yes you didn't loose your DRM .... the latest firmware can be rooted too , flash any other stock kernels (night-elf or pwnkernel ) and then go to recovery & then flash the rootXperiazip from the second post of this thread

thanks man ill add this up...
no need, I was just pointing Gjole86 to links you already have in first post ;)
btw. do you read your PM? I sent you link about track id solution.
---------------------------
And I still see you kept link that Wurstwa55er gave you. I doubt that version of s1tool will work, as that's the older version.
since the link to setool is down (at least for me)
I found this one - hope it´s the right (free) version ;)

That won't work. To install CWM you need to have root access :) So no way of rooting .62.
Only way: downgrade to .42, root, OTA to .62, and you keep root. ;)

Since you unlocked by s1tool, and not with official method(from SE), you should be able to use SEUS or PC Companion, or even OTA(not 100% sure, but only 99% :))
So if you want root, downgrade to .42 and root. If then you want to go to .62, just do OTA update(meaning from phone, not from PC)

What's the point of this, since we have instructions here: http://xdaforums.com/showthread.php?t=1409269
:rolleyes:

And also wrong instructions.. :)
No need for back button, that's for flashmode, and since we don't need flashmode here, no need for those drivers.
Also since you put fastboot drivers in that drivers pack, you didn't put .inf file for Sony Ericsson phones. :)

Drivers for BL unlocking are in s1tool.7z pack.

I've tried to use fastboot for first time - the blue led is on, but windows is giving me headeaches. It's a fresh win7 installation with pc companion, installed Flashtool and the device is recognized, but I get an error when connecting in fastboot mode, just as in attached picture.

Why? Manual installation fails in the same way.

EDIT:
Because you have to manually rerun driver installation exe package and select your device :)
SOLVED

I've tried the new beta ICS. Now I want to go back to my backed up stock .62.
As I've understood I have to reflash old kernel and restore the backup image from CWM?

What I did:
- fastboot from a kernel with CWM
- restored .62 backup
- flashed .62 stock kernel from here: http://sourceforge.net/projects/seandroid/files/xperianeov/Kernel/Gingerbread/stockkernel/generic/

But now the phone is stuck in a reboot loop. What now?

EDIT: factory reset doesn't help. Faulty kernel?

Did you try wipe cache partition?

Now I've wiped cache, dalvik cache and did a factory reset. Device still keeps rebooting.

Did I damaged it permanently?

All I did is try out the ICS beta (flashed via fastboot mode).

UPDATE: I've downloaded the bigger ftf image (160MB) and now it seems to boot normally. The difference is that this image has /system in it.

SOLVED, thanks

EDIT: but it seems that CWM backup is unusable, after restoring it, will start rebooting again. So data it's lost.

EDIT2: I had to restore .42, root it, install CWM, update to .62. At this point I've tried to restore again the CWM backup and now it's working as it was before the ICS beta test upgrade. :=)

    (For locked Bootloaders)

    Go to these threads , instructions are provided by madfysh ,thank him

    4.1.B.0.431
    4.1.B.0.587

    [2].Bootloader

    Bootloaders are used to boot operating system on our device . Usually our phone's bootloader will be locked by Sony Ericsson during its production itself . Almost every custom rom we install has its own KERNEL which is responsible for overclocking the cpu & other stuff.To install custom roms which contains custom kernels we need UNLOCKED BOOTLOADERS .

    Unlocking via Sony's Official website

    Sony has provided a website where we get an unlock code for each IMEI no. type in that code and your bootloader will get unlocked officially . This is the easiest unlocking method possible . Wait there's more , official unlocking method does more bad than good , like
    1. will void warranty
    2. Will loose DRM & track Id related stuff
    3. No official phone updates via SEUS/PCC or OTA

    If you don't care about them please go ahead and click this LINK and follow on-screen instructions on that site

    RELOCK : TO relock use this LINK

    There is an alternative way to avoid the above mentioned limitations , it is called SEtool


    Unofficial Unlocking (S1tool)

    This method overcomes all the three limitations , but you will need to do a little work manually , this method introduces us to a new word called TESTPOINT(Of all those 8 golden points , only the point which is indicated by the arrow is the TESTPOINT) .For NEO V testpoint is located deep within a slot covered by a black patch which is above our SIMCARD slot (see this picture and remove the black covering) .
    attachment.php

    It is used for function-test during production. & we are going to ground that testpoint using a simple wire .instead of that pin you can use any conducting material (wire , safety pin , paper clip , but make sure its diameter is not more than that of the testpoint else it will touch other points and might brick your phone)
    attachment.php
    Ground : ground is refereed as the negative battery pin of the phone
    attachment.php

    Steps
    1. download & extract SEtool from this thread , if not available [LINK 2] , [LINK 3] , [Thanks to Madfysh & Wurstwa55er]
    2. Connect test point to the ground and attach USB cable. Wait while Windows shows finding new device, disconnect test point immediately. Windows won't find appropriate drivers. select drivers manually from the archive of SEtool. Agree to install 'untrusted' drivers.
    3. Reboot your PC
    4. Run s1tool, press 'Patch semcboot' and follow tho on-screen instruction.

    RELOCK : : ONLY THE RESTORE BUTTON PRESENT IN S1TOOL WILL RELOCK YOUR BOOTLOADER , other procedures will not work.Connecting TP to ground while using RESTORE button is not necessary.

    EXTRA info : (thanks to DooMLord)

    [3].ClockWorkMod Recovery
    ClockWorkMod Recovery also known as CWM ,is a Custom recovery for android devices which is very useful for
    1. Installing custom roms ,kernels,patches , flashable zips.
    2. Backup & restoring your rom
    3. Wiping system , cache & other partitions
    4. Mounting sd-card & other partitions
    5. & more :p
    attachment.php

    Steps
    1. Enable USB Debugging on device
    2. Connect your device using usb data cable
    3. download and extract CWM install.RAR
    4. Download ADB Drivers ADB drivers & install them & Run install-cwm1.cmd
    5. Follow on screen instruction

    Switch off your phone , press the power button and keep pressing the volume down button when you see Sony Ericsson for the first time until you see CWM(not the logo/boot animation , the SONY ERICSSON screen which appears first) task COMPLETE
    [4].Nandroid Backup
    Nandroid backup is a backup/restore option available in your CWM . Backup you current SE rom for saftey , select backup option and let it do its work . The backuped files will be in ClockWorkMOD folder of your SD card , keep a backup of this backup in your PC in case when anything goes wrong this backup will save you

    [5].Kernel Installation
    Kernels(boot.img) are the main base for any custom rom you install , kernels are installed using FASTBOOT feature of android ADB , there is a simple logic you need to remember before you flash any kernel

    Stock Rom = Stock kernel
    MIUI Rom = MIUI Kernel


    before you flash any custom rom make sure you've installed its related kernel (boot.img)

    Requirements :
    1. Flashtool
    2. Download Flashtool package & Drivers
    3. CWM backup of stock rom
    4. Fastboot

    Instructions : (thanks to doomlord)

    Flashing Kernel (boot.img):

    1. this WILL NOT WIPE ur data
    2. the custom kernel will be provided as boot.img file
    3. just copy this file to fastboot folder(folder where fastboot package is extracted)
    4. power down device and get into FASTBOOT MODE (LED notification turns BLUE)(switch off device hold menu key & plugin usb) with usb-cable connected to PC
    5. once u are in fastboot mode open command prompt and navigate to the folder containing fastboot files then just use the following command to flash custom kernel:

    fastboot flash boot boot.img

    6. once flashing is complete you will get a prompt on pc saying that everything is ok
    7. now just unplug ur device and u are on the custom kernel


    Overclocking

    1. DOWNLOAD SetCPU from XDA
    2. Select automatic detection of speeds ,and allow root access to Setcpu
    3. default speed is 1024Mhz & maximum overclocking is based on the kernel you flash

    Visit this thread for list of available kernels http://xdaforums.com/showthread.php?t=1313445

    maximum overclocking may harm your device
