How do I return to full stock? - One (M8) Q&A, Help & Troubleshooting

hello,
My Phone is HTC M8x
MID 0P6B11000
CID HTC__621
My bootloader is unlocked and I am S-On (can't do S-Off cos I don't have MasterCard)
I am currently running the 6.12.1540.4 version software of HTC Marshmallow
How can I return to Stock Lollipop?
I need that to get OTA to Marshmallow and get the latest firmware
Thanks

[Q] Can OTA downgrade firmware?

Hi,
I unlocked bootloader, installed TWRP and rooted my HTC One M8. Unfortunately, earlier I updated device to 2.22.401.5.
If I will restore 1.54.401.5 software, can OTA 1.54.401.5 -> 1.54.401.10 downgrade firmware from 2.22.401.5 to 1.54.401.10?
Refresh
S-On - No
S-Off - Yes
Is it possible to make S-OFF on 2.22.401.5 firmware without Sunshine?

Help with installing ARHD

Trying to install Android Revolution HD lolipop, i have tried installing it but it just gets stuck and reboots into recovery. I need newer firmware but i can't find anything that supports my model and cid. Any help would be appreciated. Or can i flash firmware that does not have my cid somehow ? What are my options?
TWRP 2.8.5.0
Current Firmware: 3.11.1700.5
S-OFF
0P6B12000
cidnum: CWS__001 AT&T
I think i figured it out:

Vomer's guide pretty much covers it. You can change your CID since you are s-off. And you can make it SuperCID 11111111, which allows you to flash firmware for any CID (SuperCID essentially "passes" any CID check).
You can also try the firmware for the US Dev Edition. Its Lollipop firmware, and intended to be used on AT&T's network:

Looks like you're running the GPe conversion. If so, you first need to get back to the Sense partition so follow the 'Back to Sense' thread in General and then flash the Sense-based ROM of your choice (along with matching FW package)

The latest is 6.12.1540.4
If you want to update, you can use 4.17.1540.9 RUU to get back to stock ROM then do OTA to Marshmallow 6.12.1540.4
Or you can use a TWRP 4.17.1540.9 nandroid backup and its stock recovery then do OTA to Marshmallow 6.12.1540.4 - you can read my thread on how to do that - http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
You can do these on S-On, no need S-Off

You only need s-off to flash an unsigned firmware, or firmware for another CID.

firmware update for MM support

hi, thanks for reading this
phone details:
version-main: 2.10.166.2
mid: 0PJA10000
cid: VODAP120
bootloader relocked
S-ON
i would like to update to firmware 3.35 for MM support,
i got a backup of the phone but no stock recovery hence no OTA updates (since i had to flash twrp to be able to backup in the first place ...).
couldnt find a RUU or stock recovery image that would work with my CID i a tried quiet a few EUROPE and VODAFONE zips
is there any other way than: purchasing sunshine to S-OFF -> change the CID-> flash firmware/custom RUU? if that is the only way to go which RUU should i use after CID change?
please advice, thank you
