help needed to flash lineage os 15.1 rom

I have a Micromax Canvas A1 with unlocked bootloader and TWRP 2.8 installed through fastboot. It seems I have no OS installed(I came to know through TWRP and bootloops). But I managed to install TWRP...I also managed to put the .zip file to root of SD CARD. But when I try to install zip through twrp...it shows failed error...this is the same case with stock rom .
Points to be noted
+) i have Unlocked bootloader
+)i have Twrp installed
+) Twrp shows unable to mount system and data
+) Unable to flash stock rom through SP Flash tool (stops at 6% ...Even though I tried 2-3 times)
Pls provide a solution to flash the Lineage OS 15.1 ROM...if not...stock rom will also do....
Here are the TWRP screen messages..

Mi8 bricked

Hello guys, i try to explain the problem.
I had Mi8 unlocked, then i download from xiaomi.eu the last release 8.8.30 and TWRP. I flash recovery in fastboot mode and flash rom in TWRP, in that momento the phone cant boot, stuck in loading screen.
Trying to solve I install MiFlash to flash a chinese stable rom, in that moment the screen turns off, my PC recognizes the phone and the MiFlash too but always black screen. I choose two pics, one shows like the PC recognizes the phone and the second pic shows the error i have now in MiFlash with black screen.

i have the same issue

Guys! Problem solved, i contact with s-unlock.com and in a few minutes the work was done and the phone its alive.

After flashing TWRP you could probably just have done a format data (where you need to confirm with yes) (so you get rid of the encryption, it's the issue why you can't boot), still in TWRP transferred the rom to phone and then flashed it and it would probably have booted fine.
But glad you got it running again.

Think you bricked your device.
Try flashing your stock rom to your phone.

Thanks for the advise, i flashed it with LineageOS and now its working fine

Bump

Despite i don't own this device, i can try helping:
you could try to get out of fastboot by pressing all of the hardware buttons (always works in my case) and the phone will attempt rebooting.
Not sure if this whole dm-verity disabling caused the device to go numb (i own one with dm-verity) and it gets a bit hard when i used to try and flash a different custom OS by disabling storage encryption.
Not even aware if this thing involves reflashing again the firmware, but i found a neat post that could disable dm-verity for every android device
Edit:
in case of struggle with reflashing stuff and start all from scratch, MTKClient can be of help
