[7 Mozart General] BinarySolo:
Hey guys, I'm new to XDA and I've got some questions about upgrading the memory of my Mozart.

First, what kind of SD cards have you guys used to replace the original 8 gig? I'm looking for a 32gb card as if I'm going to do this I only wanna do it once haha. Can anyone who has filled their card up a fair bit and has been using the phone for a few weeks tell me what you're using? SanDisk C2 seems like the choice card for this but I'd like your opinions.

Secondly, does anyone who's done this procedure have any tips or tricks in dismantling the phone to access the SD slot?

And finally, can anyone tell me the specific starpoint screwdriver I'll need to do this? I'd be heaps more comfortable doing this if I knew the specific size and type.

Thanks,

Brad

Great info, just upgraded to a 16GB class 2- went nice and smooth, and only took 10 mins.

Cheers

with sandisk card u be sure it works well,i bought the 32gb class 2 sandisk since november & it work well,no crash,no data loss & it very smooth compared to the stock card ;)
[7 Mozart General] wkythomas:
Hi, I just got my Mozart updated with Sandisk 16GB class 2 memory.

All working.....Thank you so much Andy.

In fact, i did the memory upgrade because i accidently delete one of my file from my mobile. So my purpose is restore the file from my memory card.

I tried to plug the 8GB card to my computer, however it is not detected.

Is there anyway to make the card being detectable again?

Thank you

the first card certified for wp7 coming soon from PNY => http://bit.ly/gByNf9

Update: Commenter Adam points out that the marketing copy may refer to the fact that the bundled, downloadable movies are "now compatible with Windows Phone 7," and not the card itself. Still, according to wpcentral, anecdotal evidence suggests that PNY cards work well in WP7 devices.

Update 2: Yup, the developer behind the PNY app even issued a press release touting its Silverlight-powered movie player for WP7, so we'd say they're definitely talking about the movies, and not the cards.
[7 Mozart General] jasonmoore2k:
I followed the video guide, took me about half an hour because I was quite careful.

I switched the original for a Sandisk 32Gb Class 4 (SDSDQM-032G-B35N) and it's running very smoothly at the moment (without registry tweaks). Almost feels quicker than before, but that might slow down over time.

I'll come back in a few days and let you know if it's still stable.

Update (Day 4)

Has been running fine and stable, without any reboots or glitching. Currently sitting at 5.46GB used / 29.51 GB (I know! Still not taking advantage of the extra room - I haven't had a chance to sit down and rip all my music).

Hello a local store sells

sandisk 32gb class 2 or class 4

Which one is better for the mozart.
[7 Mozart General] nok_fusion:
buy the class 2,sandisk do not make class 4 on 32gb it's fake card

i have the sandisk 32gb class 2 for november it works well,quickly(more than the current card) no freeze or crashes,everything run perfect with it ;)
[7 Mozart General] kms108:
I think many ppl will disagree on your comment, sandisk does make a 32gb class 4 micro sdhc.
[7 Mozart General] nok_fusion:
just go on the website of sandisk & show us if your find one 32gb class 4 :rolleyes:

the Sandisk 32 gb class 4 u find are not from sandisk,i'm sure of that,they just fake card i just prevent people who will buy microsdhc card...

sometime you cannot rely on a web site to get the info you need, its a new product and web site can sometime be not upto date, you can try contacting them.

I have one of these, with 5 years warranty and I've checked for error, no problem what so ever.
[7 Mozart General] nok_fusion:
hmm i'm a bit skeptic but if u have warranty with it,it's ok ;)

Thinking of giving this a go

Hi guy's was wanting to try this on my mozart but i was a bit worried i might loose all my contacts in my address book as they are all on the phone and not on the sim card. i would like to keep my sms's too. is there a way to back all this up.

cheers.
[7 Mozart General] kms108:
i've just done the mod, and i can confirm that the lexar 32GB Class 10 does not work, ive was gonna try the adata class 2, but use the sandisk 32GB class 4 instead, the adata had a read speed of 11.5MB/s and write speed 6.5MB/s, agains the sandisk read 17.6MB/s and write speed at 5.9MB/s, in this case the read speed is more important.
[7 Mozart General] kms108:
after few days of use, I have notice after upgraded the 8GB to a sandisk 32GB class 4, my phone is unstable and with some lag, i have also notice that I do not get a full 3D animation run when the htc hub is pressed, when the 8GB memory was used, the 3D anime with the htc hub words and the clouds.

now i am using adata 32Gb class 2, i get the full anime and the phone seems to run faster and smoother.
[7 Mozart General] kms108:
I have a question, whether your upgrade is successfully or not, once you remove the micro sdhc, it is unusable, my PC will not detect it, even with the Panasonic sd formatter, does anyone have any idea to rectify the problem.

I have three half dead 32gb micro sdhc, waiting for suppliers to get stock in for exchange.

So unless you know which cards work, you take the risk of killing your micro sdhc.

Cards that works

SanDisk class 2

SanDisk class 4

Adata class 2

Adata class 4

Will not work

Lexar 32gb class 10

San Disk Class 4

Hello all

Just wondering if anyone has gotten a San Disk Class 4 card working?

I followed Andy's videos to install the above card, but after putting the phone back together I am presented with an error screen with ""Storage card not working" as the title. There is no option to reformat or anything, just options to make an emergency call or turn the phone off.

Thanks,

balog
[7 Mozart General] kms108:
Try reading through the thread, you'll get the answer to your problem.
[7 Mozart General] balog:
I've been through every post in this thread. Maybe I'm just blind.

Which post is meant to help with my specific problem? The problem of the new card (Sandisk 32GB Class 4) not working, and receiving the following error from the OS "Storage card not working"

Thanks in advance,

balog
[7 Mozart General] riyanpradiyar:
If I'm not wrong you can re format using any Nokia phone, are you sure the card not working? Maybe you can try again after re format the card, someone in this thread manage to install Sandisk 32GB class 4, I plan to purchase the same card as yours :(
[7 Mozart General] balog:
I've tried several times to install it now. First time the card was formatted as FAT32, which is the state it was in when i bought it. Second time i removed all partitions from the card. The third time I used the SDFormatter. Everytime it comes up with the error "Storage card not working". There's more to the error message, ill take a screenshot next time I try which will be in a few days as I broke off the microusb clip that's attached to the PCB. A friend is soldering it back on.

After the first couple of times I thought I might have a dodgy card so I ran it through HD Tune Pro. All the measurements came back matching other benchmarks published for the card. No errors either. I also ran a utility I wrote which checks the validity of usb flash drives and cards. It also passed this.

Not sure what to try next. I will need a working phone first.
[7 Mozart General] kms108:
you will have to reset the whole phone to have the memory card to work, once this is done, the card will not work if you decide to remove it from your phone.
[7 Mozart General] balog:
Thanks for the advice kms.

Just wondering though. How do I reset the phone? Im aware of the reset function in the Settings/About screen, but my phone wont go past the error message, which appears just after booting (after HTC splash screen).

Cheers,

balog
[7 Mozart General] Arn1e2040:
Someone mentioned in another post hard reset is done by holding both volume buttons and tapping the power button.... Hope this helps! (Can't remember if this is correct or not, been a while since I upgraded!)
[7 Mozart General] nobspangle:
This is a good thread for potential upgraders. I'm thinking about taking the plunge. In summary from the thread looks like the options for 32GB are.

1. Sandisk class 2

2. Sandisk class 4

3. komputerbay class 6

4. adata class 2

options that have been tried without success are

1. Kingston class 4

2. lexar class 10

The other important point is that any card used in a Windows phone will be unusable anywhere else. I think this is due to the phone locking the card with a unique key. Apparently it is possible to perform a low level format on the card to erase this key using a Nokia running symbian (like an N series).

I don't fancy guinea pigging another card so I'm going to go for a Sandisk. That's what I use in all my dSLRs and they do the job there.
[7 Mozart General] kms108:
I think the phone alters the table of contents or even formats the card to new extension which is not recognized, but you can always send the card back to the manufacturer for a exchange, I did with 4 of my 32gb cards, now that I have a new phone, I have put the 8gb back into the phone, and use it as a mp3 player.
[7 Mozart General] kms108:
anyone think i should try a kingston 16GB class 10, knowing it's success rate is probably less 5% of it working, I haven't got the card yet, but thinking of buying it, as ppl may know, it's the most expensive card on the market and also the fastest. if it gets killed, i can always get a exchange, but it's the trouble in do so.

[7 Mozart General] nok_fusion:
remember that lowest the card is,better speed u'll have,wp7 do Not work like other system so class 2 is the best,you should take sandisk card,u're be sure that it Works

[7 Mozart General] kms108:
someone has mention that you can bring back alive your microsd card with a nokia N8, when the card is unusable after it's been in a windows phone.

I can confirm it does work, although it works on the N8 and C5, i'm sure it will work with most of the newer phones running on the same version symbian os, that supports microsd, but have not tried it.

the instructions.

you can put the microsd hotswap or have the phone turned off,

the phone will detect the microsd, and ask for a passwork/id (after it's been in a windows phone, the microsd will be locked, and as normal you wont have the password/id).

press cancel.

in the main menu, goto applications, and select office.

select file mgr

after you press file mgr., you will have 3 drives to choose from, the last one should be the microsd, and it should'nt show any figures of the size of the usage.

press and hold, you will have 2 options to choose from.

unlock microsd and format.

select format.

that it.

32GB Memory Upgrade - Device reboots

Hi All,

Though I give a heads up on my memory upgrade experience.

I upgraded to a kingston class 4 card which caused my phone to go into endless reboots and freezes. I took out the card and tested and found the card to be faulty.

I installed a Sandisk 32gb Class 2 and i have had no issues since then. Been about a month now.

Cheers
[7 Mozart General] termignoni:
hi guys..

i've got a Kingmax 16GB Class 10 card on my other phone, i'm thinking of swapping my Mozart with this? what do u guys think? should i or shouldn't i do it?
[7 Mozart General] kms108:
it's upto you, whether you want to try it, nobody has tried the kingmax before.
[7 Mozart General] titus1:
Mozart has a memory card slot? I thought it doesn't have.
[7 Mozart General] greghayza:
The memory card is inside the unit. It requires you to undue screws to get to the card.

[7 Mozart General] nbuk:
Hi there,

Done the upgrade, was successful, using a SanDisk 16gb class 4. However, I've encountered a problem where when I receive a phone call I can't hear the other caller unless I put the phone on speaker phone. I opened the phone up again to see if there was maybe a wire I might have disconnected by accident but to no avail. Has anyone else had this happen to them? If so how did you manage to fix it? If i've done my phone I'll just get the insurance on my phone and claim it but I thought if I could find a DIY solution it would save me time and money.

Thanks,

Neil

Hi all,

so to summarise, what memory cards and its class works on the HTC mozart? I'm going to do the operation very soon and hope to get a response. :)

Thanks!

installed Kingston class 4 16gb fine. lag when syncing with Window's Phone 7 connector for mac and transferring music though. Everything else is good though, just as my 8gb Sandisk was :)

The replacement of a new sdcard depend on WP7 version? you all do for 7.0.7004? or anyone have replaced with 7.0.73xx and work?

I need to know it depend on version or not. if yes, I will do it at 7.0.7004. and if I upgrade to the latest one, it still work fine?

I did it.

Just one problem i faced while connecting the small yellow connector I forgot to cover it with the yellow transparent cover.

But now after trying several times its OK.

Thanks too much.:D
[7 Mozart General] the_matho:
Has anyone upgraded their SD card since upgrading to the leaked Mango RTM 7720? ...or has anyone that has previously upgraded their SD card, successfully then upgraded to Mango?

Basically, I'm trying to determine whether MS has done anything in Mango to stop the SD card upgrade from working.. If not, I'll be doing it asap!

Thanks in advance...
[7 Mozart General] abrabr:
Yes. I just did it and it worked ok with one additional step. After I put the card in it said "memory card not working", which didn't happen to me last time I upgraded the card. I had to a hard reset (up and down volume buttons while off plus the power button) then it worked ok. Not sure if the error was caused by the card in question, a SanDisk 32GB class 4 - last time I did with SanDisk 16GB class 2 and didn't get that error - or the fact that I have the 7720 Mango build.
[7 Mozart General] nothingsfactory:
first of all- AWESOME work and a great guide.

gone through the photos over and over again, and i had a small observation- is it possible to cut a slot in the plastic part below the aluminium case so the SD card can be removed without taking the enrtire inside module apart? possibly an xacto knife can help here.
[7 Mozart General] kendallj:
Thank you for that - this upgrade was the second Mozart I upgraded to 32GB, - the first did not require a hard reset, so with the second one I was beginning to wonder if I had been sold a fake even though bought from the same supplier as the first. Your instructions did the trick. Thanks! :)
[7 Mozart General] stryker09:
I just asked the HTC guys to upgrade it for me when I sent it in for a warranty claim. They said they can do it. Still waiting on them to call me back for details though.

8GB > 16GB.

Will be back with more info once they get back to me.
[7 Mozart General] tenchu_712:
i have mozart 16gb

how can I know if my phone has upgraded sd card by seller??
[7 Mozart General] kms108:
only a few countries have the 16gb version, or if a service provider have some special arrangement with HTC for the request, otherwise no brand new unit will have 16GB, unless the seller DIY it themselves, but this will officially void the warranty.

go into settings to check the size and the box should also state the size, if that answers your question.
[7 Mozart General] stryker09:
narp. they said it wasnt possible to upgrade it. though here we get the 16GB HD7 instead of the 8GB other countries get. just wondering why HTC didnt go for a similar setup with the Mozart. :/

Ultra SDHC ?

Hi,

You told essentially on SDHC Sandisk Card. Is there anyine tried Ultra SDHC Card, categorized as Class 6 : sandisk.com/products/mobile1-memory-products/ultra-microsdhc-memory-card

Sandisk explain that theses SD Card are 30Mb/s .... :) Interesting for our favorites Mozart ;)

Thank you for your sharing,

Alex
[7 Mozart General] Arqzarg:
Protest Transcend 32GB class 4.

conclusions:

-after installing the card and SR a long time (10 min) was sweep, but in principle it is logical axis (32GB instead of 8GB striates standard card)

-when you restart the body slightly retarding, and when connected to the BB freezes at 10-15sec. M.b checks or indexed memory

-the whole works very quickly, but it m.b for firewood because the firmware is collected on the basis of RUU_Mozart_S_HTC_Europe_5.01.401.04_5.71.09.02a_22 .51.50 _RELEASE

PS: how to unlock the old card?
[7 Mozart General] ludeunlimited:
Sandisk 16GB ultra works! fast and nice!

job done in 15 minutes with cleaning the phones inside, nice tip!!
[7 Mozart General] kms108:
you wont get 30 mb/s on the mozart, or on any phone, to get 30 mb/s the device must support UHS 1/I, and no phone on the market supports UHS 1/I.

with UHS

write 7.7-8 mb/s

read 38mb/s

without UHS (normal SD/SDHC/SDXC spec)

write 7.7-8mb/s

read 18mb/s

these readings where obtained on my pc and not the phone, on a phone the speed will be greatly reduced.

---------- Post added at 10:47 PM ---------- Previous post was at 10:41 PM ----------

if you want a faster card consider the toshiba premiugate 16GB class 10:

with UHS1/I

write 19 mb/s (stated 20mb/s)

read 38-39 mb/s (stated 40mb/s)

without UHS1/I

write 14-15mb/s

read 21-22mb/s

if you intend to use this card for the mozart it's 50/50 chance, toshiba/kingston has a high fail rate in wp7.
[7 Mozart General] bazza155:
Very nice guide have used it to repair some phones and I've had a real go at installing a larger capacity SD Card into my Mozart. Without success whatsoever. All 4 cards were geniune SanDisk Class 4, 2 x 16GB and 2 x 32GB.

The cards install perfectly, they even keep data but the phone lags a lot, has performance issues and takes at least 2x as long to install applications. I've end tried with 1 of the 16GB having the same partition that the original 8GB has and that didn't work. (FAT32, 4096 byte)

I've been looking around a lot and have not found any class 2 cards available. Has anyone had any luck with any SD cards recently? What cards have worked for you?
[7 Mozart General] ThomasRK:
Yes I did a couple of weeks ago, I bought the 32Gb from Play.com, SDSDQM-032G-B35, everything went soothly after hard reset, works very well, paid GBP 32.89, but see it is now down to GBP 27.02
[7 Mozart General] kms108:
actually, sandisk class 2-4 and adata class 2-4 works the best, I haven't had the lag, you can install the card, it should detect and read the card, for the mozart to fully intergrate the card with the system, you can do a master reset by holding volume up and down them press the power on (i think, i dont have the phone anymore).
[7 Mozart General] BartLuke94:
It's too difficult :(
[7 Mozart General] bazza155:
That is the exact one I purchased too, it worked, showed up as 32GB but there was a problem with it's performance. After the hard reset, it took about 6 minutes (usually less than a minute) to install applications on the setup process. Then it would be slow installing any application and would randomly go fast and slow. Reading was less problematic.

---------- Post added at 12:31 AM ---------- Previous post was at 12:30 AM ----------

Yeah, it was my understanding that SanDisk work best, but now thinking the class 4's I had just had poor random write speeds. So started to look for Class 2, but you simply can't get them new anymore.
[7 Mozart General] busaunit:
Ok just installed a sandisk 32 class 4 sd card in my phone. i had to do a hard reset but it has been fine since, no lag or bugs.

Here is a tip i found as i was installing the sd card to make it easier and faster. it took me 10mins if that.

Use tweezers to remove and install old and new sd card.I used a small screw driver to lift the side of the case up to expose the sd card then just pulled it out. same process for install.

hope that saves you some time.
[7 Mozart General] i9o:
no restore to previous backup

Keep in mind that after upgrading uSD you will not be able to restore your phone to a previous backup. The restore process looks and compares the size of your destination drive with that one of the backup. If these two are not the same, the restore process hangs and does not complete.

It happened to me after upgrading to 32 GB and then wanting to restore to NoDo to downgrade my SPL.

[7 Mozart General] abhilaksh:
hi, well, if you're free over the weekend, I'll do it for you. I'll get the screwdrivers, you get the card and phone. Mine lags like anything, so I just want to check whether yours will too. If it doesn't, I'm going to make you tell me where you got the card from.

But will it surly work?

anyone any idea, or it is just trial and error type of thing?
[7 Mozart General] kms108:
there is 50/50 chance of it work and not working, go for a sandisk class 2 or 4, chance are it will work, as the class wont make much of a differences.

also the mozart has only one security sticker on one of the screws, just use a pin and carefully remove it, and you wont void the warranty.
