[Q] 2nd boot PROBLEM WITH HTC HD2 Android

each time i copy the android on the SD card and i sync it and works great on its first boot, as soon as shut it down then open it through bootloader, it stops at te HTC page of the android, and never starts up the system !
any solution for that,
i have already tried formating the SD card
i have a energy rom GTX
radio 2.15.50.42
and used Mdjeey

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.

i have tried the airplane mode and to get off the battery and insert it again ,
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.

Death of SD/RAM Builds?

Hey everyone, I am glad NAND is finally released (for those that have been waiting for it), but I'm wondering if theres anyone (yes I know the pros of having NAND Android) that prefers being able to dual boot? I'm starting to feel that work will halt on the SD/RAM builds. Any reassurance? Thanks guys.

I'd like to keep SD builds as well.

Naw I think a lot of us non-TMOUS HD2 owners will still use SD builds. Reason being, we just don't have a lot of storage space, which many of us need. Unless Devs perform the ext4 partition thingie onto or sd card, for us to expand storage, storage will still be small for non-TMOUS HD2 NAND users i guess.

Yes, RAM builds are the biggest source of competition for NAND - however, I haven't filled up my storage yet with my apps and still have about 90/100MB left of phone storage.
What about installing apps to SD card???
Signal strength is much better on NAND though for me.

Can you report how many %of the.time without signal with sd and %with nand? I believe you but I didnt test nand roughly because of the memory limitation. But I guess thats gone now

I hope the response will be "No". I use the PSX Emulator (FPSece) on WinMo so I prefer switch on Andoid or on WinMo.

Nand is obviously the next stage of evolution in rom development towards running Android natively on our hd2's.
sd card builds have the great advantage of being swapped easily, especially with multiple sd cards (I have two, one stable daily use which is fully configured and one experimental)
Moreover the risk of bricking your previous device is rather low from sd..
I am not very clear about the difficulty of transferring a build from an sd build to nand and vice versa, but if there could be a migration tutorial, as a sticky we could have both, latest builds in nand and the choice of running them from sd..
Is this technically possible? Which factors could inhibit easy migration?

I thought originally MAGLDR was supposed to be able to multiboot Android and WinMo (probably a non-sense version of each due to space)?

I hope MADLR can do the following soon:
- Load SD\RAM\NAND Android from custom folders on the fly
- Allow backup\restore of the data store
- Load WMP 6.5 and maybe even 7
I think this will keep the flexibility of multiple build loads alive which will benefit the user and the devs. I know some of this should be coming but it would be nice to get all of our belated Christmas wishes.

not sure but,,
im not sure but the aMAGLDR menu does also have the option to boot from SD-card, i havent tried it yet though..
also one thing i still want is the ability to boot my ubuntu-sd-card build, now i cant use haret.exe im not sure how to go about the dual booting thing ??
much stuff to try out
***edit***
ok, just put the contents of an old sd card build directly onto the root of an sd card (ie, without the 'android' folder) booted phone holing power key until magldr menu shows, then select boot AD from SD and it boots just like the old sd card with haret method, -
so far i see it finds zimage and initrd.gz, then i get the boot screen, .... looks like dual booting is still an option even if it may need a bit of tweaking.. i guess its just the startup.txt that needs to be read for it to boot properly ,
*********

I think in the original NAND release thread, Cotulla explains that a SD build (haret.exe) and a NAND build are very different, to use the SD boot option in MAGLDR, you need to put the content of a NAND build on the SD card, somehow...
edit: forum.xda-developers.com/showthread.php?p=10202441#post10202441

I would like it if they could implement a better DFT installer, which had options such as
• Install to NAND
• Install to SD
• Customise partitions
• Multiboot
Instead of just being able to install to NAND. This way, we can have a single installer / release for both methods (and this would make it easier for chefs )

I think it's impossible to say for how long - but on Darkstone 1.5 RAM, and MDJ's HD4.6 I would find the signal to have disappeared at least once a day up to three times - requiring a reboot of the phone - airplane mode did not seem to work.
After reboot signal would return to full strength in the same exact spot.
Problem is the signal would be lost in a pocket or on my desk and you simply would not notice it until you went to use the device - in fact the first time I realised it was happening was because I was getting far fewer emails/smses and calls and the phone was utterly quiet - very peculiar for the holiday season and party planning.

I haven't as yet downloaded a NAND build although i may well do that this evening, however having downloading many different builds for Android over the last few months i can safely say Dark Stone's SUPERAM blows everything out of the water in terms of speed it really is very fast which IMO is very important.

[Request]Dual boot WP7/Android NAND and Android SD (Only one working SD rom)

I'm making this thread here because I can't see anything being done to remedy this problem.
I have tried more than 5 roms that I have used in the past in SD era with MAGLDR 1.12 in the option "AD SD" and none worked. This SHOULD be easy, but it's not.
I have tried to change kernels for the new ones, thinking this would be the right way to do so, since the old ones expected haret and windows to work. This didn't work too.
To name a few...
NexusHD2-FRG83D V1.8 from Tytung (the best in the old days for a clean froyo, IMHO)
MDJ Desire HD 4.6
Topia HD and others...
None of them worked, the ONLY ONE that worked was [DL DesireZ v2.1][SD/NAND] (note, not tested version 2.2, ONLY 2.1)
It took a looong time to boot, but worked fine.
Now that we have WP7 (not everyone will want this permanently) we should have SD roms that are compatible with MAGLDR. Even because MAGLDR is way faster than waiting for WM 6.5 to boot.
I loved WM 6.5 in the days, but now, several of us don't want to deal with it anymore, and are just here for the two new OSs.
I would like to see some development in the SD ROMs again, so they can have newer and better kernels (the ones used with MAGLDR) and full compatibility with future development for MAGLDR and NAND.
We could even have two Android builds, for those who don't want WP7.
One for NAND and one for SD, like a Gingerbread and a stabler Froyo
Anyone agree with it?
Greetings, Santroph.

Problem:
Phone7 formats the sd card in an unknown file format.
That makes it presumably impossible to linux to load from there...
You would have to switch sd card

I agree with the suggestion of having dual boot (WP7/Android), in fact I even thought about it yesterday ...
What about having 3 partitions on SD ? 2 for WP7 and 1 for Android ...

Yeah I know about this, but several of us, myself included have several SD cards.
I can pass for the trouble of changing SD cards from time to time to boot a completly different OS, with several other possibilities.
And I was talking about Android NAND / Android SD combinations as well.
Like I said we could have a Gingerbread experimental in nand, but keep a really stable Froyo in SD as our main build, or the other way around, a lot of us have big enough cards to do that.
Santroph.

I'm tested lot android SD too.
PSfreedom worked only but if the DL DesireZ v2.1 is working..what's the problem?

The problem is that we only have a few SD roms working. And for example DL DesireZ v2.1 works, but DL DesireZ v2.2, which is newer and just lauched, doesn't work, the support is gone
And we don't have as much roms as we had to choose in the past. I am trying to use WP7, to see if it is a viable alternative to my daily use, but I don't want to give up Android. Since we can't have WP7 and AD Nand at the same time, SD is the only alternative, and we have to get whatever is working instead of a lot of good builds like we have in Nand now.
If the devs start to make more sd builds closer to the Nand ones (same kernels and modules, which they can do now, since they will all be using the same hardware startup MAGLDR) we would have a lot of alternatives too.
Like I said, one of the best roms we ever had, tytung NexusHD2 froyo, doesn't work.
Santroph.
P.S: I'm willing to help any dev that need help. I'm a developer too, but a software one, not a cooker

I'm not a dev but I try to get it ...I took 4GB sd and booted wp7, connect sd via usb reader to pc, copied the wp7 filesystem to my 16gb sd card...wp7 says I got 3.5GB disk space ^^...means: wp7 uses 3.5GB, 11,5GB free sd space . formatted other partition as fat32, but windows7 didn't find it. Now I'm trying around to get it working ...will post news
EDIT: WP7 got 3.5GB disk space, now booting MDJ Froyo HD 4.6 from sd card ...So I got WP7/ Android dualboot

I succeed to flash WP7 rom without SD card inserted. Inserting back the SD card after installation shows that SD storge with full size(not under WP7) and SD android rom (DL DesireZ v2.1) works fine with MAGLDR 1.12. Booting WP7 again will not destroy it, too. This may be a temporary method, while the free space left in WP7 becomes around 130MB which may not satisfy many demands .

was the WM7 functional?

Can you please make a kind of Tutorial?
I understood what you said, and I can probably replicate it (surely will try) but some people would be really glad to have a tutorial.
I have a single problem with your approach, my biggest card, the 16gb one, was the one used for WP7, so I will have to reformat, and since I already got my WP7 working with marketplace and activated, I don't want to mess with it.
If I only had used the 8gb or 2gb card, I would be able to do it....
Santroph.

The best way to know how to do this, would be to have a HD2 that has not a fully working copy of WP7, so we can test it as much as we can.
The biggest problem for me now, is that I don't have how to make a backup of my WP7 installation, or else I would do it and make a tutorial on how to use the dual boot.
Even with the option of using only one card, the SD rom version must be compatible, which in the present time, they are not (most of them).
Santroph.

i've readed all of thread.. but yet i don't understand if it works or not.. especially with ike2903 tutorial to format SD card method...

Noob. Need Help Starting OVER From Scratch

After 2-3 weeks of using Android on my HD2, I'm totally sold! However, I installed Android on a card that also had lots of WinMo stuff on it. I would now like to start over from scratch on a totally clean 16GB card. I would like some info, however, before I start.
1. I have purchased several apps from the App Store. Should I uninstall them from my current SD card? My concern is that the store will not allow a second install to the new SD card.
2. Should I reformat the new card using the WinMo operating system or the formatting capability of my Vista laptop?
Any additional suggestions will be greatly appreciated. BTW, I'm intending to try darkstone SuperRAM FroYo v1.5 [kernel: Hastarin custom] first. Depending on how that goes, I may try MDJ FroYo HD v.4.6=-[FRG83D][kernel:MDJ S8.0]. I am currently running MDJ_FroYo_HD_v._4.4_MDJ_S7.6HD.
Thanks.

No need to worry about the store, the Windows Mobile Marketplace is tied to your Windows Live account, so when you switch back to Windows Mobile 6.5, or Windows Phone 7, they will already be outdated and useless anyways because WinMO6.5 will feel like crap, and some programs in WinMO6.5 won't work in WP7.
Backup whatever you think you will need on the SD Card.
I recommend refreshing the MicroSD card with SD Card Formatter 3
However, in Options, Format type = FULL (Erase ON), and Format Size Adjustment = ON.
This will wipe everything off from the MicroSD Card.
NAND Androids are pretty good so far, so if you are going that way, read up on MAGLDR and how to install. You will need HSPL 2.08 and RADIO 2.15.50.14
You will also want to read up on Clockwork Recovery.

Sorry, I was unclear. I was talking about the paid apps I installed from the Android Market. Should I uninstall them from my current Android installation before starting over?
Are you recommending AGAINST SD Android versions? That's what I've used so far and am pretty impressed. I also like to have the security of staying away from ROM installs (I have a European HD2, so I'm not sure about the memory issues). Plus, I've read that darkstone's SuperRAM FroYo v1.5 is the fastest HD2 Android version available. Speed would be my only criticism of Android on the HD2 so far.
Thanks for your response.

I think your answer is meant for NAND but if I understand correctly then the mentioned new ROM are SD card / RAM builds
My suggestion
1) for Dark stone build is to start from scratch. If you want to restore all your apps etc then the best option is to use Titanium Backup and then you can restore all your apps +/- settings. For Contacts / Calendar Google account sync is the best option
2) if you are going for MDJ 4.6 build then just copy your data.img from the 4.4 build and place it in the downloaded 4.6 build folder and you are all done. all your apps, data, settings etc will be as before...
Before you do anything make a backup of your important files in the SD card and the data.img file from the old 4.4 build ...very imp. Once formatted you can copy the file back into the SD card
For Formatting you are better off using the default format option in windows PC as it allows a better slower format and you can specify the cluster size (32 /64 kb). For me the SD formatter 3 program did not work and kept giving errors.
As for SD card ROM i think they are great but unlikely to develop further due to stagnation.
The RAM build has problems with using HTC SENSE base (as its too big for the RAM space avail) and i found them to be a little unstable with likely hood of data corruption which is easy to addresss if you keep a backup of data.img on your PC.
At the moment NAND is developing fast and with usable and stable HD desire builds available now , but is a little complicated to set up at first. However if it all goes wrong...it is definitely possible to go back to Win Mo and start all over as before. You should try both if possible and then go for the one you like.
My only probs with the SD build was of speed of bootup which was at 3 min, slight lag in the build and occcasional wakeup lag / SoD and i found it difficult..otherwise no complaints.

Which NAND version do you recommend? I'm looking for speed and simplicity. And I have the European (English) HD2. Isn't there an issue with memory?
If all fails with the Nand install can I just run the WinMo ROM I currently have installed from my PC?
Thanks for your response.

Windows Phone 7 from SD card or Android/ WP7 Hybrid ROM?

I was wondering if it would be possible to either Boot Windows Phone 7 through MAGLDR from the SD Card like you can Android by maybe partitioning the SD Card so it cn have it's own space?
Or a more realistic option which would be to have a NAND ROM that includes both Android and WP7 installed to the NAND and partition the SD card for storage? This second option I believe could be possible if the NAND is partitioned correctly to allow them both to run and then you could select them in the MAGLDR!
I would like some dev feedback on this as I would try building a ROM myself but I don't know the workings of the partitioning system in MAGLDR well enough to try!
Thanks in Advance for any help!

I've seen that but what I want is to boot Android and WP7 from NAND NOT run android from the SD Card like that guy done because that makes android run slow and I want android as my primary OS!

I run Android from SD as my primairy OS, WP7 is on NAND just to play with and test it. I tried Android on NAND, but to me it wasn't noticably faster then when running from SD.

Snap I'm using sd build of Android from magldr and it runs fine even boots ok, there might be a little lag when doing something the first time but other than that its great

Well the thing is I like to use a fully fledged Desire HD ROM and it's stupidly slow from the SD card... my current build is squashfs'd so only takes up about 200mb for the actual OS and I'm sure WP7 could be fitted in the rest of the space and like I'm doing now I can use EXT4 on the sd for data! Now what's needed is if someone can build a hybrid ROM!

Hi, anyone can share how to u do this ? is it through the method that uses 2 sd cards during the formatting stage ?
Btw, what if i dont mind swapping sd cards for diff os ? Can this be done and how ? I tried to insert another sd card which I previously use for my android sd build, tried the sd boot , it gave an error of sd kernel . anyone can advise ?
Thanks !!
