Hi, well after a long time of search i finally found the original firmware of my carrier... that is telcel from mexico, i really needed it for a warranty procedure, so I hope its useful to you at least for the same thing
NOTE: this is for ST27A devices, if you have the ST27i and you flash it, the i will turn in an a (meaning it will stop being the international version but the american version of the xperia go)
please hit thanks if it was useful
FTF file is HERE (depositfiles)
and HERE (Mediafire)
I bought an international version tho i need an american one, do you think maybe i can get 3g to work if i flash this ftf??
Edit: Sadly no, 3g won't work i guess it's about hardware.. i didn't really knew. too bad, all i will get with this phone is edge

Hey guys some of you requested a media fire mirror, so i just uploaded it and updated the OP :highfive:
I have the ST27A, but the US version. Are there any important difference between the US and Mexican firmware?
I'm trying to sell my phone used to get something else, and I've been looking for st27a firmware, haha.

well the main issue about this firmware is that it has all the stock useless things that telcel (the carrier) puts on it, so its a very shi** FW, what i could recommend you to do is to put the CE firmware and then with root explorer modify the build.prop to change the version to a st27a, but this FW is only for warranty purposes or things that are needed for telcel issues... hope at least that helps

Thanks! Now i can flash jelly bean and dont worry about warranty!

Has anyone tried the "ATT Developer Device" Portico Rom? Does/would it have 3g enabled? I have the Build edition Lumia 920, but it bricked during a reset. Not sure if this would be a good rom to use or not. Thanks!
Did you ever try this ROM? I'm curious to see if it allows for tethering.

HI,
Yes, I have AT&T branded 920 and I flash it to dev rom due missing features as sms delivery receipt, 2g/3g/4g switch.
If anyone in US can confirm I'm all over this

Could you please provide where you got the dev rom from and can you enlighten us in regards to whether your device is in fact a developer edition or a plain jane AT&T branded device; thank you!
I downloaded the dev rom through NCS a couple days ago along with a backup of my stock firmware.

HI,
Mine is black AT&T lumia (059L848) and I downloaded via NCS.
I got the product code of dev edition (059R2L5) from this link http://forum.gsmhosting.com/vbb/f60...ting-care-suite-download-1660094/#post9434277
So I just tried flashing that version to my black AT&T 920 and it gave me the error Platform ID check fails. Says the FFU file is not meant for this product. Platform ID of image does not match with the platform ID of the device.
Did you flash to any other version prior to going to the dev rom or straight from stock ATT to ATT dev? Perhaps I have to be on an earlier version of the stock ATT rom to do the flash to the current dev rom?

You have to flash to non-portico Rogers rom like RM820_1232.2109.1242.1002 in order to flash your AT&T nokia.

But that will prevent me from going back to the att stock ROM correct. At least it looks that way from the other posts I have read. Wish I could find someone on att that is on the dev ROM and confirm that tethering works coming from a stock branded ROM.

A forum member manage to flash back the AT&T stock rom, but I can find the thread / msg with his steps...there is a app in the store for tethering. It was released last week i think. Did you try installing extra keyboard layout - someone mentioned that this can allows tethering
im flashing to this ROM right now... i was originally in AT&T stock but moved to Rogers pre-portico then jumped to european trying to get to Stock ROM unsuccessfully i ended up with the Mexico ROM and now im Trying this one...
edit - using Developers ROM
- this ROM work perfect to me now... i have all the languages that i wanted to change my phone with, I get LTE as well as before was only 4G
thank you
So for those using the developer ROM, is it worth doing? What's different about it? What's the branding on it?

Also, is anyone going to try and flash this to C6802 to see if it is going to activate LTE?

I think it is UK, Europe for sure. Unbranded, too.
I actually flashed a C6802 Firmware on my C6833 which took away LTE, but left everything else in tact.
Unfortunately from what I have read the C6802 simply lacks the LTE chip on the SOC so actually there is no way to get LTE.
But feel free to try. If all fails you can still always flash back.

I am battling a different problem at the moment, so cannot try today.
I hope someone has the time to try it out, since from what I understand, C6802 does indeed have same SoC as C6833, which is SD800 MSM8974
There were discussions that 'maybe' the antenna could be different, but my gut feeling says it is the same.
Lets see..

Unbranded does not mean no bloatware. It just means, that it is not a carrier branded version like vodafone or t-mobile, o2 or whatever with their special software installed.
What you want is a vanilla android version for the Xperia Z ultra.
Look in the development forums. Maybe someone is working on this.
With root access you can also delete unwanted apps, though in the newer android versions, you can also disable unwanted apps what essentially freezes them.
lol i don't mean bloatware in that way i am fine with sonys UI its just o2 version has o2 bootup and loadsa of o2 software pre installed and i would like to flash it to the international unbranded carrier free
if this what i am looking for?

Do you have Att though? I think he's referring to using the att model on another network like I am doing as well. I'm using on tmobile and some users report, after having to edit system configs to be able to even turn on hotspot without an error, that they don't have any data once connected.

Hello Guys,

Normally, Bootloader checks if region code matches before flash.

In simple words yes It should work with no problems. However It depends on band widths your carrier supports.

The option you're referring to is now housed in Preconfig.

Enable it....to prevent your CSC from changing over when you put in any sim card. Disable it and it will always change.
