Read here : Flash K800 CID53 with K810 software CID53 (for begginers) - Top Sony Forums cos your phone CID is 53 and use these files as you should first debrand it and it's a good thing;
MAIN : K770_R8BA024_MAIN_GENERIC_VI_RED52
FS : K770_R8BA024_FS_CENT_EUROPE_RED52
custpack : HB1-06_Gen_CDA102568_207_R2A_GENERIC_CENT_EUROPE
and for unlocking read here : Patching CID53 (DB2020)DB2010,2012 - Top Sony Forums and to download the Simox SIM-lock gerator attached below to make the unlock patch

Just thought i should mention, I followed this advice yesterday and it worked with a few tweaks.

-> In the first tutorial, there is a screenshot missing, do exactly the same thing you did with the MAIN file but using the FS file.

-> in the first tutorial, do not follow the last step ( flashing the lightsettings )

->in the second tutorial, i found that the executor only supported R8BE001. So i had to flash it using K770_R8BE001_MAIN_GENERIC_VI_RED53.mbn. Then once i applied the QA patch to this i flashed the main of R8BA024 , then applied QA , simunlock (still in the same session ) and the flashed the FS and custom.

note: if you fail to apply the quick access patch directly after flashing the main (without disconnecting) you have to start over and flash back to R8BE001

ALWAYS run BOTH the main and FS files through babeck and ONLY use it if it passes.
The ones that did not pass babeck i just googled the filename to find an alternative download

sure can..by using SE tool box...u can downgrade ur CID....4 diamonic prob...it think u should use SEUS software to enable ur phone using Jad Manager...interupt the flashing sequence of updating the firmware of phone n u get an empty phone so that the jad mananger can detect it without prob.....
