[Q] Would this work - Reflashing

Just had a though and wondered if anyone had tried it.
We know when we take a sim card out and boot up WP7 it boots as if it a virgin install.
So my question is if we were to reflash the phone with a second sim card can we then insert the original sim card after the install completes to save us losing all the data and settings?
Has anyone tried this?
EDIT: I meant SD Card not sim card

No replies
If anyone is going to install the new rom would it be possible that you could insert a second sim when reflashing and after the flash it complete reinsert your old original sim and see if it works and keeps your old settings?
If not it will only need a reset to reformat the original sim so nothing to lose in trying this, I would try myself but I have too much on my sim to lose at the moment and cannot try until weekend as I need my phone through the week.
Thanks

whoops, didnt mean to hit thanks! oh well, one for your collection!
from my point of view it wont work, the SIM being there or not wont make the blindest bit of difference when you flash it, the installer will wack anything on the SD card, which is the only place that could keep the data intact
if your looking for backup wait a while, Windows phone device manager will soon have a backup program built in to it, your phone will need to be unlocked as its not MS supported but other than that it should backup you data and your app data allowing you to flash to your hearts content, and keep your data.
i dont know if it will install apps again though, i suspect not, but its progress!

You got a thanks back
What I meant was, if you power down your WP7 and remover the sim the phone boots up perfectly but none of your contacts are there or emails and preferences.
If you the power down and re insert the sim your phone boots up as normal with all your settings.
So if we reflash using a different sim card the after the flash is complete, power down the phone remove the sim card and replace it with the one you were using before the reflash, would it not use the setting stored on the older sim card?
I have the manager registered so will use that when its out but this was just an idea and wondered if anyone has tried it.
(power down your phone and remove the sim and power up and you will see what my logic is )

DOH I meant SD card not sim (brain dead )

ahh, yes now that makes a lot more sense!
ill check, i plan on reflashing on sunday to update to NoDo, i need to backup all my app data first just incase so it will need to wait until then, you would probably need to make sure the old SD card was the same size as the new one, just incase it checks that out.

It won't work... I bought some SD cards last week and swapped them out and if the info on the phone doesn't match the info on the card, it won't keep the info each time you restart...
For instance, if you insert new sd, get the green theme like a new phone, change to orange theme, turn phone off and on, it goes back to green as its still looking for original card...

Thanks for letting us know, its a pity as it would make reflashing so much easier

Technically it won't work anyway as the sdcard would be part of the raid set that wp7 makes. You cannot just take data from one raid set and add it to another.
The sdcard in wp7 is not just used as additional storage it is treated as one big lump.

now that isnt quite true,i say quite because doing this doesnt means its just takeing it from the SD card but the idea is the same, ive done a manual backup of the data from the SD card, visible through Windows phone device manager, ie, ive gone through the application folder and copied the IsolatedStore of the programs i wanted to keep the data for.
it does mean that i still need to install the app, but i can just copy the IsolatedStore back to the correct folder which will give back all the data and original settings before the reflash.

[Q] The new 7720 ROM - Encrypted Card, What to do?

Hi,
I'm trying to keep up with the thread on the development forumm but theres to mach going on there.
Can someone please explain what's that they are saying that the rom is locking the sd card and the tonight there will be another rom?
What all this about? whats the difference between the current rom and the new one?
Thanks

it locks the sd card meaning the sd can no longer be used as a regular sd card and will only work on a windows phone 7 device

yeah, at the moment, you have two choices
use the V1 ROM and be able to upgrade your ROM, you can install android still, you can not upgrade to 7712 / 7720 AND have access to your SD card UNLESS you lock the SD card
the second choice is use V2 ROM, this will lock your SD card from the start and enable updates to be much easier
Locking the SD card means that it can not be used at all on another device, Currently there isnt any software that can format the protected portion of the card, some hardware devices can format it, Some Nokia phones, some camera
Locking is actually very useful unless you want android on the same SD card
If you do want to use Android as well then get a second SD card and pop it in when you want to use it.
WP7 its self CAN clear a protected SD card but it will keep it protected, so you can reflash new WP7 ROMS with protected SD cards without any issues at all, but it will always be protected unless you use a Nokia type device.

You can also format a locked card using your wm6.5 on hd2;-)

No, it cannot. It says it is damaged on my topaz.

A buggered up partition table can be fixed with a propper format which is what 99% of people say "fixes" a broken card.
However, a "Protected" Card can not be formatted in this way, im have a chat with the SD association at the moment to see whats what, so far it is a software limitation on the PC that is stopping us clearing that data, in short if someone writes a program to do it, it will do it, the question is how!

can you guys see the partition on a PC partition app but not modify it? Or can you not even see the partition?

if a SD card has been locked its essentially unreadable in anything but the device that it was locked in, if you plug a locked (protected) SD card in a PC it will be detected in device manager but windows will not beable to access it, the SD association is a bit vague in their replys but apparently some OSs are able to format a protected card, MS isnt one of them unless there is undocumented flags that can be used at the command prompt, the best bet is probably Linux, I hate using Linux as a desktop but i do have it running as a VM server so i might give that a try a bit later
The funny thing is, its not complicated to do it (apparently) its just no one has really used the protected feature set of the SD standard
Also, (apparently, some SD cards use the protected area to store information other than the encryption key for the whole card, apparently this information might be used in read /write operations on the card, clearing the protected area to remove the SD card lock might have a negative impact on the cards performance.

Sorry, but it is confirmed. Windows Mobile 6.5 can not. Apparently Ubuntu does, I am testing!

Interesting. I did a few experiments and a whole heap of reading about this yesterday (Osx doesnt recognise the card either btw):
The card became locked during the update process from 7712 to 7720 during one of the many hard resets i did whilst installing the cabs (the sd fix cab was the last cab i installed). My mistake was not bothering to change the language from its default (English USA to English UK) so it would appear the card is also not only locked to a particular device but its language also.
One could test this by inserting the card, hard resetting and choosing USA as its language, however, it took 4 hours to get the device working to 7720 so im not doing that just yet; so i tried something else.
I put the encrypted card into my hd2, entered magldr and cleared the partition using services. I then entered usb mass storage and connected the device to my PC (win 7 x64). Whilst the card was not recognised in "my computer", if you look in camera&scanners in control panel, you will see magldr is recognised as a mass storage device but the device drivers for this fail to install properly. This is probably due to the "unknown" partition taking up the full capacity of the micro sd card and why it is not recognised by the PC hence it cannot be used for storage.
Unfortunately this also means no partition software will recognise the card, nor is it recognised in any digi camera, even after allegedly clearing the partitions via magldr.
I then had a thought would a nokia emulator work in unlocking the card? to which i havent researched any further as yet.
**EDIT** Apparently someone has decrypted and formatted a card using Ubuntu, im off to download and try it
**EDIT 2** not having much luck with ubuntu either, card not recognised........

same here, ubuntu disk manager (11.04 32-bit) shows sd card but 2.2 TB and can't format the drive or volume (i tried the same to clear mbr using magldr), ubuntu is not working

WEll, they havent been much further use, all they say is that is perfectly possible to do with software, the APIs have been there for years, its just that no one has ever really paid much attention to it, with the exception of Sat-Navs, professional Music gear etc.
Ive not had a chance to play with Linux yet but i would imagin that you need to think lower level than partition / MBR levels
From what i can gather from their cryptic responses is that when a SD card is setup to use the Secure feature, the device creates a key in the secure section, only that device can then access that section, the storage space on the card is then encrypted using that key, there is no way short of cracking the key to get access to either the secure section or the storage section. However, when you use an OS or Utility that makes use of the Secure protected area its possible to clear it, this would clear all the data obviously off the card, even disk analysers wouldnt be able to see it as it would still be encrypted.
What is concerning is that the Manufacturers have grown used to this special area and use it, apparently this area is used for IO operations, (probably some kind of cache or superfetch) this speeds things up by predicting what you are going to access next
What concerning is, if you have a class 10 device that as we all ready know uses methods to speed up sequential speeds to get that class rating, IF we manage to clear that protected area will the card be effected in terms of speed, conversly, could it improve random access speeds (WP7 essential) if its not farting around trying to predict sequential IO ops!

I'm going to try as well. If we can just get a recognition/copy to work, then we can do dual-boot again. There has to be some way to copy the entire partition.

read it again,
note the big "AND"
you can not dual boot Mango 7712/7720 and android on V1
you can not dual boot at all with V2
you cant copy encrypted partitions, it doesnt work that way, its not like making a encrypted folder, its on a much lower level than that, its either encrypted or its not, you either have Mango or you have Nodo AND android
I still cant get the Protected SD formatted, im wondering if its reliant on the card reader supporting those commands.....

Mm the secret I think is gaining access to the hidden part of the card that contains the encryption key. I'm still working on Ubuntu and have a lead to follow up on.
Your right about the droid dual boot, this isn't my intention so others shouldn't get their hopes up ;-)

[Q] Moving ROM from SD to another

Hi,
I have question , I installed the a NAND ROM using 4GB SD card but I need more space so I purchased new SD with 8GB space.
How can I transfer the part of ROM installed on the SD from the old one to the newly purchased one without losing any data.

If I were in your shoes, I'd make a full backup of my Current ROM with the old sd in. Then, I'd insert the new card and restore the back up. (of course after making the required partition).

The phone will not hang if you've got the ROM correctly on NAND. Also, try making both partitions primary, and windows on the pc will not be able to read the ext partition.

Why are you removing it while the device is on?
You should do this:
Keep Original SD card in
Boot Phone into CWM and make a back up
After it finishes, Turn off phone, put old sd card in PC, copy recent back up there, remove old and put new sd in pc and copy the back up to it
After making the partition on the new sd, put it (the new card) in your phone and boot up
Go to CWM, and restore your recently made backup
after it's done, reboot phone normally
Also, do not remove the sd-card while the phone is active ..
Because we, eu users, need some system files to be on the card and by removing it the device may become inoperative .

[Q] SD card Not Showing - Ultra Noob Here :S

Received my first HTC through the post yesterday and joined the site in an attempt to run android. I know nothing and there's an overwhelming amount of information on this site so just need someone to point me in the right direction.
Used this and followed instructions carefully: http://forum.xda-developers.com/showthread.php?t=957652
My problem is after running clrcad.exe and haret.exe, the phone reset after a grey screen. Looked like it went well but now the SD card has disappeared from the file explorer and windows when connected through USB.
Any help appreciated, just want to get the SD card back up so I can format it and so on. Thanks.

I take it by the lack of replies that this isn't a common problem. It's kind of put me off trying any new ROM's as a simple procedure like this can't even go straight. Will have to stick with Winmo then

Im not quite sure anymore, but i dont think you are able to mount your sd as long as you use sd builds. I dont know if this is changing with an ext partition on your sd.
Just check out the NAND section. Its installed on your internal memory and not running from sd. WinMob will be fully deleted and replaced with Android, so first do a backup of contacts etc!!!
If you do not need WinMob for any kind of apps for work etc which arent ported to Android yet (which i dont think there are much NAND is the best solution for you.
Started like you with sd build 2years ago, too. But switched to NAND as soon as it was stable.
Now it is almost perfect.

How did you get the card to show again? Or did you buy a new one?

Just a thought,have you tried a soft reset? Switch phone off Take back cover of and press little red button for a few seconds,put cover back on reboot into android
Also make sure your SD card is formatted to 32kb (slow format)

How to recover data from encrypted ext SD?

Month ago, I dropped my phone in the sea. Tried the rice trick and the alcohol baptism - neither of which worked.
Only thing that happens to it now, is when I press power, it vibrates once, blue light indicator also comes up, and after few seconds it goes off again. Looks like salt, really did its magic somewhere inside the circuit.
My problem is that I need to recover some photos (which I haven't had the chance to backup...) from the ext SD card that I was using with the phone. Card was encrypted using Android's (6.0.1) own build-in option. Which means it can only being read/de-crypted on that particular phone. So, my only chance, if any, is to resurrect the S5. Screen is probably gone, especially after the alcohol dip, the cable connecting the screen with the remaining circuit, detached itself. I can afford to spend little money (i.e. for a non-genuine screen), but I m not sure what else is damaged. Home button doesn't look like it's functioning either...
I am not sure if there are any backdoors to that encryption. I just always thought its stupid to have hardware-based encryption. It should be password-based!
All I need is the data on that SD card. How can I proceed?
(only thing left that I have in my mind, is to try another battery, in case mine is also damaged from the water)
I did searched here, but found nothing relevant, except something about using ADB (which I m not sure it ll help) Any ideas?

It's protected by the ROM. Not even the phone itself. So no it won't work. But on PC there's apps like EaseUs that can copy the data off.

Copy? Yes, I ve read about that.
But how to decrypt? Encrypted data is of little use...

Got a backup of your phone by chance?

You mean the contents of the SD Card? Yes!
I used a microSD adapter and copied all the contents of the ext sd card to my PC. But obviously, data is encrypted, so I can't actually view my pictures
btw - there's no point in using any 3rd party tools (i.e. easeus, recuva etc) as they won't decrypt the files anyway...all you can do it just copy them over - which I did. Now what?
So - back to your question - there's nothing else I need from that phone. Except from my pictures (which I already backed up, in their encrypted form...)
In the meantime, I found this: http://www.forensicswiki.org/wiki/How_To_Decrypt_Android_Full_Disk_Encryption
but I m not in a position to follow that, as the screen doesn't seem to work and the phone won't boot. Upon powering up, blue light comes up for few secs, and then it turns off again.
I think I ll need to fix the hardware issue(s) first and then properly boot and decrypt the card :/
But I can't afford to format the phone (as I won't be able to decrypt the sd card afterwards - correct?)

Depends. What was it running for a ROM?

If I m not mistaken, the encryption used is based on hardware (not the actual ROM). Or a combination or both. Otherwise it would defeat it's purpose i.e. anyone with the same phone model + same ROM build would decrypt an ext sd card....

It can't be. People upgrade their ROM and lose access to the SD. Did you backup your phone? Use that to emulate the ROM. I usually back up everything including system and modem
