[HD2 General] Nighthawk:
Not entirely true, it's all based on the chipset that is being used and if a particular band is available and unlocked. We've seen in the past extra bands being unlocked on a phone that originaly didn't have (supposedly) any additional bands.

The QSD8x50 platform consists of the QSD8250 (HTC Leo) which supports GSM, GPRS, EDGE, HSPA networks while the QSD8650supports CDMA2000 1X, 1xEV-DO Rel 0/A/B, GSM, GPRS, EDGE and HSPA networks. Both chipsets include:

•1 GHz CPU

•600MHz DSP

•Integrated 3G mobile broadband

•Support for Wi-Fi® and Bluetooth® connectivity

•Built-in seventh-generation gpsOne® engine with Standalone-GPS and Assisted-GPS modes

•High-definition (720p) video decode, and multiple video codec support

•High-performance 3D graphics – up to 22M triangles/sec and 133M 3D pixels/sec

•High-resolution up to WXGA (1280x720) display support

•12-megapixel camera support

•Multiple audio codecs: (AAC+, eAAC+, AMR, FR, EFR, HR, WB-AMR, G.729a, G.711, AAC stereo encode)

•Support for mobile broadcast TV (MediaFLO™, DVB-H and ISDB-T)

•Support for Windows Mobile®, Android, and a number of Linux®-based operating systems

•Qualcomm’s hybrid mode alternative solution

I personaly would like this processor, also Snapdragon: QSD8672

The single-chip, dual-CPU QSD8672™ includes most of the above features, in addition to:

•Dual CPUs, up to 1.5 GHz for faster response and processing

•Low-power 45nm process technology for higher integration and performance

•Higher-resolution WSXGA (1440 x 900) display support

•High-definition (1080p) video recording and playback

•Support for HSPA+ networks - 28 Mbps downloads and 11 Mbps uploads

•Supports CDMA2000 1X, 1xEV-DO Rel 0/A/B networks

•Improved 3D graphics - up to 80M triangles/sec and 500M+ 3D pixels/sec

What I am trying to find is what GSM, HSPA bands the 'chip' supports, hard to find...
[HD2 General] MonnieRock:
Hello,

Not that I have any experience with phone platforms but, my logic tells me, It is all the same system boards and the bands are "set" at the factory. I can not imagine that a different system board is used for different bands.

My real question is, is there a technique to change these bands other than at the factory?

Thank you,

Monnie
[HD2 General] Nighthawk:
They can disable/enable bands on a chip if they want too by a lot of different methods (software, not connecting pins etc.), assuming the chip is capable of using the bands. Now, not every phone chipset is capable of handing more bands than what is listed as specs by carrier, but... As I said earlier, there have been phones that were capable of using more bands than originaly listed (spec'd) and those bands were activated at a later date.

One way to keep a phone exclusive is to restrict what band it uses.

A simple example of this would be the 802.11n registry fix on HD2, all it took was a registry entry to enable it (chipset was capable, just not activated by HTC).
[HD2 General] jmirabil:
No HSPA on the HTC HD2? rediculous...

Hi all,

I switched from a HTC Advantage x7500 class device which is 2 years old, and it did HSPA no problem.... I saw a "H" (for HSPA) in the top menu bar icon for data connect. Now with the HD2, a newer phone from the same manufacturer, all I get it "E" (for EDGE) on the same networks. LAME.

If thats the case, and EDGE is the best we can get on this phone where hspa worked clearly before, then HTC really blew it on this and this phone is a big mess-up to put it mildly. I was going to standardize my entire workplace on this phone--but not with this crippling limitation... rediculous.

Can anyone get around this with a piece of software/registry hack? I am appalled...
[HD2 General] kilrah:
What about "wait until it's released officially on your network"? Then you'll get a version that can.

There's more than chipset, rom settings etc to getting compatibility on a band. Power amps, filters, etc... which are strictly hardware defined.
[HD2 General] jmirabil:
Why would a manufacturer make their radios WORSE or at least LESS COMPATIBLE in a newer model than a previous flagship version and lose something so data-critical like HSPA support... makes so little sense when making unlocked phones.
[HD2 General] kilrah:
Because there's not enough physical space available, because it's significantly more expensive, because the chipset doesn't support it, because you don't want parallel imports, for licensing reasons,... many possibilities.
[HD2 General] mazzarin:
I'm inferring you bought a phone that isn't native to your market.

Odds are that you simply bought the wrong model. I'll guess you bought a T8585 instead of a T9193 (look on the back, at the bottom you'll see a T and a NextG icon.) If 3G matters to you, sell the 8585 and buy the 9193 and you'll get the 3g you so desire.*

*Unless you're in Japan, or something :)

I like the idea of buying a handset without doing research or have a proper understanding of it before hand.
[HD2 General] GodfatherSadri:
Go buy an iphone... it's everything u would want in a phone.. you don't need any knowledge at all b4 buying one.. looks like that's what u would be needing. =)
[HD2 General] skrachmo:
I will pose another question.

My htc pure will not go past 1.5 mbps hsdpa.

The phone comes with HSPA 7.2 ready built.

Eventhough AT&T has opened the 7.2 to be used used with

HTC Aria & Samsung Captivate which are running in speed tests beetween 3.2 mbps and 4.0 mbps. My pure refuses to work at such a speed.

My question is...

Is there a way for me to manipulate it with new configuration, or is is automatic, therefore being blocked by AT&T.

if anyone has any good advice, please write
[HD2 General] rp-x1:
7.2mbps is theoretical, i.e. if the Gods are having a good day and all the planets are in alignment, then maybe, just maybe, you might get 7.2Mbps*

If it is stuck at 1.5Mbps, it sounds like a limit imposed somewhere as its a bit too rounded a number to be to do with distances, angles and interference. It could be your local cellsite isn't capable?

*it'll depend on things like distance from cell and stuff like that too.
[XPERIA X1 Q&A, Help & Troubleshooting] 5udhir:
hi, i live on toronto, canada and i got an x1 from craigslist for 400$ like 2 weeks ago. i like it but i really want to have one of these custom roms on it. i plan to use the EnergyROM "Phoenix 2" 21877. but i have a few questions first.

i use a pay as you go sim card, and wanted to know if flashing my phone would remove my free incoming text messages, 1cent/min after 8pm calling, and other features that i have activated from my service provider(rogers wireless canada) another thing is that i do not have a data plan, but i can get unlimited wireless web surfing($7 a month), will i be able to use google maps with that, since it is different from a data plan?(currently i can use google maps with my wi-fi)

I already downloaded the custom NRGrom and there are 2 files in the archive. one is the kovsimg.nbh and the other is customRUU.exe (what is that?) . do i need to install any other programs to flash to this rom? i have windows mobile device centre on my pc already.

i read the tutorial ( http://xdaforums.com/showthread.php?t=446070) and one of the steps is to run X1_HardSPL.exe

what is that? the rest of the tutorial seems easy enough to me. if anybody would help it will be appreciated, thank you!

Also, any recommendations for ROMs that perform the best would be appreciated!
[XPERIA X1 Q&A, Help & Troubleshooting] ipporek:
You'll need to flash hard-SPL before the ROM. That's what the X1_HardSPL.exe is. More instructions on hard-SPL here.
[XPERIA X1 Q&A, Help & Troubleshooting] 5udhir:
what about the features of my service plan, will they still be okay? do i remove my simcard b4 i do this?
[XPERIA X1 Q&A, Help & Troubleshooting] Nullstring:
Don't worry on those.

Your service provider didn't make any special configuration in your phone's operating system just to have those "free incoming text messages", etc.. The features and those packages configurations are setuped in your service provider's System.

If you want to upgrade, make sure you HardSPL'ed your x1 first like what @ipporek said..

AND FOR SAFETY AND PRECAUSIONS.

Make sure you removed your SIMCARD and MicroSD card before flashing your phone.

PREPARATION FOR FLASHING YOUR X1

It's not really necessary to to flash your phone by saving .NRG file in MicroSD card. You can do this be connecting your X1 in your computer using USB Cable and Make sure you have Windows Mobile Device Center (sorry, I use Windows 7, probably Vista users using different one?)

HardSPL'ing

once succeeded, you can flash different ROMs in your X1.

CustomRUU.exe

is a program used for installing/flashing ROMs in your X1

.NBH file

Chef's provides .NBH files.. this is an image (ROM) file which contains the cooked operating system. Once downloaded, make sure you renamed it "signed_ruu.nbh".

Make sure SIGNED_RUU.NBH and CustomRUU.exe are located in one folder.

hello,

I would first like to apologize for my English I'm french ^ ^

voila my problem is that the A-GPS enabled though this one does not connect to the aid of research, I have not found an answer to this problem so I just see you for information on the issues .
[HD2 General] anx7501:
Hello all

As the title suggests, fhis setting will improve battery life, but is usefull for USA users only. I decided to put this in a new thread to make it easier to find, I have been going nuts over battery life. As you can tell from my name, I am an athena owner who just got my HD2 about a week ago - but got better battery life out of that huge phone than I do with the HD2. I started reading post after post re battery problems, some got good life, others bad. One who reported good life had it in airplane mode and I realized that the data bands on the phone are useless stateside - we can only use EDGE over GSM. So I made the following setting changes...

Go to comm manager

Tap on phone (NOT ON/OFF SWITCH)

Go to Band at bottom

Change top from Auto to GSM

Change bottom from Auto to (1900/850) (CONFIRM YOUR CARRIER FRQUENCIES!!!)

This stops the phone from endlessly searching for HSPDA/3G on 2100/900 frequency - this eats battery like crazy. Without making any other mod, my battery now gives me an honest days work. Ex. I took the phone off charger at 7:00 am at 100%, its now 10:30 pm and I have 25% remaing a full days use, I even posted this from my device.

For those with USA ATT or T-Mo, let me know how it works for you. My phone is straight out of the box, no mods or reg tweaks and this single change almost doubled batt life.

Enjoy!
[HD2 General] jdlorinser:
Omg if this works i'll kiss you. I never bothered to click on that band setting, so I didn't even know those options were in there. The only thing I thought I could disable was in Advanced Network settings.
[HD2 General] ambler11:
Good thinking that man! :cool:
[HD2 General] mastrix786:
it give you better battery life but well cost you on webb browsing slow gprs no 3g speed i hope it helps
[HD2 General] jdlorinser:
We are in the US so we can't use 3G on our HD2's. Edge is actually pretty fast on this device, a lot faster than my iPhone 3GS is on edge.
[HD2 General] ambler11:
Admittedly my day has only been a Saturday, but the battery (at 7.20pm) is still showing 70% and I only changed the 'Auto' at the top to GSM...didn't do the rest! Cool! :D
[HD2 General] ambler11:
Full day at work...35% battery left! Looking good!:D
[HD2 General] FunMCRider:
Thanks!

This worked great I did not even have to switch to my Xperia X1 today. I think I will try this on my sony to see if I can push it to a two day of battery.
[HD2 General] ambler11:
9.10pm and it's still at 29%.
[HD2 General] globus100:
Thanks!

I don't know about battery life yet but in the case of bad reception it actually downloads data much better.

When trying to download data it used to constantly fail, but now it works immediately. Apparently otherwise it tries to download in 3g and fails. When there is good reception it knows what to choose but not in the case of bad reception.
[HD2 General] walshieau:
I still can't get over that the US doesn't have proper 3G coverage though... I'm in Aus and our 3G coverage is quite good. Don't have to worry about it switching to GSM
[HD2 General] Raspster:
I know this thread is centered around battery life but does anyone here have the HD2 and using it on at&t? If so, do you have the ability to enter at&t settings to get MMS messages in the new HTC messaging app in the HD2?
[HD2 General] Funk2641:
US is a bigger country
[HD2 General] chribruu:
Isn't the problem that the US use different frequencies in their 3G network than most other countries, and the HD2 that retails now does not support it?

It used to be so with the Diamond/touch pro if I recall correctly.

Installation was easy. Will try this build on a different SD card so my current perfect working version will stay :).. except GPS not working.

Things i have found:

1) Flip of screen not correct (on Kaiser) When you want use Keyboard the screen is up side down..haha

- After Reboot it seems that is working... so the up side down problem is solved. Only when you close the phone it turns not to the potrait screen

2) GPS not working, after first creation of Data. But i use the Fat32/EXT2/EXT2 setup.

3) When phone is in standby (screen is off) he has problems to wake up when you press power. Press sometimes and the screen come up.

Have test it also with mddi.width=320 mddi.height=480 lcd.density=160 with no problem.
[Touch CDMA Android Development] sshark:

Some observations + lock screen doesn't work,.is it supposed to be statIc or can I click on icons to unlock?

Thanks,

[Touch CDMA Android Development] Pandemic187:
Well yeah...to fix this problem you just have to go into sound & display options and deselect the "orientation" option.

This isn't specific to his build. It happens with others as well.

And hey, you said GPS doesn't work, but should network location work? It doesn't work for me, but it was also not working with the last system image I used, even though it worked on that one at one point, so I'm not sure if that matters.

[Touch CDMA Android Development] plemen:
I wonder if the change in functionality for you was caused by a change in basefiles? The only thing that will enable GPS for all builds is some new developments in rootfs by some of the talented devs on this board.

[Touch CDMA Android Development] plemen:
Yes the themes are compatible - you should be able to push them on the image without any issues. My port is of 2.2.1 - I had to add the navigation myself; of course, the day after I release my port enomther releases a new one with navigation included...

LOVE this build but I have two issues:

#1 I tried playing music in my car, but when I plug the adapter in, sound still comes out of the phone's speakers. How do I make it transfer to the adapter???

#2 Google Navigation loads up, and I know GPS is working because I see my blue dot moving on the map but it still says searching for GPS and thus nothing works.

Any ideas folks? The music thing is more of a bummer, I can live without navigation.

Thanks guys! and Plemen great work!!!! nice and snappy
[Touch CDMA Android Development] anotherhawkeye:
Navigation is not working in any build yet. GPS receives location info but not velocity or direction, so you'll see your location in the map but won't get any navigation help. I believe srwalter needs to make some change to the gps driver to make nav work. As soon as he does, I'm sure plemen will incorporate it into his rootfs.
[Touch CDMA Android Development] tatnai:
ok, turning off background data will improve your battery problems, but not much if you are constantly downloading an update in the background like I am. what you need to do is open app "modem" and hit disconnect. that will kill your data connection.
[Touch CDMA Android Development] plemen:
I'll have to modify the build.prop which I could upload... but I think most people are using the sqsh via haret so they'll need the full build... I'll upload a fixed version - then you can just replace the sqsh without having to worry about having to redo your data.

I finally decided to switch over to running Android from NAND this morning and love v233c so far. I did have an issue with receiving calls at first. My phone would not ring, and the call would be answered by my Google Voice mail, but my phone's call log showed the calls. Somehow that issue cleared itself up, so I am not complaining.

I did have one question regarding the synching of my GMail. On the previous version of Donut that I was running (from this thread: http://xdaforums.com/showthread.php?t=582810 ), my I would be notified of a new email almost instantaneously on my phone, and sometimes my phone would notify my of a new email even before the website refreshes. V233c does not seem to refresh/synch GMail as often, is there a setting I can change somewhere that controls how often it looks for new GMail?

Thanks.
