(12-09-2016, 02:12 PM)sherman I've been on along thing ooo... Inoticed before flashing twro to the phone through adb you must unlock bootloader. And after unlocking the phone formats thereby formatting everything in the phone including the imei number again. So an to ask if Ican use sp flash tool to just download the twrp into the phone and then backup my nvram.?

yes, you can use spft to flash back TWRP
BUT since the device has already been wiped while trying to unlock the bootloader, you'll still have to check and be sure that all nvram related items (imei, wifi, bluetooth etc) are in order before backing up.
(13-09-2016, 02:38 PM)sherman Actually they are not in order after unlocking the bootloader. Now I downgraded to 5.1 version and I saw partition backup application. I rewrote my imei to sim1 and sim2 then I rebooted my phone the imei is backup,then I opened my partition backup app and backup the current secro nvram and nvramdata partition. I will upgrade it back to 6.0 marshmallow, Root it and reinstall partition backup app then restore n see what happens at last.
