Any Way to Roll-Back to 7740 or 7720 from 8107 if I didn't Back-up First?!!

[dmw_4814]

I installed the Mango 8107 update on my Samsung Focus S phone, using Heathcliff74's CAB's method, but I forgot to back-up my phone first. Now, I'm trying to install some themes that voluptuary posted, but they won't install unless I'm on 7740 or lower, and my only restore point/back-up is from today, with 8107 ALREADY installed!

Is there any way for me to revert my AT&T Focus S back to 7740 or 7720 WITHOUT having my back-up?!!

Thanks,

Dennis

I had the same issue a couple days back. I had 8107 and wanted 7720 to interop unlock it. Problem was I had no backup what so ever.

So what I did is I went to the phone specific forums and looked around for a Custom ROM (in my case) but originally I wanted to put a shipped 7720 ROM on there to interop unlock and update though Zune. Also looked for a tutorial on there.

In your case it should be in "Samsung Focus (S)" --> "Focus Windows Phone 7 Development".

As people in my question (nearly entirely the same as yours) answered it is only possible to revert back to an older version (if you dont have a backup) if you flash a shipped 7720 ROM.
(people in the phone specific forum will help you further im sure!)

Good luck

For your (@ OP) case I would just recomment a shipped ROM (7740 or 7720) as this requires you to downgrade your bootloader just once.
If you want a custom ROM you need to perform a lot more actions (aka downgrading the bootloader way further) before you can install that, takes more time and is more risky (not saying "a lot" more but speaks for itself)
