Install CyanogenMod on my Honor5x L21-C432B140 Lollipop

[greendra8]

Hello,

I have a rooted Honor5x L21-C432B140 Lollipop with TWRP recovery, and I would like to install CyanogenMod 13 on it. I understand that I need to get my phone to use Marshmellow, and to do this I need stock recovery, which as I said I have TWRP instead. The problem is I am unsure which files I need, and what to do with them, and I am scared of bricking my phone.

Can someone please guide me in the right direction of what I need to do? I've looked through most of the Honor5x stock recovery threads and all their replies, yet I am still a little confused as there are no step-by-step instructions for a noob like me to use.

Thanks!

You need to flash stock MM with adb first ....go to in still CM 13 and gapps ...cleen and reboot

I'm also having issues installing CM on my L21-C432B140. I followed this guide (except I got the firmware from here here) to update the firmware to L21-C432B340, and then I installed the cyanogenmod (newest available nightly, installed via TWRP), and I'm now stuck in a reboot loop. I've rooted my other phones without issues, but I'm completely stumped here. Any ideas?

Edit: There also appears to be no way for me to downgrade. As I understand it, I need to flash stock recovery that's compatible with my firmware, but I can't find stock recovery for B340.
Edit2: Never mind, I'm currently downgrading to B140 again with B140 recovery, though I'm not sure it really helps me get any closer to installing cyanogenmod.
Edit3: So I finally managed to get to B330 (I couldn't go from B340->B330 for some reason, I had to downgrade to B140 before I could try B330), and cyanogenmod successfully boots now!

For reference, I used this guide to update my firmware to B330 (I found the B330 firmware here, as the guide doesn't offer a link for B330 firmware for my model). Then I installed the latest nightly CM via TWRP.
