[Q] Change U20i to U20a - Sony Ericsson XPERIA X10 Mini

I live in New Zealand and have 2 Mini Pros. Both phones are Firmware U20i phones which work on Vodaphone no problem but only partially on Telecom Xt. Telecom XT phones use firmware U20a. Love the phone but I need the rural coverage Telecom XT provides.
I want to convert both phones from U20i to U20a. Phone 1 is from Singapore now updated to Android 2.1. Phone 2 is from Vodaphone N.Z. and has had no updates, its stock Android 1.6
I know there is some doubt as to whether it can be done as it could be a hardware limited also. When phone 1 was inially updated it had full access to the Telecom XT network. After a day or 2 the software seemed to lock it down to inner city use only. I think this is the 21ghz band Telecom use for inner city fill in. So phone 1 is worth a try.
I intend backing up phone 2 useing xrecovery so I can restore should any thing go wrong. It also gives me a simple method to put phone 1 back to 1.6 if needed.
1st question.
Does xrecovery, backup user data includeing apps, android whatever version installed and the phone firmware in this case U20i?
From here on I must admit Im unsure where Im going but Im confident I can get back to where I started should it all turn to custard lol. I seem to have 2 options to rebrand or is that debrand.
This method
http://forum.xda-developers.com/showthread.php?t=777660.
2nd Question.
It seems almost daily, new tools and methods are created and this method is 3 months old. Is it still the best method to use?
The second option is to use xrecovery and load a Rom from a U20a phone.
3rd question.
Where do I get a Telecom XT Rom file from? Or for that matter any other U20a ROM. So far I have only seen U20i modified Roms available.
Im not sure yet about flashtool but its possibly used in congunction with xrecovery
I guess what Im asking is for some reassurance and advice
There seems to be alot of collective knowledge and experience on this forum I cant hope to emulate. Their also seems to be alot of goodwill to helping newbies which Im trying to tap into.
Any advice you can give me before I start I would be gratefull for.

Its hardware limited, sorry. If it wasn't then I wouldn't be using 2degrees on my U20i right now
The only reason why the U20i was working on XT is 'cause you were on the infill 2100mhz fill in....

ive gained quite a bit of experience in the last few days using a number of tools but still no sucess getting service on Telecom XT.
The phone I have is from Singapore. When i initially updated it I had good signal from Telecom XT. i live 50km from the city and it was impossible to have been the infill 21 gig band.
I have tried numerous edits of build.prop again with no success.
Tried aPaullyG's f/w thread http://forum.xda-developers.com/showthread.php?t=777660 who posted a binary from a brazil source but Flash couldnt use it.
What i would like to do for my own peace of mind is to flash a copy of 2.1 f/w from a U20a phone. Any country, doesnt mater.
havent tried xrestore yet but will later in the day but still need a file of genuine 2.1 to exhaust all possibilities.

I have just been given a Telecom work phone, but I am addicted to the Andriod on my X10, which is my personal vodafone mobile. I would love to use my X10 for work but I also have a U20i so it only works in the City with the Telecom sim. If you manage to get your phone converted to a U20a please post some instructions as I would love to do the same.

Hi Purplerust, I have an Xrecovery backup for my Australian X10 mini pro u20a running 2.1 if this is useful to you. Zipped it's 210Mb. Have not installed a cutom rom yet, just figuring everything out, backing up etc etc... Looking forward to getting Cyanogen on there, but am not yet sure what I need to do to get it working at 850MHz for the Telstra NextG network I'm on.
PM me if you want the image -
cheers,
Richard

The problem is hardware based, if you flash a u20i firmware to a u20a your left without 3g you're stuck on edge and the same goes the other way around.
May I ask why couldn't you use apaullyg's file?
As far as installing a custom ROM on top of it you can always flash to the latest version and root/xrec and install owain94's either floyo (currently using) or gigglebread which both work pretty darn good.

How do i upgrade to 2.1???

Sorry the nobbness of my question, but i really cant get it...
I have the x10 mini phone, i have rooted it with Exploid method (by the way, i still can get the list command to work, and neither uninstall aplication, if you want to help me with that too), im from Chile, and have an Entel pcs "account".
When i conect the phone to pc companion, it says that my phone is allredy upgraded, but it is still version 1.6..
Does it has something to do with me, being in another country, with another mobile company? Or is there a method to upgrade the phone that isnt pc companions one?
Anyway, ill apriciate a lot if yuo guys can help me...
...so thanks!
You need to debrand to a generic rom (Generic UK works for the X10mini) - if you bought your phone from an operator then it'll have a customised version of the rom - Operators will take a while (or never!) to update and release their customised versions of an update. Using the generic rom bypasses this, and you get the software directly from SE without any of the additional operator bloat

The "H" your seeing stands for HSDPA...which is actually better than 3G. As for the browsing problems, after you flashed the 2.1 generic and started your phone up for the first time did you properly add the rogers APN settings or did you choose automatic internet settings?
I flash my X10a with the nordic 2.1 firmare and I also get the "H" and I added my rogers apn settings manually and my phone is absolutly perfect. No problems at all.
If you need the proper rogers apn settings to use you can pm me.
I upgraded to 1.6 Generic UK to then get the 2.1 upgrade last week as could not wait for Orange...
Yesterday, Orange came out with 2.1 and so wanted to get the new Orange update that just came out, so I followed the debranding method from xperia.net but instead of using generic UK db files, I used my old ones I did a back up of! Took me about 6 attempts but finally got the timing right and hey presto, old 1.6 Orange was back.. and then it told me I had a new update waiting..

H = 3.5G = faster than 3G. In 1.6, there was H, but no icon to differentiate.
Video:
Same question, very important for me! X10a, Rogers, branded, locked, un-rooted (yes, I'm just a simple user, not a crime a believe ) -- upgraded via seus to 2.1 rogers. Too many bugs for me to keep it, so jsut wanna go back to 1.6 rogers if possible! Is there a step by step instruction to use in this particular case? Thanks!

Flashed U20A to 2.1 and now it says it is a U20i

Hello,
I have just flashed my U20A in Australia to 2.1 and now I cannot access Three's 3G network as the phone is being detected as a U20i, is there any fix?
Also, is there any chance I will be able to recover the Planet 3 application from somewhere?
EDIT: I fixed the 3G by editing build.prop, I was wondering if there is a way to make it so that a specific website goes through an APN even if you are connected to WiFi.
Thanks,
Tanis
Flashed U20i
Hi Tanis,
Im pleased you seem to have overcome your problem. Im hoping to use a bit of the knowledge you have gained to get me thru a change I want to make to my Mini Pro.
I want to change from U20i to U20a.
Im presumeing you flashed to a 2.1 Rom you downloaded from some where. And that it was obviously a U20i build.
What steps did you use and what Apps did you use.Iim probably more interesested in the edit you did to build.prop. Did this requre rooting or did you edit the file before reflashing to the phone.
You seem to be on network carrier 3 which I believele has all bands on their mini Pros made available. Is that correct? If so what is the CDF number you used please

[Q] AT&T Xperia X10 Gingerbread Update for a X10 Unlocked By AT&T

My friend had the an unfortunate but common experience with his X10.
Its an at&r version, and he finally got the 2.1 update only to see "X10 gets gingerbread" plastered all over every android news site. After calling at&t and Sony Ericson, and after being transferred to manager and manager, they emailed him instructions on how to "unlock" his phone to get the gingerbread update.
In the instructions, it tells him that he needs a sim from another carrier. The problem is, in our area, only at&t and Verizon are prevalent. From my old Nokia days, I thought an unlock code was an unlock code. You unlocked the code and then were free to use it on any sim supported carrier with a device with compatible frequencies. I've never actually heard of an unlock that required an alternative sim to complete the unlock process. Nor have I heard of a phone that after it was unlocked, would receive an update.
Is this true? If it is, we have no chance at doing this the legit way. Which method of root, and which ROM would give us the easiest time, and the closest to stock experience. He isn't necessarily the techiest, but loves Sony. Were not necessarily looking for the most features, but would greatly appreciate if he could upgrade to gingerbread.
I'm not an expert by any means, but I have rooted, flashed, and installed ICS and customs rooms on my Transformer mainly using Clockwork Recovery. I've also rooted, flashed a custom over clock kernel, and pushed modified files over ADB on my AT&T Galaxy Note, released a mere fees days ago. This should give you an idea of our experience level.
There are dozens of Roms and sites with tutorials, but they're all convoluted and don't take into account the presence of other methods and rom to explain why their's is better. They also don't tell us when they're outdated.
So, to the point, and to sum it all up: does this sum unlock allow for a blessed OTA update? If we actually need another carriers sim, were out of luck. In that case, which method and rom would be easiest to root, and then flash. Is a from like cyanogenmod (seemingly the go to for handsets) available? I don't have a Rosetta stone for X10 roms , recoveries, and root methods.
Thanks very much.
At&t has no plans on releasing 2.3 I have no idea what an unlock code has to do with an update.
I upgraded my att stock x10 2.1 to 2.3 without a problem. I flashed using the North American 2.3 found here http://forum.xda-developers.com/showthread.php?t=936733 You'll have to look at all the pages to find a working download.
I also got the flash tool from this thread http://forum.xda-developers.com/showthread.php?t=920746

Is it possible to get a virgin ICS ?

Hello,
I've been a couple of weeks trying to understand how this all works. I have an Xperia S from Movistar (Spain) unlocked by imei. It is a LT26i serie 1257-5612.
I tryed to update it through SonyMobile, but it just updates de firmware. What about the OS?? I just want to kick out of my device all staff from Movitar and get the virgin ICS ROM running, so what can I do??
Please, I'm just tired of reading and readin thousands of posts with different ways, steps variants and so on. Is there anyone that can tell me what are my choices and exactly what to do?
THANKS!
If your current system does not include anything you need and can't get otherwise, f.e. APN data or something like that, just grab a generic ICS image and flash it with flashtool. For what it's worth, I had the same problem with my german provider and it worked for me.
Sorry, can't link you, am still under 10 posts
