Smile Tecno K7 Stuck on logo after format userdata

So have this set and was switched on but frozen,can reboot to recovery with vol+ and power.Tried wipe cache and would just freeze at wiping cache,force restart again then tried wipe,would freeze at formatting data.So put it on machine,set read boot info nicley and rebooted.I then used format data tab and phone was stuck on initial tecno with android at the bottom logo.Waited the 5 minutes and no change.

So force resetted it but would no longer go to recovery but was in a bootloop like would shpw supported API:3 then no command screen then supported API:3.Managed to reboot it and passed the first boot screen and it stuck on the second tecno logo screen.What could cause this team?

Below is the log of the format data tab:

In your case, can be emmc chip damaged, some sectors can be read only or unaccesible.
Userdata is encripted/decripted on each power on/power off and posible checksum of encripted userdata not math and phone go in bootloop.
