New Tmo HD2 Micro SDHC problem

Ok, after having an Xperia X1 I gave in finally to the HD2. Man is it fast. I've already HSPL, Task 29, and flashed it with Energy ROM. My problem is everything works as it should including the storage card, but after I start playing around with it and it resets it stops recognizing the storage card. If I perform a hard reset, it recognizes it. If I go to boot loader it recognizes it. But after a couple soft resets stops recognizing it. What problems should I look in to in trying to resolve this?
Thanks.

Try removing it, booting the HD2, then switching it off and pop the card back in, does it still not see it?
Is the card the one that came with your phone?

If it is a stock SD card, then get it replaced, they suck. I had to get a new one before I walked out of the store .......

And no, it's not the stock card. It's a Sandisk 16 GB. I heard the stock cards weren't any good. But even with playing with both cards it still doesn't recognize it. This is very frustrating.
Could there be a possiblility of it being a ROM problem? I'll be honest and admit that I didn't even test it when it was stock. I just charged it and did the procedures to flash it and revert to the ROM that I'm use to on my Xperia. Or could it be a faulty phone?

It might be a faulty phone, but you should try different ROMs, see where that brings you.
EDIT: Lots of ppl have trouble with 16GB cards, but if you say that you have the same issues with the stock one, then...

My Xperia recognizes both cards, but the HD2 doesn't anymore. I even reformatted the both cards to FAT32 and both were recognized. So I copied some programs over and installed them...soft reset, and now it's not recognized again. I'm getting frustrated. I found that another member has stated that his class 2 didn't work, but class 4 did. But I thought Classes don't affect whether it's recognized or not, but the read/write speed?

dude try this, I've been doing this a couple of times and it works for my T8585. You insert it into a card reader then plug it to your computer. Most often a message appears on your computer screen telling you to fix your card (I use windows 7) but just ignore it. Then copy all the files in your card to your computer, plug it out and insert it into your phone. You can try and tell me whether it works for you.

SDHC problem
Hi, i have similar problem. When I insert SDHC (4Gb class4),Device dont recognize, but when i plug into USB and press Disk drive,RECOGNIZE. I have HD2 T-Mobile, Energy ROM/Stock ROM...
Can somebody HELP ME ?

[Q] Why is my SD card not responding?

I can't seem to get the NAND work properly.
Every step went well, but maybe I forgot something.
Once I flash the ROM I reboot it twice.
When I start marketplace and download apps, they disappear from the download list. They don't get downloaded at all. With another ROM I tried the download part works, but after the install the app doesn't seem to work. After a few times plugging in and out the USB I got an error about my SD-card being ReadOnly. Am I doing something wrong? I didn't manually make partitions or anything on the SD card, should I have done so?
Also I've noticed that after I put files on the SD card and unplug the phone from the PC, astro can't find the files. Really confusing
Does anyone have the same problem or know how to fix it?

First of let me tell you that I have never had this kind of problem neither I have heard about this problem. But one thing you can do is use Panasonic SD formatter (Free) to format your SD card. Do not mount your phone on the PC. In place of that remove SD card and use some kind of Card Reader to format the SD card from PC. Also keep Full Erase (ON) in the settings for formatting.
I would also recommend you to do Task29 before flashing new ROMS. After you do Task29 install radio (2.15.xxxx preferred), install MAGLDR 1.11 or 1.12(I would not install 1.13 which is released recently. Wait and watch for that version), After you perform these steps, you should install NAND ROM on your device. Also try and find the Rom which has more versions. What I mean is for newbs like us, we should try roms which have been tested by many other PROs. and also there are plenty of video tuts on how to install NAND rom. Follow them closely.
Here is a good tutorial that might help you. http://www.youtube.com/watch?v=91mnfufny-Q&feature=player_embedded

I did exactly what you said, but I'm still having the same problem. After I installed the NAND rom I connected my phone to my pc and dragged some files on the SD. The phone didn't see any of them, so I took my SD out and formatted it. But now it's not recognizing my SD at all. I will try some other roms.

I had that problem some mounths ago. One day it was gone. i cant tell why

I have a similar problem. To work around it I remove the sd card and reset the phone with the red button under the battery cover. When it comes back up, i insert the sd card and all works normally.
Our problems arn't exactly the same but worth a go if it helps.

after a long search i found this:

and the fix from ehsan worked !
no problem downloaden and no problems with the SD anymore! woohoo

[Q] Micro SD card useless after installing Back to the Future [XBmod-Yuki]

Hello everyone, I've recently installed Back to the Future [XBmod-Yuki] with kingston 8gb class 4. Everything was fine until i pressed 'reset ypur phone'. The phone started crashing on htc logo , so I decided to go back to wm 6.5. The problem is my sd card is no longer recognisable by anything. I tried SD formatter, hard disk low level format tool, killdisk, mitool partition, but with no luck

Or
Youtube type in search(video from 96edwy)......> htc hd2 how to format your sd card after wp7 use

thaks for the help, but both methods are not working, i've installed storage lock, but my sd card is no longer recognised by the phone itself. when i go to mass store, my pc is not finding anything either.

i have the exact same problem i also tried with the cab sender but had no luck if someone could please help us i actualy lost 2 8Gb sd cards

I had to get a new sd card for similar case.

all the solutions they gave in the forum didnt work for me, only this worked:
be carefull never do a reset from the about menu cuz this was the reason all my cards got locked <- im on this now for over a week, so believe me i tried everything, but its never useless to try it yourself because in my opinion you cant talk about a general state of cards or wp7 installation.
Reflash everything with your card inside your mobile, i mean start with windows 6.5 then the radio then magldr and then the native rom from yuki,
as it boots up wp7 you should get stuck on the htc screen because your sd is broken, now empty the sd bevor the phone has booted, and enter it in your sd reader, windows should now detect the card.
this only worked for one of my cards. and no its not depending on the brand because i have 2 sandisks and with the 8 gb it worked... with the 2gb it didnt...
but i still couldnt manage it to get to mango.

I had troubles to install WP also, I just tried again today, and I have it now!
I installed it from cabs, following more or less this:
http://www.jayceooi.com/2011/09/16/how-to-install-windows-phone-7-5-mango-7720-on-htc-hd2-video/
I downloaded 7004-7392 and 7392-7720.
I installed in 3 update steps:
1st I installed the ROM,
then 1st update 7004-7392
then I installed all cabs to get to 7661
then I installed all to 7720
Had some troubles, but by keeping trying, I got it
Now I have my red mango!
Even if it is still bugging because of my sd card... Now It freezes 1 second after being loaded.

Had that same issue, just hard reset on magldr (power on, vol up and volume up again) and problem solved.

at the stage of 7.392 to 7403 it gets stuck with me cause of the sd card it wont update and then it gets into a boot loop, its definatly the boot when i need the sd to update, the boot kills my sd and it wont recognize the updates, any trick how to get over that boot which kills the card? any way to get the updates to the card without doing that reboot on wp7

I don't have a solution to the SD unlock, BUT I can tell you that people SAY that if you put the SD in a Nokia device and format it, it will be usable again. I gave myself a serious scare as I thought I had destroyed 2 SD cards, when not even WP7 recognized them, but I found out that if you do a Task 29, install radio 2.15, MAGLDR 1.13, enable 24mb nand and clear SD MBR, then install the ROM again, the phone can read the SD once more, thus meaning it is NOT DESTROYED and salvageable. Hope this was somewhat helpful to anyone else that thought like me he had destroyed his SD!
VERY IMPORTANT: WP7 stops recognizing the cards if you take them OUT of the device, so if you want to save yourself an hour of reflashing DO NOT UNDER ANY CIRCUMSTANCES pull your SD out. Otherwise you will need to reflash if you want the phone to see the SD again.
EDIT: Read my next post for the solution! Hope this helps

How to format a WP7 secured card
Hey guys,
I have flashed WP7 from initial builds to NODO to Mango so many times that I have lost count...
With NODO I have had success in formatting the card with my Nikon D90.
Cards started to be locked in Mango. The only solution is to format the card with a Nokia C6 or any Nokia with Symbian v8 or above.
I have tried every tool and every tool is dependent on the OS for initial recognition, and OS (Window 7) simply refuses to recognize the "wp7 secured" card.

I managed to salvage my SD card using a SD-adapter and the built-in SD card reader of my netbook... (Android, CWM, and 5 USB card readers didn't work) windows recognized the card as a 200MB card at first (?..)
used SD formatter to restore the original size to 4GB

Oh rly
Because I manaed to reformat my SD WITHOUT ANY CAMERAS OR NOKIAS
All you have to do is use the DEV_UNLOCKSTORAGE.cab and that will unlock your SD which can then be read by your PC and reformatted with SD Formatter 3.0!

I think I realised your problem and I'm sorry. I had missed the part where he says the PHONE can't recognize the card either.
Same thing happened to me, but I just:
1.Ran task29
2.Installed 2.15 Radio
3.Installed magldr 1.13
4.Went into services (WITH MY SD CARD IN MY PHONE) and I picked Clear SD MBR (i don't know if that really helps, but just in case it does)
5.Enabled extra 24mb nand and I flashed the ROM
6.Then I updated to 7720
7.I installed DEV_STORAGELOCK.cab and unlocked my SD, i turned off my phone, I took my SD out and My computer could now read and Format it.
I am truly sorry if this is another "stupid" solution.

So you installed WP7 that locks the card all the way to Mango, installed the DEV_STORAGELOCK to unlock it with a .cab in order to be formatted on your PC? Sure thing, stick with that method, it works...

Are you sarcastic? I mean really are you. Cause I SWEAR it works. The card may be locked, but builds 7004, 7392 can still see it just as well as 7720, but I think you need to be on 7720 in order to use DEV_STORAGELOCK.cab!

[Q] Locked SD Card (another question! i did read :) )

Hey Guys,
I did something remarkably stupid I think.
* SanDisk 8GB Class 4 SDcard
1. Installed WP7 Mango
2. Got an error message about the SDcard and couldn't use that anymore
3. Hard resetted the phone with my 4GB class 2 Sandisk card and started using that one.
Now... when I place the 8GB in the phone, it doesn't boot. It's just stuck on the HTC screen and doesn't go from there, so I can't unlock this one. (No Nokia's laying around, and the cab files don't really work, as I cannot boot with the 8GB card).
If I would start from scratch (stock...). Would I be able to 'revive' the 8GB card, by formatting it when installing WP7? (It creates the partitions and stuff in MAGLDR).
If not, I have no idea how to revive this card anymore
Please advise

Never mind, this doesn't work either. Good bye 8GB Sdcard...

Yep, tried that too. I spent the entire day yesterday trying to fix it, but I just can't get this to work. The SDcard is not being recognized anywhere.
When starting with Mango is says the card is not functional, and the only options I have is "emergency call" or "close" >> meaning the OS will be shutdown.
EDIT:
For some reason, the complete re-flash worked!
It took 41 minutes(!) for the OS to boot! But now it all seems to be in order
Is there a way to put this to "solved?"
Edit2:
my SanDisk 8GB SDCard clearly does not want to be used with MANGO. Switching back to 4GB. No other way

Please can you explain the procedure you undertook to resolve Your issue?
What did you reflash with corrupt sd card? Did you use storageunlock.cab?
Glad you got there in the end

Nope, I just started from scratch. Flash stock - Task29 - magldr - wp7, all with the sdcard inserted.
For me eventually it didnt work out as the card got locked again..

Sorry, yes. I installed WP7 Mango (XBmod-Yuki rom V2), SD card was formatted and locked. I removed WP7 without knowing this would happen, and now I can't get the card to be recognized in Windows, Linux, OSX, or any of my other devices that support MicroSD. Been searching for a fix, but it looks like I'll need to find a Symbian device to format the card.
After I posted before, I was able to reinstall the original WP7 rom and the card was recognized after a hard reset, but I'm not having any luck getting the unlock cab to work. Actually, now, after trying to send the cab to my device, restarting with the card in the phone or doing a hard reset results in the phone just not loading the OS.
Sorry for being long winded, but I'm just about out of ideas. Thanks for any help

The way I fixed that is an aweful thing to do, but it worked.
1. Flash to stock Windows Mobile 6.5 (with locked SDcard in there)
2. Task29
3. Install MAGLDR
4. FLASH WP7 (still, with that same SDcard in there)
After it's flashed, do not update, but take the card out and stick it in a card reader (hell, even the magldr >> usb storage function works).
Windows will detect 200 MB on that card. Format it with SDformatter and it will be good again.
Note: That specific card is not compatible with WP7 MANGO, so don't try to use that ever again ;-)
It took me a week to figure this out, but i successfully managed to revive my 8GB Sandisk Class 4 card, which I now will use in my camera instead of the HD2
Hope this helps!

AWESOME!

I'm going to try this, but I'm wondering which WP7 Rom you flashed. I originally was using the Yuki Update rom, then once all the badness happened, I flashed to a much older one, then back to Yuki. However, in each of those cases, I never got the 200MB partition. Anyway, I'm giving this a shot, will let you know. Thanks!

Hey again all,
It's possible there's something else wrong with my card at this point. I tried Krewsia1nl's method and it seemed like it might work, but I still never got any additional partitions that my PC could recognize. I tried it a couple of times, 12st with an older WP7 rom I found in the HD2 WP7 dev section, and 2nd with the original Yuki rom I was flashing. Same issue in both cases.
What I did find is that I can see the card in the Yuki rom after flashing, BUT if I restart the device, it freezes, I have to remove the card to be able to boot it, and when it reboots, it tells me I must insert the card to continue. Great...
This also poses a problem with unlocking the card in WP7 with the unlock or partition cabs. To install them, the cab sender restarts your device. Once that happens, my phone freezes and I have to remove the card. All subsequent attempts to reboot or reinsert the card are met with either nothing recognized, or an error (It's also important to note that I can only see the card on first boot after following Krewsia1nl's method-if I try to hard reset with the card in, the phone just keeps freezing).
So, for now, that's where I'm at. I'm going to try the UBCD Killdisk method and I'll report whether or not that works, in case anyone finds themselves in this particular, sinking boat. Killdisk Method is here:
http://forum.xda-developers.com/showthread.php?t=1280293
Thanks again for your help, all. Love XDA <3

Killdisk didn't work either. Guessing my card is fried, but I'll still try a Nokia if I can find one.

I also tried to install Yukis Mango 7720 but not with good result.
Does this 7720 work in any HD2...
Ubuntu doesn't do anything if you add your WP7 SD card to reader.
Win7 shows that you have "Removable Disk" but if you try to access it Windows says "unable something....".
I thought that I have also two fried SD card because this 7720 testing.
But Nokia E51 format successfully both cards )

i have an old Nokia 3650 and a few cards that mango has ruined. Now if I can just find the plug for the nokia......wonder if it will format them ?

I also tried to install Yukis Mango 7720 but not with good result.
Does this 7720 work in any HD2...
Ubuntu doesn't do anything if you add your WP7 SD card to reader.
Win7 shows that you have "Removable Disk" but if you try to access it Windows says "unable something....".
I thought that I have also two fried SD card because this 7720 testing.

Can you tell me what SD Card did you manage to unlock?
I tried an E63 for my Sandisk Class 4 32Go unsuccessfully

What an absolute disaster the BTTF Yuki rom is...It is inevitable, most will lose their sd cards, it cost me $45 to replace. Could we put a BIG warning up for these roms, GUARANTEED to destroy your SD card? Because it will, at some point for sure, you will reload the rom and that's when the fun starts..AVOID AT ALL (cough) Costs...

You are completely entitled to your opinion and to post it here.
Many people have successfully upgraded to Mango and have not posted here at all.

I'm sorry, did not intend to knock the rom, the rom is excellent, the concern, it will ultimately cause you much duress as to the sd card at some point, that's my only point. Not many folk expect to lose the sd card after installing... and reinstalling...yes, there are work arounds, but, they entail, much ado and worst case, nokia.kodaj devices...there should be a MASSIVE warning as to SD card...yes, the small print offers cabs and tinkering to avoid the 'lock', but most of us don't expect any such chicanery.-)
