How to get root on 257 now that 290 is out?

xd4d3v · Jan 24, 2014

Just received my repaired phone after an attempt to root 290 left it completely dead and not responsive to anything.
Very scary stuff, and I'm glad I didnt unlock the bootloader and the phone was still on warranty.

I'm interested in getting 257 rooted, so I flashed an unbranded FTF of 534 (excluded baseband) and rooted with kingo root.
I was thinking in doing and OTA to 257 but it only shows 290.

What can I do without unlocking the bootloader that is SAFE?

Same question here...

I don't like 290 and I just want stock rooted 257 without unlocking bootloader

I made a guide in the past on how to get root on .257. Here it is:

Odd, my BT Audio works fine in 290 - what's the problem?

I'd really like to stay away from using custom recoveries for the moment.
I've rooted and installed custom roms on multiple phones over the years, and I get the feeling that there are still many unknowns with the xperia Z1.
Users seem to be reporting random bricks on processes that should not produce a brick (I think there's a thread covering that)

Thats the main reason i'd like to get 257 rooted, as it was easy to install with no custom recovery and no unlocking of the bootloader.

I use a mw100 Bluetooth headset and with 4.2.2 all was fine nice sound quality with 4.3 it's sound like 64kbits distortion on high frequency and crackles. Yesterday I testet 4.4.2 slimKat Rom and the sound was fine again but there are other problems and the camera iss slow so I switched back to 4.3 : /
