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.

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

how to downgrade and what is the unlock boot loader ?
and when i bought phone what is the default ? that boot loader is locked ?
You may be able to use the Panasonic Eluga software to downgrade to lp.
You must unlock the bootloader to install twrp and cm.
Some info here: http://forum.xda-developers.com/idol-3/development/tool-tools-idol-3-5-5-4-7-t3441781
When flashing anything to any phone, things can go wrong; therefore, I suggest that you familiarize yourself with flashing and be ready in case of disaster.

You can't flash twrp unless the bootloader is unlocked. The bootloader cannot be unlocked on MM, only LP.

Hi all!
I have my Xperia M2 with the latest firmware: 18.6.A.0.182.
I want to root it, and install a custom recovery, and i know how to do all of this through this forum. But I need to unloock my bootloader.
What's the problem?
If you go here: (i can not post links, the developer sony / unlockbootloader) and warns you:
Important note! In order to unlock your Xperia™ M2 you need to be on software version 18.3.C.0.37. Also beware that booting this device the first time after unlocking the boot loader may take a long time.

I don't know why this...
Searching in google, the people recomends to use flashtool to unlock the bootloader.
What will happen if i intend to unlock it and something goes wrong? I don't know how to solve a soft-brick withouth an unlocked bootloader.
Thanks for your help.
Hey, first do it the official sony way flashtools doesn't work for many including me when i unlocked my bootloader. http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Second if anything goes wrong, just reflash your firmware (jellybean, kitkat, lollipop whatever) through flashtools and it will be back to stock.
Unlocking your bootloader there is not much which can go wrong.
Btw, you will lose your DRM keys. 2 of them i think for buying stuff through ps store.
Also if you run into problems post here we'll help.
Now I have root with KingRoot. If I make a backup of TA partition i can restore DRM keys when I like it, no?
And the magic question for me is: How I flash original firmwares if the bootloader is locked? I only need locate the right FTF and with flashtool is enought?
Thank you!

Yes you can restore your DRM keys backup if you want in the future.
And if you want to flash a FTF on locked bootloader you can use Flashtool by Androxyde or Xperia Companion.
Ok, thank you all, I'll try to backup DRM keys and unlook the bootloader and I'll post the results!
Hi guys, so i just bought a Z5 Dual E6683 online yesterday and it turns out to be a Commercial/review model with 32.0.A.5.19 firmware installed, and I'm planning to root it to restore my Titanium Backup.
There're 3 things that I want to ask,
1. Is it possible to root it and upgrade to MM but with DRM still intact?
2. If so then do I need to flash another ftf 1st or change kernel or anything?
3. If I flash another Lollipop ftf, does it erase my current DRM or no?
Nah you have to unlock BL to get Z5 rooted. You can try the DRM backup tools though.
Patched kernel is enough just for root
If you flash official FTF you won't lose DRM(you only lose it by unlocking BL), however, I don't think it is possible to flash back to LP

You mean there's no going back to Lollipop once you patch the kernel and upgrade to MM?
But to patch the kernel I need to unlock BL right?
So, in conclusion I need to flash official LL ftf 1st (any build (?)), then backup DRM and unlock the BL, patch the kernel, and finally upgrade to MM?
And do I need to backup my current firmware (32.0.A.5.19) ?

You have to flash a Lollipop firm, then use this http://forum.xda-developers.com/crossdevice-dev/sony/iovyroot-temp-root-tool-t3349597 . Backup your DRM and then you are ready to open the bootloader, and flash a rom or root or do what you want.
You are on right firmware to root and proceed.
1. Is it possible to root it and upgrade to MM but with DRM still intact?
Ans. Yes, use this tool to back drm first from http://forum.xda-developers.com/crossdevice-dev/sony/iovyroot-temp-root-tool-t3349597 and then unlock bootloader and then download any MM firmware and flash. Then you need patched kernel to root your device from here http://forum.xda-developers.com/xpe...ot-automatic-repack-stock-kernel-dm-t3301605.
or I have already made for E6683 for the latest MM firmware here http://forum.xda-developers.com/xperia-z5/development/root-automatic-repack-stock-kernel-dm-t3301605
you can use as you wish.
2. If so then do I need to flash another ftf 1st or change kernel or anything?
Ans. as i said above.
3. If I flash another Lollipop ftf, does it erase my current DRM or no?
Ans. flashing doesn't erase anything but bootloader unlocking does. So answer is NO.
How do I update from a rooted nougat build 0.372 with patched kernel to the newest update 2.33? What are the manual steps I have to follow, thanks in advance
since bootloader is unlocked OTA may not come to you
you have to download the full rom by flashtool and then flash it in flashmode
some time back a user asking for singapore rom, i replied short tutorial for him
see this
https://forum.xda-developers.com/showpost.php?p=71394777&postcount=3
for him the device was z5p SATSUKI
but for you i should be z5 SUMIRE
Thanks for the quick reply. In fact, I DID get the OTA notification, but after downloading when i try to install, it reboots and then gives me an error msg saying that soemthing went wrong. I suppose this won't happen when I manually flash it with flashtool?
Just in case u have bandwidth problem or don't want to download 2.8 gig, u can relock your bl (make sure restore your special ta, dont restore some one else or facing hard break) after relock your phone won't boot up, its soft break,so just flash a previous ftf file and let it update,for later ftf it is about 187 mg, for older android N it may a little more but remember this method just work if u have an old Nougat, not for mm or older one.
After update just unlock bl again and flash the kernel if u want root,striped kernel of 32.3.a.2 are available in some thread just search.
Or just download the new ftf and flash
