Thank you very much again anycallmongolia.
Short tested on my S8600...
I can now flash M410KKRLF2_M410KKTFLF2_KTF...
As FFS I have taken from XXKJC...
Second test... M410 Boot with complete XXKJC...
Short tested... seems to work...
Next test... if these Bootfiles also work with M410S Firmware...
I think yes... if you wrote M410S BootFiles...
Sideeffect for S8600...
No WiFi... reason should be other/different Hardware...
Anyway...
S8600 Boot is locked only for S8600 apps_compressed... and failed with M410 apps_compressed.bin flashing...
Also short tested... if I can flash back to S8600 Boot...
Seems to work...
But my S8600 is JTAG before... maybe unsecured...
Best Regards
