[Q] Downgrade from 2.1 to 1.6 - Sony Ericsson XPERIA X10 Mini

So, as most of us went to Nordic 2.1 x10 mini pro update I would like to get back to 1.6 (preferably to original O2 Germany version but any version will do).
I have tried editing build.prop in 2.1 to values 1239-2971 (these values were from my original build.prop in 1.6) but SE Update Service says that there is no new updates. I guess that this doesn't work anymore
So, is there any old software backup of 1.6 available for downgrade?

Try deleting the db folder in /Update Service inside your program files

That doesn't work.
I could try putting 1.6 build.prop (original one that I had before editing and updating) but I am afraid not to brick my phone.
Is this safe to do?

Don´t do this. I tried it already. Doesn´t work, and will put your phone in a boot loop.

May I ask why you want to go back to 1.6? Is there something not right with the 2.1 upgrade?
I don't have it yet and am not sure if I want to upgrade if it is so hard to downgrade.
________________________________
edit: I have found the list of issues with 2.1. I will follow this thread to find out how to downgrade if I'm not satisfied with 2.1.

I´ve paid to Davinci to downgrade to 1.6 because of the keyboard issues. I use Palm Graffiti in portrait mode and with my physical keyboard already being german, having Swedish layout on top of it was too much. Will wait for German update to be available. Otherwise no problems at all, only benefits - better battery handling in 2.1 etc.

Ok, thanks for letting me know.

It doesn't have any big problems, but as vlissine said there is this annoying thing with the keyboard. And as german update to 2.1 is coming out soon I would like to get back to original 1.6 version.
Also, I don't know is there any difference in Marketplace between countries. For example one application could be present on german version, but not on nordic.
At first glance there is not that much big of a difference so that you MUST switch to 2.1 immediately, except if the nordic version is suitable for your use.

Hm, no, I'm not planning to go nordic, I will wait for the update to come to Belgium.

u should try omnius instead of davinci. they charge per day of use rather than per flash and its cheaper

I did omnius when I unbranded my phone. This time I used Davinci just to compare. Omnius has one disadvantage - you have to chase their dealers to get credits credited onto your account while at Davinci it is straightforward and immediate.
Also charge per day might be interesting for those who want to flas a bunch of phones, not just one. But I agree omnius is cheaper and is as good as.

When Locale updates arrive, changing your build.prop to your generic one, and then using SEUS to repair your phone would do the trick. You will be changed to your local 2.1

I tried just to test to change Nordic into Russian by using this technique. Didn´t work.

I manage to downgrade to 1.6 for FREE. lol
Just download the FW for u20i NL 1.6 here > http://forum.xda-developers.com/showthread.php?t=827273 and use the Flashtool from Binary's post.

Thanks zanndoth, this worked for me very well.

Unfortunally it doesn't works for me. Did al the steps (downloading flashtool etc.) but when I startup my phone I get the animating splash screen en after that a 'frozen' SE logo.... Still there after 15 minutes... Can someone help?
Ok, finally, after waiting longer, it finally works.
Thanks to you all!

[Q] Can I switch from Nordic 2.1 to UK Generic 2.1 when it comes out?

As the title says...
I've tricked my Generic UK phone into thinking it was nordic and got SEUS to upgrade me to Nordic Combined 2.1... I've rooted it using Superoneclick..
I've had a look around the forum, but to be honest there's so much out there it's like searching for a needle in a haystack.. I've tried various search strings but to no avail...
So.. has anyone sussed out how to switch from one 2.1 ROM to another yet, cos as soon as the UK Generic comes out i'd like to switch back to it to get my warranty back in place!!!....
Thanks.

Yes you can. I'll update my guide on how-to do so very soon.
Wow... That's the quickest response I've ever had to any question, anywhere.. including when I asked my wife if she wanted me to buy her a new handbag she'd been drooling over!!
Thanks!
Will I be able to install brazillian 2.1 Generic version too when it comes out?

You should, hopefully the method to debrand/rebrand by switching the version's code will work with 2.1 and it will be really easy. Just wait a couple of days after it has been made available in Brazil and I'm sure someone will post a tutorial here.
I'm interested as well. I'd like to switch back to UK generic unbranded. Keep us posted please!

i think it would be best to grab the X10 flasher from these forums, and then wait until the firmware is released. give it hours/days, and the firmware will probs be available somewhere, and you can then place the firmware in the firmware folder of the X10 flasher.
Alternatively you can change your default.props, but I haven't properly looked into this method as I used the flasher to go global generic, and to be fair, don't really care much for flashing across to UK generic, I dont see the point.

[Requested]X10 Mini Pro Biuld.prop 1.6 SG

Custom SG X10 Mini Pro build.prop for 1.6 as requested by porcupineadvocate.
This is the build.prop i used to update my 1.6 to 2.1 -update1 2.0.A.0.504 5 (u201_1238-7173)
Have fun!
Great, thanks
Aw, replacing my build.prop with this build.prop had no effect
Could you upload your post-upgrade 2.1 build prop? I'm trying to see whether it's possible to duplicate this method, for the pro instead of the normal mini. Which entails swapping the 2.1 build.prop in instead.
i upload 2 build.prop in this file. try the 2nd one if the 1st one doesn't work. sry about that.
Btw, this is for 1.6. If u're already on nordic 2.1, flash to 1.6 and use this file to update via SEUS.
Ahhh... but do you have the build.prop after upgrading to 2.1? Because that's what the other method calls for
(yeah, I'm on 1.6. But it's currently UK/generic)
I can extract that from my phone. However, by changing the build.prop on 2.1, i wasn't able to get any update for SG. Other users have reported that they're able to change and update successfully though. I'm trying to get more info from them and try out the next few days to see if it can be done on 2.1. Will keep the community updated if its successful.
You're great, thanks.
Okay, never mind. Changing the code in my (generic-UK) build.prop to 1238-7173 (the code for generic-SG?) and then restarting managed to get it to update.
that's good news. which means it didn't work last time cuz the updates for sg weren't out yet.
sg as in singapore phones?
my phone was branded by singtel singapore
yes evo, as in singapore. u can see the flag on the left side ya?
the unbranded 2.1 f/w for sg is available, not sure about branded ones (m1,singtel,starhub)/ will check later today since i don't have to work.
mine is singtel branded..
is the official update out yet?

Worked for my U20i, too.
Greetings (and many thanks) from Chile.
can you help me??? i need build.prop code for region indonesia.....please help me
No idea man. try going to a phone shop and take a look at phones. U should be able to see it inside the battery compartment for x10, x8 and mini x10 series.

Why am I World Generic?

I have a UK supplied and UK used phone, updated normally through all progressions as a regular user (as opposed to someone who knows what they are doing) in the UK using SEUS.
My phone now shows as World Generic. it was UK Generic before THE 2.1 update. It also tells me that the software is up to date despite this new little update that has been around (in UK apparently) since before Christmas.
Help. I'm confused.
It does not take a lot.
I want this latest upgrade to see if the incall volume can be increased as it is currently pants.
PS. Aviation medicals over many years suggest I have no hearing impairment, as does the use of SE W980 and SE K800i.
SE themselves seem to suggest there is no problem with the volume of my X10 PDA - can't bring myself to refer to it as a phone...........................

It's normal, it's just the way it is. Go to Settings - About phone and tell us what Build Number you're using?
2.0.A.0.504
Well the latest is 2.0.2.A.0.24, so if you don't want to root just use seus which should update you to it, if you want to root it then you need to install THIS, because the current root methods don't work with the update you'll get using seus.

I need Stock ROM v1.6 Build No:1.2.A.1.174 baseband version:N/A

Please if someone own this version I need it very because my hardware keyboard id dead, and I want to send my X10mini pro back to my dealer, and this version was on phone when I bought it.
Without this version they wont accept my warrnity!
I tried searching for it everywhere but can't found nothing!
HELP!
Flash your phone via sony ericsson update service, your phone updated to android 2.1, baseband ...015.
Only way is with flashtool, but you need the android 1.6 .sin or .ftf files and i don't know where to get those.
I won't believe that they only take it back in version 1.6. version 2.1 is an official release and thus they should take it back for warranty issues.
sent with my x10 mini pro
Lol so not true its unreal who told you that pmsl

Hi..and thx for replay.
The problem is that my phone haven't update from SEUS.
I try more times to flash from v1.6 and SEUS said that I have the last version on my phone (in my country).
I read om few forums that people complain that SE won't make update for our country and they have not courage to flash with other ROM because of warranty..
Because of that I looking for this version of ROM!
I have a backup of this version but no way to install it back because of Xrecovery version. I made it with lower ver than v0.3 and now everytime I restore it back it stayed on Sonyericsson logo.
Its not a update and were not talking about pc companion we are talking about se update centrer ,,,its diferent it works every ware on all sony phones check it out again

I know that we talking about SEUS update center..Who mentioned PC Companion?
Now when I broke up my warranty, a I can to upgrade to 2.1.1.A.06 from any version!
But with version 1.6 (I tried once mounht ago) I can not!
As as mentioned in post above, I found lot of post from serbian forum where people complain the SEUS updater have not newer version for our country!
When you try to update it comes the message from SEUS: You have the latest version!

[Q] How to go back to the Source/Original Android Version? For X10MPro

Hey people.
I wanted to know: is there a way to know what was the firmware/android version that came with the phone when i bought it?
Because i already change from 2.1.1.0.A.6 to 2.1.1.C.0.0 and vice-versa and now my firmware is not the original one anymore :S, I'm from Portugal and i don't know what was the Official Firmware/Android Version that came with the phone when i bought it, i want to installed it back to my phone so i can have my phone Original again without having different firmware. And if that is possible, where can i download it?.
I'll give 'Thanks' to good answers.
Cheers :good:

It came with 1.6 when SonyEricsson brought it out, and they provided updates to 2.1, with 2.1.1.C.0.0 being the last one they provided for the x10mini pro. So if you've got that firmware, your phone is still considered original, if that update was available in your region.
If your phone was locked to a specific provider, with their provider specific software (bloatware) installed, you won't be able to get it back to how it was when you bought it.
If you want to make sure you have the last original firmware for your phone for your region, do a repair with PC-Companion or SEUS. And if you had your bootloader unlocked, use S1Tool's restore function to lock it again afterwards. More original than that is impossible.
Now there's another problem, i don't know where i can download a firmware for the Portugal region, the greek firmware works but it has the keyboard problem 'buttons ç and ," that GB roms also have, so i would need to root the phone to fix that.
So there's no way to get the original firmware back :S.
Yes i can always repair with that but...if the firmware is the wrong one 'brazilian firmware for example' then those programs can't find the firmware for the repair.
I hope i never need to repair my phone and that i can stick with the GB roms, they're so much better than original eclair.
Cheers :good:
