So I heard that unlocking the bootloader would remove DRM keys. So my question is what are the limitations of a device without DRM keys?
The reason I am asking this is that Sony pretty much abandoned Australian Z5P and never updated it to 7.1.1 or any update apart from the first 7.0 update. So because of this I'm thinking of flashing this ROM. Also, this is the right TWRP for Z5P right? My Z5P is the E6853 version. I haven't root/flash any rom on android in a long time so decided to get back to it now that my Z5P warranty has expired!
you can always backup your ta partition first before unlocking bootloader or it will be gone forever. i want to try that rom too. searching for best ways to backup drm keys. I heard that if you lost your drm keys, phone will be much likely to have bugs and errors.

Hmmmm I heard loss functionality on camera and sony apps but apparently there's drm emulation or something like that in that ROM. I was thinking of backing up DRM keys too but it seem that it would have to downgrade to android 6.0 first, quite a hassle I guess it would be worth it. Still not sure where to find older firmware though.

Guys i know there is lot of ways to unlock it etc.
I need a way to unlock it, but with possible to RELOCK to get official updates for phone.
And how is possible to keep DRM keys (i know that trackID works without it) but somehow i want to keep if there is any way.
Thx mates
There is no way to keep DRM after you unlock the bootloader, even if you relock it and reflash firmware DRM apps will stop working forever.

I don't know if there is ANY way to keep it.
But contact Jinx13, maybe he could help you.
Unlocking officially with sony ericsson comes with disadvantages
Damaged DRM key, losing the ability to update with SEUS, bricking your phone doing the OTA update...
Using software called setool you can minimise all those risks.

He is the man, he and his customers said DRM and DRM stuff is intact afterwards.
But I used the official method anyways and don't regret it.
You can still recieve official updates, just flash with FlashTool.
And SoundHound is better than TrackID or use the new version of TrackID which doesn't care about DRM.

Same here.
If you relock you also can update via PCC/SEUS (maybe interesting for official ICS), so there's no reason for me neither.
And I still like TrackID (using market version) and who on earth cares about music like.

Also I can unlock your bootloader keeping DRM and also you can use OTA updates and pc companion with no problems
is there anyway we can do it ourselves whilst keeping drm, is this the test point method?
Hi folks,
after a couple of hours spent reading the forum gaining many valuable info from tutorials, etc. - one important question remains for me:
How do I do a full backup of my Xperia Pro before I start modding / rooting it? There is no stock recovery console, right?
I do not intend to unlock the bootloader as this seems to be not fully reversible (DRM keys get lost)...
If a full backup is impossible - what is the best backup option / compromise?
After that, I want to root and then remove bloatware. I'm still on GB 2.3.4, build 4.0.2.A.0.69. Will switch to stock ICS later, presumably next year.

There is no need to backup if you just wish to root as long as you ensure that everything is done properly and you don't end up messing up your software. That's a different story if you wish to change to a custom ROM though. What you want to do is back up important stuff like your messages and contacts. To do those, you can use any app found on the Android market. Titanium backup is a good option, though I don't use it myself. Files on your SD card will not be touched, so there's no need to worry on that count.

There are recoveries that work on locked bootloader. You can use them to backup everything on the NAND. Or like the person above me said you can use applications to backup specific things like Messages,etc.
Thanks!
I finally decided to upgrade to ICS before rooting and because this procedure involves flashtool, I found out that flashtool is able to restore kernel and system partition with locked boot loader.
Now, my phone is rooted and I finally was able to backup and clean it up with Titanium Backup which I already had a license for...
Another tool that I discovered: X-Parts! It allows to boot into CWM with boot loader still locked... https://play.google.com/store/apps/details?id=com.pvy.CWMinstaler&hl=de I know that it is not as fail proof as CWM installed via boot loader, but it is still better than nothing...
Hello there,
I have no Idea if this is the right place to ask.
I'm not a COMPLETE :angel: noob, i have the Z2 Succesfully Unlocked and Rooted, so i have used Flashtool before (But didn't Knew what DRM Keys were, so they're lost)
Sorry i'm not realy good with finding links n' stuff, aspecially that English isn't my native language i have some difficulty understanding some of the technical terms such as "dirtycow exploit"
I want to Root my Sony Z5P [E6853] [Android 7.1.1.] and i have trouble finding the Right Threads of Needed Software and Tutorials for :
1. How to Downgrade to what ROM via Flashtool so i can root the device to save The DRM Keys (Stock Rom links n'stuff)?
1.2. Heared there is a way to Unlock The Bootloader without losing the DRM Keys ("dirtycow exploit") What ever this is
2. How to Backup DRM Keys?
3. Unlock Bootloader (Done Before with the Z2, but it as been a while )
4. Custom Dual Recovery (TWRP)
6. Custom ROM (LinageOS Prefered) (i know how to flash a ROM, i just need the link for the latest Official or UNOfficial version )
if this is the wrong place for this kind of assingment, just move or delet it
No worries!

Hi! See the thread in the General section titled (7.1.1. FTF patched kernel, etc.). Follow those instructions exactly and you will have unlocked bootloader, and be rooted with custom recovery. Our phones no longer have warranty protection, so no worries about modifying now. The new kernel in that thread, along with other new kernels, have DRM Fix integrated in them, so you don't lose your DRM keys with them (or you do lose them, but the kernel tricks your system into thinking the keys are still intact. My phone still shows DRM keys intact though I've unlocked bootloader, rooted and with custom recovery. Everything works as it should. I did backup my DRM keys when I was on android 6.0.1, but you must return to the android version you were on when you backed up your keys if you want to restore the keys. I didn't want to do that, and with newer kernels no problem. If you're already on android 7.1.1., probably don't need to flash the FTF. Start at step #13, get unlock code from Sony Developers, and follow steps. Make sure to first install all necessary drivers on your Windows or Mac version and test before starting down the path. Check that thread out and enjoy your "new" enhanced phone!
Hi guys, I'm considering rooting my phone, however, since I'm new to the LG world, I'd like to ask if the process causes any missing features, like with Samsung (e-fuse blown up, Samsung Pay, Health etc. not working anymore) or Sony (DRM keys erased, some camera features disabled etc.).
Another related question: is it possible to 100% revert the rooting process, relocking the bootloader and flashing the stock firmware, with no evidence left of previous rooting?
Every rooting breaks safetynet etc, so you must be aware of that. Every app which detects root access will not work.
LG G7 after unlocking bootloader display information "Your device software can't be checked for corruption. Lock the bootloader. Press Power to pause boot." which continues boot after few socends.
I think it's possible to 100% revert rooting process. I didn't see any info with bootloader state in fastboot mode or something else. Just that screen at boot process which i think will vanish after relock bootloader.
If i'm wrong somewhere, then please correct me.
If u use magisk most apps will not detect root.
Magisk also makes safty-net pass
Pockemon/ingress and other games running on unitu wont start.
But you can say godbye to your drm Keys.
And xposed whill tigger all root detection.
But u can always revert by just flashing a unpatched Boot no nead to relock

Thanks, but regarding DRM keys, do we really have them in the LG G7, like for example in the Sony Xperia phones? With these phones, I know that if you lose your DRM keys, some features are disabled / limited (don't remember exactly which, something to do with the camera and display).
If we do have DRM keys in the LG G7, which features may be lost by deleting them? Is there a way to backup the keys before rooting?
none of the 4k options for photos and videos works for me, it has no effect, is there a solution for this?
I used to have a custom ROM, but put the ''original '' with flashtool and these options don't work for me
Sorry but i'm afraid your original DRM keys are gone (since you unlocked Bootloader without backing up DRM keys) but on the bright side, you can flash kernels that simulate DRM keys restoring all the features you need.
Since you unlocked your bootloader why not try and flash newer custom ROMS?

I have used Flashtool for the bootloader, I already tried ROMS, the only one I liked is MROM because it has the 4K function and is similar to the original (but my cell phone has performance and heating problems that I tried to return to the original) but no it fulfills all the functions
Thanks for the support
