Relock Bootloader on Xperia Arc and get Back SE WARRANTY ?

Hi Guys
i have the famous front cover brake.
My phone goes to the Service CEnter from Se here in Germany
and they said that i changed the Firmware so the warranty isnt anymore available.
Now i have only unlock the Bootloader and rooted my phone.
Now i have relocked the Bootloader and flashed the stocl 2.3.4 FW on it.
Should i try to resend it to the Service Center ?
or will they still recognize that i unlocked the bootloader ?

They probably won't even notice, btw u meant "front cover break"? The stupid crack near the sensor?
If yes i think its said in that thread that issue it is covered by warranty.

When you unlock the bootloader, you provide to Sony Ericsson the IMEI code of your telephone. I think if you send it again to the Service Center they *might* check in a database if that IMEI has been provided in past to unlock the device... this is why at the moment I prefer not to root (and so not to unlock bl) my Arc s.

yes but they dont want do accept the Warranty
They say that if i unlock the bootloader (and i have done this)
the Warranty is anymore available

And It's said during the unlock procedure that the warranty will be void... at least the official SE procedure...

For hardware issues I don't think we will have that issue. Unlocking Bootloader and Hardware issue is not really related unless we bricking by flash ROM or something.

If u got warranty pls update this post.that will help others.thanks in advance

I read that this warranty is avoid only for SOFTWARE SUPPORT.
Following the law, they should keep in charge all material problem.

It is not possible. As you can see in official instructions, last step:
Code:
Warning! If you perform this step, you will unlock the boot loader and which may void your warranty and/or any warranty from your carrier.
So you void warranty only if you physically unlock your bootloader and perform last step. So requesting unlock code SHOULDN'T void warranty.

Getting an unlock code doesn't mean that you should have unlocked it...it gives you the option. That's it

I got a glossy black brick... I think.

Hi everyone, on this past week I've been trying to get me XP back to life... but with no success.
For starters I woke up one day to find that my phone has powered off by itself (no root nor unlocked bootloader), tried to power it on but no response, had to remove e reinsert the battery for it to boot up. Some days later same thing but when i turned it on it started a bootloop, repaired with SEUS.
This week it made the same thing and i had to repair it with Wotanserver, but when i let it alone it would reboot... everytime it entered the sleep mode it would crash and reboot. Tried flashing some roms on the forum with no luck... now wotan sees my phone as a R800i when it really is a R800a and SEUS keep saying that me phone have the latest update.
Yesterday it stopped bootlooping... it don't even show the "Sony Ericcson" phrase.
I'm new to android phones got this phone in oct/2011, didn't installed CWM.
So if someone could try to help me i would really apreciate.

Ok so, download flashtool and flash the latest r800i firmware or the any r800a firmware. As long as you can enter flash mode, your phone is fine. The reason the roms didn't work is your locked bootloader.

Nevermind, Potato13 beat me to it before I finished typing.

Thanks for the replies.
Yes I tried flashtool with several rom's either R800i and R800a from .42 to .62, from US to HK. Neither made my phone show any signs of beeing better.

try to unlock your bootloader.. then flash r800a fw..

So to get this right - You already flashed different stock firmwares to it and that stuff still happened?
Should actually not happen... to me that would indicate that there is some kind of hardware problem since you never rooted the phone nor unlocked the bootloader to really mess things up.
I would send it in

Isn't unlocking bootloader only for custom rom's? Well thats what i think it is.

Yes I was thinking on doing so but i already flashed other Fw's on this phone isnt my warrant already void? I'm saying this because I dont think I would have the money to pay the repair service.

As far as I am concerned, only rooting and unlocking the bootloader voids your warranty. You have done neither so you should be fine .
I asked Sony Customer support once how to handle my not booting phone and they adviced me to flash stock firmware - So I would figure they can't deny you services because of doing so.

Ohh I see thanks for the answer, really appreciate.

Sent the phone to SE as sashake recommended, and turn out that the problem was with the hardware itself.
SE gave me a new unit as it was still covered by warranty.

[Q] A way to unlock the bootloader?

i heard that it isn't possible to unlock the bootloader after the date 12w11.. mine is built in 12w36 so no way to unlock the bootloader.
if i use this video (unlocking via testpoint) it works? Because in description is standing if there is standing bootloader unlock allowed: no you have to root it at first!?
mine is rooted and there is still standing no so can i unlock my phone with testpoint!?
A friend has the xperia arc (lt15i) and a guy from Handybörse (so it's called in germany) unlocked his bootloader but at phone were standing 12w24 !?
i dont know how he unlocked it but it works and before there were standing no and now there is standing yes??
So i can unlock my lt18i with this video (sorry its in german but i think everybody know what this programm is and what it means)??
Thank you guys
Hope for fast answers!!

Phone after 12W11 can be unlocked via official method only, cannot be unlocked via testpoint.

ok, but mine is 12w36 and i cannot unlock by official method..
so if i cancle the sim/netlock it is able to unlock it?
because i have bought my smartphone by 3 (provider in austria) and there is a branding and sim/netlock.

No, you are one of the unlucky ones, who can not unlock bootloader at all.
Removing sim-lock/branding does not allow you to unlock your phone, because fastboot is disabled and only way to enable is via test point method, which is impossible at the moment for the phones manufactured 12W11.

ohhhhhh...
but it worked at the arc from a friend...
there was standing unlock allowed no and he disabled sim/netlock and there stand bootloader unlock allowed yes..
manufactor at 12w14 :/
so i dont know

Mine is also after 12w11 and I unlocked official but I had a badblock @Sahaab also couldn't unlock his bootloader so dude face we are stuck with a locked bootloader if you want a newer android version buy a more recent phone

the bootloader isnt the problem. but i want to flash any kernel to overclock my phone. but i think this isnt possible on my device so ill forget it. i dont want a better android version. i only want to use my gingerbread roms faster and use all of them. thats why..
im happy enough if i can flash kernel

But to flash custom kernel, you need to unlock your boot loader, which is impossible unless you get rid of the carrier lock.

[Q] Unlock bootloader if Allowed=No for Z1C

Hi there,
I have a network unlocked Z1C which came from o2. The bootloader unlock allowed status is No but the phone is rooted. Is there anything I can do to this to unlock it? I feel like trying CM on it
Thanks!

If your bootloader unlock allowed status is no then you will most likely never be able to unlock that phones bootloader. I think your best bet is to contact O2 and tell them you want a phone on which the bootloader is unlockable, perhaps they can give you a special key to unlock the functionality, but I wouldn't hold my breath.
Oh and don't try CM on it, it'll just bootloop and you'll have to use SUS or PC Companion to restore a working OS.
...actually there is one hope, but it requires dismantling the phone. There is a test-point behind the battery which might enable you to put the device into a mode where it'll accept a command allowing bootloader unlock. But again, high risk, not sure if it's actually possible, easier to just sell the phone and buy an unlockable one if you want to run CM. Maybe you could even return the device, how long have you had it?

my z1c just turned up and ive got an bootloader unlock allowed :victory::victory::victory:

I have locked bootloader on EE in UK and have found that many of the tweaks I wanted can be achieved with Xposed modules. Give it a try but backup before you start.

Need a opinion by a dev
Hello there,
I was thinking about a test.
My problem is "Unlock bootloader allowed : no".
What could happen if i restore an other TA partition with "Unlock bootloader allowed : yes". I erase the old by a new one which unlockable. All i need is a TA partition build with a z1c which unlockable and the unlock code.
What do you think ?
Soory for my bad english

If you replace your ta partition it will most likely hardbrick your device.

What is a ta partition, i don't understand.
A bootloader is like a bios on motherboard.
But it is locked by a code.
The bootloader is the same on each z1c no ?

Flashing another phone's TA will hard brick yours, every TA is related to the phone which comes from

You will never be able to unlock the bootloader on that phone, unless your carrier can give you some kind of code to change your unlock status (not sure this is even possible).

I can get the unlock code not a problem to unlock phone to any network. am already waiting for that from o2 so can use on any network but will this work or is it a septate code that is used for bootloader or somthing

The BL is different, if it came from O2 then chances are you cant unlock the BL.

So there is no chance? It worked with xperia arc and omnius. Costs about 15$, that would be ok. But will it work with our z1c in the near future? Or is it just "luck" to find an exploit?

Well nothing is impossible, but it isn't likely as it requires a bootloader exploit. Realistically it isn't going to happen though, unless some smart people devote a lot of time to it. The most likely scenario (using test point to gain more software access) would require hardware tampering.

Hello Mentalghost,
Unfortunately there is no way to unlock the bootloader when the status is "No".
Have a great day, cheers!

MentalGhost, where did you purchase your phone? This phone isn't sold by any carriers in the USA, to the best of my knowledge, so the bootloader shouldn't be locked.

Bought in UK where I am not in USA. Might take back to shop where bought from and see if got any others in lol
Or wait for locked bootloader versions or someone makes modded version with unlocked rom that is been modded like one where you install modded that is unlocked install and then can unlock bootloader did in xperia s I use to have was a modded rom that was originally saying bootloader unlock no and added new Base rom and then said bootloadr unlock yes maybe this will happen on this phone in time or locked bootloader kernels and rom come along

I'd recommend to anyone that is still able to return a Phone to do so because I think you'll find you'll be waiting a long time for a solution.

Plus, there will be no solution. The reason why Xperia Arc S and other 2011 Xperias worked with testpoint method was because of that there was a big security flaw in the security of the testpoints nand access, but those flaws have been fixed in newer Xperias and newer 2011 Xperias also.

+1 It was coming to that realization that I sold my O2 locked Z after 6 months to buy an unbranded Z1 Compact. It worked out cheaper too spending hundreds of pounds up front for my Phone with the added bonus of having access to all of it.

What happens if you still follow the instructions on how to do it? I didn't check if it was allowed and I'm stuck in bootloop and I can't flash via flashtool,
