i am using MDjeey froyo HD v.3.7
tried your idea now ,, didnt work.

I've had the same problem with the latest roms released this week, so I'm assuming it MIGHT have to do with th kernel that they have in common). When it gets stuck on 2nd boot, I simply pull out battery and try again. From then on I don't have this problem anymore each time I boot using clrcad and haret. I'm not bothered to change kernel and the latest seems to be best, thanks to the dev's hard work.

click on Clrcad and haret ,, still stuck on the HTC page ... gosh its annoying

Have you tried another build? I am on revolution 1.7 with s7.1 kernel, I have the second boot issue, I just pull battery out, reboot and there I am, no more issues.
You can't boot HD so try revolution.
I also use exceller to autoboot under 3 seconds.

thank you , i shall try that again,, do you have a link to 1.7 revolution ?

Are you using one of those Class 6 or Class 4 MicroSDHC cards?
If so, replace it with a Class 2 Sandisk or a Class 2 Kingston MicroSDHC card.
In order to achieve Class 6 or higher standards for MicroSDHC cards, some manufacturers uses tweaking, which saves cost in making a "real" class 6 media card. These tweaks causes different problems in different devices. Tweaks may include increasing sequential read speed, but will cause random reads/writes to not be stable.
Which is probably a reason why Microsoft Phone 7 won't allow you to use your own MicroSDHC except the one they approve, and they are still working on the list.

do you mean the Temp android folder created after the booting ?

so far i tried the 1.7 revolution and i tried to reboot it once , and it worked gonna give it a go for a couple of days and feed you back
many thanks all for your help

You can also try the following:
1. Download the Android build once again
2. Backup your SD card to your desktop PC
3. Delete the Android folder from the backup just made
4. Reformat your SD card
5. Restore your backup to the SD card
6. Extract your Android build to the SD card
7. Boot Android

had the same Problems with the older kernel and the newest radio..using mdeejay, too.
I changed the radio to 2.12.50.02_2 and set up the newest hastarin kernel together with the titanium Energy Rom and now it works out perfektly

@ OP, this should be in the general section.

I had same problem before. Try to run a check disk thru windows under the removable drive tools. Also have it check for bad sectors.

[Q] Android wont boot on SDHC card?

Hello all, first post here.
I just bought an HD2 from eBay and it's in immaculate condition. I checked the HSPL and it was 1.66 Cotulla. Along with the phone came a 2GB SD card, to which I put darkstones FroyoStone 2.2 with Sense; and it has been working perfectly with no issues (except battery lasts about 12 hours with average usage).
However I want to install and test other builds on my 8GB SDHC which I have lying around. I have formatted this many times to GUID/MacFS, ext3 and FAT32 over it's lifespan.
When I tried to boot Android on my Omnia i900, I had an error with the SD Card and it never loaded; now when I boot the same or different Android ROMs on the HD2, they never boot. Even the exact ROM I have working on a 2GB SD card that I am using as a daily is not working on this card.
Could anybody help me with this issue?
sounds like the sdcard may have died from all the formats/flash's...
do you have a partition manager program etc that can check the card its self? most linex based partition programs will tell you if you have dead blocks.
personaly if im takeing a card thats had all sorts of partitions thrown at it, i format it, wipe it, then do a 0 wipe, this usualy fix's it.
Can I do this using the OSX Disk Utility to 'Zero Out' all the data or should I boot into Ubuntu and somehow get gParted working?
Thanks
i have no experiance with osx, but yes, gparted will usualy do the trick.
disk utility worked, thanks for the help. saves me buying a new card
good to hear! its amazing how much faster things run on a clean card...
format people!
I have question that goes with this one....I am running core series V4.1 it has the andriod boot on the windows side and I used one andriod build in this mode , but when I try others it seems it does want to go? What could be the issue?
Seems I just booted up Evo Core series on my phone, WOW i may never back to windows

Did you format, within phone, to FAT32? It looks as though you have experience with builds so I'm sure that you are installing the Android folder on the root of the SD card...make sure that you don't create a folder and then add the build folder to the root folder; it creates a sub and that causes problems.

No build start. i waitted 2 hour's for data.img to be created but no succes. i tried with version copy pasted from my old card who works, still nothing. i don't know what else to do .

It might be as simple as the "Serioux" card isn't supported; the only other thing that I know off the top of my head is at the bottom of my thread; I had found a link to the formatting issue and that's where I came up with the idea of formatting within WinMo.

I know that it does take some builds to load as it creates the data.img, especially a larger one; if you opted for the 1gb for instance.
You are using the same build as the other card? And, you loaded the file the same way? Did you do it through USB connect?
Let's see if we can't get this goin'!

I think it might be the card. I know that I've seen class 2 and 4 around working; your "Serioux" card is the only one that I can find, as far as brand, and nothing about it working or not working on HD2, maybe return it and get another brand?
It's definately the card. I bought a wintec class 10 16gb and android wont run hardley at all on it, went and bought a 16gb sandisk class 2 at radioshack and android runs flawless on it. The shame is that the sandisk class 2 tests at class 10 speeds. They have it on Newegg for $34, Get model # SDSDQ-016G-A11M. There are two versions on newegg so make sure you order the right one. You won't be disappointed.
thank u all for support. i will try to get another brand. in this time maybe android will boot from nand

[Q] HD2 Not booting up and tried 12 diff roms

Everytime.. I format my sd, download a build, extraxt to desktop, mount to root of sd, run clrcad and haret, And all i get is a 'jumping to kernal (custom) and freezes or just a frozen htc screen.or a boot loop.. I am running a energy rom for windows someone plz help
Ok by 'mount to root of sd', do you mean that you're putting the Android folder at the root of your sd, or you are taking everything that's inside the Android folder to the root of your sd?
The folder itsself goes to the root of your sd card, with all the files such as zImage, Haret, etc. inside of it.
Other than that, are you using a launcher like Exceller's or anything, or are you launching by tapping CLRCAD and Haret in your file explorer?
Try it from file explorer til you get the build up and running a good couple of times.
Is your radio a XXX.XX.50.XXX radio, or is it a XXX.XX.51 ?
You need a 50. (2.08 and up) To check, boot your phone up and look at the little red info down in the corner as it boots up. The radio is next to the 'R'
If you already have all these things correct, I would say to try a new sd card.
Hope this helps, good luck
You have to flash a working radio version first

Format your SD card in WinMo by the way, seems to be more effectice.
What radio do you have? It's the most obvious thing that would cause this problem and you haven't told us yet.
thanks for help everyone turns out my sd card was messed up from all the formatting i guess... Bought a new sd and im back in business.. Life sucked without android **** windows mobile lol

[Q] Compatible/Recommended SDHC cards?

Hello everyone, I would have posted this under:
http://forum.xda-developers.com/showthread.php?t=881937
but my less then 10 post restriction is not allowing me to .
My problem is once the ROM boots up, as soon as it says "Preparing SD Card", my phone freezes. The only thing I can think of is that I have an incompatible SD card. I am currently using the one that came with my phone which is a class 2 16gb SanDisk. What would you guys recommend that I use?
Use a program called SDFormatter (from Panasonic) .. format it.
Then use windows format utility to give it a slow format 4096 cluster FAT32
Works great for me on "broken" cards.
He's right. The stock card should work.

A class 2 Sandisk should be fine unless it's defective. Maybe you have build setup wrong... have you tried a different build? Try that and see if it works. Are you trying to dualboot or anything like that? Or load the build with magldr?

Possibly and no I haven't tried a different build yet but I will if this continues to happen. I am not dual booting at this moment but I am using magldr to boot up android.

If you are using magldr, you need a build compatible with magldr or edit the init.rc file in the build to make it work with magldr. Look at the thread in my signature... post 2 has some builds that I edited to work with magldr. I'll be adding more soon.
Alright, well I've formatted my sd card and now it's worse then before. It just stays stuck at the MAGDLR screen and doesn't boot up at all. As far as I know the build is compatible with MAGDLR so I'm not sure what the problem is.

Android on SD Card + Original ROM

Hi there
So I'm reading for a while the topics about android on SD Card, but I couldn't fix some issues and I hope you'll get me out:
1) Can I use the original ROM from my HD2 and install Android on a SD Card
2) Is there a possibility to install Android on the SD Card and get a boot loader where I can choose between a WinMo boot and an Android boot or do I have to boot always WinMo 6.5 before booting Android?
3) I read that the speed with the SD Card Mode is slower than the other ways, how can I understand that? Do I have to wait longer during the boot of android or are there also speed problems while working with android?
4) Also on the speed problem: Which SD Card would you recommend for Android on SD? Are there any measurable speed differences between the CD Classes?
best regards

Yes you can install android on SD and use WM6.5. Its what most of us did back when you couldn't NAND boot android. There are several bootloaders around yes, however you always have to boot into windows in order to boot SD android. This means android SD boot time is much much longer than NAND, however this is not really that big of a problem. As with the speed problems with the ROM itself, well lets just say i much rather prefer NAND to SD, I used SD for a long time and NAND was something that made me very happy. I didnt really see a problem with SD builds however I simply felt more secure using NAND. Also, with an SD build the speed of the phone is dependent on your SD card class, most SD cards are class 2, mine is class 6 and my SD build worked fine however I have seen people saying its slower with a lower class card. I don't know whether its actually a real issue, like you need a class 4 card to run android properly however people sometimes complain. This however could simply be their ROM's/Phones being slow.
Does this version (FEB 14)[SD]MCCM HD V4.0 [DESIRE HD Sense] Perfect [kernel gauner1986's] work at anyobody with the original ROM ( 3.14.207.1 ) and 2.15.50.14 Radio ?
My actual version is the
[Dec 18][RAM] darkstone SuperRAM FroYo v1.5 [kernel: Hastarin custom]
and it works.
The installation of the MCCM is exactly the same but it doesn't work.
When my device reboots there is the HTC logo on a white background and i have waited for an hour but nothing happend.

Sounds good. So what I don't understand: Booting Android from SD Card - does WinMo Shutdown or does it still run in the background? So is the full capacity of the CPU & RAM available or not?
I think a Class 6 16GB should be enough for that game. I actually like my original ROM and would like to try android just for fun, so I think the NAND Method wouldn’t be that, what I’m looking for.
Do I have to buy a card reader for my SD Card?
Any other experiences with Android on a SD Card?

My opinion about Android on a SD card is very positive.
My version is very stable.
Until now I hadn't problems with any bugs.
The browser is very fast, the camera good, the connection to WiFi is perfect and all games work
But it's clear that you have to charge your mobile often

SD android also has a high battery drain, I dont know the exact figures but i think in standby sd builds are 5-10mA, where most NAND builds are 2-5. You wouldn't NEED to get a card reader, however it would be an extreme help. SD android is very good, however NAND is better for me because personally, android blows the socks off WM6.5, so I just decided to go all out. SD android runs on top of WM6.5 yes, however WM6.5 is shut down so you do get the full power of ram/cpu etc.
I love SD, partly because I love my build (Black&Blue Remix), and have been rock-solid on it since November. I keep trying other SD Builds, as well as NAND builds, but I'm so hapyp with my set-up I have no desire to change, at least until builds with updated Sense/GingerBread/Honeycomb come out
I've got the Extended Battery pack so maybe that sways my judgement.
But I have no qualms in recommending SD!

To make this part clear: I can only download a Android ROM, put it on my SD Card, insert it in my HD2 and here we go? HSPL is only needed when I'm trying to flash android?

So the question to you is:
What do you understand under high battery drain? I recharge my phone every night, not depending if it's empty or not (does this have an influence on battery life btw?), so... does the battery last for 2-3 hours of surfing, emails ... on sd android ?
