Is it the Build or the phone???

Firstly, Thanks to all who have posted clear directions that have gotten me this far. I have flashed a few different builds looking for which suits me best but the problem that I have been running into is data connection. My phone has been able to recognize HSPDA and 3g etc but cant do anything with it. My research has brought to the conclusion that it might have something to do with PPP or RMNET. For example purposes, for the moment im using MDJY Evo Sense Revolution 2.3 on a TMOUS with 2.10.50.26 Radio and using wi fi when i can. Thanks in advance to all who decide to lend a hand.
If data works fine in WinMo, then it is definitely the build.

Ram-Cleaner and Wifi-router app??

Hey folks,
Do you know if there is a Ram-cleaning tool for WP7 available?
I heared it is based on ios, so maybe it won't need but anyhow it will be nice to get new performance again .
Same question with the wifi-router app, is still nothing available?
there are like 14000 apps in the market...
Thx
Ram cleaner? Nit sure why you would need to wp7 does a great job handling it, as for WiFi router, no nothing yet, I suspect it would need to be an ms app, and they are at the mercy of the networks sooo, don't hold your breath

Japan E-Mobile HTC Aria (S31HT) users thread

Hi all,
this is my first post here at XDA Developers and I wanted to create this thread to serve as a meeting point and information repository for all HTC Aria (S31HT) users living in Japan and using E-Mobile as their provider.
I just bought a non-Japanese HTC Aria (oops, as it turns out; wrong frequency support as E-Mobile uses symmetric 1700MHz!) and plan to shortly move to the E-Mobile network with one of their Arias, in order to use the tethering capability they provide for tablets such as the iPad2, Xoom and other wifi capable devices.
It was in finding out more about the Aria I already bought that I came to this forum trying to find out how to root my phone. The Aria I bought shipped with Android 2.2 and HBOOT 1.02 which meant I had no luck in rooting it via software methods.
So I have just ordered an XTC Clip device in order to hardware root my Aria (and any subsequent HTC compatible phones I buy).
I will make this service available to other Japanese users of XTC Clip compatible HTC phones, once I have successfully rooted my own phones and am comfortable with the process. In order not to upset the forum mods, if you want to avail yourself of this service (once I'm offering it) please send me an email privately for further instructions.
Once I root my Aria I plan to begin testing CM7 on it and providing useful instructions to other Japan-based Aria users on the best apps, settings and builds to use to have a good experience on the E-Mobile network.
Feel free to chime in and add your own experiences and tips so we can make this a locus for Japanese Aria development and information for everyone to avail themselves of.
I look forward to meeting you all, and thanks for such a fantastic resource XDA Developers!
Cheers from Tokyo,

Update 15 May 2011 - My XTC Clip arrived and I successfully rooted the Aria and installed CyanogenMod7 plus an updated radio stack on it. If anyone in Japan wants their HTC smartphone rooted to S-OFF please contact me via PM for more info.
I will update this post as I discover new additions to make the Japanese HTC Aria experience as good as it can be. Feel free to suggest other apps by posting their names and descriptions in this thread.

I received my XTC Clip the other day and have successfully rooted my non-Japanese Aria (which had HBOOT 1.02 on it). Transitioning to HBOOT 0.57 via first flashing the original AT&T ROM, I'm now running CyanogenMod7 nightly build 78 on it and have also flashed the radio firmware to the latest 47.63.35.21U_7.16.35.11 from this thread.
Loving the new CyanogenMod7! I'm now in the process of figuring out all the best software and keyboard apps for Japan and the more advanced stuff like CPU clocking etc.
The next thing is to get an E-Mobile version of the HTC Aria, figure out the differences (especially the radio which seems unique to the Japanese market unless anyone knows differently), then do the same procedure.
I could root my aria(E-mobile) with Xtc Clip.
I'm using CM7 now. It's wonderful!!
Yes, CyanogenMod7 is amazing compared to the stock HTC Sense isn't it! Am following the nightlies closely to see how close we are to 7.1. I have a feeling it won't be long....
I could use NTT Docomo SIM with my rooted ARIA(emobile).

Thread will be stickied for the time being
Thanks for the sticky Orb3000!
Hopefully this can become the goto place for all Japanese HTC Aria owners to discuss rooting their phones and using them to their fullest.
With the latest nightly of CM7 I'm getting awesome battery life (3-4 days!). I was in Yodobashi Camera recently with a friend (showing them the Aria) and helped the E-Mobile staff diagnose a connection problem with the store's wifi hotspot! Used my Aria and the Wifi Analyzer app to figure out the least crowded frequency to use for them.... the guy was amazed and quite curious about CM7 being on the phone!

Interesting.. I am also in Japan and been using the Aria. Been dying to root it.
Can you help out (I am in Tokyo area).

The newly released AlphaRevX beta should work on your phone:

Just a quick update - I'm currently testing my old Softbank iPhone Black USIM in my HTC Aria and it appears to work with the "smile.world" APN. I get the proper 3G or H icons depending on my location and my @i.softbank.jp email appears to work fine (IMAP based). Briefly used tethering with my iPad to confirm it works - yes, it does
Will do more comprehensive tests in the next few days and report back again. Going to keep a close eye on the bill to make sure I'm not getting screwed out of my pakehoudai plan from my iPhone.... but from other reports I imagine I'll be fine. Still better safe than sorry!

What version Hboot is on the Japanese HTC Aria?
To be clear, I'm currently using a non-Japanese Aria. But I did go and check the Japanese E-Mobile Aria in the store to see what HBOOT version it had. It had HBOOT 1.02 on it and Android 2.2. I also noted its radio version ends in .13 whereas my Aria (from Hong Kong) ends in .11 (probably because the E-Mobile Aria needs to support the 1700MHz band which the Hong Kong version doesn't support).
Anyway, I've attached a photo I took of the E-Mobile Aria bootloader screen in the store, along with two snapshots of my own Aria running with my old iPhone Softbank USIM in it.
So far so good - it shows the SoftBank provider logo on the lock screen, shows both the 3G and HSPDA icons depending on reception area, handles SMS and MMS perfectly with no additional setup and finally, handles the i.softbank.jp address without issue through K-9. Only small issue appears to be lack of PUSH support for that account at the server end, however it DOES pop up the SMS alert like on the iPhone to let you know a message has arrived, so it's not a big deal (and I don't use my i.softbank.jp address for much since I have my own domains). This is all using the smile.world APN which automatically shows up as one of two APN options when the SoftBank USIM is installed (first time you need to select it, after that it remains on it).
For now I may not even need to go to E-Mobile, depending on the next few days' testing to make sure I don't lose my 'pakehoudai' status and that tethering my iPad doesn't cause any wrinkles! That said, I plan to keep this thread for all Aria users in Japan regardless of carrier, so I'll keep posting new info and asking others to add to the info repository when they can!

visceralpsyche
Sorry, I should mention my current build info too for clarity as to what I'm running:
CyanogenMod7 nightly 111
drowningchild kernel 8.7 BFS (using smartass2 with 806/245Mhz)
Radio firmware update 7.16.35.11
+ Google apps package

Paul,
Thanks for the lead on AlphaRevX. It was only today that I finally had the time to meddle with it and it looks like a success to me:
1. Used AlphaRevX on my EMOBILE Japanese HTC Aria to get the S-OFF
2. Used Revoked tool to flash the custom recovery.
I am now free! Rooted.
Now, comes the question which ROM to install. I guess I should be careful here with the radio versions, right?
Any recommendations or should I just go with the CM7?
Thanks.
Oren
My pick would be what I'm running in my sig - the latest CM7 nightly for the Aria along with drowningchild's latest kernel.
One thing to note is that the radio firmware I'm using is for my Hong Kong Aria, which has different radio bands to the E-Mobile Aria (I'm missing symmetric 1700MHz). So I'd stick with the radio firmware that your handset shipped with for now.
Hope this helps!
Cheers

Last q. Do you know if there is a package or where I can find the emobile APNs? I seems to find only 2 on the net, but I remember that I had like 5-6 APNs on the emobile STOCK.
I have the stock backup, maybe I can extract the APNs from there?
Cheers,
Oren

Yeah, just load up your backup, and write down the APNs listed.
Hi,
I have the emobile APN's. Used APN backup tool to extract the APN in XML format. Will PM you the file when I get home.

[q] help hsdpa speed

First of all, good evening to you all and thanks for any explanations.
I have the following problem, until yesterday I installed the following Roma Android Revolution HD 5.1.9, kernel MDJ V22, radio and the respective RIL 04.11_M2 and my download maximum HSDPA coverage has never exceeded 3Mbps.
Today I installed the rom Dogma V3, V22, and keeping the kernel MDJ radio / ril 04.11_M2, suddenly my download is up to 6Mbps aumenteto ??????
I then rebuilt a complete wipe and reinstall another rom but nothing to do with all my rom is slow while HSDPA Dogma no!
Does anyone know give me an explanation on this?
Dhd I use often as a modem connected to your PC and the download speed is very important for me and I would also like to keep the Android Revolution HD
Sorry for my bad English manages school
Nobody knows anything ?????
I think it's a problem of any energy savings that reduce the performance
3g signal because I have also noticed that the rom Dogma also has a better signal reception and slightly more stable.
The problem is that with this rom difficult to arrive at night with my use while ARHD get there safely.
Not every ROM/RIL/Radio combination is compatible with all carriers, I think you are just unlucky that ARHD rom with its RIL/Radio combination doesn't suit your carrier.
I would suggest going to ARHD team IRC channel and see if they can help you, they are very helpful people.
But maybe that you cannot use that ROM with your carrier
I'm not sure if this helps but i've written a thread aboit hsdpa speed improvements a few months ago.
I don't have the link atm but search for "speed up data connection" here in the DHD general forum. I hope you find my thread with this keywords. If not, I'll search the link on my pc and post it here.

Going Russian

So i have my nexus 7 and it runs fine... got a rom on it.. no problems at all..
but i just bought a second one that i plan on giving to family in russia when i go visit them next week...
being a US user, i have never had any issues using the device but i am wondering how i can make it fully compatible for use in Russia...
the obvious answer is to choose russian as the language during setup but thats not enough... half the things are still written in english and all music shown is american...
what can i do to make it better capable for use in russia?
thanks
