I search the internet, but can not find any solutions.
System won't booting, locked FRP and locked bootloader. If i push the power button it's just booting to eRecovery. Fastboot mode and Recovery also available.
Bootloader can not unlockable, because system won't booting, so I can not enable "OEM unlock" and "USB Debugging" options.
Update
k. My theory is, if I buying credits for DC-Unlocker, and unlock (temporary) the bootloader, I flash the TWRP again. After that I want to a probe to flash the extracted boot.img, recovery.img, etc, what is HWMT want, to unbrick the phone. My plan is, to chose "unbrick" option in HWMT and all IMG files, what i'm extracted from OREO update.app and HWMT point to need to unbrick. Is this is a workable method, or just wasting my time and credits?
Or other idea to use DC-Phoenix and flash the nougat rom and thats it. But the question is the Phoenix and the service rom repartitioning the phone, and after that the phone coming back to life, or totally bricking, if i not flashing back the oreo?
Please, somebody confirm.
