libs 1.8 are installed already.

you can edit gps.conf after install also.

but reboot after done.
[HD2 Android NAND Development] dorimanx:
that ok. if you use sdswap the ext swap is not needed.

ignore this error.

if you see swap OK then all good.

use

[HD2 Android NAND Development] Looki75:
After each new ROM flashed, you need to modify the gps.conf file OR flash the one you need from this thread: http://xdaforums.com/showthread.php?t=953630

The thread is a bit difficult to read, look for the line "XDA Members Click Here" it brings you to an ftp site where you can download the CWM flashable ZIP you need (for example on the ftp site, go in folder "eugps/EUGPS 1.2/" and download FRANCE.zip!!!

If the ROM you flash already has the GPS libs that you want, then it's not necessary to flash the GPS libs after you flashed the ROM :)
[HD2 Android NAND Development] Tiller:
To change the ntp servers in gps.conf, refers to:

http://www.pool.ntp.org/zone/@

And as Dorimanx said, you can do it after the installation, by editing /system/etc/gps.conf with an editor in root (Ie. Root Explorer)
[HD2 Android NAND Development] Gho57:
Thanks for this fast ROM! I think you have to add into you rom Fasterfix ( free on market) for changin gps zone "on fly" ;)

hi dorimanx

i have one little problem in call mode :

in call, when press speaker button, my phone speaker get low sound .(2.8.1 without kernel update no problem and sound high and no problem).

i tried 2.8.1 again without kernel update and no have this problem ..
[HD2 Android NAND Development] dublus:
Dorimanx - I have a special request.

The 2.8.1 ROM is great for me (using light right now) but it seems the power saving settings cause wifi to sleep until the screen is on even if the setting in advanced wifi options is to never sleep. If something is actively using the wifi connection it won't sleep but if nothing is using it, it will sleep until the screen is turned on. It's important for me that wifi stay on at all times because I am using t-mobile wifi calling at home and at work and when I leave one place and enter the other the wifi signal drops (along with the wifi calling, of course) but it never connects again until I turn the screen on. At that time, the wifi calling app also turns on because it just sits there waiting for an active wifi connection. Previously the ROM didn't behave this way. I don't expect you to change the ROM back just for me but can you tell me what to tweak so it works the way it use to?

Thanks.

Definitely look into this. It saved my phone. I bumped into a low counter top with my phone in my pocket and it made a dent in the exact place where the phone signal antenna connections are. There's two of them and it crushed one. When I took my phone apart and tried to fix it the little tab just broke. Luckily where I work we have these tiny little gold plated contact springs that are made for this exact purpose so I was able to solder one in place of the broken contact. Phone's been perfect ever since.

2.8.1, cron2.0,heiros v6,boostboot,voltage, all latest. Ever since 2.8.0 when I resume my phone from standby (at least 10 min or so in standby)i have no data connection and must tap air plane mode then tap again to get data back or tap 2g/3g.
[HD2 Android NAND Development] Traukoman:

[HD2 Android NAND Development] Hammerfest:
in reference to my earlier posts about the Swap Partition, it seems my SD card's partitioning was faulty... it was done right... and I did the script again on the card and it worked proper this time... I really dont know what the hell happened, seeing as I ran the same script to set it up before I jumped back in and again after... same thing... 2 different outcomes..

thats solved, but the issue I still have is that my charge light is green instead of orange...

Although sometimes video works normally?

I get a 'cannot connect to camera' error when it goes tits up.

+1 for data problem

Keeps jumping between 3G and H

I'll also be looking into the possible weak signal fix.
[HD2 Android NAND Development] dorimanx:
I see that new kernel has bug with video recording, I will check the logs and report to Dev and ask for fix.

for now or dont record, or reinstall 2.8.1 to get the old kernel, if you have the 2.7.4 v6, then just install it to fix the camera.
[HD2 Android NAND Development] dorimanx:
I will check what can be done about data, camera not working with new kernel, bug in development.
[HD2 Android NAND Development] MystaMagoo:
To be fair I've not used data plan before as I did not have one.

So I've nothing to compare with and cannot say it was even working ok in previous releases for me?

Also weather has been nasty here for a few days which can also affect data signal.

I may even have the poor antenna contact problem for all I know?

I do know I have similar problem as above and I have to reboot to get data back,airplane mode on then off sometimes works but not always.
[HD2 Android NAND Development] MystaMagoo:
Anything I can do different?
[HD2 Android NAND Development] Visentinel:
I recently studied weather effects on cell phone signal. I can advise without a doubt that the weather does not affect signal. :)
[HD2 Android NAND Development] ORiZorrie:
Weather does affect signal strength. Electromagnetic waves (RF type) travel better in dry air than in humid conditions. If the medium changes it affects the distance the signal can travel. And in higher frequencies the attenuation effect is stronger than in lower ones. In lab environments this effect can be measured if you work under constant conditions (which is very hard since interference really is a ***** ;)).

However, the weather change must be quite severe before you notice this effect. So generally you will never notice this effect as there are usually multiple towers in your cell phone range.

So basically it could be your problem, but it's very unlikely.
[HD2 Android NAND Development] Visentinel:
In my recent study I learnt that it would take a cubic meter of solid ice to have even a -1 dbm effect on cell phone signals. so unless you where trying to make a call from under the arctic you won't see any effect on your phone signal from any kind of weather conditions.

I will however concede that windy conditions have effected my mother due to the fact she lives 50km from the cell tower and most of it is through bushland, the wind causes the trees to move about allot which I suspect is the reason she can barely use her 3 g internet during windy days.
[HD2 Android NAND Development] Visentinel:
Don't bet on it, I tried almost aggressively getting support on making an sd build and I got a response tantamount to "completely ignored"

Dorimanx said in one post he was going to release one after he made a new version, that was 2 versions ago now.

I have 6 bad sectors now, I guess when my hd2 starts having issues with this ill get new phone instead bother with sd builds, is to hard to get help with it.

Kernal devs also ignored me when I ask both Jan willum and Heiros about getting a Kernal build set to nand-boot 1 so it could be launched from magldr instead of Haret.

Its futile :@

Any idea?

Some apps not belong to system. they are not SYSTEM APP

so just install them on sdcard.

for them to work as system app they need to be recompiled and recompressed.

Hello

Pehaps you got no answer because no one here is able to help you. I imagine that you have already search elsewhere to find how make SD ROM, and you found nothing nowhere to explain how to do? (I don't search by myself and as I'm not interesting in such a thing, I won't) Meanwhile, I think that informations are somewhere in the net and it must be possible to find them no?

Besides that, If you wait for Dorimanx to help, I think it will be a lost of time because he is so bovered about making is rom better and better that he must have no time for that.

And, also, perhaps it is not possible to adapt a nand rom to SD because to much things are different.

And if you have bad sector, you will have also under WinMo so same problem but on other OS.

It's strange to see that nowhere we can find a soft to fix that dam bad sector.
[HD2 Android NAND Development] dorimanx:
I am sorry that i cant help you.

I have no idea how to build an SD build.

and lots of my tweaks and configs will not work there so, it's a waist of time.

it's will be just one more "sucks" rom.

so nand only here.

I am close to find a way to create EXT4 partitions for SYSTEM , DATA , CACHE!

then the I/O boost will be X4! if we see max 1450 at I/O score in quadrant, it's can be 4600!!! and it's unbelievable global speed!!!

And best part that i will be able to scan and fix bad sectors on EXT4 partitions before booting!

But it's all still in progress... will take time to create all.

hope now you understand why i don't go back!!! there is no way back! :)

[HD2 Android NAND Development] Hammerfest:
.... such a tease with your Ext4 partitioning scheme...

:P the wait is KILLER... I am having SO MUCH fun with my HD2...

now I gotta figure out how to kill off the two boot screens... just like WinMo and WinPhone those few seconds can be shaved off boot by killing off processor sucking startup animations... after that im going to remove all the default sounds/pictures and such to shrink the size of the rom... possibly 140 even!

also cannot wait to see if OP uses those 2 tweaks posts and finds even more goodies to help speedup/improve this beast of a device!!!

Incall volume issue

I can see that the low MIC issue has been fixed with new micgain values for the new kernel (though mic control already did that job for me) , but has the incall volume adjuster? Are you able to change the incall volume during a call without removing the device from your ear :confused:
[HD2 Android NAND Development] Visentinel:
OK I totally trust in you, you know that :) I have had faith that you would find a way to extend the life of this phone,it was just that faith was getting weak because everywhere I turned for information or help for sd build I hit a wall. If you can make this global ext 4 then do it, it's better than sd build, I know this.

I can't wait :D

[HD2 Android NAND Development] Visentinel:
I have been having problems with huge amounts of garbage memory, this afternoon I actually ran out of swap and had to reboot coz my phone was so slow.

After reboot the same apps running and under 10mb swap use.

I did some research into how android memory management works.

What i learnt is the Dalvik VM cache size is the max amount of memory a single Dalvik virtual machine can grow to before it does garbage collection.

So what I think is happening is system processes eventually fill up with garbage memory and if we multiply say 30*64 we get 1920mb

So if only 30 processes( virtual machines) hit the max that's almost 2gb of Ram requested.

Now I can see the problem in that.....

I have reduced my Dalvik VM to 16mb, the Rom is not slower for Now, but I will see how bad having garbage collection occur affects performance, 16 is not permanent,i just want to see how much performance hit there is by having GC occur.
[HD2 Android NAND Development] Visentinel:
Here is the information i learnt about Dalvik virtual machine. By the way my phone feels faster for Now with 16m Dalvik heap size.

What will be interesting is overt time as garbage memory begins to build up and the garbage collection routines kick in.

This setting should have little effect on overall system performance. The only scenario where it would be beneficial to increase the maximum heap size would be if you have an application that is very close to using up all of its available heap space, which would force it to run garbage collection frequently, which would use up CPU cycles. It is possible that lowering the maximum heap size could be beneficial in that it might prevent an application from obtaining more memory than it needs (by forcing it to garbage collect sooner), but that all depends on how the Dalvik VM is implemented

VM is Virtual Machine, as in JVM. Dalvik is a Android's virtual machine. Java code is compiled into bytecode which is executed on a virtual machine, it's slower than compiling into native code but means you don't have to install a different version of the compiled code for each different hardware or o/s implementation, you install a o/s-specific VM that has native routines called from the generic bytecode. Theoretically, subsequent releases of Android could/should get faster as more native code is included in the JVM.
[HD2 Android NAND Development] Hammerfest:
so I gotta ask what WiFi tweaks are being done...

I can care less about power... but im literally 15~ft away from my accesspoint and get **** for WiFi reception on my HD2... on my HeroC, Mogul, Laptop and desktop they are 90%+~... on the HD2... its Red/Orange/Disconnecting alot...

+Performance for WiFi

-Power...

willing to make the trade if its just some setting I can manually adjust... this is just insanity...
[HD2 Android NAND Development] D3LTA:
+1 same here
[HD2 Android NAND Development] Visentinel:
Update, this is now a project to find the balance between enough space for the system process and keeping garbage to a minimum.

16mb lead to a hot reboot, so it needs enough space to allow system to grow legitimately.
[HD2 Android NAND Development] feanor91:
+1 yes, apparently I have some problem to download from wifi
[HD2 Android NAND Development] guinhill:
That is verry cool.

It will mean a clean data partition before one can use ext4 there. that will be fun with backups again.

I found this, with no ammount of googling : "android CWM format system Ext4"

http://xdaforums.com/showthread.php?t=868720

But after a try, it won't format our partitions.

So things really are not as simple as adding a command like
