Redmi Permanent Bootloader Unlock Function Updated to MTK Meta Utility V52 No Relock Free Tool
MTK META Utility V52:
– I noticed a lot of people strangling to unlock bootloader for this model (Redmi 6A (cactus)
– Added Permanent Bootloader Unlock for Redmi 6A (cactus).
– Note : The Bootloader will be permanently unlocked after performing this operation,
the reason is we enable eMMC permanent write protect flag to SECCFG area
using the MTK CPU and SBrom Crypto driver to prevent BL re-lock after boot-up.
– We set a small check flag to ensure the device model is (Redmi 6A) the method is risky,
so please try to operate with any different model code.
– Added eMMC/UFS health check from BootROM mode.
– The method uses DA setup handler to init the IC and dump
EMMC/UFS check statically implemented in the DA as well to detect HW faults, could work even in dead DRAM case
& please don’t try to operate this method with non-original OEM devices such as Infinix/Tecno,
the device might stuck at brom mode after health check and will need to disconnect battery to get brom mode working again.
– Added Dump and parse EXT_CSD registers via BootROM mode (implanted in eMMC/UFS health check function).
– Added Huawei Y9A FRL-L22 Force BRom mode from Upgrade Mode.
– Added Huawei Y9A FRL-L22 Exit BRom mode.
