[Q]Considering to Unlock the bootloader of my Xperia S!! Just need to ask something

But I'd really like to ask some questions...
Am I losing the warrenty forever, without anyway to get it again? (or i already lose it, since my phone was bought it in April 2012?)
Watching some guide, even not by official way, i have to submit my IMEI code, meaning that I must let sony know that my phone is unlocked?
So even if i reinstall everything, sony will still have a record that i have once unlocked the bootloader??
Is bravia2 working on jellybean with unlock bootloader? (I thought it wont works, some people said it works now in jellybean)
Thank You!!

I editer your post with numbers so the answers are clearer:
1. As far as i know, you still can relock bootloader before taking to any center. In theory, they can only deny warranty if the problem was caused by any hardware or software modifications (for example CPU burn for overclock).
2. In theory, yes. They will know. I am not sure if the service center check that info in their data base.
3. In their DB, yes. But the people at the service center might or might check that.
4. I think that only video...

[Tutorial] Xperia Z2 Tablet Bootloader Unlocking/Relocking

Quick tutorial for unlocking & relocking the bootloader of the Xperia Z2 Tablet
this is the official way to unlock bootloader
WARNING!
MAKE TA BACKUP BEFORE UNLOCKING BOOTLOADER!
​
if you want to backup the TA or keep ur DRM keys,first root the device and then check this out
Warning!
This procedure will wipe the /data partition of your tablet, so you will loss all ur stored data, settings. SDCARD will BE WIPED!!!
For Xperia™ devices released 2013 or later (for example Xperia™ Z and Xperia™ ZL), the SD card of your device will be formatted and you will lose all content (for example photos, music, videos) when you unlock the boot loader.

DRM keys WILL be lost forever
schaggo said:
I'd add what losing DRM keys means, e.g. no more Music ID/Gracenote within the Walkman app plus probably most importantly, as asked all the time and all over the place in the T/mint forums: loss of Bravia Engine.

older Xperia devices sometimes got issues after unlock of bootloader (BRICK after FOTA update) - you have been warned
why to unlock bootloader?
u can flash custom ROMs/Kernels
u dont need to worry if the new firmware can be rooted or not as with unlocked bootloader u can always ROOT ur device
Sony gives sneak-peaks/preview builds of latest OS which requires unlocked bootloaders, as they did with Xperia 2011/2012 line, so who knows may be Sony may give early builds of next android OS
Most of this is taken from lollylost100's his tutorial from ARC thread (all credits for that concise tutorial go to him, i have elaborated on a few things and added device specific changes)
btw i dont have this device, most of this testing was done remotely on a users phone... so thanks a lot to him for helping out!!!
[ before we begin unlocking bootloader ]
download the fastboot package
IMPORTANT: if you are using Windows 8 you will need to enable few things to allow driver installation
download the latest FlashTool Xperia Driver Pack and install fastboot drivers (common) & adb drivers for this device from the list!
make sure u have a windows PC with USB cable to connect the phone
power down ur tablet and keeping the Volume Up button pressed connect the USB cable to PC this will trigger FASTBOOT mode and windows will start driver installation, which should be automatically done
once drivers are installed just disconnect cable and power on device
[ how to unlock ] (official way)
Go to: http://unlockbootloader.sonymobile.com/ and read everything!
At the bottom click 'Start Unlocking the Bootloader'
First, you should confirm that it is possible to unlock the boot loader of your tablet by checking the service menu. On your tablet, open the dialler and enter *#*#7378423#*#* to access the service menu.
In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
Click to expand...
Click to collapse
after u have verified that u can unlock bootloader, scroll to the bottom of the page and click "Continue"
you will get numerous prompts, read all info and if u agree click on "Accept"/"OK"/"Proceed"
finally u will get a "Create Unlock request" page, enter your IMEI (sometimes the last digit needs to be removed for this to work), name and email address
You should now receive your unique unlock key via EMAIL, SAVE THIS KEY SAFELY
Extract fastboot_with_Android_USB_file.rar and open fastboot folder
Hold SHIFT and right click on the background of the folder
Select 'Open command window here'
Connect your tablet in fastboot mode (turn phone off, hold Volume UP button and plug in USB Cable) [make sure drivers are installed as explained above)
In the cmd windows type in fastboot.exe -i 0x0fce getvar version
If a value is returned (it will return 0.5), it means the tablet is correctly connected
Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which u received earlier.
You're device should now be bootloader unlocked
If this tutorial is too much for you then itskapil wrote a step-by-step guide (and recorded a video also):
-Instructions: http://www.theandroidsoul.com/how-to-unlock-bootloader-xperia-arc-play-neo-pro/
-Video: http://www.youtube.com/watch?v=LRH3pC7MhEA
(the above videos and some steps are for Xperia 2011 devices, but most the steps are same for Xperia Z)
Relock procedure is posted here
regards,
DooMLoRD

Relocking bootloader
With the latest release of Flashtool it is now possible to relock bootloader.
Download the latest flashtool from:
http://forum.xda-developers.com/showthread.php?t=920746
Important
DO NOT USE ANY FTF TO RELOCK BOOTLOADER! THOSE OLD FTFs DO NOT WORK FOR THE 2013 DEVICES!!!
before u relock bootloader u have to be on pure stock kernel (flash only the kernel.sin using flashtool), else the device WILL NOT BOOT after relock
Steps:
now start Flashtool and click on BLU button
u will be asked to connect device in flashmode
once u connect the device u will get a prompt to "Relock"
click on it and when prompted disconnect the device
Want to UNLOCK again after relocking? read this!

It is very confusing indeed. In other words it actually says, do not unlock yet. Wait for an exploid to be found and released so you can root without unlocking the bootloader. Then you can safely make an TA backup, and then safely unlock the bootloader. If you unlock now, your warranty is void.
Sent from my SGP511 using XDA Free mobile app

When a root exploit is found, unlocking the bootloader or backing up TA is not necessary anymore. (Except if one wants to install a custom ROM or custom kernel.)

Yes, but that's why we here. To install custom roms and kernels I mean..

OK thanks for clarifying that! I figured that was the case. And yes thats why I'm here, custom rom! This thing would rock with Slimkat or something similar (if it ever gets ported).

For all those who worry about unlocking I would like to cite Doomlord from the Z2 phone CWM recovery thread:
Dont worry I have been on unlocked Bootloader on all my Xperia phones and honestly there is no functionality that I missed.

Actually I have customs on all my device, but on z1 (same for z2) never needed one, just root and exposed framework+adaway.
About unlocking, as far as I know the only "useful feature" you will disable should be the bravia engine.

Bravia Engine (or X-Reality) is not "useful", it's just oversaturating and exaggerating colors in an unnatural way. A feature for noobs, just like "Beats Audio" is a bass-booster for music-unsensible juvenile oomph-oomph listeners.
So it can easily be discarded without ever looking back.

i agree on that but it voids your warranty.
Im not saying we should all wait till your warranty is over, but at least fully test your device before making a irrational decision, dead pixels, speakers, loose corners (have had 2 devices with that problem), waterproof test, etc...

True, last thing you want is to void the warranty and find out something covered by it goes bad. I can wait. This baby is running nice so far. Dont need custom rom, but im missing that root!!

That's the new rule implemented in kit kat, not Sony's fault.
This problem can be solved if root is available
Sent from my C6603 using XDA Premium 4 mobile app

what s that rule? I have been using kitkat with omni since it released in note 2 nd hammerhead. initially it had issues with selinux, then i wrote a patch to omni source as well. but here selinux is not the bad guy I suspect something to QUCOMSEC nd drm keys. l have root, can u give me pointer to fixes. This s my first sony device so I have idea, Thank u

custom roms probably already coded it, thats why you didnt encounter the problem. Explanation of the problem can be found here provided by the OP.
If you have root already you can try both of the following,
*please note that Ive tried the xposed module on my Xperia Z running stock kit kat not Z2.
**please note, back up your stuff before proceeding, just incase something goes wrong and wipes your files.
[XPOSED] HandleExternalStorage requires Xposed framework installed. I am currently running this module and working fine.
[Playstore] SDFix: KitKat Writable MicroSD this was suggested by kingvortex in another thread, havent tried it yet, but the reviews seem to suggest it works.

Sorry - but I just have to add my own experience as a "noob".
First: I gave that X-Reality thing a deeper check; I had two Z2 tablets for simultaneously checking how HD videos look with and without that X-Reality feature.
I usually dislike all kinds of "enhancers", whether for audio or video enhancement. First things to switch off.
But I have to admit: X-Reality really works. The Z2 with the feature on produced a far more lively, absorbing experience. It's hard to tell what exactly makes the difference, it's just there. Among other videos, I used the famous Samsung "build-a-helicopter" video for comparison. Contrasts were better, details improved a bit, colors got slightly accentuated, became deeper. The slightly oversaturated color reproduction of the Z2 of course is there - but with and without X-Reality.
In short: Videos were just more fun and pleasant to the eye.
Best of all: You can switch it off; but you don't want to.
To be honest: X-Reality is THE feature preventing me from rooting the Z2 now. I don't care for DRM keys, I don't care for a true-to-life color rendition. But I care for pictures and videos looking simply better.
Quite lenghty explanation - but I guess this is an issue to consider prior to unlocking your bootloader and waving X-Reality goodbye forever.
Second: Beats Audio is a bit more than a "bass-booster for music-unsensible juvenile oomph-oomph listeners".
I seem to be a 45 years old "music-unsensible" listener. In fact, I am a former professional musician, knowing just a bit about sound.
I don't see anything wrong with utilizing software techologies to overcome some of the acoustic issues tiny smartphone or tablet loudspeakers suffer of. It's not just about creating that "oomph-oomph" redneck sound; it's about compensating the shortcomings of problematic speaker setups.
That's what devices like HTCs One clearly demonstrated.
I'd be quite happy if our Z2 had anything similar to offer. :/
So please try to be a bit more reluctant if it comes to demonizing modern features not everybody may like, but which will be gone forever if you go the hasty way.

Unlock Bootloader

How to unlock bootloader on Sony Xperia M5.
How to unlock bootloader
1.In http://developer.sonymobile.com/unlockbootloader/ choose Sony Xperia M2.
2.Submit Email
3.Submit IMEI
4.And unlock bootloader with intruction.
You get the code? Then we continue.
Download the latest version here or Flashtool http://www.flashtool.net/downloads.php
After installation, go the path C: \ Users \ username \ .flashTool \ registeredDevices here and create a folder with the code-name of your machine (you can find out if flashtool click on BLU and see where in the log are in line «Current device» for example, in line 09/045/2015 23:45:08 - INFO - Current device: C2104 - AB100C2DE3 - 1272-4136_R5B - 1269-5420_15.3.A.1.17 - WORLD-a_15.3.A.1.17 code machine will AB100C2DE3. Code which will write your name and location).
Later in this folder, create a text file and name it «ulcode» (without the quotes). Open, and in it write your unlock code, that you have on the site Sony. Save. Write code very carefully.
Now open flashtool and press the BLU. If everything is correct, in line you should write your code, pressing unlock. All should be ready to unlock.
Working on:E5633
I am not responsible for the broken device. Whatever you do, you do at your own risk
After unlocking bootloader will void the warranty

I forgot write. I get unlock code with my IMEI.

Interesting, I checked my Rooting Info as per the guide and it does say allowed.
I think giving Sony my IMEI will potentially void my warranty claims? Let me think about it.

I think, in service centre check bootloader. If bootloader not unlocked, warranty is valid.

This method is working also on M5 dual, 6533
But the next step should be how to gain the root =)

Yes, you can relock your bootloader with Flash Tool but your DRM keys are gone forever, proprietary Sony features won't work even after relocking...
Also, it's veeeeeery unlikely, but they may check if your DRM keys still exist in Sony Service Center, in case they don't find them they'll know you've unlocked your bootloader...

How about port TWRP or CWM on Xperia M5 ? If we port recovery, we can get root.

I think there's a way to do it by backing up the TA partition. That's how Sony Xperia Z1 started. We root, unlock bootloader, backup TA and when we relock, we can actually restore the TA and DRM key

Err, no. To preserve your DRM keys you need a way to root without unlocking the bootloader (e.g. using an exploit), then you make a backup of your TA partition which will contain your DRM keys. If you unlocked your bootloader without a taking a TA backup first, your DRM keys are gone forever, even if you root your device afterwards and make a backup of your TA partition you won't have any keys at all because they already were wiped when you unlocked the bootloader, this applies to any Sony device.
In other words, currently there's no way of unlocking M5 bootloader and keeping your DRM keys, the hope is Xperia Z5 series or other flagship devices, they draw attention of many developers and like what happened with Z2 and Z3, for example, locked bootloader users probably gonna start a bounty or some kind of incentive for a way to root the locked variant of those flagships, eventually they'll find an exploit that probably can be ported to other devices with less development activity, like Xperia M4/M5.
It's the cat-and-mouse game, new flagships are released, devs will research possible exploits to those new flagship devices and when one is found it's very likely to work with most devices released at the same time (and that probably are unpatched too). Also, in Sony devices, if you have root in one firmware version, you'll automatically have root in any new firmware too (using tools like PRFCreator or dd Flasher)...
(as record, towelroot, developed originally for Galaxy S5, could be used in a lot of Xperia devices from that time, and the Xperia Z3 exploit was successfully ported to Xperia E3 as well and could probably be used in similar devices released around the same time like Xperia C3 and others)

Thank you! What's the chance of the M5 properly supported by custom rom, like FreeXperia and CyanogenMod?

Hello Duke,
On Sonymobile page for M5 it is showing that it is due to update to Android 6.0 Marshmellow which is coming soon.
So what do you think? I heard root isnt possible on Android 6.0 , and if rooted they will make it hard for the users.
Is it going to be well? or Rooting is history?
p.s - When I asked a youtube user for the bootloader for M5, he said " root method has been out for months, it would be great if you can put Google to use. no offense". Is this true? whats going on?
thank you.

FIDO keys are unique authentication keys by GOOGLE/YUBICO
(as per WIKI PEDIA) " Universal 2nd Factor (U2F) is an open authentication standard[1] that strengthens[2] and simplifies[3] two-factor authentication using specialized USB or NFC devices[4] based on similar security technology found in smart cards.[5] While initially developed by Google and Yubico, with contribution from NXP, the standard[6] is now hosted by the FIDO Alliance.[3][7]
the problem is to have root access on Z5P running on MM (kernal 3.10 or higher) you must FLASH the kernel. and flashing kernel can only be done on UNLOCKED BOOT LOADER. WHEN you unlock your bootloader, sony by default WIPE the following from INTERNEL MEMORY
1. all user data
2. photos /logs / apps
3. wipe TA partitions (so the all keys are GONE)
i never had oneplus, but all i know that SONY XPERIA falls in the devices which are the hardest to root.

You've been so helpful! Thank you
One last thing. What differences could you see after and before rooting it? Battery life wise. Speed. Everything? Just a general view.

with ONLY having ROOT ACCESS, it will
1. will give you better control over your hardware, and you can change sensitive settings (CPU CLOCK etc) (not recommended though)
2. control over disabling removing XPERIA APPS ( whatsnew, software updater, lounge, xperia mobile transfers,
3. Control over other system apps locked by SONY ( GOOGLE PHOTOS, Hangouts, DRIVE, BOX,
4. Clean my Delvik Cache etc whenever i want
5. control battery draining apps and their wakeups by controlling apps like PURIFY
6. backup/restore KEYS (DRM/FIDO)
with having ROOT ACCESS + UNLOCKED BOOTLOADER
all above and
1. flash custom KERNELS having RECOVERY (something you can BOOT into bypassing Android)

2. flash flashable .zip apps from recovery (custom made themes)
3. change android ECO SYSTEM ICONs etc via recovery
4. install CYNOGENMOD (if available, as of now there is no CM for Z5p)
5. Install MIUI (when available)
6. flash other MODIFIED ROMS

Unlocking the bootloader, anything specific I need to do?

I used to have XZ1 Compact where unlocking bootloader wiped something somewhere and camera stopped working.
Is it the case with XZ2 as well? Do I need to be aware of anything similar?

Camera still works of unlocked with newest firmware.

Hello,
First, thanks a lot for the work you made around XZ2 Compact, I come from french forum, and many tutorials quote you.
I wanted to know if there is still a problem to unlock bootloader of the Xperia XZ2 Compact (like losting DRM files and not being able to use camera anymore).
My current build is 52.0.A.11.3, and I would like to unlock bootloader from the developer sony website directly then root my device (I definitely can't imagine using Android without root haha)
So in this following message

you're saying that unlocking bootloader isn't a risk anymore, can you confirm it if I'm right, especially with my current build.
Best regards,

Oh thank you
Yeah, unlocking on the newest stock doesn't harm the camera. It changed since PIE. (Maybe change again with Q [to an even better result]).
So don't worry about your camera on unlocking.
If you use a SODP based custom rom the stock DRM is not used for the features. (But the camera there is work in progress and get heavy work over the next months).

Oh, that's a really great new !!!
I think I'll stay with the stock rom, I just want to unlock the bootloader, flashing TWRP, then install root (for using Titanium Backup + AdAway + Xposed Framework for XprivacyLua).
Can you just confirm that my wish are possible with the procedure I wrote please ?

I don't use this stuff except Titanium backup, but if it works for PIE, why not?

Well, the most important is how to root my device, the use of root I'll do isn't important tho.
But I guess as you didn't say anything about the procedure, I can go for it then
