Hi, as you can see in the name of the topic ,now I'm using wm6.5 +android ICS nativesd with Sandisk microSd 8gb class 2 and I want to flash windows phone 7.8 but with another microSD card Sandisk 16gb class 4 and again to dual boot with android nativesd. And my question is should I make a hard reset to windows mobile 6.5 before I start to flash windows phone 7.8 and should I format the new SD card before using it for flashing the ROM?

no need to hard reset WM6.5 and no need to format card if already fat32 (you can but not necessary)... during flashing WP7 all be erased (WM and SD card)

Ummm flash back to stock rom 6.5 and then flash Android - unless wm7 is stuck once installed...
this should help ...

Thanks for the reply.
Can I just boot into MAGDLR and then USB flash NAND build as per normal? Do I need to do anything special with the memory card (i know windows phone 7 does weird stuff to it and dont want to nuke it...)
Cheers
I think you have to reformat your SD card, as WP7 makes your SD unusable untill you have formated it

Ok cheers
How do I do thins? When I connect the windows 7 hd2 to the pc it doesn't see the memory card.
When i flash to android, will i then be able to see the memory card and reformat as normal?
Also as above, am I ok to just reflash via MAGLDR straight from windows 7 to Android NAND? Or do I need to flash back to stock wm6.5 and then reflash to Android NAND?

Put sd card into card reader on pc and format it there. You can use Panasonic SD Formatter (search xda for it)
You should be fine to flash to Android from WP7, I did this but to be safe I also ran a Task29 first.

Either that or put it in an SD card extender and put that inside a digital camera. Then do a "low level format". That would do it.
hmm whats a task29?
Im begining to think it may be easier to flash back to wm6.5 then flash to NAND Android
Task29 formats the NAND area where the roms are flashed to, so you start with a clean base. You can use this tool the do it and it is so simple (much easier than flashing to a stock rom again and then hspl and radio etc etc IMHO). Just be aware that as Task29 formats the rom when the phone reboots there is no rom to boot into, but just boot into bootloader and then flash magldr and then your Android rom.
Either way though you will still need to reformat the sd card after running WP7.
OK
So I flashed a NAND Android ROM, all went well and boots fine. The computer can now see the 16gb memory card in the HD2 but says its only 200mb (I think windows 7 must have used the rest)
When I format it in Windows (whilst its still in the phone - i dont have a card reader), it doesnt free anymore space than the 200mb.
Any thoughts how i can get the remained 15gb back?

You can format it using a digital camera if you have one that takes sd cards (put the micro sd into the sd card adaptor). If you don't have one then you will need to get yourself a card reader in order to format the card.
Or you could use a partitioning program, delete the 15gb unknown partition and then create a fat32 partition.
Hi,
I have a question which need some advise. I am currently dual booting wp7 and android sd build. I use magldr to select boot from sd whenever i wanna use android. Btw, I swap btw 2 sd cards, 8gb each , one for wp7 and one for android.
I happened to find a spare sd card 8gb class 4 and thought would like to replace the android sd card which is only class 2, in hope of faster speed. I copied all the files from old sd card to the new class 4 and tries to boot via magldr as usual. However, i encounter this error which says kernel sd fails and thus cant boot. I insert old card back and it boots as normal.
So my question is does magldr recognises the new sd card and thus do not allow me to boot with the new sd card? Anyone knows and can advise ? Thanks
Btw, using mdj hd4.6 w/ wp7. 2.25 radio and magldr 1.12. thanks !!!

Windows phone locks the sd card.

Search Google installing windows 7 on nand hd2 and android on sd. You must create 2 special partitions.
Or check if you didn't encrypt the card in WM by accident
Hi;
I use WP7 on my HTC HD2.
Also I use SD Android and i start android from magldr.
When i want to install SD android on my "HP 16 GB Class 10 micro SD card" , i have installing problem.
While installing it freezes. I can't finish installing.
I don't see main screen.
But when i install same android rom on 2 GB micro SD card , there isn't any installing problem.
It runs perfectly.
Why does this problem occur on 16 GB Class 10 HP micro SD card?
Thanks a lot...
first of all this should be in the Q&A section.
is your SD card formatted to run dual boot? was the 2nd partition for Android set to Primary? also you don't install SD ROM, you just copy it to your SD & set magldr to run AD from SD

If you are dual booting you should have two partions.The android partions should be fat32 32kb cluster size and both partions should be set to primary.

I going to grab sandisk class10 uhs1 . Is that would make my android perform good as well ?
hi, anyone using a 32GB Transcend card?
win 7 was ok with a 2GB Sandisk and an unmarked 4GB card, dual boot with android.
are some roms better than others or is there anything else i can do or is that just how it is?
tried full clean format of card etc.
did you try insert card on already installed WP7 or you flashed ROM with card inside?
you cant only insert card... you need to make hard reset or flash ROM to use new card...
http://www.wpcentral.com/first-offi...-certified-microsd-card-announced-sandisk-8gb
same with my 16g Transcend, WP7 doesn't recognize it while flashing, what I did was use an 8g Sandisk then just made an image copy of that to the Transcend then it is OK, but during the flashing it wont see a Transcend card
you guys need to realize it's not always about the sd card that causes problems. the particular wp7 rom flavor causes incompatibilities. also, you can't copy existing wp7 sd images and expect it to work. just make sure the sd card is formatted in any of the std windows/dos formats...fat16, fat32, ntfs.
also, i've never encountered sd issues with 4 different brands ranging from 8gb to 32gb sizes of sd cards using yuki rom, but these same cards have issues when trying to flash pdaj, ansar, and hd2o wp7 roms.
BTW
if I flash WP7 using the Transcend it wont work
if I flash Android using the Transcend it will work

that goes without.saying. android doesn't have such strict requirements as wp7. as i stated in previous post...other wp7 roms other than yuki rom seem to be prone to sd card issues.

hi,
@dxdy: as i said in my post, i dual booted with android on 2 other different cards ok (by imaging and resizing and adjusting partitions)
bad thing was losing half my sd just for win 7. and i didnt like the idea of swapping cards.
also, the battery issue does not seem to have been bottomed out with its appalling standby times.
thanks though to hjhjhj for that info. that was just what i wanted to know. interesting but strange that different roms see the cards differently.
locking an os to a removable storage card has to be one of the worst features i have seen.
at least with our HD2's we still have other options.
will fire up win 7 again and give it another go.
