Why reflashing recovery?
The 4ext 10.0.06 rc3 still works.
cm11 4.4.4 is installed and working, also backups and recover backup works fine.
The only thing is that any other 4.4.x rom hang after install @splash
screen - but why?
3.4.x kernel couldn't be the problem because i checked it with a sultan 3.0.x kernel after flashing rom
Had same problems on my Nexus7 (2012 Tilapia) there i had to flash first a 4.4 RUU then recovery again
After that i was able to flash AICP Rom
