i have buy a teclast x98 air III (M5C5 only android) and after flash bios 2.02 for dual boot my device dont boot but reboot with loop after the firs red logo.
i try to press vol+ + power but not "selection os boot" is displayed then try vol- and power but nothing .. i have only the DnX mode ..
i try to flash with MFT the mirek rom but i get this error message "Failed to execute fastboot -s Baytrail oem start_partitioning" and if try to stock firmware the error is different "no valid installer medium found"
the first time try to flash a mirek rom success but the same bootloop problem and now any flash rom i try return a error
now i flashed mirek rom and stock rom successfully but the same bootloop is present.. only see the red logo
i tryed with keyboard to enter on bios menu but i dont see any "boot option" or "boot override" for selection and if i change some setting and "save" anything is saved but all is default setting
I hope you can help
