Confirm this?? If S-off, I can flash recovery with bootloader locked?

It is so hard to re-locate threads between this general HTC One M8 and the variant for the carriers....so I hate adding to repetitive questions in threads....
BUT... I was certain that I read countless times that you could flash recoveries from ADB with bootloader locked provided you had S-off.
And now I am getting this error:
FAILED (remote: not allowed)
I had two updates and wanted to flash stock recovery then reflash TWRP.... I thought it would take 20 minutes tops....

SO I said f*ck it... no big deal, and I unlocked the bootloader and flashed the stock recovery (btw, I flashed a stock recovery I found in the TMO forums that had a version number identical to the software version I had installed, this is correct right????). I had no problems flashing the stock recovery....so apparently, you need to unlock the bootloader whenever you are flashing recoveries irrespective of whether you have S-off.
But then, I tried to run the OTA, and got the red triangle error.... — Is this because my bootloader is now unlocked?
This seems to be going against everything I have read numerous times (namely that if you are S-off, the bootloader is not that big of an issue). I am assuming this is because my bootloader is now unlocked... so I will unlock it.

IGNORE

Just adding my experiences as I don't want to start another thread with new information...
I have unlocked bootloader
flashed stock recovery
relocked bootloader
went into setting==>apps and enabled the 10 or so apps that I had previously disabled...
I even deleted all downloaded OTA updates and had the phone re-download them again.
However, I still cannot install OTA updates. I know that the standard instructions are to flash a stock rom or restore a nandroid that is stock, but my phone is stock!!! Nothing has touched any of the original software on it other than the stock recovery, which I flashed back on it...
I think my phone is techincally still rooted because it has the SuperSu binary installed... But (again) from everything I read, the way I understood it was that in order to get OTA updates you needed to have stock (or pretty close with no uninstalled/frozen/disabled system apps), and the stock recovery.... AND that is it....

I removed it just before I saw your post... but thanks! And thanks for replying.
I am trying to install the 2.22.531.6 OTA software.
I don't know if the bootloader/hboot version has any correlation to the software, but I have not touched anything... I did two updates, then a three days later did HTCDev unlock of bootloader, I flashed TWRP, flashed SuperSU, got Sunshine S-Off, then relocked bootloader. As mentioned I also disabled a bunch of apps. But as of now, I have re-enabled them.
The only variable that wasn't precisely in my control was the stock recovery. I didn't know which one to flash, but made the common sense decision to flash the 2.22.531.5-TMO-Recovery.img since the version number of the recovery matched exactly the version number of the software that is showing on my hboot screen. I thought that was a educated guess that wouldn't be too risky.
I haven't flashed or changed the hboot, or flashed any RUUs....nothing else.
really confused....because aside from the recovery, I didn't touch any of the firmware.
NB: I do have a nandroid that I made that is entitled: 2014-09-24-14-06{whatever) release keys I don't know what release keys means.... I have made a lot of nandroids in my time... 95% of them on HTC devices using TWRP (at least since its inception), and I have never seen a "release keys" appended to the name of an nandroid like that.
I could restore this nandroid... but then I would have to unlock the BL, fastboot flash TWRP, flash SuperSU (although I know TWRP now prompts you which is very cool), then restore the nandroid, fastboot flash the stock recovery, then (apparently) re-lock the bootloader, and get the OTAs.... if the OTAs even work...

Ok stock recovery flashed back is good then, you need to be completely stock to do OTA's i.e If you made changes to the system even removed pre-installed apps like Facebook, Twitter etc you need to restore those back as well. As the OTA will do a verification check to see that all those things are intact before it continues the update. If it's not stock then you're not getting OTA. Bootloader status won't make a difference, you can keep it unlocked.
When you do the OTA and it fails what error does it give? When an OTA gets applied it reboots the system to the stock recovery and proceeds to apply the update, if it fails you can view the error. You can press Volume Up and then TAP the power button and it'll show you the recovery log details at the bottom, there it should tell you what errors you have during the OTA installation.
/system/app/blahblahblah has unexpected contents, or cannot find /system/app/blahblah etc
If it requires missing files etc just get them and add them back on the device. Like I said above, you need to be stock.

Cool... NEAT trick I didn't know about that...!!! thank you for the tip. They should put that in the documentation with the f*ckin phone.
The recovery/installation log says (in relevant part):
Verifying current sytem. . .
"/system/build.prop" has unexpected contents
Installation aborted.
I thought about why the build.prop would have changes, and remembered that I have an app called Android Tweaker Pro (but it is being renamed since Google now prohibits apks with 'Android' in the name). It requires root to make its tweaks. Its a good app, but it does make a lot of changes to build.prop. But... am pretty sure it has a reset/restore to default option on it... I am going to check and try that.
Will let you know...
Sh*t.... still can't believe I didn't know about the installation log screen... very impressed.

And so we all learn new things everyday It's great!
[Recovery] [RUU 2.22.531.6] [TWRP Nandroid Backups] [Radio IMGs][ OTA 2.22.531.6]
There's a stock backup for 2.22.531.5 in there that you can restore to go back to stock for the OTA. Changes to build.prop usually is changes to system. Perhaps you could also try and pull the build.prop from there and restore that and see if it works

They also have the 2.22.531.6 stuff there so just make sure you select the correct versions, it's under the "clickable" buttons so...

OK.... I used a app called Nandroid Manager (very helpful app) which extracts anything you want from a nandroid. Since I had already disabled the Android Tweaker 2 App, and realized I had an original build.prop in that nandroid, I just extracted that and renamed the old one, and used the extracted one. I did a chmod 644, and then attempted OTA install.. And it went fine! Very nice... A bigger headache then I had anticipated... but it serves me right for forgetting that I had root apps modifying sh*t that I had not considered.
Very big thanks for the tips.
Also...lastly, since I stupidly relocked the bootloader, I am now no longer root but cannot flash TWRP because the BL is locked. I cannot use Scotty1223's method (I don't think) because it requires su permissions in adb shell.
I could probably just use the htc .bin file.... but out of curiousity, is there any easy way to get temp root in this case?
EDIT: Actually.... I would really like to avoid the htc unlock token as that erases the data partition as some kind of existential pennace ordained by HTC for unlocking your bootloader.

Yeah you can use the unlock binary you had if you went through htc unlock method, or you can just do it again if you want(another headache).
You'll have to read up on temp root methods, I haven't used any at all, so I'm not entirely sure, sorry.

Just saw your edit...you're right it'll probably wipe everything again.
Did you get S-OFF with Sunshine? I don't know if maybe there's a way to unlock the bootloader again even if you're already S-OFF If you didn't then it probably won't be feasible to pAy $25 just to unlock the bootloader, I'd rather then just back up everything and let the data get wiped doing it the HTC way.
Check the Sunshine Thread maybe, they had some discussions in there about temp roots if I recall correctly.

I have been spending the past 2+ hours researching this. Even worse, the HTC token no longer unlocks the bootloader.... So I have this great phone with S-Off, but no way to get root. In my first attempt with chatting with HTC, they said that they "were very sorry but [they] do not support 'unlocking the bootloader' as it is against the warranty". WTF????? I am trying to get though to HTCDev... luckily I didn't change my CID. But I hate waiting for this.... I do a lot of stuff on that phone with root privileges..
I tried adb root, adb root shell, adb shell su, and a whole bunch of combination.... no dice...
There is just no way to hack a way to get temporary root at this point. I have looked... Weaksauce has long been deprecated/useless once you are past 4.4.2.
My planned 20+ minute task today is now going into its sixth hour....!!

OP - try towelroot to gain root then use scotty's guide to unlock bootloader

If you are still S-off, just use adb to unlock the bootloader again.

However, there is still a solution. Use Sunshine to temp-root, then use a local terminal instead of adb.

When ckpv5 referred to Scotty's method in the post above yours, he is talking about the thread you linked. I am aware of that method and think it is great, but you need to get a shell... and you need root privileges in that shell in order to run the dd= command. That is just the way it works. It doesn't matter if you are S-off (this is why I have been frustrated). Until HTC replies to me, I am stuck with an unrooted phone with S-off.
I am going to try the towelroot method though... I forgot about that (thank you ckpv5).
If I can get temporary root long enough to unlock the bootloader.... then I can flash TWRP and I am good to go. We'll see.

Yeah, I had a bit of a brain fart on that one. I forgot you have to be able to su to execute that dd command, even s-off. However, I do know for a fact that you don't actually have to flash TWRP to re-root. When I did the same thing you are doing, I simply booted TWRP instead of installing it to preserve the stock recovery.
TWRP did have an issue booting for a while when using the firmware that came along with 4.4.3, but they appear to have fixed it in the last two versions. I ended up using CWM instead, but the effect is the same.

[Solved] Cannot install CM12 due to outdated bootloader

Hello.
I am currently running ParanoidAndroid 4.6Beta5. Since PA's developement for M8 seems to be dead, I wanted to try CM12.
When I tried to install latest nightly build of CM12 I got a message that my bootloader (3.16) is not supported, and that I need to update it to 3.18 or 3.19.
I googled a bit and found out that in order to update it, I need to restore latest official ROM.
I managed to restore official ROM (3.28.401.6, based on android 4.4.4) but the WiFi wasn't working, so I couldn't do much there. I relocked bootloader and flashed official recovery, and then tried to run RUU.
RUU failed with code [315]. I ran out of ideas and google results to browse.
I unlocked my bootloader again, flashed clockworkmod recovery back, and restored my backup of ParanoidAndroid.
Right now the phone is in the same state as when I was starting.
Here is some basic info about my phone:
Model: HTC ONE M8 16GB Unlocked (purchased on amazon; network free)
CID: HTC_001
Bootloader: Unlocked
Recovery: Clockworkmod Touch v6.0.4.8
S status: S-ON
Click to expand...
Click to collapse
So the basic question is: how to flash CM12 on HTC One M8? I spent so many hours on it without any result, so this thread is my last chance.
Edit: SOLVED!
See http://forum.xda-developers.com/showpost.php?p=58859881&postcount=13 for solution.

Since you are S-On, you can't just flash the firmware, which is the easiest way. But you can use this method.
I'll give you an RUU to flash. But before you flash it, backup everything that is important to you, because this will wipe your phone.
Download this.
Rename it to 0P6BIMG.zip (that's a zero not the letter)
Put it onto the root of your extSD (By root of I mean just on the card and not a folder)
Boot into bootloader and choose hboot.
Follow the prompts (vol up to flash, power button to reboot when done)
Congratulations! You now have the latest lollipop firmware.
Make sure you delete the renamed zip from your extSD when you are done. If you don't delete it, it will try to update again every time you go back to hboot.

Since you are S-On, you can't just flash the firmware

What do you mean by firmware. Bootloader or ROM? I did 'just' flash PA without a problem.
I guess the ROM you liked is the latest official one. By installing it I will get my bootloader updated and then I will be able to flash CM12. Do I get this right? or will I get stuck on stock forever?
Edit: I just tried to flash your image using hboot but it didn't work. Check file attached.
I checked MD5 checksum just to make sure that it did download correctly and it does match with the one on the download page. However, I did notice that when I'm trying to open that zip file on my PC I'm getting an error saying that the archive is corrupted.

It probably didn't work because you are S-On. The method I gave you is generally used by S-Off users to flash firmware, but since it was a signed zip, I thought it might work.
Rename the download I gave you to ROM.zip at put it into your fastboot/platform-tools folder on your PC. Then hook your phone up to your PC and fastbooot.

It's pretty much the same one. Maybe the other one is screwed somehow? Try with this one instead and hopefully you can get updated.

Is it not possible to just restore whatever ROM my phone came with and then just do the OTA update?

Yes. I got caught up in this method. You will also need the stock recovery (more important than the ROM) to use the OTAs. Plus your system partition has to be unmodified. That means no Xposed modules. If you have them, delete them using Xposed framework, then uninstall that as well.

So if I get this right, I just need to restore my factory ROM and Recovery image, then update it through OTA to lollipop. After that I will be able to flash my custom recovery and ROMs once again, right?
Do you have any links to the ROM and Recovery to my phone?

Success. For future generations, here is what I did:
Using fastboot getvar all command I found out that my phone was still mentally stuck on stock rom 1.54.401.5. Using this info, I downloaded matching nandroid backup of that ROM from here and restored it using my custom recovery.
Then, downloading from the same thread, I flashed back stock recovery image using HTC One 2014 (M8) All-In-One Toolkit V2.0.
I was back on my original ROM with original recovery, so I started doing OTA updates until I got to the official android 5.0.1. These updates updated my bootloader to version 3.19.
Having the bootloader that I needed, I flashed custom recovery and installed CM12 without any problem.
Thanks for help!

Hey, I just found this as I am having the same problem. I am trying to follow your solution, but hit a road block and was wondering if you could help. I ran the command "fastboot getvar all" in fastboot and got output similar to yours. Following your advice I looked at the line (bootloader) version-main: 1.55.605.2 which is different than yours, but okay I just need to find a matching one. But when I go to the link that you had provided I can't find a backup that matches mine (or at least I think I can't). What does it mean for it to match anyway? I'm getting so close! I want cm12!!

I did it over like 6 months ago. I can't remember any more. Sorry.
Anyway, CM12 has way too many problem on HTC ONE M8 to be used as a daily driver. I am using GPE Rom now, which I can recommend.

I just need to find some way to update my bootloader so I can get lollipop up and running. Thanks tho

The number needs to match exactly to restore to stock and OTA update the software/firmware (and therefore update hboot).
You can try to post on the following thread, and ask if someone can post the stock nandroid for 1.55.605.2 :http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Otherwise (if you can't get a stock nandroid) you may need to resort to getting s-off in order to update hboot (actually I recommend updating all firmware, not just hboot).

Hi there! I have a problem with my One M8 (S-OFF) - I cant flash any ROM on it. I can restore backups from a CM11 4.4.4 and an ARHD 41.0 but can't upgrade from either. I was looking at your solution and noticed that my ROM number is blank when I run fastboot getvar all. Is this a matter of concern? How can I flash a ROM again?

Your version-main is blank because of a bug in some older TWRPs. Update to 2.8.7.0. Flashing the new recovery won't fix version-main being blank until you flash new firmware though.
Also, you probably do have to update your firmware. You say you can't flash any ROMs, but you give no details.

Apologies, newbie here. I was looking for the correct place to place my request for help, when I found this thread and asked. I will put it up in the Q&A section.

M8 won't boot

Sorry about any terminology...
Recently my htc one m8 stopped booting. I had rooted it a long time ago and had a ROM that was working fine for a long time. No recent changes.
On normal boot it sits on the white and green text 'htc' forever.
If I boot with power+down buttons I get to a hboot screen, but choosing 'recovery' takes me to a white screen small pink 'Entering Recovery' text. Nothing happens. To even get power+down screen to be available I had to move two zip files from root of sdcard which I guess were related to the custom rom, being 0P6BIMG.zip and M8-GPE-03-16-2015.zip
I tried reinstalling twrp after downloading the latest .img file
fastboot command
c:\twrp>fastboot flash recovery twrp-3.0.2-0-m8.img
just says <waiting for device> whether on pink text screen or white 'htc'
I can see the sdcard through a pc card reader and manipulate files. Is there any way to copy files manually so it will boot?
This is on Win 10, UK unlocked version of phone.

When you have a file named 0P6BIMG.zip, it will automatically try to install it every time you enter bootloader. Its an update or RUU of some sort, placed there by you, but exactly what is impossible to tell.
The other file is a ROM zip for a GPE ROM, which I would guess is the custom ROM you installed. It doesn't make a difference for this file not be on the SD card or not (bootloader will not try to install it automatically, and bootloader will function normally).

Are you in bootloader-fastboot mode when you run the command (which is required)? Meaning, FASTBOOT should be highlighted in red just under the green text on the bootloader screen. If not, just select using the vol buttons, and confirm using power button.

Thanks for your reply.
I guess the 0P6BIMG.zip file would explain why it was always slow to boot when things were working ok, if it was being reinstalled each time. I don't recall its purpose.
I wasn't in bootloader-fastboot mode when trying the fastboot command, but have tried it again.
When connected to an Ubuntu 16.04 machine the white on red text says 'fastboot usb', but ubuntu commandline fastboot flash ... gives same 'waiting for device'. When connected to Win 10 white/red text just says 'fastboot', if that is relevant. When I installed fastboot on Win 10 from instructions at http://forum.xda-developers.com/showthread.php?p=48915118#post48915118 there is a note to remove Google drivers before installing new ones - I did not do this, not sure if relevant, but new driver install gave no errors.
Is there a way to copy a new ROM image to the sdcard so that on 'normal' booting it gets detected and applied? Or to copy twrp somewhere manually?
Is there a log file that would show how far through the normal boot things get? I guess it is inaccessible until things work better.

Try going into Windows Device Manager, finding the device, and picking the option to manually select drivers, and select the generic Android MTP drivers. See if that helps fastboot connect.
Make sure you have HTC drivers (HTC Sync) installed as well. Try to re-install HTC Sync.

You can't flash a ROM, if TWRP isn't working properly. And there isn't a way to make one automatically flash upon normal boot, that I am aware.
I've seen some folks make 0P6BIMG.zip files for TWRP, which will install automatically when you boot to bootloader. But honestly, USB fastboot connectivity is a pretty vital thing to have working, and usually just a matter of right drivers and a good cable (and being in fastboot mode is a must), so shouldn't be that hard to troubleshoot.

The oldest ones don't run the newer ones work but I still get an error on attempting to install the custom ROM. I think I may be misinterpreting the error message. I now think it is telling me the custom ROM needs bootloader 3.19, rather than twrp not being able to run, i.e. twrp knows not to install the rom.

Shouldn't HTC be distributing these files? Or my carrier?

You need to relock bootloader if not yet done.
Command :
fasboot oem lock
fastboot reboot-bootloader
Then follow this : http://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
Put both files in your adb/fastboot folder.
(The guide was written for system-wide adb/fastboot)
Once completed, you can re unlock boorloader and install latest TWRP and install any ROM that you like, if you want to.

I have a working phone now, htc setup screens ended up with no google account prompts or apps, so I installed cwm nightlies and open-gapps hoping I would have full functionality, however gapps was rejected for not having enough internal storage.
I don't care whether htc or cwm but need gapps/play store. Is there anything you can suggest?

/Last reply lost..]I now have a working phone with cwm nightlies. Unfortunately open-gapps wont install saying not enough space on internal drive.
Any suggestions on how to clear space or to make HTC install Google accounts/store (it did not ask)?

I have a working phone now.
RUU didn't install google app store, so I installed cwm nightlies. I got an error that there was not enough space on internal for open-gappps.
Is there a way to free up space?

I have no idea what cwm nightlies is ... but if you have this kind of error not enough internal space ... you need to format data (not wipe) in TWRP.
Install latest TWRP, select wipe - format data - yes ... reboot to recovery again, now you can install ROM.

I installed a mini gapps that had just Play Store then installed other apps manually through that.
Thank you all for your help, this is a well-informed forum.
For anyone reading one thing I learned was to run fastboot from Ubuntu/Linux with 'sudo' or else it will not connect, just says 'waiting for device'

He means CM, not CWM. Easy mistake to make (adding one letter) but the two are completely different things (Cyanogen Mod custom ROM versus Clockwork Mod custom recovery).

I did make a mistake, I loaded both the below images in the given order.
openrecovery-twrp-2.7.0.2-m8.img
philz_touch_6.26.6-m8.img
When I went into recovery I got philz touch and loaded the UPDATE-SuperSU-v2.37.zip that was instructed. However I am got stuck in permanent reboot.
I followed the instructions in this thread up until post #6, but I don't understand how to "reflash my custom recovery". I am currently on the fasboot screen after having successfully run "fastboot flash zip firmware-2.22.531.5.zip".
Is this removing the philz touch image? How is this done?
Or more what I'm after, how do I get to a rooted phone from here which is usable?
Thank you in advance for any help given!

The chosen SuperSu is way too old. I never used Philz Touch but even TWRP you loaded is way too old as well.
Flash the latest TWRP and the latest SuperSu or magisk and you're good to go.
And please remove your imei and serial no.

Hold on, I missed this part. Why would you even flash this zip? I don't even know what that is. I'm not even sure this zip was intended for your phone. Flashing zips which are not for your device model could brick the phone.

The site only posts RUU for US phones.
Is the phone really in a bootloop or just stuck at the boot screen?
There is hope for you. Since you want to root as well we'll go this way:
https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Download the TWRP backup from post #3. It's the first one there for your device. After you downloaded the backup, flash the latest TWRP which I linked earlier. Boot into TWRP and restore the backup. If the phone is not booting then follow instructions in post #5 to flash firmware.
But before you go and restore a backup try to flash firmware as mentioned in post #5. You need to relock bootloader though.

It was originally just on the White with green "HTC" text boot screen. I'm now in fastboot.
So I have downloaded the following.
SuperSU-v2.82-201705271822.zip
twrp-3.1.1-0-m8.img
I also downloaded the below (on the mega-nz.com link).
hboot 3.19.0000 - 6.xx.xxx.x (Marshmallow)
CID ORANG001
MID 0P6B10000
6.12.61.4​
as well as the below from post #5
CID ORANG001
MID 0P6B10000
fw_6.12.61.4​
I attempted to flash the TWRP, but got "'flashboot' is not recognized as an internal or external command". I am still in the directory where I downloaded flashboot and this is a new error..
I then started on the instructions in post #5, all the way up to "fastboot flash zip fw_6.12.61.4.zip" but I get the same "...not recognized..." error. My phone is now on a screen similar to fastboot, but there is just the one option, "RUU". It was on a black screen with "HTC" in the middle a moment ago when I was trying to flash the zip.

@MonkeyBrains7532
What do you mean with flashboot? Or is this just a typo? There is no flashboot command. The basic idea is:
fastboot flash recovery NameOfRecovery.img
You can also only boot into TWRP with fastboot boot NameOfRecovery.img
If you want to try to flash only the firmware first you need to lock bootloader first. I'm not quite sure if you should be on stock recovery for that. You can flash that one as well with the mentioned command

So I continued off where I left, firstly by putting the phone in flashboot mode then repeating step 4 on post #5.
However, when I ran "fastboot oem rebootRUU" in cmd it just sat on "<waiting for device>" until I killed the command.
Is this just a question of leave it alone for a little while?

Was USB debugging enabled on your phone? Seems like it wasn't. Does it say in hboot fastboot USB?

Well then it's not working. It either should say fastboot USB or fastboot AC. It's been a while as I've done that, so I'm not 100% sure what it should say. So you need to go the route with twrp backup instead. Can you at least flash or boot twrp?

I am getting "waiting for device" when I run either "fastboot boot twrp-3.1.1-0-m8.img" or "fastboot flash recovery twrp-3.1.1-0-m8.img".

I should do. Next step, go to recovery?
Fyi, I scrolled down in Fastboot and the menu name changed to Fastboot USB. Tried booting and flashing again, but still waiting for device. I don't know if this new information changes anything.

Try to flash stock ruu, if isn't working it's probably a dead nand.

Black screen with red triangle is the stock recovery. So that is expected. Hold vol up, and press and release power button, to show the stock recovery menu options.

That message is expected when trying to flash custom recovery with a locked bootloader. TWRP is only going to flash if the bootloader is unlocked.
Since you are s-off, you can also try the following method to unlock the bootloader: https://forum.xda-developers.com/showthread.php?t=2708571
However, I agree with the previous reply, given the random bugs and behavior, it is best to RUU to a full stock factory image. RUU will wipe the phone, but it sounds like you are trying to wipe user data, anyway. You have the Sprint version M8, and the correct RUUs are here (do not try RUU for any other M8 version! permanent damage is possible):
https://forum.xda-developers.com/showthread.php?t=2729173
You can try any of the RUUs there. But note that if you try the Marshmallow RUU, you will have to flash corresponding Marshmallow firmware.zip before the RUU will install properly (this is clearly indicated in red caps text on the linked thread).
I also agree with the previous response. The behavior is really suspicious (changes don't "stick", bootloader does not unlocked) and NAND failure is a real possibility, especially if the problems persist after RUU.

I'm on 4.4.2 which one should i use (the non-HK i guess since my modelid is 0P6B70000) , i really want the easiest and most detailed way to flash the RUU
and sry for asking this (Do i just unzip the RUU and install or some codes are involved) cuz i downloaded RUU_M8_WHL_L50_SENSE60_SPCS_MR_Sprint_WWE_4.25.651.14_Radio_1.09.20.0209_NV_SPCS_1.52_003_release_426232_signed_2.exe
and installed it but nothing happened
also i wanna mention that this phone came from china and i read abt this Region\carrier codes so maybe while someone trying to fix it change it to Sprint[US] (dk if that is possible) (i'm just guessing i dk if we could use this information)
and Huge thanks to you

Both HK and non-HK versions have the same model number 0P6B70000. The only different is in software/firmware.
Your OS number in getvar (3.30.651.2) leads me to believe it was originally non-HK (the "651" signifies this). But it's possible that the previous seller changed it from HK to non-HK (although I'd say that is unlikely).
Really since you are SuperCID, either RUUs will work (HK or non-HK). You can try 3.30.651.2, or the one you downloaded 4.25.651.14 is fine as well.

The .exe format RUU is probably the simplest method. PC is required.
Do not unzip or do anything special to the RUU. Connect the phone to PC, with phone in bootloader mode. You should be able to just double click the exe file, and it should launch the application, which just walks you through the installation.
Are you saying you double clicked the exe file, and nothing happened? Or that it fully installed, but the phone is in the same state?

No, that isn't possible. The Sprint version M8 is different from all other versions. Trying to flash Sprint version firmware/RUU to any other M8 version results in a radio brick (no SIM, no cell service).
We see on this forum a lot of folks with the Sprint version M8 which have been made s-off and SuperCID (by seller/vendor) to unlock them for use in other countries, and to appear "unbranded" (when they are in fact, far from it).

your Help is much appriciated

It did nothing bcuz phone was on bootloader menu but when i tried RUU while phone was booted , wizard moved on to the next step ,
wizard tried to flash RUU but it's stuck on waiting for bootloader , and instead of the phone boot into bootloader it just reboot into the same restore point as if nothing happened.
-https://onedrive.live.com/?cid=AC7BFAC4E523EA2B&id=AC7BFAC4E523EA2B%21340&parId=root&o=OneUp
- it kinda does that in every process before last step (rebooot) , I tried
1-Flash Firmware via Hboot (requires micro sd card)....
-rename firmware to 0P6BIMG.zip
-copy 0P6BIMG.zip to ext_sd card
-boot into bootloader
-make sure hboot is highlighted, press power button
-it will scan your ext_sd card, then ask if you want to start the update
-press volume up & let it do it's thing...
*reboot after pressing up
2- Flash Firmware via fastboot, no ext sd card needed....
-rename firmware to firmware.zip
-copy firmware.zip to your sdk folder
-boot into bootloader
-plug in usb
-select fastboot option (screen should say fastboot usb)
-type fastboot oem rebootRUU
-when u see the black screen w/ HTC, type fastboot flash zip firmware.zip
-when it's done, type fastboot reboot
* Reboot regularly after fastboot oem rebootRUU
3- ARUwizard to flash 3.30.651.2 stuck at same point (waiting for bootloader) then phone reboot regularly
Is there any other way to flash
