I've recently bought a Huawei M6 10.8". Unfortunately, it doesn't have Google Play (and the rest of the services). I'm trying to install it to it, tried to ask how to do it without unlocking the bootloader, didn't get an answer (probably because it's not possible). I've been reading and got mixed answers if the bootloader is unlocked I lose the warranty. I've read through the policy, didn't seem to find anything about that, so I assuming it's not the case. Either way without Google Play (and co.) the tablet is quite useless, I'll have to open the bootloader, get TWRP on and flash OpenGapps or similar.
I've been trying to follow this guide, but after issuing:
