Can't backup H815 - no partion detected error code 0x8000010a (LAF_ERROR_ACCESS_DEN

Hi ,

I read about SALT and it seems to be great tool. unfortunately it do not work well for me. I've attempted to update my phone to nougat and I've try to create backup but it failed. Later on I've found out that no partition was detected on the phone. The following happened :

- SALT installed on UBUNTU 17.04 - with minor issues that were solved

- Phone detected automatically

- Phone can be rebooted by SALT

- Error during backup

Log file is attached bellow.

Phone was delivered with Android 5.1 Updated to Marshallow via LG Bridge No root nor boot loader unlocked. After upgrade to Marshallow shows Warning massage after boot "Current version is not available for user. Can't find matched cust for NT-code mmx/mnc[],subset[]" , This messages is one of the reasons for attempting to flash Nougat, second one is battery life.

I'm looking for the following help. Waht steps need to be taken to backup the device and update it to Nougat v29a.

Can you please help ?
