Good Evening,
Tuesday my Arc will be picked up bye the Post because it have for the second time the Frontcover damage.
Now my question :
I have unlocked the Bootloader and flashed the prerooted.img of the 2.3.4 on the Arc.
Should i flash back to Stock 2.3.4 and close the Bootloader again?
Or will there be no problem ?
Sony Ericsson Germany told me that it would give no problems because the Bootloader is open.
I send the first time the Phone with 2.3.3 and root on it and there was no problem.
Hello, when i unlocked my bootloader and rooted and more i flashed a cyanogenmod rom and send to sony ericsson when i had a problem, they fix and put the stock rom.
I had no problems.
thank you very much

the update bricks the arc when you have a unlocked bootloader, follow the guide in the link i posted and when you fix your phone dont do any more updates until sony have a solution for it
After i unlocked and rooted my arc s, i can't update my phone through sesu. Thus i want to ask that sony arc s bootloader can be relocked now?
I found a thread but it was deleted because of posting in the wrong section.

Just one more question, is there any thing difference between a new phone and a relocked phone? Thank you.
Thank you.
No one ?
Hello, I have been waiting for 1 month
dont know if you can relock bootoloader.
Difrence is that if you unlock bootloader you will never ever be able to have mobile bravia engine, track id and some sort of stuff.
Unlocked bootloader can instal cyanogenMOD (custom ROM, which is powerfull and good)
Locked cant do that, but can recive Sony Updates
Up... same question... we will be able to relock our arc s? Please answer!

I am using a Hong Kong version ARC, bootloader unlocked, flashed customized rom based on stock firmware, and of course rooted. I am going to send to Sony as the gps and wifi got some problems.
Here is my step:
1. Flash original Hong Kong firmware (I don't have it......can anyone give it to me?)
2. Re-lock bootloader
Is the above correct? I know unlocking bootloader should void the warranty, but just have a try to see whether Sony will check my phone or not
I readed that is possible to relock bootloader if you unlocked it by sonyericsson official method for free phones.
For "unlock allowed: NO" I don't know how you can do this, but... Someone said that if you unlocked your bootloader with omnius, you can relock your bootloader recovering the autobackup image that the program generate.
Perhaps you can relock the bootloader first and then do a repair via PC Companion to return to stock HKG firmware.
DRM checking
I think Sony will know your phone status when they check the DRM.
Usually IF you unlocked your phone bootloader by using Sony Method, the DRM also removed.
I followed the step in this website:
http://androidflip.com/re-lock-boot-loader-xperia-arc-step-step-guide/
and my phone can't be turned on now......after pressing the power button, the phone vibrated once(just like usual) and then nothing happened. No button backlight, no screen backlight.........
I'm extremely sorry if its offtopic but I couldn't post it in the development section.
How can we know if the device is rooted or not ?
I used this method

If you used that method and everything went fine, then you're rooted. You should also have SuperUser and Busybox now installed.
Finally and successfully returned my phone to stock status, send to Sony, and get it back after repairing
My method is:
1. reLock boatloader (After doing this you can update it via UpdateService immediately, but as my ROM is an customized 0.62 ROM, UpdateService said I already have the newest software and done nothing)
2. Flash an older version stock ROM (in my case, I flashed 2.3.3 HK version)
3. Use UpdateService again and let it update your ARC to the newest firmware
4. Use root checker and bootloader check method to ensure everything is fine
5. Bring your receipt along with ARC and go to Sony repairing centre
Information not related to the thread
However, I took my ARC to repairing because of the GPS inaccuracy, Wifi disconnection and battery drain. I get it back today and they said they upgrade the software and everything is fine now - I really doubt about this as I already flashed a lot of different ROM (including stock) before but the problems can't be solved. I check the phone information and the firmware is just the normal 0.62 HK stock, no different......

go to service centre tell them that you were doing a 4.3 update and this happened.they wont recognise that your phone has an unlocked bootloader bcoz it doesnt start!they will replace it make sure you dont have cwm installed.

Dear XDA Community,
I have an Xperia M C1905 and I have checked the service info menu and it shows "Rooting Status: Bootloader unlock allowed:Yes" so I can unlock bootloader but I have heard that unlocking bootloader can cause the phone to bootloop. So I want to know how to unlock the bootloader, root this phone and add a custom recovery. I don't know whether I should take a TA Partition backup or not. I do own an xperia SP which I have but it is broken so the Xperia M C1905 will have to be used for the time being. Can someone from the forum show me the right links for unlocking bootloader, root, custom recovery. A set of instructions to follow since looking at the forum I got no idea which guide to follow for this phone.
Currently this phone requires the bootloader to be unlocked without causing a bootloop to happen.
It is currently running android 4.3 stock - Build Number: 15.4.A.1.9
I'm a noob at this since the last time I unlocked bootloader and added custom rom to the xperia SP was like 4 years ago.
Thread closed on OP's request.
Regards
Vatsal.
