Unlike Xperia Z1 and Z1 Compact there are not enough custom roms available for Xperia Z1s. We don’t know why deveopers are not making any good custom roms for Z1s even though it is more good in specs than Z1. However in this post we are sharing Stock ROM / Firmware for Sony Xperia Z1s C6919. We will update the article if we found any custom roms for this phone.
Flashing firmware’s or custom rom’s to sony devices is as easy as updating your device to latest version of android. Also it’s pretty easy to flash rom’s to sony phones compared to other devices. All you need is your phone’s firmware file (.FTF file) and the popular FlashTool. From here you can download the latest firmware for your Sony Xperia Z1s.
If you want to try other custom rom‘s in your device you can download the available roms or recoveries for your Sony Xperia Z1s and flash it using guides provided in this website. Inorder to install any roms other than stock you have to root your phone and then need to flash custom recoveries like CWM (clock work mode) or TWRP on your phone. Usually we flash stock rom’s if something wrong with the software side. So, after firmware flash your Sony Xperia Z1s phone will be in a factory reset condition.
