[Samsung Galaxy S7 Edge Questions and Answers] Matty1993:
For all those whom have lost your imei or serial number on your S7 if you dont have the box or the backing has been replaced,

If you remove the backing to the phone there is actually a sticker on the battery with a gold tab at the bottom of the phone that contains your imei number and also serial number.

Samsungs print the imei number on the devices 4 times 1st in ☆#06# 2nd is lasered onto the backing at the bottom 3rd is the sticker atached to the backing when first purchased & 4th is the sticker under the backing of the phone located on the battery at the bottom,

If you have lost your imei & not serial number also and cannot retreive it with stock firmware installation then use Z3X 29.8 cracked with the loader open the Z3x tool go to repair enter the imei printed on the sticker and click the repair button your phone will restart and your imei will be back you must have your phone rooted for Z3x to work however i have tested this repair on android 6.0,7.0 & 8.0 with Z3x cracked it changes the imei every time,

Dont try to change the imei to another different not matched to your phone and patch certificate as it will not work patch certificate only works in 6.0 if you change it to another go to ☆#0011# you will see at the bottom the imei say NG when it should say ok so domt change the imei and try to patch cert you can also set the sim count to 2 with 2 imei numbers also on the G930F to make it a dual sim as i have inspected plenty of G930F board and they all have printed on them G930F/G930FD/G930W8 i have also inspected the sim slots and they do indeed have the pins required already built in to the reader the only thing that is needed to change to dual sim is the dual sim card sim slot and set 2 imei number in the box and set sim count to 2 and voila z3x does the rest. Pls note though you cannot change the serial number on them with z3x thus serial number is what linked to the modem HW ID to allow the phone onto the carrier networks the best ive been able to do with android 7.0 & 8.0 on the V2 firmware is change the imei and when putting a sim card in getting the option for VOLTE however wont register on network and imei is still NG instead of OK in ☆#0011#

Anyway enough ranting of mine hope this can help someone and apologies for reply to an old thread guys im really baked and really bored buisness is slow today haha :P sunday in australia...... trying to figure out FRP removal on G930F V2 bootloaders also turns out if you extract the firmware with winrar then extract the AP file with 7zip then go to meta data inside that is a file called FOTA.zip well samsung have added there very own password to protect such file on the archive took a while but fotatest1234 isnt a very secure password samsung once extracted enter and find the build.prop enter that and theres all the information to edit the settings to enable ADB by default ive done that packed it all back up but just cant get it to flash ive used .imgTO.tar to convert the file to an MD5 that odin will accept and i get the message leave CS... which means odin has loaded the file and has found no error in the binary but as soon as i hit start odin will crash mabe it has something to do with odin and the edited build.prop or the way im packing the firmware back up anyone know what im doing wrong ? Any help greatly appreciated while im here
