs, bt the nv_data.bin file is not included, and i read on other threads that this file is responsible for the imei and all? This backup is dated in aug2013, but it doesnt help in restoring my phone because the efs pro software doesnt see this as a backup file. Im actually looking for one of the thread that actually taught how to edit the nv_data.bin file, but no luck till date.

This thread might help

is it safe to flash the file that is intended for i9300? i dare not do that in case it doesnt work coz is different models.

ok my phone's all fixed up now. If anyone is interested to know, samsung kies original firmware helped.

try flashing your official firmware through Odin. other users solve their imei problem by doing that. see also if you can access engineering mode with that official firmware.

lets wait for others specially those who are expert in android for some advice. I'm just an ordinary security guard so i can't help you much with your problem. what i have suggested you from my previous post was the last thing I did when my phone finally worked. for 4 days i been searching for solution because i also have an IMEI problem. i flash back to official rom, flash patched modem, flash other roms to no avail until such time when my phone doesn't boot because of broken partition :laugh:. if you still have warranty restore it back. if you're already out of warranty and you have money, you can it send it to service center.
P.S.
you can also try this if you have courage. i was able to make some secret codes work but i have'nt tried if it works with engineering mode by modifying hiddenmenu in /efs/carrier/hiddenmenu. use efs explorer to open hiddenmenu and change it to ON.save it and restart your phone and see if engineering mode work. remember that you have to be in official firmware and also rooted to do this. if its not working then you'll just have to wait for a much better solutions from devs.

Same question
I have the same problem, as owner of the thread. Any help?

STILL NOOO HELP
Please me, i have lost my IMEI saying NULL / NULL and im getting not registered on error. I have not backed up ESF folder as well.
Struggling from last 5 days to fix it up. some how i got Modem_N7100XXDMG1 and flashed. After that i have got some fake IMEI.
Tried flashing STOCK ROM 4.4.2, but still no luck.
Read on some forum that MODEM of 4.1.2 or J.B 4.3 resolves this issue but when i try to downgrade from 4.4.2 to 4.3 via ODIN it straight away shows FAILS in RED
IM using Note N7100 K.K.4.4.2
PLEASE PLEASE PLEASE HELP ME.

If you have no backup and the stock ROM did not work, they you are pretty much out of luck. I had a backup but the IMEI didn't come back until I flashed a different modem. I used modem_XXDME4.
If you know what your IMEI number was, then there are ways to write that number directly into the phone. Need to send the phone to someone that has the hardware though. You can buy it yourself but it costs about the same as a motherboard replacement. Youtube "N7100 Android 4 3 imei repair z3x" to see what I'm talking about.
If you don't know the number, don't have a backup, then you'll have to change the motherboard.

You can find your IMEI number on the back of your phone though.. Pull out the battery, it's printed above your device's serial number.

I have my IMEI, i just wanted the solution through software can i change my IMEI or i have to go service center that would cost about Rs. 5000 minimum.
modem_XXDME4 is S3 modem, how can i flash it on note 2 N7100.
PLEASE HELP

@dineshdotcom2000 have you tried different modem? I had the same problem like yours and flashing my region's modem didn't solve the problem. I flashed European modem - modem_XXDME4 - and the dummy IMEI changed back to the original. Maybe you should give it a try.
Here is the link https://www.dropbox.com/s/5mrtz2c6s29ibxt/modem_XXDME4__.zip
I flashed the exact same file on my device and it worked. Good luck :good:

Any way to do it???

Find a service in india that has a z3x box. They can write the IMEI directly without swapping the motherboard.

just search, a few days ago there was the same problem solved probably in Q&A thread
