Hi all,

I replaced Kernel with Rafpigna 1.9 GB one (see here http://xdaforums.com/showthread.php?t=940823). and now bluetooth seem to work well. Pairing and file transfer from another phone was painless at all.

I had the phone running this way for a full day, the only problem I noticed is that I can't play divx files anymore (only audio, maybe someone could help....). I got also an improvement in battery life, that was not very good for me before, since I noticed that this kernel works well with the radio I use (2.12....).

To install the kernel is quite easy. Make a backup copy of your SD card, then just download the 1.9 GB version and follow instructions.

Hope this can be of help......

EDIT Divx playback works. I got problems with Moboplayer, I just changed player and now it's fine.

Can you provide the full method... because in the mentioned link, it is written that install this using clockwork mod recovery.. there is no method for sd builds... TIA
[HD2 Android SD Development] dody:
any one knows the compatible arabic files please ?

and customizable themes.. i can use to change the dock bar ? (app lancher, apps add replace phone icon, etc
[HD2 Android SD Development] nicola ricci:
Yes, I will be more specific.

I tried this in an SD installation starting from WinMo (Haret). To have it working these are the steps I followed:

0) make a backup copy of sd card

1) format sd card and prepare it for a fresh install, just keeping previous data.img to avoid to restore everything

2) download and unzip the file "kernel_rafpigna_1r9_OC_GB"

3) extract file zimage from "boot" folder and copy it in android folder in sd card, replacing the existing one

4) In android folder create a new folder named "root" where you will copy "system" folder with all its content

5) reinstall the build

It should work as well if you just replace zimage and copy system folder on an old installation, rebooting at the end. I actually didn't try it.

I had this very nice build running with Rafpigna kernel for 2 days now and for me it's superfast and stable like before, but BT gives no troubles and battery life is at least 20% more than before in normal usage.:D

Just one warning: the network setting "WCDMA preferred" is not working at all for me (I use RMNET). I set "GSM auto (PRL)" and everything runs perfectly.

Thanks to Tytung and HaPeWe for this fantastic build.:)
[HD2 Android SD Development] dody:
when i connect to my laptop and open sd card to copy some apk to download and delete some of the files on sd card ... i dont see any changes !!!! and the files i deleted still there ,,, some times after a few reset i find the copied and the deleted on the sd but the copied is 0.kb
[HD2 Android SD Development] walidhazem:
same here but what I do is that I copy them from USB and if they r not there then I turn off phone and take out sd and put it in the computer and check if the files I just copied are there and not 0kb if they r not 0 then boot and check, but if they r zero then delete the files and copy them again and take out sd and put it back in and check again then boot and tell me what happens :) hope this helps
[HD2 Android SD Development] david-olivier:

SD not mounted and some other issues

Hi Folks,

Have isntalled this awesome ROM, but I'm facing some issues, namely:

- When I try to install an APK from GMAIL I get the following error:

"Th attachment could not be downloaded because the SD card is missing or not mounted.";

- When I try to install an APK sent to my hotmail account I get a different error:

"Parse error: There is a problem parsing the package.", by the way this same APK installed correctly on my previous Android ROM;

- When I connect my HD2 to my laptop it doesn't ask me which kind of relation I want to establish between my HD2 and my laptop. Basically the only thing I get is my device to charge.

All the help will be highly appreciated! Thanks.

Cheers

can display be changed to a higher resolution?smaller icon,like the americanandroid build,

btw m LOVING your build,its light,its smooth and fast. i just miss the higher resolution

thanks for the great build and all your hard work
[HD2 Android SD Development] Patrick P931:
Have you tried editing the startup.txt?

From the original rom:

set cmdline "rel_path=Android nand_boot=0"

A really good guide of what one can edit in the file (taken from another rom):

### Leave cmdline as default if you don't know what you are doing ###

# default: set cmdline "rel_path=HD2ONE"

# sample: set cmdline "rel_path=HD2ONE data_size=512 lcd_density=200 gps_zone=us ram_system=1"

### Meaning of Variable ###

# rel_path: folder name of the build

# data_size: size of data.img, 1024 means 1024MB

# lcd_density: default value for android is 240

# gps_zone: country code, us, fr, jp, etc.

# ram_system: set this value to 1 to enable system in ram feature

### Leave cmdline as default if you don't know what you are doing ###

In your case I would try:

set cmdline "rel_path=Android lcd_density=167 nand_boot=0"

I believe that 167 is the resolution used by ACA.

Just remember to save the original file as backup, because I have no idea if this will work. ;)
[HD2 Android SD Development] Patrick P931:
Ok, I did this.

Tested in my car and it seems to work as it both paired and connected. Will try making calls later on tonight.

Thank you.

Cheers,

Patrick

edit: may have the same screen prox sensor fault as noted before, takes about 3-5 seconds after moving from sensor that the screen wakes up. Will try a new install and see if that helps.

edit no 2: fresh install and the prox sensor is back to what it should be. :)
[HD2 Android SD Development] Patrick P931:
Ok, tried using it now and BT does indeed work. It paired and connected to the BT handsfree in my car, sound is good, all is well.

But, the phone feels slower!

Everthing from scrolling to opening a program or using a file explorer feels just a tiny bit slower.

Now I will charge it overnight and we'll see how well it copes tomorrow. ;-)
[HD2 Android SD Development] razer4ever:
well..mine works quite well..few glitches with go launcher ex with live wallpapers but really fast in other words..even contractkiller works pretty good...i've switched to raf 1.9 oc 2 hours ago and the bt and wifi is working very good..i'l post some updates after 3 or 4 days...

to be on subject.. i guess everyone should try it as everyone is using the phone differently...
[HD2 Android SD Development] Patrick P931:
Raf 1.9 made my BT function well but it also made my phone a little bit slower and, most alarming, it made it consume more battery.

I did a "full cycle" recharge during the night, let's see if that results in a bit more stamina for today.

As I am 99.9% on Android perhaps it is time for a nand-rom?
[HD2 Android SD Development] nicola ricci:
It seems that battery drain is related to kernel AND radio. raf's kernel is more battery efficient with 2.12.50..... radio, tytung's one maybe is more efficient with 2.15.50.....

My experience (I use radio 2.12.50........) is that shifting from tytung to raf battery life improved around 20%.

[HD2 Android SD Development] idlehands:
When i launch some apps it appears a message that says theres an error with the process and i have to uninstall it then re download it from the market and thats not normal any advice? Also there are times when suddenly the device starts loading the nexus logo and do nothing else... advices thanks!!
[HD2 Android SD Development] EngineerMind:
The problem is that Rafpigna build is kinda old (pre-May), so it doesn't have the bluetooth low-standby-power fix in it. So if you use bluetooth with the above kernel, the standyby current will be about 65ma - no good.

Tytung's builds (since May of 2011) have the Bluetooth low-standby power fix in them - so standby with bluetooth shoudl be 3-10ma.

So we need to figure out how to get the bluetooth fixed using the tytung build of the SD port if you want low standby current with bluetooth on.
[HD2 Android SD Development] EngineerMind:
OK,

Bluetooth seems to work fine in Tytung's NAND build:

http://xdaforums.com/showthread.php?t=905060

But, I am having the following issue with the bluetooth of this SD port of it:

When my BT device is in pair mode, "Scanning for devices" on the HD2 seems to not find anything. However, if I turn "Discoverable" checkbox on and then off, it seems to help the pairing "along". When I mean "along" is that the first time I toggle the "Discoverable" feature on, then off, it will "find" my BT device, but when I click on the device the pair process seems to "hang" until I again toggle the discoverable checkbox on, then off, then the pairing will complete.

Then when I reboot, it wont pair with my BT device automatically. It seems I again have to "help" it along with the connection by manually toggling the "discoverable" feature a few times. Very strange.

UPDATE: It seems that the cycle of turning "Discoverable" from "OFF" to "ON" is what "pushes" the pairing along (and not from ON to OFF) if this helps at all.

So, HaPeWe - is there another change that needs to be done to Tytung's NAND build to get bluetooth working in this SD port?
[HD2 Android SD Development] HaPeWe:
Let's hope and see. 2.8 SD-Port will be available soon - I think in 1-3 days.
[HD2 Android SD Development] EngineerMind:
Sorry, I didn't explain myself correctly...

What I meant was:

When you said "SD-relevant Adjustments" in your first post, the impression I get is that certain things need to be "adjusted" to convert a NAND build into an SD build. And since bluetooth works perfect in the original 2.7 tytung NAND build, it seems something "Broke" during the convertion to your 2.7 SD build.

So, I was just wondering if there was an additional "adjustment" that needed to be added to the conversion so bluetooth won't break?
[HD2 Android SD Development] trex3300:
Looking forward to that, you are the man. I also looking for a way to make wifi calling by tytung works on the sd build, any tips?

http://xdaforums.com/showthread.php?t=1038784
[HD2 Android SD Development] HaPeWe:
The adjustments are only boot- and path relevant, with the same radio-ROM the SD-Build should work identical with the cLK-Version.
[HD2 Android SD Development] EngineerMind:
Now I am curious!

When Tytung said "V1.8 is the final SD version" in this thread from Dec:

http://xdaforums.com/showthread.php?t=793924

It gave me the impression that creating an SD version of his NAND rom was kinda time consuming to do everytime he produced a new NAND build and thats why he stopped releasing SD versions of his builds.

But, since Tytung just released 2.8, can you detail exactly what you do to convert his NAND build to an SD build?

P.S. How can I send you a small donation for your time with this?
[HD2 Android SD Development] HaPeWe:
Look here:

http://xdaforums.com/showpost.php?p=13809122&postcount=29

Because of my own CM7 based build (using tytungs kernel) most of the work is allready done, porting tytungs cLK-Version to SD takes (with testing and uploading) only a couple hours.

- create a virtual filesystem (system.ext2)

- copy the cLK-Build into it

- set permissions and system links

- sometimes a few changes in rootfs

- bundle sd-system-files

- testing

- uploading

- posting

to tytung, because he creates great builds and solutions for many hd2 related problems.

P.S. V2.8 is available
[HD2 Android SD Development] EngineerMind:
Thanks for the detailed info - even though I am a WM developer, I can see it's still pretty involved.

Downloading 2.8 now.....fingers crossed that bluetooth will work...
[HD2 Android SD Development] EngineerMind:
Crap - Bluetooth still no good....I have to tap the "discoverable" a few times to get it to pair fully. Then it wont auto-connect after a reboot without another tap on "discoverable".

Getting bluetooth to work on this SD build is pretty important to me, and I would be happy to "donate" to anyone who can getit working.

-John
[HD2 Android SD Development] HaPeWe:
Take a look at post #85 ff, maybe you can use that work around.
[HD2 Android SD Development] EngineerMind:
Thanks for the post - but that kernel was a "Pre-May" version, so it doesn't have the bluetooth low-standby current fix thats in Tytungs kernels since May, yeah bluetooth does work, but draws 65ma in standby when BT is on - which puts me right back in the same situation I am currently in with Darkstones SuperRAM froyo :(
[HD2 Android SD Development] lomo2002:
hi guys,

This rom very simple, quick and stable and i am loving it. The only problem that i have, is i do not know, how to show my contacts from SIM-card without importing it. any solution for this?:D
[HD2 Android SD Development] gpat1:
Hello

Is it possible to use the data.img V2.7 on V2.8 so as not to reinstall all.

I like the v2.7 if it is stable but just one problem with the bluetooth control buttons

best regard
[HD2 Android SD Development] yugoport:
You can use a fantastic tool available here in SD development, its called portadroid, you can port the rom directly yourself, I did it and have Bluetooth working very well, but for some reason even using the same kernel, it feels a bit slower, or its just my imaginatiob, but I'm waiting for some comments.. try it and give your feedback..
[HD2 Android SD Development] HaPeWe:
Yes, 2.7 data.img works with 2.8.
[HD2 Android SD Development] cariocap:
Why don't you simply turn off BT when you're not using it ?

I always do this with BT, Wifi and GPS when they're not in use.

Just a few clicks
[HD2 Android SD Development] EngineerMind:
Believe me, I tried it, but could not get any ROM to work - even the ones the developer tested as being compatible - my HD2 will just hang on the second boot, and many other users are reporting the same problem.

I am a developer so I kinda know what I am doing, and I even tried the panasonic formatter, power on during boot, everything suggested, but still NG - I am confused why I can't get it working on either of my HD2's, but yet others seem to have not problems at all
[HD2 Android SD Development] EngineerMind:
I need BT to be on all the time because I use it alot - I would rather not have to keep remembering to turn it on and off to save battery power. Right now I am using darkstones SuperRAM froyo 1.5 and it works 100%, but has the 65ma when BT is in standby. So, I just need an SD version of android that has the BT drain fix in it.
[HD2 Android SD Development] trex3300:
Lets hope that Tytung have time over the weekend as promised to spin out a clean SD built with a working bluetooth. Iam kind of hoping that tytung will also have enough time to release a wificalling apk file that can be install on an SD build as well.

SD-port of the -MAGLDR Build:

Hey HaPeWe,

Could you please port the MAGLDR Build, maybe that will solve the bluetooth issue.

Thanks for all your efforts.
[HD2 Android SD Development] silverwind:
I think it failed to install

You need to retry.

Format your sd card or use a new one (maybe there is damage in your sd)

or try redownload the ROM

Goodluck
[HD2 Android SD Development] HaPeWe:
I don't think so, that would probably only add an Internet issue (ppp/rmnet).

It appears that every build with a kernel that supports BT low power has this issues. It seems the problem is releated to the BT low power mode in combination with several BT devices.
[HD2 Android SD Development] Visentinel:
guys... this latest version boots from the AD SD option fine, but after the kernal finishes loading its booting my MIUI rom from NAND .. LOL !? WTF

im even selecting AD SD manually now and its doing it.

the magldr console clearly shows it booting kernal from the sd card... but then its resulting in a nand boot.

please fix
[HD2 Android SD Development] tamnteh:
i love this rom and it loading less than 3 minutes at first time... fantastic
[HD2 Android SD Development] LeeFred:
This version is very nice...

The reaction of every function is very FAST !!!

The standby current is about 10 ma, work perfectly.
[HD2 Android SD Development] Patrick P931:
Thank you for letting us enjoy this rom!

I have tried so many different roms - I have 6 of them on my SD card that I can choose when I boot but I always come back to this one although not having BT is making life tough at times. But the advantages outweigh that by far.

I use the stock version, the change of kernel did not turn out so well for me.

Looking at the original thread we see this:

I guess that the same updates apply to us?

Especially looking forward to see if the gps gets a quicker fix, it can be slow at times but once it locks it works flawless. Also a little interesting to see what will happen to my Google Maps as I am running 5.6.2. ;)

Downloading now.

Cheers,

Patrick
[HD2 Android SD Development] tytung:
Well, I looked into HaPeWe's rootfs.img which has the improper settings for low power Bluetooth, and has the wrong BT address.

Besides, CPU scaling governor is changed to ondemand when using his rootfs.img.

The default CPU scaling governor of the r10 kernel is interactive which is better.

After using my modified rootfs.img with my init.rc and init.htcleo.rc, Bluetooth works well for me.

Bluetooth will auto reconnect after reboot.

You can try my "official" SD version.

"The version is almost unmodified"

i think this is the secret of this rom. a few tweaks only.

really stable build, everything working, no bloat, nice!

ive added adw and a few apps and its great.

thanks guys
[HD2 Android SD Development] HaPeWe:
Thank you for the solution of this problem.

P.S. Can you take a look at my new rootfs.img (1. post) because I couldn't use yours for this build because I had SU issues with it.
[HD2 Android SD Development] toma62:
[QUOTE = tytung; 15290483] Beh, ho guardato in rootfs.img HaPeWe, che ha le impostazioni improprio per il Bluetooth a basso consumo, e ha l'indirizzo sbagliato BT.

Inoltre, governatore scaling della CPU è cambiata in ondemand [/ I] quando si utilizza il suo rootfs.img.

La CPU governatore scala predefinita del kernel r10 è interattiva [/ I] che è meglio.

Dopo aver usato il mio rootfs.img modificato con il mio init.rc e init.htcleo.rc, Bluetooth funziona bene per me.

Bluetooth riconnessione automatica dopo il riavvio.

Question about theme

Hi there, just downloaded this rom and am trying it and must say looks very smooth and good. Now forgive me but i prefer the sense theme, is there anyway to make this look like sense using launcherpro plus and what files and directions would i need? managed to get dock bar on screen but had original rom dock bar overlaid.

any help would be great

You're correct. I was using my "almost dead" Windows 7 partition (because of the Panasonic SD formatter) that has winrar 3.91.

Hi tytung

I could't find official tread for your SD version so i will quote here...

First your build is fantastic ,everything works fine.I use to use ACA builds since February and few days ago decided to try yours , i'm completely impressed, but i'm meeting one issue, on incoming call phone freezes and in earpiece i can only hear buzzer sound plus i have to wait few minutes untill it gives me unexpected error sign and few options wait, forse close and something else. That happens on random calls i am able to anser few calls without any problems and suddenly getting error. Your build nstalled in 16gb class 4 sandisk card, using latest official wwe rom 3.14 + latest 2.15 radio. Installed few games few apps + changed lcd density permanently to 167 and installed AWD launcher. Are you familliar about this problem??? Thank you for your hard work...
[HD2 Android SD Development] ccrowe3:
I really like this ROM. I was surprised at the speed. You would almost not suspect it was running off of an SD card.
[HD2 Android SD Development] cariocap:
Congratulations about this build, it's the fasted one that I tested until now.

I only have had a problem with it. I can't restore only the settings of Alarmdroid and SetCPU. All other applications are restored fine like AndFTP and my site settings. I'm using Titanium backup.

I tested a lot of others builds but this one was the only one I got this problem.

I went back to my SD Rafdroid 4.2 and did a backup of my Alarmdroid and SetCPU profile settings but when I try to restore Alarmdroid settings in the NexusHD2 I've got an FC in process com.splunchy.android.alarmclock. SetCPU restore is fine but I can't see my profiles. It seems that the profiles are active because in the bottom side of main screen of SetCPU I can see 6 symbols of my 6 profiles.

Anyone have had such problem like this ?

Thanks,
[HD2 Android SD Development] gazzacbr:
all working great but..

not sure if its this build or a general problem..

i can connect to my pc and enable USB connection. then i can copy, paste, rename files on the sd card from the pc. then after i disconnect the phone the changes to the card files are not showing up.

is there something i need to do to refresh the sd card files after disconnecting?

EDIT: hmm, seems to be a GUI* problem.. i think what i did at work was to "Turn off USB storage" on the phone first, then take out the usb lead. i think that the pc had not written the index properly. i just tried to disconnect from my windows 7 at home first, then turn off USB on the phone, but in the pull down blind there was still a message saying Disconnect USB storage. so i clicked that and then i got the message about re-loading usb card.

so thats the answer, disconnect at pc, turn off storage on phone, then check message in blind and disconnect and wait for the re-loading message.
