skydragon rom - stuck at boot screen

I have an AT&T HTC One M8. It was already rooted when it bought it. Running stock 4.4.2
I have installed the most current version of TWRP. I created a successful backup.
I am trying to install the ROM for skydragon 5.5 but it just gets stuck on the startup screen (white android screen)
I am S-on.
I flashed (via fastboot) the boot.img from the Skydragon 5.5 Rom.
I installed Skydragon 5.5 Rom from the TWRP install screen.
(note - these are the instructions from skydragon website and it states I do not need S-off as long as I flash the boot image)
When I reboot it just hangs on the startup screen (white android screen)
I can recover to get back to a working phone but I would really like to upgrade to skydragon. I have been having constant problems with bluetooth headsets on the stock 4.4.2 and am hoping the newer skydragon ROM and boot.img would resolve the poor bluetooth sound quality issues.
Any help would be appreciated.
Thanks

You probably need to update your firmware/hboot.

As mentioned, you need to update your firmware.
Current ROMs won't run properly (extreme long boot times, broken WiFi) on old firmware (hboot, radio, etc.).
Plus, the current TWRP will not flash ROMs properly on the old hboot.

I dont fully understand why but I lost my backup during my installation of the new skydragon ROM. The backups were on the SD card.......and then they vanished.
I did manage to barely avoid bricking my phone. I re-locked my phone, installed the HTC RUU for lollipop and got my phone back to working. I had been trying to use sunshine S-off tool so that I could upgrade the firmware but I couldnt get my phone to boot up to perform the S-off installation process.
I still want to install skydragon. These are the steps I think I need to take.
1. unlock/root my HTC M8
2. Install TWRP
3. Backup my phone
4. install the new Skydragon Lollipop ROM
* note - I assume that I dont need S-OFF since my firmware should have already been upgraded when I installed the HTC Lollipop RUU.
If my phone is S-off will the skydragon lollipop ROM installation automatically install the firmware? Or is that a separate installation?

1: You lost all because you ran a RUU !
2: A custom rom NEVER changes the firmware

To confirm whether the firmware was updated or not; what does it say on the hboot screen for hboot number, radio baseband, and OS number?

Flashing a ROM never updates your firmware. The firmware partitions (hboot, radio, WiFi, Bluetooth, etc.) are not included in a ROM zip.
Firmware flash is done as a separate action, usually via fastboot.

Actually I lost my backup before I installed the RUU......otherwise I would have reverted to my previous kitkat installation rather than installing the RUU and losing all my data. I know the RUU basically reimages all the memory.
I was using sideload to install the skydragon ROM. I suspect I did something wrong during one my fastboot flash commands or the adb sideload commands.

Need HELP please!!

Hi, i'm from Mexico (Telcel) and i have the international version of the m9.
Here is what i did:
My phone was on version 5.1.0 (stock ROM) and i unlocked the bootloader, flashed newest 2.8.7.0 and SuperSU then wiped and restarted the phone, everything seems to be fine so far.
The problem started after i tried to install Viperone m9 with Android 6 custom ROM.
When i install Viperone 4.2.1 everything seems to working fine but after restarting the device it goes straight to the fastboot menu (the one with the "Software status: Modified") but wont boot the OS (same happens with the ARHD version 20.00)
I'm very worried, i hope you guys can help.

You can't flash Android 6 on a M9 with Android 5 firmware. Either you use the Android 5 versions of the customs roms you like (e.g. Viper One M9 3.5) or you wait for the official Android M OTA to get distributed or you get S-OFF via Sunshine and flash one of the already existing Android M firmwares (whether it's an official from a different SKU or an unofficial one doesn't matter).

If you don't want S-OFF, just flash Android Revolution HD 14 (Lollipop 5.1) and wait then for official OTA in your region to get new firmware on your phone and flash a Marshmallow Sense rom. It shouldn't be so long anymore

What would be the best course of action in this case? what would you recommend? should i do S-Off in Sunshine or stick with ARHD 14.00 in the meanwhile?

It actually depends on your patience. I don't know the distribution date of the Telcel update but the European one is said to arrive this week. If you can live without Android M for a bit longer then I would recommend using ARHD 14 or Viper 3.5 until Telcel distributes the update.

The only reason to get S-OFF is to be able to flash a 3.x firmware before the official one arrives in your country. Whatever the rom you're installing, if you haven't got any patience anymore, it will let you install a 3.x firmware from another country but you'll have to pay 25$ to Sunshine for it.
For me, waiting some days more with Lollipop (without to pay for a Sunshine licence that will be usable only with the unlocked device) will be the solution.
After that, returning stock, receiving firmware via OTA and flash Marshmallow Sense custom rom (ARHD 20)

I think im going to need some extra help, i forgot to mention i fully wiped the device and then installed viperone without creating any backups of my stock ROM, i think im in trouble, i hope there is a way around this. Thanks for the help.

That's not a problem. You installed ViperOne! So that means you have a custom recovery and you're smartphone is rooted, that's enough. Which recovery did you install? With TWRP recovery you can plug in your smartphone to your pc and mount the sd card on your computer. You download ARHD 14, you copy to your sd card and install it with TWRP. Your smartphone will take more time to boot for the first time after that.
Is it enough clear for you like this?

HTC one m8 Skydragon Rom stuck on boot

Hi I just tried to flash Skydragon 4.0 on my bootloader unlocked, supercided with S-OFF one m8 running latest MM GPe firmware. The installation completed successfully but it gets stuck on the Google splash screen.
Does anyone know why this is? Do I need to be rooted? My recovery is TWRP 3.0.2

You shouldn't install any Sense based ROM on GPE firmware, won't work.
Sense based ROM requires Sense firmware. GPE system partition is too small for Sense based ROM.

When I tried flashing the Skydragon sense based firmware TWRP couldn't mount my internal storage, cache, system or data. Do I need an earlier version of TWRP or is it something else that's causing it?

I don't really understand what you're trying to say.
There is no Skydragon sense based firmware, only Skydragon sense based ROM.
Firmware and ROM are two different thing.
Are you saying you tried to install firmware.zip with TWRP ?
If yes .. this is wrong. You can't install firmware.zip with TWRP, you only fastboot flash it or use microsSD method.
Now you still have google splash screen when trying to boot ?
If yes, you still have wrong firmware problem.
Post your fastboot getvar all result without serial & imei no.

As ckpv5 pointed out, firmware and ROM aren't the same thing. Firmware refers to hboot, radio, etc. that is separate from the ROM. Firmware is not installed in TWRP.
Did you convert to GPE using s-off and RUU; or just flashed a GPE based ROM?
Is your bootloader screen black or white?
Also, post the getvar info as directed by ckpv5 above.

I flashed the GPe firmware using fastboot and then flashed the GPe ROM using TWRP. Bootloader screen is black. I will post the getvar data.

As mentioned before you can't install a Sense based ROM on GPE firmware.
If you really want to install a Sense based ROM, you need to convert your device from GPE back to Sense.
This means you need to flash Sense firmware using fastboot, format data to get back the correct Sense partition then only you can install Sense ROM.

Thanks! I got it working

Htc one M9 won't boot to OS, recovery/fastboot working

Hello, i have a big problem with my HTC one m9.
Today i tried to update it to the latest VIPER one rom (5.0) from an old insert coin rom (3.1.2) but to do so i had to update the firmware and the TWRP to the latest versions. I updated the TWRP but i found out that it does not work with android 5.x rom: the only one who works is the 3.0.0 or lower, but the recovery is now fine. The problem is that, after the update of the firmware (that i don't know if i did it right because i just flashed the boot.img that was inside the rom, i should have been s-off probably), the phone keeps going to bootloader mode. Even if i reboot system from recovery, the phone does not power on the system. I tried to flash ICE 4.0.4 and VIPER 4.3.0 but with both of them i got the same result.
I am:
SOFTWARE STATUS: MODIFIED
UNLOCKED
S-ON
If you need other informations please let me know.
Anyway to solve it? Thanks!

same problem bro :/

I'm guessing that something went sideways when you flashed the boot.img - which is probably the conclusion you've reached as well. In your shoes, I'd go straight to flashing an RUU. This would restore your phone to stock and (assuming it's available) bring your firmware up to date too.

error installing roms.... plz help!!!!!

i have problem with my htc one m9
my device does not start the android rom but instead it boots into bootloader directy
i have tried installing viper rom , arhd rom in my device, the rom gets installed succesfully but when i turn on my device ,the device does not boot the rom instead it opens the bootloader ,if i click reboot it reboots and comes back to botloader
the only rom which have worked is arhd v14.0 but i want to install viper m9 or arhd v20.0
my device is rooted , bootloader unlocked,twrp recovery installed
plz help!!!

As explained at several locations here in the One M9 forum (e.g. in the FAQ of the ReadMe thread or in the dedicated threads of the roms you mentioned), your firmware is outdated if a rom doesn't boot although TWRP doesn't state any errors.
If your phone isn't S-OFF you'll need to get back to stock for installing HTC's official OTAs. Be aware that you mustn't update to firmware 4.x if you want to use ARHD since that rom is EOL and based on firmware 3.x.
All information that might be needed for getting back to stock can be found in the ReadMe thread.
