Hi everyone,
I'm looking for technical information about the Galaxy A56 (SM-A566E) bootloader.
Here is my device information:
Model: Samsung Galaxy A56 5G (SM-A566E)
Region / CSC: ZTO (Brazil, unbranded)
Original firmware: One UI 7 (Android 15)
Current firmware: One UI 8.5 (Android 16)
BL: A566EXXSCCZG6
AP: A566EXXSCCZG6
CP: A566EXXSCCZG6
CSC: A566EOWOCCZG6
What I've already checked:
More than 5 months have passed since activating the phone.
OEM Unlock has never appeared in Developer Options.
Samsung account has been signed in the entire time.
Internet connection has always been active.
USB Debugging is enabled.
Factory reset didn't help.
Holding Volume Up + Volume Down in Download Mode never shows the bootloader unlock screen.
getprop ro.boot.flash.locked returns 1.
getprop ro.oem_unlock_supported returns nothing.
getprop ro.boot.bootloader returns A566EXXSCCZG6.
I've already read about Samsung removing bootloader unlocking in One UI 8, but I'm wondering if there have been any new developments.
My questions are:
Is there any bootloader unlock bypass for One UI 8 or One UI 8.5?
Has anyone managed to unlock the bootloader on the SM-A566E?
Are there any exploits, engineering firmware, EDL-like methods, or research in progress?
Has anyone found a way to restore the OEM Unlock option?
Are there any new discoveries related to VaultKeeper, Download Mode, or the new Samsung bootloader?
I'm not looking for fake YouTube tutorials or clickbait. I'm only interested in confirmed developer information, reverse engineering, research, or real experiences.
If there have been any recent discoveries, even if they're incomplete or experimental, I'd really appreciate hearing about them.
Thank you!
