Hi everyone,
I'm in canada and own an x10 with rogers.
Last week, I loaded the global fw on it and rooted it. So far everything works great.
Reading up on other posts, it seems like some ppl who updated prematurely regardless of their regions are planning and coming up with ways to update according to their regions once the official updates roll out.
The question I have is, why? My x10 works fine although it's not x10a anymore. So is it necessary to switch?
Hi man, I just finished to re-flash my X10a with the new Brazilian FW (X10a 2.1) i choose to match Phone Version(X10a) with FW Version(X10a)....reflash is so easy why not?
Btw with GlobalFW my bluetooth dosent work with the laptop (1.6 do) but now with the correct FW works great again (placebo effect? idont kown)
maybe beacuse people want to keep their warranty...

Hi can you post your build.prop? I'm trying to put my 2.1 back to Brazil but I must have missed something, cos PC Companion can't download the file. I might have made a mistake with the version numbers...
Rogers will release 2.1 tomorrow.
Or at least this is the rumor.

It's very unlikely, but, some users also like/want their carrier/region specific bundled applications.
And, like, yeah, warranty.

Hi everyone. For those of you who have an X10a, who's planning on flashing to 2.1 X10i software as soon as it's available?
Bin4ry and MarylandCookie have recommended against it, in favour of waiting for an X10a specific 2.1 here: http://forum.xda-developers.com/showthread.php?t=823115. However, I know we're all impatient and want to get new FW ASAP. We also know that in 1.6 ROMs it was not an issue to have an X10a flashed with X10i FW, and in the end, it didn't seem to affect anything, despite the different basebands.
I thought it would be a good idea to have a thread open for anyone to warn others if it brought disastrous results.
So, let's have it: anyone planning on flashing immediately with 2.1 Nordic?
Just want to add my stuff here
You MAY get Baseband issues. So the firmware and everything else should run well, but depends on the carrier you have you can get problems with 3G.
But i personally think that you will be able to flash back to 1.6 everytime using flashtool again, but that is not 100%. Maybe you have to wait for original X10A 2.1 to correct baseband.
Regards
Bin4ry
No point screwing up your phone not having SEUS support. Just debrand using the latest LAM firmware and wait till the official 2.1 is out.
SE LAM stated last week that they were still on target for a late Oct launch so it wouldn't surprise me if it gets released on Monday.
I am waiting....what is an extra day or two anyways...
Well you should be able to extract the baseband from the LAM f/w and then use the Generic Global
Or just wait for Rogers lol and have a seperate thread for the wait on that!!
No point in taking the risk, chances are that someone will try it right away and post the results within 10 minutes of the update anyways, so I'm going to just sit back and let someone elses phone be the lab rat haha.

The potential problems are with X10a phones running an X10i rom but you already know that since the title of the thread is phrased correctly. Just want to avoid further confusion there...

He meant x10a users waiting for x10a firmware. Seems to have been a misunderstanding here. This point was referring to x10a users flashing their handsets with the Nordic x10i release of 2.1 but were advised to wait for the LAM release or their Rogers.
Hi guys can please someone let me know whats going on? My question is why u dont advise flashing an x10a with x10i? My phone was originaly the stock rogers one and was x10a but to debrand it i used 026 x10i rom a few months ago and now its 026 x10i global generic. So can i flash this 2.1 rom?
Sent from my X10i using XDA App
In a nutshell we had x10a baseband for 1.6 but for 2.1 we dont.
You could try flashing it without the x10i 2.1 baseband but we dont know how that will go down and how that will affect functionality of 3g, radios, mediascape etc so we advised against it. At your own peril .... lol

There are files on those guides to change back to X10a, and it's my understanding that if you've flashed a to i or vice versa you can't use SEUS to update.

My bad. The first X10i should be an X10a. Edited.
As for assurances that it can be reversed... I'm confident that even if it doesn't work, someone here with figure out a way to reflash X10a firmware... but the bottom line is that it is unlikely that it will be irreversible, but we cannot know until someone tries.

man ive been reading this for days on end, and im confused as hell.
i have a X10a, i flashed generic global, now it shows up as X10i, does that mean its stuffed?

Anyway, I think you're fine mate, as long as you flash back an X10a firmware. People say that SEUS doesn't work if you 'cross-flash' but maybe you can just wait till Sunday evening and see if u don't get any update, and then flash back

IMO, I think we are perfectly fine with the x10i 2.1 version coming out (if we can flash it)
There is a possibility for it to go screwy but I think we proved it won't by using previous x10i roms on x10a. I honestly doubt that they would have changed this, if they were this concerned about it then 2.2 would be out.
I hope my intuitions are correct I'll probably try it first day (just not the first person )
Hey everyone,
Was just wondering if Australia has got this update yet?
Today I thought I might check if it has came yet so I opened up SEUS and checked for updates...
I box did come up and said 2.1 update is here blah blah blah, do you want to install it?
I thought it might brick my phone if I try update it on top of my Rooted x10 so I did i clean factory reset and tried updating it through SEUS again but it doesnt come up anymore?
My phone keeps saying my software is up to date and so does PC Companion and SEUS. ( Phone firmware is still on 1.6 on phone)
I uninstalled SEUS and tried again but same outcome...
Does anyone know why it wont show up when my phone isnt rooted and does when rooted?
Is it even out in Australia yet?
Answers would be very appreciated,
Thank you, Chad.
It shouldnt brick, you need to have your phone rooted, and then to change your region code, Global Generic code works fine.
It shows up with an update for me, but it doesnt actually start downloading :/
How do you change your Region code?
Is there a link you can give me mate, or some information?
yea mate, just look at the first post of this thread
http://forum.xda-developers.com/showthread.php?t=824711
you could also use as an alternative the global generic code instead of the norwegian code thats put in that thread which is 1232-9897
It appears someone here in Aus has already received the update.
Either that or they aren't the brightest and flashed their X10 and still believe their device is somehow evident of an Optus release...

I just checked through PC Companion and it's still telling me that my phone has the latest software. I checked OTA as well with the same result. I'm going to check using SEUS and see if what that tells me.
Where in Canada are you? I'm in Edmonton and nothing yet for me.
Ya same here nothing im in ottawa
Just checked using SEUS and still nothing.
I saw on the Android forum that a couple people in Ottawa got the notification but it doesn't seem to be consistent as other people in the thread said that they weren't getting despite them being from Ottawa as well.
I'm curious if anyone has found a way for those of us with an x10a running x10i firmware to easily trick SEUS into updating for the x10a. I'm currently running the Nordic 2.1 and would love witch to Rogers 2.1 once it's released....anyone have any ideas?
I do recall something about the updates being "staggered" to minimize the load on the servers.

there are several posts on how to " trick " it into taking the update so just wait a bit, someone will post the firmware with the flash tool, same one you used for nordic and you will be all set.
All of the posts I've read indicate we shouldn't mix x10i and x10a codes as SEUS would either not work or ignore the phone. Unless I missed something?

If I understand the posts correctly they are much like the Nokia product or region codes.. with said codes it will tell the server where you are located. So its like a address of sorts.. the server checks the phones and says Oh Hello! You are in Canada here ya go.. or Hallo! Sie sind in Deutschland .. as I said someone will surely post a how to guide. if you mix the codes you will have a phone with firmware from another country well that is my take on it.

Then do us a favor and update the FW from your PC companion/SEUS folder.
somebody will decrypt it.
I just talked to a Rogers technical support representative and was told that the update has been released, but Sony, as usual, did not prepare for the immense traffic and the link to the download is up and down. I was told that we should be able to update later today, but that the only way to check for the update is through PC Companion - it will NOT appear as an OTA notification on the phone.
Hope this helps!

I'm with Tux. I'll wait for some other helpful Rogers user to post the firmware, and then I'll look into flashing to that.
Haven't had any problems with my X10a running Nordic firmware (other than taking longer to get started with market downloads), so I'm not in a huge rush. It would be nice to have proper X10a firmware though.

Well one of us is misunderstanding at this point. I'm not home at the moment and don't have time to link, but the thread in here somewhere states very clearly not to use an x10a CDA if you have an x10i phone as SEUS will not detect the phone. I guess I'll just wait I guess.

That was for 1.6 fw
For 2.1fw Binary (or was Jerpelea) wrote that is ok to use it as SE probably unified the basebands.
Problem is, my 2.1 is crashing about 5 times (or more) daily.

Using the CDA trick works. I have the global X10i firmware on my X10a and changed it's CDA to the generic Brazil one and it gave me the option to repair to the X10a 2.1 generic brazil firmware. I am assuming that the same can be done with the Rogers CDA once it fully goes live.
I didn't do it as I am happy with the global one....no issues.
Just to clarify, I actually work for a particular company that is involved in this, and we were notified that the update was to begin rolling out today.

Hi All,
I've recently purchased an X10 and while its quite a nice phone, I'm sure it would be a hell of a lot nicer if it was running 2.1 - some things which are "missing" in 1.6 have started to annoy me haha.
To this end, it would appear Telstra are about the slowest telco on the planet to release an update. My current firmware is as follows:
X10a
Country: Australia, Brand: Telstra
Phone Software Version: 1227-4612_R2BA023 GENERIC
I understand that if I follow a tutorial such as the "Debrand your Xperia X10 [Tutorial]" on xperiax10.net (google finds it, I'm not allowed to link yet sorry!) and debrand it, SEUS will then automatically update my phone to 2.1 next time I try to update.
Can anyone tell me what is a good X10a firmware for use in Australia? Note that it needs to be X10a since I use an 850MHz "nextg" network. The list on the link above appears to give me a rather limited set of choices, none of which sound generic or australian (what makes latin america latin america??).
If anyone could give me some hints that would be most apprecitated!
Thanks,
Tom

Which no doubt stems from xda, so you might as well use the original guides from here.

And give this a read too - Step By Step Flashing 1.6 - 2.1

Hi,
Thanks for the advice! I followed the tutorial and updated to 504, then flashed again to .24, however on both of these my bluetooth does not work :-/ Windows 7 shows nothing in the services menu and the phone seems to pair with devices but never connect. Also the .24 ROM available appears to have been a X10i ROM, this doesn't seem to have mattered though as 850MHz HSDPA still seems to work.
Any thoughts on fixing bluetooth?
I haven't installed the rooted version btw and I'm not quite sure what xrecovery does? Thanks!!
Fixed BT - turns out it didn't like to talk to my MacBookPro on Windows - updating Boot Camp drivers to 3.2 fixed that.
As for xrecovery, what does it do? And how does one root 0.24?
Thanks for the help!

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??

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
