How to unlock boot loader - SE ARC S???

Im trying to unlock bootloader of my SE Xperia ARC S, using instruction from unlockbootloader.sonyericsson but problem is because I can't do everything like is described, because there is some error "FAILED (remote: oem unlock failed)
Softare version: 1253-8238_4.0.2.a.0.62
S1 boot ver: 1241-3656 r9b030
Model: lt18i
Is there anybody who can explain step by step process for unlocking boot loader on ARC S?
Thanks in advance...

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:

Works unlock (not pemanent) on galaxy nexus gsm vodafone

Docomo App
Yes Sorted!

N wifi does not work after flash
Sorry - found out why the N WiFi was not working. It was my SIM card! I used a balked SIM card for testing but when I put in the working SIM card the WiFi N worked. ... go figure.
Ran the ****docomo.apk on the SC-04D Galaxy Nexus.
First let me go over the general experience then I will go over the problem
It works. It makes a back up of your IMEI data when you choose either permanent unlock or temporary unlock. You have to restart the phone for the backup folder to appear. Once your phone restarts you will see a folder called .unlock_backup. You should copy this to a safe place on your computer.
The phone unlocked in both unlock states. Worked with T-moble and sofbank.
I ran both the permanent and the temporary unlock. flashed the ROM both times to test. The lock reappears with the temporary unlock but does not reappear with the permanent unlock. (Just as advertised) Resting the phone erases the backup folder on the phone.
After the flash I checked the IMEI number and it was completely different from the original IMEI number. (Permanent Unlock)
I reinstalled ****docomo and then copied the .unlock_backup folder from my computer back to the phone. After restarting the phone it could see the backup folder again. I could re-lock my phone and get the original IMEI working.

Great!
works perfect... thank you so much

Does this apps work on other simlocks?

Any plans to update this for the new update? I heard it doesn't work with the new 4.0.4.
Sent from my Galaxy Nexus using XDA

app doesn't work on 4.0.4, update soon?

4.0.4
The unlock temporary option does not work on 4.0.4 but the unlock forever does work.
If is no downside or risk in this option wich mess up the imei I think i gone to leave it like this.

Yes, the app doesn't work anymore on 4.0.4 to do a temp unlock so I decided to use a perm unlock. Also, found this thread http://forum.xda-developers.com/showthread.php?t=1570342 to maybe temporary fixed the generic imei.

What does this apk do with the "full internet access" permission it requests?

Need Help to install ruu or rom to unlock SIM Sprint htc one M& Kardan

Hi,
I bought brand new inactivated sprint htc one m8 harman kardon. I managed to get it bootloader unlocked, S-Off, rooted, and TRWP 2.7.0.2. I'm trying to get the SIM unlocked but I couldn't. I used the following method to unlock the sim but I couldn't pass step 4 as I reach to hit "start" but nothing happens. (http://forum.xda-developers.com/showthread.php?t=2718150&page=5)
I also tried to install roms but when the mobile boot after I get successful installation, it reboots on bootloader screen only.
I appreciate any help.
Thanks.

you do realize that post you linked to right at the top it says 100% works from GSM unlocks. nowhere does it say anything about CDMA phones...? which your sprint model is...
and yes i know what your going to say it has a GSM sim card slot but it doesnt matter.
when people say compatible with GSM models it mostly means international GSM and US(ATT/TMOBILE) phones. CDMA phones are a bit more complicated. cause theres the extra CDMA radio partition.

you dont need to unlock the SIM in order to use custom roms. all you need is to unlock the bootloader using the HTC unlocker

I did unlock the bootloader in addition to S-Off. However, I'm not able to install any rom. After I try to install the rom (zip file) and I get the message to rebbot after I get successful installation, it boots back to bootloader screen!

Unlockable Bootloader?

Anyone hear anything on this yet?

Haha you have been a little bit faster than me xD Would have been my question as well, are there any information about this?

Razer already stated it would be an unlocked bootloader. Can't find video but it's mentioned in one of the first hands on

To me, that sounds more like that it is going to be unlockable but it won't shipped unlocked.

I saw somewhere the bootloader can be unlocked via the developer options menu? iirc In a menu though..

It ships _carrier unlocked_ (sim).
Bootloader is unlocked by the user in dev options on the phone, should the user so choose to do so. Voids the warranty.
Rooting the phone is up to the user, but also voids the warranty, as the reply in the image says.

There will maybe a option to enable unlocking the bootloader.
This will not unlock the bootloader, it will only enable the command to unlock it I think.
Like on the oneplus.

If you live in the EU, unlocking the bootloader and rooting the phone - wont void the warranty, if you have a hardware related fault.

I do find the EU has better consumer protection than the US.
What companies can do here while taking your money? Uh ya, that's one reason I bet the USA is becoming a big laughing stock of the world.

YMMV But from what I've seen with a few other companies, if the repair is hardware related and not software they almost never actually care if its bootloader locked or not. Can't say Razer/Nextbit would be the same though.

Ya I've not dealt with razer for the laptops. I know for my mouse and keyboard record, they're good on responding, synapse updates happen fast enough to almost be annoying, hardware seems decent, though about 20% fails after the first year. (though I found out later the mouse doesn't actually fail, it's electric "char" that builds up on the metal switch internally because it's so thin)
Got the phone otw though, pretty excited. Can't wait for the analytics to start trickling in to see what we can do with this beast.

I have one already. It works. Just tried it. Bootloader unlocked.

Sweet! Thanks for uploading this.
Now if we can figure out how to root it while we wait for a TWRP Port.
Looks like all we need is a copy of the boot.img. Then we can patch it using Magisk.

That's not how you unlock the bootloader, that setting is part of the process and enables the ability for you to unlock the bootloader via fastboot.
I've made a thread on how to unlock the bootloader and linked it below

You would not be able to select that option if the bootloader was unable to be unlocked. It unlocks the first key. If that key is unlocked, then fastboot oem unlock bootloader can work. So it is valid proof that it's unlockable.

Right, I didn't dispute that but he said "Bootloader unlocked" which at that point, it was not. If it was, that setting would be greyed out and it would say "Bootloader is already unlocked"

The three questions I asked when the phone was announced, and finally weeks later they are answered

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

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
