But which box you use for write cert? As you said you use the uart cable. Tanks

Hello
You can use any FTDI interface you have.
if you don't have then you can buy one from gpg with cable set too.

Thank you for the credit ... I didn't wanted to release this stuff but I seen a lot people breaking their heads trying to wipe the EFS ... I also have another method with Odin just incase if the "Hidden Menu" gets patched by Samsung OTA

Here is a clean QCN N910A I you guys need it ..

@JUSMEJOSE whats the right way to write this QCN ? do I have to wipe efs then write qcn then cert ? or just directly ? any help ? thanks

After you write your "IMEI Cert" load the "QCN"/

Or back your own QCN before you wipe "EFS" using "QPST,z3x,Octopus" or any dongle/Box that supports "QCN" BackUP/Restore ....

you can't write by qpst may be cdma workshop work. Or z3x

**Note: Make sure is the correct model when loading the QCN , Because sometimes it will work and sometimes it wont!, I suggest if you just want to unlock just buy code "Online Server" this "IMEI cert" and "EFS: wipe is for Advanced users that that know what their doing, and if you have Unique "IMEI cert" ... Im not saying that your Dumb but you will save your self "Headaches" with your Customer ... **

Yes you can ... If you get "Forced Closed" you must be doing wrong ...

Yeah with CDMA workshop also ... If you know the "Memory Address" ;):D:cool:
