Hello,
After updating, the M8 doesn't start, no access to bootloader, no access to recovery.
The bootloader is locked and the security is at s-on.
The charging led flashes in bright red color, when is connected to PC or to its charger.
Windows 7 recognizes it as : "Relink HS-USB QDloader 9008"
I need helps.
Thank you.

Based on your model, you could ask for the eMMC partition back-up from someone and restore it.

I am a recent new owner of the M8. How would one restore an emmc partition backup? I am used to TWRP and wiping system, data and the two cache options...can see no legit way to wipe whole phone and replace all emmc.

I am looking in my dev/block folder and I see a lot of extra files in two folders, which are also apparent partitions. I have access to the back up of these via the partition apps, but I don't think you would want them as my phone has been restored from exterior lollipop nandroid created for its model number.

Has OP the adb and fastboot installed? How would one restore a full phone, in case I can find a perfect one for the model and cid I have here?

*I am also have just looked thru these mmcblk0p block partition files.and found where it says security on. Any idea if I can change to s-off by simply unpacking this g in Ubuntu and write off instead of on, and repack and restore?

I love this phone. It is the pinnacle of android, it just is rotten cause these many many problems. But if you seek you wont find a more luxurious phone in its natural state, be that 4.4.2 or 5.0.1 it is a cadilac of phones.

You can't achieve s-off by what ever you said here
and you can't access some partitions while your device s-on
and you can't flash un signed .zip to s-on device
