Maybe a stupid question, but there's no way to backup TA prior unlocking? If not, does the drmfix work as it should for the XZ2c? Don't wanna render the phone unusable, use the camera pretty much :)

No way to backup. :(

Xperifix works only in OREO at the moment, you need to downgrade your phone with my uploaded firmware.

But after taking one shot with the camera in Oreo, you can upgrade to PIE and still use the camera.
But then, without the drmfix, the noise reduction will be deactivated.
You will get the same camera quality like on AOSP without a GCam port. :)

As I suspected then. Unlocking the bootloader is easy on Xperia devices, keeping drm's (with the downsides of loosing them) are not ? I'll keep it locked until there's a way to back it up or drm-fix work for this device ?

That's okay, but keep in mind, that you can take pictures in PIE with the listed procedure :)

Hi everyone, not sure if this is the right place, but I have a question...
What if I want to use TWRP purely for backup functionality on XZ2 compact? No intention to install any custom roms yet.. no need
Is it possible to simply have TWRP only for backups? I do not even plan to root it.. is something like that possible without breaking something? Like DRM for camera etc?
Thanks.

You need to unlock the phone and break the Sony DRM.
Or you can't flash stuff on the phone

Hello

After unlocking bootloader and flashing twrp (starting from stock 163). Are we still able to receive ota updates from sony?
It seems there is a new(er) 202 version available but if a click ond device's update-check nothing happen.

Is is possible to update via another mechanism or as from now only custon roms?

Hello,

I own a XZ2 Compact (German version) and I want to root it. Is there a way to get root access with the latest build (52.0.A.8.25)???
After hours and hours of reading, trying, flashing etc. I com to the conclusion: This is quite difficult! Maybe anyone can help me with it.

At the moment I unlocked the bootloader and 52.0.A.3.84 is the build nr.

the code
Code:
fastboot flash recovery recovery.img
leads to the following message

Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery twrp-xz2c.img
	target reported max download size of 536870912 bytes
	sending 'recovery' (34140 KB)...
	OKAY [  0.806s]
	writing 'recovery'...
	FAILED (remote: No such partition.)
finished. total time: 0.820s

After some looking/reading I found a thread that there is only one partition in pie, is that right?
So is there a way to have a second (recovery) partition?

Thx for any help!

    There always people complaining, regardless what you do.

    I use only phones where I can get custom rom updates over a long time period.
    I am very happy about my first time with a xperia smartphone and the possibilities.
    For other vendors you are forced to use the stock firmware to create a custom rom.
    Here you can choose between the stock firmware or the SODP AOSP firmware developed from scratch without hacks and focused on stability and free from bloatware.
    Here you have the possibility to help as a volunteer and take part in which direction the SODP AOSP firmware gets developed.

    About the stock DRM, yes, I hate it, too.
    But Sony does move away from it.
    They did weak it with Oreo and further with PIE (more features without DRM allowed get used) and the Xperia 1 is now the beginning of xperia smartphones with camera RAW support on stock, not only SODP AOSP based ROMs.
    So it goes in the right direction and is very promising for the future.
    Maybe on xperias starting with Q/R the DRM will disappear.

    I am very glad to hear they're slowly moving away from it, it would make their 'open' device program much more open :)

    But yes, people will always complain, it is how progress happens, if there's no complaints there's nothing to improve ;) it's not necessarily a bad sign! it means people are using your device!

    I do agree the open device program with its dedicated developers and community input is pretty unique and amazing to have, which is exactly why I've stayed with them for so long, but I simply didn't have a choice this time around, I needed a working phone with my own software on it, and I just couldn't get it working the way I did with all my other phones. It might even be that the phone itself is broken, but I can't exactly make use of the warranty anymore, which also bothers me because OnePlus seems to be willing to replace your device just fine.
    All in all I was very disappointed and angry this time around with the experience I got, and I will stand by my words as long as they continue this behavior. So I do hope they will continue removing their hardware DRM ;)

    Preach, brother. I have been making this very argument for years, starting when HTC on Verizon started making life impossible for those who wanted root access. My attitude has always been, "it's MY damn phone; I want to do with it what I want." Although I don't tend to root every handset anymore (confession, I usually have multiple handsets, and one of them is almost always rooted), your position is precisely mine, and while I fancy the notion of a rooted X2C Compact, there's no way I want to deal with the BS hurdles Sony has thrown up to this supposedly "open" device.
    There are definitely even worse smartphone OEMs to pick than Sony, Apple for instance haha, and perhaps Samsung and HTC and Huawei (who seems to have removed the unlock ability from their website entirely), and I will *never* buy devices from them as long as they think they can own the device AFTER you bought it.
    It's not even that I care about root access, I usually have that disabled entirely for safety reasons, it's just that I don't trust the default software on any device, one of the first things I do when I buy a new computer is wipe it, and Lenovo's Superfish debacle and HP's exploitable system tools/drivers have firmly confirmed to me that this is the right thing to do (plus I run Linux/Arch/etc, couldn't care less about ConsoleOS 10).
    Not to mention I would've never bought the Oneplus if I couldn't do that, because I know exactly how much China loves to put backdoors in things, hell even the USA does that (remember PATRIOT anyone? or what about the whole shadowbrokers dumb with exploits that the NSA kept to themselves for years? Entire reason WannaCry existed!), so while some people may call me paranoid, I think it's my right to be able to change the software on the computers that I buy, whether they fit in my pocket or not :)
    Edit: and of course the fact that your device stops working as soon as the OEM stops supporting it of course, I think it's beyond strange that governments aren't calling a halt to that, the amount of electronics waste is massive, and this kind of scammy 'oh guess your device is useless now and you'll have to buy a new one<3' behavior when opensource roms could easily keep your device running for years after makes me want to run political campaigns.

    That was the official pie rom :p and like I said it worked before! I guess with the amount of ROM switching some other files got lost somewhere.
    As for Omni, it seems like it doesn't like my NFC chip and occasionally seems to crash with opengapps (stock) installed.. I've been trying to get TWRP to work with my own compiled AOSP ROM, but I might just try put Stock on it again to the best of my abilities with your above instructions tonight, if not I'll probably invest in something like a google pixel 3 which also has a snapdragon 845, would be nice to compare the opensource experience with that one :p at least the build instructions seem pretty straightforward https://source.android.com/setup/build/building.html or perhaps a oneplus device or something non-waterproof with a waterproof case.. or a raspi 4 with screen/bat/4g and a bunch of ducttape until it's waterproof :D not like there's anything that's not made of glue these days anyway, except maybe the fairphones :cyclops:

    thanks for those instructions though! I'll try them out tonight. and thanks for not turning your back on me because of my frustrated responses, I know I'm not an easy customer, but you gotta admit the smartphone world is more voodoo than logic with the amount of bugs and workarounds and bugs in workarounds and so forth :p

    you could also just execute my build environment on github to build the stuff :p

    No problem, you're welcome :D
