This is an ATT version phone I rooted this phone a couple of days ago with TWRP. However, I had to use adb to enter fastboot as it would not go to fastboot using power/volume keys. Actually, it never shows a fastboot screen, even in adb, so it may have been going into fastboot all along and I just could not see it.
So, instead of leaving well enough alone, I RUU'ed (newest ATT version from HTC site) it to try to get fastboot to work normally (it still works, I just can't see it on screen). Now, I can't get rooted again. FWIW, I did make a backup with TWRP before RUU'ed. Regardless, there is nothing on this phone I need to keep, I just want to root it before I start using it.
Any help is greatly appreciated...
Here is my unlock sequence. Note what happens if I try to flash TWRP immediately after unlock. I have to CTRL C and Reboot phone.

Bad download then, see how the sizes of the file are different when you flash it again. At least the command is correct now. Re-download the recovery file and try again.

Still no luck, same error (see below). This worked flawless before I flashed the latest ATT RUU.
Is it possible phone is still not unlocked or would I be getting that far if it was still locked?
Question. This phone is AT&T (more details in getvar above) but at the end of the contract, AT&T sent me code to unlock the SIM. Now, the SIM I am using is on a T-Mobile MVNO (TING). Since they SIM unlocked the phone, would I be able to and would there be any advantage/risk to trying to flash the Stock RUU for HTC unlocked/developer. It is a higher software version than the ATT version I flashed (twice).

Any other ideas? I can't see bootloader screen, but it appears I can access and do all bootloader functions in adb.
I would really like to be able to eliminate locked bootloader as the issue, is there anything else I can flash or try that might let me know if bootloader is still locked. I can get results from getvar and fastboot devices.
I also have an image of the phone saved from TWRP before I flashed the RUU, but seems no way to get that image back. I am not opposed to purchasing S-off if that will for sure help me.
Try to flash a lower version of TWRP and see if that helps: https://dl.twrp.me/m8/twrp-2.8.7.0-m8.img.html

OK, lets try this a different way. IF one were to try to flash TWRP to M8 AND the bootloader was NOT UNLOCKED, what error message would one get?
Would there still be a response from adb getvar and fastboot devices IF the bootloader were locked?
Trying to eliminate potential issues one at a time
Is there a more appropriate forum for me to post the question?

Long Story a little bit shorter, on my HTC one M8, the error:

Was due to a locked bootloader. Because, for some reason I can't see the bootloader on my phone, I could not see the lock status, so I was having to do EVERYTHING via ADB. The problem was, when unlocking the bootloader there is screen on the phone that asks you to confirm yes or no if you want to unlock it. I could not see that screen and the instructions I was reading left that out (It was a good assumption that if one was trying to unlock one would know to say YES. LOL). So, I was missing that step. When I found that step, even though I could not see it on screen, I just blindly pushed volume down and then power to select. At that point it unlocked and allowed me to flash twrp 3.0.
Still do not know WHY I can't see the bootloader screen. I wonder if for some reason the colors are off in my bootloader screen and all the words are the same color as the background or it is trying to redirect that output somewhere else.
but at this point I am going to live with it as trying to fix it is what got me in here in the first place.
Hi,

The top post is in regards to getting signature verify fail message when flashing custom recovery. So I don't see how it's the "same problem".
Be careful about saying "same problem" without giving any specific information about your actual problem, or device details. From my experience, I've seen many dozens of times where folks say they have the "same problem" and when prompted for more info, we find there are many many differences.

Did the RUU flash successfully, or were there any error messages?
Also, please do fastboot getvar all, and post the results (delete IMEI and serial number before posting) so we can see more info about the phone.

This is normal and expected. You can't use adb when in bootloader. And you can't use fastboot and adb simultaneously. Meaning, when one works, the other will not work, by definition.
Fastboot = only works in bootloader fastboot mode
adb = only works within OS, or alternately will work in custom recovery TWRP
If you issue the command fastboot devices, you should find that it works.
It is also not clear what you are trying to use adb to do (what commands?).
Bought Japan Variant HTC 10,
S-off, Bootloader Unlocked.
[flashed TWRP once and did Backup.]<-yeah i did
Changed CID to US Unlocked one and RUUed Android 7.0
All went great at this point.
Then I tried to flash TWRP again and now i just can't boot into it.
flashing went smoothly, at leat log says;

AAAAAAAAAAAAAAAND I just can't boot into TWRP.
Phone just showing htc logo for a while and reboot to ROM.
So i tried fastboot boot twrp.img method, still not working.
download mode screen
Am I missing sth? like key combo to show twrp or bug at twrp 3.0.2.6?
I had the exact same problem, I solved it by flasing the twrp 3.0.3-0 unofficial version that you can find on the twrp recovery's thread
Edit: I don't know if this is the right way to do it, it worked for me but I'm new in the modding world and I'm not sure it will work for you too or if it's safe. Maybe is better to wait for someone that knows more than me.
solved
Since I did OTA from 2.28.617.8 to 2.38.617.6,
I googled and RUUed 2.38.617.6, not 2.28.617.8 from official HTC US hp.
and I flashed twrp 3.0.3.0 unofficial, instead of 3.0.2.6 official.
I don't know which one was critical, but everything went fluently.
Seems like 3.0.3.0 was the critical one.
Thx @fratorga100, for the reply.
I recently got a replacement HTC 10 unit from HTC. I am attempting to install TWRP on it, but am unable to.
I did the standard unlock method from HTCdev.com. Everything there worked fine and the device is unlocked.
I have downloaded multiple versions of the twrp.img but am having the same issue across the board. I can't figure out what is wrong, as I had no issues on my previous HTC 10 unit.

Everything seems like it's fine, but when I try to boot into bootloader and then recovery it gives me the htc, this build is intended for develpment purposes... screen and then goes directly into the rom never loading TWRP.
I can't figure this out, as I never had any issue before. My device is updated with the latest US version.
Can anyone help?
Thanks
I was having the exact same issue and was literally typing the same post as you when I saw yours.
I found this link with the unofficial TWRP builds and flashed 3.0.3.3. That finally got me into TWRP. You'll still see the gray HTC letters with the red disclaimer, but wait a few seconds and it should boot into recovery.
Hopefully that helps.

[SOLVED] Recent TWRP, CWM, and Philz recoveries all fail. Using an older (3.0.0.1) version of TWRP allows the HTC One A9 to successfully enter recovery.
I've tried installing both TWRP and CWM recovery. In both cases, ADB reports that I've successfully updated the partition. When I select "Boot to Recovery Mode" with CWM, I get the error "Failed to boot to Recovery Mode". When I select "Boot to Recovery Mode" with TWRP, it boots to normal, not recovery.
I'm using the most recent .img from both, for the HTC One A9. Here's what ADB reported:
