Can I downgrade a Verizon HTC 10 that has nougat to marshmallow by flashing the marshmallow RUU? I bricked my previous phone trying to downgrade with MM RUU (verified md5) because it blew through some error message about hboot (90?) that I couldn't stop, and it was bricked. Is there a way to prevent that from happening again? Do I need to flash a different firmware first?
Thanks!

Are you S-Off? If so, you can downgrade from N to MM
Downgrading from Oreo (which Verizon hasn't got yet) will cause a radio/baseband brick though

the reason you bricked is because you probably did what i did with my previous 10 and you have to downgrade using the full ruu. not just the firmware. also you have to use a specific htc fastboot driver to prevent blowing past that error. Googles fastboot driver does. its all in one of the ruu threads
You can not downgrade without s-off
sorry, maybe I wasn't specific enough.
The previous phone was s-off unlocked phone, supercid, had installed Verizon RUU. I was downgrading via booting into download mode and installing the RUU from my external sd card. I don't remember if I installed a different firmware before this.
Now I have an S-off Verizon HTC 10 on Verizon network, want to downgrade due to issues with keeping everything systemless to avoid breaking Verizon advanced calling features (my understanding is that if I modify anything in /system, like using an auto start manager or freezing bloatware or new kernel, these will break).
Should I be able to downgrade RUU from the external sd card through download mode without hboot issues? Or is there a way to check if there'll be an hboot issue? Doing it from adb on a computer would hopefully give me the option to rescue it if I get that error again, so it seems like the safest method. Or would flashing MM firmware first, then MM RUU, be the safest? I'm trying not to brick a second device. Thanks!

Yes, just put the Verizon ruu you want on your sd card and run as usual. No issues.

Hey guys,
So I'm trying to help my friend apply the OTA update to his M9. Currently, his phone is on firmware 2.11.617.15, which is a developer firmware I believe. But somehow, he converted his unlocked S-OFF phone to S-On which I know makes things more difficult. I've tried numerous methods on this website such as flashing TWRP backups and trying to flash stock recoveries from HERE but I've kept getting errors saying unable to read the recovery afte rebooting. Another method I've tried is trying to update the RUU via adb using htc_fastboot commands but I'll keep getting errors such as error 19 and error 22. Any guidance will be appreciated, thanks in advance.

Try sunshine again, it might work. Each phone has a license when you originally run the program

I know the best solution is switching the phone back to S-OFF, but I am sure that the only way to do that is to pay money and I'm trying to avoid that. I believe I read somewhere that S-ON just restricts the M9 from being downgraded, so updating shouldn't be a problem on S-ON correct?
If you are S-On then you can't update to 6.0 MM until the carrier releases the update.
If you S-OFF then you can update to the 6.0 MM

I recently bought an Unlocked HTC one M9 from eBay. It was on Android 5.0.2 (1.32.617.6) and I received an update notification for 1.32.617.30. When I clicked to install it, it fails saying error in cache with error 7. I think since it's a used phone the device software has been tampered before therefore the OTA update fails. I don't know the device history.This is what I found in bootloader mode.
Software status: Official
S-OFF
Bootloader:Locked
It is super CID (11111111)
And it has stock recovery.
I have tried flashing 1.32.617.6 stock ROM from stock recovery after I found it on XDA. It also failed saying signature verification failed. I searched this forum and found that someone had the same issue and they had to flash 1.32.617.6 using a SD card formatted to FAT32. I don't have a SD card so I couldn't try it.
I also tried HTC's latest RUU. EXE for Unlocked/Developer edition but it doesn't run well. It starts and shuts down after it asks me to agree to terms and conditions. I have latest HTC sync manager and it recognizes my phone. I will be trying this again on some other computer.
I really want to update my device to the latest version of OS. Please help me! I don't know what else to try.
You cannot flash an ruu because the device is modified. The easiest option is to flash an unsigned update. Unlock your bootloader and enable usb debugging first though.
Beamed in by telepathy.
I don't understand in what way the device is modified because it says bootloader Locked not relocked and everyrhing is stock. I thought it might have been restored to stock after rooting or what not. If that is the case shouldn't I be able to install OTA update?
Anyways I wanted to know if there is some way where I don't need to unlock bootloader or root it. I want to stay on stock OS.
Update: used RUU.EXE on Windows 7 computer and it worked. For some reason Windows 8/10 is not good with running external exe files.
I have an HTC One M9 that up until yesterday had an unlocked bootloader and had S-Off.
It was running a pretty old ROM so I decided to update it. My first attempt was Viper.
After installing through TWRP recovery it would only take me to the TWRP boot screen after rebooting.
I attempted another ROM, this time Revolution and got the same results.
I’ve been messing with it for hours and somehow I have S-ON and the bootloader is locked. Actually it says RELOCKED.
It has no OS and it will no longer go to Recovery mode. I think the TWRP I tried to install is too new for it.
I’ve performed the HTC bootloader unlock procedure a few times and although it says successful, after reboot, its still relocked.
Am I screwed, or is there something more I can try?
If bootloader is looked, the only solution is to try to flasher the latest ruu according to the model of your M9. It goes into downloading mode??

Yes, it goes into download mode. I've tried the only Telus ruu I could find (RUU_HIMA_UL_M60_SENSE70_ATT_MR_NA_Gen_Unlock_3.35.617.31.exe)
and I get a Error 131 Customer ID Error.
I just tried a Sprint ruu (RUU_HIMA_WHL_M60_SENSE70_SPCS_MR_Sprint_WWE_3.41.651.21.exe) and I got Error 155 Unknown Error. They both fail right after it displays Updating Signatures.
I'm in Canada and it's a Telus phone but it's carrier unlocked.
Do I need to use a Telus RUU or should any Canadian RUU work on it?
are you sure yours already s-off?
1. re flash lastest TWRP
2. flash required lastest firmware (s-off)
Firmware 3.35.401.12 is required for proper installation! Download (S-OFF ONLY)
3. flash your fav lastest custom rom
Yes, it's definitely S-On.
Any Canadians out there? After some reading I realize I need an RUU of a specific sku. In my case 661.
I need a Telus RUU of 2.11.661.5 or higher for the M9. I'm hoping that will resolve my issue.
Good Evening Helpful People,
I'm currently in a predicament with my M9 Dev Edition on trying to upgrade to the latest Android 7 firmware...
I forgot to make a stock backup using TWRP while S-Off to restore a factory state to use the RUU.exe from the HTC site, and I'm having troubles upgrading to 3.35.617.31 to have the "base" to take the 4.14.617.6 RUU.exe successfully.
**I'm currently on 3.35.617.21
*I understand how to change my CID and MID with S-OFF
*I can not find a stock 3.35.617.21 recovery.img to allow the RUU.exe to work
*I have no intentions to turn my S-OFF to S-ON
*I'm un-rooted "TWRP Backup Save" (No SuperSU) with TWRP as my custom recovery
*I can re-root whenever needed.
*ADB and Fastboot drivers are totally fine
I know that there is probably 3 or 4 different ways to go about my problem and I like to be resourceful on my own, but I would super appreciate it if someone here would lead me on the right track!

I'm a little confused - what problem are you running into with the Android 7.0 RUU (4.19.617.1.) from the HTC website? A non-stock recovery shouldn't be an obstacle to using a RUU. Assuming you're not worried about your phone being reset to factory*, you can use the RUU executable or install it via the SD card method.
I'm still learning, so maybe I'm missing something obvious - please let me know.
* As you know, your internal memory is wiped and your phone returned to stock system & recovery - but I'm pretty sure you don't lose S-OFF from RUUs. I've used RUUs several times since getting S-OFF and still have it.
Solved.
I flashed the 3.35.401.12 RUU according to Flippy498's guide
https://forum.xda-developers.com/one-m9/general/stock-nand-backup-ota-update-collection-t3132698 (Thread #5)
All the Phone data was wiped during the process.

Hello,
My friend's HTC M9 got bricked during the new Nougat update (was turned off during update).
Ever since it is bootlooping, in can put it in Bootloader and Download mode but can't load it to recovery mode.
Tried to flash the stock recovery via download mode but the phone is S-ON and locked.
What are my options in getting the phone back to life (gave up on saving any of the data on the device)?
Any help will be appreciated.
P.S.
First time handeling HTC but have a lot of experience with nexus devices
Device info:
HTC M9 himauhl
S-ON,
Locked,
OS - 3.35.401.32
You need to run the ruu.exe but I don't know if one exists for your version. You can flash any 3.35.401.xx ruu but those that aren't "xx" must match. Not sure you can flash a signed zip in s-on state..
If the ruu.exe doesn't exist then you'll either have to wait for it to be released or rtm for repair.
There is no actual way to know exactly how buggered the phone is because it died in the middle of a flash process. It is very possible it died just as it was flashing recovery, explaining why there isn't one, but I wouldn't like to bet money on it, or it being recoverable at all.

You've access to download mode, so you should be able to use the SD card method of applying the matching RUU. Check out the readme thread for instructions and the necessary file.
Thanks for your help shivadow and computerslayer,
I will look at the RUU method and try to learn more about it and replay if it worked or not.
I have the same problem and have tried everything but it's still bricked. If I send it in for repair will they charge me? My phone is out of warranty (it's 1.5 years old). Since their update caused this problem you would think they wouldn't make me pay. Thoughts?

If you unlocked bootloader, the warranty is void anyway.
Try flashing the stock rom which doesn´t need a unlocked bootloader via htc_fastboot.exe. Place the stock rom in your sd-card. Then in bootloader it will say directly "Do you want to flash xxx.img".

Those are two different methods: The SD card method and the htc_fastboot method (which requires a PC).
And it's actually the other way round. The htc_fastboot method requires a locked or at least re-locked bootloader whereas the SD card method can be used with an unlocked bootloader, as well.
