Unlocked bootloader and OTA Updates?

Hey guys had a few problems when modding my cousins Xperia play, I unlocked the bootloader and got it up and running no problems. But I also read if you have an unlocked bootloader you can't update with Over the air updates, is that true, if so, do I have to re-lock the bootloader in order to get them to work?

Yes,u have to re-lock it for OTAs,but using SEUS or PC companion is fine,but u might have to reset the phone.
Cheers

If you update using any method that isn't a manual flash, be prepared to brick the phone. Re-locking the bootloader is possible, but if I were you I would just flash newer firmware.

Thanks for the reply, I was thinking about flashing something newer manually, hopefully it will stop the "there are updates available "messages for my cousin. Wish I didn't bother rooting the phone for him now

Using root explorer or any program that can delete system apps I just delete the mobile care apk and run free

If you're staying on stock ROM or any other stock based ROM, it'll work.
Yes, if you relock your BL and update via PCC/SEUS.

No needed to relock, like some hours after SE release an update, the guys of XDA can release to you the rom.

depends on how you update. i believe that if you update OTA (over the air) then you will retain all apps and root.

But he said that he has Doomkernel which means he is bootloader unlocked. So doing an OTA would obviously brick the phone.

I may be incorrect but I thought that either unlocked via test point you wold still brick your phone if you do an OTA, when I OTA'd this last time a couple months ago I had to re-lock my bootloader, then update, then re-unlock.

Ok. Well that doomkernel wouldn't boot in ics anyway so he would need to fastboot/flashmode stock kernel anyway . Actually when you think about it ics would not be released ota as you would need new kernel and they can only be flashed via pc.

I think they are probably just going to release it via SEUS, cuz I doubt they have any means of updating kernel OTA either

I bought an xperia arc s two days ago..and I want to unlock bootloader/root/install CWM and costume roms..but some friends advised me not to do so and keep on stock status..because thsey claim that I may not be able to update the phone to the supposedly so near almost on the door ICS of android..is it true?and if I did the unlcok bootloader and rooted..won't I be able to revert back to stock and update to the ICS when it comes?what do u think guys..?thx in advance

If u unlock bootloader, u cant update through pc companion. However, u can always relock back the bootloader, allowing you to update using pc companion.
However, in my opinion, having an unlocked bootloader doesnt bring any downside (except losing drm) coz u can still flash ICS using flashtool or flash it as .zip coz the devs at our forum will surely modify it or something...
However,its all up to you

I think it doesnt matter which rom r u on to relock it as long as ur on stock rom. But I recommend using fw .42 to relock cause that was the firmware I usually use to relock.
Im right now using xperia s beta rom 5, doomkernel v19...

I think you can relock any baseband if you unlock the bootloader with the official se method. If you unlock it with a testpoint methode you cant relock it.

Update w/o losing root?

hello.. my current fw is .431 and there is a new update 587
how to install new update w/o losing root?

I believe if you update OTA you can keep root.
For me, I just relocked my bootloader, flashed stock image, used pc companion to update to new firmware, then unlocked bootloader, flashed stock kernel with cwm from old firmware. Then used old root tutorials to get root then flashed my kernel of preference.
Easy right?
Sent from my LT15i using xda premium

it's Easy
if you're on locked bootloader
OTA update will keep your root..,
or if it didn't reach you OTA flash the firmware with flashtool
and it's the same root method for .431 ..,with .587 kernel of course
or if you are with an unlocked bootloader
flash the firmware with flashtool
then flash the advanced kernel .587 ..,you'll find it in the development section
after that flash superuser with CWM from here
hope i helped you =)

^^^^That guy was much more helpful you should thank him

Im sorry.. im newbie.. what is OTA?
Sent from my LT18i using XDA Premium App

OTA is the short form for Over The Air i.e. updating via WiFi or using data on your mobile.

But if you can update via OTA how?
lately on the .431 FW i tried to update it via wifi.. but still it ask me to update it via pc companion.
"You need to plug pc companion in order to update" it says something like that...

but take note that some countries don't have the the new base available via OTA. only method is PC companion.

I have problem updating OTA. When it finishes downloading and I tap install, it reboot the logo appear that is updating but when reboot to home screen it says that could not update. My phone is rooted. I didn't install cwm, only bisybox.

My status:
Code:
- .431 with wotanserver
- Unlocked bootloader using testpoint keeping trackid (Omnius)
- stock firmware + CWM
- Rooted using Superuser
- Some system apps uninstalled.
If I try to update through OTA it makes the first boot and says "Error updating"
What shall I do?
Relock the bootloader? (in this case shall I pay to unlock it again?)
Backup all with titanium, use wotanserver with new version and root again?
Restore all deleted apps and OTA?
Thanks, and sorry, I could not find the proper answer.

To arcuser,
I know what you mean.I tried it as well a couple of days before your first post.Didnt happen.But later in the evening there was a notification from Sony Ericsson via Update Centre on the device that an update was available via WiFi.Clicked on the notification and sweetas iam on build 4.1.B.0.587.
That's the only change that happened and yes the screen comes on faster when you are about to make calls.

Hi!, apart from what you mention, there are more improvements, some of them led notification works better than before, people say it's has less bugs than prior ones.
I've also same trouble, the upgrade is available by OTA but when you download and install it, it reboots and show you an icon and a message indicating it didn't upgraded. It looks that it consider prior installed version and when it upgrades it needs pure sony kernel and rom, otherwise you receive the message. And also, if you do in the other way.. this is upgrade with pc companion you loose your root, so the current solution seems to be going back to . A.0.562 -next to B.0.431 and the root and finally upgrade with OTA b.0.587. This is what people say that works, some guys did it and works, but it is a pain in your but doing all these steps.. so does anyone knows any other way of doing it?
