Hello guys,
Firstly I would like to inform you that my device is coming in 2 days from now and I would like to take it out of the box and root ASAP, since i cannot live without root since my first galaxy S.
Not knowing Sony's devices I have been reeding quite alot, but all I got was confused.
I've read all sorts of rooting without and with locked bootloader. The bootloader concept is not new to me, since i've had a HTC One m7 5 months ago, so that part I got.
What I do not realize is how come you lose certain rights or apps, or whatever when you unlock the bootloader, but i know you can backup the "TA partition", for whatever that is worth. But, that if i onlyroot i do not need flashing it and if i unlock the bootloader i cannot flash it or it will brick it, meaning i can only really use it on bootloader re-lock, which, again, is a familiar concept to me.
Now, for what matters, and i am sorry for probably repeating the subject, I would like to know the following thigs, if you are ever so kind:
- what is the difference between the FW .55/.69 to the 402 and is it worth not rooting (since i will not be unlocking my BL)?
- how do I get the drivers and what do i need to root it (i prefer the easiest, safest and fastest methodthat is motly or all automatic)?
- can I install any kind of recovery (preferably TWRP, since i used it i've deemed cwm dead) whilst BL locked?
- can i install custom roms on a locked bootloader if the rom does NOT come with kernel changes?
I thank you again for your kindness and patience for my questions, since I know well how boring it can get repeating yourself on Q&A
Hi.
I just got my Xperia Z2 the day before yesterday, and it hasn't been even 15 hours since I rooted my device. And it is my first sony too. I came from Galaxy note ( original) and the rooting process was very different. So I don't know many of your questions and the ones I do now, I'm not sure about.
First I think you can root without unlocking your bootloader and then backup your TA and then unlock and upgrade too a custom build of 402. If your device is on 55/69 you can use Z2 exploit ( I think it was by doomlord.) which root and make a backup of TA. I gained root by this method. then if you ever wanted your bootloader too be like day 1, you can with your TA backup.
as for the drivers, I found a package containing every driver I needed. I don't remember the domain I download it from, but the file name is Flashtool-drivers-1.5-20140318 . I think you can search and find it.
I have a brand new Boost Mobile, Kyocera Hydro Reach, which seems to be a nice little device for the price that would benefit greatly from root access/roms. I attempted to root it via the usual one click methods, with no luck. Kingo crashed the phone, Kingroot failed at like 80%, others didn't work as well. I figured since I wanted to get a little deeper into android development, now would be a good time to start. I was looking into maybe dumping the stock images and building a recovery and such. I tried to boot into recovery (button method) to see what the stock recovery was like, but it booted straight into the OS. Same for download mode. The only alternate mode I successfully booted into was safe mode. I tried to boot into both with ADB as well, but only got the OS again. I'm not sure if the BL is locked or not, and was going to unlock it (there's an option in dev options to allow BL unlocking) with ADB, but it just boots android so I'm not sure.
As stated in the title, this is, afaik, 100% stock, brand new in the packaging. The only time it's been used was during activation. I have QPST which I'm in the process of learning, and the phone has a snapdragon 210 I believe, so it should work. I was thinking maybe I could use it to flash custom images.
Any ideas? I have been rooted on every device since about 2011 or so, and not having my usual apps and such available is annoying me to no end, especially on a device that really needs it. With no stock images, how to I go about developing for this device?
ok so please be gentle here, coming back here after 7 years, from old Windows Mobile days!
I am a newbie to Android and want to root my Z5 compact. The only reason I want to root it is to enable some apps like Greenify and GSam battery monitor to work with all their features enabled. I do not want to flash a new ROM. I am happy with Sony's stock ROM.
Is it possible to get root access without installing / flashing a new ROM?
I have searched the internet but people talk about flashing every time I read about rooting. Then I also saw this thread: http://forum.xda-developers.com/xperia-z5/development/root-automatic-repack-stock-kernel-dm-t3301605
Lots of geeky stuff there which is fine, but again, it seems to talk about flashing the ROM, which I really do not want to do or do not see the need (yet).
Unlock boot loader:
I see that Sony lets me unlock the boot loader from their dev site. I am willing to unlock the boot loader. (Not sure if I want to do that first. Maybe unlocking BL is all I need?)

The only reason to use that guide is to backup ta keys for whatever reason you'd want to do that.
If you're after root on stock ROM the single easiest way is to unlock bootloader, flash twrp 3.0.2, flash xpower 3.0, and that's it. Solid marshmallow with root goodies. Xpower has everything and is deodexed and ready for xposed framework.
just a little more clarification please?

Ok thanks.....that sounds straight forward.....but isn't TWRP a ROM? (sorry, the moment I hear flashing...I think ROM)
And I am looking up xpower...not sure what that is (yet) and why do I need it
I do want xposed framework though.
I wish there was a simple straightforward answer

Twrp is your recovery,you flash through fastboot, xpower 3.0 is the ROM, just a pre-modded stock ROM with options of xperia x addons. Use lite and stock kernel for xpower and you'll be set.
still a little confused

Ok thanks! So my understanding (so far) is :
We "must" flash a ROM in order to root a phone. Did I get that correct?
Since I said I like the stock Sony ROM, you recommended the xpower 3.0 ROM.........but the point is.....I still have to flash ROM.
A little confused here...
I am a systems engineer (my day job). In Linux or Windows OS, if we want root access (to run some software or a low level command, like partitioning a disk etc), we either run SU command and put root's password OR right click and run as administrator......
We never have to install a brand new Operating System to get root access.
Just a total newbie question.....Why do we have do install a whole new OS (flash new ROM) on our Android phones to get root access?

Android is Linux, to gain root in the ROM you have on your phone currently all you need is an unlocked bootloader to run SU, but then you'll be left with a phone that still needs a customized kernel to keep root and a DRM fix for the camera. Xpower 3.0 is that package.
You could really benefit from reading more. Google up on dm-verity and Sony Ric, and fastboot/adb for a little better understanding of what you're getting into without a pre compiled ROM. Messing around with any Android you'll have the majority of the same steps, unlock bootloader with fastboot, flash Supersu, customized kernel.. Etc
Why use a stable compiled ROM?
Let me list down and explain to you why it's best to use a stable compiled ROM. But first you need to understand these few things before you decide to unlock your bootloader and root.
Before Sony Z models kicked in, every rooted Sony device are still able to retain all the features that came together with the phone before it was rooted. When Sony introduce the first Z model, they start to create these things called DRM keys. DRM keys are unique algorithm (i guess i should put it that way) which is attached to every phone the same way an IMEI number is attached to every phone. In short, my DRM keys cannot be used on your phone and vice versa.
DRM key: It's a unique algorithm that holds all the unique features that an unrooted Sony phone boast such as camera quality, X-reality, High Res Audio etc etc.
The moment you unlock your bootloader, that's the moment your DRM keys will be lost. But don't panic, the wonderful devs on XDA have prepared a tool to backup your TA partition (a partition that contains your DRM key) for your own convenience if you want to relock your bootloader.
Then recently Sony/Android come up with new features called Sony RIC and dm-verity. (You may Google what these are all about but to my understanding it is placing limitations to people who root their phones to meddle around with the system settings of thier phone)
With all these "hurdles", it have taken some time for devs here to find a work around and like every fairytale ending, they manage to find a way.
Now you're wondering if you can actually root without flashing another rom. Good news for you: you can! There's a guide that will teach you how to actually root and apply the work around after unlocking your bootloader and rooting.
.. But ask yourself what's the point of going through the hassle of rooting and your phone is not tweaked for performance or for theming purposes?
That's when people flash roms and in Z5 compact's case, XPower is the best rom there is. It gives you all the performance tweak you need to make your phone lag free, it has a lite version that removes all the unnecessary system apps you can't delete without root, it gives you an option to add themes and framework from Xperia X with all those work around in place.
For your second question: why is there a need to install TWRP?
TWRP is a recovery tool which is a need for all rooted phone. It's also a tool for you to backup and restore your current rom so that you can rollback to the last working configuration if your phone went into a bootloop etc. Plus i believe all these guides require you to actually use TWRP to flash the SuperSU to successfully root your phone.
I hope this explains your doubts.
Thanks a lot but...
firdyRAY, thanks a lot for the comprehensive reply to my questions. And yes, it has shed a LOT of light on my doubts.
I googled Sony RIC and dm-verity:
I could not get find much on ric
Dm-verity seems to me a way to check if the boot image has been modified from the last boot, and if it has, stop from booting. Sounds like a good idea until we understand that to flash a ROM dm-verity needs to be bypassed/turned off.
So to compile what I have understood so far:
By unlocking bootloader, you lose DRM keys. There is a way to backup DRM keys which are in the TA partition, but this is to be done BEFORE you unlock bootloader. Good that I have not done anything to my X5c yet.
The next steps for me would be to look into XPower 3 ROM…which I did and here is what I found out:
http://forum.xda-developers.com/z5-compact/development/rom-xpower-v1-0-aroma-debloat-custom-t3371100
First, what's up with the scary looking warning in RED right at the top of the first thread. I did read the OP and the second post, I did not see anything in there which IF I missed will cause my phone to explode! That is probably posted to make noobs read all instructions, right?
Second, I do not see any step in there to backup the DRM / TA partition. I guess the dev is assuming the phone already has lost the DRM, right? So I gotta find instructions on how to backup DRM / TA
Then I searched for problems in this ROM and seems to me that the fingerprint sensor is reported by many to be not working and/or buggy. I rely on the fingerprint sensor day and night. I have many apps which rely on that, like lastpass. That would be a major deal breaker for me.
So going back to stock ROM option…I remember you said "There's a guide that will teach you how to actually root and apply the work around after unlocking your bootloader and rooting."
Could you please post a link to that?
Thanks again!
I think this is a pretty great thread rajdude. It's getting people to spell out a lot of information to noobs like us that it seems most posters have taken for granted over time.
I'm a complete novice at all of this. Sort of gleaning information as I go along, but I used this guide: http://twigstechtips.blogspot.hk/2016/04/sony-z5-compact-root-without-losing-ta.html?m=0
Along with this guide: http://forum.xda-developers.com/xperia-z5/general/guide-rooting-unlocking-bootloader-t3354307
The first guide is pretty basic step-by-step instructions. It unfortunately occasionally kind of skips over a couple very small things (that will be clear as you go along), or occasionally words things in such a way that might not be completely intuitive, but maybe that's cause I need things explained to me like I'm five sometimes. Any time I might have had a question about something in the the first guide, I went to the other and found the answer. It didn't take me long to get the gist of the whole thing though, and overall, it wasn't as scary as I thought it was going to be. It'd be fantastic if someone created a video walkthrough, but so far as I know, no one has done that yet.
The guide will help you back up your TA Partition where your DRM keys are stored, unlock your bootloader, root your device, and then restore your DRM keys. In order to do this you need to downgrade to Lollipop (if you're not already on it), and then upgrade back up to Marshmallow. It will also install TWRP (which I had no clue was installed until I went into "recovery mode" by pressing UP when I saw the LED flash yellow during boot). There may be an easier way to go about this whole process, but this is the process I used.
Before jumping into anything, I'd hold off until you heard more from firdyRAY or someone more experienced. They may look at the guide I linked and be horrified.
And yeah, I haven't installed xpower yet for the same reasons you haven't. Sounds like there's even an xpower 4.0 that was released recently, but still seems kinda buggy. Being rooted with stock I've been able to give Greenify access to root. Install Adaway (which was worth getting root to begin with). Install sound/music mods like DiVA-X, Viper4Android and Dolby Atmos. Install Titanium Backup. And make a few other minor tweaks (that I've since reversed). I still don't know much about custom ROMs and all that jazz, so I'm holding off until I get more understanding. I'd love to install the xpower ROM (when the bugs are worked out), and maybe some sort of sound ROM. I also need to get more understanding on some of the other vernacular like what exactly a "dirty flash" is.

sony ric is a layer of security for sony roms so that they can protect nfc and fingerprint stuff. samsung and htc have there own variants as well.
yes lol the big red lettering is there to make you read, although hes not far off on the melting your phone part, the s810 is ridiculously hot.
the xpower thread doesnt not include the drm backup instructions because: 1) you need bootloader unlocked to flash it. and 2) because it includes the drm fix in it so you dont have to backup your ta keys.
the fingerprint sensor bug is on any bootloader unlocked phone, the hardware fails after x amount of hours and requires a reboot to work again. xpower is a stock rom, the only thing different is its pre-rooted, de-bloated, and deodexed for xposed to work. we have a separate thread for the fingerprint sensor bug and its been solved.

Sony RIC main function is to disable /system write even you got root permission(you still able to do /system write but after a reboot will restore to original). There is a workaround but very trouble, TWRP recovery file manager can bypass Sony RIC(it works in the old day for me, not sure about now). BTW, all 3rd kernel should be disabled RIC nowadays. For any regular computer, there is no hardware or software lock to prevent you gain root access in linux but there are many such trouble stuffs in the android world... lol
I'm running XPower 3.0 Full as a daily driver since June and been very happy. Battery life, stability and speed is good.
Please note, that you MAY lose your warranty when you lose your DRM keys. That's why I didn't unlocked my phone before there was a way to backup TA partition. Now I'm after warranty repair, and before it I was able to fully restore stock ROM with DRM and all features fully functional. In my country, there is only one Sony approved repair center and they check DRM keys before repairing anything - even if it's mechanical fault.
When I had Z1c in KitKat days, it didn't had dm-verity and Sony RIC. It was possible to gain permanent root with bootloader locked, so I was happily using stock ROM and kernel. In Z5c case, first thing I tried was to do the same and it was possible (just backup TA, unlock bootloader, and flash TWRP with patched kernel (dm-verity and Sony RIC disabled) to begin with), but going XPower way was much more confident - I didn't had to think about removing every bloat app. I just flashed lite version in June and I'm using it till this day without any problems at all
Another thing is that you lose OTA (Over-The-Air Update) functionality when you unlock bootloader and disable Sony RIC and dm-verity. Updating to newer versions of firmware, even on stock ROM is problematic when you modify it.

It's simply not possible. If you are rooted you can't apply OTA updates and neither should you.

That's just what I wrote - just put it in another words
I have owned my xperia x compact since June 2017, the first thing I did with it when I bought it was flash the UK firmware and root it. The phone has operated with out any real issues since then, but today I woke up to my phone on the charger showing a back lit black screen. It was unresponsive to any inputs so I rebooted it (power button, up volume), and it would just load to the xperia splash screen freeze then reboot ad nauseam. I am tempted to use the xperia companion to attempt a software repair but I am afriad if I do I'll get updated to oreo and not have a working camera. I did back up my keys when I rooted my phone but I did not change to the bootloader from factory.
Any input as to how I should proceed would be greatly apprechiated
Thank you
Do you have twrp? Do you have a twrp backup? If so, just boot to twrp, try factory reset, and if it boots after that, just restore your backup. If you don't have a backup, and you don't want to lose data, it's hard to know what to do, especially since you don't seem to have a clue what caused it. You can try to flash an ftf with Flashtool, excluding everything except 'system', (and making sure to check nothing in 'wipe' box'. Other possibilities, if you have recovery, is to try uninstalling things like Xposed, Magisk, Substratum, etc...
Thanks for the input, as stated I never changed the boot loader so unfortunately I do not have twrp and thus no images to restore.
I would like to preserve my data if possible but biggest concern is losing the camera. From what I gather using the Xperia companion will update my phone to Oreo likely loosing my ability to root but also locking out the camera. I have a back up of my DRM keys but if I am not on the factory marshmallow rom I don't think I'll be able to restore them. So is there a way to restore the phone to original factory marshmallow firmware?
Marshmallow ftf / Flashtool. I'm sure you can find one out there. Also, you can upgrade to O and your camera will be fine. Drm keys just make it a little better. And you can root with Rootkernel, and use your ta backup to mount onto Rootkernel, so camera will be just like stock. See here - https://forum.xda-developers.com/x-compact/how-to/stock-8-0-root-recovery-t3747479
Thanks for your help I really appreciate it. If I can have camera and root functionality on Oreo then I might as well upgrade.
Its been awhile since I've messed with this, and I am on a different computer. Hopefully I can get this phone up and running and out of this boot loop.
Also looking at your guide the modded boot images offered are older than the firmware currently offered on xperiafirm, do I need to find the specific firmware offered in your guide instead of the one offered on xperiafirm?
It's pretty easy to do once you're set up, but I'll see if I can post an updated one tonight.
Thanks, I do not recall having much issue getting the device unlocked and rooted with the guides here on XDA. Then again the phone was fully bootable at that time so once plugged in, windows and the xperia companion took care of the drivers. I am in the process of familiarizing myself with all the ancillary bits which may not be explicitly detailed. I suspect I will need to put adb and fastboot on this new PC, was going to use snoop05 15 second installer but all his links are dead.
