Which RUU to use?

Hi. I'm planning to restore my phone to stock, but I don't know which RUU to use. All I know about my phone is the information listed in the bootloader, which is as follows:
HBOOT-1.17.0000
RADIO-3831.17.00.18_M
anyone can tell which RUU I'm supposed to use by looking at these numbers? The phone came along with my phone plan, I'm from Singapore.
EDIT:
I just found the baseband version, it is 20.72.30.0833U_3831.17.00.18_M but there is more than one RUU file on http://www.filefactory.com/f/0eafb9c43276c308/ that has the same baseband number. Which one am I supposed to use???

select the one which corresponds to your area..

your cid no ??

your cid no ??

This case is already solved.

How can I repair its Baseband.
Thank you very much.

M8 European downgrade from marshmallow to Lollipop

Has anyone attempted to do this. I did it and now my baseband and imei are gone

Not enough info.
How exactly did you try to "downgrade"? List the exact steps, file names, etc.
Do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
Is the bootloader unlocked, s-off, etc.?

need to update htc one m8

hi to all ..i have htc one m8 and i cant update it to marshmallow ..my version in phone is lollipop .. any help plz

Is the phone modified (bootloader unlocked, root, etc.) or stock?
Do you know what version (CID) of the M8 you have?
If you know how, do fastboot getvar all, and post the output (delete IMEI and serial number before posting).

HTC M8 SPRINT has no connection.

Guys...help. My HTC M8 SPRINT has no connection to a carrier. I dial #06# no IMEI. I go to the fastboot mode (use fastboot getvar all) I see IMEI.
looks like radio is bricked. Hot to fix iT?

Did you do something to cause this condition? Tried to flash an RUU, firmware or radio? Is the phone s-off? SuperCID?

For what reason did you reflash that RUU? What was done to the phone previous to that?
When asking for help, it's best to give as much background info as possible; not just a few sentences on the present condition. Knowing the history might give us a clue in troubleshooting.
Also, do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
