unlock i5700?

Can I unlock it for free?

There is a method but it is not realy useable because you loose your imei.
1) Root your phone
2) Use a root explorer of your choice and go into the efs folder
3) Make a backup of your "nv_data" file by copying it to your sd card ("sdcar" folder)
4) Delete the "nv_data" file in you efs folder.
5) Reboot.
6) Now it is unlocked but your imei is 00000000...
PS: Your phone will still work without a problem even with a zero imei. You can always go back by copying the backup file into the efs folder but then the lock will be there again.
Tested with 2.1 os.

Just wondering, will loosing your imei do any harm? I mean once we root & flash a custom Rom its not like we have any warrenty but will it ever effect the usage of the phone in anyway?

Please help...

[REF] Manually change "sales code" (CSC selection) when multi-CSC won't allow you to

[REF] Manually change "sales code" (CSC selection) when multi-CSC won't allow you to
I've recently been getting annoyed with how, whenever I updated a firmware, on first boot the phone would still look for an invalid CSC code, which I had "removed" from the phone.
For example, none of the XEU CSCs currently available will allow you to change to / from XEU as those CSCs don't include other options. ... so if you've manually set your CSC to XEE using the *#272*IMEI# trick; there's no way to get back to XEU.
The solution is as follows: (yes, you need root)
1) Ensure the product code in your nvram.bin file is set how you want it, in this case XEU. (it's in the file twice, once on it's own and once at the end of the "I9100LKA" string. Both those should be at the end of line 215 of the file)
2) (and this is the new bit) - there's another file on the phone which stores the "Sales Code" - its the file that tells the phone what CSC to look for on first boot after flashing a firmware. This file doesn't change unless you can successfully use the *#272*IMEI# trick!
2a) Using a file browser that has root privileges, navigate to /efs/imei/ then look for the file "mps_code.dat"
2b) Open this file as a text document (making sure you're mounted R/W) and edit the string to whatever you want (in this case XEU). Note, you should only put in the 3 letter code, not the rest of the product code.
2c) Save the file and reboot the phone. Hey presto you're on a different CSC!
(and I *think* this trick works to change CSC (without actually installing one, obviously), without wiping the /data partition.

wow great work

ok maybe it's just me but I cannot locate the nvram.bin file anywhere????
I'm on ke7 cf rooted and using script manager to browse system, could u direct me pls as I am running around in circles here.
I found efs/imei and that is xeu but i'm stuck on abr somewhere and it's causing me a few probs.

what and where is this "nvram.bin" file ? thanks

With all due respect sir..yes I have root..but still can't locate the nvram.bin file. I found the rest but as per my understanding is...I need to change the value in the nvram.bin file aswell to make all this work.
Thanks again for all the help.

My method on SGS1 was to use custom rom from rom kitchen open that and just change the required CSC folder and files with new folder and files zip back up and install .
Does not work yet on SGS 2 due to being unable to rezip and install custom roms .
Work around has just been to copy the relevant \CSC folder and two CSC files + SW conf file to phone deleting originals . Files have been ripped from original firmware nandroid backup .
Factory reset and all changed .

Ok dokie...thanks for the explanation.

No, because there is no "nvram.bin" inside the latest (-> KE2, KE7, KF1) stock firmwares!
And changing only "mps_code.dat" won't do the trick as this will only create a new "nv_data.bin" after next reboot.
And if you would delete this new "nv_data.bin" (hoping that the files will be recreated/replaced at next reboot, this worked with SGS like this) you will end up with NO ProductCode and an fake IMEI too! So you should be VERY careful modding anything inside of /efs!

I edited the nv data.bin as well from KOR to BTU is this not a wise thing to do on GS3?

your phone is in factory mode!
do this:
you must be rooted.
using root explorer or file explorer or what else, go to efs/imei folder, and make a file called "keystr" (without " ") (it is probably missing)
open "keystr" file and write "on" (without " "),save. set permission of the file (all ticked).
now open file "factorymode" in efs/factoryApp directory, it probabely says "off", change to "on" (yes "on" is the correct setting to turn it off), then save
reboot

[Q] HELP! Samsung Galaxy S5 Stuck In Factory Mode!

Hello Everyone.
So... I'll get right to the point here. My Galaxy S5 got stuck in factory mode. That day i was installing a bunch of ROMS. If you need a list of them, let me know.
I decided to go back to my old nandroid backup because I wanted to wait for a 4.4.4 version of the ROM i had found. However, I also got interested in installing a Custom Kernel, so I went ahead and installing Chronik Kernel cause I heard that it was really good. However, I forgot to wipe the cache and dalvik cache before installing the zip, so now I think it messed up my EFS partition, and am stuck in factory mode without WiFi and calling.
I have tried many methods involving the "FactoryApp" folder, but when I checked my phone to edit the text, the folder wasn't in the EFS folder. So I also knew that the Terminal Emulator option was out.
I even tried unrooting and re-installing the stock firmware and doing a factory reset, (I have a nandroid backup on computer) but even that didn't work. I can re-root if needed, but please someone help me, I really want to fix my phone soon. (Also I probably shouldn't have tried doing this on my vacation from home, oh well I am a really curious guy)

Help please!!
Someone please help me! I really don't know what to do! All that is in my EFS Folder is a bunch of APK files for apps i have installed and these files called: act_lock, react_lock and react.lock.bak. Someone please... I really want to get back on WiFi, also I am back from vacation, so I can use my Data plan to install things needed.

Is anyone going to help me?

Typically it is in a file efs/FactoryApp/factorymode.
Can you show your efs folder structure?

It looks like you have an invalid efs folder.
Did you make the imei backup? If so just restore it.
If you don't have imei backup, try reflashing full stock firmware.

Yes, it is not too weird as Samsung now does not store the IMEI in EFS partition. It does store in another 2-3 partitions (these partitions are vary from model to model).
EFS partition does not contain the IMEI. It contain the S/N, WiFi and Bluetooth MAC addresses, etc...
Please do the following things:
1- Install Phone INFO ★Samsung★ app and look for the IMEI and S/N (in the DEVICE ID section), and compare them with the IMEI and S/N on the sticker behind the battery. Are they the same?
2- Create a file with a name 'factorymode' on the sdcard, open it, input 'ON' and then save it. Navigate to the efs folder, create the folder with a name 'FactoryApp' (case sensitive). Finally move the file 'factorymode' you have created above to that folder. Reboot the phone to see if the problem still persists?

Yes, as I have said, the efs folder does not contain the imei. However it does contain the S/N.
What did you mean by 'serial number isnt'? The S/N in Phone INFO app is still in valid format? Or it is zero or empty? Can you PM me that S/N (in Phone INFO app)?
Regarding creating folder, make sure your file explorer app has been grant root permission. And try to move/delete some APK files (in efs folder) to free space.

I9500 Factory Mode Is On

I have a problem with my i9500... after getting it fixed by a service center i got a Factory Mode is on massage and then my wifi turned off... I tried everything that i found on the web and learnt everything related to efs folder that I could have find but with no luck...
I guess its something about efs directory permissions... is there any advice there from you guys about this problem maybe a list of ownership/permissions for every file/folder in efs folder could do the trick
many thanks in advence!!!
BTW i have efs backup but its only the folder so i think its might be lacking the right permissions or ownership for the files inside...

Is your phone rooted? If yes then follow this:
1-using RootExplorer/ES FileExplorer navigate to efs/FactoryApp/ and search for "factorymode"
2 - open it with text editor and change OFF to ON and save it.
3-restart.
All the best!

Thanks for the replay...
I managed to fix the issue by deleting all efs folder and then restoring it from a backup i had... then did factory reset (all the needed wipes) and vuoala got back to user mode...
