Acer B3-A30 FRP Reset with CM2MTK (MT8163) Hello, friends! Is it possible to remove frp of Acer B3-A30 MT8163 Tablet with Chinese Miracle 2 MTK. I tried connecting the tablet while holding different key combinations but i get two different errors: [DA_ERROR] : SECURITYBOOT_BOOT_NOT_ACCEPTED and: [DA_ERROR] : DRAM Configure failed! I reckon that i should unlock the bootloader but its not possible via fastboot option :(. Any ideas? Thank you in advance!!! |
Thanks for success report :) continue like this :) |
