You do it wrong ... cannot use ADB for flashing hboot.zip/firmware.zip
See this guide : http://forum.xda-developers.com/htc-one-m8/general/vomerguides-m8-bootldr-unlock-s-off-t2800727
Basic thing is :
boot to bootloader/fastboot
then
fastboot reboot-bootloader --> to confirm the usb connection is good
fastboot oem rebootRUU --> to put the device in RUU mode
fastboot flash zip hboot.zip --> flashing the hboot
if failed : FAILED (remote: 90 hboot pre-update! please flush image again immediately)
repeat fastboot flash zip hboot.zip
fastboot reboot-bootloader

[Q] Unroot HTC One M8 Dual SIM

Hi, I have an HTC One M8 Dual SIM which I managed to root and s-off. I need to get this back to stock but am having some problems.
At the moment my phone is as follows:
Software Status: Official
***LOCKED***
M8_DUGL PVT SHIP S-OFF
CID-HTC__032
HBOOT-3.19.0.0000
OS-3.33.401.6
I have TWRP v2.8.4.0 installed as well
I have looked at the following thread http://forum.xda-developers.com/showthread.php?t=2735235 and managed to get the phone back to Software Status: Official and ***LOCKED*** I think but not managed to get S-ON or unrooted.
I have found firmware 3.33.401.6 for the M8 but not managed to find the actual stock OS.
Can someone point me in the right direction of what I need to do now?
This is the first time I have tried to unroot a device so sorry for anything I am missing from this post.
Thanks.

1. Do NOT S-ON unless the phone is 100% stock (and even then I wouldn't bother)
2. Flash the RUU in here - https://drive.google.com/file/d/0B17smFr95pleb3dJVDZVZTFfUEU/

Thanks. I have downloaded and run and get the error "ERROR [130]: MODEL ID ERROR"
I followed the previous guide and think I may have used the wrong recovery image as the guide doesn't mention Dual SIM. So, I have downloaded recovery_1.54.401.10.img from here http://forum.xda-developers.com/showthread.php?t=2701376 and tried "fastboot flash recovery recovery_1.54.401.10.img" but get the following error:
sending 'recovery' (15236 KB)... OKAY
writing 'recovery'... FAILnot allowed
FAILED (remote: not allowed)
Execution time is 1(s)
Not sure if the recovery image is the problem or not however.
Any suggestions?
Thanks.

If you've relocked the bootloader it won't work. If you're getting the Model ID error it means you've changed your MID at some point. Can you connect your phone in fastboot and post the results of fastboot getvar all (leave out your IMEI and S/N)

Back to being unlocked now by following htconeroot com again. After this, I have now been able to run the command "fastboot flash recovery recovery_1.54.401.10.img" to remove TWRP.
I have tried running the RUU EXE again but get the same issue. Is there anything you can suggest to get this fixed?
Thanks for the help.

Well, you've go the right Model ID, so do this...before we start make sure the RUU I linked to is named ruu.zip (not ruu.zip.zip!) and that you have htc_fastboot in the same location (if you don't have htc_fastboot you can get it here - https://drive.google.com/file/d/0B8L4pkbzdlR3eTlJSjdKVEdHX1U/). Also make sure you've relocked the bootloader using fastboot oem lock
1. Connect phone in fastboot mode
2. Run fastboot oem rebootRUU to get into RUU mode
3. Open a command window in the location where the RUU and htc_fastboot are
4. Type htc_fastboot flash zip ruu.zip
5. Wait for it to finish
If you get any errors please post them up

With "fastboot oem lock" I received the following, however after a reboot of the phone it is showing as *** RELOCKED ***:

Hmmmm, I'm not sure. Never had an issue doing it before but never used the Dual-SIM model. Can't see it being any different, though

I appreciate the help.
Do you have a link to stock recovery for the Dual SIM M8 as not sure that is 100% at the moment - when I press on RECOVERY it just goes back to the FASTBOOT menu.
Thanks.

I don't, no. I've been trying to see if anyone has the OTA cause you can pull it from that but the RUU is encrypted so can't be pulled without decrypting the RUU (which I don't know how to do)

There's your answer right there. You need to change MID to one that is supported by the GPE RUU. Looks like you've already changed your CID to one that works with the GPE RUU. But you need to change CID and MID.

OK I will try

adb commands dont work in fastboot mode, you need to flash the latest version of twrp boot into it and then use the adb commands if your unsure of what to do and dont want to furher damage your phone i can help you over teamviewer, changing your mid is risky if your not sure and can damage your device badly any wrong mistake and its game over.

adb commands will only work while booted in OS or custom recovery. That is what the previous post (Post #6 above) was talking about.

The photo in your first post indicates your bootloader is relocked. Did you unlock it again?
If its still relocked, custom recovery will never flash properly.

i fix the problem over teamviewer red point, what i did was edit the model id in the zip from the google play stock rooted rom to match his and flash it, then unlock his bootloader with adb and change both mid and cid to google play, his phone was stuck at the htc logo black screen that fix it.

Since you're S-ON, you will not be able to flash RUUs or firmware below your current ROM version. You can however restore twrp backups of Lollipop ROMs which work fine with your current 6.12 Marshmallow firmware. Otherwise, you can use twrp to flash any custom ROM based on marshmallow & lollipop.
Here's a link to stock marshmallow RUU (6.12.401.4) in zip format, which you should flash from bootloader.

I flash the twrp's recovery. I can access to it but when I try to go to install the zip file, twrp refuse to install it with "Zip file is corrupt". I double check md5 sum and they seems to be correct =( .
I also try to flash it with fastboot, just in case, and no result but with a different error: "(bootloader) zip header checking... FAILED (remote: 32 header error) "

You don't flash RUUs with TWRP, you flash them with fastboot in RUU mode. Which you seemed to know based on your top post, so I'm not sure why you tried to flash with TWRP this time.

You need to relock your bootloader to RUU with s-on.
Command: fastboot oem lock

I'm not sure which way you want to go, but:
1. To flash the RUU zip file:
A. You need to put it at the root of your SD CARD and rename it to 0P6BIMG.zip
B. Turn your phone off, then start it into bootloader.
C. Follow the instructions in RED to flash. You will lose all data as the RUU will format all partitions.
2. To install a custom ROM or restore a twrp-specific backup, use TWRP's install function, or restore function respectively.
Cheers

I'm not sure what RUUs you have tried to flash, but this is the last RUU version for your model (T-Mo Germany)
You can flash it with fastboot commands in RUU mode, or you can flash it via the SD card method.
The SD card method is easiest. Rename the .zip by deleting everything in the name of it except for 0P6BIMG (and .zip of course), put it onto your extSD, and boot to bootloader. The rest is pretty much automatic.
Note that since you are S-On, you will have to relock your bootloader first with either method. The command for that is fastboot oem lock
Good luck!

Very helpful thread. Wanted to ask for help here, but already solved the issue

HTC m8 phone keeps booting into fastboot mode

hello,
after root my phone
every time i try to put it in recovery mode it goes back to fastboot mode ..
even if i tried to flash a recovery on it , it would boot to fastboot mode
even when trying to install a official htc software update it just boots into fastboot ..
now i want to get it back to stock..
please help me !!

Need more info.
What version SuperSU? What version TWRP?
What "official update" file did you use? Was it an OTA or an RUU (list the exact file name)?
Also, do fastoboot getvar all, and post the results (delete IMEI and serial number before posting).

In addition to the fastboot output, I asked 4 questions, none of which you answered.
You have the M8 eye, not the "standard" M8. Far as I can tell (not many folks on xda have the "eye") you need a special version of TWRP for this version. You can try the right version TWRP, and flash SUperSU again, see if that helps. No idea if this version TWRP will work on not (can't personally vouch for it): https://forum.xda-developers.com/htc-one-m8/general/m8-eye-recovery-root-t3159648
Depending on what you did to the phone by flashing the wrong TWRP, it's hard to tell what the proper way to proceed.

hi
can i have stock recovery download link in that phone pls

I have a similar issue, but with a standard M8
£10 off ebay, so not expecting ,much (also means no known history) . 1 week old noob reading here and flashing phones
1) only boots to fastboot, and even does this when you leave it powered off, but charging.
2) select hboot, then to recovery, recovery doesn't run, just resets back to fastboot eventually, after screen goes white not black.
3) can partially speak to phone in fastbook and get versions ok (included below)
Getver all as below:
C:\Program Files (x86)\Minimal ADB and Fastboot>

finished. total time: 0.114s
4) never been able to boot to full o/s so not in developer mode, so cant get response in adb (and dont know how to use this anyway)
5) tried RUU.exe - fails with usb error after it tries to restart bootloader
6) tried ruu.zip from memory card - fails with partition update fail
7) tried fastboot recovery image 6.12.401.4 and it fails to write - error is 'remote:signature verify fail'
8) random google lead me to fastboot oem reboot RUU which does this:
E:\android tools>fastboot oem rebootRUU
...
(bootloader) Error: Command never completed
(bootloader) Error: Command timeout error
(bootloader) Error: Command completed with errors

9) htcdev unlock bootloader didnt work initially but has done now - is this a path i should try?
aim is to get a standard phone working again
Thanks
G

ok got my unlock token, seemed to flash it, but no status change/reaction on phone and rebooting still shows locked
E:\android tools>fastboot flash unlocktoken unlock_code.bin
sending 'unlocktoken' (0 KB)...
OKAY [ 0.125s]
writing 'unlocktoken'...
(bootloader) unlock token check successfully
OKAY [ -0.000s]

My responses to some of your points below, in red font:

4) never been able to boot to full o/s so not in developer mode, so cant get response in adb (and dont know how to use this anyway) That is correct, you will not be able to use adb unless you can boot to OS or alternately TWRP custom recovery. So you are basically limited to fastboot in the current condition.
5) tried RUU.exe - fails with usb error after it tries to restart bootloader There isn't a valid exe format RUU for your version number (6.12.401.4) so you are probably using the wrong RUU. What is the version number or file name for the RUU.exe?
6) tried ruu.zip from memory card - fails with partition update fail Exactly what partition(s) is it failing to update? What is the version RUU you are using? The only valid one for your version would be the RUU.zip from here: https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
7) tried fastboot recovery image 6.12.401.4 and it fails to write - error is 'remote:signature verify fail' You can't flash an unsigned recovery image, unless the bootloader is unlocked. It also seems you are trying to flash stock recovery, and I don't see how that is going to help your current condition.

I think your best bet right now, is to try the correct RUU.zip which I linked above.
