^ Mine's an AP set as well. Flashed with SEUS with no problem
But now using FW R1FA037 flashed using A2uploder. You should try that too.

^ I flashed using A2Uploader because I wanted to update to FW R1FA037. I can only update up to R1FA035 if I used SEUS. And it's much easier using SEUS .

BTW, SEUS will look for the latest FW and flash it if there's any available. IIANM, updating with SEUS will not delete your themes but I'm not sure about your contact list and the rest. Better backup all those first before flashing just to be safe.

^ Glad to hear that. IIANM, the R1FA037 FW is actually just a branded R1FA035 made available for certain region. For example :- Orange, 3, Vodafone. But I just flashed it to R1FA037 anyways out of curiosity and found it to be a little bit faster. Or maybe it's just a placebo effect.
