about sdcard as disk drive:

- do not use it :) if you write to disk is always a gamble to corrupt data

- it is a little safer to read then write but still a chance game

explanation:

- sd card is required to boot as android partitions are on sdcard

- when you use it as a disk drive the computer needs exclusive access ( that is why android unmounts sdcard )

- because sdcard is already mounted on a different directory when android mounts sdcard it only mount alias

- when android unmounts it removes mount alias not mount point

- android gives sdcard device to windows exclusive ( or so he tinks )

- windows and android modifies same partitions blocks they see free and FAT (file allocation table)

- this is why in all builds you don't see files only after reboot

nontechnical movie like explanation:

- in wild wild west a cawboy claims a big piece of land, he starts a farm

- in the time he is missing or in other corner of the land another cawboy see the free land and claim it as his own, he brings his cows.

- the 2 cowboys meat each other and claim the other one has stolen his land

- the start a fight

- one or both of them gets killed :)

workaround (i think):

- create 2 partitions on the sdcard, 1st for data and 2nd for android

- put on 2nd partition android files and let 1st as sdcard

- now when android unmounts 1st partition it relay do it and computer can safely write to it.

about possible defects caused by android:

- can shorten battery life. battery charging is tricky stuff, overcharging the battery will shorten its life. that is why i use hastarin 8.5.1 normal (non eb). the driver as i understood is very much htc one with tweaks.

- toying with nand driver can brick your phone :)

- there is probably no other way android can damage your phone

about hardware defects:

- chip meltdown temperature is > 90 celsius ( probably ~120 )

- cpu has a thermal pad the size of a sim card joining it with the case on the side with volume rocker below the battery (hope i remember right)

- high temperatures (>60) should feel like a burn in in the area of the patch

- repeated heating to low temperatures 40-60 celsius may cause bad soldering points to crack or small cracks in soldering to expand to the point it works now and then. this is a manufacturing defect. as far as i know this is the most common manufacturing flaw in electronics.

- if you think your device behave strange now and then prepare for warranty(if you don't have one stick to WM) is just a mater of time

Kernel hastarin 8.5.1 replaced?

Anyone please help with replacing hatarin 8.5.1 onto this version. I tried some times but it does not boot.

Thanks
[HD2 Android SD Development] bjcolema:
The build already has that kernel. If it won't boot, try replacing all but the data img with the original files. Something may have been corrupted.
[HD2 Android SD Development] lilelf87:
is it normal for the phone on this build or any droid build to go up too 300 ma just when im fooling around at menu and stuff? i find it strange that it gets hot when im not even playing games or heavy usage...my set cpu is at 900mhz max..i did overclock it...
[HD2 Android SD Development] mstrk242:
This is very interesting. I'm going to attempt this on a spare card just to see. I do know that windows has trouble seeing sdcards with multiple partitions sometimes, so i hope that doesn't include windows mobile. Assuming that it can, wouldn't I have to change the startup.txt to somehow reflect the second partition with android on it? (I know it's only a theory, but you have me curious now.)
[HD2 Android SD Development] hungtd:
Thanks, this build is so far so good. I reached 2100 by Quadrant, very impressive. However, battery life is so so, consumed 7-8 mAm when being standby.

TMOUS

Rom :Energy

Radio : 2.12
[HD2 Android SD Development] arifqur:
Great explanation man. Hey BTW what happened to the two cowboys? The suspense is killing me. LOL.

All kidding aside these Builds/Roms starting with the desire_cs to the desire_HD2 are simply in a different category to themselves. Amazing speed and snappiness in all areas of the OS and software.

Also I have noticed that after applying the acdb patch, the boot-up time increases and the screen goes black in between the green HTC logo screen and the HTC Quietly Brilliant? Although not to worry as everything still works perfectly.

Planning an update?
[HD2 Android SD Development] lucian777:
Here is what rajkosto said in other thread

"even if you virtually unmount /mnt/sdcard from android on sdcard builds, it's still mounted in /sdcard for the loop mounted partitions to work, so using the usb mass storage mode is NEVER safe.

on my build, sdcard behaves exactly the same as it would on a real android device, hotswap them all you want, use usb mass storage properly etc, and neocore (and other sd froyo apps) didnt install because there was no device-mapper support in kernel, which there now is, so no need to unmount sdcard anymore"

So..disk drive is not safe for data integrity!
[HD2 Android SD Development] beamnhi:
Thanks, mate!

If it does have hastarin 8.5.1, it's seems no need to have any replacement.

Yesterday, I tried replacing, keeping the data.img but failed :rolleye

Strange WIFI Issue

i have a strange issue with my wifi connection.

when i am using DHCP it works fine, but if i used static ip it dose not connect!!!

any suggstions?:confused::confused:
[HD2 Android SD Development] tinuz97:
I hope you have linux,windows cannot make partitions on a sd card.

Also not with a partition manager etc.
[HD2 Android SD Development] kam333:
your not wrong :)

I've gone back to MDJ's build (dhd 4.3), he has this power menu, same performance but big improvement in battery life (usage mA ~200 compared to ~ 400 with this build) & phone doesn't get as hot.

really like this build but mdj's has the edge IMHO, no disrespect intended, I just call it as I see it. (usually gets me onto hot water :rolleyes:)
[HD2 Android SD Development] THANHVO31:
After 6 months "frying" my HD2 with a lot of Android builds, I realize my "brick" recently having strange even in Winmo. Be warned all guys or you may have a 120gr paper weight!:):):)
[HD2 Android SD Development] lucian777:
It's all about kernel...
[HD2 Android SD Development] belsj:
damn, still no 3000
[HD2 Android SD Development] lilelf87:
you wouldnt want to push ur device too hard man...u dun want it come crashing down... desire build definately comsumes more power and heats up much faster then other builds...so be very careful...i just switched back from desire to mui build...snappier much less hot and lower ma...

guys seriously take caution coz watever u do its ur fault alone if ur hd2 fries...devs and chefs are not responsible...
[HD2 Android SD Development] belsj:
Thanks for the warning lilelf87, i'm "playing" with several HTC since 2005. I hope i know what i'm doing.

At this moment No tweaks or setCPU yet.

It's runing 3days with this build and not warmer then normal.
[HD2 Android SD Development] yamensaleh:
Wifi not working with static ip

guys, when i am starting wifi with automatic ip address assigning it wokrs, but if i set a static ip it connects but there is no data, i am sure the settings are correct, any help?

thanks all, solved, i just deleted the network (forget) and added it again, it wokrs now:) thank you

arabic on desire hd builds

hi all

if you want arabic support on this build you need to download the next link

http://www.mediafire.com/?didndhjnpbd2fkn

just extract the downloaded zip file into desire_hd2\root folder from winmo and start android.

Note: you will lose the starting animation (the green HTC on the white backgroud)

please backup your android folder first.
[HD2 Android SD Development] bjcolema:
This is what I was getting consistently before the last update.
[HD2 Android SD Development] greg17477:
The builds seem to behave different for people. I made a comparison today and let the current widget log everything. I browsed the same inet sites, watched the same youtube video and run some quadrant loops. The battery drain and heat was on cedes and mdjs build the same for me.

As you said, its not about disrepecting or dissing someons build or work, i am very happy with everyones work here on xda and thankfull too.. but for me cedes build works best, it just feels fast and smooth, the input reacts instantly. I dont have that feeling on others builds and i test them all :D
[HD2 Android SD Development] puremind:
I second that. I have installed all builds including the latest from MDJ, including the Desire HD builds.

This build is in a league of its own. It is extremely fast and snappy. Battery performance for me is on par.

I get 2,500 Quadrant, but that doesn't mean much to me. What does is that the scrolling and app swtching and overall interface responsiveness is on par with the actual Desire HD.
[HD2 Android SD Development] internauta2000:
The best HD Desire build for this moment... but still can improve.

This is the best HD Desire build for this moment... but still can improve.

- Slow performance when you install or uninstall app's. (A little better with the new initrd.gz, but not entirely) :mad:

- Black screen just before the animation to start the build (after installing new ACDB) :eek:

- Delay when starting some applications (once started going too fast)

- No Advanced Power Menu :(

- Maybe a better battery performance (but that depends to hastarin and new changes in your kernel)

Everything else works perfect and far better than any other build on XDA so far... ;)
[HD2 Android SD Development] fyuecd2:
i am a noob...i read this thread for 3g does starts on bootup and then connection is lost untill i toggle airplane, i read all post but there are patches and fixes scattered about i get confused and some people on here talk so technical i cant understand also. I did the update on first page and it did not help also i did the DNS patch and it did not work, so i guess the 3g is still a work in progress or is there a fix and i missed it somehow?
[HD2 Android SD Development] Fidalgos:
HI lucian777:) I install from your post#4 because on the first time I come to this thread... I only read 'all updates included...' and I begin the download thinking the build of post#4 is the same author of post#1 with updates... but now I know... is different :o and I like it:)

As you say... I don´t have quadrants 2000or+ but on the first boot I have 1777 and now 1556 but I don't have any FCloses. About Market I have the same problem (66 old and some news installed apks) but I think because I have in Applications one 'tick' enable Market install for me:) So... I uninstall the apks I don't want anymore (I only consume some data because I don't see Market install this apks and I use wi-fi to unistall):o

One thing I want ask... Why you don't have any folder Media>Audio and any folder AppsAndroid in your package?...My way is make a copy to SD root... the folder Media>Audio but now I have some duplicated notifications (maybe I have on SD another folder with notifications and rings... I must see)... So... what is the correct way for Media>Audio?

Another ask... When you upgrade your build or manipulated build of post#1:confused: where you go post this?... On this thread or...

Thanks in advance for your reply:)
[HD2 Android SD Development] mstrk242:
I do. I use linux more than windows for the most part.

I got it to the point where I can start haret off the secondary partition, the primary is empty for right now, but stuck at htc logo screen. (I'm assuming that I need to point the rel_path to the proper place, but I'm unsure what the windows mobile mount point would be. I'll keep playing with it.)

**edit**

In windows mobile, with my sdcard partitioned, in the file manager it shows sdcard and sdcard 2, so it can read them.
[HD2 Android SD Development] kam333:
Fair Points :)

i did a fresh install twice & battery drain was still high, even after a full drain & full charge. Anyhow, still a great rom, but i really couldnt live with the boot sound (searched & posted, but could find a way to disable) & the big 1 for me was no advance power menu, i kind of got used to that from other builds.

horses for courses n all that stuff ;)

Still... Enjoy

Kam
[HD2 Android SD Development] nobnut:
Download 'Silent Boot' from the Market...

Thank me later :p
[HD2 Android SD Development] :
No need for this. Seems a fix isn't what you wanted. you wanted a work around. Sorry bout that.
[HD2 Android SD Development] nobnut:
Ummm...

Look at the post above yours.

:rolleyes:
[HD2 Android SD Development] :
Roll your eyes elsewhere. No need to be rude.

I offered a fix. You offered a work around. :rolleyes:

I actually hesitated to post that "fix" too. Seeing as people here are ungrateful/rude. Seems that will be my last post to ever help out around here. Thanks buddy.
[HD2 Android SD Development] nobnut:
You offered an ill-informed bodge.

Should he delete every file on his SD card in turn until he strikes gold?

By the way, rolling my eyes isn't rude... it is a comment on your level of technical capability.

Don't thank me. I don't want or need it. Cheers.
[HD2 Android SD Development] :
Wow. You really are a jerk. Good luck getting along with the real world with the prick type attitude. And rolling your eyes is rude. It's disrespectful to the person it's being done to.

I offered a fix. Period. I fixed this before in less than five minutes and no need for a app to do it. Maybe some people like fixes instead of a work around? I do. Maybe he does too? Whatever though. Maybe you didn't like it that you were the only one to try and help him and did a work around and I actually told him how to do it?

Anyways. Have fun.
[HD2 Android SD Development] kam333:
nobnut, The_Biz...

thanks for the suggestions, I'm using mdj's build without the sound, but il keep them in mind for future ref. ;)

cheers

Kam

p.s.

@The_Biz, it ain't so serious, just a little forum banter. :)
[HD2 Android SD Development] clio94:
I like this build.It is really fast,very fast.Apps from market are downloaded like real android devices.lag when installing exists,but i dont really care of it.I dont download apps all the time.I like the smooth operation of this build.At first i thought that the big scores in quadrant were plasmatic but after some use,i see that there is difference in perfomance.I am using latest mdj kernel 7.5 and everything work fine.Thank you for your excellent work :)
[HD2 Android SD Development] buzz killington:
I guess it really is very different for everybody. For me it's the lowest power consuming build I've tried. Yesterday during 8.5 hours of standby it only used 4%! Here's the logs to prove it.

Still had plenty of juce left after 1 day and 15 hours
[HD2 Android SD Development] kam333:
decent!

that's the sort of drainage I'm getting now ive changed to mdj, but wasn't happening before.

the strange thing is, there are some on his thread stating high batt' drain.

too many variable's to figure it out.

:confused:
[HD2 Android SD Development] nokn956120:
Smashing job

I was on this build the day before last and the camcorder fix came out so I came off this build to try that (not mentioning the build lol). The other build had the camcorder working but was overall slow. I couldnt hear messages being delivered and the sound was low in general.

Currently booting this build back up as it is the best HD build I have seen so far and believe me, my wife moans everyday when I put a new build on so lets just say I have tried them all. It is very smooth and a pleasure to use. With the icon packs, default.acdb fix and camcorder fix, this is the best Desire HD build out. I like the customised and coloured interface on the Core HD build, this desire_hd2 build is smoother and customizing the interface similar to Core would be the only way I can see to improve this build. Netherless, this I feel is the best yet.

Just a quick shout to all chefs, you do great work and working together can only bring better, more stable builds for all. This is not about who's is better, its is about bringing class roms and builds to the wonderful HD2 device. Thumbs up to you all. :D
[HD2 Android SD Development] LondonTownGuy:
Boot up sound

this is file: android_audio.mp3 located: /system/customize/resource

If you rename it or replace with silent file should become silent.
[HD2 Android SD Development] cedesmith:
updated ip-up, ip-down and options.smd for same version (0.7) of ril wrapper

it should work for everyone now.

if someone has tried 2 partitions on the card you have to add in startup.txt cmd line loop_partition=mmcblk0p2 else init still searches 1st partition
[HD2 Android SD Development] rafpigna:
What those update will fix?

I need them if I used the lucian77 file on post #4 ?
[HD2 Android SD Development] cedesmith:
if you have problems with mobile data.

as of now i doubt lucian has updated his post
[HD2 Android SD Development] fiftyz:
Did someone ecperienced random restarts?

Did someone experienced no sound at all and it solves only with restart? (this happened to me only with this build)
[HD2 Android SD Development] rafpigna:
Ok thanks. ATM no problem with mobile data, I will skip the update for now.

Thanks for the bulild.. seems quite stable for now (48 hours). I experienced a total freeze during gps navigation with google navigator, I had to remove the battery to restart.. I will do more tests.
[HD2 Android SD Development] KrewsialNL:
the only problem i have with mobile data is that when i activate it and turn of the screen, i dont have a working connection. When i close the connetion and start it again, it works fine.

I am finally done completely installing the phone and this build is running without any flaws for three days now :)

I love this one, the best HD build out there, at least for me!
[HD2 Android SD Development] 2happy:
TO CEDESMITH:)

is there any chance you can upload a new desire-hd file with all the updates silent start up,proper data connections and all the updates which you uploaded into one file and call it beta2 version,so others can download the beta2 file and write their outcomes of the new beta2.it seems everyone having different issues on their hd2 phone.so far some people are happy,some are not.
[HD2 Android SD Development] pkchips:
Is there any way to undo the updates?

I did all 4 at once and one of the updates has caused both my wifi and 3g/data to stop working. (I'm guessing its the ril wrapper)
[HD2 Android SD Development] puremind:
I agree, that would be most appreciated. Been looking everyday for an update.

Here are the issues I have had with the buid:

Once or twice didn't boot and got stuck on HTC screen

Like everyone else, can becomes slightly jerky when applications are being installed

Like on other builds I cant get the route widget to work. "cannot find map data" even after it has downloaded the file. It somehow only worked today evening, after many tries had failed, may have been due to using WiFi instead of data connection

I had a few network errors in HTC Hub today when the phone was plugged in and overclocked: "cannot find HTC servers", this was intermitant, so I thought this might be due to overclocking. Toning down the overclocking seemed to fix it. I had a profile to work on max overclocking when pugged in.

My data connection seems to fade after screen has been turned off. It seems to fade selectively: it may not work in the Internet application, but may work in market place or other apps using the internet connection. It seems to start working again when I switch off WiFi or turn planemode on and off, though in 2 instances I couldn't get to start again and had to reboot. This could be due to my downclocking when screen is off through SetCPU profile, although I didn't have such issues in MDJ'S equivalent build

My main issue is the data connection one though, I don't really care about the rest. I will wait until there is an updated version that doesn't require any frankensteining. I don't want to mis the speed anymore.
[HD2 Android SD Development] mstrk242:
I tried this and it still doesn't seem to work. Folder name is android on the second partition of the sd card. Startup.txt line is as follows: set cmdline "loop_partition=mmcblk0p1 rel_path=Android nand_boot=0 "

Did I input something wrong here?
[HD2 Android SD Development] andylhchen:
I also have issue with chinese files not displaying correctly, great build otherwise :)
[HD2 Android SD Development] 2happy:
THANKS

Thank you puremind:)

for pointing out with details whats everyone having so far.i am positive that cedesmith will upload new build with all the updates and work on some of the important issues on its (beta2)version.i am looking forward to it.all the respect for the developers trying hard to perfect their builds.wishing them good luck :)
[HD2 Android SD Development] dr_hardware:
the best!!!!

this build is the fastest DHD build ever... and with all updates installed works great!!!

:D:D:D
[HD2 Android SD Development] confar:
cedesmith, lucian777:

with this build version of desire_hd2 - all fixes incluided and new initrd.gz for data corruption is "secure" if suddenly my hd2 shutdown for low battery?

i tested 3 hd builds: mccm1.2, mdeejay4.3, and this (cedesmith beta_hd2) and this is the best in data connection, faster, best points in quadrant and linpak... but my information is important and i want to preffer a build stable....

i know that this build is beta... but works very well... but i need that my information be secure...

sorry by my bad english... regrats and thanks
[HD2 Android SD Development] internauta2000:
That is for you a secure ROM? The only relatively safe Android phone is a native Android, and can be purchased new from a store. I think that you demand a lot from developers... :confused:
[HD2 Android SD Development] confar:
i talking about "secure" build.... please read well

so, in my experiencie... of course there are androids builds "secure", i named "secure" like stable.... with less possibility that my data information dont lost...

i tested many builds since august... in all i have goods results... but i this seems that is better in all... only i want to know that is secure than others builds....

i dont want to create controversy.... sorry
[HD2 Android SD Development] confar:
my question is for this warning... i want to know if still is necesary to backup of data.img

in others builds this is no neccesary
[HD2 Android SD Development] internauta2000:
I understand ... I think you should wait some time ... Desire HD generation has little time in HD2... :rolleyes:
[HD2 Android SD Development] hastarin:
I had thought about asking for the same thing. But given his update system it's hardly needed.

I've just installed this with all the updates from his 2nd post, plus my current kernel (not released yet but will release in a compatible zip when I do), and the latest Titanium Backup APK (via AndroidApps) folder.

Now I'm restoring my backups. :) It really couldn't have been any easier!

I can't wait for the backups to finish so I can play. :D

Great work cedesmith. I do agree we'd all benefit if more build authors switched to this way of doing things!

Time to update my signature I think. ;)
[HD2 Android SD Development] lucian777:
No is no need to backup data with the new Initrd post #4
[HD2 Android SD Development] beamnhi:
Does anyone have lights sensor works in this version? I set it to Auto brightness but it does nothing.

Thanks for your help,
[HD2 Android SD Development] mmduluth:
Mine works perfectly. I'm pretty sure that's kernel related so if your still on hastarins it should work fine...
[HD2 Android SD Development] beamnhi:
Thanks, mates!

I keep the original kernel as in the fixed version.

I saw in system/lip/hw 2 files: lights.htcleo.so and lights.qsd8k.so ; the build.prop shows ro.board.platform=qsd8k

Is that information correct?
