First method to unlock Samsung galaxy s7 edge and Samsung g s7 unlocking vie retrieving network unlock code from galaxy s7 OS.
Samsung galaxy s7 edge
sim locked then unlock code must be stored within android OS of Samsung g
s7. To recover network unlock code first
download any good file explorer or root explorer from the app store. This method cannot be used with sprint,
Verizon, bell and telus CDMA Samsung galaxy s7 edge unlocking. As there is no unlock
code used in cdma unlocking. This trick can only be used with GSM network
unlocking like at&t and t-mobile sim unlocking.
Also go to Samsung G s7 edge setting- about device- software info- tap 7 times build number. This
will open developer option. There is an option for enable USB debugging,
root explorer and mount file system then enable those options.
Install SU - superuser to root/
system / sbin,xbin and bin.
Here are the possible location where Samsung galaxy s7 sim unlock code and Samsung g s7 edge network
unlock code can be stored.
1) Browse the /root folder of s7
edge galaxy android and find the folder named carrier. Under carrier folder
there is a file name called property or build.Prop and APN config. So location
for unlock code for galaxy s7 edge is */carrier folder/. These are the files
where network information and sim network locking information are stored. If
you replace this file with unlocked version of files. Samsung galaxy s7 edge can be unlocked for free.
Carrier folder has all information about GSM sim network. For older galaxy
mobiles here is the way to find samsung galaxy sim network unlock code from Samsung
android OS. This method is only useful for previous version of Samsung galaxy
mobile. At&t t-mobile sprint cricket
sim carrier folder may have different name.
2)
There is EFS folder under */root
folder. This EFS folder have all information about galaxy s7 IMEI number,
sim network information, sim locking information and it also has NV data. NV
stand for Non Volatile memory. This file may content information about sim
locking code. So search for nvm_001, nvm_002 file name. And if you find such
file. Open those file with editor and look for network lock or sim lock
information. Rewrite of NV data can also
unlock Samsung g s7 edge smartphone. I have created separate post
for how to unlock Samsung mobile without unlock code. Go through that post, in
that post I have given detail about how to
get NV data option on Samsung galaxy mobile. EFS folder also contain
carrier folder which has hidden menu for Samsung galaxy s7 edge smartphone.
