Hi! I unlocked my Z3 without backupping, so I lost the drm keys. I know there is a way to fix it on the part of camera, sound, etc. But will the Sony upgrades come as normal?

Hi,

Pardon me for saying this, but it's never a good idea to unlock your phone without making a backup beforehand. AFAIK, Sony upgrades will not come to unlocked phones as normal, so I would advice you to make a backup now and reset the device to the factory settings. I know that's a pain in the ass and a hell of a job, but IMO this is the only way to "repair" your device. If this does not work for you, alas you have to reset your device entirely.

kindest regards. kuzibri

Will the drm keys come back that way?

Do not know for sure, but I know that resetting your device to factory settings, gives you back your original Z3, so probably also your drmkeys and your factory warranty, cause when you unllock your device, you loose the warranty anyway.

I'll be getting the Z3 in a couple of days. Some things I want to check because I've been away from Sony phones for a while(last one I had was an Xperia S).

So to root it is still recommended to downgrade to Kitkat and root using this method, as well as recovery? That procedure will not break my DRM keys(I remember unlocking bootloader caused that on my Xperia S). Afterwards I can just flash a .zip file and update to the latest 5.1 ROM?

One other thing; before I start tempering with my phone in any way, is it possible to back up DRM keys/EFS partition or whatever without root? Someone please link me some guide which will get me completely backed up. I know my DRM keys are safe until I unlock my bootloader(which I won't do) but I'd still like to back up while everything is stock, you never know.

Yes, that method will work.

As soon as you have root and a custom recovery, you can back up everything. With Backup TA, it's possible to back up and restore the DRM partition.

And now for my own question.

What's the deal with the Z3's kernel and recoveries? I'm on a rooted 5.1.1 without an unlocked bootloader, but with TWRP and CWM from XZDualRecovery.

Why do you need to unlock the device to flash a kernel? How is the kernel attached to the bootloader and why does XZDR work, even providing two recoveries? Is the main ROM image just modified so it will can load the recovery before Android itself and the recovery partition is intact? How are kernels and recoveries connected? I see all kernel threads mentioning included recoveries.

This is really weird, but I came from a Galaxy Nexus where the recovery partition was separate from the system partition and where flashing kernels was a normal thing. Kernels and recovery had absolutely nothing to do with each other.

I thought if you re-locked the bootloader you can use PC Companion or Sony Update Service to repair to stock. Not sure if it restores drm or camera stuff.
Hi,

In principle, you're right, but I also do not know for sure if everything will be working as it should before, especially the drm and/or camera.

Hi,

why do you want to unlock your new Z3, thereby loosing your warranty, to downgrade to Kitkat? I just would suggest to use Lolllipop for a while on your new Z3 before making that decision. I have Lollipop also, and although I had to get used to it, it's way far better that Kitkat. Just my 2 cents.

kindest regards, kuzibri

I am not going to unlock my bootloader at all. I'll only downgrade to kitkat so I can root the phone and install custom recovery, afterwards I'll flash stock LP. I don't think you can root LP without using Kingroot, which sends some info to chinese server which I do not want.

You can use kingroot safely.Many of us have used it and there is no longer an issue of malware or ads.

Big help required please

Mine wont charge beyond 1%.
I plug in the charger with phone off and the red notification light comes on followed by the Sony Xperia startup screen, after about 4 seconds the red light goes off and does not come on again. The screen then changes to an image of a large battery displaying 1%. When I press and hold the power button the device turns on as normal but given that the battery is only 1% it doesnt even last a minute. I have had it upto 12% at one point (not sure how as I didnt do anything differently) and the power drained that quickly when turned on it went down 1% about every 10 seconds.
Im on T-Mobile using a D6603 stock unmodified in any way. I have tried hold vol up and power button, hold vol down and also I have pressed the yellow button beside the sim card. I have had it on charge nearly 2 full days and Im now at breaking point. I appreciate I may be due an update but as you can see my phone says different. Pictures included

(This post is in another thread but wasnt getting much help, so reposted here)

Hi,

nasty problem. Guessing the charger is connected to a wall outlet:
1. Did you already tried a different/new USB cable, if not, please do so and see if the problem is solved?
2. Did you already tried to charge with the phone on?
3. If these things do not work, you probably have a battery issue and have to send it in for a new one.

good luck and kindest regards, kuzibri

Thanks for your reply

Yes it has been plugged into the wall, laptop and car charger both turned on and off.
I have tried the supplied charger and a number of others. I thought it was gonna be a case of sending it away. Thats not good given that the phone isnt even 6 months old. do you suppose its the battery itself? If so surely i could replace it myself?

Hi,

regarding this: "If so surely i could replace it myself", I strongly advice you NOT to do that cause you're voiding your warranty with opening up the device.Did you tried another USB Cable??
