[Xperia Z2 Q&A, Help & Troubleshooting] KWOKSFUNG:
Guys i'm a Z1 user but i'm interested about camera quality after a Z2 unlock the bootloader.

Z1 have thread regarding to test the quality before and after.

For z1, after unlocking, the camera still works but photo it takes will have worse quality

could u guys have a try as well??

yea i know it works but does it really works perfectly??

i know u may not be able to backup TA here since u cant root before unlocking

but if someone intends to go for this one-way route, could u have a try??

if he camera still works PERFECTLY , maybe some awesome dev can port something to z1 so we can both have it!! (is my logic correct??)

thanks
[Xperia Z2 Q&A, Help & Troubleshooting] numskull:
Sorry, yeah im talking seriously. You're the one with the unlocked bootloader, therefore i assume you're rooted (if not, why did u unlock???), which means, you can see every file on your device. I also see you have access to the internet, google where the actual ta bit is n go see if you still have it. I aint been on these forums long but it seems to me that if you ask here loads of people will tell you that you lose drm/ta, as sony themselves.... you'll also get loads of people telling you the opposite citing the fact that things still work and that they have things with 'DRM' in the title as proof, you want a definitive answer..... check yourself.

As i said im not trying to be an ass, i cant tell you either way as i aint unlocked yet

By the way, the drm/ta folder is found in (i think, someone correct if im wrong). dev, block, platforms, by name, cant remember the full name of it but it ended something like mmc01TA

edit: after platforms, msm_sdcc.1, by name..... file is TA mmcblk0p1

From my experience if x-reality still works then Bionz will work. Photos on mine are very good after unlocking.

Anyone else?
[Xperia Z2 Q&A, Help & Troubleshooting] KWOKSFUNG:
thx for the info

Good for u if both of them work

but did u actually check the camera by taking photo in same location and lightning??

i heard that X-reality is enabled in sony 4.4 rom with unlocked BL

but for z1, photo quality is still decreased on 4.4 (while there's X-reality)

[MENTION=3783716]showlyshah[/MENTION] anything to do with this?? :p:p
[Xperia Z2 Q&A, Help & Troubleshooting] robt772000:
I have no proof of the camera being worse. My shots are really good though.
[Xperia Z2 Q&A, Help & Troubleshooting] biniek:
Hi, this is funy, because I have exactly same tumbprint, and I'm still on stock untouched firmware.

And I wont to have TA backup before rooting to maintain warranty.

What is lost when you unlock the boot loader?

Lag, bloatware, ads and boredom.
[Xperia Z2 Q&A, Help & Troubleshooting] Envious_Data:
Nothing besides your DRM keys at least to my experiance

And also unlocking your bootloader voids your warrenty
[Xperia Z2 Q&A, Help & Troubleshooting] biniek:
Is there any ETA for exploit allowing backup of DRM keys before unlocking bootloader? Is anyone working on this?
[Xperia Z2 Q&A, Help & Troubleshooting] Jackos:
Never ask for ETA.
[Xperia Z2 Q&A, Help & Troubleshooting] Envious_Data:
Yes that is something because big things like this are dependant on results

Have no idea, im trying to figure out sonys signature key nonsense
[Xperia Z2 Q&A, Help & Troubleshooting] critizen:
At this point (July 22, 2014), there is a root exploit available for locked bootloaders, so you can safely:

root your phone,

use DevShaft's Backup TA tool to back up your DRM keys/TA partition,

then unlock the bootloader.

Which means that you can restore the TA partition at any point in the future, and restore the DRM keys/etc. (Please correct me if I'm mistaken.)
[Xperia Z2 Q&A, Help & Troubleshooting] chentz78:
Just an information. For those who bought your device in a EU country the warranty still valid after unlock bootloader. You can see the explanation with base on EU declaration 1999/44/CE here :

http://piana.eu/root
[Xperia Z2 Q&A, Help & Troubleshooting] FakeSmile:
Well i read that If you unlock your bootloader on 4.x.x you wont lose DRM keys
[Xperia Z2 Q&A, Help & Troubleshooting] KuroTheBang:
If you install a recovery (throgh LockedDualRecovery) and then flash a new rom, will it be count as unlock? or still locked?

Is there a way to see if the device is still locked/DRM partition still there? like Samsung flash counter 0, HTC ***LOCKED*** etc.
[Xperia Z2 Q&A, Help & Troubleshooting] A|ex:
yes you are right you still have warranty however you are still open to possible charges for example if rooting is found to have caused the issues with your phone. Also any service centre has the right to charge, you must accept their T&C for repair, this involves these costs, loss of data etc.

Sony CS centre are not as nice as Samsung when it comes to rooting or voided warranty flags etc.
[Xperia Z2 Q&A, Help & Troubleshooting] KuroTheBang:
Then you've never had a case in germany :D

Here Sony is quite nice, and Samsung is like "Your device has a manufacturing bug? sorry bro, your device is rooted. that caused it"

I remember in the time of Arc S, where I've destroyed the battery chip (0% bug), and they changed it w/o problems through my warranty.
[Xperia Z2 Q&A, Help & Troubleshooting] A|ex:
maybe depends what CS you go to, in hong kong I have had 0 tolerance to this, in the uk sony were a different. now when buying a sony if I root I treat it as an instant loss of warranty, however compared to Samsung I know I am safe.

it might have something to do with the bootloader and loss of drm, you do not lose anything with the Samsung that will reduce apps from working.
[Xperia Z2 Q&A, Help & Troubleshooting] KuroTheBang:
I guess you missunderstood my post with that Arc S, it was just to show that Sony indeed changes their device even if they are rooted.

Well, Idk how Sony is now after they've broken up with Ericsson, I hope that I've never have to send my phone to repair.

Also, I don't know the law in HK, but in Germany they HAVE per law to prove within the first 6 month that YOU caused that missfuncion. So it doesn't matter if it's rooted or not. So basicly here in Germany after 1 year(or 6 months with root etc) it's like russian roulette.

Well, my device is rooted with custom FW, but it says "Bootloader unlock allowed: Yes" so it should be still locked with DRM partition and my warranty there :D
[Xperia Z2 Q&A, Help & Troubleshooting] Technowhiteboi:
so OTA is broken? :rolleyes:
[Xperia Z2 Q&A, Help & Troubleshooting] xerwudjohn:
to tell you the truth i unlock the bootloader of my z2 and my x-reality stops. i am very sure my X-REALITY STOPPED. because i took a screenshot with x-reality and x-reality off. then i didnt see any difference. sorry guys if you loss your DRM keys just because of unlocking your phone. hope you will TA Backup first before unlocking it, so that your keys will be preserve. anyway there is another way to relock your bootloader BUT to recover your DRM Keys? its not possible tho.
[Xperia Z2 Q&A, Help & Troubleshooting] Envious_Data:
its imposible to recover lost DRM keys, they are unique to each individual unit

Relocking the bootloader has always been posible though

Ota should be broken

~never saw this post lol, sorry for no reply
[Xperia Z2 Q&A, Help & Troubleshooting] xerwudjohn:
no it did not broke your OTA as long as you will relock the bootloader of your z2. but your x-reality will be disable permanently. thats why soon when i buy z4 or z5 i will never unlock the bootloader again. :D
[Xperia Z2 Q&A, Help & Troubleshooting] sa3d12:
but if u have backed up ur TA (DRM keys) and restore them after u re-lock bootloader... i guess this will bring back X-Reality functionality

am i right??
[Xperia Z2 Q&A, Help & Troubleshooting] fuzzedshadow:
Forgive me if I'm wrong but has anyone else noticed that the noise cancelling headset is far less effective at blocking out background noise after losing DRM keys?
[Xperia Z2 Q&A, Help & Troubleshooting] A|ex:
http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/

"Certain pre-loaded content on your device may also be inaccessible due to the removal of DRM security keys. For high-end devices running recent software versions, for instance Xperia Z3, the removal of DRM security keys may affect advanced camera functionality. For example, noise reduction algorithms might be removed, and performance when taking photos in low-light conditions might be affected. The secure user data partition may also become inaccessible, and you will not be able to get any more official software upgrades if you unlock the boot loader."

The example is the Z3 but there have been reports of this on the Z2, the noise reduction etc is interesting.

I lose "Video Unlimited" (maybe), someone happens the same or only me?

sorry for my bad english
[Xperia Z2 Q&A, Help & Troubleshooting] numskull:
Nope video unlimited should be fine, mine still works and my bootloaders been unlocked since april........ and whoever asked above, i cant say ive noticed any difference in nc, i still barely hear a double decker bus drive past when im cycling lol
[Xperia Z2 Q&A, Help & Troubleshooting] freekzak:
what about other camera apps ?

I unlocked relocked boot loader... now I am with "official" 4.4.4 kitkat via PC Companion (just to try it but tomorrow I will install again Carbon or another custom ROM) ...

The quality on my Z2 when I take pictures is not the same... not bad BUT NOT THE SAME , so X Reality is gone :(

What about other apps from the market ? Is there a camera app that can help with this "problem" , I mean to increase in a way the quality for pictures especially when I zoom ? Anyone who noticed a difference ? Please someone with screenshots ;)
[Xperia Z2 Q&A, Help & Troubleshooting] HellRoot:
For me it was the algorithms that had gone when unlocking my z1 and the Bravia engine still working... Your pictures will not be the same in my opinion when unlocking
[Xperia Z2 Q&A, Help & Troubleshooting] BlackArtsInc:
So,in a few words,unlocking your bootloader of an Xperia Z1 Compact will make you lose your DRM keys forever even if you restore TA Partition.

What will this lead us to no one seems to be able to answer exactly though. Lots of conflicting info on this thread. Im not sure what right or wrong.

It seems that the sure thing is that you wont be able to restore your phone to its original state if you re lock the bootloader..right?
[Xperia Z2 Q&A, Help & Troubleshooting] Agares69:
Not sure if anything has changed since then, but my bootloader is locked and I don't have the following line: com.sonymobile.drm.ui

So what's the situation now? Sorry for reviving the post. :P
[Xperia Z2 Q&A, Help & Troubleshooting] foten21:
i bought a used z2

now bootloader is locked

how i know bootloader never unlocked

or was unlocked and then relocked

so i lost the extra features of the locked bootloader(camera etc)

or not ?
[Xperia Z2 Q&A, Help & Troubleshooting] :
Compare with another Sony phone with X-reality, it will NOT work without DRM Keys, or try to send an MMS with your location. If it says "service unavailable" or other message meaning the phone couldn't locate you; you have no DRM Keys.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Gambinohe:
I tried to factory format my phone through TWRP, then when I tried to restart again, it never comes back.

I still have access to TWRP, but when I install zip files I downloaded, it always failed. I tried to use Odin, it failed to flash an image in.

Plz help me.

Many thanks.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Larry2999:
What format option did you select in TWRP and hope you didn't accidently remove your OS? The device could fail to boot if you don't have an OS installed. You may be able to flash a complete stock restore image via TWRP. Would you recall what Android version you were on before the brick? Also what is your phone model and carrier?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Gambinohe:
Mine was ATT S3 I747 with Android 4.3 system. I did wipe my OS during recovery. That caused the whole problem. Then I use TWRP to flash a system and a kernel in. I was unable to flash bootloader and modem in; I did not know what is the problem. The weird thing is that I successfully start my phone and used it for a while. When I rebooted it, it dies again. I tried to install the some boot update in this January. It never works again. Any advise?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Larry2999:
You can try flashing a complete stock system to get your phone back to working condition. Since you already had 4.3, flashing zips often fails if there is a bootloader incompatibility. The stock restore should do it. Please go to the following thread ....

http://xdaforums.com/showthread.php?t=2658486

Download the stock restore zip to your PC. Use another device or something to load it to a (micro) SD card. Insert the card into your phone. Boot into recovery mode and flash from TWRP. When done, wipe your cache/dalvik and reboot to system. Let's know if this works for you.
[Verizon HTC One (M8)] Deathbynukes:
I've been on stock as well as venom rom and insertcoin, but none of them seem to be able to send or receive MMS without mobile data being on. Any ideas?
[Verizon HTC One (M8)] andybones:
I believe this is a Verizon thing.

4G *should* kick on automatically when recieving an MMS message.

If you watch closely when one is coming in and you have wifi on you can see the 4g icon appear as the MMS finally comes threw.

I am not sure why they choose do to this to us, but I don't believe there is a way to make it work over wifi (that I am aware of anyway)
[Verizon HTC One (M8)] Deathbynukes:
Ah okay. I'm wondering if there would be a way to momentarily switch data on to send or receive MMS. Keeping mobile data on all the time seems like a waste
[Verizon HTC One (M8)] andybones:
For me personally, on my ROM, the 4g will kick on automatically if you are sending/receiving an MMS message so you don't have to keep mobile data on
[Verizon HTC One (M8)] orangekid:
That's so strange.

Does it do this on AOSP ROMs too, and other VZW phones?
[Verizon HTC One (M8)] Deathbynukes:
Awesome, I might give bonestock a try then. Is that something you had to implement in your rom, or should that be an included feature on stock?

It happened to me when I had my s3 on Verizon as well (running aosp)
[Verizon HTC One (M8)] andybones:
Nothing I did AFAIK. I did try out cm11 today and had to manually turn on 4g so perhaps its an aosp thing?
[Verizon HTC One (M8)] Deathbynukes:
Maybe, but I'm running a sense rom and it still has that problem :/
[Verizon HTC One (M8)] Napoleones:
This is on what ROM? I want this too. I don't want my mobile data always on.

well you have to be rooted and unlocked before you can get soff. if you're already good there sometimes firewater has a problem with the hardware regardless of version date... if you already unlocked and got root try doing it again then trying firewater oncemore. if that doesnt work you might want to try to get a different device from sprint/assurion

[Sprint HTC One (M8)] koolcat7:
Ive found out this...

The HTC M8's are made in different "batches". Each batch of phones they produce will generally have all the same internal parts, from the same parts manufacturer. SOME batches of phones have internal board parts that came from a DIFFERENT parts manufacturer, because HTC ran out of the last run of parts from previous manufacturer. In other words, HTC may produce phones with exactly the same parts, but the parts may come from different manufacturers. So, certain parts from certain manufacturers make it not s-off-able.

This is my understanding, correct me if you think I'm wrong, or you know something I don't.

I'm going to exchange mine and better luck with the 2nd, hopefully it will come from a "good batch" ;)

[Samsung Galaxy Nexus] boathead:
the phone is a sprint gnex.

i had twrp as recovery, and i was playing around with it, got distracted, and my 2 year old grabbed it and wiped everything. no OS, no recovery, no nothing.

i'm not even sure where to start. my newbie self is thinking maybe odin? i used adb once, is that where i should be looking?

i guess my question is where does one start when he has no OS. and i could sure use a link for wherever factory images, or tar files, or whatever, are reposed.

please help a brother out, and keep in mind i am in fact over my head. just trying to salvage this if possible. it is not an urgent thing, as i the device is merely used as a media device for my 2 year old.

my laptop is a windows 7 device. i've downloaded usb drivers for samsung, odin, and adb fastboot. they are sitting in my download folder as zip files. that is where i stand.
[Samsung Galaxy Nexus] ashclepdia:
Don't worry you'll be fine.

If you can get into twrp, try just downloading a ROM and gapps zip on computer and using adb to push or sideload to device (Google "adb sideload ROM galaxy nexus...exact steps easy to find)

If you can't get into recovery, or just want to go back to complete stock and start from there, go here https://developers.google.com/android/nexus/images

Grab a package for sprint gnex(mysidspr, aka toroplus) and if u have adb&fastboot installed on computer(if not then Google "installing android SDK" and it will be top result, fastboot and adb come WITH the SDK when u install it)

Then you just unzip that factory img file, plug device into computer while in boot loader mode (hold power and both volume keys), open the folder created when u uncompressed factory IMG file, hold down shift and right click and choose "open command prompt". Enter "fastboot devices"(no quotes) in the command window to make sure device is recognized. Then just run "flash-all.exe" or "flash-all.bat" in command prompt and BE PATIENT AND LET IT FINISH EVERYTHING. After that device will be like brand new out of box.
[Samsung Galaxy Nexus] boathead:
thank you so much for responding. i will play around with this later, but it is a bit comforting to know that maybe i'm not doomed.

i cannot get into recovery, so yeah, i don't know what i'm doing.:(
[Samsung Galaxy Nexus] ashclepdia:
Why can't you get into recovery?

Are you choosing recovery mode via the bootloader menu? I didn't think it was POSSIBLE to wipe recovery from within recovery.

Even if you can't, trust me, Doing a factory img restore, or using fastboot to flash custom recovery again is VERY easy. To get the SDK that has needed fastboot tools, go here http://developer.android.com/sdk/index.html#ExistingIDE

And grab the needed exe for your setup(windows 64 or 32bit). Make sure you are getting the "ADT bundle" it's what has needed platform tools. Then just run the exe and follow instructions.

Now u COULD also just Google search for Wugfresg toolkit, and download and use that. Its very easy to use as well. I just prefer to have adb and fastboot installed to my computer so that I can always be good to go. Plus I use Linux so Im not able to use Wugfresh, but knowing how to just use fastboot and adb also makes ya feel like a boss(even though is pretty simple lol)

Don't worry, there is hope, and it's not gonna be difficult. You'll be up again in no time.
[Samsung Galaxy Nexus] boathead:
because you said you didn't think it was possible to wipe recovery from recovery, i went into bootloader. you are correct. in my panic i overlooked it. i DO in fact still have twrp.

but there is nothing to restore or install. so once my phone charges, i'll give it a shot as you suggested. would you kindly check in later in case i need some more help?

thanks my friend for steering me in the correct direction.
[Samsung Galaxy Nexus] ashclepdia:
Of course!

I'm always checking in these forums, and I use Tapatalk, and have actually grown fond of Tapatalk notifications, so I SHOULD get a notif if you post back or PM(though I prefer to keep in thread, that way someone else searching for answer to similar issue can find a helpful thread as well)

Yea it sounds like your little one got into twrp and most likely wiped all of /data and /system. Instead of just a regular factory reset which would have left your stuff like flashable zips and all still in /sdcard. That sucks! I've actually done that on accideHahaha

hile back(a mistake you only make once to wipe all of /data AND /system lol, even though can pretty easily be fixed)

Sounds like you could use adb sideload or push to get ROM/gapps zips back on the device, or just go with a total device factory restore, whichever you choose at this point should work just fine.

I'm not sure if there is a way to do this yet, but I've always wanted to put a pin code lock for TWRP. That way if my nephew ever did find his way into there when using my phone, he wouldn't be able to do any damage. If it's not a part of custom recovery yet (I haven't looked actually lol) it would be awesome if someone found a way to add that feature in. Could save a lot of us the hassle in cases like this! Hahaha

I'll check back in the morning and randomly tomorrow (some of the day I won't have a connection, I use Gnex strictly on WiFi) to see if you need any help/tips/clarifying of any steps needed. Once you do this restore process once, you'll be amazed at how easy it can be, and as long as you keep the files on your laptop, you'll be ready to go if you ever need to do it again. :)
