[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.

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.

Fudge, I should have read a little longer ...

First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the dialler and enter *#*#7378423#*#* to access the service menu.
In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

Hi, I get the same error as omar-su. I have checked my service menu and it says "Yes" on the bl unlock state. I also followed this step-by-step tutorial exactly. Has anyone else experienced the same problem?

Try booting a custom kernel by this code.
Fastboot boot boot.img
Where boot.img is the name of the kernel.

Ey bro!! Can you please tell me how you fixed it?? I have the same problem to do it ;confused:

Hi it's been a while since i've had my arc. But when flashing any kernel you must flash it as boot.img through fastboot. As a safety measure i always have a stock rom downloaded in case of any errors so you should download a matching Tft rom to yours. Have a look at some roms you want to try and see what kernel will suit you best as they are all different. Hope this helps.

Please help

[Q] How to root sony arc 2.3.4 0.62

Hi all,
I'm new at android devices and i have bought a sony arc phone for days.
I have flash my Arc in android 2.3.4 and unlocked bootloader.

I do gooling and find many ways to root but it do not work for my case.
I found that there're two best ways:
- Do flash back to 2.3.4 .042 and do rooted , then update via wifi to 2.3.4. .062. I have unlock bootloader then i think that i can not try this way.
- Other way, Go to fastboot mode and then enter recovery section, try to update rootPhone.zip . But when i enter fastboot command it say that you have to rooted your phone first!!!
What should i do now ? I don't want to go for ICS because of battery's time.
Anyone can have suggestion for me.
Thanks,

the only method is that unlock bootloader

hi roy56120, thanks for your comment.
But i think that you do not read my post, i have unlocked bootloader, but when i try to enter command in fastboot.exe folder , it say that i have to root phone first. Damn, I need fastboot to root but it requires me to roots first???

Fastboot doesn't require rooted phone. You need unlocked bootloader and correct drivers.
You can also relock bootloader and then make OTA update.

dude, i have read all the thread you post. It actually does not go with my case.
arcording to those threads, I found only one way to root on my arc, re-lock bootloader and do root on 2.3.4 .042
But, the thing is, my arc can not re-lock bootloader :-S because of the method to unlock

Then flash back to .42 and try again.
