easy steps to upgrade any (1.6 or 2.1)ROOTED to 2.1 rogers (without flashing) - XPERIA X10 Android Development

it's been mentioned here and there but when I was looking I would have appreciated if someone just put it all in one place. a reminder this is based on the work been done by arkedk in this post http://forum.xda-developers.com/showthread.php?t=824711
so all credit really goes to him I just wanted to make a special version for rogers users that walk them step by step because it's really easy if follow a good instruction
ok first you need to use root explorer having your device rooted you better know what that is or you shouldn't have rooted in the first place!
1) inside the root explorer go to system/default.prop
and change the following XXXX-XXXX in the following three lines from whatever number in there to this number: 1233-6929 (DON'T USE OTHER ROGERS CUSTOMIZED NUMBER BECAUSE THEY AREN'T WORKING THIS IS THE ONLY ONE THAT WORKED FOR ME!)
ro.product.name=X10_XXXX-XXXX
ro.build.fingerprint=SEMC/X10_XXXX-XXXX/X10i/es209ra:2.1-update1/2.0.A.0.497/8QFA:user/release-keys
ro.semc.version.cust=XXXX-XXXX
2)for pc companion
type run in the search then enter,a window will open
enter the following line in it:
%programdata%\Sony Ericsson\Update Engine\db\
and delete the folder inside(it's a folder with numbers as name)
for SEUS
type run in the search then enter, a window will open
enter the following line in it:
%programfiles%\Sony Ericsson\Update Service\db\
and delete the folder inside(it's a folder with numbers as name)
3)last step go to SEUS or pc companion update and they gonna show you how to get from there

For those people who already flashed to Nordic 2.1 or some other 2.1 version wish to flash back to Rogers 2.1
1. Make sure you have rooted your device.
2. Install RootExplorer from market.
3. Use RootExplorer and open the build.prop in Text Editor (build.prop file is located at /system)
4. Change the following XXXX-XXXX in the following two lines from whatever number to: 1233-6929
ro.product.name=X10a_1233-6929
ro.semc.version.cust=1233-6929
Save the file after you made the change.
5. Go to /etc/customization/settings and open "cust.prop" with Text Editor, and change the XXXX-XXXX in the following line to 1233-6929
ro.semc.version.cust=1233-6929

Put the phone in the flash mode and update with SEUS should give you Rogers 2.1 frimware.

Thanks for the instructions. I've sucessfully converted from Global Generic X10i to Rogers X10a. However, I had to make some changes before I got it to work. The first time I did it, it didn't give me an option to Repair or Install - just Exit.
Besides changing "ro.product.name" and "ro.semc.version.cust", I also changed the number in "ro.build.fingerprint" (which is also in build.prop) to 1233-6929. I also went and deleted the old firmware from the SEUS db folder, as stated in the original post.
I might as well say what "branding" it includes:
- Rogers splash screen on bootup. Now it's shown after the SE logo animation. It's kind of long, actually. I wish I had saved the old one (which was just the SE logo).
- Rogers "My Account" app is included. This app is also downloadable from the Market.
- "PlayNow" app has been replaced with "urMusic" app. This also appears instead of "PlayNow" in Mediascape.
- "Creatouch" app is still included (which is the only app in PlayNow that can't be downloaded from the Market, I think).
- Rogers APN settings are included and enabled by default. No need to manually enter them.
