[Sony Xperia Z Ultra] DooMLoRD:
[ info ]

So here is an Advanced Stock kernel with DUAL Recoveries for the Sony Z Ultra Google Play Edition!!

[ note on ZU GPE bootloader ]

so i have done some testing on a users device and here is what i found:

there are signature verification issues if u try and flash a modified OTA zip

even after unlocking bootloader we cant flash custom recovery to internal recovery (FOTAKernel partition)

i have tried:

fastboot flash recovery recovery.img

and

fastboot flash FOTAKernel recovery.img

it flashes correctly but device still goes to standard recovery

then i tried with rooted device and directly DDed onto the FOTAKernel partition, the device never entered that recovery

so i am guessing tht Sony has blocked access to the FOTAKernel partition for flashing custom recoveries

only option remaining... use the old recovery in boot kernel system...
