you can run Linux on 3.55, if you find that unsuitable, you can downgrade back to 3.15.
Yellow Dog Linux 6.1, works on 3.55, 6.2 doesn't, you can check here what runs and what does not:

Also check this:

If you find the 3.55 version of OtherOS not suitable, you can downgrade back to 3.15 using this method:
