M8 stuck in bootloop(?)

Hey guys,
First off, any help here would be more than appreciated as I am at my wits' end.
So, i shall try and inform you guys as much as I can and hope it suffices. My M8 seems to be stuck in a bootloop. I can get to the bootloader (hboot & fastboot) and that's about it. I tried to flash a new recovery and kernel through fastboot but that doesn't seem to help either. My phone has been unlocked a long time ago but never had any problems until this suddenly happened.
Here is my oem info:

PS- It is also interesting to note that when my phone is stuck on the white HTC screen, i can hear message notifications and such implying that the phone is still running ( I even mirrored my phone to the pc using USB and I can see my home screen on my laptop but just the HTC screen on the phone.
Thanks a ton in advance

Were you trying to flash anything (such as a custom ROM) to make this happen? If not, why would changing the recovery make a difference? If yes, what did you flash?
Phone was on stock or custom ROM when this started to happen?
Do you have a nandroid backup you can restore?
Also, newer versions of TWRP won't work with your (ancient) hboot, so depending on what TWRP build you flashed, you can just be adding to the problem.

No, I wasn't trying to flash anything which is what baffles me more. My phone just froze all of a sudden and I had to use Power+Volume Up to reboot and it hasn't been starting up ever since.
I'm current;y running a custom ROM (skydragon if I remember well).
The last significant change I remember making was giving the "Clean Master" app accessibility permissions through the settings. Idk why it didn't just ask me to do it through SuperUser there.

As I asked before:
Do you have a nandroid backup you can restore?
If so, try to restore that backup.
Otherwise, try to re-flash the custom ROM.
What version TWRP are you currently on?

Surprise Boot Loop - Can't fix via RUU :(

Hi,
My european One M8 suddenly rebooted a few days ago while sitting idly on my desk next to me, for no apparent reason. It went straight into a boot loop where it vibrates, turns screen on then shows the green HTC logo. Screen would then go blank, then back to HTC logo again, over and over. I ran the battery down, restarted on AC and the problem was fixed, only to happen again an hour later. Now I can't boot into the OS, but can get to bootloader and stock recovery menus using button combos. The phone is the unlocked version, and is S-OFF using sunshine about a year ago while I played around with custom roms. Since then I've gone back to stock firmware/OS using RUU, and updated OTA to the latest android a few weeks ago. Phone worked fine since then.
I've tried using the following RUU + a factory reset, but the problem persists:
0P6BIMG_M8_UL_M60_SENSE70_MR_HTC_Europe_6.12.401.4_Radio_1.29.214500021.12G_20.72.4196t.01_release_464360_signed.zip
I've been desperately looking around for pointers and re-locked my bootloader, then tried RUU again. Still didn't cure the problem, and may well have been a bad idea I guess, as now I can't seem to unlock it again.
Here's the output from "fastboot getvar all":

Desperate: HTC Reboot Hell, even recovery

First of all thanks for anyone who can help me.
I'm quite desperate after spending countless hours on XDA trying to get my phone to work.
I received the phone (international HTC one M8) in a somewhat broken state and I am trying to fix it.
Originally the phone had a 4.4 rom on it which caused the phone to reboot constantly, I couldn't get the rom to update either so I decided to flash it to Marshmallow.
Set S-off, I flashed TWRP and installed the latest Skydragon rom. Wifi wasn't working though so I flashed ruu firmware 6.12.401.4b. The rom worked, Wifi worked, but only downside, it only booted while being charged with a cable, and the sudden reboots started occurring again. So I think the battery might be shotty too. Anyway, I got a device tree warning too, so I reflashed a different Ruu, reboots started occurring even when trying to get to recovery. So I went back to the 6x ruu, tried to flash Skydragon again and then I spiraled into real trouble. Each time I tried to flash a rom, the phone reboots while installing. I even tried the MeID changer to make sure it fits with the firmware.
Long story short, the reboots got worse, I can't get into recovery without rebooting. If I run recovery over fastboot, I get into the recovery, but it reboots when I try to flash anything. I also tried Phil's revovery but same problem.
I can get into fastboot, hboot and bootloader just fine though.
Any help is greatly appreciated.

Need more info to proceed. Please do a fastboot getvar all, and post the results (delete IMEI and serial number before posting).

Sure Thing! Thanks!

It is indeed an M8_UL which is the GSM/Int version.
However version-mics shows: XF SHIP S-OFF
M8_UL_XF is something I have heard of before on a forum (few pages back, there's a thread with a similar case).
Anyway, an ordinary M8_UL will show 'PVT SHIP S-OFF'.
XF is either a 'different' variant or some type of engineer/prototype device.
What do you think @redpoint73?

Here is the getvar all from my M8.
Notice the version-misc.

Thanks @murtaza02, I finally got the damn thing to work because of your comment I realized my CID was bogus and wasn't corresponding with the MID, so I fixed that using fastboot, flashed the EU 6x FUU and the corresponding RUU (https://www.androidfilehost.com/?fid=24369303960687057). And behold, It booted into Marshmellow!!
Now though, the phone still keeps shutting down (not even rebooting) and won't start android without being plugged in. Could this be software related at all? Getvar says the battery is good and when it craps out, (most often when trying to enable WIFI) it shows the battery charging just fine. I still see the device tree warning on boot btw.

As I said, yours is XF and a normal M8 is PVT.
Your device will accept a MM firmware, however there may be a SLIGHT difference in partition/partition sizes hence the device tree error and irregular behavior.
Your CID was not bogus, it was just SuperCID which is used to bypass the CID check during an RUU/FUU flash.
I'm still trying to figure out why (and how) yours is different.

I don't know much about the XF variant, either. But I recall @ckpv5 pointing out the difference to an XF user a week or 2 ago. So maybe @ckpv5 can jump in and give some advice here?

@redpoint73, Thanks but I fear @ckpv5 might not have any more info to go on. I found his post where he referred to the XF variant. He said it's quite possible a US variant, definitely has different partitioning than the PVT version, but didn't know more. I've also seen posts of people suggesting it's a Canadian version.
I bought it on Aliexpress if that is any lead. But in all honestly, I'm really starting to worry I have an expensive paperweight.
One more potential clue, the Alie page suggests the phone only has WCDMA, no LTE, could that be a lead? Ow and one more clue, the model number on the back of the phone is: OP6B100x

Can you link the post, so I can take a look? I remember reading the postat the time, but the details are foggy; and maybe there is something useful there.

Help** HTC M8 Stuck on Boot Screen

I have been reading and trying to rectify the issue of my HTC M8 being stuck at bootloader from most helpful articles here but I am finding myself back to square one.
The issue is that my phone crashed suddenly and through bootloader I have chosen factory reset probably 100 times and the phone just keeps getting stuck so I have concluded that the ROM is corrupted. Now as I will require to flash the ROM again I am stuck as to how to go about it.
I have followed many articles and downloaded ABD and have familiarized myself with fast boot.
If one of you could please assist me in the applicable ROM and what process I should follow I will be most grateful.

Ditto
Funny enough my M8 (never rooted) did something very similar.
I used it before sleeping whilst the battery was ultra low, and it just ran out of juice rather than a proper shutdown.
In the morning I charged it and got the same "stuck on boot screen" when I powered it up.
A factory reset didn't work either.
Fortunately, still under warranty so returned to EE for a repair.
P.S. See also http://forum.xda-developers.com/htc-one-m8/help/phone-loses-settings-apps-battery-dies-t3375980 for other issues when phone battery dies.

stuck at bootloop and recovery shuts off

Hi all,
My HTC One M8 is rooted with TWRP. I was having issues with it, so I decided to wipe it to see if that would help . However, it's now stuck in a bootloop, and when i try to get to recovery it turns off, or get a computer to recognize it.

What problems were you having exactly (before you wiped)?
What partitions did you wipe?

The phone is not turning on, it boot for a 2-3 sec that the logo shows up then it turned off, i've tried Volume UP+Volume Down+power method , Volume UP+power,but that's not working,also i tried factory reset ,then flashed RUU, the phone turned on for few minutes, while i was plugging it then it turned off and back to the previous problem. I think it's a battery problem but i don't know cuz it showed that is charged +90% and still not turning on.

It does look like battery issue. And I believe you wiped the OS so it can't boot when connected to charger.
Had same experience on my M7, only can switch on when plugged to charger (I didn't wipe anything so OS was still there and able to boot).

I installed a RUU from HTC's website and it took a few minutes to turn off and not switching on again
