big warning !
current setool2 version will kill c690x xperia z1 phone when flashing with latest android update : firmware version 14.2.A.0.290
Sony did some changes into latest firmware ( 14.2.A.0.290 ) - it requires new boot update and i'm not implemented it yet it setool2.
After flashing 14.2.A.0.290 firmware into phone without updated boot, we receive brick, i'm trying now to find some way to connect phone, but till now no success.
i'll remove 14.2.A.0.290 from support area until boot update will be implemented in setool2.
But After that Boot update has been implemented

notice regarding 14.2.A.0.290 firmware.
boot update is implemented in current setool2 version and it is uploaded on support area on 11.01.2014
boot update was tested by few guys, who experienced problems with xperia z1 phones after flashing ( null imei ) and their problem was fixed.
but i'm not yet tested flashing of dread 14.2.A.0.290 firmware,though it should be okay now, as the only problem was missing boot update procedure.
i'll wait for my c690x phone and will test this firmware personally.
in any way, i'm strongly advice to anyone redownload current setool2 version from support area,if setool2g.exe size NOT 3841536 bytes, at least to prevent fixed problem with null imei after flashing with xperia z1//xperia z ultra.
And if any brave soul ( or maybe very big phone distributor/seller ) will attempt to use 14.2.A.0.290 firmware with this fixup... well, it will be just great
So the firmware is still not tested but it is expected to be working with the above executable. If you like, you can try it.
