Keeping root, taking custom ROM/Kernel off.
I've done some research and I realise I just need to flash the .290 baseband to get the kernel off, but how would I go about flashing the stock rom/firmware and not lose root?
I'm using Purestock and doomlord Kernel. My reasons for taking these off is that my phone is blighted with random resets, battery drainage at an unbelievable rate, etc. I have the Xperia Z1 C6903
