Sony recently updated it’s past flagship Xperia Z to Android 4.3 Jelly Bean 10.4.B.0.569 firmware and then soon rolled out some more updates packing up some bug fixes and performance enhancements. With the new update, the build number changed to 10.4.1.B.0.101. The method posted earlier on our site to root Xperia Z on Android 4.3 Jelly Bean may not work with the least build number, so we’ve found a working CWM recovery which will allow you to root or flash any custom ROMs if you wish, not only on this build number, in fact it works on all stock firmwares of Xperia Z and also all variants of Xperia Z.
Before we head towards the custom recovery installation instructions, let’s first have a look at a brief intro of the custom recovery that is CWM [ClockworkMod] 18.104.22.168 in our case as many of you might be the first timers here.
A custom recovery allows you to install custom roms, mods etc. Along with these, you can make a Nandroid backup, this helps you a lot as you can move back to the previous working state of your phone at any time you want if you have backed up your current system. In some cases, to root the phone you need to flash SuperSu.zip file in the custom recovery, having installed the recovery may help you while in some cases to install the recovery easily, you need to have the phone rooted. You can also wipe cache and dalvik cache of your phone using a custom recovery. There is alot more you can do using a custom recovery, you mayinstall one and experience it yourself for further know-how.
