EFS help

Hello,
if anybody is able to share his EFS, please share it. I've tried modifying many "nv_data.bin" sample files but I couldn't get the IMEI to show something in any case. CVXCVX tried to repair my phone with his tools but still, no success.
I desperately need to fix my N7000 so please try to help somehow. For more info, please read the thread from my signature.

It works for me!

It seems that app won't work if your EFS is lost without a backup. I haven't tried it though.

Wrong Section
Bother this section is for Development section, Please post query, help and other questions in Q&A section.

this can only be repaired with a special JTAG,same that can fix soft bricks.this jtag can rewrite the imei.dont try other methods,this is the only one working.start looking for a service with this tool.here in romania costs about 10 euros....
Sent via N7000 from Asylum CM 10.1, madness at it's finest!

Thread owner should have mentioned that he bought a new eMMC chip and had it soldered on the MB (he hints at his project where this was discussed).
So all the normal possible solutions didn't work.
So maybe something went wrong when soldering.
Or if using a new eMMC chip on a Samsung board this needs some special "initialization" of the chip.
Or each chip has an hard coded IMEI inside, so that using backups or the polish repair with the old IMEI won't work.
(Added an answer here because I think the thread soon will moved to Q&A)

Have you tried the method described in this thread? Hidden Menu enabler tool + IMEI restore method

My technician mentioned that JTAG may be the only solution but I don't know... I'll try Adam's method first.

just find an early rom which has efs. img and flash through odin. It will give you what you need, except for original emei. That you can get Samsung or Polish way
edit, finding that rom will be difficult, but its out there
edit here it is
http://www.sammobile.com/forum/showthread.php?t=3136
It will change your csc, but you can change that by flashing the csc file of your rom of choice, then the *#272*youremei# dial. Note do this on safe kernel only

I have tried installing a 2.3.6 ROM but I still had no IMEI. Maybe the ROM didn't had efs file like the one you've mentioned. I'll try it so thanks anyways...

yeah flash efs file after flashing the rom separately. Set clear efs to yes.
all at own risk
let me know how it goes

BUMP

IMEI , Serial have been change to FAKE , and now i am unable to register to network

i can see that the problem because of my serial number and imei have been changed to fake (00000) or (360000000) after ROM installation , so now i am unable to registder to any mobile network
any help ?

Nothing except returning it or restoring the backed up efs folder that you should have made. Samsung is known for this issue.

you can try this

note I have never done it so take it with a grain of salt.

Be very careful with things like this. Messing with the IMEI is illegal in most places in the world and only the OEM has the rights to do anything with it.

if i returning it they will know that i am missing with device and the warranty is void right ?

bro i already told you i my rom thread, do not blame rom for you mistake, Rom does not effect IEMI or other stuff. Before blaming please learn some basics how rom/modem/kernel works

Well see that is where you maybe wrong. Flashing the device has everything to do with what happened.
Samsung devices have a history of doing this if the scripts are not set up properly. (main reason all real developers stopped working on Samsung devices.)
My advise is to back up your efs partition for the next time it happens from flashing a rom.

This is just a reminder, because I see someone reply threads on it
Said to modify the IMEI
Samsung mobile phone now
If you modify the IMEI
Or cancel the network lock through the BOX
Can meet a trouble.
That is DRK damage
This is forcing some users to upgrade or restore the factory Settings
Stay on the page of samsung LOGO
Part of the mobile phone can be solved by flash the kernel
But this is not a perfect solution
So, after missing IMEI must careful operation

i agree, many users have flashed the rom and no one had this problem, i have written script by myself and i believe it has nothing to do with other than /system. I always advice users to make backup, its much better to have backup than finding solutions

That is just the thing with Samsung devices. It doesn't always happen but can happen to people from flashing roms. Mainly Samsung roms. As they are the only ones that make the partition erasable when messing with the system partition. Samsung has been working on ways to prevent people from flashing roms. Again this is why most big developers walked away from Samsung and refuse to support their devices.
If I was you I would put a disclaimer on your thread to backup the efs partition. (this should be standard on all Samsung rom threads)
As for you writing the script yourself. After looking at your post history I would advise you to hit up some of the Samsung devs and talk to them.

Guys
i dont blame anyone ,but this is just what happened , i flashed VENOM and DRKetan Roms without having this problem at all , i dont know may be the issue on my device

It recovers Hard bricked boot loop ?
I was using the latest camera fix build of lineage os 7.1.2 from 2weeks on sprout 4 mtk6582 but suddenly every app starts force stop yesterday night and when i restarted the phone it hangs on lineage os loading screen. then i tried to boot into recovery mode to flash lineage rom again but the recovery was also not working . The i tried to flash the stock lollipop rom for spice dream uno using sp tools and that also didnt worked and the phone goes to bootloop i.e when connected to pc using usb cable it connects and disconnects each second. Please someone help if you can. The phone doesnt even show any screen nor fastboot mode or recovery , totally black screen. Please tell any solution to install the stock rom or lineage rom. If this app can help repair my android one sprout 4 then please help me.

Doesn't do much if anything.
You need ROOT already before you can "backup" the ROM. So those trying to get the ROM so you can root are going to be disappointed.
Then something funny happens when you use the uninstall available through the start menu. A program restore.exe gets quarantined by my anti-virus.
My advice, forget it.

It is possible to backup some without root. I have done so with a Qualcomm 8917 soc based phone with QPST.
Good looking out on this app. Who knows what restore.exe could be. Maybe some kind of packed advertising malware that came with his installer he used. Usually common on stuff like this so creator of installer and even person using it receives $ everything from installs to impression views etc.

nvram warning err = 0x02 on blu R1 HD

Hey guys! It's me again! I've just solved my imei problem, thanks to mrmazak, now I solved it, I've noticed that I have another problem... When I get into the wifi settings it gaves me this message: nvram warning err = 0x02 like an available network and this change my mac adress anytime I restart the phone....
I've been reading and the problem is caused by flashing (like I did) with SPFT in format all option....
Can anyone make a back up (with trwp) of the nvram files of the blu R1 HD and attach it to this thread to restore the information?
I hope you can help me!

Sorry but posting nvram from my phone would share my serial number and imei with the whole internet and I don't want to have my numbers band from my carrier. I know I'm over concerned. I will be working on changing the numbers and making a generic backup when my phone cones back from repair next week.

i dont have access to the phone to make twrp backup but here are the files copied with miracle box. And restore-able with either sp flash tool or miracle.
nvram and nvdata
you will need to rename them your scatter file "file_name:" and/ or change the "is_download: true"
temporary links. will expire 12-1-2016

you still need to use maui meta to get your own imei back after this.

Well man! You need edl maybe. But for that also you need to have backup beforehand. Check some tuts if you can or send your device nubia maybe. There is tutorial on xda somewhere for recoverying xda........!
