[Q] Need Telstra 7.5 Rom for Lumia 800

[Eamon]

I just got my Telstra branded Lumia 800 back from Nokiacare after warranty service and they have upgraded it to WP7.8.

Problem is that I have a backup from 7.5 that I took just before sending it away and I cannot restore it back over 7.8. So what I am looking for is the Telstra ROM image that matches my backup:

These are the details I copied off my phone BEFORE I sent it away.
OS Version: 7.10.8773.98
Firmware: 1750.0805.8773.12220
Hardware Revision Number: 112.1402.2.4
Radio Software Version: 1.7.50.08
Radio Hardware Version: 8255
Bootloader version: 7.41.0.0
Chip SOC: 0.74.2.1

Also, what is the best way to flash 7.5 rom over 7.8?
Nokia Lumia 710/800 downloader (http://forum.xda-developers.com/show....php?t=1665821)
or
Nokia Care Suite
or other?

Can anyone help me?

thanks,
Eamon

This is the worst thing on LUMIA.

There is no way to restore your phone like an iPhone.

Your mail, contact, Documents; anything connected to LIVE account will be restored automatically.

Everything else ( Photos, music, Applications, SaveGames ) will be lost. You will have to re-install/resync once again. (SORRY for the savegames )

So if this is the only thing you are concerned about, don't bother rolling back. Enjoy the 7.8

Thanks for the reply, I was planning to flash back to a stock 7.5 rom, then use zune to restore my backup which would have given me my sms's and saved games, then upgrade again to 7.8 expecting the sms's and save games to survive the 7.8 upgrade. In any case, I've been using it now for a week and have it setup the way I want again so don't want to go through the process again so I guess this thread can be closed.

I'd be damned...

But how do you restore your SMS and Save Games ????

Restoring a backup using Zune puts the phone back into the same state as when the backup was taken, sms's, saved games, settings...everything. Problem was that I couldn't restore a backup of my phone taken before I sent it for service when it had 7.5 on it over the returned phone because they had upgraded it to 7.8 during the service. If I could flash it back to 7.5, then I could have used the Zune's restore functionality to get my phone back to its exact same state as before I sent it for service. I had then assumed (maybe incorrectly) that upgrading to 7.8 would not wipe my sms's and saved games, maybe I am wrong about that as I never when through the 7.5 -> 7.8 upgrade myself.

Just to be clear, I don't have my old sms's or saved games on my phone anymore as I wasn't able to source a 7.5 rom in time to try the process above and now I have built up a bit of history on this phone so I've given up on the older stuff.
