Hello.
Is seret.bin somehow encrypted?
Load file updater.bin to address 0x27C00000.

String addres OK, but code ARM looks pretty weird.
Has anyone analyzed the SERET code ?

What processor will work on SPI memory ?
Previously based on the 8051 and now?

iirc its not but secos is.
the problem w/ seret is how to f***ing start it:)
check onboot, must be triggered through some serial command stored in micom

That's why the code SERET in IDA is stupid, inconsistent.

Running SERET is not a problem.
Problem is decompile ....

New IDA and problem resolved the.
