First we need to know more about your device.
Do "fastboot getvar all" and post the result here(remove sn,imei)

I'm not sure if this ruu is signed but you can give it a try.

So you ran the RUU, and the original question is no longer relevant?
You have the AT&T version M8, which is SIM locked by default. Was it SIM unlocked before at any time? It's not clear from what you have described so far.

(bootloader) security: on > nead to unlock
so your device may be LOCK or RELOCK > you need to UNLOCK again to Flash TWRP

Okay so i recently got an Htc One m8 from a friend. It's already rooted, but I dont know if it has a custom recovery or anything. Can someone fill me in on all the important things I have to know for custom recoveries and kernals and stuff like that. I have an At&t version btw.

I already tried to flash the stock recovery for VODAP203 (Vodafone FR).
Thanks for you help
TWRP made the main version disappear. Check the general section - collection of backups and firmwares. Read there and put 1+1 together. Take your bootloader number 3.16 and your cid vodap203 and match a backup from the list. My guess it starts with 1.12 or 1.54. Restore it and also flash back the matching stock recovery and then update
Thanks for your reply, I checked the files you said here : http://forum.xda-developers.com/showthread.php?t=2701376
but no one match with the bootloader or the cid number.
And what do you mean about : "Read there and put 1+1 together" ?

That was about the bootloader and cid. With those 2 you can determine the software number. Don't see your actual cid present but you can try it with the 161 backup
Take the 1.54.161 and try it with that one. No harm can be done in trying

Based on someone else experience (but on other version), reflashing firmware may be able to fix it.
Download 6.15.720.2 OTA.zip and extract out the firmware.zip - http://forum.xda-developers.com/showpost.php?p=65126875&postcount=2574
run these commands :
fastboot oem rebootRUU
fastboot flash zip firmware.zip
You'll see -
if failed : FAILED (remote: 90 hboot pre-update! please flush image again immediately)
repeat fastboot flash zip firmware.zip
after it says successful ..
fastboot reboot
then see whether the problem is fixed or not.
i have htc m8 lastr night i reset my mobile after unknown imei

Recovery won't load?

Hi Guys,
So basically I keep trying to put twrp recovery on my HTC One M8 and when I go for a new version of twrp and flash it on to my HTC it appears with "FAILED (remote:image error! (BootMagic check fail))", however when I put on an older version of twrp it works fine until I load up recovery where it stays on the boot up screen and won't go past that forcing me to force power off the phone. I have a standard HTC One M8 with Android 6.0.1 and the phone is "Unlocked" with S-ON, HBoot version is 3.19.0.0000.
Thank you for reading and I hope someone can help

No IMEI and no SIM Card after Bootloader Unlock

I unlocked the Bootloader via HTCDev and flashed TWRP + LineageOS 14.1 and now in Settings I can't see an IMEI no more and SIM card is not recognized. I haven't S-OFF the phone yet.
which variant of the m8 you have ?
los supporting all variants it's just weird you have issues
are you using a sprint device on gsm network ?? it's tricky to have this work
I have a t-mobile Germany device.
maybe your firmware is outdated
can you post the result of fastboot getvar all ( after removing serialno and imei )

it should work just fine
maybe you need to configure your APN for your carrier
It doesn't work. Still no signal
Try this as many have solved this problem by flashing the firmware.
Relock bootloader and install the fw_6.12.111.4.zip
https://forum.xda-developers.com/showpost.php?p=60218734&postcount=5
Then you can re-unlock again.
Thank you very much. It worked
