[Q] O2 locked PAYG Xperia ARC. Can root solve this?

Hello, i have googled and searched all the threads but to no avail so decided to post another NooB thread!
I bought My arc from O2 on PAYG knowing full well that it was sim locked to this network. Having previously owned a HD2 i thought i could easily install a Open romm on it and it would cure the sim lock on it.
Upon looking into how to go about this i have seen threads on rooting but am unsure weather i will be able to do this on the 02 ROM that is installed on this. is it just a case of following the root guide then finding a general ROM for uk?
to summarise i just want to take the sim lock of so i can put my virgin sim card in and update to the latest android.
Thanks in advance

What happens when you put your Virgin sim in? O2 phones are usually sim-unlocked anyway, but no, rooting or debranding won't remove the lock.

Thanks for the quick reply
It just asks for a sim network unlock pin to enter.
i know i can request this but was told in the shop that i would have to have the phone for a year with O2 before i could do this. I should have just spent 50 pound more and got it sim free. i really thought that i could have worked a way around this though!
Any ideas?

Unfortunately, I have found with the Xperia Arc that it was a pain to get it unlocked. For the Orange San Francisco Android phone, someone at Modaco provided a free app that gives you your unlock code when you type in the IEMI number. Easy. On other phones, you often see codes for sale on auction sites, etc.
With the Arc, it seems it isn't anywhere near that easy or quick. In the end I had to get a refund from one online provider because they couldn't get the code (using their cheaper method - and I wasn't willing to pay for their more expensive service). In the end I used cellunlocker.net for a decent price, but it wasn't a pleasant experience from the point of view of not getting any updates on how long it would take (just kept getting told that it would be soon). However, in the end they did email the code and it did work - it just took about 2 weeks

this is what i found out online for you !!
Welcome to O2. Someone will be with you soon.
You're through to Ashton.
Ashton: Hi I'm Ashton. How can I help?
me: hi , i have a pay and go xperia arc and would like it unlocked , how long do i have to have the phone for and how much would it cost ?
Ashton: You've to use the phone on the O2 network for 12 months and then you can get it unlocked for a charge of £15.
pity ur not on contract as they do it straight away for free

Thanks for your replys. I thought it would be just a case of using a workround to install a generic rom and in turn this would take the sim lock off! I may jusy return the phone and buy a sim free version for a bit more. Cheers peeps.

[Q] Will this phone work on 3g in Europe & UK ?

I bought my SII a few days ago and am wondering if it will work in Europe.
Also, will t-mobile give me an unlock code? I've been with them for over a year.

I got an unlock code for mine and i have only been back with tmobile for 60 days. Just ask them in chat. It will work in Europe but I don't think it will be on hi speed network.
Sent from my HTC Flyer P512 using xda premium

How quick did you get the code? I just called in and made the request. She said up to 14 days.
I think Europe 3g band is 2100 which the t-mobs SII supports. But I don't know if that means it will work.

Yes it will work on 3G in Europe... I've taken TMO phones to Spain several times and was rocking 3G on Vodafone the entire time.

if it has the frequency it will work

Awesome, thanks guys.
Tmobile just sent me the unlock code. Is there any way to enter it without another sim card?

Could 1 of you guys request the Unlock code for my Galaxy S II? I don't have t-mobile, I brought the phone from a 3rd party phone shop. I have a receipt from the shop, but I'm assuming t-mobile wants a receipt that it was purchased from them. PM me if someone will help me pls.

It's not possible to do this for you, need TMo SIM, they check it.
You can pay one of those services a small amount of money for a code. It's fast and less hassle than trying to get TMo to give you one.

That's not what I meant. I'm asking how can I enter the unlock code? T-mobile said the only way is to put in a non-tmobile sim card and then it will prompt for it.

There is currently no 'free' way of sim unlocking your device if you hang around long enough someone may write a program to do it but you may be waiting a while. Quite a few members have stated the unlock code can be obtained over ebay within 2 hours for around £9 which is a good price. You could also contact your carrier and tell them you want to take your phone abroad and use a different sim card in it while you are away to save costs. Sometimes they will unlock it for free.

got mine unlocked from o2 for free, filled in a form on their site and they emailed me the unlock code

just bought a SIM unlock code from here for £5
instant delivery, works perfectly. awesome

a warning about sim unlock: I got my nexus today from vodafone spain and as expected it was locked. I got an unlock code from ebay and it worked like a charm.
But, I like to play with new phones first, then restore defaults and set everything up the way I want it. The thing is, the galaxy nexus doesn't remember the network unlock code between factory resets, at least mine doesn't (yakju, came with ITL41F).
The codes work, but you may need yours again, so don't throw the number away

any code for three? im waiting the three to give me the code, about 2 weeks now

Hello Mark, is the Samsung Galaxy Nexus an universal phone? Can I use the unlocked version with LTE carriers in the future? I am in US and Verizon is the only LTE carrier I was wondering about using T-Mobile (HSPS technology) or wait for Sprint (my current carrier). I live in USA but I am thinking about moving to Japan so I wonder if I should just wait and maybe I will need to get one in Japan with one of their carriers... Also I love the forums and it is all great, but is there an IRC room for this questions as well?
Thank you in advance,

The GSM version can be purchased unlocked and used on any GSM carrier with their supplied SIM card. The GSM frequencies are listed for the Galaxy Nexus and they cover the majority of GSM international and US domestic carriers.
The LTE version, as far as we've heard, is only for Verizon in the US. Not sure what LTE technologies other carriers in other countries are using.
If you're interested in having an international capable version of the deivce, the GSM version is currently your best option.
Hope that helps!

Hi,
I would also like to purchase such a code, but how ist it with OTA updates? Still avialable?
How would it be if I later root my phone and put on a custom rom? Will it be still unlocked.
or
cant I just put on a custom rom, to sim-unlock the phone and save those costs?
Sorry for the noob questions.
Thanks

Custom Roms cannot sim unlock your phone as it isnt part of the system.
Flashing an OTA update or a custom rom will not affect your phone if you have sim unlocked it with a code.

Hi,
Thanks for the reply.
I have contacted my carrier (A1 Austria) and complained about the simlock. To make a long story short, they finally gave me the simunlock pin.
But recently I unlocked the bootlader and the unlock was wiped so I needed to reenter the pin. After I reflashed the original rom (back to stock) the sim was locked again.
And the most strange thing happened today. I just restarted the phone today (as every day) and the sim was locked again. So reentered the pin to unlock.
My question now, can it be that the simumlock pin they have provided me is not correctly working or is this a normal behaviour or a bug?

Wrong section. Moved to the TMO GS3 forums

You can call T-Mobile and ask them for the unlock code. They will e-mail you in about 24-48 hours. Once you get the code, you put in the new SIM card, and when the phone asks for your unlock code, enter the code provided by T-Mobile and you'll be good to go.
Had to do the same thing with my phone as I travel to Canada a lot.

They always say that just in case you terminate early. I go through a lot of phones, Tmobile will unlock your phone every 90 days, it just has to be a Tmobile phone. You would also need to use the new phone for a bout a week so it could register under their system.

Lg g2 sprint ls980 no sim card - how to unlock it?

After hours of reading i decide to post im really stresfull with this situation. i bought a phone trough ebay i live in dominican republic but when i insert the SIM CARD say " NO SIM CARD" like if i had not put anything. i saw in the post that sprint has somehting modified to dont let no one activate the phone until we call them. i was trying to call them but there are asking me for a phone number and the phone doesnt have any phone number like the CDMA always do.
PLEASE!! there is any way to remove that security and unlock the phone without call sprint ?
if there is any how can i do that because i dont want to lose the money that i paid and im very needing this phone.
i tried lot of thing like the ##3282 and enable the LTE , BAND 26 AND 41 also i have my msl code but nothings appears to work.
Do i need to sell the phone for parts or i will need to wait till someone resolve this problem bz as i think is a software solution ....
Thanks for all

Bottom line you shouldn't have bought the Sprint model. Sprint sends out the unlock code/unlocks the phone over their network and you being in the D.R, you're out of luck.

It's not as complex as you are making it out to be, don't crush people's hope if you don't have facts behind it. Yes it wasn't a good idea to get the sprint one, but the deed is already done. Both the S4 and the HTC ONE were unlocked without sprint sometime after their release, I believe it will be the same case for the G2.

...and you have the "facts" that the G2 will be unlocked or you just want to "believe"? This belief of yours is based on what facts exactly? The HTC One and S4 are/were much more massively popular devices and attract much more attention. You are chastising me for being a realist yet all you're giving the O.P is your belief, just that.
I'm not crushing anyone's hope (where in blazes did you even get that from ). Why suffer through the wait for an unlock when the choice is there for O.P to get rid of it for as much as he/she can still get for it and get the GSM version.

Hi,
Happy New Year everyone!!
I'm in India and am getting a great deal on a Sprint LG G2. Only thing is that i have yet to find an unlock for it. Do the codes given by the unlock sites work? Or does anyone have any sort of idea/clue?
Please keep this thread alive. The price difference for me is substantial and I have kept my purchase of the LG G2 on hold for the moment.
If anyone can help I would be really grateful.
Regards,
George Mathews

sometimes they can also give you unlock instructions thro email so what I would do is call sprint and ask whats the worse they can say? all they can really say im sorry but we cant help? I would really just call sprint

I just got the tmobile model I paid 100 bucks more than the sprint model on craigslist. I dont have sprint service and they told me that i have to have a 2 year contract with them. That they wont do prepaid plans to this phone.. Ridiculous but that's how they work. As Sprint i dont think they will unlock your phone since you didn't bought it from them.

Sprint's international phones get unlocked OTA (Over The Air) while registered on the network, meaning the unlock codes/mechanism are sent to the phone from Sprint itself. Unlocker websites will not work.
Other alternative is to wait for someone to develop an unlock solution like they did for the Sprint HTC One and Galaxy S4.
...or get a proper GSM LG G2 variant.

Oh, you guys are going to laugh... it's so simple... edit /system/build.prop and change ro.build.target_operator=SPR to ro.build.target_operator=OPEN
THAT'S ALL FOLKS! I see this is from last month, but some may not know that yet, and I came here by Google search, because my stupid phone which is an active Sprint phone started showing no SIM card, and I can't figure out how to make it go away.

Edit prop file in systen folder and remove Spr in: xxx.carrier=SPR
Basically delete SPR at the end of the line. And your sim will work. Verified.
Hope this helps someone. I get so much from this forum and hopefuly I can give back.

Download ROM toolbox which has a built in build.prop editor (You must be rooted to do this). If you're doing this, change the OPEN to spr (lower case) and then reboot, otherwise you will get system UI crashes.
But... there is now a permanent unlock for the ls980. Please check the Sprint section.
