According to the log this doesn't look to be a known brand but it's
probably a Chinese clone of a phone in market already if you dont mind you
can dump the phone and have a back up and prot try to look around who might
have a device exactly like yours his dump will revive your phone challenge
is these clones don't have factory firmware they dnt have support so good
luck

Using mtkclient, unlocking the bootloader is smooth until DaHandler, where
it throws "unknown seccfg partition header". I think some of my attempts to
unbrick the phone might have ended up bricking it further, but I want to
try repair it. My parents already still have their old phones, so they're
not in a rush, but I'm out of ideas. Previous searches don't yield much
information about this error.

I did find something online similar to the bootleg ROM on the phone on NeedROM. I've downloaded the files, but I'm still missing some. |
