LT30p firmware on LT30at keeping LTE support

Spectre51 · Nov 6, 2012

Okay people now that I have been able to create a stock AT&T LT30at ftf file: https://docs.google.com/open?id=0ByrrmqPijqISREZpSE16bWdKV1E I went ahead with testing if I could flash a generic LT30p firmware on my LT30at EXCLUDING the baseband so I could keep LTE.

I used the LT30p firmware version 7.0.A.3.195 generic and flashed it through flashtools wiping everything but excluding the baseband. By doing this I was able to keep LTE support and have a generic unbranded firmware. I then restored all my apps using the included backup & restore app ( I had manually installed it on the LT30at firmware previously)

Everything went fine but of course I couldn't root using Bin4ry's method with the firmware I used. Also tethering works without issue. I did have to setup the AT&T LTE apn which can be found here: http://xdaforums.com/showpost.php?p=27979729&postcount=4

Is there any way to root then? According to Jozinek's method we have to unlock the bootloader and that's not possible with the TL.

You can root officially via the sony official method. Then you can flash custom kernel.

I have an ATT xperia TL with a locked bootloader, don't think I'll be able to flash custom kernals

Unlock the bootloader to flash custom kernels. Use this method from the official sony website, then flash the advanced stock kernel which has root.

This should work unless AT&T have done somethg nasty, in which case why do you bother with that provider, just change to another company

Ouch, why would you get an AT&T phone then.....with no prospect of community unlock (Test point is not a viable method) then it seems unless you can get a dev to work on root you are stuck. And I think that will be a low priority for devs atm. As far as I know Bin4ryhas not worked on it since it came it...so you may be stuck with it.

Unfortunately AT&T is the only carrier in the US that sells Sony phones. Also Sony hasn't released an unlocked Xperia T for the US and I doubt they will since it's exclusive to AT&T right now.

Sony’s new flagship Android smartphone, the Sony Xperia TL is now available with US mobile carrier AT&T, the handset will set you bakc $99.99 when you sign up to a new two year contract with AT&T, the device is also available unlocked for $449.99.

Doesnt this mean it is available on other carriers? In which case its bootloader should be unloackable.
Forgive me if i am wrong, I am from UK.

That site is wrong. The LTE equipped TL is not available unlocked anywhere "yet". Sony is talking about releasing and unlocked unbranded TL in the US but.its just talk right now.

AT&T sucks in this regard. I have their xperia play phone that came out more the a year ago and still today only way to unlock bootloader is via setool2.

They said the same thing about the ion. 2 months ago I was on sonystyle.com and almost ordered the ion, but called and talked to a rep, and told me "not unlocked yet". He took my particulars so they can call me when the unlocked one became available. Needless to say..........

I say an unlocked TL ain't happening, ever!

They hadn't been talking about unlocked ion at least not the US market. I have a friend at Sony that deals US Xperia sales. TL is being talked about though. But its not his decision that comes from higher ups. Hopefully they do. Of course for the ion you could always buy a lt28i (though no support in the US) for the TL it isn't that simple as the T doesn't have LTE like the TL.

Thanks for all the effort your putting in for the community here. I'd like to get all the AT&T software on the phone and this sounds like they way to do it. How do you exclude the baseband when your flashing?

Thanks

In flashtools just before you start the flash there is a check box on the right that says exclude baseband. Just check that.

MIUI on TL

Hey Spectre51 although the bootloader is locked on the TL do you think it can have MIUI like liuxueyuan1990 has for the ION?

If it doesn't require a custom kernel then sure. If not then no. I don't know anything about MIUI so I can't say for sure.

Is this the one you used to flash your TL?
