I created this post because of my boot loop problem.
For those who are having the same problem with the Lenovo Ideapad A1, i didn't find any way to fix it through the forums neither anyone here was able to help me out, so i decided to go ahead and do a Factory Reset even if it erased my data.
I did it and it set my A1 to the default set up just like when i bought it. It deleted all the apps i installed but it didn't erase any of my files or folder (pictures, documents, videos, music) all was there, including the data folder for the apps i previously intalled.
So all i did was reinstall all the apps i had before and i had running just like before the boot loop.
So if you have the same problem, you could try doing the factory reset.
It worked for me. i hope it works for you!
