Hi folks
I have an Xperia Z2 and I am considering flashing it with a previous version of Android. At present it is running Lollipop. The original version for the Z2 was Kit-Kat afaik.
Is it safe to flash another version like Ice-Cream Sandwich ?
Well if it would be Xperia Z not xperia Z2 it would be safe :]
But you know, its Xperia Z forum, we had older version of Android, dunno if Z2 have ICS system that you can flash :]
Thank you Akinaro. :good:
You answered your own question already. Z2 was first released with KitKat 4.4.2 (I looked it up) so you can't downgrade to firmware that doesn't exist. Unless some crazy developer compiled custom old version of AOSP, but I highly doubt it!

Hello,
I had the impression of plenty of people unlocking their BL, like far more than 90%.
Now, as I thought about it, it came to my mind that I could be totally wrong about that.
Till now I thought, to unlock BL is like the normal thing to do, and maybe to relock if DRM was needed or DRM hack did not work.
Or, as in case with the latest DRM_Hack from Team HSxEXR, which is really cool! - if you forget to apply it after flashing, you maybe don't want to wipe data/factory reset after you already installed your apps.
So there are some cases where you just want to relock this thing.
But there are maybe some people who never unlocked it and went stock-based all the time? No custom kernels, no multiboot?
Since there is xposed, you can have a lot of things with any rom, if you can root and install a recovery. And there are the fantastic stock based ROMs which I prefered also a lot of the time, because of the better camera.
What is/ was your choice? Feel free to explain I am really eager to know how many of you never unlocked for example! Did you encounter any problems or could you use all the tweaks you wanted to install?
Unlocked 10 minutes after i arrived home with my Z2 XD
I haven't unlocked it and I don't want it because I'm totally satisfied with my stock based rom.
I don't even use xposed.
On previous phones I did both but I haven't crossed anything that would make me want to do it on my Z2
I haven't unlocked my bootloader. I just found the stock experience satisfying and trusted that Sony would still upgrade the software, which they seem to be doing. I use the #nochromo ad-blocking chrome browser and dolphin with an ad-blocker plug-in, so apart from YouTube ads I'm not bothered for root. Emulators run fast, battery life is good, camera is great (if you mess about with manual settings) and benchmarking to 49000 on antutu for what it's worth. Also I have a sony tablet & sony 4k android TV so I've left them all stock so they talk to each other fluidly. MM is only weeks away so I'm not even going to bother flashing the beta rom. And for the record I flashed both my HTC One X and HTC Desire multiple times, to account for the shortcomings in those devices. The shortcomings in the Z2 are so niggly and small that I don't see the point, in fact I have gone sim-only with my provider and refused an S7 Edge upgrade cos I like the Z2 so much!
:silly:
Kept a locked bootloader, only needed to have root.
Well,as for me,im too afraid to unlock the bootloader or even root.First,because im a heavy noob,i dont understand nothing ,even when you explain me,i will be like a girl which says "Ehmm,okay......".
The only thing i did is flashed my phone,thats the simpliest thing ever.My phone is still under warranty so i dont want to mess with stuff like that.
Unlocked it, the first day i got it.
Androplus kernel is must to get the full potential of the snapdragon.
I have LB, but sometimes I unlock for trying ROMs, I have a backup of my TA partition so I don't worry to unlock bootloader every time I want to try something

I did unlock my bl.
But I couldn't really notice a whole lot of difference, even with a custom kernel, so I relocked it by restoring my ta backup(make sure to take a ta backup no matter what). That was half a year ago though.
I might unlock it now that drm restoration is really easy, but I think that unlocking your bl does wipe your phone, and I am too bored to backup everything.
In all honesty, I don't think you are missing a whole lot by not having a custom kernel or a rom such as cm, as sony's software is already light enough.
However, I am guessing that there should be some gains via installing a custom kernel (overclock, or better battery life) so keep that in mind too.
Unlock and relocked several times already... No problems so far. Total freedom of choice....
Until the Xperia Z3, we still have the choice to keep bootloader locked since root exploit have been found.
But with Z4 then later Xperias you are forced to unlock your bootloader to root.
There won't be anymore root exploit for locked bootloader. We are lucky that Sony is allowing the unlocking of bootloader.

Could you explain why?
Isn't it possible that new root exploits are developed in the future?
A root exploit is basically an unpatched security issue.
No system will ever be secure, there are possibly even root-exploits out there which are not shared with anybody
(Zero-day-exploit).
Anyways, I like the way Sony is opening their boot loader for public... It's like nexus.
Unlock after back my TA up, for safety

Nobody with requested skills care of Xperia devices anymore.

Unlocked the bootloader was the first thing I did, after testing the Z2 for a few hours only to see that everything works.
I didn't even bother to take a backup of those DRM keys. Never goig to use anything DRM related anyway.
I needed to flash a minimalistic ROM without bloatwares.
I've unlocked it a few times, but the worse photo quality always brought me back to stock. It's a shame we can't have the best of both worlds

XDA did a very nice article about this a while ago:
http://www.xda-developers.com/a-look-at-marshmallow-root-verity-complications/
This line should be easy to understand: "In lieu of an unofficial bootloader unlock (those are fairly rare these days, short of leaked engineering bootloaders for a few Samsung devices), it seems highly unlikely that you’ll be getting root on Android 6.0 without some divine intervention – the combination of dm-verity (to stop your phone from booting with any modifications to the system partition), and the requirement for SELinux changes in the ramdisk (to let root work), look set to make things rather un-fun for root-aspiring users of these locked-down devices."
I'm so glad sony didn't enable dm-verity on the z2 mm beta or else root would be a HUGE problem for users with unlockable bootloader like me (z2 was my first sony device and i stupidly thought i could buy any z2 and request the unlock code from sony's dev site, so i bought it from vodafone at FULL price and got an unlockable bootloader as a bonus :crying: )
Like @niaboc79 said this things are EXTREMELY complex, technical and very hard to get around... and there's no one with the required skills on xperia sections as far as i know. I would gladly pay like 25/30eur to unlock the bootloader of my z2 if a sunshine like hack was available for it.
And to try and keep this still on topic i didn't unlock my bootloader just because i can't xD
I rooted my Z2 within a few days of owning it (coming from a Z1 which was a dud with horrible touch screen issues )
I proceeded to backup the TA partition and unlock the bootloader, and I have never relocked it, and I think it will stay that way for the foreseeable future.
To me, if the bootloader can be unlocked, it shall become unlocked
I'm currently on official CM12.1 with M5 Kernel, and that made me fall in love with the Z2 all over again, and funny enough this isn't the first time using a custom ROM like CM12.1.
I've used many ROMs on the Z2, from stock to custom and from KitKat to Marshmallow, and in the past there was always a catch in some way or another going to something like CM12.1 or anything based on it.
BUT, that isn't the case anymore.
Using official CM12.1 is just pure bliss. Literally everything is working just as well as on stock. It's like owning a Xperia Nexus, if such a thing existed
No random reboots. No lockups. No force closes. No errors. No bugs.
Awesome
So yes. Unlocking the bootloader was so worth it
Yes indeed, I also had a marvelous experience with 12.1 CM.
The only backdraw was that CM feels so "mainstream" and the ****ty "recovery".
This rom definetly ranges in the top 3 for z2 in my opinion.
There is one thing, that I miss on non-Sony ROMs if the camera is ok, and that is the small apps, yt/media-viewer in particular.
I don't like installing xposed if I don't have to, so the small apps are a nice way to listen to yt while screen off or using other apps in the foreground.

Do you want to stay on MM? There's a good drm fix mod available for O right now, but I've never tried on MM. Not sure what's available...

If you want to stay on MM, you can try some of the early versions of genesis kernel. (version 1.03 should work, I think, can't remember exactly. :/)
The other option is to extract kernel.elf and run it through rootkernel and apply drm fix.
For more info search and read, there are plenty of guides.
Can I use DRM fix (and keep camera quality) on custom ROM (OmniROM 8 or 9)? If so, which one?
Or is it possible only for stock based ROMs?

Good question. I am in this exact situation:
I am on the latest Omni Rom, android 8.
Camera quality is really crappy now.
Did you find a solution?
@rancor187 I haven't tested anything until now but I feel more and more motivated to do so.
Does anyone try drm fix on x compact japan version ?
Hi, there are still people who are interested in KK xperia firmware for SP? A few months ago, I started developing firmware with all the chips of stock xperia 4.4, baced on last cm11 for LB by bagyusz, now it is not worse than xperia ovelay, there are even stamina and color themes in it, at the same time, most cyanogenmod chips are saved. I want to know your opinion, is it worth whether to continue updating it or the xperia KK is no longer interesting to anyone?
Firmware is here
now stock music beat also works

Yeah i'm so glad that this happened I did want the Xperia Kitkat sooo much 2-3 years ago but no one has ever done it. I think it' s great. Thank you for your effort you put on this almost 6 y/o device
Hey, long time no see... I had to sell my xperia z3 last night, so I bought this XT1254 Droid Turbo.... Which is on MCG24.25-5-5 Build.... Android version 6.0.1 Security Patch level January 1, 2017....
I searched around here and found some complex methods for twrp and root, so I thought about posting here... I already did root Z3 unlocked it's bootloader and stuf..
So Is there any less complex method for these things? I don't wanna unlock bootloader for camera quality sake but I'd only like to know about rooting, twrp and a fast android 7 custom rom which is fast / battery saver, supports xposed etc if possible.. (Links would be useful, if someone can) So... Please point me in the right direction..
Else i'm staying stock. Thank you very much in advance.
Anyone???
