i followed the instructions on the CyanogenMod wiki (http://wiki.cyanogenmod.org/w/Install_CM_for_jewel) to install CM 10.2 on my EVO 4G LTE.

i am able to launch TWRP 2.7.0.8 and receive a notice that CM 10.2 flashes successfully but when i try to reboot into the system, i see the white htc screen, the screen goes black and the whole thing just repeats itself until the battery dies or i get back into recovery and shut down.

there is a note at the bottom that says " if unlocked with HTCDev Unlock, must have its kernel flashed via fastboot." since i used the instructions on that page, i assumed this didn't apply to me, otherwise it would have been included within the instructions.

i have installed CM on my old captivate and my Nexus 7 successfully, so i have done this before by following instructions, but am at a loss as to what happened this time. any tips would be greatly appreciated!

If you're S-on you have to flash the kernel separately from the ROM. Hit the top link in my sig and scroll down to the section on S-on kernel flashing for more info.

thanks for your quick reply. can i use TWRP to flash the kernel? i can copy the boot.img to my external sd card and then flash from there. i am unable to push files using adb.(not sure where the problem is. i installed sync but do not have media player 11 installed so maybe that's the problem)

No, you can't use TWRP, at least not for flashing in recovery. You do have a few options, though. You can use the paid app Flash Image GUI from the Play Store, use the TWRP Dumlock feature (link can be found in my guide), or get S-off (your best bet). There is a link in my guide on how to set up ADB on your computer, so maybe that will get you headed in the right direction.
