[Q] How to trick Sony Update service to install an specific version
I updated my phone to a Unbranded KK version while I was waiting for may Sim unlock code to arrive.
It finally arrived but now, when I put a new SIM in it, it doesn't show the window asking for the unlock code.
I tried with many versions from various countries with and without rooting, but it always "pretends" that I don't have any SIM in the phone.
I nearly out of options and I'm not even sure that I don't have a faulty phone
I was thinking in put back the original firmware (1280-7858 1177) for see it makes a difference... but how can I get a hold on it????
I was thinking if there is a way to trick SUS into thinking that I have that version for it to download and install it.
Does any one know for to change the Customization number and the ID of a Z1 Compact???
Or some other way to deal with my problem?
