Alcatel POP C7 7041x Hard Brick. Buggy CPU, Enable DRAM Failed.

Hi, I have 2 pieces of OT7041X. I had bigger order for changing lang in this phones. I made more than 10 pieces without problem by flashing them with firmware which I read from another phone with desired lang. Even flashing with preloader didn’t kill this 10.
Unfortunately no luck with next part of this order. First 2 pieces died by flashing preloader. Now I see only Enable DRAM Failed, no matter which SPFT version or firmware.
Any news about this bug to revive it?
