Kippu, the software will work 100% you need to make sure

1. Your software version is 2.1
2. There is no simcard in the phone when running the unlock
3. The phone model you are trying to unlock it supported.
4. Firewalls are turned off (it can interfere with the unlocking process)

*If you have any problems just call us at 1-800-507-9077 or you email us at [email protected] and we will gladly assist you

We apologize about the late response here, we did not know it existed. Most people have been refunded already for the software with issues. However, if you are still receiving an error follow these instructions:

Make sure there is no simcard in the phone,

Uninstall drivers and program > turn off firewall > reinstall > run unlock again

Even though is states you have no credits, as long as you are using the computer and phone you will be able to run the program again as many times as you like.

*You can test this by inputting a non accepted simcard to see if the phone still asks you to enter a code. This should not appear anymore after your phone is unlocked.

*Firmware must be 2.1, if you don't have it you can download Sony Ericsson PC companion HERE. You will use this to install the firmware 2.1 for your Xperia device

Hi, when I use the original SIM it says. "your sim does not allow a connection to this network" same message when I use the new sim so I don't think the phone is unlocked.

roman02 thats the exact error I got.

When the phone boots it says "please insert sim card and restart your phone" even though it has the sim in it.

Now cellunlocker wont even return my emails and can't get a refund from paypal either.

Any help please.

hi,
I have this same problem, I used cellunlocker.net too. When I contact suppot they tell me my phone is unlocked. Now I can't use any SIM card. Somebody can help us ?



@Xperia_X10
If you solve this problem, please write in this topic.

moved this to the correct forum

Do you get any different errors when you use the original vs new sim card?

Can anyone help me please, I used the unlocking software from Cellunloacker.net to unlock my company issued Xperia X10. The software error of and gave the error:

Performing last tasks..
Step 3 takes about 20 sec
If the process halted reboot the phone, soft and try again
There was an error while validating EPROM! Please try again or contact support.
Done

Now my phone wont even accept my original SIM card and cellunlocker.net wont offer a fix and keep telling me my phone is unlocked.

Any help to fix the phone would be appreciated, I already had to spend £300 replacing phone.

Thanks in advance
