Blackview bv9700pro

Hi, after flashing firmware to wipe all, I have everytime a red flag at the upper right cornet TEE: GOOGLE:

Please, I need some help. I'm completely lost.

Best regards,

I did receive from Blackview support the apk and manual, but I do have some questions.

I've been trying to do it, but when I click to start, this ask me to put the IMEI's which is ok, becouse I have them, but this ask me too the MEID (14/15 digits) wich I don't know.

I guess In MD1_DB, I must put "MDDB_InfoCustomAppSrcP_MT6771_S00_MOLY_LR12A_R3_MP_V58_5_1_ulwctg_n.EDB"
and in AP_DB i must put "APDB_MT6771_S01__W1917"

Please, somebody can help!
