Error 155 is usually a firmware or HTC signigature issue.. just flash the old lp firmware and run the ruu. Gotta downgrade firmware before the ruu will match the signatures.

any guide or reference for that?

Is it possible for s-on devices?

Not possible on S-On, only on S-Off
And to OP ... make sure you don't flash a GSM firmware on your Sprint device, it may brick the radio or totally brick it.

I am planning to use this RUU for downgrading to Lollipop:
lollypop:
RUU_M8_WHL_L50_SENSE60_SPCS_MR_Sprint_WWE_4.25.651 .14_Radio_1.09.20.0209_NV_SPCS_1.52_003_release_42 6232_signed_2
http://www.droidviews.com/restore-sprint-htc-one-m8-to-stock-rom-with-ruu/

I have flashed this firmware:
https://www.androidfilehost.com/?fid=23991606952612412
Now trying to flash lollipop, hope it will work!

It worked.. thanks for the help.

Can someone explain step by step of downgrading please.I have Sprin HTC One 8 . I hate marshmallow , my phone battery is drained after couple hours, it's warming up, I lost my contacts, contacts don't want to sync from FB etc. How I can downgrade back to previous software. Thank you.

I want to down grade because the phone is horribly slow since upgrading to 6.

Cool. So what is the question?
There is some info on the thread about how to downgrade. But to be any more specific, you need to give some info about your phone (fastboot getvar all, and post the results - delete your IMEI and serial number before posting).

Frustrating
This is very frustrating, I can not downgrade due to the firmware issue. Where can I get an older firmware for
a developer phone, s-off and bs_us001?
tpteam6, how did you find yours? I search, but found nothing. Some twrp nand backup stuff.

couple things. this is the verizon HTC one forum. since you are s on you will need an encrypted ruu to recover that phone or unlock the boot loader via HTC dev assuming this isn't a Verizon phone. you can then flash a custom recovery and flash a custom ROM.

How can i get S-OFF on my HTC M7 with no OS?
if s-on, relock bootloader to flash RUU
Sorry for that, I assumed the procedure would be same as HTC one x. Where I achieved OS by relocking and them flashing ruu.
Dunno what would be good for you. Try searching around...

Quite sure you can, just find the VZW 4.4.3 firmware and flash it then flash a 4.4.3 ROM. Or if there is a 4.4.3 RUU you could do that as it'll flash everything including firmware, ROM, etc.
You need to be S-OFF to flash firmware or do an RUU though.

I'm not S-OFF, is there any way to do it, or do I just have to wait until I can get S-OFF on 4.4.4?

If you took the official 4.4.4 update you will have to wait for S-off , m sure Sunshine devs will create an exploit

Its not clear what you or the OP are asking exactly. If the intent is to "downgrade" to run firewater, then NO you can't do it.
If already s-off, just flash the desired firmware by fastboot and restore a stock nandroid.

Not looking to run firewater. Just want to go back to 4.4.3. Running the stock rom, got the OTA 4.4.4 last week and don't like it.

This kinda sucks. Broke my original M8 and the replacement came with 4.4.4 on it so I'm stuck with a stock HTC phone. I want my GPE 5.0 ROM back! Stupid Verizon.

[Q] updating to lollipop with s-on help needed please

HI
first thanks for taking the time to help me i really appreciate it
i have an htc m8 ,m8_ul, , s-on ,unlocked bootloader, cid htc_621 , hboot 3.19 , radio 1.22
device currenly bricked but can access booloader and recovery (used to have a 5.0 rom)
i want to upgrade to latest lollipop version can i do that with s-on?
how can i do it?
thanks in advance guys
help much appreciated
by latest lollipop i would assume sense6 and not cm12.
I have installed cm12 on my m8 for a few month now. Getting the latest ATT update has been a pain so far as I cannot downgrade to kitkat.
if you are on a kitkat version then go to setting -> about -> check for updates and you are good to go. just make sure to use wifi.
yes i want sense 6
So i will restore the stock backup
flash stock recovery
Relock bootloader then get ota?
But with my cid will i get the latest updates?
anyone?

Mostly correct, but you don't need to relock the bootloader (nor do I recommend you do so).
You'll get the latest OTA for your CID. I am not clear what you mean by "latest updates". If you intend is to be on the stock ROM for your CID, you don't want a more recent update for another carrier.

Edit: those links for getting ur device in stock state not flashing MM firmware but i found it useful to share
The linked instructions are obsolete since the backups they were made for do not exist anymore. The updated instructions and the revised backups can be found in my google sheet (a link is in my signature).
But be informed that there is no official MM update for other versions of the M9 than the developer and the unlocked US version. If you want MM on any of the other models you need either S-OFF, sneakyghosts firmware package and the latest Viper rom or S-OFF and all files found in clsA's instructions for converting your M9 to a developer edition.
the Only way to back is flash RUU.and the cid must same and RUU's version must equal or higher than your M9 have

The bootloader only gets locked if you relock it with fastboot. (And because many people here seem to be missinformed: There is no need to relock if you want to install OTAs or flash a RUU.zip. The only things that don't work with S-ON and an unlocked bootloader are using a RUU.exe and flashing official firmware packs with fastboot.)

Help with Restoring Stock Android on HTC 10 CID: HTC__060 RUU 3.18.400.2

Hi guys, I need help in restoring my HTC 10 to stock android and the problem is I can't seem to find any RUUs or TWRP backups for my OS version. I was stupid enough NOT to do a TWRP backup myself.
I'm currently on PureFusion OS Android 8.0 but the homebutton/fingerprint doesn't work. I checked their forums and it says i have to downgrade back to Stock Android 7.0 then flash PureFusion 8.0 again. Problem is, I'm stuck at the downgrade part!
Link: forum.purefusionos[.com]/threads/purefusion-on-htc-no-sim-detected.10/
I have the exact same problem with the OP on the post, but I solved my sim issue by restoring a stock recovery.
Anyone can help me find a suitable RUU or TWRP backup for OS ver 3.18.400.2 and CID HTC__060?
Much appreciated.

Sorry but no. Not sure why sunshine won't work.
Purefusion is probably to modified. Try maximus rom, it's as close to a stock sense rom you can get. S-off with that rom as driver and sunshine will likely work
