I have the M8 on Verizon. I'm S-Off, and am running the latest OTA firmware with a custom ROM based on the OTA.
Can anyone provide me some guidance on downgrading back to Kitkat? Is it possible? Is it as simple as flashing an earlier firmware and ROM? Or do I need to so something more substantial like an RUU? Thanks!

Go into one of my ruu threads that has the version you want. Flash the hboot first and then reboot the bootloader. Then flash the full ruu
The RUU threads don't appear to have the hboot to flash. Are the ones listed in the following thread what you were thinking of?

Thanks for pointing me in the right direction. I appreciate it.

Hi this is my first android phone, so I want to make sure I do this right.
Do I need to relock my bootloader after unlocking it to run 1.85 ruu?
If yes what am I actually upgrading in this step? If not, I can just flash 4.0.4/2.20 clean rom 4.5 after I have unlocked the bootloader?
Would the steps be like this?
1. 1 click change CID
2. Unlock from HTCdev
3. Flash TWRP recovery
4. Flash ROM?
Thanks!
Yep. If you're rooted then you have the right procedure. Skip 1.85
I believe that the only things that remain untouched by rooting, unlocking, and loading a custom rom are the radio (need to flash separately) and hboot (untouchable until we get s-off). (Someone correct me if I'm wrong here.)
I RUU'd to 1.82 when I unlocked but haven't done anything else since.
The newest roms incorporate the latest software versions. You don't want to update hboot to the latest version because they've change the security.
Thanks.
Should I flash the newer radio too? I can't seem to find it.

I would start with the one that matches your rom. You may feel like experimenting with others, as people have reported different results with different combinations. I am using the 2.20 radio with a 2.23-based rom.
Stock rooted 2.2, hboot 1.14, bootloader unlocked, S-Off, TWRP 2.3.3
I'm going to update to a newer ROM (Scott's CleanROM maybe, I like Sense) and I'd like to get the latest firmware and it seems that the easiest way to do that is to just run an RUU once rather than flashing multiple zips.
I've not run an RUU before so I'm a bit unclear what it does. I know it returns the phone to "stock" but some of the ancillary details aren't clear. Will it relock my bootloader? (Do I need to relock it before running the RUU?) Will it overwrite my recovery?
Should I run the latest RUU (3.18) before flashing a new ROM to get the lasted radios and other firmware? Or should I worry about that stuff after a new ROM? If I don't update the firmware and just flash a 4.1/4.2 ROM will that cause issues or instability?
No you don't need to relock sence you are s-off yes it will overwrite your recovery so after it is done you will need to fastboot a recovery with s-off you can run any ruu but I would recommend the newest one if you are going to run jb roms but you will need to downgrade your touchscreen firmware if you use aosp roms and older version of twrp there is a thread for that in original development

You want to flash a tmobile ruu, there's a dedicated thread which stores all ruus.
I don't remember if you need to relock before using the ruu, be sure to check that out.

I know it. He must be relocked unless he's s-off
Hey guys i'm fairly new to the one x and i've done some reading, i've rooted, unlocked the bootloader and s-off i just have a couple of questions.
I see for aosp roms that you have to update the ruu to 3.18 how exactly do i do that? What would happen if i didn't update to the latest ruu and flashed the aosp rom anyway? I'm guess like status 7 recovery error?
and would the unlock, root and s-off stay? also, is it safe to ruu?
For aosp roms do you have to downgrade the touchpanel firmware?
Sorry for all the questions but coming from an s3 this stuff can get to be a lot and i just want to make sure i'm doing everything correctly.

Download the 3.18 RUU here. Put your phone into fastboot mode and connect to pc. Run the exe file. It's that simple. Just make sure no other programs are running, and screen saver/hibernation are disabled. If you don't do the RUU first, the ROMs will not boot.
Your unlocked bootloader and s-off status will survive the process. You will just need to flash TWRP recovery again.
You don't need to downgrade your ts firmware for the latest aosp ROMs. If you want to run an older aosp ROM, then yes you do.

Slightly more in depth than other firmware/radio questions.
I'm coming from a Sprint HTC M8 and will be getting a Verizon HTC M8.
On Sprint, we had several firmware updates already, which we had to flash in order, otherwise we may miss something not included in the newest firmware.
On sprint, there was modified firmware including everything BUT hboot, boot, and recovery. Do we have a thread like this on the VZ HTC M8 forum? I saw "New firmware/boot.img/ota nag removal for s-off" but I couldn't really understand where the newest firmware was.
I understand how to flash via fastboot. So if anyone can help point me into the right direction to obtain these fastboot firmware files in order. Or.. if is not necessary to obtain these in order, just the latest modified firmware set?
Thank you!
This is the thread. We only have the newest firmware which is here. Is you are on the old stuff with the old radios like I was, you can soff, flash recovery, root, rom, then fast boot flash this. You want the one that says. Nobootimg.firmware. that will be the newest firmware and radios. http://forum.xda-developers.com/showthread.php?t=2723159
