Xiaomi Note 6 Pro Stuck at boot after -Full erase before flash-

Elias

Hi every one, i have a Xiaomi Redmi Note 6 pro wich came with no baseband, no service menu even with Dev. Rom, so i tried with clear efs nvm and didnt worked, last thing i tried was to tick the -full erase before flash- option, since that time the phone didnt boot up anymore, i mean it stucks at the Xiaomi Logo..
I already tried to write another efs (modemst1, modemst2, fsg) from another phone in good condition but no succsses.. Im afraid that i messed up with security files from the phone so it can not boot now, i will apreciate any help from you guys.. thanks in advance.. here is the log from the last operation

Elias Hello,
Newest xiaomi devices implement Sign imei, so not possible to repair imei without auth by their server.
If device come with No Baseband, you can try at first to flash only modem firmware(NON-HLOS).
But, if you already try different firmware with no good result, even after restore the original nv backup, I guess the nv part already corrupt.
Maybe you can wait our next release update, it would be an option to repair Sign Imei.
Hopefully in next few weeks.

thanks for the replay.. so now, what i can do for the phone to start up at least again, i already tried to flash with authorized mi account, erased again efs, but the phone booted up again.

I'll answer to myself and is intended for public knowledge.
Most new Xiaomi model wont boot if emmc is erased or changed, i will stuck at boot logo, there are special firmware for emmc replacement, unfortunately those firmware are available to Authorized customer service only.
Unless someone can deny this information.
