It doesn't matter if it's in a boot loop if you can enter preboot. Remake the cure firmware again after checking you are using the correct firmware matching your unit's HWID. There are two different HWIDs in 13xx, the more common 0972 which you have and 1104 [MTK chip].
So, to be empathic, if you can enter preboot the chances are 99% you can use cure fw to fix your unit. Give feedback of full details of what you've done and intending doing along with any error messages or results you get going forward, precisely follow the suggestions given and you should end up with a fully functioning unit finally.
Just don't make us guess at all, no tiny detail is unimportant.![]()
