O2 Xda ROM Update and SIM Unlock

I see these ?'s have been asked hundreds of times before, however my proble is a little different.
I have an O2 Xda from the UK that was on the O2 network.
I have moved to Australia and wish to use the device on the Telstra network, but the Xda has been network locked. As my device has an old ROM version i think i need to upgrade first, before running xdaunlock.exe.
Can anyone offer advise?
Cheers
:? :?

You have two possibilities to unlock your phone.
If you got an serial cable to attach your XDA you can use the xda manipulator to unlock it.
In the other case i would suggest you go to www.yorch.net, cook your own rom with the 3.17.03 Rom and use the xdaunlock tool....
HTH

just do this simple thing... downlaod xda developers v1.2 and put your xda into the sync cradel with no sim or sd card in then follow it though.......
once done hard reset it....
then it will unlock your device when it starts up
then you can decide to stay on pc2002 or go to pc2003 as your device will not need to be unlocked again

I had a look at the xda-developers v1.2, it would appear my service provider is not on the list (Telstra) will this rom still work or will i have to find a ROM written for the Telstra network?
Cheers :?

the ROM has nothing to do with the operator. It's the RSU version that might not work with your new network. Just get your device unlocked and let's see if it receives the signal or not, then you may have to do RSU upgrade.

Unlock via XDAUnlock?
I have a TMO XDA with ROM4.01.00 and RS6.24.01. I'm selling it and need to unlock it for the buyer.
Is XDAUnlock the path to go?

if i'm not wrong, XDAunlock works only with ROMs with wmodem application and I'm not aware of any wm2003 that has it.
TMO 4.01.00 is available as exe upgrade. just flash your XDA with ROM 3.17 which will unlock your device then reflash back using TMO 4.01.00
good luck

SIM Unlocking
Thanks. Question on the SIM card. All this "unlocking" occurs with the sim card inside? Just to check:
1) With my sim inside, install Yorch's ROM3.17, when asked, unlock phone, finish install.
- Now this means the PDA phone has no phone service, correct? but PDA works?
2) Now install ROM4.01.00, RS6.24.01 with phone unlocked.
3) Remove sim card.
4) Ship to new owner
5) New owner inserts their sim card. Now what? They call their carrier with IMEI #?
Thanks

No, when you put the 3.17 ROM, the phone part should continue working as long as you don't touch the RSU. The SIM has nothing to do with all this stuff. All the locking info is within the GSM firm ware of your device. I would prefer to remove the SIM while flashing the ROM.
If your locked device works now with your SIM, it will definitly work after unlocking BUT it is not a good prove that it's really unlocked. You have to test it with another SIM before shiping to the buyer.
PS: no matter your dial or IMEI is, GSM system deals with a unique identifier for the SIM which called MSISDN. So, don't worry about the buyer

I never realized you could operate the unit without a sim card inside. I guess I'll have to try it and learn along the way. It seems removing the sim card forces a hard reset.
If all the locking info is in the GSM firmware and Yorch 3.17 ROM upgrade doesn't touch the RSU, how does the XDAUnlock operate then?

During the unlock, the 3.17.03 set the phone to a model PW10A. My phone is a PW10B (USA). None of the .exe upgrade software will upgrade unit as they think it's the wrong band. I tried the Bootloader 5.15 - calendar and set the GSM to 900/1800 but model doesn't change in the identify screen. The sim has not been in the phone this whole time.
How do I change the model back to PW10B?

Fixed Wrong Band Problem
I put a ROM 4.0x.xx.nb1 file onto my SD card and using Wallaby Bootloader, flashed the unit's ROM. This appeared to have put the model back to PW10B1. Then I used the ROM4.01.00.exe to finalize the WM2003 upgrade. Phone is sim unlocked. Question:
when does phone become sim unlocked again? i.e. if I was to put my sim back in the phone, and connect to TMO, would that then lock the phone to TMO? Or once it's unlocked, it's unlocked for life? Just curious.

Typo
Should read, "when does phone get sim locked again", not sim unlocked.

The phone will remain unlocked to all networks.

Noob new Blackstone - Unlocking clarification

Guys
I've searched the forums and realise I can buy a SIM unlock code for my Blackstone, however I'm trying to clarify the following.
1. If I install a different ROM do I still need to buy the unlock?
2. If I changed the EMEI (I want the phone to match my in car fixed EMEI - I realise the blackstone has to be switched off when in the car else conflicts) does that mean the phone has to be unlocked again?
3. Once the phone has been unlocked if I change the ROM will it have to be unlocked again?
What prompted the question is reading the Wiki few areas actually simlock the phones....therefore my assumption is a different ROM means it could become unlocked.
Thanks in advance for the help.
Regards

Its an unlocked phone my friend so obviously you pay a higher price for the phone itself able to use with any sim card. Carriers phone that are branded with the carrier logo are usually cheaper with a plan that could cost more then the phone overtime and is locked to the phone carrier which requires a sim unlocking code to use with other sim cards/ other carriers.
The answer to that is you can install any rom on the phone and if it an unlocked htc touch hd which you paid a lot for then it will be unlocked forever
if its locked to a carrier im not sure about that maybe someone can clarify.

any ideas please guys, I get the phone in a couple of hours.

bump
Anyone?

Try to keep this short
1. If I install a different ROM do I still need to buy the unlock?
No Simlock is based on the radio and hardware (short version).
Once unlocked yoiu can up your rom and your radio, it stays unlocked.
2. If I changed the EMEI (I want the phone to match my in car fixed EMEI - I realise the blackstone has to be switched off when in the car else conflicts) does that mean the phone has to be unlocked again?
Got me lost on this one.
Simlock is based on radio and Hardware.
So your IMEI is part of the phone which is either Sim Locked or not.
If you put your sim into what ever is in phone is in your car your number will be the same.
Once you have sim unlocked a device it remains unlocked.
Like I said you lost me.
3. Once the phone has been unlocked if I change the ROM will it have to be unlocked again?
No - Once done it remains unlocked regardless of rom or radio upgrade.
(and if you buy a new Simlocked Blackstrone you cant use your old code as the lock is based on the hardware)
What prompted the question is reading the Wiki few areas actually simlock the phones....therefore my assumption is a different ROM means it could become unlocked.
--->point me to the page that you feel needs updated, i will have a go at it.

code doesn't work

Hi,
I recently purchased a unlock code from unlockadic for my vibrant but when I went to use it it said Network lock request unsuccessful. Does anyone have any ideas?
If this is in the wrong section I apologize
P.S. I did contact unlockadic and said that this has never happened and that he would have to have his guys look at the problem.

bump because i had the same issue.

you need a non-t-mob sim in the phone for the unlock to activate

I have an account with Rogers & that is the SIM l put in the phone-result was unsuccessful. Code is correct unlock code-i got the same code from three different sources but no luck.

hussafilms is correct.
You need to put in a sim from a network that the phone was not designed for. So if you bought the phone from tmobile then put in a att sim or if you bought it from another company put in a sim that is not from that company. So if you have the galaxy s from rogers then put in a tmobile sim or something.

Let me clarify, I bought a Samsung t959 Vibrant from ebay locked to t mobile and I put in my Rogers SIM card, entered the code and it was unsucessful

How many times did you try to enter the unlock code? I beleive if you have three failed attempts, it will be permanatly locked.

Samsung Focus Carrier/Sim Unlock Question

I have an 1.3 rev Samsung Focus. It was an unlocked model I got from outside. I was in the US at the time of Mango update and updated my phone with Mango from AT&T. Now I have moved out of the US and want to unlock it. AT&T doesn't have the unlock code because I didnt purchase it from them. Any Ideas on what I can do? Will a custom ROM help me with Unlock? When I check lock status, it is SIM Lock is Disabled, only Network lock is enabled.

I'm not sure what you meant by "It was an unlocked model" in the context of "out of the US and want to unlock it". Was it unlocked or locked? Anyway:
Read the wiki, (carrier) locks are in NVRAM, no relation to flashing whatsoever, so any custom ROM won't SIM unlock your phone.
Have you tried ebay? Unlock is cheap as $1 and it doesn't hurt to try (unlock via IMEI - I unlocked AT&T and Rogers Focuses). If that fails, I recommend fastgsm, I've unlocked my own AT&T Focus with them, via USB (no affiliation).

It was carrier unlocked, as in I could place any sim in the phone and it would work. After I updated it on my Zune with Mango, it was loaded with AT&T's version and hence locked to AT&T. Now AT&T doesn't have the record of the IMEI in their database and aren't able to provide me with an unlock code. They were able to provide the unlock code for my other windows phone that I purchased from AT&T. Thereby lies my predicament. Let me try the ebay version, if not I hope FastGSM works. Thanks.

I was not able to get the unlock code from ebay. But FastGSM seemed to work wonders. I used their USB unlocking tool and it worked just fine. Thanks for the tip.

Are you sure, Its not the case of Bad ESN? If so there's no way around.
Otherwise you can Order for Unlock code using your IMEI and purchase it through eBay or any other site.
Usually that's how i do. Easiest method to Unlock the device.

what means bad esn ? and how can i verify if it's bad ESN or not ?
i can purshase the code yes but how will i put it ? it don't let me type the code (phone is permanently locked)
thanks

If i describe an easy way about Bad ESN then it would be like, The Phone that you own has been stolen earlier or previous owner has reported it to respective carrier or company itself to Block its IMEI. In such case, Phone will be no longer Phone. Means for calling purpose.
If its a Clean ESN then things are pretty easy as it sounds. At first make sure you're not using the same Carrier SIM as your phone came with. Any other SIM, Insert it. It will basically asks you to enter code. Which will given to you once you purchase through either eBay or any Online site where they Unlocks IMEI for the device specific. Usually its a 7 Digit code, But may vary, enter exactly the same as provided by respected Seller or Anyone whom you've contacted. As you'll have only 10-Attempt to Unlock your device. Once it done, It will show like this: Your Device has been Successfully Unlocked, Now you can insert any SIM-Card, it will work.
To Check whether its been Bad ESN case or not, Just Google it: Bad ESN

thanks for these informations, i don't think the phone is stolen, it works with the owner's sim card, but it seems like the 10 attempts has been tried and can't enter unlock code anymore (hard locked) what to do in this case ?
thank you

I'm not sure, In this case there's any reset counter available or not. But surely if you want play around with your device with Owner's SIM in it. then do few things.
-Factory Reset your device, without inserting any SIM Card.
-Afterwards Purchase Unlock Code either online or contact Carrier company whichever company's SIM Card working in your device and ask them for Unlock Code.
They will basically asks few details and give you Unlock Code for free, Otherwise purchase it through online, but before make sure to insert any non-legit sim in it whether Enter PIN menu POP-Ups or not.
Do these, will possibly reset the counter for you. Or else i'm helpless buddy.:fingers-crossed:

All of this were done and the counter is still not reset, i'm hopeless, thank you anyway
i've heared there may be a solution by uploading a new qcn file with QPS, any idea ?
hard reset is the same thing as Fatory reset ? else ?
thanks
