Have managed to compile and sort out some auto build scripts (work to do).
Need to get hold of some TWRP flash-able binaries. Current device state is bootloader locked and unrooted. Waiting for return period to expire........... Hoping current rooted users here can answer a few questions and provide any info so I can progress until I have rooted and personally flashed the kernel.
There are no promises or guarantees here.
EDIT: waited a week, now applied for bootloader unlock code, unfortunately I have to wait 14 days after creating Huawei ID............ stupid !! I don't wish to unlock via any other method.
Might lose interest in that time .......... and work probably get in the way.
Don't really wish to move on blindly if it does not flash, nor stable as stock build. I need to flash on my own device first. In the mean time, I'll get my auto build scripts in order and do a little research. Was hoping to unlock and pull running STOCK official 307 boot.img from device. Downloaded the official firmware package from Huawei, but couldn't find any boot.img ......
