Tmo Htc One M8 error 12 "Remote Signature verify failed"

I am fixing a TMO Htc One M8 for a friend. He currently has TWRP recovery but nothing will wipe or flash. I have posted the get var information and the log below along with all the steps I've taken, please share any insight into the matter.
Here is the Get VAR Information. I have tried to fix this device by relocking the Bootloader, flashing stock RUU RUU_M8_TMOUS_1.57.531.7 , Flashing modified firmware.zip, flashing recovery.img, nothing. Then unlocking the bootloader, flashing Philz recovery.img, Twrp.img, still same error. Current TWRP recovery registers nothing but errors. No wiping data, cache, system, etc. No installing backup nandroid, no flashing new rom through external SD card or adb sideload. Literally the phone won't flash anything and the error is error 12, "Remote signature verifiey failed" What kinda insight do you have into this? Anyway to get back to stock?
Thanks!

okay I'm wondering why the bootloader is 3.18. I just converted my T-Mobile HTC one m8 to dev edition and that's what my bootloader is now.
That device must have been s-off before if it has the 3.18 bootloader. the problem is now you're s-on with the wrong bootloader in the phone. So it's not gonna verify something it can't. U need to unlock the bootloader then try to s-off again. Let me know if u need more help

Yes, I think the device was S-off before was well. But how can I get the device S-off when I can't load any rom to establish an internet connection?
There's no way to get back to stock, or get an internet connection through the device to obtain S-off. I can unlock the boot-loader,
I've done that a few times, but how to get S-Off when the only two screens I can access are the bootloader and twrp? When bootloader is unlocked. I have used firewater before for S-off and it requires active internet connection on device.
Thanks again for helping

Unlock bootloader try to flash the latest open twrp recovery and try to install another Rom or backup. If you can see the roms in the sdcard then you should be able to flash the roms or backup.
If there was a way to get into adb YOU would be able to s-off again.

I've tried to flash TWRP but I get that error. I tried to flash the newest twrp but it wouldn't flash.
I think the system is no longer mounted, that's why I get this error :"E: Unable to mount 'data'" and "E: Unable to mount internal storage"

Is there any option in recovery to format? if so have u tried to format each partition manually?
Then try and see if it will flash. Just need something to boot so you can s-off .
You need to get s-off again so you can flash a ruu with lower hboot if formatting doesn't work or you can try to flash the new 4.4.3 ruu when it becomes available. They said the ota should be out on the 11th.
I'll keep looking for ways to s-off without adb .

Well first your doing the wrong command. Its fastboot flash recovery recovery.img, not fastboot flash flash recovery.img.

Yes, that was a typo. Every fastboot flash ends with error 12. Remote Signature.
I have tried literally everything with this device. Tried flashing new TWRP, Radio, Firmware, Etc. Nothing works.
Inside TWRP everything finishes with "failed" or "E: Unable to mount cache"
I tried to select cache under the mount in TWRP and it's greyed out. I fastboot erase cache, and it is literally
the only thing that worked for me. But still no way to restore previous Android. Tried flashing stock RUU's for 4.4.2 and 4.4.3, no dice.
Both RUU's get to 6 percent and then say failed. I'm wondering if the device thinks it's a different phone possibly a GPE edition so it won't
go back to stock? Just a thought. I have unlocked, and relocked the bootloader a million times trying different methods as well, not
sure what else there is to do next. This might be the end of the road for this customers phone.

Under TWRP the only option is to format data. I formatted, but it did nothing that I'm aware of.

I am able to flash Viper Rom though, but because it is S ON the rom won't boot past start up screen.

There should be a way now that the new T-Mobile update to flash ruu if we can find one.
Edit: found one
http://www.htcdev.com/devcenter/downloads/P00
Just select T-Mobile as carrier and USA as region then you Wil see the latest ruu to download.

the latest viper is from New firmware base so it takes 15 to 20 minutes to boot. Have you waited that long?

Sorry it seems I'm getting posts in different orders.
Flash viper and wait 15 to 20 minutes. And we can go from there.
I'm pretty sure we can get this resolved.

I'll try to flash the latest Viper. The 1.6.0 it says everything flashed correctly, but gets stuck at the HTC boot screen.
I just flashed the 1.8.0 OTA update and everything installs but it sticks at the boot screen.
I see the 2.2.0 update is out so I'm downloading that now, I'll flash and see how it goes.
I'll update, thanks for your help!

Ruu requires the bootloader be locked
Sent from my HTC One_M8 using XDA Free mobile app

[Q] [RUU] Error: 152. Unable to Restore TMob One M8

Hi, thanks for reading.
I was running the latest version of CM on my One M8. Decided I wanted to revert to stock ROM to regain HTC camera and wifi calling functionality. Figured an RUU would be the easiest way.
Here's where I probably screwed up. Downloaded and ran the RUU for ver. 2.xxx from HTC. Forgot to relock bootloader, but it rebooted early back into CM no problem. Relocked bootloader. Ran again.
I should have known to pause when I saw that my version was 1.5xx but it seemed fine with updating versions as part of the process.
Then it failed again, error 152. Was able to reboot into CM again this time.
I did some googling and reading and saw one guy say that he was able to fix by simply running the RUU again once it was in the "four exclamation marks in triangles" screen, which is where I was after the next try, so I ran again. Another error 152.
So finally I realized maybe I needed the 1.5xx RUU. DL'd that, tried running, "error, wrong version." Because now it thinks my phone is on ver 2.xxx.
Now I can't get the phone to boot into recovery or into bootloader. No clue where to go from here. I'd really appreciate your help. Gosh I screwed up.
The last lines in the RUU log (1.5xx) are:
Code:
<T205408><DEBUG><OUT>Execution time is 6(s)</OUT>
</DEBUG></T205408>
<T205408><DEBUG><OUT>FAIL43 main version check fail</OUT>

Update 1: can recognize device using "fastboot devices" but not "adb devices." haven't tried pushing/pulling anything yet. Saw someone in another thread tried installing via command line. Not sure which .zip I should use, as there are a ton of options on XDA, or if this is what I should try next.
Update 2: there are seemingly two versions of the "four exclamation points" screen: one is dim and has the orange led showing and the other is bright without led. Bright without LED is what I got after "flashboot reboot-bootloader". Worried that the bright one may deplete battery.
3: Since I can't otherwise boot into a recovery, should I try to flash a recovery?
4: Not sure if this is useful but:

9: Used a zip repair to repair those RUU .zip's. Noticed that their android-info files have "hbootpreupdate:12" but my phone has "hbootpreupdate:11" might that be an issue?
Sad Edit: I tried some stuff, nothing seemed to work. Freshly downloaded from an alternative mirror the 2.2xx RUU and booted into RUU via fastbooth before running it. Everything said it went perfectly "CONGRATULATIONS ROM UPDATED! Rebooting!" etc.
My phone is bricked. Never woke up from that reboot. My computer keeps trying to recognize the device via usb, but nothing.

I didn't think you could use unsigned zips with s-on. Also you couldn't flash stock recovery because your boot loader was locked. If your boot loader wasn't locked it would be worked. So it doesn't show anything in fastboot anymore? Have you tried charging it them plugging back up to computer to see if fastboot will recognize it again?

Yeah I tried unlocking the bootloader while fastboot was still recognizable, but it wouldn't work.
Not sure about the unsigned zips thing. Would that also go for the RUU? I thought those were signed/straight from HTC.
I'll try it once more, but it should have been fully charged last time I gave it a try. Computer shows an intermittent "QHSUSB_Bulk" but not sure where to go from there. Found threads for other HTC phones and tried their methods, but it got to the point where the one guy was supposed to go through Ubuntu to manually install individual .imgs to the phone, but I think he had somehow managed to get fastboot to work.

Ruu is straight from HTC they are .exe files. If it is an ruu.zip I think that only works with s-off. Hm I'm not sure what do to either, I was thinking maybe it just needed to force reboot then press power and volume down for hboot/fastboot I don't understand why it wouldn't just reboot.

Yeah it's especially weird because I thought with S-ON it was supposed to be hard/impossible to override ?boot.ini (not sure, don't quote me on that) anyway. But yep, won't boot at all.

M8 frozen system

Hello all,
I have an interesting problem with an HTC M8 from AT&T. It is completely stock only with OTA updates.

Now the interesting part. Every time the phone reboots, it is always in the same state as if the partitions were frozen. That is to say for instance if I uninstall an app and then reboot, the app is there again. If I connect to a Wifi network and reboot, it disappears. Every single modification is erased and returns back to the same state. The most annoying thing is that when I connect to a Wifi the apps start synchronizing, crash and the phone reboots.
I tried the following:
- Factory reset from the interface to no avail as it returns to the state it was as well
- Factory reset from HBOOT reboots into recovery with a red triangle with exclamation mark and stays the same
- Downloaded the RUU from HTC, which reboots the phone and then stays the same and reports an error
- Tried "fastboot oem rebootRUU", which simply reboots the phone into android
- Tried to unlock the bootloader, which again reboots the phone into android
- Tried to flash a different recovery and ends up with error: FAILED (remote: signature verify fail)
- Tried to flash only the zip from the RUU and ends up with the same signature error
I simply can't think of anything else to do, and I hope one of the gurus can help me in my quest
Thank you for the time you spent reading my post.

I have an interesting problem with an HTC M8 from AT&T. It is completely stock only with OTA updates.
(bootloader) version-main: 1.58.502.1
It doesn't appear to have had any OTA updates. Or at most a minor update from 1.54>1.58.
- Factory reset from HBOOT reboots into recovery with a red triangle with exclamation mark and stays the same
Try pressing vol up and power to show the stock recovery menu options. I believe factory reset is one of those options, although if wiping in OS didn't work; I doubt doing so from stock recovery will be any different.
- Downloaded the RUU from HTC, which reboots the phone and then stays the same and reports an error
Which RUU (exact filename)? There are many, and the RUU has to be intended for your CID version.
What error number, and what error message? This is very important, otherwise we have no idea why it failed.
You're on the right track, by trying to run an RUU. I think its your best bet to fix the issue. But we need to make sure you run the right RUU.
- Tried to flash a different recovery and ends up with error: FAILED (remote: signature verify fail)
You can't flash recovery with a locked bootloader.
- Tried to flash only the zip from the RUU and ends up with the same signature error
Again, which RUU specifically is very important. Can't tell if the RUU is the right one based on the info given.
Also, please verify on the hboot screen, near the top, if it says LOCKED (other possibilities being UNLOCKED and RELOCKED)

Thank you so much for your reply.
I have tried the factory reset from the recovery and the result is the same.
I downloaded the latest RUU for my model I believe:
RUU_M8[email protected]50319A_40.45.C33065.00_F_release_446225_signed_2
The update states it will upgrade from 1.58.502.1 to 4.28.502.2. Then I click the next button, the phone reboots and the updater says "waiting for bootloader", however the phone booted into android just like when I issue the command "fastboot oem rebootRUU". The installer then fails with error 171: USB connection error. I attached the RUU log as well.
The HBOOT says *** LOCKED ***. I tried to unlock it through the HTCdev process "fastboot flash unlocktoken Unlock_code.bin" but the bootloader stays in the same state.

Yes, this is for your model (AT&T) and the version number will work.

This is means there is a USB communication issue, usually on the PC side, and there is nothing wrong with the RUU or the phone.
RUU is very finicky, and this issue is common. Try a different cable, different USB port, and try to re-install HTC Sync.
But you may have to resort to using another computer. Win7 and USB 2.0 (USB 3.0 is known to cause issues with RUU) are the best bet to get the RUU to run properly.

Do not unlock the bootloader if you intend to RUU. Unlocked bootloader will actually cause the RUU to fail, by definition. RUU requires the bootloader by LOCKED or RELOCKED (or else you need s-off to run an RUU with the bootloader UNLOCKED).

HTC m8 not starting up correctly. Tried everything i can think of and find.

Hello there!
I have now searched and searched and come upon many great threads in this massive forum however i have yet to find a solution to my current problem. Every time i have went here i have always managed to find something to help me fix my phones over the years but this this time I've hit a wall it seems.
What happened was that my phone started to crash the google apps like gallery etc. No big deal at first but then i decided to do a factory reset thinking that might fix the problem but then my phone just starts up to the HTC logo and throws several different error messages that Google.xxx.xxx could not start/has crashed. IF i click these away they appear after a while again and the phone will be stuck like that.
I can start the phone in fastboot mode to be able to use ADB etc..
The phone is currently bootloader unlocked and with S-on
Now this is what i have done:
First of all the phone wasn't in debugging mode when it crashed so I'm guessing its still not which might complicate the matter further.
* Using a TWRP.img file i managed to get the phone in to the TWRP mode on the phone. (Fastboot boot TWRPfilename.img)
I do not have any TWRP files on my phone nor any apps this was all from the files on the PC. I just mention this because thats the only sign of life the phone has given me so far.
*I tried to go in from the adb shell and enabling it using the following code:
Adb shell
echo "persist.service.adb.enable=1" >>/system/build.prop
echo "persist.service.debuggable=1" >>/system/build.prop
echo "persist.sys.usb.config=mass_storage,adb" >>/system/build.prop"
reboot
I have no idea as to if it worked or not but the phone rebooted again.
* Tried to reflash with the right RUU for my phone with the right CID thanks to guides on this forum -- i get error 159 (this is because the CID is wrong from what ive read in other threads)
* Tried changing the CID to 11111111 but that did not work i got another error doing that:
C:\adb>fastboot oem writecid 11111111

* Tried flashing from a .zip file with the fastboot commands.
ALL of these things I have tried with the bootloader locked and unlocked. (if this is any important info)
The phone ran the 6.12.401.4 version at the moment of the crash and that's what shows in the RUUs ive tried as well. Also the phone is not rooted.
Now is there a way to completely flush the phone out of any info and just reinstalling it like you can do with windows on a PC for example since whatever i try is met by an error message or a failed flash etc..?

oh! ive done goofed!
It was my bad with some **** spelling there.
IT WORKED!!
I thank you sooooo much from the bottom of my heart I was sure my phone was unsaveable for a moment.
what was the difference with that RUU and the ones I've tried before? I must have tried like 4 different ones in the end out of desperation.
or was it the fastboot that was the trick?
I'm just curious on how you could spot the problem so that i can learn more about how it works.
Thanks again! Truly great work!

We can't say if the RUUs you tried were correct or not, as you didn't give any specific on those (file names, where you found them, etc.).
But you do need the htc_fastboot to run the RUU.zip with fastboot command, the "generic" fastboot.exe does not work.
And you absolutely need to have a LOCKED or RELOCKED bootloader to RUU with s-on (this requirement is bypassed with s-off). So you were also compounding one wrong thing with another (when trying to flash RUU with bootloader UNLOCKED) making it even less likely you would have the successful combination of variables.
Unlocked bootloader is okay to OTA, so that is where I think some folks get confused on when to have the bootloader locked or not. But OTA and RUU are two very different things (with different requirement), and its important to remember that fact.

I think this is where all else failed since all the ones i tried had either the ADB or a file called only Fastboot.exe not this one that said HTC_fastboot.exe

That still doesn't tell me much about what RUUs you tried. What are the actual file names, version numbers, etc.?
Only if you are still curious why the RUUs didn't work, of course. I understand its somewhat of a moot (or purely academic) point, now that the phone is working.

Somewhat as I figured. All those RUUs failed for good reason.
First and second ones: These RUUs are older (lower version number) than the main version that was on the phone (6.12.401.4), otherwise known as a "downgrade" in version. With s-on, that isn't allowed. You can only flash the same or higher version (later) RUUs; and the only way to bypass that requirement is with s-off.
Third RUU: As you know, this isn't for your phone. You can run it a million times, and it will still fail every time; as its intended to fail since the CID and MID on your device doesn't match what the RUU is looking for. The only way to run this RUU is to s-off and change your phone's CID and MID.
Forth RUU: Again, not for your phone. Plus, the Sprint version, which has partition differences from your M8 version (and most other M8 versions). You absolutely should stay away from any Sprint or Verizon firmware, as if they do manage to flash, will often lead to a radio brick on your device.
This would never flash anyway with s-on, and the safeguards of the CID and MID did their job and saved you, in this case.
So in short, you can only run RUUs that have the "401" in the spot x.xx.401.x as these are for your CID and MID. And you can only run versions equal or greater than 6.12.401.4, of which there is currently the only one (the one that worked - 6.12.401.4).
Hope that clears things up a bit for you.

Yes indeed this cleared up most of my suspicions as well as i said i knew the 3rd and 4th was wrong from the get go it was more of a test..
Thank you for all this good info i feel like im starting to get a good grip on whats good and whats working etc... I really appreciate it! Thumbs up indeed.
I have another question tho.... Why would it not let me change the CID to the supercid 11111111?
IS that due to the phone not being in debug mode or the S-on option perhaps since i know that is a security feature from the get go.

Thanks! :fingers-crossed:

HTCDev is not a process to get s-off. It is a process to unlock the bootloader (but you say it's already UNLOCKED). Sunshine is the only valid method to s-off. You can try anything else a billion times, and it will never work.
You most likely also do not need s-off to get the phone working properly again.
I have a feeling that no sound is due to outdated firmware, possibly in conjunction with a custom ROM (ROM - firmware mismatch).
My suggestion, try to relock the bootloader (command: fastboot oem lock) then the following RUU:
http://gsm-firmware.com/index.php?a=downloads&b=file&id=14070
The RUU will wipe all personal data on the phone.

"Signature verify fail" usually means the bootloader is unlocked. Did you relock the bootloader as I advised (mandatory in order to install the RUU)? Or if you did, can you verify is says RELOCKED near the top of the bootloader screen?

Good point, and makes sense, as most of the US M8 variants require firmware to be flashed for Marshmallow RUU. Even though Rogers is Canadian, that version tends to follow the same rules as the US versions!

Hard to tell exactly what you tried to do here, since you didn't include the actual command, name of the file you tried to flash, etc. Always include as much specific info as possible. "install a rom" is not sufficient info.
You tried flashing a custom ROM over fastboot? If so, that isn't the proper way to flash a custom ROM. You need custom recovery (TWRP) to do that. So that is the reason for "not allowed" (since it isn't).
But before doing so, we should look closer at the RUU (why it isn't booting) first. Since installing TWRP requires unlocking the bootloader, etc. Better to eliminate the RUU as a solution first, so we don't have to keep going back and forth unlocking/relocking bootloader.
Did the RUU finish successfully without any errors? If there were errors, what did it say specifically? If you don't know the answers to those questions, you can run the RUU again. Even cut/paste the output so we can look at it.
