Note: sorry for my english... :D

French version avalaible here : http://www.monsmartphone.net/gonfler-son-htc-hd7-a-32-go-t1036.html

If you think your HTC HD7 is too short with his 8 GB memory, here is a detailed tutorial on how to give it a little boost to 32 GB ! Here is, step by step, how to do it. You can clic on photos to get them in high res...

WARNING : this tutorial needs you to open your smartphone completely, and may unvalidate your warranty. If you upgrade your HD7, you do it at your own risk !!

Read this tutorial entirely before begining anything.

!!! This memory change will completely erase the content of your phone. Backup it before !!

You will need the following tools :

- A HTC HD7 (yeah, easy...)

- A Sandisk MicroSD 32 GB Card : Warning !! Ony some references are compatible. Check the compatibility list at the end of this tutorial.

- A Torx screwdriver - Size : 0.4

- A little plastic card, like a fidelity card (little size)

- Tweezers

- A piece of paper

Remove the battery cover, the battery itself, and you SIM card :

Now, you need to remove the bottom cover. To do this, insert the plastic card inside, and pull upside gently. It will be a little hard, just do it quietly until it "clics". Do the same on the other side, and finish removing the cover :

Take the screwdriver. At minimum, you will need to remove the 3 screws marked by red arrows. Personaly, I remove the 3 screws marked by the green arrows too for more confort. One of the screws is hidden by a VOID sticker (which unvalidates the warranty if you remove it). Either you don't remove this sticker, the other black screws will scratched by the screwdriver, and you will lose warranty in all cases.

Now, pull the plastic framework upside with your finger, to get access to the MicroSD card reader :

The MicroSD card is protected by a "metallic" sticker. Unstick it, and tear it below the plastic framework. You cannot remove it completely :

If you don't want to be annoyed by this sticker, place your piece of paper on it. Now push the memory card in his reader with the tweezers : you will here a clic. Release, the card will be ejected :

Take the MicroSD card with the tweezers, and remove it :

There you are. Now insert your brand new memory card, and reassemble your phone following the previous steps.

Once your phone is reassembled, put your SIM card, the battery, and close the cover.

To turn it on, push the two volume buttons, and keep them pushed while pressing the Power button :

Keep the volume buttons pressed until you see this message :

Press the Down Volume button to confirm the Hard reset :

Press again the Down Volume button to restart the phone. Follow the Windows Phone configuration wizard, then reboot your phone again (just a simple reboot).

And "voilà" ! A HTC HD7 with full memory !!! :D

Updated on 28th April 2011 :

Compatible 32GB card :

- Sandisk SDSDQ-032G-J35 (Class 4 - Asian market)

- Sandisk SDSDQM-032G-B35 (Class 2 or Class 4)

Avoid these references :

- Sandisk SDSDQ-032G-E11M (Class 2 or 4)
[HD7 General] gamefrick:
Wow...although I don't really feel like doing this, its amazing.

:eek::eek::eek:
[HD7 General] gamefrick:
If I ever run out of my "16GB" of space, ofcourse I'll probably be doing this.

But thanks for this..

How did you figure this out if I may ask?? Just snooping around ey!
[HD7 General] Slicerwolf:
I putting money on, that this voids your warranty.
[HD7 General] Wolfman017:
Of course it does void it...maybe I should add "steel balls" in the necessary tools list ? :D
[HD7 General] VizagDude:
Good tutorial Pal. and Nice pictures too. Did you see any issues related to performance or accessing your media and games after you upgraded the MSD card?

Thanked you for this thread.
[HD7 General] djcedric:
very good tutorial,thank you very much :)
[HD7 General] Wolfman017:
Until now, I did not notice any performance issue. I am filling up the memory with photos (6500 !) and music (about 20 GB).
[HD7 General] Wolfman017:
OK, HD7 charged with more than 6500 photos (2 GB), and about 20GB of music ! No problem, it rocks :)

I only noticed a longer boot time (about 1 or 2 minutes)
[HD7 General] loomx:
Just keep the 16gb card spare, put it back in if it needs to go back for warranty, simple.
[HD7 General] enyaj:
I haven't filled up all 16gb of my HD7 yet but I am really, really tempted to do this. I can't accept my HD7 not having a 32gb capacity. :-)
[HD7 General] Dizmatic:
Very nice tutorial. Good step-by-step instructions.
[HD7 General] antoniomistretta:
Thank you! ;)
[HD7 General] element332:
Hey,

i already swapped my HD7 card for 32 Gb one long time ago. And it works great.

I have a question to all the people who swapped their cards too. Did anyone tried to use the old card from WP7 phone in other different WP7 phone.

I have my old 16 gb card from HD7 lying in the drawer doing nothing and now my friend bought HTC Trophy with only 8 gb of memory.

So i was wondering whether he can put my old HD7 card to his Trophy...???? Is it going to work..?

THX
[HD7 General] enyaj:
Nice to see you here antonio. Do you still have your HD2?
[HD7 General] gbbsoft:
What about Class 6 card? Are they compatible?
[HD7 General] theclueless:
worth mentioning: you just need to remove the lower right screw closest to the sdcard (the one below the screw with "void" sticker), then slightly lift the cover up using the screw driver, then use a flat head to push the sdcard out/in, so you dont need to void the warranty
[HD7 General] rahan95:
Hello,

Where did you purchase your sd card fom ?

Struggling to find a decent dealer in France for a Sandisk 32 Go =(
[HD7 General] Wolfman017:
I bought mine from this dealer : http://shop.ebay.fr/labayatxi/m.html

But it seems he does not have cards anymore. Maybe you should ask him if he can get new cards ? I bought it 50€, and it had been sent very quickly (I received it the day after my order).
[HD7 General] xchuiix:
Nice!!! =)

I have a 32Gb on my HD2... and i´ll keep it there. 16Gb on the HD7 its just fine.... for now!
[HD7 General] dorianmuthig:
In every SD card is a small ARMv7 processor, a minute amount of RAM (likely in the magnitude of 16KB) and a little bit of software. You cannot change this nor can you change the software on the card. It looks like a hardware thing to you, the OS has no awareness of nor any influence on how that works.
[HD7 General] loomx:
Just found the biggest drawback of having 32gb card... When you update to NoDo through zune it does a backup of the phone... My C: is a 60gb SSD, and it was trying to back it up to that! it refuses to update unless there is space, so I had to uninstall quite a bit of things to make room
[HD7 General] dorianmuthig:
Yeah, I and I'm pretty sure a lot of others reported that to Microsoft when the pre-liminary update (build 7008) was issued.
[HD7 General] xmj000:
will this work

I purchased a SDSDQ-032G-A11 instead of a SDSDQ-032G-B35

Will it work in my HD7 or do I need to get another SD card?

[HD7 General] dorianmuthig:
It might work, but your 4K random write is a bit too slow, and since the performance usually degrades a bit after each cell has been written to once, I would not recommend you use that card. The cards with that model number I tested all were too slow with random access operations. You have gotten a good card of the bunch, but even with that I wouldn't use it, your applications will perform poorly or may even crash because of it.
[HD7 General] xmj000:
Ok I should probably look for a SDSDQ-032G-B35 class 2 card, does it matter if it is rated class 2 or 4?
[HD7 General] dorianmuthig:
Yes, it does. You can only use the class 4 cards from the Asian markets (model number ends in J35 or J35A), there are some available in Europe by now (model number ends in E11 or E11A) which perform too poorly for Windows Phone 7.

[HD7 General] yfbc:
Just ordered a SDSDQM-016G-B35 for my 7 pro.

Do know anything about the abilities of this particular card?
[HD7 General] dorianmuthig:
Any problems you have are gonna be your problems. I do not work for or am otherwise affiliated with SanDisk in any way, I just tested cards. Working cards had either Toshiba/SanDisk flash or Samsung flash. For end users the SanDisk cards are just the only ones you can buy, since Toshiba and Samsung branded cards are OEM only.

No, I haven't tested that one, since most would just go with the 32GB card or buy the 16GB version of the phone. If this card is from the same process as the SDSDQM-032G-B35 it should, in theory, work fine.
[HD7 General] xmj000:
I cannot find the Sandisk Class 2 SDSDQ-032G-B35(A) anywhere in the US, I have a chip on order but I fear it is a Class 4 which wont be any better than a SDSDQ-032G-A11

I guess I just need to buy some random 32G SDHC and check their performance
[HD7 General] dorianmuthig:
You can find it on Amazon, just enter the model number in the search bar, and then select the one with the best price. If they end up sending you the wrong one, you can just send it back for free and have it (hopefully) replaced with the right one.
[HD7 General] yfbc:
Yeah I tried to find the 16GB version but couldn't find anyone stocking it so just brought the 8GB one.

I downloaded the benchmarking software you are using, it seems to take ages to run the tests (30+ minutes on 4000MB 1 pass), is this usual or an issue I'm having?
[HD7 General] dorianmuthig:
Are you sure you changed the number of passes to "1", the default is "5", if you newly installed it.

Here's a picture:

Also, you need a native SDA or USB2.0 SD card reader, a USB1.1 reader will be very slow and won't produce any accurate test results anyway. If you are testing a card, yes the test will take longer than 30 minutes, you can do the math yourself: "4000MB/???MB/s" = time for one test type, tests * 9 (first is preparation = space allocation with random data). The 4K random tests will take ~1 hour or more, depending on the average speed of the card.
[HD7 General] uiqjirka:
delete please
[HD7 General] dorianmuthig:
Well, that you can't use a miniSD or full size SD card would've been kinda obvious...
[HD7 General] xmj000:

The 512K random write speed (marked in red) does not match the class specification of the card. Return it and ask for a new one.

Also, you need the SDSDQM-032G-B35 which is sold as a class 2 card, not a class 4 card.

Q
[HD7 General] dorianmuthig:
That card's 4K random write is too slow.
[HD7 General] enyaj:
What Class does it say? I bought a 32gb with the same Model ID with class 4 and it did work but was slow. I saw a class 2 card with the same Model ID but I don't know if that will perform better.
[HD7 General] loomx:
Okay seriously...

I have a card in mine that you say doesnt work, and its perfect.

My friend with a HD7 bought one of the cheap SanDisc 4gb cards for about £50 a while back and because of this thread, did not put it in his phone, yesterday we tested it out in my HD2 to see if it worked, it did. So we gave it a chance in the HD7.

Cheap 4GB card works fine, apps open faster than the standard 16gb as well.

So either me and him have both been extremely lucky, the HD2 does something to make the cards work or NoDo is compatible with more cards... Or they just work!
[HD7 General] dorianmuthig:
Well, of course it works with any standard microSD or microSDHC memory card, the performance may just be different (e.g. slower) than the approved card models used by Windows Phone manufaturers.

Well, there have not been any 4GB cards tested as this seems to be an odd choice considering most people want more space or more performance but rarely, if not never, less space.

No, the HD2 doesn't do anything to SD cards that improves their performance in any way. Writing data to SD cards actually decreases their performance over time. The only reason why you need some specific and special performance rating for your SD cards with Windows Phone is achieving consistent performance and sufficient performance for application use. On Windows Mobile 6.x or Android your settings and user data usually go into the host memory while you store large files like applications, videos and pictures on your SD card where only sequential read and write matter (you need a fast card for HD video recording, though). On Windows Phone 7 you don't know if your data will go to the SD card or the internal memory, because of the hardware abstraction layer presenting both storage spaces combined to the OS and applications.
[HD7 General] Dr.8820:
Just wanted to update my progress so far on mine (not trying to argue or debate with anyone, that Verizon card I got, many others did too last year)...32gb class 2 SanDisk..1173 songs..pictures, apps and videos, just installed nodo yesterday, no issues, no memory leaks and I got the faster loading of programs :).
[HD7 General] dorianmuthig:
Just so I get this straight, do you work for Verizon or have some kind of other deal with them that causes you some sort of gain, if they sell their stock pile of SD cards? Because not only are the cards I listed as tested less expensive, if you order them online, they're also guaranteed to work, because they're tested, which for your card, I absolutely cannot say, even if yours apparently works fine in your phone.
[HD7 General] jatman:
Well, I thought I let you all know about testing Lexar 32GB Class 10 card (again) with NoDo update. With this update, WP7 will detect it being an "unsupported card" right away and you don't have to wait for few days to find out that card isn't going to work ;-(.... Looks like I need to spend again on a supported 32GB card.....
[HD7 General] Dr.8820:
Do you work for SanDisk? Alot of us @ ppcgeeks bought that card last year and I'm reporting for those that want to know. Please stop trolling my posts :).
[HD7 General] loomx:
Oops I ment class 4 32GB... it was one of the cheap ones from ebay that was said wouldnt even work, let alone be the right spec. Its working fine.

WP Bench is out now which benchmarks your phone,

By the looks of that, it would seem this card is pretty good to me.
[HD7 General] dkp1977:
I just upgraded my HD7 to a 16 GB class2 Kingston SD card. It works, but I have to admit that at least the installation of apps is darn slow. It took me the whole afternoon setting up the device the way it used to be. I'm currently installing the last 8 apps. After that I'll perform a WP Bench and see whether the card is really slow or not.

[Edit]

Alright, according to WP Bench the Kingston SD card hat a transfer speed of 0.26 MB per second. I replaced it now with a Sandisk class 2 SD card. Now it's 3.89 MB per second which is even faster than the card my HD7 came with (2.6 MB per second).
[HD7 General] enyaj:
So are there any new working Model IDs?
[HD7 General] Wolfman017:
Hi,

did someone tried this reference : SDSDQM-032G-B35N ?

Edit : and for those who upgraded their HD7, please report the reference of your working card...
[HD7 General] ramad76:
THAT is simply amazing .................... WOW

Thank you ... and i have question please ... can we use other kind of Cards ?????

once again many thanks And all the best

I think that's the one I tried. it worked but lagged so I went back to the original. I couldn't find any other Model ID
[HD7 General] zeka1974:
Hi guys,

Just ordered today my 32GB card:

Sandisk Class 2 32GB microSD - SDSDQM-032G-B35

Next week I will try this change :D

Thanks,

Santos
[HD7 General] detox8907:
I can confirm SDSDQM-032G-B35N class 4 is working :-)
[HD7 General] dorianmuthig:
Any Class 4 or below SD card will work in the device, that doesn't mean it'll perform well with the operating system of the phone and how its storage is going to be used.

You should test the performance of your card by filling it completely and then running CrystalDiskMark with 1 pass of the largest block on it. Post the results by selecting Edit -> Copy in the application menu.

I tested a few cards, the list of the working and properly performant ones is here: http://xdaforums.com/showpost.php?p=10354934
[HD7 General] enyaj:
It doesn't lag on you? Because when I used it, it was really laggy.
[HD7 General] detox8907:
Actually I take my statement back. It lags very much. :-/
[HD7 General] zeka1974:
Hi guys,

Anyone tried this card: SDSDQM-016G-B35 ?

It's compatible with HD7?

[HD7 General] dorianmuthig:
It will be compatible and work, but it may not have the performance required. Please test the card using CrystalDiskMark with 1 pass of 4000MB and post the results.

sandisk 32gb class 2 vs sandisk 8 gb class 4

hello,I replace my sd with a sandisk SDHC 32 Gb class 2, but after upload my files, the phone crasched and restart every times.

I change it again with the original 8Gb that is a Sandisk SDHC class 4.

Any suggest?

why you reccomended a class 2 and the original sd is a class 4?
[HD7 General] zeka1974:
Hello,

Did you check the reference of the card?

SDSDQM-032G-B35 was tested and no problems were appointed.

I'm waiting for this card to make the change :D

[HD7 General] zeka1974:
Hi guys,

have a friend that wants to buy a 32GB for his phone but he is in doubt regarding Sandisk or Kingston.

i talked to him and told him that Sandisk SDSDQM-032G-B35 works, but he has preference for Kingston SDC4/32GB-2ADP (Kingston is cheaper).

Is this a good card for WP7/HD7?

Thanks,

Santos
[HD7 General] dorianmuthig:
No, you shouldn't use Kingston cards and they will likely not work, because Kingston doesn't make the cards, they buy them in bulk from Toshiba/SanDisk and Samsung. Whilst all SanDisk cards are compatible with the SD controller in the phone, not all cards perform the same and only a select few meet the Windows Phone 7 Series performance requirements. There is no way to tell where Kingston sourced their card and from which plant or manufacturing process they originated. Some cards Kingston buys from these third party vendors are also phase out cards that work, but didn't meet some testing criteria at the plant. You may get lucky, but the odds are slim you get the right card.

If you look online, the price of the cards I recommend is about the same, if not less than comparable cards from rebranding vendors.
