YEAH...what the proper prepaired????
this my answer..
1) look on my signature (easiest guide unlocking bootloader)
2) flash custom kernel and flash rom (no need back to 2.1 or stock)
3) Yes Unlocking with stock rom
4) It depend on U (for me i wanna the rom with the nice and beauty colour one)
I use "TIM3 v1" + "nAa v8b" ( I mean where u wanna go with fast speed?)
5) YES
6) Use flash tool and download stock kernel (search it on XDA)
7) NO -u can unlock by easiest guide (on my signature there)
8) U can't DIY...(if your phone still under warranty send to them)
for me i got 4 times hardbricked and they repair for me without fee
BUT PLEASE MAKE SURE YOUR DEVICE IS 11W28 BELOW
(see on phone..PULL OUT YOUR BATTERY AND YOU CAN FIND THERE
hope this help

1.The easiest way to unlock bootloader is with s1 tool. Just connect your phone with usb debugging on and open s1tool and unlock bootloader.( It might brick your phone, I dont recommend you to unlock bootloader)
2.Unlocking bootloader does not change your rom, If you are on 2.1 then it will not affect it. Switching between roms is very easy, just use recovery.For kernel use flashtool
3.You dont need to be on stock rom to unlock bootloader, it can be done through custom roms also
4.From my opinion alfs v6+gingierdx is great. It is very fast for daily use but not very good for hd games.
5.Dont know
6.You can always return back to stock kernel using flashtool and stock kernel ftf
7.Your bootloader will not be lock if you go back to stock rom
8.You cant unbrick your phone if it is bricked during unlocking bootloader, you have to send it to sony ericsson for repair

Thanks very much guys, but I am scared if I brick my device as I can't unbrick it then

I told u...check the MFC date (pull out your battery)
see the **W** (date of manufactoring)
If '11W28' = 2011 week 28
bellow 11W28 is safe..
Above 11W29 is risky..
but nobody force u to unlocking it..
but (also) some nice and beauty rom need custom rom
it totally can't run on stock rom...that why i got my 4th bricked yesterday..
and got a new X8 today with 11W23....
release my tension because can't unlocking bootloader

NO.. not for a hardbrick....
check out some newest threads here which hard brick because of bootloader unlock.. almost all of them not solved and go to SE center..

Ya unlocking bootloader is a bit risky!
Be Careful if your planning to unlock it.

Thanks guys for your help, I really apreciate it. For me the date is not a problem. However is there a possibility of getting bricked during unlocking the bootloader? Well atleaset has anyone bricked their device by unlocking the bootloader and fix it without sending the phone?

U mean if we go back to stock 2.1 with unlocked bootloader, we get bricked?

1) What is the best and easiest way of unlocking the bootloader? From 2nd reply.
2) After unlocking my bootloader, how do I switch ROMs, Is it like normal or do I need to go back to 2.1 first AND GO BACK TO STOCK KERNEL?
You don't need to go back to stock. The unlock won't do a thing with the rom.
3) Do I need to be on stock ROM to unlock my boorloader?
I could only unlock my bootloader from stock 2.1 (tried under GingerDX), but from stock it was easy.
4) What is the best kernel and ROM combination for you? - PLEASE ANSWER THE POLL ABOVE.
For me it's FroyoPro 2.3 ans Alfs
5) Can I Sim Unlock my phone later after unlocking the bootloader?
Can't say... mine was simfree out of the box. (If your phone is not simfree be aware! not all can be unlocked and could cause hard brick)
6) How do I return back to stock kernel?
Just flash back stock kernel file.
7) If I go back to stock ROM will my bootloader be locked again?
No, the bootloader cannot be locked again.
8) If my phone gets accidentally bricked during bootloader unlock process, can I unbrick it?[/B]
At home it is really unlikeley. There are special cables that can do the trick, but they need an expertised technician and a lot of money (for the cable)
Hope it helped for you
My phone is a 11W23 white one with cypress and is unlocked. For You what is the best? What You want? Speed, stability, low battery drainage, cool 3D games etc... For me it was little battery use and high speed with a tad of cool UI.. for this FroyoPro 2.3 and Alfs (Alfs is not needed for froyo pro! so no need to unlock only for that)

Ok thanks guys for answering all my questions about unlocking bootloader. All my doubts are clear

[Q] Can I get my guarantee back after i unlocked bootloader?

My X8 was rooted and unlocked bootloader. I know that I will lost my guarantee.
But I have problem with my LCD touchscreen. It's the hardware problem, not software. So, I think I can get my guarantee.
how SEC identify the rooted and unlocked phone?? Can I get my guarantee back??

Re-lock bootloader, flash stock firmware and send your phone to Sony

I read that re-locking a bootloader with a custom kernel installed would brick your phone, is that not correct? I belive the correct way would to be to reflash your phone to stock using SEUS and then lock the bootloader?
I'm not saying that eagleeyetom is wrong, I'm fairly new to this type of thing but I do remember the unlockbootloader guide stating not to relock bootloader with a custom Kernel installed as you'd brick the phone. Just trying to help

thanks for help.
my touchscreen is broken. I wanna change it to the new one.
I should relock my phone, right??
Are they check the software?? I think i've got the hardware problem..

Yeah, you're right. You should first flash stock kernel and then re-lock.

thanks.. i'll try it..

then help me how to flash the rom
note : i read many thinks about this but i am still don't know

Hello,
First of all you need to root your X8, download Flashtool, install it, run it, install drivers from folder and go to Applications>Unknown Sources(check)>Development>USB Debugging after that open Flashtool and make sure your phone is recognized by the program.
For custom kernel you need unlocked bootloader, for this better search in forums. It will be a pretty long story to explain you here. There are some guides.
There you go: http://forum.xda-developers.com/showthread.php?t=2043491

Check your manufacture date under battery, if it's below 11w29 then you can unlock bootloader but if it is not DON'T EVEN TRY !

I want unlock my bootloader, but..

Hey guys. So, I want unlock my bootloader, but I have maaaany questions.
This Xperia X8 was of my friend. He gave it to me. Time ago he tried to unlock the bootloader, it seemed to be successful, but he hardbricked the phone. Fortunately, the phone was under warranty, so he sent the phone at S.E . Now it is in my hands. :good:
First, I put custom roms. First, Froyo Pro, now I have MiniCM7. Now I want unlock the bootloader for a custom kernel.
I searched many threads, and I read this :
http://forum.xda-developers.com/showthread.php?t=1693308
Do you think this is good? I know that unlock the bootloader is dangerous, but this procedure is a little bit more safe?
My friend had followed another tutorial, but I think he failed because he was on PrimeHD when he tried to unlock, and in the PC : No PCC companion.
I read that, I MUST HAVE stock rom and PCC Companion. Is this right? I have MiniCM, if I use PCC Companion, can I have the right stock rom?
It is possibly to unlock the bootloader , even if the phone was sent to S.E for repair?
Now, in the battery I read 11w15, and in the inside of the phone,
IC: 41708-A3880091 FYT 12W08
It is possibly to unlock?
If yes, anyway can someone give me support?
Thanks guys

DONT unlock it, you could end up again with a hard bricked X8

NO. You can't unlock your bootloader if 'unlock bootloader allowed = no'
Since you cannot unlock bootloader, therefore you cannot flash custom ROM on your phone.
Rooting phone do not always need bootloader to be unlocked. There will be some ways available to root your phone with LB.
Also there will be some ROMs available that can be flashed over LB. But they'll be based on stock and will not have more features rather than stock features.
You just need to search here on XDA
I suggest you not to flash any ROM on LB. You'll eventually get bootloops and maybe hard brick.

Nope! As much as I know, you cannot change status from 'no to yes' rather than changing your motherboard to do so. It'll cost you more than you buyed it.
It is related to TA Partition. And EVERY phone has its unique TA. So no one can change its status. Flashing other phones TA to your phone will brick your device.

UB = Unlocked Bootloader
LB = Locked Bootloader
You can only flash ROMs with LB label.

In such case you need to roll back to your previous android version. I don't think you could unlock your bootloader. But if you are telling it was 'yes' before, then you should try.
No matter your phone works with every sim or not. TA Partition contains DRM keys as well as many other things related to network, warranty, services which get erased after unlocking bootloader.

Yes you can flash any stock ROM through flashtool. You just need to download appropriate firmware (.ftf)
Even you could update your phone through PC Companion. The latest version is 5.1.1 Available.
BTW why are you trying to flash stock ROM? Are you using any custom ROM already?

You mean bootscreen, right?
Just because of bootscreen are you going to change the entire ROM?
You could change bootscreen manually. Your phone just need to be rooted to do so. To root your phone use kingroot app. If your lucky enough, your phone will be rooted.
There are tons of bootscreens available. Just pick one and place it in /system/media (don't forget to backup old one) with -rw--r--r permissions and Bingo! You have changed your bootscreen.

Try the same app several times. It usually does not succeed in first attempt. It you fail each time, try kingo root with windows software.

Dude, your on latest android version. There isn't any exploit available to root ver 5.1.1
You either need to wait until anyone makes an exploit for your phone or you need downgrade your phone and root it.
There is a pre-rooted firmware available for lollipop But it works only if phone has 5.0.2 .
Unfortunately your phone has 5.1.1 that means you still need to downgrade your phone and flash pre-rooted 5.1.1
Also, your bootloader can't be unlocked. So you need to flash ROM accordingly. Don't ever flash ROM that are meant for unlocked bootloader.

hitman-xda

when someone makes an exploit for my phone and root 5.1.1 . i steel need to unlock the boot loader ?
