Drm Keys ? Unlocked bootloader ? MIUI ? - Xperia Z3 Q&A, Help & Troubleshooting

Hello everyone , I have a Xperia Z3 D6603 and I hesitate to unlock the bootloader .
I currently run on official 5.0.2 rom but multitasking problems annoying me and I would like to test some custom rom (which one btw ?) especially MIUI V6.
First, is MIUI available for Z3 ? I found it for the Z2 but anywhere for Z3 ...
Secondly and most importantly I hesitate to unlock the bootloader because of the problems of DRM keys obviously. What I understood, I would have to make a backup of my TA partition before unlocking the bootloader and if I want to put it "completely stock" (example : for resale it) I need only reflash the TA partition, right ? So during the time when i'm on custom rom I lose all the benefits such as quality of the camera, the treatment of screen (what else ?) etc ?
So i can't have the benefits of drm keys on a custom rom ?
Thx for answers !

Hi guys, just a silly question :)

Hi Guys, can anyone point in me in the right direction? I currently have :
Sony Xperia Z5
Model number: E6653
Android Version: 6.0.1
Build number 32.2A.0.305
Unlocked bootloader.
How would I go about rooting this device? Th Reason why I'm asking is because all the guides I find are for 6.0.0.
Regards,
Robert

Hi, Do i need to downgrade to 6.0.0?
To root and keep all the funtionality intact, yes you need to downgrade and not to 6.0.0 version but to LP firmware .200 or .152 anyone will work.

He said he had an unlocked bootloader meaning he already has his TA keys backed up or they're lost forever. Either way can't he just flash custom recovery and then flash SuperSU zip. That should only take about 5 minutes.

Lollipopo vs. Nougat bootloader

Hi All,
I'm on Lollipop bootloader. I remember that I haven't got any answer from Xiaomi to unlock the bootloader but I could install cm 13 somehow dirty way.
If there any method to make the same with Nougat bootloader because I have made a try again but SMS didn't arrived ?
What is the advantages of the Nougat bootloader? Can I use Nougat blobs with the old bootloader?
best regards, gcsuri

Sometimes SMS does not arrive. You have to verify directly within the app.
Also, permission is transmissible meaning you can burrow an account that already has unlocking permissions.
You can't install a ROM that uses Nougat bootloader, like RR 5.8.3, if you have lollipop bootloader. That's all.

Thanks, that worked well; It required an old version of miflash:

And an additional step to enable oem edl

Questions from new owner

Hello,
I will get Xperia XZ tommorow so i've got some questions.
Probably i will unlock a bootloader and install some custom rom. Which one rom is most worth installing? And how is camera quality after bootloader unlock on custom rom? Is it worth to unlock it, root and install custom anyway?
Thanks!

Did not notice camera loss of quality.
Yes unlock and root, this phone is great but stock battery is not good. With some tweak you'll regain that.

root, recovery, and kernel.

Hi everybody.
I just had the xz F8331. i had the xz premium stone with root and recovery, but my xzP is dead. so I buy the xz. for now I have not done anything with it yet. I will unlock the bl, root, and installed the twrp. if a person has everything they need to perform the procedures it would help me a lot. I do not want to make a mistake. so if someone could help me a little it would be cool. I am with the firmware 192. could you advise me for a high-performance rom on this xperia xz please. I have not yet unlocked the bl so I wonder if there is a fix drm? Thanks in advance for your help. I already read a lot on the forums but I do not understand everything because I am French and not very good in English.
