Japanese carrier: EM Mobile S21HT

[musato]

I'm wondering if I can use CDMA roms on this site with a Japanese phone? Hoping to flash a WWE version as my Japanese is less than perfect. I know that EM Mobile(sometimes e mobile) uses a 1700MHz band different than the one in the states, its WCDMA and HSDPA.

Asking because I see lots of Sprint/Telus specific ROMS, I'm not sure if thats just software or ESIM/etc related??

If it matters I don't need to switch providers, I just want to use this phone, on my current plan, with an English OS.

Cheers and thanks,

Alexander

are you CDMA or GSM?

[musato]

It's a CDMA, but a bit different than the standards in the states: WCDMA (http://en.wikipedia.org/wiki/W-CDMA) I can get 7.2Mbps downspeed with HSDPA, not sure if that matters or not.

um, id have to say i wouldn't use these roms to be safe.

I was under the impression that WCDMA was actually a GSM band. I honestly doubt it would work either way though.

[cornelious2]

if the phones goinna be a paper weight either way try it, but if you can get some value out of it or use it in some form I wouldn't. is it a Japanese htc diamond?

I just found one guy over on XDA who is with the same carrier, using a ROM for the HTC Kaiser, but seems to be because it has a radio compatible with EM Mobile, http://forum.xda-developers.com/show...ighlight=s11ht

I'm not sure if the kaiser has GSM/CDMA versions, but I guess this gives me some hope for something to get worked out in the future.

kaiser is only gsm (in america at lease). what is your phone type? That is more important than anything.

If by type you mean model, then its a HTC Touch Diamond.

If you mean GSM/CDMA, then i'm pretty sure it's CDMA, it's got the curved "lip" separating the screen from the hardware buttons: seen in the photo/ad I'm attaching to this post.

The installed stuff is:

ROM: 1.73.881.7 JPN
ROM Date: 09/22/08
Radio Version: 1.04.25.04
Protocol Version: 52.36.25.21H

It's got a smooth back (non-faceted, looks like a black Sprint Diamond basically)

[cornelious2]

its got the camera on front by the looks of it. I honestly have no clue, I would ask in xda-developers as this version of the diamond though the case is curved, looks more like the gsm style given the front facing camera.
