If you use custom da, not need to tick "bypass security" button.

I am using da from firmware I got on needrom

**orbita** · 07-22-2021, 15:15

Problem come from unsupported by exe flash id.
Try to load in exe preloader or firmware(not need to flash , just load) and execute opperation again.
It must work.

Also will be good if you will provide debug log with security bypass opperation.
Will need to check why exe give this error on security bypass.
This will help to fix problem and add feature support for this phones.

I'am asked for debug log not exe log, exe log you posted already before.
Provide please debug log.

To open backup location, you can press in exe button called "open backup location"
In this way will be more easy to find needed files.

soctia · 07-24-2021, 01:52

check this file for the info

**orbita** · 07-24-2021, 06:44

Hi.
I'am not see in this log any info about preloader initialisation.
Need to tick debug log checkbox, execute process, and after get debug log.
If you will get debug log before executing process, will not be usefull.

Contact me please by skype, will be more easy and fast to solve in this way.
