I ran windows_fastboot_first_install_with_data_format.bat and received this respponse:-
Pressing return closes the cmd window.
The device reported has an ARMv7 Processor not the Qualcomm 888+ claimed in the settings.
It is a custom build version
alps-mp-o1.mp1-V1-164_k80hd.bsp.fwv.512m_P15
This would explain why it is so slow.
Anyone know how to get a ROM for it?
