Please explain to my phone that it should have been fully working (x-reality, bionz) even with unlocked bootloader as it clearly wasn't. I will not argue with you, I was forced to restore functionality as previous owner unlocked bootloader without doing backup of TA partition and more users might do this following your advice. It is completely ok that you do not miss x-reality or that you are ok with high noise in photos, but many users are not satisfied with this (myself included). Once they follow your fast and easy way of root, they will spend more time to restore the lost functionality. But to each his own I guess.. :)

Btw. did you even bother checking photos I posted? How can you say that ONLY x-reality was disabled by DRM keys removal?
[Xperia Z2 General] ravdo:
Not sure if it's true or not, but someone posted that the PS4 remote play also doesn't work with unlocked bootloader.
[Xperia Z2 General] _mysiak_:
Yes, it seems that playstation stuff is lost as well.

The proper way is:

1.downgrade (flashtool) to anything older than .167 without unlocking the bootloader

2.use towelroot and install recovery

3.backup TA partition (in case you plan to unlock bootloader)

4.flash pre-rooted .167 via CWM recovery

5.flash in flashtool everything in .167 ftf file except system partition

5.5 optional - clear data(if you're worried about corrupted data by downgrade)

6.enjoy rooted phone with ALL functions and full warranty

It takes around 20 minutes once you have necessary files downloaded. You are free to unlock bootloader if you wish (no point if on stock rom) as you can restore TA partition anytime.
[Xperia Z2 General] funky0308:
Not only expert users...everyone knows for this method.

It's few years old system...nothing new...

It's quite simple...if you can unlock or want to unlock bootloader you can root every fw, even 5.0 (tested on N7 2012).

As long as you can flash custom kernel you can root your device, that's something brids already know...
[Xperia Z2 General] chesterr:
Don't ever try this method, TA needs to be backed up, if you don't care about any of those features then go ahead unlock your device.

Otherwise please we have a way to root the device, plus I have downgraded my phone multiple times., I never came across any of these problems. If you're really unlucky and rare cases like 0.1% will have the problems when downgrading. So far Sony phones are safe and okay to downgrade. I've done it multiple times.
[Xperia Z2 General] weltwon:
Newbies

You know it, I know it, BRIDS may know it, a zillion other Droid users may know it but lots of NEWBIES don't know it.

Unfortunately, lots of newbies hear "ROOT ROOT ROOT" and want to get there as fast as possible as if there's a pot of gold waiting for them!

May not be a pot of gold but Wireless Tether for Root Users, being able to run Quick Boot app and quickly go to CWM so I can make a full nandroid backup and a list of other apps is why I sought and found the fastest & easiest way to achieve root while on 23.0.1.A.0.167 firmware.

Yes, I want BEST possible images with the 20 megapixel camera in my Z2,

so I will be working on easiest way to restore X-reality OR I will find a BETTER camera app!

Glenn ;)
[Xperia Z2 General] _mysiak_:
Good luck with unlocked boodloader, no backup of TA and not willing to do the FW downgrade :) So you basically saved 5 minutes for rooting and now going to spend few hours to restore what you f***d up (and will never really acomplish) and encouraging newbies to do the same.. Great idea :D
[Xperia Z2 General] ghostofcain:
For comparison photos to be of use they need to be identical these aren't, second photo is zoomed in?
[Xperia Z2 General] _mysiak_:
There is probably some misunderstanding. Photos demonstrate the change of quality of camera, NOT x-reality engine. Both were taken handheld before and after the change few minutes apart with no further modifications. This is why they are not identical in composition.
[Xperia Z2 General] ghostofcain:
There are threads with people who know a lot more about photos than I do, where people have decided there is no degradation in photo quality after unlocking bootloader. In my personal experience I can't see any difference in my photos taken before and after unlocking so that is good enough for me.
[Xperia Z2 General] _mysiak_:
Just take a look on the pictures. If you do not see the difference or do not care about the noise, be happy with what you have. For me (and other people who restored bionz) the quality increase is big enough to spend extra time to restore the functions lost by unlocking. Personally I do not care if experienced user unlock their bootloader, just don't like that newbies are instructed to do so with no proper warning and no backup of TA. Mainly as we have safe rooting methods out there.

Btw, I've seen that some people decided that x-reality is not lost with unlocked bootloader, but my experience is different. Same applies to camera performance.
[Xperia Z2 General] kamalmawa:
Sony said this before we received our firmware to latest build 23.

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.

So if I were you, I would backup TA using backup-TA before doing such a risky process. I have done this unlock and relock bootloader process to root when I had my old xperia Z. Only because we had no other option to keep the root and dry keys ;)
[Xperia Z2 General] funky0308:
That's even worse...

You are telling users, who (probably) aren't aware of TA backup and warranty lost, to unlock bootloader?!

We are downgrading fw to root it and to backup TA partition.

Then it's safe to unlock bootloader.

Name your thread like it should be from the beginning and please, inform users in OP that this could void their warranty.

Title is really misleading, I thought someone found a way to root latest Z2 fw on LB and UB and that's not it...I'm sure I'm not the only one.

Even we cannot be held responsible for broken devices, we should try to help and to inform users before they try something serious like this.
[Xperia Z2 General] weltwon:
Please READ Post #1

Did you READ post #1? I already have MULTIPLE warnings in bold RED letters.

My thread title is an EXACT description of my rooting method.

For the record, ANY rooting method for any Android device has always carried risks, especially for newbies a/k/a NOOBS.

If someone misses 1 step or does it incorrectly, it can brick a phone.

That's one reason why a method with less steps may be better, especially for novices.

Glenn ;)
[Xperia Z2 General] B1nny:
Yes you 'warned' people, what is also written in italic RED letters is the following:

Which is not true! When unlocking your bootloader via the Sony website you're wiping the TA partition, which is where these DRM keys are stored. In your guide you never tell people to make a backup of said partition and thus they cannot restore X-reality and/or Bionz. (of which I'm not even 100% sure that it's lost in the first place but okay) The only way to 'restore' these features is by flashing a bunch of patched files that remove the DRM checks in the Sony applications and libraries, which is device and firmware specific.

The reason obtaining root without unlocking your bootloader is because we don't want to lose this TA partition, so we can restore it later to fully regain access to everything that was revoked by unlocking the bootloader. Because you can only root your Z2 on a lower firmware without unlocking your bootloader knowledgable people recommend users to downgrade, backup their TA partition and then unlock their bootloader via the official Sony website.

Since everyone who wants to root their Z2 and/or wants to unlock the bootloader will at some point come in contact with Flashtool it's sensible to teach people how to use it when they start, not after they have 'messed up' their phone. (because that's bound to happen at some point)

I highly recommend you to remove your statement that X-reality and Bionz can be restored, because they can't and properly explain people what they will be losing when using your guide to root their devices.
[Xperia Z2 General] Plogm:
the solution was GREATTTT , solved my worst nightmare (the touch screen issue on z2)

thanks to all of guys who coded this recovery
[Xperia Z2 General] kamalmawa:
Relocking your bootloader using flashtool is easy, but your DRM keys will be lost forever. So please add the proper way to backup your TA before unlocking it at the beginning of your guide because newbie's will loose along with their warranty :)
[Xperia Z2 General] Envious_Data:
+1

Exactly my point.

You can unbrick a Locked devicr much easier than a unlocked device

Also less risks overall, Both regional and international warrenties are void

X-Reality is not restorable with a unlocked bootloader, there are mods that will only work on certain devices and its not all to common those certain devices
[Xperia Z2 General] _mysiak_:
[MENTION=2790386]weltwon[/MENTION] - the main problem which everyone has with your topic is, that there is missing backup of TA in the steps. Relocking bootloader without TA doesn't bring you anything back. Your warranty is still void, your DRM keys are still lost (service center will see this in service menu). Only some of the fuctions can be restored (x-reality, bionz) by closely following specific restoration steps and it seems that it doesn't work for everyone. As already stated, "your" method is well known for years, but as it doesn't bring any advantage over well known rooting methods with locked bootloader, it is not recommended to anyone. You are free to do what you want with your phone, but it's really irresponsible to encourage newbies to unlock their bootloader with no real benefit to them.

I even doubt that this method is faster&easier compared to the downgrade method as bootloader unlocking are additional steps which add complexity and time required. Not mentioning what you have to do to partially restore some of the removed functions.

Your warning is vague as you are saying that these things MAY happen, while in fact they WILL.

Removed the flaming, if you have issues with eachother, take it to pm and not here!
[Xperia Z2 General] weltwon:
Thank you!

I appreciate that MOD removed the bullying posts.

I agree with _mysiak_ post above, I CAN do whatever I want with my phone,

and everyone reading this CAN control their phones.

After using my rooting method,

EVERYTHING I need, want and expect from my Xperia Z2 is working PERFECTLY!

All my apps (Play Store & those requiring root) are working perfectly,

camera takes FANTASTIC pics. Unfortunately, my Z2 still can't wash my car. ;)

This smartphone is awesome and superior to my prior Galaxy Note 3 and

Sharp Aquos Crystal in MANY ways!

Thank you all for your input,

Glenn ;)
[Xperia Z2 General] GoldPunch:
It worked! Thanks a lot.

X-Reality-Super vivid and camera algortihm problem is solved. But still noise cancelling is not working.
[Xperia Z2 General] weltwon:
DRM Fix restores X-Reality, Bionz and Noise-Canceling

Using the DRM Fix created by jimRnor should not have any different results on your Z2 because it is designed to do just that, restore functions controlled by DRM keys.

However, I will investigate further and do more testing on my Z2. If I find ANYTHING relevant, I will post in OP.

I'm glad my ROOT method worked on your Z2 so you can use your Z2 to take FANTASTIC photos.

Camera in the Xperia Z2 is superior to all other iPhone and Android devices I've owned and tested.

Thanks (click of your THANKS button) are always appreciated and all I ask for.

If you want to make any donations, give it to the people who created the tools I used.

[Xperia Z2 General] Haldi4803:
So does that bring back MY DRM keys or just someone's?
[Xperia Z2 General] weltwon:
DRM Keys

DRM Fix page says, "MOD WONT RECOVER THE DRM KEYS THAT YOU LOST AFTER UB,

THIS MOD IS RESTORING THE FEATURES THAT LOSS BY UNLOCKING THE BOOTLOADER!"

I can attest that DRM fix works on Z2 Model 6503!

Glenn ;)
[Xperia Z2 General] Haldi4803:
so shouldn't you mention that on the first page? That DRM keys are unrecoverably lost? When reading 8. Install DRM fix it makes me think this will fix my DRM keys.... or ist it just me ?
[Xperia Z2 General] kamalmawa:
yes you will loose your DRM keys & warranty forever if you didn't backup using TA-Backup.. We have used this method to Root and push SU binary to system partition before NUT created his dual recovery for locked bootloader Xperia Z. Proper guide to use this method from Xperia Z forum posted here : http://xdaforums.com/xperia-z/orig-development/tutorial-upgrade-stock-434-to-253-drm-t2287149

But you need to flash RIC killer script with latest Sony firmwares. Re-locking boot-loader using Flashtool only gives you access to use official firmware updates such as Sony PC companion and it will not restore your DRM keys.
[Xperia Z2 General] weltwon:
DRM Keys / warranty / insurance

The issue about DRM keys and warranty has been repeatedly posted on this thread and I have it at the TOP of OP post #1.

Personally, I have ZERO need for DRM keys.

My goal was to create the FASTEST & EASIEST way to root my Z2 while retaining all the great features.

I plan to keep my Z2 for at least a year so the warranty is meaningless to me.

If physically damage my phone, Sony would give me a new one even if I had the warranty.

However, if my service provider offered Replacement Insurance,

that is something I would purchase and it WOULD cover replacing my Z2 regardless of DRM keys status.

Making it easier to try new updates from SONY is meaningful to me and unlocked bootloader makes that possible.

I accomplished ALL these goal with my rooting method.

Glenn ;)

I have rooted & unlocked bootloaders on MANY devices including the HTC MyTouch 3G, Google Nexus One, Galaxy S2, NOT S3, S4, Note 3, Tab 7, Tab 8.9, Tab 10.1, Asus TF700T, Acer A500, Nexus 7 tablet .... not ONCE have I had ANY problem reselling ANY of these devices for the highest going prices on eBay BECAUSE, I keep them in MINT condition with screen protectors, padded cases and save ALL the original packaging. Come on trolls, you're getting REALLY petty (referring to post #41) !
[Xperia Z2 General] ghostofcain:
This is disingenuous, at best, Galaxy S3 didn't have locked bootloader.
[Xperia Z2 General] faded_giant:
Ignore the haters.

Thanks for the tutorial Weltwon. This works well for me. I cant tell if Bionz or X-Reality are working but it doesn't appear different than before so its bot really an issue for me.

A little advice: I would like to see a little more info in the flashtool instructions. I have only used it once before and didn't know what to press after the lightning bolt icon. Other than that, really easy guide. Thanks!!

A bit off topic, after updating my Tap to Wake function no longer works. The setting is enabled and I've tried toggling it with various restarts with no fix. Has anyone seen this before or does anyone have any ideas? Thanks in advance!
[Xperia Z2 General] enrique71:
Odd, I followed the procedure and everything worked fine for a few days. Today, I turned on my phone and X-Reality is flipped to 'OFF', I enabled X-Reality and performed a reset then to my surprise the setting was flipped back to 'OFF' when it booted.

Not sure how this happened, but it did.

[HTC Sensation] maciek90:
Hi. I have problem with GPS on my Sensation XE. I've already installed CM11, CM12, PA, SlimKat but with no luck. GPS works only on ViperS ROM.

I've also tried wiping EFS partition, copying gps libs from ViperS rom and none of this has worked.

When I launch GPS Nmea Tool I can see nmea data strings on ViperS rom, on other roms there is no nmea data.

Does anyone know solution for this or has idea how to fix it?

Attachment contains logcat for SlimKat and ViperS rom while trying to get GPS signal.
[HTC Sensation] maciek90:
I wrongly assumed that GPS works on ViperS because only on this ROM I could get any response from GPS.

Today I switched back to this ROM and left phone searching for GPS signal for about 15 minutes and it couldn't find even 1 satellite.

After some searching I found this video. In 2:55 you can see black wire connected to board. I don't have it in my Sensation.

Can someone confirm if this is GPS antenna connector? Or simply disconnect it and check GPS signal?
[HTC Sensation] Moscow Desire:
Sounds like you didn't do full wipes and formats before flashing.

And as far as the black wire, I would say it sounds like some sort of shot term revision.

Try doing "all" wipes and formats. Also remember, Viper does all modding on a "stock" factory ROM, where as CM, PA, Pac, and the rest, run off AOSP, but heavily modded.
[HTC Sensation] maciek90:
I even flashed stock ICS today by RUU. It behaves like ViperS, I can get some nmea data, but without any satellite in view.

Before flashing other ROMs I've made all wipes and formats (except external SD).

Here in post #2 someone wrote that he has that wire in Sensation XE, so this week I will try to get another Sensation to check this.
[HTC Sensation] Moscow Desire:
My experience, and with the Sensation european model, is somewhat limited. And to be honest, I can't remember if the sensation has specific "h-boots" or radios that need to be flashed. Got this thing as a "trash can bound" due to battery issues, which I sorted out to use as a back-up phone. Got it late last year, s-off'd and such, but just now decided to sort the battery issue (new battery and many "bump chargings"

Regardless, a "wire" soldered across the MB, at least to me, means the device may at one time had been turned into repair for some reason. But, seeing the radios are the prime suspects, perhaps a radio firmware upgrade may be in order. This might be something to look into. Most of my experience are with tablets, and they usually have a separate GSM and GPS module.

Wish I could be of more help.

Just tossing some things out there. Although I can't recall upgrading the radio on mine, I do recall a couple of upgrades on my HTC Desire.

EDIT: sorry about the confusion on the wires. One of them, should be the antenna for the radio itself. Now, on tablets, there are 2, one for radio, and one for GPS radio. But on phones, I suspect there is generally only 1. I would guess GSM and GPS may share the same chipset. But, don't mark my word on this. I also see, the post you linked, is for the 4g LTE model, and it has 2 antennas. So maybe things are different.

I have the 3g only model,. so I can't compare.
[HTC Sensation] maciek90:
I will probably check wire this week and come back with results.

Yes, it was refurbished before I got it, so everything is possible. I don't even know if it's european model ;)

Anyway, thanks for help :)
[HTC Sensation] maciek90:
I connected these two points where the wire should be and it works! :) I have 3 satellites in view. Tomorrow I will check it outdoor.

Attachment shows where this wire should be connected.

I know it's really weird, but I found another discussion where someone who bought a refurbished Sensation had the same problem.
[HTC Sensation] Moscow Desire:
Great! Looks like the repair services are missing some steps :eek:
[HTC Sensation] RayeR:
Hi,

I have also problem with GPS in HTC Sensation XE after I replaced CPU board because of dead eMMC. But in my case I even cannot see any NMEA data going out from GPS, e.g. via GPS NMEA Tool. I checked the black cable and it's connected and it doesn't have a short. But I guess the cable connects only some RF part or LNA to the CPU board so if there would not be connection then NMEA should still go as GPS processor is probably on the CPU board. I have suspected if it's not a bug in CM12.1 ROM but tried more versions (also always wiped data/cache) but didn't helped. I search if there's some low level interface e.g. /dev/tty* that I could listed NMEA but I didn't found any info how the NMEA is passed to the system and how to tap it. I laso tried secret codes to enter some service menu with GPS test but from ~30 codes I found the only one worked - *#*#4636#*#* and there's no GPS test. So I don't know if some GPS processor is damaged on my CPU board or GPS FW corrupted.

As a last resort I would like to be able to connect my external GPS module via BT.

EDIT: Dammit, the eMMC died again during CM reflash, I send this HTC to hell. I give up the repair as probably every Sensation will die soon on eMMC bug... :(
[HTC Sensation] maciek90:
You can try to format EFS partition. If this won't help then I don't have any other solutions.

If you have problems with data partition search for boot mod and replace it with partition on sd card ;)
