[Q] Help with installing lollipop on unlocked phone

Hello !
I recently bought a used Z3 6603, and wanted to update it to lollipop.
But it seems it has a unlocked bootloader (according to service menu) and when i recieved it, it was factory reset, but some 3rd party apps were still installed.
One of them Super SU, so it was rooted.
I was told that i could update the firmware if i just used the Full Uninstall feature in Super Su, so i did that.
I still can't update using sony companion, becouse it knows the software is not the original one.
And i cant reinstall super su, its saying that there is no SU binary installed and the program cant install it.
I have flashed phones before, but it was really a long time ago, so im asking for some help to fix this.
Its running 4.4.4 build 23.0.1.A.5.77 and stock rom i think.
Please tell me what to do, and what info you might need !
I want to have the phone in lollipop, but everything stock, no root, no bootloader etc.
And somewhere I read something about DRM keys. Please help me with fixing that aswell thank you.
Regards ImmoralCore

Your DRM keys are lost forever.

Ok, so they are lost even if I use the first backup that was made by the person I bought it from ?
DRM=Hardcoded=Once unlocked, always DRM free, even if you use the recovery image ?
And the rest of the questions, what am I supposed to do to get stock lollipop?
In the matter of fact it does not matter if its unlocked or locked, I just want legit lollipop, with the possibility to update regularly. (But if root is possible at the same, it can still be rooted)
Thanks for your reply !

You need the TA backup. Not system backup.
And careful not to restore some other TA.
If the previous owner backed up TA, good. If not, no chance to recover them.
Download your specific firmware in ftf format and flash it with Flashtool.
Make a clean install.
You cannot recieve OTA with an unlocked bootloader, only if you relock, but there is no point in doing that if the DRM keys are lost.
So, from where you stand, keep it rooted and unlocked, because you can do much more with it : Custom ROM' s [at the moment stock is best]...custom kernels with recovery...mods...etc.
After you flash the ftf, flash via adb a custom kernel with recovery and from recovery flash SuperSU update, as a flashable zip, that will root the phone and install SuperSU.Search also for busybox flashable zip.

Ok, I will try that then, but if I use flashtool to update to lollipop, will I still be able to root easy, or should I reinstall 4.4.4 clean, then root, fix recovery kernel and everything, and then lollipop or what goes first?
Does flash/kernel etc affect the fact that it has an unlocked bootloader ? do i need to do anything with that, or do it stay unlocked?

If you have unlocked the bootloader it is always a trivial matter to root.
Just flash an insecure kernel.
If one does not exist use [NUT]'s online kernel builder to make one with recovery incorporated in it. Its very straightforward and an automated process.
So, update using flashtool, flash your custom kernel, and you have root and recovery.

1. Sorry for my noobish question, but define insecure kernel?
2. Did I get it right? I read about ppl downgrading their phones to 4.4.4 and then installing stuff. And for me it does not matter wich version it is, becouse the unlocked bootloader makes it easy to flash, even what version you are running?

1) a rooted kernel.
2) If you have unlocked there is no need to follow any of the locked bootloader guides, they are a waste of your time. One of the points point of unlocking the phone is to easily get root. You just flash a custom kernel to gain root.
If you have a locked bootloader then you have to go through all the fuss of downgrading etc etc.... but with an unlocked bootloader its so easy and straightforward

D6603 - Supersu + Xposed keeping DRM Keys [STOCK ROM LOLLIPOP]

Alright guys, I'm sorry since there already are a lot of threads about how rooting this device, but from what I've seen it's a complete mess and I can't really understand how to do things properly without ruining my phone.
I need root access with supersu, xposed and lollipop, without rosing my keys, staying on the stock rom.
I read that I should backup, downgrade my firmware to kitkat, root with a one click tool (without losing my keys?) and flash a lollipop update (one of those posted there?)
Then, after having rooted via the one click tool and backupping the keys, am I really safe to flash stuff and then restore them? (always staying on stock)
Now:
What makes me lose the DRM keys? Will getting Xposed and Supersu make me lose my keys?
Is there, by chance, a way that makes me root the phone and install Xposed on lollipop without ANY worries about the keys?
Could you please answer my questions or just tell me the best way to do this safely? I'm really scared of breaking my new device, with my old Samsung I flashed what I wanted without any worries >__>

You will only lose DRM keys if you unlock the bootloader.
Flash a KK FTF ending in .93 using flashtool from flashtool.net
Root it using Giefroot
Install [NUT]'s dual recovery
Flash a prerooted Lollipop ROM.
Done

Is this KK FTF rom a right one?

Found NUTT's dual recovery: http://forum.xda-developers.com/z3/development/z3-xzdualrecovery-qa-t3014206
How are prerooted Lollipop ROMs? Are they just the stock rom with supersu installed.? And then I just have to flash Xposed via the recovery?
Also, could you please link the right prerooted Lollipop ROM? I can't find that one

Alright it's perfect
There's just one thing that didn't happen before...
Messenger won't open when I use the facebook app, it uses the ugly standard app by default and I don't know how to change that, I've already tried unistalling both, disabling Xperia with Facebook and it didn' work!
I don't know if it's a feature of the pre-rooted ROM or something else, does anybody know anything about it?
It never happened on my old rom, can't find anything about it on Google

did you installed Xposed? which one worked?
reading all about rooting z3, and I also want to make sure I have all files needed before starting.

did you do a back up 1st, if so what did you use? cant seem to back up everything like full image
sorry about asking about xposed again but they are so many versions which one and which apk (read about lots bootloop if used the wrong one)
thanks

Upgrading Xperia Z5 Dual from 32.1.A.1.185 to 32.2.A.0.224 without loosing ROOT?

This week sony release the new upgrade build for MarshMallow 32.2.A.0.224. I am currently using build 32.1.A.1.185 with ROOT ACCESS which I did using this ROOTING GUIDE for XPERIA Z5
http://forum.xda-developers.com/xperia-z5/general/guide-rooting-unlocking-bootloader-t3354307
I have read here in on this page http://forum.xda-developers.com/z5-compact/general/root-partially-upgrade-to-32-2-0-224-t3391235 , that one of the guys upgraded to this new build without loosing ROOT ACCESS to his Z5. All I wanted to ask should I continue like him Upgrading from my PC/PHONE to the new build without loosing root access or is there going to be some long lengthy UPGRADING GUIDE for this new Z5 Build.?:silly::crying::cyclops:

It's easy. Why don't you just flash your Firmware and your Kernel with Recovery again and install SuperSu again? Or you might try FlashFire by Chainfire

But what do you mean by Flashing and kernel with Recovery?:crying::silly: I mean I know about Flashing and all this recovery stuff. But please can you elaborate further on what you said ? I will be thankful to you

Well, you do almost exactly the same as in the guide, but you leave out the drm backup Part (not the restore part) and you dont use the firmware version in your guide, you use the newest one avaliable which you can download with xperifirm

Ahan .. Got it .... :good::silly: .. Did you try this method? Maybe the newer build might have some kind of security feature that this old guide will fail to address and thus ending up with NON-ROOTED Upgraded MarshMallow. I am optimistic about the return of Sony' STAMINA MODE. Thats why I want to upgrada ASAP because this current DOZE MODE of MM itself is sucker and doesnt deliver as it is advertised

I think what ali112 said makes sense, the only question I have is wouldn't we require an updated version of the kernel too?
This hasn't been updated yet: http://forum.xda-developers.com/xpe...-twrp3-0-z5-adv-stock-kernel-2016-03-t3333829
And from what I see, this one had a SIM detection error (haven't tried it myself): http://forum.xda-developers.com/xperia-z5/development/32-2-0-224-ftf-rootable-kernel-t3391071/page4

It's easy to upgrade, download the latest . ftf extract the kernel and prepair it as before, flash the new .ftf with flashtool without wiping any, then flash the new prepaired kernel with fastboot.
This worked for me
/MKL

Yes, MKL is right. Mantis is right. I havent read the whole guide, I thought it includes the extraction of the kernel and patching it. Alternatively you could use AndroPlus Kernel v31 or higher

Don't be too exciting for stamina mode. It is really bad... I mean it disables all animations....

Root?

Why it's almost impossible for us to have the root with the locked bootloader.? Since the day the mobile went out till now it wasn't possible ?, so is there a chance?

Nope highly unlikely, since dm-verity security was introduced on the z3+ all xperia devices after this require a unlocked bootloader for root. A modified system just won't boot up.

so after the searches, I did I found out the following:
1- first, since I'm on android 7.0 I need to downgrade to 6.0 in order to backup my TA ! wich I can do via Flashtool
2- I do the backup
3- I root the phone and restore the backup I did
4- I upgrade to android 7 and then I'm good to go!
my questions:
1-what will I lose after unlocking the bootloader? and if I restored the TA backup will that count as if i didn't unlock the bootloader?
2- how I will root the phone? with a custom kernel or is there any other way? and if with a kernel any advice?
3-shall I do the root before upgrading to android 7? or before? and will I be able to still get updates after the root? or i will have to do it through Flashing Ftf of the new updates?
4-anyone is running Xposed framework?
thanks so much in advance ))

im not sure what we lose after bootloader unlock.. From what i read on the androplus kernel thread, if you use androplus there is some amount of drm functionality restored. there is no clear consensus from what i have read, and being a ex-Z3 user im still paranoid about this as in Z3 without the DRM camera is basically ****.
no xposed for nougat yet - so that's out of question.

For every upgrade (via SONY's FTFs):
1. Flash FTF via Flashtool
2. flash suitable recovery and AndroPlus kernel (look in this forum and follow the instructions on AndroPlus' website)
3. boot into recovery, flash SuperSU and whatever you need
There should be a possibility to flash the devicekey (not the whole TA-partition!) to another partition to get the whole DRM-enchillada back. That does not work for me since it is not included in the FSC as of today.

Can I root xz without unlocking bootloader

Hi All.
I have an xz on oreo. My bootloader isnt unlockable so im wondering if theres a way to root the phone without having to flash twrp etc.
I see that oneclickroot say its unlockable but want 29$ which I think is a scam.
Any suggestions would be appreciated.
Cheers

No. It's literally impossible.
Any app saying otherwise is pure scam.

If you can download a MM firmware and flash that using flashtool you can root without unlocking the bootloader.

Yes, that is what I said. There was still a vulnaribility in the MM firmware (Dirtycow) so if you can find a FTF for MM, then you can flash that with flashtool and use the dirty cow exploit (Thread in general section) to root.

Hmm,,
Looking back I can only see threads about temporary root. I was positive you could root on marshmellow….maybe some more gooloing required

I have searched for it on Google and the results are only for those who have ubl yes, but is there really a way in this forum?

Yes, you can achieve temp root on marshmellow, that is how the TA backup tool work. I was pretty sure from there you could install arecoevry and flash a stock based rooted rom with a stock kernel. So its a system root not a kernel root, but this is going back a couple of years as since nougat this exploit was patched and only unlocked bootloader root was available.
But there the XZ can be downgraded to MM so its possible.

Oh, I've found it, maybe later I'll try it ... Thank you for the help bro ...

since xz came out on Android 6.01
so downgrade to ADROID 6.0
extract DRMKEYS ( TA.IMG)
UPGRADE TO ANDROID OREO
UNLOCK THE BOOTLOADER
ROOT IT
AND RELOCK THE BOOTLOADER AGAIN WITH TA.IMG
just give me the android version you wana stay and i will send u modded kernel, the one given in the post has universal drm fix! and if you relock your bootloader it will go in to bootloops!

If you relock the bootloader you cannot use a modded kernel. You have to keep the bootloader unlocked.

No, can only be done on 6

But I searched Google for backup TA but the conditions must be rooted, whereas I want to backup TA for root

Yes, on android 6 you can temporarily root to backup the TA, then you can revert back to any version of android and unlock the bootloader to flash a custom rooted kernel to gain root.
However, if you restore your TA it relocks the bootloader, meaning only a stock unrooted kernel will work.
So, use flashtool to flash a MM FTF and use the TA backup tool to backup your TA. Then just unlock your bootloader and use a custom rom.

Ohh now I understand, thank you for your explanation bro and I hope I managed to try it
