I have Lenovo vibe K5 device and its running on Lollipop 5.1, for some reasons i want to downgrade it into Kitkat, So is it safe to downgrade higher end device into lower version of android if yes, i need compatible Kitkat OS for this device?

  • While asking us to find what you need us off-topic, it's generally safe to downgrade, should you find an appropriate, tested firmware. – Grimoire Nov 9 '16 at 9:04
  • Unless in very, very rare cases, it's impossible to go below a phone's initial factory firmware version, even with custom ROMs. – Andy Yan Nov 9 '16 at 9:37
