Help! I have an XDA IIs which was working fine for the last two years. It has a 1GB SD Card in there. I used it for TomTom all this time, with no problems at all.

A couple of days ago, I forgot to grab my device from the car as I was in a rush and I left it in the car (powered off, but with TomTom running) most of the day.

When I got back in the car, TomTom wasn't working right so I closed it and tried to re-open it, whereupon I received the nasty message "Cannot determine location of data".

To put it simply, the device no longer recognises the presence of an SD Card! It's not in File Explorer, nor under Settings / Memory / Storage Card.

What is going on?

Here's a list of what I've tried already (none of these ideas has solved the issue):

o Tried a different SD Card

o Tried a soft reset on the device

o Tried a hard-reset on the device

o After hard-reset, tried a restore from a recent Active Sync backup-to-PC.

o Downloaded PocketPC Mechanic and played around A LITTLE (didn't do anything that seemed dangerous like defragging, registry cleaning, etc)

Any help will be VERY gratefully received!

Thanks

Matt

Update... but still have problem

Quick update

I also tried formatting the SD Card. No help (I have since copied all data back onto the card and it still doesn't work).

Apparently, the motherboard your device is dies slowly.
[MDA III, XDA III, PDA2k, 9090 General] rafa1215:
Have you tried a diifferent sd card? reinstalling the software all over again?
[MDA III, XDA III, PDA2k, 9090 General] mattyboy:
Replying to Rafa1215

Yes, I have tried a different SD Card (as noted in the original post, list of things I have tried). It's a 128MB one which works fine in the SD Card reader slot on my PC (my main 1GB card works fine in PC slot as well).

Here's a further titbit of information which may or may not be useful in helping me:

I've tried several times to restore the backup-to-PC I made at the end of April (essentially the same stuff on the device then as now, luckily). Normally, when you insert (or remove) the card, it turns the screen on. Each time I perform the restore (of the same backup, over and over again), the SD Card slot actually performs this function when I insert the card again - but ONLY ONCE each time I restore from backup.

As for reinstalling software all over again... I have performed a hard-reset on the device, and tried the card as soon as it is ready to use... no luck there either.

In reply to vovaxxxx:

Is that a serious comment? The motherboard slowly dies? If that's true then this device is fit for nothing but the rubbish bin! :(

More ideas are welcome please, I thank you for the feedback!! :)
[MDA III, XDA III, PDA2k, 9090 General] LGSilva:
If you're luck enough to have a friend that have a BA you could test his sd card on your BA and your sd card on his BA. If his BA can read your card and yours can't read his then you have 2 situations:

1) Your sd card slot is dirty or slightly melted so you have no good contacts, try to clean it.

2) Time to buy a new phone or try to buy a new circuit board for your phone but for the price I think is better you get a new phone.

Edit: If you have $100 you can get a new circuit board here: http://xdaforums.com/showthread.php?t=310283
[MDA III, XDA III, PDA2k, 9090 General] xplode:
search google for panasonic sd formatter or something like this, this is a lil program which is used to format your SD properly. Insert your SD card into the card reader, start the program and reformat the SD card.

The problem is within the SD card file system
[MDA III, XDA III, PDA2k, 9090 General] rafa1215:
If that doesn't work try

Storage Tools by softwinter.com

You can at least do a Scandisk and fix any errors during the scan
[MDA III, XDA III, PDA2k, 9090 General] mattyboy:
OK I formatted the SD card with the Panasonic formatting utility. (Backed everything up to the PC first, from the card!)

Still no difference. To reiterate - the SD Card(s) I am trying to use are working fine in my PC's SD Card reading slot.

I think it's the hardware (i.e. the XDA itself)... LGSilva says I could try cleaning the contacts. Any recommended ways on doing this? The slot is too small to get any kind of decent cleaning implement in there, and I can't dismantle the device because it's held together with special screws (6-pointed-star-shaped heads).

Hi

the company i work for has around 300 device and this happens every now and again. not sure if this will help but normally call our mobile network and get a replacement. it's normally the card reader in the device.
[MDA III, XDA III, PDA2k, 9090 General] mikealder:
The screws are size 6 Torx bits, suitable sets of these drivers can be bought from Maplins in the UK, although you don't mention where you are located.

There is also a guide to taking the BA to bits in the WiKi and a very comprehensive one containing pictures etc. at the bottom of the WiKi page, well worth reading both before you try taking it to bits - Mike

I read online that lg pc suite will allow you to upgrade the phone too android lollipop BUT when i hit upgrade it tells me "mobile device software upgrade is blocked on no upgrade policy" what does this mean? i am running a stock untouched tmobile rom im just rooted. Also is it besster to revert to stock using a zip or a TOT because i used a ZIP file and it works fine.
[T-Mobile LG G3] Still_living714:
If you are rooted just flash recovery(trwp) and update to lollipop through twrp. If you want to revert back to stock kitkat in the future back sure to backup everything including the efs.
[Xperia Z3 Q&A, Help & Troubleshooting] trenty12:
Just got a Z3 a couple of days ago and installed the generic UK firmware and all is good!

I have just come across an issue though where some apps dont seem to show as having an update available in the play store or whats new.

Basically, i wanted to move some photos from one folder to another and noticed i couldnt do it. A quick google suggests that the latest version of Album allows it, so i went into album on play store and it was there, the update button was available.

However this was not under the 'updates' section. Im now wondering if a number of my other apps have updates available without me knowing and i dont fancy going into each and every one to find out.

Am i missing something?
[Xperia Z3 Q&A, Help & Troubleshooting] gregbradley:

Thanks, but I ws able to update it through the play store :)

What im saying is, why was it not showing that an update was available? Am i missing something in the settings or something?

I dont want there to be other apps that have an update but i dont know about
[Xperia Z3 Q&A, Help & Troubleshooting] Incanity:
Could be because of regional differences that you get an update a bit later than others. The fastest way of getting the latest updates is to check here... There's always someone that got the update before you that's willing to share it with us :)
[Xperia Z3 Q&A, Help & Troubleshooting] Webern:
Why is nobody reading the poor guy's question properly? The update WAS available, but only when he looked in the play store, not in the updates section.
[Xperia Z3 Q&A, Help & Troubleshooting] Incanity:
If the app was restored by a backup program or installed or updated from a third party source, play store won't always put the app in the 'my apps' section, therefore, not showing it as updatable. Try reinstalling the app from the play store.

[Android General] Quinny899:
There's a hidden feature in Android 6.0, multi window. It has its warnings:

So decide if this is actually for you before following these steps

It's not shown in user builds, so we have to do some messing. You'll either need root or a custom recovery to do this, but as not everyone wants root, here's how you do it with TWRP, a USB cable, and a PC with ADB:

1. Boot your device into recovery

2. Mount your system by going to Mounts > Tick System

3. On your PC open a command line, somewhere like your desktop is useful

4. Type the following command:

adb pull /system/build.prop

5. Open the build.prop file with your favourite (decent) editor, I recommend using Notepad++ on Windows

6. Find the "ro.build.type" line

7. Change the text after = to "userdebug" from "user"

BONUS: If you want a nicer DPI here, change the line "ro.sf.lcd_density" to your preferred DPI

8. Save the file

9. Go back to the command line and enter the following command:

adb push build.prop /system/

10. Now open a shell doing:

adb shell

11. Now a adb shell will open, enter these commands:

cd system
chmod 644 build.prop

12. Reboot the device as normal

13. When the device has booted, go to the developer options

14. Scroll down to the bottom of the "Drawing" category

15. Enable multi-window and have some fun!

If you're rooted...

1. Download "Build.prop editor"

2. Find "ro.build.type"

3. Edit it to have the value "userdebug" from "user"

4. Reboot when prompted

5. When the device has booted, go to the developer options

6. Scroll down to the bottom of the "Drawing" category

7. Enable multi-window and have some fun!
[Android General] F4uzan:
Worked ! Thanks :D

Such a shame the Keynote didn't introduce such feature, it's stable enough. Just think of the use of the feature on a 10" tablet.
[Android General] castaway1:
works perfect thank you !
[Android General] Chahk:
How do you use it after enabling?
[Android General] bradputt:
Go recent menu, on the apps beside the x there's a button to choose the top half or second half.

Multirom users can go /data/media/multirom/roms/ and edit the build prop directly there, no need to use adb. I did it without using a PC
[Android General] prwnd:
I flashed the latest hammerhead twrp with fastboot command, it was successful, but when I reboot bootloader and choose recovery, it keeps loads forever and sometimes the screen flashes black. I tried CWM after that, it said root needed. How do you guys got recovery on M?

Hello people, I have multirom installed on my nexus 5, the primary rom is 5.1.1 (LMY48B), and my secondary rom is the developer preview MPZ44Q. I want to know if it's possible to enable multi-window mode since the M preview is installed as secondary rom.
[Android General] kidhudi:
I did it. Reboot into recovery. Swap the Roms. Don't reboot . reboot into recovery again from the reboot tab. Select multiboot tab just to ensure you are OK and the M ROM is the internal.. Mount system and do what the op says. Reboot into recovery again swap Roms again . reboot system and you should be OK. Takes like a half an hour to do though

PS. NEVER FIX SU. ALWAYS SKIP
[Android General] theCrazyDev:
I understood that if i try to install su on the M rom, it will result in bootloop. And my internal rom is stock ROOTED. So do you think it will work ?

When i will swap the roms, the fact that my primary rom is rooted, will it cause any problem ? Thanks in advance.
[Android General] kidhudi:
Nope my primary is still rooted. And I an typing this from my secondary M ROM with multi window enabled. All you have to do is never fix su for either ROM and never boot the system with M as your primary ROM and you are ok
