Questions Re: Android and Win Mo?

Gday all im a bit lost in the android forums so im just going to do a noob thing and ask for some assistance, thanks.
I just installed the "[30 DEC][DFT]LEO "Stock Desire" NAND Android ROM" rom over top of my last rom from WINMO, which was the Energy jan 6 rom.
I also installed the latest Radio "Radio_Leo_2.15.50.14" and HSPL3 along with "MAGLDR112" everything went sweet upon install, so i have no real questions regarding that but im wondering how i can boot back into WINMO if its possible?
If i reboot the phone it just auto loads into Android.
Also i would like to know what the best Android rom is for reliability and secondly how would i update the roms as new version are released?
I think thats about it for now, the rom in currently using feels smooth and great the apps work fine but it feels a little locked down compared to the WINMO but it hasnt crashed on me in the past day which WINMO would have by now, lol.
To flash back winmo, simply go into bootloader/tri color screen. This is done by holding vol down, then powering up.
I'm not going to answer which is the "best" android rom, as that has been asked many times, where there are many answers for, so, search it up.
Updating differs. If it uses daf.exe/install.exe, it's that same as how you flashed android for the first time, however sometimes you can't retain your settings. Clockwork mod flashing however, is unbeknown to me, haven't tried it yet, sorry.
Thanks for that, so what would i need to do to backup my settings and info on the Android just incase i reinstall it just say?
Also if i back to the bootloader would that mean ill have to reinstall a winmo rom?
Then if so would it only boot into WINMO and not android?
Secondly how would i be able to reboot into android again?
I guess im asking is there a way to dual boot and whats the best way about doing it?

r u being jackass?u have to flash stock wm rom first.ok then u can flash any custom rom.
ok use titenium backup to backup ur android settings abd appp..
ok and after winmo if u want dual boot u have to install sd android build to ur sd card
Why would i want to be a jackass?
Yeah i come on here to troll these forums to post noob questions for ****s and giggles, are you such a person who angers over someone who clearly doesnt know what he is doing and yet you think im being a jackass (god i hate that word, lol never used down here though).
I hope i clearly posted im the OP on how and what i installed but now im lost, i have android working fine but i dont know how to back any data up just incase i do an update or even flash back to stock rom and maybe come back to android later and hope to reuse the backed up data from the android rom.
It took me about a year to get used to WINMO and learning how to install a custom rom on it but now i thought i give android a go and i managed to follow the steps without any issues (yes there were a few more steps i needed to do than i did need to do for a custom rom for WINMO) but now that i have it running i just want to know what to do to get WINMO back on and preferably getting WINMO and android working side by side.
I know how to flash custom roms in WINMO but im just wondering if there was a way for me to be able to boot back into winmo while i have android installed, all i want is to be pointed into the right direction or shown a link to a walkthrough or just given a point form reply as to the process on what and what not ill be able to keep and the best way in doing so.
So from your reply i gather ill need to install android to my SDcard and not the phone memory in order to run WINMO and Android together am i correct?
If so then because i use the ENERGY ROMS i can boot to android from within the ENERGY ROM, am i correct? i think NRG did something with android in his roms.
I am really sorry if i have upset anyone (above) but i am really lost with this, yes i pretty much understood custom roms in WINMO but with this i just did it spontaneously VERY VERY late last night and i wasnt thinking straight i just gave it a shot, so i put myself in the deep end and now im very confused with getting it back to normal as such thats all.
Worst case would i just be able to reformat the SD and then boot to 4 colour screen and just do my custom WINMO install as per usual or would i have to install the stock rom back then install the custom rom?
First of all, ignore the "jackass" above. That was just plain rude and he made himself look like a total idiot.
Secondly, if you want to backup your current Android setup, get Titanium Backup from the market. There's a batch job (click menu, batch jobs) that backs up all your apps & data and system settings. It backs it up to your SD card though, so be aware of that if you're thinking of formatting it for any reason.
Next, get the WM6.5 ROM that you want to flash (doesn't have to be a stock one). Enter the bootloader (tri-colour screen) and flash your WM ROM as normal.
Finally, when you flash a ROM onto your phone, that becomes the only OS on there. You can't switch between Android NAND and WM without flashing. You can, however, run Android from your SD card. There's a forum dedicated to that here...
HD2 Android SD Development
There's lots of info in there on how to do it, but it's basically unzip a file, copy the contents to your SD card, run 2 apps. You'll probably want to go down the route of a bootloader (not really) that runs in Windows. It lets you select Windows or Android when you reboot. They too can be found in that same forum.
That's the only way you can switch between Windows and Android on a regular basis, without flashing a new ROM.
Hope this helps
Thank you very much it has cleared allot up for me, now i know that because i flashed android on the phone its the only OS i can use, i didnt know that TBH.
So yes thanks again and ill do it the SD way and try my luck with that.
One more small thing, how do i go with updating the current android rom im using (if it were to be updated), does it work in a similar process as WINMO custom roms and their updates?
Again i much appreciate the reply, it has helped already.

Generally, you flash an updated ROM the same way you flash the original ROM. There are backup options like Titanium Backup or ClockWork Mod (if the ROM supports it), so you can get everything back up and running again.

[Q] HTC HD2 freezing when it boots up

Whats up everyone, quick help here. I got a hd2 from someone and they tried to flash the phone to dual boot android on it. The guy was unsuccessful in doing so as a result the phone now freezes when it boots up and i would have to take out the battery to turn it off.
Do I have to flash the phone back to the original windows 6.5 rom to resolve this?
any help is appreciated
Depends on what you finally want to have on that device.
If you want to go back to WinMo 6.5 as major OS, it certainly is the easiest way just to flash a stock ROM.
If you still want to continue with a NAND Android build, maybe it´s enough to check the versions of SPL, Radio ROM, and MAGLDR - as well as the Android ROM that was flashed. Could have been a bad flash after all.
But since your data is extremely meager, no way to give a generic and easy hint.
thanks for the incite..first i want to get it bak to factory settings so i will want to flash it back to the original rom.then ill look into flashing it myself with the droid rom without windows..no dual boot.
do you have a link i can follow to flash it back to the original windows rom?
same problem Please help
Hello there I was the same problem with my HTC, I can't flash it back to the original rom. It's just frozen at the boot loader... What should I do? It's not recognize on my pc...
what do you mean frozen at the bootloader? it won't recognize if you plug in usb at all?

[Q] HELP: New phone

Hello all. I just got a HTC HD2 from a friend. It has Windows running on it and then he put android 2.2. Well had gave it to me today and said that when he wiped the info on it today for some reason it wiped the bootloader and now instead of asking which OS I want to run when I start the phone it goes straight to Window. From there I have to manually go to the SDCard and launch it.
How do I fix this issue?
I want to put the Android OS on the Phone rather than the SDCard, is there a simple way to do this at the same time?
And I want to put a new rom anyways on the phone at some point. I rather have Gingerbread running on it, would there be an option to fix this all at once?
I understand the phone to a degree and how it works but rather new to how to do all this at once or in the right order, and what to look for.
ANY HELP WOULD BE AMAZING!!! I need to get this phone up and running by the end of the day. Thanks again.

How do I put the bootloader on my phone so it will auto go to android?
Or should I just do the "Flashing Your First HD2 NAND Android Rom"? I am assuming that this will redo everything my friend did and also put it on my NAND? And it will be the latest version?
I need more feedback guys, I don't want to brick the phone, in what order should I proceed?

Hey just click on my guide I have in my sig and read it as it will let you now more about the tools you need to flash a NAND Android ROM. I also have that guide that was linked for you linked at the top of my guide and another very good guide to installing Android to NAND that is posted at the top of the Portal as I gues you would call it a stickie for now as it has been there ever sense Gunjahman wrote it.
Also if you want to stay with a SD card Android build then check out this dual boot app.

[Q] How to delete NAND android?

Hello everyone,
I bought an HTC HD2 a few days ago, (not a new one) And it was installed with UltimateDroid, I don't really like this version, and Sense doesn't work on it, so I was wondering if I can delete it, and how.
And if I delete it, Will my phone automatically run Windows mobile?
I'm new to this and this is my first time with android and htc, So I don't know anything about it.
Hope someone can help..
You have to flash a new rom using AD Recovery Tool
Easiest thing for you to do would be to start from scratch or follow this guide. You shouldn't need to do step 1 and you will already have the prerequisites. This is for Android, not WinMo.
For WinMo, download a ROM and flash it from bootloader. See the Windows Mobile dev stickies for detailed instructions (you will be able to ignore the HSPL part.)

What do you want in stead of UltimateDroid?
Android with sense, or WM6.5?
We need to know this in order to give you proper help.
I personally recommend Android, WM6.5 is a dying OS...

Dual boot is possible, WinMo on NAND, Android from SD, you can even have Ubuntu Linux on SD at the same time for triple boot.
To wipe data if you plan on going back to Windows Mobile on NAND, just flash a Windows Mobile ROM at the tri-color bootloader screen (boot the device up while holding the vol - key)
If you have Android on NAND, and want to keep Android but just want to wipe data, there's an option for that in CWM Recovery.
If you have WinMo on NAND, and just want to do a data wipe/factory reset, power on while holding both volume keys and follow the on-screen prompt
If you want to format your NAND memory, there is a tool called task 29, but it's not necessary.
If you're asking whether you can run both Windows Mobile and Android from NAND, no. It's one or the other

Sorry for the late reply, I want Android with sense! I have no experience with flashing roms etc. Never done anything like it before.
OK really first do you have magLDR or cLK ... when you turn on phone does it immediately go to boot screen or do you see some running script followed by 1,2,3,4,5,6 ... go go go!
if you have go go go the simply go to the Dev forums find a rom with (magLDR) in the title and follow instructions. they almost have a link to the best recovery to use with their rom.
if you boot straight up like a native android, or you can charge your phone when its turned off you have cLK ... to the dev forums and look for (cLK) in title and again follow instructions and get to it.

It says the 1,2,3,4,5,6.. go go go! thing, but I can also choose to go to boot screen, which gives me all kinds of numbers with flash rom and stuff.
But thanks, I'll have a look!

[Q] Hd2-messed up screen

Hello mates, i have a hd2 with nandroid installed. Last week my phone's screen totally messed up, i can't even see the clock, it has vertical lines all over the screen. It still has warranty but as you know changing rom makes the phone go out of warranty. My question is, if i change my phone to the stock rom and install wimo 6.5, is it possible for the firm that i'll give for warranty to not recognize it? I mean if i do it, will they fix my phone under warranty conditions (without money of course)? Thanks in advance...
Ps: By the way, how can i change to winmo? I can only see a vertical row -this means nothing- on the screen.
In fact, putting back winmo will solve the warranty problem.
To install it, just restart in butloader holding volume down while switching one. Then flash.
sent from my HD2 using XDA App
So anyone can help about rolling back to winmo? tutorials or etc? thanks...
Your going to have to flash via correct WM ROM image from SD card.
Find a link for your ROM (correct country & provider as required) or hopefully you have a ROM image saved prior to Android migration.
For flashing from SD do a search as loads of tutorials on it. You could also do it via USB but you will have to remember to change HSPL as this will remain after ROM flash via USB flash method.
If goes smoothly you will be ok, if gets errors you could get stuck if unable to read screan info !
[/COLOR]To roll back to windows mobile, go through this thread and refer point no. 5. Goodluck.
