Xperia T unlock problems

jmposvip — Wed, 12 Mar 2014 16:30:13 GMT

Long story short, I have a sim locked xperia T ( LT30p). I went to a service and none of them could unlock it. They dont' know what's wrong with the phone.

In service menu>model info it says LT30p but when they input the imei number in the unlocking software it says Xperia TL LT30at. But it is not a at&t phone, it does not have their branding on the phone.

So what happend to this phone? Can I unlock it? Can I reverse it what ever happend to the phone?

Please help

This phone was flashed with AT&T's firware or if you see the AT&T icon on the front of the phone that could be the cause

I don't my Xperia T next to me but if you open one of the covers you should be able to see a white paper/plastic with info on the device, it will tell you if its a LT30a or LT30p or LT30at

In the service menu it says that it is LT30p.

The problem with your phone is that you don't know if it was locked to a different carrier or not, you will need to get that info to be able to unlock it, either by contacting that carrier or by paying a website such as unlock4cheap

The phone was locked to a german carier and someone did something to it and it has now a difrent firmware and imei(maybe)? number bc it behaves as an at&t phone but it's not and the service guys told me that the phone has a damaged bootloader, other service guy told me that the phone is locked to at&t and they can't unlock a at&t phone.

The phone is LT30p.

in the service menu it says xNetwork0

so it's hard locked to

so....wrong firmware(maybe imei too) and hardlocked

When I check its imei number on the internet it says Xperia TL LT30at

Sony PC Companion sees it as a T LT30 phone but his imei number says it's a TL LT30at phone

Can I change it's imei number?

I think the IMEI can be changed if you root the phone.Take a look on XDA about that.Also,I suggest you contact one of the sony support members from this forum for more help.

Sony please help. I don't know what to do anymore. What did hapen to this phone so that the PC Companion sees it as a TL30p but the imei number is from a TL LT30at. The phone is indeed a TL 30p. At the sony service they could not sim unlock it bc their software showed an error and they told me that they can't unlock it( the service is in a city called Mostar and they don't seem to know much about flashing, rooting...).

I bought this phone from ebay and can't return it. I spend my last money that I saved

Please Sony help

anyone, please??

If you send me a PM with your IMEI i can try to find what operator and country it belongs to.
But from what you're describing i see no other solution then to contact an authorized service location to see if they can customize it back to the correct software and SIM lock and that you then unlock it using an unlock code from the original operator. The current status of the SIM lock is that you have no attempts left at unlocking it.

I'm however not sure if a service location will be able to do that on your phone since from what you're saying, the bootloader and software may have been altered.
