[Windows Mobile Software Development] amirdt:
thanks,

seems that there is a problem with the file, you must save it with encoding UTF-8 otherwise the translation text inside will not be correct;

Once you open it with notepad, do "Save As" and look for the encoding combo box at the bottom of the dialog box...

This new main screen do not look good IMHO:

1) It's redraw very slowly. Now I can see how every buttons appear on screen.

2) Blue text on blue background - hard to read.

3) Background picture is obstruct.

Also here is updated and fixed Russian language.

Thanx.

thanks for the language file, it was updated.

As for the graphic issues, I'll address them in the next release

Hi there looking for a leo app that automatically goes onto speaker phone once you have called out name and maybe also for handfree answering if you follow me, is there such a thing? I,m not wanting a bluetooth headset so any apps would be nice.

Hey guys, ive been away from the forums for a few days and I just realised that HTC have realesed a new 1.66 europe rom.

I just wanted to ask you guys how this rom is and if it is worth the upgrade? Are there any fixes/changes that you guys have noticed with this new rom?
[HD2 General] jakem:
I haven't had too much time to play around with it but the few things I've noticed are:

- the locking issue with 1.48 seems to be resolved

- the touchscreen seems less responsive

- a really annoying startup song has been added to the boot sequence (from memory there's a fix for this in the longer upgrade thread).

I can't say whether it seems any better at this point but I don't think it's any worse :)

hi folks :)

i've been searching for a proper bg4all-app on this forum for a long time. and believe me, i tested all of them posted around here :)

there are some which mess up my homescreen (as descriped by many others), but otherwise work good. and there's one which doesn't mess up the homescreen, but changes nearly EVERY manila/sense background, e.g. selecting a contact when trying to call etc.

i mainly use dark backgrounds, and so dark fonts can't be seen in the contact list anymore...

so, is there an other possibility / app to get a background on all the sense tabs (only the tabs, not on the "sub screens" of manila too) ? :)

thanks a lot and have a nice day :D

oh, btw: i'm using german stock rom and manila 1921.
[HD2 Windows Mobile 6.5 Themes and Apps] de Wolfe:
Just teke the solution of dzekinz. It works without any problem. To get this background in a couple of more screens, go to "Pictures & Videos" in "Multimedia"-Folder and browse to the background of your choice. Then click it and set it as "background for today". Maybe this helps you...
[HD2 Windows Mobile 6.5 Themes and Apps] hebbe:
thanks for your answer :)

do you have a link to dzekinz background4alltab application? searching this forum and even searching with google just returns this thread :p
[HD2 Windows Mobile 6.5 Themes and Apps] de Wolfe:
Sorry, I mixed up some good modders... :D The one that I meant actually is grzegorz10 - you find his BG4All here.

which one did you download?

It means I can choose my own picture to be my background for all manila pages?

[HD2 Windows Mobile 6.5 ROM Development] zenkinz:
how is that possible? Once you have 2.02 spl (with hspl replaced), you can't flash cook rom anymore, can you?
[HD2 Windows Mobile 6.5 ROM Development] seatone:
C'mon guys are you joking now, don't you?

For flashing cooked roms you need HSPL or SSPL!

Let's suppose that you have HSPL on your device.

Flashing an original rom (e.g 2.02 or whatever) from your PC it does NOT change your HSPL.

HSPL can be reverted to the stoc spl only by flashing an original rom from your mSD card.

So what is this debate with flashing HSPL 2.02? There is (thanks to cotulla/bepe) only 1.42 (for the time beeing)...
[HD2 Windows Mobile 6.5 ROM Development] anja31:
Sorry guys,

this is rubbish - you do not need spl from 2.02!

i have over 500 downloads for my german "576MB ROM" in 24 hours and trust me - there is no spl needed for that

Peter Deijnum i send you the files - prepair kitchen the way i told you and you will be fine

[HD2 Windows Mobile 6.5 ROM Development] mr.vandalay:
yeah you don't need 2.0 spl...

i asked miri and bobsbbq...anyway miri said this:

"no need for spl 2.0 to have 576, just use oemxipkernel from 2.02, and the oemdrivers and oemdrivershigh from it - ddi.dll (should be from 1.66)"

bobsbbq said basicly the same thing

well if you do everything like this and flash the appropriate radio you'll have 576mb of ram.

Hey can someone help me out.. i am new to windows mobile and i have a Htc HD 2. Now how do i put this Rom onto my phone and how do i enable the extra RAM.. also do i have to download all 3 files from the main post ? .. sorry am a n00b in win mo :S..
[HD2 Windows Mobile 6.5 ROM Development] dickenz:
No...... It's a kitchen..... I have downloaded it is fine.

Firstly this isn't a ROM. It is a kitchen... The files in the first 3 post will not help you unless you know how to cook. (Which is taking SOME of the files in the first post and using them to create a ROM).

Judging by your post you do not know how to cook so I suggest installing one of the cooked ROMs with the extra RAM enabled from the ROM development thread after installing HSPL... Again everything you need is on the first page of the HD2 ROM Development section of these forums.

if you want to use the oemdrivers from 202 you need the spl as well.. sorry for those who deny it but it's true I've been playing with this for a while now..

As already need the nk from 202 and the radio to get the memory but that doesnt give you much speed boost compared to using the full driver pkg

there's new audio in the 202 oem drivers (which seem to need the full oemxip from 202 ) the 202 spl beats the one time boot.

My original post was because this thread title gives the impression that there's a full kitchen with the 202 oem.. if you cook those properly then you get a one time boot

I couldn't give a flyingduck about how many rom downloads someone has..
[HD2 Windows Mobile 6.5 ROM Development] freyberry:
What do you mean by that? I just took OEMDrivers, OEMDrivershigh and OEMXIPKernel from 2.02 and I got the 576MB RAM.
[HD2 Windows Mobile 6.5 ROM Development] the_scotsman:
So what exactly are you saying? I'm a little confused.....I don't think he intended this to be a full 2.02 kitchen? Just enough to get the extra RAM...unless I'm mistaken.

The ROM seems to work fine using the supplied 21869. Although I'm having problems with the 21890 build.

make sure you have fwupdate & sqm (or dummy version of it) enabled otherwise your device will hang after a initialisation.
[HD2 Windows Mobile 6.5 ROM Development] Peter Deijnum:

The external packages are from 1.66.405.2

Oem is 2.02.531 thats means all the drivers ! only ddi.dll is from 1.66.405.2

OEMXIPKernel is from 2.02.531
[HD2 Windows Mobile 6.5 ROM Development] zenkinz:
I don't think the TS meant this is a full 2.02 rom (if this is what you are assuming), but just probably the xip + oem drivers/apps from 2.02.

I actually believe that a different version of spl does make a difference to the performance, as I had experienced it in HD. However, I am curious to the difference in speed, because I've cooked my own rom with everything except spl, and it's pretty fast. Maybe I will do once and see how it looks like.

do you know which section of nb file is spl? I've dumped out the nbh, and there are a few unknown nb files.
[HD2 Windows Mobile 6.5 ROM Development] the_scotsman:
ARGH! That was it...I had fwupdate disabled!! :eek:

I forgot that I need a dummy one to replace it :o

Thanks you!

Now all I need to do is find the manila 1922 package (cough cough hint hint :o) And how to disable that annoying message about unknown publisher every time I install a cab.

OH and why does my "OS Version" still say 21869, when I'm using 21890? Is that the value I need to change in nk.exe?
