I unlocked (not rooted) my HTC One XL using official HTC method. Then I install goomanger and installed latest open recovery script TWRP 22.214.171.124 evita. goomanager said that it was installed. Then I tried to boot into recovery from goomanger (there was a note that root access will be acquired and if this doesn't happen I have to go to recovery manually). Nothing happened I was still in goomanager.
From TWRP website -->
You must be S-OFF or have taken HTC's unlock to use a recovery on your device!
So I booted into fastboot and then selected recovery and pressed power button. See the screenshot for what happened. I got the 'briliant' screen then black screen with mobile and green something above it and then black screen with mobile and red triangle. The red one stays there for 2-3 minutes and then mobile restarts into normal mode.
I want to run twrp to install cm10
