Is it possible to enter fastboot without a pc? I ask because I had read that if you enter recovery via fastboot its almost like being s-off. I was actually able to flash a kernel that way. Thanks for replying.

Most ROMS will give you the option on the power menu (when you press down power button) to "reboot to bootloader". From there, fastboot is the first option in bootloader. edit: also you could hold down power and vol-down at the same time from powered off state, also AmonRa will give you the option to reboot to bootloader under developer options.

No technique or series of events will ever magically allow an S-ON user to bypass the secure flag and flash a complete kernel, boot.img and all, through recovery. Simply is not possible.

You need to fastboot flash the boot.img which requires a PC.

Rebooting to recovery from the Rom, or entering recovery through bootloader doesn't make a difference.

But to get to bootloader which is what I think you want, turn off the phone then boot by holding power+volume down button.

I think you're talking about flashing a kernel in hboot, which doesn't have anything to do with fastboot. You place the PH98IMG.zip onto your external sd card and boot to hboot, say yes to the update, and if you get a main version is older error message, there's a fixmainversionlow.zip that you can flash to avoid that.

That puts you in hboot. To go into fastboot mode, you select fastboot there on the hboot screen.

Well, he might be talking about HTC Dumlock, but other then that, you're right.
