[Xperia Z Q&A, Help & Troubleshooting] Endoralol:
Hello in this tutorial i would like to explain to people that have no expirience in how to unbrick your sony xperia z device, i'm not expert or something like that, but i wanna share it with you guys. Its tested and it works just fine, tested it on my phone (c6603).

While we wait for lolipop this is great ****, were not loosing anything, once u decide to step to lolipop unroot phone through king root, remove access to your sd card, firmware will change with your next update and thats it, your phone will be again unrooted and ready to work back on lolipop versions, i would like to also have cm12 lolipop, but its impossible since my bootloader is locked (t-mobile) yeah **** thing, but anyways i dont really care about androids not really important if i have jelly bean kitkat or lolipop same ****, i want only more space! So i searched alot, and i found perfect aplication how to place apps to sd, device have to be rooted.

Lets start with how to downgrade or how to unbrick your phone, i heard there is more versions about bricks, but i found this one that can actually repair, now all depends whats broken.

Flashboot: https://userscloud.com/4ecacrck3mvs (Once you install Flashboot, downloaded firmware and firmware that was in (C:\Flashtool\firmwares) to C:\Users\XXX\.flashTool\firmwares

this should not be hard. Once you finished that you are ready to flash open flashboot without phone connected and click power icon or however is it called when u point at it it says (Flash device), then choose Flash Mode and click OK, let first 3 optiions to wipe it, since you will use firmware thats its probably lower than your right now nothing else do not touch, click flash and wait for window to jump usually takes around 1 min for it, it will say to put inside cabel and to click volume down button, it will start proccess it takes around 1-1.5 min, after that disconnect usb and start up phone, congratz your phone is on 4.1.2 android back :)

Download Kingo Root: http://www.kingoapp.com/android-root/download.htm , once u did that install and start up, but before that check usb debbuger and unkown sources, does not require bootloader unlocked, so no worries, next step you should do is start up and click to root, your phone will be automaclly rooted, maybe it will ask you some requests, but not sure now since it sometimes ask me, and sometime not, anyways, your phone will be rooted however, next download and check via application root checker.apk from android market.

If your phone is correctly rooted, i would congratz you on succesfully rooted phone :) and we will continue to new step which is the last one
