My phone was working fine except it had null IMEI and NVRAM WARNING ERR in wifi, so I followed this video by Hovatek
I had a NVRam backup so I did the following:
1. created an empty folder on my pc, placed the nvram file & android scatter file in it.
2. edited the scatter file just like the video.
3. tried to flash using sp flash tool but immediately got status_preloader_invalid error.

and since then my phone won't boot again! I have a Tecno Spark 5 Air KD6, rooted with Magisk and TWRP installed too.

u most have a valid preloader file before u can do this , because if u do so without valid preloader your phone will go blank

but take the battery out or be table volume down while plugging in till I get detected and I can flash preloader before commencing anything

My phone has an internal battery that can't be removed, I tried plugging the phone into pc with down volume botton pressed but the pc can't recognize the device and says it's malfunctioning (like in the photo) even though the drivers worked just fine before the last flash attempt...

Just bought a small screwdriver for the phone and unplugged the battery, now it boots just fine, but I still have the issue presented in the video by Hovatek, NVRAM Warning in wifi and null IMEI for SIM cards.. any ideas? thanks in andvance.

I already wrote the device model in the question, anyway I managed to fix the error and write IMEI with MauiMETA 
couldn't write WiFi and Bluetooth mac addresses with SN Writer but they still work fine so I will just ignore that. Thanks for help ^^

This was because of the interruption. Incase of next time,  See https://www.hovatek.com/forum/thread-808.html
Holding volume down + Power button for about a minute resolves such.
