I flashed this recovery on kk beta, and I got stuck on HUAWEI Ascend bootlogo (NOT bootanimation) And yes, I flashed recovery, and entered fastboot reboot.
I can reboot, but that leads to the bootlogo again. ADB doesn't recognize it anymore.
EDIT: I was able to boot into TWRP after a few tries, and when I just rebooted system it worked again
-Huawei Ascend P6-U06, running MIUI v5
-Samsung Galaxy Tab 2 7" GT-P3110, running stock 4.2.2 Touchwiz
-Samsung Galaxy Ace s5830i, running Cyanmobile Experience
