I recently wanna send back SiS to fix the volume button,
but have to flash back to stock rom state.
anyone can share the info?

Just to let you guys know that I'm already get my phone back from htc SiS.
They change a new LCD, a new volume rocker. Screen shine like new yo!

I guess they don't really bother of the software since my wallpaper is just the same like before I send it to them. But too sleepy now to check either my S-ON still intact.

btw guys, can somebody help me confirm that our DHD has only 600 MB memory. Somehow, i think we do have more

lucky lor,
got luxury of time,
i'm my own work report already overdue 
should be less than 3 weeks,
since got mine in that timeframe which also including waiting for screen coming from oversea,
so, if they got stock, should be in 1 week.
got info on the first page,
do check it out!

i've did repair my volume button twice be4 i sold my DHD...and now it happens again..where i need to go with my frens to claim warranty..as i sold my DHD to my friends..my DHD volume is being repair as i refuse to leave my phone there...so they didnt touch the software and all the data inside...but if i replace the volume button maybe they will kacau the data and software inside...

i ask sis berjaya plaza to repair...i ask the technician to teach me..but they just say have dust..which they only buang the dust..and told me i cant do myself..as i didnt want their replacement nokia phone..i just accept it la...the problem repeat after 1-2 weeks..then fed up and sell my dhd..hehehe..btw..still missing my DHD...the built is so tough and holding DHD feel much more premium than my GNEX..want to search aluminium case la for my GNEX..
