So I have the the Sprint HTC Arrive (aka. the HD7 Pro) and I have taken it apart to see where the memory is located at. If there was a slot where the memory card could be ejected from, it would right in between the +/- Volume Buttons. Just remember that opening your phone will void your warranty, but here are the pictures I took. It has a 16GB Class 4 Sandisk micro SD card. The slot is not spring loaded so to remove the memory card you just pull it out. I will be testing out if a 32GB Class 10 or Class 2 will work perfectly on it since its running a 16GB Class 4.....

added the pics in a zip file for closer inspection.....

Please keep us updated!

Great find and post further investigation needed. Pls keep us posted.
[HTC 7 Pro] Savage1969:
Pardon my stupidity (still on my first cup of Joe) but would the current classes of 32GB cards still be slower spec'd than the 16GB? I'm having a brain fart and can't remember, or I would swap mine out right now just for grins. I wouldn't have an issue hard resetting right now anyway...
[HTC 7 Pro] 92GTA:
Where are the additional pics? I have all my screws out but can't seem to get the plastic cover off the back!

EDIT: Got it!
[HTC 7 Pro] quantum3:
please keep us updated...I have the arrive also and I would love to upgrade to 32gb!
[HTC 7 Pro] exilkubaner:
as far as i know, the memory card on the 7 pro is close to the speaker, so they must have changed the layout a little. doesn't really make a difference though
[HTC 7 Pro] supercain:
Can you post a step by step.

Can you post a step by step how to do this. When you figure it out. I would like more memory in my Arrive. Thank.:rolleyes:
[HTC 7 Pro] theclueless:
1. remove the 4 small screws under the battery cover (one on the top left is under a black warranty sticker)

2. remove the odd ball big screw on the lower left; just use a flat-head and slowly turn about 45degree at a time, it is pretty easy

3. use your fingernails or tools to take out the plastic cover (it only actually covers the side of the phone), you will find another cover with 6 more screws that actually covers the back of the phone

4. remove those screws, and the lift the back cover (unlike the side cover, this one just sits on top, and not snapped onto anything)

5. the sdcard is on the right side, next to where the volume buttons are

6. to remove the sdcard, you will need to peel the yellow tape up enough so it is no longer sticking to the sdcard, then just wiggle it out (no eject mechanism)

7. no pictures, the phone is my camera :mad:

Instructions

I was about to post the instructions but you got it just right, was really easy to take apart. I have a 32GB Sandisk Class 2 and a 32GB Lexar Class 10 tried both and both are working fine.... stuck with the Lexar and good so far! I did feel that loading apps or music with the Lexar Class 10 was a bit faster.
[HTC 7 Pro] supercain:
Thank the clueless one. Cool.
[HTC 7 Pro] adihere:
Did you have to hard reset after installing the card? Anyone?? Thanks in advance!
[HTC 7 Pro] goulav:
what about side loading music to the sd card?

does the phone recognize it if it's on the card but not loaded from zune?

[HTC 7 Pro] eduncan911:
I'm now w/32 GB in my HTC Arrive. I'll post a blog post about it soon enough with better pics. Until then, a few tips:

* Do a hard reset on your device before you begin. Goto Settings -> About and click Reset. Don't take the chance of an existing install corrupting (WP7 requires a hard reset when changing the flash card).

* Use a medium flat-head screw driver at a sharp 45 to 55 degree angle to get a bit on that tri-wing screw on the back and turn it.

* Remember, there are 4 screws you need to remove. One of them is hidden under a small black label. This is how the manufacturer knows that you have tampered with the device. You simply push down with your tiny phillips, and your screw driver will melt through and you can turn it.

* Let your fingernails grow for about a week. Use your thumb and start at the keyboard area to pop things loose. Work your way around to where the display attachs. Easy peasy.

Please note that I had issues at first with this upgrade. I'm now ordering the Sandisk 32 GB Class 4 card now (Class 2 are sold as Class 4).

See attached pics.
[HTC 7 Pro] ScottSUmmers:
I'm thinking of doing this upgrade. Would someone that has done it tell me if there truly is an increase in performance or if the hardware of phone still bottlenecks the read and write speeds? Thanks.
[HTC 7 Pro] eduncan911:
You don't do it for an increase in performance. You do it for the increase in size.

Stick to only the Sandisk microSDHC 32 GB Class 4. Nothing else.

The important part is random access times, not read/write. Makers sacrafice random access times in order to increase read/write (e.g. class).

My Wintect Class 10 is such a card. Random access times is horrible, but it does 20 MB/s as promised. I've ordered a Sandisk 32 GB card now.
[HTC 7 Pro] klecka27:
So...pardon the noob in me, but if we shut off and reset the phone before swapping out the card will we lose the os? Or is it built into other memory? Is there anything at all I will need to do regarding the wp7 os?
[HTC 7 Pro] eduncan911:
Yes, you will loose the OS.

WP7 uses both internal memory and the card formatted in a special "extended" way. Once you change the card, even for the same size card, the OS will freak out and require a "Reset":

Press power button while holding VOLUP and VOLDOWN at the same time. You'll get a white screen, where it will instruct you to press VOLDOWN to reset to factory.

With the Gmail sync of calendar and contacts, SkyDrive to upload all of my photos-on-the-phone too automatically, I have reset my phone like a dozen times now trying out different memory cards. It's no biggie. I setup the syncs again and BAM, I got my info back. Just, you loose SMS history. NO biggie for me.
[HTC 7 Pro] eduncan911:
SUCCESS: SandDisk 32 GB microSDHC Class 2

After my failed Wintec 32 GB Class 10 card, I am here to report SUCCESS in using the following card in my HTC Arrive:

SandDisk 32 GB microSDHC Class 2

Don't bother with the Class 2/4 rating. I still measured about the same performance as the stock Sandisk 16 GB microSDHC Class 4 it came with. Seek time is important, and matched. Just the write speed dipped down to 3.5 MB/s during some tests, hence the CLass 2 rating instead of Class 4. FYI, the OEM class 4 card only wrore at 4.5 MB/s. No big deal!
[HTC 7 Pro] LayneRobinson:
That's actually a feature I would like! :)

Seriously, though.....where's my delete all for message history or phone calls? I would periodically clean out my messages on my WM6 phone because it actually would go longer without locking up....not that I've had a lock-up with my Arrive, but I also don't need all of that history.
[HTC 7 Pro] eduncan911:
When viewing all threads in WP7 SMS, you can press-n-hold each thread to "Delete Conversation". Seriously, how many "conversations" do you have anyways? Even 15 wouldn't be a big deal.

But no, there is no delete all convos.
[HTC 7 Pro] klecka27:
Alright, follow up question. What I meant was...will I have to find a ROM of the sprint radio in order to re-install WP7 or does it reset itself and reinstall the OS when you start it up?
[HTC 7 Pro] eduncan911:
Nope, you will not need to find any ROM to load. Factory Resets sets it back to the way it was shipped from Sprint, with the whole "Welcome to Windows Phone" setup process.

Try this:

1. Do you have your photos syncing to SkyDrive? If not, they should be on your Zune software/computer anyways by default settings. If so, don't worry - they are still there (just have to re-sync them from teh Zune software).

2. Did you sign up/in with your Windows Live account when you setup your phone? If so, by default your contacts are backed up into that account. Actually, by default, all contacts must belong to an external account (unless you pop only, which is hard to do).

Verify your contacts are sync'd by going into the settings of each mail account you have, and check "Sync Settings" which should show "Contacts" checked.

3. Any applications you installed/purchased will still be active. Just write them down, so you can find and install them again after the reset using the Zune software. What's odd is, some apps are automatically installed after I reset, and others I still have to go find and install again. Odd.

And you have to forget about saving the SMS. Outside of that, everything is saved and you can reset. It's not as painful as it sounds, there's not a lot of customizations you can do anyways on WP7. After a few resets, it becomes 2nd nature to setup the sounds and colors and alike in about 5 minutes.

OT:

Technically, the radio is different firmware - and not even touched by this process. Sprint updates the radio's firmware periodically in the background without your knowledge. Been like this forever it seems. That's why when you load a custom ROM on other phones, you loose the auto-updating by the carrier for the radio firmware. Why do carriers update the radios? To keep up to date on protocol versions, tower handling, etc.

As for the WP7, there are no hacks (yet) for the Sprint ROM nor the radios anyways, at this time.

Just did my arrive :)

Purchased phone on release day and my phone actually had a class 4 16gb sandisk i think most have a class 2 from what i have seen find that strange. Replaced it with a class 4 sandisk 32gb. Thank you to OP your instructions were great
[HTC 7 Pro] htakahasyd5:
HD7 Pro is different!

I replaced SD card of HD7 Pro today. Please be noted that there are 7 more screws after removing its plastic cover instead of 6 more scriews. Also, the SD card is not on the right side, but behind the SIM holder.:)

[HTC 7 Pro] htakahasyd5:
Thank you. I think we should change this thread title appropriately. Can mod delete "(HD7 Pro)"? ;)
[HTC 7 Pro] eduncan911:
No. The microSDHC specification only goes to a maximum of 32 GB.

There is a newer microSDXC specification that technically allows for up to 2 TB (yes, terabytes) on those tiny cards (if the manufacturers can do it).

The problem is the physical slots are different between a microSDHC and microSDXC. So, until phone manufacturers start making phones with microSDXC, you are stuck with a 32 GB max limit.
[HTC 7 Pro] Oditius:
Anyone try a ADATA 32gb class 4 card? Reason I ask is I have one. I use the Weink on my android, but it crashed all the time. Tech told me most phones are rated for class 4 or below. So I bought the Adata and it has been working great in my Android. So I was wondering if I could use that instead of paying another $60 for another card.
[HTC 7 Pro] Oditius:
Where is that 4th screw? I found the 3 little ones.

Update: Took a magnifying glass and found the sticker that said VOID. So I presume that it is under that.
[HTC 7 Pro] Oditius:
Since this is my 3rd post in a row, I guess I am officially talking to myself. :rolleyes: But my 7 Pro is running great with the ADATA Class 4 32GB card in it. Thanks to OniKyanAE86 and the rest for posting this. :D
[HTC 7 Pro] Oditius:
OK, everything works great, but how do I format the card that was in the 7 Pro? I tried to do it in the multi-card reader in my laptop. i tried the reader in my usb port, I even stuck it in my android tablet. But nothing seems to find it. :confused:
[HTC 7 Pro] ScottSUmmers:
I believe if you hold down on the volume rocker when you turn on your phone it'll give you the option of formatting your card, by pushing up on the volume rocker or doing a hard reset of the OS by pushing down.
[HTC 7 Pro] Oditius:
Thanks for the suggestion, but this is the 16gb I took out of my phone. For some reason my laptop doesn't see it, well it kind of does then doesn't. Of and on thing. I tried the reader, I tried two other readers, and tried a USB adapter and all the same results. In and out. So I put it in my Galaxy Tab and it wouldn't even recognize it.
[HTC 7 Pro] dxdy:
WP7 microSD cards is locked and encrypted....

if your reader see card, you can format you with Panasonic SDcard formatter and dont forget in options enable adjustable size to auto

also you can try format card in many Nokia phones or camcorders

[HTC 7 Pro] Oditius:
Thanks but the problem is the reader only see's it on and off. It has no problem with any other card, Just this one. Guess it's a wasted 16gb card... I'll just toss it in the trash, my computer doesn't see it, the GPS doesn't see it and the galaxy tab doesn't see it either. I don't have any Nokia phones.. But thanks again for trying..

maybe you find someone who have Nokia :) or just ask friends to try format card in their phones...

I am curious about whether or not a 64GB MicroSDXC Card will work in my HTC Arrive.

Has anyone even tried to put it in the HTC Arrive yet? If anyone has, I would like to know what happened.

From what I've read on quite a few web sites, the card works in Android phones. Even the ones from HTC.

But what I've not read anywhere is whether or not they work in any Windows Phone 7 phones like the HTC Arrive.

If anyone has a 64GB MicroSDXC card that's going to try to install it, PLEASE let us ALL here know the results.
[HTC 7 Pro] Oditius:
If you buy me one, I will put it in my HTC 7 Pro. I mean if it will work in one Win 7 phone, it will probably work in all. :D

I upgraded my Sprint HTC Arrive recently to 32GB and have had no problems so far. Here is the card that I purchased:

Samsung 32 GB microSDHC Class 10

I also documented the procedure. Here's a link to the guide I put together (link is off-site due to XDA attachment size restrictions):

http://dautrich-multimedia.com/blog/wp-content/uploads/2012/05/HTC-Arrive-Storage-Upgrade-Guide.pdf
[HTC 7 Pro] Loco5150:
Well this is not completely true.

I took out the SanDisk 8gb class 4 card and put in SanDisk 16gb calss 2 card.

The card started to cause some random resets for example when opening the kb and starting to type sms really quick. Problems started always to arise about 4 days after hardreset. Also after a while I couldnt start programs anymore.

I changed my card to this Samsung 32gb class 10 card everyone seems to have good results with and the speed difference of the device is just huge. With this class 10 card the device is faster in every task. Also no resets or crashes after the change.
[HTC 7 Pro] KathiKibbles:
Broken flash?

I looked to see if I could follow the directions, but now it seems the flash on my camera doesn't work. :eek:

Didn't happen until a few weeks after I had opened the case (and I had flashed a new ROM). I did use the camera flash soon after I opened the case to take some pictures, but it's the only thing that I can think of that might have caused the problem.

From what I can tell, I shouldn't have hit it directly in any way, but wondering if anyone else has had this problem.

Thanks!

Hello all. I have an HTC Arrive that since the day i got it has been 'slower' than it should be. My wife and i got the same phones and her phone continues to zip to this day, where my phone even after unlocking and flashing LEADs ROM, still is slower. When i first got the phone the homescreen was skippy and laggy right out of the box, but i figured i just needed to update it to Mango.. well Mango did improve it some, from skippy and laggy to smoother but slow. I've always had little issues here and there of apps just closing or not opening at all on first attempt. One time i was using the Bank of America app and went to back out of it and my homescreen went scrambled and doubled, even the apps list was doubled. It took a reboot before it straightened out, but I never seen anything like it before.

My question is, does it sound like I have a faulty sdcard, or a faulty phone? I am happy with the custom ROM i loaded, and before I get too comfortable I'd like to replace the card if suggested to me.

p.s. this is my second Arrive, when we first got our phones, my original one was fast like my wife's, but the handset speaker blew in it after about a week and it had a few dead pixels so i RMA'd it and got this one.

thanks in advance for replies!

After drinking and decided to try out something random. I can confirm the san disk ultra (the grey and red one) 64gb sd card works in this device with no lag and full storage space. Only had to do hard reset - vol up and down and power button. Then down down.

It is a really good setup if you are planning on the increase storage for music or porn.

Sandisk 64GB microSDXC success (so far)

First-time poster, long-time lurker ...

I bought a "new" HTC Arrive via eBay a week ago, with the expectation of trying memory upgrades and various ROMs before activating it. After a week of Mango (stock 7.5 7720, I think) ... and the arrival of my new Sandisk 64GB microSDXC over the weekend, I have successfully upgrade the device to 64GB and followed that up with an upgrade to WP7.8. I'm new to the WP7 line, but I haven't observed any issues thus far. I intend to get more familiar with the device over the next week before attempting one of the fine ROMs posted here.

I ordered this Amazon SKU B007WTAJTO

amazon(dot)com gp product B007WTAJTO

I don't know if there are any screenshot apps I could use to capture the "About T7575 screens" or if there are any worthwhile benchmarks.

Thanks to those who posted instructions and insights earlier in this thread.

Interesting to see report of SDHX compatible.

After force updated to 7.8, I saw some problems. I have difficulty to pin point to the problem, but it has some problem with the radio(might be Sprint, can't tell) and wifi sometime stuck when I tried to switch it on. weather app crash when I pinned the dynamic location, I had to unpin, and then delete all the related locations. Alarm app locked up until I deleted all alarms and setup new ones... I do hope they can release an official update, but for the size of the existing product, I doubt they will.

Successful root to new leadpoizon 7.8

This morning, I successfully rooted my Arrive and promptly loaded the leadpoizon March 1 stable 7.8 ROM. No issues, other than not being able to post a note of gratitude in the appropriate development thread :laugh:. Thanks to all in this thread, the HTC Arrive Hacking Guide thread, and in the leadpoizon ROM thread. No issues with the 64GB microSDXC card. I don't know how these numbers compare, but WP Bench (Free) scores the card at mem 15.25 MB/s and stor 7.73 MB/s

Now, if I could just find an easy (and free!) way to load my contacts without going through the cloud ... Mass QR code generators, here I come.

I just bought the 64GB microSDXC card (sandisk) and while it sort of works, I just get random reboots whenever it tries to install an app, sync something from zune. it even restarted a bunch of times while i was just trying to setup my phone. so far, no love right now unless someone has any ideas why this is happening. I got the card that was described in these recent posts and ordered it directly from amazon.com, not from a third party.
[HTC 7 Pro] SUOrangeman:
Still no issues here

I haven't experienced any wierd issues to date. I still have not activated my phone, but most of the basic apps (CNN, ScoreCenter, Weather Channel) I use have been functioning fine. What ROM do you happen to be using?

I think I am experiencing the live tile issue with 7.8, but that's about the only complaint (other than directly syncing contacts and calendars without using the cloud).

Update: I just flashed to the latest leadpoison ROM and everything seems great. At least one live tile is now working that wasn't before (Weather Channel). I just wish I had done a better job backing up stuff first!

[HTC 7 Pro] unrealreality:
I'm using the stock 7.8. Sprint didn't offer an official 7.8, so I used the XDA updater to get it. Everything works fine on the stock 16GB card that came with the phone. The 64GB i used had restart issues like I said. Even trying to install an app from the store, it would almost finish installing, then freeze and restart. I'd then get "storage card error" screen. restarting it again seemed fine, but i'd have the same issues.

I pulled out the 64GB and put back in the original 16GB. After resetting it up, I have no issues, so it seems to be the card. Not sure if it's just a bad card or what.

*** Is there something on custom ROMS that allow the SDXC or 64GB card to work that I'm missing from the stock 7.8?

I think I might give it one more go and get a replacement from Amazon for a new one. If that one doesn't work, I guess I'm just not meant to have the extra space :(

Activated on Ting

After a month or so of testing/playing without cellular service, I finally activated my phone. Instead of going through Sprint, I signed up for Ting. The base plan was $6 a month with no included minutes, texts, or data. After reviewing their options, I'll barely come close to their "XS" options (500 minutes talk, 100 text, 100MB data), which will add a whopping $9 before rolling over excess from the previous month. If only I could get my wife's Blackberry over to Ting ...

Hopefully, I'll have good things to report about Ting in a month's time. Maybe I'll get to put my referral link to good use. (:

Nonetheless, he 64MB SXDC still seems to be holding up just fine. Still no usage issues to report. I just haven't been able to perform a full backup with the various tools out there.
