he helped me last night,have same problem and now i have unlocked phone

After getting an Unlock code from TMO..

after i input the unlock code (sim unlock) from tmo, can i do a full factory reset? in other words, will the phone still be unlocked after a full factory reset or do i do the reset first and then input the unlock code?
thank you!

Yes, Once it is unlocked it is unlocked. You can factory reset, flash custom roms, odin back to stock. You will not loose the unlock.

Yeah your good dude like the other guy said once its unlocked the settings are saved deep inside the phones system so u can flash custom roms and all that

ok i have another question real quick.. do i need an active sim card to unlock the phone or not??

Arc S 12W22 bootloader

My phone is manufactured in 12W22, is there ANY way to unlock the bootloader? It's a carrier branded phone (got it as a gift)

It is unlockable but you need to remove the carrier branding first.

Any Arc manufactured after 12W11 will have a bootloader that cannot be unlocked. You can try wotanserver for the debranding but not sure if you can unlock your bootloader.

Mine's LT18a 12W15, perfectly unlocked and running JB so.. I'd tell him to give it a shot.

Of course, that number could be just a rumor, no harm trying it.

Hi mine is an Arc is network unlock as its an orange one and I'm using Vodafone. The numbers on it are 11W12 and I filled the thing in on Sony boot loader site and they've sent me a code.
I've rooted it already but it says in the service menu it says the bootloader can't be unlocked.
Mines an LT15i but it now says its Lt18i
What's right can it be unlocked or not?

I understand you came from Samsung... I also used Samsung myself back then and experimented with the root and everything.
Rooted a S3 back then which had the "recovery-from-boot.p" script that did not allow me to flash CWM recovery on it.

Wrong, official method still works for non-SIM locked phones. Branding has no effect at all.

As I already said, it does not matter, if phone has branded firmware or not. It has nothing to do with bootloader unlocking.
If the fastboot is disabled, then you can not do anything. This mostly occurs, when phone is SIM-locked.
If the fastboot is enabled, then you can use official method at unlockbootloader.sonymobile.com.
To see, if fastboot is enabled or disabled, just try entering it - Turn off the phone, hold down Menu button, connect USB cable. If blue LED lights up and stays on, fastboot is enabled and you can use the official method.

I can't enter fastboot, my phone is sim-locked. I think that I could get the unlock code from my carrier, would that make any difference?

Unfortunately, no. This does still not enable fastboot. Fastboot can be enabled only via test point method, but due to newer security systems, this is not possible on phones manufactured after 12W11.
So, unfortunately, you are one of the unlucky ones, who have to deal with locked bootloader. For now. Until a method is found, that can bypass the newer security standards.

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).

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,

Factory Resetting a Carrier unlocked phone

If I Factory reset a carrier unlocked t-mobile S8+, will I have to unlock it again? Does factory resetting affect the carrier lock?
