Failing at the first hurdle. Trying to find SPL:

For item 3 >> Turn phone off > Press and hold Volume down button >briefly press release power button >SPL version is displayed on bootloader screen (Red/Green/White)

doesn't work.

I have latest O2 ROM 1.72, Radio version 2.07.51
[HD2 Android SD Development] despy1989:
Can u please tell me the exact version of spl u have
[HD2 Android SD Development] despy1989:
Have to keep the vol down button pressed all the time ..while holding the vol pressed briefly press and release power button ..u now will be able to see bootloader screen....
[HD2 Android SD Development] despy1989:
If you have a SD card of more than 4 gb then should be fine . Android ROM from SD card does not use any PHONE MEMORY. the space available to android Rom depends on the size of data image which you chose during installation. This is stored on your SD card itself. Also if you choose a data image of 1gb during first install you should have no problems at all.

:)
[HD2 Android SD Development] Mus:
Exactly what I'm doing. Just goes to the lockscreen as usual...
[HD2 Android SD Development] despy1989:
switch phone OFF completely to start with > While the phone is off hold volume down button and keep it pressed > now switch phone on by briefly pressing and releasing the power button > kepp holding the volume button down till bootloader screen comes on

This cannot fail .......
[HD2 Android SD Development] Mus:
OK, I got it. I wasn't aware of how to totally power off. Thanks. I have SPL 1.66

Getting out of the bootloader requires a soft reset, right ...?
[HD2 Android SD Development] despy1989:
I had the same problem with SPL and here is what worked for me

From the Stock ROM thread download a Stock HTC ROM (e.g 1.66) and flash it as you would in Stock ROM (this down grades your SPL and also your RADIO )

Once done you need to now run the HSPL package and choose HSPL 2.08 (not 2.08.0000)

Once you have HSPL you can then flash any Radio / ROM of your choice as long as the RADIO is compatible with Android

If you ever need to take HSPL off then go thry HSPL instuctions to reflash SPL 2.08.0000 and then just flash Stock 3.14 ROM and its sorted.

However the other simpler option is to go for the Stock ROM 3.14 which will give you the radio and you then dont need anything else...

Hope it helps.

Can use SD card in Android

Hi, i'm kinda new to al this.

I just bought an htc hd2 yesterday, and I installed Android on it with the sd method.

But i have a little problem, when I boot into android my SD card disconnects.

so i can't use the camera or play music. how can i solve this?

Question before flashing

Hello,

This thread is very helpful for new people like me, it made almost everything super clear! I have just some minor questions :

1) Is it possible to do this all on a HD2 with Vodafone Rom ? ( Rom version: 3.14.172.3 (04666) NLD, Radioversion: 2.15.50.14, SPL version: 3.03.000)

2) Will I be able to turn everything back to stock for warranty?

3) The data.img file is there an disadvantage for having a bigger one? For example 1gig in stead of 512 mb.

Thanks in advance!
[HD2 Android SD Development] zarathustrax:
You're booting into android from windows mobile using haret.exe? What android build are you using? Information about your setup is needed for someone to help. Also, read through the thread that you got the build from to see if anything is said about this.
[HD2 Android SD Development] despy1989:
1) Yes : you dont need anything else just go straight to Step B

2) Yes : the android does not make any changes to your win mo settings and will be gone completely once you wipe your sd card :). the only thing that voids warranty is hspl but you wont need that as radio is compatible in your rom plus hspl is easy enough to remove even if you install it.....

3) Data.img : The size is basically what determines how much space your system has to play with :). if you are installing a lot of apps etc then you may run out of space with a img size of 512mb. If you have enough space on your sd card then choose the 1 gb
[HD2 Android SD Development] Mus:
It seems easier to go for the HTC latest ROM but do I lose anything by not just updating the Radio on an O2 UK ROM...?

Thanks
[HD2 Android SD Development] Mus:
Should I even be trying to replace the O2 ROM? If so where can I get the stock if the HTC won't let me download it?

Thanks
[HD2 Android SD Development] despy1989:
You will definitely need HSPL first (link on 1st page), Task 29 format is optional.

Radio upgrade is required( Link http://xdaforums.com/showthread.php?t=611787)

or

If you want to flash the leo custom rom 3.14 here is the link (it automatically upgrades your radio anyway so you can just go to this after you install hspl)

About to get a used HD2 to be able to "dual boot" WP7 and Android 2.2. Is the HD2 with Froyo as good an Android phone as the Samsung Galaxy S or there are some unavoidable limitations? Thanks !
[HD2 Android SD Development] zarathustrax:
Battery life isn't nearly as good as a native android device. Also takes more work and time learning how set up device and work through any bugs you come across. It is a port that the hd2 is running, so obviously its not going to run as well as a native phone... well atleast not without putting a lot of work into it.
[HD2 Android SD Development] webvan:
That was honest, thanks. Battery life is going to bit of a concern I suppose, especially with the rather paltry 1230mAh they are using. Does Google Maps Navigation work ok, including the 3D buildings in map mode?
[HD2 Android SD Development] zarathustrax:
Yeah, most apps work as they are suppose to... occasionally there's problems with keeping web connections and other problems and issues in the different android builds, but there's usually workarounds, so it takes reading and learning to get things working the way you want. No build is perfect... they all have different strengths and weaknesses and issues, so you'll probably want to try out several builds until you find one that works for you.

Also, there's no guarantee that wp7 will continue to work after ms updates it... they may put a stop to it working or we may be stuck using an old wp7 build... and to get live services working in wp7, you have to hack the registry so it looks like a hd7 to ms live services, then call ms to get an activation code telling them you have a hd7, and from what I've been hearing is that its getting much harder to do now because ms is starting to ask for proof of purchases and imei numbers... they probably have caught on to what's going on. Also, just unlocking the phone to make registry changes have been causing a lot of issues for people... so getting wp7 to properly work may be pretty difficult. It was easy the first time I did it, and I called ms the first day the port was released to get my activation code, so that wasn't an issue for me. But when I reset my phone so I could partition my sd card, I have a difficult time getting it to unlock again... took me about 5 hours of working on it until I got it unlocked again. It takes a lot of learning to do it properly and get it working good.

So if you're not up to spending hours upon hours reading and playing with your phone to get it working the way you want, then the hd2 may not be the phone for you. But once you know what you're doing and get it setup good, it works great.

Also, if you plan on using wp7, get yourself a class 2 sandisk microsd. Wp7 is very picky about the sd card that works with it... some work well, some make it buggy and laggy, some wont work at all. Sandisk class 2 seems to give the best chance of working well.
[HD2 Android SD Development] webvan:
Thanks again, food for thought certainly, didn't know about the actvation process for "Live", and ater some reading it seems it's not just for Live Messenger lke it used to be...might be a better idea to get an HD7 and then slap Froyo on it...but that doesn't seem like an option, at least for now based on http://xdaforums.com/showthread.php?t=832545[/urlt

install fresh Android ROM over dual boot hd2

I've set up dual boot to android and WP7 on my HTC HD2. I now wish to go back to only Android on my phone. What are the steps for that. As my SD Card is partitioned will the new android rom be installed on just the NAND portion?

I need to know to what type of filesystem should I format my SD card so that i can install a fresh ROM. DO i need to go back to stock WM6.5 to install this.
[HD2 Android SD Development] despy1989:
Sorry the question is in the wrong forum. This guide is for installing Android on the SD card dual boot to WinMo 6.5

File system for WinMO 6.5 is FAT32

There are different options for the NAND versions and some m=need an ext partition on SD card for system and data loading and some do not. please look in the relevant forum for instructions

Hi guys, thanks a lot for the guide and inputs. Android really rocks in HTC HD2. I have got a question in regard to the update process. If I set for automatic update the update files get downloaded and ask the phone to reboot to complete installation, however the update does not occur since the android is in SD card. Can you please suggest a work around for the android update rather than reinstalling a new ROM?

How long does HSPL take? I bottled out of potentially bricking the phone a couple of days ago but how often does that actually happen?

Do I need HSPL 3 or 4?

Any pointers and reassurance gratefully received.

[HD2 Android SD Development] voncrane:
HSPL takes abt 5 mins..even less...HSPL 3/4 does d trick but its best u use HSPL 4 as its more recent...since u want 2 keep running Android on ur device,then search n read d instructions in HSPL thread carefully 2 know d difference between version 3 & 4...hweva using it is quite straight 4ward..

1. Plug phone via usb and reboot in2 bootloader.

2. Run HSPL 4 (grant admin rights if asked).

3. Follow d prompts & select 2.08 hspl for flashing.

Ofcuz u should ave @least 50% battery left.

What is the different effects of haret, MAGLDR and a bootloader

What is the best way to boot android? Does booting from windows lower memory or speed performance? If so what is the difference between MAGLDER and a bootloader?
[HD2 Android SD Development] voncrane:
Its all a matter of preference...firstly,by using common sense...which do u think would be faster...running android directly of NAND(device memory itself) or running it off a memory card(external memory)..?...Yeah u guessed ryt.

Secondly since it appears u are yet 2 know d difference between MAGLDR & ur Phone's (presumably HD2) bootloader....:eek: ...i was once a noob but i really can't help but conclude since u chose not 2 even try reading d info or following links present in the awesome post done by "despy1989" in page 1 of this THREAD...

Thirdly, there are tons of stickies, HowTo's, Tutorial videos right here on xda-devs...all within a few clicks away...and if in doubt? there's d search function up there...

Finally, should u decide 2 ignore reading adequately before modifying ur device then i beg u 2 either return ur HD2 or send it over 2 me ...then get a "dumbphone" :p

P.S. Besides the post on d first page of this thread, another great place 2 start is here.
[HD2 Android SD Development] rebecker:
Just to understand your comment...you have 3 different builds on your card, with each folder named something like Android, Android2 and Android3 (Android being the current functioning build), correct? In addition folders have been created by the installed apps (backups, data, DCIM, download, TitaniumBackup, etc), correct? In each of the 3 build folders you also have a data.img file, correct? Do the additional folders function with each build? I am currently using 2 different builds on two different cards. It would be GREAT if I could have both builds on one card and have each build access the data in the various app folders.

Thanks in advance.

[HD2 Android SD Development] rebecker:
From the 1st post:

"Upgrading Android Builds

I always do a clean install i.e let the Android build its own data.img with a clean formatted SD card. Once this is done then copy your old backed up data.img and overwrite the newly created data.img to get all your info and settings as they were. "

Should I also copy back all the app folders (excluding the "Android" folder) that were created previously in the older build?

Thanks.

-Bob-
[HD2 Android SD Development] despy1989:
Keep all the folders/files from the newer upgraded build as they are. All you need to do is to then copy + overwrite the data.img file only .

Cheers
[HD2 Android SD Development] despy1989:
That should not be a problem as most apps work with a named folder on the root of the sd card. Changing builds should make no difference

:) just remember that the folders have to be renamed each time thru winmo or thru your pc.
[HD2 Android SD Development] rebecker:
Thanks for your response, but...

Certainly data.img doesn't contain the data that is in the folders OUTSIDE of the "Android" folder, so wouldn't all of the other folders that were on the card also have to be copied back on to the card after formatting? And then the question is, should I run the update without adding my old data.img file once, then shut down, copy all of the folders outside of the Android folder, plus my old data.img file using my PC to the card, eject the card, reinstall it into the phone and run clrcad.exe and haret.exe to restart Android?

Sorry if I sound like an idiot, but I'm just trying to find the best and fastest way to do updates.

Thanks.

[HD2 Android SD Development] despy1989:
Hi Bob

I don't see any problem with ur technique. O am using android on nand now but from memory this is what worked for me.

Back up all folders on sd card to pc using sd card adapter.

Reformat sd card as per ur choice.

Copy back all other folders

From the downloaded build copy Android folder (new) on ur sd card

There should be no data.img / chosen blank data.img in ur new Android folder.

Reboot phone into android

After successful boot shut it down again and copy back ur Old data.img file into the android folder replacing new data.img file

Reboot phone to Android

All settings apps should be there as in the older build

Good luck
[HD2 Android SD Development] coolfire:
I can confirm that this certainly works! Well, at least for the RafDroidHD 4.1 build, which I upgraded doing the exact same thing as above - bootup into new build, letting Droid build its own new data.img, then shutting down, & overwriting this new data.img with the previous data.img of choice. I personally feel that using Titanium is useful only if I wanna retain apps and certain data like smses, emails & contacts.:)

Restarted it and now the tray.app is corrupted (does not work at all) and now I can't install anything on HD2 (I just get the dreaded "not trusted" errors).

[HD2 Android SD Development] despy1989:
No it won't brick your phone as long as you follow the guide. With the SD card android builds you still keep your windows mobile rom. If at any stage you want to go back just choose windows option in the boot loader. You only need to take the windows rom off if you are choosing a NAND version of android.

I also like the look of AmeriCanAndroid but all I get is a black screen and a green HTC logo in fact I got this with 4 out of 7 ROMs I have tried is this normal?

I left it for over 70 mins before rebooting do I need to wait longer?

my question is what android sd rom would be best for my requirements please,

all I wish to do is provide an infrastructure wifi hotspot from my hd2 for my asus transformer to use. this would seem to be impossible from win mo 6.5 as it only provides ad-hoc.

manilla ver 2.5.20181527.0

protcol ver 15.42.50.11u
[HD2 Android SD Development] Yankee802:
If your main concern is being able to turn your HD2 into a WiFi hotspot, then you want this. I can't seem to get either of the data sharing / tethering programs to work in Android (AmeriCanAndroid v5/12/11), so I have to boot into Windows (6.5) to tether.

As far as what version, I love the one I use (previously mentioned). It is the only one I've used, to be honest, so I can't compare, but my mentality is if it works, keep it. Besides, with all the apps out there, these things will do almost anything you want.

Hope this helps.
