Dear Friend,

Connect With PC In Dead Condition.

Open BP Flash Tool : bp_tool_emmc_download_v1.2.4 Or BP Software Update Tool_A21_A9+_EMMC_DownLoad_V1.1.3(Factory)

Select Firmware : BP_A21_592517_8550_WCDMA_V1025 Or A21_BP_592517_8550_WCDMA_V1026

Cellphone Will Power On, If You Have Virus Problem So You Need To Flash AP Part Also.
