I must admit that i didn't think about finding a way to backup the stock firmware before installing the customized noba version.
Noba seems to be ok so far, but it sucks that i don't have the option to go back to bone stock ever, because i couldn't find the firmware on xperifirm corresponding to the phone originally. (looking at the SI number on the box which is 1299-9003.)
I thought it would be listed there but i looked for it after changed the firmware on the phone (all stock, dont care for root/3rd party roms.)
By that time it was kinda late.
So,is it possible to go back to bone stock by fooling xperia companion to install specific firmware? Just curious.
Interested in that as well. Using Lineage OS 14.1 right now. Would like to return to stock experience.
Flash rom with flashtool and bl locked. This that easy

[Q] rooted>unlocked bootloader>installed Custom Rom> back to original rom>guarantee?
I bought the sony xperia Z a year ago. I didnot like the Sony version of android so I rooted the phone, unlocked the bootloader and installed AOKP and afterwards cyanogenmod. After one year I thought of moving back to sony's android version and installed it with sony flash tool. Now my Smartphone's bootloader is locked and it is not rooted.
Now I have speaker problem with my phone. I had the guarantee for 2 years, so I still have time. But will I still get the guarantee and get repaired for free.
Well the bootloader is relocked and its unroofed and has a pure stock firmware so it should be repairable. Just send it in and see where it goes.
All the best

Nope, your guarantee is broken.
Today I got my mobile back. They send back my mobile back. They said my guarantee is broken because I donot have original android ROM installed. I used the flashtool to install the original Android but they knew it, I did something with my mobile. :crying:

Well that's what you call bad luck, Anyway can you still retry to send it back? Or did the register all the devices sended to them.
First : Is your bootloader locked again? and did you fully unroot it instead of temp unroot?
Second : Is it the stock rom and not a rom that looks like a stock rom? Like a tweaked one.

First: yes bootloader is locked and the phone is unrooted.
Second: It is a stock ROM. I used the Flash tool from sony. I was even able to install the update from update manager from sony to android 4.3
Does the xperia Z have a flash counter? That could be what tipped them off.

Yeah you are right. May be there is the Flash counter, But I am not sure.
Hi! I've decided that I'm going to upgrade my rooted Z3 (D6603) to Lollipop. I currently have a locked bootloader and I'm running Android 4.4.4 (23.0.A.2.93) which I rooted using Giefroot.
Now if I follow this tutorial, I can upgrade without unlocking. However, I'd prefer Stock Xperia at 5.1.1 (since its built for my specific hardware) over Generic. The problem is, there's no US T-Mobile 5.1.1 build for the D6603. The closest two builds are 5.1.1 Generic and 5.0.2 T-Mobile UK. I'm torn between these two options, as I can't seem to find any good list of pros/cons concerning Xperia vs. Generic and 5.0 vs. 5.1.
However, there is a third option I am considering. If I were to unlock my bootloader I could run CM12, which would be much better than both Stock Xperia and Generic IMO. The only issue with that is that I'm confused as to what I would end up loosing. I've backed up my DRM keys, but I don't know what good any of that is going to do for me. I've also seen that I may be able to restore functionality using this, but I'm worried I'd screw everything up, since I fully grasp what I'm doing. I also don't know if I could turn back and re-lock if anything were to go wrong.
So my question is: Which firmware do I flash? And what will I end up having to lose? My three options are as follows:
CyanogenMod 12 (After Unlocking the Bootloader)
Generic, Unbranded Android 5.1.1
Branded (T-Mobile UK) Android 5.0.2
There are NO differences between branded and un-branded Sony stock software. you can flash the "generic" variant (please be sure to match you phone model... d6603 and so on)
you can also update you phone with a flashable zip made of:
a stock sony FTF
Xzdr recovery
Supersu package
To do this you need: PRF creator ; Xperifirm (to download FTF's) ; Flashtool (to make FTF's) ; Xzdr Recovery Flashable package ; Supersu Package.
My experience with CM12 is terrible because you won't get any benefit over stock software, because stock is the most optimized / featured Rom for Z3. with CM12 be prepared to forget the "power on and play"
the "this" mod is a package to restore the features (the magic behind the DRM keys of stock roms only when you have lost your DRM keys. this mod cannot be used on non-Sony based software. DRM keys are lost forever if you do not backup them before bootloader unlock.
Just to verify before I go on with this: I won't need a unlocked bootloader, correct? All the links for Xzdr Recovery I can find state that they will brick a locked bootloader.
Hi xda developers, I'm a new z3 user (D6633) running lollipop 5.1.1 , and I want to root my z3 to use titanium Backup,
1) I'm afraid that if I root my z3, I won't be able to update to marshmallow when it arrives, I also read somewhere that I still can update but will lose drm (I don't know what that is )
2) is there a way to unroot, to install the official update ?
Please explain in details and provide links if you could, cus I'm totally new on Sony
Any advice is appreciated
Im sure there will be a pre-rooted stock ROM for dl as soon after M. hits. Depends if one need to flash other things as well like firmware etc. but these things are included in the same FTF. I have gone through a few Android versions and things usually works out fine in a short matter of time.
If you absolutely want to go full stock, just flash a stock FTF from http://forum.xda-developers.com/z3/general/ftf-stock-firmwares-xperia-z3-models-t2886061
Using Flashtool.
I'm trying to downgrade my 920T to MM (DPG1 specifically) so I can install Darthstalker. I see a lot of responses that simply say you can't do it without any explanation. I've ODINed all the way back to EQC6, but it won't accept anything MM based. I even tried installing Darthstalker over EQC6 (some on that thread claimed it worked), but I get a bootloop. I see hints that it has something to do with the bootloader. Can I install an old bootloader before I load the MM ROM? I find it hard to believe that this can't be done.
You should be able to Odin back to firmware DPH2 as that uses the the same bootloader number 4 as nougat. The 5th digit from the right in the firmware version is the bootloader number. Hope this helps.
I'll give that a try
Any way to downgrade from Nougat to MM without losing FP Sensor,Haptic Feedack&Camera
I recently purchased a new S7 not realizing that it was equipped with a Nougat OS. I would like to restore my current phone to the new one, but my current phone runs on MarshMallow. After restoring the backup, my new phone has no haptic feedback, no fingerprint sensor with "an error has occurred with the fingerprint sensor. if this message appears repeatedly, restart your phone" message and the Camera doesn't work.
I'm sure it has something to do with bootloader N using MM. Even restoring Stock Marshmallow firmware (Including BL) on the new phone removes these functions. Does anyone have any ideas on how I can get these to operate?
My current phone has
Bootloader Version: G930W8OYA2APK3 (MM)
Baseband and PDA Version: G930W8OYA2API1 (MM)
When I restore my old phone to the new one, it ends up with
Bootloader Version: G930W8OYA2BQK4 (N)
Baseband and PDA Version: G930W8OYA2API1 (MM)
EDIT: Just tried the Nougat firmware with MM Bootloader. All of the functionality is present.
Bootloader Version: G930W8OYA2API1 (MM)
PDA Version: G930W8OYA2BQK4 (N)
Just restored old backup with MM bootloader (Boot, Data, System only).
No Fingerprint Sensor or Camera.
BTW, ignore the HAPTIC FEEDBACK portion of this post. I believe it is working.
Any help with this matter would be greatly appreciated.
Not possible to downgrade since the bootloader block you from flashing lower version of that. You may try to flash without BL, but your phone will be malfunction
Thank you for your reply. I don't think I'll be able to get the fingerprint wizard to work but having a functional camera would be a necessity. From the System/Priv-App folder I copied the SamsungCamera5 (from MM) and the SamsungCamera6 (from N) onto an SD Card. I guess I can try to play around with them to see if either will work, but I don't think they will since my restored backup should already have SamsungCamera5 and the SamsungCamera6 apk probably isn't compatible with MM. Kinda disappointing that I'll have to continue to use my old phone with a broken screen instead of the brand new one I purchased.

do not flash AP from a firmware set made prior to the bootloader youre on, it will more than malfunction, itll probably brick
i went back and read all the tl : dr stuff and saw that you seem to have got it working, oddly enough. The camera issue is likely the kernel
Thanks for the info on the thanks button. I've just about given up trying to get Marshmallow to work properly on this phone. Looks like it'll take weeks to configure my new Nougat phone to be similar to the three years of tweaks I've made to my old MM one. Oh well, first world problems I guess.
As others have pointed out, you can't use Odin to successfully flash a ROM with a bootloader that is earlier (in version) than the bootloader you have installed. The "gatekeeper" is Odin, however, not the bootloader.
Though I haven't tried it, it is my understanding that there is a way around this. Install TWRP, and use it to install a custom ROM which uses the version of bootloader that you want/need. Once the bootloader has been rolled back, you can use Odin to reinstall Nougat (or whatever). I don't know whether this might require a particular build of Odin, but I doubt it

i cant even begin to imagine how/why that would work. the bootloader doesnt really care what ROM you install, its the other way around. The ROM being installed has to be compatible with the bootloader. So, installing a ROM wouldnt really do anything to the bootloader and therefore wouldnt be able to bypass the lock in knox.
The procedure I outlined apparently works where the custom ROM includes a related bootloader. Thus, when it is installed via TWRP, it replaces both the existing ROM and the bootloader. I know that TWRP can be used to install a bootloader, as I have done it (on a SM-930F). And if the gatekeeper is Odin and not the bootloader itself, then this could work.
As I stated, I haven't tried this, nor have I extensively researched it. I've only read about it, and am passing it along as a possible solution.
This post can be closed since the phone was deemed Lost or Stolen by the carrier, therefore they couldn't unlock it for me to use my SIM card. I've since returned the phone. At least I learned a few lessons for my next one. Mainly, back up the phone when you first get it. Thanks again for all of the feedback.
