NuB with a couple of questions...

Afternoon all,
This seems an excellent place for a new XDA IIi owner to start things off! Please forgive me if I repeat anything or if I am posting in the wrong place, just let me know and I will gladly fix it.
I'm just at this stage trying to get used to the XDA and add value to it by means of software and customisation to the extent I did with my P900 and P910i which I have been using for the past 2 years. In some ways I'm finding it quite hard to get my head fully around the XDA IIi?! I actually started out with the IIs a couple of weeks ago but found it to be way too unstable and too much of a problem so I jumped over to the IIi. So far things have been better but I have a few "things" I would like to ask in the hope that someone can help me.
Erm.. where to start...
1. Ok, O2 branding, the O2 active stuff and the icon in the title bar. Can it be removed? Currently my O2 icon is just a blank whit square, it never displays properly and just makes the phone look, well, pants!
2. The headset supplied with the phone seems awful! I get lots of complaints about volume fluctuating. Does anyone else find this?
3. Can you actually just turn the phone off?? If so... how?
4. When listening to music, I cant put the phone into "sleep" mode, ie turn off the screen whilst still having the music play. Is there a way around this?
5. I use AAC music files too, I have Betaplayer which obvioulsy plays them but I cant make the phone recognise an AAC file and associate it with betaplayer... is this possible? Currently I have to open the player then open the file.
6. Firmware. Gulp.
I updated my P9xx's regularly, not without issue I suppose though! Do you guys recommend regular firmware updates?
Currently I have:
ROM Version 1.10.00 WWE
ROM date 12/24/04
Radio Version 1.00.00
Protocol Version 1337.39
ExtROM Version 1.10.124 WWE
Any advice on f/ware would be greatly appreciated. It can be such an ordeal but if its recommended I would like to do it really.
There are more things but maybe I should be quiet now and see if anyones got any comments!
Any help would be gratefully received and as soon as I get up to speed I will put back into this forum.
Thanks
Fronty.

1) The o2 branding software can easily be removed. I myself have wrtten a couple of replies to this sort of thing and so have others. If you do a search for "o2" "activeUI" "remove", you'll find the steps needed.
2) I've only used the headphones for using the phone once or twice apart from the first XDA I ever had. If you go to start > settings > system > Microphone AGC and enable the auto volume, this may help. Noone's complained about my voice being too quiet or fluctuations since I got an XDA2, never mind the 2i I have now.
3) If you tap the network signal strength, there is the option to "Turn on flight mode" - this is phone OFF. More indepth explanation of this is included in the manuals you should have with your phone. If not, I believe o2 do a .PDF you can download from www.o2.co.uk/xda
4) If you're using WMP10 then I know what you mean. On the XDA2 I used to be able to select the Contacts button as "screen off", but whenever I try this on WMP10 on the 2i it won't map the button. I prefer to use a third party program called Pocket Player 2 from Conduits (http://www.conduits.com/products/player/). It's fantastic, highly customisable and the only drawback is that it's not free. Well worth the money though. And you can turn off the screen and map other buttons during playback.
5) Can't help you on that one.
6) I always update mine once the official update from o2 comes out, though I must admit I've presently got one from the Australian o2 comparable i-Mate. It's a slightly more stable ROM but is sometimes tricky to install. There are instructions on these forums on doing it - I followed them myself. Currently there are NO official updates for you to upgrade to; you are on the most recent o2 ROM. You'll soon know when one exists, if not already from the http://www.my-xda.com/xda2i_soft.html page.
Hope this helps, please post back if you need further help.
Cheers

Screen Disalign? Read this!

Hello to all!
After I've upgraded my Magician to 1.13 I recognized my screen disaligns after 5 minutes of use. The I've downgraded to 1.12, but the disalign still stays. After browsing the forum I've recognized that much people have the same problem too. Some guy says that you should downgrade your ROM, or take the unit to the HTC European Service (if you have guarantee).
After browsing in the registry, I've found a regkey about Calibration. I modified it, and now the machine runs good, without disaligning.
So the method is the next:
1. Open your favourite Regeditor (Resco, Total Commander etc.)
2. Open HKLM/HARDWARE/DEVICEMAP/TOUCH/
3. Open CalibrationData You will see coordinates.
- The first coordinate is always x coordinate, so that is the horizontal
- The second coordinate is alwasy the y coordinate, so that is the vertical
- The first number pair (ex.: x,y) is the center point
- The second one is the upper left
- The third one is the bottom left
- The fourth is the bottom right
- and the last one is the upper right
My screen calibration is:
474,498 814,773 814,228 119,228 119,773
I hope it will help to guys who has the same problem.
If someone finds better calibrate coordinates, pls post it.
Cheers,

cheers for this , I have the same problem and have tried many different tweaks with no result.
My co-ordinates were different but then I was getting a mis-alignment problem I will give your co-ordinates a go and report back.

mine has no issue or whatsoever. working fine since...
my coordinates are:
502,498,862,771 859,223 138,229
hope this helps...

Never got no problems with it.
Coordinates are:
499,503 861,774 856, 231 148,223 142, 773

What a great discovery
Mine is a HTC Charmer (MDA Compact 2) on WM5. My data is very different
1928, 1960 3308, 617 3296, 3316
(WARNING! THIS IS NOT Magician configuration!)

can u tell me more in details pls coz i have the same problem. I must align the Screen oftenly
u wrote : Open your favourite Regeditor (Resco, Total Commander etc.)
Where can i fin this programme ?
pls help. Tks

i found the total comander and do wat exactly wat u say.
But the my problem doesnt solve

calibration data 2020i alpine
i have resive one devise with problems in alighn screen first my thought was that the problem was at rom and the extrom that was missing after lot of trying and with resco registry i found that the calibration data was missing pls pls if any one can help me by posting the coordinates of that device QTEK 2020i

Why don't you ask in the matching topic?

hey guys can you make a permanent fix for the disalignment bug of xda mini?
i have this problem...but i got a solution on this topic,but the problem is when you hardreset the ppc its going back again the problem unless you tweak it again in regeditor...
can the rom developers include this tweak for the upcoming cook rom for xda mini so that the screen disalignment can be fix...
thanks

to HyperMalac:
so, the solution is to change the coordinates with yours?? hmmm ok i will try it.. i (and my friend here) have the same problem. i thought this is LCD problem and cannot be fixed unless u change the lcd (as 1 of the member said) thx~! i'll let you know~!

not working
i have to constantly align my screen and even putting in the coordinates..it still doesn't work. I will be sending it back to the repair centre sooon.

dear all,
I want to ask how to open the registry in the WM2003?
I've installed the Total Commander, but after that I still confused what to do next.
many thanks

Open TC and open the "folder" named: \\. this \\ folder contains the registry...

NEWS:
Finally I've took my Magician to the HTC Europe Service Center...Waiting, for solution....Will post the result
Cheers

hypermalac....
so the reconfiguration in registry do not solve the screen missalignment problem? Coz I've try, but it seems no result, only the frequent of screen become missalign is decrease...
any solution for this?

Well, the registry modding, only reduced the misaligns, for me too. I saw somewhere on this forum that this problem is hardware problem, but I don't think so. Someone said, that the touchscreen has a factory malfunction. Anyway I'd took it to the service, an as soon as I get it back, I will post, if it's solved the problem, or not.
Cheers

@HyperMalac:
well, when u get ur mini back from service centre, ofcourse it will be fixed, no more sreen disaligned, for sure..
now, the problem is, why this happend to many people (from different countries) ?? can you ask the service center while they keep your mini : what is wrong with xda2 mini lcd?? why this disaligment happend? how can we avoid this?? how to fix (without send back to factory) etc etc.. please ask, if possible, ofcoz... thx alot
FYI, this is not the only problem that many xda2mini from difference countries get. other problem is after take the battery out for only 5 secs, you will get HARD reset. the backup battery is not functioning~! happend to me~! then sent mine to factory, they fix it but strangely, they change the MOTHERBOARD~!
ah, i think someting is wrong with HTC.....

Well, when I get it back, I'll ask your questions, if it's possible, and I hope too that the service give some solution for us, to avoid this problem (screen misalignment), without taking our magician to service.
Battery problem:
Changed the motherboard???Do you mean the hardware buttons?
Well, my magician works fine expect the sreen, so I haven't got any batt problem. But I will ask it too.
Cheers

Hardware Issue
Pretty sure this IS a hardware issue. Happened on my MDA Compact and got progressively worse.
No amount of hard resets, software configuration and ROM upgrades fixed it.
Came back from HTC good as new.
I have heard that using screen protectors causes this as it is touching the screen all the time.
I no longer use a screen protector so I'll let you know next year if the problem has come back again!

Can't turn on the bluetooth

hello,
unfortunately i cannot turn on the bluetooth from comm manager, it turns on and after 1 second is off again.
any solution for this problem?
thanks.

I have had this problem before and unfortunately am having it again. Only solution I have ever found for this is a hard reset and then reinstalling all your apps. If you try to restore from a backup from Sprite Backup, for instance, the problem remains. This would lead me to believe that it's a setting or a registry issue somewhere but I haven't been able to locate exactly what would be causing it and don't know enough about programming in WM to write something to figure it out.
Not a great answer but there it is.

Hi, I have a Uk version of the touch cruise and I have the same problem. I just did a hard reset but the problem remains. Turning bluetooth on is impossible. It just try's to turn it on and shuts it off immediately.
Maybe it has something to do with GPRS? I am always connected to the internet. I tried to disconnect but then bluetooth still doesn't work. Can anyone help? Thnx!

No one has a clue?

I had this prob with bluetooth and wifi following the use of wmwifirouter- after hard reset and no wmwifi all goes well...
On a French SFR rom

any other idea?

Same problem... beginning to wish I'd gone all Apple and bought an iPhone. Anyway.... To trun it on, I had to go to Comm Manager>Settings>Bluetooth>Mode>Turn on Bluetooth. That worked despite the Comm Manager still showing Bluetooth as "off".
It only connects 1/2 the time to my headset or handsfree in the car
Otherwise, the phone crashes only once a day! Great! Thanks!

ok, great to see more people having the same problem but i hope that someone has a sollution...
When I try to turn bluetooth on in the communications settings i get a message saying there is a hardware error! :S
Ohw btw, I'm not using any router programs or other and my WIFI works fine.

has anybody of you having this problem tried to change to another rom?
if yes? did this worked?

any news on this?

No news, I don't want to try for a different rom because i don't think it will change anything. It just seems like its a faulty device which is a real shame. I've already contacted the place where i bought it and see if i can get a new one.
I also have problems with my microphone during calls, photo camera does often not work and the touchpad reacts very slowly to my touches. Very annoying!!!!

Yup, am returning mine to HTC aswell. Not even sure I want it back. WiFi stopped working too, and then it stopped receiving text messages, and everyone said they couldn't hear me when I called them. Great

Some of you guys got a bad device, there are thousands out there working properly.
If some of you guys flashed a newer Radio, the one form the test-ROM, then this is your problem.
And some of you guys have a quite gay branded ROM (slow responsiveness of touchpad). The original HTC ROM on the FTP and even more so a cooked ROM would solve alot of your problems. But be aware, flashing without having a backup ready is going to void your warranty if you want to exchange it having a custom/non-original ROM on the device.

What's up Schaggo
I am experiencing the same problem these gentlemen are mentioning and my ROM is not gay or lesbian. It is the original one.
TC is my 7th HTC device and I can see the quality of the ROMs decreasing a lot on every new device. I feel like HTC needs a real competitor to move up its arse quicker.
All I can say is that it really annoys me to hard reset this [email protected] everytime I "accidentally" use a native feature called Flight Mode. By bluetooth seems to fly away and never get back.
Lots of time the GPRS settings have to be reconfigured too. Some people I know have problems with GMail IMAP4 accounts when sending messages after some time. I never had this problem on my Kaiser neither on my Niki.
The lack of a video driver really is an egg on our faces, because I can't believe my ole Qtek 9100 responds quicker than these "all the bells and whistles" Qualcomm 7200 super-duper geared up devices.
So, if you feel like not contributing, please do not mess around.
Your signature tells me you are a wise man, but your comments show me otherway.

Click to expand...

Hi
I've tried many custom rom and the PB continue. "PB with the hardware oh BT".
Hard reset doent change anything.
my initial rom (SFR France) was working
custom rom (blackwidow + Bepe 058) are buging...
nedd some help !

Thanks alot for that input feaps. I guess I have to clarify a little bit.
My answer was supposed to be pointing in different directions. The first and general information I tried to contribute was, that it is not a common Polaris problem to have a broken Bluetooth unit. Which doesn't help at all to ppl affected, but it should tell them, that they probably got a bad device and should exchange it first before blameing htc in general and shouting for an iPhone.
It only was partially directed at specific persons. At madinga for example: did you try hardresetting your device? It could be a corruption in your system which causes all those problems. I doubt it though, if you suffer the loss of so many functions at the same time I suspect the mainboard to be broken. But nonetheless, hardreset it, see if its working, BEFORE you put your backup back on the device again since that could restore the corruption. If it doesnt work, exchange your unit, I hope you'll get a working one back.
My second line was directed at all people which have overwritten their original Radio with the 1.58.25.14 originating from the HTC Test ROM which can be found on the ftp server. The Bluetooth part of that Radio is flawed and leads to the problems described in this thread. I quite nicely pointed that out and told people where to have a look before shouting around. I do know that because I tried it myself and couldnt get my Bluetooth devices working. Once I flashed the original Radio back, my BT problems were gone.
And my third line - in which I may chose the wrong words, 'gay' for example - holds information targeted at people with for example the branded french SFR ROM or the original HTC french ROM. The SFR ROM is just horribly branded and if you go through the threads here you'll find people complaining about problems which then turn out to be related to the ROM. The french HTC ROM is flawed as well, it has severe problems with the volume control. I don't exactly remember what it was, but it's a flawed ROM, thats for sure. The German o2 ROM isnt flawless either, I know that because I originally had that ROM. Once I flashed my orbit 2 with the original HTC WWE ROM, I found it to be working alot better and smoother than with the o2 ROM originally provided. And this is where my last line comes into play: if you suffer problems related to your currently flashed ROM, they could be diminished by flashing an alternative ROM. But if your device is broken, and I personally and strongly believe that everybody fooling around in this forum should be intelligent enough and able to determine the sense of my words, eg. if he/she suffers a ROM problem or if the device just simply is dead and take appropriate actions.
And now to your contribution feaps. I feel personally attacked by your words. Thats why I defended my words in all the paragraphs above. Trust me, I've had enough mobile devices of all sorts to know what it means to get a not working once. Its frustrating and makes you want to throw it out of the window. And being able to see the quality decrease over time is just another drop on a hot stone. I agree. But be honest, if your BT unit works and stopps working once you engage a software based function, the problem is software related, dont you think? As for the GPRS settings, I cant tell. Since I use a free ROM which has the wizard built in (o2 removed it from their ROM) I didnt switch my SIM and the configuration worked, automatically and every single time. And I do use IMAP as well on my personal E-Mail account. Until now I didnt run across any problems, so I cant give you any feedback on that either.
So rethink again if I mess around or not or if I actually try to contribute and help the freshmen, coming into this forum and flashing whatever they find and breaking their devices. And recommending to flash the original HTC ROM, which should be/is the base for everything floating around, breaking your devices, is a serious input to everybody.
Edit: I forgot to add, pointed at nooms, there are cooked ROMs out there which stupidly have the new, flawed Radio baked in. Which Radio are you on? Try Start > Settings > Tab System > Device Information > Tab Version. Are you inadvertedly still on Radio 1.58.25.14 or back to (original) 1.58.21.23?

Hi everyone,
I agree with Schaggo completely. Most of the time problems have something to do with the software on the device. But I a not a tweaker like most of you guys, i've just bought my first (and hopefully not last) HTC phone. If i have problems of some kind, all i can do is reset the thing. A hard reset if necessary. I've done that many times. I can't change the software that comes standard and i don't think i should be the one who has to do that. Shouldnt HTC be doing that??
Anyway, Bluetooth keeps saying it has an hardware error. My radio version is a standard 1.58.21.23 but isnt finding any radiostations here in holland. Is it also broken? (sorry, i know, its a bit off topic)

You're right

Well put. Sorry for being rude, but I keep seeing people offending others day after day in this forum that used to be high level; but that doesn't mean I should act the same way.
I totally misread you and please accept my apologies.
My ROM is: 1.25.405.1 WWE
ROM Date: 12/11/07
Radio Version: 1.58.21.23
Protocol Version: 25.65.30.04H
One thing I could notice is that HTC has a flaw in the Flush HKCU to Permanent Memory While Shutting Down. Some keys are not written.
One example is the MagiCall (an app I use) registration key. The software maker had to write a flush app for doing that. Another example is the Start>Settings>System>Error reporting. No matter what you chose, after a power cycle or a soft reset, it always go back to "Disable...".
I have, also, already tested the device after the hard reset with no extra apps on it. Same lame behavior on BT...
So, SW QA levels are really dropping fast on new HTC models. That is pretty bad.
But anyway, I have an open case with HTC and if I find something contributive I will toch base with this thread.
Once again, sorry for being rude.
Best,

Then I guess you most probably got a bad unit. I guess the only solution at this time is an exchange.
The Radio-Firmware doesnt control the FM Radio btw The Radio-Firmware controls connections to the providers network, Wireless LAN and Bluetooth. But the FM Radio seems to be really bad in the Polaris, a lot of ppl I know complain about it.

No problem dude! There is no need for such an excessive appology. We are in a Forum and people have different oppinions and I think its totally acceptable to shout at each other. I just wanted to express that I'm not in accord regarding your judgement of my post. But thanks a lot, I seriously really appreciate it!
Yes, your device seems pretty standard to me and the scenario you described logically made me think of a software error. But this seems very unlikely now. I'm out of ideas for the moment then, I guess you have to return or exchange it too.
You are perfectly right about the dropping SW QA though. You can notice the registry glitch in other areas as well: backlight timer always reset to 30 sec, and there are more settings all over the place which don't get saved properly.
Again, no problem, everybody lets be cool

Bluetooth doesn't turn on
I have the same problem. Did anyone find a solution?
Also camera fails to initialize, touch pad is sometimes very slow for initial reaction. I have NO added programs beyond manafacturer originals and have tried a number of hard resets. Doesn't help.

[Q] What can I do to a LG fathom

Ok so here is my question
I just got me a Lg Fathom
With WM 6.5.3
Most of the apps, themes and what not are for HTC phone
So my question is very very simple
What can I do to my Lg Fathom?
I want to customize it to make it look hmmmm not so default looking
I see many things on this site but I am very unsure what I can and can't do
Please help me
Maybe link me to a few things that will help me in learning wm6.5.3
thanks
bhast2

Is there anyone that can help me
I would like a custom rom or something anyone point me in the right direction

I am currently also thinking about buying a Fathom. Since its the only available 1Ghz phone with keyboard and headphone connector (no radio and with that not TMC data for navigation though).
But yes...what can you do with it. Ist it possible to run Android like on other HTC phones? What about underclocking the CPU in standby like nuedynamicclock, i suppose it wont work with the snapdragon?

Load androkkid freeware on your fathom. It may give you some feeling that you are running android on your phone
pocketpcfreeware.mobi/download-androkkid.html

Very funny..i'm thinking about this phone because its one of the fes 1ghz, real keyboard windows mobile phones. If id want android i could buy something else...but android sucks..

I dont understand software but have lots of intrest. I was using T mobile wing and with the help of this website I downloaded some kitchen and I have customised my ROM. Now I have again purchased LG Fathom. I too looking for some enhancemnt/upgradations/customisation. If you find something you can let me know.
Sorry for giving you funny answer:

Have you tried looking over at the other place?
(ppcgeeks) is one of the few sites that will help the unfortunate owners of this fine device.
I was able to use a program called quick menu (found here, I think).
Then overide the start button to kill the native start menu.
This is about all one cando to gain about 45 mb of ram.
Now that L(low) G(grade) has been invaded by north korea or something, the "Updater" now borks my USB connections. You can't revert back to v5, so we are stuck with buggy v7 and data that keeps disconnesting.
Vomitrizen won't support this device even tho it's still sold on their site.
====================================================
UPDATE: Emergency Download Mode Code
Since the "New & Improved" crap for an update utillity forced itself upon my PC,
I'm sure that at least 50 of us have suffered through this.
I found this:
http://www.lg-phones.org/lg-fathom-v...comment-page-1
Mauricio on 9 July, 2011 at 8:56 pm # How to enter into LG Fathom VS750 Emergency Download Mode Steps:
1. Turn off the LG Fathom VS750
2. Press “5″
3. Press “Power button” while “pressing 5 ” keystrokes.
4. Check the front LED is green and the screen displays “Emergency download.”
You can now connect your phone using the USB cable and use fashing tools to fix your LG Fathom VS750.
Caution: Remember to backup your files before flashing. This will erase all of your personal data.
And guess what, this actually works...
Just try it and see. If you want to abort the download, just tap the reset button...
Who ever wrote that bit about "pull the battery, then press a few buttons---- HOLD IT RIGHT THERE ---
What is going to happen with battery out of the unit?
You could press the Davinci Code and nothing will happen without power...
Unless you posses the "Glowing One Perk".
Pluging the power cord into a unit without the battery only prompts you to "Insert a Battery".
So, MUCH THANKS to Mauricio.
I have been searching for this code for some time now, but for some reason it finally apeared.
Now if only some developers would find it in their hearts to help us root this baby, "Oh Happy DAY".
ENJOY..

If ya wanted a new look you could install Wisbar Advance Desktop or ThrottleLauncher, both fully customizable and a lot nicer looking that SPB Mobile Shell IMO.

Can you give more informatiom?
Is your phone GSM or CDMA?
What ROM are you using?
Have you added any other apps?

Hi! It is important if you can tell us if this is a newer problem or if this had always been the case with your device. Also, if this always happened to your knowledge, can you tell us when you had acquired the device?
Here are a few suggestions:
1) If you can back up all your files/contacts/etc. and try to flash the stock ROM, assuming you are using the original ROM. It could be possible that software could be affecting it. This would be best to wipe evrything away and begin with a cleaner slate.
2) How about, if you can do this on your own, try to install HardSPL, and flashing it to a customized ROM. Chances are if there is a bug in the stock software it could be coming from the stock ROM that is being used (if the first way does not work for you).
3) could it be a virus? I would suggest to install an anti-virus program (I use Lookout Mobile for Windows Mobile - its free and has a pretty good security suite). I can't say how effective its anti-virus program is but it has been pretty good for me. Even install one that is only a trial (ESET for Mobile, Kaspersky for Mobile, etc.) and have it scan your device. If anyone know how good Lookout Mobile is please let me know!
4) Could it be a radio firmware issue? I am not too familiar with this I would hope someone can answer this and maybe they can help you get the proper radio verison and flash it (I believe that you would need to unlock the BIOS - HardSPL basically - to ensure safe flashing of the radio firmware).
5) If the software is not a problem, chances are it could be a hardware issue, as in maybe the GSM chip is bad. I would be more inclined that it is a software problem rather than hardware but you can not rule out hardware.
This is assuming that you are using the GSM version (not CDMA version as I believe there is a separate forum for that).
I hope i am able to help you! Yes I agree with johnjctt1 - It could be an application you have installed that would be simple enough to rememdy, maybe try uninstalling each app, beginning with the newest one you had installed, and try data/voice simultaneously to see if an app was causing the reboot of the device.
Good luck and let us know the progress! This is the best advice I can give you without knowing a little more about your device. johnjctt1 was correct in asking those set of questions. I love how we all can support one another!
