[Q][P]Unlocking bootloader on JB - Sony Xperia P, U, Sola, Go

Hey guys so to update to JB I relocked my bootloader and update using SUS. Everything worked fine and i was running JB.
Later I tried to unlock bootloader using Sony's official website. The bootloader was unlocked but I was stuck on the boot animation and it refused to turn on even after 30 minutes!
So now I have again relocked bootloader and repaired using SUS but i want to unlock on bootloader on JB..
Has any one tried unlocking bootloader on JB?

I tried unlocking BL on XGO, and it was giving me errors too.. Can't unlock it and I'm searching for an answer.

Anybody else can confirm that BL can't be unlocked on JB?
I wast just thinking of this because of root but now I'm unsure

I just unlocked my bootloader on JB, and after that I faced the same problem - It got stuck at bootanimation!

Why would you relock your bootloader anyway? Why not just flash a .ftf file using Flashtool?
Isnt it completely useless to relock your bootloader when you will unlock it again later??? i dont get it :silly:

after jb update my bootloader unlock status changed from yes to no,
I am unable to unlock it now, it's their any method to unlock it.

relock bootloader - possible?

Hi there is it possible to relock the boot loader for xperia mini? I unlocked it because i tried CM7. Now I am thinking of going bag to original firmware. Any help is appreciated!
If relocating is not possible, what should one do to get as close as possible back to the original firmware, is it still possible to get official upgrades?
Best,
Thorsten

First, this is ray forum
Second, try here http://forum.xda-developers.com/showthread.php?t=1126358
Third, remember if you are doing it with official method, you will never able to receive FOTA or SEUS update, you can, but only by flashing from xda.
So since we did the unofficial method, After we update through SEUS the bootloader is still unlocked?
I don't know about that. Since the service info still says bootloader unlocking allowed, I think the phone thinks itself as still locked. Flashing from seus might rely more on drm instead of whether the bootloader as locked or not.

when service info says Bootloader unlock allowed: true, that means that it the bootloader is locked, but can be unlocked at will
as many devs say, unlocking the bootloader voids the warranty and bricks the phone when doing FOTA or SEUS
but there's a flashtool out there for us that will take care of it

You do know this method right? http://androidflip.com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working/ When using that method, it is unlocked but the report still says 'Bootloader unlock allowed: true'. So if you use this method (as what idareyou and me were doing back then) the phone thinks that it is still 'locked', even though it's unlocked.

Yeah. I can confirm that my bootloader is unlocked but it still says 'Bootloader unlock allowed:Yes'
I thought at first I wasn't succesful even though it went smoothly so I tried flashing custom Kernel and it was succesful.
I want to know if in the future if SE release their ICS and we update using SEUS the unlocked bootloader remains because believe me, I don't want to go through the same process again, I got electrecuted several time because I don't have test points, just a clip and copper wire.

[METHOD?] Relock the bootloader (unlocked with test point method)

Hey guys.
Two days ago i have flashed back my SK17i to stock rom.
I updated from FOTA.
I didn't know i must relock bootloader before updating from FOTA, so i bricked my phone.
After 2 minutes of deep panic, i've flashed the relock .ftf file, but it won't work on phones unlocked with test point.
So, i found a way to relock bootloader and go back to stock. (On forums i didn't see any guide regarding the method to relock bootloaders unlocked by test point)
I've done in this way:
1) Flashed stock kernel
2) Flash the .ftf relock file
3) With S1Tool hit restore
The phone is now bootloader locked, without losing of DRM!

Did you tried to download the latest version of flashtool?
Also, try to re-download the ftf file from another mirror, you should able to relock bootloader.

brov dont really understand dis, please break it down a little bit!
I just registered to confirm this method works. I foolishly allowed a FOTA yesterday and bricked my phone. It was unlocked via testpoint so the relock method didn't work, even though I tried it! I also tried flashing with S1tool with generic firmware and that didn't work. Then just out of curiousity/desperation I clicked on the RESTORE button in S1 and my phone actually started but was now locked again. I re-did the testpoint unlock this morning so now my phones fully updates and working with my SIM of choice.
I don't know if you need to do all the flashing as it may just be the RESTORE that does the trick. I definitely won't be allowing any OTA from now on. Lesson learned!
Just to confirm, so long as I do the update via PCCompanion or SEUS software I wont need to do all this?
Files to download please?

What files?
If you unlocked your bootloader with test point, no need to flash anything, just press restore button in s1tool.
anyone tried this method to relock the bootloader which unlocked by test point method and still have the sim/network unlock

hey, what is ur method to unlock ur BL via paid version or free?
if free , can you access the fastboot mode??

[Q] I don't know what to believe.

I recently simunlocked my SK17a using Omnius so I went ahead to unlock the bootloader on my phone via the Sony Ericsson Official way and it ended up telling me that it's already unlocked, however, s1tool still gives me a capital R for the loader string and my phone still says "Bootloader Unlock Allowed: yes". I don't know weather to believe Android SDK or s1tool.
Try flashing a custom kernel in fastboot to test... if it works then you have successfully unlocked bootloader and kept DRM...

if you do it properly then there is no chance of bricking it.
flashing a kernel would not work if the bootloader is not unlocked...
I seem to not be able to find a .58 kernel.
Here http://forum.xda-developers.com/showthread.php?t=1398910 try this one it should work with stock rom.
I risked it by flashing CM7. My bootloader is unlocked!
well done!! you can be at ease anyways as there's almost no way you could brick your phone. anyway we are still here if you need any more help!!

[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
Regards,
UchihaDareNial
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

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.

no way of keeping the phone rooted and locking the bootloader?

After flashing this file 'Xperia_U_ST25i_Relock_Bootloader.ftf' to my Xperia_U, the phone won't boot again
I had to flash again with 'ST25i_6.0.B.3.184_O2-CZ.ftf' in order to get the phone working gain
This also made me lose Root, so I had to reflash again with 'Xperia_U_ST25i-ROOT-ROM.img'
(and unlocking again with fastboot.exe -i 0x0fce oem unlock 0xkey)
so, it seems there's no way of keeping the phone rooted and locking the bootloader
(I want to lock the bootloader locked in order to get updated to 184 though PC-Companion)

I own an Xperia S, I flashed a custom kernel to root then flashed back the stock kernel and locked the bootloader again, the phone works perfect and kept the root!

Too keep your phone rooted you need to keep its bootloader unlocked and if you try locking it again you might brick it!!
So if you want to keep your root and bootloader locked then here's what you should do
1)Unlock bootloader
2)Flash a custom kernel which roots your phone
3)Flash with stock rom
Note : if still not rooted then untick the option in flastool to skip flashing kernel when flashing with stock rom!!
Pls correct me if m wrong!!

What I want to keep is:

Then, lock bootloader again, withOUT losing ROOT
and then update to 1.84 (via Companion)

You cannot update via pcc even with Locked BL if you have custom rom or kernel.
