Does the old trick of booting to recovery via fastboot still work? I haven't had an HTC phone for a while....

Yes you can flash any ROM while S-On. S-Off is not needed for that.
And yes, you can get to recovery via your bootloader. But once you have a custom ROM, the option to boot to recovery will be available when you long press power.
S-OFF only really comes handy as you can flash different FW packages that aren't signed by HTC, or downgrade to an older FW package if required/wanted
Correct me if I am wrong, but from what I understand you can't flash a kernel with S-ON right?

So from what I see you are able to flash a sense ROM with s on and a unlocked boot loader. Can I do this with my droid incredible? Its rooted with cwm and a unlocked boot loader. If so can I use a sense 4.0 ROM? Also I think I have to flash boot.IMG from fast boot right?

If you have cwm installed you can flash any rom made for the incredible.
No you do not need to flash anything from hboot except cwm, which you say you already have.

No it will not hurt anything, you only need root/custom recovery to flash a rom. However i would suggest you think about going s-off, as it can come in handy if something goes wrong. It also allows you to flash recoveries, radios, splash screens, ..., thru hboot.
So then what's the point of s-on?

S-on (Security On) is just a way for htc to lock down the bootloader to stop you from flashing unsigned images and messing up your phone. Along the way enough htc customers expressed the desire to be able to put custom roms on their phones that htc listened and came up with the unlockable bootloader. Unlocking the bootloader however does not turn all bootloader security off, but meerly allows you to flash unsigned recovery and boot images. All other images are still locked and can only be flashed with a signed image from htc. So they let you flash a custom recovery, which in turn allows you to flash roms and kernels. But they still keep important things like the bootloader it self, the misc partition, etc locked so you cant brick your phone. At least not as easily.
So what I'm going to do is make a nand backup then factory reset from cwm then flash a ROM and I shouldn't brick my phone? I thought of the because my HTC inspire 4g(or the HTC desire HD) had a unlocked boot loader and cwm and was able to flash ROMs but I had to fast boot flash the ROMs boot.IMG do you know why I don't have to do it with this phone?

In a nutshell, S-OFF means that the NAND portion of the device is unlocked and can be written to. The default setting for HTC’s devices is S-ON, which means that neither can you access certain areas of the system nor can you guarantee a permanent root. Furthermore, signature check for firmware images is also ensured by the S-ON flag.

Quoted from here
If you are bootloader unlocked instead of S-Off, you also need to fastboot flash a boot.img after each time you flash a ROM from recovery.

If your bootloader is S-On unlocked, you need to flash the boot.img from fastboot each time you flash a ROM.

I have to get 100% stock for warrenty.. my devices is s-off, custom recovery, bootloader unlocked and custom rom. Will i get to stock with these steps: ?
- flash the stock rom (from my nadroid backup)
- flash the stock recovery
- set the bootloader to "locked"
- go back s-on
do i need an unlocked bootloader to get s-on ("writesecureflag 3) ?
Thanks!
If you used htcdev to unlock the boot loader, this can be a problem since HTC can see it!

If you're already on stock Sense 6 before doing these steps, I would think flashing stock recovery is enough. Then you can manually boot into the OS and do a factory reset from within the settings, before sending it off for warranty repairs.

I have an international stock HTC One M9. CID is: HTC__621 and firmware version: 210.709.1 - I've already found the stock recovery for 210.709.1 - I'm looking to install a custom ROM, but I may want to go back to stock later on. I found a TWRP stock backup for 210.709.1, but because I am S-ON, will I not have to manually flash the boot.img? I used winrar to look into the TWRP backup, and I could not find a boot.img. So, my question is: if I flash the TWRP backup using TWRP, will the boot.img automatically get flashed?
You will have to flash the boot.img manually. The boot image is there it should be called boot.emmc.win .

Some weeks ago I was told that all newer phones than the HTC One M7 are able to flash boot images with TWRP even if they are S-ON. (I wasn't able to verify that since my phone is S-OFF.) So there should be no need to rename and manually flash the boot image if it's already inside the backup.

My M9 is completely stock, right now. I'm intending to: unlock the bootloader, flash TWRP recovery, and finally, install an ASOP ROM.
When attempting to go back to stock, I'm going to: boot into TWRP, wipe everything except for SD card, flash the 2.10.709.1 TWRP stock backup, boot into fastboot and flash the command: "fastboot flash boot boot_2.10.709.1.img", flash the stock 2.10.709.1 recovery, and finally, relock the bootloader. Will all these steps be correct for an attempt to go back to stock?

If you use the backup from my signature you only need to follow the instructions on the first page of my google sheet to get back to stock.
Be warned: Since Android 5.1 you should only relock the bootloader if you are completely sure that your phone is able to boot to system and that you ticked the new option that allows a bootloader unlock (can be found in the developers options). Many users already got stuck with a non-booting phone that cannot be re-unlocked because they didn't fulfill these requirements. (Sidenote: If you only want to get back to stock to install new OTAs you don't need to relock your bootloader.)
Besides I read that some people stated that the AOSP roms of the M9 messed up their LTE reception (so that LTE was even unusable on other custom roms or stock rom). I don't know whether this problem is already fixed. Some weeks passed since I read about that problem so I suggest you to read the corresponding threads before you start flashing.

There is no need to flash the boot.img separately on this phone.
As noted DO NOT RELOCK unless you have ticked that "allow oem unlocking" option first. I cannot stress this enough.
Also, no AOSP rom currently has a working camera.

It depends. If you have a current RUU for your phone (i.e., you don't need to downgrade), you can run it S-on, as that's what it's for.
But if you need to downgrade because the only RUU is an earlier version, yes you do need s-off.
S-off also allows you to go back to LOCKED instead of RELOCKED.

Because if you follow these guides your phone will state "locked" instead of "relocked" at the end. And that is only possible with S-OFF. Besides with S-ON you can only use RUUs with the same firmware version as your phone (or newer RUUs)*.
*Actually downgrades seem to be possible, too, but as far as I know only if the two first numbers of the firmware versions before and after the downgrade are the same. Like from 1.32.xxx.15 to 1.32.xxx.8 but not from 1.40 versions to 1.32 versions or from 2.xx versions to lower versions.
