quick question.

do I have to flash the latest sprint firmware before installing Viper ROM 6.0.0.
[Sprint HTC One (M9)] Kselle04:
Damn bootloop

Wondering if you guys could shed some light for me. My wife has an M9 fully stock. Locked and s-on. It started bootlooping on her. When I try to go into RUU mode it's a constant loop. I can access download, bootloader and recovery no problem. I tried flashing the RUU with the SD method. It starts then reboots. Tried a couple different SD and downloads verified. Does she has toasted hardware?
[Sprint HTC One (M9)] OMJ:
maybe try using the exe version of the RUU, if it still wont boot, I'm not sure what else it could be besides hardware...time to call HTC support or Sprint if u have TEP
[Sprint HTC One (M9)] GUNITJHAE:
Infinite Boot Loop

I'm having the exact same issue as your wife. I pulled my phone out of my pocket to check it and boom, it's bootlooping. I can't boot into recovery, however. If you can get into recovery, I'd say try wiping the cache partition. If not, as stated earlier, try the exe version of the RUU. That should work. I'm trying to avoid it to save my data. Which RUU did you download? All of the ones i've tried from the first post on this page have given me some sort of "file is invalid" error, and i can't move it to my SD card.

Will these ROMs work if my phone is not rooted? I'm getting a bootloop and just want to access the OS to get the files from the internal storage.
[Sprint HTC One (M9)] jpwhre:
You can't put your sd card in another device connected to Wi-Fi download, and put card back in phone?
[Sprint HTC One (M9)] GUNITJHAE:
I actually ended up trying to flash the zip through adb/fastboot whilst the phone was in download mode. I extracted the RUU from the RUU.exe distributed by HTC and got a security error. I have no idea what to do at this point.
[Sprint HTC One (M9)] jpwhre:
If you can get device in download mode, Run the RUU whilst connected to pc in download mode. You're going to loose data, pretty much any thing you try. Unless you had usb debug turned on and can manage adb backup.
[Sprint HTC One (M9)] BodhiBrock:

[Sprint HTC One (M9)] OMJ:
none of the firmware I've posted should wipe data
[Sprint HTC One (M9)] Sumit Khuha:
So i can flash your firmware in download mode? And will not lose any data?
[Sprint HTC One (M9)] Sumit Khuha:
Is your firmware recovery flashable? Or i have to flash from download mode?

firmware is always flashed in download mode (or bootloader if s-off)

Trying to install Bad Boyz on a 3rd phone now, for a family member. I already unlocked the bootloader, and installed TWRP.

For some reason this one is really fighting me, not sure why! I've tried 3.41.651.4_signed_firmware.zip, and 3.41.651.41_full_firmware_ruu.zip

Any help on this would be greatly appreciated.

Relocked bootloader using fastboot oem lock. I seem to recall doing that before, but I don't remember where I did it.

I'm completely stumped. What do I do now?
[Sprint HTC One (M9)] jpwhre:
Yes, the fastboot command relock device. Do that again. Then don't flash any zip stuff. Run full blown htc ruu for Sprint that you download from htc support page, or Stock rooted rom from this thread and download pure stock 0PJAIMG to root of sd card (put card in different device and download as an option).

Either way of doing it will flash latest and greatest everything. Thus no need to flash any firmware.zip files later.

Unlock bootloader. Install twrp 3.1.0-0 and then flash this rom (or other rom of choice) thru newly installed recovery.
[Sprint HTC One (M9)] Blueraydude:
I will give these steps a try.

My concern is that the latest RUU is 3.41.651.41, and Bad Boyz says to install 3.41.651.4. Will this version difference cause a problem?
[Sprint HTC One (M9)] jpwhre:
Shouldn't at all. I'm s-off but I can test for you.
[Sprint HTC One (M9)] Blueraydude:
Ok, I went ahead and ran the RUU .exe.

It gave the following. "ERROR [155] UNKNOWN ERROR

The ROM update Utility cannot update your Android phone.

Please get the correct ROM Update Utility and try again."

Not sure what to do now.

Edit, I tried the ruu.exe again, and it worked fine. I will update if I run into further issues. I really thank you for your instructions. My hope is that it'll work out!

Edit again: I followed your instructions, and was able to flash ROM. Several Google apps are crashing on boot now. What should I do?
[Sprint HTC One (M9)] OMJ:
I don't think locking bootloader on s-on devices is required anymore...

[MENTION=4938167]Blueraydude[/MENTION] have you tried using the 0PJAIMG.zip method? I find it always works the best...

also, when using the fastboot method are u 1st using the cmd fastboot oem rebootRUU and flashing from download mode?

from OP....

Flash Firmware via fastboot, no ext sd card needed...

-rename firmware to firmware.zip

-copy firmware.zip to your sdk folder

-boot into download mode

-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
[Sprint HTC One (M9)] jazzdglass:
Hi. Thank you. I flashed the bad boys ROM stock rooted. I'm still getting the bootloops. Flashing went fine. No errors. I flashed with twrp. All I get is bootloop on the red text HTC screen

I'm getting more confused as I read posts on HTC threads. I'm coming from samsung where it was super easy just selecting files in Odin and flashing.

But here bad boys rom requires flashing a firmware before or after flashing the rom? I was on latest 6.0 before I tried to root and ended up in bootloop. Are there steps to take to flash OS to this phone either bootloop plz
[Sprint HTC One (M9)] Blueraydude:
I tried the 0PJAIMG.zip method, it didn't work. I am using fastboot oem rebootRUU.

Phone seems to work now, I used RUU .exe, and then installed rom. Gapps crashed, so I did factory reset, and it seems to be fine now, running rom.
[Sprint HTC One (M9)] OMJ:
what version twrp did u flash?

BB ROM doesn't necessarily require flashing firmware b4 or after, it depends on if your firmware is up to date, it should match the ROM version...so if the ROM is based on 3.41.651.41, your firmware should be the same.

being s-on, you can only flash signed firmware, which will overwrite boot & recovery (twrp)...you never want to flash signed firmware after flashing ROM, it will not boot....the boot.img is modified during ROM & supersu install, stock boot will not boot if the /system has been modified.

it's not too complicated...if you were 100% stock, u would follow these steps:

1. unlock bootloader via htcdev.com

2. make sure firmware is on latest, if not, update firmware or flash RUU

3. flash latest twrp

4. flash supersu or magisksu, or stock rooted ROM
[Sprint HTC One (M9)] jazzdglass:
I flashed latest twrp. after i unlocked bootloader. then flashed latest superSu. that was when bootloop started. i unknowingly wiped system .Now i have no OS. but i flashed stock rooted bad boys. and bootloop persists. I didnt do any special thing during flashing. i just flashed directly as i posted.
[Sprint HTC One (M9)] OMJ:
I know we had trouble with many versions of supersu after v2.65, but I thought that was fixed...the version in the stock rooted ROM appears to be SuperSU-v2.79-201612051815.zip, which I'm pretty sure someone verified was working. I know it was tested or it wouldn't be posted. You may want to flash the latest RUU & start over.
[Sprint HTC One (M9)] jazzdglass:
Thank you for the response. Now i have the latest RUU from OP. but its giving me LOW MAIN BATTERY POWER error[120]. battery was actually charged full. why this again? :confused:

what are the steps to flash RUU? I may be doing something wrong. Do i need to relock bootloader? sorry for being such a noob at HTC. samsungs were never this difficult. all i wanted was root.
[Sprint HTC One (M9)] OMJ:
I always prefer the 0PJAIMG.zip method, instructions in op, or use exe via pc
[Sprint HTC One (M9)] jazzdglass:
After many days of worries, I was able to fix this just by flashing a boot image boot.img from LeeDroid ROM. I think flashing any other boot image could have solved the bootloop issue too. So if you got issue with bootloop, try flash boot image from rom you are on with adb.

My bootloop problem started after I flashed latest official Super su via twrp while on stock rom. I flashed bad boys ROM and same bootloop persist at red text screen. Same issue with LeeDroid rom after I flashed. So that was why I flashed LeeDroid boot image which booted the rom properly. I had bootloader unlocked. Not S-off
[Sprint HTC One (M9)] Blueraydude:
I used the 3.41.651.41 ruu.exe and flashed Bad Boyz. Now the phone is crashing and keeps going back to the setup page.

How can I safely downgrade to 3.41.651.4? It worked fine on other phones. I just couldn't get fastboot to flash 3.41.651.4 this time. Will I have to S-OFF/Sunshine?
[Sprint HTC One (M9)] jpwhre:
Yes you need s-off.
[Sprint HTC One (M9)] Blueraydude:
Thanks, I will do Sunshine, and will try to downgrade to 3.41.651.4. I assume I can easily do so with Fastboot after S-OFF?
[Sprint HTC One (M9)] jpwhre:
I guess, I've never done a roll back on my m9. It was the easiest free way to s-off the m7 and tricking the device to roll back firmware to get s-off. On the m9 you need s-off to downgrade firmware. Not something I care to do if I don't have to. And I don't foresee a need to do so in the future either so I can't speak of experience.

Try, see what happens and report back. What's the worst that could happen?

Personal preference, but I would never do it. That said...

Google (search here at xda) process, side effects, pros, cons. Is it worth it?

What are you looking for in a rom? omj does great work even on stock rooted rom that is more up to date. The custom rom was great for the day, but dev no longer has a device to test with and that is vary important if you would like to see work continue on that rom.
[Sprint HTC One (M9)] Blueraydude:
I know that 3.1 of this rom is stable, and it's all I need. Family member needs their phone to work, I'm going to have to roll back to 3.41.651.4 as 3.41.651.41 does not work! I will report back after Sunshine to see if it works. Sunshine devs responded to my support ticket and claim I can roll back.. Fingers crossed, will report back.
[Sprint HTC One (M9)] OMJ:
FYI.. Nougat should be coming soon, you might want to try once more with the latest ruu.
[Sprint HTC One (M9)] Blueraydude:
How can I try again with latest RUU?

I went ahead and installed 3.2 version of the ROM. Still no boomsound, not sure if phone is rebooting/crashing, but no app crashes yet.
[Sprint HTC One (M9)] OMJ:

Attempted to flash the 4.27.651.4 RUU.zip from extSD, got Error 12, not sure why. Had to flash the 4.27.651.4 firmware package first, then the RUU flashed without issues.
[Sprint HTC One (M9)] OMJ:
good to know....I'm not sure what device I've seen this on b4, but I know I've seen it in the past...having to flash the new firmware 1st, b4 it would let u flash the RUU
[Sprint HTC One (M9)] Kisakuku:
Yeah, had happened to me at least twice on my assorted HTC devices, which is why that was the first thing I tried. Well, also tried the 4.27.651.4 RUU.exe, but got another error message, error 153 this time. Either way, got it to work after all, thank you for decrypting the RUU and for posting the firmware packages.

Another PSA: as I'm sure we all know by now the MM firmware zips should not be used to downgrade from N, only a full RUU (or at least a full firmware package pulled from an RUU and an appropriate ROM) should be used for downgrades.
[Sprint HTC One (M9)] ankurcshah:
Can I just flash this over the badboyz rom to get to stock rooted nougat?
[Sprint HTC One (M9)] retiredtrebor:
Yes, that is exactly what will happen. Make sure you do a backup. The RUU will totally wipe your phone, but not the SD card.
[Sprint HTC One (M9)] ankurcshah:
Okay . flashing it over badboyz ROM then. Thanks. I'll be sure to do a backup. I read about being on a nougat firmware first for flashing a nougat ROM.

---------- Post added at 04:41 PM ---------- Previous post was at 04:28 PM ----------

What I meant was flashing the stock rooted ROM zip in twrp over badboyz ROM, not the ruu file. I hope the process stays the same. Or do I have to run the ruu first???
[Sprint HTC One (M9)] OMJ:
1. what u read was flashing the new firmware prior to flashing the RUU

2. yes, flashing over BB ROM should be ok, but you 1st have to update/flash latest firmware

---------- Post added at 11:35 AM ---------- Previous post was at 11:15 AM ----------

So apparently you just flashed the Nougat ROM without updating firmware. That might be the reason why some apps are not working. Either way, you don't need to RUU and wipe the device to go back. You can indeed just flash an MM ROM.

[Sprint HTC One (M9)] Octeen:
I'm trying to upgrade from 3.41.651.4 to 4.27.651. I am s-off running ViperOne 4.3.0. I flashed the 4.27.651.4 one with removed recovery and boot, with the micro sd method. It booted but it didn't change my firmware. What path should I be taking, and what am I doing wrong? I did come across the below statement in one of the threads but I don't quite understand what I should do or if it applies to me. Any help would be much appreciated.

It seems like HTC changed its encryption keys between firmware 3.x and 4.x. Therefore, you cant flash 4.x RUUs if your phone is currently using a 3.x firmware. You either need to flash a NoWipe/Full-Wipe Firmware Pack beforehand (only possible with S-OFF) or you need to use a 3.x RUU for the same SKU and install the 4.x OTA, afterwards.
[Sprint HTC One (M9)] ccs86:
I am also struggling to update to N...

Phone is currently running Badboyz 3.2 on 3.41.651.4, S-ON, Unlocked.

I tried the RUU exe, but can't even get started due to a USB error 170

I decided to first flash the unmodified firmware using fastboot, and follow it up with the extSD method of flashing the RUU zip. MD5's were verified before proceeding. I errored out flashing the firmware (zip signature checking failed, among other things shown in the screenshot).

Any suggestions on how to proceed? Thanks!

:edit:

I just tried booting into the bootloader, using the fastboot oem rebootRUU command, then connecting to the computer and running the RUU exe, and it actually appears like it might work. I'm at the point where I can click the "update current ROM" button. But now I'm a little gunshy with the stories I've heard about needing to flash the new firmware first. Has anyone had success going from M to N, without manually updating the firmware??
[Sprint HTC One (M9)] Octeen:

[Sprint HTC One (M9)] chimpsinties:
Where are you seeing that is your firmware? In the Settings menu? The Settings | About | Software Information is showing what firmware the rom is based upon not what firmware your phone is actually running. I think the only way you can see what firmware your phone is running is via Download Mode but it's even possible for this to display the incorrect version under certain circumstances I seem to recall.
[Sprint HTC One (M9)] misfit0313:
If we are s-off, what do we flash from the sd card to get the N firmware? Do we need to run the whole RUU from a PC? The firmware only options says they are for s-on users only. Am I just interpreting the note wrong?
