Hi,
In case anyone (like me) has issues installing the S1boot driver for your xperia, to be able to flash other firmware, here is the link :
http://forum.xda-developers.com/attachment.php?attachmentid=718060&d=1315877046
This driver will install itself after you run the executable file dpinst.exe after having extracted the archive.
With the driver you can use the flash tool (combined with your phone booted in flash mode (volume down + usb connect)) to flash other firmware on the phone.
P.S. i'm not talking about fastboot mode, but "flash mode" ;-)

i dont think you have to unlock the bootloader to flash your phone, you have to enable usb debugging in your phone ,settings>applications>development>usb debugging
pls correct me if im wrong
Hi,
As far as I know you "have" to unlock the bootloader before being able to flash custom firmware on the Phone.
I unlocked the bootloader via the sonyericsson site link :
http://unlockbootloader.sonyericsson.com/
I use 4pda.ru firmware+kernel from this thread :
http://forum.xda-developers.com/showthread.php?t=1424121
Reason I dont use CM or MIUI is that I need a 100% functional phone (both corporate and private usage, that's why) . I encourage the development on CM and MIUI, don't get me wrong here
You can find more information about unlocking, rooting and flashing custom kernels and firmware on this XDA forum.

how about flashing through CWM recovery like the previous xperia? is it any different? because before the msm7227 and qsd8250 bootloader been unlocked, people use CWM recovery to flash rite?

You can setup CWM and flash ROM on unlocked device, but you can't flash kernel and baseband.
So current situation is: you can't flash CM or MIUI (which requires their own kernels) on unlocked device, but you can flash stock-based mods like repack4pda (which works with stock kernels).

You both mean locked right?
Hey guys, I'm gonna get a brand new Xperia X10 Mini Pro in a few days. I wanna install MiniCM7-2.1.9, and to use that rom I also need to install the nAa kernel, which requires an unlocked bootloader.
So my question is, say if I need to revert everything back to stock (rom, kernel, lock bootloader), for warranty purposes for example. Well, I know that the kernel and rom can be flashed back to stock using flashtool or SEUS, but what about the bootloader?
If I remember correct, you have to lock the bootloader first or else an unlocked bootloader won't work with a stock rom & kernel, which will result in a hard brick right?

Bootloader cannot be locked again. So if you are unlucky, you will get brick and lose garanty. =)

Yes, sorry, i am used outdating info((
ya I did my research and S1Tool can re-lock the bootloader. But am I correct though? My question wasn't really answered...
You have to flash back to stock rom and stock kernel if you want to re-lock your bootloader. Just when you're on stock rom/kernel, then you can safely re-lock your bootloader.
sorry, more like I install this rom?
http://forum.xda-developers.com/showthread.php?t=1434001
must have some specific fw to flash the kernel? and then it must unlock the bootloader? could post a tutorial with installation abrçs
first requirement to install a custom rom is a custom kernel and to install a custom kernel you would have to unlock bootloader.
sorry there is no specific tutorial for the installation of this rom.
what i can only provide to you is a link for unlocking bootloader here.
for the installation of the rom, check other roms for installation instructions.
they basically have the same approach.
I understand, I already unlocked the bootloader him, he was sk17a xperia mini pro, and I swapped it for a sk17i fw 0.42, now I have flashing a custom kernel, I use this rom I posted just above, so that my doubt that, if I can flash the kernel with this fw 0:42? why some are not compatible, then I dissso replace the kernel, I'll have to unlock the bootloader again to put the CM7 aosp? backing up the kernel and the stock rom? hugs
This ROM, which link you gave in first post, has own kernel, which is the ONLY kernel that works with this ROM. The kernel is included in the post.
CM7.2 and CM9 have also own kernel, that works only with specific ROM.
Rage Kernel, X Kernel and others are for stock(and stock-based) ROMs, for example Hybrom.
Hello
I have a few questions about the hole "thing" cause this is my first android phone and on apple there was just the option jailbreaked or not jailbreaked
My first question is about the bootloader.
since i was reading the thread "[FULL ROOT] Community RootKit! (ASEC vulnerability) {v01} [20140615]" i am asking me why should i unlock my bootloader when im able to get root without doing this?
Is there any special point for wich i need the unlocked bootloader or is it just written for the people who unlocked there bootloader already?
Then to second question is about the sequence.
Am i right when i
1. get root
2. install cwm or twrp
3. install custom rom?
by the way: is there any huge difference between twrp and cwm? because at the table "Kernels" there is the TWRP for the Xperia T2 Ultra and an unofficial version and from CMW is an unofficial version too? Wich should i use?
and my last question is should i wait for version 2 of the RootKit or are there just small differences?

Bootloader unlock is required to install Custom kernels like DOOMLORDS kernel. In case if you dont want that then no need to unlock BL.
Just follow this post http://forum.xda-developers.com/showthread.php?t=2784757 to get root on Locked Bl and then revert back to .402

hi manu44,
first thank you for the answer.
but it is possible to root and use an custom rom with an locked bootloader or?
is there a away to do it step per step?
i mean first root with rootkit, then later install an custom rom ? or do i need to do it all at one time ?

A custom ROM is different from a custom kernel. Some custom ROMs do not require custom kernels (because they use stock kernel), but others do. So it really depends on the custom ROM that you want to use. Instructions and requirements will be posted in the respective ROM thread.
But if you want to use a custom kernel, then you will need to unlock the bootloader first.
And obviously, if you want to flash a custom ROM that needs custom kernel, then you will have to unlock your bootloader first.
Even if you want to flash a custom ROM that does not require a custom kernel, you need to first root the phone with the RootKit. Because flashing custom ROMs is usually done via recovery, and recovery installation requires root.
Hope the above is not too confusing.

Thank you
So just to be sure.
I Run the toolkit for root
Then i take twrp or cwm
And then i flash a custom Rom wich use stock kernel
And that can i do with a locked bootloader?
What can be different in an other kernel?

Yes, run Rootkit, install recovery (TWRP/CWM) and then you can flash custom ROM which uses stock kernel.
Custom kernels allow functions such as overclocking, undervolting, etc.

Big thanks to you
Now i know that i can keep my bootloader locked.
Take note that by modifying your device you warrenty is voided and you can posibly brick your device
(brick meaning dead phone) aka brick

Or you can use the toolkit on .55/.69
Then follow Nuts thread and http://forum.xda-developers.com/showthread.php?t=2784757
this would bring you back to .402 and have recovery installed by default on Locked bootloader

then i have 2 new questions
1. How can i downgrade my phone ? just download the fw and use flashtool?
got an iphone till now and there it was a hard work to do it ..
2. is there any difference between locked and uinlocked bootloader? i mean in the point of restoring so that i have my warranty back?
1. There's now an even easier way to root the 402 firmware that does not require you to downgrade first:
http://forum.xda-developers.com/showthread.php?t=2784900
But note this post, where you have to change something in the install.bat file for it to work on the Z2:
http://forum.xda-developers.com/showpost.php?p=53480221&postcount=81
2. It's a little more work if your bootloader is unlocked and you want to relock it before sending it to the service centre. You need to have your TA backup before doing so. If your bootloader is locked, you just have to remove root via SuperSU before sending it in for service.
Coming from my HTC One X, the bootloader was "locked" in such a way that I had to flash the kernel in fastboot every time...
Does the kernel in the ROM zip files flash from the recovery on the Z2 if I flash the ROM from recovery?

i dont fully understand
you must unlock your bootloader to flash a kernel with xperias otherwise it will brick
when you flash a kernel it stays that way untill you flash another kernel
some stock based roms contain stock kernels so you will have to reflash a kernel which has a recovery
take note recovery is contained in custom kernels
So are you telling me that ROMs flashed on Locked bootloaders do not flash kernels?

Yes, that's correct. Locked bootloaders can only use stock kernel. To flash a custom kernel (i.e. non-stock), you need an unlock bootloader. So if the ROM is for locked bootloaders, then it's not flashing a custom kernel, so to speak.
