To flash c72 using papua you need calculate bootkey keys,In my case I have

OTP imei :not recorded or incorrect

So to resolve that you need downgrade the phone to v <36

Hi,
You don't need to downgrade your phone to calculate SKEY and BKEY. Use Viper or BsReader midlets to calculate. Search on this forum "How to use". If you want to try to downgrade, you have the following options:
-download fullflash from http://rapidshare.com/files/95521020...ll_V16_lg4.rar and flash it (with X65 flasher).
-make firmware downgrade (check "Skip" Pre-Check and push red button). Download firmware from http://eh.student.utwente.nl/~landy/index.php?dir=C72/

...try first to calculate "Calc Skey + BootKey" (using papuautils). If this keys is calculated, click on "X65.ini" and copy this saved file in the X65flasher folder. Now you don't neded to make testpoint using x65flasher, appair your IMEI in the open phone option. Use it.
About the WinSwup, you don't need to make testpoint. Only "Skip" Pre-Check option and use the service cable.
