It is possible....

Yes it is possible, in fact I tested a new kernel (zImage) last night that makes 384 MB available (compared to 256 MB right now). It boots unbelievably quick (like less than 15 seconds!) and the phone runs much smoother, really amazingly quick. When I boot up Android with only 256 MB of RAM allocated to it, I have a maximum of 120 MB free (usually less like 115, 110 or less).

With 384 MB allocated i had about 250 MB free, much better. Last night's kernel had some issues left (wifi not working, issues waking up).

Apparently it's been fixed already so we should have a new kernel available today.

Cotulla on his end is working on getting the 512 MB kernel working and he's close apparently. I think the remaining memory (the remaining 64 MB) will be used for the system or for the 3D buffer..... Not sure though...

Also your current Android build will work fine, all you'll have to do is replace the zImage and edit the startup.txt (to change the memory allocation values) and that's it. It might get a little bit more complex (like maybe replacing the wifi module) but all in all with proper instructions you should be able to do it in a few minutes.

Well let's wait and see... But 384 MB available already makes a huge difference so that's great news...

Hope this helps....

PS: I am amazed at the number of useless posts in response to your question.....

Is their an HD2 forum or Community page or maybe even an IRC room with a more knowledgeable or atleast selective userbase? The devs are incredibly intelligent, but the amount of know nothings makes filtering out the noise headache inducing. Seems XDA is getting too big for its own good.

Weird, using the fullram zImage, when i type sms, the screen flickers... where the image is a bit blurrish for a split second, then normal... But this problem kept repeating... i wonder what causes this problem?
[HD2 Android Q&A, Help & Troubleshooting and Genera] reocej:
Guys, anyway to combine this with the overclocking image in the other thread? This would be awesome. The other image allows you to overclock to 1113 mhz and adds the conservative profile in setcpu,(which should give better battery life) but doesn't give you any extra ram. This is getting betterer and betterer!!!
[HD2 Android Q&A, Help & Troubleshooting and Genera] jeckyll:
Bakedbread,

Try again after a fresh reboot.

su

mount -o remount,rw /system

-o (it's the letter o, not zero).

Make sure you receive no errors for the "mount" line, and then the command: chmod 777 /system/lib/modules/bcm4329.ko .
[HD2 Android Q&A, Help & Troubleshooting and Genera] kayslay21:
alright, i tried this again and now its working better, besides the gliches in the screen it is superfast, my quadrant score was 1566! idk if im using all the ram still tho bcuz with the last zImage that was 384mb, i would have around 250mb to 260mb free without running anything and with this fullram zImage i usually have about 290mb free, wouldnt it be way more if i was using all the ram???
[HD2 Android Q&A, Help & Troubleshooting and Genera] Bakedbread:
thanks for your quick help

but everytime i type the mount line, the terminal outputs

""Usage mount [-r] [-w] [-o options] [-t type] device directory"

i tried on a fresh reboot as well but still get that

and once i do the chmod777 line, nothing outputs and i try Wifi but am still getting an error :(

i might just buy the SU explorer if its easier..

or can you tell me the command lines for the terminal to manually push the bcm file to the /system/lib/modules folder?

i have super limited experience with linux, so im not sure waht they syntax is
[HD2 Android Q&A, Help & Troubleshooting and Genera] tinuz97:
Just installed the new fullram zImage....jezus! faaaassssstttt,but indeed also graphical issue here with the lines,hopefully it got fixed :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] Bakedbread:
hey jeckyll,

just as an update, i bought SU explorer and just did it through there.

i think there was a problem with me copying the bcm file throuhg Linda Manager to the /system/lib/modules because i noticed the file size was 0.00 kb

But using SU explorer i could make the system read/write, copy the file and change the chmod settings fine and now i have wifi working! :D

thanks for your help though!

heywhat am i doing something wrong here? i downloaded the fullramnopc and renamed it to zimage and copy pasted the default.txt to my startup and it isn't loading at all. could someone help me out plz would love to test out and give feedback!
[HD2 Android Q&A, Help & Troubleshooting and Genera] brolee93:
how many ram after instal zimagefullnopc ? i have on quadrant 393064KB its normal ?
[HD2 Android Q&A, Help & Troubleshooting and Genera] ubaidkhaliq:
i am also getting about 380mb ram with full version zimage ;(

same with the 386 version.

does that mean 576 mb ram is not enabled ;?
[HD2 Android Q&A, Help & Troubleshooting and Genera] RaiderX303:
576mb ram is enabled, the full ram version enables all the graphics ram, radio ram and all available program ram, ht will only show ~400mb due to the rest of the ram being taken for other things, just as in winmo you only get 448mb ram when the full 576mb is unlocked and only 333mb when it isnt unlocked
[HD2 Android Q&A, Help & Troubleshooting and Genera] ubaidkhaliq:
thanks for the explanation RaiderX303 ;)

the confusing thing is that with 386mb zimage it shows 371 mb total 224 mb free

and with full ram zimage it shows 383 mb total and 255 mb free

dont u think the difference is too small ;? when i jump from 386 to full ram zimage ;)
[HD2 Android Q&A, Help & Troubleshooting and Genera] BearsLikeHats:
I think the default.txt should be renamed to startup.txt
[HD2 Android Q&A, Help & Troubleshooting and Genera] mackman3:
Has the zimage been updated to fix the graphical issues yet?
[HD2 Android Q&A, Help & Troubleshooting and Genera] RaiderX303:
not yet, although ive managed to reduce the number of glitches by using the desire libegl files, looks like the drivers have been changed from the nexus drivers to the desire or evo drivers

Kool I'm going to try that then. What android build are you running Raider? And I'm running MattC's build where did you get those files from?
[HD2 Android Q&A, Help & Troubleshooting and Genera] benmeilink:
Only 145 MB internal storage?

Hi guys,

I have only 145 MB internal storage... and thats not a lot. So I want to increase that, but with wich zimage? I'm using a darkstone v1 build..

So if anyone can recommend a zimage? Please! (With startup.txt)

Thanks!
[HD2 Android Q&A, Help & Troubleshooting and Genera] jdm_cars:
lol, I guess I was the one who didn't read the whole thread.
[HD2 Android Q&A, Help & Troubleshooting and Genera] sopL87:
jdm_cars, you probably should read carefully. benmeilink wants to increase internal memory, he has standard darkstone v1 with only 256MB data.img, and he is misleading internal memory with RAM, about wich is conversation here, in this thread. For increase of internal memory go here.

RaiderX303, are you replaced files from "egl" folder, from any of previous builds? Wich one?
[HD2 Android Q&A, Help & Troubleshooting and Genera] mackman3:
I would like to know this as well, the MattC Leo build doesn't even have a EGL folder inside it
[HD2 Android Q&A, Help & Troubleshooting and Genera] sopL87:
then check again: system/lib/egl/.
[HD2 Android Q&A, Help & Troubleshooting and Genera] jdm_cars:
thanks for the clarification, lol, I guess I never installed that many apps so never thought about tweaking it, althought I can't get enough of more ram, lol.
[HD2 Android Q&A, Help & Troubleshooting and Genera] mackman3:
We're talking about on the sd card right because I'm not finding a system folder on there. I looked several times. I've found a desire build with these files but where do I put them on my sd card im guessing in the root?
[HD2 Android Q&A, Help & Troubleshooting and Genera] kayslay21:
yea RaiderX303, can you post those files needed to take away some the glitches in the kernel
[HD2 Android Q&A, Help & Troubleshooting and Genera] foxcheng:
OMG, with the latest full ram zimage nopc, my HD2 fly :D

No sod, no lag touchscreen, can use wifi, boot very fast, the neocore test become 28.4fps from 27.6(slightly improvement XD), wanna try asphalt5 and nova later :)

just a minor flaw, when i click and hold, the place i touching gain some busy black lines, not an annoying thing for me ;)

using froyostone v1 non-sense, just edit the startup.txt for 2 lines.

set mtype 2524

set ramaddr 0x12800000

set ramsize 0x1d300000

set initrd_offset 0x00a00000

set KERNEL zImage

set initrd initrd.gz

set cmdline ""

boot
[HD2 Android Q&A, Help & Troubleshooting and Genera] ubaidkhaliq:
just wonder if any body has noticed that there are two settings for fullram zimage

set ramaddr 0x12800000

set ramsize 0x1d300000

set ramaddr 0x12800000

set ramsize 0x17c00000

i have tried both, the 2nd one shows extra ram when used with dan1 froyo,

but does not make any difference with darkstone froyostone build.
[HD2 Android Q&A, Help & Troubleshooting and Genera] mackman3:
Are you still seeing graphical issues in one or the other?
[HD2 Android Q&A, Help & Troubleshooting and Genera] ubaidkhaliq:
yes, with both settings the there are lines on any thing that animates
[HD2 Android Q&A, Help & Troubleshooting and Genera] mackman3:
I figured as much, I tried getting ahold of raider since he said he replaced the elg folder with original stock desire files within the system.ext2 file. And saw some results but I cant figure out a program that'll let me explre AND edit the ext2 file
[HD2 Android Q&A, Help & Troubleshooting and Genera] toxtrepla:
You will need to mount the ext2 file in any Linux distribution as root. This will allow you to modify whatever you need to.

In Ubuntu for example... mount -o loop /directory/system.ext2 /directory/folder

This of course being done through the terminal and replacing "directory" with the actual path to the file. This will mount the ext2 file to the folder you chose. Edit what you want, and then unmount to save the changes. Pretty simple..

[HD2 Android Q&A, Help & Troubleshooting and Genera] simax:
guys lets clarify this...

they said only nand could make it happen, but still only 412mb ram. why?
[HD2 Android Q&A, Help & Troubleshooting and Genera] zarathustrax:
I think we've been using full RAM for a while, even with SD cards. There's no reason that nand would allow this while SD wouldn't. I'm pretty sure that a certain amount is used by system and video that isn't user accessible.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Alganon:
does anyone know for certain by now?
[HD2 Android Q&A, Help & Troubleshooting and Genera] raven_raven:
I think we're already using full RAM. HD2 normally utilizes 448 mb of RAM. But when I type "free" in terminal emulator in few ROMs I see around 410 mb of total RAM. I remember from my G1 that about 100 mb of RAM were taken by radio + GPU and NOT reported by system, so it would be possible that we're using full 576 mb of RAM while system reports around 410 free (because rest is used by radio and GPU). I don't know if I'm right though.

I've been testing the 384 MB kernel (zImage) from manusfreedom and the phone runs great. Everything works, wifi, 3g and it's much more responsive than with the 256 MB kernel....

The phone has about 250 MB of free RAM which is much better than at most 120 with the 256 MB kernel...

Helps a lot when browsing the web and stuff...

I had to replace the wifi module (bcm4329.ko) in /system/lib/modules/
