[Windows Phone 7 Q&A, Help & Troubleshooting] Quicksilver4648:
GenkaiMade gave his version which is correct but I thought I would explain it my way.

Take your average memory card and device. What are some of the default expectations you have when using one?

1) You should be able to get any MicroSD card on the market and be able to put it into your phone with it working.

2) You should be able to remove the memory card from the device and put it in a different device (such as another phone or PC) and have it still work like normally.

The problem with Windows Phone 7 is that it breaks these two rules.

1) Many of the higher rated MicroSD card flat-out don't work on WP7. This is because of the method WP7 uses to read/write to memory card. You can find more specific details on why this is but I will just keep it simple. There are many user-created lists which list which MicroSD cards do work with WP7.

2) You can NOT hot-swap your memory card once it is inserted into phone. Why? SD stands for Secure Digital which means there is a security aspect capable on the card. Microsoft takes advantage of this in WP7. Once you put your new card in your phone automatically reformats and locks it down. If you then take out the card and place it in another phone or a PC it will not be recognized, almost as if it is invisible. And the worst part, there is nothing* you can do about it. Once you pair a memory card and WP7 phone they are joined for life.

Why does this suck? If you buy a 8GB card now you simply can't upgrade to a 16/32Gb one down the road without losing all of your data and having a useless MicroSD card. The old card would become a better Frisbee than data storage device. This is why most WP7 phones don't let the users have access to the memory card. Microsoft knew this would happen and thus pushed manufacturers to not have the card easily accessible. There is even much talk that the memory card in the Samsung Focus was meant to be glued to the phone to prevent swapping but somewhere along the line that idea was scrapped.

* Note: Technically there is ONE thing you can do. If you own or have access to a Nokia N8 phone it can read the locked down MicroSD card and reformat to something any device can recognize. Essentially undo the problem. But how many people have easy access to one? The answer, almost nobody.
[Windows Phone 7 Q&A, Help & Troubleshooting] N8ter:
You're wrong. It has nothing to do with what you said. Lol @ breaking rules. They aren't breaking anything...

SD Card DRM is in the spec, it is only given to people who license it. That's what WP7 uses. It's locks down the storage system with a DRM key and that's why other devices (barring Nokias) can't see it - most SD Card clients don't support SD Card DRM.

Nokia (Symbian, and maybe Maemo, but I'm unsure on that) is the only other mobile OS that supports it, and that's why it can reformat the card (but cannot read any data on it, of course, since it doesn't have the decryption key). When you power on the phone, the WP7 pre-boot environment unlocks the card via a key on the device the same way you unlock an encrypted system drive on a PC. If a device cannot supply this key, they cannot mount the card.

If you swap the card, you have to hard reset the device because the storage is spanned and the decryption key on the device no longer corresponds to the SD card in the device (but due to spanned storage the device would malfunction even if it were to boot up). The new card is encrypted and added to the pool on a hard reset, and the [new] key is put on the device so that it can be mounted when the device is powered on.

It's pretty damn simple, and has been written in plain English in many threads; yet people still FAIL to understand it.

Have you ever thought there must be a reason why they call them SECURE Digital Cards? Or did you think Secure = taking it out one device and just plugging it into the other and taking the data off of it?

The Storage in WP7 was never meant to be swappable. Microsoft has always said it would not be. It's your own business if you want to play around swapping cards like Russian Roulette.

As far as which work with WP7. It requires higher Random I/O speeds than most SD Cards provide, and that doesn't correspond to Class Type. Also, a card can work fine for sometimes weeks at a time and then start to fail, so replacing it yourself is at your own risk.

And most manufacturers and carriers will void you warranty if you mess with the SD Card.
[Windows Phone 7 Q&A, Help & Troubleshooting] doministry:
In that respect using memory cards is nonsense on WP7.

If you cannot do what you want with this, what was a rule and still is a rule on the market today,

they should just build devices with inbuilt memory like iPhone and don't talk about memory cards anymore. That would be simple.

Current situation is a mess.
[Windows Phone 7 Q&A, Help & Troubleshooting] williammel:
So what cards are compatible now? I Googled it and the first response was 'San Disk Pulls WP7 compatible memory cards' and I figured that wasn't a good sign.
[Windows Phone 7 Q&A, Help & Troubleshooting] The Gate Keeper:
they only pulled it because MS wants to do official testing and release an official list.

[Windows Phone 7 Q&A, Help & Troubleshooting] Quicksilver4648:
It was a figure of speech. I know Microsoft didn't break any real "rules". This is what I posted:

When I said "rules" I implied "expectations". Microsoft did nothing wrong, outside of communicating with the end users, with how WP7 manages MicroSD cards.

And I clearly know why certain MicroSD cards will or wont work. I just didn't feel like explaining it because it would take a lot of time.
[Windows Phone 7 Q&A, Help & Troubleshooting] N8ter:
It's time to start expecting people to use these technologies in a secure manner.

The media industry does not support platforms that leave them open to be attacked by software pirates.

Information is power, and no one likes their info stolen.

There are many reasons.

iOS phones encrypt their storate. And the reason why they don't support external storage cards is probably the same reason why Microsoft uses the SD-DRM and encrypts the WP7 storage.

I don't know how Symbian handles its storage, but I'm pretty sure that OS at least supports Encrypting the file system on SD cards. It supports pretty much everything ele.
[Windows Phone 7 Q&A, Help & Troubleshooting] JETninja:
I just got 2 Focus's for the Wife and I. Using the SD card sticky in the Focus forum here as a general help, I purchased a PNY 8Gb C4 for the Wifes, and a Patriot 16Gb C2 for mine (Frys, and the Patroit was the last one in the store from the Display! No one buys C2 anymore).

The back overlay on both devices mentions memory cards, and quick startup quide shows you how to install them and what happens if you remove them.

I put the Cards in last night (phones just arrived yesterday), formatted (hold the Power/Camera/Vol Down at the same time, answer questions) and in a few seconds each system was formated. Both are working fine right now.

Right now though doesn't mean much, many in the SD thread are having issues after several weeks, though it seems it more prevalent with the 32Gb cards. YMMV...
[Windows Phone 7 Q&A, Help & Troubleshooting] FL5:
What I find goofy about the whole thing is that it has been stated that 7 needs random read/write, which is not measured by class rating, and can vary even within the same type of card, but very few people have posted numbers showing that they tested their cards at all before gleefully sacrificing them to the hungry maw of the Focus. Seriously guys, do more testing and post more numbers before rendering your cards unreadable to a PC. It'll help us all to better understand what works and what doesn't.
[Windows Phone 7 Q&A, Help & Troubleshooting] sputtle:
This bites.. I always knew that the card inside the wp7 was secured, but I always had faith in the power of this forum. Especially in recovery situations. Now I have lost a lot of irreplaceable data, like dozens of pictures of my young child. :( It seems I had a little too much faith.

Thank you for this information. it was very helpful. I have already moved away from Windows phones to android, and am going to start using nandroid. Hopefully this won't happen again.
[EVO 4G Q&A, Help & Troubleshooting] smkcbs10:
I have a somewhat unique situation that I haven't been able to peace together after 6 days of searching threads. Any insight would be greatly appreciated!!

My elderly mother bought an EVO recently after I bought one and some idiot talked her into running the 3.30 RUU on an EVO with software 3.26.651.6, baseband 2.15.00.07.28, and hardware ver 3. This also upgraded her HBOOT to ver 2.02. From my thread searching, it seems that 3.30 isn't intended for EVO's with HW ver 3 and may impact the phone's performance and/or battery life. I do believe that there was an OTA for her phone for 3.29.651.5.

I am wondering if it is possible to downgrade her HBOOT and sw back to 3.26.651.6 and the corresponding HBOOT version? I would then want to apply the OTA to update to 3.29.651.5, where she should be. She NEEDS to have a stock phone :D. From searching threads it appears that I need to root her phone using the 'like a boss" method and then run the RUU 3.26.651.6. However, I am unable to find the stock 3.26 recovery img needed. I do have the stock 3.30 recovery img but am reluctant to use a different recovery img.

Help please, if you can!
[EVO 4G Q&A, Help & Troubleshooting] smkcbs10:
A little direction if you can...

Anyone? Just looking for a little direction here. Also, trying to follow the rules and keep this out of the dev section...

Not a noob to rooting, just to the EVO. Rooted my old hero and flashed a few diff roms...just want to make sure I have the right info and am prepared before I start rooting the phone. I really have searched MANY threads and I feel confident about rooting the phone via "Like a boss" and illogos's updates but I didn't find anything about successfully un-rooting to a pre 3.30 software version.

Can I just run the RUU for 3.26xxx after rooting? I'm assuming that will be fine with S-Off and an older hboot.

Go to amazon and search for the brand Arkon. Its about $15. It comes with dashboard and ac vent mounts. Its much better than the crap my sister bought off ebay. It fits my vibrant with crappy silicon case nicely.
[HD2 Windows Mobile 6.5 Themes and Apps] wigwam12:
I blame mskip for this!

There I was with my stock HD2 and enjoying a really smart phone for 8 months.

Then I decided to look for an update to quicklinks to work with the 3.14 ROM and he introduced me to the idea!

So I went from CHT 1.85 to CHT2:D

And then I saw all the fantastic homescreens.:eek:

So I have installed so far:

Brian's Taskbar (gfreek edition) - it was my little boy's call to go with this over Diniks:D

Rat_2556's coloured notifications

I see some things by Touch of Glass that I like; many things by Dinik that I like and Franwella's Coloured Comms Manager that I like.

(I still have not found a Slider for the Manilla/Sense that I like yet)

Could someone please confirm that there will be no problem to "mix and match" different things from these different people eg (say) the TOG dialer and the Dinik keyboard etc?

Could some one point me to a nice tweak to the Calendar appearance as well please?

Thanks:cool:
[HD2 Windows Mobile 6.5 Themes and Apps] Awassenaar:
Mixing things won't cause problems with your device :). But with every custom made item you can't guarantee that it will work 100% of the time. But then you just uninstall that item. There will be no permanent damage! And it doesn't matter if you install things made by different people.

Don't know about a nice calender mod though...
[HD2 Windows Mobile 6.5 Themes and Apps] Marct77:
you could try dinik mods by you thread,jsmmcabe has done some calendar mods

[HD2 Windows Mobile 6.5 Themes and Apps] kurt-willems:
If you are still on stock ROM the only thing that you must look fore is that your skins (the one you will install) match with WM 6.5

Ow, don't forget to install "sdkcertsnew2015" its mostly needed on the lasts builds.

[Galaxy S I9000 General] thug_life_inc:
Hello,

Its the time I have to ask dumb questions (maybe) even if I tried searching for the same issue.

Which is:

I am unable to select GSM auto (PRL) from phone settings, following these instructions:

1) Goto dialer and dial *#*#4636#*#* (DO NOT press send)

wait a second and you will get the test menu.

2) In the test menu choose 'Phone Information'

3) scroll down and choose on the first drop down - GSM auto (PRL)

I can select the 'GSM auto (PRL)' menu but it automatically reverts back.

More info about my SGS: runing Doc's ROM 9.0.1 BUJP8, rooted, speedmod kernel 256MHz (Samsung default), unbranded European SGS with MultiCSC

Any help/info on this will be highly appreciated as I know that its quite possible for this setting to save our SGS battery life (I am not the only one experiencing the issue).

Thank you in advance.

I do not believe its a custom ROM issue as I have a friend with stock JP7 rom, no lagfix having the exact same issue.

[Legend General] xxbeanxx:
Hey everyone. I've been having issues with my data connection and I'm trying to figure out what is causing it. I am using CM 6.1 RC2 and I have the updated radio from the vodafone rom.

For example, when I enter the market, about 50% of the time I get a network error after resuming from sleep and have to click retry once or twice before I can do anything. The data connection is just not reliable anymore (yet before this issue it always was).

I'm just wondering if there is an issue with RC2 of CM or if it is the radio update causing this. Can anyone comment?
[Legend General] rickb928:
I'm not sure this would be related, but after flashing 6.1.0 on my Dream I find it stuck in EDGE occasionally, usually when in the car or after, and in places where I get solid HSPA before 6.1.0. So far, I have to reboot to get HSPA (or 3G) back. There are some notes on updated radio and a kernel to address some radio problems, is anyone else seeing this?
[Legend General] partenov:
Hi,

I have similar problem. My legend is not with the latest radio or kernel.

The specs are:

CyanogenMod Legend 6.1

Radio: 7.05.35.26

Kernel: 2.6.29.6

The problem that I see is: During the night when the phone is not used it looses the data connection. When I turn it on in the morning there are no mobile network indicators. I have to reset the network ( by airplane mode or reboot) ot get back my data connection.

During the day there are no problems.

I suspect that this happens because of the weak 3G signal in my area. However I use auto setting. ( 2G and 3G)

When I was with stock ROM I haven't such issues with dead data connection during long sleep.

EDIT: I have just upgraded the radio to 7.08.35.21. I will check how it works tonight. :)

[Legend General] Catnap:
I've been having some data issues too, I've had to go to and from Flight Mode in order to get any form of connection (data OR telephone) back, and I occasionally get stuck on GPRS. Toggling "use only 2G networks", waiting for the data to come back and then toggling it off again gets EDGE or H back, but it's pretty flaky compared to RC1 and the older radio.
[Legend General] senm:
I think i have the same or similar problem.

It looks like I have a data connection (3g is showing and signal strength is almost full). But when i try to connect to facebook, browser or somthing else what needs a connection it cant connect.

I have a taskkiller running when i kill all the task 90% of the time i will get a connection.

I have the same programs on my phone when i used 2.1 and with 2.1 I never had this problem.

Strangely enough it seems like mine is working much better lately. Maybe there was something up with Bell. I haven't gotten the connection error in days.

[Android Software/Hacking General [Developers Only]] clpirate:
Hi all, first time post so I hope I've put it in the right place!

Problem I have is that I can't seem to update the YouTube app on my Desire,

Currently running the OpenDesire ROM (4.0.36) (Phone is rooted)

I try to update or/and install from the App store and I get installation unsuccessful. I've done a bit of searching and a lot of people have had success by loading Titanium Backup, uninstalling the app, re-booting and then installing from the app store. This doesn't work for me as when I re-boot, for some reason the app and the .apk file is back there.

This isn't a major drama, just mildly annoying I guess so if anyone can help, I'd be very appreciative.

[Desire Q&A, Help & Troubleshooting] Lomax01:
You won't necessaily have s-off, or nand unlocked, it depends on what phone you have for this to work using Unrevoked. There are other methods available if you wish to do this.

Have you actually tried installing an app that requires root access, like Setcpu or Titanium Backup, to see if it actually works?
[Desire Q&A, Help & Troubleshooting] idasein:
I got an htc desire a month ago and got errors when I tried rooting with unrevoked. It turned out the hboot version was too recent (0.93) so I had to downgrade to 0.83 using this guide: xdaforums.com/showthread.php?t=768256

It actually downgrades your phone to android 2.1 with Sense, but after that you can root your phone normally and then flash the Rom to any 2.2 Rom you want. It's a bit involved but the only way I could get root.

I wrote a quick guide for this before, which I'm reposting below. You can skip step 1 since it sounds like your phone is not branded.

Step 1:

Get an extra MicroSD card (2gig or whatever) and create a goldcard. You ONLY need this because if your phone is branded (eg. by a carrier... if any other names come up during boot, your phone is branded) and this is part of getting rid of that. If your phone is not branded, skip to step 2. Find out how here: android.modaco.com/content/general-discussion/305672/creating-a-goldcard/#entry1233023

Tip: you don't need an microSD card reader. You can format the microSD card in your phone by connecting your phone as a USB drive, and right-clicking the drive and formating. It MUST be FAT32 format, NOT FAT, so do it from the computer controls, not on the phone itself (because the phone itself does it in FAT format)

Step 2:

With your goldcard in your phone, you can now downgrade to Android 2.1. This kills two birds with one stone. A. It removes any branding from your phone and B. Lowers your hboot from higher versions to 0.83 which makes it possible to root your phone. Instructions here:

xdaforums.com/showthread.php?t=768256

Tip: if it fails the first time (as mine did) and it can't find the zip file at the end, make sure your goldcard was FAT32.

Now your phone will be running HTC Sense 2.1 unbranded. The next two steps will allow you to put any of the Froyo versions (with Sense or without, your choice) on your phone.

Step 3:

Root your phone with UnrEVOked. Instructions here:

rootmydroid.co.uk/guides/general/howto-root-your-htc-desire-wildfire-evo-incredible-with-unrevoked/

Tip: His instructions are great. His download pages are horrible, but they work eventually, just keep clicking.

Step 4:

Install any of the custom Android ROMs available. Instructions are also found on the above link for rooting the phone.

You can choose from any of the ROMs listed here: xdaforums.com/showthread.php?t=809328

I went with DeFroST, which is a nice Android ROM without Sense, since Android is better off on it's own, IMO.

Tip: If you don't have an MicroSD card reader, make sure you put the ROM's zip file on your MicroSD before you wipe your phone (Pt. 3, point 4 in the guide).
[Desire Q&A, Help & Troubleshooting] supasye:
wow thanks for that..

my phone is rooted, i just want s-off.. but i have read that unrevoked doesnt work for gsm phones, which is what i have..

so i tried alpharev, which seems to be working for most people, but when i tried it using virtualbox, it tells me that i have a cdma phone, and to go back when i know what im doing or something like that..

i 100% have a gsm phone... why do i get this??
