DTPro Redmi 9c imei repair steps, please

[seyken]

Need step by step instuctions for Redmi 9C(Angelica) imei repair.
Authorize successful, also write eng firmware but after eng firmware phone dead and only restarts on mtk vcom port.
Flashed back original firmware and get phone back to live...
What is the proper ordet to do imei repair? Authorize and then still on mediatek tab Access->Login->Format/Whipe ? Or? Then repair in meta mode or?
I'm a bit confused in what exact order and on what tabs to perform the required operations...

if the phone does not turn on after the Engineer's writing - it is an unsupported version!
"please replace preloader"
-After engineer write > Wipe NV for repair IMEI
