Do I need to relock bootloader to update through PC Companion? - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

I'm willing to unlock the bootloader of my WT19, so I can flash a custom kernel and install this ROM.
What if I want to update to Sony's official Android 4.0 firmware (when it's released in 2~3 months)? Can I just use PC Companion to restore my phone? Do I need to firstly relock the bootloader to be able to use PC Companion?
Thanks.

havent actually tried it yet, but definitely it is advisable to relock boot loader if you are going to use official update from Sony using their methods.
flashing the official rom using flashtool, if someone uploads it, is possible even without relocking of bootloader.

[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.

[Q] Help with my Xperia Mini Pro bootloader :)

So,I've rooted and unlock its bootloader for a long time.I also install my phone ClockWorkMod Recovery and etc. other root stuff (My android is 2.3.4 .58 Firmware)
So,today I thought I will finally relock my bootloader as my phone will receive a new ICS official from Sony Ericsson anytime from now until end of June,so I download a relock bootloader ftf file (I've searched it in the internet,and download the right file).After I flashed it (I've enabled USB debugging before shut down my phone and I also sure my phone is in flash mode during flash),my phone WON'T boot up...I don't know what happen,so I'm currently fixing it by using WotanServer,and it downloading in progress now (My x10 Mini Pro bricked 5 times,and I fix it 5 times by myself without whining )
So,I wanna ask you guys :
Why my phone won't boot up?Although the bootloader is locked by Flashtool,but it won't boot up I've stock FIRMWARE and stock KERNEL in my phone...never modified it,only root,unlock its bootloader and flash CWM in it...
Thanks for reading I hope you can answer my question

Uhm, since WotanServer installs also stock kernel back...doesn't it require unlocked bootloader?
I am not sure, but that would make sense with all other kernel installations also.
Unlock bootloader, install firmware and kernel with WotanServer again, boot and relock bootloader.

Thanks for the information man,by the way,I just restore my phone using WotanServer and WotanServer will always be my trust to restore my phone if it got a brick or something like that
I restore my phone with Firmware .58 and I rooted it using ZergRush,and update it using OTA [My phone automatically bootloader locked] (I install US Generic xD even I live in Malaysia,so I got Sk17a instead of Sk17i) and now I got .62 firmware with root access in my phone

I think not as pc companion don't require unlocked bootloader to flash the rom.

Yep,you are right...
Because,WotanServer and PC Companion and SEUS use OTHER method which I (even other ROM developer maybe?) don't know how the file work with the flashing without needed bootloader unlocked right?

PC Companion doesn't work with unlocked bootloader at all.
You might be correct, as I have never tried update/repair via PC Companion.

I know, the point is that it's not necessary for flashing stock kernel bootloader to be unlocked.I think it's pretty obvious, if it didn't update with locked bootloader then sony would have to force users to unlock bootloader or give unlocked phones or never update kernel.

[Q] Upgrade to .75/.76 - Future ICS

Hello,
PC Companion says that i have a new update, but i've unlocked and rooted my phone, so when the install should begin, an error pops up saying that i have a modded firmware and i cannot update it.
So, i think the same issue will go on when next week or next year ICS will be released.
The question is: what i have to do to update my XS? I've to flash the ftf loosing the recovery and then reinstall it? Doing that, i will lost all the apps and everything on my phone?
Thank You very much
If you have unlocked bootloader, you cannot update using the official method, but only through flashtool.
If for some reason you want to use the official way, you should relock the bootloader, here is the guide http://forum.xda-developers.com/showthread.php?t=1527159
As far as my knowledge goes: You could backup your apps, lock your bootloader, upgrade to ICS, unlock bootloader, achieve root, restore apps. You'll probably have to wait for root for ICS though, shouldn't take long at all.
Or at least that's how I hope it will work.
So, the faster way is to wait for a custom rom correctly packed to be flashed via recovery
Thank guys

Big questions!

Hi and sorry for my bad English :S
Actually on my Xperia Mini Pro SK17i I mounted the RealICS 4.1 but I would see the official 4.0.4! I have unlocked bootloader but I have a big problem: I can't flash with Flashtool because It always return me an error when It's flashing the system!
Can I flash the official 4.0.4 with PC Companion or Sony Mac Bridge? (I have a Mac!)
What will I do if the flash give me an error? I'm confused...
After that can I lock my bootloader? I unlocked that with the testpoint metod :S
PS: Can i flash this (http://forum.xda-developers.com/showthread.php?t=1772120) on my RealICS 4.1 or Can i have the notification on the lockscreen like in Gingerbread?
Thanks thanks thanks at all :laugh:
What error does Flashtool give?
You need to install the drivers and make sure your phone is in flashmode.
It has always worked and I have everything installed correctly
It give me "Flashing aborted. Error flashing system.sin"
With all the official ROM!!!

Try another computer:good:
Or lock your bootloader & use SUS:good:
I can't use another computer
How I lock my bootloader with the testpoint metod? Should I search into the forum?
PS: my principal question is: "What will do if I use "repair" of PC Companion or Mac Bridge?

It may brick ur device...!!
If you unlocked it via test point, you should be able to use PC Companion without relocking it.
Can I use the function repair of PC Companion or I brick my phone? I don't understand

means using repair on an unlocked device will brick your phone so if you want to flash official firmware and you have unlocked your boot loader then first lock your boot loader by following this method http://forum.xda-developers.com/showthread.php?t=1324703 and then update to latest official firmware
Incorrect to all of this.
If you unlocked via official method,
Installation will not start at all! Update Service/PC Companion can see if you're bootloader is unlocked via official method or not. If it is, you just get error and software won't be edited at all. Relocking bootloader allows the installation to continue, so relock if you want to repair/update with PC.
If you unlocked via test point method,
Installation will work and your device won't get bricked!
Now, solution to your Flashtool - What version are you using of Flashtool? Were you able to install THAT firmware earlier also to your phone?

Just remember this, do not try to update OTA if you have unlocked boot-loader by any method. It will (might) brick your phone. (That's an actual brick. You will need to use un-bricking ftf to repair phone)
Known Issues:
It is currently not possible to unlock the boot loader for CDMA phones.
Some customers with unlocked boot loaders have experienced problems when they are accepting over the air upgrades (FOTA - Firmware upgrade Over The Air). For customers that have unlocked the boot loader, please do not accept any over the air upgrades.

@someguyfromhell: Change the font of your sig where you advice us to use search button, if possible. It's a bit childish [IMO].
Oh good! I can use the function repair,great!
I used all the Flashtool version and I reinstalled all the driver but nothing. It give me the same error..
I flashed all version of Gingerbread (2.3.3 and 2.3.4.) and also 4.0.4...
Any solutions?
No solutions??? Thanks at all for everything! You're the best!
ip :good:
hmmm...using flashtool, try flashing system.sin only....if you keep getting error then flash stock kernel first before flashing your phone again....
See This
See the Attached Picture
I have taken it from sony forums a long time ago ,and tested it and it works and my device isn't broken
Now
But now I have the RealICSv5...sure I can't brick my phone? Ok i will do that with Sony Mac Bridge

How to put stock sony fw back on phone

I think/hope this might be an easy question.
I have an xperia S that has bootloader unlocked and currently running a custom rom. In the next few weeks I may be swapping the phone with a family member. How would I go about getting the phone back on stock Sony firmware. I am not bothered about relocking the bootloader but I want to be able to put stock sony fw back on the phone so that they would be able to update the phone officially via sony pc companion.
it's a bit as I can flash roms /kernels and unlock bootloaders on these things but have now idea how to get it back to stock
cheers

You can reflash the stock ROM with flashtool. In order to get updates via PC Companion again, you need to relock your bootloader.
