I skimmed through most pages in this thread...

I have a friend with a 16GB version of this phone and he wants to upgrade. I have seen some people who got a 64GB card working? if this true, if so which brand/versions are recommended??

Also, at this day and time which brand are recommended for a 32GB card?

He's budget is not so big as to buy too many cards :P

Edit: I found this thread Which gives me an 64GB candidate but I want to hear more suggestions if possible before I tell my friend which to purchase.
[HD7 General] xdrc45:
The 64gb sd cards will work on the HD7 but is has to be on a current bootloader version of 5.12 to support the SDXC cards. Therefore the device can't be unlocked and running a custom rom, (if that's your friends case) because the bootloader version won't support the SDXC cards.

Almost all newly manufactured SD cards will now work. It's always best to use a higher quality name brand SD card though.... SanDisk or PNY. These will be less likely to have issues with Read/Write speeds, compatibility issues or overall failure of the card.

Same would apply for the 32gb cards, use a better brand. I have a 32gb PNY class 4 sd card in my HD7 with a 3.xxx bootloader version and it works prefectly. Pretty much any bootloader version should support the 32gb cards too.
[HD7 General] xXLostsoul111Xx:
Thanks for the information. I need to check which bootloader is running but the phone is stock rom so it shouldn't be too much of a hassle.

Hello, if this cool trick is applicable for HTC 8S? Since 8S section is not very active.

thank you

You can try to hit Google? ;)
[HD7 General] Linkestis:
Yes, of course I read the entire thread about 10 times, and Google also

The question is whether the HTC 8S is the same principle that some risked it.

Sorry for my bad English.

Good luck to all and admire what you are doing here.

Thank you
[HD7 General] Dr.8820:
This is achieved by taking the phone apart. No one has attempted this with the 8S...yet. If you're asking if it takes a 64GB card in the slot, it should. But once again, we are talking about taking the memory card out to increase storage internally with the HD7 here ?.

Good luck!

For any Aussies

Excellence. Went to DickSmith here in OZ to pick up an SD card, but apparently they don't sell them anymore (at least not in store). So used a DickSmith brand 16gb Class 4 card (expensive as hell at 30 bucks tho!) and it seems to be working just fine. Easy peasy, took about 10-15 minutes to do this all!

Reason for doing this, as well, was because my memory card had the Failure message that comes along with HD7's now and again. Now works just fine again.

Thanks for the detailed instructions!

Installing more memory, 7.8 & sounds for SMS/email

Hi, it is time for me to hack my HTC HD7. I want to add as much memory as possible. Can we extend it up to a 64gb or is 32 the limit? In addition, what is the best way to unlock my phone so I can install 7.8 as well as use customized sounds for SMS, email and reminders? Can anyone suggest the proper solutions and the correct order. I'd hate to have one operation wipe out another. Thx J
[HD7 General] ThomasKIK:
yes you can add 64GB and the best way to unlock your phone is to load a custom ROM on it you should try the newest 7.8 ROM

[HD7 General] dorianmuthig:
There isn't any possibility to do this without voiding your warranty. The only thing you can do is send your phone to be serviced by a third party who will give you another warranty with the replacement of the storage card.
[HD7 General] ricklo19:
Ok, that sucks. I just ordered a 32 GB class 2 and received a 32 GB class 4. Now that I have it anyways, has anyone tested a 32 GB Class 4 Sandisk SD card? Just checked out the other thread and it says that it hasn't been tested yet with this card and it also says that the 32 GB Class 2 Sandisk SD card is actually faster than the one that came with the device if you look at it statistically. Let me know. I would try it but I need a damn torx screwdriver at the moment.
[HD7 General] dorianmuthig:
What's he model number for that card? You can see that on the back of the packaging right above the UPC/EAN barcode.

According to Sandisk the class 4 cards are being shipped to distribution channels this month and are going to replace the class 4 models, just like the class 2 models have been replacing the class 0 ones.

If you've got an authentic Sandisk card it should work just fine. If you're worried, use a USB 2.0 SD card reader and test the card in your PC with this software. Pick the largest amount of storage to test, select the drive with your SD card in it and click on All. Post the results if you can.
[HD7 General] Wolfman017:
No, this Class 4 will not work. I had ordered a Class 2 the first time and received a Class 4 too : the card was not recognized at all.
[HD7 General] dorianmuthig:
What model number did your card have? It needs to be SDSDQM-032-J35A for class 4 or it won't work. So far you can buy that memory card only in Japan.

Query regarding the metallic sticker protecting the MicroSD Card

Can anybody tell me what is the purpose of this Metallic Sticker which protects the MicroSD card?

I guess I should start at the beginning.

1) My HD7S ( AT&T factory unlocked, working on Vodafone India, upgraded to 7.8 recently ) started giving me memory trouble. It seemed the memory card was corrupted, in about, the total memory being shown was ~ 13 MB. A quick search on this forum led me to this thread and I was relieved to find this solution to my woes.

2) Purchased the compatible Sandisk 32GB MicroSD card.

3) Opened up the phone as per the intructions in this thread.

4) Accidentally damaged the abovementioned metallic sticker while removing it, it did'nt stick properly after that so I just tore it off ( I'm not sure why I did that now )

5) Change Memory card, start phone again ( without the SIM ), and check memory. Yay, 32 Gigs working.

6) Insert SIM card, restart, but now the phone is not recognisng the SIM Card. Try pushing the tray down, try removing and reinserting the connector pins( found in another thread I think ) but no avail. My Phone has become a SIM-less mini-tablet. Everything works, except the SIM.

Now there are two things I could have done for this to happen -

1) Damage the SIM card slot while removing the housing ( I might have been a little rough )

2) Tore off the metallic sticker ( Since it is Metallic I hope it did not provide some sort of contact that I broke )

Also, since it is a factory unlocked AT&T phone (purchased Unlocked), is it possible that the change of Memory card caused it to lock again? All the other features of the phone work, I can connect to the Internet via WiFi, the camera, the Music Player etc etc. It's just the SIM card that is not being detected.

So what do I need to do to get this functional again? Do I order a new SIM + Memory card tray ( ~ 15USD on Amazon), do I delve into the world of unlocking or do I keep using it as an iPod touch and start saving for a 8X or a Lumia 920?

Help will be appreciated. And if you are in Mumbai or Amsterdam, I can buy you beer if you tell me how to fix this :)

Thanks.

[HD7 General] ricklo19:
Ok, this was my result of a 32 GB Class 4 Sandisk Micro SD card.
[HD7 General] dorianmuthig:
First of all you need to test a single run of 4000MB instead of 5 of 1000MB. Secondly, this isn't a class 4 card, but actually a "real" class 0 card (see large block random write speed marked in red). This can cause problems with video recording, when you've filled your card with smaller things (photos, apps) and then deleted a few inbetween. The odd part is, your 4K random write is faster than your 512K random write, which would be good if it is consistent, but since you only tested ~3% of the card, likely at the beginning of its storage space and with the OS's cache (RAM), there's no way to tell for sure. Granted, though, your sequential read speed looks great, but again, you only tested a small portion of the card which also easily fits in the OS cache.

Please test it again using the 4000MB option and run it only once, running it multiple times only skews the results and wears out your memory card.

[HD7 General] dorianmuthig:
If you would like to be able to use your old SD card in another phone or your computer, you will need to format it using a device with secure digital password protection support. You don't need to know the password for that. Most Symbian devices can do this, if you don't have one, try to ask the nice person in your local mobile phone store to lend you one for one or two minutes.

Hey! Thanks for this great tutorial, wolfman!

Went to the next store today to buy myself a 32GB MicroSDHC and they had the exaxtly same card that you've bought (even with the free music :D). So, I managed to install it in my phone without removing the three screws marked by green arrows, so that I don't have to damage the "Void"-sticker. It worked perfectly. I had no issues at all and the phone is exactly as fast (if not even faster) as before. Games are as fast and smooth as they were on my 8GB Class 4. So, I'm totally satisfied here! Has anyone experienced issues with the Class 2 cards? Regarding performance, for example...
[HD7 General] ricklo19:
At first I didn't want to try the 32GB Class 4 Sandisk because people keep saying class 2 only. I decided to try it anyways, and guess what? The 32GB Class 4 Sandisk works!
[HD7 General] nrfitchett4:
sandisk doesn't make a class4 32gb:

http://shop.sandisk.com/DRHM/store?...parentCategoryID=11442400&categoryID=11779700
[HD7 General] Z80-Man:
Let's face it : Sandisk makes very good memory cards, period.

On most devices, the problem is the more important current consumption with higher classes memory cards, so if the builder says "class2", then at least you know you shouldn't have problems with class 2 cards.

A lot of people are having problems with class 4 Kingston memory cards, while you have none with Sandisk : the difference then resides in the way the cards are made.

Congratulations if you managed to use a class 4 32 GB card. You'd have less luck with another brand, however. ;)

I won't drop my class 2 Sandisk 32 GB card for a class 4 anyway : it works perfectly, I don't find it slow at all, and now it's there, there it will stay. :p

And can I get this card on Ebay ?
[HD7 General] dorianmuthig:
They're selling the SDSDQ-032G-A11M and SDSDQ-032G-P36M which are genuine class 2, but you need the SDSDQM-032G-B35A which is sold and marked as class 2, but has class 4 performance.

Better stick with the offer from Amazon I provided in the post above, because that card will definitely work and it's also only $95.69 with free worldwide shipping.

[HD7 General] Wolfman017:
Could you give your card reference ? The first card I tried was a Sandisk Class 4, and it did not work (not recognized by the HD7)
[HD7 General] dorianmuthig:
You need model number SDSDQ-032G-J35A, this genuine class 4 Sandisk microSD card is available in asian markets (Japan, Korea, China, Taiwan, etc.).

You can also use the SDSDQM-032G-B35, which is sold as class 2 but has class 4 performance.
[HD7 General] Fuze2009:
This might be a stupid question, but I've installed a 32GB Class 6 card in my HD7 and did the hard reset. Not the phone just gets stuck on the white HTC screen.

I'm assuming it can't read the card, or did I just destroy my phone?
[HD7 General] dorianmuthig:
You need to use a genuine SanDisk microSD card (class 2 or class 4) with class 4 or higher performance (sd card class is large block random write in MegaByte per second). Other cards will probably not work.
[HD7 General] Wolfman017:
The first I received was a SDSDQM-032G-B35, and it was not compatible with my HD7 (not recognized).
[HD7 General] dorianmuthig:
Did you try it in your computer first? Because, if you received a defective card you can have it replaced. Also, make sure it sits properly in the microSD card slot in the phone.
[HD7 General] Inspires:
can you go beyond 32gb?
[HD7 General] dorianmuthig:
In theory, yes. All it would take would be a bootloader update for SDXC support.

Unfortunately, no manufacturer makes microSD cards larger than 32GB (which the maximum for SDHC) just yet, not to mention that the added storage density would likely cause the performance to degrade to something too slow for the Windows Phone 7 OS.
[HD7 General] Wolfman017:
The card was working very well on my computer. But not recognized by the HD7.

Inspires --> MicroSDHC is limited to 32GB. Beyond that, these are MicroSDXC cards...not the same format.
[HD7 General] dorianmuthig:
Make sure you pushed it all the way into the slot, it'll make a clicking sound. Also, download CrystalDiskMark and test your card's performance in your computer.

That's not the problem, the card format is all software, which can be changed to support it. There are just no microSDXC cards available.
[HD7 General] Z80-Man:
Don't worry, it won't destroy your phone.

But now whe're here, Dorianmuthig's remark reminded me that sometimes, you should just try to reformat your card from your PC before trying again in your phone.

I just happened to my wife : I bought an SDHC card in New Zealand for her camera, and it told the card was locked (which it wasn't, of course). After a simple format on my EeePC (just from Windows, I didn't even had to use a more clever formatting utility such as HP's one), the card was recognized correctly and worked fine.

Anyway, if after having trying that it still doesn't boot, then just consider changing the card, as it's probably too fast (it actually consumes too much current from the phone).

That said... Just another thing : don't expect your phone to boot up straight after having changed the card. Remember WP7 uses some Microsoft Active Directory organization, so the internal and card memory are seen together as one unique whole lot.

You absolutely MUST perform a hard reset as soon as you power on your phone right after changing the memory card. I hope you didn't skip that vital step !!! :p
[HD7 General] mak213:

so, if im getting this right, only the class 2 card will work, and only Asian class 4 cards will work. just to make sure this card will work correctly? and doIi need to put it in my computer first or can it go straight into my 16Gb HD7?
[HD7 General] dorianmuthig:
Yes, that card will work, that's only the version with the transflash adapter (A at the end of the model number), the version without the transflash adapter is cheaper, though. http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias=aps&field-keywords=sdsdqm-032g-b35

And no, you don't need to put it into your computer first.
[HD7 General] nat45928:
ok, and if i get a class 4 card instead of the class 2 return it and keep looking?
[HD7 General] dorianmuthig:
If you get a class 4 card, it needs to be a SDSDQ-032G-J35(A) model. The class 2 card with the model number I mentioned has class 4 performance (test and determine MB/s speed with 512K random write), so it doesn't really make a difference.
[HD7 General] nat45928:
all is well and everything works except one thing.... the battery indicator wont work while and after the phone is plugged in untill a reboot is done..... any ideas?
[HD7 General] dorianmuthig:
The battery indicator shows a power plug symbol on top of it, if the battery is full and the device plugged in. This is normal.
[HD7 General] nat45928:
i know what you mean, but im saying things would go like this:

boot 1: battery shows a charge

plug in: battery icon would flash between the charge symbol and a empty battery, not showing charging progress.

unplug (~1hr later): "warning: critical battery"

reboot right away: battery shows a charge

repeat this and thats whats happening, i think it might be working now though, fingers crossed.
[HD7 General] dorianmuthig:
Please check your USB cable, your USB plug and your battery connectors for dirt and other resistant residue. It is very unlikely that there is a software issue.
[HD7 General] loomx:
Oh FFS, I ordered a 32GB Sandisk card and have now got a SDSDQ-032G-E11M which I assume is no good?
[HD7 General] dorianmuthig:
Well, it might work, but less than class 4 performance is usually too slow for video recording and playback. If it works, your phone will be very slow and might at times be very unresponsive when exiting apps and games.
