In second method we unlock lg v10 by generating sim network unlock pin for free. And I also explain how to generate sim network unlock pin for lg v10 t-mobile.                                        By above second method you can unlock lg v10 all models including at&t lg v10 h900 space black opel blue, unlock Verizon lg v10 vs990 luxe white, unlock t-mobile lg v10 h901bk space black, unlock lra lg v10 rs987, lg v10 h960 unlock, unlock lg v10 f600s – k – l, lg v10 dual sim h961n unlock and lg v10 dual sim 962 unlock. It also unlocks lg v10 h903/ h904 / h908 / h909.Why you need to unlock lg v10 smartphone                                          You have bought at&t t-mobile lg v10 with sim locked. Now you have two working sim card and you want to use those sim to lg v10 dual sim or you want to use another sim to your lg v10 android. When you enter new sim to lg v10 on your lg screen you get message that network locked sim card inserted, wrong sim card, invalid sim card unlock your phone, phone restricted enter phone restriction code, contact service provider to unlock lg v10. Now to use all gsm sim on your lg v10 you need to unlock lg v10 phone with sim network unlock code.                                             Before continuing to two different methods for lg v10 unlock. I give you some tricks to recover network unlock code/ sim unlock code from your lg v10 mobile. When you mobile locked it’s unlock code must be within its android os file system. So first download any file explorer of lg v10, lg bridge also a good file explorer but I am not sure it can go deep into file system.                                      First go to lg v10 setting and enable root explorer and enable mount file system and also allow su superuser. Now search inside root folder there is an efs folder under efs folder find nvdata file. Nv data is a non volatile memory which contain all information about your gsm sim network. It may possible that you can find network locking code inside nv data file. So remove that code and unlock your lg v10. Also search inside root/carrier folder, root/system, system/bin folder for carrierlock file or networklock file or simlock file. If you find any such file that has hidden unlock code in hexadecimal. So open those files with hexa editor and calculate your unlock code. It is not necessary that such file always exist inside your lg v10 this is just one trick. First method to unlock lg v10 at&t , tmobile without sim network unlock code.                                      This is only applicable to European version of lg v10 h960a android m unlocking. but if you are from other countries like united states of America, united kingdom, middle east eventhough you can try for this if you get unlock.bin file after registration then you are eligible for v10 unlocking.

Cellphone got freezed when it has roaming lock or when you have tried 5 or 10 unlocking attempt and mobile got hard locked.                                              Now after you get lg v10 sim network unlock code, insert any sim to lg v10. It ask for sim network unlock pin – unlocking attempt 1 of 10 unlock or dismiss. That means you have maximum 10 unlock attempt.                             Now enter correct sim network unlock pin for your lg v10 which is of 16 digits.  Normally you should use nck code and tap on unlock.  If your mobile is successfully unlocked you get message that sim network unlock successful.                                But if you get the message that sim network unlock unsuccessful then enter service provider unlock code – spck and many time bell, tenus and fido require both network unlock code and service provider unlock code. So first enter nck code of lg v10 and then enter spck code for lg v10.   I hope above lg v10 unlocking method help you to unlock all your lg v10 models.
