Hello,
Since i am new to rooting on a Sony device , i tried it downgrade to lollipop in order to backup the keys all is fine.
I am now back to stock, since i cannot understand some things.
I want only a stock root rom, but i want to keep the drm in place or simulate it in some way i dont wanna lose some funcionality of the phone is that possible?
Since i read things about drm fix etc.
Can someone explain what is possible with Sony and rooting with emulate or replace drm after root.
btw sorry for my bad english.
Just flash patched stock kernel with drm fix and you are good to go. btw check for it in Xperia Z5 Premium forum, not here.

Evening all,
Just placed an order for the Z5 Compact after my Z has started playing up after 3 years of use,
Basically I had mine rooted a long time ago, and I havnt really touched it since or done any rooting/customization in ages and im drawing a blank..
Basically want to root the Z5 and downgrade to the 4.42 firmware as I have on my Z, as I dislike the 5.51 software the menu options etc looks very tacky for stock Sony layout, and it looks like 6 marshmallow is the same.
Is this feasible or reccomended?
Is there a step by step guide I can follow as I am seriously ****e with computers and all this stuff, I also wanted to learn about and if there are guides on how I can customise the menu etc If I can keep 5.51 or even upgrade to 6.0 and root the device and install a custom theme and change the menu layout etc?
Is this possible at all, I know people have custom software but I havnt a clue on how to go about rooting it let alone customising it...
Any help much appreciated!
There is no 4.4.2 firmware available for z5 series...

I don't think you can customize settings menu in stock roms...

Im planning on rooting from 5.51 found a decent guide with use of command prompt so should be easy I hope! Is there an app/program downloadable after root which will allow me to apply custom themes/ menu layouts.
I can only remember Super SU, and theres an aptoide one I had iirc
hey. no offense but i'd suggest you read and learn a bit more about rooting newer xperia devices before you do any mistake.
its for sure no easy thing if you arent much into this stuff. just to mention one thing: at this moment there is no way to root the z5
with locked bootloader. unlocking your bootloader means, that you most probably lose your warranty and the drm keys. those keys
can be simulated by a workaround, but infact they are gone forever without any chance to restore them.
in the end, rooting the z5 now is a process of unlocking bootloader (via flashtool or adb), flash kernel via adb, flash twrp recovery via adb
and finally install supersu via twrp flash.
these should be enough keywords to google for, and/or getting knowledge here in xda forums. once again, i just can advice
you read all those guides twice....

DRM keys arent really required though are they? are they not restorable/ way to back them up prior, ive googled Z5 compact root and ive got loads of links on search results though
Voiding warranty of new device and god knows what will be with restored fake DRM keys with further updates, and no, there is NO rooting Z5 series with having Bootloader locked for now, i doubt there will ever be a method but hope im wrong. You might want to reconsider Z5 series, replace your Z with Z3 that is easily rootable even with locked BL and is on Marshmallow list.

well, the drm keys are required for e.g. x-reality, camera postprocessing, ps controller support and much more. at the moment the drm restore patch works, but who knows, google or sony could counterpatch this aswell. you can only backup them with root. to get root you need to unlock your bootloader first. unlock bootloader = drm key lost forever. you cant lock your bootloader without original drm keys, and with unlocked bootloader you dont have ota updates and pc companion wont work anymore. means, you always have to update manually with
flashtool.
Really?! Cause with my Z I could link up with pc companion and do a factory reset which wiped out the root and everything on it when it froze up..
What about the main thread on this forum... is there any other reading or threads/guides in relation to this
Hi,
I have been using Xperia z5 for long time have unlocked bootloader (lost DRMs) rooted and installed custom roms.
Now, i want to give this phone to my cousin who loves stock rom only and prefer to get OTA only. I want your help in stimulating the drm (using the famous patch), install stock latest, relock and Unroot.
Please advise me about the steps that i need to follow as i am feeling bit confused.
Thank in advance
You can't simulate the missing drm keys with locked bootloader. Sorry.
Ok sorry for idiotic question, but what are DRM and why do i need them? i backed them up on start before rooting, now i have tested few roms and stuff. But do i need to restore DRM for better photos or something? Or os not possible to restore DRM on costum rom. Its my first sony in years
I don't know that much on DRM and Development, I'm just a passionate guy, so what am gonna say is perhaps wrong so dont blame me
DRM (Digital Right Management) are keys used to "protect" the phone.
Those keys are sets by the firm (In this case SONY)
To enable some functions on the phone.
When you buy a new phone, DRM are already set up and everything works fine, but some phone functions require those keys to work (on the Z5 x-realty photos, bravia engine display needs them to work) .
If you unlock your bootloader, you delete by the same time those key located on the TA partition and so, X reality and Bravia cease to work,
I know that on the Samsung devices the fingerprint sensor is completely disabled if you lost DRM I don't know if it's the same on the Z5.
Once deleted you can't recover them, they're lost for ever, even if you relock your bootloader !
Actually I don't know if you can recover the keys if you have backed up your TA partition, but according to what I've read you can't, BUT you can emulate them.
DRM aren't only for phone, you can find some in video games protections, computer, or that kind of stuff
So is missing bravia noticable on phone?
Actually I can't answer, I'm waiting for a locked bootloader root in order to keep the originals DRM.
Guess you should ask someone who has unlocked his bootloader and lost DRM to see if there are some noticeable changes?
I don't see a big difference regarding X-Reality, but where there's a big difference is in the photos taken without the DRM keys.
If you want to root your phone and keep the DRM keys, read this: http://twigstechtips.blogspot.ch/2016/04/sony-z5-compact-root-without-losing-ta.html?m=1
I'm currently trying to get the TA partition restored on a stock non-rooted ROM
Ivory flaw is only available on lollipop?
I'm f*cked then I'm running Marshmallow and I don't want to flash a new Rom wiping everything :crying:
Thanks but I'll try later if there no root for Locked BL on Marshmallow

Hi. As i readed to back up drm we should downgrad to MM but to downgrad to MM you should unlock first. So you will loose drm befor downgrading??.
Also it seems that after loosing drm camera and other sony related features will not work any more.

You can downgrade to MM without unlocking bootloader, but you need a MM FTF. On Xperifirm, there are 3 Firmwares like Commercial, Service Exchange etc. based on MM, i didn't test it but you should back up DRM keys on it.
Unlock for Downgrade? Total BS.
This is one of the good Sides of Sony - You can use any Offical FW you want.
As stated above in XperiFirm are on any Phone I know 3 Versions for Service Exchange, Press Demo and Retail. They are for XZ still MM - No need for any Unlock and then run the usual Back-Up-Unlock process.
That Simple.
