[Q] Benefits of unlocking Xperia Z2 not on official Sony site - Xperia Z2 Q&A, Help & Troubleshooting

Ok, so i have my Z2 for a few months and i couldn't find any information regarding of benefits on
different ways to unlock bootloader? There is an option unlocking over a official site and unlocking
with flashtool, i kindly accept any advice.
Also, i had Desire HD, it had unlocked BL, eng s-off and everything else, but i only had to flash a rom and
thats it i can start using it. The process of flashing roms was a childs play, but on Z2 i have to flash boot.img
(i think thats kernel) over a fastboot and then flash rom from recovery separately, so is there a chance of unlocking Z2
the same way?

No difference between following Sony's guide or another method
edit-
the output is the same, just the method of getting there is different
i recommend flash tool because it makes Boot loader Unlocking easier

Unlocking by flashtool is just an automated way of doing it the official way.
It just enters the codes for you that Sony provides to save you typing them in. Flashtool is not an alternative method, it is the same method without having to type commands yourself

Unlock Xperia Ray Boot Loaders Without lossing DRM data

Guys after working hundreds of hour , i have posted a guide to unlock boot loaders of xperia ray without losing DRM data.
it is 100% tested and working fine , i also tried cyanogenmod , MIUI and all working well
you can follow this guide :-
unlock boot loaders of xperia ray without losing drm data
This method is also applicable for other xperia devices , if you are using other xperia phone then find your phone's test point here :
Test Points for Xperia Devices – Xperia Arc / Active / Mini / Mini Pro / Neo / Play / Pro / Ray
if you like my work then hit thanks , i also appeal developers to post more info about it , as i am n00b
Yeah if you want to 100% void your warranty then do this. If you mess with the TA then you WILL void your warranty. Ok I did it with my ray ages ago and just did it with my play but SE have now made trackID that needed DRM keys to work now not need them. Head over to the play themes and apps section and it's there.

Too much complicate with these cables, etc. I used for this only one paper clip. Connection was between testpoint and metal casing sim slots! So simple
And i was unlocking branded Ray with NO access to fastboot Now i have unlocked bootloader, fastboot and simfree, track-id still works olny for 15 GBP http://forum.xda-developers.com/showthread.php?t=1304417 i got also full backup of my bootloader.
If you have access to fastboot mode (blue LED) it will by free for you http://forum.xda-developers.com/showthread.php?t=1285285

You had to pay for it? . See I like the idea and if you know you won't break or brick the device then do it. But if you do hard flashing and drop your phone a lot then don't do it as it does void your warranty this way. Where we modify the TA area it is against the warranty and voids it. This is why I don't advise doing it if you are likely to need the warranty. But I will say now. If anyone has the play and wants to try this then it is actually quite tricky as it is underneath the battery and the battery need to be inserted. Also when removing the test point you can't remove the battery so..... Just pick the device up and hold the back button when removing the test point wire.

to unlock bootloader you need fastboot - in branded/locked phone fastboot needs to be enabled via PAID hardware/software.
using this method, i was aware of the void the warranty
during the whole process i did not pulled out the battery
It's still unclear for me why people want to unlock their bootloader?? Rooting can be done via the exploit so..
for custom kernel /overclocking / CM7 / MIUI etc

for installing custom roms like - cyanogenmod and MIUI
and for installing custom kernels
O allrightt I thought that was also possible with locked bootloaders
Noob question here... Is it possible to just unlock the bootloader the usual way, like I did on my Xperia Play or does it have to be done the way in OP?

yes you can unlock it usual way , infact peoples are using normal way to unlock bootloaders of Xperia phones
but if you don't want to lose track id like apps then use above posted method
I've unlocked my bootloader using the testpoint method which allowed me to install the 2.3.4 ROM on my branded Orange Ray when it first came out.
Just used DoomLord's tool to root. Really easy.
I think the only thing I'm missing is FastBoot, but I'm not sure there's a compelling need for that at the moment, to me at least?!

but You can not unlock the bootloader without running fastboot mode in s1tool!
BL unlocked in program "s1tool" = he must have working fastboot mode so why he wrote: "I think the only thing I'm missing is FastBoot" ??

For all :
Hold volume up. Connect usb. Blue light? If yes bt unlock possible with s1tool.
If no you need to go here

And we have 2 programs in testpoint metod:
s1tool - free for unlock BL with working fastboot (Bootloader Unlock Allowed: Yes/ blue LED)
SETool2 - paid for locked phone for full unlock fastboot/bootloader/sim-lock!

i think its bull**** because "FlashTool" does the same thing (flash orginal 2.3.4 ROM) without unlocking the bootloader goodbye warranty
Just one noob question.
If I unlock the bootloader with testpoint methode and flash a custom kernel, did I also lose DRM data?
Or can I then flash a stock kernel and nothing wouldn't seen that I ever flash a custom kernel. Also Track ID and so one will work fine?

If you unlock the bootloader with testpoint methode it will not cause loss DRM flashing software, kernels, etc. also will not lose of DRM data
DRM we lose when we unlock bootloader by official method (SE webpage and unlock key from that page)
Track-id and SEUS update work fine for my Ray unlocked by testpoint (paid method for branded phone)

[Q] relocking the bootloader? (need the stock kernel for sk17i)

Hello,
I have a used sk17i and the previous owner unlocked the bootloader.
Not sure what method was used to unlock it.
The problem I'm having is I want to restore the phone via SEUS, but when it asks to turn phone on holding down, SEUS does not see the phone in flash mode (flashtool does).
I presume I need to relock the bootloader for SEUS to start working again?
What are the steps to figure out what method was used to unlock it, and to relock it? (if it's the patched thing, how do I reverse it, if I need to flash the stock sk17i kernel (currently it's not a stock one), where do I get the boot.img?)
relock bootloader
I'm still find a way to get oem bootloader back..
seriously, no-one saved the original one ?
If you just want to restore to original SE's OS you can use Wotan Server for that. Its totally free, you just need to register at WotanServer.com which is also free. The Wotan Server client will download the firmware once you select the CDA. You can have any custom kernel os rom before using Wotan . You dont need to relock bootloader for this . I did this on my Xperia Mini . But if you want to relock bootloader for other reasons then the available method is for Xperia arc. This method is only if the bootloader is unlocked in normal method. If the bootloader was unlocked using setool,omnius,patch,etc. then this relocking method wont work, Which is risky . It worked on my Xperia Mini but I dont suggest it because it was posted for Xperia arc. And even though you relock bootloader you wont get the DRM rights back which means you cannot use apps like trackId, appextra,etc. All the best.

Do I have a locked or unlocked bootloader? (Neo V)

Sony Xperia Neo V
Stock ROM 4.0.4 (Updated 4.0.3 to 4.0.4 via OTA)
Rooted via DooMLoRD
CWM Recovery installed.
I need to find out if my Xperia Neo V have a locked or unlocked bootloader..?
I have read through different thread and have googled as well, but still was not able to get a concrete answer.
I have never unlocked it myself, not intentionally atleast.
When I check via *#*#7378423#*#*, it says 'Bootloader unlock allowed: Yes'. Some guys around XDA says if its unlocked, it will say ''Bootloader unlocked: Yes' but others say it will show the first one regardless of the lock state.
PC Companion and SUS can detect it just fine and I can repair and update my phone, which leads me to believe its locked.
But then, I can get into flash mode, use flash tool to load different ROMs and also have CWM installed - doesn't it need a unlocked bootloader?
And, if I am on a locked bootloader, what's the advantage of an unlocked one then, what am I missing?
Bootloader unlocked: Yes only means that your fastboot is unlocked,that your phone isn't SIM locked, not that your bootloader is unlocked.
Being able to enter flash mode, flash different rom's, cwm doesn't mean your BL is unlocked.
There are rom's that require custom kernel, if you wanna use those rom's you need to unlock your BL.
Advantage is anything that can be done with custom kernels, mainly overclock, undervolt, change some parameters...
Go to Neo V development section, in one sticky thread you can find s1tool. Get it and identify your phone with it.
Just a fact that you didn't unlock it tells that it's locked. All Xperia phones have locked BL's. All 2011 Xperias with sim lock, have locked fastboot, which means you need to pay to unlock it and by that you enable fastboot and unlock your BL.
Thanks buddy (button pressed). So, unlocked bootloader means warranty gone forever, right? Irreversible?

Well, if you use official method, even if you relock it they can see in service center, when they connect it, it will show that DRM certificate is missing. I'm not saying they will look for that, but it will be visible.
In my opinion patched bl is best option, with s1tool. Also you can relock it. As far as I know nothing will pop up on their PC.
Alright buddy, got the idea. Thanks a lot.

[Q] How to Lock Bootloader After Unlocking Bootloader

I have this PadFone S for over a week, and it's my 5th android device, but certainly the 1st one having a locked bootloader. So far I have read how to flash stock firmware, how to root and unroot, which requires unlocking bootloader first using CrowLock, how to install CWM and CM12 etc. I haven't try anything yet (still uprooted, and my bootloader is still unlocked).
One question still unanswered, is there any way to lock the bootloader after it's unlocked ? Perhaps by using the CrowLock app, or simply flashing stock firmware ? I need to be assured that any changes I do is reversible.
Thanks in advance
I too purchased the Padfone S and have the same question. Also, does anyone know if flashing crowlock will void the warranty of the phone? Can someone who has unlocked their bootloader using crowlock paste the output of "fastboot oem device-info"?
Does Asus' bootloader not check the signature for the recovery partition before booting from recovery? Given that everyone is flashing the recovery after rooting and running crowlock from the recovery, it seems so, but I'm not sure.
Anyone know if the bootloader's source code is available? I know it's based on the littlekernel, but I'm not sure which version it was built from.
Bump! I need the answer too.

Do i have to unlock my bootloader if i wanna install a custom rom

Just that
please help me i tried to install a custom before but i got a bootloop and i don't know if that's the problem
Just say yes or no
If you want to install custom roms, you must unlock bootloader.
It actually depends on the phone. You can install roms on some phones with locked bootloaders, such as some Sony Xperia phones. However, generally, an unlocked bootloader is required. I can't understand why you would post this without including any pertinent info such as what phone, which update you are, what rom you tried, what recovery you are using, etc.
