[ROOT] after AndroPlus does not compile new kernels anymore - Xperia Z4 Tablet Q&A, Help & Troubleshooting

Since @AndroPlus abandonded his kernel for karin devices I still want a recent ROM rooted.
At the time I unlocked the bootloader I was not aware that I should back up the TA so mine is broken anyway and I also did not find a DRM-Fix suitable for the stock kernel.
I am too lazy ATM to learn how Androplus or others fit a DRM-fix into their sources and build a kernel myself with the latest SONY-sources.
I do not care much about DRM-stuff anyway and found for me it would be better to get the latest ROM and root it.
For this I use @munjeni 's ta_poc. This worked well several times on my XZ-phone.
Since I do not have a TA-backup I fake one. Inspiration came from @shoey63 in https://forum.xda-developers.com/showpost.php?p=69972315&postcount=21
Just reversed the restore:
Code:
adb shell
su
dd if=/dev/block/bootdevice/by-name/TA of=/data/local/tmp/TAfakebackup.img
exit
exit
adb root
adb pull -a /data/local/tmp/TAfakebackup.img
Now use this as input for the ta_poc and you get a boot image without DM-verity for your Z4 tablet.
No DRM-fixes though!
Flash the resulting boot image, a recovery and root the device.
FWIW: I could not adb reboot recovery - I have to fastboot boot TWRP-3.0.3.0-lineageos-karin_windy-20170304.img from @andralex8

Thanks for sharing your work here. I'm sticking to Marshmallow myself, because that's fast, stable and has Xposed, but if I'll ever upgrade, I'll use your root solution.

I'm sorry i have not understood how you faked drm keys? The link you provided above is about original keys.

WARNING: THESE FILES ARE BASED ON THE OXYGEN OS 2.1.1 FIRMWARE, PLEASE ANALYZE YOUR DEVINFO IF THE VERSION IS DIFFERENT TO MAKE SURE NOT BRICKING SOMETHING!
I have not upgraded my device to 2.1.2 yet because there have been some issues with the newest firmware.
Tested and confirmed working on:
OxygenOS 2.2.0 - thanks to @pryggi
OxygenOS 2.1.1
Hydrogen OS 1.2.0 - thanks to @fareed_xtreme
I looked at this thread, thanks to Naman Bhalla for this great work.
and found out that the file attached to this post is the answer to my problem, described in another thread.
After the whole day of work analyzing and dumping and saving via adb from my device to the pc and the other way around i finally did it.
On the frist screenshot is my situation before flashing the new devinfo, on the second after flashing the devinfo from the thread mentioned above.
By changing the bits with a Hex Editor of your choice, or by flashing the files below via dd:
Code:
dd bs=4096 of=/dev/block/bootdevice/by-name/devinfo if=/sdcard/oneplus2-devinfo-factory.img
The output should look like the following:
Code:
0+1 records in
0+1 records out
1024 bytes transferred in 0.005 secs (204800 bytes/sec)
You can restore your OnePlus 2 to a factory state while still having root or unlock your phone again without having to wipe it! :highfive:

Also to segv11 who already managed this in the OnePlus One and Nexus devices
wow nice job m8
sent from rooted phone
Modified the same location using a HEX Editor (root) whilst on the Hydrogen OS 1.2.0 and I must say it works.
Screenshot Attached. Good Find @thedropdead
Thank you and thanks for testing it out on Hydrogen OS @fareed_xtreme
It is not a Revolution like CM13 on the 1+2, but its helpful for people like me who use their developer devices as daily drivers and still want to lock and unlock the device because of security reasons without wiping the whole device.

Thanks, I was waiting for this for securing my OPT. Has anyone tested, if it works also on OOS 2.2.0?
Just to clarify, the dd command should be executed in TWRP console?
Would be cool if someone could make an app for this like the Nexus devices have:

Hello pryggi,
It should also work on OOS 2.2.0, you could check that by dumping the partition (by reversing the dd command) like this:
Code:
dd bs=4096 if=/dev/block/bootdevice/by-name/devinfo of=/sdcard/oneplus2-devinfo-oos220.img
And looking at the file in the hex editor for differences or by posting it here and i can check it for you.
I have executed the dd command from ADB Shell with the Phone connected via wireless ADB.
You can also execute dd in the Android Terminal Emulator App.
Thanks for your reply. My device is already unlocked. As I don't have a computer with ADB/drivers at hand right now, I managed to run the dd command in Terminal Emulator app after elevating with su. Result is attached. Viewing it in hex seems to confirm, that at least the locking bit seems to be in the same position.

Thank you for the Dump, i can confirm that the bit is at the same position and the unlock bit is the same.
I compared the file attached at my first post with yours and they are identical ( see attachment, sorry its german, meaning is they are identical).
So by flashing the factory.img from my first post or unchecking OEM Unlock allowed in the developer Settings your device should be locked again and can be unlocked by flashing the unlock.img via dd in ADB or the Android Terminal Emulator within the Phone.
Thanks for the further explanation. I was just wondering about this OEM Unlocking switch in dev options. What would happen, if one would use dd and the factory image file to lock the bootloader and leave the OEM Unlocking switch still unlocked...
I also am interested if this type of locking-unlocking can be done in TWRP... If it can be done there, then it does not offer any benefits in security, if my logic is correct. Although, I might be drifting off topic here.

As i can remember i tried that too, by flashing the factory image partition via dd and leaving the switch on, the switch gets toggled off when rebooting, because the switch is just the representation of the unlocking bit in the partition. So when it is turned off, the software will set the bit to zero, means the device will get locked on reboot. Turning the switch on will not override the bit and the device can boot unlocked and the switch will stay on.
It is hard to explain
Your Idea about doing the same thing in TWRP since the ADB is available there is interesting.
I think the problem here is, that once you onlock and flash a custom recovery via fastboot, and relock the device, you already tampered with it, and twrp does provide much more options than the stock recovery image (ADB commands, ...).
So the problem here lies in flashing twrp.
I solved this problem by keeping the stock recovery and locking the device via the image file.
Once i want to use twrp, i unlock the phone by using the unlock.img and use "fastboot boot twrp.img" to boot twrp to backup my device or some other action.
I know that this means if my device gets bricked in this locked state with stock recovery i will have to unlock it normally, but before making any important changes to my software i always unlock my device first in case something goes wrong and with the stock recovery i could not even flash anything so making huge software changes requires me to unlock my device and boot twrp
Hope that this post helps somehow

That is right, i just included the notice in the first post so nobody can tell me i have not told them
It is also possible that OnePlus changes the layout of that partition in one of the upcoming updates/releases and that is why it is still mentioned in the first post, thank you anyway.
@thedropdead I've a question: I should use the "modified" devinfo.img AFTER I go back to stock, if I want to unlock my phone without wiping data, right ? So I go back to stock, flash in fastboot or in terminal emulator the .img, and that's good ? I'me unlocked without data wiped ?

That should be the plan if i have understood everything right.
So you are on the custom ROM, want to go back to the stock ROM?
If that is the case i do not see why you should want to flash any image.
You can use TWRP to wipe and then flash the stock ROM, your phone should still be unlocked right?
Please someone correct me if i am wrong.
It would be great if you could tell me what you are trying to achieve.
The unlock image had the purpose to help someone unlock their device if they have a rooted device but have locked it after flashing everything for security reasons.

Okay thanks for the clarification.
In the Case of using some unbrick Tool and thus resetting everything including recovery to stock your phone should lock on the first stock boot.
Once it is locked and you do not have root, which would be the case, you have no possibility to flash the img via fastboot or the emulator.
so in conclusion you are better off with wiping and flashing via twrp so you can still flash something if anything goes wrong
It works on OxygenOS 3.0.2 too. I edit the same location using a HEX Editor. And everything is fine.
Hey guys, sounds like this is exactly what I've been looking for. Thanks for figuring this out.
But, I'm a bit of a noob, so can you break it down into like a hundred very clear steps?

Is there a way to get recovery on marshmallow with locked bootloader?

I have done: revert to lollipop, root, install recovery (NUT's dualrecovery), flashed eXistenz (3.5.0)
And I would like to get a working recovery.
current state
ROM: 6.0.x Marshmallow based eXistenz with root access, version 3.5.0
Bootloader: locked (would like to keep it that way, because warranty)
Recovery: none? (tried 'adb reboot recovery', various volume/power key combinations and some apps from market)
my questions
1. I've heard that NUT's dualrecovery won't work on Marshmallow, so which one will?
2. Is it even possible to have recovery on marshmallow rom without unlocking bootloader?
3. If I unlock bootloader is it possible to relock it? (I have TA partition backed up)
4. Why do some roms require unlocked bootloader, but some work with the locked one?
Thanks
1. That's true, NUT's dualrecovery works on lollipop, but not on marshmallow and trying to install it will get you into a bootloop.
2. It's possible, since serajr was kind enough to make it for us. You can download it here.
3. We're almost sure that backing up your TA partition (and restoring it if you need to) will get you your warranty back. Just make sure you downloaded the right version that works on marshmallow and dry-run the backup to be sure it successfully backed it up.
4. Some roms have features that require custom kernel, and to have to unlock your bootloader to be able to replace stock Sony kernel with a custom one.
Hope that helps you understand your phone a little better [emoji57]
Thanks

Just want root access; happy with stock ROM. Possible?

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?

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.

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.

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:

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.

Root E5823 6.0.1 32.2.a.0.305

Hi All,
I am looking for a tutorial that explains how to root the cellphone build under 32.2.a.0.305 running with Marshmallow. I haven't found any topic that state someone succeeded to root this one. Any chance someone can give me some guidance. On some other website it is mentionned that we cannot root it for the moment. So I was thinking maybe downgrade it and go back to Lollipop? But even for that I need some guidance.
Thanks in advance.
Cheers.

Theres a perfectly detailed guide in general section , you should downgrade to lolipop so you can use the temp root tool to back up drm keys before unlocking the bootloader , but if you dont care about drm keys , you can in fact just skip to the boorloader unlock part and root. Its so simple , but i would suggest going through the whole proccess and back up your drm keys cuz once lost , forever lost so ... Yah

Hi Madshark
Thanks for your prompt reply. Appreciate it.
I'm at rookie level in terms or rooting smartphone, so I don't know even the basics. Can you send me the link of the "detailed guide" and also explain me what does the "drm keys" stand for?

this is the link to the post that I used and followed its instructions to root my phone personally.
http://forum.xda-developers.com/z5-compact/general/how-to-backup-restore-ta-partition-root-t3479532
if you lose DRM keys (and that happens when unlocking the bootloader) then some functions in the device will stop working like Bravia engine, Track ID, etc and on our z5 compact some say even stock camera stops from working, and when you lose those keys you can NEVER get them back because each device has its OWN TA partition that includes its OWN DRM keys and no other device has the same so thats why each and every one who owns an Xperia device must perform this TA backup in case they ever wanted to get back to stock (unroot and relock bootloader) they can restore these keys and functions to factory functionality. if you dont back them up and unlocked the boot loader then you will never get some functions to get back to working properly if you ever wanted to get back to stock and relock your boot loader!
However; there is some thing that is called DRM fix in certain roms that when you install these roms, you will not feel like you lost your functions because they already include a fix that behaves like the DRM keys.
still, losing your DRM keys will cause your device to lose its warranty and if you didnt back them up then you will never get it back even if you relocked your bootloader. so I personally backed them up because my device has a 2 year warranty and I dont want to waste them if any thing goes wrong I would restore them and send it to get fixed.
yet the only problem is warranty to me so if you have no warranty or dont care about it you can skip the back up process but yet again I dont like taking chances so just back them up its a 2 minute thing.
and I say again, all stock based roms in this Z5 compact forum have drm fix...
and to give you my personal opinion I dont like the Xperia z5 compact rooted because as I saw, there is so little roms and so little kernel variations and all the stable roms are based on stock MM firmware and CM roms arent fully stable yet , (they are but they have bugs that I hate having) and I only rooted so i can increase the volume of my phone speakers and headset and increase the strength of the torch but it all turns out to be that all sound mods have bugs and torch mod only work properly on any thing but STOCK ftf but any thing besides stock ftf isnt fully stable so I dont see any point in rooting this device I so regret buying it I should have checked how little the modifications are that can be made on it I owned Z2 and HTC devices in the past and boy! if I wanted to try different things every day for the past 2 years I wouldnt have finished by now there is sooo much to test and so much to try and to customize ...
the only rom that can be customized and can be enjoyed as much that we have is Kryptonian - the rom of awesomeness!
I hope I was helpful

Very helpful ! Thanks v much - I'll let you know if I succeed!
Ok, 2 more things.
Probably the most important: warranty has nothing to do with DRM keys, unlocked bootloader or what more. Sony is not/never gonna repair smartphones when there're problems caused by custom ROM or kernel, they're not gonna fix a bootloop caused by a bad flashing procedure and so on. But it's not true that you're automatically losing warranty by unlocking bootloader or getting root access.
Next to that, you don't have to go through that process of backing up your own TA, if you don't want. It's much easier to root and flash a kernel with DRM keys patched. Procedure to root is really simple. Flash new rom, unlock bootloader, fastboot to flash compatible twrp , flash supersu, flash modded kernel, done. There're already quite some tutorials to guide you through this proces.

Yah well if the bootloader is unlocked and the system has modification on it , they have every right to refuse fixing it for you because its hard to prove that what bricked the device isnt some modification that you made... Unless they have a really good heart , i had a z2 before and it was rooted but the ftf on it was custom but was on it for like 7 months and all the mods were working properly untill all of the sudden it wont turn on so they told me that what i.did caused it but i didnt do anything wrong i know they lying but can u prove it!? No..
Hi guys,
How do I flash the boot.img using cmd and fastboot ?

first you gotta download ADB folder
you can find it here if im not wrong : http://forum.xda-developers.com/showthread.php?t=2588979
then place the adb folder in C:\
I think it automatically place it there when installing so no need to do that if so
2. go to cmd (start - type in CMD) and once it launches direct it to where the adb folder is "cd c:\adb" without the quotes of course
3. to flash boot type in "fastboot flash boot boot.img" without quotes and one space step between words only.
4. to flash recovert just type is "fastboot flash recovery "recovery name".img wihtout the quotes and copy recovery name exactly the way it is.
that it
keep in mind that any time you want to flash any thing , that thing must be inside the adb folder for example ,boot.img file must be there in the adb folder with all the other files when installing adb, and also recovery and every other thing you want to flash using fastboot.
hope this is helpful.
Hi madshark, thanks again for your help. I have been able to flash the boot img and then rename twrp into recovery and flash it as well.
Now I'm stuck the device cannot reboot so I cannot transfert the SuperSU files in to the device...
And when I type adb devices in cmd, it do not mention the device ! Seems that I'm facing an issue.

well youre new, mistakes like these happen Ive been there, sorry for the late reply XDA isnt giving me notification
any way, make sure after backup TA (which is on lolipop firmware) you gotta get back to original .305 firmware (MM) the process of you getting back to lolipop in the first place is so you can use Ivoyroot tool for temporary root so you can backup your TA partition, once that is done you must get back to .305 because you are flashing a kernel (boot.img) that is for build .305 I guess the guide guy didnt mention this?
second when I said copy recovery name as it is I meant what recovery name you have for example
fastboot flash recovery twrp-3.0.2-0-E5823-20160417.img
thats my recovery name the one that I downloaded, yours might say some thing else its OK I meant copy YOUR recovery name to CMD the way it is exactly in the ADB folder
and now your stuck, if your bootloader is already unlocked, just flash .305 firmware with flashtool the same way you flashed the lolipop firmware, once that is done, do the first boot settings and once device is launched into the software , just flash boot again
make sure you follow instructions to the POINT, so you gotta turn of your phone, press the volume up button keep it pressed while connecting your phone to the PC and flash boot and recovery and thats it
and after youre done with this process , then you turn on your phone connect it to your PC and place the superSU zip file in it and then go to recovery and flash it
adb isnt recognizing your device?
thats weird if you just connect your device nothing will happen, so you turn off your phone and press the volume up button and connect it, (thats how you enter fastboot mode) and if still doesnt recognize then do what I told you to do already and see what happens next
keep me updated and if its urgent just send me a PM because I dont see notification otherwise...
Thanks Madshark for your help, it has finally worked!

PROBLEM with Sony Xperia Z5 Compact

Hello everyone,
As a first time noob trying to root my Sony Xperia Z5 Compact (E5803), I lost my DRM keys since I made no backup. Now I am searching for a way to get the functionality of the camera, bluetooth, x-reality, and more back. I currently still have an unlocked bootloader and am running stock Android Nougat (32.3.A.0.376). Can someone please tell me how I can restore the DRM keys and the TA partition? I don't need root anymore, and I have had no luck making TWRP recovery work.
Please, I just desperately want my phone to work as it did before.
Thank you very much in advance!

If your DMR Keys are deleted and you have no backup of them, than there are gone, it is not possible to get them back.
You can use a custom kernel that 'tells' the DRM keys are there, that fixes your issue.
Somewhere there is an instruction how to build your own kernel (super easy) with DRM fix. I couldn't find it so good luck looking for it

Thanks for replying! Yeah, I assumed that would be the case. But I found this post that says I can flash a "drmrestore" zip package so I can simulate that the keys are still there: https://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
The thing is, in order to flash it, I need TWRP recovery, right? I have been unable to successfully install TWRP. Is there an easy way to install it?
Thanks again!

Thanks a lot for replying! If I find this post where I can create my own kernel, I will have to unlock the bootloader again and flash the new custom firmware using flashtool, right?
Also, will I have to downgrade to Lollipop, since Nougat is pretty new on Sony phones and there's no drm fix for that?
Thanks again!
My advice to you in your situation.
dont worry about building your own kernel. I have attached the Androplus Kernel for z5c, nougat build 376 - flash this kernel onto your phone.
You have adb right?
1. unzip the attachment on this post to get the boot.img file (the androplus kernal for your current build)
2. Turn off your phone, and unplug from USB
3. Go into fastboot mode - Hold Volume Up and plug in USB cable, notice LED turns blue.
4. Run the commant "fastboot flash boot boot.img" (takes about 2 seconds to complete)
Boot your phone, go into Settings -> Display -> Image enhancement . Then check X-Reality is working by toogling it off and on and see if the image of the tomatos changes colors. If the tomatoes change color, then congratulations - you dont have to worry about your lost DRM keys! You have full functionality!
Im pretty sure everything will be ok after this. It's a great kernel - good battery and all the functionality is there.
You do not need TWRP, you do not need to downgrade to lollipop or marshmellow or anything like that.
Will try!

I apologize for replying with my report this late.
It turns out I re-locked my bootloader in the process when I flashed Android Nougat, since I had bricked it temporarily. To do the procedure you mentioned above, I need to have it un-locked, correct?
If that is the case, when I try to unlock the bootloader, I cannot access fastboot because whenever I press VOL UP key with adb, the light flashes blue and then red and then boots into the OS normally. Same with flashmode (the light turns green, and then red, finally booting into the OS).
Does anyone have a solution for this, please?
Thank you very much!
Go into Developer settings and make sure the allow OEM unlocking option is enabled. Then follow sony's unlocking instructions. Once thats done, try again.

OEM unlocking option and USB debugging were already enabled. It should have technically been working by now. Could it have something to do with some drivers I have to re-install?

I was able to bypass the blue-red notification light problem and was able to unlock the bootloader and flash the boot.img file, so camera and X-Reality are working normally now!! Thank you so, so much for your help!
I have one question, please. Will I lose the camera functionality and X-Reality, etc., if I re-lock the bootloader?
Also, in the future, if there are any updates to the Nougat OS, will they break these functions once again?

You can lock the bootloader again, however I dont think there is any point in doing that. You should not use auto updates anymore, or yes, it will break those functions. Auto updates technically never work on any rooted phone. If you want to updateto a newer build you will need download it and flash it with xperifirm/flashtool (which is a good reason to keep your bootloader permanently unlocked). You've already lost your DRM keys, so I think your phone should remain a rooted model for the rest of its life. Really no point in going back to stock with no keys.
Personally, I am also running 376 build, with the androplus kernel, debloated (i debloated with another kernel, once finished, then used androplus). I removed even the software update and support apps. I applied the volume fix (if you are having the low volime issue?). Considering this phone is running Android 7.0, already has the best kernel (androplus), i think its safe to leave the phone like this for the remainder of its life. I dont really care about any minor upgrates to nougat, and we are not getting Android 8.0. so I recommend if everything is working now, just leave the phone in its current state. will save you a lot of stress.

Thanks for replying. My phone is actually not rooted, I just checked with the Root Checker app from the Play Store. Besides, there is no SuperSu or Superuser apps installed. Additionally, in the Xperia Service Menu, it says "Bootloader unlock allowed: Yes," so I guess this means the bootloader was re-locked somehow when I flashed the boot file.
Form the looks of things, I'm back where I started before losing the DRM keys, minus the stock Sony music equalizer (in which, even though the controls can be changed, the sound itself doesn't change). I'm guessing there's no fix for that, right?
Anyway, I checked the volume and it sounds fine, just like it did before.
Thank you so much for your assistance, Dean F!

Correct your phone is not rooted because the androplus kernel is not a rooted kernel. It is simply a custom kernel with some optimizations, and includes the DRM fix. If you want to do some maintenance while rooted, flash a rooted kernel (i will attach one to this post for you). Once rooted do what you need to do - like debloat,remove apps with Titanium Backup, and once you are finished - flash the Androplus kernel again. The idea is just to give you root for a tempory peroid to customize your device, before going back to a safer, optimized, non rooted state for every day usage.
If you have androplus kernel, i don't believe it is possible to be in a state where DRM functions are not working, as it contains the kernel DRM fix.

Excellent, I see now, thanks!
Well, what I wanted before starting the entire process was a permanent root solution, one that would allow me to access features like Root Explorer on ES File Explorer, or extra features in Link2SD and such, when the opportunity arose. That is what I did with all my previous smartphones, even a Sony Z1 Compact, but this has been the hardest phone to root I've ever handled.
After all the trial and error I've faced, I will take your good advice and leave it as is for now. In the future, I will flash the rooted kernel when I need to use those functions, and use the androplus kernel you had sent me previously to get it back to normal.
Thank a bunch again for all your help, Dean F. You revived my phone, so to speak!
Cheers!
