If Huawei Y3II LUA-L03 mobile dies while trying to root despite bootloader being locked, then the only solution is to restore it through custom DA file. In such cases, specific tools like SP MDT or QGDP also ask for DA file. In the absence of this file, the tools do not work because they cannot pass partition verification. DA file bypasses bootloader and gives full access to the tool.
Huawei Y3II LUA-L03 If during the repair of the mobile, the error "PMT changed for the ROM" appears, it means that there is a partition table mismatch. In such a case, it is necessary to go into full flash or format + download mode, which is not possible without the DA file. This file helps in accepting the new partition layout so that the functionality of the mobile can be restored.
