Could you please tell us what is the battery drain with this kernel in comparison with the prj 0.4. I use the original one (prj 0.4) and my battery drains with less than a percent per hour in stand by mode. For instance, for 10 hours, fully charged battery goes down to 93 %, which is normal in my opinion but when I start useing the phone, it doesn't matter if I make phone calls or browse the internet, the battery goes down very quick. In regard of the performance, I cannot ask for more! Everything works perfectly well and it is a real pleasure to touch the phone.

Of course if someone else made the switch of kernels may share his impressions, it would be good for all of us who use this wonderfull ROM.

Best regards,

Z.

Hi. Can somebody who using this rom please check if this rom can see & connect to adhoc wifi? I tried the original projection rom some time ago but it doesn't see adhoc wifi. Wondering if there's a fix for it
[HD2 Android NAND Development] maxld:
How long is the first boot? I am waiting for 10 minutes still stuck at HTC logo. Done everything properly - flashed CWM from zip, made SD partitions and then flashed rom from zip. Any ideas?
[HD2 Android NAND Development] alik713:
what, no option to delete one's own moronic posts?

Oh, well. At least there's self-flogging! :)

On another note, speed is amazing!

Exactly what it should be!

No lag anywhere. Swype, Bonsai Blast, all working perfectly.

Thanks, man!

It is pretty impressive how, despite having just as little RAM as all the other builds (right around 110Mb or so), this build actually has many more apps running, and, still, the management of the RAM is top notch!
[HD2 Android NAND Development] ahmetdamar:
Thank you. What MHz? 1536Mhz OK?
[HD2 Android NAND Development] nemuro:
I tried the CWM partitioning just as in the guide and on first boot I had no space left whatsoever and I couldn't use the rom because of constant fc's.

After that I used gparted to make my own 512 then 1024 mb ext4 partitions and right after boot I applied the rafpigna 1.7oc and gl kernel v6.

In both the cases I am left with 111 internal storage space.

What can I do?
[HD2 Android NAND Development] RolandCruise:
That's the normal behavior...what is the problem?
[HD2 Android NAND Development] feloccio:
How do you get this nice statistics?
[HD2 Android NAND Development] RolandCruise:
skink, yesterday I switched to your build from prj's one because after installing something like around 100+ apps I got the "not enough storage" message :D

Now I have the same apps installed and I still have 50mb of internal free storage and this is good, but in anticipation of the "not enough space" situation again, I wanted to ask you if the command

a2sd datasd

from the terminal emulator has to be given as root or as normal user...?

I ask this because, yesterday, soon after the flash I used the script in extras.zip from the pc and I had to re-flash because nothing worked after the boot...

Thaks a lot ;)
[HD2 Android NAND Development] RolandCruise:
And what is this story that I just made a backup through CWM and it destroyed my home screen widgets?? It is completely blank...! And every home screen profile preset is blank too...is there a way to fix this???

Shouldn't CWM a secure way to make backups and restores???
[HD2 Android NAND Development] nemuro:
@RolandCruise Well the /system is very tight. Won't installing and running apps create files there and eventually run out of space?

@feloccio: qtadb.wordpress.com
[HD2 Android NAND Development] RolandCruise:
With app2sd you have to install more than 100 apps to run out of space...or some very big apps like more than 20mb each ;)

Anyway the script in the extras.zip should put on the sd what still remains on nand, but I'll try it when I run again out space despite app2sd too :)
[HD2 Android NAND Development] semkar:
i love this rom but i am desperate for power widget control on notification bar.can anybody help.
[HD2 Android NAND Development] Eddy9000:
Hello, I got this ROM, it's so good, thank you, great work!

I have a question, like I wrote in this thread http://xdaforums.com/showthread.php?t=978406:

I need an app for Android that allow my data connection just when I request, for example when I use Internet, Meteo, Market and so on...the rest of time data connection has to be down!

For example JuiceDefender does it, but not like I want...when the display is black, the data connection is off, but it's ok when I turn on the display...but I don't want this...I want that my data connection starts just lunching specific apps!

Thank you!
[HD2 Android NAND Development] RolandCruise:
I was looking for something like this too (to have data connection "on demand" like on wm), but all I found is JuiceDefender...like you.

Anyway, JuiceDefender can be set to enable data connection when specific apps run too, but with the limit of 4 apps that can be chosen as "triggers". ;)

I think UltimaJuice is needed to unlock all the features that are greyed out in the free version and remove the limit of 4 apps... :)
[HD2 Android NAND Development] timmy1980:
I just tried this kernel too but I lost mobile data... still had data icon (3g/H/G) but no actual data.

Anyone else have this issue?

Great ROM by the way!! Just come back from WP7!

Thanks
[HD2 Android NAND Development] RolandCruise:
Yes, I had this issue with this kernel and with rafpigna's one and wasn't able to solve it...

Now I am using tytung r6 kernel and it's working great. ;)
[HD2 Android NAND Development] $t0Rm:
do your notifications work?
[HD2 Android NAND Development] feloccio:
Is there any noticeable improvement with the tytung kernel? I am quite happy with the speed of the prj kernel but i would always change for a longer battery life.

I made some hd2 artwork with android sense that i would like to share.

You might find them as well on my german thread for skinks clean desire.
[HD2 Android NAND Development] RolandCruise:
if you mean led notifications then yes, they are working without blinking as with prj's v0.4 kernel ;)
[HD2 Android NAND Development] Dizzle:
Roland, you tried installing the rapfinga 1.8 via cwm and it doesn't fully work? I was considering trying but if kernel can't be changed I might not bother..
[HD2 Android NAND Development] RolandCruise:
I switched to tytung's kernel just today, so I still can't say too much about battery life (at first glance it seems to be the same anyway), but I can say that the speed is virtually the same with the advantage of the opportunity to overclock a little bit to 1190MHz (and in this case it becomes a little bit more responsive).

By default it is set at 998MHz with the interactive governor, but you can change governor and cpu frequency through setcpu as usual ;)

P.s.: Very nice artwork, feloccio! ;) :)
[HD2 Android NAND Development] RolandCruise:
yes, I installed it via cwm and also via adb yesterday when I still was on prj's rom. In both cases data connection didn't work and I didn't know how to solve this issue. The same problem was with g.lewarne kernel (and this is why I didn't try his latest kernel). So I always went back to prj's one.

Of course you can change kernel whenever you want, but I have to say that I had problem to change kernel with skink's rom through adb or a terminal emulator.

Now that I'm on skink's rom I can change kernel "the cwm way" only :)

So I don't know how to come back to prj's one without a cwm zip of the kernel if not by restoring my system partition through cwm recovery restore option, thanks to the backup I did yesterday :D

Anyway, tytung's r6 kernel is working great, so maybe I won't need to switch back to prj's v0.4 one ;)
[HD2 Android NAND Development] Dizzle:
Thanks for the reply. I might try this build. I guess its pretty much identical to prj's build.
[HD2 Android NAND Development] timmy1980:
Thanks for the reply. I'm trying that kernel now but have the same experience as mentioned by zgeorgiev with both the original kernel and tytung r6 which is that battery drain is low when screen is off but as soon as I start using my phone for anything I can literally watch the battery drop in front of my eyes... if not for this excessive drainage this Rom would be perfect for me!
[HD2 Android NAND Development] Dizzle:
Just tried Rapfinga's 1.8 on this build and data doesn't work. Everything else seems to. This was the same issue that was on prj's build. Shame really as Rapfinga's kernel is the best at the moment (imho).
[HD2 Android NAND Development] RolandCruise:
yesterday I didn't notice any difference in battery drain while using the phone too...anyway, it's a too little time to tell, so I'll continue to use tytung kernel and pay attention to this aspect during the next days ;)

If I can give a suggestion, try installing JuiceDefender. The biggest (after the cpu and the screen) culprit of the battery drain is the data connection imho and this app can really help. ;)

In the meantime, if someone could make a cwm zip of the prj's v0.4 kernel would be greatly appreciated :D

P.s.: and honestly, I don't remember of a too different battery drainage under wm...we should consider that now that we have android we are using a lot more our phones than with wm ;)

Now, I can surf the web much more better, use a lot of apps, check emails a lot better, read ebooks and office documents a lot better etc. etc. than under wm, so a real comparison should be done trying to have the same kind of usage we were having with wm (personally, phone calls, few apps that requested internet, emails just when needed because it was a real pain to check them, ebooks reading...).

I think that under quite the same conditions the difference in battery life will be not too big, although android could still be the one that drain more. ;)
[HD2 Android NAND Development] feloccio:
This is a psychological effect caused by the percented battery. With the stock htc battery icon you wouldnt see that (and thats the reason why htc doesnt provide accurate battery level, not even in settings)

Your battery level isnt showing the right level, especially when charged overnight.

Look here: http://xdaforums.com/showthread.php?t=871051
[HD2 Android NAND Development] RolandCruise:
This is why I'd really like to have the opportunity to switch to the standard battery icon without percentage...I think this could be done through a cwm zip...what do you think, skink?

I think it would be nice if we could have a standard icon zip and a percentage one to switch between the two according to everyone's need/taste ;)
[HD2 Android NAND Development] feloccio:
Does anybody knows a fix to answer calls ONLY with the hard buttons? Often I accept/reject calls while pulling the phone out of the pocket. The screen is too sensitive. Maybe there is an app or a script for this.

Edit: I actually like the percented battery because most if the time it shows accurate battery level. The thing is that you have to know about the way the battery level is displayed and the way the it is charged. (as described in my previously posted link)

If you experience fast dropping battery level you might plug it in again.
[HD2 Android NAND Development] athulag:
Just some information for those who are interested:

I tested RAFPIGNA 1.8 OC Kernel (going from Prj 0.4) but had issues with Data connection not working. Everything else including Wifi worked fine.

Then I downgraded to RAFPIGNA 1.7 OC and everything seems to be working fine.

But basically I cannot tell a difference battery usage wise (the only reason why I would want to try something new). The intereactive Governor is responsive and feels good. I do not intend to use the Overclocking feature.

found the fix for the Data issue on RAFPIGNA 1.8 OC:

====

when you install 1.8 kernel it does not install the script \system\etc\init.d\01modules. This script is only in 1.7 version.

So the "msm_rmnet.ko" was not loaded.

After I installed 1.7 and then install 1.8 everything is working

Alternatively you can copy the file from 1.7 OC using adb push
[HD2 Android NAND Development] KrewsialNL:
Am i doing something wrong? I did everthing according to manual, though the ext partition made with cwr does not work I think as the amount of free space is just over 100MB. Shouldnt that be more when you have a 1gb ext partition?

ROM is the best out there by the way. Snappy and good battery :)
[HD2 Android NAND Development] RolandCruise:
a2sd installs apps on the ext partition, but not everything that is in /data is moved to the microsd and this result in a decrease of the internal storage freespace in any case, but much less than what happen having everything on nand.

You can check that your ext partiotin is being actually used through Titanium Backup, an app you can find in the market and will show you internal, sd and sd-ext (a2sd) storage ;)
[HD2 Android NAND Development] KrewsialNL:
Oh, I really havent been paying attention! Completely read over the fact its apps2sd haha.

Thanks for making me see buddy ;-)
[HD2 Android NAND Development] mylove299:
Sorry does this build full root, cuzz i cant modify any find on system folder, root explorer say: file is read only How can i fix it?? thanks
[HD2 Android NAND Development] RolandCruise:
if you are using root explorer then you will see a small button on the top left that says "Mount R/W" to mount with read and write permissions that particular folder in which you are at that specific moment...

Anyway, the rom is rooted ;)
[HD2 Android NAND Development] mylove299:
thanks for quick reply. it work ;)

skins, skin picker from stock HTC Desire hd

Hi, I have htc desire hd and also htc hd2 512 with your rom , everything is working great but missing one thing , the skins and skin picker from original htc desire hd, skins like Wood, Slate, and Metal

Is it possible to install it to your rom and how?
[HD2 Android NAND Development] feloccio:
If the Desire gets an update to Sense 2.x maybe. Otherwise you will have to try a (slow) Desire hd/z build.
[HD2 Android NAND Development] mylove299:
Great room i have been use . thanks alot. waiting for update
[HD2 Android NAND Development] rubikum:
For those who would like to know, I got rid of the wakeup and unlock lag, by using tytung's r6 kernel:D

And build is still smooth and stable:)

Phone freezing under high CPU load

Hi Gents,

first of all many thanks to Skink and his mates for the best Android ROM for HD2 ever :), which makes me totally addicted to the phone :)

However I have recently discovered the phone is regularly freezing (just hangs) when I keep playing with the phone for longer time (20 minutes or so), i.e. CPU is loaded at 998 MHz most of the time and its temperature conseqently climbs to 35-39 Celsius degrees. It looks like CPU overheating to me, since battery is quite cool, while the bottom of phone is abnormally warm.

I have already tried two Radios (2.12 and 2.15) but with no improvement. The same story with swapping original batteries. Not sure, whether this is a clean proof, that HW is faulty, or whether it may be due to be some SW control in Android OS.

Moreover, the issue occurs regardless the fact I use SetCPU features or not.

Many thanks for you advice.

Monsoon
[HD2 Android NAND Development] zgeorgiev:
And how is the battery dealing with this kernel?
[HD2 Android NAND Development] mylove299:
always get 3mA when screen off after about 20 second, very low battery drain( i am using tytung r6 kernel) ;)
[HD2 Android NAND Development] zgeorgiev:
Do you use this one tytung_r6 or this one tytung_r6_oldcam ? It is important to know before I start flashing :)
[HD2 Android NAND Development] RolandCruise:
Well...I am using tytung_r6 kernel for a few days too and I still have the wake up lag. :confused:
[HD2 Android NAND Development] RolandCruise:
tytung's third post of his rom thread says that oldcam kernel is for nexus/old camera libs roms...so we should use tytung_r6 for new/desire camera libs.

I think... :)

I am using the first one (not oldcam), anyway, and battery drain is very good ;)
[HD2 Android NAND Development] creed:
Getting white outs!?

Ok so I really like this ROM, it's great, however I'm having an occasional issue where the screen goes white BUT the phone still operates and I can just about make out the display.

Anyone else experiencing anything like this?

It's a relatively small issue because everything else about the ROM is perfect, a quick reboot and it's back to normal but obviously I'd like not to be having this issue at all!
[HD2 Android NAND Development] zgeorgiev:
Ok, I changed the kernel to tytung_r6. So far it all looks normal. Everything is fast and smooth. In a few days I can share a comment on the battery drain.

About the lag when the phone wakes up - it is still there but its time is decreased to minimum and in my opinion it is a very minor bug which I can live with. What is more important to me is the battery life. Can someone share experience if this ROM works with ext4 partition instead of ext3 and in case it does, how does it reflect on the battery life? I read somewhere that it is good for the battery but I am not sure... What do you think about it?

Best regards to all of you
[HD2 Android NAND Development] mylove299:
I am using tytung r6 kernel and ext4, till now 18 hours left with nomal use ,my bettery show 54 %. Great battery life.
[HD2 Android NAND Development] mylove299:
I am using tytung r6 not old cam.
[HD2 Android NAND Development] zgeorgiev:
How did you manage to run it on ext4 formated sd card? I used Gparted and I made a ext4 partition and a fat32 partition. Both of them are primary partitions. Then I put the sd card in the phone and start from the beginning - task29 ->magldr 1.13 ->Clockwork Mod 1.3 -> Install from zip. After I receive a message that it was installed, I reboot and all I get is the HTC splashscreen. Nothing more. Do I miss something?
[HD2 Android NAND Development] enrierosi:
The same for me everything work fine! This is an superior Rom!
[HD2 Android NAND Development] RolandCruise:
Did you "install from zip" the rom first and tytung's kernel after?

...before booting the phone?

Maybe, if you are making a fresh install, this could be the right procedure after fotmatting the ext4 partition on the microsd ;)
[HD2 Android NAND Development] zgeorgiev:
That made it work. Thanks a lot, my friend!
[HD2 Android NAND Development] Sanien:
Move Data2Sd

Hi

Im confused.

Why do you ever need to use the script to move data2SD when it already is happening automatically?
[HD2 Android NAND Development] MrMiyagi:
Anyone have a CWM Zip for the original prj kernel for this ROM?

I want to try some of the other kernels but would like to be able to come back to this one if needed.

TIA
[HD2 Android NAND Development] kraz_zay:
The BEST AND STABLE ROM so far......

:DGuys i've tried the tytung_r6 kernel.... and so far so good. infact BETTER battery life... thanks to all chefs for making these BEAUTIFUL rom.... IT is THE most Stable rom... i've tried n sticking with it.:D
[HD2 Android NAND Development] MrMiyagi:
Sounds good. Do you have a link to the ZIP for the kernel?

Also how were you planning to go back to the prj kernel if it all went wrong?
[HD2 Android NAND Development] zgeorgiev:
Just make a fresh install without the new kernel and that's it. You do not have to worry so much and just give it a try. :p

If you have any questions about the procedure, do not hesitate to ask.

Best regards

PS Here is the link.
[HD2 Android NAND Development] MrMiyagi:
Not exactly worried but bored og flashing ROMS this week ;-) Was hoping there was a prj kernel zip I could just flash back instead of the whole ROM.

Cheers for the link.
[HD2 Android NAND Development] RolandCruise:
you can always make a cwm backup and, if something goes wrong, restore it ;)

anyway, tytung's r6 kernel is great and, in my opinion, it can be considered as the natural evolution of prj's one.

And...I'm quite sure you won't need to go back after installing tytung's r6 ;)
[HD2 Android NAND Development] MrMiyagi:
Yep, flashed the tytung r6 kernel. Quadrant score broke 1400 (1464 to be exact) for the first time in this ROM!

Nice so far. Looking forward to seeing if battery life is any better :D
[HD2 Android NAND Development] MrMiyagi:
So, another query.

Just installed this ROM on a friends HD2 for him (the LEO512).

Partitioned the SD card 3GB Fat32 and 1GB EXT4

Then Flashed the ROM from CWM (no reboot of phone afterwards, stayed in CWM)

Then Flashed the tytungR6 kernel

Then rebooted phone.

All looks good, I can see the folders have been created in the ext4 partion (dalvick cache etc).

Only issue is that internal memory still shows as 110MB free? I would expect this from an EXT3 partition but not and EXT4 one. Is this expected? Have I done something wrong?

TIA
[HD2 Android NAND Development] RolandCruise:
There is no reason why ext3 and ext4 should behave differently regarding internal memory. They are two file systems, with ext4 being the "successor" of ext3, almost like ntfs was the successor of fat... (well...very almost... :) )

So, you didn't anything wrong, the only difference between the two should be a better performance of ext4 vs ext3. ;)
[HD2 Android NAND Development] zgeorgiev:
No, nothing wrong in my opinion. You did the whole procedure exactly as I had done it yesterday.

Regarding the battery drain, I unplugged my phone yesterday at 1 am and now (20 hours later) I have 68% battery left but I barely used the phone today. I made only a few phone calls and some internet browsing. Ater all, this is a good battery usage in my opinion.
[HD2 Android NAND Development] darklord981:
Hey guys

I've just migrated from prj's build and been really enjoying the stability and smoothness of the rom.

My issue is the battery life which is worse than prj's build. I see a percent go down for every minute I use the phone. Let me provide you guys with the details.

Usage: wifi is on. Sync, gps is off. No live wallpaper.

Radio: latest 50.14

Kernel: tytung r6

also i installed exactly the way illustrated in the op.

hi

first of all great android :)

second i have a little problem after downloading a few things from the market

my hd2 came on the white screen with htc on it kept on writing

quitly briliant on and on and on again

so i restarted it but now my market is gone

can someone help me ASAP

greets
[HD2 Android NAND Development] yzumtrp:
Hi All,

I found this ROM doesnt support extend battery, is it possible for fix this bug in the next update?
[HD2 Android NAND Development] mylove299:
It depend on the kernel not rom build, let try another kernel with support ext battery.

Does this build continue ??? Long time without update :(
[HD2 Android NAND Development] MaFake:
Nice and fast release.

I have the same problem with the original big akku pack from htc...
[HD2 Android NAND Development] Lestko:
For extended battery try kernel from this address:

nexus-hd2.googlecode.com/files/kernel_tytung_r6_update.zip

Installation:

Place your downloaded files in the SD card.

Enter MAGLDR. (hold "Power" button during boot)

Choose AD Recovery (in MAGLDR 1.13) or Boot AD SD (in MAGLDR 1.11~1.13) to enter the ClockworkMod Recovery.

Choose install zip from sdcard and locate your downloaded file to finish the installation.

All done.

Everything works, but after install I'v got message about little space, if so, try method from 1-st post:

"If you still need more space on internal storage you can move /data/data folder to SD ext partition. This can be done using script data2sd.cmd from extras.zip or if you have some terminal application installed on your phone you can use command: “a2sd datasd”."
[HD2 Android NAND Development] raven_raven:
As far as I know, only tytung kernel supports extended battery if it comes to NAND ROMs. Just wanted to add :).
