[Q] New Z1 Straight Out Of The Box. Now What?
Just got my brand new Z1 (C6903), SIM and bootloader unlocked (SI 1276-0471.2), and have booted it for the first time. It is running 14.1.G.1.518, shows 1 system OTA system update available to 14.2.A.0.290 and a number of OTA app updates available.
I'd like to root, install custom recovery (preferably dual) and back up the phones original state including TA partition, then move on to updating to a 4.4 Kitkat build, probably stock as I will leave the bootloader locked for the moment.
Despite having worked on (rooted etc.) 2x Xperia SPs, I have read through the many Z1 rooting threads and ultimate guides and I have no idea where to start. Most rooting threads start with downgrading, which I shouldn't need to do, there are usually multiple methods for each firmware version and most don't seem to root the currently installed ROM (especially the newer firmware versions), they require a ftf file (of unknown SI number) flashed over the current ROM. There doesn't seem to be a way to retain a firmware version with the correct SI number for my phone.
I think I read that Bin4ry's rooting method is the best for this firmware. Is that right? The dual recovery seems as though it could be problematic, will it be overwritten when I update or flash an ftf file? Once I root the original .518 firmware etc. what do I do next to get to rooted Kitkat (.757)? Is it possible to get a rooted 4.4 stock ROM with the same SI number? Should I actually be bother with such details?
I could really use some clear advice on the best way to proceed.
