[Xperia Z2 General] kamalmawa:
Sorry mate, I'm not trying to pick on you anything but I have to disagree..

Yes you are right you may not need the DRM keys but most of us love to keep them just in case, for an example even though I knew X-reality worked without the DRM keys I didn't root/unlock bootlader on my Z2 till root exploit was found few months ago..

Yes your goal was clear.. but to create a fully pre rooted package using PRF-Creater only took me less than 2 min (I have a fast PC) and then all i had to do is flash it in recovery that's all.. but with this method Flash FTF then unlock bootalder then again flash custom kerenel etc and with all those steps to flash those hacks to regain the X-reality and bionz engine took me more time than that, yet I'm not 100% sure bionz engine that helps to produce better low light condition photos work properly. Go to that thread you will see people still complaining. Last time I tried this method on my Z it also wiped my data including internal storage when I unlock the bootloader. So it's more time waste.

Yes once again the warranty is meaningless to you, but you need to understand that not every country has the same consumer laws as yours. I live in Australia and none of the manufactures covers physical damages under warranty. Trust me I already tried and I had to pay $125 insurance excess fee. Then I cancelled my insurance as there's no point paying extra $10 month just to pay another excess fee... My broken Z2 http://xdaforums.com/showpost.php?p=53096520&postcount=6 . Sony bootloader unlock page clrearly says unlocking boot-loader voids your warranty. So I would like to have my bootloader locked and DRM keys intact if I ever had to send it to Sony for repair. Otherwise they will charge me for any repair costs.

"Making it easier to try new updates from SONY is meaningful to me and unlocked bootloader makes that possible. " ? ???? well you don't have to unlock your bootlader to flash FTF and try new updates from Sony.. anyone can flash the latest firmware using flashtool and download any firmware from XDA or XperiFirm.

Yes I see you have rooted many device before.. So am I. I had Samsung & HTC devices before I moved to Sony. With Samsung you don't even had to unlock bootloader to root. But if you did some research with those devices you will see that only Sony uses DRM keys to protect their secrets and only Sony devices loose some functionality when you unlock the bootloader. We are lucky devs manage to find a root exploit for Z2 so we could backup our DRM keys. Unfortunately Z3 users aren't that lucky ;)

Problem 90% of us been telling you that your thread made it looks ok to unlock your bootlader without backing up your TA when there's a method to do it.. So please add a method to backup your TA as the first step so your post will be perfect. Otherwise only difference between your thread and DoomLORds advance stock kernel thread is that you are pointing out to those two mods to regain the X-reality, bionz and flashing stock kernel.

No we are not trolling. XDA is not place for trolls we all here to learn from each other.. I joined XDA when I didn't know how to unroot and reflash the stock kernel/recovery for my S1. Luckily it was easy to return to stock with my S1. But if I join today and come here to find a way to root my Z2, your thread would have made me to ignore about DRM keys and later to regret my decision about not backing them up.

Have a good day
