Can't escape from boot menu. Help with installing any rom. - One (M8) Q&A, Help & Troubleshooting

I tried to update my phone to 6.0 from 4.4.2 with ADB. Came with an error "System partition size error". It doesn't see the SD card when I tried to install from it.
My phone stuck at hboot screen. I can only access recovery and hboot menu. And when I tried to update to Lolipop with exe from a computer it says "Error 155: Unknown error". Xp 32 bit USB 2.0.
After I said reboot system through TWRP and it said No OS installed! .
But I have already installed ViperOne 3.2.1 Kitkat and Stock 4.4.4 before without any error still can't escape from boot menu. Any help would appreciate.

And I think the device was T-Mobile 13000 at first but I'm not sure about it.

Did you update the firmware? I ran into a similar issue because my device shipped out with 4.4.2.
To update the firmware, you have to do the following:
Set your OEM's CID. Do not use SUPERCID.
My device was GPE, so [fastboot oem writecid GOOGL001]
Re-lock your Bootloader using Fastboot.
[fastboot oem lock ] then [fastboot reboot ruu]
You'll see the device logo centered onscreen.
Flash a firmware update file (does NOT have to be a whole ROM) and you'll be able to update to the threshold of that firmware.
I have Marshmallow firmware. So I can use MM or LP as well as KK ROMs now without bootloop.
Be sure to hit thanks if I helped! Be even more sure to PM me if you need help (like firmware files if you have the same variant).

My current firmware is: 3.28.401.9. Which one do you suggest to install? And I would really appreciate if you send me firmware files. I'm not sure which variant's firmware I should use.
Edit: By the way I can install roms but ruu.exe gives me error.

wrong ...
your firmware is 1.12.401.17 as shown on your getvar details on post #1.
and your device is a sprint device (m8_whl) and you should not flash any GSM firmware.
Sprint & GSM has different System partition size (your error)
change your model-ID currently shown as 0P6B10000 back to to sprint 0P6B70000
and install Sprint RUU or firmware. You can find them on Sprint forum.

He is S-Off. No need to relock the bootloader ever.
And for S-On users, the only time you will need to relock the bootloader is for running an RUU
Also, superCID will work with any firmware. No need to set the CID to his carrier's (not OEM's) CID

I thought so too. I'm also s-off but my firmware update stalled code 20 until I relocked the bootloader. But when I was finished I reversed that course [fastboot OEM unlock] and then dismissed the warning.
That's exactly what I did. Note that I mention RUU in my Fastboot instructions. :\

Thank you I will try and tell the results. I though that my device was GSM didn't even know that it was Sprint. I was totally wrong at first then.

Something I got in the Fastboot.
You open a command window and reference the file.
You either get a OKAY (milliseconds taken) or FAILED (error##). Some errors are obvious, like the cable disconnected, your recovery is out of date, update your SDK.

Sometimes remembering this stuff makes my head hurt. I often went to webchat to diagnose issues or find similarities.
Sometimes it's how I word a problem, the other time its the problem itself that throws off a bit... ?

How did you do that ? You wrote the code on your own instead of copy paste the whole code ? I don't know whether can fix that ... let's try again.
1. You need to install the old version TWRP recovery as your current hboot is 3.16.0.0000
install TWRP 2.8.1.0 - https://dl.twrp.me/m8/
2. After TWRP 2.8.1.0 installed, boot to recovery
mount - system
3. connect to PC and open a command prompt from your fastboot/adb folder then run command
adb shell
then this code (copy and paste .. don't write them on command prompt on your own)
Code:
echo -ne '\x30\x00\x50\x00\x36\x00\x42\x00\x37\x00\x30\x00\x30\x00\x30\x00\x30' | dd of=/dev/block/mmcblk0p5 bs=1 seek=16384
exit
on recovery select reboot - bootloader
then run command fastboot getvar mid - you should have 0P6B70000 now (hopefully)

Firstly I want to thank you with your help I've changed model-id.
Then I installed this firmware: https://www.androidfilehost.com/?fid=24391638059059188
and the screen was like that: http://hizliresim.com/4lZjAL
I've succeeded to open boot menu. Then I tried to install this version: https://www.androidfilehost.com/?fid=24052804347796593
but sd card gave me "wrong zippe image!". When I tried to install with .exe it gave me "Error: 155 Unknown error". Couldn't install with command either. I think something is wrong with firmware or rom. By the way there's a text "OP6B100x" behind my phone. Are we sure about the variant of my phone? I'm not even sure which firmware and rom I should install. I appreciate all your help.

Text "OP6B100x" behind your phone most probably due to change of back cover.
Your getvar on post #1 clearly shown it is Sprint
meid: 99000499006617
product: m8_whl
where the "OP6B100x" should read
meid: 00000000000000
product: m8_ul
After you installed 6.20.651.3_full_firmware.zip, you should run the 6.20.651.3 RUU.exe (you should not get error 155)
but instead, you tried a lower version RUU.zip which require a htc_fastboot to flash it. I don't know what you meant by "sd card gave me "wrong zippe image!"". Was it you tried with external_sd method ?
about the screen that you get .. I don't know for sure .. maybe it's because your ROM version is wrong for the firmware that newly installed ... and maybe (the one that I'm always scare of) .. you previously installed GSM firmware 1.12.401.17 on a CDMA device which may altered some of your system partition tables.
That's why there's a big warning here : http://forum.xda-developers.com/showpost.php?p=51700638&postcount=2
warning! provided only for folks who have changed their mid and realized they shouldnt have,or achieved s off via a java card. DO NOT change a gsm or vzw device to this in attempts to use it on sprint and convert to a sprint device(or vice versa).​
Can you post current fastboot getvar all result after you made all these changes ? You may need to reflash the 6.20.651.3 and run 6.20.651.3 RUU.exe after the firmware installed.

Not Getting The OTA Update To 6.0

i just bought HTC M8 Days ago but it was pre rooted and on the 5.0.1 i cant update it to marshamllow
it S-Off and when i try to update it says you have the latest update
Software number
4.18.708.12
i tried to install OTA Flash via stock recovery but i got error
how i updaate manually or enable OTA's
dont wanna root now
please help me here
You can't install OTA on rooted ROM ... it needs pure non-rooted stock ROM.
You can try to restore only the system partition from non-rooted backup.
You can get the backup and stock recovery for 4.18.708.12 here : http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
i deleted root before doing any thing
can i do it without rooting or unlocking bootloader because i dont know how to do it on HTC Phone and those CID and stuff really bug me out
itried flashing ota with stock recovery got this error
http://prntscr.com/bivh4o
whats wrong here ?
Why on post #1 you said you have HKG 4.18.708.12
But in your screenshot you tried to install EU 6.12.401.4 OTA
and it failed because your stock recovery is TMOB US.
Post here fastboot getvar all result without serial & imei no.
We need to make sure the correct version that you have.

if the first cid and mid is the current now you can't flash Tmobile RUU
( there is a simple fix for this issue as you said your device is s-off but i'm afraid to say it,then you screw up )
so post the result of fastboot getvar all ( after removing serial and imei numbers ) to be certain what you need to do
and don't use an app to read cid and mid

Are you located in US and on T-Mobile network ?
If no, I suggest you to change the MID to EU MID 0P6B10000 then install EU Marshmallow RUU.
Some say once you have SuperCID, there is no need to change MID as SuperCID will override MID but in my experience that will never happen (flashing a modded firmware.zip is different as it has almost all MID in its android-info.txt). Unless you MID is SuperMID, you need to change MID to EU if you want to install EU RUU.
You can follow this guide to change MID - https://forum.xda-developers.com/showthread.php?t=2708581
then install RUU - https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
If yes, in US and on T-Mobile network, you need different approach.

Then go for the option that I mentioned earlier.
First - change MID
Second - install RUU
Change MID
What you need to do .. boot to bootloader and install TWRP - maybe version 2.8.7.0 will do
https://dl.twrp.me/m8/
after you install TWRP - boot to recovery
Mount - system
then open command prompt from your adb/fastboot folder
then type
adb shell
follow by
Code:
echo -ne '\x30\x00\x50\x00\x36\x00\x42\x00\x31\x00\x30\x00\x30\x00\x30\x00\x30' | dd of=/dev/block/mmcblk0p5 bs=1 seek=16384
don't write yourself the code, copy and paste
then type exit
select reboot menu, select bootloader
then install RUU
Edit : your bootloader is locked, relocked or unlocked ? If locked and relocked, you can't fastboot flash the TWRP in normal way.
Download this : https://forum.xda-developers.com/showpost.php?p=70439093&postcount=412
No worry about the OS no. that will be changed later once you install RUU
fastboot oem rebootRUU
fastboot flash zip 0P6BIMG.zip
fastboot reboot-bootloader
then follow with the above to change MID
Install RUU

Not enough info to say, for sure.
Which RUU number?
Exactly where does it get stuck? Any error messages?
After double clicking the ruu the installaion wizard pops up and after selecting the next option the installion bar goes to full and after that installion wizard vanishes and nothing happens.

RUU problems are usually on the PC end. Try a different USB port, or different cable. Try to re-install HTC Sync and HTC drivers.

I WAS TRYING TO INSTALL SPRINT FIRMWARE TOO BECAUSE I HAD ALREADY FLASHED THAT FIRMWARE ACCORDING TO EUROPE ROM. NOW THE PROBLEM IS THAT I AM UNABLE TO FLASH FIRMWARE DUE TO CHANGED MID (talked earlier) CANNOT UNDERSTAND WHAT TO DO.
Do you still have TWRP installed ?
If no, install one
If yes,
Boot to TWRP recovery, select mount - system
open command prompt from your adb/fastboot folder then run command
adb shell
then this code
Code:
echo -ne '\x30\x00\x50\x00\x36\x00\x42\x00\x37\x00\x30\x00\x30\x00\x30\x00\x30' | dd of=/dev/block/mmcblk0p5 bs=1 seek=16384
Make sure you copy the code, not write it yourself
then exit
then select reboot - bootloader
then run
fastboot getvar mid
you should see your mid now read 0P6B70000
(you don't need "su" command)
Now you can install Sprint RUU - http://www.htc.com/us/support/htc-one-m8-sprint/news/
or check those in Sprint section that I linked above
Note : You will get your device running again but you maybe lost the 3G/4G and only can get 2G. Reason is you flashed wrong radio meant for GSM on your CDMA, this usually brick the radio. If you're lucky enough, this is not happening.

this is what now comes up when i try to flash TWRP

i'm brain dead nothing works SUGGEST SOMETHING
EVEN UNABLE TO UNLOCK BOOTLOADER NOW
You can't fastboot flash recovery while the bootloader is locked/relocked.
You need a microSD.
Download the 0P6BIMG.zip that I posted here : http://forum.xda-developers.com/showpost.php?p=67526388&postcount=387
No need to worry what OS it is written for now, it will get fixed when you install RUU.
Place the 0P6BIMG.zip on root of microSD (means not in any folder)
Then put your phone on hboot, it will scan the file. Volume up to update (install). Once done, it will ask you to reboot but you know that your device is bootlooping, just put the device on bootloader (remove the microSD to delete the 0P6BIMG.zip)
Now you can boot to TWRP recovery and do the rest as described above.

Moreover, i made mistake that i also had flashed firmware file according to htc europe rom. Now which one should choose.
Doesn't matter about the firmware now .. just install RUU.
That was the guide written above.
1. Change MID
2. Install RUU exe that is linked above.
Make sure you have windows PC with usb2.0 and the latest htc usb drivers are installed.
HTC USB drivers - Install HTC Sync Manager - http://www.htc.com/us/support/software/htc-sync-manager.aspx
- it will install the needed drivers then uninstall the HTC Sync Manager but leave the drivers.
Or you can use RUU zip
0P6BIMG_Sprint_HTC_One_M8_6.20.651.3_RUU.zip that you can get in Sprint thread.
Rename it to 0P6BIMG.zip and install the same way as you installed TWRP above (microSD method)

It says that Device halted due large image update file
What do you suggest now.
Then install 6.20.651.3 Signed Full Firmware first, see whether it can be installed.
Rename it to 0P6BIMG.zip and install it microSD method. If successful then install RUU.
(This is the problem .. I don't have Sprint device, unable to test)

There is another problem occured i flashed signed firmware now phone only shows the HTC logo and unable to restart what should do now???
Was the firmware installation successful ? This is important.
When you reboot, there is no OS, you need to put back to bootloader then install RUU.
(Same way after you installed TWRP before)
I think this is easier.. instead of going to Marsmallow, install the lollipop first just to get your phone up & running.
Install this 0P6BIMG_Sprint_HTC_One_M8_4.25.651.18_RUU.zip, for this you don't need to install firmware.
Once successful, then you can try again to install Marshmallow 0P6BIMG_Sprint_HTC_One_M8_6.20.651.3_RUU.zip but
you need to install 6.20.651.3 Firmware first.

SO you have no cell data access?
What bands does your carrier uses for 3G and LTE (what band for each of those - they are 2 different things).
karamghumaan said:

Hotspot is locked out on most US carrier versions. If you don't see Hotspot as an available "tile" in the notification quick settings, and no Hotspot widget, than the feature has been disabled on your stock ROM.
Easiest way to enable Hotspot is with the proper custom ROM (supports Sprint version M8).

Trouble locating origin of One m8

Hello to you all,
I thought about asking in the help thread but my post will be somewhat long XD
I'm having trouble locating the origin of my HTC One M8 that I bought 2 days ago in bulk from a local shop. It's new, SIM Unlocked, but apparently rooted and S-OFF, figured it was needed in order to unlock it from it's former carrier, which brings me to my question : I want to know it's original carrier and region in order to safely select RUU and ROMs and preferably I would like to do OTAs too. I want to know whether I'll have problems updating to Marshmallow in the future.
Now, in the back of the phone is written : model OP6B700, that would make it a Sprint device right ? which from what I read is pretty delicate to work with, being CDMA and all.
CID Getter gave me : OPTUS_001
And here is my fastboot getvar all :
(bootloader) version: 0.5

(bootloader) hbootpreupdate: 11
(bootloader) gencheckpt: 0
I noticed I have superCID ... why doesn't CID Getter report it ? If I want to revert it back which one do I input ? I don't know the stock value.
I noticed my MID is OP6B65000 what model is this ?
Really confused right now should I go ahead and install OTA ? I have one notification version 4.16.401.13 that wants to be installed.
Also I have "unknown" under HTC SDK API level, don't know why.
It seems I have the 2.5Ghz version of S801, but some utilities report AC variant some others AB. I got 63k on AnTuTu 6.2.6
Other than that the phone seems to be running really good, snappy, no lag, gets a bit warm with light usage, I don't think I got a fake one but correct me if I'm wrong.
It's in airplane mode, haven't put a SIM card in yet.
So what do you guys think ? I surely appreciate any insight you might have

Based of the info above especially the MID 0P6B65000 & 2.5Ghz .. that's an Optus device ... originally from Australia. The original CID is OPTUS_001

You can't do OTA to 4.16.401.13, won't work .. you'll get system variant error with OTA.

You should put a SIM to test whether it's really SIM unlocked from Optus.
Also to check whether LTE is working fine.
Where are you located ? You have a S-Off device, you can install any region GSM RUU (if available) but not OTA to 4.16.401.13 when your OS on bootloader is shown as Hong Kong and MID is Optus Australia.

Thank you for replying
To answer your question, my location is north africa. Tomorrow I'll get a nano SIM to try.
The information you provided raised some more questions :
1- I can't do OTAs, so the only way to update for me is through RUU or custom ROMS ?
2- I have a Hong Kong OS, can I change it ? will I have to change the MID and CID accordingly ? I can choose whatever values I want it won't cause any problems ?
3- How come while in OS I have different build numbers than in Bootloader ? in OS I have build version : 4.16.401.10. That's europe version right ?
4- Let's say I want to revert everything back to stock international version with Sense etc, to be able to do OTAs, what do I have to do ?

You can do OTA only if you put the Optus ROM in your device. The problem is back to Optus and do OTA may break the SIM unlock.
But why do you want to OTA ? You can manually direct update it to Marshmallow if that is your intention.

You don't need to change the CID, let it be SuperCID but you may need to change MID (some people said no need to change MID when SuperCID but personally I don't experience a success firmware flashing without proper MID)
You can only choose any value meant for GSM but not CDMA. While on SuperCID, you need only change MID or change it to SuperMID.

Bootloader info is your firmware info.
OS no. in settings is Software info.
So this is like you're running a custom ROM, running a Europe ROM on Hong Kong firmware.

Hi, sorry for delayed answer.
Bought a new nanoSIM today, seems to be working fine, made a few calls etc... LTE isn't available in my municipality yet, it will be in the upcoming months but I have the option to select it. I did test HSPA though and it works fine. I guess it's fully sim unlocked then
Regarding OTA, I just saw it as an easier way to update than the commands I had to enter to flash via RUU and all... I guess now I have to learn them alright
So it's my firmware that's from Hong Kong, I didn't know that thanks for the clarification.
Sorry I have more questions
1-Now that I'm running HK firmware and corresponding MID but EU ROM, you suggested I change to EU MID, but won't that cause issues with firmware being HK ?
2- If I flash the EU RUU you sent me, I assume the firmware will no longer be HK, correct ? and after that I can just keep to install EU roms and be trouble free ?
3-I assume that my simUnlock is definitive now, correct ?
4-You seem to be certain I have superCID, so bootloader info trumps CIDgetter info, but I'm curious, why the value differs between the two ? does the app not report it correctly after changing the value ?
5-I will be downloading the files from the links you sent me, and doing my homework too but for information's sake, when I boot in bootloader, I have the "locked" banner, but you know that already I also have "software status : official" does it indicate that the Lollipop EU ROM I currently have is a stock signed one ?
6-My device came rooted but I don't see Superuser installed, I assume I'll have to root it again after the update, correct ?
A Big Thank you for the big help :good:
1-Now that I'm running HK firmware and corresponding MID but EU ROM, you suggested I change to EU MID, but won't that cause issues with firmware being HK ?​You have OS Hong Kong no. which I assume it's HKG firmware but your MID is not HKG but it can be Australia and it can be India. I assume it is Australia as it has 2.5 Ghz and CID OPTUS001 (as you mentioned it)
Change it to EU MID won't cause any issue but a better option as the current ROM on your device is EU 4.16.401.10 and that's why you get notification for OTA to 4.16.401.13
2- If I flash the EU RUU you sent me, I assume the firmware will no longer be HK, correct ? and after that I can just keep to install EU roms and be trouble free​You need to change MID first to EU then install EU RUU. The firmware will be EU, no more HKG. You can install any GSM ROM after that, trouble free.
3-I assume that my simUnlock is definitive now, correct ?​Yes it is SIM unlocked, the reason why I don't recommend Australia Optus firmware & ROM so it won't get SIM locked again. The best option is EU as you're in North Africa.
4-You seem to be certain I have superCID, so bootloader info trumps CIDgetter info, but I'm curious, why the value differs between the two ? does the app not report it correctly after changing the value ?​That's what shown on getvar result. No idea about the app. I tried, it can't read my CID as I'm running Nougat ROM. You can try Simple CID Getter to recheck.
But getvar is always correct and the best option.
5-I will be downloading the files from the links you sent me, and doing my homework too but for information's sake, when I boot in bootloader, I have the "locked" banner, but you know that already I also have "software status : official" does it indicate that the Lollipop EU ROM I currently have is a stock signed one ?​Most probably.
If you want to see whether it is stock non-rooted, you change MID to EU then you can accept the OTA and see whether it will be successful to install.
As you have a LOCKED bootloader, you need different method to change the MID .. you need to install a flashable TWRP and do the MID change while in recovery.
But why want to waste time checking, downloading and installing OTA when RUU is available and you can directly update to the latest.
6-My device came rooted but I don't see Superuser installed, I assume I'll have to root it again after the update, correct ?​How do you know that it is currently rooted ? OTA won't work on a rooted ROM.
Yes, you have to root again after each update (when you need a rooted stock ROM). If you want to install custom ROM, no need to root .. only install TWRP and install custom ROM. Custom ROM mostly come pre-rooted.

For the CID, with Simple CID Getter I get the same OPTUS_001... no idea why XD
Upon installing CPU-Z to have more information about the device I noticed "root access : yes" so I installed Root checker and indeed it told me I have root access, that's how I knew about it. Well then I don't plan to OTA anymore XD
The first method to change MID that you sent me doesn't work even if I'm S-off ? so I'll need to use this tool ? http://forum.xda-developers.com/showthread.php?t=2779524 if so then the sequence order should be : Unlock bootloader from htcdev, then flashing TWRP like you said here http://forum.xda-developers.com/htc-one-m8/help/unlock-bootloader-install-custom-t3371328 then using the MID changer tool ?
I don't need to revert to stock recovery and locked bootloader before flashiing with RUU ?

1. No idea why these app read differently. Just ignore it for now .. that can be fixed later
2. Don't follow those guide .. I'll give you the guide below
3. No need
First - you need to install TWRP.
a- Download the hboot flashable zip here : http://forum.xda-developers.com/showpost.php?p=70210155&postcount=19
b- put it on root of your microsd
c- boot to bootloader then select hboot - it will ask you to update, volume up to update .. let it finish, reboot once completed. Delete/remove the 0P6BIMG.zip from your microsd.
Second - you need to unlock bootloader as it is easier to thing with unlocked bootloader
a- boot to bootloader - select hboot then recovery
b- once in recovery, select mount and mount system
c- open a command prompt from your adb/fastboot folder then type (one after another - suggest you copy paste the code, don't manually type them
adb shell
Code:
[B]echo -ne "HTCU" | dd of=/dev/block/mmcblk0p2 bs=1 seek=33796[/B]
exit
reboot to bootloader .. you should see the bootloader is now unlocked.
Third - change MID to EU MID 0P6B10000
a- boot to bootloader - select hboot then recovery
b- once in recovery, select mount and mount system
c- open a command prompt from your adb/fastboot folder then type (one after another - suggest you copy paste the code, don't manually type them
adb shell
Code:
[B]echo -ne '\x30\x00\x50\x00\x36\x00\x42\x00\x31\x00\x30\x00\x30\x00\x30\x00\x30' | dd of=/dev/block/mmcblk0p5 bs=1 seek=16384[/B]
exit
reboot to bootloader
open a command prompt from your adb/fastboot folder then type
fastboot getvar mid
you should see the MID now read as 0P6B10000
Fourth - your device is ready, you can install RUU as per my earlier guide.
Note : if there is error related to CID ... we'll fix it after you tried the RUU. If the SuperCID is correct, the installation should be fine.

Doesn't matter what already ticked, the important part is mount system (tick) as it is not mounted at default. The rest let them be as what they are when you select mount menu.
I'll check tomorrow your progress .. time to sleep now as it's over 1.30 am here.
Good luck.

EDIT : I successfully unlocked and changed MID to 0P6B10000 there seems to be no problem at all and the phone is running fine I don't get the red developpement message on boot to OS, only when I boot to recovery, it doesn't really bother me for now. I don't plan to update to MM immediately though, this has been a lot of new manoeuvers to learn in one take plus I want to read more about eventual issues with apps after I update, so I'll be using the current ROM some time before using your guide again and updating. Thank you so much for taking me through this process, I learned a lot

htc one m8 tmobile software update problem

Guys, my htc one m8 tmobile op6b130 ( bootloader looked, s-off) current software 4.16.1540.8. ... It does not install the update and says that i must revert back to original system software because it is modified version.
so please guide me how to get it done.. how do i install the update. Thanks
What do you mean by software number (where are you reading the nubmer)? Best thing to go by, is the OS number listed on the bootloader screen.
Also, an OTA will fail if the phone is rooted, custom ROM, or even unrooted (needs to be a never rooted stock ROM).
If you know how, do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
Otherwise, did you change the CID or MID (and know what they currently are)?
Bootloader screen is like
Software status official
***locked*** S -off
cid -11111111
OS 4.16.1540.8
The model written at rear bottom of my htc is Op6b130 .
i get update with a number 4.17.1540.9 which does not install.
Thats the real confusion with me .. so please tell me the way how do i install the next updates.

The phone is heavily modified. It has some point been rooted, SuperCID (11111111) and had the US Developers Edition (4.16.1540.8) firmware and/or RUU applied.
Do you know the history of these mods; did you do them, or did someone else mod the phone?
Can't say for certain, unless I know more details. But the easiest way to update to the latest (MM) version may be to flash 6.12.1540.4 firmware, then flash the 6.12.1540.4 RUU.
I did not do anything like that. I got my htc in this form.
so if MM update is better. Can you please tell me the procedure of installing firmware and ruu file as you said. I would be very grateful to you for this.
Would this procedure be right for me?

Yes, that would actually work, and describes what I was talking about. Nice work finding it yourself!
I'm not sure whether you need to change the MID or not. CID is fine to run the 6.12.1540.4 firmware and RUU. And SuperCID will actually bypass the MID in some situations (but not all). Plus, with the info given so far, I can't tell what the current MID is (it may already have been changed).
If you do need to change the MID, you will also need root. So that would be more steps.
So my advice is to first skip the steps of changing CID and MID. Just go to the steps of flashing the 6.12.1540.4 firmware and RUU. If the firmware fails due to wrong MID, it will tell you that via an error message; and we can tackle that issue if it comes up. But if it works on the current MID, then we've saved some steps.
Best (most accurate) way to determine the current MID, is to do command: fastboot getvar all
Then post the output (delete IMEI and serial number before posting).
This will also give us a lot more useful info on the device.
You'll need to use fastboot anyway (for the guide you linked), if you don't already know how. So you may as well figure it out now. The command should also work with the htc fastboot given in the thread you linked, but would be: htc_fastboot getvar all

Good to go with 6.12.1540.4 flashing from the guide you linked
Flash the firmware.zip in RUU mode then reboot to bootloader make sure the new os number is 6.12.1540.4 then proceed to flash the RUU.exe

do I need to change Cid & Mid?
when i typed adb.exe shell .. it gave me error that no device is there .
although it showed me my serial number when typed adb devices. it ran fine.
but what's the problem with adb.exe shell?
secondly, is it ok to jump from 4.16.1540.8 to directly 6.12.1540.4?

You need to use the htc_fastboot to flash the RUU, as indicated in the guide you linked (and required files downloaded from there as well). The "generic" Android fastboot can't handle files that big.
Although, you should drop the ".exe" (indicated in the guide) from all the fastboot commands. I've never seen ".exe" included on fastboot and adb commands, and it will probably cause you an error like it did when flashing firmware. So the command should be:
htc_fastboot oem rebootRUU
htc_fastboot flash zip rom.zip

Yes, that is fine. Which is why I told you to do it. If anything else needed to be done, I would have indicated that.
RUU doesn't need to be installed in sequence, meaning you can skip a version(s). RUU is different from OTA, as OTA typically does need to be installed in sequence.
With s-off, you can even go backwards with RUU. Which is also something you can't do with OTA.
while flashing firmware , it first said 'failed' and then automatically came with 'finished and time' .
When i went to ruu .. i first used htc_command .. but it said that ' this command is not in internal and external blaa blaa'. So i went without htc_ and got stuck and waited about half hour for that. Then , knowing nothing i did factory reset with wipe cache to restore my phone back to 4.16.1540.8.
Are there any pre-requisites that phone shold be unlocked and rooted (as i saw some videos on youtube)?
My phone is s-off, bootloader locked and no root access.

If it gave a message about "flush image immediately" this just means you need to flash the firmware again (needing to flash 2 times is normal and expected).
If the firmware installed correctly, you will see OS 6.12.1540.4 on the bootloader screen, and also see 6.12.1540.4 for "version-main" if you do fastboot getvar all.
You must have 6.12.1540.4 firmware properly installed, in order to flash the RUU.

You are getting that message, since you are not executing the command from the folder where htc_fastboot.exe is located. After you download htc_fastboot from the thread you linked, open Command Prompt in the folder (Left Shift + Right Mouse Click) and run the commands.
Leaving off the "htc" means you are trying to use the "generic" fastboot tool (fastboot.exe). Which would also confirm the fact you are probably running the command from the wrong folder. Again, using the regular fastboot will never work, since it can't handle the file size of the RUU.

You mean prerequisites for the RUU? If so, saying bootloader unlocked and rooted are prerequisites is false and incorrect. If you saw it on a YouTube, you are confusing RUU with something else.
Bootloader locked is normally (s-on) a requirement for RUU. But since you are s-off, it will run with the bootloader unlocked, locked or relocked.
Root has no effect on RUU. RUU will run, whether the phone is rooted or not.

What exactly are you trying to "restore" or accomplish with this? It's not clear you have even installed anything past 4.16.1540.8, to begin with.
Finally did it successfully!

Basically, Sprint (and most US carrier versions of the M8) won't update if not connected to that actual US carrier (Sprint, in your case). Also, you can NOT "modify" the Sprint version to make it another version (such as Euro), and the reason for that is that the Sprint version you will radio brick the device doing this! So don't try it!
You can update using the RUU meant for the Sprint M8 (and only the RUU meant for the Sprint M8, for the reason mentioned above). Whether you need to update or not (by RUU) depends on what it says in the getvar info I asked for above.

Can't revert HTC One M8 to stock

I received an unlocked HTC One M8 (US, works on AT&T, not Harmon Kardon), factory reset, never been modded. Because it ran Android 6.x, I was concerned that it wasn't as secure as it could be, so I researched how to install the newest Android possible. I found many articles on these forums, guides from 2014 all the way to 2016. I didn't (and still don't) know enough to tell the difference between a good tutorial and a bad/outdated one. I saw that some tutorials were edited to reflect new mods, but now that I have read even more, I suspect that even those updated ones are now obsolete.
My problem is that I installed Resurrection Remix with v7.1.2, along with pico Open Gapps, and it won't let me install several apps like Chrome or even YouTube. I have decided that I don't want a newer ROM and I would rather just revert to stock. I have been attempting to revert to stock for the last three or four days, and I have spent many hours researching and reading (mostly this site...go figure), but so far I have not accomplished anything.
Current information about the phone: I did not make a backup (I've had little success doing this over the years on Android phones), I unlocked the bootloader with the HTC unlock code.bin file, the phone has S-ON and has not been rooted. In fact, I've tried SuperSU and Sunshine and neither worked. I have TWRP 2.7.1.0 installed. I have drivers from HTC Sync, but I also installed the Android Studio, along with some utilities that come with it. I have attempted the RUU from HTC (RUU_M8_UL_M60_SENSE70_MR_BrightstarUS_WWE_6.12.1540.4) and it always says that there was an error.
I have attempted several times to change the CID, but only because a tutorial told me to. I assume that it was changed when I installed the Remix mod. I have no idea what it should be. I have attempted to install firmware as well, both with the adb method and by copying it to the SD card and renaming it for bootloader, but both options fail. The adb method fails with...
(bootloader) zip info parsing...
FAILED (remote: 99 unknown fail)
...and the SD card method thinks for a bit, then says "press power to reboot" in the same type of text as the bootloader text.
I am only a little familiar with adb and fastboot, so please, be gentle. If you list commands, I will use them without even thinking, like how Ron Burgandy reads everything on the teleprompter.
Please help.

Hi,
no you did not post in the wrong forum. This section is not that active but there are still a handful of people visiting and trying to help.
You've posted plenty of info - which is good. First of all, you can't change the cid if you're s-on. You need to be s-off. Changing the cid is not really necessary unless you want to convert your carrier device into the dev edition or the Google Play edition M8. What cid were you trying? Was changing the cid successful? In that current state it shouldn't.
Speaking of the Google Play edition. You tried to revert to sense stock, according to the ruu you mentioned. The thing is your getvar result shows that your mid and cid directs towards a Google Play edition device. If you want to go on sense there are a few steps you have to do before you can (repartitioning system for example as the storage size is bigger on sense than on GPe).
Another thing is, the TWRP recovery you used is way too old for the firmware. The latest one can be found on twrp.me
Can you tell us how big your system partition is? If it's only over 1GB you certainly have a GPe device - in fact getvar says that as well.

The guide I found for reverting to stock said to change to the super CID (fastboot oem writecid 11111111). I only did that because I thought that it was the "right way" to do this. But if the CID can't be changed unless the phone is s-off, then it must still be stock, because I doubt that I've ever achieved s-off while flashing a different ROM.

Yes, I attempted the Sense stock because the tutorial told me to and also because that's what is listed on HTC's website. I don't want to go to Sense, just thought that I was supposed to. So you're saying that the phone is a Google Play Edition? I'll need to look that up.

Thank you for that, I didn't know. I'll get it. One question that I've never found the answer to is, if I installed TWRP to change the ROM, what is the stock recovery image? Or, is it bad to simply leave TWRP installed? I have no plans to sell the phone.

I think I did this correctly. Here's what I found through the shell:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/block/mmcblk0p45 1032088 853196 178892 83% /system
Once I started looking this up, I found a post on XDA about GPe and different partition sizes. I'll check for GPe ROMs now. Do I need any other files besides that and the updated TWRP? Is the order to install a newer TWRP, then flash the GPe ROM, and then relock the bootloader?
I noticed that the bootloader has a persistent message about it being relocked and **WARNING**. Is there a way to clear the warning flag? One of the tutorials that I was following listed several shell commands to do this. I'm going to list them, so let me know if that is the way to clear the flag.

Thanks for your help.
You indeed have a GPe device. If you want to go back to GPe this thread has all your answers, links and ruu's

Since your device is a GPe device there is no need to change cid, mid etc. - with s-on you can't change them anyways. Just grab the latest GPe ruu and follow flashing instructions.
Stock recovery is only needed for ota-updates. On sense the updates would fail as this particular recovery is missing. I assume on GPe that would happen as well. It's up to you if you use twrp or stock recovery. GPe won't get updates anymore, same as sense.
I recommend not to mess with this stuff in bootloader. Once you go back to stock (ruu etc), it should fix itself. Besides that to temper with it you need to be s-off anyway.

Yes, I had found that exact thread earlier today, thanks to you, and I was just replying to tell you that I have successfully reverted my phone back to stock.
In the spirit of contribution to the site that has helped a novice such as me, I want to share the steps I took so that others might be helped.
The phone, as mentioned earlier, is an HTC One M8 Google Play Edition (Gpe), was s-on, not rooted, bootloader unlocked. I had an old version of TWRP and Resurrection Remix ROM using Android 7.1.2.
Prerequisites
1. Stock GPe ROM: https://androidfilehost.com/?fid=817550096634750828
2. TWRP 3.1.1-0-m8: https://dl.twrp.me/m8/twrp-3.1.1-0-m8.img.html
3. Backup account fix (linked in aforementioned thread): https://www.androidfilehost.com/?fid=24686680535467942
4. ADB and fastboot
5. Unlocked bootloader
**This assumes that you have a Windows computer. I used Windows 10 v1709**
Steps
1. Copy the ROM and TWRP files to the same folder in which fastboot and ADB are located. This makes it easier to run commands.
2. (There might be another way to do this one, but I don't know it) Copy the backup account fix file "MRA58K.H15_backup-account-fix.zip" to a micro SD card and put it in the phone.
3. Open a command prompt or PowerShell window in the folder that contains ADB and fastboot by right-clicking + Shift in an open area and selecting "Open PowerShell/Command Prompt window here."
4. In the PowerShell/Command Prompt window, type "fastboot flash recovery twrp-3.1.1-0-m8.img" and press Enter to install TWRP
5. Reboot into the bootloader and choose "fastboot," then choose "recovery"
6. In TWRP, browse to ADB sideload and then "swipe to start sideload."
7. In your PowerShell/Command Prompt window, type "adb sideload HTC_One_M8_GPe_Marshmallow-6.0_MRA58K.H15_AROMA-Installer-v6-020817.zip" and press Enter to start the installation
8. On the phone's screen, choose the top option, which should be the unrooted, completely stock installation.
9. On my machine, the PowerShell/Command Prompt window showed progress up to 41% and then it finished successfully.
10. After that, do not reboot, but go back into the main TWRP menu and go to Install. Browse to the MRA58K.H15_backup-account-fix.zip file that you previously saved on your SD card and install it.
11. Once that is installed, reboot the phone. My phone took between 5 and 10 minutes to boot the first time.
12. (Optional) I wanted to have a completely reverted phone, so I locked the bootloader again by rebooting the phone into the bootlader and typing "fastboot oem lock" in the PowerShell/Command Prompt window. It then said "relocked" but no warnings or errors.
I hope this helps somebody. All credit goes to maultasche for pointing me in the right direction and to graffixnyc for the other thread.
