[Q] relock possible ?

Hi, is it possible at today to relock the boot loader and reinstall the original firmware of the phone

You can install original software, but not relock.

mmmh ... seems i can not reinstall original software from SE Update Service anymore after bootloader unlock ... it tells me 'the telephone contains modified software that can not be upgraded' ...

the only option u hav after u unlocked the bootloader is to update through fastboot..

or FlashTool .

question: if i just unlock the bootloader i can't use SEUS ????
thanks

Precisely.

I think I saw a UK SE facebook guy replied that updating the firmware is only supported for unmodified software even if you have unlocked the phone...
the thing that I'm not sure about is if you modified the software, then used FlashTool to flash the original stock software... will this be enough to use SEUS ? or using SEUS is not supported at all after unlocking ?
I'm wondering this as this is my only concern... I don't care about DRM, but I do care about using SEUS to update rather than manually waiting for the updated stock image and flash it using FlashTool

Well, whoever that guy is, he was wrong.
After unlocking my bootloader but before rooting or anything else, I tried connecting my handset to SEUS but got an error message.

once u unlocked the bootloader, u cant update the firmware through pc companion or seus, period..

Maybe they don't know, or maybe SE needs to update SEUS

Motorola's facebook account claimed there were going to try and develop a bootloader unlocking system for developer customers, that never happened.
The people manning these accounts are peons, or possibly not even direct SE employees, they may work for some sort of PR agency or similar.
So I for one am not at all surprised they don't know what they're talking about.

They do work for a PR agency.. however.. they provide technical advice.. and my question was a direct one, to which they gave a direct answer.. and if I can't upgrade using SEUS then I'll be getting them to fix, either SEUS, or my phone!

Try doing "fastboot oem lock", that should work.
Or the same command as with the unlocking, that means including your key, but replacing "unlock" with "lock".
EDIT:
It seems they those two don't work. I'll try a little more later today.

It takes more time than I thought, it's much more complicated than I expected. Anyway, I asked a friend of my at SE about it, he'll ask about this on his work

Why nobody know to relock bootloader yet?

http://forum.xda-developers.com/showpost.php?p=13976687&postcount=39
Guess that's a more accurate answer than on FB. ;-)

Why are you so worried about SEUS? FlashTool does the same thing as SEUS...
BTW, bootloader lock state and fastboot flag are in TA Misc. I still have to find out where exactly...

Yes i can use flashtool but the original firmware when they come out, I can install them immediatly and also for the discussion of the warranty

Only sim unlocked phones can use the sony bootloader unlock service, you will have to pay one of the people here for a remote unlock if you want sim/bootloader unlocked.

Thank you.

Just a nother quick question...
since i have a 4G AT&T xperia play i can acctually unloack the bootloader and by re-flashing the ROM actually preform a SIM unlocking like it discribed here: http://forum.xda-developers.com/showthread.php?t=1034371
????
will this work on my AT&T 4G device ?

Nope, this link is for sim unlocked phones
I'm gonna use Alejandrissimo in the general forum to unlock my phone tonight...

ok ... so just to make sure i got it right:
1. i need to first unlock my sim
2. i will be able than to unlock the bootloader
?
did i got it right ? since this is actually collides with what i'm reading here:
http://forum.xda-developers.com/showthread.php?t=1349669
[astralmaze05]: ok i understand, if i sim unlock it using the online unlocking services will it also unlock my bootloader automatically?
[Logseman]: No. However, the contrary is true: if you pay to unlock your bootloader your Sim lock will vanish as well.
Click to expand...

Here you see that it was said that unlocking the SIM doesn't mean that you can unlock the bootload...
any response ?

I insist: unlocking your sim won't unlock your bootloader, you will have to unlock it separately.
However, unlocking the bootloader automatically sim-unlocks the phone.
Thus, save yourself the grief, contact any of the unlockers mentioned in the thread of my signature, and just unlock the bootloader.

I will since i'm seeing it getting more complex then i wanted.
but still i want just to understand if unlocking your sim won't unlock the bootloader but, after the sim is unloacked then i could use the bootload unloacker online from sony, no?

No, you can't. The official Sony bootloader unlocking method is only valid for phones which were sold originally Sim-unlocked. Sim-unlocking an originally Sim locked phone will not make you eligible for the Sony bootloader unlocking method, so you would have to use Alejandrissimo's bootloader unlock method anyway.

Thank you ! now i got it!
i hope this thread will be a good use for others as well.

No matter what you do, you can NEVER use the official bootloader unlocker.

I would like to thank Alejandrissimo for his quick and working unlocking method from remote!!! works wonderful!!!

I just used this service...
http://www.cellunlocker.net/sony-ericsson-unlock.php
Make sure you have another SIM Card that is different from your service provider. Only $7.99, thought it was a good deal.
Edit:
Fudge, I should have read a little longer ...

Because Im askin for little help and step by step guide from people who mastered that, from this forum.

Oh, OK then. Your phone doesn't have an unlockable bootloader because it's SIM locked to a network provider.
You can unlock it unofficially for a few bucks.

It's the unofficial testpoint method.
Contact someone like Jinx13 for it.

You CAN unlock it -- just not for free.
SIM/network lock:
[Dialer] > *#*#SERVICE#*#* > Service Info > SIM lock
- Network
- SIM
0 = unlocked, 1 or otherwise = locked.
Paid bootloader unlocking also SIM/network unlocks, as shown in the video above.

In case if your phone is NOT sim-locked,try this :
check your IMEI number,if it starts with 0 (zero) then you MUST enter 0 while typing your IMEI number at SE site while getting your unlock code.
EX: IMEI no. is 012342565325431 then you must start from 01234256532543 and ignore the last digit.Then,you will get a code which when entered,will unlock your bootloader.

I have the phone ARC S LT18i and my phone says in the Service Mode:
"Bootloader unlock allowed: no"
Is there anywhere a tutorial how I can get a unlocked bootloader, or it is not possible to unlock?

The solution is in that thread:

If you did it right and its still not working it's not software problem but last try flash it with Sony PC companion..... if it still not work it maybe a hardware problem... Get it repaired....

Unfortunately no. Hidden menu only has test and reset menu items with zvd same as zvc.
Any with ebay unlock able to get LTE speeds with zvd now?

Are you guys sure I can update without getting it locked again

I'm not sure, but i asked an ebay unlocker about ZVD and he said it's currently un-unlockable.
so be very careful.
I'd suggest turning off auto updates in developer options (setting>about phone>tap build number like 7 times)
I also called sprint about jacking up my phone. They will not unlock (even if it was previously unlocked domestic and international) if the phone was on their network less than 50 days. If the phone was on their network longer... then maybe... but no guarantees. They were extremely unhelpful. :silly:

Please elementdgp did you also unlock your phone using remote unlock from EBay.

Thats why I tell people dont update stick with the lowest possible and you normally dont have the issues.....
Are the updates more important that risking the unlockablility of your device? Thats the Question to be asked....

I tested this update (statistics and personally).
This update returns the excellent work of GPS satellites (I did not even see it at all) and DO NOT remove the unlock.
It can be put on the ZVC with unlock. It can not be put on the ZVC without an unlock or VZB. If you unlock the remotely (Octoplus) - the update is safe! I checked the axiom on 8 people + myself.

So did you unlock using remote unlock from EBay. And when you updated it didn't lock

kleinkel said:

Click to expand...

Yes. ZVD not remove ZVC unlock (octoplus), but if unlock was not installed on early firmware (ZVB, ZVS), it will not let you install a new unlock. Octoplus not support ZVD native.
Update with unlocking ZVC - approve
Update with ZVC without remote unlock or ZVB - you can not !
This is minor update - It does not overwrite the area where the unlock is stored. But this update animates GPS satellites, if you have problems with them and improves autofocus cameras on the stock camera.

Thanks a lot

But has anyone else confirmed it

I just updated it and it didn't lock my phone
