That sort of confused me a bit
p) but I'll explain:
Inside the recovery .zip file there are 2 files, another .zip and recovery.img. The recovery.img is the most updated version of recovery (v3.0.0). The other .zip file is the actual update, and inside
that .zip file there is boot.img. You can copy that to your Android folder. Then flash the first .zip update through recovery as normal. Then boot into fastboot and use the command 'fastboot erase boot' then the command 'fastboot flash boot boot.img'. Then everything will be sorted.
If there's anything there you didn't understand, let me know
