Building a multi frequency chip isnt all that hard. software defined radios have existed for quite some time. basically a simple reprogramming allows it to xmit/rec on a different frequency. the trouble comes in the antenna design. antennas must be designed to work at specific frequencies to be the most efficient at transmitting and the most sensitive at receiving. trying to make a single antenna capable of xmit and rec anywhere in a bandwidth ranging from 700mhz upto say the 2500mhz that wimax uses, is going to make for quite a ****ty antenna at any frequency. When you see the piece of foil antennas in todays phones, they may just look like a simple piece of foil, but a lot of design goes into them to make them work well at the frequencies they need to work with.

I guarantee if you compared the internal antenna of the Euro, AUS and USA HD2 there are slight differences. Ill bet the radio chip in them is for the most part identical, there may be something modified on them to keep people from interchanging the radio roms between them though since that would invalidate any FCC or other country equivalent certification for that phone to operate

Its one thing to run a hacked rom, its something completely different to use an uncertified radio rom. Could cause all kinds of havoc with the cellular network, and get slapped with FCC fines if they could track down your trouble causing phone
[HD2 General] moonchaser:
Yeah that's on par with what I had read, you do well at explaining it. :)

Maybe some futuristic worldphone designer would opt for interchangeable external antenna's... I could live with that :D or maybe multiple builtin foils with a software driven switch between them and the radio... that would be neat. Not holding my breath though...

Interesting on the FCC, hadn't thought of that.
[HD2 General] d0ug:
Thanks, I was just again looking at the spec differences between the euro and TMO HD2s and i really don't know why HTC did not also give the TMO HD2 850/900mhz HSPA/WCDMA to truly make it a world 3G phone. According to the tech specs over at HTC.com, TMO HD2 can already use 850/900mhz for GSM/GPRS/EDGE so the antenna is obviously quite capable of both. The only other frequency the TMO HD2 has to handle that the euro doesn't is 1700mhz

Part of me thinks it was probably done so the HD2 couldn't be used over on AT&T
[HD2 General] Svegetto:
It had nothing to do with AT&T, it's because there's a difference between Edge and 3g radio frequency. More than that, there is no phone radio chip that supports all those frequencies and even more so, htc doesn't manufacture radio chips, they purchase them and put them in their phones....just like the majority of the hardware
[HD2 General] Shane1975:
Srs wow hd

How do you get SRS WOW HD downloaded onto the HTC HD2?
[HD2 General] tai4de2:
I think this is incorrect -- the 2100 band support on the HD2 is in fact expressly intended for 3G compatibility in Europe/Asia, and people have reported being able to get 3G in Europe with their US HD2.

1700 == US-only 3G

2100 == Europe, Asia 3G

What's missing, I believe, might be 3G support in certain areas of places like Latin America which may follow US frequencies but don't have T-Mobile USA there to provide 1700 service... e.g., no 2100 and no 1700 either.
[HD2 General] jasecloud4:
T-Mobile U.S. uses both AWS 1700mhz and 2100mhz for 3G. The 2100mhz band is used for transmit and 1700mhz is used for receive. Hence the incompatibility with other carriers phones that only operate in one spectrum.

Cheers.

[HD2 General] Blairware:
Yes, But?

So, as explained by others,

in excruciating detail

this IS only part of the story. I just knew if I posted my question here at XDA I would get the real answers I was seeking.

SO, yes I was disappointed, but I now know why the situation is what it is. Which leaves me with only one glimmer of hope:

T-Mobile USA: Lets get the HSPA+ out to the rest of the market please! (actually you can take your time, but ONLY AFTER you take care of Raleigh Durham, NC - LOL!)

Which leads to one addition question: Does HSPA+ do ANYTHING for RANGE and COVERAGE? The speeds sound wonderful, but if the coverage remains as spotty as the existing 3G is, it isn't going to be a game changer, at least not in this area.
[HD2 General] tai4de2:
Ah.

So we can take our TMOUS HD2s -- which have full support for 2100 -- and use them abroad and get 3G...

But people with phones with 2100 support from abroad cannot use them with TMOUS and get 3G.

Do I have that right?
[HD2 General] gsvnet:
That's correct.
[HD2 General] acessford101:
I have searched all threads, please help or at least respond.

Hey there, i am very familiar with android and switched to the hd2 shortly after it came out. I have been fairly happy with the phone its self. The problem that i have is that my phone its self does not seem to have the 1700 band at all. The closest it has is 2100-900. I checked in the connections settings, and i went into the registry to see if it was there, both dont reflect it. And yes it is a usa tmobile phone. I have also tried several roms and last night even put a stock rom on it and it still dosent show it. THANK you in advance for any replies:confused::confused::confused:.
[HD2 General] Svegetto:
I'm quite sure this is completely incorrect.

But this is indeed correct. This is due to the fact that the HD2 has Band I (2100...which lets you use 3G in europe) and Band IV UTMS (1700/2100 which lets you use 3G in USA on tmobile). This is why european phones won't be able to use tmobileUSA 3g on the 2100 band (because they only have Band I). (Note that if you had a phone that only had Band IV, you would not be able to use 3G in Europe...though I'm not sure if they make such phones/radio chips).

(Also note that htc has been saying that the tmoUSA HD2 will not get 3g in Europe via emails to those who ask, however those that respond to the emails are not the engineers and would not be the first time they are wrong...nor the last).

So, when it comes to things like "Range" that depends. Tmobile's 3G (HSPA+ including) operates, as stated previously, on very high frequency of 1700/2100 when compared to something like the 850 frequency of AT&T. This has benefits and drawbacks. High frequencies are able to go further (so a bigger radius from the tower) but low frequencies penetrate much better. So "range" depends on whether there's something between you and the tower. For, example, if you're in the middle of an empty field, high frequencies would be preferred, but in a city, low would be better so that you be able to maintain the signal in buildings better.

On a side note, I'm actually in Durham/Raleigh (RTP) for the summer, and I just did a check on dsl report speed test, and I got 1541kbps (from inside of a building) which is HSPA+ speed.

This is not possible. If you bought the phone from tmobileUSA you have 1700/2100 (along with the other standard bands that come with the phone). I believe what you might be referring to is the Settings>Wireless Controlls>Phone>Band tab, which is old and incorect (simply not changed by htc). This is also true for the reg settings. Also note that cooks can make that say pretty much w/e they want; this is also true for registry. If you've ever seen your phone say 3g or H in the USA, then you most certainly have 2100/1700 and if not, then you're in an area without 3G, you have a messed up taskbar that's lying to you, or a broken phone.
[HD2 General] acessford101:
Thank you

Thank you for responding, i have been using the 3g and h networks since i got the phone. It completely skipped my mind that even if the software is named wrong, the hardware will still still work. Thank you.

Also on a side note, would you happen to know of any thready regarding best/optimal registry settings that might help the speed of data / Internet. My current speeds on both 3g and h aren't all that good.

Thanks again
[HD2 General] tai4de2:
Hopefully the next batch of phones HTC produces start to be pentaband HSPA.
[HD2 General] hassan023:
can't you swap the 3G chip with a 850/1900 3G chip radio, its hardware so I was thinking if its possible to take it out and replace it with the desired radio chip??
[HD2 General] sirphunkee:
possible in theory, but you would also then need somebody to write you a set of drivers (radio) to make it work with HD2 ROMs.
[HD2 General] DaveNavy:
I know its been a while since this post started however, I can say this remember the old at&t tilt?...It was a at&t handset the box nowhere said it was capable of t-mobile data network frequencies however I flashed a custom ROM to that and was able to pick up t-mobile Data Network I think that it would be more cost efficient to generalize the Radio chip in SIM card phones and just use specialized ROMS and Radio's on the Software side , that is definitely what is going on in the case of the Vibrant its set up as a t-mobile band devices however you can get into the operator menu and enable at&t 3G, I think the Hardware is most likely there, its just up to us and the developers to get crackin like back in the Day....XDA used to come out with HSPL with SIM unlock and lots of other cool modifications...For some reason the popular thing to do now is to flame people for asking hypothetical questions that are both creative and would benefit the XDA user community,...So please don't flame people anymore for asking good questions Lets Get our devices exactly how we want them that's what this forum is all about right?:D
[HD2 General] stevedebi:
No one is saying it isn't possible to cross the two networks - just not in 3g. EDGE will work fine. The 3g is hardware specific, so there is nothing anyone can do to change the high speed between networks, unless one wanted to open the HD2 and try and swap out hardware, which is not cost effective.
[HD2 General] juiceppc:
I have some Mortscripts that I have as a quck link but they all show up with the same ugly script icon. Anyone know how to change these?

Thanks. I searched but couldn't find anything...
[HD2 General] elburna:
Im sure you have put the MS directly into startmenu, right? Make shortcuts of them which you put into the startmenu folder (just like you do with programs) and you will be able to change them.

Greets
[HD2 General] juiceppc:
Sorry but how do I "change them" actually. I understand how to make the shortcut in Programs but how do I actually change the appearance of the icon in Sense?
[HD2 General] elburna:
Ahh now i know what you mean (i think at least :) )

- Use p.ex. JWMD Icon Changer (and of course any desired icon png with resolution 128x128 you can find here in the forum or via google),

- Change the Icon,

- Clear all files in \application data\htc\proglauncher (because thats the cache for the shown icons, if u leave it nothing will change),

- Softreset your Phone

Now the icons should have changed

[Touch Pro, Fuze General] knox203:
Can anyone help explain this??

I have a 8GB ADATA MicroSD card that works great in multiple different Tilt's and Tilt 2's, but not Fuze's.

When I put the SD card in one of the Fuze's I get the Storage Drive option, so it obviously recognizes it, but I do not have the "Storage Card" option when browsing in File Explorer (yes, I unplugged the USB cable before checking). It is the same behavior across all 3 Fuze's I have here.

Again, the card works great between the Tilt's and Tilt 2's.

Weird.......
[Touch Pro, Fuze General] shortaznman:
well it might be because the fuze doesn't support 8gb micro sd cards. It will show that it is there, but you might not be able to use it on the FUZE. I'm not sure how much it can actually support, but i'm using a 4gb microsd.
[Touch Pro, Fuze General] stylez:
Fuze supports 16GB and pretty sure even 32GB cards the issue will be class for some reason class 6 cards can be a problem.

My 8GB Class 6 has same problem Kaiser/Excalibur reads it but not Touch Pro.
[Touch Pro, Fuze General] knox203:
Mine's class 6 too, stylez. I wonder if that has something to do with it.
[Touch Pro, Fuze General] sb.oddworld:
Hi, I'm new to the forums. It's only an idea, as I have read alot of comments across various websites that the Touch Pro does not support Class 6 cards. But you could maybe try the Panasonic SD Memory Card Formatting Software Ver.2.0. It won't do no harm. :p
[Touch Pro, Fuze General] Farmer Ted:
I would try re-formatting the card as well. If a simple re-format doesn't work (just use a card reader to do it on a pc), then you could try different cluster sizes. You can get a demo from www.softwinter.com that works really well.

[Android Software/Hacking General [Developers Only]] seankk:
i was wondering the same thing im getting one today but my friend has one and there is no debbugging mode in settings i dont know if this will be a issue or if im loking in the wrong place iv have several android phones and rooted them all, so i didint think it would be so tricky to find debugging

UPDATE

i found debugging mode its in the usb menu....i guess im just curious about root...
[Android Software/Hacking General [Developers Only]] taylorn8369:
I just got mine today. The USB drivers from motorola work, so we can play around in ADB. I hope for an easy root, but I have a feeling the i1 shares alot of hardware with the backflip and or the cliq XT. I don't think either of those have root yet, so I don't know what our chances will be.
[Android Software/Hacking General [Developers Only]] seankk:
i was thinking the same thing...
[Android Software/Hacking General [Developers Only]] taylorn8369:
Has anyone figured out how to get into recovery or fastboot yet? I have tried every button combination i think and have not yet found it.

I did some how get into a diagnostic type app on boot (tested screen colors and touch calibratsion) but I have been unable to replicate that.
[Android Software/Hacking General [Developers Only]] taylorn8369:
I am pretty sure we are SOL when it comes to root. I tried to run flash_image recovery from adb shell to push a new recovery img to the phone and it dies saying can't find recovery partition.

Unless it is possible to mount the system and writable with a custom boot.img I don't see how this could be done.
[Android Software/Hacking General [Developers Only]] Laph9979:
I 2 just bought the i1 and can't wait to push a new flash. I hope we are not SOL and that some1 more experienced then I will show us the light and find a way.
[Android Software/Hacking General [Developers Only]] taylorn8369:
I am confident I could get us a root, I just need to find a way into recovery. Or fastboot for that matter. In your free time guys, reboot while mashing different button configs to see if you can find it.

I tried to push a custom recovery but adb said recovery partition not found. So either there isn't one (I hope this is untrue) or it has a different name.
[Android Software/Hacking General [Developers Only]] rubensbasket:
Rooting !!!

Hold the green send key and the center key on boot up you get a screen that looks like it would be fastboot but the device doest show in fastboot devices from the SDK.
[Android Software/Hacking General [Developers Only]] navyguy:
Is the Moto i1 going to get its own forums on xda? Who decides/creates the forums?
[Android Software/Hacking General [Developers Only]] taylorn8369:
Is there anyone with experience making android apps?

I have found that /data/local is read/writable so I put the su bin in that DIR and installed superuser whitelist. If in ADB shell I run /data/local/su the superuser app asks for permission but fails because it is looking for su in /system/bin.

I am trying to compile the superuser app from source to have it look in /root/local, but the build is failing. If we can get that then we should be able to remount mtdblock7 to /system as read/writable and put su where it belongs.
[Android Software/Hacking General [Developers Only]] taylorn8369:
Thank you for copy/pasting my post from another thread.... With that possible fastboot though, I know fastboot has had some issues with drivers in window7 64. So can someone try that on a XP machine and see if it shows in fastboot devices?
[Android Software/Hacking General [Developers Only]] Laph9979:
I am running x64 windows 7 also so I guess my button mashing has been in vein... looks like we are on the right track though...

I am guessing we won't get a forum for the Moto i1 Until it get's rooted, as I don't see people being to interested/developing/hacking for it until then.
[Android Software/Hacking General [Developers Only]] izzystylez:
hope u guys get ur forum . i luv boost!
[Android Software/Hacking General [Developers Only]] Laph9979:
I don't know how helpful this is but messing around I found IDEN phonebook manager from Motorola. Installed it and changed USB communication to Modem and was able to see the phone reboot and read sim data. Check it out and let me know what you think.

here is the link to their site to get and test it out.

http://servicemyphone.motorola.com/iden/support/software/organizer_upd.jsp
[Android Software/Hacking General [Developers Only]] Laph9979:
Ok, so as the previous post states I was able to access my sim card from the program which had me wondering if all IDEN phones from motorola had a special way of flashing so I looked around and found this link:

http://servicemyphone.motorola.com/iden/support/software/html/firmware_utility.html

I found a firmware update for my old boost mobile i776 and downloaded upon running the program I noticed it launched a program called Iden upgrade utility. I am now thinking that is going to be our ticket into the phone.

Again let me know what you think.
[Android Software/Hacking General [Developers Only]] RotKT:
how to do the hard reset this phone i1 (with password)?

thanks
[Android Software/Hacking General [Developers Only]] Laph9979:
This was all I could find. If you get the external figured out let us know...

https://motorola-global-portal.cust...2560/~/i1---factory-data-reset-(master-clear)
[Android Software/Hacking General [Developers Only]] taylorn8369:
the password for the master reset is 000000
[Android Software/Hacking General [Developers Only]] taylorn8369:
I don't have that phone anymore so I can't test this. But try to boot up while holding green button-center button-red button... That will take you to a flash utility screen. I thought it was fastboot, but could never get it to recognise in the sdk tool kit.. see if you IDEN tool will recognize the phone when in this screen...

I also found that if you ope a terminal emulator app on the phone (or adb shell) and execute

/system/bin/mtd (i think it was mtd) you get some other kind of diagnostic tool on the screen. pressing different buttons will show different command options. I never figured out what this was for, nor how to do anything with it.

if you do a /system dump and look at init.rc it has a reference to ota script and it having su privelages.. if there is a way to piggy back a ota command, that may be another ticket in..

I hope some of this information is helpful to you guys.. Good luck!

every time i get "./exploid not found"

so no good on the root.

i get the same error

"./exploid not found"
[Android Software/Hacking General [Developers Only]] cyberplague:
Ok so I tried the root as well. Got the same file not found error.

So I copied all the files into the sqlite directory chmoded as needed and ran exploid.

File not found error is gone, but now I get a cannot load libbinder.so

So I went searching on the device and it is not in the lib directory or anywhere that I can find on the i1.

So it seems there are more changes needed to the root process then just the code changes birdman did to the droid x root process.

Hopefully this helps figure out what the problem is so we can root this i1!

how can i backup my rom of my i1 before root it ?
[Android Software/Hacking General [Developers Only]] opm:
I don't think that is possible for you to backup the whole ROM prior to root. As far as I know, the 2 popular methods are Nandroid backup, which can only be achieved after rooting and loading a recovery file.

The other would be ROM Manager, which requires complete rooting and hopefully has no conflict with your current ROM.

Rooting's MAIN purpose is to load a custom ROM, at this point there are no custom ROM's for this phone. So why root? To run a some root required apps? Not worth killing a $200 phone. Wait until there are enough programs, including a OEM bin/sbf file, before you attempt any hacks or you'll end up with a dead phone and no solution.
