Flash PhilZ recovery after you flash StockCWM-EL26. PhilZ will flash CM11.
Wipe with PhilZ, then flash CM11. Don't bother using PhilZ to backup or restore, it doesn't work.
I'm also still using a D710 running CM11.
I never noticed the ISOREC. I had the kernel download page bookmarked since forever, I just noticed it now points to Old Versions.
What's the benefit to ISOREC? The old CM11 recovery seems to be the best...
Probably because work was started on CM12 before but never completed/corrected, its probably easier to perfect what was already started versus starting from scratch on CM13.
EDIT: unknownsoldierx, believe it or not its easier to step to lollip...
Updated to 20151115. Stagefright detector says all vulns are gone. Yay!
Bad news is something broke compatibility with Xposed.
You prob have APN settings set wrong... If you are using nova or apex launcher, make a shortcut on your desktop to settings-->APN... Should have a boost selection there...
Boost phones use the Sprint variant of this ROM, so yer all good there.....
