[Q] Trying to recover warranty - Sony Ericsson XPERIA X10 Mini

Hello,
I am using a X10 Mini Pro (u20i). I am having problems with my mobile earphone, and since I checked forums and asked SE technical service and they told me that I had to send it because it was a hardware problem.
My mobile is still in the period of warranty, but I rooted it, installed recovery, unlocked bootloader and installed a kernel.
I have SEUS, and I know that I can "repair" my phone to return it to fabric settings, like taking out the root or the kernel.
The problem comes with the bootloader. I know there is an option to relock the bootloader, but I haven't still considered that option.
I was wondering if somebody could tell me if with the use of SEUS the bootloader gets locked again,
Thanks in advance.

If you do a repair with SEUS or PC Companion it will flash the original kernel and rom, but it won't touch your bootloader.
You have to relock that yourself.

i will help you cause i have been searching it too open it conect your phone to flash mode and press restore..... your bootloader was restored

Relock using se tweaker tool.... Its the best..... Be sure before sending to warranty...that the bootloader is locked and ur device is unrooted....

Unlock Bootloader (Hard bricked my x10)

can somebody please help me i just try to unlock the bootloader i followed your instructions. i use the command msm7227_semc.
after i press the button to continue then some text appear and seems to be working then i read some word like rooting, rebooting etc. after the phone starts then it shuts off. that's it i try to turn it on, and remove battery, connect to computer but there's no effect or it does'nt respond anymore. please help me i don't know what to do now. i try to surf the net of what seems to be the problem, someone says that the phone is dead and the only thing to get it work again is to JTAG it. is it true? thanks in advance and i 'm looking forward for your answer.
which method did u use? The developer method or the normal method. and which firmware are you on 2.1 or 2,3
Sir i use the method that posted in the link here:
http://forum.xda-developers.com/showthread.php?t=1254225
i stop on this section because my phone shuts off and i cannot power it on
run msm7227_semc.cmd in the directory you unzipped the unlocking files to and press any key to start the unlocking process. Go to step 5b.
Sir ynkamat i know that you're an experience person on how to unlock bootloader, i already bring my x10 phone to Sony Ericsson service center here in the Philippines Manila. but they told me that they can't repair my phone anymore, because their computer can't detect my phone anymore. and they even don't know the term bootloader so i've decided to bring it to a fly by night cellphone technician and they will Jtag my X10 but in a condition that i'll pay $35 to jtag or repair my phone. i will get my phone tomorrow morning. sir after i get my phone can you please tell me what is the simple and more accurate method to use in order to unlock the bootloader. Thanks in advance and i appreciate all your help.
Hi zerolock1, firstly why did you refer to boot unlocking method of some other phones. The right method is this: http://forum.xda-developers.com/showthread.php?t=1254087
Damn. To be very frank I couldnt unlock my bootloader via this method. So I downgraded my fw from 2.3 to 2.1 and we have a simple one touch tool for unlocking bootloader in the android development section. After that I upgraded back to 2.3 and I am happy to avail benefits of it.
Are u mad u are trying to unlock bootloader with wrong tool and it will brick everytime u are trying to unlock bootloader with x8 tool on x10?
U need this tool and guide here
Never try unlocking bootloader with the tool u tried and got bricked that tool is only for x8!!

Hopeless?
I've done in my X10 and have attempted everything from here I can find. I can't unlock bootloader because it won't flash properly =( Always goes to 99% and fail. PCC, PCC repair, SEUS, Flashtool all fail
Since you're at least seeing the Sony Ericsson logo, there's still hope yet & your phone isn't a true brick (yet!). So you should be able to at the very least flash the 2.3.3 recovery image by DoomLord & get back to stock formware...
Are you sure you have all the proper drivers installed on the system...
problem
I have a problem when I put my x10 into flash mode it says Error in processHeader : 31 : A device attached to the system is not functioning.PLS help me...sry for my bad english
Dude, did u check your phone manufacture date? If it is past 11w29, then u might hardbrick ur phone. Mine is 11w04 and I unlocked bootloader.

Go to dialer and press *#*#service#*#* (service being the numbers 7378423)
Then there a option you can look at which tells you if bootloader is unlocked
Although by the sounds of it, it is
Hit thanks if I helped!

You can try flashing custom kernel via fastboot, and start phone.
About wotan server, you must be doing something wrong, because if you unlocked BL by test point, you can use SEUS, PC companion or wotan server.

[Q] Also no radio after unlocking BL

Hi people, I've unlocked the BootLoader following 9Lukas5's instructions (http://forum.xda-developers.com/showthread.php?t=1254087)
And now I don't have radio anymore.
I checked first with the s1tool and it said "SEMC SIMLOCK CERTIFICATE". I've used the correct bat file and it said that it was unlocked successfully.
It was unlocked because I could install the latest Doom's kernel and Wolf's rom. But I didn't have radio.
I've been searching through the threads looking for answers, but all the methods people suggested, didn't work.
What I've tried: re-locking the bootloader and restauring the phone with seus (still no radio), unlocking again and trying several kernels, basebands and roms (versions 2.1 and 2.3, but still no radio).
Any tips?
Im on the exact same page searched a ton of times this forum and the net and no solution seems to work
Do u know how to check the status of your bootloader?
Sent from my X10S using XDA
I don't think so. How do I do that?
Type *#*#7378423#*#*, go to software info, look at your s1boot version (it will be an r and some numbers) if the r is uppercase (R) it is still locked. If it's a lower case r it has been unlocked
Sent from my X10S using XDA
It has an R..
So the bootloader isn't unlocked? Then how can I use Doom's kernel?
Solution found thanks to all of you guys.
First, use pc companion from sony to restore the mobile. (easy)
Then enable usb debug in the apps menu and with flash tools root the phone, it will restart.
Then with flashtools install the xrecovery (easy)
Again with flashtools in the plugins menu select unlock bootloader and run. Phone will restart a few times, do not unplug usb cable (i was unplugin after the first reboot) and it shall be done
Is it doomkernel for locked bootloader?
Sent from my X10S using XDA
I have radio now. I tried to do what BrixSat said and on the second try it worked
Thanks everyone for your help
i have a similar problem...radio signal of my X10 is so bad and low, when i am at home the signal is 1/4 or 2/4 bar (before was always 3/4 or 4/4).
repair with pc companion or seus did not help me...tried to relock BL, repair with pc companion and unlock BL but the problem still here.
it is antenna problem or software problem?

[Q] Insert sim and restart phone error

Hi,
I recently got my phone unlocked, the person who unlocked it downgraded it to 2.1 and unlocked it, it was working fine at this point.
I updated to 2.3 using SE Companion but I keep getting the message " Please insert sim and restart phone" everytime I boot up.
Would really appreciate some help in sorting this out?
Thanks in advance.
Try repair function in Sony update service. Different software from Sony than pc-companion
THIS MAY RELOCK PHONE. I have never unlocked but have used repair.
